RESUMEN
【Objective:】 To understand the current situation and influencing factors of ethical knowledge, attitude, and practice (KAP) among clinical researchers, enhance their ethical awareness, and improve the quality of clinical researches. 【Methods:】 A self-designed questionnaire was used to conduct a convenient sampling survey of medical staff who have participated in clinical study. 【Results:】 A total of 6,021 subjects were investigated, with males accounting for 28.46% and females accounting for 71.53%. The average age of them was (37.47±11.46) years old. The total score of ethics and the mean scores of the three dimensions of knowledge, attitude and practice were (70.62±12.99), (59.63±12.50), (79.55±19.62) and (74.92±18.29), respectively. Multiple linear regression analysis showed that researchers with male, tertiary hospitals, doctors, ethics-related part-time jobs, postgraduate education, associate senior title or above, and training experience scored higher (P<0.05). 【Conclusion:】 Ethical attitudes have a significant mediating effect between knowledge and practice, accounting for 62.72% of the total effect. Researchers recognize the importance of ethics, but it is urgent to strengthen their knowledge learning and practical application.

Based on practice of video-cases teaching,this paper put forwards four sorts of contradictions,which are the contradiction between time limitation of classroom and expressing limi-tation of video cases,the contradiction between relative independence of video cases (part)and con-sistency of teaching objective (entirety),the contradiction between apparentness of video cases (phe-nomenon)and depth of teaching content (essence)and the contradiction between variability of video case class and control of class by teachers. This paper suggested teaching principle of part conforming to entirety. Meanwhile,it indicated that classroom video case teaching should have strict design, closely coordinated class discussion and teachers should be good at guiding and summarizing. Through these efforts,the above four contradictions can be resolved and designed video case teaching obtained good effect.
RESUMEN
@#Objective To investigate the risk factors of cerebral palsy(CP)in children.Methods 1∶2 matched case-control study was carried out in 100 CP children and 200 controls individually matched for sex and age were selected for each case.The data were analyzed with Logistic regression.Results 9 risk factors were suggested from univariate analysis,namely hospital level,educational level of mother and father,premature birth,neonatal asphyxia,ABO hemolysis,lower birth weight,hypoxic-ischemic encephalopathy(HIE)and kernicterus.The risk factors confirmed by multivariate analysis were hospital level,educational level of father,premature birth,neonatal asphyxia,ABO hemolysis,lower birth weight and HIE.Conclusion Relevant risk factors of CP are various.
