The pulmonary impairment is more pronounced in IBD patients with active disease than in those in remission. A growing number of case reports show that the IBD patients develop rapidly progressive respiratory symptoms after colectomy,with failure to isolate bacterial pathogens on repeated sputum culture,and often request oral corticosteroid therapy. All the above evidence indicates that the inflammatory changes in both the intestine and lung during IBD. Clinical or subclinical pulmonary inflammation accompanies the main inflammation of the bowel.Although there are clinical and epidemiological reports of chronic inflammation of the pulmonary and intestinal mucosa in IBD,the detailed mechanisms of pulmonaryintestinal crosstalk remain unknown. The lung has no anatomical connection with the main inflammatory site of the bowel. Why does the inflammatory process shift from the gastrointestinal tract to the airways? The clinical and subclinical pulmonary abnormalities,dysfunction,or hyper-reactivity among IBD patients need further evaluation. Here,we give an overview of the concordance between chronic inflammatory reactions in the airways and the gastrointestinal tract. A better understanding of the possible mechanism of the crosstalk among the distant organs will be beneficial in identifying therapeutic strategies for mucosal inflammatory diseases such as IBD and allergy.展开更多

However, with a better understanding of COVID-19, gastrointestinal symptoms such as diarrhea, nausea, and vomiting haveattracted increasing attention. The gastrointestinal tract may be a target organ of severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) infection. The intestinal microecological balance is a crucial factor for homeostasis, including immunity andinflammation, which are closely related to COVID-19. Herbal medicine can restore intestinal function and regulate the gut florastructure. Herbal medicine has a long history of treating lung diseases from the perspective of the intestine, which is called thegut-lung axis. The physiological activities of guts and lungs influence each other through intestinal flora, microflora metabolites,and mucosal immunity. Microecological modulators are included in the diagnosis and treatment protocols for COVID-19. Inthis review, we demonstrate the relationship between COVID-19 and the gut, gut-lung axis, and the role of herbal medicine intreating respiratory diseases originating from the intestinal tract. It is expected that the significance of herbal medicine in treatingrespiratory diseases from the perspective of the intestinal tract could lead to new ideas and methods for treatment.展开更多
