辅助生殖技术学龄前单双胎子代的认知发展存在差异么?(英文)简   总被引：1，自引：0，他引：1

Objective： To explore whether there exist differences in cognitive development between singletons and twins born after in vitro fertilization （IVF） or intracytoplasmic sperm injection （ICSI）. Methods： A total of 566 children were recruited for the study, including 388 children （singletons, n=175; twins, n=213） born after IVF and 178 children （singletons, n=87; twins, n=91 ） born after ICSI. The cognitive development was assessed using the Chinese-Wechsler Intelligence Scale for Children （C-WISC）. Results： For all pre-term offspring, all the intelligence quotient （IQ） items between singletons and twins showed no significant differences no matter if they were born after IVF or ICSI. There was a significant difference in the cognitive development of IVF-conceived full-term singletons and twins. The twins born after IVF obtained significantly lower scores than the singletons in verbal IQ （containing information, picture ＆ vocabulary, arithmetic, picture completion, comprehension, and language）, performance IQ （containing maze, visual analysis, object assembly, and performance）, and full scale IQ （P〈0.05）. The cognitive development of full-term sin- gletons and twins born after ICSI did not show any significant differences. There was no significant difference between the parents of the singletons and twins in their characteristics where data were collected, including the age of the mothers, the current employment status, the educational backgrounds, and areas of residence. There were also no consistent differences in the duration of pregnancy, sex composition of the children, age, and height between sin- gletons and twins at the time of our study although there existed significant differences between the two groups in the sex composition of the full-term children born after ICSI （P〈0.05）. Conclusions： Compared to the full-term singletons born after IVF, the full-term twins have lower cognitive development. The cognitive development of full-term singletons and twins born after ICSI did not show any significant differences. For all pre-term offspring, singletons and twins born after IVF or ICSI, the results of the cognitive development showed no significant differences.  相似文献   

科技期刊编辑出版的艺术性     

陈华平 《科技通报》2006,22(2):279-282

依据科学和艺术内在本质的关联,以及科学的艺术诉求与呈现;从科技期刊编辑的主体和客体出发,阐述了科技期刊编辑出版艺术性的内涵以及在相关环节的具体表现,即科技期刊编辑出版的艺术性既指编辑产物——客体(期刊内外形式)细节、局部和整体的艺术呈现与美学蕴涵,也指编辑主体为实现这种美的个性化创造而展开的具有独创性的思维运作过程。科技期刊编辑的艺术性,成就了寓含品牌特征的个性化期刊。  相似文献

傅妍 《教育教学论坛》2020,(3):367-368

国际理解能力是中国学生发展核心素养的核心内容之一,是教育国际化的重要方面。基于国际理解教育的中职英语校本教材开发要遵循恰当处理国际理解教育中全球化和西方化原则,坚持多元文化包容性原则。可以从主题式单元学习、实践性体验学习等方面实施,以求校本课程开发实效,从而帮助学生提升国际视野,发展核心素养。  相似文献   

农业综合类核心期刊“互联网+”发展现状研究     

高峻 《中国科技期刊研究》2017,28(10):941-947

【目的】 了解“互联网+”背景下科技期刊数字化平台的建设情况,分析存在的问题,探索发展策略。【方法】 以农业综合类核心期刊为例,通过联网登录、访问、使用的方式,调查期刊官方网站、微信平台、官方微博及移动客户端建设情况。【结果】 34种农业综合类核心期刊目前都已搭建官方网站,但开通微信公众号的只有16种,开通官方微博者仅5种,运行至今的仅1种,有3种期刊提供移动客户端服务。【结论】 农业综合类核心期刊已基本打造起数字化平台,但“互联网+”背景下的整合发展水平不高。应加强认识,优化顶层设计,推动“互联网+”背景下期刊的融媒体发展。  相似文献

Adsorption of methylene blue onto activated carbon produced from tea (Camellia sinensis L.) seed shells: kinetics, equilibrium, and thermodynamics studies

Tea (Camellia sinensis L.) seed shells, the main byproduct of the manufacture of tea seed oil, were used as precursors for the preparation of tea activated carbon (TAC) in the present study. A high yield (44.1%) of TAC was obtained from tea seed shells via a one-step chemical method using ZnCl₂ as an agent. The Brunauer-Emmett-Teller (BET) surface area and the total pore volumes of the obtained TAC were found to be 1 530.67 mg²/g and 0.782 6 cm³/g, respectively. The equilibrium adsorption results were complied with Langmuir isotherm model and its maximum monolayer adsorption capacity was 324.7 mg/g for methylene blue. Adsorption kinetics studies indicated that the pseudo-second-order model yielded the best fit for the kinetic data. An intraparticle diffusion model suggested that the intraparticle diffusion was not the only rate-controlling step. Thermodynamics studies revealed the spontaneous and exothermic nature of the sorption process. These results indicate that tea seed shells could be utilized as a renewable resource to develop activated carbon which is a potential adsorbent for methylene blue.  相似文献
