Abstract
BACKGROUND The C-reactive protein : albumin ratio (CAR) has been reported as a novel prognostic marker in several cancers. The aim of this study was to investigate the prognostic value of CAR in patients with intrahepatic cholangiocarcinoma (ICC). METHODS This was a single-centre retrospective study of patients who underwent surgery for ICC in a university hospital in Japan between 1998 and 2018. CAR, Glasgow Prognostic Score (GPS) and modified GPS (mGPS) were calculated. Their correlation with recurrence-free survival (RFS) and overall survival (OS) was analysed with Cox proportional hazards models. RESULTS Seventy-two patients were included in the study. Patients were divided into two groups according to the optimal CAR cut-off value of 0·02. CAR above 0·02 was associated with higher carbohydrate antigen 19-9 levels (20·5 versus 66·1 units/ml for CAR of 0·02 or less; P = 0·002), larger tumour size (3·2 versus 4·4 cm respectively; P = 0·031) and a higher rate of microvascular invasion (9 of 28 versus 25 of 44; P = 0·041). RFS and OS were shorter in patients with CAR above 0·02: hazard ratio (HR) 4·31 (95 per cent c.i. 2·02 to 10·63) and HR 4·80 (1·85 to 16·40) respectively. In multivariable analysis CAR above 0·02 was an independent prognostic factor of RFS (HR 3·29 (1·33 to 8·12); P < 0·001), but not OS. CONCLUSIONS CAR was associated with prognosis in patients who had hepatic resection for ICC.

Abstract
BACKGROUND The right hepatic venous system consists of the right hepatic vein (RHV) and inferior RHVs (IRHVs). When the right posterior section is used as a graft for liver transplantation, understanding variations and relationships between the RHV and IRHVs is critical for graft venous return and hepatic vein reconstruction. This study aimed to evaluate variations in the hepatic veins and the relationships between them. METHODS The medical records and CT images of patients who underwent hepatectomy as liver donors were assessed retrospectively. The relationship between the veins was evaluated by three-dimensional CT. RESULTS The configuration of the posterior section was classified into one of eight types based on the RHV and IRHVs in 307 patients. Type 1a (103 of 307), type 1b (139 of 307) and type 2a (40 of 307) accounted for 91·9 per cent of the total. The diameter of the RHV extending towards the inferior vena cava had a significant inverse correlation with that of the IRHV (r2 = -0·615, P < 0·001). Type 1a, which had no IRHVs, had the RHV with the largest diameter; conversely, type 2a, which had a large IRHV, had the RHV with the smallest diameter. CONCLUSION The hepatic venous system of the right posterior section was classified into eight types, with an inverse relationship between RHV and IRHV sizes. This information is useful for segment VII resection or when the right liver is used as a transplant graft.

Abstract
Cholangitis is a major complication following transplantation. We report a living donor liver transplant (LDLT) patient with cholangitis due to multiple stones in the intrahepatic bile duct during hepaticojejunostomy anastomosis, who was successfully treated with the rendezvous technique using double balloon endoscope. A 64-year-old woman underwent LDLT with right lobe graft and hepaticojejunostomy for Wilson disease. There was bile leakage with biliary peritonitis, which was treated conservatively after transplant. Two years after surgery, she developed reiterated cholangitis due to stenosis of hepaticojejunostomy anastomosis and multiple stones in the intrahepatic bile ducts. Percutaneous transhepatic biliary drainage was performed. The size of the drainage tube was increased, and the anastomotic area was dilated in a stepwise manner using a balloon catheter. The stones were crushed and lithotomy was performed using electronic hydraulic lithotripsy through cholangioscopy. Finally, lithotomy was performed for the remaining stones through endoscopic retrograde cholangiography with the rendezvous technique using the double balloon endoscope. Rendezvous approach with percutaneous transhepatic biliary drainage and double balloon endoscopic retrograde cholangiography was an effective treatment for the multiple intrahepatic stones in hepaticojejunostomy following LDLT with right lobe graft.

Abstract
Transplant-associated thrombotic microangiopathy (TA-TMA) is a rare but severe complication after liver transplantation. In contrast to other thrombotic microangiopathies, treatment for TA-TMA has yet to be clarified. A 52-year-old male patient with liver cirrhosis due to hepatitis C underwent split liver transplantation from a deceased donor. His clinical course was without complication until 4 days after transplantation, when he experienced impaired consciousness, hemolytic anemia with fragmented erythrocytes, and marked thrombocytopenia. TA-TMA was diagnosed, and recombinant thrombomodulin was administered for 4 days. The patient's clinical symptoms and laboratory data rapidly improved. He has been followed up for 6 months and has not shown any complications. The pathogenesis of TA-TMA is endothelial damage in the vasculature. Recombinant thrombomodulin, an endothelial cell-protecting agent, is a promising new therapeutic choice for TA-TMA after liver transplantation.

