ABSTRACT
Objective To compare the effectivenessbetween the use of computer simulationin the teaching of abdomen diagnosis skills and the traditional teaching mode by conducting the real－time assessment and after－school questionnaire survey. Method Weselected 308 undergraduates with 165 (4 classes) majoring in clinical medicine and 143 (4 classes) majoring in medical laboratory in Kunming Medical Universityas the research object. Students were randomly divided into two groups and taught using demonstration method. One group practiced abdominal examination on other students while the other group adopted computer simulation.Both groups were giventests of practical skills and anonymous open－ended questionnaires after class.Results The average score of computer simulation group was higher than the other group. The questionnaire survey showed that computer simulation was suitable for repeatable exercises and easy to review after class (P＜0.05).Conclusion In thediagnostic practice of abdominal examination,teaching assisted with computer simulation showing an outstanding performance should be combined and promoted with the traditional teaching.
ABSTRACT
Cell transdifferentiation is the direct conversion of one type of cell into another without becoming a pluripotent stem cell. Rapid progress in this field has brought new perspectives on understanding and treating disorders associated with the nervous system,such as neurodegeneration, traumatic injuries,and neuropsychiatric diseases.Being able to obtain functional neurons through trans-differentiation from abundant somatic cells also provides a new strategy for regenerative medicine. In this review we highlight the recent progress in cell transdifferentiation for neurological disorders and dis-cuss potential challenges facing its clinical applications.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluated the fundamental role of stage control technology (SCT) on the detectability for Salmonella networking laboratories.</p><p><b>METHODS</b>Appropriate Salmonella detection methods after key point control being evaluated, were establishment and optimized. Our training and evaluation networking laboratories participated in the World Health Organization-Global Salmonella Surveillance Project (WHO-GSS) and China-U.S. Collaborative Program on Emerging and Re-emerging infectious diseases Project (GFN) in Shanghai. Staff members from the Yunnan Yuxi city Center for Disease Control and Prevention were trained on Salmonella isolation from diarrhea specimens. Data on annual Salmonella positive rates was collected from the provincial-level monitoring sites to be part of the GSS and GFN projects from 2006 to 2012.</p><p><b>RESULTS</b>The methodology was designed based on the conventional detection procedure of Salmonella which involved the processes as enrichment, isolation, species identification and sero-typing. These methods were simultaneously used to satisfy the sensitivity requirements on non-typhoid Salmonella detection for networking laboratories. Public Health Laboratories in Shanghai had developed from 5 in 2006 to 9 in 2011, and Clinical laboratories from 8 to 22. Number of clinical isolates, including typhoid and non-typhoid Salmonella increased from 196 in 2006 to 1442 in 2011. The positive rate of Salmonella isolated from the clinical diarrhea cases was 2.4% in Yuxi county, in 2012. At present, three other provincial monitoring sites were using the SBG technique as selectivity enrichment broth for Salmonella isolation, with Shanghai having the most stable positive baseline.</p><p><b>CONCLUSION</b>The method of SCT was proved the premise of the network laboratory construction. Based on this, the improvement of precise phenotypic identification and molecular typing capabilities could reach the level equivalent to the national networking laboratory.</p>
