盆底结构精细复杂,传统的解剖学以尸检为依据,现代影像学则提供了活体观察功能形态的有效方法.盆底结构核磁共振成像研究的新进展,体现了医学技术创新的稳健性、后发性、综合性,其发展取决于现代科学技术的进步.因此影像医学工作者作为医学科技主体,只有具备综合型知识结构,才能更好地进行医学技术创新. 相似文献

解脲支原体(Uu)感染与不孕不育的关系越来越受到人们的重视,对二者关系的研究,是不断深化发展的过程.Uu能引起输卵管性不孕,且与抗精子抗体产生有关;通过破坏精子形态和功能、降低精子密度或免疫机制致男性不育.提示对于不孕不育患者要应用新技术分型定量检测Uu,严格在循证医学指导下实现个体化综合治疗. 相似文献

We report normative data collected from Mainland Chinese speakers for 232 objects taken from Snodgrass and Vanderwart (1980).
These data include adult ratings of concept familiarity, age of acquisition (AoA), printedword frequency, and word length
(in syllables), as well as measures of rated visual complexity, image agreement, and name agreement. We then examined timed
picture naming of these objects with native Chinese speakers in Beijing in two experiments using line drawings and colored
pictures. In both experiments, the variables name agreement, rated concept familiarity, and AoA made significant independent
contributions to naming latency in multiple regression analyses. We observed a correlation ofr=.85 between naming latency with line drawings and colored pictures and a reduced effect of image agreement on naming when
colored pictures were presented. We discuss the implications of our findings for the study of lexical processing in Chinese.

In this article, we present normative data for 2,423 Chinese single-character words. For each word, we report values for the
following 15 variables: word frequency, cumulative frequency, homophone density, phonological frequency, age of learning,
age of acquisition, number of word formations, number of meanings, number of components, number of strokes, familiarity, concreteness,
imageability, regularity, and initial phoneme. To validate the norms, we collected word-naming latencies. Factor analysis
and multiple regression analysis show that naming latencies of Chinese single-character words are predicted by frequency,
semantics, visual features, and consistency, but not by phonology. These analyses show distinct patterns in word naming between
Chinese and alphabetic languages and demonstrate the utility of normative data in the study of nonalphabetic orthographic
processing. 相似文献

One of the obvious characteristics of the Chinese writing system is its visual complexity. How do children develop their reading and writing ability in such a system? The areas we address in the present study include: (1) The basic unit in character recognition and writing of Chinese children. (2) The role of familiarity of components and the position frequency of components in character recognition and writing. In the first experiment, the subjects were first‐, second‐, fourth‐, and sixth‐graders. Children were asked to delay copy five types of characters: familiar single characters, familiar compound characters, unfamiliar compounds with familiar components, unfamiliar compounds with unfamiliar components, and noncharacters, with the components in impossible positions. The results show that older children were affected more by the familiarity and the position frequency of components in the delayed copy task. In the second experiment, the subjects were from the same grades. Children were asked to carry out lexical decision for five types of characters: real compound characters, pseudocharacters with well‐formed structure and real components, noncharacters with ill‐formed structure but real components, and noncharacters with well‐formed structure but nonreal components. The results show that children can be aware of the ill‐formed structure early, and become aware of well‐formed structure but nonreal components as they grow older. The results suggest that the component of character is the basic unit in children's lexical representation. Familiarity of components and the position frequency of components in characters affect children's character recognition and writing. 相似文献

认知神经心理学为阅读机制的探讨提供了大量的证据,认为不同阅读障碍是不同加工通道选择性受损的结果。近年来,基于联结主义的三角模型理论,研究者提出了主要系统假说(primary system hypothesis),认为阅读障碍是主要的认知系统(如视觉、语义和语音系统)受损导致的:表层障碍是因为语义系统受损导致的阅读困难,语音和深层障碍是语音和语义系统同时受损时综合症状的连续体。该理论认为各主要系统可能同时是多个认知活动的加工成分,一个系统的受损会影响所有与之相关的认知过程,从而把阅读障碍与其它认知功能障碍联系起来。统一的主要系统受损下对各种获得性阅读障碍形成机制在文中得到详细的解释 相似文献
