摘要
目的 :在建立异位双造口小肠移植 (SBT)后淋巴管重建模型的基础上 ,研究淋巴管重建 (LR)、早期肠内营养对受者血浆游离脂肪酸 (FFAs)的影响。 方法 :用气相色谱法测定大鼠小肠移植术前和术后 1、4、7、10和 14天血浆中游离脂肪酸C14 、C16、C18∶1、C18∶2 、C2 0∶4浓度。 结果 :在小肠移植后立即行淋巴管重建的大鼠 ,术后血浆游离脂肪酸浓度较未行淋巴管重建者高 ,特别是在术后早期 (7天内 )更显著。 结论 :小肠移植后立即行淋巴管重建、早期肠内营养不仅可为机体提供充分的能量 ,而且能有效地纠正低血浆游离脂肪酸 ,尤其可有效地防止小肠移植后早期必需脂肪酸的缺乏 ,发挥游离脂肪酸如花生四烯酸C2 0∶4及其衍生物PGE2 ,TXA2 和LTB4等在免疫细胞功能调节中的重要作用。
Objectives: To investigate the effects of immediate reconstruction of lymphatic drainage of the graft after small bowel transplantation (SBT) and early enteral nutrition (EN) support on plasma level of free fatty acids (FFAs) using a model of lymphatic reconstruction (LR) after SBT. Methods: The level of FFAs in two groups (depend on LR or non LR), including C 14 , C 16 , C 18∶1 , C 18∶2 and C 20∶4 in plasma were measured by gas chromatography before and day 1, 4, 7, 10 and 14 after the operation. Results: The plasma concentrations of FFAs in LR group were higher than in non LR group. Conclusions: Immediate reconstruction of lymphatic drainage of the intestinal graft after SBT and early EN support will not only provide sufficient energy for host, but also correct the lower concentration of FFAs in plasma effectively.
