概括
与健康个体相比,壮症患者的肠道微生物组合不同,特定的细菌家族和属有显著差异. 这些组成变化,独立于总体丰度,需要进一步调查它们的临床相关性.
科学领域:
- 微生物组研究的研究.
- 内分泌学 在内分泌学.
- 胃肠病学 胃肠病学
背景情况:
- 肠道微生物群在人类健康中起着至关重要的作用.
- 巨症是一种由生长激素 (GH) 和胰岛素类生长因子-1 (IGF-1) 过量引起的疾病,已与各种代谢障碍有关.
- 然而,对肠道微生物组在壮病中的研究是有限的.
研究的目的:
- 在新诊断患有壮病的患者中描述肠道微生物组的组成.
- 为了比较壮病患者的肠道微生物特征与健康对照者的肠道微生物特征.
主要方法:
- 使用16S rRNA基因扩增序列测序,分析了来自11名积病患者和12名匹配的健康对照者的便样本.
- 参与者在样本采集前三天遵循标准饮食.
- 临床数据,包括体重指数 (BMI) 和年龄,在各组之间进行了匹配.
主要成果:
- 在壮病患者和对照人群之间没有观察到α多样性的显著差异.
- 贝塔多样性分析揭示了微生物社区结构的显著差异,基于贾卡德相似性指数.
- Firmicutes/Bacteroidota比率在壮病患者中较高. 活性细菌的丰富性显著增加,而特定的细菌家族 (Eggerthellaceae,Christensenellaceae,Bacteroidaceae) 丰富,而其他 (Butyricicoccaceae,Tannerellaceae) 减少.
- 在壮病患者中发现了不同的属,包括Prevotella 7和Bacteroides,而Butyrivibrio和Eubacterium eligens组在对照中更为丰富.
- 在骨关节炎亚组的壮病患者中,prevotella_7被丰富了.
- 微生物种群和GH/IGF-1水平之间,以及糖尿病和非糖尿病亚组之间没有发现显著的关联.
结论:
- 肠道微生物组的组成在壮病患者和健康个体之间有所不同,主要是具体的种类而不是整体的多样性.
- 这些组成差异与微生物丰富程度无关.
- 需要进行进一步的前性研究,以阐明肠道失生症在壮症中的临床影响.

71.1K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

71.8K
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...

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...
