An integrated and projected-based laboratory course was described, integrating interconnected knowledge points and biochemistry and molecular biology techniques on a research project-based system. The program, which served as an essential extension of theoretical courses to practice, was conducted with a sophomore of basic medical science who had completed the course in medical biochemistry and molecular biology. This course engaged students in learning "genetic manipulation" and "recombinant DNA technology" to understand the target gene's role in disease mechanics, thus altering evaluation and treatment for clinical disease. Students could master applied and advanced techniques, such as cell culture, transfection, inducing exogenous fusion protein expression, purifying protein and its concentration assay, quantitative polymerase chain reaction, and western bot analysis. This laboratory exercise links laboratory practices with the methods of current basic research. Students need to complete the experimental design report and laboratory report, which could be advantageous for improving their ability to write lab summaries and scientific papers in the future. The reliability and validity analyses were conducted on the questionnaire, and we examined students' satisfaction with the course and their gains from the course. The student feedback was generally positive, indicating that the exercise helped consolidate theoretical knowledge, increase scientific research enthusiasm, and provide a powerful tool to be a better person and make informed decisions.
本文描述了一门基于项目的综合性实验课程,该课程在基于研究项目的系统上整合了相互关联的知识点以及生物化学和分子生物学技术。该项目作为理论课程向实践的重要延伸,面向已完成医学生物化学与分子生物学课程的基础医学专业大二学生开展。本课程让学生学习“基因操作”和“重组DNA技术”,以了解目标基因在疾病机制中的作用,从而改变临床疾病的评估和治疗方法。学生能够掌握细胞培养、转染、诱导外源融合蛋白表达、蛋白质纯化及其浓度测定、定量聚合酶链反应和蛋白质免疫印迹分析等应用技术和先进技术。该实验练习将实验室实践与当前基础研究方法联系起来。学生需要完成实验设计报告和实验室报告,这有助于提高他们未来撰写实验总结和科研论文的能力。我们对问卷进行了信效度分析,并考察了学生对该课程的满意度以及他们从课程中的收获。学生反馈总体积极,表明该练习有助于巩固理论知识、提高科研热情,并为成为更好的人及做出明智决策提供有力工具。
