持续正压通气治疗睡眠呼吸暂停低通气综合征的接受意向调查

探讨影响持续气道内正压通气(CPAP)治疗阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的接受性的非技术因素。设计OSAHS认知度和CPAP意向调查表、信赖他人量表,60例OSAHS患者经健康教育后,100例健康志愿者随机填表,结果做统计分析。两组中43.3%和5%基本了解OSAHS(P<0.01);10%和5%表示接受CPAP(P>0.05);85%和90%认为CPAP机价格高(P>0.05)。量表得分:两组得分分布近似,高分比例大,添加题90%和80%选择负性答案。目前公众对OSAHS认知差,对医生的信任度低,而CPAP机价格高,患者对CPAP接受性差。     

Differences in visual orienting between persons with Down or fragile X syndrome

The voluntary and reflexive orienting abilities of persons with Down syndrome and fragile X syndrome, at average MA levels of approximately 4 and 7 years, were compared with an RT task. Reflexive orienting abilities appeared to develop in accordance with MA for the participants with Down syndrome but not for those with fragile X syndrome. However, both groups showed delayed voluntary orienting. The group differences in reflexive orienting at the low MA level reinforce the practice of separating etiologies and highlight the contribution of rudimentary attentional processes in the study of individuals with mental retardation.     

Attentional set-shifting in fragile X syndrome

The ability to flexibly adapt to the changing demands of the environment is often reported as a core deficit in fragile X syndrome (FXS). However, the cognitive processes that determine this attentional set-shifting deficit remain elusive. The present study investigated attentional set-shifting ability in fragile X syndrome males with the well-validated intra/extra dimensional set-shifting paradigm (IED) which offers detailed assessment of rule learning, reversal learning, and attentional set-shifting ability within and between stimulus dimensions. A novel scoring method for IED stage errors was employed to interpret set-shifting failure in terms of repetitive decision-making, distraction to irrelevance, and set-maintenance failure. Performance of FXS males was compared to typically developing children matched on mental age, adults matched on chronological age, and individuals with Down syndrome matched on both mental and chronological age. Results revealed that a significant proportion of FXS males already failed prior to the intra-dimensional set-shift stage, whereas all control participants successfully completed the stages up to the crucial extra-dimensional set-shift. FXS males showed a specific weakness in reversal learning, which was characterized by repetitive decision-making during the reversal of newly acquired stimulus-response associations in the face of simple stimulus configurations. In contrast, when stimulus configurations became more complex, FXS males displayed increased distraction to irrelevant stimuli. These findings are interpreted in terms of the cognitive demands imposed by the stages of the IED in relation to the alleged neural deficits in FXS.     

Social Information Processing Skills in Children with Histories of Heavy Prenatal Alcohol Exposure

Based on caregiver report, children with prenatal alcohol exposure have difficulty with social functioning, but little is known about their social cognition. The current study assessed the social information processing patterns of school-age children with heavy prenatal alcohol exposure using a paradigm based on Crick and Dodge’s reformulated six-stage model. Fifty-two children (aged 7–11) with and without heavy prenatal alcohol exposure were tested using a structured interview measure of social information processing involving 18 videotaped vignettes of children in group entry and provocation situations. Alcohol-exposed children displayed maladaptive processing patterns on the goal, response generation, and response evaluation steps in group entry situations, and encoding, attribution, response evaluation, and enactment steps during provocation situations. Children with heavy prenatal alcohol exposure also had difficulty on the Test of Problem Solving, and performance correlated with social information processing measures. Such difficulties may lead to problems in social functioning and warrant early intervention.     

The relationships among verbal short-term memory, phonological awareness, and new word learning: evidence from typical development and Down syndrome

This study examined the correlates of new word learning in a sample of 64 typically developing children between 5 and 8 years of age and a group of 22 teenagers and young adults with Down syndrome. Verbal short-term memory and phonological awareness skills were assessed to determine whether learning new words involved accurately representing phonological information in memory. Results showed a relationship between verbal short-term memory measures and typically developing individuals’ ability to learn the phonological form of novel words but not their ability to learn the physical referent of new words. Similarly, individuals with Down syndrome showed impaired verbal short-term memory and impaired form but not referent learning. Together, these findings specify the circumstances in which an accurate phonological representation within short-term memory is required for new word learning.     

急性冠脉综合征患者血液Rho激酶活性分析

探讨 Rho 激酶（ROCK）活性与急性冠脉综合征（ACS）患者冠状动脉狭窄程度及预后的关系。选取2012年6月至2013年3月住院的129例患者,其中急性心肌梗死（AMI）组68例、不稳定型心绞痛（UA）组30例、对照（CON ）组31例。Western Blot 检测血液白细胞中 ROCK 、ROCK1、ROCK2活性,同时根据冠状动脉的狭窄程度及是否发生心血管意外分组再次比较。 AMI 组和 UA 组 ROCK 、ROCK1、ROCK2活性均增高;且 AMI 组高于 UA 组;三支、双支、单支病变组活性依次减低,Gensini 评分≥20分组及发生心血管意外组均高于 Gensini 评分＜20分组及未发生心血管意外组,差异均有统计学意义（P＜0．05）。 ROCK 活性可能对 ACS 患者预后观察、评估有重要意义。     

Chronic glucocorticoid hypersecretion in Cushing’s syndrome exacerbates cognitive aging

Cumulative exposure to glucocorticoid hormones (GC) over the lifespan has been associated with cognitive impairment and may contribute to physical and cognitive degeneration in aging. The objective of the present study was to examine whether the pattern of cognitive deficits in patients with Cushing’s syndrome (CS), a disorder characterized by chronic exposure to elevated levels of glucocorticoids (GC), is similar to that observed in older individuals. Ten subjects with CS were compared to sex-, age-, and education-matched healthy controls and older subjects (age of CS subjects + 15 yr). All participants were administered tests to assess attention, visuospatial processing, learning and memory, reasoning, concept formation and verbal fluency. MANCOVAs with depression scores as covariate and polynomial contrasts revealed that the age-matched control group performed better than the CS and older subject groups in visual target detection, trail making test, stroop task, digit symbol substitution, block design, object assembly, visual reproduction, spatial memory and similarities. The CS and older subjects performed similarly on these tasks. Further, a principal component analysis revealed two significant factors, representing general cognitive function and verbal memory explaining 39.9% and 10.0% of the variance, respectively. Additional MANCOVAs with depression as a covariate revealed that CS and older control subjects showed impaired performance on general cognitive function compared to age-matched controls. These results suggest that hypersecretion of GCs has “aging-like” effects on cognitive performance in individuals with CS.
