Methods: Forty SPF-grade SD male mice were randomly divided into blank control group, model group, ursodeoxycholic acid group and TCM group, 10 mice in each group. The blank control group was kept normally, and the model group, ursodeoxycholic acid group and TCM group were established as gallbladder distention models. The blank control group and the model group were given 1.5 ml of saline by gavage daily;the ursodeoxycholic acid group was given 100 mg/kg/d of a mixture of saline and ursodeoxycholic acid capsules by gavage daily;the TCM group was given 39 g/kg/d of aqueous decoction of Dahuang Lingxian Prescription by gavage daily. After 6 weeks of continuous intervention, all mice were executed and the lithogenesis rate, ultrastructure and mRNA expression were observed. Results: The lithogenesis rate of mice in the TCM group was significantly reduced (P β1/Smads pathway was significantly improved (P < 0.05), which could achieve the same therapeutic effect as ursodeoxycholic acid capsules. Conclusion: Dahuang Lingxian Prescription can reduce the secretion of “lithogenic bile” by inhibiting the inflammatory reaction and fibrosis of biliary system. Dahuang Lingxian Prescription has certain advantages in the treatment of gallbladder distention.展开更多
