研究联合窄带成像技术(NBI)、Lugol氏液染色及超声微探头序贯检查对早期食管癌及癌前病变的诊断价值。以378例经常规内镜观察有食管黏膜粗糙、糜烂、颜色异常等可疑病变患者为研究对象。可疑病灶先行NBI观察,再行Lugol氏液染色观察,最后行超声微探头扫描,结果发现452处病变。与NBI和Lugol氏液染色相比,常规内镜对早期食管癌及癌前病变较易漏诊。高级别上皮内瘤变均主要表现为NBI I级(71.3%)和Lugol氏液染色I级(82.0%),低级别上皮内瘤变主要表现为NBI和Lugol氏液染色Ⅱ、Ⅲ级。超声微探头对早期食管癌与术后组织病理学检查诊断符合率为82.4%。结果表明,联合Lugol氏液染色及NBI检查能提高早期食管癌及癌前病变的检出率,联合超声微探头检查可增加对早期癌及其浸润程度的判断。  相似文献

The development of children's early numeracy through key stage 1   总被引:1,自引:0,他引:1  
Abstract This paper describes a limited longitudinal study of young children's early numeracy development within three testing cycles, at the mid‐point and towards the end of their reception year (at five years‐of‐age) and again at the mid‐point of Year 1 (at six years‐of‐age), located within the broader context of progress through to Key Stage 1 SAT results (at seven years). Assessment was carried out using the Utrecht Early Mathematical Competence Test (Van Luit et al., 1994). This comprised eight sub‐topics, five items in each, including comparison, classification, correspondence, seriation, counting, calculation and real‐life number problem solving. Broadly, one set of sub‐tests related to understanding of relations in shape, size, quantity and order, whilst a second set of sub‐tests related to basic arithmetic. Three hundred pupils were selected from twenty‐one schools, large and small, from rural and urban areas, with high and low concentrations of children eligible for free school meals and/or with special educational needs, as well as representing a broad range of achievements levels based on standards assessment tasks. Whilst this paper focuses upon the performance of English pupils, reference is also made to the larger European sample which involved children from Flemish‐speaking Belgium, Germany, Greece, Slovenia and the Netherlands. Results showed that children's total scores at around the mid‐point of reception year were indeed predictive of later achievement at the end of KS1 though the combined scores over three testing cycles which extended to the mid‐point of Year 1, were more so. Discriminant analysis confirmed that a combination of a counting sub‐test (one seemed sufficient) and a sub‐test focusing on understanding of relations in shape, size, order or quantity (a different one at each testing cycle), together with the general number knowledge sub‐test was best predictive of final SAT levels. Comparison with the international data set suggested a different trajectory for English pupils, with more of a bias towards arithmetic sub‐tests than their European counterparts who start school later. Moreover, the pattern of dependence of scores on age in which no advantage was found in including any national differences was especially interesting. These findings are discussed within the context of different school start ages and traditions of preparation for formal schooling. Perhaps what emerged most strongly is the need for young English pupils to maintain a broad and balanced early mathematics curriculum, which places appropriate emphasis on practical problem solving.  相似文献

This article examines the hypothesis that there are preliminary stages in problem solving which most chemists neglect when trying to teach their students how to solve problems in introductory chemistry courses. It is during these early stages that relevant information is disembedded from the question and the problem is restructured. Unless students can successfully complete these cognitive restructuring stages, they cannot proceed on to the more analytic stages in problem solving that have received more attention from chemists. Preliminary evidence for this hypothesis consists of linear correlations between student ability to handle disembedding and cognitive restructuring tasks in the spatial domain and their ability to solve chemistry problems.  相似文献

长沙市早期民办大学研究   总被引:5,自引:0,他引:5  
早期民办大学诞生于一个非常特殊的历史时期 ,是在社会对人才和青年对成才的双重需求下产生的。办学中的“挂靠”现象是由当时的历史原因造成的 ;学校的组织形式主要有董事会领导下的校长负责制和校务委员会领导下的校长负责制两种。早期民办大学具有主动适应社会需要 ,富于创新精神 ,白手起家、艰苦创业的特点。长沙市的早期民办大学在中国民办大学发展史上占有重要的地位  相似文献

1992年春,邓小平在南方谈话中,对于社会主义本质做出了"五句话"的概括.这一概括对于我们进一步理解和把握社会主义的本质具有重大的指导意义.但是,这一概括是以社会主义初级阶段理论为立论基础的,并不是对整个社会主义社会阶段的本质概括,对于"什么是社会主义,怎样建设社会主义"的问题也只是做出了初步的回答.客观地讲,这一本质论断只是社会主义本质在社会主义初级阶段的具体表现和反映.  相似文献

周作人在日本留学时对"儿童学"产生了浓厚的兴趣,当时的日本不论是儿童文学创作还是儿童文学研究都领先于中国。周作人回国后前十年对日本儿童文学的译介,尤其是发表在《绍兴教育会月刊》上的三篇译文,分别从趣味性、玩具、儿童争斗等方面探讨儿童教育,为其在"五四"时期提出"儿童的文学"奠定了理论基础。  相似文献
