单选题1. After - birth Depression Blamed for Woman's Suicide A new mother apparently suffering from postpartum mental illness fell to her death from a narrow 12th--floor ledge of a Chicago hotel, eluding the lunging grasp of firemen called to help. The Chicago Tribune reported Tuesday that the mother of a 3 - month - old daughter, Melanie Stokes, 41, was said to be suffering from a severe form of after- birth depression called postpartum psychosis, an extremely rare biological response to rapidly changing hormonal levels that can result in hallucinations (幻觉), delusions (妄想), severe insomnia (失眠) and a drastic departure from reality. "That was a monster in my daughter' s brain. " said Stokes' mother, Carol Blocker. "The medicine took no effect at all. while her grief was so strong that nothing could make up for it. I'm just glad she didn't take her daughter with her. " Virtually all new mothers get postpartum blues, also called the "baby blues", which are brief episodes of irritability, moodiness and weepiness. About 20 percent of birthing women experience postpartum depression, which can be triggered by hormonal changes, sleeplessness and the pressures of being a new mother. It is often temporary and highly treatable. But The Tribune said what scientists suspect Stokes was battling, postpartum psychosis, is even more extreme and is considered a psychiatric emergency. "During postpartum psychosis--a very real disorder that affects less than 1 percent of women, according to the National Institute of Mental Health--a mother might hear voices, have visions, feel extremely agitated and be at risk of harming the child or herself. Often the consequences are tragic. In 1987, Sheryl Masip of California told a judge that postpartum psychosis made her drive a Volvo over her 6 - week - old son. Latrena Pixley of Washington, D. C. , said the disorder was why she smothered her 6 -week -old daughter in 1992. And last year, Judy Kirby, a 31 - year - old Indianapolis mother allegedly suffering from postpartum psychosis, sped into oncoming traffic and plowed into a minivan, killing seven youngsters, including three of her own.

单选题Drug Resistance Fades Quickly in Key AIDS Drug One of the main weapons to prevent mother-to-child transmission of the AIDS virus during birth is the drug nevirapine. But when nevirapine is used alone just once, HIV starts becoming resistant to it. Research in Botswana shows that the resistance is not long lasting and that this affordable drug does not have to be abandoned forever by infected mothers who have already taken it. International medical guidelines call for pregnant women with advanced HIV to get a combination of AIDS drugs including nevirapine to prevent passing their infection on to their newborns during delivery. But in poor countries, combinations have been expensive and nevirapine has often been used alone, since studies have shown that a single dose can cut the transmission rate in half. The problem is that HIV resistance builds against it quickly when used alone just once because other drugs are not present to kill the virus particles that survive nevirapine. This renders the drug less effective in later combinations for treating women after their baby is born. But the new study from Botswana shows that nevirapine can make a comeback for these women if they wait until the resistance subsides. "The further out you get from that exposure to single dose nevirapine, the less detectable nevirapine resistance is, " said Shahin Lockman of the Harvard School of Public Health in Boston. She says waiting period for women who get the single dose of nevirapine at delivery can be as short as six months. "If they started nevirapine-based treatment six or more months after nevirapine exposure, their treatment response was just as good, and really quite high, compared to women who did not have the single dose of nevirapine, " she added. "However, the women who started nevirapine-based treatment within six months of that nevirapine exposure were much more likely to experience treatment failure. " The study published in the New England Journal of Medicine shows that waiting at least six months means that HIV-positive women are 70 percent more likely to benefit from nevirapine-based drug combinations again than women who get them sooner. An official with the U. S. government health agency that helped fund the study calls it very important. Lynne Mofenson is chief of research on child, adolescent, and maternal AIDS at the U. S. National Institute of Child Health and Human Development. She says the finding supports a World Health Organization (WHO) recommendation restricting a single dose of nevirapine only to pregnant HIV-infected women who are healthy enough to wait six months after childbirth for more nevirapine-based therapy. Otherwise, they should get other drugs during labor. "It shows the importance of screening women for treatment while they are pregnant and putting them on appropriate therapy while they are pregnant to avoid having to start them too soon after they received preventive therapy, " she explained. Shahin Lockman in Boston says the problem of nevirapine resistance should diminish now that more and more people are receiving combinations of AIDS drugs under expanded U. S. and international programs to deliver them to Africa and other regions hard hit by the virus.

