Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: The results of clarithromycin susceptibility test of H. pylori isolates
Description: According to the results of antibiotic susceptible testing, patients who were resistant to clarithromycin were belonged into clarithromycin resistance group.Patients who were sensitive to clarithromycin were belonged into the 7days/10days/14days treatment groups.

Intervention: The result of 13C-urea breath test of patient in 7days/10days/14days treatment groups
Description: The intervention focused on the results from the result of 13C-urea breath test at 8 weeks after treatment in patients. All patients were taking 75mg 13C-urea and analysis with a modified isotope ratio mass spectrometer to determine the 13CO2 content.The successful treatment groups were patients with negative in 13C-urea breath tests.The failed treatment of H. pylori groups were patients with positive in 13C-urea breath tests after the standardized triple therapy treatment.
