Zhao-Yi Lyv1, Liu-Ju Wang1, Mei-Xian Xu1
1of Hebei Children's Hospital, Shijiazhuang 050031, China.
概括
患有败血症的儿童表现出肠道菌群的改变,特定的细菌如Akkermansia减少,Enterococcus增加. 这些肠道微生物组变化与炎症标志物升高相关,表明儿科患者的肠道健康和败血症严重程度之间存在联系.
科学领域:
- 儿科败血症研究研究
- 微生物组分析
- 炎症反应研究 炎症反应研究
背景情况:
- 败血症显著影响儿科健康,肠道菌群的改变可能起到至关重要的作用.
- 了解肠道微生物群在败血症中的作用对于开发向疗法至关重要.
研究的目的:
- 为了研究肠道菌群在患有败血症的儿童的结构特征.
- 确定肠道微生物组组成和儿科败血症炎症反应之间的关联.
主要方法:
- 一项前性队列研究,比较患有败血症和没有败血症的儿童.
- 分析肠道菌群分布,白细胞计数 (WBC),C反应蛋白 (CRP) 和细胞因子水平.
- 便菌群相对丰富度和炎症标志物之间的相关性分析.
主要成果:
- 与非败血症组相比,败血症组显示出较低的阿克尔曼西亚,鲁米诺菌,阿利斯蒂普斯和较高的菌,链球菌,葡萄球菌.
- 在各组之间观察到WBC,CRP,IL-6,IL-10和TNF-α水平的显著差异.
- 肠道菌群的组成,包括Ruminococcus,Alistipes,Enterococcus,Streptococcus和Staphylococcus,与炎症标志物如WBC,CRP和IL-6相关.
结论:
- 患有败血症的儿童存在肠道菌群乱,根据疾病严重程度的变化.
- 肠道微生物组的结构变化与儿科败血症的炎症反应有显著的相关性.

01:23Anatomy of the Intestines
71.7K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

01:17Irritable Bowel Syndrome I: Introduction
265
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

01:17Chronic Bowel Disorders: Introduction
439
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...

01:29Bacterial Flora of the Large Intestine
416
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:30Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
331
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
