摘要 目的:研究洛伐他汀对兔关节炎关节软骨基质的保护作用。方法:以30只6个月龄新西兰大白兔行右膝关节前交叉韧带切断术。手术后将动物随机分为实验组和对照组,实验组术后立即给予关节腔内注射0.5mg/mL洛伐他汀0.2mL/kg,每周1次,连续6周;对照组则关节腔内注射等容量的生理盐水。术后6周处死动物,在解剖镜下观察股骨内髁关节软骨的大体形态学改变并评分,同时采用反转录-聚合酶链式反应检测关节软骨Ⅱ型胶原、蛋白聚糖和基质金属蛋白酶13(matrix metalloproteinase-13,MMP-13)mRNA的表达。结果:解剖镜下实验组软骨退变程度较对照组明显减轻;实验组MMP-13的表达较对照组明显减少,实验组Ⅱ型胶原和蛋白聚糖的表达较对照组明显增强。结论:在骨关节炎早期关节腔内注射洛伐他汀能够保护关节软骨基质,减轻关节软骨结构及功能的破坏。
