ARTICLE HIGHLIGHTS
Research background

Chronic atrophic gastritis (CAG) is a precancerous lesion of gastric cancer. If it is effectively treated, GC will be prevented. So the prevention and treatment of CAG are very important. It needs a good animal model, which can provide etiological research and screening of therapeutic drugs. It is an important tool for studying CAG.

Research motivation

Current animal models of chronic atrophic gastritis are not ideal, long cycle, high cost, difficult to operate, and unstable, so better animal models are needed.

Research objectives

To construct a more rapid, safe, stable and efficient chronic atrophic gastritis model with mice.

Research methods

The mice selected for this method were six-week-old Kunming mice, and Helicobacter pylori, N-methyl-N'-nitroguanidine, and ammonia water were combined to develop a CAG model.

Research results

The method showed slight CAG at the 90th day and moderate CAG at the 120th day.

Research conclusions

The method presented here is more rapid, safe, stable, and efficient.

Research perspectives

Starting from the etiology of chronic atrophic gastritis, the course of the disease is simulated to explore a simple, fast, convenient, and stable method of modelling.
