Effects of Xuesaitong soft capsule on complement-inflammation receptor system in patients with type 2 diabetic nephropathy / 中国药房

ABSTRACT

OBJECTIVE To observe the effects of Xuesaitong soft capsule on the complement-inflammatory receptor system in patients with type 2 diabetic nephropathy. METHODS A total of 92 patients with type 2 diabetic nephropathy were divided into control group and observation group by random number table method ，with 46 cases in each group. Patients in the control group were given basic treatment programs （including low-salt and low-protein diet ，quitting smoking and alcohol ，appropriate exercise ， lowering blood pressure ，blood sugar and lipid ，etc.）. The patients in the observation group took Xuesaitong soft capsules orally on the basis of the treatment of the control group ，0.55 g each time ，3 times a day. The treatment course of both groups was 4 weeks. Compare the renal function of the two groups of patients [24 h urine protein quantification ，serum creatinine （Scr），blood urea nitrogen，glomerular filtration rate （GFR）]，fasting blood glucose ，glycosylated hemoglobin ，complement factors [C3，C5， complement factor H （CFH），C5b-9]，inflammatory factors [interleukin 1（IL-1），tumor necrosis factor α（TNF-α），IL-6，monocyte chemoattractant protein- 1（MCP-1）]，renal tubular injury markers [β2-microglobulin（β2-MG），retinol binding protein 4（RBP4）， neutrophil gelatinase associated lipocalin] levels；correlation between renal tubular damage and complement-inflammatory receptor system was analyzed in the observation group before and after treatment. RESULTS Compared with before treatment ，24 h urine protein quantity ，Scr，C3，IL-1，TNF-α，MCP-1，β2-MG and RBP 4 of 2 groups were reduced significantly after treatment ，while GFR and CFH were significantly increased ；except for C 3，the observation group was significantly better than the control group （P＜ 0.05）. C 5 of the observation group was significantly decreased after treatment and was significantly lower than the control group （P＜0.05）. There were no statistically significant 60979837。E-mail：shanght126@126.com differences in other indicators of the two groups before and after treatment and between groups （P＞0.05）. C 3，MCP-1 and TNF-α were significantly correlated with renal tubular com damage （P＜0.05），and esp ecially C 3. CONCLUSIONS Xuesaitong soft capsule can reduce renal tubular damage in patients with type 2 diabetic nephropathy and improve renal function by acting on the complement system and reducing inflammation.
