Abstract. The aim of the present study was to investigate the effect of the traditional Chinese medicine (TCM), ʻSpleen-kidney-careʼ Yiqi Huayu and Jiangzhuo decoction (SKC-YJ), as an adjuvant therapy in diabetic nephropathy (DN) treatment. In total, 72 patients with DN were randomly divided into control (n=54) and experimental (n=18) groups, with the latter administered SKC-YJ treatment. Indicators for determining the condition of the patients included the levels of proteinuria, blood glucose, glycosylated hemoglobin, blood lipids, blood viscosity and C-reactive protein, which were used to analyze the treatment protocols for DN. Following SKC-YJ treatment, the urinary albumin excretion rate, fasting blood glucose, 2 h-postprandial blood glucose, glycosylated hemoglobin, triglyceride, total cholesterol, blood viscosity, fibrinogen and C-reactive protein levels were detected in the two groups, and were all demonstrated to decrease significantly following treatment with SKC-YJ. Furthermore, the results revealed that SKC-YJ treatment exhibited no significant side-effects on the blood, liver and renal functions or gastrointestinal reactions. By contrast, SKC-YJ improved the symptoms of nausea, vomiting and diarrhea in the patients with DN, while showing no allergic reaction during the observation period. Therefore, SKC-YJ treatment was shown to significantly improve the clinical efficacy of DN treatment, illustrating novel roles for TCM in DN treatment.
IntroductionAn increasing number of studies have revealed that the incidence of diabetes is based on the relative or absolute deficiency of insulin secretion from islet β-cells, which is caused by high levels of blood glucose (1-3). Diabetes is characterized by chronic, systemic metabolic disorders, while diabetic nephropathy (DN) is a systemic complication of diabetes. DN is a progressive kidney disease caused by angiopathy of the capillaries in the kidney glomeruli (4) and is characterized by nephrotic syndrome and diffuse glomerulosclerosis. DN is one of the most serious, chronic complications of diabetes, seriously affecting the life of patients, and in certain cases, resulting in mortality (5).According to traditional Chinese medicine (TCM) syndrome differentiation typing, DN is classified as a variety of types, including 'Thirsty', 'Consumption' and 'Edema' (6). Specifically, DN is associated with congenital deficiency, diet, emotional disorders, excessive labor and fever. Currently, TCM considers the pathogenesis of DN to be involved in spleen and kidney deficiency. Qi is the driving force of life activities and Yin is the material basis of life activities (7). Damage of Qi is more common in early DN (8), and as the disease progresses, DN gradually causes the damage of Yin (8-10).Disease of the islet β-cells is closely associated with the spleen (11). Modern medicine and TCM considers the kidney to be associated with the nervous, endocrine, reproductive, exercise, breathing, digestion, water metabolism, blood and immune systems, as well as other abnormal physi...
