- Abstract: Objective To investigate the expression levels and clinical significance of serum and placental microRNA(miR)-1227-3p and miR-212-3p in puerperas with fetal growth restriction(FGR).Methods A total of 120 puerperas diagnosed with FGR and completed delivery in our hospital were included as the study group.Patients were assigned into the mild group(n=72)and the severe group(n=48)according to the severity of their condition.Another 120 healthy puerperas who underwent prenatal check ups and delivered during the same period in our hospital were included as the control group.QRT-PCR was used to detect serum and placental miR-1227-3p and miR-212-3p.The pregnancy outcomes of both groups were recorded,including neonatal weight,1min Apgar score,placental weight and placental volume.Results Serum and placental miR-1227-3p expression levels,neonatal weight,1 min Apgar score,placental weight and placental volume were significantly lower in the study group than those of the control group(P＜0.05),while serum and placental miR-212-3p expression levels were significantly higher than those of the control group(P＜0.05).The expression levels of miR-1227-3p in serum and placenta of the severe group were obviously lower than those of the mild group(P＜0.05),while the expression level of miR-212-3p was obviously higher than those of the mild group(P＜0.05).The expression levels of miR-1227-3p in serum and placenta were positively correlated with neonatal weight,1 min Apgar score,placental weight and placental volume,and the expression levels of miR-212-3p in serum and placenta were negatively correlated with the above indicators(P＜0.05).Multivariate Logistic regression analysis revealed that elevated serum and placental miR-212-3p levels were risk factors for FGR(P＜0.05),and increased serum and placental miR-1227-3p,neonatal weight,1 min Apgar,placental weight and placental volume were protective factors(P＜0.05).Receiver operating characteristic(ROC)curve analysis showed that the diagnostic value of combined detection of serum and placenta miR-1227-3p and miR-212-3p levels for FGR was better than that of single diagnosis.Conclusion The combined detection of miR-1227-3p and miR-212-3p in serum and placenta of FGR puerperas has certain value in the clinical diagnosis of FGR.
