Abstract:Objective: To observe the clinical efficacy of Yiqi Huoxue decoction on patients with diabetic kidney disease with Qi and Yin deficiency and blood stasis syndrome, in order to explore its mechanism from the perspective of micro-inflammatory. Method: A randomized, parallel-controlled clinical trial was conducted. A total of 70 patients of diabetic nephropathy with Qi and Yin deficiency and blood stasis syndrome were randomly divided into control group (34 cases) and treatment group (36 cases) according to the random number table. The two groups of patients were given basic treatment (including control diet, blood glucose, blood pressure, lipids) and traditional Chinese medicine. The treatment group was given Yiqi Huoxue decoction for 12 weeks, while the control group was given DM120 formula. Before and after treatment, the patients' serum creatinine, urea nitrogen, serum albumin, urinary albumin/creatinine ratio, serum C-reactive protein (CRP) and interleukin-8 (IL-8) were detected. Result: In treatment group, patients' serum creatinine, urinary albumin/creatinine ratio, serum CRP and IL-8 decreased (P<0.05, P<0.01); serum albumin and glomerular filtration rate obviously increased (P<0.01) after 12 weeks. At the same time, treatment group was superior to control group in decrease of the urinary albumin /creatinine ratio, increase of serum albumin and inhibition of serum CRP and IL-8 (P<0.05). Conclusion: Yiqi Huoxue decoction can protect the renal function of diabetic kidney disease(DKD) patients, decrease proteinuria, and delay the progress of DKD in the early stage. And its mechanism may be related to inhibition of the levels of inflammatory cytokines, such as CRP and IL-8, which can improve the micro inflammatory state of DKD.
