Diabetic nephropathy is a renal complication of diabetes mellitus that develops over time and is characterized clinically by proteinuria and edema. The disease is located in the kidney and can subsequently affect the heart, liver, spleen and other organs. The pathogenesis is characterized by Yin deficiency in the early stage of the disease, involving the liver and kidney; in the middle stage of the disease, the spleen and kidney Yang deficiency; in the late stage of the disease, the kidney Yang decay, resulting in serious dysfunction of human tissues and organs. Among them, qi deficiency and blood stasis run through the development of diabetic nephropathy. According to the early, middle and late stages, our department mostly uses some empirical prescriptions to treat. (1) Early stage is mostly liver and kidney qi and yin deficiency, we mostly use Astragalus, leech, rhubarb, Cornu Cervi Pantotrichum, prunus ginseng, smallpox powder, maitong, motherwort, blood stasis and other herbal medicines to treat.
