2、4h;D組加入終濃度為3mg/L順鉑孵育4h;Ds組加入終濃度為3mg/L順鉑,并用2.5%七氟醚孵育4h;R組采用射線2Gy輻照4h;RS組采用射線2Gv輻照,并用2.5%七氟醚孵育4h。每組細(xì)胞處理完畢后,繼續(xù)培養(yǎng)24h,檢測克隆形成情況,計(jì)算克隆形成率;采用平板克隆法和MTT法檢測細(xì)胞增殖情況,計(jì)算增殖抑制率;采用流式細(xì)胞儀檢測細(xì)胞凋亡率;采用Westernblot法檢測x連鎖凋亡抑制蛋白(XIAP)和caspase一3的表達(dá)水平。結(jié)果與c組比較,s組、D組、Ds組、R組和Rs組細(xì)胞克隆形成率降低,增殖抑制率和凋亡率升高,XIAP表達(dá)
3、下調(diào),caspase一3表達(dá)上調(diào)(P<0.05);與s組和D組比較,Ds組細(xì)胞克隆形成降低,增殖抑制率和凋亡率升高,XIAP表達(dá)下調(diào),easpase一3表達(dá)上調(diào)(P<0.05);與s組和R組比較,Rs組細(xì)胞克隆形成降低,增殖抑制率和凋亡率升高,XIAP表達(dá)下調(diào),caspase.3表達(dá)上調(diào)(P<0.05)。結(jié)論七氟醚可增強(qiáng)順鉑和7射線抑制人肺腺癌A549細(xì)胞生長的作用,其機(jī)制可能與下調(diào)XIAP表達(dá),上調(diào)caspasc一3表達(dá)有關(guān)?!娟P(guān)鍵詞】麻醉藥,吸人;順鉑;7射線;肺腫瘤Efectsofsevofluraneoninhibitionofgr
