A Study on the Chess Culture of Ethnic Minority Groups in Gansu Province

As a region inhabited by large populations of ethnic minority groups, Gansu province boasts rich ethnic cultural resources which reflect traditional culture and intangible cultural heritage that had taken shape thousands of years ago. Among these are various ethnic folk chess games. They are time-honored with many types such as the “Fang” chess of the Hui ethnic group, the “Jiu” chess of the Tibetans, the “King and Ministers” chess, the Mongolian chess, the Mongolian military chess, etc. These games embody distinctive ethnic and regional characteristics, as well as the cultural elements of a particular ethnic minority group. It is of great significance, therefore, to study the ethnic chess by collecting, documenting and comparing different types of related chess. The paper explores ways to standardize, protect and promote them scientifically in joint efforts, and draws a conclusion that examining their significance in the present era and the ethnic characteristics is the key to understanding the profound culture behind the chess.

民族,还是“族群”——释ethnic group一词的涵义

“氏族→部落→民族”是人们共同体演进的普遍规律。在世界人们共同体演进的过程中没有“族群”位置 ,不宜以“族群”取代民族 ,也不宜以“族群”表达民族以下支系。

本文从族群与民族概念的争论入手,揭示族群概念的引入是关于中国民族研究的深入。指出以族群替代民族是不能有效解决中国的民族问题的。由于中文"民族"一词已为民众所熟悉并在实际中不致引起误解,族群与民族可以在不同的层次上运用。

An epidemiology study of bronchial asthma in the Li ethnic group in China

Objective:To investigate the prevalence and risk factors of bronchial asthma in the Li ethnic group in Hainan,China.Methods:This study employed a stratified random sample design using custom-designed questionnaires.Subjects with asthma-like symptoms were first identified by two rounds of surveys and then confirmed by respiratory physicians using pulmonary function test,bronchial dilation test and challenge test.Demographic data,information on family history of asthma,history of allergies,smoking habits,domestic cooking fuel and other potential risk factors were collected.Logistic regression was performed to evaluate risk factors for asthma.Results: The prevalence of asthma in the Li ethnic group was 3.38%,much higher than the national average level in China.Aging,agriculture industry(the rubber industry in particular),rural residence,family history of asthma,history of allergies,cold air,inhalation of dust and irritant gases,smoking,domestic cooking fuel and living environment were associated with increased risk of asthma.Conclusions:The high prevalence of asthma in the Li ethnic group highlights the importance of asthma prevention and treatment in this population.Risk factors indentified in this study warrant special attention.Elevating public awareness about asthma in local communities will benefit the prevention of the disease.

Correlation between the Xba Ⅰ polymorphism of apoB gene and serum lipid profiles in Li ethnic group

Objective:To study correlation between the Xba I polymorphism of apoB gene and plasma lipid profiles in Li ethnic group.Methods:Total 1S1 cases of healthy Li people were recruited randomly by cluster sampling and 200 Han people were recruited as control;blood was drawn to analyze Xba I polymorphism distribution of apoB gene and serum lipid levels.Results:There were lower serum total cholesterol(TC)and low density lipoprotein cholesterol(LDL-C)levels in serum of Li people;while,high density lipoprotein cholesterol(HDL-C),X^-/X^-genotype and X^+allele frequencies exhibited higher levels than Han people.Interestingly,HDL-C level was reduced,while LDL-C level was enhanced in subjects carrying heterozygous(X^-/X^-)genotype compared to homozygous(X^-/X^-)genotype.Additionally,there were no difference in serum level of triglyceride,TC,apoprotein A(apo A)and apoprotein B(apo B)between Li and Han people,the same results were showed between X^-/X^+and X^-/X^-genotype carriers.Conclusions:XbaⅠpolymorphism of apoB gene is correlated to the profiles of serum lipid level,X^-/X^+genotype carriers are phenotyped with higher LDL-C level and lower level of HDL-C in Li ethnic group.