Abstract
Abstract
Background: HER2 (human epidermal growth factor receptor 2) testing performed by IHC (immunohistochemical) methods and FISH (fluorescence in situ hybridization) is semi-quantitative. Exact quantification of HER2 is needed to predict which patients are more or less likely to response to anti HER2 therapy. To improve the method for cancer patients' HER2 status, we developed a novel fluorescence IHC method using new fluorescence nanoparticle. The fluorescent intensity of this new nanoparticles, termed phosphor-integrated dot (PID), was approximately 100-fold brighter than that of Quantum dots. Because of its increased brightness and analyzing technology, this PID-based fluorescent IHC(IHC-PIC) has an ability of quantifying the biomarker protein in the cancer tissue sample at single particle level. In this study, the primary objective was to investigate if pathological complete response (pCR) rate in HER2- positive breast cancer treated by trastuzumab and lapatinib containing neoadjuvant systemic therapy would depend on the level of HER2, EGFR, HER3, Ki67, ER and PgR protein quantified by this new method.
Methods: The Neo-LaTH study is a randomized phase II multicenter trial evaluating the efficacy and safety of lapatinib and trastuzumab followed by lapatinib and trastuzumab plus weekly paclitaxel with or without prolongation of anti-HER2 therapy prior to chemotherapy (18 weeks vs. 6 weeks). The primary endpoint was the comprehensive pCR rate. We evaluated the HER2, EGFR, HER3, Ki67, ER and PgR amount by nano-patho method using PID in formalin-fixed paraffin-embedded core biopsy samples taken at diagnosis retrospective analysis. Univariate and multivariate analyses were performed to determine the association between pCR and variables, including HER2, EGFR, HER3, Ki67, ER and PgR nano-patho score and clinicopathological factors including histological grade, tumor status, nodal status and HER2 FISH ratio.
Results: A total of 96 tumor samples from patients were used for the present analysis.The pCR rate was 60.4%. We obtained the images of only PID signal by the image analyses, and calculated the number of PID particles in a cell and defined it as IHC-PID score that reflects the level of HER2, EGFR, HER3, Ki67, ER and PgR protein expression in cancer cells. Univariate analysis showed that HER2 IHC-PID score(p<0.0001), ER IHC-PID score(p=0.009) and PgR IHC-PID score(p=0.019) were associated with pCR and multivariate analysis showed that HER2 IHC-PID score was significantly associated with pCR (adjusted odds ratio, 0.990 [95% CI, 0.984–0.996]; P < .0001).
Conclusion: We successfully performed the quantitative IHC-PID for HER2, EGFR, HER3, Ki67, ER and PgR. And we propose using HER2 IHC-PID score as a predictive factor for trastuzumab and lapatinib containing neoadjuvant systemic therapy. This quantitative diagnostic method would be expected to contribute to the development of a molecular therapeutic strategy.

Abstract
SummaryWe previously reported that antithrombin (AT) reduced ischemia/ reperfusion (I/R)-induced liver injury in rats by increasing endothelial production of prostacyclin (PGI2). However, the mechanism(s) underlying this phenomenon remains to be fully elucidated. We also demonstrated that activation of capsaicinsensitive sensory neurons increased endothelial production of PGI2 by releasing calcitonin gene-related peptide (CGRP) in rats subjected to hepatic I/R. In the present study, we investigated whether AT increases endothelial production of PGI2 through activation of the sensory neurons in rats subjected to hepatic I/R. AT significantly enhanced the I/R-induced increases in hepatic tissue levels of CGRP in rats. Increases in hepatic tissue levels of 6-keto-PGF1α, a stable metabolite of PGI2 , the increase in hepatic-tissue blood flow, and attenuation of both hepatic local inflammatory responses and liver injury in rats administered AT were completely reversed by administration of capsazepine, an inhibitor of sensory neuron activation and CGRP(8–37), a CGRP antagonist.AT did not show any protective effect on liver injury in animals undergoing functional denervation by administration of a large amount of capsaicin.AT significantly increased CGRP release from cultured dorsal root ganglion neurons isolated from rats in the presence of capsaicin.Taken together,these observations strongly suggested that AT might increase hepatic tissue levels of PGI2 via enhancement of hepatic I/R-induced activation of capsaicin-sensitive sensory neurons,thereby reducing liver injury in rats. In this process, CGRP-induced activation of both endothelial nitric oxide synthase and cyclooxygenase-1 might be critically involved.

