摘要 目的探讨双氯芬酸钠对大鼠胶原诱导关节炎的影响。方法采用Ⅱ型胶原诱导大鼠关节炎模型,造模成功后随机分为3组,治疗21d。观察治疗前后大鼠的关节肿胀指数、外周血IL-β及TNF-a、PGE2的变化及关节滑膜HE染色。结果关节肿胀指数比较:治疗前3组差异无统计学意义(P>0.05),治疗后,双氯芬酸钠组、甲氨蝶呤组分别与生理盐水组比较差异有的统计学意义(P<0.05)。双氯芬酸钠组、甲氨蝶呤组和生理盐水组比较,血清中TNF-a、PGE2差异有统计学意义(P<0.05),双氯芬酸钠组和甲氨蝶呤组差异无统计学意义(P>0.05)。3组血清IL-β浓度差异无统计学意义(P>0.05)。结论双氯芬酸钠可下调大鼠胶原型关节炎血清TNF-a、PGE2,对关节病理有改善。
