多胎产

The results show that:(1) 435 cases of CMN are found in 46, 790 newborns with an incidence of 9.30％;(2) the incidences of CMN are obviously higher in parturients at the age over 35 and under 20 years, in multiple gravidity but primiparity, and in individual labourers and unemployees;(3) the incidences of CMN are...

结果表明，本地区7所医院5年间分娩新生儿46790名，发现各类先天性畸形435例，畸形发生率为9.30％，同时发现产妇年龄大于35岁、小于20岁、多胎初产、个体职业和无业者其新生儿畸形率明显较高；新生儿则以男性、早产儿、低体重儿的畸形发生率较高，差别有统计学意义(P.05或P.01)，产妇不同民族间未发现统计学差别。在先天性畸形的种类构成中，神经系统畸形特别是神经管缺损和脑积水占有重要地位。

The goat in lambing trait is between single-fetus and multi-fetus animals.The study on its reproductive trait is useful for us to further understand animal reproductive physiology theoretically and lay theoretical base for improving the efficiency of animal reproductive rate.

山羊的单胎产仔性能介于单胎动物和多胎动物之间，其生殖特性的研究有助于从理论上对动物生殖生理的深一步认识，也为提高动物的繁殖率奠定理论基础。

Four sheep lines, HU-Yang, Chinese M erino monotocous, Chinese Merino multiparous for wool production and Chinese Merino multiparous for mutton production, were used in this study. Litter sizes were recorded for each ewe in the four lines. Primers for BMP15 and BMPR-IB gene were designed from database sheep sequence and polymorphisms were detected by PCR-RFLP method.

以绵羊BMP15基因和BMPR-IB基因为候选基因，以湖羊、中国美利奴单胎品系、中国美利奴肉用和毛用多胎品系为研究对象，采用PCR-RFLP方法对候选基因进行单核苷酸多态性位点检测和基因型分析，同时研究基因对绵羊产羔数的影响。

Methods A retrospective evaluation was done for all the newborns who were born in the provincial women and children's health care hospital from 1995 to 2004-The morbidity, mortality and fatality rate were calculated for each observed year and different seasons. The influence of gender, body weight, gestational age as well as polyembryony and mode of delivery on the asphyxia was analyzed.

对近10年郑州大学第三附属医院分娩的所有活产新生儿的病历资料进行回顾性分析，计算窒息的发生率、死亡率、病死率，观察上述指标的逐年变化趋势及季节变化的情况，并探讨性别、双／多胎、出生体质量、胎龄分娩方式对这些指标的影响。

Objective To investigate clinical significance of color Doppler echocardiographic diagnosis in prenatal diagnosis of fetal congenital heart disease.Methods 520fetuses in24～40weeks were examined by color Doppler echocardiography on four-chamber views and subcostal views to determine CHD.

目的 探讨彩色普勒超声心动图对胎儿先天性心脏病产诊断的临床意义方法使用彩色多普勒超声诊断仪随机对520例胎龄24～40周的胎儿，在心脏超声四腔观基础上结合多切面观察胎儿心内结构，以确定胎儿有无先心病。

There were two genotypesin China Merino fecundity sheep,the BB and B+ mutation genotype was superior in Chinese merino fecundity sheep,the ewes with genotype BB and B+had 4.0 and 3.5 ovulations,genotype ++ had 1.56 ovulations averagely,The BB and B+ mutation genotypes were 2.44(P.01)and 1.94(P.01)ovulations more than with genotype ++ in the Chinese merino sheep.

绵羊的多胎是绵羊业多产、高产的基础。一般来说，家畜的繁殖性状是受多基因控制的数量性状，传统的选择方法对其遗传进展的改良是很慢的，世代间隔长。分子标记辅助选择为解决这一问题提供了新的方向和契机。

Usually the work of paediatricians often encountered in clinical treatment in children: 2-month-old baby is not laugh, or four five-month-old baby will not rise up the first non-erect, or more than 3-year-old child to walk properly, toe down, heel and could not walk forward, walking instability, the majority of children with mothers who have children with a detailed statement of the history of neonatal asphyxia and abnormal birth processes, such as breech births, adequate presentation production, mothers had pregnancy-induced hypertension or fetal heart rate or pre-B ultra-poor can be seen with cord around neck, wrapped around limbs or broken membrane as early as more than 12 hours and even some more than three days.

通常儿科医生在临床工作中常遇到就诊患儿中有：2个月的小宝宝不会笑，或四五个月的小宝宝不会抬头、头竖不起来，或3岁多宝宝走路不好，足尖朝下，足跟不着地，走路向前冲，走不稳，这些患儿中大多数母亲会详细陈述患儿有新生儿窒息的病史及不正常的分娩过程，如臀位产、足先露产、母亲有妊娠高血压或生前胎心不好或产前B超可见脐带绕颈、缠肢体或羊膜早破超过12小时甚至有的超过3天。
