Objective:To investigate the moderating role of emotional expressivity in the relationship between test anxiety and working memory capacity (WMC).Methods:Totally 332 college students were selected.The Test Anxiety Inventory (TAI),Emotional Expressivity Inventory (EEI) and Arithmetic Operation-Word Memory Span Task (OSPAN) were used to measure the severity of test anxiety,working memory capacity,and degree of emotional expressivity,respectively.Results:TAI scores were negatively correlated with WMC scores (r =-0.36,P ＜0.01).Emotional expressivity had a moderating effect between scores of test anxiety and WMC (β =0.19,P ＜0.01).Test anxiety score negatively predicted WMC score in students with low emotional expressivity (β =-0.74,P ＜ 0.01),whereas it couldn't predict WMC in those with high emotional expressivity (β =-0.07,P ＞0.05).Conclusion:It suggests that higher emotional expressivity could buffer the negative effect of test anxiety on working memory capacity.

目的探讨预测脑卒中康复结局的重要因素和可靠的预测模型。方法采用回顾性研究的方法,对北京博爱医院1999年1月—2001年7月收治的225例首次脑卒中患者的临床资料进行分析。患者的功能状态按照自行设计的日常生活活动能力 (activitiesofdailyliving ,ADL)量表进行评定。 结果尽管许多因素都会影响患者的功能恢复,但最有意义的3个因素是年龄、入院时的功能状态(ADL入院)和发病到康复治疗的间隔时间 (onset addmisioninterval,OAI)。年龄较小、ADL入院值较高、康复训练开始较早患者的ADL出院值较高。年龄与ADL增加值无关。预测模型:ADL出院 =49.52—0.14×年龄+0.66×ADL入院-0.03×发病到康复治疗间隔时间(R2=0.62,P=0.0001)。结论根据此模型,可预测患者出院时的功能状态(ADL出院),制定合理的康复目标和康复训练计划。

One hundred and five patients with non-ST segment elevation acute coronary syndrome were followed up for 1 year.They were assigned to the event group or non-event group according to the presence of endpoint events(cardiac death and nonfatM myocardial infarction).B-type natriuretic peptide level was measured at 30 days and 1 year and compared between the two groups.The results showed that the level of B-type natriuretic peptide was higher in the event group[(235±107)μg/L vs(154±49)μg/L at 30 days;(259±100)μg/L vs(143±57)μg/L at 1 year].Thus,B-type natriuretic peptide is an important prognostic factor for patients with non-ST segment elevation acute coronary syndrome.

ObjectiveTo investigate the influencing factors of nosocomial infection in rehabilitation department of children in our hospital.MethodsThe clinical data including infection part,infection time,immunoglobulin and length of stay of 532 cerebral palsy(CP) children was retrospectively investigated.ResultsSixty-one CP children got nosocomial infection.The nosocomial infection rate was 11.47%,the most common infection sites was respiratory tract(86.89%).March,April and November were the seasons easy to occur nosocomial infection.The levels of immunoglobulin of the infected children were lower than the normal children.ConclusionThe lower level of immunoglobulin,longer hospitalization,ventilation obstructed indoor,and season change maybe the important factors which leading a higher nosocomial infection rate for CP children.

ObjectiveTo investigate the risk factors of nosocomial infection (NI) of patients with spinal cord injury (SCI).MethodsClinical data of SCI patients hospitalized in our hospital from Jan 1999 to Dec 2004 were analyzed retrospectively.ResultsThe NI rate of SCI patients was 27.78%, and the highest was in summer (33.09%), the lowest was in winter ( 22.41 %). The most common infection sites were urinary tract (71.07%), followed by respiratory tract (14.72%).ConclusionSCI patients are susceptible to NI; prevention and control measures should be taken to decrease the NI rate.

目的探讨不同年龄组脑卒中患者康复结局的预测模型。方法对462例首次发病的脑卒中患者的临床资料进行回顾性分析。采用自行设计的日常生活活动能力(ADL)评定量表对其进行评定。结果总回归方程为:ADL出院=55.09+0.593ADL入院-0.17年龄-0.02OAI,复相关系数R=0.75,决定系数R2=0.56,校正的决定系数R2adjus=0.56;60岁以下年龄组回归方程为:ADL出院=52.27+0.51ADL入院-0.03OAI,R=0.69,R2=0.48,R2adjust=0.48;60岁以上年龄组回归方程为:ADL出院=34.46+0.73ADL入院,R=0.8,R2=0.64,R2adjus=0.64。60岁以上年龄组的预测模型准确性较高。结论按年龄分组可提高对脑卒中患者康复结局预测的准确性。

ObjectiveTo determine the normal values of the Comprehensive Function Assessment for Disabled Children. Methods60 healthy children ranged from 2 to 7 years old were evaluated with by the professional doctors. ResultsThe children ranged from 4 to 7 years old get scores above 90. The children ranged from 3 to 4 years old get scores above 80.The children ranged from 2 to 3 years old get scores above 60. Conclusions The Comprehensive Function Assessment for Disabled Children can evaluate the childrens develop ment entirely,detailedly and objectively. The normal values can be used to evaluate the children's function and the curative effect.

Objective To survey the situation of spinal cord injuries (SCI) in Beijing.Methods China Rehabilitation Research Center and Information Center of Beijing Health Bureau sponsored the surveillance of 86 hospitals in Beijing which had hospitalized SCI patients in 2002. The faculty of surveillance was composed of trained professionals. The number of registered SCI patients in 2002 was 1077, and 264 patients in 11 hospitals were chosen to be investigated in detail according to stratified sampling result.Results There were 1077 registered patients with a neurological deficit and the annual SCI incidence was 60 per million. The ratio of male to female was 3:1 and the ratio of cervical, thoracic, lumbar injuries and others is 4.9%, 28%, 66.7%, 0.4% respectively. The mean age at the time of injury was 41 years. The causes most frequently seen were falls from a height and traffic accidents. The mean time of hospitalization was 18.9 days and the mean expenditure of hospitalization was 27819.3 RMB. Four patients were transferred to rehabilitation hospitals, and others went homes directly after discharge.Conclusion There are many reasons for the high annual SCI incidence in Beijing and the first SCI cause was falling from a height, which should be pay special attention when the prevention measures are taken into account. The rate of SCI patients who received systemic medical rehabilitation was low.
