Methods: Relevant RCTs were searched through March 2019. Data were analyzed by Stata 15.0. Results: Nine articles involving 726 patients were enrolled in this study. Meta-analysis showed that the total effective rate [OR = 3.68 (2.44, 5.55), P < 0.001], Scr [SMD =-2.34 (-3.49,-1.19), P < 0.001], BUN [SMD =-1.80 (-2.73,-0.87), P < 0.001], Ccr [SMD = 0.71 (0.44, 0.97), P < 0.001] were better in the experimental group. But there were no significant difference in UA, CysC, 24h-Upro and incidence of adverse reactions (all P > 0.05) between two groups. No serious adverse reactions were found. Conclusions: The effect of the integrated medicine on CRF was better than Alprostadil alone. Uremic clearance granule is safe and has no obvious adverse reactions.展开更多

Methods： In vivo study, 50 Sprague Dawley rats were divided into three groups： a sham operation group （n=10）, a UUO group （n=20）, and a UUO with UCG treatment group （n=20）. The UCG was given at a dose of 4.5 g/kg body weight per day by gavage after surgery. In vitro study, HK-2 cells were cultured in 10% fetal bovine serum （FBS）, 10% healthy rat serum, 10% FBS and TGF-13 1 （10 ng/mL）, 10% healthy rat serum and TGF-13 1, or 10% rat serum containing the uremic clearance granule and TGF-13 1. The expression of the epithelial marker E-cadherin and the mesenchymal markers vimentin and e^-smooth muscle actin （ot-SMA） in kidney tissues and HK-2 cells were investigated by Western blot analysis and immunofluorescence staining. Results： The rats of the UUO group showed obvious tubulointerstitial fibrosis, compared with the sham operation group rats. Tubulointerstitial fibrosis score was reduced by 17.5%± 1.1% at day 7 and by 20.0%_＋ 1.2% at day 14 in the UCG-treated group, compared with the UUO group. The UCG could maintained expression of E-cadherin and suppressed expression of vimentin and α-SMA in kidney tissues of UUO rats at days 7 and 14, as determined by Western blot analysis and immunofluorescence staining. Rat serum containing the UCG partially inhibited TGF- β 1-induced fibroblast phenotype of HK-2 cells and maintained the epithelial morphology of HK-2 cells in vitro. This occurred partially through a reduction of vimentin expression and an increase of E-cadherin expression. Conclusion： These results suggest that the UCG prevents tubular EMT and may be a promising agent for treating tubulointerstitial fibrosis.展开更多