Genetic polymorphism of mitochondrial DNA HVS-I and HVS-II of Chinese Tu ethnic minority group

We analyzed the two hypervariable segments HVS-I and HVS-II of 108 Chinese Tu ethnic minority group samples for forensic and population genetics purposes, Comparing with Anderson sequence, 79 polymorphic loci in HVS-I and 40 in HVS-II were found in Chinese Tu ethnic minority group mtDNA sequences, and 90 and 64 haplotypes were then defined. 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.

Form Gene Clustering Method about Pan-Ethnic-Group Products Based on Emotional Semantic

The use of pan-ethnic-group products form knowledge primarily depends on a designer＇s subjective experience without user participation. The majority of studies primarily focus on the detection of the perceptual demands of consumers from the target product category. A pan-ethnic-group products form gene clustering method based on emotional semantic is constructed. Consumers＇ perceptual images of the pan-ethnic-group products are obtained by means of product form gene extraction and coding and computer aided product form clustering technology. A case of form gene clustering about the typical pan-ethnic-group products is investigated which indicates that the method is feasible. This paper opens up a new direction for the future development of product form design which improves the agility of product design process in the era of Industry 4.0.

Analysis of the Features of the Vernacular Plank Houses of the Qiang Ethnic Group in Southern Songpan County: A Case Study of Xiaoxinggou

The Qiang ethnic group in southern Songpan county lives in vernacular plank houses(VPHs) with an architectural tradition that dates to the period of the ancient Di people.VPHs are now mainly constructed in settlements of ethnic groups such as Baima Tibetans, Amdo Tibetans, and the Qiang people living in Wenxian county, Longnan city of Gansu province, and Maoxian, Lixian, Wenchuan, and Beichuan of Sichuan province respectively.Although VPHs of the Qiang people living in southern Songpan share many similarities with those of adjacent Tibetans in structure, construction, and spatial layout, they feature the Qiang people's unique architectural culture, and reflect a style transition from VPHs in the north to blockhouses in the south.The VPHs, as represented by those in Xiaoxinggou, play a significant role in the diversified architectural culture of this ethnic group.Their unique cultural value is worthy of further exploration and protection.

Endogamous marriage and the prevalence of hemoglobin E in ethnic groups of northern Thailand

Objective:To investigate the impact of the endogamous marriage culture on the prevalence of the hemoglobin E(HbE) recessive variant.Methods:The prevalence of the hemoglobin E(HbE)recessive variant was determined by dot-blot hybridization in 4 endogamous villages(1 Mlabri and 3 Htin ethnic groups) in comparison with 9 other nearby non-endogamous populations.Results:Although the overall HbE prevalence in the population studied(8.44%,33/391)was not significantly different from that of the general southeast Asian population,a high prevalence and individuals with homozygous HbE were observed in two villages,the Mlabri from Wiang Sa district and the Htin from Thung Chang district of Nan province(26.3%and26.9%,respectively).The low HbE allelic frequency noticed in some endogamous populations suggests that not only endogamy but also other evolutionary forces,such as founder effect and HbE/β-thalassemia negative selection may have an effect on the distribution of the HbE trait.Conclusion:Our study strongly documents that cultural impact has to be considered in the extensive prevalence studies for genetic disorders in the ethnic groups of northern Thailand.

