Objective To assess diastolic functions of right ventricle in patients with essential hypertension by Doppler tissue imaging (DTI) technique.Methods Sixty patients with essential hypertension were enrolled.According to Ganau categories,these patients were divided into four groups as following: normal left ventricle(Ⅰgroup,14 cases), concentric remodeling(Ⅱgroup,13 cases), concentric hypertrophy(Ⅲgroup,18 cases) and eccentric hypertrophy(Ⅳ group,15 cases),and 20 age matched healthy subjects as control group were included.DTI data were acquired from tricuspid annular on apical four chamber and right ventricular two chamber views.Results Compared with control group,Ea/Aa

Objective To develop and test a stressor scale for in-patients with spinal cord injury (SSIPSCI). Methods Based on in-depth interviews and the second-level International Classification of Functioning, Disability, and Health (ICF) categories, a 39-item SSIPSCI was generated and pilot tested. It was then used with 284 inpatients with spinal cord injury. Principal components factor analysis and correlation analysis were performed.Results The exploratory components factor analysis revealed 7 significant stress factors: social activity, economy security, individual activity, relationship with others, physical disorders, bowel and bladder problems and medical fees. Internal consistency was high, with a Cronbach's alpha coefficient of 0. 950 overall and 0. 741 ～ 0. 920 for the individual factors. Test-retest reliability was 0.848. The correlation between SSIPSCI scores and Beck depression inventory (BDI) scores was strong ( r = 0. 665 ). Conclusions The reliability and validity of the SSIPSCI are both satisfactory enough to meet psychometric requirements.

ObjectiveTo observe the effects of attention training with conventional cognitive training on cognitive impairment after stroke. Methods52 cases with cognition dysfunction after stroke were divided into the attention training group and conventional cognitive training group. They were assessed with Basic Cognitive Ability Test, Mini Mental State Examination (MMSE), Barthel Index, and National Institutes of Health Stroke Scale （NIHSS） before and 8 weeks after training. ResultsAll the patients improved their cognitive function after training, but the attention training group improved more in the digit span test, two-word recognition, and MMSE score than the conventional cognitive training group. ConclusionAttention training is a useful way to improve cognitive function in patients after stroke.
