Plain Language Summary 是 British Journal of Dermatology 期刊为提高皮肤病患者的健康认知力实施的一项新举措,自2014年1月起开始出版。一篇 Plain Language Summary 通常以通俗精炼的语言概括了晦涩的医学文章内容,主要 面向没有系统学习过医疗知识的大众,以普及相关医学研究及进展 。 皮肤癌是在浅肤色人群中发病率较高的一类常见癌症类型,本期精选内容将为您介绍全科医师在皮肤癌护理中扮演的角色及皮肤癌预防项目需要特别关注的群体类别。 2014 年6月期精选内容: 1. 全科医师在皮肤癌护理中的当前和未来角色:基于 268 名全科医师的评估 皮肤癌 在浅肤色人群中的发病率日益上升。不但给患者造成负担,这种上升趋势也给皮肤科医师的诊所和不同国家的医疗保健费用造成了负担。黑色素瘤是最小、但是更为致命的皮肤癌类型之一。非黑色素瘤皮肤癌( NMSC )代表了更常见、但是致死性更低的皮肤癌类型:基底细胞癌( BCC )、鳞状细胞癌( SCC ),以及癌前(尚未癌变)病变:光化性角化病( AK )和鲍文氏病( BD )。 这篇荷兰研究旨在评估全科医师对他们在皮肤癌预防、诊断与治疗中的角色的态度以及他们对教育的需求 。 研究人员调查了 2010 年到 2012 年期间由荷兰的一个地区的全科医师填写的 268 份包含 36 个问题的调查问卷。根据结果, 超过50%的全科医师需要额外的皮肤癌教育。全科医师通常自己治疗光化性角化病,主要是利用冷冻疗法。超过50%的全科医师愿意在接受额外的培训后治疗低风险的基底 细胞癌,但是熟悉基底细胞癌治疗指南的全科医师少之又少。 大多数患有高风险皮肤癌的患者都被转介给皮肤科医师治疗。很少有全科医师进行全身检查,而不是只检查某一处皮肤区域。很多全科医师都会告诉其患者皮肤癌发病的风险因素。作者得出的结论是,大多数全科医师都愿意扩展他们在皮肤癌护理中的角色,但是需要更多的培训,并且应该鼓励使用治疗指南。那些愿意扩展其角色的全科医师应致力于改善其对皮肤肿瘤的临床诊断、低风险皮肤癌和癌前病变的治疗,以及预防工作。 2. 遵循防晒医嘱相关的因素:来自皮肤科会诊的 2215 名患者的全国横断面评价结果 皮肤癌 是最常见的癌症类型,受到来自太阳的紫外线( UV )辐射是可预防的主要原因。但是,旨在宣传防晒的活动常常不能带来行为的长期变化。 这项法国研究旨在确定哪些皮肤科患者最不可能遵医嘱采取防晒措施,并将人们的知识与他们的行为进行比较 。领取了防晒处方的 2215 名皮肤科患者完成了一份探讨四个领域的问卷调查:防晒行为(他们采取什么防晒措施)、防晒知识(他们对防晒方法了解多少)、紫外线辐射的水平(他们在阳光下待多长时间)以及紫外线相关风险的知识。最不可能采取防紫外线措施的是 20 岁以下和 64 岁以上的男性。问卷调查显示,相同的群组最不了解防晒方法以及阳光照射相关的风险。 20 到 64 岁之间的女性最可能了解紫外线辐射的潜在危害,并且最可能采取防晒措施,她们认为使用高防晒系数的防晒霜和穿防护服是最有效的防晒措施。 可以理解,对阳光照射的危险越了解的人,最可能使用防晒方法。但是研究发现相同的人群在阳光下待的时间更长。这项研究表明了紫外线辐射、紫外线相关风险的知识、防晒建议的知识以及防晒行为之间的复杂关系。作者得出的结论是, 未来的皮肤癌预防项目应该重点关注很少采取防晒行为和受到高强度紫外线辐射的特定人群。 你知道吗? 补充维生素D可以有效治疗斑秃 。 本期其他亮点 是来自土耳其的学者实验对比发现维生素 D 水平越低,斑秃患者会产生越严重的脱发,这与两者对毛发周期的影响作用有关。 点击查看详细内容 《英国皮肤病学杂志》( British Journal of Dermatology ) 编辑 : Alex Anstey, Newport, UK 2014 年影响因子 : 4.275 ISI JournalCitation Reports © Ranking:2014: 6/62 (Dermatology) 欢迎点击阅读更多本期 Plain Language Summary 内容: http://onlinelibrary.wiley.com/enhanced/doi/10.1111/bjd.13086/

