  • 简介:AbstractObjective:To elucidate the epidermal melanocyte distribution according to sex, age, and body part with the goal of providing benchmark data for the diagnosis and therapeutic effect evaluation of pigmentary skin diseases.Methods:Epidermal melanocytes and keratinocytes were assessed using direct immunofluorescence staining, and the melanocyte density and epidermal thickness were calculated. The obtained data were statistically analyzed using SPSS Version 20.0 software. An independent-samples t test was used to compare the data between two groups, while data among three or more groups were compared by one-way analysis of variance. Data correlations were evaluated using Pearson correlation analysis.Results:Melanocytes were uniformly distributed among the keratinocytes in the basal layer, and the average ratio of melanocytes to keratinocytes was 1:7. Among them, the ratio in males was 1:6.5 and that in females was 1:7.4, with no significant difference (P= 0.127). The melanocyte density gradually declined as age increased; the ratio was 1:5.8 before 50 years of age without an obvious downtrend. The average melanocyte density was 1:7.9 within 51 to 65 years of age and 1:8.5 at >65 years of age, and the difference was statistically significant (P < 0.01). Obvious differences were found in the melanocyte density among different body parts; in descending order, these densities were as follows: face (1:4.0) >neck (1:5.1) >hip (1:5.7) >upper limb (1:7.4) >lower limb (1:8.3) >lower back (1:9.2) >thorax and abdomen (1:9.9). The melanocyte density was not related to the epidermal thickness.Conclusion:The melanocyte density showed a declining trend with age and significantly changed after 50 years of age. The melanocyte density was associated with body part; specifically, the density in the face, neck, and hip was higher than that in the limbs and torso. However, the melanocyte density was not associated with sex or epidermal thickness.

  • 简介:组G的正常霍尔亚群N是有它有它的索引的顺序coprime的正常亚群。Schur-Zassenhaus定理声明每正常霍尔亚群有补充亚群,那是也形成G的亚群的一套coset代表H。在这份报纸,我们在场与至少一正常霍尔亚群测试组的同晶型的一个框架,当组们是被给时乘法表。建立框架,我们首先观察到Schur-Zassenhaus定理的一个证明是建设性的,并且提出为以正常部分和补充部分的semidirect产品,和同晶型的联系行动的严峻的同晶型的一个必要、足够的条件。当正常亚群是abelian时,我们然后集中于盒子。由Le胆量(STACS2009)利用有限的组和一种技术的表示理论的基本事实,我们首先让有效同晶型当补充围住发电机的数字时,测试算法。当补充亚群是基本的时,为诉讼,abelian,它未必做围住发电机的数字,我们获得由归结为概括法律同晶型问题测试算法的多项式时间同晶型,它问二线性subspaces是否是直到坐标的排列的一样。后者的一个答案能被温和扩展获得单身地指数(在坐标的数字)为代码同晶型问题的时间算法最近由Babai等发展了。(苏打2011)。Enroute到获得上述减小,我们在有限的组的表示理论学习下列计算问题:给二个代表并且在\mathbbZpd\mathbb上的组H{Z}_p^d,p一个素数,决定是否在那里存在自守:HH劝诱的表示=并且是相等的,及时poly(|H|,pd)。
