In this way, we built a rat model of CCl4-induced hepatic fibrosis with intervention by vitamin D, puerarin, or a combination of the two. After eight weeks, the mice were sacrificed to collect serum and liver specimens. Blood was collected to detect the hyaluronic acid(HA). We also measured hydroxyproline(Hyp) and prepared paraffin sections of liver. After Sirius red staining, the liver specimens were observed under a microscope. RT-PCR and western blot analysis were adopted to detect the mRNA and the proteinlevels of Collagen I, Collagen III, Wnt1, and β-catenin in the liver tissues, respectively.RESULTS Hepatic fibrosis was observed in the CCl4 group. In comparison, hepatic fibrosis was attenuated in the V, P, and V + P groups: the HA level in blood and the Hyp level in liver were reduced, and the mRNA levels of Collagen I, Collagen III, Wnt, and β-catenin in liver were also decreased, as well as the protein levels of Wnt1 and β-catenin. Among these groups, the V + P group demonstrated the greatest amelioration of hepatic fibrosis.CONCLUSION The combined application of vitamin D and puerarin is capable of alleviating CCl4-induced hepatic fibrosis of rats. As to the mechanism, it is probably because the combined use is able to silence the Wnt1/β-catenin pathway, suppress the activation of hepatic stellate cells, and reduce the secretion of collagen fibers, therefore improving the anti-hepatic fibrosis effect. 关键词：Carbon TETRACHLORIDE HEPATIC FIBROSIS VITAMIN D PUERARIN WNT/Β-CATENIN
