Abstract
Hepatitis B virus (HBV) is a DNA virus with a complex life cycle that includes a reverse transcription step. HBV is poorly sensed by the immune system and frequently establishes persistent infection that can cause chronic infection, the leading cause of liver cancer and cirrhosis worldwide. Recent mounting evidence has indicated the growing importance of RNA methylation (m6A modification) in viral replication, immune escape, and carcinogenesis. The value of m6A RNA modification for the prediction and clinical management of chronic HBV infection remains to be assessed. However, a number of studies indicate the important role of m6A-marked transcripts and factors of m6A machinery in managing HBV-related pathologies. In this review, we discuss the fundamental and potential clinical impact of m6A modifications on HBV infection and pathogenesis, as well as highlight the important molecular techniques and tools that can be used for studying RNA m6A methylome.

Abstract
Hepatitis B virus (HBV) infection is a major public health problem worldwide. The study aimed to evaluate the efficacy of pegylated interferon (Peg-IFN) alfa-2a treatment for seroclearance of HBs antigen (HBsAg) in HBe antigen (HBeAg)-negative chronic hepatitis B (CHB) patients. This retrospective study investigated 16 HBeAg-negative CHB patients who received Peg-IFN alfa-2a weekly for 48 weeks. Thereafter, the patients were followed-up for 48 weeks after the end of therapy. The following criteria were also used for inclusion: HBV-DNA < 5.0 log copies/mL and without nucleot(s)ide analogs. Four HBsAg-positive cases became HBsAg negative. The HBsAg levels of the 4 patients who achieved HBsAg seroclearance were lower significantly than that of the non-seroclearance group (p = 0.007). The mean HBsAg levels in these 4 cases were 68 IU/mL, while the mean HBsAg levels in the non-seroclearance group were 2,114 IU/mL. The mean HBV-DNA levels in the 4 HBsAg seroclearance cases were 2.8 log copies/mL as compared to 3.6 log copies/mL in HBsAg-non-seroclearance cases (p = 0.01). Cases that are HBeAg negative, with HBV-DNA levels < 5 log copies/mL, and HBsAg titers < 120 IU/mL cases may achieve HBsAg clearance with Peg-IFN therapy.

Abstract
In individuals infected with hepatitis B virus (HBV), the loss of hepatitis B surface antigen (HBsAg) is the ultimate therapeutic goal, which defines "functional cure." For individuals living with human immunodeficiency virus (HIV), functional cure occurs roughly 2 per 100 person-years during potent anti-HBV containing antiretroviral therapy. Although this rate may be higher than expected in treated HBV mono-infected individuals, rates of functional cure widely vary between studies (0.6-10.5 per 100 person-years). Similar to HBV mono-infection, the phase of HBV infection, HBV (sub-)genotypes and hepatitis B "e" Ag-negative variants are associated with functional cure in treated HIV-HBV co-infection. In specifically HIV-HBV co-infected individuals, strong increases in CD4+ T cell counts after treatment initiation have also been linked to functional cure, yet this finding is inconsistent across studies. Several markers directly or indirectly reflecting HBV activity are being developed to predict functional cure, such as quantification of HBsAg, hepatitis B core-related antigen, HBsAg protein composition, anti-hepatitis B core antibodies and interferon-gamma-inducible protein 10. Few have been assessed during treatment in HIV-HBV co-infected individuals and none have been validated to predict functional cure. Novel therapeutics for HBV cure are essential for individuals with HIV-HBV co-infection and need to be separately evaluated in this population.

Abstract
BACKGROUND The main etiologies of hepatocellular carcinoma (HCC) were often hepatitis B virus (HBV) or C and alcohol, rarely autoimmune and biliary diseases. Nonalcoholic fatty liver disease (NAFLD) has been an emerging role that could lead to chronic liver disease, nonalcoholic steatohepatitis, cirrhosis, and eventually HCC in recent years. The aim of our study is to investigate and compare the clinical features of HCC in patients with NAFLD and HBV, including age, gender, cirrhosis, liver function tests, largest tumor size, and cancer stage at the time of diagnosis. The survival outcome was compared between the two groups and the significant predictors of mortality were also analyzed in all patients with HCC. METHODS Most patients with HCC were recruited from the database of Cancer Registries in Taipei City Hospital, Ren-Ai Branch, from 2011 to 2017; and the other patients consecutively from the HCC multidisciplinary conference between January 2018 and December 2019. NAFLD was defined as nonviral hepatitis B (negative HBsAg and either positive anti-HBs or negative anti-HBc), nonviral hepatitis C (negative antihepatitis C virus [HCV]), nonalcoholic (alcohol consumption of <30 g/d for men and <20 g/d for women) liver disease, or present or past histological or ultrasonographic evidence of fatty liver. Totally, 23 NAFLD-related and 156 HBV-related HCC patients were enrolled in our study for further analysis. RESULTS NAFLD-related HCC patients were significantly older (median age: 70.0 [61.0-79.0] years vs. 63.0 [56.0-72.0] years, p = 0.012) and heavier (median body mass index [BMI]: 26.6 [24.2-30] kg/m2 vs. 24.8 [22.0-27.1] kg/m2, p = 0.044) than those with HBV-related HCC. They were also more susceptible to diabetes mellitus (DM), and 60.9% (14 of 23) of them had this comorbidity compared with 29.5% (46 of 156) of those with HBV-related HCC (p = 0.003). Only 34.8% (8 of 23) and 71.2% (111 of 156) of patients with NAFLD- and HBV-related HCC were cirrhotic, respectively (p = 0.001). However, gender, tobacco use, international normalized ratio, albumin, creatinine, and cholesterol levels were not significantly different between the two groups. Tumor characteristics such as the Barcelona clinic liver cancer stage, largest tumor size, tumor number, extrahepatic metastasis, and treatment modalities had no significant difference between such groups.According to the Kaplan-Meier method analysis, the overall survival was not significantly different between these two patient groups (log-rank test, p = 0.101). To evaluate which patient group would lead to poor prognosis, we analyzed the survival of all patients through multivariate Cox proportional hazard regression after controlling other factors that may influence the hazard ratio. The analysis revealed that NAFLD and HBV infection as the cause of HCC are not risk factors of poor prognosis. CONCLUSION In conclusion, our study showed NAFLD-related HCC patients were older, heavier, and more had DM than HBV-related. In addition, more NAFLD-related HCC patients were noncirrhotic than HBV-related. The survival rate was similar between NAFLD and HBV-related HCC patients.

Abstract
Human hepatitis B virus (HBV) infection remains a serious health problem worldwide. However, the mechanism for the maintenance of HBV in a latent state within host cells remains unclear. Here, using single-cell RNA sequencing analysis, we identified four genes linked to the maintenance of HBV in a liver cell line expressing HBV RNA at a low frequency. These genes included DOCK11 and DENND2A, which encode small GTPase regulators. In primary human hepatocytes infected with HBV, knockdown of these two genes decreased the amount of both HBV DNA and covalently closed circular DNA to below the limit of detection. Our findings reveal a role for DOCK11 and DENND2A in the maintenance of HBV.

Abstract
Hepatitis B virus (HBV), an enveloped partially double-stranded DNA virus, is a widespread human pathogen responsible for more than 250 million chronic infections worldwide. Current therapeutic strategies cannot eradicate HBV due to the persistence of the viral genome in a special DNA structure (covalently closed circular DNA, cccDNA). The identification of sodium taurocholate co-transporting polypeptide (NTCP) as an entry receptor for both HBV and its satellite virus hepatitis delta virus (HDV) has led to great advances in our understanding of the life cycle of HBV, including the early steps of infection in particular. However, the mechanisms of HBV internalization and the host factors involved in this uptake remain unclear. Improvements in our understanding of HBV entry would facilitate the design of new therapeutic approaches targeting this stage and preventing the de novo infection of naïve hepatocytes. In this review, we provide an overview of current knowledge about the process of HBV internalization into cells.