Abstract
SummaryAlthough tumor necrosis factor-α (TNF-α) has been shown to play a critical role in the pathologic process leading to ischemia/reperfusion (I/R)-induced liver injury in rats by activating neutrophils, it is not clear whether or not microthrombus formation induced by TNF-α contributes to the liver injury. In the present study, we investigated the role of microthrombus formation in I/R-induced liver injury in rats. Hepatic tissue levels of TNF-α were significantly increased after reperfusion, and these were higher in animals subjected to 120 min-hepatic I/R than in those subjected to 60 min-hepatic I/R. Fibrin deposition was observed histologically in the hepatic sinusoidal space only in animals subjected to 120 min-hepatic I/R. Both the decrease in hepatic tissue blood flow and the extent of liver injury in animals subjected to 60 minand 120 min-hepatic I/R were significantly inhibited by pretreatment with anti-rat TNF-α antibody. Although neutrophil elastase inhibitors inhibited the decrease in hepatic tissue blood flow and reduced liver injury in animals subjected to 60 min-hepatic I/R, anticoagulants did not show any effects. Both anticoagulants and neutrophil elastase inhibitors inhibited the decrease in hepatic tissue blood flow and reduced liver injury in animals subjected to 120 min-hepatic I/R. Therapeutic effects of anti-rat TNF-α antibody on the120 min-I/R-induced liver injury were more marked than those of each anticoagulant or each neutrophil elastase inhibitor, and were comparable to those of combined use of anticoagulants and neutrophil elastase inhibitors. These observations strongly suggest that TNF-α induces I/R-induced liver injury primarily by activating neutrophils, and it exacerbates liver injury by inducing microthrombus formation when the production of TNF-α is further increased.

Abstract
SummaryTissue factor (TF) plays a critical role in the pathogenesis of disseminated intravascular coagulation (DIC) observed in patients with septic shock. Urinary trypsin inhibitor (UTI), a multivalent protease inhibitor, is currently used for treatment of patients with septic shock. This study was undertaken to determine whether UTI reduces LPS-induced coagulation abnormalities by inhibiting lipopolysaccharide (LPS)-induced expression of TF by monocytes. UTI inhibited LPS-induced increases in both TF activities andTF mRNA expression in monocytes without affecting the viability. Although activation of nuclear factor-κB (NF-κB), activator protein-1 (AP-1) and extracellular signal-regulated kinase (ERK)1/2 were shown to be critically involved in LPS-induced increases in TF activities in isolated monocytes, UTI inhibited phosphorylation of ERK1/2 and decreased expression of early growth response factor-1 (Egr-1) induced by LPS without affecting the activation of NF-κB and AP-1. UTI inhibited both the expression of TF mRNA in whole blood, increases in TF activities in mononuclear cells, and increases in serum levels of fibrin and fibrinogen degradation products (E) in rats given LPS without affecting the number of monocytes in the peripheral blood. Taken together these results strongly suggested that UTI might reduce LPS-induced coagulation abnormalities in rats by inhibiting TF expression in monocytes through inhibition of Egr-1 expression.

Abstract
SummaryWe recently demonstrated that antithrombin (AT) reduces ischemia/reperfusion (I/R)-induced liver injury in rats by increasing hepatic tissue levels of calcitonin gene-related peptide (CGRP),a neuropeptide released from the sensory nerve endings. In the present study, we examined the effect of AT on I/Rinduced liver injury in wild type mice (CGRP+/+) and congenitally αCGRP-deficient mice (CGRP−/−). We also investigated any effects of AT on CGRP release from dorsal root ganglion neurons (DRG) isolated from CGRP+/+. Based on results obtained in the present study, we attempted to determine if the anti-inflammatory activity of AT in vivo is dependent mainly on sensory neuron activation. AT enhanced ischemia/reperfusion-induced increases in hepatic tissue levels of CGRP and 6-keto-PGF1α
, a stable metabolite of PGI2, in CGRP+/+, but it did not enhance these increases in CGRP−/−. AT inhibited reperfusion-induced increases in serum alanine aminotransferase levels by increasing hepatic tissue blood flow and by attenuating increases in hepatic levels of tumor necrosis factor and myeloperoxidase in CGRP+/+,although it showed neither of these therapeutic effects in CGRP−/−. AT increased CGRP release from cultured DRGs only in the presence of anandamide, and AT-induced increase in CGRP release was not observed in the presence KT5720, an inhibitor of protein kinase A (PKA).AT markedly increased intracellular levels of cAMP in the presence of anandamide. These results strongly suggest that AT might reduce I/R-induced liver injury by enhancing activation of the sensory neurons through activation of PKA in sensory neurons.

