概括
糖尿病导致的口腔和肠道细菌的变化,特别是Fusobacterium nucleatum和Lactobacillus,加剧了心脏损伤. 针对这种口腔肠道微生物群轴可以预防糖尿病患者的心脏损伤.
科学领域:
- 微生物组研究的研究.
- 心血管疾病是什么心血管疾病
- 糖尿病是一种糖尿病.
背景情况:
- 糖尿病是全球冠状动脉疾病的主要原因.
- 糖尿病冠心病 (DCHD) 涉及代谢功能障碍和心血管并发症之间的复杂相互作用.
- 了解口腔和肠道微生物群在DCHD中的作用对于开发向疗法至关重要.
研究的目的:
- 描述DCHD患者的口腔和肠道微生物群.
- 在糖尿病心肌缺血-再输损伤 (MIRI) 的背景下研究口腔肠道微生物群轴.
- 为了确定微生物失生症和MIRI易感性之间的因果关系.
主要方法:
- 使用元基因组测序和qPCR分析了来自DCHD患者的口腔 (舌头涂层) 和便样本.
- 一个小鼠模型的糖尿病MIRI是建立使用链条毒素.
- 干预研究涉及抗生素治疗和特定细菌或微生物群的测试,以阐明口腔肠轴机制.
主要成果:
- 特定的微生物特征,包括口服的Fusobacterium nucleatum和肠道Lactobacillus,被确定为DCHD的潜在生物标志物.
- 在DCHD患者中观察到口服F. nucleatum和肠道Lactobacillus水平的增加,显示出正相关性.
- 在高血糖小鼠中,高口服F.核与口腔肠轴不平衡相关,心脏miRNA-21增加,并加剧了MIRI.
结论:
- 口腔肠道微生物群轴的调节失调在糖尿病中很明显.
- 增加的口服F.核和肠道乳杆菌在加剧MIRI中发挥着关键作用.
- 准口腔肠道微生物群轴为DCHD预防和治疗提供了一个有希望的策略.

What is Monogastric Digestion?
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.

Pathophysiology of Diabetes
924
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
