Pregnant Women Warned About ACE Inhibitor
Some of the most commonly used medicines for high blood pressure are drugs called ACE in-hibitors. Doctors have given these drugs to patients for twenty-flve years. A government study in the United States found that the use almost doubled between 1995 and 2000.
Doctors have known for years that women should not take ACE inhibitors during the last six months of pregnancy. The medicine can injure the baby. ACE inhibitors, though, have been con-sidered safe when taken during the first three months. But a new study has found that women who take these drugs early in their pregnancy still increase the risk of birth disorders. The study shows that, compared to others, their babies were almost three times as likely to be born with major problems. These included problems with the formation of the brain and nervous system and holes in the heart.
The researchers say they found no increased risk in women who took other blood pressure medicines during the first three months. Researchers at Vanderbilt University in Tennessee and Boston University did the study. The New England Journal of Medicine published the results. The researchers studied the records of almost thirty thousand births between 1985 and 2000. Two hundred nine babies were born to women who took ACE inhibitors during the first three months of their pregnancies. Eighteen of the babies, or almost nine percent, had major disorders.
ACE inhibitors are often given to patients with diabetes. But diabetes during pregnancy can result in birth defects. So the study did not include any women known to be diabetic. ACE inhibitors suppress a protein called angiotensin-converting enzyme or ACE. This enzyme produces a chemical in the body that makes blood passages narrow. The drugs increase the flow of blood so pressure is reduced.
New drugs are tested on pregnant animals to see if they might cause birth defects in humans.But experts say these tests are not always dependable. The United States Food and Drug Adminis-tration helped pay for the study. The F. D. A. says women who might become pregnant should talk with their doctor about other ways to treat high blood pressure.

McGrady&39;s art is a spectacle
1. When Tracy McGrady is healthy, his play can be so beautiful that even his own teammates on the court cannot help but admire it in the middle of a game.
2. "It&39;s hard for me, because I&39;m a fan of basketball, " Houston point guard Rarer Alston told the Houston Chronicle newspaper after McGrady&39;s 44 point performance against Utah on January 5. "When he&39;s shooting the ball like that, a lot of times I&39;m standing there watching and, all of a sudden, the other team&39;s getting the
ball and going on a fast break, and I&39;m getting yelled at by the coach." Indeed, McGrady&39;s body control, his energy, his shooting-watching these are like watching an artist at work, blending colors, constructing sentences, or playing music.
3. Unfortunately, McGrady, 27, hasn&39;t always been on the job. Already this season, he&39;s missed seven games with back spasms. After Yao Ming was injured on Dec. 23, it appeared Houston would be without both of its stars. McGrady, however, returned three days later and has been playing well ever since, scoring more than 30 points in each of the last six games, as of Tuesday. Houston can&39;t seem to get on without him. When McGrady was injured, the Rockets won two and lost five.
4. “Listen, there are only four or five people on the entire planet that can do the things he can do with the basketball, " forward Shane Battier said of McGrady. " From a fan&39;s perspective and we&39;re fans even though we&39;re players it&39;s really fun to watch him do that." From a player&39;s perspective, his game can affect the entire team. No question. We see him, and we get excited, and that pumps us up. lie keeps making shots, and suddenly it seems to become easier for everybody.
5. But it won&39;t, really. Houston has just begun an important stretch on their schedule. Four of the next seven games will be played away from Houston and without Yao. Six of the games will be against teams with winning records. Opponents will double-team McGrady in an attempt to dull the impact of his art. Instead of watching, McGrady&39;s teammates will need to create a little art of their own.

Problems of College Students
Today&39;s college students are more narcissistic (自恋的 ) and self-centered than their predecessors, according to a comprehensive new study by five psychologists who worry that the trend could be harmful to personal relationships and American society.
"We need to stop endlessly repeating &39;You&39;re special&39; and having children repeat that back, " said the study&39;s lead author, Professor Jean Twenge of San Diego State University. "Kids are self-centered enough already." "Unfortunately, narcissism can also have very negative consequences for society, including the breakdown of close relationships with others, " he said. The study asserts that narcissists "are more likely to have romantic relationships that are short-lived, at risk for infidelity, lack emotional warmth, and to exhibit game-playing, dishonesty, and over-controlling and violent behaviors." Twenge, the author of "Generation Me : Why Today&39;s Young Americans Are More Confident, Assertive, Entitled--and More Miserable Than Ever Before" , said narcissists tend to lack empathy, react aggressively to criticism and favor self-promotion over helping others.
Some analysts have commended today&39;s young people for increased commitment to volunteer work. But Twenge viewed even this phenomenon skeptically, noting that many high schools require community service and many youths feel pressure to list such endeavors on college applications.
Campbell said the narcissism upsurge seemed so pronounced (非常明显的 ) that he was unsure if there were obvious remedies. "Permissiveness seems to be a component, " he said. "A potential antidote would be more authoritative parenting. Less indulgence might be called for."
Yet students, while acknowledging some legitimacy to such findings, don&39;t necessarily accept negative generalizations about their generation.
Hanady Kader, a University of Washington senior, said she worked unpaid last summer helping resettle refugees and considers many of her peers to be civic-minded. But she is dismayed (气馁; 灰心) by the competitiveness of some students who seem prematurely focused on career status. "We&39;re encouraged a lot to be individuals and go out there and do what you want, and nobody should stand in your way, " Kader said. "I can see goals and ambitions getting in the way of other things like relationships."
Kari Dalane, a University of Vermont sophomore, says most of her contemporaries are politically active and not overly self-centered. "People are worried about themselves--but in the sense of where they&39;re going to find a place in the world, " she said. "People want to look their best, have a good time, but it doesn&39;t mean they&39;re not concerned about the rest of the world."
Besides, some of the responses on the narcissism test might not be worrisome, Dalane said. "It would be more depressing if people answered, &39;No, I&39;m not special.&39;"

Taking Naps
American society is not nap (午睡) -friendly. "In fact", says David Dinges, a sleep spe.cialist at the University Of Pennsylvania School Of Medicine, "there&39;s even a prohibition against admitting we need sleep." Nobody wants to be caught napping or found asleep at work. To quote a proverb:
"Some sleep five hours, nature requires seven, laziness nine and wickedness eleven."
Wrong. The way not to fall asleep at work is to take naps when you need them. "We have to totally change our attitude toward napping," says Dr. William Dement of Stanford University, the godfather of sleep research.
Last year a national commission led by Dement identified an "American sleep debt" which one member said was as important as the national debt. The commission was concerned about the dangers of sleepiness: people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, president Clinton is trying to take a half-hour snooze (打瞌睡) every afternoon.
About 60 percent of American adults nap when given the opportunity. We seem to have "a mid-afternoon quiet phase" also called "a secondary sleep gate". Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap.
We Superstars of Snooze don&39;t nap to replace lost shut-eye or to prepare for a night shift.
Rather, we "snack" on sleep, whenever, wherever and at whatever time we feel like it. I myself have napped in buses, ears, planes and on boats; on floors and beds; and in libraries, offices and museums.
It is commonly accepted in American society that too much sleep is 查看材料