Abstract
SummaryThis study was conducted to determine which isoform of cyclooxygenase (COX) is more significantly involved in the antithrombin (AT)-induced increase in prostaglandin production in the liver of rats, subjected to hepatic ischemia/reperfusion (I/R). Hepatic tissue levels of 6-keto-PGF1α, a stable metabolite of prostacyclin (PGI2), and PGE2 were transiently increased 1 hour after reperfusion. Thereafter, hepatic PGE2 levels were gradually increased until 6 hours after reperfusion, while hepatic 6-keto-PGF1α levels were decreased to the pre-ischemia levels at 6 hours after reperfusion. AT significantly enhanced increases in hepatic tissue levels of 6-keto-PGF1α and PGE2 seen 1 hour after reperfusion, while it inhibited increases in hepatic PGE2 levels seen 6 h after reperfusion. Neither dansyl-Glu-Gly-Arg-chloromethyl ketone-treated factor Xa (DEGR-Xa), a selective inhibitor of thrombin generation, nor Trp49-modified AT which lacks affinity for heparin, showed any effects on these changes. Pretreatment with indomethacin (IM), a non-selective inhibitor of COX, inhibited AT-induced increases in hepatic tissue levels of 6-keto-PGF1α and PGE2 seen 1 hour after reperfusion, whereas pretreatment with NS-398, a selective inhibitor of COX-2, did not. The increase in hepatic tissue blood flow and inhibition of hepatic inflammatory responses seen in animals given AT were reversed by pretreatment with IM, but were not affected by pretreatment with NS-398. Administration of iloprost, a stable analog of PGI2, and PGE2 produced effects similar to those induced by AT. Increases in hepatic tissue levels of PGE2 6 hours after reperfusion were inhibited by pretreatment with NS-398. Although AT did not affect COX-1 mRNA levels 1 hour after reperfusion, it inhibited the I/R-induced increases in hepatic tissue levels of both PGE2 and COX-2 mRNA 6 hours after reperfusion. These observations strongly suggested that AT might reduce the I/R-induced liver injury by increasing the production of PGI2 and PGE2 through activation of COX-1. Furthermore, since TNF-a is capable of inducing COX-2, inhibition of TNF-a production by AT might inhibit COX-2-mediated PGE2 production. These effects induced by AT might contribute to its anti-inflammatory activity.

Abstract
SummaryThis study was undertaken to examine the mechanism by which danaparoid sodium (DS), a heparinoid that contains mainly heparan sulfate, prevents reperfusion-induced hepatic damage in a rat model of ischemia/reperfusion (I/R)-induced liver injury. Administration of DS significantly reduced liver injury and inhibited the decrease in hepatic tissue blood flow in rats. DS attenuated hepatic I/R-induced increases in hepatic tissue levels of tumor necrosis factor (TNF) and myeloperoxidase (MPO) in vivo. In contrast, neither monocytic TNF production nor neutrophil activation was inhibited by DS in vitro. DS enhanced I/R-induced increases in levels of calcitonin-gene related peptide (CGRP), a neuropeptide released from sensory neurons, and of 6-ketoprostaglandin (PG) F1α, a stable metabolite of PGI2, in liver tissues. The therapeutic effects of DS were not seen in animals pretreated with capsazepine, an inhibitor of sensory neuron activation. The distribution of heparan sulfate in the perivascular area was significantly increased by DS administration in this rat model. DS significantly increased CGRP release from isolated rat dorsal root ganglion neurons (DRG) in vitro, while DX-9065a, a selective inhibitor of activated factor X, did not. DS enhanced anandamide-induced CGRP release from DRG in vitro. These observations strongly suggested that DS might reduce I/R-induced liver injury in rats by attenuating inflammatory responses. These therapeutic effects of DS might be at least partly explained by its enhancement of sensory neuron activation, leading to the increase the endothelial production of PGI2.

Abstract
Although Roux-en Y hepaticojejunostomy was previously recommended for the biliary reconstruction in liver transplantation for primary sclerosing cholangitis (PSC), some recent reports showed no difference in the graft survival between Roux-en Y and duct-to-duct anastomosis in deceased-donor liver transplantation. On the other hand, considering the risk of recurrence and the short length of the bile duct of the graft, duct-to-duct biliary anastomosis has never been reported in a patient undergoing living-donor liver transplantation (LDLT) for PSC. A 45 year-old male underwent LDLT using a left-lobe graft donated from his brother. Cholangiography showed no lesion in his common bile duct and duct-to-duct anastomosis was chosen for him. Fifteen months later, he suffered cholangitis due to PSC recurrence and endoscopic retrograde cholangiography was performed. The stents were inserted into his B2 and B3, and he remains well. Because of the ability to easily manage biliary complication, duct-to-duct biliary reconstruction may become the first choice in LDLT for PSC without common bile duct lesions.

Abstract
Large-for-size syndrome (LFSS) is controversial in pediatric living donor liver transplantation patients and is associated with a poor graft outcome. Similar situations in deceased donor liver transplantation (DDLT) in adults have not been reported frequently, and there are no official guidelines worldwide. Deceased donation is extremely limited in Japan, and when a larger liver is allocated for a very sick small recipient in Japan, transplantation with a plan to address LFSS might be necessary. The patient is a 58-year-old female patient who had acute liver failure with coma. The graft-recipient weight ratio (GRWR) was 2.74%. Although the graft was enlarged by reperfusion, the intraoperative Doppler ultrasound, performed after reperfusion, showed sufficient graft in-flow and out-flow. However, when the liver graft was situated appropriately into the right phrenic space supported by the rib cage and diaphragm, the blood flow in the hepatic vein and portal vein was significantly reduced. Graft blood flow did not improve without removing it from the right subphrenic space. Therefore, we decided to perform an in situ graft posterior segmentectomy, so that the graft right lobe was properly accommodated in the patient's right subphrenic space. After the segmentectomy of the graft, an intraoperative Doppler sonogram showed significantly improved blood flow. LFSS could be a significant operative challenge in adult DDLT, especially in areas with limited chances of DDLT. In situ posterior segmentectomy in the demarcated area could be a solution for treating patients with LFSS.

