MAOA基因rs6323多态性与母亲支持性教养对青少年抑郁的交互作用：素质-压力假说与不同易感性假说的检验

抑郁的遗传与环境交互作用(G×E)机制已成为富有挑战性的前沿课题之一。然而,既有G×E研究大多关注遗传基因与不利环境的交互作用,相对忽视了积极环境的影响。本研究以1025名青少年为被试,运用问卷法与 DNA分型技术,采用间隔3年的追踪设计(T1小学六年级—T2初中三年级),考察 MAOA基因rs6323多态性与母亲支持性教养对青少年抑郁的交互作用以及性别在其中的调节作用,并同时采用新兴的探索性与验证性方法检验G×E交互作用的素质–压力假说与不同易感性假说。结果显示, MAOA基因rs6323多态性与母亲支持性教养行为交互作用于女青少年的抑郁,母亲支持性教养显著负向预测 GG 基因型女青少年的抑郁,但对 TT基因型女青少年抑郁的预测作用并不显著,该交互作用符合不同易感性假说。MAOA基因 rs6323多态性与母亲支持性教养对男青少年的抑郁无显著交互作用。本研究发现推进了抑郁遗传机制的研究,并为不同易感性假说提供新的研究证据。     

La satisfaction des attentes de soutien de l’apprenant : vers un examen nuancé de l’effet du soutien du supérieur immédiat sur le transfert des apprentissages

Supervisor support enhances transfer of training, but the process by which it operates is still unknown. One specific question remains about the distinction between expected and perceived support. This study aimed to assess the influence of expected and perceived support on transfer, as well as to examine the effect of a perception gap between these two types of support. Results obtained from 76 trainees indicate that: (1) both expected and perceived support foster transfer, (2) expected support explains a significant part of the variance of transfer in the presence of perceived support, (3) the gap between the two types of support help explain the effect of supervisor support on training transfer.     

脂联素基因多态性与原发性高血压研究进展

脂联素是脂肪细胞特异性细胞因子,与糖、脂代谢、胰岛素抵抗密切相关,具有抗炎、抗动脉粥样硬化特性。脂联素基因序列中存在相当数量的等位基因单核苷酸多态性（SNPs）,＋45T／G、＋164I／T和＋276G／TSNPs发生频率在原发性高血压（EH）中增高,直接影响脂联素血浆浓度。脂联素基因SNPs是EH的一个新易感因素。     

冠脉介入治疗时期氯吡格雷抵抗的认识与思考——抓住本质，全面获益

急性冠脉综合征已步入药物洗脱支架进行血运重建的时期,双联抗血小板治疗是接受PCI治疗的常规手段。临床发现部分患者不能从氯吡格雷治疗中获益,存在氯吡格雷抵抗的现象。笔者就氯吡格雷抵抗的发生机制、临床意义及治疗对策进行描述,反映相关研究的趋势和方向,为未来更优化抗血小板治疗提出一种策略。     

父母教养与MAOA基因rs6323多态性对学前儿童外化问题的共同作用

采用G×E交互作用的研究范式,以295名学前儿童（M=4.49）和其母亲、父亲作为研究对象,探讨母亲和父亲的教养方式与MAOA基因rs6323多态性对学前儿童外化问题行为的影响。结果发现：母亲、父亲教养方式和MAOA基因多态性对学前儿童外化问题行为的影响存在性别差异,预测男孩外化问题行为时,母亲和父亲教养方式的主效应显著,与MAOA基因多态性的交互作用不显著;在预测女孩外化问题行为时,父亲教养方式的主效应显著,母亲教养方式与MAOA基因多态性的交互作用显著,显著性区域分析发现,携带T等位基因的女孩更容易受到母亲消极教养的不利影响而产生更多外化问题行为,也更容易受到其积极教养的有利影响而减少外化问题行为,这一结果支持差别易感性理论模型。     

