Objective:To investigate the role of service-learning model in medical ethics education. Meth-ods:A qualitative and quantitative research was conducted within 831 undergraduates and 302 graduates in Shan-tou University Medical College. Results: Service-learning model was well accepted by most medical students. Higher medical ethics awareness and more positive tendency of behavior choices were found on the group who par-ticipated in serving-learning model activities, which also revealed a positive correlation relationship to participated frequency. Conclusions:Serving-learning model plays an important role in medical ethics education, which is an effective way to deeply practice Opinions on Deepening the Medical and Educational Reform toward Personnel Training in Clinical Medicine.

Objective: To understand the characteristics of rapid naming in exotropia children, and to analyze the influence of clinical indicators related to exotropia on the rapid naming. Methods: A total of 45 exotropia children were recruited according to the diagnostic criteria of consensus of strabismus classification experts (2015) from the Zhongshan ophthalmic center as the case group, and 45 children of the same age, gender and parental educational status were recruited as the control group without any ocular diseases. All children were evaluated the ability of the rapid naming by classical rapid naming test. Results: The letter rapid naming time of children with exotropia was longer than that in control group [(26.87±10.18)(21.98±7.29)s], and the difference was statistically significant (t=2.73, P=0.01), however there was no significant correlation between strabismus degree, symptom duration, AC/A ratio, disease classification, simultaneous vision, the near stereopsis, the far stereopsis and the letter rapid naming in the clinical indicators of exotropia (r=-0.16, 0.23, 0.20, 0.06, 0.09, 0.05, 0.20, P>0.05). Conclusion Rapid naming might be impaired among children with exotropia, with no significant correlation between this defect and its clinical indicators.
