目的:通过观察去卵巢大鼠关节软骨及软骨下骨的变化,探讨电针对骨保护素/核因子κB受体活化因子/核因子κB受体活化因子配体(OPG/RANK/RANKL)信号通路及基质金属蛋白酶(MMP)-13表达的影响.方法:雌性3月龄SD大鼠随机分为假手术组、模型组、电针组,每组8只.模型组及电针组均切除双侧卵巢复制模型,假手术组切除卵巢周围同等大小脂肪组织.电针组电针大鼠双侧"三阴交""阳陵泉""阴陵泉""足三里",频率3 Hz/15 Hz,强度1 mA,持续30 min,每日1次,每周5次,共12周.番红染色及Mankin's评分观察软骨全层结构;显微CT及骨组织定量分析软骨下骨变化;ELISA法检测尿液Ⅰ型胶原C端肽(CTX-Ⅰ)、Ⅱ型胶原C端肽(CTX-Ⅱ)...

OBJECTIVE: To observe the effect of electroacupuncture (EA) on histopathological changes of cartilage and subchondral bone and osteoprotegerin (OPG)，receptor activator of nuclear factor-κB (RANK), and RANK ligand (RANKL) (OPG/RANK/RANKL) signaling and the expression of matrix metalloproteinase-13 (MMP-13) in ovariectomized(OVX)rats, so as to explore its mechanism underlying improvement of osteoporosis. METHODS: Three-month female SD rats were randomly divided into sham operation, model and EA groups (n＝8 in each group). The ovoariectomy mode...