单选题 Double Effect The Supreme Court's decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering. Although it ruled that there is no constitutional right to physician-assisted suicide, the Court in effect supported the medical principle of "double effect", a centuries-old moral principle holding that an action having two effects—a good one that is intended and a harmful one that is foreseen—is permissible if the actor intends only the good effect. Doctors have used that principle in recent years to justify using high doses of morphine to control terminally ill patients' pain, even though increasing dosages will eventually kill the patient. Nancy Dubier, director of Montefiore Medical Center, contends that the principle will shield doctors who "until now have very, very strongly insisted that they could not give patients sufficient mediation to control their pain if that might hasten death." George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. "It's like surgery," he says. "We don't call those deaths homicides because the doctors didn't intend to kill their patients, although they risked their death. If you're a physician, you can risk your patient's suicide as long as you don't intend their suicide." On another level, many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying. Just three weeks before the Court's ruling on physician-assisted suicide, the National Academy of Science (NAS) released a two-volume report, Approaching Death: Improving Care at the End of Life. It identifies the under-treatment of pain and the aggressive use of "ineffectual and forced medical procedures that may prolong and even dishonor the period of dying" as the twin problems of end-of-life care. The profession is taking steps to require young doctors to train in hospices, to test knowledge of aggressive pain management therapies, to develop a Medicare billing code for hospital-based care, and to develop new standards for assessing and treating pain at the end of life. Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care. "Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering," to the extent that it constitutes "systematic patient abuse." He says medical licensing boards "must make it clear that painful deaths are presumptively ones that are incompetently managed and should result in license suspension."

French influence on this continent thus came to an end; England now controlled most of North America. But the war had been long and expensive. England had many debts. George Ⅲ, King of England, after consulting with his advisers, decided that the American colonists (殖民者) should help pay some of the expenses of this war. A standing English army of 10,000 men had been left in the colonies(殖民地)for protection against the Indians. The English government also felt that the colonists should share in the expenses of maintaining this army. The result was a series of measure, the Grenville Program, passed by Parliament and designed to raise money in the colonies. Some of these measures were accepted by The colonists, but one in particular, the Stamp Act, was met with great protest. The Stamp Act required that’s tamps, ranging in price from a few cents to almost a dollar, be placed on all newspapers, advertisements, bills of sale, wills, legal papers, etc. the Stamp Act was one of the causes of the American Revolution. It affected everyone, rich and poor alike. Some businessmen felt that the act would surely ruin their businesses. Of all the voices raised in protest to the Stamp Act, none had greater effect than that of a young layer from Virginia-Patrick Henry. Henry had only recently been elected to the Virginia Assembly. Yet when the Stamp Act came up for discussion, he opposed it almost single handedly. He also expressed, for the first time, certain ideas that were held by many Americans of the time but that never before had been stated so openly. "Is life so dear or peace so sweet, as to be bought at the price of chains and slavery? Forbid it, Almighty(万能的) God! I know not what course others may take, but as for me, give me liberty, or give me death!"

单选题Since 2000, the number of college students dieting, vomiting, or taking laxatives to lose weight has jumped from about 28 to 38 percent, according to the American College Health Association's annual surveys. Well - balanced caloric intake, with regular meals and physical activity - not dieting -is the best way to avoid obesity, says Kreipe, a professor at the University of Rochester Medical Center. That's why, in his view, calorie information doesn't benefit students. "Nutrition is not a simple thing that can be distilled (提炼) down into a label, "he says.

单选题The Place too Effect When scientists want to test a new drug，they usually divide a large number of people 16 two groups. One group takes the medicine and the other takes a substance 17 as a placebo (安慰剂). It may contain nothing more than sugar. The people do not know which pill they are taking, the active one or the inactive one. In this kind of experiment, the medicine must perform 18 than the placebo to prove it is effective. Yet, people who take a placebo sometimes experience improvements in their health. This is known as "the placebo effect" —the effect of something 19 is not supposed to have any effect. Some doctors even use the placebo effect in their treatments. They might tell patients that a new drug will stop their pain. The patient does not know that the pills are 20 . The patient 21 the pills and later tells the doctor that the pain is gone. Now research in Sweden suggests that placebo treatments can also 22 the emotional effects of unpleasant experiences. The effects in the brain were similar to those seen when placebos have been used to ease pain. The researchers say that in both cases expectations of improvement are a major 23 on the effectiveness of placebos. The new study involved a group of people who looked at unpleasant pictures, 24 images of dead bodies. Predrag Petrovic of the Karolinska Institute in Stockholm led the study. The findings appeared in the publication Neuron (神经元). An influential study on placebos appeared in 1955. It said treatment with a placebo 25 patients feel better 35% of the time. But in 2001, Danish researchers reported that they had examined more than 100 studies. They found 26 evidence of healing as a result of placebos. Some researchers think a good relationship between a doctor and patient can increase the effectiveness of real medicines. In any case, some medical researchers are against the use of 27 . They think it is 28 to give some people inactive substances when testing new medicines. They say it would be better to 29 new drugs with existing drugs. That way, a study would show 30 the new drug is more effective.
