目的：探讨胎儿纤维连接蛋白（fFN）检测在早产预测中的临床价值。方法：选择2012年06月-2013年12月我院门诊定期产检出现先兆早产症状的孕妇56例（观察组），对其阴道分泌物进行fFN检查，观察其妊娠结局，并与同孕期50例正常孕妇（对照组）进行对比分析。结果：观察组56例先兆早产患者中，fFN阳性27例，阳性率为48．2％，对照组50例孕妇中，fFN阳性者仅为2例，阳性率为4．0％；fFN阳性组临产时孕周＜35w的发生率为78．3％，fFN阴性组临产时孕周＜35w的发生率为21．2％，fFN阳性组明显高于阴性组，差异有显著意义（P＜005）。结论：fFN检测在先兆早产孕妇早产预测中有较高的临床价值。“,”Objective:To evaluate fetal fibronectin (fFN)is detected in the prediction of preterm labor clinical value.Methods:June 2012 December 2013 our clinic regularly for check-emergence of symptoms of threatened premature labor in pregnant women 56 cases (observation group),conduct fFN check their vaginal secretions,observe the pregnancy outcome,and with the same pregnancy 50 cases normal pregnant women (control group)were analyzed.Results:The 56 cases of threatened preterm labor patients,fFN positive in 27 cases,the positive rate was 48.2% inthecontrolgroup50casesofpregnantwomen,fFNpositiveinonlytwocases,thepositiveratewas4.0%;fFNpositivegroupwhenlaborgestation <35wincidenceof78.3%,while negative fFN labor gestational age <35w incidence of21.2%,fFN positive group was significantly higher than the negative group,the diference was significant (P <0 05).Conclusion:fFN detection has high clinical value in predicting preterm birth in threatened preterm labor in pregnant women.
