Abstract
A prospective clinical study was conducted to evaluate the safety, feasibility, and efficacy of endoscopic ultrasound (EUS)-guided choledochoduodenostomy (CDS) with direct metallic stent placement using a prototype forward-viewing echoendoscope. The indication for EUS - CDS in this study was lower biliary obstruction only, and not failed endoscopic biliary drainage, because the aim was to evaluate EUS - CDS for first-line biliary drainage therapy. The technical and functional success rates were 94 % (17 /18) and 94 % (16 /17), respectively. Early complications (focal peritonitis) were encountered in two patients (11 %). No patients developed late complications. EUS - CDS with direct metallic stent placement using a forward-viewing echoendoscope was generally feasible and effective for malignant distal biliary tract obstruction. The forward-viewing echoendoscope was useful, especially for deploying the metallic stent.

Abstract
Mechanical vibration enhances the cytoplyasmic maturation of in vitro-matured (IVM) pig oocytes (Mizobe et al. 2010 J. Reprod. Dev. 56, 285–290), as well as the development of in vitro-cultured (IVC) bovine embryos (Fujita et al. 2010 Rakuno Gakuen University Graduation thesis,1–36). In this study, the effects of intervals of mechanical vibration during in vitro culture, after IVF, on the development of embryos derived from low-quality oocytes were examined. Cumulus-oocyte complexes (COC) were collected by aspiration of ovarian follicles (diameter = 2 to 6 mm) obtained from a local abattoir. In this experiment, only grade 3 oocytes (i.e. those with one layer or partially remaining cumulus cells and normal cytoplasm) were used. Groups of 20 COC were matured in 100-μL droplets of in vitro TCM-199 supplemented with 5% calf serum and 0.02 AU mL–1 of FSH at 38.5°C under an atmosphere of 5% CO2 in air for 20 h. Matured COC were inseminated with 5 × 106 sperms mL–1 for 18 h. After 18 h of gamete co-culture, the presumptive zygotes were cultured in CR1aa medium supplemented with 5% calf serum at 38.5°C under an atmosphere of 5% O2, 5% CO2, and 90% N2 for 9 days (fertilization = Day 0). Presumptive zygotes were cultured in vitro without mechanical vibration (control; n = 467) and with mechanical vibration for 5 s at 5 min (n = 180), 10 min (n = 180), 15 min (n = 180), and 60 min (n = 200) for 9 days. Embryo development was evaluated for cleavage and blastocyst rates, on Days 3 and 7 to 9 after IVF, respectively. The cleavage and blastocyst formation rates were analysed by the chi-squared test. Vibration at 15-min intervals increased (P < 0.05) cleavage rate compared to 5 min, 60 min, and control (control: 66.2 ± 22.1%; 5 min: 49.4 ± 10.2%; 10 min: 70.0 ± 7.7%; 15 min: 86.2 ± 6.6%; and 60 min: 64.0 ± 8.5%).The highest (P < 0.05) blastocyst rate among the experimental groups was found with 15-min intervals for vibration (control: 21.6 ± 9.2%; 5 min: 15.0 ± 5.3%; 10 min: 22.8 ± 1.8%; 60 min: 21.5 ± 5.0%). These results indicated that the cleavage and blastocyst formation rates of IVM-IVF-IVC bovine embryos derived from low-quality oocytes can be improved by physical stimulus during IVC. In addition, it was shown that 15-min intervals of mechanical vibration elicited the highest benefit for the development of embryos.

