摘要 目的观察复元胶囊对实验性骨关节炎软骨中基质金属蛋白酶13、组织型金属蛋白酶抑制剂1,2及病理形态方面的影响。方法选用新西兰兔66只,随机分为:正常对照组6只,不给予任何处理;模型对照组12只,造模后生理盐水灌胃;四环素组、复元胶囊低、中、高剂量组各12只,造模后分别用四环素、复元胶囊灌胃。连续灌胃4~12w后,比较各组关节软骨病理变化;免疫组化法检测兔膝关节软骨中MMP13、TIMP2蛋白质水平的变化;RT-PCR法检测关节软骨中MMP13、TIMP1及TIMP2mRNA表达。结果实验组软骨Mankin′s评分都显著低于模型对照组,实验组MMP13的mRNA表达水平明显低于模型对照组,而其TIMP1、TIMP2的mRNA的水平较模型对照组有所增加。MMP13主要表达于软骨表层及中上层,实验组MMP13表达量低于模型对照组(P〈0.05)。结论复元胶囊能明显抑制骨关节炎软骨中MMP13的蛋白和mRNA的水平,能提高OA软骨中TIMP1,2的蛋白和mRNA的水平,稳定二者水平,对软骨退变有一定的防治作用。
