The levels of hepatic fibrosis indexes and immune cytokines in serum as well as the number of immune cells in peripheral blood were measured before treatment as well as 3 months and 6 months after treatment.Results: Compared with the corresponding indexes of same group before treatment, serum PC-III, C-IV, TGF-β1, Ang-II and IFN-γ levels as well as peripheral blood Th1 cell number of both groups of patients were significantly lower whereas Th2, mDC and pDC cell number as well as CD80 and CD86 expression intensity in peripheral blood as well as IL-5 and IL-10 levels in serum were significantly higher 3 months and 6 months after treatment;serum PC-III, C-IV, TGF-β1, Ang-II and IFN-γ levels as well as peripheral blood Th1 cell number of experimental group 3 months and 6 months after treatment were significantly lower than those of control group whereas Th2, mDC and pDC cell number as well as CD80 and CD86 expression intensity in peripheral blood as well as IL-5 and IL-10 levels in serum were significantly higher than those of control group.Conclusions: kushenin combined with entecavir treatment of chronic hepatitis B can delay hepatic fibrosis progression and improve immune response.展开更多
