Résumé
Bronchopulmonary dysplasia(BPD)is a common chronic respiratory disease, with high mortality and poor long-term prognosis in surviving children, and there is currently no effective intervention.Breastfeeding reduces the incidence of BPD.These depend on a variety of bioactive substances in human breast milk, such as immunoglobulins, oligosaccharides, exosomes, etc.Exosomes are nano-like vesicle bodies secreted by cells, which participate in information transmission and functional regulation between cells.They have high affinity for the body and can tolerate digestion of gastrointestinal enzymes and stomach acid.These enable them to target lung, liver and other organs smoothly.They are expected to become a new method for the prevention and treatment of BPD.
Résumé
Breast milk contains a variety of bioactive components, which play a vital role in disease prevention and treatment.Among them, circular RNA(circRNA), which is a closed ring structure formed by covalent bonds, has aroused interest because of its conservation and stability.Pediatric researchers should attach importance to studies on circRNA in breast milk, as they may bring new inspiration for breast milk functions.In this article, characteristics and functions of circRNA in breast milk will be investigated, and its research and prospects will be discussed.
