Detailed Description

This study is a case-control study. Patients, according to the pathological results, will be consecutively enrolled and divided into gastric cancer group, gastric precancerous lesions group, and chronic gastritis group. The serum and gastric juice bile acid profiles, gastric microbial composition of each group patients will be detected.
