ABSTRACT
Objective To study the diffusion tensor imaging (DTI)features in acute cervical spinal cord injury (CSCI)and evaluate its clinical value.Methods Eight patients with acute CSCI (within 72 hours after onset)were performed conventional MRI and fast DTI scans (112 seconds)and diffusion tensor tractography (DTT)at 3.0T Siemens Trio Tim system.Meanwhile,the fractional anisotropy (FA) values and apparent diffusion coefficient (ADC)values were calculated separately in the site of lesions,the upper and lower sections to the lesions.Then the data were analyzed by paired-samples t test analysis with SPSS 13.0 software.Results Cervical spinal cord injury occurred likely in the sites of C5-C6 (account for 4/8)and C4-C5 (account for 3/8).All MRI and DTI images were satisfied for clinical diagnosis.The FA value and ADC value of injury lesions were markedly lower than that of the normal cord.Accordingly,the injury lesions on FA map and ADC map presented low signals.There were no significant differences of FA values and ADC values between the upper and lower sections to the lesions.DTT could help in displaying the disruption of spinal fiber tract in lancination case and distortion fibers in closed cervical spinal cord injury.Conclusion Fast DTI sequence at 3.0 Tesla may obtain the qualified spinal cord images.By calculation of FA values and ADC values in CSCI patients,DTI may play an important role in detecting the changes of anisotropy and water diffusion caused by myelin sheath injury and cytotoxic edema and vasogenic edema respectively.
ABSTRACT
Objective To investigate the early diagnosis value of MR by detecting spinal inflammatory lesions in ankylosing spon-dylitis (AS).Methods Forty patients were involved in this study,including 20 cases with short inflammatory back pain (IBP)histo-ry (duration ≤18 months)and 20 cases with long IBP history (duration ≥24 months).MR images were analyzed retrospectively. Results Patients with a short history of IBP had 7 lesions in vertebral bodies (anterior/posterior spondylitis and spondylodiscitis) and 33 lesions in posterior spinal structures (arthritis of costovertebral joints,costotransversal joints,zygapophyseal joints and en-thesitis of spinal ligaments).Patients with a long history of IBP had 27 lesions in vertebral bodies and 24 lesions in posterior spinal structures.Patients with a short history of IBP had significantly more lesions in posterior spinal structures than in vertebral bodies with 82.5% (33/40)vs 1 7.5% (7/40),respectively (P <0.01).In contrast,patients with a long history of IBP had significantly more inflammation in vertebral bodies with 79.4% (27/34)vs 20.6% (7/34),respectively (P <0.01).Conclusion Inflammatory spinal lesions in patients with a short history of IBP are seen more often in the posterior structures.Early detection of inflammatory spinal lesions by MRI is useful for early diagnosis of AS.
ABSTRACT
The somatic symptoms of patients with depressive disorder in a general hospital were retrospectively analyzed.From May 2004 to April 2009,736 patients in Psychological Clinic were diagnosed as depressive disorder,among them 723(98.2%)had somatic complains.The somatic symptoms were complex and involving several systems,nervous system,digestive system and cardiovascular system were the most common.It is necessary to recognize the typical somatic symptoms of depressive disorders to avoid misdiagnosis.
ABSTRACT
<p><b>OBJECTIVES</b>The purpose of this study was to assess how changes from different baselines of activities of daily living (ADL) can be explained by marital status, living arrangement and healthcare.</p><p><b>METHODS</b>Using data from the Chinese Longitudinal Health Longevity Study conducted in 2002 and 2005, 8,099 surviving and 3,822 deceased elderly aged 65 years and over were evaluated using multinomial logistic regression.</p><p><b>RESULTS</b>After adjusting for demographic, socioeconomic and health factors, elderly who were either married or living alone were less likely to encounter ADL decline compared to their counterparts. This was true only for those with fully independent ADL at baseline. Notably, once the functional status of the elderly declined from baseline and they became dependent on others, the status of living alone was no longer a significant predictor of the rate of future decline. On the other hand, elderly who had a spouse, children or other relatives as caregivers were more likely to experience a faster recovery and lower likelihood of death, compared to those who were cared by unrelated live-in caregivers. In addition, Chinese elderly with health insurance had a lower likelihood of death than their counterparts lacking health insurance, among those with ADL at the dependent baseline.</p><p><b>CONCLUSIONS</b>Although there has been a change in family structure and living arrangements, the majority of Chinese elderly still rely on traditional forms of family support, especially after acquiring dependency status. As the elderly have different functional levels, healthcare policies in China should consider the need for both community and family support systems.</p>
ABSTRACT
This study was to analyze 1400 first-visit psychology outpatients from 8 May 2004 to 30 June 2007 in Zhangzhou Hospital,Fujian Medical University.Our results showed that of all the participants,the following patients were more commonly seen:female,teenagers or mid-age less than 50,and lower education level.Regarding to mental diseases,hysteria,serious stress disorders or adjustment disorder,and neurosis were the leading diagnosis,followed by mood disorder,schizophrenia or other psychosis disorders,and apparatus psychosis disorders.
