目的探討轉化生長因子(TGF)-α和TGF-β1在90%極限門靜脈分支結扎大鼠肝臟組織中的表達及其與肝臟再生的關系。
方法 SD雄性大鼠96只，隨機平均分成假手術組和門靜脈結扎（PBL）組,觀察術后0.5、1、3、5、7、14、21和28 d總肝臟和未結扎側肝臟質量變化，光學顯微鏡下觀察未結扎側肝細胞的形態變化，用免疫組化方法檢測未結扎側肝細胞的增殖細胞核抗原（PCNA）及TGF-α和TGF-β1的表達。
結果 90%極限門靜脈分支結扎后，結扎側肝葉呈進行性萎縮、變小，未結扎側肝葉占總肝質量的比例在術后1 d 內增加較緩慢，而在術后1～5 d增加速度明顯加快，5 d以后增加變慢，于7 d達“平臺期”。與假手術組比較,PBL組術后肝組織中PCNA表達在術后0.5～3 d明顯增多(P lt;0.01)，術后5 d達高峰，7 d有所減少，但仍高于假手術組(P lt;0.01)，以后減少接近假手術組。假手術組術后肝臟可見少量TGF-α和TGF-β1表達，PBL組大鼠未結扎側肝葉術后0.5 d開始兩者表達量增加,分別至術后3 d和1 d達高峰(P lt;0.05),術后7～28 d下降并接近假手術組(P gt;0.05)。
結論大鼠90%PBL術后導致未結扎側肝臟再生，而TGF-α和TGF-β1蛋白表達與肝臟再生啟動和增殖過程密切相關。
