Liver transplantation is the only possible treatment for those who advance to end-stage liver disease. Donors positive for hepatitis B virus(HBV) core antibody(HBc Ab) have previously been considered unsuitable for transplants. However, those who test negative for the more serious hepatitis B surface antigen can now be used as liver donors, thereby reducing organ shortages. Remarkable improvements have been made in the treatment against HBV, most notably with the development of nucleoside analogues(NAs), which markedly lessen cirrhosis and reduce post-transplantation HBV recurrence. However, HBV recurrence still occurs in many patients following liver transplantation due to the development of drug resistance and poor compliance with therapy. Optimized prophylactic treatment with appropriate NA usage is crucial prior to liver transplantation, and undetectable HBV DNA at the time of transplantation should be achieved. NA-based and hepatitis B immune globulin-based treatment regimens can differ between patients depending on the patients' condition, virus status, and presence of drug resistance. This review focuses on the current progress in applying NAs during the perioperative period of liver transplantation and the prophylactic strategies using NAs to prevent de novo HBV infection in recipients of HBc Ab-positive liver grafts.展开更多

METHODS： Four HBV promoters were amplified by polymerase chain reaction （PCR） and subcloned into the expression vector pEGFP-1. The four recombinants controlled by HBV promoters were confirmed by restriction analysis and sequencing. Human hepatoma HepG2 cells transfected with the recombinant plasmids were treated with various concentrations of β-L-D4A and β-LPA. Then, enhanced green fluorescent protein （EGFP）-positive cells were detected by fluorescence microscopy and using a fluorescence activated cell sorter RESULTS： Four HBV promoters were separately obtained and successfully cloned into pEGFP-1, Expression of EGFP under the control of the surface promoter （Sp） and the X promoter （Xp） was inhibited by β-L-D4A in a dosedependent manner, while expression of EGFP under the control of the core promoter （Cp） and Xp was inhibited by β-LPA in a dose-dependent manner. CONCLUSION： The two novel nucleoside analogues investigated here can inhibit the activities of HBV promoters in a dose-dependent manner. These findings may explain the mechanisms of action by which these two novel compounds inhibit HBV DNA replication.展开更多

Methods: Patients with chronic hepatitis B who received antiviral therapy in Infectious Diseases Hospital of Shanghai Huangpu District between April 2014 and October 2016 were selected as the research subjects and divided into 3 groups, group A received entecavir therapy, group B received adefovir dipivoxil therapy and group C received lamivudine therapy. 24 weeks and 48 weeks after treatment, the levels of liver fibrosis indexes in serum as well the levels of DC and the expression of surface markers in peripheral blood of the three groups were measured respectively. Results: After treatment, serum hyaluronic acid (HA), procollagen III (PC-III), laminin (LN) and collagen type IV (C-IV) levels of all groups were significantly lower than those before treatment, and the number of myeloid DC (mDC) and plasmacytoid DC (pDC) in peripheral blood as well as the expression levels of DC surface molecules CD80, CD86, CD1αand HLA-DR in peripheral blood were significantly higher than those before treatment. After treatment, the serum levels of HA, PC-III, LN and C-IV in group A were significantly lower than those in group B and C, and the number of mDC and pDC in peripheral blood as well as the expression of DC surface molecules CD80, CD86, CD1α and HLA-DR in peripheral blood were significantly higher than those in group B and C. Conclusion: Antiviral therapy by nucleoside analogues can effectively inhibit liver fibrosis and improve peripheral blood DC function in patients with chronic hepatitis B, and Entecavir function is better than that of adefovir dipivoxil and lamivudine.展开更多
