早产

Objective:To explore the treatment and relationship between premature rupture of fetal membrane, premature labor, threatened abortion and group B streptococcus.

目的：探讨生殖道B族溶血性链球菌感染与胎膜早破、早产、晚期先兆流产的关系，并提出相关干预措施，以降低胎膜早破、早产、晚期先兆流产的发生率。

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。

By Laurie Barclay, MDMarch 27, 2003 A marker for insulin resistance was lower in a group of adolescents that were born prematurely and randomized to an undernutrition cohort, according to the results of a study published in the March 29 issue of The Lancet . The investigators suggest that guidelines advocating nutrition to "normalize" growth in infancy may actually increase adult morbidity and therefore should be changed.

伦敦儿童健康研究院Alan Lucas博士表示，我们的研究结果是否能够普及到足月生产的婴儿仍然需要再做进一步的确认，我们承认早产婴儿与足月生产的婴儿在许多方面都有所差异，尤其是早产本身所引发的医疗问题，不过即使我们研究的结果无法适用於所有婴儿，也仍有大约6%的早产儿发生我们所说的这些状况。

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。

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。

Onservative therapy for CIN has not significant influnce on fertility, while cold knife conization and LEEP conization may increase the premature delivery rate, which may be associated with premature ruption of fetal membrane.

IN保守治疗对于患者受孕能力无显著的影响；宫颈冷刀锥切及LEEP锥切可能增加早产率，早产率的增加可能和胎膜早破的发生有关。

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。

Methods: Sixty-two newborn infants were divided into preterm, asphyxiated preterm and fullterm groups.

取我院新生儿病房住院的患儿共62例，分早产、足月对照、早产窒息3组进行观察。

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。

Preemies, as these premature babies are popularly known, had 你好gher risk of death in c你好ldhood, were less likely to reproduce as adults, had slightly lower educational attainment and, among the women, were more likely to have their own babies born prematurely just as they had been.

未成熟儿通常称为早产儿，儿童期间死亡人数的比率更高，成年后生养力降低，在学术方面的成绩会略低，而且在女子早产儿中，她们长大以后也更容易象她们本身曾被早产同样，也早产出她们本身的小孩儿。

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。
