THE STUDY OF POPULATION GENETIC RELATION AMONG TEN ETHNIC GROUPS IN NORTHWEST CH INA

Objective To investigate the genetic relation am on g ten ethnic groups in northwest China. Methods Allele frequ encies of six STR(short tandem repeat ) loci in D13S1358, VWA, FGA, D5S818, D13S 317, and D7S820 were collected from Lasa Tibetan, Changdu Tibetan, Xi'an Han, G ansu Dongxiang, Gansu Yugu, Xinjiang Uygur, Ozbak, Kirgiz, Sibe, Ningxia Hui by the results of State Key laboratory, Forensic Science Department, school of medi cal, Xi'an Jiaotong University and internet biological information data bank, a nd compared with that of the Mongolian, Zhuang in China, and White and Negro in USA. The polymorphism index (H, DP, PPE, PIC) and genetic distance, then the phy logenetic tree of all population were reported. Results The res ulting tree topology exhibited strong geographic and racial partitioning consist ent with that obtained with HLA and classical genetic polymorphisms. Conclusion The results suggest that forensic STR loci may be particular ly powerful tools and provide the necessary fine resolution for the reconstructi on of recent human evolutionary history.

Indigenous Knowledge on Soil Classification of Ethnic Groups in Luang Prabang Province of the Lao PDR

The objectives of this study were to demonstrate ethno-scientific elicitation techniques in retrieving indigenous knowledge at village-level, and to document the indigenous soil classification systems of different ethnic groups in Luang Prabang province in the Lao PDR. The study area comprised three villages – Nambo, Huaymaha and Thapo, in the Phonxay district of Luang Prabang province. Three ethnic groups were covered by the study – Hmong, Khmu and Lao Loum. All three ethnic groups used soil color as main criteria for soil classification. However, even within the same ethnic group, sometimes different villages have differences in the way they classify soils; this was apparent for the Hmong ethnic group in the villages of Huaymaha and Nambo. A significant difference of the Lao Loum ethnic group from the other two, was the emphasis used in classifying soil types according to their water holding capabilities. In contrast, the Khmu and Hmong classified many soil types in relation to their rock content (‘with rock’ or ‘pure rock’ sometimesbeing used). The results of the study suggest that the ethnic groups classify the soils in relation to their potential for different types of agricultural production.

Common Development of All Ethnic Groups

China’s ethnic minorities not only enjoy the equal rights with the majority Hans as endowed by the Constitution and other laws, but also enjoy the right to regional autonomy in areas where minorities live in compact communities. In February 2001, the NPC Standing Committee revised the law on ethnic regional autonomy for minorities, adding new provisions on increasing investment in the areas of ethnic minorities to accelerate local development.

Comparative study of type 2 diabetes mellitus-associated gut microbiota between the Dai and Han populations

BACKGROUND The global prevalence of type 2 diabetes mellitus(T2DM)is increasing.T2DM is associated with alterations of the gut microbiota,which can be affected by age,illness,and genetics.Previous studies revealed that there are discriminating microbiota compositions between the Dai and the Han populations.However,the specific gut microbiota differences between the two populations have not been elucidated.AIM To compare the gut microbiota differences in subjects with and without T2DM in the Dai and Han populations.METHODS A total of 35 subjects of the Han population(including 15 healthy children,8 adult healthy controls,and 12 adult T2DM patients)and 32 subjects of the Dai population(including 10 healthy children,10 adult healthy controls,and 12 adult T2DM patients)were enrolled in this study.Fasting venous blood samples were collected from all the subjects for biochemical analysis.Fecal samples were collected from all the subjects for DNA extraction and 16S rRNA sequencing,which was followed by analyses of the gut microbiota composition.RESULTS No significant difference in alpha diversity was observed between healthy children and adults.The diversity of gut microbiota was decreased in T2DM patients compared to the healthy adults in both the Dai and Han populations. There was a significant difference in gut microbiota between healthy children and healthy adults in the Hanpopulation with an increased abundance of Bacteroidetes and decreased Firmicutes in children. However, thisdifference was less in the Dai population. Significant increases in Bacteroidetes in the Han population and Proteobacteriain the Dai population and decreases in Firmicutes in both the Han and Dai population were observed inT2DM patients compared to healthy adults. Linear discriminant analysis Effect Size analysis also showed that thegut microbiota was different between the Han and Dai populations in heathy children, adults, and T2DM patients.Four bacteria were consistently increased and two consistently decreased in the Han population compared to theDai population.CONCLUSION Differences in gut microbiota were found between the Han and Dai populations. A significant increase inBacteroidetes was related to the occurrence of T2DM in the Han population, while a significant increase in Proteobacteriawas related to the occurrence of T2DM in the Dai population.

Mongolian AN ethnic group known for ＂growing up on horsebacks,＂ the Mongolians live mostly in the In- ner Mongolia Autonomous Region in the northern part of China, which includes vast tracts of excel- lent natural pastureland with numerous herds of cattle, sheep, horses and camels. The rest are also distributed in Liaoning Jilin. Heilongjiang. Qinghai and Gansu provinces. Living on grasslands and relying on raising stock as their economic mainstay, the Mongolians have kept their nomadic living style for hundreds of years. Mongolian herdsmen used to live in yurts,which were usually seven to eight feet high and 10 feet in diameter, with an opening in the top of the umbrella-shaped roof. The structure can offer ideal ventilation and good protection against wind and cold. After the mid-20th century, as more and more herdsmen ended their nomadic life and settled down, they began to build yurt-like houses made of mud and wood.

Upholding Equality and Unity Among Ethnic Groups, and Freedom of Religious Belief

Since the founding of the People＇s Republic of China, the Chinese government, to ensure equality and unity among ethnic groups and achieve their common development, has formulated a series of ethnic and religious policies on the basis of the actual situations of the various ethnic groups and religions, and these policies have been continuously enriched and improved in practice.

It is still in use but a new Latinized form was developed in 1954.

DongTHE Dong people live mainly in Guizhou and Hunan provinces though they can also be found in the Guangxi Zhuang Autonomous Region, as well as Jiangsu, Guangdong and Zhejiang provinces. In addition to agriculture, they make their living by growing timber trees, which are then logged and sold. Trees are so important in their lives that they have a unique custom of planting 18 fir trees when a child is born. When the child reaches the age of 18 and gets married, the matured fir trees are felled and used to build houses for the bride and groom
