Objective To explore the effect of different nutrition on the immune function of patients with colorectal cancer. Methods A total of 640 colorectal cancer patients were randomized into the enteral nutrition and peripheral nutrition groups. The peripheral venous blood was sampled before operation and on the postoperative days 1 and 7 to determine the serum levels of IgG, IgA, IgM, the percentage of T lymph cell subgroups CD3, CD4, CD4/CD8 and CRP, PGE, α- antitrypsin etc. The patient’s general condition, side-effects, and complications were observed intimately after surgery. Results Compared with the control group, the IgG, IgA, IgM, CD3, CD4,CD4/CD8 levels of the trial group on postoperative day 7 were higher. But the levels of CRP, PGE, α- antitrypsin were decreased. Hospitalization time and anal exsufflation time were shorter as well. There was no significant difference in either the general conditions or complications between the two groups. Conclusion Application of enteral nutrition after colorectal cancer surgery is safe, ,effective, and can improve the patient’s immune function and prognosis.
【摘要】 目的 探讨比较全肠内营养支持和全肠外营养支持对急性重症胰腺炎（severe acute pamcreattis，SAP）预后的影响。 方法 将2003年1月-2008年12月收治的54例SAP患者于入院后第1周内随机分为两组:全肠内营养（A）组27例；全肠外营养（B）组27例。两组患者均静脉给予广谱抗生素预防感染。入院时CT扫描及C反应蛋白水平显示两组患者具有可比性。 结果 B组22例患者发生器官衰竭，明显高于A组（5例）。B组22例患者接受了手术治疗，A组手术患者6例（Plt;0.05）。A组患者胰腺坏死后感染发生率明显低于B组（Plt;0.05）。B组患者死亡率高于A组（Plt;0.05）。 结论 全肠内营养支持，不仅可以促进肠道功能的恢复和营养状况的维持，还可减少肠源性感染的发生率，对减少SAP的感染性并发症和病死率具有积极作用。【Abstract】 Objective To evaluate the effects of total enteral nutrition and total parenteral nutrition on the prognosis on severe acute pancreatitis (SAP). Methods A total of 54 patients hospitalized from January 2003 to December 2008 were enrolled. In the first week of hospitalization, the patients were randomly divided into two groups: 27 patients in total parenteral nutrition group (group A) and 27 patients in total enteral nutrition group (group B). All patients were administered with sufficient prophylactic antibiotics. The results of CT scan and C-reactive protein levels were comparable between the two groups. Results Twenty-two patients had organ failure in group B, which was much higher than that in group A (five patieuts). The numbers of the patients undertwent surgical intervention in group A and B were 22 and 6 (Plt;0.05). The incidence of infection after pancreatic septic necroses in group A was obviously lower than that in group B (Plt;0.05). The mortality in group B was apparently higher than that in group A (Plt;0.05). Conclusion Total enteral nutrition support can not only promote the functional recovery of intestinal tract and sustain the nutrition of human body,but also decrease the incidence of enterogenic infection.
【Abstract】ObjectiveTo explore the mechanisms of anabolism intensified by recombination human growth hormone (GH) on the basis of total parenteral nutrition (TPN) during postoperative in gastrointestinal carcinoma patients. MethodsNinety-four gastrointestinal carcinoma patients undergone operation were randomly divided into TPN group and TPN+GH group. The levels of TNF-α, IL-1, IL-6 and CRP were detected in the first, third, seventh postoperative day. ResultsThe levels of TNF-α, IL-1, IL-6 and CRP were significantly lower in TPN+GH group than those in the TPN group at the first, third, seventh postoperative day （P＜0.01）. The levels of TNF-α, IL-1, IL-6 and CRP were significantly higher at the indicated time of postoperative days than the pre-operative days in the two groups (P＜0.01）. ConclusionBy inhibiting TNF-α, IL-1, IL-6 and CRP production in gastrointestinal carcinoma patients undergone operation and blocking high catabolism induced by inflammatory cytokines, GH promotes the synthesis of anabolism.

