早产的

Objective It is to explore the prognostic value of fetus Fibronectin,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，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。

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。

Pre-production is just speculation, do you have the possibility of premature birth.

预产只是猜测，你有早产的可能。

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.

回顾分析2002 年1月～2007 年12 月我院196 例医源性早产的原因，与487 例自然早产相比分娩方式和新生儿窒息的差异。

A study in press in the Journal of Clinical Psychopharmacology notes that women treated with SSRIs during late pregnancy are more likely to give birth to small and premature babies. A study published in the October 2009 Archives of Pediatric and Adolescent Medicine suggests that women taking SSRIs are twice as likely to have preterm births as compared with the general population and that their babies are more likely to spend time in the neonatal intensive care unit.

在《临床精神药理学杂志》上发表的一项研究指出，怀孕晚期利用 SSRI 类药物治病的妇女更有可能生下体型小和早产的婴儿。2009年10月发表在《儿科与青少年医学文献》上的一项研究表明：服用 SSRI 类药物的妇女早产的可能性是普通人群的两倍，她们的婴儿更有可能要在新生儿重症监护病房度过一段时间。

Many literatures focus on preterm prediction study and evaluate every predictor. The predictors include cervical length and the size of some of fetal organs measured by ultrasound; the level of fFN, IGFBP-1, IL investigated in cervicovaginal fluid, serum relaxin, CRP and HbA1c in mother's blood, MMP-8, MCP-1 and ITAC in amniotic fluid which correlated with infection.

早产的预测是研究热点，大量文献分别从超声测量学角度，包括宫颈长度，胎儿某内脏的测量；宫颈阴道分泌物中多项指标，如胎儿纤维结合蛋白、磷酸化及脱磷酸化胰岛素样生长因子连接蛋白-1、白细胞介素的测定；血生化分析，如血清松弛肽、C反应蛋白、糖化血红蛋白含量的变化及羊水化验与感染有关的一些因子，如快速基质金属蛋白酶8、单核细胞趋化蛋白-1、γ干扰素诱导T细胞α趋化因子等，阐述各指标对早产的预测价值。

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。

the low procreant routeway infection is one important reason to abortion in prevalence.through enhance pertinence treatment to microbe which can cause disease,it might reduce the quotiety of abortion in prevalence.

孕期下生殖道感染是引起孕妇早产的一个重要原因，加强对其中一些高致病性微生物针对性的治疗，可能对减少早产的发生起到重要作用。

In this double-blind study, 142 women with high-risk singleton pregnancies received 100 mg progesterone or placebo daily by vaginal suppository. Between 24 and 34 weeks of gestation, all subjects had uterine contraction monitoring with an external tocodynamometer once weekly for 60 minutes.

对早产的高危险孕妇来说，预防性地在阴道使用progesterone可降低子宫收缩的频率，并减少早产的发生，虽然目前我们还不清楚它的作用机转为何，但我们知道它对子宫肌肉层有2种作用：一为藉由抑制细胞质内动情素受体的取代而抑制动情素发挥作用，另一个则是经由它自身的细胞性受体而直接作用在子宫的生合成路径上。

OBJECTIVES. Preterm male infants are at a disadvantage when compared with female infants regarding the incidence of respiratory and neurologic morbidity and mortality. At term, female infants from unlike-sex twin pairs have birth weights that are closer to their male co-twins than to girls from like-sex twin pairs.

该团队是以研究胎儿的并发症作为切入点的，他们发现早产双胞胎中常见的呼吸窘迫综合症的发病率与胎儿的性别有很大关系，同时，早产的异卵双胞胎中的女性胎儿将丧失她们先天的抵抗呼吸疾病的优势，其中原因便是男性胎儿的存在。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
