农业生物多样性大数据平台建设研究和展望

农业生物多样性是指直接或间接用于粮食和农业的动物、植物和微生物的多样性和变异性,包括作物、家畜、林业和渔业等。它位于整个农业系统的底层,是农业生产信息化的重要内容,也是国家战略资源和国家安全的重要基础。国内外相关组织机构和项目积累了很多的资源和建设经验,但是仍然存在资源零散分布、缺乏顶层设计、元数据标准规范应用不足、平台之间的数据交互不够、数据的快速实时响应比较困难、高端农业智库及其资源平台建设薄弱等问题。为了更好地推动我国农业生物多样性大数据平台的研究和开发工作,本文着重从科学数据平台（基础数据平台、作物数据平台、家畜数据平台、林业数据平台、渔业数据平台、传统文化知识平台、智库平台和评估指标）和相关信息化基础资源对象（术语库、主题词表、元数据标准规范、本体和科研工作流）来梳理农业生物多样性大数据的国内外研究和应用进展,并从基础层、资源层、组织层和应用服务层等四个层次来提出农业生物多样性大数据平台的顶层建设框架,还针对当前现状和问题提出了建议和展望,为我国农业生物多样性大数据平台建设和资源共享服务提供参考。</p

人肝癌裸鼠移植瘤株HHC_4、HHC_(15)的分子病理学研究

厦门市同安地区已成为中国肝癌死亡率第二的高发区。作者对由来自该地区肝癌病人的人肝癌所建立的裸鼠移植瘤株(HHC_4、HHC_(15)细胞所提取的dnA进行分子生物学研究。应用PCr方法发现了HHC_4、HHC_(15)癌细胞dnA都有HbVdnA整合。通过dnA测序,证明了HHC_4dnA有P53基因第250密码子的C→A突变;HHC_(15)有P53基因第249密码子的g→T突变。这为本地区肝癌死亡率与高HbV感染率和/或黄曲霉素b_1在食品中高污染率的关系提供有力的分子病理学证据

The Morphology of the Primary Dental Arch of Chinese Children in Shijiazhuang-City Part-I: Research concerning the size of the primary tooth crown, primary dental arch and the condition of primary occlusion

The purpose of this study was to investigate the size of the primary tooth crowns, primary dental arches, standard values and frequency distribution of primary occlusion in Chinese children. With the cooperation of a kindergarten in Shijiazhuang-city, China, the dental plasters from 55 children (36 boys and 19 girls, age range from 3-6 years old) with normal primary occlusion were collected. Because of different growth rates of the children, these children were divided into two groups, one comprising children less than 5 years old and the other of 5 years old or older. According to the method that the Japanese Society of Pediatric Dentistry reported, the data were statistically analyzed and compared to Japanese children. The results were summarized as follows: 1. Except lower primary lateral incisors, the values of the mesio-distal width of primary crowns of each tooth were significantly larger for boys than for girls in all tooth types. Also the Chinese children were inclined to show smaller mesio-distal tooth crown width than those of the Japanese children in all types of teeth. 2. Compared with the Japanese children, the Chinese children were inclined to show smaller primary dental arch length both in the maxilla and the mandible. But in the senior group, the Chinese girls were inclined to show smaller primary dental arch width than their Japanese female counterparts. On the contrary, the Chinese children tended to show larger dimensioned primary dental arch height than those of the Japanese children. 3. Though spaces between teeth (primate and growth spaces) were found in the Chinese children, the frequency was lower than that of the Japanese children. 4. The frequency of terminal plans in the Chinese children was 41.8% in the vertical type, 6.4% in the distal-step type and 51.8% in the mesial step type. 5. The primary canines occlusal relationship in the Chinese children was 63.1% in type I, 13.6% in type II and 23.7 in type III