最新研究发现即使避开阳光,紫外线损伤仍会持续数小时
medjaden 2015-4-7 14:37
在众多癌症类型中,皮肤癌是最常见的类型之一。美国人一生中患皮肤癌的风险几率高达20%。大多数皮肤癌是由太阳光紫外线直接损伤DNA,引起C→T和CC→TT突变,形成环丁烷嘧啶二聚体所造成。 传统认为,环丁烷嘧啶二聚体中胞嘧啶或5’甲基胞嘧啶迅速脱氨基形成尿嘧啶或胸腺嘧啶是皮肤癌基因突变的机制;而且普遍认为一旦离开太阳光,紫外线的损伤就会停止。 但是,华盛顿大学的学者在《科学》杂志3月份刊出的最新研究结果证明,事实并非如此。即使避开阳光,紫外线通过其他途径,仍然持续损伤皮肤细胞的DNA。这一重大研究结果揭示了黑色素瘤的形成机制。 美捷登:Mike 原文信息 Chemiexcitation of melanin derivativesinduces DNA photoproducts long after UV exposure Science20 February 2015: Vol. 347 no. 6224 pp. 842-847 Mutations in sunlight-induced melanomaarise from cyclobutane pyrimidine dimers (CPDs), DNA photoproducts that aretypically created picoseconds after an ultraviolet (UV) photon is absorbed atthymine or cytosine. We found that in melanocytes, CPDs are generated for 3hours after exposure to UVA, a major component of the radiation in sunlight andin tanning beds. These “dark CPDs” constitute the majority of CPDsand include the cytosine-containing CPDs that initiate UV-signature C→T mutations. Dark CPDs arise when UV-induced reactive oxygen andnitrogen species combine to excite an electron in fragments of the pigmentmelanin. This creates a quantum triplet state that has the energy of a UVphoton but induces CPDs by energy transfer to DNA in a radiation-independentmanner. Melanin may thus be carcinogenic as well as protective against cancer.These findings also validate the long-standing suggestion that chemicallygenerated excited electronic states are relevant to mammalian biology. 原文链接: http://www.sciencemag.org/content/347/6224/842.abstract 美捷登版权www.medjaden.com欢迎转载,转载请勿修改内容 欢迎关注我们的微信

