目的 研究消瘀散新组方对膝骨关节炎(knee osteoarthritis,KOA)兔关节软骨的作用及机制。 方法 将42只6月龄普通级新西兰白兔随机分为正常组、模型组、消瘀散组、消瘀散新组方组,每组10只(另2只用于模型验证)。除正常组外,其他各组兔均按照改良Hulth法对右侧膝关节进行KOA造模。造模5周后,对消瘀散组、消瘀散新组方组动物分别给予相应的贴膏进行膝关节炎治疗,每天1次,每次持续10 h。连续给药治疗2周后,取4组兔膝关节软骨,行大体观察并采用Outerbridge分级法评价各组软骨损伤情况,采用HE染色法在光学显微镜下观察各组兔膝关节软骨、钙化层和软骨下骨病理改变,并采用Mankin's法评价软骨退变程度,采用免疫组织化学法在光学显微镜下观察各组兔膝关节软骨组织中基质金属蛋白酶13(matrix metalloproteinase- 13,MMP-13)的表达情况。 结果 关节软骨大体观察后Outerbridge评级比较发现,消瘀散组较模型组的高分级动物数减少(P<0.05),消瘀散新组方组比消瘀散组的高分级动物数也减少(P<0.05)。HE染色发现4组兔关节软骨的Mankin's评分由高到低依次为模型组(10.82±1.76)、消瘀散组(6.19±1.23)、消瘀散新组方组(2.64±1.18)和对照组(0.28±0.17),各组间差异有统计学意义(P<0.05)。免疫组织化学检测发现各组兔关节软骨组织中MMP-13表达阳性率由高到低依次为模型组(67.90±13.94)%、消瘀散组(37.10±19.16)%、消瘀散新组方组(13.60±3.10)%和对照组(3.20±2.39)%,各组间差异有统计学意义(P<0.05)。 结论 消瘀散新组方可修复KOA兔关节软骨损伤,降低软骨组织中MMP-13的表达水平,这可能是其治疗骨关节炎的作用机制之一。
