2、NF—B活性的变化。结果限制性液体复苏组大鼠的存活时间较快速大量液体复苏组及无液体复苏组明显延长(尸均<0.05);限制性液体复苏组大鼠72h存活率明显高于快速大量液体复苏组和无液体复苏组,但低于对照组(P均3、亡率;PBMC中NF—B活性与预后密切相关,NF—B活性高则提示预后不良,而限制性液体复苏时NF一B活性明显降低,有助于改善预后。【关键词】休克,失血性;液体复苏外周血单个核细胞;核转录因子一BEffectsofdifferentmeansoffluidresuscitationontheactivityofnuclearfactor—KBinperipheralbloodmononuclearcellsinratswithhemorrhagicshockZHA0Zhong一iang,SUNJi—wu,DENGZhe.DepartmentofEmergency,ShenzhenSecond4、PeoplesHospital,ShenzhenEmergencyCenter,Shenzhen518035,Guangdong,China[Abstract]ObjectiveToobservetheeffectsofdifferentmeansoffluidresuscitationontheactivityofnuclearfactor—KB(NF—KB)inperipheralbloodmononuclearcells(PBMC)inratswithhemorrhagicshock.MethodsRatmodelsofhemorrhagicshockwerereproducedus5、ingthemodifiedCaponemethod.Thirty—twoSDratswererandomlydividedintofourgroups:controlgroup,nofluidresuscitationgroup,limitedfluidresuscitationgroup,largequantityfluidrapidresuscitationgroup(eachn=8).Thesurvivaltimeandsurvivalrateofeachgroupwerecompared.TheactivitiesofNF—KBinPBMCwereassessedwithenzy6、me—linkedimmunosorbentassay(ELISA).ResultsThesurvivaltimeoflimitedfluidresuscitationgroupwaslongerthanthatoflargequantityfluidrapidresuscitationgroupandthatofnofluidresuscitationgroup(bothP7、itationgroupandalsoinnofluidresuscitationgroup,whilelowerthanthatofcontrolgroup(allP
