目的建立盲腸結扎穿孔術( CLP) 誘導的ALI/ARDS 動物模型, 研究ALI/ARDS 與腎素-血管緊張素系統( RAS) 的關系, 為ALI/ARDS 的治療探索新途徑。方法在CLP 后18 h 觀察小鼠的癥狀、血氣分析、肺濕/ 干重比( W/D) 和肺組織病理等指標; 采用免疫組織化學、Western blot 和放射免疫等方法研究ALI/ARDS 動物模型中RAS 幾種關鍵酶( ACE、ACE2 和AngⅡ) 的變化規律, 應用卡托普利( ACE 拮抗劑) 、重組小鼠ACE2( rmACE2) 進行干預, 觀察干預后的變化。結果 CLP 誘導小鼠在術后18 h 出現典型的ALI/ARDS改變, 手術組較假手術組小鼠肺水含量明顯增多, PaO2 /FiO2明顯下降[ ( 194. 3 ±23. 9) mm Hg比( 346. 7 ±20. 5) mm Hg, P lt;0. 01] , 肺組織病理出現明顯的肺損傷改變。Western blot 和免疫組化結果顯示: 與假手術組比較, ALI/ARDS 小鼠肺組織的ACE2 表達下降, ACE 無明顯差異。ALI/ARDS 小鼠機體的AngⅡ水平明顯升高; 藥物干預后, 與手術組比較, 卡托普利組和rmACE2 組不同程度的抑制體內AngⅡ 的生成[ 肺: ( 1. 58 ±0. 16) fmol /mg、( 1. 65 ±0. 21) fmol /mg比( 2. 38 ±0. 41) fmol /mg; 血: ( 178. 04 ±17. 87) fmol /mL、( 153. 74 ±10. 24) fmol /mL比( 213. 38 ±25. 44) fmol /mL] 。結論 CLP誘導小鼠出現典型的ALI/ARDS 改變; ALI/ARDS 模型存在RAS 激活; ACE 對RAS 可能起正調節作用, ACE2 起負調節作用。
