Abstract
Background Acute respiratory distress syndrome (ARDS) is respiratory failure that commonly occurs in critically ill patients, and the molecular mechanisms underlying its pathogenesis and severity are poorly understood. We evaluated mRNA and miRNA in patients with ARDS and elucidated the pathogenesis of ARDS after performing mRNA and miRNA integration analysis. Methods In this single-center, prospective, observational clinical study of patients with ARDS, peripheral blood of each patient was collected within 24 hours of admission. Sequencing of mRNA and miRNA was performed using whole blood from the ARDS patients and healthy donors. Results Thirty-four ARDS patients were compared with 15 healthy donors. Compared with the healthy donors, 1233 mRNAs and 6 miRNAs were upregulated and 1580 mRNAs and 13 miRNAs were downregulated in the ARDS patients. For both mRNA and miRNA-targeted mRNA, canonical pathway analysis showed that programmed death-1 (PD-1) and programmed cell death ligand 1 (PD-L1) cancer immunotherapy pathway was most activated and the Th2 pathway was most suppressed. For mRNA, the Th1 pathway was most suppressed. miR-149-3p and several miRNAs were identified as upstream regulators. Conclusion miRNAs regulated the PD-1 and PD-L1 cancer immunotherapy pathway and Th2 pathway through miRNA interference action of mRNA. Integrated analysis of mRNAs and miRNAs showed that T cells were dysfunctional in ARDS patients.

Abstract
Protection against endothelial damage is recognized as a frontline approach to preventing the progression of cytokine release syndrome (CRS). Accumulating evidence has demonstrated that interleukin-6 (IL-6) promotes vascular endothelial damage during CRS, although the molecular mechanisms remain to be fully elucidated. Targeting IL-6 receptor signaling delays CRS progression; however, current options are limited by persistent inhibition of the immune system. Here, we show that endothelial IL-6 trans-signaling promoted vascular damage and inflammatory responses via hypoxia-inducible factor-1α (HIF1α)-induced glycolysis. Using pharmacological inhibitors targeting HIF1α activity or mice with the genetic ablation of gp130 in the endothelium, we found that inhibition of IL-6R (IL-6 receptor)-HIF1α signaling in endothelial cells protected against vascular injury caused by septic damage and provided survival benefit in a mouse model of sepsis. In addition, we developed a short half-life anti-IL-6R antibody (silent anti-IL-6R antibody) and found that it was highly effective at augmenting survival for sepsis and severe burn by strengthening the endothelial glycocalyx and reducing cytokine storm, and vascular leakage. Together, our data advance the role of endothelial IL-6 trans-signaling in the progression of CRS and indicate a potential therapeutic approach for burns and sepsis.

Abstract
Aim This study investigated whether contrast extravasation on computed tomography (CT) angiography in patients with traumatic brain injury (TBI) is associated with death or surgical procedures. Methods Patients over 18 years old, directly brought in by ambulance with an isolated head injury and confirmed to have acute intracranial hemorrhage on a CT scan upon admission between 2010 and 2020, were included. The primary outcome was mortality, and the secondary outcome was neurosurgical procedures performed from admission to discharge from the intensive care unit. Multivariable logistic regression analyses were performed to evaluate the association between these outcomes and contrast extravasation. Results The analysis included 188 patients with a median age of 65 years, 123 men (65.4%), 34 deaths (18.1%), and 91 surgeries (48.4%). Among the 66 patients with contrast extravasation, 22 (33.3%) died and 47 (71.2%) required surgery. Among the 122 patients with no contrast extravasation, 12 (9.8%) died, and 44 (36.1%) required surgery. The presence or absence of extravascular leakage was associated with death (odds ratio, 3.6 [95% CI: 1.2-12.2]) and surgery (odds ratio, 7.6 [95% CI: 2.5-22.7]). Conclusion Contrast extravasation was associated with mortality and performance of surgery in patients with an isolated head injury.

Abstract
Recent advancements in proteomics allow for the concurrent identification and quantification of multiple proteins. This study aimed to identify proteins associated with severe burn pathology and establish a clinically useful molecular pathology classification. In a retrospective observational study, blood samples were collected from severe burn patients. Proteins were measured using mass spectrometry, and prognosis-related proteins were extracted by comparing survivors and non-survivors. Enrichment and ROC analyses evaluated the extracted proteins, followed by latent class analysis. Measurements were performed on 83 burn patients. In the non-survivor group, ten proteins significantly changing on the day of injury were associated with metabolic processes and toxin responses. ROC analysis identified HBA1, TTR, and SERPINF2 with AUCs > 0.8 as predictors of 28-day mortality. Latent class analysis classified three molecular pathotypes, and plasma mass spectrometry revealed ten proteins associated with severe burn prognosis. Molecular pathotypes based on HBA1, TTR, and SERPINF2 significantly correlated with outcomes.

