Want to Know Your Disease Risk? Check Your ExposomeA)When it comes to health, which is more important, nature or nurture? You may well think your genes are a more important predictor of health and ill health. Not so fast. In fact, it transpires(得知)that our everyday environment outweighs our genetics, when it comes to measuring our risk of disease. The genome(染色体组，基因组)is out—welcome the exposome(环境暴露).B)"The exposome represents everything a person is exposed to in the environment, that's not in the genes, "says Stephen Rappaport, environmental health scientist at the University of California, Berkeley. That includes stress, diet, lifestyle choices, recreational and medicinal drug use and infections, to name a few. "The big difference is that the exposome changes throughout life as our bodies, diets and lifestyles change, "he says. While our understanding of the human genome has been growing at an exponential(迅速发展的)rate over the last decade, it is not as helpful as we hoped in predicting diseases. "Genes only contribute 10 percent to the overall disease burden," says Rappaport. "Knowing genetic risk factors can prove absolutely futile(无用的)," says Jeremy Nicholson at Imperial College London. He points to work by Nina Paynter at the Brigham and Women's Hospital in Boston, who investigated the effects of 101 genetic markers implicated in heart disease. After following over 19,000 women for 12 years, she found these markers were not able to predict anything about the incidence of heart disease in this group.C)On the other hand, the impact of environmental influences is still largely a mystery. "There's an imbalance between our ability to investigate the genome and the environment," says Chris Wild, director of the International Agency for Research on Cancer, who came up with the idea of the exposome. In reality, most diseases are probably caused by a combination of the two, which is where the exposome comes in. "The idea is to have a comprehensive analysis of a person' s full exposure history," says Wild. He hopes a better understanding of exposures will shed a brighter light on disease risk factors.D)There are likely to be critical periods of exposure in development. For example, the time from birth to 3 years of age is thought to be particularly important. "We know that this is the time when brain connections are made, and that if you are obese(过度肥胖的)by this age, you'll have problems as an adult," says Nicholson. In theory, a blood or urine sample taken from an individual could provide a snapshot of what that person has been exposed to. But how do you work out what fingerprints chemicals might leave in the body? The task is not as formidable(艰难的)as it sounds. For a start, researchers could make use of swatches(样本)of bio-bank information that has already been collected. "There has been a huge international funding effort in adult cohorts(一群)like the UK Bio-bank already," says Wild. "If we improved analysis, we could apply it to these groups."E)Several teams are also working towards developing wearable devices to measure personal exposure to chemicals in the environment. "We can put chemicals in categories," says Rappaport. "We could start by prioritizing toxic chemicals, and look for markers of these toxins in the blood, while hormones and metals can be measured directly." Rappaport is looking at albumin(白蛋白),a common protein in the blood that transports toxins to the liver where they are processed and broken down. He wants to know how it reacts with a range of chemicals, and is measuring the products. "You can get a fingerprint—a display of all the products an individual has been exposed to."F)By combining this information with an enhanced understanding of how exposure affects health, the exposome could help better predict a person's true disease risk. And we shouldn't have to wait long—Rappaport reckons we can reap the benefits within a generation. To this end, the US National Institutes of Health has set up an exposure biology program. "We 're looking for interactions between genes and exposure to work out an individual's risk of disease," says David Balshaw, who manages the program. "It would allow you to tailor(使合适)the therapeutic response to that person's risk." An understanding of this interaction, reflected in a person's metabolic(新陈代谢的)profiles(数据图表), might also help predict how they will respond to a drug. Nicholson has been looking for clues in metabolite profiles of urine samples.G)Last year, his research group used these profiles to predict how individuals would metabolise paracetamol(扑热息痛). "It turned out that gut(肠子)microbes(微生物)were very important," says Nicholson. "We've shown that the pre-dose urinary metabolite profile could predict the metabolism of painkilling drugs, and therefore predict drug toxicity." The findings suggest that metabolic profiles of exposure could help doctors tailor therapies and enable them to prescribe personalized medicines. Justin Stebbing at Imperial College London has already shown that metabolic profiles of women with breast cancer can predict who will respond to certain therapies. It is early days, but the initial findings look promising. "We're reaching the point where we're capable of assessing the exposome," says Balshaw. With the implications for understanding disease causes and risks, and a real prospect of developing personalized medicine, the expo-some is showing more promise than the genome already, he adds.H)How does air pollution or stress leave a trace in the blood? The US National Institutes of Health in Bethesda, Maryland, is trying to find out. One group funded by the NIH and led by Nongjian Tao at Arizona State University's Biodesign Institute in Tempre is developing wearable wireless sensors to monitor an individual' s exposure to environmental pollutants. Tao' s team started by creating software for Windows phones(视窗话筒), but they are working on apps(应用程序)that could be used on any smart phone. In theory, anyone could pop on(戴)a sensor and download an app to receive real-time information on exposure to environmental pollutants. At the same time, smart phones monitoring your location can combine the level of pollution with an exact time and place. Tao presented his sensor at the Circuits and Systems for Medical and Environmental Applications Workshop in Yucatan Mexico last week. I)"We're now moving prototypes(原型，样品)into human studies, and progressing those prototypes into products," says David Balshaw of the NIH. Earlier this year, Tao' s group tried out the sensor on individuals taking a stroll around Los Angeles, California. They were able to measure how exposure to pollutants changed as each person wandered near busy roads and petrol stations.
Directions: In recent years, many companies are inclined to recruit experienced employees because they can reduce training cost and make quick profits. However, some people are against this sort of recruiting requirement. Please write a short essay entitled Should Companies Only Focus on Experience. You should write at least 120 words but no more than 180 words.
Most people often dream at night. When they wake in the morning they say to themselves, "What a strange dream I had! I wonder what made me dream that." Sometimes【C1】______are frightening. Sometimes, in dreams, wishes come true. At other times we are troubled by strange dreams in which the world seems to have been【C2】______upside-down and nothing makes sense. In dreams we do things which we would never do when we're【C3】______. We think and say things we would never think and say. Why are dreams so strange and【C4】______? Where do dreams come from? No one has produced a more satisfying【C5】______than a man called Sigmund Freud. He said that dreams come from a part of one's mind which one can neither recognize nor control. He【C6】______this the "unconscious mind." The new worlds Freud【C7】______were inside man himself. For the unconscious mind is like a deep well, full of memories and feelings. These memories and feelings have been stored there from the【C8】______of our birth. Our conscious mind has forgotten them. We do not know that they are there until some unhappy or unusual experience causes us to remember, or to dream dreams. Then【C9】______we see the same thing and feel the same way we felt when we were little children. The unconscious forces inside us are at least as powerful as the conscious forces we know about. Sometimes we do things without knowing Why. If we don't, the reasons may lie【C10】______in our unconscious minds.
