【摘要】：调查蒙古斑在维吾尔族婴幼儿中的发生率及消退时间,完善该民族体质人类学资料,探索该民族人种构成特点及演化过程.肉眼观察新生儿身体各部皮肤,用半透明纸拓绘蒙古斑外形轮廓,以重量面积换算法确定蒙古斑的面积.结果表明新疆维吾尔自治区内,不同地区维吾尔族新生儿蒙古斑发生率不同,各地区之间差异显著,从东部到西部呈逐渐减少趋势,平均发生率为46.12%.从东部到西部,蒙古斑面积占体表面积比率逐渐减少,平均比率为0.69%.1岁内蒙古斑消退78.08%,5岁内消退98.71%,未发现蒙古斑对婴幼儿生理产生异常影响,消退后皮肤未出现异常.蒙古斑在新疆不同地区维吾尔族新生儿中的发生率及东西方向的梯度差异,体现了现代维吾尔族可能具有欧罗巴人种血源,欧罗巴人种血源对维吾尔族的掺入是由西部向东部逐渐深入的演化过程.
[Abstract]:Investigation of Mongolia spot in the Uygur infants and the incidence of regression time, improve the national physical anthropology, explore the ethnic ethnic composition characteristics and evolution of the various parts of the body. The skin of newborn eye, extension painted Mongolia spot contour with translucent paper, the weight transfer area algorithm to determine the plaque area. The results show that Mongolia the Xinjiang Uygur Autonomous Region in different regions, different incidence of newborns in Mongolia Uygur spot, significant differences between regions, from the east to the west gradually decreased, the average incidence rate was 46.12%. from the east to the west, Mongolia spot area accounted for surface area ratio decreased, the average ratio of 0.69%.1 years old in Inner Mongolia 78.08% spots, 5 disappeared in 98.71%, not Mongolia spot abnormal effect on infant physiology, subsided after the skin does not appear abnormal. Mongolia spots in different areas of Xinjiang Uygur nationality new The difference between the incidence of children and the gradients between East and West indicates that the modern Uygur may have Europa race source, and Europa ethnic blood source's evolution to Uygur is from west to East.
