摘要 目的 研究膝关节骨关节炎患者血清中TNF -α和IL - 6水平与骨关节炎的病变严重程度的关系 ,探讨TNF -α和IL - 6在骨关节炎发病中的作用及其在临床上反映OA早期病理变化的可靠性。方法 对 5 2例单侧膝关节骨性关节炎的患者及 2 1名正常人分别拍摄双侧单足站立位膝关节X线片。根据X线片将膝关节骨关节炎患者分早、中、晚 3期。正常人及患者均抽取静脉血 ,患者治疗前抽取患膝关节液。用夹心酶联免疫吸附法测定血清及关节液样本中的TNF -α和IL - 6的水平。结果 膝关节骨关节炎患者血清中TNF -α及IL - 6含量高于正常人 ,差异有显著性 (P <0 0 1)。膝关节骨关节炎患者血清中TNF -α水平在早期已明显增高 ,早期与中期水平并无统计学差异 ,而晚期水平达到最高 ;血清中IL - 6水平在早期已明显增高 ,中期达到最高 ,晚期则明显降低(P <0 0 1)。膝关节骨关节炎患者治疗前血清与关节液中TNF -α、IL - 6水平存在相关 ,相关系数rTNF -α=0 74 (P<0 0 1) ,rIL -6=0 73(P <0 0 1) ,其相关性均具有统计学意义。结论 TNF -α、IL - 6在膝关节骨关节炎患者血清与关节液中均有较高水平 ,并与骨关节炎软骨破坏严重程度相关 ;在膝关节骨关节炎的不同时期 ,分别存在着不同的高峰期。它们在患者血清与关节液中的水?