Abstract
In this study, we attempted to clarify the associations between various sleep disturbance symptoms and the frequency and amount of alcohol use among Japanese adolescents. This study was designed as a cross-sectional sampling survey. A self-administered questionnaire survey was administered to students enrolled in randomly selected junior and senior high schools throughout Japan. A total of 99,416 adolescents responded, and 98,867 questionnaires were subjected to analysis. The prevalence rates of sleep disturbance in the 30 days preceding the day of the survey were as follows: subjectively insufficient sleep (SIS) (boys: 37.6%, girls: 38.7%); short sleep duration (SSD) with less than 6 h of sleep (boys: 28.0%, girls: 33.0%); difficulty initiating sleep (DIS) (boys: 12.5%, girls: 14.1%); difficulty maintaining sleep (DMS) (boys: 10.1%, girls: 10.9%); and early morning awakening (EMA) (boys: 5.1%, girls: 5.0%). Adolescents reporting one or more symptoms of DIS, DMS, and EMA were classified as having insomnia, and its prevalence was 21.5%. The prevalence of each symptom of sleep disturbance increased significantly with the number of days on which alcohol was consumed in the previous 30 days and the amount of alcohol consumed per drinking session (p < 0.01). Multiple logistic regression analyses showed that the adjusted odds ratio (AOR) for each symptom of sleep disturbance, except SIS and EMA, tended to increase with the number of days on which alcohol was consumed and the amount of alcohol consumed per drinking session. The prevalence of sleep disturbance is particularly high among adolescents drinking alcohol. The risk of having each symptom of sleep disturbance, except SIS and EMA, increases with the number of days on which alcohol was consumed and the amount of alcohol consumed per drinking session. These findings reconfirm the need to eliminate underage drinking to ensure good sleep among adolescents.

Abstract
Infantile systemic lupus erythematosus (iSLE) is extremely rare. Patients with iSLE usually become severely unwell and have poor prognosis. Epstein-Barr virus (EBV) infection has been implicated in the development of SLE in both adults and children. Recently, we experienced a case of iSLE with severe lupus nephritis (LN) and EBV infection. A 14-month-old Japanese boy was diagnosed with iSLE according to the American Rheumatism Association criteria. Renal biopsy showed LN classified as International Society of Nephrology/Renal Pathology Society class IV-G (A), and liver biopsy showed lupus hepatitis. Steroid pulse treatment resulted in improvement of the levels of serological markers of SLE such as double-stranded DNA and complement, but his proteinuria worsened and he developed acute nephritic-nephrotic syndrome. Monthly intravenous cyclophosphamide (IVCY) therapy dramatically reduced his proteinuria and led to complete remission (urinary protein/creatinine ratio <0.1 mg/mg), with gradual improvement in levels of serological markers. EBV antibody titers and EBV polymerase chain reaction (PCR) of peripheral blood lymphocytes suggested that the onset of iSLE might have been associated with EBV infection. At his 2-year follow-up visit, he was healthy and remained in complete remission. We conclude that IVCY treatment might be well tolerated and effective in cases of iSLE. EBV infection might play an important role in the pathogenesis of iSLE.

Abstract
BACKGROUND Angiotensin-converting enzyme (ACE) 2 is a homolog of ACE and is thought to be a potent counter-regulator against ACE activity. However, the role of ACE2 has not been investigated in pediatric patients with IgA nephropathy (IgAN). This study was performed to examine the relationship between ACE2 expression and the development of pediatric IgAN. METHODS We performed immunohistochemical analysis of ACE2 and ACE in 39 patients with pediatric IgAN and 14 patients with minor glomerular abnormalities, and elucidated the effects of various cytokines on ACE2 expression in cultured human mesangial cells. RESULTS ACE2 expression levels in glomeruli and tubules were positively correlated with the mesangial hypercellularity score, while ACE expression levels in glomeruli and tubules are not. Multiple regression analysis showed that the mesangial hypercellularity score correlated with the ACE2 expression level in glomeruli and the urinary protein-creatinine ratio. In IgAN patients not treated with a renin-angiotensin system blocker, ACE2 expression levels in glomeruli were significantly increased compared to patients with minor glomerular abnormalities. IgAN patients treated with a renin-angiotensin system blocker did not show this increase in ACE2 expression. Furthermore, cultured human MC showed increased ACE2 mRNA and protein after treatment with IL-1β, a pro-inflammatory cytokine in IgAN. In fact, glomerular expressions of IL-1β were remarkably increased in patients with IgAN. CONCLUSION These data indicate that ACE2 expression in glomeruli is associated with mesangial hypercellularity in early lesions of pediatric IgAN.

