微生态制剂在肠道疾病治疗中的研究进展

肠道微生态是人体中复杂的生态系统之一。在正常人的肠道内定植大量的细菌，它们不仅可以发挥多种生物学功能，而且与多种疾病有关。然而通过添加微生态制剂，可以明显改善肠道菌群的结构和减少相关致癌代谢产物，同时可以改善某些疾病的临床表现。因此，使用微生态制剂无论对于健康人群还是疾病患者来说，都具有重要的意义。本文通过对肠道菌群相关疾病进行微生态方面的研究进行初步总结，为较全面理解和推广微生态制剂在不同人群中的应用提供思路。

Research progress on application of microecological agents in treatment of gut diseases

Gut microbiota is one of the complicated eco-systems in human body. A large amount of bacteria colonize in the healthy human intestine, which not only play a variety of biological functions, but also are associated with various diseases. By adding microecological agents (probiotics, prebiotics, and synbiotics), we are able to improve the gut microbiota structure and reduce the related carcinogenic metabolites, and also to improve the clinical manifestations of certain diseases. Therefore, it is meaningful to apply microecological agents (probiotics, prebiotics, and synbiotics) both in healthy population and patients. We reviewed the researches on microecological aspect of gut microbiota-related diseases, aiming to shed some light on fully understanding and popularizing of the application of microecological agents among different populations.