Abstract
Extravascular leakage on computed tomography (CT) angiography in patients with traumatic brain injury (TBI) is associated with hematoma expansion, functional prognosis, subsequent surgery, and death. Fresh frozen plasma (FFP) administration is often necessary to treat coagulation disorders associated with TBI. This study aimed to determine the relationship between the presence of extravascular leakage on contrast-enhanced head CT, fibrinogen level at admission, and FFP administration in patients with TBI. The medical records of patients with TBI ≥18 years of age referred to our hospital between January 2010 and December 2020 were examined retrospectively. Patients who underwent contrast-enhanced CT immediately after admission were selected, and the presence or absence of extravascular leakage, fibrinogen level at admission, and percentage of patients who required FFP administration within 24 h of admission were examined; 172 patients were included. Multi-variable linear regression analysis was performed to determine the effects of contrast extravasation on fibrinogen levels at admission and was adjusted for age, sex, systolic blood pressure, time from injury to admission, Marshall CT score, Glasgow Coma Scale score at admission, Injury Severity Score, and need for emergency surgery; the regression coefficient was -19.8. The effect of extravasation on FFP administration within 24 h of admission was analyzed using logistic regression while adjusting for age, systolic blood pressure, Marshall CT score, need for emergency surgery, and fibrinogen level at admission. The odds ratio of contrast extravasation was 7.08 after adjustment. Extravascular leakage is associated with fibrinogen levels at admission and FFP administration within 24 h of admission.

Abstract
Introduction Resistin is reported to form a cytokine network and cause endothelial damage. The pathogenesis of coronavirus disease 2019 (COVID-19) remains unknown, but the association between cytokine storm and endothelial damage is crucial. This study aimed to evaluate resistin in COVID-19 pathogenesis compared with sepsis. Materials and Methods First, we evaluated the association of plasma resistin levels and disease severity and clinical outcome in two large cohorts: a publicly available cohort including 306 COVID-19 patients in the United States (MGH cohort) and our original cohort including only intubated 113 patients in Japan (Osaka cohort 1). Second, to understand pathogenesis, we evaluate resistin, cytokines and endothelial cell adhesion molecules in COVID-19 compared with sepsis. Blood samples were collected from 62 ICU-treated COVID-19 patients and 38 sepsis patients on day 1 (day of ICU admission), days 2-3, days 6-8, and from 18 healthy controls (Osaka cohort 2). The plasma resistin, inflammatory cytokines (IL-6, IL-8, MCP-1 and IL-10) and endothelial cell adhesion molecules (ICAM-1 and VCAM-1) were compared between patients and control. Correlations among resistin, inflammatory cytokines and endothelial cell adhesion molecules were evaluated in COVID-19 and sepsis. Results In the MGH cohort, the day 1 resistin levels were associated with disease severity score. The non-survivors showed significantly greater resistin levels than survivors on days 1, 4 and 8. In the Osaka cohort 1, 28-day non-survivors showed significantly higher resistin levels than 28-day survivors on days 6-8. Patients with late recovery (defined as the day of weaning off mechanical ventilation >12 or death) had significantly higher resistin levels than those with early recovery on day 1 and days 6-8. In the Osaka cohort 2, plasma resistin levels were elevated in COVID-19 and sepsis patients compared to controls at all measurement points and were associated with inflammatory cytokines and endothelial cell adhesion molecules. Conclusion Resistin was elevated in COVID-19 patients and was associated with cytokines and endothelial cell adhesion molecules. Higher resistin levels were related to worse outcome.

Abstract
BACKGROUND Growth differentiation factor-15 (GDF-15) is expressed in almost all tissues of the body and is necessary for the body's defense response to stress such as inflammation. It has been reported to be associated with incidence and mortality in many diseases, including systemic inflammatory response syndromes. There are no reports on GDF-15 in burns. The purpose of this study was to investigate the trend of GDF-15 in blood in patients with severe burns and to determine its relationship with severity and mortality. METHODS This was a retrospective, observational, single-center study. The level of GDF-15 in the blood was measured and compared with clinical parameters, including prognosis. Time points for sample collection were the day of injury, 4 days after injury, and 1 week after injury. RESULTS Eighty-three patients were enrolled in the study. At all time points, GDF-15 levels in the nonsurvivor group were significantly higher than those in the survivor group. In the analysis using the ROC curve for 28-day survival, the AUC of the GDF-15 value on the day of injury was 0.798, which was higher than those of % total body surface area, burn index, and Sequential Organ Failure Assessment (SOFA) score. GDF-15 levels correlated positively with SOFA score, and the relationship became stronger along with the time course of severe burn. CONCLUSIONS In the acute phase of severe burn, GDF-15 levels were associated with mortality and SOFA scores.

Abstract
BACKGROUND In current intensive care treatment, some patients with severe burns cannot be saved due to progressive organ failure. Further investigation of the pathogenesis of severe burns is needed to improve the mortality rate. In burns, inflammatory cytokines form a network that leads to an inflammatory response. Adipocytes secrete physiologically active substances (adipokines). The roles of adipokines have not been completely clarified in burn patients. This study aimed to determine the relation between serial changes of adipokines and clinical course in severely burned patients. METHODS This was a single-center, retrospective, observational study. Patients' blood samples were collected on the day of injury and around 1 week later. Adipokines (adiponectin, angiotensinogen, chemerin, CXCL-12/SDF-1, leptin, resistin, vaspin, visfatin), various inflammatory cytokines, syndecan-1 and C1 esterase inhibitor were measured. RESULTS Thirty-eight patients were included. Resistin levels were significantly higher in the non-survivors versus survivors on Day 1 after burn injury. Hierarchical clustering analysis showed common clusters on Day 1 and at 1 Week after burn injury (resistin, IL-6, IL-8, IL10 and MCP-1). The correlation coefficient of resistin to SOFA score at 1 Week was significant. Logistic regression analysis showed a significant relation of resistin levels on Day 1 with prognosis; the area under the ROC curve for resistin was 0.801. CONCLUSIONS In the acute phase of burns, resistin was associated with other pro-inflammatory cytokines and was related to the severity and prognosis of major burns.

