Objective: To observe therapeutic effect of the method for tonifying the kidney and soothing the liver on impotence. Methods: 80 cases of impotence were randomly divided into a treatment group treated by Bushen Shugan Pills and a control group treated by Jingui Shenqi Pills. They were treated for 3 months and the International Erection Index Functional (IIEF-5)was determined at the end of 0,1,2,3 months after administration. Results:The total effective rate was 77. 5% in the treatment group and 52. 5% in the control group with a significant difference between the two groups (P

This study was aimed to observe the effect ofJian-Zhong-Li-Lao(JZLL) decoction-mediated serum on the TGF-β1-induced proliferation of HBZY-1 cells, the expression of matrix metalloproteinases and its inhibitory enzyme, in order to investigate the mechanisms of JZLL decoction in treatment of the renal fibrosis of chronic renal failure. HBZY-1 cells were culturedin vitro. JZLL decoction-mediated serum was prepared. The experiment contained the blank control group, TGF-β1-induced group, control serum group, low-dose JZLL decoction group, high-dose JZLL decoction group, and theNiao-Du-Qinggroup. The cytotoxic effects of JZLL decoction-mediated serum on HBZY-1 cells were assessed by LDH assay. The morphology and proliferation of HBZY-1 cells were examined by CCK8 assay. The expression of matrix metalloproteinases (MMP-2, MMP-9) and its inhibitory enzymes (TIMP-1, TIMP-2) were examined by ELISA assay. The results showed that there was no cytotoxic effect of JZLL decoction-mediated serum on HBZY-1 cells (P > 0.05). Compared with the model group, JZLL decoction can obviously inhibit TGF-β1-induced proliferation of HBZY-1 cells (P < 0.05). JZLL decoction can obviously increase the expressions of MMP-2 and MMP-9 (P < 0.05), and inhibit the expressions of TIMP-1 and TIMP-2 (P < 0.05). It was concluded that JZLL decoction-mediated serum significantly inhibited TGF-β1-induced proliferation of HBZY-1 cells, relieved the renal fibrosis of chronic renal failure through affecting the expression of matrix metalloproteinases and its inhibitory enzymes.
