【摘要】 社区获得性肺炎（CAP）是呼吸系统常见病，严重威胁人类身心健康。近年来，随着对CAP发病机制的深入研究，越来越多的证据显示肠道菌群与CAP的发生密切关联。中医“肺与大肠相表里”理论对于肺与大肠在生理与病理的认识为从肠道菌群角度治疗CAP提供新思路。该文从“肺与大肠相表里”理论认识、肠道菌群的组成与功能、肠道菌群丰富度、益生菌数量及维持肠道屏障功能方面论述了CAP与肠道菌群的作用，概括了单味中药、中药复方、中医外治法调节肠道菌群治疗CAP的研究内容，以期为中医药治疗CAP提供新的治疗思路。更多还原

【Abstract】 Community-acquired pneumonia(CAP) is a common respiratory disease and a serious threat to physical and mental health. In recent years,with the in-depth study of the pathogenesis of CAP,more and more evidence has shown that intestinal flora is closely related to the occurrence of CAP. The understanding of the physiology and pathology of the lung and large intestine in Chinese medicine theory of“the interior-exterior relationship between the lung and large intestine” provides a new idea for the treatment of CAP from the perspective of intestinal flora. From the theoretical understanding of “the interior-exterior relationship between the lung and large intestine”, the composition and function of intestinal flora,the richness of intestinal flora,the number of probiotics and the maintenance of intestinal barrier function, this paper discuss the role of CAP and intestinal flora, and summarize the research contents of single Chinese medicine, Chinese medicine compounds and Chinese medicine external treatment regulating intestinal flora in the treatment of CAP,so as to provide new ideas for the treatment of CAP with Chinese medicine.更多还原
