Soy food good for womenWomen who ate soy regularly as children have a lower risk of breast cancer, American researchers report. And men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the American Association for Cancer Research. The studies add to a growing body of evidence about the role of diet in cancer. Cancer experts now believe that up to two-thirds of all cancers come from lifestyle factors such as smoking, diet and lack of exercise. The US National Cancer Institute and researchers at the University of Hawaii found that women who ate the most soy-based foods, such as tofu and miso, when aged 5 to 11, reduced their risk of developing breast cancer by 58 per cent. It was not clear how soy might prevent cancer, though compounds in soy called isoflavones have estrogen-like effects. A second study showed that men who ate fish at least five times a week had a 40 per cent lower risk of developing colorectal cancer compared with men who ate fish less than once a week. Many kinds of fish are rich in omega-3 fatty acids, which interfere with the cyclooxygenase-2 or COX-2 enzyme. COX-2 affects inflammation, which may play a role in tumour growth.据美国研究人员报告，儿童时期经常吃豆类食品的女性患乳腺癌的风险较小。
另一组研究人员则向美国癌症研究协会提出，一周吃几次鱼的男性患结肠癌的几率较小。
这两项研究进一步证明了饮食对于防癌的作用。
癌症防治专家认为，在所有种类的癌症中，多达三分之二都是由吸烟、节食及缺乏锻炼等不健康的生活方式造成的。
美国全国癌症研究所和夏威夷大学的研究人员发现，在5岁至11岁时经常吃豆腐、味噌等豆类食品的女性患乳腺癌的几率要低58%。
至于豆类食品为什么可以防癌还不清楚，不过大豆中所含的名叫异黄酮的化合物具有雌性激素的作用。
另一项研究表明，一周吃鱼至少五次的男性患结肠癌的风险要比那些一周都吃不到一次鱼的男性低40%。
很多鱼类中所富含的Omega-3脂肪酸能够抑制环氧化酶2的活性。
环氧化酶2会引起发炎，这可能会刺激肿瘤的生长。
If you're middle-aged and your memory's not what it used to be, check the bathroom scale, researchers warned, suggesting overweight people tend to score more poorly on tests of memory than their thinner peers do. The findings suggest that a heavier weight in middle age may mean a higher risk of dementia later in life. Reporting in the journal Neurology, the researchers speculated that higher rates of cardiovascular disease or diabetes might help explain the link. But it's also possible that substances produced by fat cells, such as the hormone leptin, have direct effects on the brain. The study compared mental abilities to body mass index (BMI), a measurement of weight in relation to height used to define overweight and obesity. A BMI of 25 or more indicates overweight, and 30 or more is obese. The study also investigated the relationships between BMI and cognitive function in 2,223 healthy men and women between the ages of 32 and 62 in France through the use of four cognitive tests. The study found a higher BMI was associated with lower cognitive test scores. Results from a test involving word memory recall show people with a BMI of 20 remembered an average of nine out of 16 words, while people with a BMI of 30 remembered an average of seven out of 16 words. 研究人员提醒，如果你已步入中年，发现自己的记忆力不如从前，那么你得小心体重了。
研究表明，超重的人记忆测试的得分要比较瘦的人低。
研究发现，体重偏大的中年人今后患老年痴呆症的可能性较大。
研究报告在《神经学》期刊上发表，研究人员推断，心血管疾病及糖尿病的高发现象可以解释其中的原因。
此外，脂肪细胞所产生的物质，如瘦体激素，对大脑有直接影响。
此项研究将调查对象的智力与体重指数进行了对比。
体重指数指的是身高和体重之间的比例，主要用来衡量一个人是否偏胖或肥胖。
体重指数为25或25以上的人偏胖，达到30或30以上的人则为肥胖。
研究人员还对体重指数和认知功能间的关系进行了研究，他们在法国对2223位年龄在32岁至62岁间的健康男女进行了认知测试。
研究发现，体重指数越大，认知测试的得分越低。
其中一项单词记忆的测试结果表明，在16个单词中，体重指数为20的人平均能记住9个，而体重指数为30的人平均只能记住7个。
People who do not get enough sleep are more than twice as likely to die of heart disease, according to a large British study released Monday.Although the reasons are unclear, researchers said lack of sleep appeared to be linked to increased blood pressure, which is known to raise the risk of heart attacks and stroke.A 17-year analysis of 10,000 government workers showed those who cut their sleep from seven hours a night to five or less faced a 1.7-fold increased risk of death from all causes and more than double the risk of cardiovascular death.The findings highlight a danger in busy modern lifestyles, Francesco Cappuccio, professor of