Haplotype diversity and the mean pairwise differences were 0.9903±0.0013 and 5.7785 in HVS-I, and 0.9777±0.0013 and 3.5819 in HVS-II, respectively. By analyzing the hypervariable domain from nucleotide 1,6180 to 1,6193 in HVS-I, we defined some new types of sequence variations. We also compared the relationship between Tu population and other populations using mtDNA HVS-I sequences. According to Rst genetic distances, the phylogenetic tree showed that the Tu population, the Xi＇an Han population, the Chinese Korean, and the Mongol ethnic group were in a clade. This indicated a close genetic relationship between them. There were far relations between the Tu population and other Chinese southern Han populations, Siberian, European, African, and other foreign populations. The results suggest that Tu population has a multi-origin and has also merged with other local populations.展开更多

It argues that the taxonomic effort of grouping different non-Hart ethnicities together into a single category of minority cinema is a sociopolitical attempt to construct, maintain and control the definition of ethnic minorities. It calls into question not what is within the film, but the classificatory practices outside of the film collectively engaged by the government, the film industry, the critics and the mass audience. Moving away from the methods of examining the representation and generic conventions of the cinema other scholarship has employed, this article emphasizes the classification system used during the time of the cinema. By comparing it with a similar classificatory problem in Western national history, using an epistemological perspective, this article criticizes the negative impact inevitably left in rhetorically driven classification systems.展开更多

For instance, ethnomedicines of Chinese ethnic minorities constitute an important part of traditional medicines. In our study, we firstly clarified the concept of ethnomedicines and the connotations of ethnopharmacology. The particularity of ethnomedicine research were then summed up, and the development profiles of the ethnomedicines of Chinese ethnic minorities were discussed by investigating the current status and existing problems. On this basis, we abstracted the innovative development path of ethnomedicines for the first time, which was found to follows：resource study -, standardized development research -~ industrialization of the achievements and efforts for internationalization. We found that platform establishment and team training are keys to achieving innovative development. Hence, this study provided a basis for ethnomedicine development.展开更多
