　　微博传言大鉴定之三 Micro bo rumors big third identification

　　近期，一则“癌症早已攻克，只需服用大量维生素B17”的惊人消息在网络上广为流传。B17是哪门子维生素？主流医学界研究了几十年都没有攻克的恶性肿瘤竟然被此“神药”轻松搞定？原来，这是一种苦杏仁苷的类似物，其防治癌症的作用没有任何科学依据，一些患者服后反而因为其产生的剧毒氰化物而死亡。

recent,a"Cancer had conquer,Just taking large doses of vitamin B17"The surprising news on the Internet widely circulated.B17 is which son vitamin?The mainstream medicine research for decades are not conquer malignant tumor should be this"God medicine"Easily get?The original,This is a kind of laetrile analogue,The prevention and control of cancer role not based on any scientific evidence,Some patients because of its after service instead of from the highly toxic cyanide and death.

　　微博传闻：神奇“维生素”可对抗癌症 Micro bo rumours:magic"vitamin"Can fight cancer

　　“医生如果得了癌症，他们不会做化疗：维他命B17抗癌。请大量传出去！癌症在几十年前早就有解了，只是真相一直被隐瞒……”

"If the doctor had cancer,They won't do chemotherapy:Vitamin B17 anti-cancer.Please a lot of spread!Cancer in a few years ago would have have a solution,But the truth has been hide..."

　　维他命即维生素，这个传闻连同详细帖子鼓吹大量吃“维生素B17”的防癌、抗癌作用，建议人们吃“带点苦味”的杏仁，例如中药北杏，因为里面含有维生素B17。

Vitamin is vitamin,The rumours together with detailed post preach plenty to eat"Vitamin b17"Of cancer/Anti-cancer effect,Advise people to eat"With a bitter taste"almond,For example, Chinese medicine north apricot,Because it contains vitamin B17.

　　“维生素B17”的化学名称是“L-扁桃腈-β-葡萄糖醛酸”，据说是在上世纪由美国的小恩斯特·克雷布斯合成的苦杏仁苷类似物，而这类物质天然存在于坚果、水果的籽中，例如杏仁核、苹果籽。克雷布斯曾就读于美国哈尼曼医学院，但因学习跟不上而退学，转而在一些资质很差的大学甚至是“野鸡大学”混得学位。克雷布斯为他的“发现”注册了商品名“Laetrile”，称其功能是调节肠道功能，但后来他四处宣传其能预防和治愈癌症。

"Vitamin b17"Chemical name is"L - mandelonitrile - beta glucuronic acid",It is said that is in the United States by the small ernst · Krebs synthetic bitter almond analogues,And this kind of material natural exist in nuts/Fruit seed,For example, the amygdala/Apple seed.Krebs had been studying in the United States ha nyman medical school,But because of learning can't keep up and drop out of school,In some qualifications to poor university even"Pheasant university"Mixed degree.Krebs for his"found"Registered a trade name"Laetrile",Says its function is to control the intestinal function,But then he had to propagate its can prevent and cure cancer.

　　不久，这种物质就被冠上了“维生素B17”的名称，得到众多粉丝追捧，认为是对抗癌症的“自然疗法”。他们认为癌症是缺乏维生素的结果，称维生素B17可有选择性地杀死肿瘤细胞而不伤害正常细胞；后来不敢说治愈了，改说能“控制”癌症，提高患者生活质量；最近又说维生素B17要结合一套“代谢疗法”才有效。

soon,This substance is the crown"Vitamin b17"name,Many fans get chase after hold in both hands,Think is against cancer"Natural therapy".They think that cancer is the result of lack of vitamin,Say vitamin B17 can selectively kill tumor cells and does not damage the normal cells;Then dare not say cured,Change said can"control"cancer,Improve the patients life quality;Recently said vitamin B17 want to combine a"Metabolic therapy"To effective.