茶:世界最佳饮料
热度 24 何裕民 2015-4-2 16:54
早在20世纪80年代,国外好事者作了一个比较研究,研究各大国的健康生活方式。结果,苏联以居住条件居首(80年代莫斯科人居住条件良好);英国人以衣着领先(绅士风度);中国则以饮为佳(中国茶,世界公认最健康的饮料)。中国是茶的故乡,茶是地地道道的中国“国粹”,茶与咖啡、可可同为世界三大饮料,但茶最为健康,最符合保健需求。 名闻遐迩的茶多酚 茶叶中主要包括有生物碱、茶多酚、糖类、有机酸、芳香物质、维生素、矿物质等多种化学成分;最重要的有效成分就是茶多酚,含量较高的茶叶中,其可占干重的20%~35%。茶多酚是以儿茶素为主体的多酚类化合物,是一种抗老防衰、增强机体免疫效应的抗氧化剂,不但可以防止动脉粥样硬化和心血管疾病,而且具有防癌功效。 茶是防癌抗癌佳品,多年来已被各国医学专家所证实。尤其是未经发酵的绿茶,抗肿瘤的效果最显著,对于肺癌、皮肤癌、子宫颈癌等都有良好的效果。 茶的防癌抗癌作用与其含有茶多酚有关。研究认为,茶多酚可减弱自由基对DNA的损伤,终止连锁反应,从而防止DNA损伤及细胞癌变;有效阻断亚硝胺类在体内形成,以抑制亚硝基化合物的合成;提高机体免疫力;甚至可直接抑制癌细胞生长,杀死癌细胞。 动物实验表明:以二甲基肼诱发的肠癌为模型,茶多酚可抑制变性隐窝病灶的形成,从而减少大肠肿瘤发生率,表明其有预防作用。临床研究结果显示,茶多酚作为一种化疗辅助药,对放化疗患者的正常细胞数有明显的保护作用。 美国科学家对膀胱癌的研究,证实了绿茶提取物能有效遏制癌肿发展,同时不损害健康细胞的功能。绿茶提取物能抑制癌细胞侵入健康组织、阻止肿瘤扩散。癌细胞具有“侵略性”,而绿茶提取物打破了它“侵略”的路径,能限制癌细胞扩张,使其“局部化”。此外,它还能使癌细胞加快老化。 饮茶方法有讲究 饮茶虽好,但方法有讲究,注意饮茶方法,可以更好地发挥茶的保健作用。 1.不宜空腹饮茶:空腹喝茶,茶水直入脘腹,有如“引狼入室”,会出现心慌、尿频等不良反应,还会影响人体对各种营养素的吸收。 2.不宜饭前饭后饮茶:饭前饮茶会冲淡消化液并降低食欲。饭后喝茶,会延长食物消化时间,增加胃的负担。还有研究发现:茶叶中含有大量单宁酸,如果饭后马上饮茶,食物中的蛋白质、铁质与单宁酸很容易发生凝结,会减少对蛋白质、铁质的吸收,影响器官的多种生理功能,还容易引发缺铁性贫血。 3.饮茶量要适当:不宜大量饮浓茶,否则可使心跳加快,血压升高,引起失眠等。失眠、溃疡病患者等不宜多饮。一般健康成年人,平时有饮茶习惯的,每日饮茶量应在l2~l5克之间,以分3~4次冲泡为宜。 4.辨体质饮茶:如属于寒凉体质或疾病,可饮用红茶;属于温热体质者,宜多饮用绿茶;而肥胖病、高血脂人群,宜选用乌龙茶等。 5.饮茶要学会因时制宜:茶有寒凉温热之分。春夏季,宜多饮绿茶类偏寒性的茶;秋冬季节,多饮乌龙、红茶等偏温性的茶。 6.莫被茶饮料迷惑:现很多商家深谙消费者心理,市面上各种所谓的“健康饮品”的茶饮料种类繁多,特别受年轻消费者的喜爱。但其与茶绝非一回事,代替不了天然茶。试想一下,本色的茶怎么可能是甜的呢?茶饮料中有多少茶呢?能在茶饮料中喝出茶的健康吗?做成饮料,难免添加了各种防腐剂、色素、甜味剂等,只能让你离健康更远。 总之,茶是饮料,亦为精神享受;茶作为一种药物,可清心明目,防癌抗癌,阻击多种慢性病;故学会饮茶,大有好处。 药茶文化奥妙无穷,值得我们去进一步探索和创造。 本人现已开通微信公共账号,在微信公众号中搜索“何裕民”即可,欢迎关注,也可以扫一扫二维码:

红棕发色素增加患皮肤癌风险
zhpd55 2012-11-5 17:59
红棕发色素增加患皮肤癌风险