Abstract
Abstract
Background
Edge restenosis still occurs after stent implantation, even by using new generation drug-eluting stents (DES) considered to have favorable biomechanical properties. Mechanical stress imposed on the stent edge are thought to be aggravated by hinge motion at a point between the stented and unstented segments, inducing chronic local inflammation and neointimal overgrowth.
Purpose
The aim of this study was to investigate the association between the development of edge restenosis and hinge motion in right coronary artery (RCA) where the excessive vessel movement is commonly observed.
Methods
Among consecutive 650 lesions in RCA where new generation DESs were implanted between 2009 and 2019, 427 serial lesions with sets of angiographies at baseline and follow-up (6–18 month) were included. In addition to conventional quantitative angiography analysis, hinge angle at stent edges was measured (Fig. 1). All the appropriate data for intravascular imaging were analyzed for both stent edges and reference segments.
Results
Binary restenosis occurred in 43 lesions, and 39 of them were referred to re-intervention. Fifty five percent of them were related to stent edges (15 at proximal and 9 at distal edges). Classical risk factors including diabetes and hemodialysis were more prevalent in the restenosis group (p<0.05). Hinge angle was statistically larger in edge restenosis group than body restenosis or no restenosis group (17.3° vs 11.6° vs 10.6°, p<0.001, Fig. 2). In per-edge analysis, hinge angle, dissection and residual plaque ratio were the independent predictors for binary restenosis (Table 1) with the optimal cut-off value of hinge angle 11.5°. The coexistence of excessive hinge angle and residual plaque burden had an amplified effect on the angiographic stenotic progression at stent edge (p for interaction <0.001) and the incidents of binary restenosis (16.7% vs 1.7% p<0.01, Figs. 3,4).
Conclusion
Substantial stress determined by angulation at the stent edge and its interaction with residual plaque can be considered as one of the plausible mechanisms for edge restenosis. For tortuous RCA lesions, it would be important to decide the stent-landing zone for minimizing hinge motion and optimize the future stent design.

Abstract
Aim For patients with inhalation injury, the indications for early intubation are diverse. The purpose of this study was to identify the most reliable symptoms, physical findings, and medical examinations with which to determine the indications for early intubation in patients with inhalation injury. Methods We retrospectively collected patient data from medical records. Collected data included age, sex, burn size, symptoms, physical findings, carboxyhemoglobin levels (COHb), and bronchial wall thickness (BWT) determined from chest computed tomography images. We analyzed the relationships between these findings and the early intubation. We performed fiberoptic bronchoscopy in all patients, and analyzed the relationships between bronchoscopic severity and other findings. Results Of the 205 patients, 80 patients were diagnosed as having inhalation injury, and 34 patients were intubated. Burn size, facial burns, neck burns, use of accessory respiratory muscles, and COHb seemed to be related with intubation, whereas singed nasal hair was not. If the patients suffered ≥27% total body surface area burn and BWT ≥3.5 mm, the positive predictive value for early intubation was 1.00. If the patients suffered smaller cutaneous burn without neck burn, and their COHb <4.0%, the negative predictive value for early intubation was 0.97. Fiberoptic bronchoscopy findings from above the glottis were mainly related with patients’ symptoms. Findings from below the glottis were mainly related with BWT and COHb. Conclusions Patients’ symptoms, especially use of accessory respiratory muscles, are reliable, and BWT and COHb are also useful tools, for determining the indication for early intubation.

Abstract
Case We describe a patient with severe pancreatitis and ischemic colitis after extensive burn injury. An 81-year-old man presented with a 55% total body surface area burn with inhalation injury. A low-density area was detected in the pancreas on the abdominal computed tomography scan on admission. The clinical course of the patient was good until 28 days after injury when he complained of abdominal pain and distension. Abdominal computed tomography revealed acute pancreatitis and ischemic colitis. Outcome The patient died 59 days after burn injury. Conclusions Extensive burn injury can cause acute pancreatitis. Further work-up is necessary to identify pancreatic complications after severe burn injury.

Abstract
We assessed the efficacy and safety of sitagliptin compared with α-glucosidase inhibitor (αGI) in 120 of Japanese patients with type 2 diabetes mellitus (T2DM) inadequately controlled on stable ≤2 mg/day glimepiride alone [mean hemoglobin A1c (HbA1c) 7.7%] by the randomized, active-controlled, non-inferiority trial. Patients were randomly assigned to receive additional sitagliptin or αGI for 24 weeks. The primary endpoint was change in HbA1c from baseline to week 12. After 12 weeks, sitagliptin reduced HbA1c by -0.44% (p < 0.001) relative to αGI. At 24 weeks, the reduction was almost identical between the groups (-0.091%, p = 0.47). Gastrointestinal disorders were more common with αGI than with sitagliptin, but only minor hypoglycaemia occurred in both groups at similar frequency. These data suggested that sitagliptin was not inferior to αGI for reduction of HbA1c in Japanese T2DM patients receiving glimepiride alone, and well tolerated with minimum risk of gastrointestinal symptoms and hypoglycaemia.

