概括
便微生物群移植 (FMT) 在性结肠炎 (UC) 缓解方面显示出适度的益处,特别是在密集治疗方案中. 然而,安全问题和异质结果限制了其在临床试验之外的常规使用.
科学领域:
- 胃肠道学和微生物组研究
背景情况:
- 性结肠炎 (UC) 与肠道微生物组失衡有关.
- 便微生物种移植 (FMT) 旨在恢复UC治疗的肠道平衡.

- 审查随机对照试验 (RCT),元分析和UC的FMT指南.
- 整合机械学的见解到FMT的有效性和安全性.
主要方法:
- 关于RCT的叙述性审查,系统审查,元分析和指导方针.
- 微生物组和代谢学研究的分析.
主要成果:
- 在轻度至中度的UC中,使用聚合多捐赠者材料的强化下部GI FMT疗法显示了适度的无类固醇缓解 (25-32%) 和安慰剂 (5-10%) 在轻度至中度UC中.
- 上部GI输送,口服配方和严格的供体选择产生了不同的结果.
- 响应者显示SCFA产生细菌的移植和恢复胆酸通路.
- 罕见的严重传播需要更严格的供体查.
结论:

Inflammatory Bowel Disease V: Surgical Management
791
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Drugs for Treatment of Ulcerative Colitis in IBD
582
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

What is Monogastric Digestion?
76.7K
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.
