Abstract:
Objective To explore the effects of Xiaoke Shen'an decoction combined with losartan on renal vascular endothelial function and urine podocyte transmembrane protein level in patients with diabetic nephropathy(DN).Methods One hundred and two DN patients admitted to Wujin Hospital of TCM from March 2022 to December 2023 were selected as the research subjects,and according to the treatment method,they were randomly divided into observation group and control group,with 51 patients in each group.All patients in the two groups were given losartan potassium tablets orally,and patients in the observation group were additionally given self-proposed Xiaoke Shen'an decoction for three months.Traditional Chinese medicine symptom scores of patients in the two groups were evaluated before treatment and three months after treatment according to the Guiding Principles for Clinical Trials of New Chinese Medicines.A 5 mL fasting venous blood sample was collected from patients in both groups before treatment and three months after treatment,respectively.After centrifugation,the serum was obtained,and the levels of serum creatinine(Scr)and blood urea nitrogen(BUN)were measured by using a fully automatic biochemical analyzer.The levels of serum endothelin-1(ET-1),soluble intercellular adhesion molecule-1(sICAM-1),superoxide dismutase(SOD)and malondialdehyde(MDA)were detected by using the enzyme-linked immunosorbent assay.Urine samples were collected from patients in both groups before treatment and three months after treatment,and the levels of urinary albumin and creatinine were detected by using a fully automatic biochemical analyzer;and the urinary albumin-to-creatinine ratio(UACR)was calculated.The levels of podocin and nephrin were measured by using flow cytometer.Results Before treatment,there was no statistically significant difference in restlessness,thinness&overeating,fatigue,and edema scores of patients between the two groups(P＞0.05);three months after treatment,the restlessness,thinness&overeating,fatigue,and edema scores of patients in both groups were significantly lower than those before treatment,and patients in the observation group had significantly lower restlessness,thinness&overeating,fatigue,and edema scores compared to the control group(P＜0.05).Before treatment,there was no statistically significant difference in Scr,BUN,and UACR levels between the two groups(P＞0.05);three months after treatment,the levels of Scr,BUN,and UACR in both groups were significantly lower than those before treatment,and patients in the observation group had significantly lower levels of Scr,BUN,and UACR compared to the control group(P＜0.05).Before treatment,there was no statistically significant difference in urinary podocin and nephrin levels between the two groups(P＞0.05);three months after treatment,the levels of urinary podocin and nephrin in both groups were significantly lower than those before treatment,and patients in the observation group had significantly lower levels of urinary podocin and nephrin compared to the control group(P＜0.05).Before treatment,there was no statistically significant difference in serum ET-1 and sI-CAM-1 levels between the two groups(P＞0.05);three months after treatment,the levels of serum ET-1 and sICAM-1 in both groups were significantly lower than those before treatment,and patients in the observation group had significantly lower levels of serum ET-1 and sICAM-1 compared to the control group(P＜0.05).Before treatment,serum SOD and MDA levels showed no statistically significant difference in patients between the two groups(P＞0.05);three months after treatment,the serum SOD levels of patients in both groups were significantly higher than those before treatment,while the serum MDA levels were significantly lower than those before treatment;three months after treatment,the serum SOD level of patients in the observation group was significantly higher than that in the control group,while the serum MDA level was significantly lower than that in the control group(P＜0.05).Conclusion Xiaoke Shen'an decoction combined with losartan can improve renal vascular endothe-lial function,reduce urinary podocin and nephrin levels,and alleviate the stress response in patients with DN.
