摘要 目的:研究针刺对多囊卵巢综合征(PCOS)大鼠卵巢转化生长因子β1(TGF-β1)及其mRNA表达的影响,探讨针刺促排卵的作用机制。方法:24日龄雌性大鼠颈背部皮下注射脱氢表雄酮(DHEA)制作PCOS大鼠模型,对照组同期皮下注射油剂。PCOS大鼠随机分为模型组、针刺组。模型组不作任何处理,针刺组于80日龄起进行针刺干预,每日1次,连续6周。治疗结束后各组大鼠处死,检测血清性激素水平,取卵巢称重,用免疫组化和RT-PCR方法检测TGF-β1及其mRNA表达水平。结果:与模型组相比,对照组和针刺组卵巢湿重、卵巢TGF-β1及其mRNA表达水平、血清T、E2水平均显著降低。结论:针刺能显著降低PCOS大鼠卵巢TGF-β1及其mRNA的表达,抑制TGF-β1对卵巢和激素合成的作用,改善PCOS大鼠多囊样变和高雄激素血症,促进排卵。