ANALYZING HLA HAPLOTYPE OF THE LOCI HLA-A,-B, AND-DRB1 IN MONGOLIA ETHNIC GROUP

Objective To investigate HLA-A,-B and -DRB1 allele and HLA-A-B-DRB1 haplotype frequencies in Mongolia ethnic group. Methods HLA-A, -B, -DRB1 allele and haplotype in the Mongolia ethnic group were investigated based on 93 individuals by PCR- sequence-based typing (SBT) method. Results Twenty-one alleles were detected for HLA-A, 44 for HLA-B, and 26 for HLA-DRB1. The most frequent alleles were HLA-A*2402(0.2097), HLA-B*1302(0.0699), and HLA-DRB1*0701(0.1237). The most common HLA-A-B-DRB1 haplotype were A*3001-B*1302-DRB1*0701, A*0101-B*3701-DRB1*1001, followed by the A*0201-B*4601-DRB1*0901, A*2402-B*4801-DRB1*1101, A*2402-B*5201-DRB1*1501, A*3201-B*3503-DRB1*1301, and A*3303-B*5801-DRB1*0301, which were also presented in Chinese populations. Conclusion The data can be used in forensic and paternity tests to estimate the frequency of a DNA profile or anthropologic research. The characteristics of the distribution of HLA alleles revealed that Mongolia ethnic group is characterized by northern Mongolian Chinese.

Out of a total of 101 individuals, 96 showed different haplotypes; 91 were unique; 5 were found 2 times. The haplotype diversity for 6 Y-STR loci was 0.9990. Conclusion The date obtained can be valuable for individual identification, paternity testing in forensic fields and for population genetics because of 6 Y-STR loci high polymorphism.

3D Morphological Study of the Indian Arthritic Knee: Comparison with Other Ethnic Groups and Conformity of Current TKA Implant

Background: Studies have shown that there are striking variations in knee morphology between Asian and Western population. However, most of the existing total knee arthroplasty (TKA) implants are designed to suit the anatomy of Western population. Our study investigated anthropometry of Indian arthritic knees and compared them to international ethnic groups. Methods: Computed tomography was used to create 3D knee models and obtain anthropometric data of distal femur and proximal tibia of Indian arthritic knees. Femoral measurements included mediolateral length, medial and lateral anteroposterior length, medial and lateral condylar width and aspect ratio. Tibial measurements included mediolateral length, medial, lateral and central anteroposterior length and aspect ratio. A preoperative virtual implantation using Western TKAimplants was carried out to visualize anatomical conformity. Results: Statistical analysis results showed that Indian males had significantly larger femoral and tibial mediolateral and anteroposterior width than Indian females;however, femoral and tibial aspect ratio was similar for both. In case of females, significant difference was observed between medial and lateral condylar widths. When compared to knee anthropometry of other ethnic groups, femoral and tibial aspect ratio of Indian knees was found to be similar to the Asian population and different from the Western population. The virtual implantation showed overhang of the femoral component in both lateral and medial regions. Conclusion: Morphological mismatch between Western and Indian knees established the fact that Western implants have drawbacks when implanted in Indian patients. The study also provided a basis for designing gender-specific TKA implants for the Indian population.

Breast Density: Does It Vary among the Main Ethnic Groups in Malaysia?

Breast cancer is one of the common cancers among Malaysians and there are associated risk factors which include breast density. Therefore, this study was done to determine the association of breast cancer risks among ethnic groups in relation to breast density. Mammography was done on 300 women with equal numbers of Malays, Chinese and Indians with a mean age of 53.35 ± 7.4 years. Mammograms were evaluated using BI-RADS (Breast Imaging Reporting and Data System) protocol by two independent radiologists for breast density categorization. Chi-square analysis showed an association between breast density and age factor (p 0.05) whereas body mass index (BMI) was inversely associated with breast density (p > 0.05). There was significant difference in number of children and menopausal status (p 0.05). Results showed that 65% of Chinese subjects had denser breast density composition as to 50% in Malays and 35% in Indians. There was significant difference between breast density of three ethnic groups (p 0.05) with Chinese having 2.4 times denser breast (OR = 2.45, 95% CI: 1.466 - 3.948) followed by Malays (OR = 1.020, 95% CI: 0.681 - 1.689) and lowest in Indians (OR = 0.406, 95% CI: 0.247 - 0.668). Based on breast density, the Chinese are at a higher risk of developing breast cancer followed by Malays and lastly Indians.
