【摘要】目的 探討重癥急性胰腺炎（SAP）中IL-10及IL-18的表達(dá)及其與SAP肺損傷的關(guān)系。
方法 將48只SD大鼠按隨機(jī)數(shù)字表法均分為對(duì)照組和SAP組，動(dòng)態(tài)定量測(cè)定肺濕重系數(shù)、腹水量、血清淀粉酶、血清IL-10及IL-18的變化和半定量RT-PCR檢測(cè)肺組織中IL-10 mRNA及IL-18 mRNA的表達(dá)，并在光鏡下觀察胰腺及肺組織病理學(xué)改變。
結(jié)果 各時(shí)相SAP組肺濕重系數(shù)、腹水量、血清淀粉酶、血清IL-10及IL-18水平和肺組織中IL-10 mRNA及IL-18 mRNA的表達(dá)與對(duì)照組相比均明顯增高（P＜0.05,P＜0.01）。SAP組大鼠血清中IL-18水平和肺組織IL-18 mRNA表達(dá)水平均與肺濕重系數(shù)（r=0.68，P＜0.01； r=0.72，P＜0.01）及肺損傷病理評(píng)分（r=0.74,P＜0.01; r=0.79,P＜0.01）呈正相關(guān)，而血清中IL-10水平和肺組織IL-10 mRNA表達(dá)水平均與肺濕重系數(shù)（r=-0.62, P＜0.01; r=-0.69, P＜0.01)及肺損傷病理評(píng)分（r=-0.66,P＜0.01; r=-0.60,P＜0.01）呈負(fù)相關(guān)。
結(jié)論 IL-18參與了SAP并發(fā)肺損傷的病理過程，而IL-10對(duì)肺損傷有保護(hù)作用。
