(Summary) Although erosive esophagitis (EE) is associated with fatty liver and metabolic dysregulation, the association between EE and metabolic dysfunction-associated steatotic liver disease (MASLD) remains unclear. Thus, this study aimed to investigate the longitudinal association between MASLD and EE. We included 1578 patients without EE at baseline who underwent more than two health checkups over 2 years. Generalized estimation equations were used to analyze associations between MASLD and EE according to repeated measures at baseline and most recent stages. EE development rates in men and women were 14.5% and 7.2%, respectively. After adjusting for lifestyle habits, the odds ratios of MASLD for EE development in men and women were 1.907 (95% confidence interval [CI]: 1.289-2.832, P < 0.005) and 1.483 (95% CI: 0.783-2.811, P = 0.227), respectively. In the subgroup analysis, after adjusting for lifestyle habits, among men and women aged 50 years with more than three MASLD components, the odds ratios for EE development were 2.408 (95% CI: 1.505-3.855, P < 0.001) and 2.148 (95% CI: 1.093-4.221, P < 0.05), respectively. After adjusting for various factors, the significant risk factors for EE development were different between men and women. The influence of MASLD and other factors on EE development differed by sex and age. Particularly, patients aged 50 years with MASLD and with an increased number of MASLD components should be considered at increased risk for EE.

(Summary) Although body weight reduction is recommended to ameliorate nonalcoholic fatty liver disease, the effects of body mass index (BMI) and waist circumference (WC) variability on newly achieved remission of metabolic dysfunction-associated fatty liver disease (MAFLD) remain unclear. We aimed to investigate the longitudinal association between BMI and WC variabilities and newly achieved MAFLD remission in both sexes. Among 26,952 patients, 1823 with MAFLD diagnosed by ultrasonography and with >2 health checkups over >2 years from April 2014 to March 2021 were included in this observational cohort study. A generalized estimation equation model analyzed the association between BMI and WC and newly achieved MAFLD remission according to repeated measures at baseline and the most recent stage. Rates of MAFLD remission in male and female patients were 7.4 % and 6.0 %, respectively. Regarding decreased BMI variability, newly achieved MAFLD remission prevalence among the subgroups differed significantly between sexes (p < 0.001). In male patients, a decrease in BMI variability of ≥1.5 kg/m and WC variability of ≥4.2 cm had adjusted odds ratios (ORs) of 5.215 and 2.820, respectively, for newly achieved MAFLD remission. Among female patients, regular exercise and breakfast consumption were accelerating factors for newly achieved MAFLD remission. Non-invasive liver fibrosis scores significantly differed between MAFLD and newly achieved MAFLD remission, including in the subgroups (p < 0.01 and p < 0.001, respectively). Reducing BMI and WC variabilities in male patients and improving lifestyle habits in female patients may accelerate MAFLD remission.

(Summary) The influence of alcohol intake on metabolic dysfunction-associated fatty liver disease (MAFLD) development and remission remains unclear; thus, we aimed to investigate their longitudinal associations. This observational cohort study included 6349 patients who underwent more than two health check-ups over >2 years between April 2013 and March 2021. Generalized estimation equations were used to analyse the longitudinal associations between changes in alcohol intake and MAFLD according to repeated measures at baseline and the most recent stage. The MAFLD development and remission rates were 20.4 and 5.1 and 9.1 and 4.7% in men and women, respectively. Although alcohol consumption was not a significant factor for MAFLD development, consuming 0.1-69.9 g/week (odds ratio [OR]: 0.672, 95% confidence interval [CI]: 0.469-0.964, p < .05) and ≥280 g/week were significant factors for MAFLD development in males (OR: 1.796, 95% CI: 1.009-3.196, p < .05) and females (OR: 16.74, 95% CI: 3.877-72.24, p < .001). Regardless of quantity and frequency, alcohol consumption was not a significant factor for MAFLD remission. Several noninvasive liver fibrosis scores were significantly associated with alcohol intake quantity and frequency in males with MAFLD development and remission (p < .05). The nonalcoholic fatty liver disease fibrosis score differed significantly between males with and without reduced alcohol intake (p < .05) who showed MAFLD remission. Although the influence of alcohol intake on MAFLD development and remission differed, alcohol consumption was not beneficial for MAFLD remission in either sex. Alcohol intake reduction or cessation is recommended to prevent liver fibrosis, even in those who achieve MAFLD remission.

(Summary) The influence of metabolic dysfunction-associated fatty liver disease on gallstone development remains unclear. We aimed to investigate the longitudinal association between metabolic dysfunction-associated fatty liver disease and gallstone development in both men and women. This observational cohort study included 5398 patients without gallstones who underwent > 2 health check-ups between April 1, 2014, and March 31, 2020. A generalized estimation equation model was used to analyze the association between metabolic dysfunction-associated fatty liver disease and gallstone development according to repeated measures at baseline and most recent stage. After adjustment, the odds ratios of metabolic dysfunction-associated fatty liver disease for gallstone development in men and women were 3.019 (95% confidence interval [CI]: 1.901-4.794) and 2.201 (95% CI: 1.321-3.667), respectively. Among patients aged 50 years, the odds ratio for gallstone development was significantly enhanced with increasing metabolic dysfunction-associated fatty liver disease component numbers in both sexes; however, no significance was observed in those aged < 50 years. Other significant risk factors for gallstone development were age (odds ratio: 1.093, 95% CI: 1.060-1.126) and waist circumference (odds ratio: 1.048, 95% CI: 1.018-1.079) in men and age (odds ratio: 1.035, 95% CI: 1.003-1.067) and current smoking (odd ratio: 5.465, 95% CI: 1.881-15.88) in women. Although the risk factors for gallstone development differed between sexes, metabolic dysfunction-associated fatty liver disease was common. Paying attention to an increase in the number of metabolic dysfunction-associated fatty liver disease components in patients aged 50 years is important for gallstone prevention.

(Summary) The influence of changes in alcohol consumption on newly developed metabolic dysfunction-associated fatty liver disease (MAFLD) is unclear. We investigated the influence of alcohol consumption on newly developed MAFLD in both sexes. This observational cohort study included 4071 patients who underwent more than two health check-ups between 2015 and 2020 over an interval of more than a year. Generalised estimating equations were used for analyses. At baseline, the rates of drinking and MAFLD between men and women were 72.5% versus 41.7% and 42.2% versus 22.1%, respectively. At the most recent stage, the rates of an increase in alcohol consumption for men and women were 13.3% and 8.7%, respectively, and 311/1192 (26.1%) men and 155/1566 (9.9%) women had newly developed MAFLD. The odds ratio (OR) for drinking in patients with newly developed MAFLD was 0.863 (men) (95% confidence interval [CI], 0.676-1.102, p = 0.237) and 1.041 (women) (95% CI, 0.753-1.439, p = 0.808); the OR for women who drank 140-279.9 g/week was 2.135 (95% CI, 1.158-3.939, p < 0.05) and that for all drinking categories among women was >1. Several non-invasive fibrosis scores were significantly associated with the quantity of alcohol consumption in patients with newly developed MAFLD (p < 0.005). Alcohol consumption had no significant protective effect against newly developed MAFLD in both sexes, regardless of quantity. Conversely, alcohol consumption ≥140 g/week was a risk factor for newly developed MAFLD in women. The development of liver fibrosis with increased alcohol intake should be considered in patients with MAFLD.

(Summary) Although several angiogenesis-related factors are reportedly involved in the pathogenesis of ulcerative colitis (UC), the mechanisms by which they contribute to disease are unclear. We first examined the expression of angiogenesis-related factors in inflamed colorectal tissue of UC patients using antibody array, and identified the 5 factors with highest expression, which included matrix metalloproteinase-8, urokinase-type plasminogen activator (uPA), angiostatin/plasminogen, hepatocyte growth factor and endoglin. Subsequent real-time PCR experiments using additional colorectal tissues revealed that uPA mRNA levels were significantly higher in inflamed tissues than in non-inflamed tissues, and significantly correlated with the severity of UC. Mirror section immunohistochemistry revealed that uPA was expressed in the neutrophils of inflamed colorectal tissues. We administered dextran sulfate sodium (DSS) in drinking water to uPA knockout (uPA) mice, and found that the disease activity index in uPA mice was marginally lower and the histological score in uPA mice was significantly lower than those in wild-type mice, suggesting the importance of uPA in colitis. When an uPA-selective inhibitor, UK122, was administered to DSS-treated C57BL6J mice, the disease activity index and histological score in those mice were significantly lower compared with control mice. Multiple cytokine/chemokine assay using colorectal tissues from uPA and UK122-treated mice revealed significantly lowered level of RANTES. In conclusion, uPA was highly expressed in neutrophils of the inflamed mucosa of UC patients, and the expression level correlated with the severity of UC. Genetic uPA deletion or pharmacological uPA blockade significantly ameliorated colitis in mice, concomitant with downregulation of RANTES.