cardiovascular medicine at the University of Warwick's medical school, told the annual conference of the British Sleep Society in Cambridge.A third of the population of the UK and over 40 percent in the US regularly sleep less than five hours a night, so it is not a trivial problem, he told reporters.Previous research has highlighted the potential health risks of shift work and disrupted sleep. But the study by Cappuccio and colleagues, which was supported by British government and US funding, is the first to link duration of sleep and mortality rates.The study looked at sleep patterns of participants aged 35-55 at two points in their lives - 1985-88 and 1992-93 - and then tracked their mortality rates until 2004.The results were adjusted to take account of other possible risk factors such as initial age, sex, smoking and alcohol consumption, body mass index, blood pressure and cholesterol.Cappuccio said it was possible that longer sleeping could be related to other health problems such as depression or cancer-related fatigue.In terms of prevention, our findings indicate that consistently sleeping around seven hours per night is optimal for health, he said.(Agencies) 本周一公布的一项大规模英国调查表明，睡眠不足的人死于心脏病的几率是睡眠充足者的两倍多。
目前其中的原因尚不清楚，但研究人员称，睡眠不足会导致血压升高，从而增大患心脏病和中风的风险。
一项针对1万名政府职员、长达17年的跟踪调查表明，每晚睡眠时间从七个小时减少到五个小时或更少的人因各种原因而死亡的几率是睡眠正常者的1.7倍，而且死于心血管疾病的风险也增加了1倍多。
沃里克大学医学院的心血管药物学教授弗朗西斯哥•卡普西奥在英国睡眠学会在剑桥召开的一年一度的研讨会上说，这一研究成果揭示了忙碌的现代生活中潜在的危险。
他在接受记者采访时说：“三分之一的英国人以及超过40%的美国人每晚的睡眠时间常常达不到五个小时，所以这个问题不可小视。
”此前有调查发现轮班及睡眠中断会对健康产生潜在威胁。
但卡普西奥及其同事的这项调查则首次揭示了睡眠时间长短与死亡率之间的关系。
该调查由英国政府和美国基金提供资助。
该调查对年龄在35岁至55岁之间的人在1985年至1988年以及1992年至1993年两个阶段的睡眠模式进行了探究，并对这一人群截至2004年的死亡率进行了追踪。
调查还考虑到了调查对象的初始年龄、性别、是否吸烟喝酒、体重指数、血压及胆固醇指标等其它可能的风险因素。
卡普西奥说，睡眠时间过长也可能导致如抑郁症及癌因性疲乏等其它健康问题。
他说：“就预防而言，我们的研究结果表明，每晚睡眠时间持续保持在七小时左右最益于身体健康。

What is depression?什么是抑郁症
Depression is a mood disorder that causes you to feel sad or hopeless for an extended period of time. More than just a bout of the blues or temporary feelings of grief or low energy, depression can have a significant impact on your enjoyment of life, your work, your health, and the people you care about. 抑郁是在一段时间内持续的一种精神絮乱，它让人感觉悲伤，对生活失去希望。
不止发作一次的悲伤心情，或没有精力，抑郁对人们的生活，工作，健康，甚至对周围的人们都会产生很大的影响。
Depression affects people differently. Some feel down for extended periods of time; for others the feelings of depression come and go. If you have short episodes of mild depression, you may be able to continue to work and take care of daily activities. However, if you do not seek some form of treatment for your depression, you are at risk for getting more depressed or becoming physically ill. In severe cases, depression can cause people to become incapable of communicating, unable to do routine activities, or suicidal. In these cases, it is essential to seek medical attention. 抑郁对人们的影响是不同的。
有些人经常情绪失落，而有些人只是偶尔有这种情绪。
如果你偶尔有这轻微的抑郁，可能你能继续工作，应付日常工作。
但，如果不对你的抑郁寻求一些治疗，你可能就会变得更加抑郁，或生病的风险。
严重抑郁会导致人无法正常交流，不能进行日常的活动，甚至自杀。
在这种情况下，寻求药物治疗就非常重要。
People with depression may be reluctant to seek help because they feel that it is a sign of personal weakness or a character flaw or that they should be able to pull out of it on their own. We now know that depression, like other medical conditions, has a chemical and biological basis. Treatment for depression is safe and usually effective even for severely depressed people. 患抑郁的人通常认为它是个人性格上的弱点，或是性格上的缺陷，他们认为能够通过自身的努力消除，从而他们不愿意寻求帮助。
我们知道，抑郁和其它的疾病一样，都有生物和化学基础。
治疗是安全的，对于患有严重抑郁的人，它通常是非常有效的。
If you think you may have depression, take a short quiz to evaluate your symptoms: 如果你认为你可能有抑郁的话，填写一份简短的测试问卷来分析你的症状。
Are you depressed?你抑郁吗
What causes depression?什么会引起抑郁
Depression may be triggered by stressful life events, other illnesses, certain drugs or medications, or inherited traits. Although causes of depression are not entirely understood, we know it is linked to an imbalance in brain chemistry. Once the imbalance is corrected, symptoms of depression generally improve. 过高压力的生活事件，其它疾病，一些药物或治疗，或遗传因素等都有有可能引发抑郁。
