High content screening(HCS) analysis is an advanced technique in the era of systematic biology,which can comprehensively reflect the changes of cell with live,dynamic,and multiparametric characters.It is a good tool to study the complex ingredients and mechanism of traditional Chinese medicine(TCM).Application of the technique would contribute to the discovery of effective ingredients,elucidation of mechanism,and development of TCM theory.

To investigate the effects and characteristics of Fuzheng Huayu recipe, a compound Chinese herbal medicine, and its decomposed therapies against hepatocyte apoptosis in mice with hepatic injury.

OBJECTIVETo investigate the effects of Fuzheng Huayu recipe and Huangqi tang on DMN-induced experimental liver cirrhosis in rats and explore the therapeutic characteristics of Buxu herbals on liver cirrhosis.

METHODLiver cirrhosis in rats was induced by intraperitoneally injection of DMN for 4 weeks. Cirrhotic rats were randomly divided into 4 groups: model group, and Fuzheng Huayu recipe group, Huangqi tang group, Fuzheng Huayu recipe combined with Huangqi Tang group. The rats in treatment groups were orally administered with Fuzheng Huayu recipe, Huangqi tang, Fuzheng Huayu recipe combined with Huangqi tang (1:1), respectively. Normal and model control rats were given the equivalent normal saline. The body weight, liver weight and spleen weight were observed when rats were sacrificed. Liver histology was examined by HE staining and Sirius red staining. The liver function parameters including ALT, T. Bil and Alb were determined. The SOD activity and MDA content in liver tissues were also measured. Hepatic hydroxyproline (Hyp) content was determined by Jamall's method. The expression of alpha-SMA was determined by both immunohistochemistry staining and western blot method.

RESULTCompared with normal rats, the serum ALT and T. Bil levels in model rats increased obviously, by contrast, the serum Alb level decreased. There was a significant decline of SOD activity in model rat liver tissue, while the content of MDA and Hyp increased remarkably. A severe deterioration of liver architecture, infiltration of inflammatory cells and deposition of collagen were observed in model rat liver tissue. The expression of alpha-SMA also increased significantly. Compared with model rats, the liver function, lipid peroxidation parameters, Hyp content and liver histology were all improved in the 3 treatment groups. The combined group is better than any single-use group in decreasing collagen deposition and expression of alpha-SMA.

CONCLUSIONFuzheng Huayu recipe, Huangqi tang, Fuzheng Huayu recipe combined with Huangqi tang can attenuate liver fibrosis in DMN induced rats. Fuzheng Huayu recipe combined with Huangqi tang is better than that using alone in decreasing collagen deposition. The mechanism is partially due to the better effect of Fuzheng Huayu recipe combined with Huangqi tang on inhibiting activated HSC.
