摘要	肠易激综合征（irritable bowel syndrome，IBS）是一种常见的功能性肠病，其特征是反复发作的腹痛或腹胀，伴随大便次数和性状改变。最近的研究表明肠道菌群在调节宿主免疫及炎症性疾病的发生和发展中起着重要作用，低水平的炎症会促进真菌定植，而真菌定植则会促进进一步的炎症。免疫激活和炎症反应在IBS的病理机制中十分重要。有研究发现白色念珠菌可以通过念珠菌溶素激活宿主免疫反应、影响紧密连接蛋白的表达、破坏细胞，致使上皮通透性增加和屏障功能被破坏。现阶段IBS治疗方法局限，并且其相关症状显著影响患者的生活质量，因此阐明IBS的机制十分重要。本文综述了近年来国内外对肠道细菌和真菌与IBS关系的研究，旨在为进一步明确IBS的发病机制及找到有效的干预方法提供理论基础。
Abstract	Irritable bowel syndrome (IBS) is a common functional bowel disease characterized by recurrent abdominal pain or bloating, accompanied by changes in the frequency and characteristics of bowel movements. Recent studies have shown that the intestinal microbiome plays an important role in regulating host immunity and the occurrence and development of inflammatory diseases. Low-level inflammation promotes fungal colonization, and it promotes further inflammation. Immune activation and inflammation are very important in the pathogenesis of IBS. Studies have found that Candida albicans can activate the host immune response through candidalysin, affect the expression of tight junction proteins, and destroy cells, resulting in increased epithelial permeability and destruction of barrier function. At this stage, the treatment of IBS is limited, and its related symptoms significantly affect the quality of life of patients, so it is very important to clarify the mechanism of IBS. This article reviews recent studies on the relationship between intestinal bacteria/fungi and IBS in China and the other countries, aiming to provide a theoretical basis for further clarifying the pathogenesis of IBS and finding effective intervention methods.
