辅助生殖队列建设在生殖医学研究中的作用

生殖健康事关国计民生。“提高生殖健康水平,改善出生人口素质”,是我国人口健康核心战略。随着我国经济社会快速发展,环境污染和食品安全问题增加,产生大量生殖健康问题。不孕不育已经成为仅次于肿瘤和心血管疾病的第三大疾病,给家庭和社会带来了巨大的负担,阐明不孕不育相关疾病的分子机制并依此提出切实可行的防治对策,有效降低出生缺陷的发生率,是生殖健康与遗传领域亟待研究的课题,也是我国经济与社会发展的重大需求。随着辅助生殖技术的飞速发展,通过该技术出生的婴儿数量逐年上升,然而,与自然出生的婴儿相比,其安全性及伴随而来的子代健康问题亟待评估。本文主要总结分析我国辅助生殖队列建设的必要性和重大意义。     

Coping With the Unexpected in Childbirth: A Thematic Analysis

This article reports original research that describes new mothers'' experiences of birth and maternity care. Qualitative data were collected through a survey on birth satisfaction, which included space for women to provide comments about their birth and experience of care. Thirty-nine women provided comments that were analyzed using the thematic analysis method. Two themes emerged from the women''s experiences: “Unexpected birth processes: expectations and reality” and “Coping with birth: the role of health-care staff.” Participants described unexpected birthing processes, their experiences of care, and maternity care staff''s contributions to coping with birth. Implications for practice for childbirth professionals include promotion of physiologic birth, respectful person-centered care during all phases of perinatal care, and the value of childbirth preparation.

《吕氏春秋》成书年代诸说的清理

由于司马迁在不同地方谈到《吕氏春秋》时,对其成书年代的说法不尽一致,再加上后世一些学者对《吕氏春秋·序意》篇“维秦八年”一语的过分解读,遂致在此书成书年代问题上出现了多种不同的说法。诸说之分歧集中在两个问题上：一是《吕氏春秋》成书于哪一年,二是《吕氏春秋》是否一次成书。而就目前的资料和对这个问题的研究现状来看,在此问题上最可靠的答案是：《吕氏春秋》是在吕不韦任秦相国期间组织宾客一次编撰完成,书成于秦王政八年。学者们在此问题上的意见和分歧,反映了在考证古书成书年代时,内考证与外考证既可能交相为用,也可能相互干扰,导致循环论证。     

南朝文士沈炯生平及其诗文三题

沈炯生于梁朝开国之初,卒于陈文帝天嘉元年春。其作于梁敬帝绍泰二年的《长安还至方山怆然自伤诗》,旨在凭吊故主王僧辩。曾经激扬文字于梁末陈初乱离之际的他,其实只是工笔之才而非善文之士。     

《尚书·胤征》的成书年代——一个语言学的考察视角

自宋以来,学界对<古文尚书>的真实性多有怀疑,清人阎若璩著<尚书古文疏证>,判定<古文尚书>为"伪古文".然而,近年来,有些学者对"伪书"、"辨伪"态度有所改变,认为<古文尚书>并非伪书,<尚书古文疏证>所定之案是一个错误结论.前人的讨论,涉及多个方面,然鲜少语言学的角度.本文以<胤征>为例,探讨<古文尚书>的成书年代.通过文献调查,发现"火炎昆冈"、"玉石俱焚"、"猛火"、"天戒"、"常宪"五个词语,都不见于先秦文献,而见于东汉或西晋等的典籍.虽不能就此判断<胤征>为伪书,但可以推断<胤征>的最后成书可能在东汉魏晋时期.另外,从汉语史的角度来说,也不能够认为<胤征>所反映的都是先秦时期的语言现象.
