临床病理诊断工作中的人文关怀

随着现代医学模式的转化,在临床病理诊断工作中应该更注重人文精神的培养和哲学思维的运用。主要表现为以下几个问题服务意识的树立、诊断技术的抉择、沟通艺术的驾驭、温馨环境的营造、诊断因素的认识、桥梁身份的把握。     

心脑血管疾病防治观的上游与下游

促发心脑血管疾病的多重危险因素属于关系链的上游,糖尿病和代谢综合征属于中游,而心绞痛、心肌梗死和脑卒中属于疾病的下游,干预下游是一种高成本高风险的模式,如将干预重点转移到上游则风险不大,成本低廉,有充分的选择余地.     

浅谈内隐学习在大学英语教学中的应用

内隐学习是一种自动的、不易觉察的、对复杂规律敏感的学习,内隐学习与学科教学的结合是近年来内隐学习研究取得的新进展。结合大学英语教学的实际,对内隐学习在大学英语教学中的应用进行了思考并提出了几点认识。     

不同背景噪音干扰下的数字短时记忆研究

以三种类型(交通噪音、生活噪音、舒缓乐音)三种声级(40.7dBA、56.4dBA、73.3dBA)的环境噪音作为无关声音刺激,考察其对数字短时记忆广度和Sternberg任务的影响,发现:(1)背景噪音的不同对个体数字短时记忆广度影响没有显著差异;(2)背景噪音声级的不同对个体删除极端数值后正确反应的反应时及对“极错总比率”都有显著的影响;(3)对于删除极端数值后的正确反应来说,在不同背景噪音存在下,随着记忆集的增大,反应时仍然呈直线上升趋势。     

时间修饰词内隐记忆的实验研究

用词汇线索联想的内隐记忆实验范型,对48个时间修饰词进行概念启动效应的实验研究,探讨时间修饰词内隐记忆的特点和内隐时间表征存在的可能性。结果表明：学过的词和末学过的词之间词汇线索联想的启动值有显著差异;词汇线索联想和词汇线索回忆两种作业平均击中率的差异效应显著;被试完成两种作业依据的判定标准依次为：词的意义、词的时间属性(长度、时间单位)、过去生活经验等。对时间修饰词的内隐表征进行了初步讨论。     

Cognitive strategies in discourse processing: A comparison of Chinese and English speakers

Three experiments tested the hypothesis that, when processing a normative language, individuals tend to adopt the discourse processing strategies that they use in their native language. In a natural language processing task, native speakers of English and Chinese read English passages that were heavily loaded with zero anaphora. Native Chinese speakers found the passages more comprehensible than did native English speakers, presumably because zero anaphora occurs much more often in Chinese than in English. However, in an artificial laboratory task, native Chinese speakers did not find it easier to recover the missing referents than did native English speakers, suggesting that the two groups were equally capable of reference retrieval although they differed in their natural language discourse-processing strategies. These results suggest that the strategies used for processing foreign-language discourse are influenced by those used to process native-language discourse.This research was supported in part by Dean's Small Grants from the Graduate School of the University of Colorado to Liang Tao and United States Army Research Institute Contracts MDA903-90-K-0066 and MDA903-93-K-0010 to the University of Colorado (Alice Healy, Principal Investigator).We thank Barbara Fox, Lise Menn, and Nanfang Jiang for stimulating discussions about this research.An earlier version of this paper was presented at the First International Conference on Chinese Linguistics held in Singapore, 1992.

Progressive catatonia

We present the case of a young man with a diagnosis of a childhood-onset pervasive developmental disorder who developed a progressive neurologic deterioration with persistent catatonia and right hemiparesis. On his initial evaluation approximately three years after the onset of mutism, he manifested right hemiparesis and catalepsy. Two years later, although catalepsy had subsided, motor function had deteriorated so that he could not use his hands to feed or dress himself. Oral-facialbuccal dyskinesia manifested by blepharospasm and grimacing were present constantly during waking hours. Quantitative electroencephalography demonstrated markedly decreased amplitude, a finding associated with catatonia. Left sural nerve biopsy indicated large axon cylinder degeneration. Left deltoid biopsy demonstrated perimysial fibrosis and type II fiber predominance. Although magnetic resonance imaging of the head without contrast was normal, positron emission tomography indicated hypometabolism of the right cerebral and the right cerebellar hemispheres. The patient continues to deteriorate despite a course of 25 electroconvulsive treatments. He continues to manifest criteria for catatonia including motoric immobility, mutism, and peculiarities of voluntary movement such as prominent grimacing. We suspect an inherited neurodegenerative disorder. Since catatonia is a treatable condition frequently associated with medical and neurological diseases, examination for the features of catatonia must be included in the assessment of patients with progressive brain degeneration. This report is an attempt to clarify the traits of a serious variant of progressive brain degeneration.
