The purpose of the work is to investigate the frequencies and polymorphisms of HIV-1 resistant CCR5delta32,CCR2b-64I,SDF1-3′A alleles in Chinese Dai and Chingpaw populations.Whole blood samples from 101 Dai subjects and 113 Chingpaw were collected randomly and their genomic DNA were extracted with QIAgen Blood Kits.Allelic frequencies were identified by PCR-RFLP analysis.Allelic polymorphisms in Dai population or Chingpaw population and both sexes in the samples were analyzed by χ2 test.

为了调查HIV-1感染相关的等位基因CCR5△32、CCR2b-64I、SDF1-3′A在我国云南省德宏州傣族景颇族人群中的频率和多态性分布，此课题以101例傣族和113例景颇族人群为研究对象，应用PCR、PCR-RFLP(聚合酶链反应-限制性片段长度多态性)分析方法进行检测，计算突变基因频率；并对其群体分布、性别分布进行统计学分析。

The frequencies of CCR5delta32,CCR2b-64I,SDF1-3′A alleles in Dai population were 0.0000,0.2130,0.2030,respectively;The frequencies of CCR5delta32,CCR2b-64I,SDF1-3′A alleles in Chingpaw population were 0.000,0.1637,0.1770,respectively.Distributions of the CCR2b-64I,SDF1-3′A alleles among the both populations were in accordance with Hardy-Weinberg equilibrium.No statistical difference was found in the allelic frequencies of both CCR2b-64I and SDF1-3′A between male and female individuals.

结果表明，中国傣族景颇族人群中未发现CCR5△32等位基因突变；傣族CCR2b-64I、SDF1-3′A基因突变频率分别为0.2130和0.2030，景颇族CCR2b-64I和SDF1-3′A基因突变频率分别为0.1637和0.1770；与中国汉族人群相比较，傣族和景颇族中SDF1-3′A突变频率较低（P值分别为0.0322和0.0021）；两个民族的CCR2b-64I和SDF1-3′A等位基因群体分布符合Hardy-Weinberg平衡，在性别之间分布无显著差异。

白梭梭-梭梭群落的白梭梭种群在所研究的尺度(0～50m)上由聚集分布向均匀分布转变，梭梭种群呈聚集分布；白梭梭与梭梭的种间关系在空间上呈负相关、不相关和正相关变化序列。

While in Ass.haloxy persicum-H.ammodendron communities, either Haloxylon ammodendron population or Haloxylon persicum population, the spatial pattern was also congregative in 0~50m scales.While sometimes there was a transition from congregative pattern to regular pattern between them. There was a negative or positive, no relation and negative relation change series between Haloxylon ammodendron and Haloxylon persicum. In Ass.
