The mRNA expression on the M1 macrophage (a) and M2 macrophage (b) polarization in the gastric mucosa. Group 1: control group with health subjects; group 2: chronic atrophic gastritis patients without H. pylori infection; group 3: H. pylori-associated chronic atrophic gastritis patients. One-way analysis of variance (ANOVA) was performed to compare the means of these indexes, then the Student-Newman-Keuls (SNK) test was used to determine where the differences were existed between each two groups. *P < 0.05 compared with the group 1. #P < 0.05 compared with the group 2.
