[目的]观察盲肠结扎穿孔(Cecal ligation and puncture,CLP)所致的脓毒症诱导急性肾损伤(AKI)后大鼠不同时间点的血清及肾组织中NLRP3/ASC/caspase-1/IL-1β/IL-18的表达情况。[方法]建立大鼠CLP诱导的脓毒症AKI模型,并于手术后不同时...[目的]观察盲肠结扎穿孔(Cecal ligation and puncture,CLP)所致的脓毒症诱导急性肾损伤(AKI)后大鼠不同时间点的血清及肾组织中NLRP3/ASC/caspase-1/IL-1β/IL-18的表达情况。[方法]建立大鼠CLP诱导的脓毒症AKI模型,并于手术后不同时间点用ELISA试剂盒方法测定血清尿素氮(BUN)、血清肌酐(Scr)水平及IL-1β/IL-18的表达量;采用Western blotting法检测肾脏组织NLRP3/ASC/caspase-1/IL-1β/IL-18蛋白水平,并对肾脏组织进行HE染色病理分析。[结果]CLP诱导的脓毒症大鼠血清BUN和Scr水平显著增高,肾小管坏死也显著增加,均于CLP术后24 h达到高峰,与假手术组大鼠相比差异显著(P<0.05或P<0.01);大鼠肾脏组织中NLRP3/ASC/caspase-1/IL-1β/IL-18及血清IL-1β/IL-18水平也随着损伤程度的加重表现出升高趋势,与假手术组相比差异均达到显著水平。[结论]大鼠脓毒症AKI后肾组织或血清中NLRP3/ASC/caspase-1/IL-1β/IL-18蛋白水平表达增加,表明NLRP3炎症小体的激活可能对脓毒症AKI及其病理改变有促进作用。展开更多