Abstract
Reconstruction of multiple venous orifices of a right lobe graft is a time-consuming and troublesome procedure in right lobe living-donor liver transplantation. In the current study, we present a new venous reconstruction technique for a right lobe graft with multiple and complex hepatic vein (HV) orifices, in which procurement of the recipient's left portal vein was performed in situ to keep the anhepatic period to a minimum. All of the HV orifices were reconstructed together at the back table, while maintaining patency of the recipient's systemic and splanchnic circulation. A homologous vein graft and veno-venous bypass were not necessary. All HVs were patent during the follow-up and the patient was free from complications. In conclusion, the present technique is readily available for reconstruction of complex and multiple HV tributaries, while avoiding a long anhepatic time and the use of veno-venous bypass.

Abstract
BACKGROUND The Fukushima Daiichi and Daini Nuclear Power Plant workers experienced multiple stressors as both victims and onsite workers after the 2011 Great East Japan Earthquake and subsequent nuclear accidents. Previous studies found that disaster-related exposures, including discrimination/slurs, were associated with their mental health. Their long-term impact has yet to be investigated. METHOD A total of 968 plant workers (Daiichi, n = 571; Daini, n = 397) completed self-written questionnaires 2-3 months (time 1) and 14-15 months (time 2) after the disaster (response rate 55.0%). Sociodemographics, disaster-related experiences, and peritraumatic distress were assessed at time 1. At time 1 and time 2, general psychological distress (GPD) and post-traumatic stress response (PTSR) were measured, respectively, using the K6 scale and Impact of Event Scale Revised. We examined multivariate covariates of time 2 GPD and PTSR, adjusting for autocorrelations in the hierarchical multiple regression analyses. RESULTS Higher GPD at time 2 was predicted by higher GPD at time 1 (β = 0.491, p < 0.001) and discrimination/slurs experiences at time 1 (β = 0.065, p = 0.025, adjusted R 2 = 0.24). Higher PTSR at time 2 was predicted with higher PTSR at time 1 (β = 0.548, p < 0.001), higher age (β = 0.085, p = 0.005), and discrimination/slurs experiences at time 1 (β = 0.079, p = 0.003, adjusted R 2 = 0.36). CONCLUSIONS Higher GPD at time 2 was predicted by higher GPD and discrimination/slurs experience at time 1. Higher PTSR at time 2 was predicted by higher PTSR, higher age, and discrimination/slurs experience at time 1.

Abstract
INTRODUCTION Immune-mediated graft dysfunction (IGD), a recently established disease entity with unfavourable outcome, is an antigraft immune reaction during interferon-based antiviral treatment for hepatitis C virus (HCV) infection after liver transplantation (LT). We report a case having steroid-resistant acute cellular rejection (ACR) type IGD, which was successfully treated using thymoglobulin. CASE REPORT A 56-year-old woman with recurrent HCV after LT was commenced on antiviral treatment including simeprevir, pegylated-interferon (IFN) 2a, and ribavirin. A negative serum HCV-RNA was confirmed after 4 weeks. After 12 weeks of therapy, severe liver dysfunction developed, despite a constantly negative HCV-RNA. Liver biopsy revealed portal and periportal inflammatory infiltrates including numerous eosinophils, lymphocytes, and bile duct damages, indicating ACR. IFN therapy was ceased, and she was treated with steroid pulse treatment, followed by high-level immunosuppression maintenance. However, ACR was irremediable. Thereafter she was treated with thymoglobulin (75 mg/d for 5 days). Her serum alanine aminotransaminase and total bilirubin levels decreased immediately, and her liver biopsy specimen showed no activity. During these periods of the treatment, the HCV-RNA became positive and the liver enzyme elevated, but other liver function tests still remained within normal range. CONCLUSION Thymoglobulin could be the best choice in steroid-resistant IGD during antiviral treatment for post-transplantation recurrent hepatitis C.

Abstract
BACKGROUND Hepatitis C viral graft reinfection is almost a universal event after liver transplantation with consequent disease progression. METHODS We applied triple therapy (n = 21) with the use of telaprevir (TVR; n = 12) or simeprevir (SVR; n = 9). RESULTS TVR was given at the dose 1,500 mg daily (n = 11) with reduced dose of cyclosporine at 25% to 50%, and SVR was given at the dose 100 mg daily with unadjusted cyclosporine, followed by 12 weeks of dual therapy. The early viral response was achieved in 91.7% (n = 11), end of treatment response rate was 91.7% (n = 11), and sustained viral response rate was 83.3% (n = 10) in the TVR group, and respective rates were 88.9% (n = 8), 77.8% (n = 7), and 77.8% (n = 7) in the SVR group. Although granulocyte colony-stimulating factor was not given in the patients with triple therapy, blood transfusion was performed in 7 cases (58.3%) in the TVR group and 1 case (11.1%) in the SVR group. Interferon-mediated graft dysfunction was observed in 4 cases (33.3%) in the TVR group and 3 cases (33.3%) in the SVR group, respectively. The cumulative viral clearance rates in triple (n = 21) and dual (n = 105) therapy were 95.0% and 18.1% at 12 weeks, and 95.0% and 40.0%, respectively, at 24 weeks (P < .01). CONCLUSIONS Although careful monitoring for possible adverse events is required during treatment, triple therapy with the use of direct-acting agents are very effective in treating hepatitis C after liver transplantation.

