Design outcomes

Primary

MeasureTime frame
Improvement rate of histological intestinal metaplasia in gastric antrum Definition: In this study, patients with two or more score of intestinal metaplasia score (updated sydney system) in gastric corpus are intervened. After the intervention with berberine group or control group, patients with one or less the score defined as improved. Primary outcome is improvement rate.

Secondary

MeasureTime frame
1.Changes in the composition of gastric microbiota before and after intervention, as well as changes in the occupancy ratio of the constituent bacteria. 2.Change in the histological intestinal metaplasia (body) score before and after intervention. 3.Change in the histological intestinal metaplasia (gastric angle) score before and after intervention. 4.Change in the histological chronic inflammation (antrum) score before and after intervention. 5.Change in the histological chronic inflammation (body) score before and after intervention. 6.Change in the histological chronic inflammation (gastric angle) score before and after intervention. 7.Change in the histological acute inflammation (antrum) score before and after intervention. 8.Change in the histological acute inflammation (body) score before and after intervention. 9.Change in the histological acute inflammation (gastric angle) score before and after intervention. 10.Change in the histological atrophy (antrum) score before and after intervention. 11.Change in the histological atrophy (body) score before and after intervention. 12.Change in the histological atrophy (gastric angle) score before and after intervention. 13.Change in the "Endoscopic findings score for gastric cancer risk" before and after intervention. 14.Change in the endoscopic intestinal metaplasia score before and after intervention. 15.Change in the endoscopic atrophy score before and after intervention. 16.Change in the endoscopic diffuse reddening score before and after intervention. 17.Change in the endoscopic fold thickening score before and after intervention. 18.Change in the endoscopic nodular gastritis score before and after intervention. 19.Change in the expression of the intestinal metaplasia-related marker CDX2 before and after intervention. 20.Change in the expression of the intestinal metaplasia-related marker ISX before and after intervention.
