摘要：

目的:检测TNBS诱导实验性结肠炎大鼠在穴位埋线治疗前后的NF-κBp65和STAT6mRNA的表达水平,初步阐明穴位埋线治疗实验性结肠炎大鼠的作用机理。方法:18只雄性大鼠随机分为正常组、模型组、穴位埋线组,每组6只。除正常对照组未行造模外,其余2组大鼠均采用TNBS造模。模型组不设干预,正常饮食;穴位埋线组进行穴位埋线治疗。治疗15d后观察大鼠的结肠病理组织学改变,用western blot法检测大鼠脾淋巴细胞NF-κBp65蛋白的表达;用RT-PCR法检测大鼠结肠组织STAT6mRNA的表达。结果:穴位埋线组的大鼠腹泻、黏液脓血便症状得到较快改善,大鼠黏膜组织损伤也明显改善。与正常组相比,模型组大鼠NF-κBp65和STAT6mRNA增多(P<0.01);与模型组比较,穴位埋线组NF-κBp65和STAT6mRNA减少(P<0.01)。结论:穴位埋线能通过NF-κB和STAT6双信号途径下调炎症因子,从而发挥治疗作用。