Abstract
The objective of this study was to evaluate cytokines in unstimulated whole saliva (UWS) of oral squamous cell carcinoma (OSCC) patients as compared to those with pre- and post-operation for evaluation as markers of OSCC. Sixteen OSCC patients were included in this study. Cytokine concentrations in resting saliva were measured using a Bio-Plex suspension array system. Only interleukin-1 (IL-1) beta showed significantly different cytokine concentration in saliva between pre- and post-operation. IL-1 beta was released from cultured OSCC cells confirmed by ELISA and immunohistochemistry. From this study, IL-1 beta in UWS may be useful for detection of early stage OSCC. More studies are needed to accept the utility of IL-1 beta in UWS for predicting, diagnosis and evaluation of OSCC.

Abstract
Minimally invasive procedures for treatment of disease have become increasingly popular and require specialized instruments and precise imaging guidance. We here propose a technique of minimally invasive surgery with ultrasound echo-guided procedures as a less traumatic and invasive procedure to get particulate cancellous bone and marrow from the iliac crest for cleft palate. This technique has been used successfully at our institutions. Our experience suggests that it can provide reliable ultrasound echo imaging-guided surgery.

Abstract
OBJECTIVES The aim of study was to determine the associations of work hours and actual availability of weekly rest days with the onset of lifestyle-related diseases such as obesity, hypertension, hypertriglyceridemia, low levels of high-density lipoprotein (HDL) cholesterol and hyperglycemia. METHODS For this longitudinal study, we used data from checkups conducted in 1999 and 2006 for 30,194 men who worked for a local public institution in Japan. We calculated the cumulative incidence rates of onset of obesity, hypertension, hyperglycemia, hypertriglyceridemia and low HDL cholesterol over this 7-year period and performed a χ2 test to determine the association between the above diseases and work conditions (work hours and actual availability of weekly rest days) at the time of the baseline survey. We then performed multiple logistic regression analysis of the diseases that showed significant associations. RESULTS The adjusted odds ratio for the onset of hypertriglyceridemia in subjects who worked ≥9 hours was high (1.11 [95% CI: 1.02-1.22], p=0.02) in comparison with those who worked <9 hours. The adjusted odds ratio for the onset of hypertriglyceridemia in subjects who could not often take weekly rest days was high (1.13 [95% CI: 1.01-1.27], p=0.03) in comparison with those who were able to take most of the available weekly rest days off work. CONCLUSIONS These results show that work hours and actual availability of weekly rest days independently predict the onset of hypertriglyceridemia. Working only regular hours and taking advantage of weekly rest days can contribute to the prevention of hypertriglyceridemia.

Abstract
New camptothecin (CPT) derivatives have recently been synthesized following the finding that CPT has strong antitumor activity due to its inhibition of topoisomerase I through the formation of stable topoisomerase I-DNA cleavable complexes, but has not been clinically used due to its pronounced toxicity. 7-ethyl-10-hydroxy-CPT (SN-38), a metabolite of the CPT derivative 7-ethyl-10-[4-(1-piperidino)-1-piperidino] carbonyloxy-CPT(CPT-11), plays an essential role in mediating the antitumor effect of CPT-11. However, the reasons for the cytotoxicity of SN-38 remain unclear. In this study, we demonstrated using results of DNA fragmentation assay and cell cycle analysis that SN-38 and CPT both induce apoptosis in L1210 murine leukemia cells. We demonstrated in addition that enforced expression of the bcl-2 gene in L1210 cells by MPZenNeo (bcl-2) retroviral gene transfer increased resistance to the apoptosis induced by SN-38 and CPT. These findings suggest the possibility that the bcl-2 gene impedes the activity of a common pathway for apoptosis induced by SN-38 and CPT.

An extra saturable absorber, introduced downstream after a low-gain optical parametric chirped-pulse amplification (OPCPA) preamplifier, has improved the temporal contrast in the system to 1.4×10(12) on the subnanosecond time scale at 70 TW power level. We have achieved 28 J of uncompressed broadband output energy with this system, indicating the potential for reaching peak powers near 600 TW.

