研究尼可地尔、前列地尔及两药物联合应用预处理对心肌缺血再灌注中的影响,探究其作用机制.采用Tunel法检测心肌组织的凋亡情况,免疫组化法检测Bax、Bcl-2和caspase-3的蛋白表达情况.结果显示尼可地尔和前列地尔半剂量联合组细胞凋亡数、Bax和caspase-3的表达量均明显低于其他给药组(P<0.05),Bcl-2的表达量明显高于其他给药组(P<0.05);尼可地尔和前列地尔单给药组细胞凋亡、Bax、caspase-3表达均有降低,Bcl-2表达升高,但效果不及联合用药半剂量组.以此得出结论尼可地尔和前列地尔的联合用药效果较好,可加强对心肌的保护作用. 相似文献

The use of parenting measures that are developed for use with Western families without testing their validity among families from non-Western cultural backgrounds may not be appropriate. Similar parenting behaviors may affect child outcomes in different ways across different cultures. This study examined the cross-cultural validity of an observational Maternal Responsiveness coding system and of self-reports of lax/inconsistent parenting in Euro–Canadian (n = 23) and East Asian immigrant mothers (n = 23) of 4- to 7-year-old sons. In Euro–Canadian mothers, observed parenting responsiveness was associated with less lax/inconsistent parenting and fewer child behavior problems. In East Asian immigrant mothers, however, observations of greater responsiveness were not related to reports of lax/inconsistent parenting, and were associated with greater child behavior problems. Implications for the use of these parenting measures across culture groups are discussed. 相似文献

Children raised in the profound deprivation associated with institutionalization are at elevated risk for negative outcomes
across a host of social and cognitive domains. This risk appears to be mitigated by early foster care or adoption into a family
setting. Although pervasive developmental problems have been noted in a substantial proportion of previously institutionalized
children, marked variation exists in the nature and severity of these deficits. Increasing evidence suggests that institutional
deprivation impacts the developing brain, potentially underlying the wide range of outcomes with which it is associated. In
the current review we examine the neural consequences of institutionalization and genetic factors associated with differences
in outcome in an effort to characterize the consequences of early deprivation at a neurobiological level. Although the effects
of institutional deprivation have been studied for more than 50 years much remains unanswered regarding the pathways through
which institutionalization impacts child development. Through a more complete and nuanced assessment of the neural correlates
of exposure and recovery as well as a better understanding of the individual factors involved we will be better able to delineate
the impact of early adversity in the setting of severe social deprivation. 相似文献

We compared working memory (WM) for the location of social versus non-social targets in infant siblings of children with Autism Spectrum Disorders (sibs-ASD, n = 25) and of typically developing children (sibs-TD, n = 30) at 6.5 and 9 months of age. There was a significant interaction of risk group and target type on WM, in which the sibs-ASD had better WM for non-social targets as compared with controls. There was no group by stimulus interaction on two non-memory measures. The results suggest that the increased competency of sibs-ASD in WM (creating, updating and using transient representations) for non-social stimuli distinguishes them from sibs-TD by 9 months of age. This early emerging strength is discussed as a developmental pathway that may have implications for social attention and learning in children at risk for ASD. 相似文献

This article uses the Theory of Gender and Power to examine women's vulnerability to HIV/AIDS in order to: understand the vulnerability of female sex workers/poor women due to poverty and lack of educational resources; explore women's vulnerability in the context of client/partner violence, alcohol use, male partner's high-risk behaviors, and women's lack of control in their intimate relationships; and explore the role of traditional heterosexual gender norms in the outcomes of sexual negotiation. Ethnographic data were collected from 32 women and 38 men in India as part of an ongoing National Institute of Mental Health study. Results highlighted women's vulnerability to HIV/AIDS stemming from partner violence, alcohol use, poverty, dangers of sex work environments, and tacit acceptance of cultural/gender norms. 相似文献

In 2007, the Association of Psychologists in Academic Health Centers (APAHC), formerly known as Association of Medical School
Psychologists (AMSP), held its first national conference since 1997. At the latter conference, the author of this article
[Sheridan (1999) Journal of Clinical Psychology in Medical Settings, 6, 211–218] was asked to present some of the issues that would be important to health care psychologists in the next decade.
These issues included the role of psychology in academic health centers, interventions psychologists offer, reimbursements
for such treatments, education and training models, and research. This article examines those observations, offers new data,
and explores the current challenges and opportunities for psychologists in academic health centers. The presentation also
addresses aspirations of psychologists as well as resistances within the profession.
Parts of this paper were delivered at the 3rd Conference of the Association of Academic Health Center Psychologists in Minneapolis,
Minnesota in 2007. 相似文献

Although the emotion regulation strategy of reappraisal has been associated with adaptive outcomes, there is a growing evidence that it may not be adaptive in all contexts. In the present study, adolescents reported their use of habitual reappraisal and their experiences with peer victimisation, a chronic stressor that is associated with reduced well-being in this population. We examined how these variables predicted physiological reactivity (vagal withdrawal and changes in pre-ejection period) during a social stressor (i.e., Trier Social Stress Task). In line with previous research, at high levels of victimisation, habitual reappraisal predicted adaptive physiological reactivity (i.e., greater vagal withdrawal). Conversely, at low levels of victimisation, habitual reappraisal predicted maladaptive physiological reactivity (i.e., blunted vagal withdrawal). These findings were specific to parasympathetic reactivity. They suggest that habitual reappraisal may exert different effects on parasympathetic reactivity depending on the presence of stressors, and highlight the importance of examining the role of contextual factors in determining the adaptiveness of emotion regulation strategies. 相似文献

A growing body of research suggests that impulsive responses to emotion more robustly predict suicidality than do other forms of impulsivity. This issue has not yet been examined within bipolar disorder, however. Participants diagnosed with bipolar I disorder (n = 133) and control participants (n = 110) diagnosed with no mood or psychotic disorder completed self‐report measures of emotion‐triggered impulsivity (Negative and Positive Urgency Scales) and interviews concerning lifetime suicidality. Analyses examined the effects of emotion‐triggered impulsivity alone and in combination with gender, age of onset, depression severity, comorbid anxiety, comorbid substance use, and medication. A history of suicide ideation and attempts, as well as self‐harm, were significantly more common in the bipolar disorder group compared with the control group. Impulsive responses to positive emotions related to suicide ideation, attempts, and self‐harm within the bipolar group. Findings extend research on the importance of emotion‐triggered impulsivity to a broad range of key outcomes within bipolar disorder. The discussion focuses on limitations and potential clinical implications. 相似文献

Utilizing complex statistical analyses, namely latent growth modeling, the long-term development of worries among peace movement supporters is examined. Data originate from a 7-wave German longitudinal study started in 1985 with the then on average 14-year-old subjects. Waves were interspersed at 3? year intervals. Activists are assumed to have lower (self-related) microworries (H1) and higher macroworries (concerned with larger entities; H2) than non-activists at the onset of the study. Non-activists who appraised the threat of nuclear war as high in 1985 are assumed to report worse mental health than their activist age mates 21 years later (H3). Activists are assumed to express relatively more macroworries than non-activists in mid-adulthood (H4). All four hypotheses were confirmed. Results are interpreted as evidence for the psychoanalytic argumentation by Leith?user that fear of global threats is likely to be displaced into personal anxiety if not coped with in the form of ??identifying participation?? in political action, suggesting that refraining from acting out against a perceived sociopolitical threat is a long-term risk for a positive mental-health trajectory. 相似文献
