腹腔镜下胃转流术治疗2型糖尿病的疗效分析及可行性研究

胃转流术治疗重度肥胖由来已久.近年来,国内研究通过接受胃转流术的肥胖患者的长期随访后发现,胃转流术可长期、稳定的缓解2型糖尿病,并能减少糖尿病并发症,为2型糖尿病的外科治疗开辟了新途径.本文总结我院32例接受腹腔镜胃转流术的2型糖尿病患者术后随访情况,分析后认为腹腔镜下胃转流术治疗2型糖尿病疗效显著,具有微创、安全、有效的特点,是2型糖尿病治疗方法的一种补充和完善,值得临床推广.     

Convergent Thinking Moderates the Relationship between Divergent Thinking and Scientific Creativity

Creativity plays an important role in human society as well as in individual development, and creativity in the domain of science is a specific form. A body of research had demonstrated the role of divergent thinking in creativity. The role of convergent thinking had also been recognized, but more empirical evidence was needed. To investigate the interaction between convergent and divergent thinking on adolescent scientific creativity, the current study tested 588 high school students. The results showed that convergent thinking interacted with fluency/flexibility of divergent thinking on scientific creativity. In particular, divergent thinking predicted creativity in those high in convergent thinking. Findings suggested a threshold-setting effect of convergent thinking, which meant only when convergent thinking capacity reached a certain level, divergent thinking could play a role in scientific creativity. Implications for future research and educational practice were discussed.     

社会自我效能感的结构、测量及其作用机制

班杜拉的自我效能理论一直是当代心理学的热点话题。作为社交情境中的特殊自我效能感,社会自我效能感是能够影响个人人际互动质量的重要心理因素之一,因此也逐渐开始受到研究者的关注。通过对国内外理论文章与实证研究的分析发现,社会自我效能感与社交自尊、社交果敢性、社交信心等相关概念有所不同,是指个体对自己社交能力的主观信念;其内涵在不同文化自我或情境的视角下可能存在差异,具有多元结构的可能性。社会自我效能感与个人特质、情绪、态度及行为等变量相关,并能够显著预测抑郁、社交焦虑、生活满意度、社会适应等变量。此外,社会自我效能感也在外向、性别角色、依恋、目标定向、网络人际交往的影响机制中起到中介作用,且能够对压力和不公平感所造成的消极影响具有一定的缓冲作用。然而有关研究仍存在诸多问题与不足,未来研究应该关注社会自我效能感内涵与结构的确定、测量工具的开发,并加强对其影响因素与影响效应的探索、系统模型的构建和跨文化研究的扩展。     

“I Am My Own Gender”: Resilience Strategies of Trans Youth

Nineteen trans youth participated in a phenomenological study of their resilience strategies for navigating stressors in their lives. The authors identified 5 supports and 6 threats to participants’ resilience. The 5 themes of resilience were: (a) ability to self‐define and theorize one's gender, (b) proactive agency and access to supportive educational systems, (c) connection to a trans‐affirming community, (d) reframing of mental health challenges, and (e) navigation of relationships with family and friends. The 6 major threats to participants’ resilience were: (a) experiences of adultism, (b) health care access challenges, (c) emotional and social isolation, (d) employment discrimination, (e) limited access to financial resources, and (f) gender policing.     

扁鹊取意“病却”考

扁鹊是中国医学史上的一个重要名人。人们对扁鹊的认识多来源于《史记·扁鹊传》,篇中撰写的主人公有实有虚,即扁鹊可以指称具体的某一位医生,亦可泛称众良医。在汉画像石中,扁鹊形象奇特,人面鹊身,是一个抽象化的人物。解读两种文献材料,扁鹊应该为古代良医之公名,而非确指某个固定的人。扁鹊一名的内涵,因声求义,扁鹊与“病却”古音相似,此名当取义于“病却”,以此寓神医之德,寄托病人的心愿。把神医命名为“病却”既合人们的愿望,又合古人命名的法则。

Temporal Discounting Mechanisms of Future‐oriented Coping: Evidence from Delay Discounting and Task Prioritization Paradigms

Four studies were conducted to examine the relationship between future‐oriented coping and temporal discounting under different situational conditions. In Study 1, 138 participants were primed with either stressful or neutral stimuli, followed by a delay‐discounting task. In Study 2, 118 participants were primed with either stressful or neutral stimuli, followed by a task‐prioritization activity. The results of both studies indicated that future‐oriented coping had a significant negative association with temporal discounting or the number of rational choices in the neutral‐priming condition, but the relationship was not significant in the stress‐priming condition. In Study 3, qualitative data revealed that the major reason for shifting choices from larger but later payoffs to smaller but sooner rewards in a stressful condition was to reduce the stressful mood, create a positive mood, and promote a sense of accomplishment. This explanation was corroborated by Study 4, in which one group was allowed to choose an immediate payoff and the other group was blocked from choosing that immediate payoff. We confirmed that post‐test anxiety was significantly lower in the immediate payoff group compared with the delayed‐payoff group in proactive and preventive coping, using pre‐test anxiety as a covariate. Preventive coping helped to reduce anxiety levels in a stressful condition only when there was a choice to obtain an immediate payoff. These findings underscore the relationship between future‐oriented coping and temporal discounting, as well as the flexibility of discounting in the face of stress.

同伴侵害与人际关系取向人格特质的交叉滞后分析:城市原住儿童与农村随迁儿童的比较

研究采用间隔两年的追踪设计,分析了477名农村随迁儿童（男生57.10%;2014年时平均年龄为11.54±0.64岁）与245名城市原住儿童（男生50.60%;2014年时平均年龄为11.36±0.51岁）的同伴侵害与和谐性、人际触觉两个人际关系取向人格维度的相互影响。这些儿童分别来自上海市采取融合教育的四所公立初中。他们首次参加本研究时为初中预备年级。交叉滞后分析表明,（1）在原住儿童组,时间1的同伴侵害可以负向预测时间2的和谐性与人际触觉;（2）在随迁儿童组,和谐性与同伴侵害有负向循环作用关系,且时间1的同伴侵害可以负向预测时间2的人际触觉。研究一定程度上揭示了人际人格发展与所处环境（特别是同伴侵害的不利环境）的动态相互作用模式。文章最后讨论了原住儿童与随迁儿童混合编班的融合教育模式对所有城市儿童适应社会转型的现实意义。     

Exposure to nature counteracts aggression after depletion

Acts of self‐control are more likely to fail after previous exertion of self‐control, known as the ego depletion effect. Research has shown that depleted participants behave more aggressively than non‐depleted participants, especially after being provoked. Although exposure to nature (e.g., a walk in the park) has been predicted to replenish resources common to executive functioning and self‐control, the extent to which exposure to nature may counteract the depletion effect on aggression has yet to be determined. The present study investigated the effects of exposure to nature on aggression following depletion. Aggression was measured by the intensity of noise blasts participants delivered to an ostensible opponent in a competition reaction‐time task. As predicted, an interaction occurred between depletion and environmental manipulations for provoked aggression. Specifically, depleted participants behaved more aggressively in response to provocation than non‐depleted participants in the urban condition. However, provoked aggression did not differ between depleted and non‐depleted participants in the natural condition. Moreover, within the depletion condition, participants in the natural condition had lower levels of provoked aggression than participants in the urban condition. This study suggests that a brief period of nature exposure may restore self‐control and help depleted people regain control over aggressive urges.
