| 摘要 目的：研究黄芪甲苷 ( Astragaloside IV, AS-IV）联合骨髓间充质干细胞（Bone marrow mesenchymal stem cells, BMSCs）对链脲佐菌素（Streptozocin, STZ）诱导的糖尿病肾病（Diabetic nephrology, DN）大鼠肾脏的保护作用。方法：8周龄正常雄性 SD（Sprague Dawley, SD）随机选取8只作为正常对照组，其余大鼠给予腹腔注射60 mg/kg剂量STZ建立糖尿病模型。造模成功的大鼠随机分为模型组、BMSCs组和BMSCs + AS-IV组，每组8只。BMSCs+AS-IV组给予AS-IV口服灌胃治疗。BMSCs组与BMSCs+AS-IV组给予尾静脉注射BMSCs，正常对照组和模型组尾静脉注射相同剂量的无血清DMEM培养基。于第10周末收集大鼠24小时尿液，并留取肾脏组织，测定24 h尿白蛋白排泄，观察肾脏病理改变，并采用免疫组织化学方法检测肾组织中α-SMA、Desmin、Nephrin、NOX4的表达。结果：与模型组相比，BMSCs组与BMSCs+ AS-IV组大鼠的肾脏病理损伤明显改善，肾小球系膜细胞增生，系膜基质增多；肾组织中NOX4、Desmin和α-SMA蛋白表达降低，Nephrin蛋白表达增加，24 h尿白蛋白排泄均明显减轻，且BMSCs联合AS-IV治疗组效果更显著（P＜0.05）。结论：AS-IV联合BMSCs治疗可缓解糖尿病肾病大鼠肾脏病理损伤，改善DN大鼠肾组织的氧化应激，改善肾脏足细胞转分化，从而减轻蛋白尿排泄，具有肾脏保护作用。 |

| ABSTRACT Objective: To study the renal protective effect of Astragaloside IV (AS-IV) combined with bone marrow mesenchymal stem cells (BMSCs) on streptozotocin (STZ) induced type 1 diabetic rats. Methods: Eight male Sprague-Dawley (SD) rats aged 8 weeks were randomly selected as the normal control group, and the remaining rats were given intraperitoneal injection of STZ（60 mg/kg）to establish type 1 diabetes models. The diabetic rats were randomly divided into model group, BMSCs treatment group and BMSCs + AS-IV treatment group (n=8). BMSCs+ AS-IV group was given AS-IV solution by oral gavage. BMSCs group and BMSCs+ AS-IV group were injected with BMSCs by caudal vein. The normal control group and model group were injected with the same dose of serum-free DMEM culture medium. At the end of the 10th week, the excretion of urine albumin and renal histopathology were examined. The expressions of α-SMA, Desmin, Nephrin and NOX4 in the renal tissues were detected by immunohistochemistry. Results: Compared with diabetes model group, the renal pathological injury was significantly improved, the expression of NOX4, α-SMA and Desmin in the renal tissue was decreased, the expression of Nephrin was increased, and the excretion of urinary protein was reduced in BMSCs treatment group and BMSCs + AS-IV treatment group, and the combination treatment group was more significant. Conclusion: Treatment of AS-IV combined with BMSCs can alleviate renal pathological injury in DN rats, improve oxidative stress and reduce proteinuria excretion, has a protective effect on the kidney of STZ-induced type 1 diabetic rats. |
