1、临床麻醉学杂志2014年7月第30卷第7期JClinAnesthesiol,July2014,Vo1.3O,No.7·709·.实验研究.丙泊酚联合瑞芬太尼对肝硬化大鼠肝脏缺血一再灌注损伤的影响王建珍杨贺陈琳【摘要】目的评价丙泊酚联合瑞芬太尼对肝硬化大鼠肝脏缺血一再灌注损伤的影响。方法6o只成年健康雄性SD大鼠,随机分为假手术组(s组)、模型组(M组)、丙泊酚组(P组)、瑞芬太尼组(R组)、丙泊酚联合瑞芬太尼组(PR组)。M、P、R、PR组制备大鼠肝硬化模型,成功1周后制备肝脏缺血一再灌注损伤模型
2、,s组仅剖腹。P、R、PR组于肝脏缺血前10min经股静脉持续1h分别泵入丙泊酚2Omg·kg·h~、瑞芬太尼1btg·kg·min_。、丙泊酚20mg·kg·h和瑞芬太尼1g·kg·min_。,M组给予等容量生理盐水。于再灌注4h采静脉血样,测定血清天冬门氨酸转氨酶(AST)、丙氨酸转氨酶(ALT)活性;处死大鼠,取肝组织测定肝实质细胞Bel一2与Bax蛋白的表达,计算肝细胞凋亡指数(AI),光镜和电镜下观察肝组织的病理学变化。结果与s组比较,其余各组血清AST、ALT活性增强,肝实质细胞Bel
3、-2、Bax蛋白表达上调,AI升高(P<0.05);与M组比较,P、R、PR组血清AST、ALT活性降低,肝实质细胞Bd-2蛋白表达上调、Bax蛋白下调,AI降低(P<0.05);与P、R组比较,PR组血清AST、ALT活性降低,肝实质细胞Bcl-2蛋白表达上调、Pax蛋白表达下调,AI均降低(P4、应较两者单独应用时增强。【关键词】肝硬化;缺血一再灌注损伤;细胞凋亡;丙泊酚Effectsofpropofolcombinedwjthremifentanilonhepaticischemia-reperfusioninjuryincirrhoticratsWANGJian-zhen,YANGHe,CHENLin.DepartmentofAnesthesiology,AffiliatedHospitalofNingxiaMedicalUniversity,Yinchuan750004,ChinaC5、orrespondingauthor:WANGJian-zhen,Emaif:wangjz6567@126.com[Abstract]ObjectiveToinvestigatetheeffectsofpropofolcombinedwithremifentanilonhe—paticischemia-reperfusioninjuryincirrhoticrats.MethodsSixtymaleSDratsof260to300gramswererandomlydividedintofivegr6、oups(n=12):thesham-operatedgroup(groupS);themodelcon—trolgroup(groupM);propofolgroup(groupP);remifentanilgroup(groupR);propofolcombinedwithremifentanilgroup(groupPR).IngroupM,P,R,PR,thehepaticarteriesandveinsofmiddleand1eft1obeswereoccludedfor20minaft7、er1whepatocirrhosisbyusingfourprincipalfactors,andgroupSwentthroughanopensurgeryonly.IngroupsP,R,andPR,porpofol(atarate20mg·kg一·h一for1h)、remifentanil(atarate1g·kg一·min一for1h)andporpofol(atarate20mg·kg一·h一)combinedwithremifentanil(atarate1“g·kg一·min一fo8、r1h)wasinfusedivat10minbeforeis—chemia,respectively.IngroupM,normalsalinewasinfusedivatthesamerate.B1oodsamplesweretakenattheendof4hreperfusiontodetermineserumAST。ALTactivity.MeanwhileliverspecimenswerecollectedtoassessBcl-2andBaxproteinexpres