Abstract
BACKGROUND/AIMS Hydrogen peroxide-inducible clone-5 (Hic-5) is a transforming growth factor-β(1) (TGF-β(1))- and hydrogen peroxide (H(2)O(2))-inducible focal adhesion protein that may be necessary for maintaining the myofibroblastic phenotype in pathological scar formation. To investigate the involvement of Hic-5 in the pathogenesis of glomerulonephritis (GN), we examined the glomerular expression of Hic-5 in human and rat GN as well as the regulation of Hic-5 by TGF-β(1) in vitro. METHODS AND RESULTS Immunohistochemical analyses showed that the expression of Hic-5 was increased in mesangial cells (MCs) in human mesangial proliferative GN. Hic-5 expression was significantly correlated not only with the levels of α-smooth muscle actin (α-SMA) and TGF-β(1), the accumulation of extracellular matrix, and the number of glomerular cells, but also with the urinary protein level in patients with GN. Glomerular Hic-5 expression increased in parallel with α-SMA expression in a rat model of mesangial proliferative GN. Combined therapy with an angiotensin type I receptor blocker and an antioxidant in this model improved the histology and the expression of Hic-5 and α-SMA. TGF-β(1) upregulated Hic-5 and α-SMA protein levels in human cultured MCs. CONCLUSION Our findings suggest that Hic-5 is involved in changes in the MC phenotype to produce abnormal extracellular matrix remodeling in GN.

Abstract
BACKGROUND The chemotherapy for small-cell lung carcinoma (SCLC) has been adopted for advanced extrapulmonary neuroendocrine carcinomas (EP-NECs). The aim of this study was to clarify the efficacy of standard SCLC regimens when used to treat EP-NECs and to compare the outcome with that for SCLC. METHODS We reviewed the medical records of 136 patients (41 with EP-NEC and 95 with SCLC) who were treated using a platinum-containing regimen for advanced disease between January 2000 and October 2008 at our hospital. RESULTS The primary site of the EP-NEC was the gastrointestinal tract in 18 patients (GI tract group); the liver, biliary tract or pancreas in 16 patients (HBP group), and other sites in 7 patients ('others' group). The response rate in the SCLC patients was 77.8%, and the response rate in the EP-NEC patients was 30.8% (37.5% in the GI tract group, 12.5% in the HBP group, and 57.1% in the 'others' group). The median survival time for the SCLC patients was 13.6 months, while that for the EP-NEC patients was 9.2 months (14.9 months in the GI tract group, 7.8 months in the HBP group, and 8.9 months in the 'others' group). A multivariate analysis demonstrated that a poor performance status, liver involvement, and the treatment regimen were independent unfavorable prognostic factors. CONCLUSION The response rate and prognosis of the patients with advanced EP-NECs were worse than those of the patients with SCLC in this study. The Eastern Cooperative Oncology Group performance status, liver involvement, and treatment regimen had a larger impact on the prognosis than the primary tumor site, as demonstrated by multivariate analysis.

Abstract
Excessive renin-angiotensin system (RAS) activation within the kidney induces not only renal oxidative stress but also renal scarring and dysfunction. This study examined the effects of an angiotensin II (Ang II) type I receptor (AT1R) blocker (ARB) on the progression of renal injury in rat anti-glomerular basement membrane glomerulonephritis (GN), with a particular focus on the participation of glomerular RAS activation in glomerular structural alterations, inflammation, and oxidative stress. Nephritic rats were divided into 2 groups and treated with vehicle or ARB until day 28. Treatment with ARB improved proteinuria significantly in nephritic rats. Vehicle-treated nephritic rats developed crescentic GN accompanied by marked macrophage infiltration and the enhanced expression of glomerular α-smooth muscle actin (α-SMA), angiotensinogen (AGT), Ang II, AT1R, and NADPH oxidase (Nox2) on days 7 and 28 of GN. ARB improved pathologic alterations such as crescent formation and glomerulosclerosis, and it had a significant inhibitory effect on the levels of these parameters on day 28 of GN. Enhanced superoxide production in nephritic glomeruli was decreased also by ARB. Moreover, Ang II and transforming growth factor beta (TGF-β) in the supernatant of cultured glomeruli was increased significantly in vehicle-treated nephritic rats whereas ARB inhibited the production of these compounds significantly on day 28. These results indicate that increased glomerular RAS activity and the resulting Ang II play important roles in progressive glomerular injury-the induction of oxidative stress and TGF-β expression, and they suggest that AT1R blockade attenuates proteinuria and progressive glomerular remodeling via the suppression of glomerular RAS activation in GN.

