ABSTRACT
Objective To explore the roles of serum TLR-4, TNF-αand IL-6 in neonates with preterm birth. Methods A total of 120 neonates from neonatology department in the Xingtai People's Hospital were selected and divided into full-term group (n=40), premature rupture of fetal membranes (n=40) and idiopathic preterm group (n=40) based on the gestational age. The peripheral venous blood was collected within 30 minutes when the infants were born, and the supernatant was reserved after centrifuged. The levels of serum TLR-4, TNF-αand IL-6 were detected by enzyme-linked immunosorbent assay. Results The levels of TLR-4, TNF-αand IL-6 in idiopathic preterm and premature rupture of fetal membranes were signiifcantly higher than that in full-term group and showed positive correlation. Conclusion Cytokines TLR-4, TNF-αand IL-6 maybe closely related to the preterm birth.
