Objective:To explore the application and effect of team-based learning (TBL) combined with flipped classroom in the teaching of physiology.Methods:A total of 70 medical students were selected and randomly divided into two groups, experimental group ( n=34) and control group ( n=36). Both groups studied digestion physiology by different method. In the experimental group, the students were taught by TBL combined with flipped classroom. The control group was given traditional teaching. The students studied and discussed problems in a team, and shared the answers in the flipped classroom. The effects of teaching were evaluated by the final test scores and the self-made questionnaire. SPSS 17.0 was used for t test on data comparison between the two groups. Results:The test scores of digestion physiology in the experimental group were (5.47±1.02) points, which were significantly higher than those of the control group (4.42±1.63) points, with significant differences ( P=0.020). A total of 34 questionnaires were issued and 34 valid questionnaires were collected, with an effective rate of 100%. The questionnaire results showed that TBL combined with flipped classroom was accepted and approved by about 82% of students in the experimental group who agreed that the teaching model helps enhance students' initiative and interest in learning, develop their sense of cooperation and comprehensive application ability. Conclusion:TBL combined with flipped classroom is feasible and effective in the physiological teaching, and it can be popularized in medical courses.

Objective To investigate the effects of antioxidant response element (ARE) activator- 5,6-dihydrocyclopenta[ C ]-1,2-dithiole-3-thione (CPDT) on organotypic spinal cord cultures and to study whether this activation can protect motor neurons from oxidative stress.Methods Organotypic spinal cord cultures were prepared using lumbar spinal cord slices from 8-day-old rat.Threo-hydroxyaspartate (THA) was continuously added into the culture medium for 3 weeks,which caused selective motor neuron death. Thus,the in vitro model of amyotrophic Lateral sclerosis (ALS) was established.15,30 ?mol/L of CPDT were added into the culture medium respectively.Ventral motor neurons survival was evaluated by immunohistochemical staining with monoclonal antibody SMI-32,a nonphosphorylated neurofilament marker. Ultrastructure was observed with electronic microscope.Results The pretreatment of organotypic spinal cord cultures with different concentrations of CPDT significantly increase the total number of ventral motor neurons (15?mol/L:(15.81?6.97) perexplant;30?mol/L:(16.25?6.74) perexplant respectively) compared with THA group ((5.31?5.76) perexplant) and the former had plentiful neurite extensions (n= 15,P

Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma were widely used in strengthening spleen under different disease conditions, and were easily and often misused each other. Therefore, DNA barcode was used to distinguish Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma from their adulterants to ensure the safe use. The sequence lengths of ITS2 of Atractylodes macrocephala, Atractylodis Rhizoma (A. lancea, A. japonica and A. coreana) were both 229 bp. Among the ITS2 sequences of A. macrocephala, only one G/C transversion was detected at site 98, and the average GC content was 69.42%. No variable site was detected in the ITS2 sequences of A. lancea. The maximum K2P intraspecific genetic distances of both A. japonica and A. coreana were 0.013. The maximum K2P intraspecific genetic distances of A. macrocephala, A. lancea, A. japonica and A. coreana were less than the minimum interspecific genetic distance of adulterants. The ITS2 sequences in each of these polytypic species were separated into pairs of divergent clusters in the NJ tree. DNA barcoding could be used as a fast and accurate identification method to distinguish Atractylodis Macrocephalae Rhizoma, Atractylodis Rhizoma, from their adulterants to ensure its safe use.

This study was aimed to analyze differences of chemical compounds of Ginseng and Radix Puerariae be-fore and after compatibility using HPLC. Hypersil ODS column (4.6 mm × 250 mm, 5μm) was adopted. The mobile phase was acetonitrile-water for gradient elution. The detection wavelength was set at 203 nm. The column tem-perature was 25℃. The flow rate was 1 mL/min. The results showed that through the study of all main peaks in the finger print spectra, there was no obvious influence on extract before and after compatibility of Ginseng and Radix Puerariae. It was concluded that there were no obvious chemical changes of Ginseng and Radix Puerariae before and after compatibility. The synergistic mechanism of compatibility might mainly come from the interaction between the pharmacological actions and the absorption or the metabolism of effective constituents of the medicinal plants.

Objective To make students at different levels not only learn theoretical knowledge of acupuncture-moxibustion manipulation skills but also achieve full operating training, strengthen the combination of theory and practice and improve the teaching quality of clinical disciplines by applyingmultimedia-subject participationteaching method to acupuncture-moxibustion manipulation techniques in the experimental teaching of acupuncture and moxibustion. Method The students were randomized, according to grade, into experiment (n=114) and control (n=115) groups. The teaching content was the same in the two groups. The experiment group received multimedia-subject participationteaching method. After the multimedia teaching, the students did an independent demonstration and made a self-evaluation, the teachers made a comment and the students did independent practice again in groups. The control group received conventional theory teaching and did practice under demonstration in the experimental lesson. The examination and questionnaire were used as assessment indicators to evaluate the effect ofmultimedia-subject participationteaching method applied to acupuncture-moxibustion technique teaching. Result Statistical analysis was made using the SPSS11.5 statistical software package. The independent samples t-test is used for a between-groups comparison. The statistical result showed that satisfaction was 100%in the experiment group and 75.7%in the control group;there was a statistically significant difference between the two groups (P<0.05). Conclusion Multimedia-subject participationteaching method is an innovation in acupuncture-moxibustion technique teaching and helps the students to better master acupuncture-moxibustion manipulation skills. Mastery of theoretical knowledge before real practice is the key to proficient manipulation. The combination of the two in classroom teaching yields twice the result with half the effort. Carrying out multimedia-subject participation teaching method will help to further deepen the teaching reform and to improve the level and quality of“Acupuncture and Moxibustion”teaching.
