ABSTRACT
<p><b>BACKGROUND</b>Associations between glutamine (Gln) enriched nutrition support and surgical patients with gastrointestinal (GI) tumor remain controversy. The purpose of this meta-analysis was to assess the effect of Gln enriched nutrition support on surgical patients with GI tumor in term of relevant biochemical indices, immune indices, and clinical outcomes.</p><p><b>METHODS</b>Six databases were systematically searched to find eligible randomized controlled trials (RCTs) from 1966 to May 2014. When estimated the analysis indexes, the relative risk (RR) was used as the effect size of the categorical variable, while the weighted mean difference (MD) was used as the effect size of a continuous variable. Meta-analysis was conducted with Rev Man 5.2.</p><p><b>RESULTS</b>Thirteen RCTs, involving 1034 patients, were included in the meta-analysis. The analysis showed that Gln enriched nutrition support was more effective in increasing serum albumin (MD: 0.10; 95% confidence interval [CI]: 0.02-0.18; P < 0.05), serum prealbumin (MD: 1.98; 95% CI: 1.40-2.55; P < 0.05) and serum transferring (MD: 0.35; 95% CI: 0.12-0.57; P < 0.05), concentration of IgG (MD: 1.26; 95% CI: 0.90-1.63; P < 0.05), IgM (MD: 0.18; 95% CI: 0.11-0.25; P < 0.05), IgA (MD: 0.22; 95% CI: 0.10-0.33; P < 0.05), CD3 + (MD: 3.71; 95% CI: 2.57-4.85; P < 0.05) and CD4/CD8 ratio (MD: 0.27; 95% CI: 0.12-0.42; P < 0.05). Meanwhile, it was more significant in decreasing the incidence of infectious complications (RR: 0.67; 95% CI: 0.50-0.90; P < 0.05) and shortening the length of hospital stay (MD: -1.72; 95% CI: -3.31--0.13; P < 0.05).</p><p><b>CONCLUSIONS</b>Glutamine enriched nutrition support was superior in improving immune function, reducing the incidence of infectious complications and shortening the length of hospital stay, playing an important role in the rehabilitation of surgical GI cancer patients.</p>

<p><b>OBJECTIVE</b>To systematically assess the effect of early enteral nutrition support after gastrointestinal operation on prognosis.</p><p><b>METHODS</b>The Cochrane Library, PubMed, CBM, CNKI, Wanfang, and VIP databases were retrieved via computer system for randomized controlled trails(RCTs) with early enteral nutrition support to patients undergoing gastrointestinal operation. Quality of studies was evaluated by the Cochrane Jadad rating scale. Nutrition indexes, bowel function indices, postoperative complications, health-economics indices were collected. Meta-analysis was conducted with RevMan 5.2.</p><p><b>RESULTS</b>Eleven relevant RCTs studies with 1087 cases were enrolled, including 541 patients in the study group(early enteral nutrition) and 546 in the control group. Meta-analysis showed that patients in the study group had significantly higher levels of plasma albumin and prealbumin than those in the control group(WMD=2.87, 95%CI:1.03-4.71; WMD=0.04, 95%CI:0.02-0.05). The time of postoperative bowel ventilation in the study group was significantly shorter than that in the control group(WMD=4.10, 95%CI:-5.38--2.82). The postoperative complication rate in the study group was significantly lower as compared to the control group(RR=0.64, 95%CI:0.44-0.93).</p><p><b>CONCLUSION</b>Early enteral nutrition support after gastrointestinal operation is safe and effective, which can improve the nutritional status, promote bowel function return, and reduce postoperative complication rate.</p>

Nutritional therapy is the basis for all types of diabetes treatment, but has not been properly applied due to the lack of scientific criteria. In 2010, the China Medical Nutrition Therapy Guideline for Diabetes was successfully developed based on the up-to-dated scientific research evidences (especially those from China) using Oxford Centre for Evidence-Based Medicine grading system. These guidelines cover the nutrition-based prevention and treatment of diabetes and its complication as well as the parenteral and enteral nutritional supports, with an attempt to improve the quality of life and lower the burdens of diabetes and its complications.
