Objective : To compare the fetal fibronectin ( FFN ) with Bishop score for the prediction of successful labor induction .

通过较大样本比较胎儿纤维结合素（FFN）和Bishop评分对预测足月孕妇引产的意义。

Objective To investigate the value of fetal fibronectin ( fFN ) in the cervical secretions in predicting the threatened preterm labor .

目的探讨检测先兆早产孕妇宫颈分泌物中胎儿纤维连接蛋白（fFN）在预测先兆早产的价值。

Combining the FFN determination with Bishop mark could provide the evidence of reliability for the induced labor by Misoprostol in late trimester of pregnancy clinically .

应用FFN测定结合Bishop评分，为临床确定使用米索晚期妊娠引产的安全性提供依据。

The experiment showed that the baking effect was good when FFN was 91 ~ 158 s and the comprehensive baking effect was the optimum when FFN was ( 91 s ) .

实验表明：FFN值的范围在91~158s时，烘焙效果较好，FFN值91s时，综合烘焙效果达到最佳。

Objective To study the relationship of fetal fibronectin ( FFN ), Bacteria vaginosis ( BV ) and chorioamnionitis . To evaluate the diagnostic value of FFN for chorioamnionitis .

目的通过检测胎儿纤连蛋白（FFN）研究细菌性阴道病和绒毛膜羊膜炎的关系，为产前早期诊断绒毛膜羊膜炎提供新方法。

Objective It is to explore the prognostic value of fetus Fibronectin ( fFN ), length of cervix uteri and formulation of cervix infundibulum detected by vagina sonography for premature delivery .

目的探讨检测早产高危孕妇宫颈分泌物中胎儿纤维连结蛋白（fFN），阴道超声检查宫颈长度、宫颈漏斗形成情况预测早产的价值。

Objective : To explore the relation between the expression of blood plasma , cervical secretion FFN and spontaneous parturition , and to provide objective , practical and early operational test methods for the clinical prediction of spontaneous time in labor .

目的：探讨血浆、宫颈分泌物胎儿纤维结合素（FFN）的表达与自然临产的关系，为临床预测自然临床时间提供客观、实用、易操作的检测方法。

Methods : 104 cases that had no less than 40 weeks gestational period and had no contraindications of induced labor were randomly divided into three groups : group ⅰ( 20 cases , FFN negative / Bishop < 7 mark );

方法随机选择无米索引产禁忌证的、孕周≥40周孕妇104例分为3组组FFN阴性/Bishop<7分20例；

Objective : To evaluate the reliability and effectiveness of term pregnancy induced labor by small dosage of Misoprostol using FFN determination and Bishop mark , and to study the indication of induced labor by Misoprostol in late trimester of pregnancy .

目的探讨应用胎儿纤维结合素（FFN）测定结合Bishop评分，对小剂量米索前列醇（Misoprostol简称米索）用于足月妊娠引产的安全性及有效性评价，分析晚期妊娠米索引产指征。

As the track circuit systems are non-linear without any accurate analytical model , with the combination of the advantages of fuzzy inference systems easily expressing knowledge and self-learning capabilities of neural networks , an algorithm using FFN model is proposed for fault diagnosis and prognostics .

由于轨道电路系统具有非线性、无精确解析模型的特点，论文结合模糊推理系统易于知识表达的优点和神经网络的自学习能力，提出了一种基于模糊神经网络模型的故障诊断与预测方法。

Methods : Samples of cervicovaginal secretion were obtained from 43 patients with the diagnosis of threatened preterm labor ( study group ) and 41 pregnant women between the same gestational weeks ( control group ) , FFN and IL-6 were measured by ELISA .

方法：采集43名妊娠28-36周并诊断为先兆早产的孕妇（研究组）和41名同期同孕龄的正常孕妇（对照组）的宫颈阴道分泌物，使用ELISA法测定FFN和IL-6。

Conclusions : The use of Misoprostol was the most safe at the time of FFN positive / Bishop < 7 mark in late trimester of pregnancy , which could be used as the clinical indication of induced labor by Misoprostol in late trimester of pregnancy .

结论晚期妊娠FFN阳性/Bishop<7分时，使用米索引产最安全有效，临床上可作为使用米索引产的指征。