ObjectiveTo study the protective effect of hepatocyte growth factor(HGF) on grafted mucous membrane of transplanted small bowel.MethodsTotal small bowel transplantation was made in inbred Wistar (RT1k) rats heterotopically,either total parenteral nutrition (control group,n=10) or hepatocyte growth factor supplemented TPN (HGF group,n=10) was given to the recipients from the 2nd day to the 10th day postoperatively. Morphological parameters of the transplanted intestinal mucosa, such as mucosal villous height, villous width, crypt depth, mucosal thickness and villous surface area were observed. Variation of ultrastructure of transplanted epithelial cells was observed. Composition of mucosal protein and DNA content were tested. ResultsComparison between HGF group and the control group were as follows. Mucosal villous height (298.79±22.31） μm vs （176.45±14.62） μm, P=0.001, villous width (107.46±12.34） μm vs （74.20±16.85） μm, P=0.004, crypt depth (104.56±11.17） μm vs （74.45±8.34） μm, P=0.000 5, mucosal thickness (409.53±35.83） μm vs （259.38±24.65） μm, P=0.003, and villous surface area (0.101±0.011) mm2 vs (0.041±0.005) mm2, P=0.001 were found significantly increased in HGF group compared with control group, there were no obvious difference decrease as compared to pretransplant parameters.Mucosal protein composition was higher in HGF group than that in control group （89.65±9.28) mg/g wet wt vs (53.73±11.45) mg/g wet wt, P=0.012, baseline (92.64±10.52) mg/g wet wt, nearly equal to baseline; DNA composition was also high in HGF group （0.89±0.09) mg/g wet wt vs (0.51±0.06) mg/g wet wt, P=0.008, baseline (0.91±0.09) mg/g wet wt. Nearly normal ultrastructure of the graft was maintained in HGF group, atrophied microvilli and broken mitochondrial crista were observed in control group.ConclusionHepatocyte growth factor can improve mucosal structure, preserve enterocyte ultrastructure of isograft after small bowel transplantation in rat.
ObjectiveTo investigate the clinical advantages of enteral nutrition (EN) for acute pancreatitis（AP）comparing with parenteral nutrition (PN) and its prospect. MethodsLiteratures using MESH Browser in Medline were collected and reviewed. ResultsBeing of much higher cost and complications, total parenteral nutrition (TPN) ever regarded as most importantly for AP nutritional support, is now challenged by EN. Clinical evidence suggests enteral (jejunal) nutrition may diminish intestinal permeability to endotoxin and diminish bacterial translocation, thus reducing the cytokine drive to the generalized inflammatory response and preventing organ dysfunction, as well as achieving “pancreatic rest” equivalent to the TPN. Conclusion Early enteral nutrition should be used preferentially for patients with severe acute pancreatitis without paralytic ileus.
To study the effects of arginine supplementation in total parenteral nutrition (TPN) on lymphocytic immune function in postoperative patients with gastric cancer. Thirty six patients with gastric cancer receiving TPN were eligible for entry into randomized and prospective clinical trial of the study. T cell subsets, NK cell activity, plasma IL-2 content and peripheral blood CD25 were measured in before and after parenteral nutrition of the patients. Results: usual TPN could not improve lymphocytic immunosuppression of postoperative patients with gastric cancer. The patients receiving arginine supplementation in TPN might enhance lymphocytic immune function by increasing CD4 level, IL-2 production and NK cell activity, but there was no significant effect of arginine on CD25 expression. Conclusion: there are some effects of supplement with arginine on releasing of the cellular immunosuppression and restoring of lymphocytic immune function.
Forty critical patients with respiratory failure in the intensive care unit were randomly divided into two groups,Group A with administration of parenteral nutritino(PN) and Group B,no parenteral nutrition given.Blood gas analysis and respiratory monitoring showed that the respiratory rate,pH、PaO2、PaCO2 and HCO3- had no marked difference between the two groups.But in Group A there was a slight decrease of Pao2/FiO2 and a marked increase of A-aDO2 and the pulmonary shunt.This study indicates that the content of fat emulsion and hydrocarbon in PN may be the main factor that affects the respiratory function.
1993年10月至1994年2月对中—长链脂肪乳剂(实验组，n=40)和长链脂肪乳剂(对照组，n=30)在静脉营养中的疗效进行了对比观察。从术后第1天起，除从周围静脉输注必需液体外，每日静滴中—长链或长链脂肪乳剂500～1000ml，连续3～5天。监测项目包括血压、脉搏、呼吸、体温、血红蛋白、白细胞、肝肾功能、血甘油三酯及血胆固醇。结果显示：两组均无全笛反应；在输脂肪乳剂后6小时，两组血甘油三酯含量均明显升高，并于12小时时达峰值，16小时时已明显下降，但对照组明显高于实验组(Plt;0.05)，24小时时仍维持较高水平。由此表明，中—长链肪乳剂较易从血清中清除；中链甘油三酯能快速进入线粒体被氧化供能，不依赖内毒碱的转运，能经肝脏生成更多的酮体，极少再脂化为脂肪贮存起来。
