METHO...AIM:To investigate the contribution of fucosyltransferase 2 (FUT2) variants to the genetic susceptibility and clinical heterogeneity of ulcerative colitis (UC) between Han and Uyghur patients in Xinjiang, China. METHODS:A total of 102 UC patients (53 Han patients including 22 men and 31 women, and 49 Uyghur patients including 25 men and 24 women; aged 48 ± 16 years) and 310 age-and sex-matched healthy controls were enrolled from January 2010 to May 2011 in Xinjiang People's Hospital of China. UC was diagnosed based on the clinical, endoscopic and histological findings following Lennard-Jones criteria. Blood samples were collected and genomic DNA was extracted by the routine laboratory methods. Polymerase chain reaction-sequence-based typing method was used to identify FUT2 variants rs281377, rs1047781, rs601338 and rs602662. Genotypic and allelic frequencies were documented and compared between the UC patients and the healthy controls. Genotypic frequencies were also compared between Han and Uyghur patients. Potential association of genetic variation and UC between Han and Uyghur patients was examined. RESULTS: rs281377 was found significantly associated with UC in the Han population as compared with the controls (P = 0.011) while rs281377 was not associated with UC in the Uyghur population (P = 0.06). TT homozygous rs281377 frequencies were higher in the UC groups than in the controls (88.7% vs 68.7% and 55.1% vs 50.3%). rs1047781 was specifically associated with UC in the Uyghur population (P = 0.001), but not associated with UC in the Han population (P = 0.13). TT homozygous rs1047781 frequencies were lower in the UC groups than in the controls (9.5% vs 11.8% and 4.0% vs 6.7%). rs601338 was statistically related to UC in both populations (Han, P = 0.025; Uyghur, P = 8.33 × 10 -5 ). AA homozygous rs601338 frequencies were lower in the UC groups than in the controls (0% vs 1.8% and 12.2% vs 13.4%). No association was found between rs602662 and UC in both Han and the Uyghur populations. Allelic analysis showed that rs281377 allele was significantly associated with UC in the Han population as compared with the controls [P = 0.001, odd ratio (OR) = 0.26], however, it was not associated with UC in the Uyghur population (P = 0.603, OR = 1.14), and rs1047781 allele was associated with UC in the Uyghur population (P = 0.001, OR = 0.029) while it was not associated with UC in the Han population (P = 0.074, OR = 0.62). Moreover, rs601338 was associated with UC in both Han (P = 0.005, OR = 0.1) and Uyghur pop- ulations (P = 0.002, OR = 0.43). Meta analysis showed that rs1047781 and rs601338 conferred risk of UC as compared with the controls [P = 0.005, OR = 0.47; P = 0.0003, OR = 0.35; 95% confidence interval (CI) = 0.31-0.72 and 0.21-0.58], but rs281377 and rs602662 showed no statistically significant differences betweenpatients with UC and controls (P = 0.10, OR = 0.71; P = 0.68, OR = 0.09; 95% CI = 0.47-1.07 and 0.56-1.47). CONCLUSION:Functionally relevant FUT2 gene variants are associated with UC, suggesting that they play a potential role in the pathogenesis of UC and may contribute to the clinical heterogeneity of UC between Han and Uyghur patients.展开更多

Methods： Between 01/01/2000 and 31/12/2012, 319 Uyghur HCC patients were treated at the Cancer Centre of The First Affiliated Hospital of Xinjiang Medical University. The data for the patients were obtained from a retrospective review of the patients＇ medical records. A total of 18 patients were excluded from the study because of incomplete information. The patients were classified into two groups： viral HCC and NBC-HCC. The clinical characteristics and prognostic factors were statistically analysed.Results： For all 301 patients, gender（P=0.000）, area of residence（P=0.002）, diabetes mellitus（P=0.009）, BMI（P=0.000）, cirrhosis（P=0.000）, tumour stage（P=0.004）, Child-Pugh class（P=0.000）, the TBIL level（P=0.000）, and the alpha-fetoprotein（AFP） level（P=0.000） were significantly different between the NBC-HCC and viral HCC groups. The NBC-HCC patients tended to be diagnosed at advanced stages; however, the NBC-HCC patients exhibited lower Child-Pugh scores than the viral HCC patients. In all patients examined, the 0.5-, 1-, 3- and 5-year overall survival（OS） rates were 35.6%, 20.3%, 12.6% and 4.5%, respectively. No significant difference in OS was observed between the two groups（P=0.124）. Cox multivariate analysis revealed that age（RR =1.539, P=0.001）, TNM stage（RR =12.708, P=0.000）, portal vein tumour thrombus（PVTT）（RR =2.003, P=0.000）, Child-Pugh class（RR =1.715, P=0.000）, and TACE ＋ radiotherapy/RFA（RR =0.567, P=0.000） were significant independent prognostic factors for HCC patients. Conclusions： The clinical characteristics differ between Uyghur patients with NBC-HCC and viral HCC. HCC in the Xinjiang region displays specific regional characteristics. Age, TNM stage, PVTT, Child-Pugh class and TACE ＋ radiotherapy/RFA are significant risk factors that influence patient survival.展开更多

