Hepatitis C virus cell entry is mediated by multiple factors,including various receptors and cellular factors that trigger virus uptake by the hepatocyte.Occludin is a newly identified essential co-receptor for HCV entry together with CD81,SR-B1 and CLDN1.CLDN1 and occludin highlight the importance of studying the effects of tight junction and cell polarization on HCV entry.Study on cell polarization and tight junction can help to discover new targets for HCV therapy,and therefore interfere the cell entry and cell-cell spread of HCV.This review summarizes the current knowledge of hepatocyte polarization,tight junction and its major integral proteins CLDN1 and occludin,polarized cell culture system and its relation with HCV entry.

Objective To observe the effects of Haizao Yuhu Decoction on the CXCR 4 expression of TT cell tumor-bearing mice. Methods Culture the human thyroid TT cells in vitro, and inoculate them into 30 healthy mice BALB/C. Subsequently, Haizao Yuhu Decoction was given to the tumor-bearing mice. They are grouped into three groups, including tumor-bearing group (n=10), Haizao Yuhu Decoction high dosage group (n=10) and Haizao Yuhu Decoction low dosage group (n=10) to observe the tumor growth to calculate the anti-tumor rate. After the tumor has been reaped, immunohistochemical is adopted to test the expressions of chemotactic factor receptor-CXCR 4 on protein level. RT-PCR is used to test the expressions of CXCR 4 on genetic level. Results Comparing with the tumor-bearing group, HZYHD high-dosage group has decreased the expressions of CXCR 4 on both the protein and genetic levels, which is to certain degree dependent on concentration.Conclusion Haizao Yuhu Decoction could decrease the expression of CXCR 4.

Objective To evaluate the efficacy and safety of adjuvant IFN therapy for viral hepatitis-related hepatocellular carcinoma(HCC)after treatment with surgical resection or transarterial chemoembolization(TACE).Methods Controlled trials of adjuvant treatment with IFN for patients with HCC published between 2000 and 2012 were searched electronically in MEDLINE,PubMed,Cochrane Library,and EMBASE databases.According to the heterogeneity of the studies,two different models-the fixed-effect model and the random-effect model-were applied to analyze the results. Results Ten trials were screened according to inclusion and exclusion standards.Eight randomized,controlled trials and two non-randomized,controlled trials were included.These ten trials with a total of 1 ,029 subjects were eventually involved in the meta-analysis;528 HCC patients were treated with adjuvant treatment with IFN and 501 patients with placebo.Compared to the control group,the recurrence rates of HCC in IFN group were significantly lower CR=0.66;95% CI=0.50 to 0.86;P=0.02),especially after TACE treatment according to subgroup analysis(OR=0.73;95%CI=0.52 to 1.01;P=0.06 for surgical resection;and OR=0.54;95%CI=0.33 to 0.86,P=0.01 for TACE).The death rates in the IFN group also significantly decreased according to not only total events analysis(OR=0.42;95%CI=0.32 to 0.56;P<0.01)but also subgroup analysis(OR=0.51;95%CI=0.36 to 0.72;P=0.0002 for surgical resection;and OR=0.33;95%CI=0.21 to 0.50;P<0.01 for TACE).Conclusion Adjuvant IFN therapy may significantly reduce the recurrence rates of patients with viral hepatitis-related HCC and improve the survival of patients after surgical resection or TACE.The ideal dose mostly selected is 3 MIU/mL,three times per week,which can make patients tolerate the adverse reactions of IFN better and maintain effective concentrations for a long time.

As highly active anti-retroviral therapy continues, large numbers of drug-resistant strains appeared in human immunodeficiency virus ( HIV) infectors, which always leads to a decline of treatment results or even a treatment failure.The genotypic resistance analysis technique of the bioinformatics is a powerful tool to forecast the HIV resistance and also determines the success or failure of antiviral therapy.This review will be focus on the advantages and disadvantages, influence factor of the genotype resistance prediction and improve measure of the primary HIV drug resistance genotype interpretation system, depending on the principle and characteristics of the genotypic drug resistance analysis as the breakthrough point, in order to provide guidance for reasonable application of different genotypes drug resistance analysis system in China.
