ABSTRACT
Objective:To analyze evaluation outcomes and influential indexes of 116 continuing medical education (CME) programs, and to offer references for ascertaining the quality evaluation focuses of CME programs.Methods:Chi-Square test and Fisher exact test were adopted to perform univariate analysis on evaluation outcomes of 28 indexes, and logistic regression was used for multivariate analysis.Results:Logistic regression showed that the indexes influencing the evaluation outcomes of programs qualified or not included consistency of basic information [ OR=6.712, 95%CI (1.314, 34.275)], whether textbooks provided by host institutions [ OR=109.386, 95%CI (2.577, 4 642.659)], whether the number of people in the meeting room equaled with the signature list [ OR=13.296, 95%CI (2.440, 72.456)], feedback of learners examination materials [ OR=19.069, 95%CI (3.713, 97.929)], feedback of teachers evaluation materials [ OR=13.497, 95%CI (2.672, 68.181)] and whether submit learners' credits according to regulations or not [ OR=51.326, 95%CI (4.999, 526.996)]. Conclusion:The administrative departments of CME should complete program evaluation regulations, adjust and perfect evaluation indexes based on research outcomes, emphasize on influential indexes of evaluation outcomes, and give full play of the guiding role of evaluation indexes.
ABSTRACT
Objective To investigate the value of the Changsha version of the Montreal Cognitive Assessment Scale (MoCA) in the assessment of vascular cognitive impairment after cerebral infarction .Methods 112 cases of clinically diagnosed cerebral infarc-tion were selected and divided into the normal cognition (NC) group and vascular cognitive impairment(VCI) group .The Changsha version of MoCA and the mini-mental state examination(MMSE) were adopted to detect the cognitive function ,the correlation of two scales was analyzed and the cutoff values of the Changsha version of MoCA were preliminarily studied .Results The total scores of the Changsha version of MoCA and MMSE in the VCI group were 15 .12 ± 4 .60 and 20 .44 ± 3 .22 respectively ,which were lower than 22 .75 ± 1 .79 and 25 .21 ± 1 .74 in the NC group ,the difference had statistical significance (P< 0 .05);the total scores of the Changsha version of MoCA was positively correlated with the total scores of MMSE (r=0 .84 ,P<0 .01);the best cut-off value of the Changsha version of MoCA was 20/21 ,the sensitivity and specificity were 92% and 95% respectively .Conclusion The Changsha version of MoCA can screen VCI well and has a high screening value ,and its optimal cutoff value is 20/21 .
ABSTRACT
OBJECTIVE: At present the function of Fas and Bcl-2 gene in the pathogenesis of myasthenia gravis has gained more attention and more studies have been extensively made inside and outside, to investigate the modulation of Fas and Bcl-2 gene expression is of extremely significance for exploring the pathogenesis and treatment of myasthenia gravis.DATA SOURCE: The related articles published in English from January 1990 to December 2004 were computer searched in Medline database using the terms of "Fas", "Bcl-2", "Myasthenia Gravis" and "gene".STUDY SELECTION: The data were identified preliminarily and literatures on the relationship between Fas and Bcl-2 gene and myasthenia gravis, as well as on Fas and Bcl-2 gene and genotherapy were remained for searching the full content.DATA EXTRACTION: A great deal of literatures about Fas and Bcl-2 gene were searched, 21 of which were studies on Fas and Bcl-2 gene and myasthenia gravis, and 32 on myasthenia gravis related genotherapy. A total of 20 representative articles were selected for analysis in this study.DATA SYNTHESIS: Eight out of 20 literatures were about the relationship between Fas gene and myasthenia gravis, 5 about the Bcl-2 gene and myasthenia gravis, 7 about the genotherapy in the treatment of myasthenia gravis and immune diseases.CONCLUSION: Abnormal Fas and Bcl-2 gene modulation and uncontrollable expression were closely associated with apoptosis defect of T lymphocyte and thymocytes, and even closely related to the pathogenesis of myasthenia gravis. To explore pathogenesis of myasthenia gravis at gene level by inducing cell apoptosis and depressing self-antibody production, would provide new means for the treatment of myasthenia gravis.
ABSTRACT
Objective To investigate the change and its clinical significance of serum erythropoietin(EPO) content in the patients with acute cerebral stroke.Methods The serum EPO content in 60 patients with acute cerebral infarction(ACI),45 patients with cerebral hemorrhage(CH) and 40 patients with other nervous system diseases(control group) were detected by radio-immunity means.The patients with acute cerebral stroke were evaluated by National Institute of Health Stroke Scale(NIHSS).Results The serum EPO content in ACI group and CH group [(1.64?0.41)ng/ml,(1.59?0.54)ng/ml] were significant higher than that in the control group [(1.17?0.86)ng/ml](all P
ABSTRACT
Objective To explore the changes of serum sFas levels and its clinical significance in patients with myasthenia gravis(MG).Methods T cell subsets and sFas levels in serum of 45 MG patients and 40 controls were measured by using flow cytometry and enzyme-linked immunosorbent assay each.Besides,the sFas levels variety of 24 MG patients using glucocorticoid(GC) were observed.Results(1) The percentage of CD~+_8T cells was much decreased in MG group[(21.50?2.21)%] compared with control group[(27.75?3.00)%]((P