METHODS:In this study, 102 UC patients (53 Han including 22 men and 31 women, and 49 Uyghur patients including 25 men and 24 women; aged 48.07 ± 15.83 years) and 310 age- and sex-matched healthy controls were enrolled in the Department of Gastroenterology, Xinjiang People's Hospital of China from January 2010 to May 2011. UC was diagnosed based on the clinical, endoscopic and histological findings following Lennard-Jones criteria. Blood samples were collected and genomic DNA was extracted by routine laboratory methods, and both polymerase chain reaction and gene sequencing were used to identify HLA-DRB1 allele variants. The potential association between genetic varia-tion and UC in Han and Uyghur patients was examined. There were no statistical differences in HLA-DRB1 allele frequencies in Han UC patients. RESULTS:There was no significant difference in the sex ratio between the controls and UC patients (P = 0.740). In Han patients with UC (n = 53), HLA-DRB1 *03 , *13 allele frequencies were lower than in healthy controls (n = 161), but not statistically significant, and HLA-DRB1*04*11*14 allele frequencies were higher than in healthy controls, but without statistical significance. Differences between Uyghur UC patients and the control group were observed for HLA-DRB1*04 and HLA-DRB1*13 , both showed a greater frequency in UC patients (10.21% vs 2.69%, P = 0.043; 14.29% vs 4.03%, P = 0.019). HLA-DRB1*14 also showed a greater frequency in UC patients (14.29% vs 2.69%, P = 0.006). The frequencies of DRB1*04 , *13*14 alleles were increased in Uyghur UC patients compared with normal controls. The frequency of DRB1 * 08 was decreased in Uyghur UC patients compared with normal controls. HLA-DRB1 alleles showed no association with UC in Han patients. There were no statistical differences in HLA-DRB1 allele frequencies in Han UC patients. The frequencies of DRB1*04 , *13*14 alleles were increased in Uyghur UC patients compared with normal controls. The frequency of DRB1*08 was decreased in Uyghur UC patients compared with normal controls. Polymorphism of the HLA-DRB1 gene may contribute to the clinical heterogeneity of UC between Han and Uyghur UC patients in China. CONCLUSION:HLA-DRB1*04*13*14 and DRB1*08 may contribute to the clinical heterogeneity of UC between Han and Uyghur UC patients.展开更多

In previous genetic studies about dyslexia, a number of candidate genes have been identified. These include DCDC2, which has repeatedly been associated with developmental dyslexia in various European and American populations. However, data regarding this relationship are varied according to population. The Uyghur people of China represent a Eurasian population with an interesting genetic profile. Thus, this group may provide useful information about the association between DCDC2 gene polymorphisms and dyslexia. In the current study, we examined genetic data from 392 Uyghur children aged 8–12 years old from the Xinjiang Uyghur Autonomous Region of China. Participants included 196 children with dyslexia and 196 grade-, age-, and gender-matched controls. DNA was isolated from oral mucosal cell samples and fourteen single nucleotide polymorphisms（rs6456593, rs1419228, rs34647318, rs9467075, rs793862, rs9295619, rs807701, rs807724, rs2274305, rs7765678, rs4599626, rs6922023, rs3765502, and rs1087266） in DCDC2 were screened via the SNPscan method. We compared SNP frequencies in five models（Codominant, Dominant, Recessive, Heterozygote advantage, and Allele） between the two groups by means of the chi-squared test. A single-locus analysis indicated that, with regard to the allele frequency of these polymorphisms, three SNPs（rs807724, rs2274305, and rs4599626） were associated with dyslexia. rs9467075 and rs2274305 displayed significant associations with developmental dyslexia under the dominant model. rs6456593 and rs6922023 were significantly associated with developmental dyslexia under the dominant model and in the heterozygous genotype. Additionally, we discovered that the T-G-C-T of the four-marker haplotype（rs9295619-rs807701-rs807724-rs2274305） and the T-A of the two-marker haplotype（rs3765502-1087266） were significantly different between cases and controls. Thus, we conclude that DCDC2 gene polymorphisms are associated with developmental dyslexia in Chinese Uyghur children.展开更多

