①Location of WD gene in Ch inese: Using pairwise linkage analysis and multipoint linkage analysis method, w e constructed a genetic map of DNA markers within D13q14.2-3 which refined the location of WD gene by restriction fragment length polymorphism and microsatellite polymorphism analysis;②Screen for mutations of WD gene in Chinese people: we detected the structure of 21 exons of WD ge ne in 45 patients from 39 pedigrees by PCR-SSCP(Single strand conformation poly morphism) and PCR-DNA sequencing technology, found a new mutation in exon 5 and nuclcotide sequence analysis showed it is a T insertion. We also conformed the Arg778Leu in exon 8, the highest frequence mutation point in Chinese people, wit h mutation rate 22.8%in total;③Carrier detection and presymptomatic diagnosi s of WD: Based on DNA recombination technology, we peformed successfully the gen e diagnosis in all individuals of 79 families with WD and built up a helpful spe cific enzyme cut method (PCR-Msp1) to detect the carrier and presympomatic patients in Chinese pe ople with WD.

①WD的基因定位研究：通过RFLP及微卫星多态性分析，应用两位点及多位点连锁软件，建立了中国人WD基因在D13q14.2-3区域的精细遗传连锁图谱，从而首次对中国人WD基因进行了精确定位；②WD基因突变研究：应用PCR-SSCP及DNA测序技术，对39个家系45名WD患者进行该致病基因的21个外显子突变筛选，发现WD基因5号外显子存在新的T插入突变，并证实中国人WD基因的突变热点为8号外显子，突变形式为Arg778Leu，其频率为22.8%；③WD的症状前诊断和杂合子检出：应用DNA重组技术对79个家系进行基因诊断，成功地进行了WD的症状前诊断和杂合子检出，并建立了WD的基因筛选的PCR-Msp 1酶切方法。

With the fast development of economic construction of our country, the safety accident in production is outstanding day by day too, the question of safety in production receives the extensive concerns of the country , government and society more and more, directly subordinate organ as the government sets up the mechanism of safety in production rapidly in the whole country, the safety in production has been laid out the government"s important agenda, but as to new organization of safety in production, difficulty and pressure , opportunity and challenge faced are a lot, how to put the thinking in order in work of thousands of strands and loose ends, catch the focal point, give full play to the role of the government"s supervision and management, turn back the passive state of the safety in production rapidly, it is the focal point that this text discusses.

随着我国经济建设的快速发展，安全生产事故也日益突出，安全生产问题越来越受到国家、政府和社会的广泛关注，安全生产机构作为政府的直属机构在全国迅速建立起来，安全生产工作摆上了政府的重要议事日程，但就新的安全生产机构来说，面临的困难和压力、机遇与挑战是很多的，在千头万绪的工作中如何理清思路，抓住重点，充分发挥政府的监督管理作用，迅速扭转安全生产工作的被动局面，是本文讨论的重点。

For example, HLA associations with vitiligo include HLA-DR4 in Caucasian Americans, DR4 and DQW3 in black Americans, DR4 and DR6 in a Dutch caucasoid population, DR7 and DQW3 in north Italians, DR7 in Omanis, DR1 in Hungarians, DRW12 in north Germans, and DW7 in Slovakians. Negative association of DR1, DR3 and DR52 were observed in north Italians. With the DNA typing of HLA, it was found the frequencies of HLA-DRB1〓0701, DQB1〓0201, DPB1〓1601 alleles were significantly increased in Slovak patients and DRB4〓0101 were increased in Dutch patients.

此后发现美国黑人与DR4、DQW3明显相关；匈牙利、德国和斯洛伐克患者中，HLA-DR1、DRW12和DW7抗原频率分别升高；HLA-DR7与意大利患者明显相关，而DR1、DR3则明显降低；荷兰患者中HLA-DR4和DR6抗原频率明显升高，而DR3明显降低；HLA-DR7与阿曼人明显相关，而肢端型又较局限型明显升高。90年代后，DNA分型法用于HLA的研究，发现斯洛伐克患者与HLA-DRB1〓0701、DQB1〓0201、DPB1〓1601明显相关；荷兰患者的DRB1〓0400，〓0901，〓1300、DRB4〓0101、DQA1〓0301、DQB1〓0302，〓0303基因频率升高，而DRB1〓1100、DQA1〓0501降低，但经校正后，仅DRB4〓0101有显著意义。

This "culture of struggle" is being institutionalized in diverse ways, some at quite early stages, others quite developed: in films; in music (the union launched an album that included both traditional labour songs and songs specifically written about the recent events); in art (the new educational center has permanent exhibits and will host temporary exhibits celebrating solidarity and internationalism); in the unique level of resources now dedicated to both education and communicating with the membership (the new education center, the expansion of materials and pamphlets, the growth in the core of locally-based educators, the strengthening and expansion of local union papers); in the mood, style, and content at the Canadian Council, Conventions, and other union meetings; and, of course, in the on-going struggles themselves in collective bargaining and - as with free trade - politically.

这种"文化斗争"制度化正在以各种方式，有的还相当早期阶段，其他相当发达：在电影；音乐（联盟发起了一个专辑，其中包括传统的劳动歌曲和音乐专门写最近发生的事件）；在艺术（新的教育中心，永久展览和临时展览将举办庆祝团结和国际主义）；中的独特的资源水平，现在专门的教育和沟通的成员（新的教育中心，扩大材料和小册子，增长中的核心，当地的教育工作者，加强和扩大当地联盟篇）；人的情绪，风格和内容在加拿大，公约和其他联盟会议；和当然，在正在进行的斗争本身在集体谈判和-与自由贸易-政治。
