目的探讨无症状的双胎妊娠应用阴道分泌物胎儿纤维连接蛋白（fFN）联合经腹宫颈长度预测早产的价值。方法共纳入98例双胎妊娠孕妇，于妊娠24周~35周检测孕妇宫颈阴道分泌物fFN、经腹B超检测宫颈长度并随访妊娠结局。结果 fFN联合宫颈长度检测预测双胎妊娠早产较两项单独检测预测早产的敏感度、阴性预测值均有所提高。结论 fFN及宫颈长度联合检测可用于筛查无症状的双胎妊娠孕妇早产，具有较高的临床应用价值。

Objective To evaluate transabdominal cervical length measurements and fetal fibronectin detection in the maternal vaginal secretions as predictors of preterm delivery in asymptomatic twin pregnancy. Methods A total of 98 cases of twin pregnancy were recruited. Transabdominal ultrasound assessments of cervical length and fetal bronectin detection were performed from 24 to 35 weeks of gestation. The pregnancy outcomes were followed up. Results The sensitivity of detection of cervical length combined with fetal bronectin as predictors of preterm delivery in asymptomatic twin pregnancies was 82.0%, specificity 76.7%, positive predictive value 49.3%and negative predictive value 91.7%. The sensitivity and negative predictive value of the joint tests were higher than that of the respective detection for predicting preterm delivery. Conclusion For asymptomatic twin pregnancy, fetal bronectin detection combined with cervical length measurements can be used for screening of asymptomatic twin pregnancy.