For bilingual students, early vocabulary development often predicts their future bilingual success. This paper examines early bilingual receptive vocabulary knowledge of ethnic minority children(N=135) from two large ethnic language communities(Uyghur and Kazak) in three national-level povertystricken counties in Xinjiang, China. The children’s bilingual vocabulary knowledge was assessed using translated versions of the Peabody Picture Vocabulary Test-IV(PPTV-IV) in Putonghua(PTH) and their mother tongue(MT) Uyghur or Kazak. Data were analyzed through four General Linear Models(GLM). The analyses showed that both groups scored higher in MT vocabulary knowledge than that in their PTH, although the Kazak students’ MT vocabulary scores were lower than those of the Uyghurs. While gender, age, L1, or residence location were not significant factors in differences across the two groups in PTH, among the Kazak children, the main effect of age was significant in MT;and among Uyghur children, residence location had a significant effect. The two groups also differed in patterns of acquisition in different parts of speech(nouns, verbs, and attributes) with Uyghur children performing strongest in MT and PTH verbs. The findings have important implications for ensuring the quality of early bilingual education among impoverished Chinese minority communities.展开更多

These changes in the ...Profound cultural changes are transforming the Moslem world of Central Asia, partly as a response to dramatic events in the Middle East and partly to the great economic development in the region. These changes in the Moslem world especially affect the lives of women, since the cultural norms involving the protection of women are an important facet of Moslem life. The goal of this investigation is to show the importance of the ethnographic contribution to anthropological and sociological theory in investigating the new aspects of life in Central Asia. The first concept is the cultural identity of the Uyghur population of China. The second concept is that of Uyghur women, namely, the varied range of women from their role in a conservative, and patriarchal family structure to that of independent actors in a contemporary urban society. We understand that young Uyghur women face a more different set of choices than those of women in other Moslem cultures or in the rest of China. If they identify with their culture as Uyghur and Moslem, their culture restricts their opportunities as Chinese citizens. As students at Minorities University of China （MUC） in 13eijing, the relative freedom of Beijing influences them a great deal. Education and employment are the vehicles for integration into the larger Chinese group. Institutions, such as schools of ethnic studies, and the college competitive exam （the gaokao）, provide opportunities as well as obstacles for Uyghur women as part of the dynamic change in the Moslem world.展开更多

Though the poems are particularly used as religious texts at mosque preaching and other chances of Islamic proselytizing, their contents give insights into the ways of local Uyghurs to understand various daily happenings through the lens of Islamic doctrines. This issue can be taken as a process of the localization of Islamic culture among Uyghurs, therefore, it provides comprehensive pictures on the Islamic ways of local Uyghurs to accommodate their social realities. Through undertaking analyses on the structure, style, contents of the poems, this paper makes efforts to unfold the symbolic landscape of the poems implied, making clear the logic bases of those religious motifs and the attitudes Uyghur preachers had toward social realities.展开更多

A total of 341 Uyghur students between 12 and 15 years of age, attending 3 middle schools for both Han and ethnic minorities in Urumqi, responded to questionnaires requesting information about their language backgrounds, their use of language at school (inside and out of classroom) and in the wider community, their self-perceptions about their linguistic competence in Uyghur and in Chinese and their attitudes towards Uyghur, Chinese and towards bilingualism. The results, in general, demonstrated a positive attitude towards bilingualism, and there was a trend towards favoring the use of Chinese both inside and outside classroom. The implications of the findings for language policy and planning in education are discussed.展开更多

