女人为吃每周撒谎九次英国一项调查显示,女性为"吃"平均每年撒谎474次,相当于每周9次。她们常在吃过什么、吃了多少、喝过多少酒等问题上遮遮掩掩、谎话连篇。研究人员调查约3000名英国女性后发现,她们最常说的谎话是在大快朵颐后说:"这没多少。"另外,女性明明清楚自己管不住嘴,仍会坚持说"我午饭吃太多了,饭后不会再吃东西"。排位第三的谎言是"我很少吃这个",实际上她们常常吃。当你听到女性说"我没有碰过这些饼干"时,她可能刚吞下去五块;她们说"只喝

当怨恨变成思念

"在这个世界上,给予我生命的两个人,已经有一个永远离开了我。您走了,留下我在这复杂的人世间,不知道明天还有什么危险,您甚至忘了告诉我该怎样成长。许多的言语无处倾诉,许多的感伤无从表达,许多的委屈要独自吞咽,许多的努力也失去了意义。树欲静而风不止,子欲养而亲不在,世界上最疼我的那个人去了……"这是笔者在参与一项"哀伤咨询"课题时,为招募参与者写的海报语。灵感来源于著名作家张洁的同名小说,那本书是张洁对母亲去世最沉重的悼念。一个人不管多大,母亲去世的那一天注定会成为生命里最灰暗的一天。那一

Emotional Consequence of Telling a Lie

Generally, arousal increases when telling a lie, as indicated in psychophysiological studies about lie detection. But the emotional valence induced by lying is unknown, though intuition indicates that it may be negative. Indeed, the EDA （electrodermal activity）, used in such studies, only shows arousal changes during an emotional response. In this study, we used two tasks in order to examine the emotional valence induced by lying. At the beginning, in the deceptive task, participants answered ＂no＂ to every question regarding the nature of displayed playing cards. Therefore, they told a lie about specific cards. Their EDA was recorded all along the task. Secondly, in the figure estimation task, they assessed pictures positively or negatively after looking at playing cards visibly or subliminally as prime stimuli. We expected them to tend to estimate figures negatively when cards relevant to deception had been previously shown. This would mean that an affective priming effect due to telling a lie actually occurred. All in all, this effect was found only when prime stimuli had been displayed visibly. This result suggests that lying per se induces negative emotions even without motivation or punishment due to lying. Furthermore, we found that such effect was all the more obvious in participants whose EDA changes were salient while lying.     

户外探险旅游——约上“驴友”野外远足

户外探险旅游最早可追溯到古代的游牧民族迁徙,或僧侣们讲经布道的长途跋涉等。发展到今天,它囊括了登山、探险、攀岩、露营、漂流、四驱越野、滑雪、徒步、自行车、穿越等等。近年来,更多的人,包括许多中老年人,开始喜欢这种回归自然的旅游方式,约上几位"驴友",做一次野外远足探险,不仅为了锻炼身体,也为了挑战自我。     

Heart:降压药物对长期血压的影响

日本科学家研究老人睡眠不足易发心脏病

日本科学家最新研究表明,如果老年人每晚睡眠时间不足7.5h,心脏病发作概率最高增加3倍。日本自治医科大学博士江口一雄(音译)和同事对1255名33岁至97岁的参与者进行了为期23个月的跟踪     

基于个体参与者数据Meta分析评价临床药师会诊在感染性疾病治疗中的效果研究

目的 本研究旨在评估临床药师抗感染会诊的效果,探讨临床药师专业对会诊结局的影响。方法 本研究连续纳入2017年4月至2019年12月的感染会诊患者,前瞻性收集患者的基线信息,开展多中心队列研究。以临床医师在治疗中是否采纳临床药师的建议作为暴露因素,以感染治疗有效率作为结局指标。统计分析基于个体参与者数据(individual participant data,IPD)Meta分析。结果 共纳入来自12家三级医疗机构的2 631例感染会诊患者,IPD Meta分析结果显示,在控制其他混杂因素的情况下,临床药师会诊干预能改善患者的预后[合并比值比(OR)=1.80,95%置信区间(CI):1.14~2.84,P=0.012],而感染和非感染专业临床药师的会诊效果相当(OR=0.87,95%CI:0.62~1.22,P=0.421)。结论 临床药师会诊是一种能够优化感染性疾病治疗的干预措施,并且可实现服务的标准化。     

新发现

早饭前锻炼更健康?近日,科学家发现,早饭前锻炼能消耗2倍脂肪,长期坚持可更好地改善胰岛素敏感性,降低糖尿病和心脏病风险。这项研究中总共有30名参与者,全部都是男性,体重都处于超重或肥胖。这些人被分为三组。一组保持原来的生活习惯,不用做任何改变;另外两组,在研究人员的安排下增加了固定的运动项目,其中一组是先吃早饭,休息一段时间后锻炼,另外一组则是先锻炼再吃早饭。
