健脾补肾方促进BMSCs增殖治疗溃疡性结肠炎的实验研究

Study of Jianpi-Bushen Fang on Treatment of Ulcerative Colitis by Promoting BMSCs Proliferation

  • 摘要: 目的 观察健脾补肾方促进骨髓间充质干细胞(Bone mesenchymal stem cells,BMSCs)增殖、分化治疗溃疡性结肠炎(Ulcerative colitis,UC)模型大鼠的可能作用机制。方法 SD大鼠随机分为空白组、模型组、BMSCs组、干预BMSCs组和联合组。采用TNBS法建立大鼠UC模型,干预BMSCs和联合组大鼠分别尾静脉注射体外中药干预的BMSCs(0.78 mg/L,1×106),联合组再予健脾补肾方(浓度13.6 g/kg)灌胃10 d,BMSCs组大鼠尾静脉注射1 mL BMSCs(1×106),空白组、模型组大鼠尾静脉分别注射1 mL生理盐水。干预第10天每组各处死5只大鼠,留取标本,Western blot法检测大鼠结肠组织肠干细胞标记物Lgr5和Ephrin-B3的蛋白表达水平,检测E-cadherin的蛋白表达水平,采用ELISA法检测各组大鼠结肠组织IL-6、IL-17和TGF-β水平。结果 各移植治疗组较模型组,Lgr5和Ephrin-B3蛋白水平升高(P<0.05),联合组Lgr5和Ephrin-B3蛋白表达较BMSCs组,差异有统计学意义(P<0.05);各治疗组E-cadherin蛋白表达较模型组均升高,其中联合组和干预BMSCs组较模型组,差异有统计学意义(P<0.05),联合组较BMSCs组,差异有统计学意义(P<0.05);联合组和干预BMSCs组IL-6、IL-17水平明显降低(P<0.05),TGF-β水平升高(P<0.05),且联合组在改善IL-6、TGF-β水平方面较单纯BMSCs治疗有统计学意义(P<0.05)。结论 健脾补肾方能够促进静脉移植的BMSCs向肠干细胞增殖分化,并调节免疫功能、修复肠黏膜,这可能是其治疗UC的可能机制之一。
