Objective To understand the virology test characteristics of hepatitis B virus (HBV) for discuss the relation of HBV genotype and HBeAg, anti-HBc-IgM, HBV DNA and disease progression. Methods Two hundred cases of hepatitis B were detected by the ELJSA assay with two pairs of semi-markers (HBsAg, anti-HBs, HBeAg, anti-HBe, anti-HBc) and anti-HBc-IgM, using fluorescence quantitative polymerase chain reaction (FQ-PCR) for detecting HBV DNA, using monoclonal antibody ELISA method (mAbs ELISA) for HBV genotyping and analysis of test results. Results In 200 patients with hepatitis B, the HBV genotype detected in 179 cases (89.5%), B-type 121 cases(60.5%), C-type 58 cases (29.0% ). There had no relationship with HBeAg, anti-HBc-IgM, HBV DNA and genotype. B-type HBV prevalent in asymptomatic carriers (ASC) and chronic hepatitis B (mild);C-type common in patients with liver cirrhosis (LC) and chronic hepatitis B (severe). Conclusions HBV genotype in Shenzhen mainly is B-type, C-type second;mAbs ELISA assay with HBV genotype is specific, sensitive, simple and practical features, HBV replication strength has nothing to do with the virus genotype. HBV genotype and HBeAg, anti-HBc-IgM, HBV DNA testing may complement each other, with the clinical application value.

Objective To explore CD59 expression on CD4+T cells in HIV infected patients and its relationship with apoptosis.Methods 12 HIV infected patients and 10 healthy donors were performed in this study.The PBMC(peripheral blood monocyte)were collected and cell surface cytokine were stained,and then were evaluated with the BD FACSCanto flow cytometry.The expression of CD59 on T lymphocyte subsets were analyzed by FACSDiva software,and the apoptosis rate of CD59+CD4+T cells and CD59-CD4+T cells in every group was analyzed respectively,then the results were compared between groups.Results Compared with healthy donor,the expression of CD59 on T cells in HIV infected patients was significantly hisher(t=5.198,P＜0.01),and the apoptosis rate of CD59+CD4+T cells had significantly higher(t=5.968,P＜0.01).The apoptosis rate of CD59-CD4+T cells was no difference between two groups (t=0.1353,P=0.8577).Condnsion HIV infection increase CD59 expression on CD4+T cells,and CD59+CD4+T cells were prone to apoptosis.