Metagenomic studies demonstrated the presence of significant differences in the structure of the intestinal microbiota in populations of Europeans and Asians. In this aspect,the Xinjiang Uygur Autonomous region of China is the most affected district,where substantially the indigenous Uighur,Kazakh and also Han populations is affected. There is an objective need to ascertain the microecological and metabolic status of persons of the indigenous population in Western China,which are in the risk zone. The test for microalbuminuria is reliable method of kidney failure primary stages diagnosis,reflecting the initial stages of vessel pathology and the development of MS. It invariably correlates with an increase of cardiovascular morbidity and mortality. We introduce this screening test for early detection of predisposition to the development of the MS in the example of Xinjiang population for use also in other regions of China.There is a need to carry out the search,selection and analysis of the new strains of probiotics in the Xinjiang from national milk products with lactic acid or other fermented products with the purpose of studying their clinical characteristics. This will have an impact on increasing life expectancy and improving the quality of life of the population of Xinjiang.展开更多
文摘BACKGROUND^(14)C urea breath test(^(14)C UBT)and immunohistochemical staining(IHC)are widely used for detection Helicobacter pylori(H.pylori)infection with different sensitivity,and there is a difference in H.pylori infection rate in Uyghur and Han ethnic groups.Both need large cohort studies to evaluate the differences more accurately.AIM To analyze the difference between^(14)C UBT and IHC for H.pylori detection in Xinjiang Uyghur Autonomous Region and the difference between Uyghur and Han populations.METHODS There were 3944 cases of H.pylori infection detected by both IHC and^(14)C UBT at the same time(interval<1 wk,with sampling site including gastric antrum,selected from 5747 patients).We compared the sensitivity of^(14)C UBT and IHC.We also compared 555 pairs of Han/Uyghur cases(completely matched for gender and age)for their H.pylori infection rates.The overall H.pylori infection rate of all 5747 cases and the correlation with other clinicopathological data were also further analyzed.SPSS V23.0 software was used for statistical analysis.RESULTS The sensitivity was 94.9%for^(14)C UBT and 65.1%for IHC,which was a significant difference(n=3944,P<0.001).However,among those cases negative for H.pylori by^(14)C UBT(detection value≤100),4.8%were positive by IHC.Combining both methods,the overall H.pylori infection rate was 48.6%(n=5747),and differences in gender,age group,ethnicity and region of residence significantly affected the H.pylori positive rates.According to age group(Han/Uyghur),the positive rates were≤30 years(62.2%/100.0%),31-40 years(45.2%/85.7%),41-50 years(47.2%/79.2%),51-60 years(44.6%/76.1%),61-70 years(40.9%/68.2%),71-80 years(41.7%/54.1%)and≥81 years(42.9%/NA).The H.pylori infection rates of Han/Uyghur paired cases were 41.4%and 73.3%,which was a significant difference(P<0.001)(555 pairs).H.pylori positivity was significantly related to moderate-severe grade 2-3 chronic/active gastritis and intestinal metaplasia(all P<0.05).CONCLUSION The sensitivity of^(14)C UBT was significantly higher,but combined application can still increase the accuracy.The prevention H.pylori should be emphasized for Uygur and young people.
文摘The Uyghur ethnic identity and their autochthony of Xinjiang continue to be a subject of academic discussions.However,Chinese authorities as well as Chinese scholars have a permanent position on these matters and reject any alternatives.The“Uyghur issue”has already become a part of the geopolitical game impacting world politics and academia as well.Kazakhstan is a good example of this influence.It has a long common border with northwestern China,a large Uyghur diaspora,and historical connections with Xinjiang.Nonetheless,academia nowadays puts Uyghur Studies in a peripheral position,first of all,because of the geopolitical factor.In this article,I focus on the Uyghurs’ethnic identity and autochthony of Xinjiang based on the historical background of this region covered by Kazakhs and other international historians.It helped me identify the origin of the“Uyghur issue”in the modern context,which explains why there is no global consensus on who the modern Uyghurs are and whether they have the right to claim independence of the territory of modern Xinjiang.During Xi Jinping’s era,control over Xinjiang has sharply strengthened and Kazakhstan has conspicuously showed solidarity with the People’s Republic of China(PRC).The Uyghurs’separatist aspirations are practically suppressed,but the voices of human rights supporters and Western academia have become louder,attracting the attention of the world community to the“Uyghur issue”.

