概括

肠道细菌影响胃肠道多体的发展. 特定的微生物增加了结肠和直肠多的风险,而其他微生物则提供了保护. 这项研究使用门德尔的随机化来确定这些因果关系.

科学领域:

遗传学和微生物学
胃肠病学胃肠病学
人类健康和疾病

背景情况:

肠道菌群因其与胃肠片发展的关联而得到认可.
肠道微生物群和息肉之间的确切因果关系尚不清楚.
胃肠多包括胃,十二指肠,结肠和直肠类型.

研究的目的:

调查肠道微生物群和胃,十二指肠,结肠和直肠中的息肉之间的因果关系.
使用孟德尔随机化 (MR) 分析来评估因果关系.
识别与增加或降低胃肠多的风险相关的特定细菌种群.

主要方法:

使用公开可用的全基因组关联研究总结数据进行了门德尔随机化 (MR) 分析.
肠道微生物群数据来源于国际MiBioGen联盟;胃肠息肉数据来自MRC-IEU联盟.
使用MR-Egger,加权中位数,逆方差加权,简单模式和加权模式技术来评估因果关系,并评估异质性和性.

主要成果:

特定的细菌,如Lachnospiraceae UCG004,Erysipelotrichaceae UCG003,和Veillonella与增加结肠的风险有关.
多雷亚和Clostridium无害菌组显示出对结肠多的保护作用.
艾利森氏菌与增加直肠多菌风险有关,而克里斯氏菌R.7群,帕拉苏特雷拉菌和肠膜菌具有保护作用. 拉克诺斯皮拉属FCS020群,肠杆菌,鲁米诺可可属UCG003,和虫菌是胃和十二指肠多的危险因素.

结论:

这项研究确立了肠道微生物群失调和胃肠道多菌形成之间的因果关系.
特定的细菌种类对各种胃肠道多体的风险和保护起着重要作用.
需要进一步的研究来阐明这些细菌影响多体发育的确切机制.

What is Monogastric Digestion?

What is Monogastric Digestion?

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.

Anatomy of the Intestines

Anatomy of the Intestines

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...
