摘要(Abstract)：

目的观察半夏泻心汤对重症急性胰腺炎(SAP)大鼠肠道损伤的保护作用及肠组织p38MAPK/核转录因子-κB(NF-κB)表达的影响并探讨其机制。方法将雄性8周龄SD大鼠30只均分为假手术组、模型组和半夏泻心汤组,用牛磺胆酸钠建立SAP模型,造模2 h后半夏泻心汤组以5 g/kg进行灌胃。24 h后检测血清中血清淀粉酶(AMY)、白细胞介素-6(IL-6)、白细胞介素-1β(IL-1β)和肿瘤坏死因子-α(TNF-α)含量,观察大鼠胰腺和回肠的病理改变,检测p38MAPK、p-p38MAPK及NF-κB在回肠组织中的表达情况。结果实验结束时模型组和半夏泻心汤组分别死了3只和1只大鼠;与假手术组比较,模型组和半夏泻心汤组AMY、IL-6、IL-1β和TNF-α含量增高;与模型组比较,半夏泻心汤组AMY、IL-6、IL-1β和TNF-α含量降低;假手术组胰腺和回肠未见病理损害,模型组胰腺组织出现明显水肿、出血、脂肪组织坏死及炎细胞浸润,回肠组织绒毛上皮脱落,仅有固有膜,同时伴有水肿炎细胞浸润,胰腺和回肠病理评分较假手术组增加;给予半夏泻心汤治疗后,胰腺和回肠的病理损伤较模型组明显减轻,病理学评分也降低;模型组p38MAPK、p-p38MAPK及NF-κB表达均较假手术组增加;半夏泻心汤组p38MAPK、p-p38MAPK及NF-κB表达较模型组减少,但较假手术组增加(均P <0.05)。结论半夏泻心汤通过减少p38MAPK/NF-κB表达从而发挥SAP大鼠肠道保护作用。
