基于中国家庭追踪调查库(CFPS)2010—2018年数据,采用面板计量模型和中介效应模型,研究房价对城镇居民消费不平等的影响效应及作用机制。结果表明:房价会正向影响城镇居民消费不平等,运用工具变量法进行内生性检验以及其他稳健性检验后,以上结论稳健。机制检验结果表明,房价会通过家庭人均消费支出影响城镇居民消费不平等,房价对居住支出和教育文化娱乐支出的影响程度较大,进一步说明房价上升会通过影响消费结构加剧城镇居民消费不平等。异质性检验结果表明,相对于城镇中低收入、中低金融资产家庭而言,房价变动对城镇高收入、高金融资产家庭居民消费的影响更明显。为此,应稳定房价、合理引导住房支出和调整居民消费结构,以促进消费公平,缩小消费不平等。

已有研究从文化的视角探究急/慢性应激的发生发展特点,为应激复原和创伤后应激障碍的干预提供了新的视角.自我构念是一个典型的文化影响自我定义方式的概念,是一种体现在个人层面的稳定的文化特征,然而自我构念是否以及如何影响个体的应激反应,还未有系统的总结与探讨.通过回顾已有实证性研究,发现在集体主义文化下互依自我构念个体表现出快反应快恢复的急性应激反应模式;在个人主义文化下高互依自我构念和低独立自我构念个体的慢性应激水平更高.这些结果表明,与主流文化背景一致的自我构念促进个体的应激适应性.然而,这些有限的证据仅是从文化的视角理解急/慢性应激反应和创伤后应激障碍的冰山一角,未来研究需要结合主流文化背景探讨自我构念的作用,并且将自我构念纳入创伤后应激障碍的诊疗和干预框架.

Steroidogenesis from cholesterol in placental trophoblasts is fundamentally involved in the establishment and maintenance of *** transcription factor gene heart and neural crest derivatives expressed1(Hand1)promotes differentiation of mouse trophoblast giant ***,the role of HAND1 in human trophoblasts remains ***,we report that HAND1 inhibits human trophoblastic progesterone(P4)and estradiol(E2)from cholesterol through downregulation of the expression of steroidogenic enzymes,including aromatase,P450 cholesterol side-chain cleavage enzyme(P450 scc),and 3β-hydroxysteroid dehydrogenase type 1(3β-HSD1).Mechanically,although HAND1 inhibits transcription of aromatase by directly binding to aromatase gene promoter,it restrains transcription of P450 scc by upregulation of the methylation status of P450 scc gene promoter through its binding to ALKBH1,a *** aromatase and P450 scc,HAND1 decreases 3β-HSD1 m RNA levels by the reduction of its RNA stability through binding to and subsequent destabilizing protein Hu ***,HAND1 suppresses circulating P4 and E2 levels derived from JEG-3 xenograft and attenuates uterine response to P4 and ***,our results uncover a hitherto uncharacterized role of HAND1 in the regulation of cholesterol metabolism in human trophoblasts,which may help pinpoint the underlying mechanisms involved in supporting the development and physiological function of the human placenta.
