Outcome Measures
Primary Outcomes (1)
Eradication rates
Both intention to treat(ITT) and per-protocol(PP) analyses will be used for the assessment of the eradication rates of Helicobacter pylori infection. The ITT analysis includes all randomly assigned patients who take at least one dose of the study medications. The PP analysis is limited to patients who take over 90% of the study medications and complete follow-up.
6 months
Secondary Outcomes (3)
The rate of adverse events happening
6 months
The rate of improving dyspepsia symptoms after Helicobacter pylori eradication.
6 months
The rate of good compliance

Study Arms (1)
14-day modified sequential therapy
EXPERIMENTALAll the participants will go through a gastroscopy. Biopsy specimens will be taken for histologic assessment and rapid urease test. Two additional biopsy samples will be obtained from the antrum and body for bacterial culture and antimicrobial susceptibility test. Liver and kidney function will be monitored by blood test before and after the treatment. Then, patients will receive a 14-day modified sequential therapy for the Helicobacter pylori eradication irrespective of antimicrobial susceptibility test results. The regimen contains rabeprazole, amoxicillin, tetracycline and furazolidone for the first 7 days, followed by rabeprazole,amoxicillin, tetracycline and colloidal bismuth pectin for the second 7 days. Drugs: 1. rabeprazole 10mg bid for 14 days, 2. amoxicillin 1000mg bid for 14 days, 3. tetracycline 500mg qid for 14 days, 4. furazolidone 100mg tid for the firs 7 days, 5. colloidal bismuth pectin 200mg bid for the second 7 days.
Interventions

Then, patients will receive a 14-day modified sequential therapy for the Helicobacter pylori eradication. The regimen contains rabeprazole, amoxicillin, tetracycline and furazolidone for the first 7 days, followed by rabeprazole,amoxicillin, tetracycline and colloidal bismuth pectin for the second 7 days.
Eligibility Criteria

You may not qualify if:
- Patients unable or unwilling to receive gastroscopy.
- Patients treated with H2-receptor antagonist, PPI, bismuth and antibiotics in the previous 4 weeks.
- Patients with gastorectomy, acute GI bleeding and advanced gastric cancer.
