肠内营养乳剂对糖尿病患者术后肠黏膜通透性及免疫功能的影响

目的评估肠内营养乳剂对糖尿病患者术后肠黏膜通透性及免疫功能的影响。方法将80例接受非肠道手术治疗的糖尿病患者随机分为肠内营养组（n=40）和对照组（n=40），分别在术后给予肠内营养乳剂和单纯肠外营养治疗，测定两组患者术前、术后第1和8天的尿乳果糖／甘露醇（L／M）值及血免疫功能指标。结果术后第1和8天，肠内营养组的L／M值均明显低于对照组和术前（P均〈0．05）；术后第8天肠内营养组的IgG明显高于对照组（P=0．02）。结论肠内营养乳剂可降低肠黏膜通透性，提高患者免疫功能。

Effect of enteral nutrition emulsion on the immunologic function and intestinal mucous barrier in diabetic patients

Objective To evaluate the effect of enteral nutrition emulsion on the immunologic function and intestinal mucous barrier in diabetic patients. Methods Eighty diabetic patients were randomly divided into con-trol group (n=40) and enteral nutrition group (n=40). The urine lactulose (L) and mannitol (M) levels and the blood immunologic indicators recorded on day 1 and day 8. Results The L/M ratio was significantly lower in enteral nutrition group than in control group on day 1 and day 8 ( P < 0. 05 ). The IgG level was significantly higher in enteral nutrition group than in control group on day 8 ( P = 0. 02 ). Conclusion Enteral nutrition emulsion can decrease the permeability of intestinal mucous membrane and improve the immunologic function in diabetic pa-tients.
