ARTICLE HIGHLIGHTS
Research background
In the clinic, neonatal necrotizing enterocolitis (NEC) is a frequently occurring pediatric intestinal inflammatory disease. The mortality of premature infants with NEC is as high as 50%, and the incidence shows an increasing trend, which has serious impacts on the quality of life of children.
Research motivation
This study provides help for the clinical diagnosis and treatment of neonatal NEC.
Research objectives
This study aimed to investigate the expression and significance of mucin 1 (MUC1) and interleukin-11 (IL-11) in the intestinal mucosa of children with neonatal NEC after surgery.
Research methods
Total 48 postoperative intestinal mucosal specimens from children with NEC (NEC group) and 22 intestinal mucosal specimens from congenital intestinal atresia (control group) were collected in our hospital. Immunohistochemical staining and Western-blot technique were used to detect the expression of MUC-1 protein and IL-11 protein in the two groups. The serum levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the two groups were detected by enzyme-linked immunosorbent assay, and the relationship between MUC-1 protein, IL-11 protein and serum TNF-α and IL-1β was analyzed by linear correlation method.
Research results
The protein expression of MUC-1 and IL-11 in the NEC group was significantly lower than that in the control group, and the difference was statistically significant. The levels of serum TNF-α and IL-1β in the NEC group were significantly higher than those in the control group. The protein expression of MUC-1 and IL-11 in the NEC group negatively correlated with serum TNF-α and IL-1β levels. There was a significant negative correlation between the protein expression of MUC-1 and IL-11 and the levels of serum TNF-α and IL-1β in the NEC group.
Research conclusions
The protein expression of MUC1 and IL-11 in the intestinal mucosa of children with NEC is significantly downregulated after surgery. This down regulation may be involved in the pathogenesis of the disease and has a certain correlation with inflammatory response factors in children with NEC.
Research perspectives
MUC1 and IL-11 proteins may be related to the pathogenesis of the disease and have a certain correlation with inflammatory response factors in children with NEC, which has profound clinical significance.