Abstract
Background Because of their similar modes of transmission, the simultaneous infection of viral hepatitis and human immunodeficiency virus are increasingly seen as a big problem related to human health. Aims To determine the drug mutations in hepatitis B virus and/or hepatitis C virus co-infected human immunodeficiency virus-1 patients in Turkey. Study Design Retrospective cross-sectional study. Methods The present study was conducted between 2010 and 2017. HBsAg, anti-hepatitis C virus, and anti-human immunodeficiency virus were tested with ELISA. All anti-human immunodeficiency virus positive results by ELISA were verified for anti-human immunodeficiency virus positivity by a Western blot test, and Anti-human immunodeficiency virus positive patients with HBsAg and/or anti-hepatitis C virus positivity were included in the study. Subtyping and genotypic resistance analyses were performed by population sequencing of the viral protease and reverse transcriptase regions of the human immunodeficiency virus-1 pol gene. Results We detected 3896 human immunodeficiency virus-1 positive patients whose sera were sent from numerous hospitals across the country to our polymerase chain reaction unit for detection of drug resistance mutations and whose molecular laboratory tests were completed. Viral hepatitis co-infections were detected in 4.3% (n=170) of patients. Hepatitis B virus and hepatitis C virus co-infection were observed in 3.2% and 0.5% of all human immunodeficiency virus-1 infected patients, respectively. The major human immunodeficiency virus-1 subtype detected was group M, subtype B (62.9%). However, 13.5% of drug resistance mutation motifs were found in human immunodeficiency virus-1 genomes of patients included in the study. Conclusion Due to similar transmission routes, HIV1 patients are at risk of hepatitis B and C virus co-infection. However, antiretroviral drug resistance mutation model is similar to patients with hepatitis negative.

Abstract
Immunosuppression can lead to hepatitis B virus (HBV) reactivation in hepatitis B core antigen antibodies (anti-HBc) positive patients, especially those undergoing chemotherapy, although there is limited data on solid organ recipients, especially lung transplantation. Our aim was to analyze the risk of HBV reactivation and the potential impact of anti-HBc-positive status (both donors and recipients) on prognosis in a lung, kidney, and liver transplantation cohort.Retrospective analysis including data from all transplants in adults (2011-2012) in a tertiary hospital, with prospective HBV serology study to assess the risk of reactivation and its possible impact on survival.In total, 392 transplant recipients were included (196 kidney, 113 lung, 83 liver). Pre-transplantation anti-HBc screening was more frequent in liver recipients (P < .001) and donors (P < .001) than in kidney or lung. Fifty-five (14%) recipients were anti-HBc-positive and were not undergoing antiviral prophylaxis. Three (5.4%) cases of HBV reactivation occurred: 2 in pre-transplant anti-HBc-positive recipients and 1 with prior unknown anti-HBc status. All were HBeAg+ with HBV deoxyribonucleic acid (DNA) >10E8 IU/mL and only mild fibrosis. Baseline recipient anti-HBc positive status was the only factor associated with HBV reactivation. No reactivation cases occurred in lung or kidney recipients of anti-HBc positive grafts. Survival was lower in lung transplants, especially in human immunodeficiency virus-infected patients and those with prior immunosuppression.Anti-HBc positive status is a risk factor for HBV reactivation in solid organ recipients. Anti-HBc testing is highly recommended in solid-organ transplant recipients in order to identify those anti-HBc positive and therefore candidates for periodical hepatitis B surface antigen (HBsAg) and HBV DNA screening after transplant.

Abstract
OBJECTIVE HIV positive individuals infected with viral hepatitis B (HBV) or C (HCV) are at an increased risk of progression to kidney and liver failures. Therefore, prior to initiation of antiretroviral therapy, early diagnosis and initiation of appropriate treatment protocols are imperative for co-infected individuals. This study evaluated the prevalence of HBV and HCV, and extent of liver and renal dysfunction among 90 newly diagnosed HIV patients attending the Cape Coast Teaching Hospital HIV clinic. RESULTS Levels of alanine aminotransferase, aspartate-platelet ratio index and estimated glomerular filtration rate were used respectively to diagnose hepatotoxicity, liver fibrosis and chronic kidney disease (CKD). Association analyses were evaluated by Pearson's Chi-square test or Fisher's exact test and considered significant at p < 0.05. Using rapid diagnostic tests, 75.6% (n = 68) had HIV1 mono-infection, 24.4% (n = 22) had HIV1/HBV co-infection while 0.0% (n = 0) had HIV1/HCV co-infection. The prevalence of hepatotoxicity, liver fibrosis, and CKD were 7.8% (n = 7), 2.2% (n = 2), and 15.5% (n = 14) respectively. Similar proportions of HIV1/HBV and HIV1 were diagnosed with liver fibrosis (p = 0.431). In relation to hepatotoxicity Grade, a high proportion of HIV1/HBV were diagnosed with Grade 2 (p = 0.042). Also, severely reduced kidney function (CKD stage 4) was observed in only HIV1/HBV (n = 2, 9.1%, p = 0.053).

Abstract
A 34-year-old woman experiencing shortness of breath was referred to our hospital. The patient was diagnosed with sporadic lymphangioleiomyomatosis based on the observation of bilateral diffuse multiple thin-walled cysts on computed tomography of the chest, chylous effusion, elevated serum vascular endothelial growth factor-D levels and transbronchial biopsy findings. This patient was a hepatitis B virus (HBV) carrier. Treatment with 1 mg daily of sirolimus was started after HBV DNA was brought below the cut-off level using entecavir. Sirolimus was effective, as the chylous effusion resolved completely and the dyspnea improved. The sirolimus dosage was increased to 2 mg daily without causing HBV reactivation.

Abstract
Restoring antiviral immunity is a promising immunotherapeutic approach to the treatment of chronic hepatitis B virus (HBV) infection. Dendritic cells play a crucial role in triggering antiviral immunity. In this study, we identified immunodominant epitopes prevalent in CD8+ T cell responses. We characterized the hierarchy of HBV epitopes targeted by CD8+ T cells following autologous monocyte-derived dendritic cell (moDC) expansion in HBV-infected subjects with distinct disease stages: treatment-naïve (TN group, n = 168), treatment with complete virological response (TR group, n = 72), and resolved HBV infection (RS group, n = 28). T cell responses against 32 HBV epitopes were measured upon moDC expansion. Several subdominant epitopes that triggered HBV-specific CD8+ T cell responses were identified. These epitopes’ responses varied in individuals with different disease stages. Moreover, the most immunodominant and immunoprevalent epitope included the envelope residues 256-270 (Env256-270), corresponding to amino acid residues 93-107 in the small HBV surface protein (SHBs) across three patient groups. The frequency of Env256-270-specific interferon-γ-producing T cells was the highest in the RS group and the lowest in the TN group. In addition, individuals with HLA-A*02:03/02:06/02:07 were capable of responding to Env256-270. Env256-270-specific CD8+ T cells tolerated amino acid variations within the epitope detected in HBV genotypes B and C. This suggests that Env256-270 in SHBs is crucial in HBV-specific T cell immunity following autologous moDC expansion. It might be a potential target epitope for dendritic-cell-based immunotherapy for CHB patients with complete viral suppression by long-term NAs treatment.

