Abstract

Objective： To study the effects of Rougan Formula on interleukin-22 （IL-22） secretion and IL-22 receptor 1 （IL-22R1） expression in the liver of concanavalin A （ConA） combined with 3,5-diethoxy carbonyl-1,4-dihydro-2,4,6-trimethylpyridine （DDC） induced liver fibrosis mice， and to explore the mechanism of Rougan Formula against liver fibrosis.,Methods,2,Sixty mice were randomly divided into control group， model group and Rougan Formula group， with 20 mice in each group. The mice in the model group and Rougan Formula group were injected with ConA through the tail vein once a week and fed with DDC diet. The mice in the control group were injected with equal volume of 0.9% NaCl solution through the tail vein and fed with normal diet. The mice in Rougan Formula group were given Rougan Formula granules by gavage （8.5 g/kg） once a day. The mice in control and model group were given equal volume of 0.9% NaCl solution by gavage. The Drug intervention lasted for 10 weeks. The mice were killed after 10 weeks， liver function， secretion of IL-22 and expression of IL-22R1 in liver were observed.,Results,2,①Compared with the control group， the expression of, IL,-,22，,IL,-,22R1,， ,IL,-,10R2, and ,STAT3, mRNA in the liver of mice in the model group and Rougan Formula group significantly increased （,P,<,0.01，,P,<,0.001）. Compared with the model group， the expression of ,IL,-,22, and ,IL,-,10R2, mRNA in the liver of mice in the Rougan Formula group significantly increased （,P,<,0.001）. ②Compared with the control group， the expression of ,IL,-,22R1, mRNA on the surface of hepatic stellate cells （HSCs） in the model group significantly increased （,P,<,0.05）， the expression of ,STAT3, mRNA in HSCs significantly increased （,P,<,0.05）， the expression of, IL,-,22R1, and ,IL,-,10R2, mRNA on the surface of HSCs in the Rougan Formula group significantly increased （,P,<,0.05，,P,<,0.001）， and the expression of ,STAT3, mRNA in HSCs in the Rougan Formula group significantly increased （,P,<,0.001）. Compared with the model group， the expression of ,IL,-,22R1, mRNA on the surface of HSCs and ,STAT3, mRNA in HSCs in the Rougan Formula group significantly increased （,P,<,0.01，,P,<,0.001）. ③Compared with the control group， the number of Th22 cells in the model group and Rougan Formula group significantly increased （,P,<,0.001）. Compared with the model group， the number of Th22 cells in the Rougan Formula group significantly increased （,P,<,0.01）.,Conclusion,2,Rougan Formula can increase the secretion of IL-22 in the liver and the expression of IL-22R1 on the surface of HSCs， so as to play the role of anti-hepatic fibrosis.
