太行山猕猴掌骨和跖骨体质量的性差与排序

目的:了解太行山猕猴掌(跖)骨体质量性差和排序.方法:测量25例掌骨和27例跖骨体质量.运用SPSS13.0统计软件对掌(跖)骨体质量性差和排序进行方差分析.结果:掌(跖)骨体质量性别差异有统计学意义,两侧之间则没有统计学意义.使用不同的方法各掌(跖)骨体质量的排序不同.掌骨体质量均值顺序是3>2>4>5>1.在侧别和性别之间无差异;跖骨体质量均值排序在性别之间有差异,雄性是3>4>2>5>1,雌性是3>4>2>1>5.结论:太行山猕猴掌(跖)骨体质量存在性差,各掌(跖)骨体质量的排序也有一定性差,此性差产生的原因与基因调控、出生前性激素水平及出生后异速生长速度等有关.     

人类指(趾)长比与运动能力关系研究的现状

BACKGROUND: At present, it is a hot spot to study the relationship between digit or phalange length ratios and athletic ability. However, the results from various studies cannot be verified each other because there are controversies about the research objects and the research technique in the area. Therefore, it is necessary to point a right direction for the research in this field. OBJECTIVE: To explore the relationships of digit and phalange length ratios to athletic ability and the existing problems by literature search strategies and logic thinking methods. METHODS: A computer-based online search was conducted in Elsevier Science-direct, PubMed, EM, CNKI, and CJFD databases by using the key words of “digit length ratio, 2D:4D, phalange length ratio, athletic ability” from 1990 to 2015. The language was limited to both Chinese and English. 358 relevant articles were screened, and 42 eligible articles were included finally. RESULTS AND CONCLUSION: Currently, studies show that there are some relationships between digit phalange length ratio or phalange length ratio and athletic ability. There are controversies about the research results due to the diverse study methods and techniques. It is necessary to define the digit phalange length ratio or phalange length ratio in the human study. The most advanced techniques should be considered to reduce the measurement bias. Moreover, multi-angle, multi-level studies should be performed to reveal the relationship of digit phalange length ratio or phalange length ratio to athletic ability. Human digit phalange length ratio or phalange length ratio, particularly 2D:4D can reflect the aerobic exercise capacity of athletes. 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程     

大学生手长、手宽与身高的回归分析

目的 ：探讨大学生手长、手宽与身高的相关性。方法 ：身高和手的度量取自郑州工商大学商学院随机抽取的650名研究样本，其中男性327名，女性423名。对测量数据进行相关和回归分析。结果 ：男性和女性的手测量值与身高呈显著正相关（r=0.319～0.793, P<0.01）。回归模型的估计标准误差为±3.744～±5.902 cm。仅用手长建立的简单线性模型得出男女平均SEE最低，为±3.744～±4.168 cm。结论：手长是估计身高的最佳指标之一。