(Summary) The influence of changes in alcohol consumption on erosive esophagitis (EE) development in both sexes is unclear. This observational study investigated sex differences in the influence of alcohol consumption on EE development, and included 2582 patients without EE at baseline from 13,448 patients who underwent >2 health check-ups over >1 year. The rates of non-drinkers who started drinking, and drinkers who abstained from drinking, who increased, and who decreased their weekly alcohol consumption were 7.2%, 9.7%, 14.7%, and 24.1% and 7.3%, 17.8%, 12.8%, and 39.0% in men and women, respectively. In the final cohort, 211/1405 (15.0%) men and 79/1177 (6.7%) women newly developed EE. The odds ratio (OR) for drinking in EE development was 1.252 (95% confidence interval (CI), 0.907-1.726) among men and 1.078 (95% CI, 0.666-1.747) among women. Among men aged <50 years, the OR for drinking ≥70 g/week in EE development was 2.825 (95% CI, 1.427-5.592), whereas among women, the OR for drinking ≥140 g/week in EE development was 3.248 (95% CI, 1.646-6.410). Among participants aged <50 years, the OR for daily drinking in EE development was 2.692 (95% CI, 1.298-5.586) among men and 4.030 (95% CI, 1.404-11.57) among women. The influence of alcohol consumption on EE development differed between the sexes. We recommend no alcohol consumption for individuals aged <50 years to avoid EE development. Daily drinkers should be assessed for EE development.

(Summary) The clinical difference between nonalcoholic fatty liver disease (NAFLD) and metabolic-associated fatty liver disease (MAFLD) between the two sexes is unclear. This study aimed to determine the influences of alcohol consumption and qualitative abdominal fat between male and female patients with NAFLD and MAFLD. This cross-sectional study examined 11,766 participants who underwent health check-ups comparing lifestyle habits, biochemical features, and noninvasive liver fibrosis scores, between non-MAFLD and MAFLD groups. Furthermore, differences in alcohol consumption and qualitative abdominal fat were examined between male and female patients with NAFLD and MAFLD. The prevalence of metabolic dysregulation, ratio of visceral fat area to subcutaneous fat area, and noninvasive liver fibrosis scores were significantly higher in male patients with MAFLD than in those with NAFLD (p < 0.05), but these were not significantly different in female patients. Among male patients with an alcohol consumption of > 70 g/week, several noninvasive liver fibrosis scores were significantly higher in the MAFLD group than in the NAFLD group (all p < 0.05).

(Summary) Esophagogastroduodenoscopy (EGD) has become an indispensable examination to discover upper gastrointestinal diseases, including cancer, and perform endoscopic treatment. However, many individuals who undergo the procedure have feelings of anxiety and fear regarding EGD. Although the use of medication for sedation during EGD is useful for reducing anxiety and the stability of hemodynamics, sedation may increase the likelihood of complications. Several noninvasive distractions have been introduced to decrease pain and anxiety during endoscopic examinations;however, most assessments of these distractions evaluated subjective items such as impression. We herein add the results of our studies using objective items and review the effectiveness of distractions for EGD. J. Med. Invest. 69 : 8-18, February, 2022.

(Summary) The prevalence of nonalcoholic fatty liver disease (NAFLD) in the non-obese population has increased and NAFLD is not always recognized in individuals with metabolic syndrome (MS). The risk of cirrhosis is higher in patients having NAFLD with elevated alanine aminotransferase (ALT) levels than in those having NAFLD with normal ALT levels. To measure the differences in clinical factors associated with NAFLD having elevation of ALT among subjects with Non-MS, Pre-MS, and MS, and to measure differences in metabolites between MS subjects with and without NAFLD having elevation of ALT. Among 7,054 persons undergoing health check-ups, we included 3,025 subjects who met the selection criteria. We measured differences in clinical factors for NAFLD having elevation of ALT among subjects with Non-MS, Pre-MS, and MS, and compared metabolites between subjects with and without NAFLD having elevation of ALT in 32 subjects with MS. The prevalence of NAFLD and NAFLD having elevation of ALT was significantly progressively greater in subjects with Non-MS, Pre-MS, and MS (p <0.001, respectively). In the Non-MS group, there were significant differences between subjects with and without NAFLD having elevation of ALT with respect to body mass index (BMI), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, hemoglobin A1c, uric acid, aspartate aminotransferase (AST); In the Pre-MS group, there were significant differences in BMI, hypertension, AST, and gamma-glutamyl transpeptidase (GGT); In the MS group, there were significant differences in HDL-C, impaired glucose tolerance, AST, and GGT. There were significant differences in levels of metabolites of nicotinamide, inosine, and acetyl-L-carnitine between MS subjects with and without NAFLD having elevation of ALT (all p <0.05). Although NAFLD having elevation of ALT is important for development of NAFLD, differences in factors associated with NAFLD having elevation of ALT at various stages of MS should be considered. Additionally, several metabolites may play roles in the identification of risk for NAFLD in individuals with MS.

(Summary) Cell-free and concentrated ascites reinfusion therapy (CART) is an effective therapy for refractory ascites. However, CART is difficult to perform as ascites filtration and concentration is a complicated procedure. Moreover, the procedure requires the constant assistance of a clinical engineer or/and the use of an expensive equipment for the multi-purpose blood processing. Therefore, we developed a CART specialized equipment (mobility CART [M-CART]) that could be used safely with various safety measures and automatic functions such as automatic washing of clogged filtration filter and self-regulation of the concentration ratio. Downsizing, lightning of the weight, and automatic processing in M-CART required the use of newly developed multi-ring-type roller pump units. This equipment was approved under Japanese regulations in 2018. In performing 41 sessions of CART (for malignant ascites, 22 sessions; and hepatic ascites, 19 sessions) using this equipment in 17 patients, no serious adverse event occurred. An average of 4494 g of ascites was collected and the total amount of ascites was processed in all the sessions without any trouble. The mean weight of the processed ascites was 560 g and the mean concentration ratio was 8.0. The ascites were processed at a flow rate of 50 mL/min. The mean ascites processing time was 112.5 minutes and a 106.5-minutes (95.2%) ascites processing was performed automatically. The operator responded to alarms or support information 3.2 times on average (3.1 minutes, 2.1% of ascites processing time). Human errors related to ascites processing were detected by M-CART at 0.4 times per session on average and were appropriately addressed by the operator. The frequencies of automatic washing of clogged filtration filter and self-regulation of the concentration ratio were 31.7% and 53.7%, respectively. The mean recovery rates (recovery dose) of protein, albumin, and immunoglobulin G were 72.9%, 72.9%, and 71.2% (65.9 g, 34.9 g, and 13.2 g), respectively. Steroids were administered in 92.7% of the sessions to prevent fever and the mean increase in body temperature was 0.53°C. M-CART is a compact and lightweight automatic CART specialized equipment that can safely and easily process a large quantity of ascites without the constant assistance of an operator.

(Summary) Esophagogastroduodenoscopy (EGD) provides an indispensable and unambiguous inspection allowing the discovery upper gastrointestinal lesions. However, many patients are anxious about undergoing EGD. Few studies have investigated the influence on patients' vital signs and tolerance during EGD using subjective and objective assessments. This study was a prospective randomized controlled study that investigated the influence of audio and visual distraction on EGD. We randomly divided 289 subjects who underwent EGD into 4 groups (control group, audio group, visual group, combination group) and examined their vital signs, heart rate variability (HRV), psychological items, and acceptance of distraction. Pulse rate (PR) at post-distraction and post-EGD in the 3 distraction groups were significantly lower than those of control group (p < 0.001 and p < 0.01, respectively). Blood pressure (BP) during and post-EGD was significantly higher than that at pre-EGD in control group (p < 0.05), but no significant elevation of BP was observed during the latter half of EGD and post-EGD in the 3 distraction groups. BP at post-distraction improved significantly compared to pre-distraction in the 3 distraction groups (p < 0.05). There was a significant difference in the low-frequency (LF) power/ high-frequency (HF) power at post-distraction and post-EGD among the 4 groups (p < 0.001 and p < 0.001, respectively). The LF power/HF power at post-distraction and post-EGD in the 3 distraction groups was significantly lower than that in control group (p < 0.05). Several items of profile of mood states (POMS) and the impression of EGD at post-distraction improved significantly compared to those at pre-distraction among the 3 distraction groups (p < 0.05). Visual analog scale (VAS) of willingness for the next use of distraction in the 3 distraction groups was excellent because VAS was more than 70. Distractions effectively improved psychological factors, vital signs and some of HRV at pre and post-EGD. Distractions may suppress BP elevation during the latter half of EGD and lead to stability of HRV on EGD.

