根据国际癌症研究中心(ICRC)估计,未来全球癌症发病人数每年将以3%~5%的速度递增,预计2020年将有2000万新发病例,死亡病例将达1200万。我国是癌症高发地区,肿瘤发病人数占世界1/4,每年有160万~200万癌症患者死亡。目前城市中癌症已占居民死亡总数的25%,农村为21%,严重威胁人民的健康和生命。于是人们寄希望于肿瘤 相似文献

癌症是当代人类三大原因之一。在疾病谱中也占有重要的地位。据统计,目前全世界约有千余万人患有癌症,全年新发病例达一千余万人,数百万人死于非命。美国1974年的资料,每年死于癌症者就有36万人;日本1983年的资料,每年死于癌症者也有17.6万人。因此,癌症是种威胁人类健康和生命的严重疾病,已在世界医学领域中引起广泛重视。 相似文献

目的了解江门市区居民恶性肿瘤的死亡状况及变化趋势,为制定恶性肿瘤防治规划提供依据。方法对2006-2008年江门市区居民恶性肿瘤死亡资料进行统计分析,计算死亡率、死因顺位、构成比等指标。结果 2006-2008年江门市区居民恶性肿瘤死亡2277人,死亡率为124.01/10万,其中男性恶性肿瘤死亡1516人,死亡率为163.84/10万,女性恶性肿瘤死亡761人,死亡率为83.54/10万,男性恶性肿瘤死亡率明显高于女性。3年间恶性肿瘤死亡率呈年度上升趋势,其中女性的上升趋势更明显。恶性肿瘤死因顺位前十位的依次为肺癌、肝癌、大肠癌、胃癌、食管癌、鼻咽癌、白血病、乳腺癌、胰腺癌、脑癌。男性肺癌、肝癌、食管癌、鼻咽癌死亡率明显高于女性。恶性肿瘤死亡率随年龄增加而上升。结论恶性肿瘤是近年江门市区居民的主要死因之一,位居全死因首位,须加强肺癌和消化系肿瘤的防治力度,同时应重视女性乳腺癌的防治。今后本市肿瘤防治的重点是加强健康教育,开展主要恶性肿瘤的筛查和社区癌症康复工作。 相似文献

心理社会因素与女性恶性肿瘤 总被引:3,自引:1,他引:2
近半个世纪以来 ,随着生活模式和生存环境的改变 ,某些女性恶性肿瘤的发病率呈逐年上升趋势 ,与 1 975年相比 ,1 990年女性癌症新病例数增加了近 90万例 ,逐渐成为严重威胁妇女生命与健康的重要疾病。恶性肿瘤的致病因素是多方面的 ,除生物学方面的因素 ,心理社会对女性恶性肿瘤的影响越来越受到人们的广泛重视。1 女性恶性肿瘤的范围全身各系统器官的恶性肿瘤在女性都可见到。常见的女性恶性肿瘤包括两大类 :一是特发于女性的恶性肿瘤 ,如子宫癌、卵巢癌、宫颈癌、阴道癌、外阴癌和女性乳腺癌 ;二是两性均可发生的恶性肿瘤 ,如肺癌和结、… 相似文献

全世界估计约有癌症患者数千万,每年约有600万因癌症而死亡,且每年又新增700万患者。其中,我国每年新增180万,发生率城市约为10万分之70(70/10万),患癌症而死亡的人数135.59/10万,成为人类健康第一杀手。更为严重的是癌症转移复发率高,治愈率低,死亡率高达80%,这些数字令人震惊,难怪人们“谈癌色变”。 相似文献

A further analysis of already published data supports the position that retardates of low ability level less frequently have retarded siblings, retarded parents, and parents low in occupational level than do retardates higher in ability level. The analysis supports the position that there are two types of retarded individuals, persons retarded as a result of gene or chromosomal anomalies, brain injury, etc., who more frequently occur in the lower-level retardate group, and persons whose retardation represents polygenic segregation, who more frequently occur in the higher-level group. 相似文献

Eighteen families in which both parents had refractions within the range of +4·0 D to −4·0 D and axial lengths seen in emmetropia (22·3-26·0 mm) showed coefficients of correlation of the order 0·5 indicative of polygenic inheritance. Such coefficients were seen for axial length (0·407) and for the cornea (0·487), but not for the lens (which is known to be yoked to the axial length). No such coefficients were seen in 19 families in which one of the parents had axial length outside the emmetropic range (nine families with long axes and 10 with short axes).
The pattern of polygenic inheritance for emmetropia (completely correlated optical components) and errors of refraction up to 4·0 D (inadequately correlated components: correlation ametropia) follows that seen in stature and other measurable characters. In contrast the high refractive errors with their abnormal axial lengths (component ametropia) are—like the extremes in stature—pathological anomalies with monofactorial inheritance.

Editorial note. This article is published as part of a discussion. Particular issues of the article are disputable. First
of all, this concerns the so-called “folder” method of introduction of international standards for medical devices to domestic
medical practice (i.e., by direct translation of the standards and their publication as standardizing documents). Nevertheless,
at least one of the problems, the problem of coordination between domestic state standards for medical devices and international
recommendations of ISO and IEC, is undoubtedly of topical importance. Advancement of new health service legislation which
is to be approved by law-makers will definitely introduce corrections into the present situation. The Editorial Board of Meditsinskaya
Tekhnika believes this article will lessen these problems and to be welcomed by readers. 相似文献
