Objective To investigate the effect of mesenteric lymphatic duct liagtion and glutamine enteral nutrition on intestine and distant organs in intestinal ischemia/reperfusion injury. Methods Forty male SD rats undergoing gastrostomy were randomly assigned into 5 groups (n=8): sham operation group, normal enteral nutrition group, normal enteral nutrition+lymphatic duct ligation group, glutamine group and glutamine+lymphatic duct ligation group. Sham operation group only received laparotomy after 7 days of full diet, the other four groups were subjected to 60 min of intestinal ischemia after 7 days of enteral nutrition, and the two lymphatic duct ligation groups were plus mesenteric lymphatic duct ligation. The original nutrition continued 3 days after reperfusion. Intestinal permeability was detected on day 1 before reperfusion, day 1 and 3 after reperfusion. Intestinal morphology was observed, endotoxin, D-lactate and diamine oxidase levels in serum, and apoptotic index in lung tissue were detected on day 3 after reperfusion. Results The intestinal permeability in each group was significantly increased on day 1 after reperfusion (Plt;0.05), and which in normal enteral nutrition+lymphatic duct ligation group and glutamine+lymphatic duct ligation group were significantly decreased on day 3 after reperfusion (Plt;0.05). The mucosal thickness and villus height of ileum and mucosal thickness of jejunium in glutamine+lymphatic duct ligation group were significantly higher than those in other groups (Plt;0.05), and villus height of ileum in glutamine group was higher than that in normal enteral nutrition group (Plt;0.05); those morphology indexes in normal enteral nutrition+lymphatic duct ligation group were higher than those in normal enteral nutrition group, but there was no statistical signification (Pgt;0.05). Apoptosis index of lung tissue in lymphatic duct ligation groups was significant lower than that in no-ligation groups (Plt;0.05). Levels of endotoxin, D-lactate, and diamine oxidase in lymphatic duct ligation groups had downward trends compared with no-ligation groups, but there was no statistical signification (Pgt;0.05). Conclusions Intestinal ischemia/reperfusion injury of rats can cause intestinal permeability increase, bacterial endotoxin translocation and systemic inflammatory response. Mesenteric lymphatic duct ligation and glutamine enteral nutrition intervention can weak lung tissue damage, increase thickness of intestinal mucosa, maintain intestinal barrier function, reduce endotoxin translocation and attenuate systemic inflammatory response. Enteral nutrition with glutamine was better than normal enteral nutrition.

Objective To study effects of enteral immunonutrition and econutrition on intestinal mucosa barrier function in wounded rats. Methods Forty Wistar rats were randomly divided into four groups, with ten rats in each group 〔ie.control group, enteral nutrition (EN) group, enteral immunonutrition (EIN) group and enteral econutrition (EEN) group〕. After gastrostomy, rats in each group were treated with the isocaloric and isonitrogenous nutritional formulas for 7 days, respectively. The morphology of ileum membrane was studied, and the quantities of IgA+, CD3+, CD4+ and CD8+ cells (each HP) of ileum membrane were determined. Results The villus height, crypt depth, mucosal thickness (except EN group) and villus surface area of ileum were increased in EN, EIN and EEN group compared with control group (P＜0.05), but there was no significant difference among the former three groups (Pgt;0.05). The numbers of IgA+, CD3+, CD4+ and CD8+ cells were increased in EN, EIN and EEN group compared with control group (P＜0.05), and those numbers in EN group were lower than those in EIN and EEN group (P＜0.05). Conclusion EIN and EEN may improve intestine mechanical barrier function and promote restoration of small intestine mucous membrane barrier function in rats. EIN and EEN also improve intestine immune barrier function and strengthen its immune function.