Abstract
BACKGROUND Metastasis to the pancreas (MP) is a rare entity that is difficult to identify by imaging alone. Few reports have described endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (FNA) findings. Herein, we try to describe the EUS and EUS-FNA characteristics of MP. METHODS This retrospective study compared 28 patients with MP (13 males; mean age: 60.1 ± 12.6 years) and 60 control patients (30 males; 62.7 ± 11.5 years) with pancreatic ductal adenocarcinoma (PDAC). All lesions were characterized by EUS, and MP was diagnosed by EUS-FNA (n = 16), surgery (n = 6) or both (n = 6). RESULTS Multivariate logistic regression revealed that the presence of regular borders (p = 0.004; OR: 8.81, 95% CI: 1.97-39.4), the absence of retention cysts (p = 0.045; OR: 12.5, 95% CI: 1.06-147.0), and the absence of main pancreatic duct (MPD) dilation (p = 0.003; OR: 8.18, 95% CI: 2.04-32.8) were predictors of MP rather than PDAC. The EUS-FNA sampling adequacy was 95.4% (21/22), and the correct diagnosis was obtained in 95.2% (20/21) of cases when K-ras mutation analysis and/or immunostaining were added. CONCLUSION The presence of regular borders, the absence of retention cysts and the presence of nondilated MPD on EUS indicate MP rather than PDAC. This diagnosis can be accurately confirmed by EUS-FNA with immunostaining and/or K-ras analysis.

Abstract
Focal adhesions play a critical role as centers that transduce signals by cell-matrix interactions and regulate fundamental processes such as proliferation, migration, and differentiation. Focal adhesion kinase (FAK), paxillin, integrin-linked kinase (ILK), and hydrogen peroxide-inducible clone-5 (Hic-5) are major proteins that contribute to these events. In this study, we investigated the expression of focal adhesion proteins in the developing rat kidney. Western blotting analysis revealed that the protein levels of FAK, p-FAK(397), paxillin, p-paxillin(118), and Hic-5 were high in embryonic kidneys, while ILK expression persisted from the embryonic to the mature stage. Immunohistochemistry revealed that FAK, p-FAK(397), paxillin, and p-paxillin(118) were strongly expressed in condensed mesenchymal cells and the ureteric bud. They were detected in elongating tubules and immature glomerular cells in the nephrogenic zone. Hic-5 was predominantly expressed in mesenchymal cells as well as immature glomerular endothelial and mesangial cells, suggesting that Hic-5 might be involved in mesenchymal cell development. ILK expression was similar to that of FAK in the developmental stages. Interestingly, ILK was strongly expressed in podocytes in mature glomeruli. ILK might play a role in epithelial cell differentiation as well as kidney growth and morphogenesis. In conclusion, the temporospatially regulated expression of focal adhesion proteins during kidney development might play a role in morphogenesis and cell differentiation.

Abstract
Oesophageal cancer is one of the most aggressive tumours with a poor prognosis. However, little is known about the immune response in the tumour microenvironment. To investigate the role of immunosurveillance in the clinical course of oesophageal squamous cell carcinoma, 98 formalin-fixed, paraffin-embedded primary tumours were analysed using immunohistochemical methods for human leucocyte antigen (HLA) class I heavy chain and β2-microglobulin expression and for CD4-, CD8- and CD57-positive cell infiltration. HLA class I expression of tumour cells was correlated positively with infiltration of CD8(+) T cells into the cancer nest, but not with the clinical course of disease. However, CD8(+) and CD4(+) T cell infiltration was correlated with prognosis. These results suggest that tumour antigen-specific cellular immune response plays a role in the clinical course of the disease and that HLA class I antigen expressed on tumour cells contribute to this association most probably by mediating the interactions between tumour cells and CD8(+) T cells.

