  • THE MOLECULAR MECHANISM OF HBx IN THE CARCINOGENESIS OF HEPATITIS B VIRUS RELATED HEPATOCELLULAR CARCINOMA

    Objective To understand the molecular mechanism of HBx in the carcinogenesis of hepatitis B virus (HBV) related hepatocellular carcinoma (HCC).Methods The literatures published in the past 5 years which are mainly about HBx and hepatocellular carcinoma were reviewed. Results HBx had many functions, such as cell malignant transformation, inhibiting DNA repair, trans-activation, inhibiting p53 and apoptosis. These functions together with its Fas/Fas-L interfering and caspase-3 inhibiting could contribute to the carcinogenesis and development of HBV relatde HCC. Conclusion HBx has broad spectrum of biological functions, which contribute to the carcinogenesis and development of HBV related HCC.

  • Value of HBV Pre-S1Ag Tested by Enzyme-linked Immunosorbent Assay in Diagnosis of Hepatitis B Virus Replication: A Meta-Analysis

    ObjectiveTo systematically review the diagnostic value of HBV Pre-S1Ag tested by enzyme-linked immunosorbent assay (ELISA) in patients with hepatitis B virus replication. MethodsSuch databases as PubMed, EMbase, The Cochrane Library (Issue 3, 2014), CBM, CNKI, VIP and WanFang Data were electronically and comprehensively searched for relevant studies on the diagnostic value of HBV Pre-S1Ag tested by ELISA in patients with hepatitis B virus replication from inception to May 1st, 2014. Relevant journals were also manually retrieved. Two reviewers independently screened literature according to inclusion and exclusion criteria, extracted data, and assessed methodological quality of included studies. Meta-analysis was then conducted using Meta-Disc 1.4 software. ResultsFinally, fifteen studies were included, involving 1 994 patients with hepatitis B diagnosed by the gold standard and 526 patients with non-hepatitis B diseases. The results of meta-analysis showed (Sen=0.76, 95%CI 0.74 to 0.78; Spe=0.90, 95%CI 0.88 to 0.91; +LR=8.54, 95%CI 4.25 to 17.15;-LR=0.17, 95%CI 0.10 to 0.27; DOR=65.12, 95%CI 24.91 to 170.28; AUC=0.943 0, SE=0.018 1; Q*=0.881 3, SE=0.023 4). ConclusionHBV Pre-S1Ag tested by ELISA has certain value in the diagnosis of patients with hepatitis B virus replication. Due to poor methodological quality of the included studies, the above conclusion should be verified by conducting high quality diagnostic tests.

  • Research progress of biomarkers of hepatitis B virus and clinical significance

    The infection of Hepatitis B virus (HBV) can result in severe consequences, including chronic hepatitis, liver fibrosis, cirrhosis, and even liver cancer. Effective antiviral treatment has the potential to slow down the progression of the disease. HBV serum biomarkers play a crucial role in the dynamic management of chronic hepatitis B (CHB) patients. However, the conventional hepatitis B virus markers, such as hepatitis B serologic testing and HBV DNA, are insufficient to meet the clinical requirements. This review provided a comprehensive overview of the current research on the quantification of HBsAg and anti-HBc, HBV RNA and HBV core-associated antigen, which summarized the crucial role these markers play in the administration of antiviral medications, predicting the efficacy of treatment and anticipating the likelihood of virologic rebound following drug cessation, as well as assessing disease progression in CHB patients.

  • Sophorus for chronic hepatitis B virus infection: protocol of a systematic review

    Background Hepatitis B is one of the major infectious diseases of mankind, and up to now, there is no effective way to handle it. Recent clinical trials have shown the potential advantages of Kurorinone an extract of Chinese herb, in treament of chronic HBV infection. Objectives Systermically review the safety and efficacy of Kurorinone in treatment of chronic HBV infection. Search strategy With the searching terms including Kurorinone, its products’ name, hepatitis B and chronic carrier status, the trials registers of the Cochrane Hepato- Biliary Group, the Cochrane Complementary Medicine Field, and the central database of the Cochrane Library as well as MEDILINE, EMBASE and Chinese Biomedical CD Database were searched from their date of inception onward. 20 Chinese medical journals and relevant academic conference proceedings have been searched by hand. The reference lists of identified documents were checked as the complementary search. Inclusion Criteria All RCTs that tested Kurorinone for chronic HBV infection were included in this review. Method of the review According the demand of Cochrane systematic review, selection of trial for inclusion, assessment of methodological quality, data extraction and data syntheses would be conducted for each included trial.

  • Effectiveness and Safety of Foscarnet Sodium in Treating Chronic HBV Hepatitis: A Systematic Review

    Objective To evaluate the effectiveness and safety of foscarnet sodium in the treatment of chronic hepatitis B. Methods We searched MEDLINE, EMbase, The Cochrane Library and CNKI from 1978 to June 2006. Randomized controlled trials of foscarnet sodium versus other drugs or no drugs in the treatment of chronic hepatitis B were identified. The quality of the included trials was evaluated by two reviewers independently. Meta-analysis was done using The Cochrane Collaboration’s RevMan 4.2.7. Results Seven studies (337 patients) were included; one compared foscarnet sodium versus interferon, and the other six compared foscarnet sodium versus no drugs. All the included studies were graded in terms of the quality of randomization, allocation concealment and blinding. All 7 studies were graded as level C. The meta-analysis showed that: ① foscarnet sodium was not significantly different from interferon in clinical efficacy, liver function, negative-conversion rate of virological markers and side effects. ② compared with the no drugs group, the negative-conversion rate of virological markers was significantly higher for the foscarnet sodium group, HBeAg (RR 6.20, 95%CI 1.76 to 21.79) and HBV-DNA (RR 4.13, 95%CI 1.32 to 12.86); but there were no significant differences in clinical efficacy, liver function and side effects. Conclusions Available evidence shows that: in the treatment of chronic hepatitis B the effectiveness and safety of foscarnet sodium are not significantly different from interferon, but only one trial is included in this review, so the evidence is weak. Compared with no drugs, foscarnet sodium significantly improves the negative-conversion rate of virological markers, but the evidence is insufficient to show whether foscarnet sodium could improve clinical efficacy and liver function, as well as reduce side effects.

  • Prophylactic Effect of Lamivudine Monotherapy Against Hepatitis B Recurrence Following Liver Transplantation

    【Abstract】ObjectiveTo investigate the prophylactic effect of lamivudine monotherapy on the recurrence of hepatitis B after liver transplantation. MethodsThirtyone patients with hepatitis B related benign decompensated cirrhosis who underwent liver transplantation between February 1999 to June 2002 and survived more than 3 months were analyzed retrospectively. Lamivudine was administered to each patient after operation and some patients before operation for the prophylaxis of HBV recurrence. The HBV markers and HBV DNA in serum and bioptic liver tissues in all patients were evaluated before and after operation. ResultsTotal HBV recurrence rate was 19.4%(6/31) during average 38.2 months (3.2-70.2 months) follow up. HBV recurrence rate was 7.1%(2/28), 16.0%(4/25), 26.1%(6/23) and survival rate was 87.1%(27/31), 80.6%(25/31), 66.1%(20.5/31) after 1-, 3-and 5-year, respectively. One hundred milligram lamivudine administration peroral daily for 2 weeks prior to transplantation enable HBeAg 54.5%(6/11) and HBV DNA 50.0%(5/10) positive patients convert to negative respectively. ConclusionPreoperative administration of lamivudine monotherapy can effectively prevent allograft from HBV re-infection after liver transplantation. Lamivudine should be used to convert HBV DNA and HBeAg to negative.
