关键词： Individual Differences   Injury Severity   Traumatic Brain Injury  

摘要： Research Objectives: This study describes differences in demographics, emotional functioning, life satisfaction, functional status, and symptom complaint in a sample of adults with traumatic brain injury (TBI) upon admission to a brain rehabilitation clinic, based upon injury severity classified using the Mayo Classification System for TBI severity (MCS). Design: Measures were administered to assess individual differences in mood, life satisfaction, participation, and level of symptom complaint between groups differing in injury severity. Setting: Patients were referred to an outpatient brain treatment program with a diagnosis of TBI associated with symptom complaints and change in functioning. Participants: Thirty-three patients were presenting for treatment to an interdisciplinary outpatient treatment clinic with TBI (Definite=13, Probable=7, Possible=13) (Mean age of patient=42.76 years, Range: 23-76 years; females=16, males=17; Mean time since injury = 24.45 months, Range: 1-282 months). Due to the small sample size of Probable TBI patients, Probable and Possible TBI patients were combined into one group. Interventions: N/A. Main Outcome Measure(s): All patients were classified for injury severity using the Mayo Classification System. Participants also completed the Mayo Portland Participation Index (M2PI), the Satisfaction with Life Scale (SWLS), the Patient Health Questionnaire (PHQ-9), and the Neurobehavioral Symptom Inventory (NSI-22). Results: Using an analysis of variance (ANOVA), between the Definite TBI group and the Probable/Possible TBI, there was a significant difference on the PHQ-9 scale (F=7.504, p=0.010) with the Definite TBI group (M=6.62, SD=5.30) reporting lower symptoms of depression than the Probable/Possible TBI group (M=12.45, SD=6.37). No significant difference was found between groups in life satisfaction (SWLS), neurobehavioral symptoms (NSI-22), or participation (M2PI). There is a difference in gender between Definite TBI and Probable/P

关键词： 血液检验   贫血鉴别   作用研究  

摘要： 目的：研究血液检验在贫血鉴别诊断中的作用价值.方法：选取2015年1月-2016年1月入院检查的贫血患者50例、地中海贫血患者50例以及健康体检者50例作为此次研究对象,将其命名为缺铁性贫血组、地中海贫血组以及健康组,均对其进行血细胞检测,观察3组人员血液中的RBC、MCV、Hb、MCH、RDW 各项指标的差异,对比缺铁性贫血组和地中海贫血组的灵敏度、特异性和符合率差异.结果：缺铁性贫血组和地中海贫血组的 MCV、MCH 指标低于健康组,地中海贫血组中的 Hb 指标低于地中海贫血组和健康组,组间比较差异明显具有统计学意义;缺铁性贫血组和地中海贫血组灵敏度、特异性和符合率比较无明显差异,不具有统计学意义.讨论：血液检验在贫血鉴别诊断中具有重要作用,并且具有临床参考价值.

摘要： 采用中学生情绪智力问卷、青少年害羞量表、简版礼会适应评估问卷对770名中学生（平均年龄为15．47岁，SD=1．94）进行测试．探讨情绪智力与社会适应的关系并分析羞怯在情绪智力与社会适应问的中介作用。阶层回归分析表明：在控制人口学变量后，情绪智力对积极适应具有正向预测作用，对消极适应具有负向预测作用；

关键词： Multi-category classification   Generalization error   Machine learning   Pattern recognition  

摘要： In a recent paper, the authors introduced the notion of sample width for binary classifiers defined on the set of real numbers. It was shown that the performance of such classifiers could be quantified in terms of this sample width. This paper considers how to adapt the idea of sample width so that it can be applied in cases where the classifiers are multi category and are defined on some arbitrary metric space.

关键词： Development   Epithelial-mesenchymal interaction   Microtissue   Spheroid   Three-dimensional cell culture  

摘要： We present an experimental method allowing the production of three-dimensional organ-like structures, namely microtissues (MTs), in vitro without the need for exogenous extracellular matrix (ECM) or growth factors. Submandibular salivary glands (embryonic day ED14), kidneys (ED13) and lungs (ED13) were harvested from mouse embryos and dissociated into single cells by enzyme treatment. Single cells were seeded into special hanging drop culture plates (InSphero) and cultured for up to 14 days to obtain MTs. This strategy permitted full control of the quantity of seeded cells. The development of the MTs into organs was followed histologically and immunohistochemically. Well-organized epithelial structures surrounded by a basal lamina were formed, as confirmed by transmission electron microscopy. Expression of E-cadherin, vimentin, fibronectin and alpha-SMA was compared in organs and corresponding MTs by real-time quantitative polymerase chain reaction. Branching morphogenesis was induced in MTs (as shown by histology and immunostaining for fibronectin and perlecan) and was conserved even after 14 days of culture. MTs continued their development and their epithelial structures were comparable with those of the physiological organ at postnatal day 2 (PN2). Expression of aquaporins was investigated to obtain better support for the functional differentiation of epithelial cells. Histogenesis proceeded and led to the start of organogenesis. This experimental model might improve our knowledge of epithelial-mesenchymal histogenesis and can be employed to study development or cellular organization during the embryonic formation of organs.
