Résumé
Objective To systematically review the effect of team-based learning (TBL) versus the traditional lecture-based learning (LBL) teaching model on basic medical courses in undergraduate medical education. Methods The CNKI, VIP and Wanfang medical databases were electronically searched to retrieve randomized controlled trial studies on TBL applied in undergraduate basic medi-cal courses up to June 2014. In these studies TBL teaching model was used in experiment group with LBL teaching model as control group and course grades were adopted to evaluate the effect of learn-ing. Literature screening, data extraction, and quality assessment were performed in strict accordance with the inclusion and exclusion criteria, and then data were analyzed using RevMan 5.3 software. Results This Meta-analysis examined 12 studies, all of them with low quality at C level. Meta analysis shows that the score of the course of TBL teaching is better than the traditional LBL teaching, and the difference is statistically significant [weighed mean difference (WMD): 9.33, 95%CI (5.67, 13.00), P=0.000]. Conclusion Compared with the LBL teaching, the application of TBL teaching in medical undergraduate basic medical courses has the promotion effect, but need more rigorously randomized controlled trials to verify.
Résumé
AIM: To establish the quality standard for Tongfeng Huadu Tincture (Radix Gentianae Macrophyllae, Radix Angelicae Pubescentis, Rhizoma Chuanxiong, Herba Asari, etc.). METHODS: The Radix Gentianae Macrophyllae, Radix Angelicae Pubescentis, Rhizoma Chuanxiong, Herba Asari of Tongfeng Huadu Tincture were identified by TLC. Strychnine of Tincture was determined by HPLC. RESULTS: The average recovery was 97.07% and RSD and 2.1% (n=5). CONCLUSION: The method is reliable, accurate and specific. It can be used for quality control of Tongfeng Huadu Tincture.
