应用超声探测胎儿股骨长度估计妊娠周数

open access: yes, 1985
了解胎儿在子宫内的生长发育是否符合妊娠周数,对妊娠期的正确处理具有重要的意义。估计妊娠周数的方法有多种,利用超声探测是一种较为准确的方法。妊娠13周前超声测量胎儿顶臀长度,和妊娠26周前测量胎头双顶径均比较准确。但亦有认为在27周后超声测量胎头双顶径的准确度则明显下降。最近,一些学者提出妊娠中期的前半段超声测量胎儿股骨长度可以更准确地推测妊娠周数 ...

育儿风格对儿童发展的影响

open access: yes, 2001
回顾了近30年来国际有关育儿风格与儿童发展之关系的研究,包括育儿风格与儿童的学习成绩、社会能力、心理健康、人格特征及育儿风格与亲子关。在学校学习方面,研究者发现权威型育儿风格与儿童和青少年更高的演绎推理能力、更强的优胜动机、较低的考试焦虑和使用更好的教室策略有关。在社会行为方面,权威型育儿风格与儿童延迟满足有关,儿父母高压、缺乏应答、高度心理控制这些因素与儿童的公然攻击行为有关。不当的育儿风格引起儿童的自恋人格障碍、多动症、A型行为、自尊、抑郁、自杀等。在亲子关系方面,权威型父母与子女的关系更好 ...

胎儿大脑化学元素的时序变化特征与成人疾病成因的探讨

open access: yes, 2003
为探讨胎儿大脑化学元素的时序变化特征与成人疾病源于胎儿期的成因 ,分析了 4~ 1 0月龄胎儿大脑 2 1个元素与发育时序的关系 ,并与心、肝、肺、肾、脾、胃相比较。结果表明 ,胎儿大脑 2 1个元素的浓度多数低于成人 ,并随月龄而变化。与发育时序的关系可分为 3种类型 ,其中呈显著正相关和相关不显著的元素占 76 2 % ,在 7种组织中比例最高 ,呈显著负相关的元素在所有组织中比例最低。呈显著正相关的 4个元素除Mn的变化与肺相同外 ,Cu、Cr、Ti与其他组织均不相同 ;呈显著负相关的 5个元素 ,
