血管紧张素转换酶抑制剂与心肌缺血再灌注的细胞凋亡

随着心脏外科手术和介入治疗技术的进展以及心肌缺血患者的增加,心肌缺血再灌注损伤成为临床工作一种常见的病理生理过程。如何采用有效的治疗手段进行心肌保护,防治或降低缺血再灌注所造成的损伤,一直是心脏科学探索的一个重要课题。血管紧张素转化酶抑制剂对很多心脏疾病的治疗特别是拟行心脏手术患者的治疗都取得了良好的效果。随着对其研究的进展,其预处理可为临床预防治疗心肌缺血再灌注损伤提供思路与方法。

Is personal growth initiative associated with later life satisfaction in Chinese college students? A 15‐week prospective analysis

Personal growth initiative (PGI) is presumed to foster positive change leading to positive psychological adjustment. Accordingly, in this study we examined PGI as a predictor of life satisfaction 15 weeks later in a sample of 152 Chinese college students. Time 1 PGI was found to explain a significant amount of unique variance in Time 2 life satisfaction, even after controlling for Time 1 life satisfaction and Time 2 PGI. Specifically, (lower) intentional behavior and planfulness at baseline emerged as significant predictors of later life satisfaction. No evidence was found indicating that life satisfaction at Time 1 accounted for any significant amount of unique variance in PGI processes at Time 2, after controlling for baseline PGI processes and concurrent life satisfaction. Overall, the present findings are the first to demonstrate the importance of PGI as a prospective predictor of positive psychological adjustment in adults.     

精神分裂症患者的语音感知

精神分裂症是一种常见的精神疾病, 表现为多方面的症状, 其中, 语言异常是精神分裂症患者认知损伤的核心症状之一。本文关注精神分裂症患者的语音感知, 从音段和超音段两方面简述国内外对精神分裂症患者语音感知开展的行为和神经科学实验, 指出中国应加大对中国精神分裂症患者的汉语语音感知探索。     

阶层流动的“双刃剑”效应及其心理机制

阶层流动是指人们在社会分层体系中相对位置的变化。人们普遍预期,向上流动促进个体发展和社会进步。然而近期研究也表明,向上流动还可能损害个体健康和主观幸福感,使人们低估和容忍社会不平等,并反对再分配。地位认同、贫富归因倾向以及系统公正信念能够解释向上流动的双刃剑效应。未来研究需要进一步澄清向上流动感知的具体表现,深入考察向上流动影响的心理机制,探索促进阶层流动积极效应发挥的干预方法。     

Lower class people suffered more (but perceived fewer risk disadvantages) during the COVID-19 pandemic

Does COVID-19 affect people of all classes equally? In the current research, we focus on the social issue of risk inequality during the early stages of the COVID-19 pandemic. Using a nationwide survey conducted in China (N = 1,137), we predicted and found that compared to higher-class individuals, lower-class participants reported a stronger decline in self-rated health as well as economic well-being due to the COVID-19 outbreak. At the same time, we examined participants' beliefs regarding the distribution of risks. The results demonstrated that although lower-class individuals were facing higher risks, they expressed lesser belief in such a risk inequality than their higher-class counterparts. This tendency was partly mediated by their stronger endorsement of system-justifying beliefs. The findings provide novel evidence of the misperception of risk inequality among the disadvantaged in the context of COVID-19. Implications for science and policy are discussed.     

A 32-society investigation of the influence of perceived economic inequality on social class stereotyping

There is a growing body of work suggesting that social class stereotypes are amplified when people perceive higher levels of economic inequality—that is, the wealthy are perceived as more competent and assertive and the poor as more incompetent and unassertive. The present study tested this prediction in 32 societies and also examines the role of wealth-based categorization in explaining this relationship. We found that people who perceived higher economic inequality were indeed more likely to consider wealth as a meaningful basis for categorization. Unexpectedly, however, higher levels of perceived inequality were associated with perceiving the wealthy as less competent and assertive and the poor as more competent and assertive. Unpacking this further, exploratory analyses showed that the observed tendency to stereotype the wealthy negatively only emerged in societies with lower social mobility and democracy and higher corruption. This points to the importance of understanding how socio-structural features that co-occur with economic inequality may shape perceptions of the wealthy and the poor.     

Political distrust,perceived threat,and intentions to engage in normative and violent collective action: A mixed-methods study

In three studies, we examined the role of distrust and perceived threat in intentions to engage in normative and violent non-normative collective action. A field-based qualitative study of 35 pro-democracy protestors during the 2019 Hong Kong Anti-Extradition protests revealed that perceived threat to Hong Kong values alongside distrust of political institutions spurred collective action engagement and support for defensive violent collection action. In Study 2, a questionnaire (N = 639) testing pro-democracy action intentions demonstrated direct paths on both normative and violent collective action intentions from distrust and threat. In Study 3 (N = 133), experimental trust and threat manipulations demonstrated a significant association between distrust and threat on violent collective action intentions and acceptance, and a significant interaction on acceptance of violent collective action. Our results reveal the importance of distrust and threat in attitudinal support for, and engagement in, collective action and their role in transitioning from non-violent to violent collective action.     

Internalization of the model minority myth and sociodemographic factors shaping Asians/Asian Americans' experiences of discrimination during COVID-19

Despite appearing positive, the model minority myth (MMM), or the perception that Asian Americans are “problem-free” minorities, maintains unfair racial hierarchies and discredits the pervasiveness of systemic racism faced by Asian Americans and other Black, Indigenous, and people of Color. This study investigated the role of internalized MMM in Asian/Asian Americans' (A/AA) experiences during the syndemic of COVID-19 and our society's racial reckoning. Using a mixed methods approach, we analyzed A/AA college students' open-ended responses to a query about their experiences as A/AA during COVID-19, which resulted in qualitative themes of Personal and Vicarious Discrimination, Vigilance, Safety due to Ethnicity, Safety due to Environment, and No Difference during COVID-19. We then conducted a series of logistic and linear regression models to examine how internalized MMM and sociodemographic factors (i.e., ethnic group, gender, and generational status) were associated with qualitative themes and quantitative measures of COVID-related discrimination. Overall, findings demonstrated that greater internalized MMM, as well as identifying as South Asian, male, and an international/first-generation immigrant student, were linked to fewer qualitative and quantitative reports of vicarious discrimination. We conclude with implications for research and practice in community psychology that further examine the racialized experiences among A/AA college students and ultimately seek to challenge the MMM and racial hierarchies perpetuating systems of oppression.