据《科学美国人》网站 2012 年 11 月 4 日 转载《 自然》( Nature )杂志 网站 2012 年 10 月 31 日 发表的一篇文章 —— Redhead pigment boosts skin-cancer risk ( 红棕发色素增加皮肤癌风险 )。动物实验( Ginger' mice )发现,即使没有 接触任何超强辐射,使用红棕色染发素的小鼠更容易患黑色素瘤。 已经有研究结果显示,红头发的人更容易患皮肤癌,但这种情况可能并不完全是晒太阳所致。白皙的皮肤 , 红头发的人都知道 , 有时是通过痛苦的经历 —— 他们更容易遭受太阳紫外线的伤害,包括晒斑、皮肤老化和患皮肤癌的风险更高等。但最新发表在 《 自然》杂志的一项研究表 明 , 老鼠使用红色素染发,对于诱发黑色素瘤有关。美国波士顿麻省总医院( Massachusetts General Hospital in Boston )的癌症生物学家,也是此研究项目的负责人 David Fisher 说: “ 有一些红头发的遗传因素 , 也有为了时尚而表现出的致癌因素,与太阳紫外线照射无关,这意味着对紫外线的屏蔽将是不够的。 ” 与深色皮肤的人相比 , 那些拥有白皙皮肤、满脸雀斑和红头发的人会产生一种不同形式的黑色素。 红黄色形式的色素也叫做褐黑素( pheomelanin )与皮肤颜色深的形式即真黑素( eumelanin )相比较,有效保护皮肤免受紫外线损伤的功能更差,这种差别是由 黑素皮质素受体 1 基因 (melanocortin-1- receptor gene, MC1R ) 突变引起的。但是,有多年迹象已经表明 , 紫外线照射可能不会完全导致红头发人的黑素瘤风险。 David Fisher 和他的团队希望研究增加风险的分子背景。研究人员观察了有着橄榄色皮肤、姜黄色和白化着色小鼠模型的黑素瘤发展。最后一批有相同的遗传背景 , 但却缺乏必要的合成黑色素酶的黑皮肤老鼠。研究人员还会调整每组实验小鼠的基因,使其更容易诱发良性痣 , 但是这也很有可能就是发展为黑色素瘤的第一步。研究人员计划将实验小鼠暴露在紫外线照射之下,监控其黑色素瘤发展差异。但在它们开始这部分实验之前 , 大约一半的姜黄色老鼠已经发展为黑素瘤,这种现象使研究人员感到震惊。 研究人员首先需要做的就是把一个紫外线光源引入到动物室,而且是万无一失的确保紫外线照射到每一个角落,永不熄灯。结果表明 , 该色素本身就是一种诱发黑素瘤的因素。研究人员提出 , 患黑素瘤风险增加与这种色素的产生过程或生黑色素细胞( melanocytes )形成有关。英国南安普顿大学( University of Southampton )临床皮肤科医生 Eugene Healy 说 , 他虽然对其机理非常感兴趣,但是这种现象与紫外线辐射诱发黑色素瘤相比较,可能是比较少见的。事实上 , 在英国 , 10 例黑色素瘤中就有 8 例是由紫外线照射而引起的。人类大多数皮肤黑素瘤的发展是阳光照射所致。 Eugene Healy 说: “ 你几乎从未在臀部看到黑素瘤 ” 其实就是与阳光照射有关。 Eugene Healy 自己 2010 年发表的研究成果建议保护紫外线辐射对皮肤细胞的另一种类型 —— 角化细胞的影响。太阳安全性信息并不会因为最新的结果而改变。 David Fisher 说: “ 紫外线是非常紧密地与大多数非黑素瘤类的皮肤癌有关联 , 这是无需置疑的。我们研究的最重要的一个信息就是为了避免抛开紫外线就可以万事大吉的假设。紫外线照射有可能会使红色染料加剧致癌机理。 ” Eugene Healy 是希望令人担忧的、肤色白皙的人避免无处不在的各种风险,但我们没有看到在红棕色头发的人群中出现大量自发的黑素瘤。因此,我们不应该发出一个令人担忧的信息。 ” 信息内容请浏览: http://www.nature.com/news/redhead-pigment-boosts-skin-cancer-risk-1.11711

[转载]四成癌症“由病毒引起”
热度 1 xuxiaxx 2011-10-20 08:42
