目的 促进医学生化检验课程理论与实验的结合，提高学生学习实验兴趣，增强学生临床对话的能力。 方法 通过创建问题情景和病例，在医学检验专业本科班中应用以问题为导向教学法（PBL），结合病例教学方法进行临床生化检验实验教学改革。 结果 问卷调查显示，学生在教学内容掌握、学习的主动性、综合分析能力、创新能力、团队协作等方面均得到明显提高。92.6%的学生认为PBL结合病例教学法优于传统实验教学法。 结论 PBL结合病例教学法值得在生化检验实验教学中加以推广。
This paper is to discuss the research of heterogeneity in Meta-analysis, including the definition of the heterogeneity in Meta-analysis and classification it into clinical heterogeneity, methodological heterogeneity and statistical heterogeneity, the strategies for diminishing clinical heterogeneity and methodological heterogeneity, the five testing methods in statistical heterogeneity (Q statistic, I2 statistic, H statistic, Galbraith plot and L’Abbe plot) and the examples and applying conditions of the five testing methods, classification of meta-analysis into exploratory meta-analysis and analytic meta-analysis according if the meta-analysis has heterogeneity, and the strategies and the flowchart when existing the heterogeneity in meta-analysis.
The teaching team of the Department of Laboratory Medicine, West China School of Medicine, Sichuan University takes scientific spirit, craftsmanship spirit, and medical humanities spirit as the goal, combines the core knowledge of clinical microbiology laboratory technology course with cases of coronavirus disease 2019 prevention and control, drug resistance monitoring, and scientists’ deeds, and adopts strategies such as hot debate and special report to achieve the integration of knowledge and value. The actual effectiveness of this model has been verified through the assessment of students’ abilities and values. This article introduces the course-based ideological and political education construction mentioned above, aiming to explore the integration path of course-based ideological and political education in the clinical microbiology laboratory technology, and construct a new teaching model that combines professional competence and value guidance.
Inappropriate and irrational prescription of antimicrobial agents has led to increasing bacterial resistance, which has become a major concern around the world. Clinical microbiology service provides a basis and guarantee for the rational application of antimicrobial agents and an important technical support for antimicrobial stewardship, and plays an important role in promoting the rational use of antimicrobial agents. This paper summarizes and evaluates the specific role and technical requirements of clinical microbiology service in the diagnosis of infectious diseases, rational application of antimicrobial agents, hospital infection control and training of medical staff, so as to provide a technical guidance for clinical microbiology service in the antimicrobial stewardship.
Real-time updates of metrical data can not generally be realized in the commonly used methods for calculating the pulse wave of blood oxygen saturation. Based on the hardware platform of pulse wave signal from NJL5501R, and high linear correlation of the red laser and infrared light collected in pulse wave signal measurement, an approach to determine the value of the blood oxygen saturation is proposed in the present paper by establishing the linear regression model of the red laser and infrared light. The effect of the sampling number of pulse wave signal in calculation on the characteristic parameters of pulse wave is also analyzed. The experimental results showed that the approach could guarantee the measuring accuracy and realize the fast updates of blood oxygen saturation data. This paper provides an effective method for real-time and accurate monitoring of pulse blood oxygen saturation in human body.
In view of the fact that medical inspection equipment sold in the domestic market is mainly imported from abroad and very expensive, we developed a full-automatic fluorescence analyzer in our center, presented in this paper. The present paper introduces the hardware architecture design of FPGA/DSP motion controlling card+PC+STM32 embedded micro processing unit, software system based on C# multi thread, design and implementation of double-unit communication in detail. By simplifying the hardware structure, selecting hardware legitimately and adopting control system software to object-oriented technology, we have improved the precision and velocity of the control system significantly. Finally, the performance test showed that the control system could meet the needs of automated fluorescence analyzer on the functionality, performance and cost.
With the dissemination and popularization of EBM around the world, the evidence-based laboratory medicine has boomed gradually. However, the substantial researches in tbe field are still inadequale now. Based on the facts of hospital laboratory medicine, this article discussed the feasibility that apply the rationale and methods to orient the laboratory quality control.
