宫颈癌普查与人文关怀

宫颈癌的发病率居女性恶性肿瘤的第二位,只要做到旱发现、早诊断、旱治疗,宫颈癌是一种可以预防和治愈的疾病.认真地做好宫颈癌的普查和随诊,能够降低宫颈癌的发病率和病死率.因为宫颈液基细胞学设备简单,方法便利,阳性检出率高,目前已成为基层医疗单位开展宫颈癌普查的重要手段.提倡宫颈癌的普查是对全社会育龄妇女健康的关怀,是医学人文精神的具体体现.全社会的妇女都应享有这种人文关怀.     

针对T细胞介导的胰岛自身免疫的治疗策略

1A型糖尿病是由T细胞所介导的器官特异性自身免疫性疾病.人们利用转基因技术、自身抗原疫苗接种、单克隆抗体治疗等新兴技术通过诱导自身免疫耐受,改变免疫调节因子,调节细胞凋亡等途径阻止了自身免疫反应对胰岛的攻击.这些针对其发病机制所提出的新型治疗策略让人们看到了治疗自身免疫型糖尿病的希望.     

心理治疗的消极后果

心理治疗消极后果是指由于心理治疗本身直接导致的来访者病情恶化。消极后果表现形式多样,对其测量应全面而仔细确证。消极后果的影响因素众多,包括来访者中有人格病理诊断、人际功能障碍、他评病情严重、对治疗期望不正确和动机低下;治疗师缺乏共情、对来访者出现负性反移情、低估来访者病情和错误使用治疗技术;潜在有害疗法。对其预防包括治疗前对治疗师和疗法进行规范和治疗中采用聚焦来访者的研究减少消极后果发生率。最后提出目前研究中存在测量、研究单位选择和伦理等难题,未来研究应全面呈现研究数据、采用RCT研究确定消极后果发生率、用交互作用研究模式寻找消极后果影响因素以及对中介变量的研究探询消极后果发生机制。     

心理治疗结果的临床显著性分析方法

心理治疗结果研究中,如何对结果测量数据进行统计分析,是非常重要的环节之一。研究者发现,不能简单使用统计显著性来考察心理治疗的结果,因而引入了临床显著性的概念以便更准确地从临床角度考察治疗的情况。在验证临床显著性改变中,西方学者提出了JT法、GLN法、EN法和HA法等统计分析方法,这些方法都试图更准确地分析临床显著性,但在心理治疗结果研究中,这些方法仍然存在概念明确性、标准和数据收集完善性等方面的问题。因此今后的研究应该关注方法的创新或修订,还是关注数据解释是目前西方关于临床显著性分析方法的两大争论。国内也应在心理治疗结果的研究中引入临床显著性分析方法,同时还应考虑效果评价指标的设立和有效测量工具编制的问题,为正确评价心理治疗结果服务,并最终为提高心理治疗效果服务。     

Coordination of complex bimanual multijoint movements under increasing cycling frequencies: The prevalence of mirror-image and translational symmetry

The present study examined the principles underlying inter and intralimb coordination constraints during performance of bimanual elbow–wrist movements at different cycling frequencies (from 0.75 Hz to 2.50 Hz). Participants performed eight coordination tasks that consisted of a combination of in-phase (IN) and/or anti-phase (AN) coordination modes between both elbows and wrists (interlimb), with isodirectional (Iso) or non-isodirectional (NonI) coordination modes within each limb (intralimb). As expected, the principle of muscle homology (in-phase coordination), giving rise to mirror symmetrical movements with respect to the mid-sagittal plane, had a powerful influence on the quality of global coordinative behavior both between and within limbs. When this principle was violated (i.e., when the anti-phase mode was introduced in one or both joint pairs), the non-isodirectional intralimb mode exhibited a (de)stabilizing role in coordination, which became more pronounced at higher cycling frequencies. However, pattern loss with increasing cycling frequency resulted not only in convergence toward the more stable in-phase patterns with the elbows and wrists but also to the anti-phase patterns (which were associated with directional compatibility of within-limb motions). Moreover, participants generally preserved their initial mode of coordination (either in-phase or anti-phase) in the proximal joints (i.e., elbows) while shifting from anti-phase to in-phase (or vice versa) with their distal joint pair (i.e., wrists). Taken together, these findings reflect the impact of two immanent types of symmetry in bimanual coordination: mirror-image and translational symmetry.     

Comparison of self-concepts of students identified as gifted and regular students.

The purpose of the present study was to compare the self-concepts of 40 eighth grade students identified as gifted and 40 regular eighth grade students using the Piers-Harris Children's Self-concept Scale. A t test indicated a significant group difference on the behavior component only and no significant differences by gender. More similarities than differences were noted in self-concepts of these students identified as gifted and regular students.     

Attentional capture and inhibition (of return): the effect on perceptual sensitivity

The present study was designed to determine the spatial distribution of attention in displays in which an irrelevant color singleton was present. The results show that at the location of an irrelevant singleton, there is, first, an increased sensitivity (d'), followed later by a reduced sensitivity. The increased sensitivity implies that, first, the irrelevant singleton captured spatial attention, producing an increased sensory gain for input at the irrelevant distractor location. The later-occurring, reduced sensitivity implies the operation of inhibitory processes, possibly related to inhibition of return.     

The use of ecological momentary assessment to test appraisal theories of emotion

Although appraisal theories have received strong empirical support, there are methodological concerns about the research, including biased recall, heuristic responding, ethical issues, and weak and unrealistic induction of emotions in laboratories. To provide a more ecologically valid test of appraisal theories, the authors used ecological momentary assessment, in which the emotions and appraisals of Singaporean police officers were measured online over the course of an ordinary workday. The research focused on happiness. Support was obtained for predictions, demonstrating the generalizability of appraisal theories to a nonlaboratory setting and circumventing the shortcomings of previously used methodologies. Also, evidence was obtained that happiness was reported primarily in association with a specific combination of 3 relevant appraisals: high pleasantness, high perceived control, and low moral violation.     

自我同一性状态对时间透视体验的结构关系研究

用自编的大学生自我同一性状态量表和时间秀视体检量表对６４１名大学生时间透视的心理结构关系进行了测量。结果表明,在自人达成型与扩散两种没的同一性状态下,不仅对过去、现在、预期未来和理想未来的时间体验上均有积极与消极之分,而且在各种时间体验之间的结构关系上,前者的结构更为清晰,后者更为混乱,从而初步证实了自我同一性状在时间透视体验中的整合作用。