Abstract
The outcomes of primary sclerosing cholangitis (PSC) after living donor liver transplantation (LDLT) in a large series have not been reported. We aimed to determine long-term patient and graft survival, risk factors for PSC recurrence, and the significance of recurrence after LDLT in a Japanese registry. Questionnaires concerning patient characteristics, treatments, and clinical courses were used. Data of 114 patients undergoing primary LDLT for PSC from July 1996 to December 2008 in 29 institutions were evaluated. For strict diagnoses of recurrence, patients with hepatic artery thrombosis (n = 8), ABO-blood-type-incompatible transplantation (n = 8), and established ductopenic rejection (n = 2) were excluded and 96 patients were analyzed for risk factors. Recurrence was diagnosed in 26 patients (27%) at 8 to 79 months after transplantation. Patient, graft, and recurrence-free survivals were 78, 74 and 57% at 5 years after LDLT, respectively. The graft loss rate was 69 versus 23% in patients with versus without recurrence, respectively. Multivariate analysis revealed that high MELD scores, first-degree-relative donors, postoperative CMV infection, and early biliary anastomotic complications were significant risk factors for recurrence. PSC recurrence was a significant risk factor of graft loss but not patient death. PSC recurrence was frequent and had significant impacts on outcomes after LDLT.

Abstract
A facultative alkalophile capable of utilizing 4-chlorobenzoate (4-CBA), strain SB8, was isolated from soil with an alkaline medium (pH 10.0) containing the haloaromatic compound as the carbon source. The strain, identified as an Arthrobacter sp., showed rather extensive 4-CBA-degrading ability. 4-CBA utilization by the strain was possible in the alkaline medium containing up to 10 g of the compound per liter. The 4-CBA-dechlorinating activity of resting cells was almost completely uninhibited by substrate concentrations up to 150 mM. The bacterium dehalogenated 4-CBA in the initial stage of the degradation and metabolized the compound via 4-hydroxybenzoate and protocatechuate. O(2) was needed for 4-CBA dechlorination by resting cells but not by cell extracts. O(2) was inhibitory to the 4-CBA dechlorination activity of cell extracts. These facts suggest dechlorination of 4-CBA by halide hydrolysis and an energy requirement for the transport of 4-CBA into cells.

Abstract
A 57-year-old Japanese woman developed skin eruption, pleuritis, pancytopenia, parotid gland swelling and glomerulonephritis after 7-month treatment with pegylated interferon-α and ribavirin for chronic hepatitis C. Disease-specific autoantibodies such as anti-SSA, anti-SSB, anti-Sm and anti-dsDNA antibodies became positive. The diagnosis of systemic lupus erythematosus and Sjögren’s syndrome was made and treatment with glucocorticoid pulse followed by oral glucocorticoid was started. It is highly probable that interferon-α-induced systemic lupus erythematosus and Sjögren’s syndrome in this case. Interferon-α might be important pathogenically in these diseases.

Abstract
Chronic GVHD (cGVHD) of the liver is an important cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (allo-SCT). It is characterized by the destruction of bile duct epithelium followed by progressive cholestasis, which resembles primary biliary cirrhosis (PBC) clinically and histologically. Bezafibrate (BF) is a widely used agent for hyperlipidemia that is also effective in ursodeoxycholic acid (UDCA)-resistant PBC patients. The putative mechanism in cholestasis is that BF upregulates the expression of phosphatidylcholine flippase on bile canaliculi, facilitates phospholipid output into bile and relieves bile duct damage caused by hydrophobic bile salts. Therefore, the effects of BF in patients with cGVHD of the liver were investigated. Of 87 patients with cGVHD who survived more than 100 days after SCT, 8 were given BF to treat liver cGVHD because of a poor therapeutic response to UDCA and immunosuppressants. The serum alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (gamma-GTP) levels decreased significantly within 1 month after initiation of BF therapy compared with those before BF therapy in all patients (ALP, 964.9.0+/-306.9 to 597.8+/-102.5 IU/l, P=0.012; gamma-GTP, 528.8+/-299.0 to 269.0+/-119.9 IU/l, P=0.012). BF was effective in patients with liver cGVHD, including UDCA-resistant patients. BF could be a novel therapeutic option for liver cGVHD that helps to preserve normal immunity with the antileukemic effect of cGVHD.

Abstract
Endoscopic submucosal dissection (ESD) has been utilized as an alternative treatment to endoscopic mucosal resection for superficial esophageal cancer. We aimed to evaluate the complications associated with esophageal ESD and elucidate predictive factors for post-ESD stenosis. The study enrolled a total of 42 lesions of superficial esophageal cancer in 33 consecutive patients who underwent ESD in our department. We retrospectively reviewed ESD-associated complications and comparatively analyzed regional and technical factors between cases with and without post-ESD stenosis. The regional factors included location, endoscopic appearance, longitudinal and circumferential tumor sizes, depth of invasion, and lymphatic and vessel invasion. The technical factors included longitudinal and circumferential sizes of mucosal defects, muscle disclosure and cleavage, perforation, and en bloc resection. Esophageal stenosis was defined when a standard endoscope (9.8 mm in diameter) failed to pass through the stenosis. The results showed no cases of delayed bleeding, three cases of insidious perforation (7.1%), two cases of endoscopically confirmed perforation followed by mediastinitis (4.8%), and seven cases of esophageal stenosis (16.7%). Monovalent analysis indicated that the longitudinal and circumferential sizes of the tumor and mucosal defect were significant predictive factors for post-ESD stenosis (P < 0.005). Receiver operating characteristic analysis showed the highest sensitivity and specificity for a circumferential mucosal defect size of more than 71% (100 and 97.1%, respectively), followed by a circumferential tumor size of more than 59% (85.7 and 97.1%, respectively). It is of note that the success rate of en bloc resection was 95.2%, and balloon dilatation was effective for clinical symptoms in all seven patients with post-ESD stenosis. In conclusion, the most frequent complication with ESD was esophageal stenosis, for which the sizes of the tumor and mucosal defect were significant predictive factors. Although ESD enables large en bloc resection of esophageal cancer, practically, in cases with a lesion more than half of the circumference, great care must be taken because of the high risk of post-ESD stenosis.

