摘要 目的:探讨Dkk-1干预对兔膝骨关节炎软骨细胞修复的影响。方法取2周龄新西兰大耳兔60只,随机分为空白对照组、模型组和DKK-1组各20只,空白对照组、模型组关节腔内均注射生理盐水,DKK-1组关节腔内注射纯化DKK-1,1个月后取各组兔子膝关节软骨细胞进行检测,观标本24h后行甲苯胺蓝化学染色的相关指标变化。结果三组软骨大体形态按 Mankin's评分比较,有显著性差异(P<0.01),三组HE染色病理学观察按Mankin's评分空白对照组与模型组、模型组与DKK-1组间比较,差异均有显著意义(P<0.01)。结论 DKK-1干预可使兔子的软骨细胞得到部分修复、凋亡及坏死减少,骨性关节炎的到控制并好转,对骨性关节炎有积极的治疗作用。
