目的 研究p38絲裂原活化蛋白激酶(p38 mitogen-activated protein kinase,p38MAPK)在重癥急性胰腺炎(severe acute pancreatitis,SAP)大鼠肺組織中的表達(dá)情況,并初步探討p38MAPK與SAP肺毛細(xì)血管內(nèi)皮屏障損傷的關(guān)系。
方法 將40只健康雄性SD大鼠隨機(jī)(隨機(jī)數(shù)字表法)分為假手術(shù)(SO)組和SAP組,SAP組又再分為3、6、12及24h4個(gè)時(shí)間點(diǎn)組,共5組,每組8只。采用胰膽管逆行注射5%?;悄懰徕c的方法建立SAP大鼠模型。采用HE染色方法觀察大鼠肺和胰腺組織的病理學(xué)改變; 采用ELISA法檢測(cè)血清腫瘤壞死因子-α(TNF-α)和白細(xì)胞介素-1β(IL-1β)水平; 采用免疫組化染色方法檢測(cè)肺組織中磷酸化p38(p-p38)蛋白和水通道蛋白1(AQP1)的表達(dá)水平; 采用實(shí)時(shí)定量熒光PCR法(real-time PCR)檢測(cè)肺組織中AQP1 mRNA的表達(dá)水平。
結(jié)果 SAP各時(shí)間點(diǎn)組大鼠肺組織充血水腫,炎癥細(xì)胞浸潤;胰腺組織可見大片壞死,部分腺葉結(jié)構(gòu)模糊甚至消失;血清TNF-α和IL-1β水平均較SO組高(P<0.05)。SO組大鼠肺組織中p-p38蛋白僅有微量表達(dá),而在SAP 3h組,p-p38蛋白的表達(dá)就明顯上調(diào),在6 h時(shí)達(dá)高峰,24h時(shí)仍高于SO組(P<0.05)。SAP各時(shí)間點(diǎn)組大鼠肺組織中AQP1 mRNA及其蛋白的表達(dá)水平均較SO組下降(P<0.05),并隨著時(shí)間的推移而逐漸下降; SAP組大鼠AQP1 mRNA的表達(dá)與TNF-α、IL-1β及p-p38蛋白之間均存在負(fù)相關(guān)關(guān)系(r=-0.87,P<0.05;r=-0.88,P<0.05;r=-0.78,P<0.05)。
結(jié)論 肺組織中AQP1蛋白表達(dá)的下調(diào)是SAP肺毛細(xì)血管內(nèi)皮屏障損傷的重要原因之一,其可能與p38MAPK的激活及炎癥因子的過度釋放有關(guān)。
