The Efficacy of Quadruple Therapy Containing Sodium Bicarbonate as the Primary Treatment for Helicobacter Pylori Infection

The goal of this clinical trial is to learn the efficacy of sodium bicarbonate-containing quadruple therapy as the primary treatment for Helicobacter pylori infection. The main questions it aims to answer are: Can sodium bicarbonate replace bismuth or clarithromycin in the classic quadruple therapy for the primary treatment of Helicobacter pylori infection? What is the safety and cost-effectiveness of sodium bicarbonate replacing bismuth or clarithromycin in the classic quadruple therapy for the primary treatment of Helicobacter pylori infection? Researchers will compare sodium bicarbonate replacing bismuth or clarithromycin in the classic quadruple therapy to see the efficacy of sodium bicarbonate as an alternative to bismuth or clarithromycin in the classic quadruple therapy for the primary treatment of Helicobacter pylori infection. Participants will： Take Helicobacter pylori treatment drugs for 14 days Recheck 13C-UBT or 14C-UBT breath test 6-8 weeks after eradication treatment Incidence of adverse reactions (AEs) and patient compliance