目的探讨两种不同途径的营养方式对食管癌患者术后恢复的影响。 方法选取浙江省台州医院心胸外科2007～2011年63例食管癌患者术后的不同营养支持，分为肠内营养（enteral nutrition，EN）组（33例）和肠外营养（parenteral nutrition，PN）组（30例），比较两组的术后胃肠功能恢复、营养指标、并发症情况、住院费用、住院时间及肝功能等影响。 结果EN组与PN组的排气时间[（42.30±6.70）h vs.（60.60±15.60）h，P＜0.01]、住院时间[（15.40±6.55）d vs.（21.00±10.57）d，P＜0.01]、住院费用[（4.49 ±1.28）万元vs.（4.73 ±1.18）万元，P＜0.01]差异均有统计学意义。两组术后均无吻合口漏等严重并发症，两组术后白蛋白水平较术前有不同程度下降，术后肝功能PN组较EN组变化大，两组差异有统计学意义（P＜0.01）。 结论两种营养方式均能改善患者的术后营养状况，但肠内营养更符合生理特点、廉价，适应现代营养支持，较静脉营养有优势。
ObjectiveTo explore the clinical effects of exogenous glutamine on patients suffering from sepsis with hypoalbuminemia in emergency department. MethodsEighty-six patients with sepsis and hypoalbuminemia enrolled from January to November 2013 in the Emergency Department of our hospital were randomly divided into treatment group and control group. Forty-three patients in the control group were given conventional treatments, while the other 43 in the treatment group were treated with glutamine therapy based on the conventional treatments. The clinical efficacy of the two groups including inflammatory markers, albumin level, APACHEⅡ score and SAPSⅡ score, mortality, length of hospital stay were analyzed on day 7, 14, and 28 after being enrolled. A comprehensive analysis of the clinical effects in these two groups was performed. ResultsEighty-six cases were enrolled in this study. The mortality on day 14 and 28 in the treatment group was significantly lower than that in the control group (P<0.05). Inflammatory markers (WBC count, CRP concentration, and PCT concentration) in patients of the treatment group were gradually decreased, whereas serum albumin levels were gradually increased compared with the control group (P<0.05). The cure rate of patients in the treatment group was significantly higher than that in the control group, while the average length of stay was shorter than the control group (P<0.05) on day 28. ConclusionExogenous glutamine supplementation can improve patient cure rates and reduce hospital stays which has good clinical effects on patients with sepsis and hypoalbuminemia in emergency department.

ObjectiveTo explore the effect of early enteral nutrition (EEN) on immune status of patients in intenseive care unit (ICU). MethodsA prospective control study was conducted from July 2011 to December 2012, and 80 patients after trauma and surgery were admitted to ICU. The Patients were divided into EEN group and normal enteral nutrition (NEN) group randomly. Enteral nutrition in EEN group began within 24 hours after admitted to ICU, while within 48 hours in NEN group. ResultsIn 80 patients, 78(37 in EEN group and 41 in NEN group) completed the end point. The baseline in two groups was consistent (P>0.05). The indicators of lymphocyte, IgA, IgG, IgM and CD4+, CD8+, natural kill cell and pre-albumin values in EEN group were higher than those in NEN group (P<0.05). The incidence of diarrhea (8.1%, 26.8%) and infection of wound (2.7%, 17.1%) in EEN were less than those in NEN group. The hospitalization duration in ICU in EEN group[(7.94±3.72) days] was also shorter than that in NEN group[(10.62±3.14) days]. ConclusionEarly enteral nutrition improves immune function and nutrition status in ICU patients; it also protects gut barrier function and reduces the ICU hospitalization duration.
Objective To study the manageable methods, effect of early use of enteral nutrition after operations on esophageal cancer patients. Methods By different way of nutritional support after operation, 209 cases of esophageal cancer were divided into two groups in which enteral nutrition（EN） group,146 cases, were managed with early use of nutritional support through intestine and parenteral nutrition（PN） group, 63 cases, were given nutrition by way of veins. Complications, general recovery and blood biochemical criteria after operation between those two groups were compared. Results No cases of anastomotic fistula occurred in the two groups. The incidence of complications in EN group was significantly lower than that in PN group（P〈0.01）, and the occurrence of diarrhea was higher in EN group （P=0. 000）. The time needed for recovery of bowel sounds, anal exsufflation, defecation and hospital stay was shorter and hospital fee lower in EN group than those in PN group（P=0. 000）. The total amount of gastrointestinal and closed thoracic drainages decreased more significantly in EN group （P= 0. 000） and the value of albumin, globulin and total protein was significantly higher also in EN group （P = 0. 000）. But the amount of BUN, creatinine and neutrophil was significantly lower in EN group （P = 0. 000）. Conclusion Early use of enteral nutrition after operation on esophageal cancer is safe, effective and practical, with more significant advantages than those of parenteral nutrition.
