目的探討肝細胞生長因子(HGF)對大鼠移植小腸粘膜結構的保護作用。方法近交系Wistar (RT1k)大鼠行異位全小腸移植后第2天開始給予腸外營養至第10天，對照組(n=10)行常規TPN支持，HGF組(n=10)行常規TPN支持的同時加用人胎肝細胞生長因子150 μg/（kg·d），觀察移植腸粘膜結構的形態學參數如絨毛高度、絨毛寬度、隱窩深度、粘膜厚度及絨毛表面積的變化，以及移植腸上皮細胞超微結構變化及移植腸粘膜蛋白質和DNA含量的改變。結果移植前兩組腸粘膜形態學參數差異無顯著性意義，行移植及TPN后對照組各參數較移植前明顯減小(P＜0.05）；而HGF組各參數與移植前比較變化不明顯（P＞0.05），但明顯高于對照組，分別是絨毛高度為(298.79±22.31) μm vs (176.45±14.62) μm,P=0.001；絨毛寬度為(107.46±12.34) μm vs (74.20±16.85) μm,P=0.004；隱窩深度為(104.56±11.17) μm vs (74.45±8.34) μm,P=0.000 5；粘膜厚度為(409.53±35.83) μm vs (259.38±24.65) μm,P=0.003；絨毛表面積為(0.101±0.011) mm2 vs (0.041±0.005) mm2,P=0.001。HGF組蛋白質含量明顯高于對照組(P=0.012)而與基準值接近，分別為（89.65±9.28） mg/g濕重、(53.73±11.45) mg/g濕重和(92.64±10.52) mg/g濕重，DNA含量也顯著高于對照組〔(0.89±0.09) mg/g濕重vs (0.51±0.06) mg/g濕重,P=0.008〕。HGF組移植腸上皮細胞超微結構基本保持完好，而對照組則出現明顯線粒體腫脹，嵴短小紊亂和微絨毛萎縮。結論肝細胞生長因子能較好地保護大鼠移植小腸粘膜結構，維持移植腸上皮細胞超微結構的完整。
