Objective To explore the short term and long term effectiveness of the problem-based learning (PBL) in clinical skill training. Methods A total of 162 clinical medicine undergraduates in Grade 2003 (7-years study) and 2004 (5-year study) who were supposed to intern in the internal medicine departments were randomly divided into the PBL group (n=75) and the control group with traditional training (n=87) for having their clinical skills training. Then t test was applied to compare the two groups about the scores of intern rotation examination and graduate OSCE as well. Results About the baseline: the students in the two groups got similar scores in their internal medicine exam before clinical intern rotation (84.04±7.40 vs. 82.63±8.77, P=0.287). About the short term effectiveness: compared to the control group, the students in the PBL group got higher subjective evaluation from their supervised clinicians (P=0.006). In writing examination, the students of those two group got similar scores in knowledge part (54.17±9.26 vs. 51.67±9.56, P=0.92), while the PBL group won in case reasoning question (20.39±5.27 vs. 16.51±4.90, Plt;0.001). About the long term effectiveness: in the graduate OSCE, the two groups got similar scores in skills operation such as punctures and lab results analyses (P=0.567 and P=0.741), while the students in the PBL group had better performance at the case reasoning and standard patients treating (75.59±9.85 vs. 71.11±12.01, P=0.027). Conclusion With the great short term and long term effectiveness, the PBL applied in the clinical skill training improves the students’ ability of both synthesized analyses and the integrated clinical skills such as clinical thinking and interpersonal communication, but doesn’t aim at the basic knowledge and operation skills.
诊断学是临床医学的基础和入门，是习得临床执业风格最重要的环节。如何在诊断学学习阶段，夯实学生基本理论和技能，培养其科学缜密的临床思维能力，是各医学院校共同面对的课题和挑战。互动参与式教学摒弃传统单一的被动式、灌输式的教学模式，强调以学生为主体，赋予学生协作性、参与性的教学诉求，加强内在激励，激发其主观能动性和创造力。根据诊断学不同教学模块的课程目标、内容和知识结构，有机地将互动参与式教学法应用于诊断学教学中：问诊-角色扮演，查体-示教与实践学习，症状学-小讲课、小组讨论、床旁实践，临床思维-案例分析，职业素养-小组讨论、角色扮演、床旁实践、辩论演讲等。策略得当地将互动参与式教学的理念、元素、方法应用于诊断学教学中，符合临床医学教学实践性强的特点，遵循个体认知规律，符合外部和内在发展并重的教学效果的深层考量，具备良好的教学容量和一定的普适性，值得在临床医学教学中推广运用。
Objective To explore teaching effects of case-based learning (CBL) in abdominal physical examination in diagnostics. Methods Among 83 undergraduates in grade 2007 and in major of 8-year clinical medicine were randomly divided into two groups. Under the same conditions, 41 in the CBL group were taught with CBL method, while the other 42 in the control group were taught with traditional teaching method. Their scores in standard patient (SP) practice assessment of abdominal physical examination, examination of abnormal abdominal signs, ability to analyze and write medical records, and right answers to abdominal examination in final exam were compared. Meanwhile, questionnaire surveys were distributed to them after class. Results There was no significant difference between the two groups in the scores of SP practice assessment or medical record writing and analyzing, but the CBL group was obviously superior to the control group in the tests of abnormal abdominal signs and the right answers to abdominal examination in final exam (Plt;0.05). The questionnaire surveys revealed that the CBL group obviously scored higher in the following 3 items: increase the learning interest and commitment, strengthen the ability to analyze and solve problems, and improve the ability to combine theory and practice (Plt;0.05). Conclusion CBL method has an obvious advantage to improve the teaching quality in abdominal physical examination in diagnostics.
目的 探讨诊断学床旁见习教学中学患关系现状，为提高诊断学床旁教学质量提供应对策略。 方法 采用自行设计问卷，于2010年5月-2011年6月对80名临床医学专业三年级本科生以及同期在内科住院的100例患者分别进行不署名学患关系问卷调查（有效问卷率分别为91.3%和67%），同时对8名带教教师和7名临床主管医生进行个别访谈。 结果 学生问卷调查显示，79.5%的学生曾在床旁教学中遭遇患者不同程度的拒绝或不配合，大多数学生认为有被拒的心理准备和承受力。患者调查显示，82.1%的患者不愿意接受学生问诊查体，58.2%的患者表示即便给予一定经济补偿，也不愿配合教学。而对带教教师及临床主管医师访谈结果显示，当前床旁带教难度大大增加，学患关系紧张。 结论 现阶段学患关系紧张，根据其涉及原因，提出提升医务人员及医学生人文观念，推进医疗、教育体制改革，建立媒体监督机制，开展公众教育等多层面的应对策略，同时提出课程设置、教学模式、师资培养等具体教学应对举措。Objective To explore the present status of the relationship between students and patients in diagnostic bedside teaching, in order to promote the teaching quality. Methods From May 2010 to June 2011, self-made questionnaires were adopted to carry out an anonymous survey among 80 medical students in grade three or above and 100 inpatients to investigate the relationship between the students and the patients(with an effective questionnaire rate of 91.3% and 67% respectively). Eight tutors and 7 physicians concerned were taken in the individual interview. Results The survey showed that 79.5% of the students encountered refusal from patients in bedside teaching, and most of them believed that they had psychological preparation and endurance for the refusal. A total of 82.1% of the patients expressed their unwillingness to accept examination by clinical students, and 58.2% of the patients were unwilling to cooperate in the teaching even with an amount of economic compensation. The tutors and physicians concerned stated that the student-patient relationship was undesirable at present. Conclusions The relationship between students and patients in bedside teaching is strained at present. Based on the complicated reasons, we propose such coping strategies as promoting humanism among medical workers and students, pushing forward the medical and educational reform, building media supervision, developing public education, perfecting course design, teaching style, and cultivation of teachers, and so on.