(Summary) Chronic care patients undergoing hemodialysis for treatment of end-stage renal failure experience higher rates of bloodstream-associated infection due to the patients' compromised immune system and management of the bloodstream through catheters. Staphylococcus species are acommon cause of hemodialysis catheterrelated bloodstream infections. We investigated environmental bacterial contamination of dialysis wards and contamination of hemodialysis devices to determine the source of bacteria for these infections. All bacterial samples were collected by the swab method and the agarose stamp method. And which bacterium were identified by BBL CRYSTAL Kit or 16s rRNA sequences. In our data, bacterial cell number of hemodialysis device was lower than environment of patient surrounds. But Staphylococcus spp. were found predominantly on the hemodialysis device (46.8%), especially on areas frequently touched by healthcare-workers (such as Touch screen). Among Staphylococcus spp., Staphylococcus epidermidis was most frequently observed (42.1% of Staphylococcus spp.), and more surprising, 48.2% of the Staphylococcus spp. indicated high resistance for methicillin. Our finding suggests that hemodialysis device highly contaminated with bloodstream infection associated bacteria. This study can be used as a source to assess the risk of contamination-related infection and to develop the cleaning system for the better prevention for bloodstream infections in patients with hemodialysis.

(Summary) Although many patients still have anxiety about upper gastrointestinal (GI) endoscopy, there have been few reports on the influence of distractions for a person who is going to undergo upper GI endoscopy soon. This study was a prospective randomized controlled study investigating the influence of distractions, such as auditive and visual distractions using subjective and objective assessments including autonomic nervous function prior to upper GI endoscopy. 206 subjects who underwent upper GI endoscopy as regular health check-ups were divided randomly into 4 groups prior to upper GI endoscopy; group 1 (control group), group 2 (auditive group), group 3 (visual group), and group 4 (combination group). We measured vital signs, autonomic nervous function, profile of mood state (POMS), and the impression for upper GI endoscopy pre- and post-distraction in the 4 groups. There was no significant difference in vital signs between 5 and 15 min after sitting in group 1, however, several vital signs in all distraction groups improved significantly after distraction (Pulse rate (P): p < 0.001 in group 4; blood pressure: p < 0.05 in group 2, 3, 4) and the rate of decrease in P and diastolic blood pressure was highest in group 4 (p < 0.001). Several scores of POMS and the impression for upper GI endoscopy post-distraction improved significantly compared to pre-distraction between distraction groups and the satisfaction for distraction was highest in group 4 (p < 0.01). Regarding autonomic nerve function, the low- frequency power/ high- frequency power ratio post-distraction was significantly lower than that pre-distraction in all distraction groups (p < 0.001). Although auditive distraction alone and visual distraction alone were effective, a combination distraction was more effective than any other distraction by subjective and objective assessments. These distractions, which were simple and safe, may play an assistive role in the stability of physical and psychological conditions prior to upper GI endoscopy.

(Summary) It has been reported that some single-nucleotide polymorphisms (SNPs) in lipid regulators such as apolipoproteins and cell surface molecules for hepatitis C virus (HCV) entry into hepatocytes are associated with HCV infection. However, it is unknown how HCV infection is affected by altered lipid metabolism resulting from the SNPs. We investigated the relationship between these SNPs and HCV infection status, and also analyzed the mechanism by which these SNPs mediate HCV infection via lipid metabolism alterations. Serum lipid and apolipoprotein profiles were tested in 158 HCV-positive and 220 HCV-negative subjects. We selected 22 SNPs in five lipid regulator genes which were related to HCV entry into hepatocytes and to lipid metabolism (APOA1, APOB, SR-B1, LDLR, and APOE), and their polymorphisms were analyzed using the PCR-sequence-specific oligonucleotide probe-Luminex method. An APOB N4311S (g.41553a > g) SNP, rs1042034, was significantly associated with HCV positivity; the HCV positivity rate for the minor allele AA genotype was significantly higher than for genotype AG + GG (P = 0.016). Other SNPs except for APOB P2712L SNP rs676210, which is in linkage disequilibrium with rs1042034, showed no significant difference in genotype distribution. The serum level of low density lipoprotein-cholesterol (LDL-C) in the genotype AA group was significantly lower than in the genotype non-AA group (P = 0.032), whereas the triglyceride (TG) level was significantly higher (P = 0.007). An APOB SNP, rs1042034, is closely associated with HCV infection through lipid metabolism alteration. The minor allele AA genotype might contribute to facilitating serum LDL uptake into hepatocytes via LDLR by modifying their affinity and interaction and may have an influence on HCV infection by their entry to the liver through the LDLR.

(Summary) Anti-EGFR mAb is reported to induce EGFR internalization in colorectal cancer cells. However, the biological relevance of EGFR internalization with anti-EGFR mAb is unknown. Therefore, the relevance of EGFR downregulation with anti-EGFR mAb to antitumor activity in colorectal cancer cells was investigated. Quantification of EGFR on the cell surface before cetuximab treatment was assessed by flow cytometry, and its growth-inhibitory effects were measured by Trypan blue exclusion, in 10 wild-type colorectal cancer cell lines, but there was no significant correlation between EGFR number and its growth-inhibitory effect. However, a significant correlation existed between the percentage decrease in the number of EGFRs after cetuximab treatment and its growth-inhibitory effect in those cell lines. Treatment with TGFα, a ligand for EGFR, induced EGFR internalization in colorectal cancer cells, but most EGFRs subsequently recycled to the cell surface, consistent with previous studies. While cetuximab treatment induced EGFR internalization, most receptors subsequently translocated into the late endosome, leading to lysosomal degradation, as revealed by immunoblotting and double immunofluorescence. Cetuximab-sensitive colorectal cancer cells showed greater EGFR internalization, stronger cell growth inhibition, and more augmented apoptotic signals than nonsensitive cells. IHC for EGFR, performed using an EGFR pharmDx Kit (mouse anti-human EGFR mAb clone 2-18C9), in clinical specimens before and after anti-EGFR mAb therapy in 13 colorectal cancer patients showed a significant correlation between the response to anti-EGFR mAb and decreased staining after therapy. This report clearly demonstrates that anti-EGFR mAb facilitates internalization and subsequent degradation of EGFRs in lysosomes, which is an important determinant of the efficacy of anti-EGFR mAb treatment for colorectal cancer. .

(Summary) study, the effects of phosphate on proinflammatory cytokine induction and reactive oxygen species production in RAW264.7 macrophage were examined. Dietary phosphate exacerbated intestinal inflammation in experimental colitis in a dose-dependent manner, as assessed by the clinical disease activity score, colon length, and histology. Furthermore, the high phosphate diet increased myeloperoxidase activity and proinflammatory cytokine mRNA expression through the activation of nuclear factor B in the inflamed colon. In addition, high phosphate loading in RAW264.7 cells directly enhanced reactive oxygen species production and proinflammatory cytokine gene expression. Our results demonstrated that the high phosphate diet exacerbated intestinal inflammation in experimental colitis. These findings have important therapeutic implications for inflammatory bowel disease patients.

(Summary) Nonalcoholic fatty liver disease (NAFLD) is known to be strongly associated with obesity, visceral fat, metabolic syndrome (MS), lifestyle, and lifestyle-related diseases in both males and females. However, the prevalence of NAFLD, MS, and clinical backgrounds is different between males and females. We conducted a cross-sectional study to examine the differing influence of lifestyle-related factors and visceral fat on fatty liver (FL) with elevation of liver enzymes between males and females with MS. We enrolled 42,134 persons who underwent a regular health check-up, and after excluding subjects who fulfilled excluding criteria, the remaining subjects were 2,110 persons with MS. We examined the differing influence of lifestyle-related factors and visceral fat on FL with elevation of alanine aminotransferase (ALT) (ALT elevation was defined as ALT level of ≥31 IU/l in the present study). The odds rations for FL with ALT elevation were as follows: WC, 1.83 (95% confidence interval (CI) 1.36-2.46); dyslipidemia, 1.89 (95% CI 1.34-2.68); hemoglobin A1c, 1.36 (95% CI 1.00-1.85); visceral fat type MS (V-type MS), 5.78 (95% CI 4.29-7.80); and light drinker, 0.56 (95% CI 0.41-0.78) in males with MS and BMI, 2.18 (95% CI 1.43-3.33); WC, 1.85 (95% CI 1.27-2.70); diastolic blood pressure, 1.69 (95% CI 1.16-2.45); triglyceride, 2.22 (95% CI 1.56-3.17); impaired glucose tolerance, 1.66 (95% CI 1.11-2.47); and V-type MS, 3.83 (95% CI 2.57-5.70) in females with MS. The prevalence of FL with ALT elevation and ALT was significantly higher in V-type MS than in the subcutaneous fat type MS in both males and females with MS (P < 0.001). Although V-type MS and WC is a common significant predictor of an increased prevalence of FL with ALT elevation in both males and females with MS, gender, lifestyle-related factors, and MS type in individuals with MS should be considered for the development of FL with ALT elevation.

