摘要
Bronchopulmonary dysplasia(BPD),also known as neonatal chronic lung disease,is a common respiratory disease in preterm infants.Preterm infants with BPD often exhibit changes in gut and lung microbiota.In recent years,with the development of high-throughput sequencing technology,more and more mechanisms of the gut-lung axis have been confirmed,helping to explore new directions for the treatment of BPD using microecological agents.This paper reviews the roles of gut microbiota,lung microbiota,and the gut-lung axis in the pathogenesis of BPD in preterm infants,providing new research avenues for the prevention and treatment of BPD.