多达四成癌症“由病毒引起”———这一发现有望带来癌症疫苗和新疗法(记者塔玛拉·科恩) 科学家称,可能有多达四成癌症是由病毒引起的,包括脑瘤和白血病。 如果进一步实验的结果证明他们是对的,就将为研制出防治多种癌症的疫苗和疗法铺平道路。 科学家之所以这样说,是因为他们在多种癌症中发现了病毒,而此前人们根本没想到这些癌症与病毒感染有关。 英国每年有30多万人被查出患有癌症,其中有半数会病死。人们早在几十年前就知道某些癌症是由病毒所引起的,但一直认为这一比例只在一两成左右。 可能引发各种癌症的病毒包括:乙肝病毒和丙肝病毒———引发肝癌;人类乳头状瘤病毒———引发宫颈癌;梅克尔细胞多瘤病毒———引发皮肤癌;巨细胞病毒———可能引发儿童脑瘤;爱泼斯坦-巴尔病毒———引发血癌和淋巴癌;XM RV———可能与前列腺癌有关。 其中最广为人知的是可能引发肝癌的乙肝病毒和丙肝病毒以及可能引发宫颈癌的人类乳头状瘤病毒。 瑞典卡罗琳医学院的科学家上周发现了一种与成神经管细胞瘤有关的病毒。成神经管细胞瘤是一种最常见的儿童脑瘤。 科学家在两年前还曾发现,梅克尔细胞癌(一种恶性皮肤癌)的很多患者都感染过多瘤病毒。 多瘤病毒是一种在动物中很常见的病毒,但也可能传染给人类。 还有人提出,前列腺癌也可能是由病毒引起的。 诺贝尔奖得主哈拉尔德·楚尔·豪森说,他认为今后还会有更多的发现证明病毒可能与皮肤癌、乳腺癌、肠癌和肺癌有关。上世纪80年代,楚尔·豪森与其他科学家共同发现了宫颈癌与人类乳头状瘤病毒之间的联系。 不过科学家提醒人们,研制出癌症疫苗可能需要花费漫长的时间和大量的资金。 英国伯明翰大学的癌症学教授艾伦·里金森说:“如果我们能了解这些病毒的运作机理,就可以防止人们被感染,甚至研发出利用患者自身免疫系统摧毁被感染细胞或癌细胞的疗法。” 但病毒致癌的过程仍然令科学家费解,因为病毒会侵入细胞,使它们制造出更多的病毒,不过这个过程会杀死细胞,这意味着它们不可能变成癌细胞。 有一种理论认为,引发癌症的病毒可能在细胞中潜伏多年,以阻止细胞修复变异。 来源: http://news.xinhuanet.com/world/2011-10/19/c_122175093.htm

夏季避光防晒可预防日光性皮肤癌
xupeiyang 2011-6-30 13:28
有足够的证据证明紫外线的照射、人体黑色素的防护与免疫系统功能的相互作用导致了皮肤癌的发生。 在日光中测定人体皮肤,皮肤接受紫外线量最大的部位是头部、面部、颈后、手部,鳞状细胞癌几乎全部发生于这些部位。 如果人在一生中曾多次晒伤,那么这多次和多年晒伤的程度会累加在一起,引起皮肤的损伤,并可引起许多皮肤病,如日光角化病等,因此有皮肤病遗传背景的人更要在夏季避光防晒,因为这种人患日光性皮肤癌的几率要远远超出没有遗传背景的人,如基底细胞癌、鳞性细胞癌、恶性黑色素瘤等。

摄硒能抗癌吗?

摄硒能抗癌吗?
关于硒元素(Selenium,Se)的生物学效应,研究得最多的恐怕是其抗癌作用,但学术界对此历来就存有争议 。 尽管如此,人们还是相信摄硒能够降低癌症风险。许多食物中都富含硒,如巴西坚果(brazil nuts,如下图)。然而,最近的一项随机控制临床试验( RCCT,randomized controlled clinical trials)研 究表明,硒对非黑素类的皮肤癌、前列腺癌都无防范作用。研究结果发表在 Cochrane Database Syst. Rev (2011年,第5期, DOI: 10.1002/14651858.CD005195 )上。主持这项研究的是来自德国柏林THR学院( Institute for Transdisciplinary Health Research )的 Gabriele Dennert 教授。 该研究组搜索了摄硒效应的临床研究文献,发现了49项预期的观察研究( observational studies )和6项随机控制临床试验。其中,观察研究表明,高硒摄入可以防范癌症,但RCCT研究却表明无此明显作用。另外还有迹象表明,如果摄硒时程过长,会造成有害效应。 Russo MW, Murray SC, Wurzelmann JI, Woosley JT, Sandler RS (1997).

