1 Aromatherapy is a form of alternative medicine which is based on the use of very concentrated essential oils from the flowers,leaves,bark,branches or roots of plants which are considered to have healing ptoperties.In aromatherapy these powerful oils are mixed with other oils,such as almond(杏仁)oil,or they are diluted(稀释)with water.These solutions(溶液剂)can be rubbed on the skin,sprayed in the air,or applied as a compress(敷药)。
2 Many people have aroatherapy massages(按摩),and depending on the treatment aperson is having,the aroatherapist will massage the oil into the hands or shoulders.The massage is smooth and flowing,as it is designed to create a sense of relaxation and calm.The sessions are tailored to the individual's health and mood at rhe time,so every session is unique.
3 Practioners of aromatherapy believe that the aroma of the essential oils directy stimulates the brain or that the oils are absorbed through the skin into the bloodstream,where they can affect the whole body and promote healing.Other claims in support of aromatherapy are that it aids digestion,imtproves the functiong of respiratory system,reduces muscular aches and pains,and promotes muscle relaxation and tone.It has also been argued that aromatherapy can improve circulation,lower blood pressure,and help combat insomia(失眠)and other stress-related disorders such as tension headaches,anxiety,and mild depression.
4 However,while aroatherapy may hace real effects that promate a sense of well-being,some tradional medicine practitioners remain doubtful about its powers.While research has confirmed that aroatherapy does have some positive short-term effects on most people,it also suggests that aroatherapy is not an actual science or medicine that should be used to treat illness.Furthermore,not all aroatherapy is considered beneficial to health.There are precautions which shoula be taken bofore having aroatherapy because some oils can have negative effets on people with certain medical conditions.The study of aroatherapy is relatively new and unexplored.More research needs to be conducted to make scientific conclusions about its use and effects.

A.New Strategy to Overcome Breast Cancer
Post-menopausal(绝经后)women who walk for an hour a day can cut their chance of breast cancer significantly,a study has suggested. The report ,which followed 73,000 women for 17 years,found walking for at least seven hours a week lowered the risk of the disease.The American Cancer Society team said this was the first time reduced risk was specifically linked to walking. UK experts said it was more evidence that lifestyle influenced cancer risk.
A.recent poll for the charity Ramblers a quarter of adults walk for no more than an hour a week,but being active is known to reduce the risk of a number of cancers.This study, published in Cancer Epidemiology,Biomarkers&Prevention,followed 73.615 women out of 97,785 aged 50-74 who had been recruited by the American Cancer Society between 1992 and 1993,so it could monitor the incidence of cancer in the group.
They were asked to complete questionnaires on their health and on how much time they were active and participating in activities such as walking,swimming and aerobics(有氧运动)and how much time they spent sitting watching television or reading.They completed the same questionnaires at two-year intervals between 1997 and 2009.Of the women,47% said walking was their only recreational acivity.Those who walked for at least seven hours per week had a 14% lower risk of breast cancer compared to those who walked three or fewer hours per week.
Dr.Alpa Patel,a senior epidemiologist at the American Cancer Society in Atlanta,Georgia,who led the study,said:”Given that more than 60% of women report some daily walking,promoting walking as a healthy leisure-time activity could be an effective strategy for increasing physical activity amongst post-menopausal women.We were pleased to find that without any other recreational activity, just walking one hour a day was associated with a lower risk of breast cancer in these women.””More strenuous(紧张的)and longer activities lowered the risk even more.
Baroness Delyth Morgan, chief executive of Breast Cancer Campaign,said:”This study adds further evidence that our lifestyle choices can play a part in influencing the risk of breast cancer and even small changes incorporate into our normal day-to-day activity can make a difference.”
She added:”We know that the best weapon to overcoming breast cancer is the ability to stop it occurring in the first place. The challenge now is how we turn these findings into action and identify other sustainable lifestyle changes that will help us prevent breast cancer.”

