Taking 300 permanent residents in Xi'an area who will go to the Gastroenterology Clinic of the Second Affiliated Hospital of Xi'an Jiaotong University from February 2022 to March 2023 and undergo 13C-UBT examination as the research object. A questionnaire survey on factors related to H. pylori infection and eradication failure will be conducted. The questionnaire includes basic Information, eating patterns, living environment, related gastrointestinal symptoms, etc. Among the outpatients, H. pylori-positive patients will be given rabeprazole 10 mg + amoxicillin 1000 mg + clarithromycin 500 mg + colloidal bismuth tartrate 220 mg bid for 14 days. After 4-6 weeks of completing eradication therapy, 13C-UBT will be performed to determine whether H. pylori is eradicated. According to the results of 13C-UBT at the beginning and results of 13C-UBT after eradication treatment, outpatients will be divided into three groups: H. pylori negative group, H. pylori positive radical cure successful group and H. pylori positive radical cure failed group.

干预/治疗
无干预：H. pylori negative group
No Intervention
其他：H. pylori positive and successful eradication group
H. pylori-positive patients are given rabeprazole 10mg + amoxicillin 1000mg + clarithromycin 500mg + colloidal bismuth tartrate 220mg bid for 14 days. After 4-6 weeks of completing eradication therapy, 13C-UBT is performed and the result show that H. pylori is eradicated. At the same time, Patients with successful eradication are instructed to conduct 13C-UBT examination after 6 months,1year and every year after drug withdrawal.
药品：PPI quadruple therapy
Among these outpatients, H. pylori-negative patients don't give any intervention. But H. pylori-positive patients are given rabeprazole 10mg + amoxicillin 1000mg + clarithromycin 500mg + colloidal bismuth tartrate 220mg bid for 14 days. After 4-6 weeks of completing eradication therapy, 13C-UBT is performed.