The goal was to clarify the rate of major depressive disorder (MDD) in self-referred patients who visited our late onset hypogonadism (LOH) clinic and the importance of screening of MDD in LOH clinic. Two hundred consecutive self-referred patients who visited our LOH clinic were evaluated. MDD was diagnosed using, the Mini International Neuropsychiatric Interview (MINI) questionnaire. Scores of the Aging Males Symptom (AMS) scale were compared between the MDD and non-MDD groups with and without low testosterone values. Forty-two percent of all patients were categorized into the MDD group. Only 4% of the patients were considered to be LOH. The MDD group had significantly higher scores on the AMS scale than the LOH and non-MDD with normal testosterone groups. In conclusion, significant numbers of undiagnosed MDD patients visited the LOH clinic. Screening for MDD is an essential step in the LOH outpatient clinic.

Abstract
A 74-year-old female underwent surgical treatment for adenocarcinoma of the pancreatic head. Preoperative multi-detector row computed tomography (MD-CT) demonstrated tumor invasion into the accessory right colic vein and the branch of the middle colic artery (MCA), which was not detected by digital subtraction angiography. MD-CT showed anatomical variants in the left hepatic artery arising from the left gastric artery, and the right posterior hepatic artery arising from the superior mesenteric artery. Three-dimensional reconstruction CT generated a clear picture of the anatomy of the region concerned, which is essential for a safe operation. The MD-CT findings were highly consistent with the intraoperative findings. We have demonstrated that MD-CT is an important and highly accurate modality for pancreatic surgery.

Abstract
Elongin A is a transcription elongation factor that increases the overall rate of mRNA chain elongation by RNA polymerase II. To gain more insight into the physiological functions of Elongin A, we generated Elongin A-deficient mice. Elongin A homozygous mutant (Elongin A(-/-)) embryos demonstrated a severely retarded development and died at between days 10.5 and 12.5 of gestation, most likely due to extensive apoptosis. Moreover, mouse embryonic fibroblasts (MEFs) derived from Elongin A(-/-) embryos exhibited not only increased apoptosis but also senescence-like growth defects accompanied by the activation of p38 MAPK and p53. Knockdown of Elongin A in MEFs by RNA interference also dramatically induced the senescent phenotype. A study using inhibitors of p38 MAPK and p53 and the generation of Elongin A-deficient mice with p53-null background suggests that both the p38 MAPK and p53 pathways are responsible for the induction of senescence-like phenotypes, whereas additional signaling pathways appear to be involved in the mediation of apoptosis in Elongin A(-/-) cells. Taken together, our results suggest that Elongin A is required for the transcription of genes essential for early embryonic development and downregulation of its activity is tightly associated with cellular senescence.

Abstract
BACKGROUND AND AIMS Serum antibodies to carbonic anhydrase (CA) II have been reported in patients with autoimmune pancreatitis (AIP) and Sjogren's syndrome (SjS). However, their significance in the pathogenesis of these diseases is controversial. The aim of this study was to identify serum antibodies to CA isozymes, which are expressed in ductal cells of the pancreas. METHODS Recombinant proteins of human CAs IV, IX, and XII were obtained using a bacterial expression system, and five CA IV peptides with theoretically high antigenicity were synthesised. Western blotting and enzyme linked immunosorbent assay (ELISA) were used to detect serum antibodies to the CA isozymes. RESULTS The first screening analysis by western blot showed serum antibodies to CA IV among three CA isozymes in patients with idiopathic chronic pancreatitis, including AIP patients. Further analysis by ELISA showed a significantly increased prevalence of serum antibodies to the truncated CA IV protein and the CA IV synthetic peptide (LGS LTT PTC DEK VVW TVF REP I) in patients with definite AIP (4/15 and 6/20, respectively; p<0.01), probable AIP (6/14 and 3/14; p<0.02), and SjS (9/20 and 8/40; p<0.001) compared with normal controls (0/26). There was no significant difference in the antibody prevalence rates between normal controls and patients with alcoholic chronic pancreatitis (2/15 in each) or pancreatic cancer (2/14 and 1/14, respectively). The presence of serum antibodies to the CA IV peptide showed significant correlations with serum gamma-globulin and IgG levels in AIP patients. CONCLUSIONS These findings suggest that CA IV may be a target antigen that is commonly expressed in epithelial cells of specific tissues involved in AIP and its related diseases.

Abstract
BACKGROUND AND STUDY AIMS We undertook this retrospective study to evaluate the frequency and prognosis of endoscopic treatment of laterally spreading tumors (LSTs) in the rectum. The recurrence rate for lesions of the lower rectum was compared with that of the upper rectum. PATIENTS AND METHODS During the period from July 1989 to June 2002, a total of 1237 rectal tumors were detected. LSTs accounted for 6.9 % (85/1237) of all rectal tumors. A total of 224 tumors of the lower rectum were detected among the 1237 rectal tumors. LSTs accounted for 16.1 % (36/224) of all the lower rectal tumors. From 85 LST lesions, 67 were evaluated for their prognosis after endoscopic mucosal resection (EMR). Patients whose LSTs had been resected were followed up by endoscopy at the following frequencies: once 15 (22.4 %); twice (more than 1 year), 20 (29.9 %); three times (more than 3 years), 21(31.3 %); and four times or more (more than 5 years), 11 (16.4 %). RESULTS A total of 67 patients with endoscopically treated LSTs were followed up by endoscopy. We observed recurrences in two lesions of the upper rectum (2/38, 5.3 %) and five lesions of the lower rectum (5/29, 17.2 %) (P = 0.2364); all seven lesions were resected piecemeal. LSTs whose horizontal margin reached the pectinate line frequently recurred in the lower rectum, at a rate of 80 % (4/5). However, all patients were completely cured by additional endoscopic resections, the greatest number of treatments being four. CONCLUSION For early detection of recurrence and successful endoscopic cure, further colonoscopic examination within a few months after the first treatment is necessary.

