概括
乙酸性胃肠道疾病 (EGID) 涉及慢性炎症和乙酸细胞的积累. 虽然一些EGID与食物过敏和TH2炎症有关,但其他如eosinophilic大肠炎 (EoC) 不同,目前的疗法仅部分解决疾病特征.
科学领域:
- 胃肠病学 胃肠病学
- 免疫学 免疫学 免疫学
- 过敏 过敏是一种过敏.
背景情况:
- 生性胃肠道疾病 (EGID) 是一种慢性疾病,其特征是胃肠道症状和生细胞透.
- EGID包括埃索诺菲尔性胃炎 (EoG),埃索诺菲尔性肠炎和埃索诺菲尔性结肠炎 (EoC).
- EoG和eosinophilic双胞胎炎 (EoD) 与食物过敏原和TH2炎症有关,与具有明显分子特征的EoC不同.
研究的目的:
- 为了探索基因表达,TH2免疫反应和EGIDs中的基因病理发现之间的关系.
- 了解EGID亚型之间的分子差异,特别是EoC与EoG和EoD相比.
- 评估目前对EoG的免疫疗法的有效性.
主要方法:
- 对EGID患者基因表达模式的分析.
- 通过不同EGID亚型 (EoG, EoD, EoC) 的转录组数据进行比较.
- 评估组织病理学特征及其与免疫标记物的相关性.
主要成果:
- 与TH2免疫反应相关的基因表达与EoG,EoD和EoC中的特定基因病理发现相关.
- EoC与其他EGID的转录基因重叠很小,这表明了不同的致病机制.

01:20Histology of the Gastrointestinal (GI) Tract
972
The GI tract, from beginning to end, is made up of four continuous tissue layers that adjust their structure according to their specific roles. These layers, from innermost to outermost, are known as the mucosa, submucosa, muscularis, and serosa, which are continuous with the mesentery.
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

01:17Chronic Bowel Disorders: Introduction
450
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:30Other Disorders of Digestive System
826
The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

01:29Gastroesophageal Reflux Disease I: Meaning and Pathophysiology
313
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...

01:29Endoscopic Procedures I: Esophagogastroduodenoscopy
114
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
