杆菌 (H. pylori) 感染是胃癌 (GC) 的关键风险因素,但并非所有感染的人都会患上这种疾病. 这篇评论探讨了H. pylori的情况.
科学领域:
- 胃肠道学和瘤学
- 微生物学和免疫学
背景情况:
- 胃癌 (GC) 是一个重大的全球健康挑战,特别是在中国.
- 杆菌 (H. pylori) 是已知的GC致癌物,但只有很小比例的感染者会患上这种疾病.
- 阴性 H. pylori GC 的发病率正在上升,需要对替代性致病机制进行研究.
研究的目的:
- 审查H. pylori在胃癌发展中的致病机制,同时考虑细菌毒性因素和宿主易感性.
- 探索潜在的风险因素和导致H. pylori阴性胃癌的机制.
- 为了确定高风险的个人GC和突出未来的研究方向.
主要方法:
- 文献综述侧重于H. pylori毒性因素,宿主遗传易感性和免疫微环境.
- 对H. pylori阴性GC的潜在风险因素的分析,包括其他感染,自身免疫性疾病,胆汁反流和环境影响.
- 综合当前的知识,以阐明跨不同H. pylori感染状态的GC病原体.
主要成果:
- 杆菌通过其毒性因子和调节宿主的遗传和免疫格局,为GC做出贡献.
- 阴性H. pylori的GC可能与其他微生物感染,自身免疫性胃炎,胆汁反流,遗传突变和环境暴露有关.
- 了解这些多样化的机制对于准确的风险分层和个性化的预防策略至关重要.
结论:
- 胃癌的发病因子是多因素的,涉及H. pylori,宿主因素,以及潜在的其他环境或传染病体.
- 未来的GC预防和管理策略必须通过专注于宿主特定因素和H. pylori阴性病例来适应H. pylori流行率的下降.
- 为了应对胃癌研究和临床实践不断变化的环境,必须采取多学科的方法.

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...
Pathophysiology of Peptic Ulcer Disease: Injurious Factors
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...
Gastritis III: Clinical Manifestations and Management
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