Abstract
Nephrotoxicity is the most prominent side effect of the new immunosuppressive drug FK506. Some of the histopathological changes associated with cyclosporine (CyA) nephrotoxicity such as tubular vacuolization and glomerular thrombosis have also been reported with FK506 therapy. In this study we used kidney tubular cells in culture to address the issue of FK506- and CyA-induced tubular damage. Exposure of tubular cells to high concentrations of FK506 or CyA (10, 50 and 100 microM) induced a time- and dose-dependent cell injury in vitro characterized by a direct cytotoxic effect on tubular cells as expressed by release of 3H-thymidine from prelabelled cells, N-acetyl-beta-D-glucosaminidase (NAG) release and cell detachment. Ultrastructural changes (vacuolization, swelling and mitochondrial enlargement) and inhibition of the growth (DNA and RNA synthesis) of cultured tubular cells were also observed at high concentrations of FK506 and CyA. These concentrations are higher than those reached in clinical situations, but close to the concentrations that may be reached by FK506 or CyA in tissues. Low concentrations of FK506 and CyA (1, 0.1 and 0.01 microM) were not cytotoxic and induced only a minimal inhibitory effect on the growth of tubular cells in vitro. At the same concentration CyA induced more cell detachment, more NAG release and a stronger inhibitory effect on cell growth than FK506 (P < 0.01). Since an evident cytotoxic effect was observed only at high concentrations, we can speculate that tubular toxicity is due to the accumulation of drug in the cells inducing cell disruption and death.

Abstract
CYP3A5 expression is regulated by single-nucleotide polymorphisms (SNPs). The CYP3A5 genotype might contribute to a marked interindividual variation in CYP3A-mediated metabolism of drugs. Nifedipine is a typical substrate of CYP3A4 and CYP3A5 in vitro. The aim of this study was to elucidate the influence of the CYP3A5 genotype on nifedipine disposition in healthy subjects. A single capsule containing 10 mg of nifedipine was administered to 16 healthy male Japanese subjects (eight subjects: CYP3A5(*)1/(*)3; eight subjects: CYP3A5(*)3/(*)3). Blood samples were collected to analyze the pharmacokinetics of serum nifedipine and nitropyridine metabolite (M-I). The area under the plasma concentration-time curve (AUC), the peak plasma concentration (C(max)) and the terminal half-life (t(1/2)) of nifedipine, and the ratio of the nifedipine AUC to M-I AUC showed large intragroup variations, but no significant differences between the two genotypes. Based on the present findings, the functional relevance of CYP3A5 polymorphism should be re-evaluated in clinical trials.

Abstract
The efficacy of electrocardiography (ECG) in the diagnosis of left ventricular (LV) hypertrophy in 890 males, newly recruited to Japanese professional sumo wrestling (15.9 +/- 1.8 years of age, 177.8 +/- 4.7cm, 107.3 +/- 4.7kg), was tested by comparing simple, widely employed ECG criteria (Sokolow-Lyon chest and limb lead voltages and Cornell voltage with repolarisation criteria) with echocardiographic evaluations of LV mass indexed to body surface area. LV hypertrophy was defined as a LV mass index > 2 SD above the mean value obtained from 115 age-matched, normotensive, sedentary, male controls. The prevalence of LV hypertrophy as determined by echocardiography was 9.0% the entire group and was 8.3% among the 484 normotensives. The sensitivities of the three ECG criteria were < or = 36.0%, and their specificities were 70.0-99.0%. In contrast to the Sokolow-Lyon chest lead criteria, the diagnostic performance of the Cornell criteria was little affected by body mass index (BMI), and stepwise regression revealed that BMI did not significantly correlate with Cornell voltage. Still, the diagnostic efficacy of ECG was not sufficient to merit its use for primary recognition of LV hypertrophy among professional sumo wrestlers. Indeed, LV hypertrophy will likely go undetected by ECG in most overweight muscular athletes.

Abstract
Three cDNA homologues of carbonic anhydrase with unknown biological functions have been reported: carbonic anhydrase-related proteins (CA-RP) VIII, X, and XI. In the present study, we produced monoclonal antibodies to these CA-RPs and studied their regional and cellular distributions in the human adult and fetal brains by immunohistochemical analysis. In the adult brain, CA-RP VIII was expressed in the neural cell body spreading to most parts of the brain. CA-RP X was expressed in the myelin sheath and its expression was shown in the cytoplasm of cultured tumor cells by immunocytochemical analysis. CA-RP XI was expressed in the neural cell body, neurites, and astrocytes in relatively limited regions of the brain. In the fetal brain, CA-RP VIII and XI were expressed in the neuroprogenitor cells in the subventricular zone as early as the 84th day of gestation and subsequently detected in the neural cells migrating to the cortex. CA-RP X first appeared in the neural cells in the cortex at the 141st day. In the choroid plexus, the epithelial cells gave CA-RP VIII and XI expressions in both adult and fetal brains. From the findings in the present study on the distribution and the developmental expression of CA-RP VIII, X, and XI in the human brain we suggest that these CA-RPs play roles in various biological process of the CNS.

