超声内镜在诊治上消化道异位胰腺中的价值

异位胰腺是正常胰腺解剖部位以外的孤立胰腺组织,可发生在消化道或消化道外的许多部位。异位胰腺可以产生分泌各种胰酶和胰液,也可以发生急性、慢性胰腺炎甚至囊肿、肿瘤等正常的胰腺可发生的任何病变,并且通常难以通过病理学检查确诊。超声内镜提供了更准确的诊断异位胰腺的方法,对选择恰当的治疗措施有重要的指导作用。     

儿童大叶性肺炎诊治中的几点认识

大叶性肺炎是儿科呼吸系统常见、且较严重的疾病之一,与成年人大叶性肺炎差异较显著,近年来发病率在逐年升高,且婴幼儿患者明显增多,因起病隐匿,极易误诊、漏诊,病原学亦发生了较大的变迁,疗程较长,极大地威胁着儿童的身心健康,这就要求儿科医师有敏锐的洞察力、不循规蹈矩,运用哲学的辩证思维来分析病例,及时作相关检查,恰到好处地把握疗程。     

乙型肝炎病毒相关性肾炎抗病毒治疗进展

乙型肝炎病毒（HBV）相关性肾炎是与HBV感染相关的肾脏疾病,病理类型多为膜性肾病、膜增殖性肾小球肾炎等,临床表现常为肾病综合征或大量蛋白尿。由于发病机理尚不清楚,既往多采用激素等免疫抑制剂治疗,但临床效果不理想。由于该病和HBV感染有关,随着抗病毒药物治疗慢性乙型肝炎病毒感染取得较好疗效,已有研究应用干扰素、拉米夫定...

本文通过对涂阴肺结核及试验性治疗相关概念的分析探讨,结合临床实际,认为试验性治疗不仅有利于涂阴肺结核的早期诊断和及时治疗,也是减少误诊、漏诊的主要措施。     

2010年我国急性ST段抬高型心肌梗死诊断与治疗指南解读评析

近年来我国急性心肌梗死的发病率一直呈明显上升趋势,已接近国际平均水平。对于STEMI版早期诊断并及时开通梗死相关动脉、增加心肌再灌注、防止心肌进一步坏死,可显著降低心血管事件的发生。本文从STEMI的诊断、早期医疗、再灌注治疗、辅助治疗及二级预防等几个方面对2010年我国急性ST段抬高型心肌梗死的诊断与治疗指南进行了详细解读分析。     

What you cannot see can help you: the effect of exposure to unreportable stimuli on approach behavior

We examined effects of exposure to unreportable images of spiders on approach towards a tarantula. Pretests revealed awareness of the stimuli was at chance. Participants high or low (top and bottom 15%) on fear of spiders were randomly assigned to receive computer-generated exposure to unreportable pictures of spiders or outdoor scenes. They then engaged in a Behavioral Approach Task (BAT) with a live tarantula. Non-fearful participants completed more BAT items than spider-fearful individuals. Additionally, as predicted, a significant interaction (F(1,48)=5.12, p<.03) between fear of spiders and stimulus demonstrated that spider-fearful participants exposed to spiders completed more BAT items than spider-fearful participants exposed to control stimuli (but not as many as non-fearful participants). The findings support the hypothesis that exposure to unreportable feared stimuli promotes approach towards the feared object. Future research and clinical implications were discussed.     

Intertrial pellets influence the acquisition and expression of timed appetitive responding in rats

Two experiments examined temporally based changes in the conditioned magazine-entries of rats when a target food pellet arrived at a fixed time before the termination of a conditioned stimulus. Both experiments found that increasing the rate of intertrial pellets systematically interfered with the rate of acquisition. When intertrial pellets were featured in acquisition, their omission on test trials also resulted in a very poorly expressed conditioned response. On test trials preceded by intertrial pellets, however, peak times in groups trained with intertrial pellets were shifted in a rightward direction under a long but not short interstimulus interval. This rightward shift was accompanied by a smaller standard deviation. Our key findings are best accommodated by real-time associative models.     

Integrating information from two pictorial animations: Complexity and cognitive prerequisites influence performance

Dividing visual attention between spatially distinct sources of information could either be beneficial (if there is too much information for a single visualization) or detrimental (if interrelated information has to be mentally re‐integrated) for learning. We present a new display technology allowing for the presentation of two distinct animations by avoiding split foci of visual attention: learners are able to switch between animations by moving their head. We examined how 84 naïve learners integrated information in three presentation modes: the ‘vexing‐image’ mode displaying two animations, participants being able to switch between them without shifting the visual focus, a classical ‘split‐screen’ and an ‘overlaid’ condition. Results showed that reduced complexity led to higher performance. Further, we showed that participants with high mental rotation abilities were best in the ‘split‐screen’ mode, whereas participants with low mental rotation abilities benefited most from the ‘vexing‐image’. Theoretical and instructional consequences of these findings are discussed. Copyright © 2010 John Wiley & Sons, Ltd.
