Polymorphism of the ABO blood group genes in Han, Kazak and Uygur populations in the Silk Route of northwestern China

Genetic polymorphism in the ABO blood group gene of Han, Kazak and Uygur populations inhabiting the most northwestern part of China was investigated using polymerase chain reaction-based techniques. The present study enrolled 43 healthy unrelated Han, 37 Kazak and 59 Uygur volunteers. The allele in A1 blood group is distinguished A0101 and A0102 in difference of nucleotide position 467. The A0101 allele is more frequent in Caucasian and the A0102 allele is characteristic in Mongoloid. It must be notable that A0201 in the A2 group (with a single base deletion at nucleotides 1059 to 1061) which was characteristic of Caucasian was observed in Kazak and Uygur populations but not in Han. Further, 00201 (with no nucleotide deletion at 261 and three nucleotide differences), which is frequent in different races including Caucasian except for Mongoloid, was detected also in Kazak and Uygur populations. The frequencies of B0101 in Kazak, Uygur and Han were comparable to those of other Asian populations but higher than those of Caucasian populations. Collectively, these results reveal that the allele frequencies of Kazak and Uygur at the ABO blood group locus are an intermediate between those of Mongoloid and Caucasian, suggesting the admixed feature of Kazak and Uygur with Mongoloid and Caucasian.     

中国汉族人群APOE等位基因频率的初步研究

载脂蛋白Ｅ（ａｐｏｌｉｐｏｐｒｏｔｅｉｎＥ，ＡＰＯＥ）基因是一个多功能基因，除调节脂类及脂蛋白代谢之外，近年来还发现它与Ａｌｚｈｅｉｍｅｒ病及Ⅲ型高血脂症等病之间有密切关系。为对上述疾病进行病因学研究，作者采用一步法ＰＣＲ技术对４３８名无亲缘关系的中国汉族健康受试者的ＡＰＯＥ基因进行分型，并计算其基因频率分布，结果表明，中国治疗人群ＡＰＯＥ３种等位基因的频率分别为：Ｅ２＝０．０４００，Ｅ３＝０．８     

川南苗族体质特征的调查研究

对合江县川南苗族 2 0 7例 (男 113,女 94 )青壮年进行 73项活体测量 ,结果显示 :川南苗族身材矮小 ,男女性身高平均为 15 4 5 6cm和 14 3 89cm ,83%受检者身高分类属矮或很矮 ;体部垂直高度均偏小。川南苗族偏瘦弱 ,其体部宽度、深度测量及围度测量均偏小 ,体质稍差。川南苗族头长偏小 ,头宽与头高相对较大 ,故 6 8%以上受检者为圆或超圆头型、阔头型也较狭头型为多、 75 %以上为高头型 ;面高与面宽均小 ,面高尤甚 ,75 %以上的受检者属阔或超阔面型 ;鼻部测量值均小 ,6 0 %的个体属中鼻型 ,属狭或超狭鼻型较阔鼻型的略多。两性间各项测量差异显著 ,但具共同体质特征。三年龄组比较青年组头面部与胸部测量值较成年组与壮年组小 ,表明其发育尚未终止 ,但因长度与宽度或长度与高度、宽度与高度均平行增长 ,故头型、面型、鼻型等均无显著差异而三组保持共同特征     

正常新疆维吾尔族人头发的扫描电镜观察

本文应用扫描电子显微镜对新疆维吾尔自治区南部地区12名(6女,6男),年龄在17岁至20岁之间的维吾尔族人不同部位的头发进行了初步观察研究。发现头发呈圆柱形,毛小皮鳞片呈叠瓦状。但鳞片排列方式、紧密度及形态因个体及部位不同而异。根据毛小皮排列方式可分为三型:即平行型,交错型及混合型,又根据毛小皮排列的紧密度分为密型和疏型。毛干的直径因个体不同大致可分为粗发和细发,粗发毛小皮单位距离内的层数大于细发,毛小皮排列多呈平行线。细发毛小皮排列多呈交错、混合型。     

苗族成人体型研究

Polymorphism of human leukocyte antigen-DRB1, -DQB1, and -DPB1 genes of Shandong Han population in China

In the present study, polymerase chain reaction-sequence-based typing (PCR-SBT) was used to analyze human leukocyte antigen (HLA)-DRB1, -DQB1, and -DPB1 alleles of 98 unrelated healthy Shandong Han individuals. A total of 60 alleles, in which 28 in DRB1, 15 in DQB1 and 17 in DPB1 were found. Among the 28 detected DRB1 alleles, DRB1*150101, DRB1*070101, DRB1*090102, DRB1*120201, and DRB1*080302 were commonly observed, with frequencies of 16.3%, 11.2%, 10.2%, 8.2%, and 5.6%, respectively. The most predominant DQB1 allele was DQB1*030101/0309 with the frequency of 20.4%, followed by DQB1*0201/0202 (14.8%), DQB1*0602 (14.3%), DQB1*030302 (12.2%), and DQB1*060101/060103 (10.7%). Of the 17 detected DPB1 alleles, DPB1*0501 was the most frequent allele with the frequency of 37.2%. DPB1*020102 (18.4%), DPB1*040101 (11.2%), DPB1*0402 (7.1%), and DPB1*1701 (6.6%) were also very frequent alleles. A total of 53 estimated DRB1-DQB1 two-locus haplotypes were observed in Shandong Han population, of which DRB1*150101-DQB1*0602 was the most predominant, followed by DRB1*090102-DQB1*030302, DRB1*070101-DQB1*0201/0202 DRB1*120201-DQB1*030101/0309, and DRB1*080302- DQB1*060101/060103. The distribution of the HLA class II alleles and haplotypes frequencies as well as the dendrogram showed that the Shandong Han population belongs to the northern group of Chinese. The data have implications for anthropological studies and disease associations.

79例广东汉族人群HLA-Cw及其KIR分析

目的：了解HLA—Cw与相应刺激性KIR（杀伤细胞免疫球蛋白样受体）和抑制性KIR在广东汉族人群中的分布。方法：对79例广东汉族骨髓移植供者，以DNA技术检测HLA-Cw和KIR表型。根据对KIR识别的特异性，将HLA-Cw分为HLA-Cw^lys.HLA-Cw^asn，分析个体HLA-Cw与相应刺激性或抑制性KIR的识别情况。结果：本组人群中，HLA-Cw^lys、HLA-Cw^asn的频率分别为26．6％、97．5％。表达KIR2DL1而无栩应配体者62．0％，表达2DS1而无相应配体者15．1％。27．8％表达HLA-Cw^asn而不表达相应KIR。25．3％、55．6％有抑制性HLA-Cw^lys或HLA-Cw^asn配体受体对，1．3％和14．0％的个体单独表达刺激性HLA-Cw^lys扣或HLA-Cw^asn配体受体对。15．1％的个体表达KIR2DS1而不表达HLA-Cw^lys。结论：在广东汉族人群中，存在KIR表型与自身HIA表型分离现象。抑制性HIA-Cw-KIR配对表达高于刺激性配对，约1／5单独表达刺激性HLA-Cw—KIR配对。
