基于共享理念的急诊CTA应急平台构建与效果评价

目的基于共享理念的急诊CTA应急平台构建与效果评价。方法选取2019年1—9月急诊CTA检查患者为对照组,2019年11月—2020年8月急诊CTA检查患者为观察组。对照组采用常规急诊值班制,观察组建立急诊CTA应急平台。对申请检查科室、检查项目进行描述性统计,比较两组CTA检查时间及入院患者预后转归情况。结果申请科室以急诊内科为主,检查项目以头颅、胸腹部为主,急诊CTA检查时间对照组中位数为46 min,观察组中位数为20 min,两组对比差异有统计学意义(P<0.05),对照组37例患者中有8例(21.7%)致残,观察组103例患者中有8例(7.8%)致残,两组对比差异有统计学意义(P<0.05)。结论组建急诊CTA应急平台能缩短急诊CTA影像学检查时间,降低致残率,提高患者生活质量,优化护理人力资源,值得临床推广。

Development of totally implantable electromechanical artificial heart systems: Baylor ventricular assist system

An implantable electromechanical ventricular assist system (VAS) intended for permanent use has been developed. It consists of a conically shaped pumping chamber, a polyolefin (Hexsyn) rubber diaphragm attached to a conically shaped pusher-plate, and a compact roller-screw actuator. Design stroke volume is 63 ml. The device weighs 620 g, and has a total volume of 348 ml. The pump can provide 8 L/min flow against 120 mm Hg afterload with a preload of 10 mm Hg. The inner surfaces are biolized by dry gelatin coating, with inflow and outflow ports accommodating tissue valves. Three subacute in vivo validation studies have been conducted in calves up to two weeks. The entire system functioned satisfactorily in both the fill/empty and the fixed-rate modes. There was no thromboembolic complication without anticoagulation. The pump showed reasonable anatomical fit inside the left thorax. This VAS is compact, efficient, quiet, and easy to control.     

从时空观释肾为先天之本--兼与张光霁、李如辉同志商榷

把肾为先天之本简单地理解为代与代之间的关系是错误的，其根源在于对中西医理论的差异缺乏清晰的认识，从而把中医的肾为先天之本混同为西医的遗传。以时空观为视角对中西医理论体系进行了宏观比较，在此基础上对肾为先天之本的深层内涵进行了阐释。     

美国中医学者对国内中医界的期盼

文章指出中国医学流入美国约50年，美国学者对此古老医学非常崇敬，认为中医学有很高的价值，中西医结合是未来医学发展之趋势，中医西医学化，中医新科技化，是大家必须去研讨之路。同时认为，中医要进一步发展必须改进传统观念，以学术科学为主，以传统经典为考，改进而不忘本，中医才能更加发扬光大。     

On Developing Self-concepts: A Controlled Study of Children and Adolescents with Autism

This study employed the self-understanding interview of Damon and Hart (1988) to assess the self-concepts of two groups of children and adolescents: a group of individuals with autism and a group of nonautistic mentally retarded individuals who were matched for age and for verbal ability. On the basis of an hypothesis concerning the interpersonal origins of social and psychological self-concepts (Hobson, 1990; Neisser, 1988), it was predicted that the participants with autism would show a relative dearth of such concepts in their talk about themselves. In accordance with our predictions, there was a significant group difference in the number and quality of statements that fell into the social category of self-concept; contrary to our predictions, however, there was no group difference in the number of statements that fell into the psychological category. In addition, although there were not significant group differences in the overall production of verbally expressed concepts concerning self-attributes of a physical, active, or psychological kind, even within these categories individuals with autism made fewer references to social interactions or qualities. These results are discussed with regard to theories of self-concept development in typically developing as well as autistic and mentally retarded individuals, and with reference to the limitations of interpersonal understanding ("theory of mind") in people with autism.

高中生自我概念与父母教养方式的相关研究

目的探讨高中生自我概念具体维度与父母养育方式之间的关系,为提高高中生的心理健康水平提供依据。方法采用田纳西自我概念量表和父母教养方式评价量表,对沧州市469名高中生进行调查。结果高中生的父母教养方式是影响自我概念形成的重要因素,不同的父母教养方式对子女的自我概念影响不同。对于不同性别高中生而言,自我概念总分、自我认同、自我满意和自我行动主要受同性别父母的情感温暖、理解因子的积极影响和异性别父母的过干涉、过保护和拒绝否认因子的消极影响。结论高中生自我概念主要受父母教养方式中同性别父母正向因子的积极影响和异性别父母负向因子的消极影响。     

建立中医概念的三维立体模式的可行性及意义

分析了当前中西医结合的误区,提出中医概念三维立体模式网络。按照客观到主观提炼的原则将中医概念分为若干层次,最高一层为中医纲领,底层为中医、西医基本概念,各个概念之间通过层次模式网络发生关联,最终形成的立体三维网将成为开放的、可以吸收新概念的中医概念模式网。
