ABSTRACT
In China， the incidence of ischemic heart disease （IHD） is increasing year by year， which brings enormous burden to families and society. It is urgent to find preferable treatment methods and medical therapies. The Chinese ethnic minority medicine has gradually developed unique theoretical systems and therapeutic characteristics on the basis of clinical experience and thinking modes including image-number thinking and the holistic perspective. Consequently， it possesses huge application capacity and research value in prevention and treatment of IHD. Belonging to the medical system based on the view of nature and life， the Tibetan medicine， Mongolian medicine， and Dai medicine have respectively formed theories like "three elements" "three life-sustaining energies" "four elements and five skandhas （aggregates）" ， have put forward unique understandings of IHD and have formed corresponding therapeutic principles and methods， generating plentiful classic prescriptions represented by Sanwei Tanxiang powder， Bawei Chenxiang powder， Roukou Wuwei pills and Yajiao Hadun powder. They also contain characteristic ethnic medicine resources such as Choerospondiatis Fructus， Rhodiola Rosea and Draconis Sanguis. Aiming to provide enlightenment and reference for the clinical application and development of the Chinese ethnic minority medicine for the prevention and treatment of IHD， the authors try to summarize the related researches represented by Tibetan and Mongolian medicines， and then discuss the opportunities and challenges faced by such researches.
ABSTRACT
The suitable production area can guarantee the quality of Dai medicine， but the research on the suitable ecological factors and suitable production area of plant Dai medicine is relatively scarce at present. In this study， gmpgis was used to analyze the ecological suitability of Dai medicine in China. For the first time， the range of ecological factors and main soil types in the main distribution areas of Dai medicine were extracted， such as annual average temperature of 8.6-23.7 ℃， annual average precipitation of 1212-1881 mm， annual average sunshine of 149.7-157.4 W·m-2， the main soil types are strong eluvial soil， alluvial soil， high activity strong acid soil， etc. Based on 179 sampling points， through the analysis of ecological similarity， the largest ecological similarity area of plant Dai medicine in the world was obtained， mainly including China， Brazil， the United States， Myanmar， Laos and other countries. In China， it is mainly concentrated in the West and south of Yunnan， including Xishuangbanna Dai Autonomous Prefecture， Dehong Dai Jingpo Autonomous Prefecture， Pu'er City， Baoshan City and Lincang City， which are suitable for cultivation. In addition， by analyzing the current situation of Dai medicine industry， this paper summarizes the problems such as the lack of talents， the decreasing of Dai medicine resources， the limitation of cultural heritage， and the weakness of scientific research， and puts forward strategies such as training high-quality talents of Dai medicine， the investigation and protection of Dai medicine resources， promoting the collection and arrangement of Dai medicine data and ancient books， and strengthening the basic and applied research of Dai medicine Enter the development of Dai medicine. This study provides a basis for guiding the rational layout， introduction and breeding of plant Dai medicine production base， and lays a foundation for the scientific and standardized production of high-quality Dai medicine.
ABSTRACT
Ethnic medicine is an important part of traditional Chinese medicine, which has encountered many problems in the development process, such as the lack of effective inheritance of valuable experience and practice, weak basic research and lack of talents, serious destruction of ethnic medicine resources, uneven quality of medicinal materials, weak intellectual property protection, etc. To sum up, these seriously restrict the development of ethnic medicine. Here, the authors propose some corresponding suggestions according to these problems. Firstly, we should try our best to protect and mine relevant professional books for promoting national medicine culture, establish complete system of national and local standards, strengthen the construction of standardized planting bases and germplasm resource banks, build a well-known brand of ethnic medicine and give full play to the leading role of the brand. Secondly, we should strengthen basic research on ethnic medicine and build an integrated system of production-study-research. By integrating the strength of culture, scientific research, talents and industry, this paper hopes to promote the vigorous development of ethnic medicine.
ABSTRACT
The adulteration of herbal products is a threat to consumer safety. In the present study, we surveyed the species composition of commercial Radix Clerodendri Japonicum products using DNA barcoding as a supervisory method. A reference database for plant-material DNA-barcode was successfully constructed with 48 voucher samples from 12 Clerodendrum species. The database was used to identify 27 Radix Clerodendri Japonicum decoction piece samples purchased from drug stores and hospitals. The DNA sequencing results revealed that only 1 decoction piece (3.70%) was authentic C. japonicum, as recorded in the Dai Pharmacopeia, whereas the other samples were all adulterants, indicating a potential safety issue. The results indicate that decoction pieces that are available in the market have complex origins and that DNA barcoding is a suitable tool for regulation of Dai medicines.