Abstract
Triple therapy with telaprevir, pegylated interferon and ribavirin has been reported to improve antiviral efficacy but have potentially severe adverse effects in patients with chronic hepatitis C. To avoid the severe effects of telaprevir, lowering the dose has been suggested. However, impact of dosage changes on antiviral and adverse effects remains unclear. One hundred and sixty-six Japanese patients with HCV genotype 1 were treated with triple therapy. The drug exposure of each medication was calculated by averaging the dose actually taken. The overall SVR rate was 82%. The telaprevir discontinuation rate was 26%. The factors associated with discontinuation were an older age (≥65 y.o.) and a higher average dose during treatment. The telaprevir discontinuation rates were 42%, 25% and 14% in patients at ≥35, 25-35 and <25 mg/kg/day of telaprevir and 58% in older patients at ≥35 mg/kg/day of TVR. The factors associated with SVR were treatment-naïve, relapse to previous treatment, higher average telaprevir dose during treatment and completion of treatment. The SVR rate was higher, at 91%, in patients at 25-35 mg/kg/day of telaprevir than the 71% and 78% observed in those at <25 and ≥35 mg/kg/day of drug. In Japanese patients, a mean telaprevir dose of 25-35 mg/kg/day during treatment can augment its efficacy in triple therapy for patients with HCV genotype 1.

Abstract
Pegylated interferon (Peg-IFN) plus ribavirin combination therapy is effective in patients with hepatitis C virus (HCV) infection and normal alanine aminotransferase levels (NALT). However, it remains unclear whether the risk of hepatocellular carcinoma (HCC) incidence is actually reduced in virological responders. In this study, HCC incidence was examined for 809 patients with NALT (ALT ≤ 40 IU/mL) treated with Peg-IFN alpha-2b and ribavirin for a mean observation period of 36.2 ± 16.5 months. The risk factors for HCC incidence were analysed by Kaplan-Meier method and Cox proportional hazards model. On multivariate analysis among NALT patients, the risk of HCC incidence was significantly reduced in patients with sustained virological response (SVR) or relapse compared with those showing nonresponse (NR) (SVR vs NR, hazard ratio (HR): 0.16, P = 0.009, relapse vs NR, HR: 0.11, P = 0.037). Other risk factors were older age (≥65 years vs <60 years, HR: 6.0, P = 0.032, 60-64 vs <60 years, HR: 3.2, P = 0.212) and male gender (HR: 3.9, P = 0.031). Among 176 patients with PNALT (ALT ≤ 30 IU/mL), only one patient developed HCC and no significant risk factors associated with HCC development were found. In conclusion, antiviral therapy for NALT patients with HCV infection can lower the HCC incidence in responders, particularly for aged and male patients. The indication of antiviral therapy for PNALT (ALT ≤ 30 IU/mL) patients should be carefully determined.

Abstract
OBJECTIVES The aim of this study was to analyse the position and relationship of juxta-apical radiolucency (JAR) to the mandibular canal and buccal and/or lingual cortical plates using cone beam CT (CBCT). METHODS A retrospective study was carried out to analyse the JAR on CBCT for 27 patients. These findings were compared with 27 age- and sex-matched patients without the presence of JAR, which acted as the control group. The CBCT images were analysed according to a checklist, to evaluate the position of the JAR and its relationship to the mandibular canal. Then, any thinning or perforation of either the buccal or lingual cortical plate due to JAR was noted, and a classification to quantify the thinning of cortical plates was proposed. The findings in the two groups were analysed using a paired comparison by McNemar test. RESULTS A statistical increased thinning of cortical plates was seen in the JAR group compared with the control group, and most of the cases were in the J3 group. None of the patients in either the JAR or the control group showed perforation of the buccal and/or lingual cortical plate on CBCT images. CONCLUSIONS A classification to quantify the thinning of cortical plates was proposed, which may be used for objective evaluation of the thinning of the cortical plates in future studies. The present study gives an insight into the relationship of the juxta-apical area with the mandibular canal and cortical plates in the mandible using CBCT.

