[摘要]目的 观察胎儿纤维连接蛋白(fetal fibronectin,fFN)检测在早产预测中的临床应用价值。方法 选泽我院妇产科门诊2016年1月~2018年1月收治的孕妇,随机抽取218例,采用酶联免疫吸附法对孕妇的fFN水平进行检测,根据fFN水平,分为两组。其中fFN水平≥50 as/ml为fFN水平阳性组,fFN水平<50 as/ml为fFN水平阴性组。阳性组48例,阴性组170例。对比两组胎儿的早产发生率,并分析fFN水平对胎儿早产的临床预测价值。结果 fFN水平阳性组在7、14 d内、34及37周内的早产率分别为8.33%、12.50%、16.67%、25.00%,均明显高于fFN水平阴性组(0.00%、1.18%、4.71%、11.76%),差异均有统计学意义(P<0.05);fFN指标敏感度为50.00%(30/60),特异度为88.61%(140/158),准确性为77.98%(170/218),阳性预测值为62.50%(30/48)。结论 在早产预测中,fFN检测具有较高的敏感度及阳性预测值,在临床中的使用价值较高,具有推荐应用的价值。

[Abstract] Objective To observe the value of fetal fibronectin (fFN) detection in predicting premature delivery. Methods All the subjects were selected from pregnant women admitted to the Department of Obstetrics and Gynecology clinic from January 2016 to January 2018 in our hospital and 218 were randomly selected. Enzyme-linked immunosorbent assay was used to detect fFN levels in all pregnant women. According to fFN levels, they were divided into two groups. FFN levels ≥50 as/ml were positive for fFN levels, and fFN levels <50 as/ml were negative for fFN levels. A total of 48 pregnant women in the positive group and 170 pregnant women in the negative group were included. The incidence of preterm birth was compared between the two groups of fetuses, and the clinical predictive value of fFN levels for fetal preterm birth was analyzed. Results The results showed that the fertility rates of pregnant women with positive fFN levels group within 7 days, 14 days, 34 weeks, and 37 weeks were 8.33%, 12.50%, 16.67%, and 25.00%, respectively, which were significantly higher than those of fFN levels. There was a significant difference in the data between the groups (0.00%, 1.18%, 4.71%, and 11.76%) (P<0.05). The sensitivity of the fFN index was 50.00% (30/60), the specificity was 88.61% (140/158), the accuracy was 77.98% (170/218), and the positive predictive value was 62.50% (30/48). Conclusion In the prediction of premature birth, fFN detection has higher sensitivity and positive predictive value. It has higher use value in clinical practice and has the value of recommended application.

在临床中,早产属于妊娠常见的一种病理表现,同时也是导致新生儿死亡的主要原因之一[1]。据不完全统计,早产在我国的发病率高达6%~7%,其中在新生儿死亡的总数中,占比高达5%~15%[2]。目前,对于早产的病因机制尚不明确,如何降低妇产科的早产率,属于临床一个重要的问题。尽早产检,使用合理、科学以及有效的检测方法,对降低早产发生率以及提高新生儿生存质量具有积极意义。胎儿纤维连接蛋白(fFN)检测属于临床应用中较为有效的一种检测手段。本研究对fFN检测在早产预测中的临床应用效果进行观察,现报道如下。