(Summary) Although des-gamma-carboxy prothrombin (DCP) is a well-known tumor marker for hepatocellular carcinoma (HCC), the mechanism of DCP production is unclear. This study aimed to investigate the mechanism how DCP is produced in HCC cells. Levels of mRNA and DCP were analyzed by real-time polymerase chain reaction and electro-chemiluminescence immunoassay respectively. Secreted alkaline phosphatase (SEAP) expression vectors including deletion mutants of the prothrombin gene promoter were constructed for reporter gene assay. The transcription factors bound to DNA fragments were analyzed by mass spectrometry. An electrophoretic mobility shift assay (EMSA) was performed using a biotin end-labeled DNA. The prothrombin mRNA levels in all 5 DCP producing cell lines were appreciably high. However, those in 2 DCP non-producing cell lines were below detectable levels. A SEAP vector with -2985 to +27 showed a very high transcription activity in DCP-producing Huh-1 cells. However, transcription abruptly decreased when the vector with -2955 to +27 was transfected, and then remained at the similar levels with larger deletion mutants, indicating the existence of a cis-element at -2985 to -2955 (31-bp). Mass spectrometry analysis identified the protein that bound to the 31-bp DNA as poly-(ADP-ribose) polymerase-1 (PARP-1). Knockdown of the PARP-1 gene by small interfering RNA in Huh-1 cells induced marked inhibition of prothrombin gene transcription. The EMSA clearly showed that PARP-1 specifically binds to the 31-bp DNA fragment in the prothrombin gene promoter. Our data suggest that PARP-1 activates prothrombin gene transcription and that the excessive prothrombin gene transcription induces DCP production in DCP-producing HCC cells.

(Summary) A recent increase in the rate of obesity as a result of insufficient physical exercise and excess food consumption has been seen in both developed and developing countries throughout the world. Additionally, the recent increased number of obese individuals with lifestyle-related diseases associated with abnormalities in glucose metabolism, dyslipidemia, and hypertension, defined as metabolic syndrome (MS), has been problematic. Although MS has been highlighted as a risk factor for ischemic heart disease and arteriosclerotic diseases, it was also recently shown to be associated with digestive system disorders, including upper gastrointestinal diseases. Unlike high body weight and high body mass index, abdominal obesity with visceral fat accumulation is implicated in the onset of various digestive system diseases because excessive visceral fat accumulation may cause an increase in intra-abdominal pressure, inducing the release of various bioactive substances, known as adipocytokines, including tumor necrosis factor-α, interleukin-6, resistin, leptin, and adiponectin. This review article focuses on upper gastrointestinal disorders and their association with MS, including obesity, visceral fat accumulation, and the major upper gastrointestinal diseases.

(Summary) Although heavy drinking is known to lead to liver injury, some recent studies have reported that light alcohol consumption (LAC) may play a protective role against fatty liver in the general population, and may even play a protective role against non-alcoholic fatty liver disease (NAFLD) in males with metabolic syndrome (MS). However, the association between LAC and fatty liver with liver enzyme elevation in females with MS is unclear. Participants of this study were 20,853 females who underwent a regular health check-up between April 2008 and March 2012 at our hospital. Enrolled subjects were 1141 females with MS, who underwent all necessary tests and drank less than 20 g/day of alcohol. We investigated the presence of fatty liver with liver enzyme elevation, defined in this study as alanine aminotransferase (ALT) levels ≧31 IU/I, and the association between LAC and fatty liver with ALT elevation. There was no significant difference in the prevalence of fatty liver and ALT between light drinkers and non-drinkers. The prevalence of individuals receiving a treatment for dyslipidemia and impaired glucose tolerance (IGT) was significantly lower in light drinkers than in non-drinkers. Body mass index (BMI), waist circumference (WC), diastolic blood pressure (DBP), triglyceride (TG), uric acid (UA), IGT, and visceral fat type MS (V-type MS) were significant predictors of the prevalence of fatty liver with ALT elevation in logistic regression analysis. The odds ratio [OR] (95 % confidence interval [CI], p value) for fatty liver with ALT elevation were as follows: BMI, 2.181 (1.445-3.293, p <0.001); WC, 1.853 (1.280-2.684, p <0.01); DBP, 1.604 (1.120-2.298, p <0.05); TG, 2.202 (1.562-3.105, p <0.001); UA, 2.959 (1.537-5.698, p <0.01); IGT, 1.692 (1.143-2.506, p <0.01); and V-type MS, 3.708 (2.529-5.437, p <0.001). There was no significant difference in the prevalence of fatty liver with ALT elevation in females with MS between light drinkers and non-drinkers, suggesting that other factors such as BMI, WC, V-type MS, and lifestyle-related disease may be more important than LAC for the prevalence of fatty liver with ALT elevation.

(Summary) Objective evaluation of intestinal mucosal damage due to anticancer drugs is generally difficult. Serum diamine oxidase (DAO) activity is reported to reflect the integrity and maturity of the small intestinal mucosa. Therefore, we investigated whether serum DAO activity is an indicator of gastrointestinal toxicity or nutritional status in patients receiving chemotherapy. We prospectively enrolled 20 patients with unresectable metastatic gastric cancer who received oral S-1 (80 mg/m(2) ) on days 1-14, and intravenous cisplatin (60 mg/m(2) ) and docetaxel (50 mg/m(2) ) on day 8 every 3 weeks. Serum DAO activity was measured by colorimetry. Gastrointestinal toxicity was evaluated by CTCAE v4.0. Endoscopic examination and biopsy of duodenal mucosa assessed mucosal damage. Malnutrition was evaluated by measuring serum total protein and albumin levels. Serum DAO activity decreased step-by-step significantly during anticancer drug treatment and recovered after drug holidays. In all 14 patients who experienced diarrhea, serum DAO activity significantly decreased prior to diarrhea onset. Percent decrease in DAO activity was significantly correlated with severity of diarrhea. Significant correlation was observed between percent decrease in DAO activity and percent decrease in duodenal villus height or surface area from baseline. There were also significant correlations between percent decrease in serum DAO activity at day 14 and percent decrease in serum total protein or albumin levels at day 21 from baseline. Serum DAO activity sensitively indicates gastrointestinal damage prior to symptom onset and can be a useful predictor of intestinal mucosal damage and nutritional status in patients receiving chemotherapy.

(Summary) This study was conducted to identify the maximum-tolerated dose (MTD) of fixed-dose-rate gemcitabine (FDR-gem) administered concurrently with S-1 and radical radiation for locally advanced pancreatic cancer (LAPC) and to provide efficacy and safety data. Patients with unrespectable pancreatic cancer confined to the pancreatic region were treated with FDR-gem (300-400 mg/m(2), 5 mg/m(2)/min) on days 1, 8, 22, and 29 and 60 mg/m(2) of S-1 orally on days 1-14, 22-35. A total radiation dose of 50.4 Gy (1.8 Gy/day, 28 fractions) was delivered concurrently. Twenty-five patients were enrolled; all were evaluable for toxicity assessment. In phase I, eight patients were treated in sequential cohorts of three to five patients per dose level. The MTD was reached at level 2, and dose-limiting toxicities were neutropenia and thrombocytopenia. The recommended doses were 300 mg/m(2) of gemcitabine and 60 mg/m(2) of S-1 daily. The overall response rate was 25% and disease control rate (partial response plus stable disease) was 92%. The progression-free survival was 11.0 months. The median overall survival and 1-year survival rates were 16.0 months and 73%, respectively. The combination of FDR-gem and S-1 with radiation is a feasible regimen that shows favorable antitumor activity with an acceptable safety profile in patients with LAPC.

(Summary) Antiplatelet drugs are widely used for the prevention of cardiovascular disease and cerebral vascular disorders. Although there have been several studies on gastroduodenal mucosal injury with gastrointestinal (GI) symptoms such as GI bleeding, in antiplatelet drug users (including low-dose aspirin (LDA)), there have been few reports on the association between antiplatelet drug use and gastroduodenal mucosal injury in asymptomatic antiplatelet drug users. This study was a cross-sectional study elucidating the association between antiplatelet drug use and gastroduodenal mucosal injury in asymptomatic antiplatelet drug users.Subjects were 186 asymptomatic Japanese antiplatelet drug users who underwent a regular health checkup. Subjects were divided into those with and without gastroduodenal mucosal injury endoscopically, and the association between gastroduodenal mucosal injury and other data in asymptomatic antiplatelet drug users was investigated.The prevalence of males and drinkers were significantly higher in subjects with gastroduodenal mucosal injury than in those without. In addition, the prevalence of proton pump inhibitor (PPI) users was significantly lower in subjects with gastroduodenal mucosal injury than in subjects without gastroduodenal mucosal injury. Logistic regression analysis showed PPI (odds ratios: 0.116; 95% confidence intervals: 0.021-0.638; P < 0.05) was a significant predictor of a decreased prevalence of gastroduodenal mucosal injury and closed-type (C-type) atrophy (3.172; 1.322-7.609; P < 0.01) was a significant predictor of an increased prevalence of severe gastroduodenal mucosal injury in asymptomatic antiplatelet drug users.Gender and lifestyle, such as drinking, may have an impact on risk of gastroduodenal mucosal injury in asymptomatic subjects taking antiplatelet drugs. Although PPI is a significant predictor of a decreased prevalence of gastroduodenal mucosal injury, including in asymptomatic antiplatelet drug users, status of gastric atrophy should also be considered against severe gastroduodenal mucosal injury.