Abstract
285 Background: The aim of the present study was to determine prognostic factors in patients with metastatic pancreatic adenocarcinoma (PC) receiving systemic chemotherapy and to construct and validate a prognostic index for metastatic PC. Methods: The relationship between patient characteristics and outcome was examined by multivariate regression analyses of data from 409 consecutive patients with metastatic pancreatic adenocarcinoma who had been treated with a gemcitabine- containing regimen (GEM alone: 302 patients, GEM + cisplatin (CDDP): 39, GEM + 5-flurorouracil (5-FU): 27, GEM + S-1:41), and we stratified the patients into three risk groups according to the number of prognostic factors they had for a poor outcome. A validation data set obtained from 145 patients who had been treated with agents other than GEM (5-FU + CDDP, MTX+5- FU, docetaxel, UFT, S-1, CPT-11) was analyzed. The prognostic index was applied the each of the patients. Results: The multivariate regression analyses revealed that the presence of pain (hazard ratio (HR): 1.692), peritoneal dissemination (HR:1.756), liver metastasis (HR:1.423), and an elevated serum CRP level by > 1.0 mg/dl (HR:1.540) significantly contributed to a shorter survival time. The patients were stratified into three groups according to their number of risk factors and their outcomes of the three groups were significantly different. The median survival times (MSTs) of the low-, intermediate-, and high-risk groups were 11.1, 7.3, and 3.2 months, respectively. When the prognostic index was applied to the validation data set, the respective outcomes of the three groups were found to be significantly differed from each other. The MSTs of the low-, intermediate-, and high-risk groups were 8.6, 5.2, and 2.3 months, respectively. Conclusions: Pain, peritoneal dissemination, liver metastasis, and an elevated serum CRP value are important prognostic factors for patients with metastatic pancreatic adenocarcinoma. No significant financial relationships to disclose.

Abstract
340 Background: Gallbladder cancer (GBC) is one of the most common malignancies of the biliary tract. Because of the lack of specific presentations, this condition is frequently diagnosed only at an advanced stage. Obstructive jaundice is generally regarded as an indicator of far advanced disease, unresectability, and poor prognosis. The aim of this study was to evaluate clinicopathological factors, especially jaundice, influencing outcome after radical resection of gallbladder cancer, in order to identify the patients benefiting from radical surgery. Methods: Seventy-five patients with GBC underwent surgical resection between 1998 and 2008. A retrospective analysis was conducted on sixty-four patients with UICC T2 or more tumors. Clinicopathologic features, extents of resection, and survival rates were investigated retrospectively. Obstructive jaundice was defined that serum T-bil level was more than 2.0 mg/ml. Patients with jaundice underwent ENBD or PTBD and curative resection was performed when serum T-Bil level decreased below 2.0 mg/ml. Right after laparotomy, para-aortic lymphadenectomy and frozen section pathology were performed to convert a radical resection to a palliative procedure when a para-aortic lymph node was positive. Results: The three and five-year disease-specific survival rates were 47% and 41%, respectively. Nine patients survived for more than five years.Univariate analysis showed that blood loss during operation, hepatic invasion, portal vein invasion, N category, M category after postoperative pathological examination and residual tumor were significant prognostic factors (p<0.05), but multivariate analysis showed that M category only was independent prognostic factor (p<0.05). Five-year disease-specific survival rates for patients with (n=37) and without (n=27) obstructive jaundice were 47% and 35%, respectively (p=0.69). Conclusions: Obstructive jaundice had no impact on postoperative survival as long as metastatic disease was exclueded and adequate resection of the hepatic hilum was performed. Aggressive surgery might bring long-term survival in selected patients even with obstructive jaundice by advanced gallbladder cancer. No significant financial relationships to disclose.

