| Abstract_FL | [Objective]People infected with Hepatitis B are often divided into hepatitis B carriers and hepatitis B patients based on whether ALT is normal or not,and ALT ≥ 2UNL is one of the indications for clinical antiviral treatment,but no sufficient evidence to justify this. In order to explore the theoretical basis,the paper investigated the effects of hepatitis B virus(HBV) on hepatic stellate cells(HSCs).[Methods]A total of 132 chronic hepatitis B patients with different viral loads and ALT levels were randomly selected as the study subjects. Of these patients,those with ALT≥2UNL were treated with antiviral therapy and followed up for 24 weeks. The effects of HBV on HSCs before and after the treatment were compared and analyzed. HSCs proliferation was detected by MTT method,HSCs cell cycle by flow cytometry,and expression of TGF-β1,Smad3,Smad7,α-SMA,collagen Ⅰ,collgen Ⅲ mRNAs and corresponding proteins by RT-PCR and Western blotting,respectively.[Results]At the normal ALT level,HBV with different viral loads had no significant effect on the proliferation,cell cycle and cell secretion of the HSCs. At the abnormal ALT level,especially when ALT ≥ 2UNL,with the increase of virus loads,HSCs proliferation accelerated;cells in the G0/G1 phase decreased significantly and cells in the S and G2/M phases increased significantly;the expression of TGF-β1,Smad3,α-SMA,collagen Ⅰ,collgen Ⅲ mRNAs and corresponding proteins increased significantly,but Smad7 mRNA and protein expression decreased significantly,the differences were statistically significant. HBV showed a significantly lower effect on HSCs after the antiviral therapy than before.[Conclusions]This paper reveals the differential effects of HBV on HSCs at different ALT levels and presents a comparative analysis of the effects before and after the antiviral therapy,which provides a theroretical basis for identifying the ALT level as an indication for HBV antiviral therapy. |
