ABSTRACT
Human breast milk-derived exosomes (HMDEs) are newly discovered active signaling vesicles in breast milk, which are rich in nucleic acids, proteins, and lipids. These exosomes play an essential role in the development and maturation of the intestinal mucosal barrier in newborns. In addition, HMDEs possess distinctive properties that allow for remodeling and modification, thereby are expected to provide more efficient prevention and treatment strategies for neonatal intestinal diseases. This article aims to provide a comprehensive review of the origin, isolation, identification, labeling, structural features, composition, and biological functions, and their unique impact on the intestinal mucosal barrier function in newborns.
ABSTRACT
Objective To explore the cause constituents of neonatal severe hyperbilirubinemia and the clinical efficacy and safety of blood exchange transfusion treatment .Methods 142 neonates with severe hyperbilirubinemia conducted the blood exchange transfusion therapy .The levels of serum total bilirubin ,indirect bilirubin and direct bilirubin and the change of blood routine indica-tors were analyzed before and after blood exchange transfusion .Results The main causes leading to neonatal severe hyperbilirubi-nemia were bacterial infection(28 .20% ) ,glucose-6-phosphate dehydrogenase(G6PD) deficiency(27 .50% ) and pregnant women with ABO blood group incompatibility (16 .20% ) .The levels of serum total bilirubin ,indirect bilirubin ,direct bilirubin and blood routine indicators after operation in neonates with severe hyperbilirubinemia were significantly lower than those before operation , the differences were statistically significant (P<0 .05) .The total bilirubin swap exchange was (54 .40 ± 9 .90)% .The intraoperative adverse reactions rate was 3 .50% .The postoperative thrombocytopenia occurrence rate was 72 .00% .Conclusion The blood ex-change transfusion for treating neonatal severe hyperbilirubinemia possesses has clinical significance ,but the hematology and bio-chemical indicators monitoring should be strengthened for avoiding adverse reactions occurrence .
