Objective:To study the effect of glutamine nutrition support on the intestinal mucosal barrier function and inflammatory response in patients with severe acute pancreatitis.Methods:Patients with severe acute pancreatitis who were treated in Pengzhou People's Hospital between May 2014 and November 2016 were selected as the research subjects and randomly divided into two groups, control group received conventional symptomatic treatment and conventional enteral nutrition intervention, and Gln group received conventional symptomatic treatment and glutamine enteral nutrition intervention. The contents of intestinal mucosal barrier damage markers and inflammatory mediators in serum as well as the expression of inflammatory signaling molecules in peripheral blood were detected before and after treatment;the number of intestinal flora was detected after treatment.Results:After treatment, LPS, DAO, HBD2, TNF-α, sTREM-1, IL-1β and IL-6 levels in serum as well as TLR4, NF-kB, MyD88 and p38MAPK mRNA expression in peripheral blood mononuclear cells of both groups of patients were significantly lower than those before treatment, LPS, DAO, HBD2, TNF-α, sTREM-1, IL-1β and IL-6 levels in serum as well as TLR4, NF-kB, MyD88 and p38MAPK mRNA expression in peripheral blood mononuclear cells of Gln group after treatment were significantly lower than those of control group, and the number of lactobacillus, bifidobacterium and bacteroides were significantly higher than those of control group while the number of escherichia coli and enterococcus were significantly lower than those of control group.Conclusion: Glutamine nutrition support for severe acute pancreatitis can reduce the intestinal mucosal barrier function injury and inhibit the inflammatory response activation.