Abstract
Pancreatitis-associated gene mutations have been reported in patients with hereditary pancreatitis and idiopathic pancreatitis in the Caucasian population and involve the cationic trypsinogen gene, the pancreatic secretory trypsin inhibitor gene and the cystic fibrosis transmembrane conductance regulator gene. In the Japanese population, mutational screening analyses of these genes have shown several mutations. The present study reviews previous reports from Japan in order to evaluate the racial specificity of pancreatitis-associated gene mutations.

Abstract
BACKGROUND/AIM It is well known that Helicobacter pylori changes its shapes according to various environmental conditions. The aim of this study was to examine the morphological differences between H. pylori in the duodenum and that in the stomach. METHODS Duodenal biopsy specimens were obtained from patients with duodenal mucosal lesions, and these specimens were then histopathologically examined. Morphological and genetic properties of cultured H. pylori isolates were analyzed. RESULTS H. pylori was identified in 16 out of 50 duodenal biopsy specimens. Along with the regular form, we found a fine form of H. pylori in the gastric metaplastic mucosa of ten duodenal specimens that was shorter in length and thinner in diameter than the regular helical form. There were no detectable differences between the ureA-ureB polymorphism of the duodenal fine form and that of gastric regular form in a single patient. As compared with patients without H. pylori in the duodenum, the prevalence of recurrent duodenal ulcers significantly increased in patients with the fine form (p < 0.05), but not in patients with the regular form. CONCLUSION The fine form of H. pylori in the metaplastic duodenal mucosa could result from its adaptation to the duodenal environment and may be associated with the recurrence of a duodenal ulcer.

Abstract
We generated aromatase gene knockout mice (ArKO mice) by targeting disruption of Cyp19, which encodes an enzyme responsible for conversion of androgens to estrogens. We found that ArKO males developed hepatic steatosis spontaneously with aging, indicating that the function of Cyp19 is required to maintain constitutive lipid metabolism in male mice. Plasma lipoprotein analysis using a gel permeation chromatography revealed that high density lipoprotein (HDL)-cholesterol levels were slightly higher in ArKO males than in wild-type males, whereas no other obvious alternations in the profiles were detected. Nevertheless, analysis of lipoprotein compositions by SDS-polyacrylamide gel electrophoresis demonstrated apparent reduction in the amounts of apolipoprotein E, functioning in receptor-mediated clearance of lipoproteins in the liver, in the IDL/LDL fraction of ArKO males as compared with that of wild-type males. Biochemical analysis on the ArKO livers revealed suppression of mRNA expression and activity of enzymes involved in fatty acid beta-oxidation. The impairment was reversed to the wild-type levels by treatment with 17beta-estradiol or bezafibrate, the latter is a synthetic peroxisome proliferator. These findings indicated a pivotal role of estrogen in supporting constitutive hepatic expression of genes involved in fatty acid beta-oxidation and in maintaining lipid homeostasis.

Abstract
Therapeutic modalities for the obliteration of collateral vessels connecting the portal venous system with the systemic circulation, transjugular retrograde obliteration (TJO) and balloon-occluded retrograde transvenous obliteration have recently been developed, and several satisfactory results have been reported with their use. We report a case of ruptured gastric fundal varices treated with TJO after endoscopic variceal ligation (EVL). In our case, variceal bleeding was controlled successfully with EVL and varices were eradicated with TJO.

Abstract
BACKGROUND Clinical trials of hypothermic therapy in asphyxiated infants have started recently. However, clinical studies have been delayed by the difficulty in selecting infants with a bad neurological prognosis and by the concern regarding adverse effects of hypothermia. The purpose of this study is to examine the effects of systemic cooling on cerebral metabolism (CMR) and the regional cerebral blood flow (rCBF) in newborn piglets. METHODS The rCBF in the seven parts of the brain were measured with colored microspheres. The blood samples for the measurement of cerebral oxygen consumption (CMRO2) and cerebral glucose consumption (CMRglc) was collected from the umbilical artery and the superior sagittal sinus. RESULTS Reductions of cerebral cortex temperature to 32 degrees C decreased blood flow in all brain regions. In particular, blood flow in the brainstem decreased more significantly than in any other region. The total cerebral blood flow (CBF), CMRO2 and CMRglc, respectively, decreased to 32.3+/-3.9 mL/100 g per min, 2.8+/-1.0 mLO2/100 g per min and 22+/-12 mmol/100 g per min at 32 degrees C (41, 53 and 46% of the initial value). The CBF decreased in parallel with CMRO2 and CMRglc down to 35 degrees C, but CBF decreased to a greater extent than CMRO2 and CMRglc at below 35 degrees C. CONCLUSIONS The indication of hypothermic therapy and the degree of cooling have to be performed very carefully. Systemic cooling is especially dangerous for the total asphyxiated infants who might have damage to the brainstem because the blood flow in the brainstem has significantly decreased during hypothermia.

