艾滋病癌症英语论文

Acquired immunodeficiency syndrome (AIDS) is an AIDS virus,that the human immunodeficiency virus (human HIV) dormant in the human body and the human immune function and occurrence of a variety of human tumors and incurable infection,finally led to the deaths of a serious infection is the generic AIDS medicine, "acquired immune deficiency syndrome," Acquired Immune Deficiency Syndrome first word of the name of the concept of AIDS, AIDS, we can learn from the three clearly defined :Acquired : etiology is acquired at birth rather than have the : defects in the immune damage was mainly caused by the body's immune system and cause the immune system to reduce the protective function deficiency is a common feature : a.. B. increased susceptibility to infection. Prone to cancer;c. The clinical and pathological features : at the clinical symptoms, as a result of defects in various immune system against opportunistic infections,Tumors arising from the complex is a retrovirus infection caused by the body's immune defense system a normal human body, the immune system plays a good body of the "defensive",various pathogens to resist the one HIV-infected, a good body defense system will be destroyed, defense microbial pathogens and thus able to drive straight into the opportunity Hematogenous wounds and addition, the number of abnormal body cells, such as cancer cells, also flew rapid growth, large population,develop into all types of other words, the immune system of AIDS patients is mainly expressed serious injury, the body resistance decreasedSome serious infections and even induced a rare carcinoid originated in Africa, young people are also in Haiti in 1979 and distributed by the immigrants into the United 5, 1981, the United States Centers for Disease Control in in the "Morbidity and Mortality Weekly," a brief introduction to the five cases they found that the history of AIDS will be officially named the disease "AIDS."Soon after, the rapid spread of AIDS in the June 1985, in Shanghai by a young American male tourists from Argentina AIDS patient cured in the country, this is the first case of AIDS in has been in China since 1985 and nearly 10,000 people enter the AIDS virus to speculation in the next few years : AIDS trend is downward trend in the developed countries is,while for developing countries was a sharp upward as "contemporary plague" and "super cancer" AIDS has caused the World Health Organization (WHO) and national governments attach great importance to it,The inputs of both staff and financial resources to be top priority, China has been included in Category B surveillance of infectious diseases and one territory.翻译：艾滋病（AIDS）是一种由艾滋病病毒，即人体免疫缺陷病毒（human immunodeficiencyvirus，简称HIV）侵入人体后破坏人体免疫功能，使人体发生多种不可治愈的感染和肿瘤，最后导致被感染者死亡的一种严重传染病。AIDS是艾滋病的医学全称“获得性免疫缺陷综合症”Acquired Immune Deficiency Syndrome的英文字头缩写词。这个命名表达了艾滋病的完整概念，从中我们可以了解到艾滋病的三个明确定义：获得性：表示在病因方面是后天获得而不是先天具有的。 免疫缺陷：表示在发病机理方面，主要是造成人体免疫系统的损伤而导致免疫系统的防护功能减低、丧失。 免疫缺陷病的共同特点是：a.对感染的易感性明显增加；b.易发生恶性肿瘤；c.临床及病理表现多样化。 综合症：表示在临床症状方面，由于免疫缺陷导致的各个系统的机会性感染、肿瘤而出现的复杂症状群。 艾滋病是一种由逆转录病毒引起的人体免疫防御系统方面的疫病。人体处于正常状态时，体内免疫系统对机体起着良好的“防御”作用，抵抗各种病原体的袭击。一但受艾滋病病毒感染之后，人体的这种良好防御系统便会受到破坏，防御功能减退，因而这时病原体及微生物得以乘机经血行及破损伤口长驱直入。此外，身体中一些不正常的细胞，例如癌细胞，也同样乘机迅速生长、大量繁殖起来，发展成各类癌瘤。也就是说，艾滋病病人主要表现为免疫系统受到严重损伤，机体抵抗力下降，以至诱发严重感染和一些少见的癌瘤。 艾滋病发源于非洲，1979年在海地青年中也有散发，后由移民带入美国。1981年6月5日，美国亚特兰大市疾病控制中心，首次在《发病率与死亡率周刊》上简要的介绍了他们发现的五例艾滋病病人的病史。1982年正式将此病命名为“艾滋病”。以后不久，艾滋病迅速蔓延到了各大洲。1985年6月，由上海入境的一名美籍阿根廷青年男性游客因艾滋病住院，治愈无效，死于我国境内，这是出现在我国的首例艾滋病。艾滋病自1985年进入我国至今已有近万人为艾滋病病毒携带者。据有关部门推测，在今后几年内艾滋病发展趋势是：发达中国家是呈下降趋势，而发展中国家则呈急剧上升趋势。 被称为“当代瘟疫”和“超级癌症”的艾滋病已引起世界卫生组织（WHO）及各国政府的高度重视，无论是人员和经费的投入均放在首位，我国已将其列入乙类法定传染病，并为国境卫生监测传染病之一。