(Summary) Although excess alcohol consumption has been believed to cause liver injury, light alcohol consumption (LAC) has been reported to play a protective role against fatty liver in recent studies. However, the association between non-alcoholic fatty liver disease (NAFLD) and LAC in men with metabolic syndrome (MS) is unclear. The aim of this study was to examine the association between NAFLD and LAC in men with MS. Subjects were 1055 men with MS who underwent a regular health check-up and drank less 20 g/day of alcohol. A distinction was made between non-drinkers and light drinkers and the association between NAFLD and LAC in men with MS was elucidated. NAFLD was referred as fatty liver with alanine aminotransferase (ALT) levels 31 IU/L in this study. Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and the prevalence of NAFLD were significantly lower in light drinkers than in non-drinkers. Logistic regression analysis showed body mass index (BMI), waist circumference (WC), uric acid (UA), haemoglobin A1c (HbA1c), visceral fat type MS and LAC (odds ratios: 0.654; 95% confidence intervals: 0.473-0.906; <0.05) were significant predictors of the prevalence of NAFLD. The prevalence of NAFLD in light drinkers was significantly lower than in non-drinkers, and supporting previous reports studying the general population, LAC is one of the significant predictors of a decreased prevalence of NAFLD in men with MS.

(Summary) Sessile serrated adenomas/polyps (SSA/Ps) are a putative precursor of colon cancer with microsatellite instability (MSI). However, the developmental mechanism of SSA/P remains unknown. We performed genetic analysis and genome-wide DNA methylation analysis in aberrant crypt foci (ACF), SSA/P, and cancer in SSA/P specimens to show a close association between ACF and the SSA/P-cancer sequence. We also evaluated the prevalence and number of ACF in SSA/P patients. ACF in the right-side colon were observed in 36 patients with SSA/Ps alone, 2 with cancers in SSA/P, and 20 normal subjects and biopsied under magnifying endoscopy. B-RAF mutation and MSI were analysed by PCR-restriction fragment length polymorphism (RFLP) and PCR-SSCP, respectively, in 15 ACF, 20 SSA/P, and 2 cancer specimens. DNA methylation array analysis of seven ACF, seven SSA/P, and two cancer in SSA/P specimens was performed using the microarray-based integrated analysis of methylation by isochizomers (MIAMI) method. B-RAF mutations were frequently detected in ACF, SSA/P, and cancer in SSA/P tissues. The number of methylated genes increased significantly in the order of ACF<SSA/P<cancer. The most commonly methylated genes in SSA/P were PQLC1, HDHD3, RASL10B, FLI1, GJA3, and SLC26A2. Some of these genes were methylated in ACF, whereas all genes were methylated in cancers. Immunohistochemistry revealed their silenced expression. Microsatellite instability and MLH1 methylation were observed only in cancer. The prevalence and number of ACF were significantly higher in SSA/P patients than in normal subjects. A significant correlation was seen between the numbers of SSA/P and ACF in SSA/P patients. Our results suggest that ACF are precursor lesions of the SSA/P-cancer sequence in patients with SSA/P, where ACF arise by B-RAF mutation and methylation of some of the six identified genes and develop into SSA/Ps through accumulated methylation of these genes.

(Summary) Obesity and metabolic syndrome (MS) are strongly associated with erosive esophagitis (EE). The prevalence of MS and EE, and the distribution of adipose tissue have been known to differ markedly between men and women. Although the prevalence of EE in men with MS is known to be higher in visceral fat type MS (V-type MS) than in subcutaneous fat type MS (S-type MS), the association between EE and the types of MS in women with MS is unclear. This study was a cross-sectional study elucidating the association between EE and the types of MS in women with MS. Subjects were 454 women with MS who underwent a regular health check-up. A distinction was made between V-type MS and S-type MS and the prevalence of EE and the association between EE and other data were elucidated. Although there were some significant different factors in characteristics between V-type MS and S-type MS, there was no significant difference in the prevalence of EE between V-type MS and S-type MS. The presence of Helicobacter pylori (H. pylori) was significantly lower than in subjects with EE (13.7%) than in subjects without EE (41.9%). The frequency of hiatal hernia was significantly higher in subjects with EE (60.8%) than in subjects without EE (24.6%). Logistic regression analysis showed hiatal hernia (odds ratio: 4.673; 95% confidence interval: 2.448-8.920; P<0.001), hemoglobin A1c (HbA1c) (2.325; 1.110-4.870; P<0.05), and the presence of H. pylori (0.239; 0.101-0.567; P<0.005) were significant predictors of the prevalence of EE. V-type MS may not be such an important factor for the prevalence of EE in women with MS as in men with MS. The absence of H. pylori, hiatal hernia, and HbA1c may be more important for the prevalence of EE than the types of MS in women with MS.

(Summary) The antitumor activity of pladienolide B, a novel splicing inhibitor, against gastric cancer is totally unknown and no predictive biomarker of pladienolide B efficacy has been reported. We investigated the antitumor activity of pladienolide B and its derivative on gastric cancer cell lines and primary cultured cancer cells from carcinomatous ascites of gastric cancer patients. The effect of pladienolide B and its derivative on six gastric cancer cell lines was investigated using a MTT assay and the mean IC50 values determined to be 1.6 ± 1.2 (range, 0.6-4.0) and 1.2 ± 1.1 (range, 0.4-3.4) nM, respectively, suggesting strong antitumor activity against gastric cancer. The mean IC50 value of pladienolide B derivative against primary cultured cells from 12 gastric cancer patients was 4.9 ± 4.7 nM, indicative of high antitumor activity. When 18 SCID mice xenografted with primary cultured cells from three patients were administered the pladienolide B derivative intraperitoneally, all tumors completely disappeared within 2 weeks after treatment. Histological examination revealed a pathological complete response for all tumors. In the xenograft tumors after treatment with pladienolide B derivative, immature mRNA were detected and apoptotic cells were observed. When the expressions of cell-cycle proteins p16 and cyclin E in biopsied gastric cancer specimens were examined using immunohisctochemistry, positivities for p16 and cyclin E were significantly and marginally higher, respectively, in the low-IC50 group compared with the high-IC50 group, suggesting the possibility that they might be useful as predictive biomarkers for pladienolide B. In conclusion, pladienolide B was very active against gastric cancer via a mechanism involving splicing impairment and apoptosis induction.

(Summary) During the last decade, researchers have made great progress in the development of new image processing technologies for gastrointestinal endoscopy. However, diagnosis using conventional endoscopy with white light optical imaging is essentially limited, and ultimately, we still rely on the histopathological diagnosis from biopsy specimens. Molecular imaging represents the most novel imaging methods in medicine, and the future of endoscopic diagnosis is likely to be impacted by a combination of biomarkers and technology. Endoscopic molecular imaging can be defined as the visualization of molecular characteristics with endoscopy. These innovations will allow us not only to locate a tumor or dysplastic lesion but also to visualize its molecular characteristics and the activity of specific molecules and biological processes that affect tumor behavior and/or its response to therapy. In the near future, these promising technologies will play a central role in endoluminal oncology.

(Summary) In this study we propose a novel simple automatic method to detect the bowel sound(BS)s based on the 3 dB bandwidth of the frequency peaks in the autoregressive moving average spectrum. We use the measure, sound-to-sound interval (SSI) obtained by the proposed method, to capture bowel motility. In this paper, we show that the proposed method for automatic detection could achieve a sensitivity of 87.8±5.88%, specificity of 91.7±4.33% and area under the curve of 0.923 when working on 16 healthy volunteers during mosapride administrations. Furthermore, we show that the measured SSI averaged over a period of 30 min can clearly capture bowel motility. Our findings should have the potential to contribute toward developing automated BS-based diagnosis of IBS.

(Summary) Endoscopic submucosal dissection (ESD) in early gastric cancer has rapidly come into widespread use. However, since complications such as bleeding and perforation often occur, and the procedure time is longer for ESD than endoscopic mucosal resection (EMR), development of safer and more reliable technique is required. The subjects comprised 45 patients with lesions diagnosed histologically as early gastric cancer. They were divided into three groups: cross-counter technique group (CC, n = 15), peroral traction-assisted ESD with suture material group (PT, n = 15), and no-traction group (NT, n = 15). ESD was carried out by two endoscopists who had experienced fewer than 30 cases of ESD. To compare safety and efficacy of a new traction method (CC group) for ESD in early gastric cancer with other methods (PT group and NT group), procedure time, dissected area per unit time, complete resection rate, perforation rate, and bleeding rate were evaluated. There was no significant difference among these three groups in terms of complications, complete resection rate or procedure time. The dissection area per unit time was 22.4, 15.7, and 13.5 mm(2)/min in the CC, PT, and NT groups, respectively, and there was a significant difference between the CC and NT groups (p = 0.007). The cross-counter technique shortened the treatment time for endoscopists without abundant experience in gastric ESD, and it is considered a useful method to institute in order to introduce ESD.

