非酒精性脂肪性肝病 (NAFLD) 与肠道失调有关,其中微生物失衡使细菌产品能够到达肝脏. 本综述探讨了肠道微生物群如何影响NAFLD的发展以及潜在的治疗策略.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 胃肠病学 胃肠病学
- 微生物学 微生物学
背景情况:
- 非酒精性脂肪肝 (NAFLD) 是全球最常见的慢性肝病,带来了重大的经济和健康挑战.
- 人们对NAFLD的确切病理机制仍然不完全了解.
- 肠道失调,肠道微生物组成的不平衡,经常在NAFLD患者中观察到,并与疾病的发病有关.
研究的目的:
- 阐明肠道微生物群影响NAFLD发育和进展的机制.
- 审查肠道失生症在NAFLD病变发生中的作用.
- 探索肠道微生物组作为NAFLD的非侵入性诊断标记物和治疗点的潜力.
主要方法:

- 它检查了将肠道失调与肠道屏障功能受损和细菌产物的转移联系在一起的证据.
- 该综述分析了调查微生物代谢产物和成分对肝病理学影响的研究.
主要成果:
- 肠道失调有助于NAFLD通过增加肠道透性,导致细菌产品如脂多糖 (LPS) 和乙醇转移到肝脏.
- 这些微生物衍生物质可以引发炎症和代谢功能障碍,促进NAFLD的进展.
- 短链脂肪酸 (SCFA) 和其他微生物代谢物的变化也在NAFLD病变发生过程中发挥作用.
结论:
- 肠道微生物群是NAFLD发展和进展的关键因素.
- 准肠道失调症为新型NAFLD诊断和治疗提供了一个有希望的途径.

In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
