A mouse model for acute hepatitis B virus (HBV) infection was established by using the hydrodynamical injection of mouse tail vein, in which the immunocompetent BALB/c mice were hydrodynamically injected with a competent replication plasmid pAAV-HBV1.2 having 1.2 fold over-length of HBV DNA. On day 1, 2, 4, 6 and 8 after injection, the levels of HBsAg, HBeAg and HBV DNA in blood serum were detected by using ELISA and fluorogenic quantitative PCR assay (FQ-PCR). And on day 8. HBsAg and HBeAg in liver tissue were assayed by immunohistochemical staining. It was found that HBsAg in blood serum could be detected on day 1 after infection in 14 of 16 mice (85.7%) injected with pAVV-HBV1.2 by using ELISA assay and the peak levels of HBsAg and HBeAg were attained during the first day after injection and then it dropped down gradually up to day 8 following injection. The titer of HBV DNA in blood serum attained its peak on day 2 and maintained a high level later on. On day 8 after injection, its titer was 1.9×10~4 copies/mL. The percentage of HBcAg-positive hepatocytes and HBsAg-positive hepatocytes in liver tissues were 5% and 2% respectively. Thus, by using the hydrodynamic injection with the competent replication plasmid, a mouse model for acute HBV infection is successively developed.

Objective: To investigate the effect of matrine (Ma) on telomerase activity and cell cycle in hepatoma cell line HepG 2 cells. Methods: TRAP ELISA method was used to determine the telomerase activity in HepG 2 cells which were treated with different concentrations of Ma. Plasmid inserted with 800 bp of the human telomerase reverse transcriptase (hTERT) promoter was transiently transfected into HepG 2 cells by lipofect. Different concentrations of Ma were added into culture media 2 h later, and the activity of the hTERT promoter was tested 48 h after transfection. In addition, the percentages of HepG 2 cells in different cell cycle were determined by the flow cytometry on the 24, 48 and 72 h respectively after adding the different concentrations of Ma. Results: The telomerase activity of HepG 2 was suppressed by Ma at the dose of 750 ?g/ml and the expression of hTERT promoter was also inhibited. The percentage of G 0/G 1 stage cells increased and the percentage of S and G 2/M stages cells decreased in both 500 ?g /ml and 750 ?g /ml groups 48 and 72 h after Ma was added. Conclusion: Ma may have inhibitory effect on hTERT promoter expression, which is related to the telomerase activity and cell cycle regulation.
