新疆维吾尔自治区内不同地区维吾尔族人耵聍的遗传多态性

Ceruminous Genetic Polymorphism of the Uighur Adults in Different Parts of Xinjiang Uighur Autonomous Region

对新疆维吾尔自治区内七个地区6592名汉族成年人(18-45岁)和5887名维吾尔族成年人(18-45岁)不同类型耵聍的表型频率进行了调查。结果显示,新疆维吾尔自治区内不同地区汉族成年人不同类型耵聍的表型频率无显著差异(P>0.05),与我国北方汉族相同。维吾尔族成年人湿型耵聍有较高的频率,平均为58.13%,介于欧罗巴人种和北亚蒙古人种之间。同一地区内,维吾尔族男性和女性间湿型耵聍频率无显著差异(P>0.05),不同地区维吾尔族人群之间湿型耵聍频率有极显著差异(P<0.001)。湿型耵聍频率最低为东部的哈密市(40.99%),最高为西部的喀什市(88.53%),且呈从东到西逐渐增加的趋势。新疆地区的维吾尔族人群的耵聍类型表型频率呈现一定的多态性,某一地区的耵聍类型表型频率不能代表全体维吾尔族。维吾尔族耵聍不同类型的表型频率介于欧罗巴人种和北亚蒙古人种之间的特点可能有助于揭示现代维吾尔族的族源、人种构成、人种特点及演化过程。

Investigated different type cerumen phenotype frequency of 5887 Uighur adults （18-45 years old, male 2902, female 2985） and 6592 Han adults 08-45 years old, male 3273, female 3319） in seven different parts of Xinjiang Uighur Autonomous Region. The results showed that different type cerumen phenotype frequency of Han adults in Xinjiang different parts have no significant difference （/＇〉 0.05）. The same with the Han nationality in North China. There is a higher incidence （average 58.13%） of wet-cerumen among Uighur adults, between the Europa and the North Mongoloids. There isn＇t significant difference of wet-cerumen phenotype frequency between men and women in the same region （P〉 0.05）. There is significant differences of wet-cerumen phenotype frequency among groups in different regions （P〈0.001）. The lowest incidence of wet-cerumen is Hami （40.99%） in the eastern region, the highest incidence of wet- cerumen is Kashgar（88.53%） in the western region and the incidence of wet-cerumen from east to west is a growing trend. We can see that phenotypic characteristics of cerumen types in a certain region of Xinjiang Uighur population can not represent all the Uygur population. Uighur ethnic has a certain Europa blood. The results will help to reveal the origin, ethnic composition, ethnic characteristics and evolution of modern Uighur.