Abstract
AIM The aim of this paper was to investigate the effects of the whole-body vibration (WBV) intervention on neuromuscular performances in both young and elderly healthy subjects, taking into consideration the recommendations of the international standard for such exposure. METHODS Two groups of healthy subjects (9 young and 18 elderly) received the intervention while standing on a side-alternating platform, during two exposure periods of 8 weeks each separated by a washout period of 8 weeks between those periods. The intervention (with or without exposure to vibration) was administered twice a week. Vibration was produced at 20 Hz with an unweighted acceleration of 11.2 m/s2 rms in the first 4 weeks, and 22.3 m/s2 rms, in the last 4 weeks. Blood pressure, heart rate, single leg stance time with closed eyes (SSCE), postural stability parameters and knee joint position sense were measured before and after intervention and were compared. RESULTS In the young group, the post-intervention measurement values did not differ from the corresponding pre-intervention values. In the elderly group, SSCE at the right side significantly increased (P<0.014) after vibration intervention. The lateral sway (X-axis locus length) of postural stability parameter after WBV intervention tended to decrease in the elderly group (P=0.078). However, in both groups, pre- and post-intervention values of knee joint position sense were not significantly different. CONCLUSION The used level of vibration showed some improvements in postural balance among the elderly. However, an effective level of vibration exposure should be decided for this purpose, considering the recommendations of the relevant standards.

Abstract
Abstract
Background;
Glycolysis is one of the major metabolic pathways in cancer cells. The conversion of glucose to lactate in the presence of oxygen is a critical aerobic pathway that allows cancer cells to proliferate rapidly and the amount of lactate produced is correlated with tumor aggressiveness. Moreover, the increase in glycolysis is partially mediated by hypoxia-inducible transcription factor (HIF-1) and a metabolic enzyme, lactate dehydrogenase B (LDHB). However, the mechanism behind this metabolic shift is not well understood. Metformin reduces the overall risk of cancer incidence by 31%, improves cancer-related mortality and enhances response to chemotherapy in diabetic patients pre-operatively. This study aimed to evaluate metabolism in triple negative breast cancer.
Methods;
Breast cancer cell lines (estrogen receptor positive MCF7 and triple negative MDA-MB 231 and MDA-MB468) were analysed for protein expression by western blotting and mRNA expression by qRT-PCR with or without cisplatin and metformin. To study the biological mechanism, we evaluated cell growth using proliferation assay in the presence of metformin and cisplatin. The contribution of LDHB to glycolysis was evaluated using MDA-MB-231 and MDA-MB468 cell lines.
Results;
We first examined the basal expression levels of LDHB and HIF1a in these cancer cell lines. LDHB expression was high in MDA-MB 231, and HIF1α was high in MDA-MB468. Both metformin and cisplatin treatment resulted in the down-regulation of LDHB and HIF1α in MDA-MB231, metformin led to downregulation of LDHB in MDA-MB 468, while MCF7 demonstrated no significant changes. Inhibition of cell proliferation was dose-dependent and significant at low concentrations of cisplatin and metformin in only MDA-MB468 but not in MCF7 and MDA-MB231. The combination of cisplatin in with metformin had an added inhibitory effect on cell proliferation in these MD-MB231 cells.
Conclusion;
These studies suggest that combination treatment of metformin and cisplatin have potent anticancer activity in LDHB highly expressed triple negative breast cancer cells. Identification of a new targeted therapeutic approach could contribute to the new therapy to the breast cancer patients.

Abstract
Abstract
Background:
Triple negative breast cancer (TNBC) has been associated with a high glycolytic rate. As a surrogate measure, the SUV of FDG uptake is found to be higher both in the TNBC and her2 positive phenotypes. Tumour lesion glycolysis (TLG) is a product of the mean SUV value and tumour volume. We wished to evaluate the role of combined volume and metabolic measurements of glycolysis in patients with TNBC.
Methods: 300 FDG-PET scans were performed in patients with breast cancer, of whom 25 were found to have TNBC over a 4 year period, in 19 patients there were suitable lesions identified for analysis. Patients were scanned on the same Siemens PET/CT scanner in the local hospital, static images were acquired 60 minutes post-injection. SUV was corrected for injected activity and body weight, TLGMAX50 was also calculated considering SUV50 isocontour instead of SUV mean. ∑TLG was the sum of TLG for an individual patient.
Results: 117 lesions in total from 19 different patients were analyzed (mean = 6.15 lesions per patient). SUVMEAN, TLG mean, SUVMAX and TLGMAX were calculated for each lesion. SUVMEAN per patient varied from 2.69 to 15.48 while SUV50 varied from 5.45 to 48.23. ∑TLGMEAN and ∑TLGMAX ranged from 13.06 to 364.072 and 18.29 to 575.627, respectively. There was significant variation between patients and within different tumor lesions within patients. SUVPEAK for all lesions of patients ranged from 4.8 to 36.4.
Conclusions: TLG varies widely in patients with triple negative breast cancer, further studies are required to determine if this will be a useful prognostic/predictive measure in the future.

