摘要：To explore the effects of Shanxian Giranules (SXG) on diethylnitrosamine (DEN) -inducedprecancerous lesions in rats and its possible molecular mechanism. A total of 50 male SD rats (190+10 g)were randomly divided into five groups. Control group, DEN group, SXG low dose group, SXG medium dosegroup and SXG high dose group. The control group received saline injection. The precancerous liver crthosisgroup received 50mg/kg DEN via intraperitoneal injection twice a week for 16 weeks. The indexes of liverfunction (ALT, AST and GGT) were measured by blood sampling. HE staining was used to observepathological changes of liver tissues. The levels of IL-6 and TNFa were measured by ELISA kits. Comparedwith the model group, the high (P<0.01) and middle dose (P<0.05) of SXG significantly reduced the damageof liver function and ameliorated the degree of liver disease, such as hepatic fibrosis. In addition, SXGsignificantly decreased the levels of IL-10 and TNFa in the liver of DEN-induced precancerous lesions. Inconclusion, SXG can effectively and dose-dependently alleviate the morphological changes of rat liverprecancerous lesions. And the underlying protective mechanism of SXG may be by inhibiting the release ofinflammatory mediators, such as IL-6 and TNF-a.
