Expressed Emotion In The Narrative Context of Family Photographs

This study aims to elucidate cognitive and contextual aspects of the EE (Expressed Emotion) concept. The EE levels of both parents of two first admission psychotic patients were rated from the Five Minute Speech Sample (FMSS), and the emotional responses were further analyzed in narratives of family photographs. The attribution model was found to provide an explanatory framework for understanding relatives' expressed emotions (EE) toward a family member suffering from psychotic disturbances. Four case reports indicated that family photographs induced parents to create narratives in which emotions, attributions, and strategies for coping with stressful aspects of the illness came forward as intertwined phenomena. The method can offer more comprehensive data for intervention strategies aiming to alter the prevailing atmosphere and interaction patterns within the high EE family.     

The Experience of Time in Acute Psychosis and Schizophrenia

From the narrative point of view the plot of a story configures time. In psychosis, when experiences remain unnarrated, experience being-in-time is also missing. Once experiences are given narrative form, they can be left behind as a part of individual's personal history, thus enabling present experiences to be narrated. Unnarrated experiences do not accumulate. Narrative history contains, however, enough redundancy to invite you to restory your past in a new way if you need to. Hence, from the narrative point of view, early, family- and network-centered intervention is of special value in cases of acute psychosis.     

急性应激损伤错误监控与错误后调整

生活中,个体会时时关注自己的行为结果并及时做出调整以适应环境的变化。但在应激下个体能否有效地监控行为并做出适应性调整依然未知。本研究招募了52名男性大学生被试,将其随机分入应激组与控制组,采用特里尔社会应激测试(Trier Social Stress Test, TSST)诱发个体的应激反应,并结合错误意识任务(Error Awareness Task,EAT)探索个体急性应激下的错误监控与错误后调整过程。应激指标的结果显示应激组个体在应激任务后唾液皮质醇、心率、应激感知自我报告和负性情绪均显著高于控制组,表明急性应激的诱发是成功的。行为结果显示应激组的错误意识正确率显著低于控制组,错误意识反应时显著短于控制组;进一步地,应激组个体在意识到错误之后的试次上正确率显著低于未意识到错误之后的试次,并且应激组个体在意识到错误之后的试次上正确率低于控制组。结果表明急性应激降低了个体对错误反应的监控水平,即便在辨别出错误反应的情况下,个体的行为监控与调节也更差。本研究说明急性应激会损伤行为监控系统,导致个体的行为适应性下降。     

Differences in High and Low Anxiety Sensitive Women's Responses to a Laboratory‐Based Cold Pressor Task

Anxiety sensitivity (AS) has been linked to a variety of disabling chronic health conditions, including pain‐related conditions. A recent study has found that healthy women with high AS reported significantly higher levels of sensory and affective pain on an experimental cold pressor task compared to women with low AS. However, this study found no differences between AS groups for pain tolerance or pain threshold. In the present study, which was designed to replicate and extend these findings, 90 undergraduate university women were selected for inclusion in 1 of 2 AS groups (high or low) based on their screening scores on a 16‐item measure of AS. Participants were tested individually on a lab‐based cold pressor task using a variety of self‐report and observer‐measured variables. Data analyses revealed that, as expected, the high AS participants reported significantly more fear in response to the cold pressor on a relevant item of the McGill Pain Questionnaire – Short Form (SF‐MPQ) than did the low AS participants. Also as expected, the high AS participants reported more pain in response to the cold pressor on the Present Pain Index (PPI) of the SF‐MPQ than did the low AS participants. High AS participants did not differ from low AS participants on other aspects of the cold pressor response (e.g. pain threshold, pain tolerance, pain recovery). These results support the role of pain‐related fear as a mediating variable between AS and increased perceived pain intensity.     