(Summary) We compared high-sensitivity KRAS mutation testing with direct sequencing for predicting the efficacy of antiepidermal growth factor receptor antibodies in patients with metastatic colorectal cancer (mCRC). We analyzed the KRAS status in 61 tumors from cetuximab-treated mCRC patients by both direct sequencing and a high-sensitivity method: 2-step PCR restriction fragmentation length polymorphism (RFLP). Therapeutic effects in each mutational status were evaluated. The incidences of KRAS mutations determined by direct sequencing and 2-step PCR RFLP were 34.4 and 52.5%, respectively (p = 0.02). Patients were categorized into 3 groups [W/W, wild-type by both methods (n = 29); W/M, wild-type by direct sequencing, detected mutation by 2-step PCR RFLP (n = 11); M/M, mutant-type by both methods (n = 21)]. The response rate for cetuximab in the W/M group (0%) was the same as that in the M/M group, and was significantly lower than in the W/W group (41.4%) (p < 0.001). Progression-free survival in the W/M group (11.0 weeks) was similar to that in the M/M group (8.0 weeks), and was significantly shorter than in the W/W group (18.0 weeks) (p < 0.002). High-sensitivity KRAS mutation testing is useful for selecting true responders to cetuximab.

(Summary) Radiation proctitis is an increasingly prevalent problem, with many patients being treated with radiotherapy for pelvic cancers. However, the mechanisms by which radiation proctitis develops in humans are not well understood. In this study, the expression profiles of angiogenic factors were analyzed to clarify their role in the etiology of radiation proctitis. Rectal biopsies were taken from 8 patients with radiation proctitis and 8 normal subjects. Protein lysates of the tissues were applied to an antibody array for angiogenesis-related factors. The mRNA level of each factor was evaluated by Taqman real-time PCR. Immunohistochemistry was performed using the labeled streptavidin biotin method. Antibody array analysis revealed 2.12- to 7.31-fold higher expression levels of angiogenin, fibroblast growth factor 1 (FGF1), endoglin, matrix metalloproteinase (MMP)-8, urokinase-type plasminogen activator (uPA) and maspin in radiation proctitis tissues compared with normal rectal mucosa. The mRNA level of each factor in radiation proctitis tissue was significantly higher than in normal rectal mucosa, suggesting their transcriptional activation. Immunohistochemical staining showed strong expression of angiogenin and maspin in rectal epithelia, MMP-8 and uPA in infiltrating lymphocytes, FGF1 in fibroblasts and endoglin in endothelial cells. The expression of VEGF was not evident. Our results suggest that in radiation proctitis, MMP-8 and uPA cooperatively degrade the extracellular matrix and basement membrane to provide space for angiogenesis. Simultaneously, angiogenin and FGF1 promote endothelial cell proliferation, and endoglin induces vessel formation, culminating in angiogenesis. Inhibitors of angiogenic factors such as angiogenin and FGF1 may be effective for treating radiation proctitis.

(Summary) In Japan, endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) have been widely accepted and standardized for the treatment of gastrointestinal superficial neoplasia. In contrast, mucosal ablation techniques are more common in Western countries and a variety of endoscopic ablation modalities, including argon plasma coagulation (APC), photodynamic therapy (PDT) and lasers, are used. Recently developed modalities such as radiofrequency ablation (RFA) and cryotherapy are also available for the treatment of superficial lesions such as dysplasia of Barrett's esophagus. Although we should understand that the completeness of destruction of neoplastic tissue can only be judged at follow up, endoscopic ablation is a viable alternative to endoscopic resection for dysplasia and early-stage malignancies, especially for poor candidates of surgery or endoscopic resection.

(Summary) Diabetic patients with poor glycemic control or long standing disease often have impaired gastric motility. Recently, metabolic factors such as blood glucose have been reported as influencing gastric motility independently of autonomic neuropathy. Many diabetic patients have metabolic syndrome, which is strongly associated with coronary and other diseases. We investigated whether metabolic syndrome influences diabetic gastroparesis patients. We observed gastric motility ultrasonographically in diabetic gastroparesis patients including nine with and nine without metabolic syndrome. Both groups complained of upper abdominal symptoms when hospitalized to improve blood sugar control. All patients underwent upper gastrointestinal endoscopy to rule out gastric and duodenal lesions. All had autonomic neuropathy. Gastric motility was evaluated within 3 days after admission by transabdominal ultrasonography after a test meal. Gastric emptying was 45.0 +/- 13.7% in patients with and 39.1 +/- 11.9% in patients without metabolic syndrome, which was not statistically significant. Frequency of gastric contractions was 8.33 +/- 2.78 per 3 min in patients with metabolic syndrome and 7.44 +/- 2.13 per 3 min in the others, which was not statistically significant. The motility index, which involves antral contractility, was 3.21 +/- 2.18 in patients with metabolic syndrome and 2.80 +/- 1.87 in the others, which was not statistically significant. Metabolic syndrome did not appear to contribute to delayed gastric motility in diabetic gastroparesis.

(Summary) Continuous monitoring of hematocrit with a CRIT-LINE monitor (CLM) is used to prevent excess ultrafiltration during hemodialysis and continuous renal replacement therapy. The presence of substances affecting the scattering and absorption rates of multiple wavelengths of near infrared rays of CLM in the blood may affect the measured values with CLM. We examined the influences of lipid emulsion (LE) on hematocrit and relative blood volume (RBV) which were measured with CLM using an in vitro experimental model with human blood. Additions of 10% or 20% of LE increased the hematocrit measured by LCM and decreased the percent change of RBV in proportion to the dose. One percentage of 20% LE in the plasma increased the expected hematocrit measured with CLM by 2.9%. The decrease of initial hematocrit from 48.1% to 43.4% decreased the expected percent change of RBV from -3.4% to -3.7% with the addition of 1 ml of 20% LE to 100 ml blood. These findings indicate that additions of LE increase hematocrit that is measured with CLM in proportion to the dose of LE. Low levels of initial hematocrit will increase the degree of expected percent change of RBV. Attention should be paid to the influence of LE during monitoring with CLM.

(Summary) Continuous hemodiafiltration (CHDF) has been performed for the treatment of severe acute pancreatitis. Phospholipase A2 (PLA2) is one of the important mediators which exacerbate acute pancreatitis, but whether PLA2 can be removed by CHDF is unclear. In this study, the kinetics of group IB and group IIA PLA2 was examined at the first session of low-volume CHDF in eight patients with severe acute pancreatitis. CHDF was performed using polysulfone hemofilters (surface area: 0.7 m(2)) at a blood flow rate of 100 mL/min and a filtration and dialysate flow rate of 10 mL/min each. The plasma concentrations of group IB and IIA PLA2 before the start of CHDF were 47.4 +/- 52.0 microg/L and 352 +/- 390 microg/L, respectively, and did not change significantly. The clearances of group IB and IIA PLA2 achieved by the CHDF circuit 1 h after the start of CHDF were 20.7 +/- 11.6 mL/min and 16.7 +/- 4.4 mL/min, respectively, with both clearances decreasing significantly with time. The clearance of group IB PLA2 into the waste fluid tended to increase with time; however, the concentrations of group IIA PLA2 in the waste fluid were less than the measurable sensitivity. These results indicate that group IB PLA2 is adsorbed on the hemofilter membrane in preference to being removed into the waste fluid, while group IIA PLA2 is mainly removed by adsorption. However, low-volume CHDF is not effective at eliminating the group IB and IIA PLA2 plasma concentration.

(Summary) Continuous hemodiafiltration (CHDF) has recently been used for treatment of severe acute pancreatitis. CHDF is capable of eliminating small molecules from blood, but whether trypsin can be eliminated by CHDF is not clear. In this study, elimination of trypsin-like enzyme activity (TLE) and cationic trypsin-like immunoreactivity (TLI) using low-volume CHDF was examined at the first CHDF session in eight patients with severe acute pancreatitis. CHDF was performed with a polysulfone hemofilter (membrane area, 0.7 m2) and nafamostat mesilate, a protease inhibitor and anticoagulant, at a blood flow rate of 100 ml/min and a filtration and dialysis flow rate of 10 ml/min each. Before beginning CHDF, plasma TLE was 3.41 +/- 2.86 nmol/(ml.min), and TLI was 5,900 +/- 9,008 ng/ml. The average plasma clearances of TLE and TLI achieved by the circuit during the 12-hour therapy were 56.7 +/- 4.9 ml/min and 8.0 +/- 7.2 ml/min, respectively. The average plasma clearance of TLI into the waste fluid was 2.4 +/- 1.6 ml/min whereas TLE was below the measurable sensitivity. The plasma concentration of TLE and TLI remained unchanged. These results indicate that low-volume CHDF using nafamostat mesilate as an anticoagulant can increase trypsin plasma clearance. However, low-volume CHDF is not effective to eliminate the plasma trypsin concentration.

