口腔修复诊疗中人的审美形式感的产生

当前,医学美学作为技术美学涵盖下的一个分支,在口腔修复诊疗工作中,起着从未有过的重要作用。它以哲学的研究方法,运用艺术的手段,正自觉或不自觉地影响着口腔医护人员的工作。本文以口腔诊疗活动中形式美的审美为基点,讨论了几个有关的问题。     

8─11个月婴儿迂回行为发展特点与学习能力的研究

采用程序标准化的婴儿迂回行为测验,探讨了２４４名８－１１个月婴儿的迂回行为发展特点及学习能力。结果表明：（１）８－１１个月婴儿的迂回行为水平表现出随婴儿月龄的增长而提高的趋势。（２）８－１１个月的婴儿具有从反复尝试中学会迂回行为的可能性,其中９、１０个月的婴儿的学习可能性较大,而８个月婴儿的学习可能性较小。（３）８－１１个月婴儿的学习速度随月龄增大而提高。     

大学生社交网站使用与依赖:积极自我呈现的中介效应与关系型自我构念的调节效应

采用问卷法对658名具有社交网站使用经验的大学生进行调查,考察大学生社交网站使用与依赖的关系、积极自我呈现的中介作用以及关系型自我构念的调节作用。结果发现：（1）社交网站使用能显著正向地预测大学生社交网站依赖;（2）积极自我呈现在社交网站使用与依赖的关系中起部分中介作用;（3）积极自我呈现的中介作用受到关系型自我构念的调节。具体来说,相对于高关系型自我构念的大学生,低关系型自我构念大学生的社交网站使用更多地通过积极自我呈现影响其社交网站依赖。     

比较视阈的中美医学伦理学教学——以武汉大学与芝加哥大学为例

中美两国都很重视医者人文素质的培养, 都重视医学伦理学教学。在与芝加哥大学的交流活动中, 武汉大学积极总结经验, 锐意改革, 取得了若干成果。其值得推广的经验包括:注重医学伦理教育的持续性, 构建长效教育机制;注重医学基础课程的道德教化功能, 形成隐性的医德渗透机制;注重临床医生的参与, 确立理论与实践的融通机制;审视中国传统文化特色与医疗现状, 培育域外教学方法的本土化机制;重视医学伦理学学科建设, 建立生命伦理学与医学伦理学的整合机制。     

医科大学生在农村进行艾滋病防治干预模式的探索

艾滋病在中国正处于快速蔓延期,目前艾滋病的宣教和干预,集中在年底艾滋病日前后,集中在大城市,基层农村做得很少.而国家每年培养的数以万计的医科类大学生却没有充分发挥作用.有鉴于此,特组织策划2007防艾乡村大讲堂活动以探索医科大学生在农村进行艾滋病防治干预的新模式.

Velocity dependence of the interocular transfer of dynamic motion aftereffects

It is well established that motion aftereffects (MAEs) can show interocular transfer (IOT); that is, motion adaptation in one eye can give a MAE in the other eye. Different quantification methods and different test stimuli have been shown to give different IOT magnitudes, varying from no to almost full IOT. In this study, we examine to what extent IOT of the dynamic MAE (dMAE), that is the MAE seen with a dynamic noise test pattern, varies with velocity of the adaptation stimulus. We measured strength of dMAE by a nulling method. The aftereffect induced by adaptation to a moving random-pixel array was compensated (nulled), during a brief dynamic test period, by the same kind of motion stimulus of variable luminance signal-to-noise ratio (LSNR). The LSNR nulling value was determined in a Quest-staircase procedure. We found that velocity has a strong effect on the magnitude of IOT for the dMAE. For increasing speeds from 1.5 deg s(-1) to 24 deg s(-1) average IOT values increased about linearly from 18% to 63% or from 32% to 83%, depending on IOT definition. The finding that dMAEs transfer to an increasing extent as speed increases, suggests that binocular cells play a more dominant role at higher speeds.

Cocaine-induced brainstem seizures and behavior.

A variety of abnormal sensory/motor behaviors associated with electrical discharges recorded from the bilateral brainstem were induced in adult WKY rats by mechanical (electrode implants) and DC electrical current stimulations and by acute and chronic administration of cocaine. The electrode implant implicated one side or the other of the reticular system of the brainstem but subjects were not incapacitated by the stimulations. Cocaine (40 mg/kg) was injected subcutaneously for an acute experiment and subsequent 20 mg/kg doses twice daily for 3 days in a chronic study. Cocaine generated more abnormal behaviors in the brainstem perturbation group, especially the electrically perturbated subjects. The abnormal behaviors were yawning, retrocollis, hyperactivity, hypersensitivity, "beating drum" behavior, squealing, head bobbing, circling, sniffing, abnormal posturing, and facial twitching. Shifts in the power frequency spectra of the discharge patterns were noted between quiet and pacing behavioral states. Hypersensitivity to various auditory, tactile, and visual stimulation was present and shifts in the brainstem ambient power spectral frequency occurred in response to tactile stimulation. These findings suggest that the brainstem generates and propagates pathological discharges that can be elicited by mechanical and DC electrical perturbation. Cocaine was found to activate the discharge system and thus induce abnormal behaviors that are generated at the discharge site and at distant sites to which the discharge propagates. Cognitive functions may also be involved since dopaminergic and serotonergic cellular elements at the brainstem level are also implicated.     

从中国的社会转型看邪教在当代社会的生存条件

当代中国的社会转型主要包括三个层面,即经济体制的转轨、社会结构的变动和社会形态的变迁。它们虽然有力地推动了我国经济、政治和文化的发展进步,但也不可避免地导致了新旧体制、意识形态和价值观念的激烈碰撞,从而为各种潜伏在人们心灵深处的封建迷信思想的沉渣泛起和境内外邪教组织的乘虚而入创造了条件。
