Implementation of web-based PBL teaching mode in medical education and case studies / 中华医学教育探索杂志

Due to the subjective and objective constraints of universities in China,PBL Teaching Mode failed to gain its popularity in China's medical education.In its teaching reform,Guangzhou Medical University put forward a new teaching model--Web-based PBL Teaching Mode(hereinafter referred to as WPBL).by integrating the classical concept of PBL education with the real situation of the university and carried it out among students in bilingual classes of Clinical Medicine.The resuIts showed that by effectively overcoming the difficulties during the implementation of classical PBL teaching,Web-based PBL Teaching Mode not only succeeded in achieving the teaching objectives,but also improved the learning efficiency and utilization of teaching resources greatly by means of network technology.

Evaluation method about the learning effect of web-based PBL with key factors simulation / 中华医学教育探索杂志

Objective This paper aims to use components as the key factors to explore the feasibility of evaluation method about the learning effect of Web-based PBL.Methods We distributed a questionnaire to 101 students of clinical class of 2007 and 2008 grade in Guangzhou Medical University,and electronically distributed after 2 weeks.Cranach's α coefficient WaS used to evaluate intrinsic consistency reliability of the questionnaire.We applied principal axis factoring to extract components and to explain components which were orthogonally rotated by varimax.Multi-factor regression model Was simulated with key factors and the model's performance of fitting WaS tested.Results Multi-factor regression mode(WPBLSUM)=0.545 Collective collaboration capabilities+0.202 Self-learning and quest skills+0.137 linical reasoning and problem-solving capabilities+0.116 memorizing and understanding of medical knowledge.The coefficient of determination R2Was 0.998 and the corrected coefficient of determination R2Was 0.998.indicating that the model's fit results are obvious.Conclusion This paper demonstrates that using components as the key factors to simulate and assessing the Web-based PBL learning effect is feasible,which assesses the Web-based PBL learning effect well from four different aspects.

A prevalence survey on chronic pharyngitis in residents of Dongfeng town, Zhongshan city,Guangdong / 中华全科医师杂志

Personal health records were collected and analyzed for 1804 residents at Dongfeng town,Zhongshan city, Guangdong. One hundred and forty-one of 1804 residents suffered from chronic pharyngitis with a prevalence of 7.8 percent, 11.9 percent in males and 6. 6 percent in females with statistically significant difference (x2 = 12. 076, P ＜ 0. 05 ). Age, body mass index, physical exercise, eating habit,dental caries, oral illness (gingivitis, periondontitis, ondontolith), ear-nose-throat diseases, allergic constitution all were associated with their chronic pharyngitis, which was more prevalent in those of males,with ear-nose-throat diseases, lack of physical exercise, aged less than 24 years and over-intake of sugar.

Smoking, Alcohol Drinking and Gallstone Disease in General Male Population / 中国慢性病预防与控制

Objective To explore the relationship between smoking, alcohol drinking and gallstone disease in general male population in Guangdong. Methods Each subject received a questionnaire and took an upper abdominal ultrasound examination in a cross-sectional study. Results The prevalence of gallstone disease became higher with the increase of amount of cigarette smoking per day (trend test ?2=5.542, P=0.019) and with the total amount of cigarette smoking in their life (trend test ?2=7.302, P=0.007), these significance remained after controlling well-known risk factors for gallstone disease such as age and body mass index (BMI) (OR=1.269,95%CI: 1.018~1.580 for cigarette smoking per day and OR=1.295, 95%CI: 1.020~1.646 for total ). Little to moderate alcohol drinking (