Abstract
BACKGROUND Hepatitis B is one of the most common infectious diseases in China, and it is necessary to study biochemical indicators of HBV infected patients. METHODS Biochemical and basic features of 1765 HBV infected patients and 840 general controls were collected and analyzed from Southwest China. RESULTS A total of 23.5% of the patients were children or young persons (less than 40 years old). The co-infected rate was only 0.3% for those who were co-infected with Hepatitis C virus (HCV) or Treponema pallidum (TPa). Most of patients (1081 individuals) were under convalescent condition, and 4.2% and 34.6% HBV patients were at acute and chronic phase, respectively. The indicators of liver function were significantly different between HBV patients and normal controls. In order to further study the variation of biochemical features in HBV patients in different phase, they were divided into three groups (sample #1: patients in acute infected phase; sample #2: patients in chronic infected phase; and sample #3: patients in convalescent condition). Excluding total protein and globin, all other indicators of liver function were statically different among the three groups. Total protein and albumin gradually decreased from convalescent patients, chronic HBV-infected patients, to acute HBV-infected patients. CONCLUSIONS Biochemical features could be used to evaluate the progress and therapeutic effects of HBV-infection. Our analysis firstly reported basic and biochemical information of HBV patients in Southwest China.

Abstract
Aims: To investigate the relationship between extracellular water to total body water ratio (ECW/TBW) in bioimpedance analysis (BIA) and clinical parameters in hepatitis viruses related to liver diseases. Methods: ECW/TBW was compared in patients with hepatitis B virus (HBV, n = 85) and hepatitis C virus (HCV, n = 440) related liver diseases. We also examined factors linked to mild to severe overhydrated state (ECW/TBW ≥0.4). Results: The median ECW/TBW in the HCV group was 0.388 (range, 0.365–0.433), while that in the HBV group was 0.381 (range, 0.363–0.425) (p < 0.0001). In all cases (n = 525), for predicting F3 or more, ECW/TBW yielded the area under the receiver operating characteristics (AUROC, 0.74912) and for predicting F4, ECW/TBW yielded the AUROC (0.75517). Multivariate analysis showed that age, prothrombin time, serum albumin, and alanine aminotransferase were significant factors linked to ECW/TBW ≥0.4. In patients with FIB-4 index <2, ECW/TBW in the HCV group was significantly higher than that in the HBV group (p = 0.0188), while in patients with 2 ≤ FIB-4 index <4 and FIB-4 index ≥4, the difference in the two groups did not reach significance. Conclusion: ECW/TBW can be different according to hepatitis viruses. Overhydrated status can easily occur in the HCV group even in the non-LC status compared with the HBV group.

Abstract
BACKGROUND The aim of this study was to investigate the reactivation of the hepatitis B virus (HBV) following transarterial chemoembolization (TACE) in primary hepatocellular carcinoma (HCC) patients with HBV-DNA negative and to evaluate the effects of TACE combined with antiviral therapy. METHODS This prospective study involved 98 patients with HBV-related and HBV-DNA negative HCC (HBV DNA < 10 copies/mL) underwent TACE procedures with serial HBV DNA tests. Patients were divided into the antiviral treatment group and the no-antiviral group. The antiviral group received entecavir antiviral therapy, and the other group received no antiviral therapy. Two groups of patients were compared in rate of HBV reactivation and liver function before and after only 1 session of TACE in average 1-month follow-up after operation. P < .05 indicated differences with a statistical significance. RESULTS HBV reactivation occurred in 11 patients in the nonantiviral group (11/47, 23.4%) but only 3 patients in the antiviral group (3/51, 5.9%, P < .05). On multivariate analysis, HBeAg-positive status, number of tumors more than 3, and absence of antiviral therapy were the independent risk predictor of HBV reactivation. Liver function indicators did not differ significantly between the antiviral group and the nonantiviral group in 5 days after TACE. However, the level of alanine aminotransferase and bilirubin were raised and albumin was reduced at the HBV reactivation group compared with no HBV reactivation group (P < .05). At 1 month after TACE, liver function indicators did not differ significantly between the HBV reactivation group and without HBV reactivation group. CONCLUSION HCC patients with HBV DNA negative still remain associated with risk of HBV reactivation after TACE. HBeAg-positive, number of tumors more than 3, and absence of antiviral therapy in HCC patients after TACE have a higher risk of HBV reactivation. Antiviral therapy can reduce the risk of reactivation, helping improve liver function after TACE.

Abstract
Simultaneous liver, pancreas-duodenum, and kidney transplantation has been rarely reported in the literature. Here we present a new and more efficient en bloc technique that combines classic orthotopic liver and pancreas-duodenum transplantation and heterotopic kidney transplantation for a male patient aged 44 years who had hepatitis B related cirrhosis, renal failure, and insulin dependent diabetes mellitus (IDDM). A quadruple immunosuppressive regimen including induction with basiliximab and maintenance therapy with tacrolimus, mycophenolate mofetil, and steroids was used in the early stage post-transplant. Postoperative recovery was uneventful and the patient was discharged on the 15th postoperative day with normal liver and kidney function. The insulin treatment was completely withdrawn 3 wk after operation, and the blood glucose level remained normal. The case findings support that abdominal organ cluster and kidney transplantation is an effective method for the treatment of end-stage liver disease combined with uremia and IDDM.

Abstract
Hepatitis B virus (HBV) is a major etiologic agent of acute and chronic hepatitis, and end-stage liver disease. Establishment of HBV infection, progression to persistency and pathogenesis are determined by viral and cellular factors, some of which remain still undefined. Key steps of HBV life cycle e.g., transformation of genomic viral DNA into transcriptionally active episomal DNA (cccDNA) or transcription of viral mRNAs from cccDNA, take place in the nucleus of infected cells and strongly depend on enzymatic activities provided by cellular proteins. In this regard, DNA damage response (DDR) pathways and some DDR proteins are being recognized as important factors regulating the infection. On one hand, HBV highjacks specific DDR proteins to successfully complete some of the steps of its life cycle. On the other hand, HBV subverts DDR pathways to presumably create a cellular environment that favours its replication. Direct consequences of these interactions are: HBV DNA integration into host chromosomal DNA, and accumulation of mutations in host chromosomal DNA that could eventually trigger carcinogenic processes, which would explain in part the incidence of hepatocellular carcinoma in chronically infected patients. Unravelling the interactions that HBV establishes with DDR pathways might help identify new molecular targets for therapeutic intervention.

Abstract
The aim of study was to investigate the clinical features of treatment-naive patients in 2 regions with high- and intermediate-hepatitis B endemicity level in Southeast China and provide the baseline data for monitoring health or planning therapy.This study included 8207 cases of treatment-naive patients with hepatitis B virus (HBV) infection from Yuhuan (YH, high-hepatitis B endemicity region) and Shaoxing (SX, intermediate-hepatitis B endemicity region) during 2014-2015. Clinical data were collected from the patients. Blood samples were kept for detecting hepatitis B surface antigen, hepatitis B envelope antigen (HBeAg), hepatitis B envelope antibody, hepatitis B surface antibody, hepatitis B core antibody, liver function, HBV deoxyribonucleic acid, and alpha-fetoprotein. All persons underwent B ultrasound to exclude liver cirrhosis or cancer.Of all 8207 HBsAg-positive patients, 52.9% patients were in the low-replication (LR) stage and 30.3% in the HBeAg-negative chronic hepatitis B (ENH) stage; 8.8% cases were in the ENH stage with elevated alanine aminotransferase (ALT). More male than female patients were in immune clearance (IC) or ENH stages with elevated ALT (10.4% vs 4.8%, 12.1% vs 5.3%, respectively, P < .05). The percentage of patients in IC and immune tolerant (IT) stages declined with increasing age, whereas the percentages of ENH with elevated ALT stage were highest in 40 to 60 years.The percentage of patients in IT and IC stages was higher in YH than in SX (9.4% vs 3.8%, 9.9% vs 4.2%, respectively, P < .05). More patients had HBVDNA≥10 IU/mL in YH than in SX (24.6% vs 16.0%, P < .05), and more male than female patients had HBVDNA≥10 IU/mL(24.5% vs 17.9%, P < .05).Clinical features varied in treatment-naive patients with HBV infection between different genders and regions. More attention should be paid to the surveillance and therapy of patients in YH especially male patients for the prevention and prognosis of hepatitis B.