The Problem of a Transcendent God for the Well‐Being of Continuous Creation

This year marks the 30th Anniversary of Lynn White's critique of Christianity, which set off the field of eco‐theology. At that time, apologetic theologians responded to the White critique, that the Genesis “dominion” command is largely responsible for the contemporary ecological crisis, through reformulating Christian doctrines to address ecological issues. These pioneers have brought us a long way in terms of addressing both how Christianity has been responsible in supporting harmful human‐earth relations and what resources within the tradition might be useful for addressing the contemporary ecological crisis. Building on this work, this article suggests that Christian theology (whether eco or not) will continue to support an understanding of the human being as rooted “outside of creation” as long as the concept of a transcendent, Omni, Creator‐God is left intact. In place of this theological discourse of transcendence which secularizes the natural realm, I suggest a “radical materialist” (Val Plumwood) understanding of Christianity that moves between idealism and reductive materialism (both are forms of transcendence) through a “planetary” (Spivak) understanding of Creation and a “bio‐historical” (Gordon Kaufman) understanding of anthropology.     

The association between dopamine D4 receptor exon III polymorphism and intensity of PTSD symptoms among flood survivors

Abstract

Thanks to the development of molecular genetics methods it is now possible to look for the genes which may contribute to posttraumatic stress disorder (PTSD). Polymorphism located in exon III of dopamine receptor type 4 (DRD4) gene was related to maladaptive stress responses as well as temperament traits related to PTSD. This study analyzed the association between the variable number tandem repeat (VNTR) DRD4 exon III polymorphism and intensity of PTSD symptoms in 107 (57 women and 50 men) survivors of a flood aged 14–62. Intensity of PTSD symptoms was measured using PTSD-F and PTSD-C questionnaires. Multivariate analysis of covariance (MANCOVA) was conducted to test the main and interactive effects of genotype and level of trauma exposure. Participants with at least one copy of the DRD4 long allele (seven or eight repetitions) had more intense PTSD symptoms on the Avoidance/Numbing scale (Cohen's f = .22) and the Total Scale (Cohen's f = .2) of the PTSD-F than participants who did not have these alleles in genotype. The results must be treated with caution, however, due to methodological restrictions and they need to be replicated on a larger sample.     

DRD2基因TaqIA多态性与同伴侵害对青少年早期抑郁的交互作用

本研究运用问卷法与DNA分型技术,对1063名青少年(初次测评年龄为12.32±0.47岁,50.3%女生)进行间隔2年的追踪调查,考察DRD2基因TaqIA多态性与同伴身体侵害和关系侵害对青少年早期抑郁的交互作用及其性别差异。结果发现,TaqIA多态性与身体侵害、关系侵害均对男青少年抑郁存在显著的交互作用。在携带A2A2基因型的男生中,身体侵害和关系侵害可以显著正向预测其抑郁水平,而在携带A1等位基因的男生中,同伴侵害对抑郁无预测作用。此外,TaqIA多态性与身体侵害、关系侵害对女生抑郁均无显著交互作用。研究结果提示,同伴侵害是一种重要的候选环境指标,与TaqIA多态性交互影响青少年早期抑郁,并且性别在这一基因×环境交互作用中起到重要的调节效应。     

MAOA基因rs6323多态性与同伴关系对男青少年早期抑郁的影响

以683名男青少年为被试(初次测评时M = 13.35岁; SD = 0.51), 综合运用传统回归分析和新兴显著性区域检验, 考察了MAOA基因rs6323多态性与同伴关系对青少年早期抑郁的交互作用及其表现形式。结果表明：当同伴接纳水平较低时, G等位基因携带者的抑郁水平表现出高于T等位基因携带者的趋势, 当同伴接纳水平较高时, G型基因携带者的抑郁水平显著低于T等位基因携带者; 同伴接纳可以显著预测G等位基因携带者的抑郁, 但对T等位基因携带者的抑郁无显著预测作用; rs6323多态性与同伴拒绝的交互作用亦不显著。研究结果提示, 同伴关系对MAOA基因与男青少年早期抑郁的关联起调节作用, 且其作用形式部分支持不同易感性模型观点。
