Abstract:Objective To investigate the effect of Xiaoyuxiezhuoyin on serum leptin (LP) in diabetic patients with CKD3-5 renal failure. Methods Totally 80 diabetic patients with CKD3-5 renal failure were randomly divided into observation group and control group (n = 40). All patients were treated with standard medical therapy. Patients in observation group received additional Xiaoyuxiezhuoyin (1 dose per day for 3 months). Concentration of LP was measured priorpre to and post treatment. Main symptom scores were recorded. Results Patients in observation group experienced more dramatical reduction of LP compared with that in control group, though concentration of LP was decreased in control group (P < 0.05). scores of main symptoms and signs in observation group were improved significantly when compared with control group (P < 0.01). Conclusion Xiaoyuxiezhuoyin exerts renal protection in diabetic patients with CKD3-5 kidney failure, alleviating clinical symptoms and progression of renal failure.
