1、胃泌素释放肽受体拮抗剂RC―3095通过抑制TLR4途径减轻小鼠肝缺血再灌注损伤的研究RC-3095干预组(RC-3095),HE染色观察小鼠肝组织坏死程度,检测各组小鼠外周血谷草转氨酶(AST)、谷丙转氨酶(ALT)水平,ELISA法检测小鼠外周血及肝脏组织中细胞因子TNF-α、IL-6、IL-1β的表达水平,RT-PCR法检测肝脏组织TLR4水平。结果小鼠肝脏缺血再灌注损伤GRP及GRPR表达增加,6h达到高峰,随后表达降低;RC-3095能明显减轻肝缺血再灌注损伤模型小鼠肝脏坏死程度,抑制炎症因子(TNF-α、IL-6、IL-1β)的释放,抑制TLR4的表达。结论RC-3095可以
2、通过抑制炎症因子的释放起到保护肝缺血再灌注损伤,其可能的机制是抑制TLR4的表达。中国6/vie [关键词]胃泌素释放肽受体;RC-3095;肝缺血再灌注损伤;TLR4 [中图分类号]R657.3[文献标识码]B[]1673-9701(2017)04-0037-04 Studyontheeffectofgastrin-releasingpeptidereceptorantagonistRC-3095onreducinghepaticischemiareperfusioninjuryinmicebyinhibitingTLR4pathentofAnesthesiology,No.11