Abstract
RATIONALE Bleeding esophageal and gastric varices constitute a serious complication in liver cirrhosis. Previous studies have shown that endoscopic ultrasonography (EUS) can be used to predict early esophageal variceal bleeding in liver cirrhosis. PATIENT CONCERNS We report a case of a 46-year-old man with hepatitis B liver cirrhosis (CTP score, 5; Child-Pugh class, A) who was admitted to our hospital due to a decreased appetite lasting 1 week. DIAGNOSIS He was initially diagnosed with decompensated hepatitis B cirrhosis; an abdominal computed tomography (CT) scan indicated a diagnosis of liver cirrhosis and portal hypertension (PHT). INTERVENTIONS Common endoscopic examination showed no evidence of gastroesophageal varices; EUS revealed distinct varices of the esophageal and gastric veins. Six months after discharge, the patient was rehospitalized because of upper gastrointestinal bleeding. Endoscopic ligation was implemented as well as esophageal varices loop ligature (EVL). OUTCOMES Six months later, EUS showed obvious collateral and perforator veins. LESSONS We should strongly recommend that patients with liver cirrhosis undergo EUS in addition to a routine endoscopic examination. EUS can play an important role in evaluating the risk for bleeding in PHT and can be used to assess the efficacy of EVL.

Abstract
Objective To construct an animal model in which hepatitis B virus X protein (HBx) directly affect hepatic progenitor cells (HPCs), and investigate the potential mechanisms underlying epithelial-mesenchymal transition (EMT) of HPCs. Methods Kunming mice were given 2 mL/L carbon tetrachloride (CCL4) in oil solution by gavage twice a week. Four weeks later, HPCs transfected with recombinant lentiviral vectors stably expressing HBx gene as well as empty vectors were separately injected into the mice via the portal vein, and at the same time, the mice underwent a partial hepatectomy. The gavage twice a week continued after the operation. And on days 3, 5, 7, 14, 21 28 postoperation, the mice were sacrificed and the livers were removed. Fluorescence quantitative PCR was used to detect the mRNA expression level of HBx; immunohistochemistry was performed to observe the exogenous cell survival in vivo. The expression levels of E-cadherin, N-cadherin, vimentin and CK18 were assessed by fluorescence quantitative PCR and Western blotting. Results Immunohistochemistry showed that the exogenous cells obviously survived in vivo in the postoperative liver tissues. Moreover, the expression of HBx was enhanced and expanded over time. Fluorescence quantitative PCR and Western blotting showed that overexpressed HBx downregulated the expressions of E-cadherin and CK18, while upregulated the expressions of N-cadherin and vimentin. Conclusion HBx plays an important role in the regulation of EMT of HPCs in vivo.

Abstract
Various viral kinetics among patients with acute hepatitis B (AHB) have been observed in clinical practice. This study investigated the virological, biochemical, and serological characteristics of AHB in adults.A total of 192 adult patients with AHB were recruited between December 2010 and January 2014. The quantification of biochemical and serologic markers for hepatitis B virus (HBV) infection was monitored from the onset.Of the 192 patients, 113 patients were followed up. One patient died due to acute liver failure, 2 developed chronic HBV infection. Clinical recovery was observed in 110 patients; 92.7% (102/110) achieved clinical recovery within 24 weeks, and 7.3% (8/110) between 24 and 44 weeks. There were 3 different viral kinetics patterns among the patients with AHB: the clearance of HBV DNA preceded hepatitis B e antigen (HBeAg) and hepatitis B surface antigen (HBsAg), the clearance of HBeAg preceded HBV DNA and HBsAg, the clearance of HBsAg preceded HBV DNA and HBeAg.In the absence of HBV DNA clearance within 13 weeks, the risk of development of chronic HBV infection increased. The serologic HBV markers clearance occurred between 24 and 44 weeks (6-11 months) from the onset in 8 of the AHB patients, which was longer than 6 months. Thus, AHB may be redefined as HBV DNA undetectable, HBsAg and HBeAg seroconversion within 44 weeks.

Abstract
There is emerging evidence for the positive effects or benefits of coffee in patients with liver disease. We conducted a retrospective cross-sectional study on patients with non-alcoholic fatty liver disease (NAFLD), hepatitis C virus (HCV), and hepatitis B virus (HBV) infection to determine the effects of coffee intake on a non-invasive marker of liver fibrosis: liver stiffness assessed by transient elastography (TE). We assessed coffee and tea intake and measured TE in 1018 patients with NAFLD, HCV, and HBV (155 with NAFLD, 378 with HCV and 485 with HBV). Univariate and multivariate regression models were performed taking into account potential confounders. Liver stiffness was higher in males compared to females (p < 0.05). Patients with HBV had lower liver stiffness than those with HCV and NAFLD. After adjustment for age, gender, smoking, alcohol consumption, M or XL probe, and disease state (NAFLD, HCV, and HBV status), those who drank 2 or more cups of coffee per day had a lower liver stiffness (p = 0.044). Tea consumption had no effect (p = 0.9). Coffee consumption decreases liver stiffness, which may indicate less fibrosis and inflammation, independent of disease state. This study adds further evidence to the notion of coffee maybe beneficial in patients with liver disease.

Abstract
A 68-year-old man with occult hepatitis B virus (HBV) infection was diagnosed with malignant lymphoma and achieved complete remission after treatment with a chemotherapy regimen including rituximab for 5 months. Entecavir (ETV) was also used during and after chemotherapy and was ended at 14 months after chemotherapy. However, reactivation of HBV was observed in blood tests, which showed not only elevation of HBV-DNA but also HBsAg and HBeAg, at 27 months after the end of chemotherapy. After restarting ETV, the HBV-DNA levels immediately subsided. In addition, anti-HBs became and remained positive at 31 months after chemotherapy. ETV was re-discontinued at 36 months after chemotherapy.

Abstract
Aim To evaluate the diagnostic accuracy and clinical utility of the fibrosis index based on the four factors (FIB-4), aspartate aminotransferase -to-platelet ratio index (APRI), and aspartate aminotransferase–alanine aminotransferase ratio index (AAR) for predicting liver fibrosis in patients with HBV infection. Methods From January 2006 to December 2010,a total of 1543 consecutive chronic hepatitis B(CHB) patients who underwent liver biopsies were enrolled. FIB-4,APRI, and AAR were calculated.The areas under the receiver-operating characteristic curves (AUROCs) were calculated to assess the diagnostic accuracy of these models.The AUROCs of these models were compared by DeLong’s test.For further comparisons in different studies,the AUROCs were adjusted to conduct Adjusted AUROCs(ADjAUROCs) according to the prevalence of fibrosis stages using the difference between advanced and nonadvanced fibrosis (DANA). Results For prediction of significant fibrosis,severe fibrosis,and cirrhosis,the AUROCs of FIB-4 were 0.646(ADjAUROC 0.717),0.670(ADjAUROC 0.741), and 0.715(ADjAUROC 0.786) respectively;whereas it were 0.656(ADjAUROC 0.727),0.653(ADjAUROC 0.724) and 0.639(ADjAUROC 0.710) for APRI, 0.498(ADjAUROC 0.569),0.548(ADjAUROC 0.619) and 0.573(ADjAUROC 0.644) for AAR. The further comparisons demonstrated that there were no significant differences of AUROCs between FIB-4 and APRI in predicting significant and severe fibrosis(P > 0.05),while FIB-4 was superior to APRI in predicting cirrhosis(P < 0.001). Further subgroup analysis demonstrated that the diagnostic accuracy of FIB-4 and APRI in patients with normal alanine aminotransferase(ALT) were higher than that in patients with elevated ALT. Conclusions The results demonstrated that FIB-4 and APRI are useful for diagnosis of fibrosis. FIB-4 and APRI have similar diagnostic accuracy in predicting significant and severe fibrosis,while FIB-4 is superior to APRI in predicting cirrhosis. The clinical utility of FIB-4 and APRI for fibrosis need further external validation in a large population before it was used for prediction of fibrosis in patients with HBV infection.

