伦理,胚胎和干细胞研究

道德是关于规则、直觉、理解和观点的一个复杂系统。而后者影响着我们相互间处理事务的方式。它们交叉地渗入我们的道德思考。这种思维与胚胎、干细胞的伦理密切相关,因为胚胎和干细胞涉及我们对与治疗和移植组织有关的人的生命及其启始问题。就像在许多对待生命及其可以阐释的研究方法方面,要有一个道德的思辩历程一样,解决这些问题,部分地需要讨论,部分地需要回答。只有在我们认定这种讨论能够融入应用干细胞治疗的胚胎及其类源和人体组织的使用中时,我们才会清楚,大多数人体不同部位的干细胞应用是经过了对人的生命启始、我们儿童、家庭进行了思考。

环氧化酶-2研究的历史回顾与启示

通过对COX-2研究的回顾,阐明了COX-2在炎症增生,及在肿瘤的发生发展中的作用,认识到了COX-2作为肿瘤的化学预防和治疗靶点的前景.并从哲学的观念阐明了在COX-2研究过程的体会和认识及展望,认为用联系的观念和辨证的观念进行科学研究,可以触类旁通,获得更加可靠的证据,更快地得出真实的结论.     

错觉图空间原象的体视和解析识别

错觉图是具有特殊生理、心理效应的两维图,包括悖理型、坐标阙如型、过渡变形型和双关两可型等几类。有的是在两维平面上表达类似三维的不可能虚构体,造成与实际三维知觉经验的强烈矛盾;有的则具有多重涵义,并以心理操作或图形的动态为条件产生变幻,造成各种幻觉感。长期以来,在生理心理学和图学研究中,仅仅触及了一些错觉图的幻觉现象,极少研究其中的错觉机制。错觉图不但给现有的三维和多维几何理论造成混乱,而且也在工程图的表达和判读中造成一些错觉而导致事故。本文从体视理论和图学分析方面对错觉机制进行了定量和定性分析。提出了形体重影机制、变换组合机制、范围渐变机制和方位移动机制等几种致幻理论,并运用上述理论以国内外常见的错觉图为实例,对形成错觉的图学、几何学和心理生理学过程做了具体论证,从而揭示了错觉图的错觉机制。     

Assessing Psychiatric Symptoms in Youth Affected by HIV: Comparing a Brief Self-Administered Rating Scale with a Structured Diagnostic Interview

Brief psychiatric assessment tools are needed for evaluating children affected by HIV for emotional and behavioral problems. We compared a self-administered symptom rating scale (CASI-4R) to a semi-structured diagnostic interview (DICA-P) in 136 U.S. children affected by HIV. Agreement and performance measures for the two instruments were computed for attention deficit hyperactivity disorder, depression, anxiety, and disruptive behavior. Correlations and regression analyses were conducted to compare the two instruments, and to evaluate their associations with social, academic, and global function. Higher CASI-4R symptom severity scores were associated with DICA diagnoses (p?<?0.02 for all disorders). Agreement (κ) between DICA diagnoses and CASI-4R Clinical Cutoffs (which incorporated symptoms and impairment) was low to moderate (0.19–0.40 for all disorders). Thirty-two percent of cases with a DICA diagnosis were identified by the CASI-4R Clinical Cutoff (sensitivity), yet over 90% of DICA-negative cases were negative by the CASI-4R (specificity). Sensitivity was higher using CASI-4R Severity Score thresholds based on median scores compared to the DICA diagnoses. The presence and severity of psychiatric symptoms and impairment were associated with poorer academic, social, and global function. The CASI-4R symptom checklist can be used to inexpensively screen youth affected by HIV for emotional and behavioral problems, although it is important that there be appropriate mental health evaluation follow-up.     

Community-delivered infant–parent psychotherapy improves maternal sensitive caregiving: Evaluation of the Michigan model of infant mental health home visiting

The current study evaluated the effectiveness of a home-based psychotherapeutic Infant Mental Health Home Visiting (IMH-HV) intervention for enhancing parenting sensitivity; a secondary aim was to evaluate whether the use of video feedback was associated with greater treatment response. Participants were N = 78 mothers and their children (age at entry ranged from prebirth to 24-month old (M = 9.8, SD = 8.4), who were initiating IMH-HV services with community mental health-based therapists (N = 51). Dyads were assessed during extended home visits via standardized interviews and observational and questionnaire methods within the first month of treatment (baseline), and again 6 and 12 months thereafter. Following each of these extended home visits, study evaluators completed a standard Q-sort to capture observations of maternal sensitivity during the visit. Therapists completed fidelity checklists used to derive the total number of IMH-HV sessions received (i.e., dosage) and frequency with which therapists provided video feedback. Results indicated a dose–response relationship between number of sessions and maternal sensitivity, and that video review with parents independently contributed to improved maternal sensitivity. Discussion focuses on the effectiveness of this community-based psychotherapeutic home visiting model for enhancing parenting, as well as the value of video feedback as a specific therapeutic strategy.     

CDCC婴幼儿智能发育量表的编制

CDCC婴幼儿智能发育量表主要是根据Bayley量表结合我国儿童的实际情况编制而成的。本量表是评价0—3岁儿童智能发育的诊断性量表,用来评价和分析儿童的早期发展。因而它是优生优育和早期教育的一个有效工具。它既可以为儿童工作者,尤其是儿科、儿保工作者,儿童教育工作者以及广大的托幼保教工作人员在对儿童进行诊断、治疗和教育时作为依据,也可以用作研究工作者在研究影响儿童发育的因素(例如:遗传、营养、环境等因素)的一个诊断工具,提供比较确切的数据。
