No difference of intestinal mucosal barrier function between the two groups before nutritional intervention (P > 0.05); after the nutritional intervention, the patients improved intestinal mucosal barrier function, the observation group, and C-reactive protein and tumor necrosis factor α were lower than the control group, statistically significant (P < 0.05). TNF-α: Tumor necrosis factor α.
