Application of Flipped Classroom in postgraduate molecular biology technology teaching / 中华医学教育探索杂志

Techniques in Molecular Biology is an essential course designed for postgraduates majoring in medicine,biology and other related disciplines.We discussed here the significance of redesigning and the practical attempt,which specifically was the flip classroom model of research-based experimental course dominated by postgraduates.In this teaching model,according to the procedure of research work,postgraduates studied the experiment principle,read kit manual and selected controls before class.In the class,students in groups performed experiments and analyzed the experimental results.The teacher led students' technical operation to achieve the teaching targets and emphasized the evaluation for students' abilities of experimental design and results analysis.Online platform was maintained even after the course in order to achieve long-term academic communication.

Effects of comprehensive yoga intervention program on cardiopulmonary function and physical fitness among female college students / 中国学校卫生

Objective@#To explore the effect of comprehensive yoga intervention program on cardiopulmonary function and physical fitness among female college students.@*Methods@#Twohundred and forty female college students were invited to participate in the program and were randomly divided into intervention (n=120) and control group (n=120) by random number table method. The intervention group received regular yoga exercise, while the control group had no exercise intervention. Body shape, cardiopulmonary function, body flexibility, muscle strength and mental health of the two groups were compared before and after intervention.@*Results@#The cardiopulmonary function indices except PP of the intervention group improved significantly after intervention. There were no significant changes in cardiopulmonary function before and after the intervention for control group. The HR values of the observation group were significantly lower, and the values of SV, CO, VC, MVV and FEV1/FEV were significantly higher compared with those of the control group(P<0.05). Body mass index(BMI), waisttohip ratio and body fat percentage of observation group were significantly lower than that of control group(P<0.05). The performance on the sitandreach and situp test of observation group were significantly improved after intervention and were significantly higher than the control group(P<0.05). Somatization, sensitivity, depression and anxiety in the observation group decreased significantly after intervention and were lower than that of the control group(P<0.05).@*Conclusion@#The comprehensive yoga intervention program can effectively improve body shape, body flexibility and muscle strength, as well as improve cardiopulmonary function. It also plays a key role in improving mental health among female college students.
