Methods: The patients with severe acute pancreatitis treated in our hospital between February 2015 and February 2018 were selected and randomly divided into two groups. The observation group received basic treatment combined with enteral nutrition containing dietary fiber, and the control group received basic treatment combined with conventional enteral nutrition. The contents of inflammatory cytokines and intestinal mucosal barrier markers in serum, the number of immune cells in peripheral blood as well as the number of intestinal flora in feces were measured respectively before treatment and 7 d after treatment.Results: Interleukin-8 (IL-8), monocyte chemoattractant protein (MCP-1), soluble intercellular adhesion molecule-1 (sICAM-1), soluble triggering receptor expressed on myeloid cells-1 (sTREM1), endotoxin, D-lactic acid and diamine oxidase (DAO) contents in serum, the number of CD8+T cells in peripheral blood as well as the number of enterococcus and enterobacterium in feces of both groups were significantly lower while the number of CD3+T cells, CD4+T cells, CD19+B cells and CD16+CD56+NK cells in peripheral blood as well as the number of bifidobacteria and lactobacillus in feces were significantly higher after treatment, and IL-8, MCP-1, sICAM-1, sTREM1, endotoxin, D-lactic acid and DAO contents in serum, the number of CD8+T cells in peripheral blood as well as the number of enterococcus and enterobacterium in feces of observation group after treatment were significantly lower than those of control group while the number of CD3+T cells, CD4+T cells, CD19+B cells and CD16+CD56+NK cells in peripheral blood as well as the number of bifidobacteria and lactobacillus in feces were significantly higher than those of control group.Conclusion: Dietary fiber in enteral nutrition can alleviate inflammatory reaction, improve immune response and correct intestinal mucosal barrier dysfunction in patients with severe acute pancreatitis.展开更多
