Zhongguo shiyan zhenduanxue, 2020 氧化三甲胺(TMAO)是在人体摄入富含胆碱、左旋肉碱、卵磷脂等高脂营养物质后经肠道微生物转化后生成三甲胺(TMA),而后在肝脏的作用下生成的一种小分子化合物[1]。有相关研究表明,心血管疾病及不良心血管事件的发生与TMAO的产生、代谢过程相关,因此TMAO或可作心血管疾病诊断及治疗的潜在靶点[2,3]。本文就TMAO的生物学特性及其与心血管疾病的联系进行综述。

罕见病研究自酿酒综合征(auto-brewery syndrome，ABS)是一种罕见且容易被忽视的疾病。某些高产酒精的真菌和细菌在肠道内过度繁殖，产生的内源性乙醇超过肝脏最大代谢能力，使患者外周血中乙醇浓度升高。即使未摄入酒精，患者也会出现类似醉酒的症状，给患者带来各种社交、职业和健康的困扰。本文概述了ABS的诊断及鉴别诊断，揭示了肠道菌群紊乱是ABS的核心，并介绍了涉及对肠道微生态调节的多种干预手段，包括饮食干预、药物治疗、益生菌治疗、粪菌移植和噬菌体治疗等，以期帮助临床医师对ABS进行早期识别和治疗。
