Dopamine D1 receptors are responsible for stress-induced emotional memory deficit in mice

It is established that stress impairs spatial learning and memory via the hypothalamus-pituitary-adrenal axis response. Dopamine D1 receptors were also shown to be responsible for a stress-induced deficit of working memory. However, whether stress affects the subsequent emotional learning and memory is not elucidated yet. Here, we employed the well-established one-trial step-through task to study the effect of an acute psychological stress (induced by tail hanging for 5, 10, or 20?min) on emotional learning and memory, and the possible mechanisms as well. We demonstrated that tail hanging induced an obvious stress response. Either an acute tail-hanging stress or a single dose of intraperitoneally injected dopamine D1 receptor antagonist (SCH23390) significantly decreased the step-through latency in the one-trial step-through task. However, SCH23390 prevented the acute tail-hanging stress-induced decrease in the step-through latency. In addition, the effects of tail-hanging stress and/or SCH23390 on the changes in step-through latency were not through non-memory factors such as nociceptive perception and motor function. Our data indicate that the hyperactivation of dopamine D1 receptors mediated the stress-induced deficit of emotional learning and memory. This study may have clinical significance given that psychological stress is considered to play a role in susceptibility to some mental diseases such as depression and post-traumatic stress disorder.     

体外循环所致炎性肺损伤机制及保护进展

肺损伤是体外循环心内直视手术的主要并发症之一。肺损伤的机制十分复杂,主要是全身炎性反应和缺血/再灌注损伤所致。肺保护的方法多种多样,其目的是降低全身炎性反应,减轻或避免缺血/再灌注损伤。本文探讨体外循环肺损伤的机制和保护进展。     

循环肿瘤细胞的研究进展

循环肿瘤细胞（circulating tumor cells,CTCs）指自发或因诊疗操作由实体瘤或转移灶释放进入外周血循环的肿瘤细胞。CTCs能被看作液体活检,具有实时监测功能,是一种非侵入性的新型诊断工具,有助于早期发现肿瘤的微转移,可评估预后,在治疗的监测及个体化治疗上具有重要的临床意义。     

The Effects of Applicant Résumé Contents on Recruiters' Hiring Recommendations: The Mediating Roles of Recruiter Fit Perceptions

The résumé is the most commonly used selection tool for organisations. Past studies have demonstrated that recruiter hiring recommendations can be predicted based on the content of applicant résumés. However, the mechanisms underlying the links between résumé contents and hiring recommendations remain unclear. The present study extends previous research by examining the mediating roles of recruiters' multi‐faceted fit perceptions in a field setting. Data were collected from 216 organisational recruiters who participated in campus recruitment at seven universities in Taiwan. The results showed that applicant work experience and educational background increased recruiter hiring recommendations through recruiter perceived person–job (P–J) fit. In addition, applicant work experience predicted recruiter perceived person–organisation (P–O) fit, which in turn enhanced recruiter hiring recommendations.     

全球治理:公民社会与宗教发展

在全球化的进程当中,宗教发展已经很难“遁世”、“隐居”,更不可能独善其身。虽然现代化是推动全球化发展的重要力量,但在现代化之前,早已出现了全球化的基督宗教、伊斯兰教、佛教等跨国界发展。从治理的向度来说,宗教发展融合了国家、市场、社会的对立关系,重新创造性的结合国家、市场与社会,引导世界走向善治。而宗教组织要寻求全球性的发展甚至推动全球公民社会的实现,就有赖于跨国社会运动组织的发展。因此,如果20世纪的政治遗产是民族国家组成的世界体系,那么21世纪就是建构一个善治的全球公民社会。     

分散注意条件下前瞻记忆的完成水平及其影响因素初探

本研究试图探讨在分散注意条件下前瞻记忆的完成水平及其影响因素。被试为98名大学生。在实验中,当前任务为数字听写,同时放映一段无声动画短片,将前瞻记忆任务(即看到某一靶线索画面时在相应数字上做记号)嵌入其中,动画片结束后要求被试完成若干与动画片内容有关的问题(事先通过指导语告知)。结果发现：1、前瞻记忆任务的成绩与被试的性别几乎无关,与材料熟悉程度也无显著相关;2、与被试对材料的喜好程度显著相关,提示即使在分散注意条件下,被试在完成前瞻记忆任务时也可能会根据偏好自动调整注意的分配。     

浅析《太平经》中的"治国"思想

本文先引述了<太平经>的版本问题,进而简要分析了其成书时期、著者、思想来源以及其主要内容.在此基础上,提出了<太平经>中的"治国"所运用的"三"和"承负"两种思想,最后将其"治国"思想归结到君、臣、民"三合相通","立致太平"上.     

社会智力研究视角和方法的转变——从社会智力的测量观到人格的社会智力观

在社会智力研究的早期,研究者们运用测量观的视角和方法对社会智力进行了研究,取得了不少的成果。但是随着研究的进行,传统测量观的发展却遇到了极大的困难,如不能对社会智力和学业智力进行有效的区分等。人格的社会智力观强调社会行为的背景具体化和行为的主观意义,主张探询人的一般化的社会认知机制,为社会智力的研究展开了一个新的视角。     

数学文化与儿童数学认知

数学文化以文化为视角.在人类文化发展的历史过程中审视和理解数学,为我们认识和理解儿童数学认知开辟了全新的方向.作为数学文化的重要内容的数学信念、数学价值观、数学典故、数学符号、数学法则以及实物工具等,在儿童数学认知的知识提取、理解与表征、记忆与策略、认知风格、情绪态度以及自我效能等方面起着重要的影响作用.
