Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Treatment group 1
Based on the infection of Hp or not, patients will receive quadruple therapy (amoxicillin, clarithromycin, pantoprazole, and bismuth) or PPI (pantoprazole) plus taVNS (produced by by Xi'an Bashui Health Technology Co., Ltd) at left tragus. Patients were given taVNS thirty minutes twice a day in the morning and the night for four weeks (duty circle: 30s "on" periods and 30s "off" periods; frequency: 10 Hz; current intensity: minimal pain threshold; pulse width: 500 μs).
taVNS 10
Patients were given taVNS (by Xi'an Bashui Health Technology Co., Ltd) thirty minutes twice a day in the morning and the night for four weeks (duty circle: 30s "on" periods and 30s "off" periods; frequency: 10 Hz; current intensity: minimal pain threshold; pulse width: 500 μs)
Treatment group 2
Based on the infection of Hp or not, patients will receive quadruple therapy (amoxicillin, clarithromycin, pantoprazole, and bismuth) or PPI (pantoprazole) plus taVNS (produced by by Xi'an Bashui Health Technology Co., Ltd) at left tragus. Patients were given taVNS thirty minutes twice a day in the morning and the night for four weeks (duty circle: 30s "on" periods and 30s "off" periods; frequency: 25 Hz; current intensity: minimal pain threshold; pulse width: 500 μs).
taVNS 25
Patients were given taVNS (by Xi'an Bashui Health Technology Co., Ltd) thirty minutes twice a day in the morning and the night for four weeks (duty circle: 30s "on" periods and 30s "off" periods; frequency: 25 Hz; current intensity: minimal pain threshold; pulse width: 500 μs)
Control group
Based on the infection of Hp or not, patients will receive quadruple therapy (amoxicillin, clarithromycin, pantoprazole, and bismuth) or PPI (pantoprazole) plus taVNS (produced by by Xi'an Bashui Health Technology Co., Ltd) at left earlobe. Patients were given taVNS thirty minutes twice a day in the morning and the night for four weeks (duty circle: 30s "on" periods and 30s "off" periods; frequency: 10 Hz; current intensity: minimal pain threshold; pulse width: 500 μs).
Control
Patients were given taVNS (by Xi'an Bashui Health Technology Co., Ltd) thirty minutes twice a day in the morning and the night for four weeks (duty circle: 30s "on" periods and 30s "off" periods; frequency: 10 Hz; current intensity: minimal pain threshold; pulse width: 500 μs)