皮肤癌遗传研究动态信息分析与知识发现
xupeiyang 2009-10-12 12:57
http://www.reuters.com/article/healthNews/idUSTRE5984VM20091010 Journal of Investigative Dermatology, September 2009 NEW YORK (Reuters Health) - Want to reduce your risk of skin cancer? Wear sun screen, of course. But two new studies suggest that choosing your relatives carefully could also be helpful. One found that having an identical twin with melanoma increased a person's own risk of developing the disease much more than having a fraternal twin with this type of skin cancer. The other found that having a sibling or parent with one of several different types of non-melanoma skin cancer increased risk as well. Several studies have suggested melanoma and other skin cancers run in families, but it can be difficult to tease out the difference between the influence of genes and environment. In the Australian study, Dr. Sri N. Shekar of the University of Queensland in Brisbane and his colleagues attempted to do so by looking at twin pairs in which at least one sibling had been diagnosed with melanoma. They searched through thousands of cases of melanoma reported in Queensland and New South Wales and found 125 twin pairs. In four of the 27 identical twin pairs, both had melanoma, while three of the 98 fraternal twin pairs had both been diagnosed with the deadly skin cancer. Based on these numbers, having an identical twin with melanoma increased a person's own risk of the disease nearly 10-fold, while melanoma associated with having a non-identical twin with the disease was roughly doubled. This suggests, the researchers say, that some of the increased melanoma risk can be attributed to genes, in particular interactions between genes. They estimate that genes account for about half of the differences in risk between two people. In the second study, Dr. Shehnaz K. Hussain of the University of California Los Angeles and colleagues looked at the Swedish Family-Cancer Database to gauge the risk for several types of skin cancer among siblings and children of people diagnosed with these diseases. They found that people with a sibling or parent diagnosed with some types of skin cancer were more likely to develop skin cancers of various types, not just the ones their relatives had. When tumors occurred at parts of the body more likely to have been exposed to the sun (such as the face, compared to the torso), the familial risk was stronger. Based on the findings, Hussain and colleagues conclude, a person's family history can be used to gauge their own skin cancer risk, and genetic studies could be a useful way to identify potential targets for treating or preventing the disease. http://www.sciencenet.cn/htmlnews/2009/10/224008.shtm 皮肤癌新发现:双胞胎风险激增 亲子难逃遗传 想要降低患皮肤癌的风险?除了涂防晒霜保护皮肤外,研究发现,选择自己的父母和兄弟姐妹也对一个人患皮肤癌几率的高低有影响。 美国《皮肤病学研究杂志》( JID )刊登澳大利亚和美国科学家最新研究成果表明,皮肤癌具有遗传性,其发病率与家族基因联系密切。 