Abstract:
Gastric cancer is a disease with high morbidity and mortality in the world, and also obtains attention in the global medicine. The occurrence of gastric cancer is a multi-stage and multi-factor process. A large number of epidemiological, pathological and clinical evidences have confirmed that the risk of gastric cancer in patients with chronic atrophic gastritis (CAG) is significantly correlated with the mortality of gastric cancer. Gastric mucosal atrophy, intestinal metaplasia (especially incomplete colonic metaplasia) and dysplasia are the main stages of precancerous lesions of precancerous lesions of gastric cancer (PLGC). Monitoring the condition of CAG patients, especially those with intestinal metaplasia and dysplasia, is of great significance for the discovery of early gastric cancer. CAG and PLGC are great significance in the pathological stage of gastric carcinogenesis. In recent years, more and more in-depth clinical and experimental studies have been carried out in this direction. So far, animal experiment is the main research way for CAG and PLGC disease, so it is very important to explore the modeling method. Choosing a stable and reliable model is the primary factor to study animal experiment. In view of the relationship between two diseases, this paper will summarize the methods of establishing animal models for CAG and PLGC in recent years, generally including chemical drug mutagenesis, physical stimulation, immune modeling, Helicobacter pylori infection replication and surgical modeling. Examples would be given for the application of various methods in the previous experiments, and the author would make a brief comment on the merits and demerits of these methods, which have been explored and successfully made by the author. This study would provide certain reference for the establishment and application of animal models in further CAG and PLGC experiments.