文摘Uyghur medicine refers to the traditional medicine of the people residing in the oases of the Taklamakan desert in the North-West corner of modern China.Due to historical and geographical reasons,the ancestors of the modern Uyghurs had extensive contact with Greco-Roman civilization even beginning in the 4th century BCE,and continuing with different extent until the 6th century CE.Thus,the knowledge of Greek humoral medicine spread to the Uyghur regions.When Arab-Persian medicine arrived along with Islam in the 10th century,it met both Buddhist medicine and the developed folk medicine.In this paper,we argue that“Greco-Roman”,“Arab-Persian”and“Uyghur”medicines are all of essentially the same system under holistic humoral medicine.We further assert that“Traditional European Medicine”is based on the same tradition,and,while it was discarded in the West,it has been substantially preserved by the Uyghurs.We also consider the implications of making the two millennial tradition of Uyghur medicine the object of modern scientific research in China.
文摘Because of its peculiar language environment with multi ethnicities and the One Belt and One Road initiative,the studies of place names in Ili Kazak Autonomous Prefecture attract many linguists’interests.This paper focuses on characteristics studies of Uyghur place names in Ili Kazak Autonomous Prefecture based on Universal Principles of Tendencies proposed by the Polish linguist Witold Manczak.Through careful and thorough study,this paper found that because of different traditional lifestyles and different political strategies through different historical periods,as urban people,the Uyghur place names highlighted the Uyghur people’s great contributions to artificial constructions.

文摘AIM:To investigate the contribution of fucosyltransferase 2 (FUT2) variants to the genetic susceptibility and clinical heterogeneity of ulcerative colitis (UC) between Han and Uyghur patients in Xinjiang, China. METHODS:A total of 102 UC patients (53 Han patients including 22 men and 31 women, and 49 Uyghur patients including 25 men and 24 women; aged 48 ± 16 years) and 310 age-and sex-matched healthy controls were enrolled from January 2010 to May 2011 in Xinjiang People's Hospital of China. UC was diagnosed based on the clinical, endoscopic and histological findings following Lennard-Jones criteria. Blood samples were collected and genomic DNA was extracted by the routine laboratory methods. Polymerase chain reaction-sequence-based typing method was used to identify FUT2 variants rs281377, rs1047781, rs601338 and rs602662. Genotypic and allelic frequencies were documented and compared between the UC patients and the healthy controls. Genotypic frequencies were also compared between Han and Uyghur patients. Potential association of genetic variation and UC between Han and Uyghur patients was examined. RESULTS: rs281377 was found significantly associated with UC in the Han population as compared with the controls (P = 0.011) while rs281377 was not associated with UC in the Uyghur population (P = 0.06). TT homozygous rs281377 frequencies were higher in the UC groups than in the controls (88.7% vs 68.7% and 55.1% vs 50.3%). rs1047781 was specifically associated with UC in the Uyghur population (P = 0.001), but not associated with UC in the Han population (P = 0.13). TT homozygous rs1047781 frequencies were lower in the UC groups than in the controls (9.5% vs 11.8% and 4.0% vs 6.7%). rs601338 was statistically related to UC in both populations (Han, P = 0.025; Uyghur, P = 8.33 × 10 -5 ). AA homozygous rs601338 frequencies were lower in the UC groups than in the controls (0% vs 1.8% and 12.2% vs 13.4%). No association was found between rs602662 and UC in both Han and the Uyghur populations. Allelic analysis showed that rs281377 allele was significantly associated with UC in the Han population as compared with the controls [P = 0.001, odd ratio (OR) = 0.26], however, it was not associated with UC in the Uyghur population (P = 0.603, OR = 1.14), and rs1047781 allele was associated with UC in the Uyghur population (P = 0.001, OR = 0.029) while it was not associated with UC in the Han population (P = 0.074, OR = 0.62). Moreover, rs601338 was associated with UC in both Han (P = 0.005, OR = 0.1) and Uyghur pop- ulations (P = 0.002, OR = 0.43). Meta analysis showed that rs1047781 and rs601338 conferred risk of UC as compared with the controls [P = 0.005, OR = 0.47; P = 0.0003, OR = 0.35; 95% confidence interval (CI) = 0.31-0.72 and 0.21-0.58], but rs281377 and rs602662 showed no statistically significant differences betweenpatients with UC and controls (P = 0.10, OR = 0.71; P = 0.68, OR = 0.09; 95% CI = 0.47-1.07 and 0.56-1.47). CONCLUSION:Functionally relevant FUT2 gene variants are associated with UC, suggesting that they play a potential role in the pathogenesis of UC and may contribute to the clinical heterogeneity of UC between Han and Uyghur patients.

