Multiple proinflammatory cytokines and chemokines expression levels in the stomach tissue were analyzed. There are no significant differences in protein levels of IFN-γ, TNF-α, IL-1β, RANTES, MCP-1, MIP-1 α and MIP-1 β among the three groups, while IP-10 and MIG levels were significantly elevated in the non-eradicated group when compared to the two groups that received H. pylori eradication therapy. Data expressed as mean ± SEM (pg/mg protein), SEM: standard error of mean. * P<0.05, ** P<0.01, ***P<0.001 vs H. pylori non-eradicated controls. NS: not significantly different.
