    Abstract:
    OBJECTIVE: To study the effect of Astragalus and Salvia's effective components and their compatibility on JAK/STAT pathway of rats' renal fibrosis. METHODS: 66 SD rats were randomly divided into 7 groups: normal group,model group,fosinopril group, salvianolic acids group, astragalus saponins group, granules compatibility of Astragalus and Salvia group, components combination of Astragalus and Salvia group. The variation of beta2-microglobulin(beta2-MG), the changes of renal pathology and JAK/STAT pathway were observed. RESULTS: The changes in renal pathology of treatment groups had different degrees of improvement; Astragalus and Salvia could reduce the urinary beta2-MG of unilateral ureteral obstruction (UUO) rat (P < 0.05), which was equal with fosinopril group. The rest of the treatment groups decreased especially fosinopril group while the difference was not significant when compared with the model group. Astragalus and its effective components could reduce the expression of renal tissue JAK, STAT1, STAT3 protein, among which fosinopril group and granules compatibility of Astragalus decreased significantly. Astragalus saponins group was not obvious, and the rest of the treatment group had significantly minor effect. CONCLUSION: Astragalus and Salvia's effective components and their compatibility may protect renal tubular function in unilateral ureteral obstruction, which may interfere with UUO rat kidney with JAK/STAT signaling pathway.