Toward a social psychophysiology of vagally mediated heart rate variability: Concepts and methods in self‐regulation,emotion, and interpersonal processes

Theory and research on self‐regulation, emotional adjustment, and interpersonal processes focus increasingly on parasympathetic functioning, using measures of vagally mediated heart rate variability (vmHRV) or respiratory sinus arrhythmia (RSA). This review describes models of vmHRV in these areas, and issues in measurement and analysis. We propose a framework organizing theory and research as examining (a) vmHRV as an individual difference or a situational response, and (b) resting, reactive, or recovery levels. Evidence supports interpretation of individual differences in resting vmHRV as a broad biomarker for adaptive functioning, but its specificity and underlying mechanisms require elaboration. Individual differences in vagal reactivity (i.e., trait‐like differences in vmHRV decreases during challenge or stress) are less commonly studied in adults and results are mixed. Many stressors and challenges evoke temporary decreases in vmHRV, and in some research self‐regulatory effort evokes increases. In a smaller literature, positive interpersonal experiences and some restorative processes increase resting vmHRV, whereas depletion of self‐regulatory capacity through related effort decreases it. Greater attention to conceptual distinctions regarding vmHRV constructs and several methodological issues will strengthen future research. Importantly, researchers should exercise caution in equating vmHRV with specific psychosocial constructs, especially in the absence of converging assessments and precise experimental manipulations.     

Effect of Acute Psychological Stress on Motion-in-Depth Perception: An Event-Related Potential Study

The present study explored the intrinsic event-related potential (ERP) features of the effects of acute psychological stress on the processing of motion-in-depth perception using a dual-task paradigm. After a mental arithmetic task was used to induce acute psychological stress, a collision task was used to evaluate motion-in-depth perception. The error value and average amplitude of late slow waves (SW) were significantly larger for the earlier colliding spheres’ than for the later colliding spheres. The P1 peak latency in the left occipital region was significantly shorter than that of the right occipital region in the motion-in-depth perception task. Compared to the control condition, the estimated value of residual time-to-collision and error value were significantly reduced, and the N1 peak amplitude and the SW averaged amplitude were significantly increased in the stress condition. Longer motion-in-depth time improved discrimination accuracy and decreased the investment of cognitive resources. Acute psychological stress increased behavioral performance and enhanced attention resources on the motion-in-depth perception task together with greater investment of cognitive resources.

CXCR4和CXCR7在甲状腺癌中的表达及病理意义

研究甲状腺癌组织中趋化因子4受体（CXCR4）和趋化因子7受体（CXCR7）的表达情况及临床病理意义。应用免疫组织化学PV-6000法及Westernblot法检测CXCR4与CXCR7在甲状腺癌中的表达。二者在甲状腺癌与甲状腺良性疾病组织的差异均具有统计学意义（P〈0．05）,在甲状腺癌中表达仅与淋巴结转移有关（P〈0．05）,CXCR4与CXCR7之间呈正相关。Westernblot结果提示二者在甲状腺癌中的表达率高于癌旁及甲状腺腺瘤。CXCR4和CXCR7的表达水平与淋巴结转移相关,可作为甲状腺癌预后的判断指标。     

替格瑞洛与氯吡格雷对急性STEMI患者急诊PCI术后炎症因子的影响

为比较替格瑞洛与氯吡格雷对急性ST段抬高型心肌梗死（STEMI）患者急诊经皮冠状动脉介入术（PCI）术后炎症因子的影响,将176例急性STEMI且行急诊PCI术的患者分为替格瑞洛组（A组）58例、氯吡格雷常规组（B组）58例、氯吡格雷强化组（C组）60例,分别测定术前、术后12小时、术后7天、术后1个月、术后3个月、6个月时炎症因子e反应蛋白（CRP）、白细胞介素-6（IL6）、髓过氧物酶（MPO）、可溶性CD40受体（sCD40L）的含量,比较3组患者各炎症因子在不同时间点有无统计学差异。结果显示c组和A组较B组明显降低（P〈0．05）,有统计学意义,而A组较c组稍降低（P〉0．05）,但两者无统计学意义。由此可见,替格瑞洛的抗炎作用较常规剂量氯吡格雷作用明显增强,和强化剂量氯吡格雷作用相仿。