Abstract
OBJECTIVE To assess the clinical significance of hepatitis B virus (HBV) infection in patients with cerebral venous sinus thrombosis (CVST). METHODS Twenty-two patients with CVST confirmed by magnetic resonance venography (MRV) or digital subtraction angiography (DSA) and 743 controls with ischemic stroke confirmed by magnetic resonance imaging (MRI) were analyzed retrospectively. RESULTS Among all researches, HBV surface antigen (HBsAg)-positive rate was high. Six of the 22 (27.3%) confirmed cases had HBsAg. However, HBsAg-positive rate in patients with ischemic stroke was only 45 of the 743 cases (6.1%), closed to the average prevalence in China (∼ 8.6%), but much lower than the positive rate in CVST patients (27.3 vs 6.1%, P = 0.002). Odd ratio (OR) value between HBsAg-positive CVST patients (27.3%) and HBsAg-positive ischemic stroke patients (6.1%) was 5.78. The OR value between HBsAg-positive CVST patients (27.3%) and average prevalence of HBV infection in China (8.6%) was nearly 3.99. It meant that HBV infection might be a risk factor for CVST. However, there existed no statistically significant difference in HBV surface antibody (HBsAb), HBV e antigen (HBeAg), HBV e antibody (HBeAb), and HBV central antibody (HBcAb)-positive rate. The HBV surface antigen (HBsAg)-positive CVST patients did not show worse liver function. Most of them were inactive HBV carriers. CONCLUSION Hepatitis B virus infection may be a risk factor for CVST.

Abstract
Reactivation of hepatitis B virus (HBV) is a potentially fatal complication after anti-B-cell therapy. It can develop not only in patients seropositive for hepatitis B surface antigen (HBsAg), but also in those with resolved HBV infection who are seronegative for HBsAg but seropositive for antibodies against hepatitis B core antigen (anti-HBc) and/or antibodies against HBsAg (anti-HBs). The risk of HBV reactivation depends on the balance between replication of the virus and the immune response of the host. Anti-CD20 monoclonal antibody-rituximab in combination with steroid-containing chemotherapy (R-CHOP: rituximab + cyclophosphamide + hydroxydaunorubicin + vincristine + prednisone/prednisolone)-is an important risk factor for HBV reactivation in HBsAg-negative patients. More obviously, HBsAg-positive patients are considered to be at very high risk for HBV reactivation and, in the rituximab era, 59%-80% of these patients develop HBV reactivation after R-CHOP-like chemotherapy. Patients with resolved HBV infection should also be considered at high risk of HBV reactivation, the incidence of which is reported to be 9%-24% in such lymphoma patients. All patients should be screened to identify risk groups for HBV reactivation before initiating anti-B-cell therapy by measuring serum HBV markers including HBsAg, anti-HBc and anti-HBs. To prevent the development of hepatitis due to HBV reactivation after anti-B-cell therapy, antiviral prophylaxis is recommended for HBsAg-positive patients and/or patients in whom HBV DNA is detectable at baseline, whereas regular monitoring of HBV DNA-guided preemptive antiviral therapy is a reasonable and useful approach for patients with resolved HBV infection.

Abstract
Aberrant brain functional connectivity has been considered as the important mechanism underlying minimal hepatic encephalopathy (MHE); however, little is known about the change in interhemispheric connection in MHE patients. Twenty patients with HBV-related cirrhosis and MHE and 15 healthy controls were included in this study and underwent the resting-state fMRI scanning and diffusion tensor imaging. The functional connectivity between symmetric interhemispheric voxels was computed by a technique called voxel-mirrored homotopic connectivity (VMHC), in which the time series for each voxel in one hemisphere was correlated with that of its homotopic voxel. Diffusion tensor imaging was conducted to measure the mean diffusivity (MD) and fractional anisotropy (FA) values in corpus callosum (CC). Compared with controls, MHE patients showed decreased regional VMHC in medial frontal gyrus, superior frontal gryus, anterior cingulate gyrus, inferior parietal lobule, postcentral gyrus, lingual gyrus, and middle occipital gyrus. MHE patients had significant decreased FA value in CC genu and CC splenium and increased MD value in CC genu. Pearson correlation analyses showed that the VMHC in anterior cingulate gyrus/medial frontal gyrus was correlated with FA/MD values of CC genu. These findings may suggest aberrant interhemispheric coordination in MHE and may provide new insight into the disease-related mechanisms.

Abstract
In this study, we investigated whether hepatitis B virus (HBV) causes the alteration of lipid metabolism and composition during acute infection and liver regeneration in a mouse model. The liver controls lipid biogenesis and bile acid homeostasis. Infection of HBV causes various liver diseases and impairs liver regeneration. As there are very few reports available in the literature on lipid alterations by HBV infection or HBV-mediated liver injury, we have analyzed phospholipids that have important roles in liver regeneration by using matrix-assisted laser desorption/ionization (MALDI)-imaging mass spectrometry (IMS) in the livers of HBV model mice. As a result, we identified different phosphatidylcholines (PCs) showing significant changes in their composition as well as cationized ion adduct formation in HBV-infected mouse livers which are associated with virus-mediated regeneration defects. To find the factor of altered PCs, the expression kinetics of enzymes was also examined that regulate PC biosynthesis during liver regeneration. It is noteworthy that the expression of choline-phosphate cytidylyltransferase A (PCYT1A) was significantly delayed in wild type HBV-expressing livers. Moreover, the amount of hepatic total PC was also significantly decreased in wt HBV-expressing mice. These results suggest that infection of HBV alters the composition of PCs which may involve in HBV-mediated regeneration defects and liver disease.

Abstract
AIM/BACKGROUND Few data are available about the prevalence of hepatitis B and C infections in early breast cancer patients and its impact on systemic treatments. The objectives of this study were to determine the incidence of positive serology for hepatitis B and C in women with early breast cancer and to assess the clinical course and its impact on liver function during adjuvant treatments. PATIENTS AND METHODS we retrospectively reviewed hepatitis B and C serology [HBs antigen (HBsAg), HBc antibodies (HBcAb), HBs antibodies (HBsAb) and HC (HCV) antibodies] in 746 consecutive patients with early breast cancer treated at our Institution between 2009 and 2011. RESULTS Among 375 evaluable patients, we identified 312 controls (83.2%) and 63 patients (16.8%) with positive serology (cases): 15 patients (4%) with HCV, 8 (2.1%) with resolved HBV without anti-HBs (HBsAg-negative, HBsAgAb-negative, HBcAgAb-positive), 36 (9.6%) with resolved HBV with anti-HBs (HBsAg-negative, HBsAgAb-positive, HBcAgAb-positive) and 4 (1%) with chronic HBV (HBsAg-positive, HBsAgAb-negative, HBcAgAb-positive). During systemic treatments, hepatitis (defined as at least a three-fold increase in serum alanine aminotransferase level) occurred in nine (20.4%) out of 44 evaluable cases and in 14 (5.9%) out of 234 evaluable controls. CONCLUSION Approximately 20% of patients with early breast cancer with positive serology for viral hepatitis may develop hepatitis during systemic treatment. Pre-treatment serum detection of viral hepatitis B and C antigens and antibodies may be useful in the adjuvant therapy decision-making process and for adequate monitoring of liver function during antineoplastic therapy.