ABSTRACT
Objective: For the purpose of finding new bioactive agents from ethnic medicines, the chemical study on Dai Medicine Cassia alata was carried out. Methods: The chemical constituents from the twigs of C. alata were isolated by column chromatographic methods of silica gel, MCI-Gel resin, Sephadex LH-20, and HPLC. The structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. The cytotoxicity of this compound for NB-4, A-549, SHSY5Y, PC-3, and MCF-7 cells line was also evaluated by using the MTT method. Results: Four 2-arylbenzofuran compounds were isolated from this plant and identified as 7- methoxy-2-(4-methoxyphenyl)-3,5-dimethylbenzofuran (1), moracin N (2), 2-(2'-methoxy-4'-hydroxy-aryl)-3-methy-6-hydroxybenzofuran (3), and moracin P (4). Conclusion: Compound 1 is a new compound named as 7-methoxy-2-(4-methoxyphenyl)-3,5-dimethylbenzofuran. Compound 1 also displays the high cytotoxicity to tested cancer cell-line.
ABSTRACT
Xishuangbanna Dai prefecture has high temperature and high humidity all throughout the year, and puerperal diseases are very common to local Dai women. This paper focused on the medicinal plants using knowledge by Xishuangbanna Dai ethnic people and conducted a series of medicinal ethnobotanical study. In total, 27 plant species were investigated and recognized; The plants near to Dai village had the highest utilization; The selection of medicinal plant reflects the manifested time and space characteristics; Taking herbal decoction with water was the most-used method; Furthermore, the local Dai people attached more importance to the compatibility of different medicines to get better curative effect. The study indicates that the Dai medicine should take the different time and occasion into account when used for treating puerperal diseases, and the treatment is very complicated and variable. The authors have called on more attention to Dai medicinal ethnobotanical study.
ABSTRACT
By reviewing documents and learning from the Dai medicine teachers, the papertried to show the theory and methods of Dai medicine on diagnosing and treating Rheumatoid arthritis (RA). Dai medicine took a note that RA was caused by the unbalance of the interal Sita and affected by the external Paya Longgananhuang. Those pathogeny can make the partial joint and muscle's function abnormal, which resulted in the RA. RA can be separated into three types which are Longmengshahoufeixiang. They could be treated by boththe internal and external treatments. The etiology and pathogenesis of RA and its diagnosis and treatment methods of traditional Dai medicine were profound, unique and useful. It`s worth of clinical application and further researches.

ABSTRACT
In order to find out the composition, characteristics and traditional utilization characteristics of Dai medicine and promote the rational protection, inheritance and utilization of the resources and traditional knowledge of Dai medicine in China, the resources of traditional Dai medicine have been investigated systematically and the traditional knowledge of Dai medicine have been analyzed in the article. We found out that there were altogether 1 077 kinds of traditional Dai medicine in China and among which 272 were the first time recorded in the condition of Dai folk medical uses. There were 1 053 plant medicines which belong to 169 family and 694 genus. These plant medicines mainly distributed in the southern, west southern and east southern area of Yunnan province, the southern area of Guangxi, Guangdong, Guizhou, Sichuan, Fujian province and tropical, subtropical district as Taiwan, and more than 94.49% plant medicines could be found in Yunnan province. From the point of plant life form, they were major herbaceous or shrubby plants; When it is used as medicinal part, root and rhizome of plants account for the highest proportion, the next were whole plant and leaves. From nature, flavor and channel tropism points of view, the largest proportion of Dai medicines were cool, bitter-tasted and possesses water element. In terms of treatment of disease types, most of the drugs can treat gastrointestinal diseases, next were drugs that could be used to treat upper respiratory infection, traumatological and rheumatic diseases, urinary infection, gynecological diseases, hepatopathy, puerperium fever and diseases caused by poisonous insects and beast of prey bite. The study revealed that the resources of traditional Dai medicine and traditional knowledge of application were abundant in China, but the resources of traditional Dai medicine and traditional knowledge of application were faced with the risk of gradually reduce and loss. The article suggested that we should take measures to strengthen the study of protection and utilization of important traditional Dai medicine and endangered resources along with the protection and transmission of traditional knowledge of Dai nationalistic medicine.