Abstract
We report a case of small cell carcinoma of the urinary bladder. A 60-year-old man with microscopic hematuria was referred to our hospital. Cystoscopy revealed a sessile tumor on the left lateral wall of the urinary bladder. The patient underwent transurethral resection of the bladder tumor (TUR-Bt). Because of muscle invasion (pT2), total cystectomy was recommended, but was not performed because the patient would not give consent for the operation. Six months after TUR-Bt, invasive bladder tumor recurred and total cystectomy was performed. Pathological examination of the operative specimen revealed small cell carcinoma. Adjuvant combined therapy of irradiation and chemotherapy (nedaplatin and etoposide) was ineffective. Metastases to retroperitoneal lymph nodes, lung and liver were detected soon after the adjuvant therapy. The patient died 15 months after his first visit to our hospital.

Abstract
A 56-year-old woman, who had been suffering from idiopathic cold agglutinin disease and treated unsuccessfully with prednisolone and cyclosporine A for 6 months, was referred to our hospital in November 1998. She was given methylprednisolone pulse therapy followed by low-dose cyclophosphamide, but her anemia did not improve. We then began administration of intermittent high-dose cyclophosphamide (1,200 mg/day, every 4 weeks), and this resulted in a dramatic increase of her hemoglobin level and improvement of her symptoms. She is currently receiving 500 mg of cyclophosphamide every 2 months and showing a good response. Intermittent high-dose cyclophosphamide therapy can be an effective treatment for refractory cold agglutinin disease.

Abstract
BACKGROUND AND STUDY AIMS The aim of this study was to reveal the clinical features of serrated colonic adenoma by investigating its endoscopic features using a magnifying videoscope. MATERIALS AND METHODS 68 colorectal serrated adenomas presented for colonoscopic examination were included in this study. A magnifying videoscope with a zoom ranging from x 1 to x 100 magnification was employed to observe the pit patterns of colonic lesions, and 39 of the serrated adenoma specimens were evaluated using this. Some pit patterns appeared as elongated oval and stellar-like orifices of the crypts; we termed these type which was detected III(SA) patterns. Other pit patterns showed a flower petal-like or pineal form, and this was termed a type IV(SA) pit pattern. RESULTS In the entire sample of serrated adenomas, 53 were of the protruded type, and 15 were superficial, for a protruded/superficial ratio of 3.5 : 1. The protruded type of serrated adenoma predominated in the distal portion. The superficial type was preferentially located in the proximal portion of the colon (P < 0.0001). Among the 13 superficial types in which the magnifying videoscope was used, all 13 showed the type III(SA) basic pit pattern. In these serrated adenomas of the superficial type, an additional IV(SA) pit pattern was found in 23.1% (3/13), which was detected in 53.8% (14/26) in the protruded type. Small serrated adenomas measuring less than 10 mm in diameter were preferentially mild to moderate atypia (odd's ratio = 15.9, P = 0.0216). CONCLUSION The pit pattern may prove useful for the endoscopic diagnosis of serrated adenoma. Furthermore, endoscopic treatment is indicated for serrated adenoma; in particular those of 10 mm or more in diameter should be treated because of the possibility of high-grade glandular intraepithelial neoplasia.

Abstract
BACKGROUND Nitric oxide (NO) is a potent mediator of hepatic sinusoidal hemodynamics that is synthesized in the hepatic stellate cells (Ito cells, fat-storing cells) and affects these cells. NO production may depend on the induction of inducible nitric oxide synthase and on transport of extracellular L-arginine. The precise mechanism that controls NO production in stellate cells was characterized recently. METHODS Kinetic analysis of L-arginine transport and reverse transcription-polymerase chain reaction for cationic amino acid transporter (CAT) were carried out by using stellate cells prepared from the male Wistar rat. The effect of ethanol on L-arginine transport and NO production of stellate cells was assessed in the presence of tumor necrosis factor (TNF)-alpha and interferon (IFN)-gamma. RESULTS The L-arginine transport system functioning in the hepatic stellate cells was system y+, possibly mediated by CAT-1 and CAT-2B (Km approximately 50 microM). IFN-gamma in combination with TNF-alpha induced NO production with an enhancement in CAT-2B mRNA expression and L-arginine transport, whereas L-arginine transport and NO production were suppressed by coincubated ethanol. CONCLUSIONS In hepatic stellate cells, ethanol has suppressive effects on NO production and extracellular L-arginine transport in the presence of TNF-alpha and IFN-gamma. The estimated Km of L-arginine transporter in hepatic stellate cells is very similar to the physiological L-arginine concentration in portal vein. Our findings may support the merit of further studies on the modulation of NO production via access to portal blood L-arginine concentration to control disturbed hepatic sinusoidal blood flow in patients with alcoholic liver disease.

Abstract
AIM To investigate the relation between gestational age, birth weight, and antenatal corticosteroid administration and the time of ductus venosus closure. METHODS Ninety eight neonates of 30-41 weeks gestational age were studied by daily ultrasonography until ductus venosus closure. RESULTS In neonates of 30-33 weeks gestational age, the ductus venosus closed at 6.0 (2.4)days (mean (SD)); in those of 34-36 weeks gestational age, it closed at 6.1 (2.8) days; and in those of 37-41 weeks gestational age, it closed at 4.2 (2.1) days. The effect of antenatal administration of corticosteroids on the time of closure was also investigated in neonates of 30-34 weeks gestational age. Closure occurred by 5.5 (2.4) days in the group given corticosteroids compared with 7.5 (2.1) days in the remainder. CONCLUSIONS The ductus venosus closed sooner after birth in neonates of greater gestational age or higher birth weight. Antenatal corticosteroid administration had a significant effect in promoting closure.