Abstract
OBJECTIVE To investigate the variability in liver stiffness (LS), measured by transient elastography, and determine the possible influencing factors in hepatitis B virus infection. METHODS This cross-sectional study was conducted at the Department of Infectious Diseases, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei Province, China from March to June 2010. Three successful measurements at different sites in 123 patients were obtained, and the LS discrepancy was calculated. The influence of clinical data on the discrepancy was also assessed. RESULTS The LS discrepancy was 1.3 (0.2-16.5) kPa and independently increased with a fibrosis stage: 0.9 (0.2-4.4) kPa in F0/F1, 1.5 (0.4-3.7) kPa in F2, 3.0 (0.3-9.4) kPa in F3, and 7.4 (3.1-16.5) kPa in F4. A discrepancy >/=2 kPa was observed in 45 (36.6%) patients: 8 (11.9%) with F0/F1, 7 (31.8%) with F2, 15 (73.7%) with F3, and 15 (100%) with F4. The incidence of discrepancy >/=2 kPa was only associated with fibrosis stage in multiple regression analysis. Discordance in fibrosis stages was observed in 33 (26.8%) patients, and was most frequent in stage F2 (F0/F1, 10.45%; F2, 68.2%; F3, 36.8%; and F4, 26.7%). CONCLUSION The LS discrepancy is common and associated with fibrosis stage independently. While determining the fibrosis stage and disease progression, LS discrepancy should be considered.

Abstract
UNLABELLED It is well established that interleukin (IL)-22 has hepatoprotective and antifibrotic functions in acute liver injury models; however, its function in patients with liver fibrosis and liver cirrhosis (LC) remains obscure. In the current study, we demonstrated that expression of numerous IL-22 pathway-associated genes was significantly up-regulated in hepatitis B virus (HBV)-infected liver tissues, compared to normal controls, through microarray analysis. In agreement with these findings, liver-infiltrating IL-22(+) cells were largely increased in HBV-infected patients with LC, compared to those without LC or healthy subjects, and were positively associated with liver fibrosis staging scores. Immunohistochemistry and flow cytometric analyses revealed that IL-22 was produced by multiple intrahepatic immune cells and, preferentially, by T-helper (Th) 17 cells in LC patients. In an HBV transgenic (Tg) mouse model of T-cell-mediated chronic liver inflammation and fibrosis, blockade of IL-22 attenuated hepatic expression of chemokine (C-X-C motif) ligand 10 and chemokine (C-C motif) ligand 20 (CCL20) and subsequently reduced Th17 recruitment and liver inflammation and fibrosis progression. In vitro treatment with IL-22 stimulated hepatic stellate cells (HSCs) to secrete several chemokines and subsequently promoted Th17 cell chemotaxis. Blocking C-X-C chemokine receptor type 3 or CCL20 reduced Th17 cell chemotaxis by IL-22-treated HSCs. CONCLUSIONS IL-22 plays a pathological role in exacerbating chronic liver inflammation and fibrosis by recruiting hepatic Th17 cells in HBV-infected patients and HBV Tg mice.

Abstract
OBJECTIVES Rheumatoid factor (RF) can be seen in hepatitis B virus (HBV) infection. We investigated RF positive rates according to various HBV infectious statuses and vaccination, and the relationship between RF titers and serum HBV DNA levels. METHODS We examined 13,670 individuals who visited the Severance Hospital in Seoul, Korea, for a routine health check-up, and obtained serum samples from all individuals. RESULTS RF was positive in 3.5% of all subjects, and HBsAg was positive in 4.3%. HBsAg was positive in 21.7% of all RF positive subjects. RF was positive in 17.5% of the HBsAg positive group, while it was positive in 2.9% of the HBsAg negative group (p<0.001). The RF positive rate was increased in positive HBsAg, female sex, and older age. The RF positive rate was lower in those who had anti-HBs after HBV vaccination than in HBsAg positive subjects (2.7% vs. 17.5%, p<0.001). Among the RF positive patients, the RF titer in HBsAg positive patients were higher than that in HBsAg negative patients (159.7±217.1IU/mL vs. 83.0±179.2 IU/mL, p=0.001). The load of HBV DNA may be closely correlated with RF titer in patients with chronic hepatitis B (r=0.508, p=0.005). CONCLUSIONS Persistent HBV infection is an important cause for the positive RF in HBV endemic areas. Hepatitis B viral load is associated with RF titer. HBV vaccination may reduce the risk of RF formation.

Abstract
Chronic hepatitis B is a growing worldwide public health issue. Its prevalence and the mode of transmission of the virus varies greatly between parts of the world. Prevalence is rising in the UK due to an increase in migration from areas with a high prevalence of chronic hepatitis B. This article, the first of a two-part series, discusses the prevalence and pathophysiology of chronic hepatitis B, as well as recommendations for screening high-risk groups and immunisation against the disease. Part two discusses the management of the virus.

Abstract
UNLABELLED The liver is considered as a unique lymphoid organ favoring the induction of immune tolerance, rather than immunity. Biologists and clinicians alike have a long-standing interest in how the liver induces systemic immune tolerance, but the mechanism has not yet been well elucidated. Here, we employed hepatitis B virus (HBV)-carrier mice generated by hydrodynamically injecting phosphor-adeno-associated virus/HBV1.2 plasmid as a model for adult chronic HBV infection, which we found were unable to respond to hepatitis B surface antigen vaccination. Humoral tolerance induced in HBV-carrier mice could be transferred into Rag1(-/-) mice, because anti-HBV immunity in immunologically reconstituted Rag1(-/-) mice was inhibited by adoptive transfer of splenocytes from HBV-carrier mice. Humoral tolerance needed at least 7 days for induction and persisted to 3 months after a single HBV plasmid injection. Kupffer cell (KC) depletion or interleukin (IL-10) deficiency broke this humoral tolerance, and exogenous injection of IL-10 could effectively induce this tolerance. CONCLUSION KCs in HBV-carrier mice expressed more IL-10 and mediated the systemic tolerance induction in an IL-10-dependent manner. This previously undescribed humoral tolerance regarding HBV infection will help to explore new approaches to reverse liver-sustained systemic immune tolerance in liver disease.

