Genomic diversity and post-admixture adaptation in the Uyghurs

Population admixture results in genome-wide combinations of genetic variants derived from different ancestral populations of distinct ancestry, thus providing a unique opportunity for understanding the genetic determinants of phenotypic variation in humans. Here, we used whole-genome sequencing of 92 individuals with high coverage (30–60×) to systematically investigate genomic diversity in the Uyghurs living in Xinjiang, China (XJU), an admixed population of both European-like and East-Asian-like ancestry. The XJU population shows greater genetic diversity, especially a higher proportion of rare variants, compared with their ancestral source populations, corresponding to greater phenotypic diversity of XJU. Admixture-induced functional variants in EDAR were associated with the diversity of facial morphology in XJU. Interestingly, the interaction of functional variants between SLC24A5 and OCA2 likely influences the diversity of skin pigmentation. Notably, selection has seemingly been relaxed or canceled in several genes with significantly biased ancestry, such as HERC2–OCA2. Moreover, signatures of post-admixture adaptation in XJU were identified, including genes related to metabolism (e.g. CYP2D6), digestion (e.g. COL11A1), olfactory perception (e.g. ANO2) and immunity (e.g. HLA). Our results demonstrated population admixture as a driving force, locally or globally, in shaping human genetic and phenotypic diversity as well as in adaptive evolution.     

关于体育院校武术专项学生个性特征的研究

随着运动训练水平的提高,心理训练成为现代竞技体育训练的重要组成部分。体育院校武术专业学生是未来武术发展的后备人才,针对其个性心理特征的研究与培养,有利于我国武术项目的健康发展。通过研究得出,武术专项学生的个性心理特征的主要品质为独立性、自觉性、思维性,第二品质为顽强性。体育院校的武术系学生与运动队队员略有差异。文章提出针对运动队和武术系学生的不同培养目标和特点,应加以区别对待和培养,推动武术项目科学的可持续发展。     

罕见的元代丝织品

1976年，内蒙古集宁市东南30公里，察右前旗巴音塔拉公社南5公里处发现一批窑藏元代丝织品。此地原为金集宁县，元初时升为路。这一窑藏东北150米处是文宣王碑，居集宁路故城内。窑中几件丝织品，无论是光泽，弹性，还是抗折性都比较好，
