PARIS — France's government on Wednesday asked a health watchdog to carry

据英国《每日邮报》1月7日报道,英国科学家找到了“急性癌症”的形成原因:细胞内
的染色体发
生“爆炸”破坏了DNA,从而让人有可能在短时间内患上癌症。相关论文发表于《细胞
》。
传统理论认为癌症是人体经历成千上万次的细胞突变后,慢慢演化的结果。但英国著名
的疾病研究机
构桑格研究所的新发现推翻了这种看法。这暗示了不管人们怎么努力保持身体健康,也
不能保证命运
不会拿他们开玩笑。同时还说明了为什么有些人在体检时根本没发现癌症痕迹,但数月
后突然就被诊
断患上这种疾病了。
桑格学院的科学家是通过研究750个肿瘤的遗传缺陷后得出以上结论的。其中大部分的
案例都与传统
理论相符,染色体的损坏是常年累积的结果。然而,其中至少有1/40的肿瘤不符合“标
准模式”,有的
染色体似乎是在一夜之间遭到破坏的。
参与此项研究的坎贝尔博士称:“测验结果太让我们惊讶了。在一个细胞里面,染色体
经过一次或者是
多次爆炸成为碎片。如果这个细胞开始笨拙地修补,把碎片杂乱的缝合起来,这样就破

1. 这个mutational load theory本身就很有瑕疵,如果看看几篇N Eng J Med的文章,

The elucidation of breast cancer subgroups and their molecular drivers
requires integrated views of the genome and transcriptome from
representative numbers of patients. We present an integrated analysis of

那流多少呢?一丁磕了碰了最多一次把衣服前胸弄湿了一块,平时就是几滴的样子。这
两天早上一起床都床上都是一片,实在有点儿害怕。
医生,哎,我也挺生气的,可是就是这个制度。她还算最有经验的一个,本来我一早就
带着一丁去clinic了,特意没吃饭,后来看上午都是年轻的几个医生,就约了下午五点
的又去了一趟,等到5:30,医生就看了一下鼻子说没事儿,我把前后情况说了一下,
就被数落了。。。我可能是有点儿唠叨担心,以前我手指骨头有了tumour,也是去看两
三次看不出来,他们老说就是骨折了自己会好的,后来回了国照了x光才发现是tumour
,做了手术才好了。所以我不太相信他们的水平,每次都自己查半天,可能说的也多些
。尤其看到这个血液病,主要就是白血病,很担心。网上没说频繁流鼻血就一定是,但
是建议验血排除一下。

也说汉语的“词汇量”
长期以来,汉语不但以难学著称,而且还常常被指责为词汇欠缺、表达贫乏。生为汉人
,真可谓双倍之不幸——语言学习所需的时间本来就已经比别人多了好几倍,不料最终
学到的东西还不及人家几分之一。
毛喻原先生便为这种论点提供了具体数据:“我们知道,汉语一部普通的《新华字典》
所收单字(含繁体、异体)是一万一千一百个左右,清初所编的《康熙字典》所收汉字
是四万七千多个,最近出的《汉语大字典》所收汉字也才五万六千个。与英语相比,汉
语的词汇量是非常小的。即使一部欧美普通学生所用的字典所收单词也至少在十六至十
七万个以上。如著名的《牛津字典》所收单词是六十多万个。篇幅最大的《韦伯斯特大
词典》所收单词几乎达到一百万之多。仅从词汇量来比较,汉语和英语在这方面的差别
是非常巨大的。”
显然,毛先生“汉语词汇量非常小”这一结论,是用“科学方法”计算出来的,即:拿
英语单词总量减去汉字字数总量。显然,这么简单的题目,连小学生都难不倒,根本用
不着毛先生亲自动手。不过,小学生同时还知道,加减法的运算有一个先决条件,即“
单位”必须相等。例如,五匹马与四头牛就不好相加;七颗白菜减三根萝卜也不... 阅读全帖

Terminally ill Chinese Nobel peace laureate Liu Xiaobo has asked to be
allowed to go abroad for liver cancer treatment, his friends say.
His wife has formally requested to leave China but it is not clear if the
authorities will approve it, they add.
Mr Liu, 61, has been in hospital after gaining medical parole.
He was jailed in 2009 for "inciting subversion" after calling for multi-
party democracy and respect for human rights in China.

来自主题: Military版 - Breast cancer 'linked to bra size'
大奶子有惊喜
Women with larger breasts are more likely to develop breast cancer, scientis
ts believe
A study of more than 16,000 women found those with a larger bra size were at
greater risk of the disease.
The link could be down to the sex hormone oestrogen that can trigger the gro
wth of mammary glands and tumours.
The researchers found seven genetic factors significantly associated with br
east size - three of which are strongly correlated with mutations already li

The participants then rated their health, noting any long-standing
conditions.
Results revealed the women who had 10 or more lifetime sexual partners were
91% more likely to be diagnosed with any form of cancer than those who were
virgins or had slept with just one person.

我看了下文章的表格1, 上面的数据表明, 离高压线近, 虽然Leukaemia病例上升了, 但
CNS/brain tumours & Other diagnoses 病例却减少了. 以一个病种上生换来了很多
病例下降, 好象有预防作用.
个人觉得该文可信度不高.
