目的:观察清热除湿通络法对大鼠痛风性关节炎模型中NALP3、Caspase-1、Pycard m RNA及NALP3、Caspase-1蛋白表达的影响。方法:将经典痛风性关节炎模型大鼠造模后采用随机数表法分为空白组、模型组、虎杖组及其各拆方组、吲哚美辛组和秋...目的:观察清热除湿通络法对大鼠痛风性关节炎模型中NALP3、Caspase-1、Pycard m RNA及NALP3、Caspase-1蛋白表达的影响。方法:将经典痛风性关节炎模型大鼠造模后采用随机数表法分为空白组、模型组、虎杖组及其各拆方组、吲哚美辛组和秋水仙碱组。造模12h后取材,随后运用RT-PCR技术检测大鼠气囊灌洗液中NALP3、Caspase-1、Pycard m RNA变化;Western blot法检测大鼠气囊灌洗液中NALP3、Caspase-1蛋白的变化。结果:以模型组为对照,虎杖组NALP3 m RNA相对表达下调,而其余组均上调;虎杖组Caspase-1 m RNA上调幅度小于其余组(除清热方组);虎杖组Pycard m RNA表达上调幅度低于其余组。虎杖组NALP3蛋白表达水平较模型组及其各拆方组、秋水仙碱组低(P<0.01,P<0.05);虎杖组Caspase-1蛋白表达量低于除湿方组、模型组(P<0.05,P<0.01)。结论:清热除湿通络法通过在蛋白质翻译层面下调NALP3、Caspase-1蛋白,干扰了NALP3炎性复合体的装配或激活,进而发挥了拮抗痛风炎性反应的作用。展开更多