文摘Objective： To compare the clinical characteristics and prognosis between hepatitis virus-related hepatocellular carcinoma（viral HCC） and non-B, non-C HCC（NBC-HCC） among Uyghur patients in Xinjiang province, China. Methods： Between 01/01/2000 and 31/12/2012, 319 Uyghur HCC patients were treated at the Cancer Centre of The First Affiliated Hospital of Xinjiang Medical University. The data for the patients were obtained from a retrospective review of the patients＇ medical records. A total of 18 patients were excluded from the study because of incomplete information. The patients were classified into two groups： viral HCC and NBC-HCC. The clinical characteristics and prognostic factors were statistically analysed.Results： For all 301 patients, gender（P=0.000）, area of residence（P=0.002）, diabetes mellitus（P=0.009）, BMI（P=0.000）, cirrhosis（P=0.000）, tumour stage（P=0.004）, Child-Pugh class（P=0.000）, the TBIL level（P=0.000）, and the alpha-fetoprotein（AFP） level（P=0.000） were significantly different between the NBC-HCC and viral HCC groups. The NBC-HCC patients tended to be diagnosed at advanced stages; however, the NBC-HCC patients exhibited lower Child-Pugh scores than the viral HCC patients. In all patients examined, the 0.5-, 1-, 3- and 5-year overall survival（OS） rates were 35.6%, 20.3%, 12.6% and 4.5%, respectively. No significant difference in OS was observed between the two groups（P=0.124）. Cox multivariate analysis revealed that age（RR =1.539, P=0.001）, TNM stage（RR =12.708, P=0.000）, portal vein tumour thrombus（PVTT）（RR =2.003, P=0.000）, Child-Pugh class（RR =1.715, P=0.000）, and TACE ＋ radiotherapy/RFA（RR =0.567, P=0.000） were significant independent prognostic factors for HCC patients. Conclusions： The clinical characteristics differ between Uyghur patients with NBC-HCC and viral HCC. HCC in the Xinjiang region displays specific regional characteristics. Age, TNM stage, PVTT, Child-Pugh class and TACE ＋ radiotherapy/RFA are significant risk factors that influence patient survival.

文摘AIM:To evaluate the association between HLA-DRB1 alleles and Han and Uyghur ulcerative colitis (UC) patients residing in the Xinjiang Uyghur Autonomous Region of China. METHODS:In this study, 102 UC patients (53 Han including 22 men and 31 women, and 49 Uyghur patients including 25 men and 24 women; aged 48.07 ± 15.83 years) and 310 age- and sex-matched healthy controls were enrolled in the Department of Gastroenterology, Xinjiang People's Hospital of China from January 2010 to May 2011. UC was diagnosed based on the clinical, endoscopic and histological findings following Lennard-Jones criteria. Blood samples were collected and genomic DNA was extracted by routine laboratory methods, and both polymerase chain reaction and gene sequencing were used to identify HLA-DRB1 allele variants. The potential association between genetic varia-tion and UC in Han and Uyghur patients was examined. There were no statistical differences in HLA-DRB1 allele frequencies in Han UC patients. RESULTS:There was no significant difference in the sex ratio between the controls and UC patients (P = 0.740). In Han patients with UC (n = 53), HLA-DRB1 *03 , *13 allele frequencies were lower than in healthy controls (n = 161), but not statistically significant, and HLA-DRB1*04*11*14 allele frequencies were higher than in healthy controls, but without statistical significance. Differences between Uyghur UC patients and the control group were observed for HLA-DRB1*04 and HLA-DRB1*13 , both showed a greater frequency in UC patients (10.21% vs 2.69%, P = 0.043; 14.29% vs 4.03%, P = 0.019). HLA-DRB1*14 also showed a greater frequency in UC patients (14.29% vs 2.69%, P = 0.006). The frequencies of DRB1*04 , *13*14 alleles were increased in Uyghur UC patients compared with normal controls. The frequency of DRB1 * 08 was decreased in Uyghur UC patients compared with normal controls. HLA-DRB1 alleles showed no association with UC in Han patients. There were no statistical differences in HLA-DRB1 allele frequencies in Han UC patients. The frequencies of DRB1*04 , *13*14 alleles were increased in Uyghur UC patients compared with normal controls. The frequency of DRB1*08 was decreased in Uyghur UC patients compared with normal controls. Polymorphism of the HLA-DRB1 gene may contribute to the clinical heterogeneity of UC between Han and Uyghur UC patients in China. CONCLUSION:HLA-DRB1*04*13*14 and DRB1*08 may contribute to the clinical heterogeneity of UC between Han and Uyghur UC patients.