双胞胎 风险激增 澳大利亚昆士兰大学斯里谢卡尔博士和他的研究小组通过对患有黑色素瘤这种致死性皮肤癌的双胞胎进行研究后发现,同卵双生的双胞胎中如果有一人患有黑色素瘤,那么另一人也患上黑色素瘤的风险将大大增加,甚至高于相同情况的异卵双生双胞胎。 研究小组在昆士兰和新南威尔士两个州调查了数千例黑色素瘤病例,发现其中有125人是双胞胎,包括27例同卵双生和98例异卵双生。 在27例同卵双生双胞胎中,有4对同时患有黑色素瘤;而在98例异卵双生双胞胎中,只有3对同时患有这一疾病。 路透社10月10日援引研究数据报道,如果某人有一个患黑色素瘤的同卵双生兄弟姐妹,那么他本人也患上黑色素瘤的几率约是普通人的10倍;而如果有一个患黑色素瘤的异卵双生兄弟姐妹,那么他本人也患上这种疾病的几率约是普通人的两倍。 亲子间 难逃遗传 由美国加利福尼亚大学洛杉矶分校夏赫纳兹侯赛因博士带领的另一个小组研究了有皮肤癌病史的家族成员患皮肤癌的几率大小。 研究人员通过分析瑞典家庭癌症数据库发现,如果某人的父母或兄弟姐妹患有某种皮肤癌,那么这个人比其他人更有可能患皮肤癌,但不一定是和父母或兄弟姐妹同种类的皮肤癌。 研究人员还发现,当癌细胞出现在容易被太阳照射的部位,如面部时,这种家族遗传性会体现得更明显。 新发现 证实假说 皮肤癌是所有癌症中分布最广泛的种类之一,在任何年龄段都可能发病。 虽然皮肤癌的具体成因至今尚不明确,但可以确定阳光是主要凶手之一。阳光中的紫外线如果长时间照射皮肤,会使皮肤细胞发生变异,引发皮肤癌。 先前有过不少研究指出皮肤癌可能存在某种遗传性关联,但由于它们无法将基因影响和环境影响分开来单独研究,因而始终仅仅是假说而已。 谢卡尔等人的研究第一次用论文的形式证实这种假说的真实性。 研究人员说,他们的研究说明黑色素瘤患病几率的增加可以部分归咎于基因,尤其是基因间的相互影响。他们估计,不同个体之间这种疾病患病风险之所以不同,一半是受基因影响。 更多阅读 美联社相关报道(英文) http://www.gopubmed.org/web/gopubmed/2?WEB017ifjeth1beu6I1aI1I00f01000j10040001rl 1 2 Top Years Publications 2005 12 2007 8 2006 7 2003 7 2008 6 2009 5 2004 5 1998 5 1997 5 1985 5 2002 4 1999 4 1996 4 1995 4 1986 4 2000 3 1989 3 1977 3 1976 3 2001 2 1 2 1 2 Top Countries Publications USA 25 Japan 10 Germany 9 Sweden 7 Italy 7 Spain 3 United Kingdom 3 France 2 Turkey 2 India 2 Australia 2 Israel 2 Iran 1 Pakistan 1 Taiwan 1 United Arab Emirates 1 Poland 1 Brazil 1 Saudi Arabia 1 Netherlands 1 1 2 1 2 3 Top Cities Publications Heidelberg 6 Boston 5 New York 3 Tokyo 3 Barcelona 3 London 3 Rome 2 Bethesda 2 Catania 2 Houston 2 Seattle 2 Kobe 2 Atlanta 1 Uppsala 1 Besanon 1 Tehran 1 Istanbul 1 Charleston 1 Glenview 1 Bangalore 1 1 2 3 1 2 3 4 Top Journals Publications Arch Dermatol 8 J Invest Dermatol 7 J Am Acad Dermatol 7 Int J Cancer 6 Brit J Dermatol 5 Cancer 4 Acta Derm-venereol 4 Pediatr Dermatol 4 J Dermatol 3 Hautarzt 3 Clin Exp Dermatol 3 Am J Dermatopath 3 Ann Dermatol Vener 2 Radiat Res 2 Int J Dermatol 2 Ophthalmology 2 Dermatol Surg 2 Cancer Res 2 Dermatology 2 Cutis 2 1 2 3 4 1 2 3 ... 60 Top Terms Publications Skin Neoplasms 119 Siblings 116 Humans 108 Patients 61 Adult 60 Child 43 Neoplasms 40 Middle Aged 40 Adolescent 36 Carcinoma 34 Diagnosis 27 Parents 27 Syndrome 26 Melanoma 26 Pedigree 24 Incidence 22 Genes 22 autosome 20 Aged 20 Carcinoma, Squamous Cell 20 1 2 3 ... 60 1 2 3 ... 26 Top Authors Publications Hemminki K 4 Geller A 4 Hemminki K 4 Gilchrest B 3 Brooks D 3 Koh H 3 Hussain S 2 Sundquist J 2 Emmons K 2 Powers C 2 Zhang Z 2 Sober A 2 Li F 2 Emmert S 2 Puig S 2 Malvehy J 2 David M 2 Kramer K 2 Khan S 2 Czene K 2 1 2 3 ... 26 http://arrowsmith.psych.uic.edu/cgi-bin/arrowsmith_uic/edit_b.cgi Start A-Literature C-Literature B-list Filter Literature A-query: skin cancer and sibling C-query: Pedigree The B-list contains title words and phrases (terms) that appeared in both the A and the C literature. 35 articles appeared in both literatures and were not included in the process of computing the B-list but can be viewed here .
