压力对“蚁族”群体心理健康的影响:希望的调节作用

以广州市棠下、上社、岑村、赤沙等地340名"蚁族"(高校毕业生低收入聚居群体)为被试,采用成人希望特质量表(ADHS)、压力知觉量表(CPSS)、一般心理健康问卷(GHQ),考察了"蚁族"群体的希望水平,并分析了希望在压力和心理健康之间的调节作用。结果发现:①从整体上看,该群体的希望处于中等偏上水平。②压力对于心理健康水平有显著的负向影响;希望能够起到压力缓冲作用,调节压力与一般健康问题、忧郁情绪和自我肯定感之间的关系。③希望对心理健康的忧郁、自我肯定维度的调节作用大小不同,对于忧郁情绪的调节作用更大,而对自我肯定调节作用较小。     

高龄患者心脏手术围术期处理要点

随着高龄心脏病患者日益增多,不断总结高龄患者心脏手术围术期处理经验,是我国心脏外科的一个重要课题。虽然,高龄患者心脏手术非致命性并发症发生率、住院时间长、手术死亡率高,但手术后将近2／3的患者生存超过5个年头,完全摆脱了心脏疾病的症状,没有了心脏疾患的束缚和限制,享受着手术后的独立的舒适生活。高龄患者进行心脏手术是可行...     

宫腔镜发展和应用的哲学思考

宫腔镜技术是现代妇科微创技术,宫腔镜技术的产生和发展是技术目的和技术手段矛盾发展的结果,宫腔镜技术的具体应用过程体现了马克思主义哲学原理的作用。以马克思主义哲学为指导,可使我们在对待宫腔镜应用中的具体问题时,高瞻远瞩,安全、有效地对患者实施诊治,同时,提高自己的综合素质。     

医务人员对艾滋病人态度及其相关因素分析——以北京两所综合医院为例

为了解医务人员对艾滋病人及病毒携带者的态度,选取北京市两所三级甲等医院392名医务人员进行自填式问卷调查.结果显示,医务人员对艾滋病感染者及病人的歧视严重,同时医务人员对经性途径感染患者的歧视高于其它途径感染患者,也高于乙肝或梅毒病人.道德化评价和对于艾滋病的认识有限是产生艾滋病相关羞辱和歧视的重要原因.     

从《周易参同契》看易学在道教中的传播与影响

<周易参同契>作为道教易学的重要代表作,其最重要的特色是会归"大易"、"黄老"和"炉火"三家之理,借<周易>言黄老说炼丹.本文将<周易参同契>置于汉代易学的背景下,从黄老道家哲学与道教仙学的发展中,来探讨<周易参同契>如何托<周易>卦爻象为象征符号来隐喻金丹道之内涵,以展示易学在道教中的传播与影响.     

“拟议”“变化”与文学复古

何景明与李梦阳论诗,曾引《周易·系辞》中的“拟议以成其变化”来针砭对方的“尺寸法古”.后来李攀龙将这一易学命题提升为诗文复古的纲领,既标志着复古理论的“成熟”,也标志着复古实践陷入窘境.通过探讨宋明学者如何阐释这一易学命题,可以发现复古论者的思维方式深受经学影响;通过解析复古论者如何运用这一易学命题,可以透视李、何论诗的分歧所在,以及前后七子复古思想的变化.     

大学生的自我差异与价值偏好

基于以往对自我透视和价值偏好的研究,本研究提出自我差异是引发价值偏好出现分离的原因之一。两项研究对这一假设进行了检验。结果发现：相对于害怕的可能自我,大学生在期望可能自我上体验到更大的差异;在可能自我差异激活后,理想主义价值在个体的价值系统中占据主导地位,而在当前自我差异激活后,实用主义价值占据主导地位;当下目标和当前自我同时启动时,与当下目标未启动时,两组个体对价值偏好无显著差异。     

“国粹”与“国魂”——弘扬中华伦理价值 重铸民族精神

在中华民族文化出现复兴曙光之际,我们在当代文化建设中一定要努力弘扬中华文化。中华文化对世界的独特贡献就在于它崇尚道德的精神,这是中华文化的真正"国粹"。当前文化建设的核心是重新反思我们近百年来受到的西方价值观的影响,着力弘扬中华文化的群体和他人价值导向、义以为上的道义追求、义务为本的责任意识、等差礼让的人际伦理、人心自律的主体精神,只有重新弘扬中华文化的这些核心价值观,才会为民族唤回灵魂,才会为国家发展提供强大的动力和凝聚力,才会为社会提供强有力的粘合剂和调和液,真正重塑起我们的民族精神和国家精神。     

Ursolic acid attenuates lipopolysaccharide-induced cognitive deficits in mouse brain through suppressing p38/NF-κB mediated inflammatory pathways

Evidence indicates that systemic administration of lipopolysaccharide (LPS) induces brain inflammation, ultimately resulting in cognitive deficits. Ursolic acid (UA), a plant-derived pentacyclic triterpenoid, is well known to possess multiple biological functions, including antioxidant, anti-tumor and anti-inflammatory activities. In the present study, we assessed the protective effect of UA against the LPS-induced cognitive deficits in mice. We found that UA significantly improved cognitive deficits of LPS-treated mice in open field, step-through passive avoidance and Morris water maze tasks. One potential mechanism of this action was attributed to the decreased production of pro-inflammatory markers including COX-2, iNOS, TNF-α, IL-1β, IL-2 and IL-6 in LPS-treated mouse brain. Mechanistically, UA markedly inhibited LPS-induced IκBα phosphorylation and degradation, NF-κB p65 nuclear translocation and p38 activation in mouse brain, but did not affect the activation of TLR4, MyD88, ERK, JNK and Akt. Taken together, these results suggest that UA may be useful for mitigating inflammation-associated brain disorders by inhibiting pro-inflammatory factors production, at least in part, through blocking the p38/NF-κB signaling pathways.     

Perceptions of parent-adolescent communication within families: it is a matter of perspective

This study examined the concordance between parental and youth's perceptions regarding open communication in their families and its association with youth's psychosocial adjustment. The relative importance of parental and adolescents' perceptions of open family communication in relation to youth's psychosocial adjustment was also investigated. Participants were 336 parent-youth dyads from inner-city low-income communities in an eastern city in the United States. Both parental and youth's perceptions of open communication in the family were categorized into "high" and "low" groups using a median split in scores. Four parent-youth concordance groups (i.e. high-high, high-low, low-high and low-low) were derived based on the combination of the levels of parental and youth's perceptions. Parental and youth's perceptions about open communication were modestly correlated (r = 0.129, p < 0.05). The level of concordance differed by youth gender with male adolescents and their parents being more likely to perceive lower levels of open communication (i.e. "low-low") than females and their parents (32% versus 19%, p < 0.05). In general, youth demonstrated poorer psychosocial adjustment if they perceived a lower level of open communication between them and their parents, independent of the level of their parents' perceptions (e.g. "high" or "low"). The findings suggest an important role of adolescents' own perceptions of the openness of the family communication in relation to adolescent psychosocial adjustment. Developmentally and gender appropriate intervention programs are needed to improve the openness of parent-adolescent communication, to help both parents and youth to recognize the significant preventive role of open communication in the family, especially, the socioeconomically disadvantaged families.
