RESUMO
Objective:To explore the application of English for medical purpose (EMP) in integrated medical education for medical undergraduates.Methods:A total of 120 undergraduates who participated in the integrated medical education in Chongqing Medical University were divided into EMP group and traditional medical English teaching group. There was no difference in the syllabus knowledge between the two groups. The teaching method of EMP group combined with integrated medical education and gave medical English teaching according to the organ system. The traditional group conducted the teaching according to the traditional medical English teaching method based on word formation and sentence understanding. SPSS 24.0 was used for t-test. Results:The scores of medical vocabulary test in the EMP teaching group were higher than those in the traditional teaching group [(85.00±3.52) vs. (65.67±3.33)]. The number of Review papers published in EMP group was 14, while 6 in traditional teaching group. The teachers used a randomized double-blind method to score the students' review papers (total score was 100 points). The results showed that the score of properly using medical vocabulary of students in the EMP teaching group were higher than those in the traditional teaching group [(84.52±2.34) vs. (70.98±1.45)]. The scientific evaluation score on review content in EMP group was higher than that in traditional teaching group [(88.87± 4.68) vs. (71.87±2.41)]. The grammar score of EMP group was higher than that of traditional teaching group [(90.01±7.24) vs. (76.00±3.76)].Conclusion:Medical English EMP course can better cooperate with the integrated education for medical undergraduates, improve students' ability of using medical English to retrieve literature and understand medical English according to organ system.
RESUMO
A headspace gas chromatography method was developed for the determination of six residual solvents including methanol, ethanol, acetone, dichloromethane, tetrahydrofuran and toluene residues in selexipag to provide the experimental basis for its quality control.The samples were separated on Kromat PC-624(V)silica capillary column(30.0 m ×0.32 mm,1.8 μm)using temperature programming.The column temperature was kept at 40 ℃ for 5 min initially,and then raised to 180 ℃ at the rate of 20 ℃ /min and subsequently sustained for 5 min.FID detector temperature was 250 ℃ and injection temperature was 200 ℃.The split ratio was 20 : 1. The six residual solvents are separated completely under the given chromatographic conditions with a good linearity (r=0.998 2-1.000);the results of precision,repeatability and stability experiments met the requirement,and the mean recoveries of all solvents were in the range of 96.67％-101.7％.The analytical method is simple,accurate and sensitive,and it can be used for the determination of residual solvents in selexipag.
