研究目的:

1.探讨自身免疫性胃炎与口腔及胃微生物群的相关性,探寻有助于早期诊断自身免疫性胃炎的微生物标志物。 2.通过对比自身免疫性胃炎患者、幽门螺杆菌(H. pylori)相关萎缩性胃炎患者以及健康对照人群的口腔和胃微生物群组成,明确不同人群中口腔和胃微生物群的差异特征。 3.探究口腔微生物群的变化对胃黏膜的微生态的影响,以及两者的相互作用对自身免疫性胃炎的影响。 4.结合口腔及胃微生物群、血清学、内镜表现、病理表现,构建自身免疫性胃炎的早期诊断模型。  

Objectives of Study:

(1) To investigate the association between autoimmune gastritis and the oral and gastric microbiota, and to identify microbial biomarkers that may facilitate the early diagnosis of autoimmune gastritis. (2) To compare the composition of the oral and gastric microbiota among patients with autoimmune gastritis, patients with Helicobacter pylori (H. pylori)–associated atrophic gastritis, and healthy controls, in order to characterize the distinct microbial features of different populations. (3) To explore the impact of alterations in the oral microbiota on the gastric mucosal microecology, and to elucidate how their interactions contribute to the development of autoimmune gastritis. (4) To construct an early diagnostic model for autoimmune gastritis by integrating oral and gastric microbiota profiles with serological findings, endoscopic features, and histopathological characteristics.
