摘要 目的:研究血清雌二醇(Estradiol,E2)水平对绝经后骨性关节炎大鼠软骨代谢的影响。方法:将20只健康雌性SD大鼠按体重均衡原则随机分成2组:对照组10只、模型组10只,模型组予以切除双侧卵巢、切断右膝交叉韧带制造绝经后骨性关节炎模型,对照组仅予以模拟切口处理。6周后,取大鼠右侧膝关节股骨髁部的软骨行病理检查,采集大鼠血清检测E2、Ⅱ型胶原羧基端端肽(C-telopeptide typeⅡcollagen,CTX-Ⅱ)的水平。结果:模型组与对照组对比软骨退变明显,股骨髁软骨Mankin评分高于对照组(P<0.05);模型组血清E2水平明显偏低(P<0.01),血清CTX-Ⅱ水平明显偏高(P<0.01)。结论:雌激素水平下降与大鼠绝经后骨性关节炎发病关系密切,血清CTX-Ⅱ水平增高能够反映大鼠骨性关节炎软骨降解情况。