　　专家鉴定：维生素B17产生的氰化物可毒死人 Expert evaluation:Vitamin B17 produce cyanide can kill people

　　广州市红十字会医院肿瘤科主任易基群博士指出，这并非真正的B族维生素，科学研究表明，维生素B17在人体内被酶分解之后会产生有毒的氢氰酸，令一些患者服后出现恶心呕吐、头晕目眩的症状，也有大量进食此类食物氰化物中毒的报道。

Guangzhou Red Cross hospital oncology department director dr us group pointed out,This is not the real B vitamins,A scientific research shows that,Vitamin B17 by enzymes in the body after decomposition can produce toxic hydrocyanic acid,Make some patients take nausea vomiting/Dizzy symptoms,Also have a large number of eating this kind of food cyanide poisoning reports.

　　美国国家癌症研究所调查了大量声称服用维生素B17获得疗效的患者，结论是“没有确切结论支持其有抗癌活性”。

The us national cancer institute survey of claimed that taking vitamins B17 obtain curative effect of the patients,Conclusion is"No definite conclusion support its antitumor activity".

　　全美反卫生欺诈委员会副会长、医学博士史蒂芬·巴雷特介绍，科学家在癌症患者和20多种动物身上进行维生素B17实验，未发现它有任何疗效。

The reverse health fraud committee vice chairman/Medical doctor Stephen Barrett is introduced,Scientists in cancer patients and 20 a variety of animals has vitamin B17 experiment,Did not find it have any effect.

　　美国梅奥诊所等权威医疗机构组织了178名患者进行临床试验，发现维生素B17及代谢疗法没治愈或缓解一例，反而有很多人治了几个月后死亡。

The Mayo clinic with other authoritative medical institutions organized 178 patients in clinical trials,Found that vitamin B17 and metabolic therapy didn't cure or alleviate case,But there are a lot of man died after several months.

　　易基群提醒，目前未有维生素B17能防癌、抗癌的足够依据，进食大量含苦杏仁苷类的食物(如北杏)既不安全，也不能起到抗癌作用。

Group remind us,Currently there is vitamin B17 can prevent cancer/Anticancer enough basis,Eating a lot of including laetrile class food(Such as north apricot)Neither safety,Also cannot have anti-cancer effect.

　　专家提醒：伪科学疗法反而声称受到“压制” The expert reminds:Pseudoscience therapy but claimed by"pressing"

　　在癌症治疗领域出尽洋相之后，“维生素B17”的粉丝们转而声称它能治疗艾滋病、关节炎、心血管病等。美国外科医生本杰明·威尔逊博士称，只要存在致残、致命的疾病，总有人在科学的疗法之外提供“替代”的疗法，也总会有大量绝望的患者愿意购买。

In the field of cancer therapy after all the spectacle,"Vitamin b17"Fans to says it can cure AIDS/arthritis/Cardiovascular disease.The United States surgeon Benjamin dr Wilson says,As long as there is a disability/Fatal disease,Someone in the scientific therapy provide outside"alternative"therapy,There will always be a large number of despair of patients are willing to buy.

　　巴雷特介绍，各种不靠谱的癌症治疗方法常常宣传很多患者接受治疗后“有效”，却没有说有多少人治疗后无效。所谓“治愈”的案例无非是这几种情况：要么患者得的不是癌症，要么癌症根本没有治好，要么癌症被正规的疗法治好了，却归功于同时进行的“疗法”。

Barrett is introduced,All kinds of cancer treatment without spectrum method often propaganda many patients after treatment"effective",But did not say how many people after treatment is invalid.The so-called"cure"Case is nothing but this several ways:Or the patients not cancer,Either cancer no cure,Either cancer be formal therapy healed,But at the same time to"therapy".

　　有些不靠谱的伪科学疗法常常宣称，医院、药厂、政府机构等为了自身利益而反对他们，压制治愈癌症的“新发现”，例如“维生素B17”的粉丝认为对这种药的反对是邪恶的阴谋，“癌症在几十年前早就有解了，只是真相一直被隐瞒”就是典型的论调。巴雷特称这属于阴谋论，很多癌症患者在接受正规治疗无效的情况下感到绝望就特别容易相信。　　文/记者伍君仪 通讯员胡颖仪