虽然抑郁的起因不能完全搞清楚，但我们知道它和大脑内某种化学物质的失衡有联系。
一旦这种失衡被纠正之后，抑郁就会大大的改善。
What are the symptoms?抑郁有哪些症状
Depression is more than just the normal, temporary feelings of sadness and hopelessness associated with difficult life events. Common symptoms include: 抑郁是一种和困难生活事件相关的，自然的，临时性的，伤心，失望的一种感受。
一般的症状包括：Depressed mood.情绪抑郁。
Inability to enjoy activities.不能享受运动。
Problems concentrating.注意力无法集中。
Poor memory.记忆力差。
Difficulty making decisions.优柔寡断 Changes in eating habits.饮食习惯改变。
Weight gain or weight loss.体重增加或减少。
Changes in sleeping habits.睡眠习惯改变。
Difficulty going to work or taking care of your daily responsibilities.无法正常地进行日常工作和生活。
Feelings of guilt and hopelessness; wondering if life is worth living (common).有罪恶感，感觉没有希望；怀疑生命存在的价值（普遍现象） Slowed thoughts and speech.思考缓慢，表达缓慢。
Preoccupation with thoughts of death or suicide.常常想到死亡，或自杀。
Complaints that have no physical cause (somatic complaints) such as headache and stomachache.抱怨不存在的身体病痛，例如，头痛，胃痛。
All of these symptoms can interfere with your quality of life. Even if you don't have major depression, if you have experienced a few of these symptoms for at least 2 weeks you may have a less severe form of depression that still requires treatment. 所有的这些病症都会影响生活质量。
即使没有这些主要的症状，如有这其中这些部分现象持续超过二周时间的，可能就患有轻度的抑郁，仍然需要治疗。
How is it treated?如何治疗
Depression is usually treated successfully with professional counseling or antidepressant medication. Often a combination of the two is most effective. People with depression usually can be treated as outpatients, but in severe cases a period of hospitalization may be necessary. 通过专业的开导或服用抗抑郁药物，都可能成功的治疗抑郁。
通常将二者结合治疗效果更佳。
通常抑郁患者不需住院治疗，但情况严重的，需要住院一段时间。
If you have mild or moderate depression, you may be diagnosed and treated by your family health professional and a therapist or psychologist. If you have severe depression or other psychological disorders or do not respond to treatment, a psychiatrist, a doctor who specializes in the diagnosis and treatment of mental health problems, may be helpful. 如果患有轻微或中度的抑郁，可以通进家庭医生或临床医师或心理专家进行诊断和治疗。
严重的抑郁，或其它的精神絮乱，或治疗无效的，精神健康专业医生可能会提供帮助。
Let your health professional know if you suspect that you have depression, because it is often overlooked. If you are diagnosed with depression, you and your health professional can decide on the best treatment. The earlier you are treated, the more quickly you will recover. 如果你怀疑自已有抑郁，一定要让你的健康医生知道，因为它通常会被忽略。
如果你被诊断患有抑郁，一起和你的健康医生决定最好治疗方案。
越早治疗，越早恢复。
How common is depression?抑郁普遍吗
If you have symptoms of depression, you are not alone. In the United States, an estimated 15% of people will have depression at some point in life, and chances of becoming depressed are even higher for certain people. For example: 如果你有抑郁的症状的话，你并不孤单。
在美国，预计15%的人都有抑郁，某些有患抑郁的有可能性还要高些。
例如： Women experience depression twice as often as men, although men are more likely to commit suicide as a result of depression.女性患抑郁的可能性是男性的两倍，虽然，男性在患抑郁之后比女性更易自杀。
Separated or divorced individuals, especially men, are more likely than married people to become depressed. 分手或离异的人，特别是男性，比结婚的人更易患抑郁。
People who have a serious illness are more likely to suffer from depression. 患有严重疾病的人更易患抑郁。

养生的演讲稿
尊敬的各位领导，各位同仁，大家下午好
当季节走进粉红色的五月，当枝头变成郁郁葱葱的绿洲，我们迎来了自己的节日--国际护士节。
今天我演讲的题目是《假如我是一名患者》.中国有句成语：叫做“设身处地”，它的意思就是换位思考。
假如我是一名患者这个命题，就是提倡换位思考。
有这样一个地方，它包含着人生万象，生老病死，欣喜悲伤，一声蹄哭，一个个新生命在这里闪亮登场，我们很欣慰，我们的工作是迎接新生命的到来，这就是医院，我把它比作人生大舞台。
从拿到执业护士证那天起，我就在这个大舞台上演绎着青春旋律。
在重复的工作中我感受到了医务工作者的价值所在，也体会到了被病患折磨的痛苦。
假如我是一名患者，我希望一走进医院就有种温馨的感觉，处处散发着阳光的味道，医护人员就像我的亲人一样，能给我关怀与温暖，鼓励我战胜病魔。
假如我是一名患者，我想我需要的不仅仅是精湛的技术和满意的疗效，我更需要的是一种“人性化”的服务。
假如我是一命患者，我渴望迎接我的医生，护士带着真诚的微笑，像久违的朋友带给我坚强和自信，唤起我对生命的向往。
假如我是一名患者，也许我会变得敏感多疑，焦躁不安，蛮不讲理，请你们千万不要介意，请你们理解我的心情，敏感与不安是源于我对疾病的恐惧和对医学知识的缺乏，焦躁与蛮横是因为我多么渴望健康，多么想与所有人一样享受生命。
其实只有站在患者的立场换位思考，我们才能了解到我们的不是，才能更好的为患者服务，我们谁也免不