Objective To explore the teaching effects of problem-based learning (PBL) in diagnostic practice teaching. Methods A total of 32 students enrolled into PBL group adopted the PBL teaching method based on certain cases in some sections while the other 210 students into the control group adopted the traditional teaching method. Their scores in the theory, the practice skill examination and the evaluation of the analytical ability of the medical records were compared. A questionnaire survey was measured in PBL group after class. Results There was no significant difference in scores of theory and practice skill examination in the two groups. The questionnaire survey revealed that the PBL method could improve the learning interest, independent study, b communication, analytical skills, and team spirit. However, there were defects in systematization of imparting knowledge. Conclusion The PBL method has an obvious advantage in diagnostic practice teaching.
To cultivated competent clinicians with the potential to be future pillars and leaders is the educational objective of an 8-year medical program at the West China School of Medicine, Sichuan University. Problem-based learning (PBL) is more effective than traditional, passive, didactic teaching in training of communication skills, information management and critical thinking and research. These are included in the Global Minimum Essential Requirements in Medical Education (GMER). We introduce our practice of PBL as a separate course for the 8-year medical program, including its design, preparation, implementation and evaluation. We discuss why it is designed as a separate course and implemented in multiple semesters with fewer cases in each semester. The move from giving a fish to people to teaching people how to fish, and from teacher-centered to student-centered teaching is a radical transformation of educational concepts and the traditional teaching-and-learning model. Such a change cannot happen in a single step and we hope that this model PBL course, focusing on training in methods and skills, will facilitate the concept transformation and the involvement of all our teachers and students. This should help our teaching to evolve continuously, develop a system for evaluating PBL and lead to the gradual incorporation of PBL into our discipline-based courses or organ system-based courses.

ObjectiveTo evaluate the teaching effect of Patient based Problem-Based Learning (PPBL) vs. conventional bedside teaching (CBT) instudents of eight years medical program. MethodSix students of Eight years medical program in two grades from volunteer registration were randomized into PPBL group and the other students were recruited into CBT group. After one year study, the test score in module TBL test, written test in final exam and mutual score were evaluated to compare the teaching effect of two groups. ResultsThe baseline of the two groups were matched when comparing their grades in Diagnoses Course. After trainee period, there were no significant differences between two groups of the test score in module TBL test, written test in final exam and mutual score. ConclusionThe PPBL mode is not inferior to conventional bedside teaching. Furthermore, with advantage in developing the competency of communication, cooperation and manage the information, PPBL has its special value and should be popularized.
Objective To compare the survey results of the 8-year program students of clinical medicine discipline before and after the implementation of system-based integrated course reform, to provide feedback for system-based integrated course reform. Methods The questionnaire survey was continuously conducted for 2 years among the 8-year program students in grade of 2005 and 2006, so as to investigate their attitudes towards the integrated clinical courses, then relevant improvement of teaching measures were performed according to their feedback, and the difference of teaching effects between those 2 years was finally compared. Results A total of 79 students in grade 2005 and 78 students in grade 2006 were investigated. The baseline data were matched between the 2 grades. The results of statistical analysis showed that, the overall cognition (χ2=32.924, Plt;0.000 1) and assessment (t=−2.900, P=0.004) of integrated courses among students in grade 2006 got more improved in comparison with the students in grade 2005, and more students tended to select integrated courses, but there was no statistical difference. Conclusion Although system-based integrated clinical course as a new thing has its limitations, the reform idea and direction are still approved by students, so it is worth popularizing.
Objective To observe the fundus characteristics of human immunodeficiency virus with acquired immune deficiency (HIV/AIDS). Methods A total of 1041 HIV/AIDS patients were enrolled in this study. The patients included 882 males (88.70%) and 159 females (11.30%). The patientsprime; ages ranged from 12 to 73 years, with a mean age of 41 years. The median time of HIV/AIDS diagnosis was 12 months, which ranged from one month to 10 years. HIV infection was acquired through sexual contact, intravenous drug use, blood transfusion or mother-to-child transmission in 475 patients (45.63%), 508 patients (48.80%), 44 patients (4.25%) and 14 patients (1.34%), respectively. Ocular examinations (vision acuity, slit lamp microscope and fundus examination) were performed on recruited patients with HIV/AIDS. Additional exams (intraocular pressure, fundus photography and fundus fluorescein angiography) were done if abnormal ocular fundus was found. The ocular manifestations were diagnosed according to clinic reference. Results Ocular manifestations of HIV/AIDS were detected in 247 patients (23.73%). Of 247 patients, the most common ocular manifestation was HIV retinopathy, which was present in 132 patients (53.44%); cytomegalovirus retinitis (CMVR) was second place, affecting 70 participants (28.34%). Clinic findings of HIV retinopathy included retina microaneurysm, hemorrhage along the blood vessel with cotton-wool spots, while irregular dry edge, granular appearing border, were present in CMVR, and the optic nerve may be affected. Fluorescein angiogram of HIV retinopathy demonstrated that hemorrhage was shown as sheltered fluorescence, with b fluorescence without leakage in center of hemorrhage. Fluorescein angiogram of CMVR demonstrated significant hemorrhage appearing as sheltered fluorescence with leakage and/or transparent fluorescence. The optic disk and lesioned area were stained with fluorescence. Conclusions There are various HIV/AIDS related ocular manifestation. HIV retinopathy and CMVR are common ocular manifestations. The main clinical findings of HIV retinopathy are hemorrhage and/or cotton-wool spots, while irregular granular appearing edges and hemorrhage were observed in CMVR.
