Helicobacter pylori (HP) and duodenal ulcer (DU) are closely related. The results showed that in the occurrence of DU, HP in the antral mucosa detection rate as high as 80% or more; and anti-HP treatment, DU can be completely healed. Therefore, people think that HP is an important risk factor for DU. However, the mechanism of DU infection caused by HP infection in antral mucosa is not yet clear. This article aims to hydrogen breath test (BHT)
