摘要
目的观察中药健脾利湿养肝方对慢加急性肝衰竭(ACLF)模型大鼠嘌呤能离子通道型受体7(P2X7R)的影响,探讨健脾养肝利湿方治疗ACLF的作用机制。方法利用免疫法建立ACLF模型,随机分为模型组和实验组,模型组给予生理盐水灌胃,实验组给予健脾利湿养肝方灌胃,治疗1周。10%水合氯醛麻醉腹主动脉取血处死,留取肝脏标本行HE、免疫组化、Western blot、RT-PCR检测。结果实验组较对照组可以降低ACLF模型大鼠谷丙转氨酶(ALT)、谷草转氨酶(AST)、凝血酶原时间(PT)、国际标准比值(INR),提高凝血酶原活动度(PTA),差异具有统计学意义(<0.05);Western blot结果显示,实验组较对照P2X7R蛋白在肝内的表达降低,差异具有统计学意义(<0.05);RT-PCR显示,实验组较对照组P2X7R基因表达降低,差异具有统计学意义(<0.05)。结论中药健脾利湿养肝方可以降低ACLF模型大鼠P2X7R的表达。
