目的　研究環氧合酶-2(COX-2)在重癥急性胰腺炎(SAP)大鼠肝組織中的表達,探討COX-2在SAP肝臟損傷中的作用。
方法　以3.5%牛磺膽酸鈉胰膽管逆行注射誘導大鼠SAP模型。隨機分為對照組和SAP組，術后4、8、16及24 h測定血清淀粉酶(AMY)、丙氨酸氨基轉移酶(ALT)、天冬氨酸氨基轉移酶(AST)、腫瘤壞死因子(TNF)-α水平和腹水AMY; 光鏡下觀察胰腺和肝組織損傷情況; 免疫組化方法檢測COX-2在肝組織中的表達。
結果　SAP組各時間點血清AMY、ALT、AST、TNF-α及腹水AMY水平均較對照組明顯升高,差異均有統計學意義(P lt;0.05),與胰腺和肝臟組織的病理學改變相一致。術后不同時相COX-2在肝組織中的表達陽性率明顯高于對照組,差異均有統計學意義(P lt;0.05),COX-2表達與ALT(rs=0.949,P=0.039)、AST(rs=0.972,P=0.016)及血清AMY(rs=0.944,P=0.041)呈正相關。
結論　SAP時COX-2表達上調可能在SAP合并肝臟損傷中發揮重要作用。
