BACKGROUND
The prevention and treatment of Hirschsprung-associated enterocolitis (HAEC) is a serious challenge in pediatric surgery. Exploring the mechanism of HAEC is conducive to the prevention of this disease.
AIM
To explore the possible mechanism of glycyrrhizic acid (GA) and its therapeutic effect on HAEC.
METHODS
We developed a model of enteritis induced by trinitrobenzenesulfonic acid (TNBS) in zebrafish, and treated it with different concentrations of GA. We analyzed the effect of GA on the phenotype and inflammation of zebrafish.
RESULTS
After treatment with TNBS, the area of the intestinal lumen in zebrafish was significantly increased, but the number of goblet cells in the intestinal lumen was significantly reduced, but these did not increase the mortality of zebrafish, indicating that the zebrafish enteritis model was successfully developed. Different concentrations of GA protected zebrafish with enteritis. In particular, high concentrations of GA were important for the prevention and control of HAEC because it significantly reduced the intestinal luminal area, increased the number of goblet cells in the intestinal lumen, and reduced the levels of interleukin (IL)-1β and IL-8.
CONCLUSION
GA significantly reduced the intestinal luminal area, increased the number of intestinal goblet cells, and decreased IL-1β and IL-8 in zebrafish, and is important for prevention and control of HAEC.
Core Tip: As an important late-stage inflammatory mediator, high mobility group box 1 protein (HMGB1) is involved in the occurrence, development and outcome of many chronic inflammatory diseases and autoimmune diseases. Glycyrrhizic acid (GA) is the most widely used HMGB1 inhibitor, which can directly bind to HMGB1 and inhibit its chemotactic and mitotic activity. Here, we constructed a zebrafish Hirschsprung-associated enterocolitis (HAEC) model and used different concentrations of GA for intervention. Through the intervention study, we understood the effects of HMGB1 inhibitors-GA on the phenotype and inflammatory state of HAEC zebrafish, and the study results provided a new reference for the prevention and treatment of HAEC.
