目的  觀察δ阿片受體激動(dòng)劑D-丙2,D-亮5腦啡肽(D-Ala2,D-Leu5-enkephali,DADLE)對(duì)膿毒癥大鼠肝細(xì)胞凋亡及肝組織bcl-2和caspase-3表達(dá)的影響,探討DADLE對(duì)肝臟保護(hù)作用的可能機(jī)理。
方法  采用盲腸結(jié)扎加穿孔(CLP)法制作大鼠膿毒癥模型,SD大鼠54只(雌雄不限),采用隨機(jī)數(shù)字表法隨機(jī)分為CLP組(n=18)、DADLE組(n=18)和假手術(shù)組(n=18)。在不同時(shí)間點(diǎn)(2、4及6 h)處死大鼠,原位末端標(biāo)記法檢測(cè)肝細(xì)胞凋亡情況,免疫組化法檢測(cè)肝組織中bcl-2及caspase-3蛋白表達(dá)的動(dòng)態(tài)變化并觀察肝臟的病理改變。
結(jié)果  CLP組大鼠肝組織病理損害明顯較假手術(shù)組嚴(yán)重,DADLE組肝臟的病理變化明顯改善; CLP組大鼠肝組織細(xì)胞凋亡指數(shù)明顯較假手術(shù)組升高(P<0.01),以4 h最顯著(P<0.01),DADLE 組各時(shí)相肝細(xì)胞凋亡指數(shù)均明顯降低(P<0.01); CLP組大鼠肝組織caspase3蛋白的表達(dá)強(qiáng)度比假手術(shù)組明顯增強(qiáng)(P<0.01),而bcl-2蛋白的表達(dá)則明顯減弱(P<0.05); DADLE組肝組織caspase-3蛋白的表達(dá)強(qiáng)度較CLP組明顯減弱(P<0.01),而bcl-2蛋白的表達(dá)則明顯增強(qiáng)(P<0.05)。肝組織caspase-3的表達(dá)與肝細(xì)胞凋亡指數(shù)呈正相關(guān)(r=0.83,P<0.01),bcl-2的表達(dá)與肝細(xì)胞凋亡指數(shù)呈負(fù)相關(guān)(r=-0.65,P<0.01)。
結(jié)論  DADLE能明顯改善膿毒癥大鼠肝臟的病理變化,其作用機(jī)理可能與DADLE下調(diào)caspase-3表達(dá)、上調(diào)bcl-2表達(dá),從而抑制肝細(xì)胞凋亡有關(guān)。
