Objective:To study the clinical efficacy ofYiqi Huoxue Decoction in the treatment of children with spleen and kidney deficiency type nephrotic syndrome.Methods:A total of 80 children with spleen and kidney deficiency type nephrotic syndrome in our hospital from June 2014 to October 2016 were enrolled in this study.The subjects were divided into control group (n=40) and treatment group (n=40) according to the random number table method.The control group was treated with prednisone,and the treatment group was treated with prednisone combined with Yiqi Huoxue Decoction,the two groups were treated for 4 months.The clinical efficacy of the two groups were evaluate.The 24h proteinuria,total cholesterol (TC),plasma albumin (Alb),and renal function parameters including blood urea nitrogen (BUN),serum creatinine (Scr),and serum creatinine clearance (Ccr) of the two groups before and after treatment were compared.Results:The total effective rate of the treatment group was 95.00％,which was significantly higher than 67.50％ of the control group,the difference was statistically significant (P＜0.05).The 24h proteinuria,TC,BUN and Scr of the two groups after treatment were significantly lower than before treatment,the Alb,Ccr of the two groups were significantly higher than before treatment,and above indexes in treatment group were better than the control group,the differences were statistically significant (P＜0.05).Conclusion:Yiqi Huoxue Decoction have good clinical efficacy in the treatment of children with spleen and kidney deficiency type nephrotic syndrome,which can obviously improve children renal function,and is worthy of clinical application.