First Self-contained Heart Implanted 【首例整套人工心脏移植】
A.patient on the brink of death has received the world’s first self-contained artificial heart—a battery-powered device about the size of a softball that runs without the need for wires, tubes or hoses sticking out of the chest.
Two surgeons from the University of Louisville implanted the titanium and plastic pump during a sever-hour operation at Jewish Hospital Monday. The hospital said the patient was “awake and responsive” Tuesday and resting comfortably. It refused to release personal details.
The patient had been expected to die within a month without the operation, and doctors said they expected the artificial heart to extend the person’s life by only a month. But the device is considered a major step toward improving the patient’s quality of life.
The new pump, called AbioCor, is also a technological leap from the mechanical hearts used in the 1980s, which were attached by wires and tubes to bulky machinery outside the body. The most famous of those, the Jarvic-7, used air as a pumping device and was attached to an apparatus about the size of a washing machine.
“I think it’s potentially a major step forward in the artificial heart development,” said Dr. David Faxon, president of the American heart Association. However, he said the dream of an implantable, permanent artificial heart is not yet a reality: “This is obviously an experimental device whose long-term success has to be demonstrated.” Only about half of the 4,200 Americans on a waiting list for donor hearts received them last year, and most of the rest died.
Some doctors, including Robert Higgins, chairman of cardiology at the Medical College of Virginia in Richmond, said artificial hearts are unlikely to replace donor hears.
“A donor heart in a good transplant can last 15 to 30 years,” he said. “It’s going to be hard to replace that with a machine.”
The AbilCor has a 2-pound pumping unit, and electronic controls that adjust the pumping speed based on the body’s needs. It is powered by a small battery pack worn outside the body that transmits current through the skin.

Wrongly Convicted Man and His Accuser Tell Their Story
NEW YORK,NY, January 5,2010. St.Martin’s Press has announced the release of the paperback edition of Picking Cotton, a remarkable true story of what novelist John Grisham calls an “account of violence, rage, redemption(救赎)，and, ultimately forgiveness.”
The story began in 1987, in Burlington, North Carolina, with the rape of a young while college student named Jennifer Thompson. During her ordeal, Thompson swore to herself that she would never forget the face of her rapist, a man who climbed through the window of her apartment and assaulted her brutally._During the attack, she made an effort to memorize eveery detail of his face, looking for scars, tattoos(纹身)，or other identifying marks.(46)When the police asked her if she could identify the assilant(袭击者)from a book of mug shots, she picked one that she was sure was correct, and later she identified the same man in a lineup.
Based on her convincing eyewithness testimony, a 22-year-old black man named Ronald Cotton was sentenced to prison for two life terms. Cotton’s lawyer appealed the decision, and by the time of the appeals hearing, evidence had come to light suggesting that the real rapist might have been a man who looked very like Cotton, an imprisoned criminal named Bobby Poole.Another trial was held.(47)Jennifer Thompson looked at both men face to face, and once again said that Ronald Cotton was the one who raped her.
Eleven years later, DNA evidence completely exonerated(证明……清白)Cotton and just as unequivocally(明确地) convicted Poole, who confessed to the crime. Thompson was shocked and devastated.(48) “The man I was so sure I had never seen in my life was the man who was inches from my throat, who raped me, who hurt me, who took my spirit away, who robbed me of my soul,” she wrote. “And the man I had identified so surely on so many occasions was absolutely innocent.”
_Jennifer Thompson decided to meet Cotton and apologize to him personally.(49) Remarkably both were able to put this tragedy behind them, overcome the racial barrier that divided them, and write a book, which they have subtitled “Our memoir of injustice and redemption.”
Nevertheless, Thompson says, she still lives “with constant pain that my profound mistake cost him so dearly_I cannot begin to imagine what would have happened had my mistaken identification occurred in a capital case_(50)”

More about Alzheimer's Disease
Scientists have developed skin tests that may be used in the future to identify people with Alzheimer's disease1 and may ultimately allow physicians to predict 46 is at risk of getting this neurological disorder.
' The only current means of 47 the disease in a living patient is a long and expensive series of tests that eliminate every other cause of dementia.
“ Since Alois Alzheimer described the 48 nearly a century ago，people have been trying to find a way to 49 diagnose it in its early stages，” said Patricia Grady，acting director of the National Institute of Neurological Disorders and Stroke in Bethesda, Maryland. "This discovery, if 50, could prove a big step forward in our efforts to deal with and understand the disease. ”
Alzheimer's is the single greatest 51 of mental deterioration in older people, affecting between 2. 5 million and 4 million people in the United States 52. The devastating disorder gradually destroys memory and the ability to function，and eventually causes death. There is currently no known 53 for the disease.
Researches 54 that the skin cells of Alzheimer' s patients have defects that interfere with their ability to regulate the flow of potassium in and out of the cells. The fact that the cell defects are present in the skin suggests that Alzheimer's 55 from physiological changes throughout the body，and that dementia may be the first noticeable effect 56 these changes as the defects affect the cells in the brain, scientists said.
The flow of potassium is especially 57 in cells responsible for memory formation. The scientists also found two other defects that affect the cells' supply of calcium, another critical element.
One test developed by researches calls 58 growing skin cells in a laboratory culture and then testing them with an electrical detector to determine if the microscopic tunnels that 59 the flow of potassium are open. Open potassium channels create a unique electrical signature.
A.spokesman for the Alzheimer's Association said that if the validity of the diagnostic test can be proven it would be an important 60, but cautioned that other promising tests for Alzheimer's have been disappointing.
