Objective

2

This study aims to investigate the clinical effect of addition and subtraction therapy of Zhibai Dihuangwan combined with Wulingsan in the treatment of refractory nephrotic syndrome （RNS） with Yin deficiency of liver and kidney and its regulatory effect on immune inflammatory response.

Method

2

In this study， 108 children were randomly divided into observation group （54 cases） and control group （54 cases）. Patients in two groups were treated with prednisone acetate tablets combined with tacrolimus capsules . Patients in control group took Liuwei Dihuang oral liquid， 5-10 mL/time， twice a day. Patients in control group were prescribed the addition and subtraction therapy of Zhibai Dihuangwan combined with Wulingsan， 1 dose/day. The course of treatment for both groups was 6 months. The 24 h urine total protein （24 h-UTP）， serum albumin （ALB）， serum creatinine （Scr）， blood urea nitrogen （BUN）， total cholesterol （TC）， triglyceride （TG）， low density lipoprotein （LDL）， high density lipoprotein （HDL）， liver and kidney Yin deficiency syndrome score， fibrinogen （FIB），

Conclusion

2

Based on the treatment of hormone combined with Tacrolimus， Zhibai Dihuangwan combined with Wulingsan can reduce urinary protein， improve lipid metabolism disorder and hypercoagulability， and regulate immune inflammatory reaction in patients with RNS and Yin deficiency of liver and kidney， with remarkable comprehensive effect and TCM syndrome effect.
