Gastric inflammation induced by Helicobacter pylori may initiate superficial gastritis, which then progresses to atrophic gastritis, gastric epithelial dysplasia, and finally gastric cancer. The pathogenesis of AT. pylori infection is related to its virulence factors, including urease, flagella, vacuolating cytotoxin A and cytotoxin-associated gene antigen. The relevant mechanisms of H. pylori-induced inflammation include activation of nuclear factor-r,B, mitogen-acfivated protein kinase pathway, and oxidative stress. To date, therapeutic strategies and results in this infection remain undesirable. Complicated treatment issues include antibiotic resistance, adverse effects of chemical drugs, and recurrence after operation. Therefore, chemoprevention has been regarded as an important measure, and Chinese medicinal herbs have been the research hotspot.