文摘Developmental dyslexia is a complex reading and writing disorder with strong genetic components. In previous genetic studies about dyslexia, a number of candidate genes have been identified. These include DCDC2, which has repeatedly been associated with developmental dyslexia in various European and American populations. However, data regarding this relationship are varied according to population. The Uyghur people of China represent a Eurasian population with an interesting genetic profile. Thus, this group may provide useful information about the association between DCDC2 gene polymorphisms and dyslexia. In the current study, we examined genetic data from 392 Uyghur children aged 8–12 years old from the Xinjiang Uyghur Autonomous Region of China. Participants included 196 children with dyslexia and 196 grade-, age-, and gender-matched controls. DNA was isolated from oral mucosal cell samples and fourteen single nucleotide polymorphisms（rs6456593, rs1419228, rs34647318, rs9467075, rs793862, rs9295619, rs807701, rs807724, rs2274305, rs7765678, rs4599626, rs6922023, rs3765502, and rs1087266） in DCDC2 were screened via the SNPscan method. We compared SNP frequencies in five models（Codominant, Dominant, Recessive, Heterozygote advantage, and Allele） between the two groups by means of the chi-squared test. A single-locus analysis indicated that, with regard to the allele frequency of these polymorphisms, three SNPs（rs807724, rs2274305, and rs4599626） were associated with dyslexia. rs9467075 and rs2274305 displayed significant associations with developmental dyslexia under the dominant model. rs6456593 and rs6922023 were significantly associated with developmental dyslexia under the dominant model and in the heterozygous genotype. Additionally, we discovered that the T-G-C-T of the four-marker haplotype（rs9295619-rs807701-rs807724-rs2274305） and the T-A of the two-marker haplotype（rs3765502-1087266） were significantly different between cases and controls. Thus, we conclude that DCDC2 gene polymorphisms are associated with developmental dyslexia in Chinese Uyghur children.
文摘Vocabulary knowledge is one of the most important aspects of language development. For bilingual students, early vocabulary development often predicts their future bilingual success. This paper examines early bilingual receptive vocabulary knowledge of ethnic minority children(N=135) from two large ethnic language communities(Uyghur and Kazak) in three national-level povertystricken counties in Xinjiang, China. The children’s bilingual vocabulary knowledge was assessed using translated versions of the Peabody Picture Vocabulary Test-IV(PPTV-IV) in Putonghua(PTH) and their mother tongue(MT) Uyghur or Kazak. Data were analyzed through four General Linear Models(GLM). The analyses showed that both groups scored higher in MT vocabulary knowledge than that in their PTH, although the Kazak students’ MT vocabulary scores were lower than those of the Uyghurs. While gender, age, L1, or residence location were not significant factors in differences across the two groups in PTH, among the Kazak children, the main effect of age was significant in MT;and among Uyghur children, residence location had a significant effect. The two groups also differed in patterns of acquisition in different parts of speech(nouns, verbs, and attributes) with Uyghur children performing strongest in MT and PTH verbs. The findings have important implications for ensuring the quality of early bilingual education among impoverished Chinese minority communities.

