Results and conclusion: The expression of NF-κB p65,TNF-α and IL-8 was higher than that of other groups.They may play a vital role in parturiens with PRD associated with IAI .In the placenta tissues of the mice with PRD associated with simulating IAI, after an application of PDTC, TNF-α and IL-8 decreased and the gestion time could maintain longer.

实验主要结果与结论如下：1、通过检测足月妊娠和早产胎盘组织中NF-κB和细胞因子的表达，发现在感染性早产时，NF-κB和细胞因子TNF-α、IL-8的表达增加，提示NF-κB可能为感染性早产分娩启动的关键环节，炎性细胞因子TNF-α与IL-8在感染性早产中起重要作用。

Preterm labor can be more accurately predicted by combination detection of plasma P-LAP and IL-6. The oversecretion of IL-6 may lead to the decrease of P-LAP, which may be the key factor for spontaneous preterm labor.

对有自发性早产先兆的孕妇进行P-LAP和IL-6联合检测，能更准确地预测早产；IL-6等促炎症细胞因子分泌增多，导致P-LAP水平下降，可能是自发性早产的关键因素。

COX-2 may play an important role in the pathogenesis of premature labor.

COX-2可能参与早产分娩的发动，在早产发病机制中起一定作用。

Methods The causes of 196 cases of iatrogenic preterm labor from January 2002 to June 2007 in my hospital were analyzed retrospectively and 487 controls at spontaneous premature labor group,the delivery mode and neonatal asphyxia were compared.

Incredibly high levels of cocaine — usually coupled with the abuse of other drugs — can lead to premature labor, preterm birth and low birth weight, Stanwood said.

令人难以置信的高水平可卡因-通常加上滥用其他药物-可导致早产，早产和低出生体重，s t anwood说。

Generally speaking, placentalia's premature delivery can be divided into two kinds, premature delivery for abandonment and premature delivery at a cost .

一般地讲，有胎盘动物的早产应该分成两种不同性质的情况，一种是废弃性早产；一种是代价性早产。

Furthermore, the significant risks of low birth weight among all newborns are female sex , maternal age, preterm, maternal pneumonopathy, amniotic fluid anomaly, thalassemia, interogestate smoking, interogestate drink, interogestate drug addiction, had preterm or birth weight, pre-eclampsia, nephritic disease, chronic hypertension, gestation hypertension and cervical incompetence.

其次发现不论在全体、单胞胎及双胞胎上，在早产方面，新生儿性别为男性、产妇身分为本国、产妇年龄、低出生体重、产妇心脏疾病、产妇肺病、产妇羊水异常、产妇海洋性贫血、产妇孕期抽烟、产妇孕期酗酒、产妇药瘾、产妇曾生早产或低出生体重儿、产妇糖尿病、产妇妊娠糖尿病、产妇梅毒、产妇妊娠毒血症、产妇肾脏病、产妇怀孕高血压、产妇子宫颈闭锁不全皆会增加早产的风险。

Results The levels of maternal serum IL-6 and IL-6mRNA of placentae in preterm labor with chorioamnionitis were significantly higher than that of without chorioamnionitis and term labor.
