摘要 目的 :探讨针灸早期干预对原发性骨质疏松模型大鼠骨代谢的影响及其可能机理。方法 :用去卵巢方法建立大鼠骨质疏松模型。 2 4只 SD大鼠随机分为针刺组、模型组、假手术组。针刺组于造模后第 1 1天开始治疗 ,观察骨代谢相关的生理、病理及生化指标。结果 :经过 3个疗程的电针为主治疗 ,针刺组没有出现去势大鼠所特有的体重代偿性增加 ,子宫系数高于模型组 ,白介素 1β (IL -1β)含量明显低于假手术组与模型组 ,离体股骨密度高于模型组 ,尿脱氧吡啶啉 (DPD) /肌酐 (Cr)比值明显低于模型组 ,均 P<0 .0 5。腰椎扫描电镜显示 ,模型组骨小梁稀疏、断裂 ;针刺组骨小梁连接成网状 ,排列整齐 ;但与假手术组比较 ,骨小梁密度减小 ,间隙增大。结论 :电针可以明显延缓去势大鼠的骨质疏松进程 ,其机理可能是通过抑制 IL-1 β,减少由其介导的基质细胞和成骨细胞分泌的多种细胞因子 ,抑制骨吸收。
