Matrix-assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI-TOF MS) is one of the preferred detection techniques for identification of clinical microorganisms and it has the characteristics of rapid identification, simple operation, low cost, and updatable databases. For laboratory medicine undergraduates, clinical internship is an important stage for the connection of basic theoretical knowledge and clinical practice. Internship teaching choosing MALDI-TOF MS as the content will greatly increase the popularity and applicability of the new technology in the clinical microbiology laboratory.
With the help of electronic databases on the network, we conducted a systematic review. According to the purpose of research, we singled out forty papers. Latest studies on history, basic principles, clinical features, and applications of MALDI-TOF MS and the internship teaching contents introducing new technologies are summarized and focused on. In internship teaching, firstly we explain the historical development, basic principle and widespread applications of MALDI-TOF MS in the identification of clinical pathogenic microorganisms and the detection of antibiotic resistance. Subsequently, we instruct the students to perform the experimental operations, analyze the common problems, and find solutions. Finally, we highlight quality control and laboratory biosafety.
Most of the reviews published previously report the clinical features and applications of MALDI-TOF MS and the internship teaching contents choosing other new technologies. It is the first study selecting MALDI-TOF MS technology as an internship teaching content creatively. Primary outcome is that the students understand the theoretical knowledge in detail, master the operation skills of MALDI-TOF MS quickly, and obtain excellent internship performances in the clinical internship through the internship teaching. Secondary outcome is that it is a help to cultivate medical students' train of thought for scientific research and to understand the application of the new technology in clinical testing and scientific research.
Laboratory medicine undergraduates should cherish the opportunity to learn the new technology during the internship period and should master basic principle and operation. As internship teachers, it is necessary to introduce the new technology to students during the internship and encourage undergraduates to cultivate creative and innovative thinking of scientific research.
基质辅助激光解吸电离飞行时间质谱(MALDI-TOF MS)是临床微生物鉴定的首选检测技术之一,具有鉴定快速、操作简单、成本低廉以及数据库可更新等特点。对于医学检验专业本科生而言,临床实习是基础理论知识与临床实践相衔接的重要阶段。选择MALDI-TOF MS作为实习教学内容,将极大提高该新技术在临床微生物实验室的普及程度和应用能力。
借助网络电子数据库进行系统综述。依据研究目的筛选出40篇论文,总结并重点关注MALDI-TOF MS的历史、基本原理、临床特点、应用以及引入新技术的实习教学内容。在实习教学中,首先讲解MALDI-TOF MS在临床致病微生物鉴定及抗生素耐药性检测中的历史发展、基本原理和广泛应用;随后指导学生进行实验操作,分析常见问题并寻找解决方案;最后强调质量控制和实验室生物安全。
既往发表的多数综述报道了MALDI-TOF MS的临床特点及应用,以及选择其他新技术的实习教学内容。本研究首次创新性地选择MALDI-TOF MS技术作为实习教学内容。主要结果是,通过实习教学,学生详细理解了理论知识,快速掌握了MALDI-TOF MS的操作技能,并在临床实习中取得了优异的实习成绩。次要结果是,有助于培养医学生的科研思路,使其了解新技术在临床检测和科研中的应用。
医学检验专业本科生在实习期间应珍惜学习新技术的机会,掌握其基本原理和操作方法。作为实习带教教师,有必要在实习期间向学生介绍新技术,鼓励本科生培养科研创新思维。