Abstract
Neutropenia during chemotherapy has been reported to be a predictor of better survival in patients with several types of cancer, although there are no reports on stage III colorectal cancer (CRC). The purpose of this study was to examine the association between neutropenia and prognosis in stage III CRC patients receiving adjuvant chemotherapy consisting of oral uracil and tegafur (UFT) plus leucovorin (LV). We retrospectively analysed 123 patients with stage III CRC who received UFT/LV as adjuvant chemotherapy. The end-point was disease-free survival (DFS). Survival curves of the two categories (neutropenia absent vs. present) were estimated using the Kaplan-Meier method and compared by the log-rank test. We estimated the hazard ratio (HR) for DFS according to neutropenia after adjustment for covariates by multivariate analyses using Cox's regression analysis. A total of 33 (26.8%) patients experienced neutropenia. Patients without neutropenia showed a significantly lower DFS than those with neutropenia (3-year DFS 57.3% vs. 81.2%, P = 0.0213). By multivariate analysis, neutropenia and histological type were independent prognostic factors, with HR of 0.410 (neutropenia absent vs. present, P = 0.045) and 4.793 (well to moderately differentiated vs. poorly differentiated, P = 0.004) respectively. We demonstrated that neutropenia occurring during adjuvant chemotherapy consisting of UFT/LV may be a prognostic factor of recurrence in stage III CRC patients.

Abstract
OBJECTIVES Primary hyperparathyroidism (PHPT), affecting 1% of the population, is associated with increased cardiovascular morbidity and mortality. The presence of calcified carotid artery plaque (CCAP) on panoramic images is a validated risk indicator of future adverse cardiovascular events. We hypothesized that military veterans aged 50 years or older diagnosed with PHPT by increased parathyroid hormone and calcium levels would frequently have CCAP on their images. METHODS We determined the prevalence rates of CCAP on the images of patients diagnosed with PHPT and evaluated their atherogenic risk profiles, including hypertension, dyslipidaemia, diabetes and obesity. Comparisons of atherogenic risk factors were made between subjects with and without observed CCAP on their panoramic images. RESULTS Of the 60 patients (86.7% males and 13.3% females, mean age 73.2 ± 11.3 years) with PHPT, 40% had atheromas. There were no significant differences between CCAP+ and CCAP- groups in gender or race (p > 0.05). The atherogenic profile (age, body mass index, hypertension, diabetes, hyperlipidaemia) in the CCAP+ and CCAP- groups was not significantly different (p > 0.05). CONCLUSIONS Calcified carotid artery atheromas are often seen on the panoramic images of patients with PHPT. Thus, dentists must be uniquely vigilant for these lesions when evaluating these studies.

Abstract
Replacing the thoracic esophagus with the colon is one mode of reconstruction after esophagectomy for esophageal cancer. There is, however, a high incidence of postoperative necrosis of the transposed colon. This study evaluated the outcomes of colon interposition with the routine use of superdrainage by microvascular surgery. Twenty-one patients underwent colon interposition from 2004 to 2009. The strategy for colon interposition was to: (i) use the right hemicolon; (ii) reconstruct via the subcutaneous route; (iii) perform a microvascular venous anastomosis for all patients; and (iv) perform a microvascular arterial anastomosis when the arterial blood flow was insufficient. The clinicopathologic features, surgical findings, and outcomes were investigated. The colon was used because of a previous gastrectomy in 18 patients (85.7%) and synchronous gastric cancer in three patients (14.3%). Eight patients (38.1%) underwent preoperative chemoradiotherapy including three (14.3%) treated with definitive chemoradiotherapy. Seven patients (33.3%) underwent microvascular arterial anastomosis to supplement the right colon blood supply. Pneumonia occurred in four patients (19.0%). Anastomotic leakage was observed in five patients (23.8%); however, no colon necrosis was observed. The 3-year and 5-year overall survival rates were both 50.6%. Colon interposition with superdrainage results in successful treatment outcomes. This technique is one option for colon interposition employing the right hemicolon.

Abstract
Neurosteroidal oestrogen has been proposed to play important roles in a variety of reproductive behaviours. Aromatase, a key enzyme in oestrogen synthesis, is localised in neural nuclei of specific brain regions and is developmentally regulated, with a transient expression peak at the perinatal period. The brain-specific promoter of the aromatase gene was analysed aiming to determine the transcriptional control mechanisms that could help explain the spatiotemporal expression. We previously reported that a 202-bp sequence, which is upstream from the transcriptional initiation site, is essential for the basal transcriptional activity. The 202-bp upstream region of brain-specific exon 1 comprises at least three types of cis-acting elements: aro-AI (Arom-Aα), aro-AII (Arom-Aβ) and aro-B (Arom-B). To identify the binding proteins for the cis-acting elements, a yeast one-hybrid screen was performed with these cis-element sequences using a mouse foetal cDNA library. Lhx2, a LIM-homeodomain protein, was identified as one of the aro-B binding proteins. The identification was further confirmed using the gel shift assay, which demonstrated binding competition of nuclear proteins to the aro-B element with a typical Lhx2-binding element. In addition, a chromatin immunoprecipitation assay with an anti-Lhx2 antibody demonstrated that Lhx2 bound to the aro-B site in vivo. A reporter assay of the brain-specific promoter demonstrated increased Lhx2-dependent promoter activity. Furthermore, the time-dependent increase in aromatase mRNA in primary cultured foetal neurones was suppressed by an small-interfering RNA-mediated knockdown of Lhx2 expression. These results show that Lhx2 is involved in the transcriptional regulation of aromatase in the rodent brain.
