Abstract
BACKGROUND Sepsis is a systemic inflammatory response caused by infection, which is a common complication after severe infection, trauma, shock, and surgery, and is also an important factor in inducing septic shock and multiple organ dysfunction syndrome (MODS), and has become one of the important causes of death in critically ill patients. Septic patients with gastrointestinal transport function weakened, are prone to malnutrition, resulting in decreased immune function, thereby affecting the therapeutic effect. Clinical practice shows that the nutritional metabolism and immune response of patients with sepsis can be effectively improved by giving alanyl glutamine nutritional support treatment, but there is no evidence of evidence-based medicine. The study carried out in this protocol aims to evaluate the effectiveness of alanyl glutamine in nutritional support therapy for patients with sepsis. METHODS The Cochrane Library, PubMed, Embase, Web of Science, WHO International Clinical Trials Registry Platform, CNKI, CBM, VIP, and Wanfang databases were searched by computer, to retrieve all randomized controlled trials (RCTs) on nutritional support for the treatment of sepsis with alanyl glutamine from the date of database establishment to December 2020. Two researchers independently selected the study, extracted and managed the data. RevMan5.3 software was used to analyze the included literature. RESULTS This study observed the changes of serum albumin (ALB), prealbumin (PAB), hemoglobin (Hb), C-reactive protein (CRP), immunoglobulin (IgG, IgA, and IgM), APACHE II score before and after treatment to evaluate the efficacy of alanyl glutamine in nutritional support therapy for patients with sepsis. CONCLUSION This study will provide reliable evidence for the application of alanyl glutamine in nutritional support therapy for patients with sepsis.

Abstract
BACKGROUND To improve the clinical outcome, immunonutrition (IN) was usually used in the patients undergoing elective gastrointestinal caner surgery. However, its effectiveness remains uncertain. METHODS Randomized controlled trials (RCTs) published between 1995 and 2011 were identified and extracted by two reviewers independently from electronic databases, including PubMed, EMBASE, and Cochrane Library. The quality of included trials was assessed according to the handbook for Cochrane reviewer (V5.0.1). Statistical analysis was carried out with RevMan software. RESULTS Nineteen RCTs involving a total of 2331 patients were included in our meta-analysis. The results showed perioperative IN significantly reduced length of hospital stay (WMD, -2.62; 95% CI, -3.26 to -1.97; P < 0.01) and morbidity of postoperative infectious complication (RR, 0.44; 95% CI, 0.32 to 0.60; P < 0.01) compared with standard diet. Moreover, perioperative IN also significantly decreased morbidity of postoperative non-infectious complication in comparison with standard diet (RR, 0.72; 95% CI, 0.54 to 0.97; P = 0.03). CONCLUSION Perioperative IN is effective and safe to reduce postoperative infection, non-infection complication and length of hospital stay.
