摘要 目的:探讨宣白承气汤对脓毒症大鼠保护作用的细胞信号转导机制。方法:SD大鼠30只,随机分为3组,模型组、假手术组和治疗组各10只。实验期间大鼠禁食不禁水。模型组和治疗组采用盲肠结扎穿刺法,假手术组仅翻动盲肠,不做穿刺结扎处理。治疗组在CLP后8h、12h和24h时宣白承气汤剂按1ml/100g体质量灌胃。第48h时(即实验结束时)心脏取血3ml离心后去上清液测定TNFα、IL-6含量。并取距小肠回盲部上端15cm处的肠管2cm,称重后按每1g湿重加入4℃的PBS10ml比例,冰浴匀浆约1min后,4℃放置4500转/min离心30min后取上清备用。免疫印迹法检测小肠组织中p-p38、total-p38丝裂原活化蛋白激酶表达水平。结果:模型组的TNFα及IL-6浓度与假手术组比较,均明显升高(P<0.05);与模型组比较,治疗组可明显降低血清中TNFα及IL-6浓度(P<0.05)。模型组p-p38/p-38灰度比值为0.48±0.09,假手术组的灰度比为0.16±0.03,治疗组的灰度比为0.21±0.05。与假手术组比较,模型组灰度比值明显增加(P<0.05);与模型组比较,治疗组的灰度比值明显降低(P<0.05)。结论:宣白承气汤保护肠源性脓毒症大鼠的作用机制与抑制小肠组织中p38丝裂原活化蛋白激酶信号通路有关,进而减少炎症介质TNFα、IL-6释放。
