Objective:To observe the effect ofRouganHuaqian granules combined with human mesenchymal stem cell(hMSC) transplantation on the liver fibrosis in carbon tetrachloride-induced cirrhosis rats.Methods:SixtySD rats were randomly divided into five groups.The rats in control group received intraperitoneal injection of saline, while those in model control group, treatment groupA, groupB and groupC received intraperitoneal injection of carbon tetrachloride oily solution to induce liver cirrhosis within8 weeks.Then, the rats in the model control group, treatment groupA, treatment groupB, treatment groupC received vein tail injection of saline, RouganHuaqian granules, hMSC suspension andRouganHuaqian granules combined with hMSC suspension.Results:The treatment groups had significantly different liverfunction(AST levels), liver fibrosis index(laminin andHA), hepatic sinusoidal wallsα-smooth muscle actin,Ⅳ collagen and laminin protein expression andⅠ,Ⅲ collagen from the model group(P<0.05). The transplanted cells showed human hepatocyte-like cells differentiation trend in the liver. Conclusions:TheRouganHuaqian granules combined with hMSC transplantation can alleviate liver fibrosis in cirrhosis rats.
