Study on Tumor Drugs for Targeted Therapy Based on Micro-nanomotor / 中国药师

Objective:To investigate the targeted motion and controllable release of tumor drugs based on micromotor. Methods:The directional movement of Janus micro-capsules was achieved through an external magnetic field,and the controllable release of tumor drugs was induced by near-infrared laser.Results:During the same period, the movement speed of the Janus capsules micromotor was the fastest(36.8 μm·s-1,approximately equalled to 3 body length·s-1) in 15% H2O2solution. Under the control of the external magnetic field, the Janus capsules micromotor could move along the scheduled trajectory close to the area of HeLa cells. Through the irradiation of near-infrared laser, the Janus capsules micromotor was broken and released the loaded drugs quickly. Conclusion:The Janus capsule micromotor studied in the paper can be used for targeted drug delivery safely and effectively,therefore,it shows good application prospect in the field of tumor diagnosis and treatment.

The significance and prospects of clinical practice teaching in the influence of clinical skills competition / 中华医学教育探索杂志

Since participating in the clinical skills competition, the hospital has made consid-erable progress in the clinical practice teaching equipment, teachers, atmosphere and standards. This paper aims to explore the significance of competition to promote clinical practice teaching and sug-gests that under the existing conditions, we should improve the clinical skills curriculum and assess-ment, establish training standards, improve the level of clinical practice teaching, to give comprehen-sive support for cultivating excellent medical talents.

Exploration of humanities practice skill training for seven-year program clinical medicine students by teaching hospital / 中华医学教育探索杂志

Medical education should combine clinical professional skills with humanities skills,integrate humanities knowledge into vocational education.Taking 2008 grade seven-year program clinical medicine students in the 2nd affiliated hospital of Harbin Medical University as fostering object,we made researches into students' understanding of doctor-patient relationship before practice and their mastering of skills.Through conducting questionnaire,we got to know the effect of humanities practice skill training for seven-year program clinical medicine students.Meanwhile,we compared students' self evaluation results before and after training,discussed on how to improve medical students' communication skills,cultural skills and the reform direction in an aim to guide students to transit from students to clinical doctor.
