Abstract: Artemisia argyi is a well-known medicinal plant which has been used in traditional Chinese medicine for thousands of years. It is usually named Aicao or Aihao in China, and the leaves are processed and applied in moxibustion to treat different kinds of diseases. In order to select the best germplasm resource to grow high quality herbal products, we have compared the HPLC fingerprints profiles of 52 geographically different germplasm resources collected from 17 provinces of China. The results data were processed by similarity and hierarchical clustering analyses. In addition, common patterns of a typical local variety of A. argyi sourced in Henan province are established, and sample similarities were evaluated by selection of 14 typical chromatographic peaks of 10 samples and are found to vary between 0.664 and 0.969. The results show that the HPLC fngerprint analysis and quantitative analysis is a powerful tool to identify and control the quality of fresh A. argyi and related products. In addition, the content of a major secondary metabolite in the leaves of A. argyi known as eupatilin, which is a flavone with numerous bioactivities such as anticancer, anti-inflammation and anti ulcer has been determined for all the 52 samples by HPLC-DAD. The results provided great scientific basis for the research and development of the herb as popular products for the health care of human beings.

Abstract: Internal medicine plays a critical role in the curriculum system of traditional Chinese medicine (TCM) universities, which is the main course in TCM colleges and the professional knowledge must be mastered by medical students. However, due to the immense contents and concepts in internal medicine, the traditional lecture-based learning (LBL) led to dissatisfactory education effects. The purpose of the study is to explore the application of hybrid case-based learning (CBL) + team-based learning (TBL) method in educational practice of internal medicine in TCM universities. The undergraduates majoring in Chinese medicine of grade 2014, 2015 and 2016 from Beijing University of Chinese Medicine (BUCM) were enrolled. Students of grade 2014 were utilized as the control group, adopting traditional teaching method. Students of grade 2015 and 2016 were employed as the experimental groups, using the hybrid CBL+TBL teaching method. At the end of the internal medicine curriculum, the teaching resultant was evaluated by both theoretical test and skill assessment. The results demonstrated that experimental groups scored better than control group in both theory and clinical examinations, and the discrepancies were significant, respectively. The introduction of hybrid CBL+TBL teaching method into education of internal medicine in TCM universities promoted students’ ability of self-learning and sense of teamwork, so as improved the teaching effectiveness of clinical courses.