Abstract
OBJECTIVE To investigate the apoptosis regulation on hepatoma cells by HBx between genotype B and C. METHODS Genotype B and C HBx gene fragments were amplified and inserted into green fluorescent protein (GFP) eukaryotic expression vector pEGFP-C1 to construct recombinant pGFP-XB and pGFP-XC. The pEGFP-C1, pGFP-XB and pGFP-XC were introduced into Bel-7402 cells by Fugene HD to obtain Bel-7402 cells expressing GFP. The transcription and expression of HBx gene were demonstrated by RT-PCR and Western Blot analysis. Bel-7402, Bel-7402/GFP, Bel-7402/GFP-XB, Bel-7402/GFP-XC cells were treated with adriamycin (2.5 microg/ml), and the apoptosis of the cells was determined by trypan blue exclusion, and flow cytometry analysis. RESULTS RT-PCR and Western Blot analysis showed that HBx genes of genotypes B and C were transcribed and expressed in Bel-7402/GFP-XB, Bel-7402/GFP-XC cells. Trypan blue exclusion showed adriamycin induced time-dependent cell death in Bel-7402, Bel-7402/GFP cells while no significant cell death was observed in Bel-7402/GFP-XB, Bel-7402/GFP-XC cells. Flow cytometry analysis indicated that no significant differences of apoptosis rates of Bel-7402/GFP-XB (3.87%) and of Bel7402/GFP-XC (4.01%) were observed (P > 0.05), moreover, no significant differences of Bel-7402/ GFP-XB (3.87%), Be17402/GFP-XC (4.01%) and of the untreated cells. Apoptosis rates in Bel-7402/GFP-XB (3.87%), Bel-7402/GFP-XC (4.01%) cells were significantly lower than those in Bel-7402 (27.05%) and Bel-7402/GFP (29.14%) cells at 48 hours after the adriamycin treatment (P < 0.01). CONCLUSIONS Bel-7402 cell lines expressing GFP, GFP-XB and GFP-XC fusion proteins were successfully established. HBV X protein blocks adriamycin-induced apoptosis of Bel-7402 cells. There is no difference between HBx of genotype B and C in inhibiting apoptosis induced by adriamycin.

Abstract
Neurocognitive dysfunction of varying degrees is common in patients with hepatitis B virus-related cirrhosis (HBV-RC) without overt hepatic encephalopathy (OHE). However, the neurobiological mechanisms underlying these dysfunctions are not well understood. We sought to identify changes in the neural activity of patients with HBV-RC without OHE in the resting state by using the amplitude of low-frequency fluctuation (ALFF) method and to determine whether these changes were related to impaired cognition. Resting-state functional MRI data from 30 patients with HBV-RC and 30 healthy controls matched for age, sex, and years of education were compared to determine any differences in the ALFF between the two groups. Cognition was measured with the psychometric hepatic encephalopathy score (PHES), and the relationship between these scores and ALFF variation was assessed. Compared with controls, patients showed widespread lower standardized ALFF (mALFF) values in visual association areas (bilateral lingual gyrus, middle occipital gyrus, and left inferior temporal gyrus), motor-related areas (bilateral precentral gyrus, paracentral lobule, and right postcentral gyrus), and the default mode network (bilateral cuneus/precuneus and inferior parietal lobule). Higher mALFF values were found in the bilateral orbital gyrus/rectal gyrus. In patients, mALFF values were significantly positive correlated with the PHES in the right middle occipital gyrus and bilateral precentral gyrus. Our findings of resting-state abnormalities in patients with HBV-RC without OHE suggest that neurocognitive dysfunction in patients with HBV-RC without OHE may be caused by abnormal neural activity in multiple brain regions.

Abstract
Hepatocellular carcinoma (HCC) is a deadly and emerging disease leading to death in Asian countries. High hepatitis B virus (HBV) load and chronic hepatitis B (CHB) infection increase the risk of developing HCC. HBV is a DNA virus that can integrate DNA into host genome thereby increase the yield of transactivator protein HBxAg that may deregulate many pathways involving in metabolism of cells. Several monogenic and polygenic risk factors are also involved in HCC development. This review summarizes the mechanism involved in HCC development and discusses some promising therapies to make HCC curative.

Abstract
BACKGROUND/AIMS Single-nucleotide polymorphisms (SNPs) near the interleukin 28B gene (IL28B; interferon [IFN]-λ-3) are associated with outcomes of chronic hepatitis C virus (HCV) and hepatitis B virus (HBV) infection treated with peginterferon (PEG-IFN) alpha-based antiviral therapy. In this study, we investigated the influence of IL28B polymorphisms on spontaneous clearance of HBV infection in a large Korean cohort. METHODS Between January 2007 and June 2010, a total of 208 patients with chronic HBV infection and newly diagnosed HBV-related hepatocellular carcinoma were recruited as the CC group [HBsAg(+) for >6 months, anti-HBc(+), and anti-HBs(-)]. In addition, 351 organ donors were stratified into the UE group [n = 106; HBsAg(-), anti-HBc(-), and anti-HBs(-)] or the SC group [n = 245; HBsAg(-), anti-HBc(+), and anti-HBs(+)]. The SNaPshot ddNTP Primer Extension Kit (Applied Biosystems, Foster City, CA) was used for SNP detection. Direct full sequencing of the IL28B coding region was attempted. RESULTS Regardless of group, rs12979860 CC was most frequently identified (85.0% in UE, 85.9% in SC, and 93.5% in CC, respectively), whereas rs12979860 TT was not identified in any group. Similarly, rs12980275 AA and rs8099917 TT were most frequently identified (≥85%) regardless of group, whereas rs12980275 GG was identified in only one subject in the SC group. In addition, rs8099917 GG was not identified. The prevalences of CC in rs12979860, AA in rs12980275, and TT in rs8099917 were significantly higher in the CC group when compared with the UE and SC group (all P<0.05). Among 19 novel SNPs in the IL28B coding region, the proportions of 6 SNPs were significantly different among the UE, SC, and CC groups (all P<0.05). CONCLUSIONS The SNP upstream of IL28B that has the strongest genetic association with HCV recovery has an inverse influence on HBV recovery. Additional studies are needed to understand the mechanisms of this SNP in HBV infection.

Abstract
Hepatitis B virus (HBV) is hepatotropic and lymphotropic. HBV-infected individuals have an increased risk of developing malignant lymphoma, and the HBV infection rate in lymphoma patients is significantly higher than that in the general population. However, the exact mechanism and correlation between HBV infection and lymphoma onset and progression currently remain unclear. We retrospectively analyzed clinical data from non-Hodgkin’s lymphoma (NHL) patients with different HBV infection statuses. The results showed that the HBV infection rate was significantly higher in patients with B-cell type and late stage of NHL. The chemotherapy efficacy for NHL patients with chronic active HBV infection was significantly lower than that for the patients with chronic inactive HBV infection, the patients with HBV carriers and the patients without HBV infection. In addition, the NHL chemotherapy activated HBV replication and caused significant liver dysfunction, which could further reduce the chemotherapy efficacy. Through Kaplan-Meier survival curve and log-rank analysis, we found that the HBV infection status in NHL patients was significantly correlated with the patients’ progression-free survival (PFS) and overall survival (OS). Compared with the patients without HBV infection (PFS: 95% CI 47.915 to 55.640; OS: 95% CI 81.324 to 86.858), the PFS and OS of the patients with chronic active HBV infection were significantly shorter (PFS: 95% CI 9.424 to 42.589, P < 0.001; OS: 95% CI 42.840 to 82.259, P = 0.006). The study demonstrated that the sustained HBV replication in patients with chronic active HBV infection could be a key factor that influences the prognosis of NHL patients after chemotherapy, and thus may provide information for designing rational clinical treatments for NHL patients with different HBV infection statuses and improve the treatment efficacy and prognosis.

Abstract
During previous studies of susceptibility to hepatitis B virus (HBV) infection, HBV DNA was detected in 2/6 wild-caught baboons. In the present study, HBV DNA was amplified from 15/69 wild-caught baboons. All animals were negative for HBV surface antigen and antibody against HBV core antigen. Liver tissue from 1 baboon was immunohistochemically negative for HBV surface antigen but positive for HBV core antigen. The complete HBV genome of an isolate from this liver clustered with subgenotype A2. Reverse transcription PCR of liver RNA amplified virus precore and surface protein genes, indicating replication of virus in baboon liver tissue. Four experimentally naive baboons were injected with serum from HBV DNA-positive baboons. These 4 baboons showed transient seroconversion, and HBV DNA was amplified from serum at various times after infection. The presence of HBV DNA at relatively low levels and in the absence of serologic markers in the baboon, a nonhuman primate, indicates an occult infection.