Abstract
313 Background: Patients with biliary tract cancer (BTC) have a high risk of developing cholangitis. In patients with advanced BTC receiving systemic chemotherapy, cholangitis might interfere with the execution of the treatment. Furthermore, cholangitis during severe immunosuppression might develop into lethal complications such as sepsis or shock. Purpose: To determine the incidence of cholangitis among patients with advanced BTC undergoing systemic chemotherapy and to identify risk factors for the development of cholangitis. Methods: We reviewed the records of 301 patients with advanced BTC who received systemic chemotherapy at our hospital between February 2002 and July 2009. The clinical data of patients treated with gemcitabine monotherapy (GEM) as a first-line chemotherapy was retrieved. Results: One hundred and thirty-one patients were successfully followed up throughout the entire GEM treatment. Forty-three patients had intrahepatic BTC (32.8%), 28 had extrahepatic BTC (21.4%), 11 had hilar BTC (8.4%), 7 had ampullary cancer (5.3%), and 42 had gallbladder cancer (32.1%). Interventional radiological treatment or biliary reconstruction for biliary obstruction was performed in 50 patients (37.9%) prior to the start of chemotherapy. The median time to GEM treatment failure was 126 days. Cholangitis developed in 30 patients (22.9%) during GEM, and severe cholangitis developed in 10 patients (7.6%). The median time to the first episode of cholangitis from the start of chemotherapy was 65 days. Chemotherapy was discontinued because of cholangitis in 4 patients (3.1%), but no deaths as a result of cholangitis occurred. A multivariate analysis using a logistic regression model demonstrated that the presence of hilar obstruction (p=0.0002, OR: 10.748), the loss of sphincter of Oddi function (p=0.0005,OR: 8.960), and the presence of internal biliary drainage (p=0.007, OR: 4.472) were independent risk factors of cholangitis. Conclusions: The incidence of cholangitis during GEM treatment was 22.9% among the advanced BTC patients in this study. Hilar obstruction, the loss of sphincter of Oddi function, and internal biliary drainage may be risk factors of cholangitis. No significant financial relationships to disclose.

Abstract
Several DNA sequences with homology to the complete 2.9-kilobase (kb) P element from a P strain in the United States were isolated and characterized from two Drosophila melanogaster strains collected on Chichi Jima, an island 1000 km south of Tokyo. Except for a missing central region and trivial unsequenced regions of 38 base pairs, the 2.1-kb element isolated from a Q strain had the same DNA sequence as that of the complete P element. Seven other elements cloned from genomic DNAs of the Q strain and a Q-derived M strain all possessed the same restriction sites as those of the 2.9-kb P element except for one deleted region in each element. The finding of sequence conservation in P elements have had a common ancestor relatively recently. Thus, it is suggested that the P element family was a recent invader of the species. By contrast, no complete P element was found in these Japanese strains so far as surveyed, indicating the possibility that P elements in the Chichi Jima population are almost all defective. The implication of this possibility is discussed in relation to the uniqueness of the population on Chichi Jima where Q strains predominate and no P strains have yet been found.

Abstract
BACKGROUND AND PURPOSE Proteinase-activated receptor 2 (PAR(2)) is a G-protein coupled receptor associated with many pathophysiological functions. To date, the development of PAR(2) antagonists has been limited. Here, we identify a number of novel peptide-mimetic PAR(2) antagonists and demonstrate inhibitory effects on PAR(2)-mediated intracellular signalling pathways and vascular responses. EXPERIMENTAL APPROACH The peptide-mimetic compound library based on the structures of PAR(2) agonist peptides were screened for inhibition of PAR(2)-induced calcium mobilisation in human keratinocytes. Representative compounds were further evaluated by radioligand binding and inhibition of NFkappaB transcriptional activity and IL-8 production. The vascular effects of the antagonists were assessed using in vitro and in vivo models. KEY RESULTS Two compounds, K-12940 and K-14585, significantly reduced SLIGKV-induced Ca(2+) mobilisation in primary human keratinocytes. Both K-12940 and K-14585 exhibited competitive inhibition for the binding of a high-affinity radiolabelled PAR(2)-ligand, [(3)H]-2-furoyl-LIGRL-NH(2), to human PAR(2) with K(i) values of 1.94 and 0.627 microM respectively. NFkappaB reporter activity and IL-8 production were also significantly reduced. Furthermore, relaxation of rat-isolated aorta induced by SLIGRL-NH(2) was inhibited competitively by K-14585. K-14585 also significantly lowered plasma extravasation in the dorsal skin of guinea pigs and reduced salivation in mice. CONCLUSIONS AND IMPLICATIONS K-12940 and K-14585 antagonized PAR(2) competitively, resulting in inhibition of PAR(2)-mediated signalling and physiological responses both in vitro and in vivo. These peptide-mimetic PAR(2) antagonists could be useful in evaluating PAR(2)-mediated biological events and might lead to a new generation of therapeutically useful antagonists.
