中文摘要：

目的：应用双抗体一步夹心法酶联免疫吸附（ELISA）实验,研究EN对艾滋病（AIDS）病人细胞凋亡膜表面分子及其配体（FAS/FASL）的影响。方法：检测30例AIDS病人服用EN液前和服用4周后FAS/FASL的指标变化,分析AIDS病人肠道功能的变化情况。结果：AIDS病人应用EN治疗4周后FAS/FASL明显降低,与EN前比有显著性差异（P〈0.05）。结论：EN治疗对AIDS病人的FAS/FASL具有调节作用。

英文摘要：

Objective： To observe the effect of enteral nutrition on intestinal barrier function in patients with AIDS by ELISA. Methods： The level of FAS/FASL was measured in AIDS patients before and 4 weeks after EN. Results ： The intestinal barrier function in AIDS patients was improved after eating Enteral nutrition （ P 〈 0.05 ）. Conclusion ： Enteral nutrition has a regulatory role on FAS/ FASL in AIDS patients.
