【摘要】：目的評價前列腺素E1(PGE1)對心臟瓣膜置換術(shù)患者心肌細胞核轉(zhuǎn)錄因子κB(NF-κB)活性和血漿腫瘤壞死因子α(TNF-α)水平的影響。方法擇期行體外循環(huán)下心臟瓣膜置換術(shù)的患者40例,年齡32~67歲,體質(zhì)量指數(shù)17~28kg/m2,美國麻醉師協(xié)會(ASA)分級Ⅱ或Ⅲ級,紐約心臟病協(xié)會(NYHA)分級Ⅱ或Ⅲ級。采用隨機數(shù)字表法,將患者分為2組(n=20):對照組(C組)和PGE1組(P組)。麻醉誘導(dǎo)后P組靜脈輸注PGE1 20ng·kg-1·min-1,至手術(shù)結(jié)束,C組給予等容量生理鹽水。于體外循環(huán)前(T0,基礎(chǔ)值)、體外循環(huán)開始后30min(T1)、體外循環(huán)結(jié)束時(T2)、體外循環(huán)結(jié)束后12h(T3)、體外循環(huán)結(jié)束后24h(T4)抽取動脈血,檢測血漿TNF-α水平;于T0和T2時取右心耳組織,觀察組織病理學(xué)變化,并用蛋白免疫印跡法(Western blot)檢測NF-κB活性。結(jié)果與C組比較,P組T1~T4時血漿TNF-α水平下降(P0.05),T2時心肌病理學(xué)損傷明顯減輕,心肌細胞NF-κB活性下降(P0.05)。結(jié)論 PGE1可減輕心臟瓣膜置換術(shù)患者心肌損傷,其機制與抑制心肌細胞NF-κB活性,減少血漿TNF-α水平有關(guān)。