(Summary) In Japan, leukocytapheresis (LCAP) therapy has been carried out for ulcerative colitis as an effective therapy with a low incidence of side-effects. In the present study, we serially investigated the influence of LCAP therapy on anemia and hemodynamics in patients with ulcerative colitis using a non-invasive method with a Crit-Line monitor (CLM) (Hema Metrics Inc., Salt Lake City, UT and Boston, MA, USA). We carried out LCAP on 10 patients with ulcerative colitis using a CS-100 Cellsorba EX LCAP filter in 34 courses of LCAP. The mean hematocrit value, which was measured using the Crit-Line monitor, was 21.8 +/- 0.2% (21.0-22.4%), which showed no significant changes after each LCAP therapy. The actual erythrocyte count, hemoglobin and hematocrit values decreased by 244 000/mm3, 0.7 g/dL and 2.1%, respectively, however, the differences were insignificant. These values corresponded to 7.8, 8.0 and 7.6% of the values before LCAP, respectively. There were no significant changes in systolic blood pressure, diastolic blood pressure, or heart rate during LCAP. The results of this study suggest that one course of LCAP does not exacerbate anemia, and it does not influence hemodynamics. However, considering the exacerbation of anemia in patients with severe ulcerative colitis caused by massive melena, monitoring with a less invasive Crit-Line monitor and a vital information monitor might be useful.

(Summary) Since 1995, the Baylor Group has been developing a totally implantable NEDO BVAD system. This 10-year program was completed in March 2005, and preparation for clinical trials is underway. This article summarizes the entire 10-year NEDO program and describes the strategy for clinical trials. The project aimed to achieve: (1) dual centrifugal pumps with the ability of full biventricular support, (2) a compact system implantable into small adults, (3) a totally implantable system with transcutaneous energy transmission system (TETS), (4) a durable system with a lifetime of over 5 years, and (5) a system free of thrombus and with minimal hemolysis. The final goals are to complete preclinical system evaluations and commence the clinical trials in the near future. In vitro studies have demonstrated a pump capacity of over 8.5 l/min and an Index of Hemolysis of <0.004 g/100 l. The pump-bearing life expectancy was over 5 years. To date, eight pumps endured in vivo studies of over 3 months without complications, including thromboembolic events. The in vitro endurance studies of eight pumps are longer than 1 year. There were no mechanical malfunctions or pump failure. A stepwise clinical trial is being planned: Step1, a wearable BVAD/VAD will be clinically studied; Step 2, the BVAD/VAD will be implanted intracorporeally without TETS; and, Step 3, a totally implantable system will be clinically evaluated. The NEDO BVAD system has completed preclinical testing. Clinical trial preparation is underway.

(Summary) In totally implantable ventricular assist device systems, measuring flow rate of the pump is necessary to ensure proper operation of the pump in response to the recipient's condition or pump malfunction. To avoid problems associated with the use of flow probes, several methods for estimating flow rate of a rotary blood pump used as a ventricular assist device have been studied. In the present study, we have performed a chronic animal experiment with two NEDO PI gyro pumps as the biventricular assist device for 63 days to evaluate our estimation method by comparing the estimated flow rate with the measured one every 2 days. Up to 15 days after identification of the parameters, our estimations were accurate. Errors increased during postoperation days 20 to 30. Meanwhile, their correlation coefficient r was higher than 0.9 in all the acquired data, and estimated flow rate could simulate the profile of the measured one.

(Summary) A clipped single-bag for bicarbonate replacement fluid was developed to ensure proper mixing before administering to the patient. Nonmixture can cause imbalances of electrolytes and pH, which is a key problem for the current double-bag type bicarbonate replacement fluid sets. To resolve this problem, this single bag properly mixes the solutions before use. The new bag consists of a clip that is placed in the middle to keep the two solutions separated and sealed. When the caregiver is ready to administer treatment, the bag is simply unfolded and the clip automatically detaches, releasing the fluids. Thereby, the bicarbonate fluids are effectively mixed. An optimal clip size with an outer diameter of 16 mm and thickness of 2 mm was determined using compression tests and drop tests. This bag may be a safer and more effective way to provide proper replacement fluid supply for both hemofiltration and hemodiafiltration.

(Summary) Little attention has been paid to colorectal xanthoma. To clarify the clinical and pathological features of colorectal xanthoma, we report 28 colorectal xanthomas biopsied from 25 patients. All were composed of typical xanthoma cells and showed polypoid configuration. Median age of the patients was 64 years and there were 15 men and 10 women. Diabetes mellitus, constipation, and hyperlipidemia were found in two, one, and seven patients, respectively. Seventeen (60.7%) of the 28 polyps were located in the sigmoid colon and the remaining 11 in the rectum. Twenty-three polyps (82.1%) were sessile. Twelve (60.0%) of twenty polyps that were recorded were reddish in color. Only two polyps revealed a yellowish tone. Microscopically, foamy cells were present in the lamina propria, but the submucosa did not contain foamy cells. Immunohistochemically, the foamy cells invariably expressed extensive positivity for CD68. The colonic glands showed a deformity in the case with moderate to intense density of the foamy cells. The surface epithelium showed a hyperplastic change in 22 (78.6%) xanthomas. The colonic glands in four xanthomas were also associated with hyperplastic changes. The basement membrane of the surface epithelium was often thickened. Cell debris and proliferation of the capillaries were observed just below the surface epithelium in 19 (67.9%) and 22 (78.6%) xanthomas, respectively. Previous mucosal minute injury was suggested as the pathogenesis of colorectal xanthomas. Colorectal xanthomas were not identical to gastric and esophageal xanthoma, endoscopically or microscopically. We prefer the term "xanthomatous polyp" rather than xanthoma in the colorectal region. They may be regarded as a novel type of colorectal non-neoplastic polyp.

(Summary) The study examines the clinical significance of guanase (GU) measurement in patients with hepatitis C. 688 patients in whom either ALT was abnormal, or in whom HBsAg or HCVAb was detected in the serum, were enrolled into this study. The percentage of cases in which normal ALT while elevated GU was compared among the different disease groups. Then, the percentage of cases with normal ALT but elevated GU was compared between HBV and HCV groups. For the entire population, a significant correlation was observed between ALT and GU (r=0.872). The overall percentage of cases with normal ALT but elevated GU activity was 11.4%. In HCV group, 449 cases had normal ALT. Of these cases, 20.3% had elevated GU, while ALT was normal. Before 1989, no test to check donated blood for HCV antibody was available. However, screening of donated blood for high GU was associated with a reduced incidence of post-transfusion hepatitis. This is probably because following the screening, blood donated by patients with hepatitis C who had normal ALT but elevated GU was rejected. After the introduction of HCV antibody measurement, GU measurement is still useful to reveal the pathophysiological condition in-patients with chronic hepatitis type C.

(Summary) Bleeding due to esophageal variceal rupture is associated with an extremely high mortality rate. Variceal bleeding is frequent in patients who have a red color sign on endoscopy. However, the red color sign is subjectively evaluated on the basis of color tone and the shape of the varices. To allow standardization and facilitate consensus, an objective method of assessing the red color sign is needed. In this study, a system was established for quantifying the red color sign during endoscopic evaluation. Between July 1995 and February 1997, 55 untreated patients with portal hypertension and esophageal varices identified on upper gastrointestinal endoscopy were enrolled in the study. Images obtained about 5 cm oral to the esophagogastric junction during endoscopy were stored on magnetic optical disks using an endoscopic image processor. The still images were transmitted to a computer and analyzed using computer software. The RGB components (R, red; G, green; B, blue) were measured at points showing flare consistent with the red color sign. The endoscopic assessment was based on the Japanese Research Society for Portal Hypertension's general rules for recording endoscopic findings in esophagogastric varices. The ratio of the red color area to the variceal area increased with increasing red color grade. There were significant positive correlations between the R and G, and G and B components. This suggests that comparing the R components alone would allow assessment of the color differences in the red color area and in the varices. The R value was significantly higher in the red color area (115 +/- 20) than in the varices (57 +/- 19). An R value of 90 was found at the boundary between the two parts (P < 0.001). The red color area can be automatically calculated and quantified using the analysis program. Improvements in data storage methods may allow real-time evaluation during endoscopy in the future.

