Which regimen is appropriate for Chinese children? There is no large scale, multi center studies in China about treatment, CYP2C19 gene polymorphism, resistance rate and resistance genotype. Investigators want to perform a research to compare four different treatment regimens（triple therapy, sequential therapy, bismuth quadruple therapy and concomitant therapy）as the first-line treatment of Helicobacter pylori in Chinese children and investigation of resistance, impact factors and changes of microbiota after the therapy. The results of the study will provide theoretical basis to make the new guideline of diagnosis and therapy of Helicobacter pylori in Chinese children.
