目的 研究高遷移率族蛋白B1 (high mobility group box-1 protein,HMGB1) mRNA表達對急性壞死性胰腺炎(acute necrotizing pancreatitis,ANP)大鼠腸黏膜緊密連接蛋白-1 (zonula occludens protein-1,ZO-1)表達的影響,初步探討ANP時腸黏膜屏障損傷的可能機理。
方法 將96只Wistar大鼠隨機(隨機數字表法)均分為ANP組、丙酮酸乙酯(EP)組及假手術組,3組均分別于術后6、12、24及48h時各抽取8只大鼠,取腹主動脈血和回腸組織。采用全自動生化分析儀檢測血淀粉酶(AMY)水平,采用改良酶學分光光度法檢測血漿D-乳酸水平,采用硫代巴比妥酸(TAB)比色法檢測回腸組織丙二醛(MDA)含量,采用HE染色法觀察大鼠回腸組織的病理學改變,采用免疫組織化學法(SP法)觀察回腸組織ZO-1蛋白的表達,采用逆轉錄聚合酶鏈反應(RT-PCR)法檢測回腸組織HMGB1和ZO-1mRNA的表達。
結果 各時相EP組大鼠的血AMY、D-乳酸和回腸組織MDA含量均低于ANP組(P<0.05)。6h時,ANP組大鼠回腸組織HMGB1mRNA的表達即上調,但ZO-1mRNA的表達下調;各時相EP組大鼠回腸組織HMGB1mRNA的表達水平均低于ANP組,但ZO-1mRNA的表達水平均高于ANP組(P<0.05)。各時相EP組大鼠回腸組織的病理學損傷均較ANP組明顯減輕。
結論 ANP大鼠回腸黏膜組織中ZO-1表達下調是ANP大鼠腸黏膜屏障損傷的重要原因之一,可能與炎癥介質HMGB1的過度表達有關。