文摘To achieve efficient a d compact low-dimensional features for speech emotion recognition,a novel featurereduction method using uncertain linear discriminant analysis is proposed.Using the same principles as for conventional linear discriminant analysis(LDA),uncertainties of the noisy or distorted input data ae employed in order to estimate maximaiy discriminant directions.The effectiveness of the proposed uncertain LDA(ULDA)is demonstrated in the Uyghur speech emotion recognition task.The emotional features of Uyghur speech,especially,the fundamental fequency and formant,a e analyzed in the collected emotional data.Then,ULDA is employed in dimensionality reduction of emotional features and better performance is achieved compared with other dimensionality reduction techniques.The speech emotion recognition of Uyghur is implemented by feeding the low-dimensional data to support vector machine(SVM)based on the proposed ULDA.The experimental results show that when employing a appropriate uncertainty estimation algorithm,uncertain LDA outperforms the conveetional LDA counterpart on Uyghur speech emotion recognition.
文摘Profound cultural changes are transforming the Moslem world of Central Asia, partly as a response to dramatic events in the Middle East and partly to the great economic development in the region. These changes in the Moslem world especially affect the lives of women, since the cultural norms involving the protection of women are an important facet of Moslem life. The goal of this investigation is to show the importance of the ethnographic contribution to anthropological and sociological theory in investigating the new aspects of life in Central Asia. The first concept is the cultural identity of the Uyghur population of China. The second concept is that of Uyghur women, namely, the varied range of women from their role in a conservative, and patriarchal family structure to that of independent actors in a contemporary urban society. We understand that young Uyghur women face a more different set of choices than those of women in other Moslem cultures or in the rest of China. If they identify with their culture as Uyghur and Moslem, their culture restricts their opportunities as Chinese citizens. As students at Minorities University of China （MUC） in 13eijing, the relative freedom of Beijing influences them a great deal. Education and employment are the vehicles for integration into the larger Chinese group. Institutions, such as schools of ethnic studies, and the college competitive exam （the gaokao）, provide opportunities as well as obstacles for Uyghur women as part of the dynamic change in the Moslem world.
文摘As a unique local convention of Islamic proselytizing, Uyghur religious specialists in the present Turpan Basin are using a kind of folk songs ＂qoshaq＂ to organize motifs and materials for their religious sermons. Though the poems are particularly used as religious texts at mosque preaching and other chances of Islamic proselytizing, their contents give insights into the ways of local Uyghurs to understand various daily happenings through the lens of Islamic doctrines. This issue can be taken as a process of the localization of Islamic culture among Uyghurs, therefore, it provides comprehensive pictures on the Islamic ways of local Uyghurs to accommodate their social realities. Through undertaking analyses on the structure, style, contents of the poems, this paper makes efforts to unfold the symbolic landscape of the poems implied, making clear the logic bases of those religious motifs and the attitudes Uyghur preachers had toward social realities.
文摘This paper examines language use inside and out of classroom of Uyghur students from the middle schools for both Han and ethnic minorities in Urumqi, Xinjiang, China. A total of 341 Uyghur students between 12 and 15 years of age, attending 3 middle schools for both Han and ethnic minorities in Urumqi, responded to questionnaires requesting information about their language backgrounds, their use of language at school (inside and out of classroom) and in the wider community, their self-perceptions about their linguistic competence in Uyghur and in Chinese and their attitudes towards Uyghur, Chinese and towards bilingualism. The results, in general, demonstrated a positive attitude towards bilingualism, and there was a trend towards favoring the use of Chinese both inside and outside classroom. The implications of the findings for language policy and planning in education are discussed.

文摘There has been proved the link between the intestinal microbiota composition characteristics and the development of diseases,in particular colorectal cancer,kidney failure,irritable bowel syndrome,intestinal infections,obesity,type I diabetes and metabolic syndrome( MS). Metagenomic studies demonstrated the presence of significant differences in the structure of the intestinal microbiota in populations of Europeans and Asians. In this aspect,the Xinjiang Uygur Autonomous region of China is the most affected district,where substantially the indigenous Uighur,Kazakh and also Han populations is affected. There is an objective need to ascertain the microecological and metabolic status of persons of the indigenous population in Western China,which are in the risk zone. The test for microalbuminuria is reliable method of kidney failure primary stages diagnosis,reflecting the initial stages of vessel pathology and the development of MS. It invariably correlates with an increase of cardiovascular morbidity and mortality. We introduce this screening test for early detection of predisposition to the development of the MS in the example of Xinjiang population for use also in other regions of China.There is a need to carry out the search,selection and analysis of the new strains of probiotics in the Xinjiang from national milk products with lactic acid or other fermented products with the purpose of studying their clinical characteristics. This will have an impact on increasing life expectancy and improving the quality of life of the population of Xinjiang.
