Abstract:
Objective Investigate the expression level and clinical significance of microRNA-223-3p(miR-223-3p)in the serum of pregnant women with preterm premature rupture of membranes(PPROM).Methods A total of 91 pregnant women who underwent cesarean delivery at the Xuzhou Maternal and Child Health Hospital affiliated with Xuzhou Medical University between April and September 2023 were selected for the study.This included 60 cases of PPROM and 31 cases of term normal pregnant women as the research subjects.The study group was divided based on the pathological results of the membranes into:PPROM group without histological chorioamnionitis(HCA)(PPROM group,n = 37),and PPROM group with HCA(PPROM+HCA group,n = 23).Serum samples from pregnant women were collected before hospital treatment,and the expression level of miR-223-3p in the serum was detected by quantitative real-time PCR(qRT-PCR).The levels of inflammatory factors such as IL-1β,IL-6,IL-8,and TNF-α in the serum were measured by enzyme-linked immunosorbent assay(ELISA).Results The expression level of miR-223-3p in the serum of the PPROM+HCA group was significantly higher than that of the PPROM group and the normal group(P＜0.05).The expression levels of IL-1β,IL-6,IL-8,and TNF-α in the serum of the PPROM+HCA group were also significantly higher than those of the PPROM group and the normal group(P＜0.05).There was a positive correlation between the expression level of miR-223-3p in the serum of the PPROM+HCA group and the expression levels of IL-1β,IL-6,IL-8,and TNF-α(r = 0.553,0.505,0438,0.656,P＜0.05).Conclusion The upregulation of miR-223-3p in the serum of pregnant women with PPROM+HCA is associated with the severity of inflammation in PPROM.
