How to select and organize the content of course is an important component in curriculum reform. The special part for medicine in medical physics has characteristics of medical college, and is essential. The integration of this part is difficulty in curriculum reform of medical physics. In detail, the corresponding part of physics for medicine is integrated into a topic, which followed the part of classical physics. We adopted the method of special-topic teaching. Based on teaching experiences and in combination with the practical condition of the medical college, this paper selects and recombines some course content for medicine from medical physics, which is adopted by five-year medical students. Furthermore, some teaching requirement and guidance suggestion are presented.

This paper deals with the program for the course content concordance of medical physics for the five-year medical students based on the course theory,in combination with the practical condition of the medical college,and by means of the study of course theory,course objectives and the textbook.

OBJECTIVEThrough the comparison of Xiaoyu ointment and xiaoyu plaster by in vitro transdermal demonstrate, to demonstrate the scientificity and feasibility of reformed formulation.

METHODThe improved Franz diffusion cells and in vitro rabbit skin were used in vitro penetration experiment with emodin as an indicator of penetration rate quantitated by HPLC.

RESULTThe cumulative penetration rate of emodin in Xiaoyu ointment fit the model of Weibull distribution, while the cumulative penetration rate of emodin in Xiaoyu plaster fit the model of Density equation. Take emodin as an index,the transdermal rate in Xiaoyu plaster was 1.93 times as Xiaoyu ointment, and the total penetrated amount was 2.84 times as Xiaoyu ointment. The results showed that the emodin of xiaoyu plaster reserved in the skin were 3.95 times more than the ointment.

CONCLUSIONThe penetration rate, total penetrated amount and the reserves in the skin of Xiaoyu plaster were better than the ointment, and the transdermal dosage form was better than the original form.