(Summary) We examined the effects of the autonomic nervous function and the volume of portal blood flow to clarify the mechanism of the abnormal gastric motility in patients with liver cirrhosis. Heart rate variability, electrogastrogram (EGG), and volume of portal blood flow were measured before and after a meal in 27 patients with liver cirrhosis (LC group) and in 20 normal subjects (N group). Autonomic nervous function was evaluated by using spectral analysis of heart rate variability. We used the cine phase-contrast (PC) method, using magnetic resonance imaging (MRI) to measure the portal flow, while the peak frequency and spectral power of the EGG were measured at pre- and postprandial change. The ratio of low frequency power to high frequency power (LF/HF) was significantly higher, and the HF power was significantly lower in the LC group than in the N group both before and after a meal. In both groups, the electrogastrographic peak power ratio before and after a meal showed a positive correlation with the HF ratio, and an inverse correlation with the LF/HF ratio. In addition, portal blood flow volume was significantly decreased in the LC group than in the N group. However, the increased rate of portal blood flow after a meal correlated positively with the increased rate of electrogastrographic peak power. Moreover, gastric motility was positively correlated with esophageal varices and coma scale with the use of multivariate analysis. Parasympathetic hypofunction, sympathetic hyperfunction and portal hemodynamics were closely related with gastric motility in cirrhotic patients. In addition, gastric motility was decreased, at least in part, by the ingestion of food in cirrhotic patients because of abnormalities in autonomic functions and portal blood flow following a meal.

(Summary) The relationship between 1/f fluctuation of the heart rate variability and Helicobacter pylori infection was evaluated, in order to clarify whether autonomic nervous dysfunction is a necessary condition for chronic peptic ulcer formation. The subjects were 11 patients with recurrent chronic peptic ulcer and 20 age-matched normal subjects. Holter ECGs were recorded over 24 h, and the 1/f(-x) fluctuation of the heart rate was computed. The 1/f(-x) fluctuation of the heart rate is a novel index of autonomic function that has been shown to reflect a patient's pleasant mood. For 1/f(-x) fluctuation, the slope of the regression line (-x) was determined and cosine fitting of the absolute slope of the regression line over a 24-h period was performed. For the normal group, the absolute slope of the regression line during daytime and night-time were 0.53 +/- 0.16 and 1.05 +/- 0.18, respectively. For the peptic ulcer group, the corresponding values during daytime and night-time were 0.94 +/- 0.15 and 1.84 +/- 0.18, respectively. The mean value of the cosine curve was 0.76 +/- 0.23 in the normal group and 1.12 +/- 0.25 in the peptic ulcer group. Thus, these values were significantly higher for the latter group than for the former group (P<0.05). No statistically significant difference in H. pylori infection between the two groups was observed. Autonomic nervous dysfunction as well as H. pylori infection appears to be a necessary condition for chronic peptic ulcer formation.

(Summary) Xanthogranulomatous cholecystitis (XGC) is an unusual inflammatory disease of the gallbladder that may simulate gallbladder cancer. We report the findings with conventional sonography, endoscopic sonography (EUS), and CT in 3 cases of XGC. EUS could visualize hyperechoic nodules in the gallbladder wall, probably representing xanthogranulomas, but loss of the multilayered structure of the gallbladder wall and infiltration into adjacent organs make differentiating XGC from gallbladder cancer difficult with EUS alone.

(Summary) To determine the utility and limitations of an ultrasonic miniprobe (UMP) in the staging of gastric cancer, we evaluated 46 patients who underwent endoscopic ultrasonography (EUS) using an UMP and who were histologically determined to have gastric cancers. In every case, UMP findings were compared with histopathological findings after treatment. The total accuracy of UMP relative to the depth of tumor invasion was 71.7% (33/46 cases). Accuracy with respect to T1-m tumor diagnosis was 75.7% (22/29 cases), and for T1-sm, 76.9% (10/13 cases), but accuracy for T2 tumor diagnosis was low, due to ultrasound attenuation. When the analysis was carried out based on the size of tumor, the accuracy for UMP was 50.0% (9/18 cases) for all tumors over 20 mm and 85.7% (24/28 cases) for all tumors smaller than 20 mm. We conclude that UMP is suitable for investigation of tumor extension when the lesion is superficial and/or small gastric cancers which do not cause ultrasonic attenuation, but not when the tumor is large or located in certain sites, although conventional EUS is useful in some of these cases.

(Summary) The contrast medium-removing effect of hemofiltration (HF) and hemodiafiltration (HDF) was experimentally investigated using a bovine blood tank model. HF and HDF were performed at a blood flow rate of 100 ml/min with a polysulfone hemofilter (PS filter-CF; membrane area: 0.7 m2). Two hundred milliliters of iomeprol (300 mgI/ml) was administered by a single injection into 4 liters of bovine blood. The blood half-lives of iomeprol were 1.0 hr for the high flow rate HDF group [replacement fluid flow rate (QF): 10 ml/min and dialysate flow rate (QD): 40 ml/min], 1.8 hr for the HDF group (QF: 10 ml/min and QD: 10 ml/min), and 3.8 hr for the HF group (QF: 10 ml/min). The mean clearance rates were 39.7 ml/min for the high flow rate HDF group, 21.4 ml/min for the HDF group, and 12.0 ml/min for the HF group. Iomeprol was mostly excreted in the waste fluid. It is concluded that HDF can remove contrast media more effectively than HF.

(Summary) The plasma bradykinin (BK) and serum amylase levels and histological changes in rats during the course of acute pancreatitis induced by a large dose of cerulein were examined. Animals were given four intraperitoneal injections of 20 micrograms/kg body wt of cerulein at hourly intervals. The plasma concentration of BK-like immunoreactivity (BK-LI), measured by a highly sensitive and specific radioimmunoassay established in this study, was found to reach a peak 6 h after the first injection of cerulein and then to remain elevated. On the other hand, the serum amylase and the histological alterations (i.e., interstitial edema, vacuolization, and inflammatory infiltration) were maximal 9 h after the first injection and returned to nearly normal after 24 h. These observations suggest that the BK generation is indicative of the participation of the kallikrein-kinin system in the pathophysiological change and that the plasma BK-LI level is a good marker of cellular damage and inflammation within the pancreas during the course of acute pancreatitis.

(Summary) Endoclip migration into the common bile duct following laparoscopic cholecystectomy (LC) is an extremely rare complication. Migrated endoclip into the common bile duct can cause obstruction, serve as a nidus for stone formation, and cause cholangitis. We report a case of cholangitis due to a migrated endoclip and consequent choledocholithiasis 6 years after LC, which was successfully treated by endoscopic extraction.

(Summary) In this study we propose a novel autoregressive moving average (ARMA)-based method to automatically detect bowel sound (BS)s, and we use the measure, BS duration (BSD), to capture gastrointestinal motor activity. The performance of the proposed method is investigated and evaluated via computer simulations. Working on healthy volunteers during mosapride administrations, we show that the proposed method for automatic detection could achieve a sensitivity of 83.4%, specificity of 93.3% and accuracy of 91.2%. Moreover, we show that the measure BSD can conveniently capture gastrointestinal motor activity.

(Summary) Glycemic control is important for maintaining gastric motility in diabetic patients, but gastric motility has not yet been studied ultrasonographically in relation to glycemic control. We made such observations before and after establishing glycemic control in diabetic patients with gastroparesis. We studied 30 diabetic patients with upper abdominal digestive symptoms who were hospitalized for correction of poor blood sugar control and who underwent upper digestive tract endoscopy to rule out structural causes such as gastric/duodenal lesions. Gastric motility was evaluated by transabdominal ultrasonography, using a test meal, before and after attainment of glycemic control (within 3 days after admission and 3 days before discharge). Also, upper abdominal digestive symptoms present on admission and at discharge were compared. After glycemic control was established, contractions of the antral region were more frequent than before the attainment of control (8.93 +/- 1.17/3 min vs 7.63 +/- 2.22/3 min, respectively; P < 0.001). Glycemic control also significantly improved gastric emptying (before glycemic control, 49.2 +/- 14.8%; after, 67.1 +/- 11.5%; P < 0.001). This was also true for the motility index, concerning antral gastric contractility (before control, 2.97 +/- 1.57; after, 3.75 +/- 1.09; P < 0.05). Upper abdominal symptom scores were also significantly lower after attainment of control than before (0.47 +/- 0.78 vs 3.17 +/- 2.00, respectively; P < 0.001). These findings suggest that attaining glycemic control improves gastric motility and attainments upper abdominal symptoms in diabetic patients with gastroparesis.

(Summary) <p>We made an extracorporeal circulation (ECC) with light emitting diode (LED) irradiation system on adult male SD rats. We used three wave lengths of each LED which main wave lengths are 365nm, 465nm, 515nm. ECC was derived to ECC with irradiation. This system is consisted of a tubing line, a roller pump and an irradiation device. Animals were divided into not-irradiated group and other groups. We took the blood tests at pre-circulation with irradiation and post-circulation with irradiation. We compared Experimental data between pre-circulation with irradiation and post- circulation with irradiation.</p> (Keyword) 体外循環血液 / T細胞リンパ種 / LED / UVA光 / 青色光 / 青緑色光 (Link to Publication Site) ● Publication site (DOI): 10.11239/jsmbe.Annual56.S171 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1390001288070721536 ● Search Scopus @ Elsevier (DOI): 10.11239/jsmbe.Annual56.S171 (DOI: 10.11239/jsmbe.Annual56.S171, CiNii: 1390001288070721536)
