慢性萎缩性胃炎(CAG)和慢性浅表性胃炎(CSG)是最常见的两种慢性胃炎,它们不但可单独存在,而且常为其它疾病(溃疡、息肉、癌等)的背景。其它类型或可归入此两型、或为特异性、或罕见等,本文不作研究。因CAG.CSG和正常胃粘膜(NGM)之间无绝然界限,CAG、CSG中的轻度、中度、重度之间也无绝然界限,对于一些亦此亦彼的病例往往产生病理诊断的较大差异。本文旨在把模糊数学理论引入本来属于模糊范畴的慢性胃炎病理诊断领域,以便有一个较为统一的科学结果。
Chronic atrophic gastritis (CAG) and chronic superficial gastritis (CSG) are the two most common chronic gastritis. They can not only exist alone, but also often serve as the background for other diseases (ulcers, polyps, cancers, etc.). Other types may be classified as such, or specific, or rare, etc. This article does not study. Because there is no absolute boundary between CAG.CSG and normal gastric mucosa (NGM), there are no absolute boundaries between mild, moderate, and severe in CAG and CSG, and pathological diagnosis often occurs in some cases. The big difference. This article aims to introduce the theory of fuzzy mathematics into the field of pathological diagnosis of chronic gastritis that originally belonged to the fuzzy category, so as to have a more unified scientific result.
