ABSTRACT
Objective:To explore the application effect of task-driven teaching method combined with Sandwich teaching method in the standardized residency training of oral general practitioners.Methods:A total of 40 trainees of the standardized residency training of the Teaching and Research Section of Oral General Practice in Chongqing Medical University were randomly divided into experimental group and control group. The experimental group ( n=20) adopted task-driven teaching method combined Sandwich teaching method, and the control group ( n=20) adopted the traditional teaching method. The theory assessment, skills assessment and the teaching satisfaction questionnaire survey were conducted to evaluate the teaching effects. SPSS 19.0 software was used for t-test. Results:The theoretical test scores of the experimental group were significantly higher than those of the control group [(85.85±25.61) points vs. (74.35±10.53) points], and the difference between the two groups was statistically significant ( t=8.56, P < 0.001). The skill test scores of the experimental group were significantly higher than those of the control group [(86.50±18.20) points vs. (73.40±16.57) points], and the difference was statistically significant ( t=9.94, P<0.001). The results of the teaching satisfaction questionnaire showed that the experimental group had significantly higher scores than control group in such seven aspects as improving students autonomous learning ability and interest in learning, teamwork and interpersonal relationships, diagnostic ability of cases and the accuracy, doctor-patient expression and communication ability, ability to find and solve problems, stimulating interest in scientific research and teaching, mastering and understanding the oral theoretical knowledge and so on ( t=10.40, 10.40, 9.95, 5.43, 7.66, 8.08, 9.60, respectively, all P<0.001). Task-driven teaching combined with Sandwich teaching method stimulated the learning interest of trainees and improved their comprehensive ability. Conclusion:Task-driven teaching combined with Sandwich teaching method has greatly improved the teaching effect of standardized residency training of oral general practitioners.
ABSTRACT
Objective:To study the changes of endothelin-1(ET-1) and malondialdehyde (MDA) in Kawasaki disease (KD) and to probe the relationship between the changes of ET-1, MDA and coronary artery pathological changes. Methods: KD group included 42 patients ( male 25, female 17), with a mean age of (3.25?0.75) years old; control group included 30 normal children (male 19, female 11), with a mean age of (3.58?0.55) years old. Serum contents of ET-1 and MDA were measured by radioimmunology and modified thiabarbituricaid(TBA) method in 2 groups, and the inner diameters of coronary artery and aorta were measured by color echocardiography. KD group was subdivided into dilated-coronary artery group and undilated group for comparison.Results: Serum contents of ET-1 and MDA in KD group were apparently higher than those in control group (-[76.63?18.36-] vs -[41.55?16.68-] pg/ml and -[3.18?0.60-] vs -[1.52?0.24-] ?mol/L,respectively;P
