ABSTRACT
Objective:To investigate the demands for cardiac rehabilitation information in patients with coronary atherosclerotic heart disease (CHD) and influential factors.Methods:Information demands for cardiac rehabilitation in CHD patients were surveyed by questionnaire and the influential factors were analyzed by one-way ANOVA and multi-factor analysis of variance.Results:The score of demands for cardiac rehabilitation information in CHD patients was 3.86±0.53.Among them,the most urgent top 5 items were:drug knowledge,diagnosis and treatment,basic knowledge of the heart,emergency and safety and nutrition knowledge.The top 3-demand modes were:communication with medical workers,movies or videos to take home,and lectures.The score of demands for cardiac rehabilitation information was different in different age groups.The highest score was in the patients with age less than 60.There were different demands in different characteristic groups.Conclusion:The most urgent need and mode are drug knowledge and communication with medical workers,respectively.With the age increase,the demands for patients' cardiac rehabilitation information decrease.An individualized health education strategy should be developed according to the characteristics of CHD patients.
ABSTRACT
OBJECTIVE@#To systematically evaluate the image and pathological features of Ewing's sarcoma (ES) in the oral and maxillofacial region. @*METHODS@#Eight patients with ES in the oral and maxillofacial region were enrolled for this study. The X-ray, computed tomography (CT), and magnetic resonance imaging (MRI) of ES and the pathological data were systematically evaluated. @*RESULTS@#X-ray image showed a diffuse radiolucency with cystic component and ill-defined borders for bone lesion. CT showed that there was osteolytic mass with extensive bone destruction and soft tissue infiltration, but no periosteal reactions were observed. MRI demonstrated that ES showed an inhomogeneous structure and blurred borders with invasion to adjacent soft tissue for bone lesion. Similar manifestation also showed in MRI images for patients with soft tissues. Histologically, ES composed of small round cells, and expressed CD99, neuron specific enolase (NSE) and vimentin (Vim) in all patients. Desmin (Des), CD34, epithelial membrane antigen (EMA), chromogranin A (ChgA), etc, were negatively expressed in ES cells. @*CONCLUSION@#X-ray, CT, and MRI are helpful to determine the property, extent and the relationship of ES with the surrounding tissues. Immunohistochemical stain of CD99, NSE, and Vim are helpful to confirm the pathological diagnosis of ES.

Objective To discuss the effects of Modic II changes on clinical outcomes of discectomy for lumbar disc herniation (LDH) with low back pain associated with unilateral sciatica. Methods Sixty-five cases of LDH with low back pain associated with unilateral sciatica received single segment discectomy during January 2007 to January 2009.There were 30 cases with Modic Ⅱ changes in group A, 35 cases without Modic Ⅱ changes in group B. Assessed the clinical outcomes by using MacNab analyzing system and visual analog scale (VAS). Results Two groups of the postoperative clinical symptoms had significant relief, the follow-up of 12 - 36 months, average (20.6 ± 7.5) months. MacNab efficacy evaluation by group A of optimal 10 cases (33.33%), good 17 cases (56.67%), general 3 cases (10.00%). Group B optimal 28 cases (80.00%), good 5 cases (14.29%), general 2 cases (5.71%), there was significant difference in fine rate (P<0.05). Preoperative group A VAS was ( 8.67 ± 0.30) scores, group B was (8.60± 0.32 ) scores (P>0.05). Postoperative group A VAS was (2.63 ± 1.30) scores,group B was (1.09 ±0.50) scores (P< 0.05). Conclusion Modic Ⅱ changes may be one of the reasons which cause the residual low back pain after the discectomy for LDH.
ABSTRACT
Objective To analyze the differential gene expression profiling of liver in rats subjected to hemorrhagic shock(HS) and sham hemorrhage shock(SHAM) by gene chip technology, thus to evaluate the possible molecular pathogenesis of HS. Method 20 male Wistar rats were randomly divided into a SHAM group and a HS group, with 10 rats in each group. Hepatic gene expression profiles were detected by oligonucleotide microarrays of 5705 mouse genes in two groups for three times. Genes with ratio(R) > 2 were identified as up-regulated and R < 0.5 were identified as down-regulated. Biological function of differentially expressed genes was analyzed and 9 genes were selected to undergo semi-quantitative RT-PCR. Results Among the total 5705 probes detected,86 genes showed differential expression in HS group comparison with SHAM group. The expression levels of 72 genes were up-regulated while those of 14 genes were down-regulated significantly. Differentially expressed genes were classified according to their biological function: transport genes, transcription regulator genes, signaling genes, response to stress genes, metabolic genes, development genes and cell adhesion genes. Conclusions cDNA microarray is an efficient and high-throughout method to survey gene expression profiles in HS.The variation of those gene expressions might be a potential pathogenic mechanism for HS that may offer a novel target for further study of therapeutic strategies of HS.
