目的觀察急性胰腺炎發(fā)生時肝組織中核因子κB（NFκB）對TNFα mRNA表達的調(diào)節(jié)及其在肝損傷中的作用。方法Wistar大鼠72只，隨機均分為急性胰腺炎組（AP組）、急性胰腺炎吡咯基二硫氨基甲酸酯（PDTC）處理組（APP組）以及對照組（SO組）。分別在術(shù)后3 h、6 h、12 h及24 h檢測肝組織NFκB活性、TNFα mRNA的表達以及血漿ALT水平。結(jié)果AP組及APP組的NFκB活性、TNFα mRNA表達及血漿ALT水平分別在術(shù)后3～6 h及3～24 h顯著高于SO組。在應(yīng)用了NFκB抑制劑的APP組，NFκB活性、TNFα mRNA表達以及血漿ALT水平均顯著低于AP組。結(jié)論急性胰腺炎發(fā)生時，肝臟中活化的NFκB促進了TNFα mRNA的表達，并參與了肝損傷的發(fā)生。
