Researchers at Pittsburgh University School of Medicine examined 20 patients who had severe heart failure and were going to have surgery. They injected stem cells into the parts of their hearts that were damaged. They then compared their hearts with those of people who had undergone surgery without having the stem cells injected into them (they had also suffered from severe heart failure). The patients who had had the stem cells injected had hearts that were able to pump (用泵抽运) more blood than the others. According to Professor Robert Kormos, one of the researchers, these results could revolutionize heart treatment. Although previous studies had indicated that there might be a benefit, this is the first study that has actually proved that stem cell therapy can help the failing heart work better. All the patients in this study had hearts that could not pump blood properly. The scientists measured their ejection fraction (射血分数). This is a measure of heart performance; you measure how much blood is being pumped out by the left ventricle (心室). Healthy people's ejection fraction is about 55%. These patients had ejection fraction of under 35%. They all had by-pass surgery (搭桥手术) performed on them. Some of the patients had stem cells taken from their hip bones and injected into 25-30 sites in the damaged heart muscle. Six months later their ejection fraction rate was 46.1% while those who just had surgery but no stem cell injections averaged 37.2%. No side effects were reported. Heart failure is a common problem all over the world. In the UK alone about 650,000 people suffer from heart failure every year. As the number of people suffering from heart failure increases in the world in general these findings are particularly significant. Current treatments relieve the symptoms. This new stem cell therapy actually repairs the damaged muscle in the heart and has the potential of curing the disease.

单选题 U. S. States Do Poorly in Women's Health Not a single U. S. state meets basic federal goals for women's health, and the nation as a whole fails except in two areas—mammograms and dental check-ups—researchers said on Thursday. Millions of women lack health insurance, and states make it difficult to enroll in Medicaid, the state-federal health insurance plan for the poor, according to the report. And few states are doing anywhere near enough to help women quit smoking—the leading cause of death in the United States. "The nation as a whole and the individual states fall short of meeting national goals," reads the report. Put together by the National Women's Law Center and the Oregon Health Science University, "These health goals provide a road map for assessing the status of women's health." Of 27 measures examined by the group, from screening for diseases to actually treating them, the nation passes on only two, the researchers said. "The nation is so far from the healthy people goals that it receives an overall grade of 'unsatisfactory'," they wrote. The problem seems to be a lack among states of an overall plan for health in general, the NWLC said. "State policy makers' piecemeal approach to our health care crisis has resulted in a complex and ineffective system that fails to meet the health care needs of women," Judy Waxman, NWLC Vice President for Health, said in a statement. "Lawmakers need to take a comprehensive, long-term approach to meeting women's health needs and tackle this serious problem that plagues so many families."

单选题Deaf and Hearing Loss People who begin to go deaf in adult life have different problems from those who are horn deaf. They have to learn different ways of behaving and different ways of communication—perhaps at a time when learning is not all that easy. A hearing aid is not a complete solution to the problem. The sound perceived by the deaf person through a hearing aid is distorted and appears to have more background noise than is heard by someone with normal hearing. Deafened people have to lipread as well. Lipreading is difficult, demands intense concentration, and an uninterrupted direct view of the speaker's face. No other activities can take place at the same time: the lipreader has to stop eating, stop everything in order to concentrate on hearing. It is not a question of stupidity or bad temper—as it sometimes appears to be—but a question of being very easy to misunderstand when the sound is distorted. Remember what it's like trying to communicate on a very bad telephone line. Frustrating, isn't it? The deaf have to face all the time. A useful way of looking at the problem is to see the deaf person as a foreigner—to treat them as of you were in a foreign country. You would speak more clearly, slowly and raise your voice slightly. And you'd use gestures to make your meaning clear, as well as have no hesitation in using pencil and paper to be absolutely certain. You can do all those things with the deaf—as well as making sure you don't obscure your mouth with your hand, a pipe or a cigarette. Another point quite often overlooked is that a hearing aid may be quite efficient and useful in a quite carpeted room—but try it in the high street in the rush hour, in a noisy car, in a railway station ticket office, a cinema or a concert hail and you've got a really difficult problem to distinguish speech. So don't suggest to or encourage deaf people to go to functions which are going to make their disability appear worse—and increase their sense of failure. On the other hand careful selection of cinemas with good sound systems is important and you should experiment to find out where the best seats are for hearing, fitting adaptors for radio and television, observing which friends are easier to understand, and making sure that people talking are well-lit and all useful and positive activities.

They tend to believe, incorrectly, that their headaches are like everyone else's and they will only be "bothering(打扰，麻烦)" the doctor. "When should somebody seek medical help for headaches? neurologist Seymour Diamond asks rhetorically (提出问题进行探讨). Generally, whenever headaches are associated with neurological signs, such as dizziness(头昏，头晕), weakness in a limb or limbs, vision impairment of any sort—including seeing flashing lights—they warrant(应受) immediate attention. Additionally, Diamond says that you should seek medical attention: If you suffer from almost daily headaches; If the headache is a type you've never had before, or there has been a change in the character(特征) of the headache; If you're losing time from work or activities, or otherwise being prevented from functioning. Even if your headaches are less dramatic than those described here, if they are a re- al problem to you, you should seek help. It may be that your doctor will be unable to find a physical cause for your discomfort, but that may point you in other directions to find relief. Some headaches, particularly those caused by tension, have a major psycho- logical component that might be relieved through counseling (走向，指导).

The adolescent(少年)usually loves soft drinks for their sweetness and variety. He knows nothing of sadness and his taste of life is sweetness to the exclusion of all the others. In his eyes, the world is full of facets just as soft drinks are varied in flavor. Youth sees him on a job or in love. Now, soft drinks will have to give way to coffee, which is bitter yet somewhat sweet and fragrant. It gives a stimulating sensation suggestive of maturity, appealing to him, as he is fickle and moody. At his stage, he begins his career full of ambition and ideals, on the other hand he also needs and aspires after a home of his own. However, either his work or his love affairs may bring small setbacks, for which he is sometimes seen forcing a tearful smile and sometimes smiling through his tears. Considerations of gains and losses seem to him an enjoyment as well as a torture. Middle age turns him to Chinese tea that gives a delicate fragrance very gradual to come out, only discernable off and on. It is bland an elegant, deep and profound. It never stimulates your sense of taste but a lip of it will leave a faint fragrance lingering in your mouth, Free from impractical longings and fully aware of the evanescent of the sunset, he cherishes every minute of the day and each day of his is sweetened with a simple but real happiness. The elderly drinks plain boiled water which is devoid of saccharin, caffeine or theophyline (茶碱). It tastes insipid yet a slow sipping will doubtless yield a wee bit of sweetness. He has been tossed in life's storms and taught by rough and bitter experience to know better than to care about glories and successes which appear to him now as transient as a fleeting cloud. For this is the time he can sit comfortable in an armchair letting his mind wander. All that happened in the past and all that exist in the world seem to him as plain and insipd as water...
