细胞焦亡参与早期子鼠坏死性小肠结肠炎的发病.

Objective To establish a mouse model of necrotizing enterocolitis and detect the key protein molecules in serum of neonatal rats with early NEC, so as to preliminatively determine whether necrotizing enterocolitis is involved in early neonatal necrotizing enterocolitis. Methods The NEC mouse model was established and randomly divided into the experimental group and control group with 12 newborn rats in each group. The neonatal rats in the experimental group were induced into NEC animal models. Blood samples were extracted and the concentrations of IL-18, Gasdermin D and Caspase-1 in serum of all rats were detected by Elisa kit. The concentration of target protein in serum of the two groups was compared, α = 0.05. Results The concentrations of Gasdermin D and Caspase-1 in serum of rats in the two groups were significantly different, with P values of 0.017 and < 0.001, respectively. It could be considered that the concentrations of Gasdermin D and caspase-1 in serum of rats in the experimental group were higher than those in the control group. There was no significant difference in serum IL-18 concentration between the two groups （P = 0.755）. Conclusion Gasdermin D mediated pyroptosis may be involved in the pathogenesis of early NEC.