OBJECTIVE To explore influence of sodium restricted diet and non-sodium restricted diet on plasma rennin (PRA), angiotensin II (All), ALD, renal blood flow (RBF) and subside of ascites in patients with cirrhotic ascites. METHODS Eighty cases of hepatitis B with cirrhotic ascites were randomly divided into sodium restricted diet group and non-sodium restricted diet group. 39 cases were in non-sodium restricted diet group, taking sodium chloride 6500-8000 mg daily; 41 cases were in sodium restricted diet group, taking sodium chloride 5000 mg daily. Both groups received diuretics furosemide and spironolactone. Blood sodium, urine sodium, PRA, AII, ALD, RBF ascites subsiding were compared after treatment. RESULTS In non-sodium restricted diet group, blood sodium and urine sodium increased 10 days after treatment compared with those before treatment, and compared with those of sodium restricted diet group 10 days after treatment, P <0. 01. RBF increased compared with that before treatment, and compared with that of sodium restricted diet group 10 days after treatment, P < 0. 01. Renal damage induced by low blood sodium after treatment was less in non-sodium restricted diet group than that in sodium restricted diet group, P <0. 05. Ascites disappearance upon discharge was more in sodium restricted diet group than that in non-sodium restricted diet group, P <0. 01. Time of ascites disappearance was shorter in non-sodium restricted diet group than that in sodium restricted diet group, P < 0. 01. CONCLUSION Compared with sodium restricted diet, while using diuretics of both groups, non-sodium restricted diet can increase level of blood sodium, thus increasing excretion of urine sodium and diuretic effect. It can also decrease levels of PRA, AII and ALD, increase renal blood flow and prevent renal damage induced by low blood sodium and facilitate subsiding of ascites.

Abstract
The mild form of hepatitis A and B with children is attended by a functional activity of pancreatic gland (tripsin), mucous coats of stomach and duodenum (gastrin) which permits to consider them as a factor of the risk of digestive organs combined pathology starting with the disease acuity. Differences in gastrin levels with children depending on hepatitis etiology were specified. Highest levels of gastrin were observed with persons suffering from hepatitis B.

Abstract
OBJECT Autophagy is a lysosomal degradation pathway in which eukaryotic cells dispose intracellular aggregates or defective organelles to maintain cellular homeostasis. Autophagy not only plays a key role in the growth, development, mature and differentiation of cells, but also is associated with pathogenesis, virus infection and immunity. To clarify the mechanism of Hepatitis B virus (HBV) infection and cell immune response, we investigated the relationship between autophagy and IFN factors in the HBV infected cells. METHODS We inhibited the autophagy by the RNA interference knockdown of Beclin1 and Atg7, the essential autophagic genes, examined the number of autophagosomes by fluorescence microscopy and examined the expression of interferon factors by Real-Time PCR. RESULTS Autophagy was inhibited after transfected siBeclin1 or siAtg7. After inhibiting the autophagy, the expression of interferon factors were decreased, but cell apoptosis was not induced. CONCLUSION When the autophagy was inhibited, interferon signaling pathways were impaired in the HBV infected cells. The finding indicated that HBV induced-autophagy enhanced the interferon signaling pathways, and then increased the native immune response.

Abstract
AIMS Hepatitis B virus (HBV) reverse transcriptase (RT) mutants, which have not been well characterized according to different disease stages. This study aimed to characterize the profiles of naturally occurring mutations in the HBV RT region and their associated clinical outcomes. METHODS HBV RT region mutations and genotypes were determined by PCR-direct sequencing and compared with p-distance model. RESULTS Among 467 consecutive eligible patients (262 chronic hepatitis B patients, 105 cirrhotic patients and 100 hepatocellular carcinoma patients), the nucleos(t)ide analogues-related mutations (rtI169T, rtV173L, rtL180M, rtA181T, rtS202C, rtM204I/V, rtN236T) were found. The p-distance value reached a peak in the age of 20-30 years in the CHB patients and in the age of 40-45 years in the cirrhotic patients and hepatocellular carcinoma patients. The naturally occurring mutation, rtS106C mutation was higher in chronic hepatitis B patients (14/100, 14.0%) and cirrhotic patients (14/100, 14.0%) than that in hepatocellular carcinoma patients (4/100, 4.0%, P = 0.013). And the rtD134E/G/N/S mutations were also higher in chronic hepatitis B patients (22/100, 22.0%) and cirrhotic patients (21/100, 21.0%) than that in hepatocellular carcinoma patients (10/100, 10.0%, P = 0.021 and P = 0.032 respectively). The mutation frequencies in A-B interdomain were higher in cirrhotic patients (101/1900, 5.3%) than that in hepatocellular carcinoma patients (68/1900, 3.6%) (P = 0.009). CONCLUSIONS The nucleos(t)ide analogues-related mutations do exist in treatment naive patients with different disease stages. rtS106C, rtD134E/G/N/S and A-B interdomain mutations may be associated with necro-inflammation, immune response and cirrhosis development at ages older than 40.

Abstract
BACKGROUND AND OBJECTIVES Although usually asymptomatic, many chronic hepatitis C patients have extrahepatic manifestations and impaired health-related quality of life (HRQOL), while hepatitis B virus (HBV) patients have normal or nearly normal HRQOL. The aim of this study was to investigate HRQOL in Saudi patients infected with hepatitis C virus (HCV) in comparison with patients infected with HBV in an effort to document the prevalence of and find factors associated with reduced HRQOL in these patients. DESIGN AND SETTING A prospective study that enrolled patients attending a tertiary care referral hepatology clinic in Riyadh from the period of February to July 2008. PATIENTS AND METHODS Consecutive patients who had a confirmed diagnosis of hepatitis C or hepatitis B were asked to fill out the SF-36 questionnaire. Information on epidemiological, educational, economic, and social parameters was collected. All clinical, laboratory, and available histological data were recorded. RESULTS Two hundred and twenty patients (107 with hepatitis B and 113 with hepatitis C) satisfied the inclusion criteria and participated in this study. Overall, 45% were men, and the average age was 41.6 (18.1) years. Patients with HCV had significantly lower scores in "physical functioning," "role limitations due to physical functioning," "social functioning," and "bodily pain." No significant differences in other parameters were observed. Various epidemiological and laboratory parameters were correlated with different HRQOL domains. CONCLUSIONS Saudi hepatitis C patients showed significantly lower HRQOL scores in various domains compared to hepatitis B patients.

Abstract
rs12979860 in interleukin 28B (IL28B) gene is associated with response to interferon-α therapy and natural viral clearance in hepatitis C. The role of this polymorphism is less known in hepatitis B virus (HBV) infection. We evaluated whether rs12979860 was associated with outcomes of HBV infection. There were 651 individuals with persistent infection (387 with liver cirrhosis, 264 without cirrhosis) and 226 healthy individuals who recovered from HBV infection. The genotypic distributions were compared between different phenotypes pertaining to disease progression and HBV markers. The polymorphism had no association with clearance of hepatitis B surface antigen and hepatitis B e antigen, HBV-DNA level, apparent hepatitis onset and liver cirrhosis (P > 0.05). These results suggest that rs12979860 does not have such a strong effect in hepatitis B compared to hepatitis C.
