Better Control of TB Seen If a Faster Cure Is Found
The World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis（结核病）.Most times , the infection remains inactive（不活跃
的）.But each year about eight million people develop active cases of TB,usually in their lungs. Two million people die of it.The disease has increased with the spread of AIDS and drug-resist-ant forms of tuberculosis.
Current treatments take at least six months.Patients have to take a combination of several antibiotic（抗生素）drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection（传染病）that resists treatment. Public health experts agree that a faster-act-ing cure for tuberculosis would be more effective.Now a study estimates just how effective it might be .A professor of international health at Harvard University led the study.Joshua Salomon says a shorter treatment program would likely mean not just more patients cured.It would also mean fe- wer infectious patients who can pass on their infection to others.
The researchers developed a mathematical（数学的）model to examine the effects of a two-month treatment plan.They tested the model with current TB conditions in Southeast Asia.The scientists found that a two-month treatment could prevent about twenty percent of new cases.And it might prevent about twenty-five percent of TB deaths.The model shows that these reductions would take place between two thousand twelve and two thousand thirty.That is,if a faster cure is developed and in wide use by two thousand twelve.
The World Health Organization developed the DOTS program in nineteen ninety.DOTS（短期直接观察治疗）is Directly Observed Treatment, Short-course. Health workers watch tubercu- losis patients take their daily pills to make sure they continue treatment.
Earlier this year,an international partnership of organizations announced a plan to expand the DOTS program.The ten-year plan also aims to finance research into new TB drugs.The four most common drugs used now are more than forty years old.The Global Alliance for TB Drug De- velopment（全球结核病药物开发联盟）says its long-term goal is a treatment that could work in as few as ten doses.

Which of the following statements is NOT right in Paragraph 2?
A: Current treatments of TB take at least six months.
B: Shorter treatment program would likely mean more patients cured,and fewer infectious patients.
C:The patients have to take a combination of several antibiotic drugs daily.
D: The patients should stop taking antibiotic drugs as soon as they feel better.

Some Sleep Drugs Do More Than Make You Sleep
The United States Food and Drug Administration(FDA)has ordered companies to place strong new warnings on thirteen drugs that treat sleep disorders.It also ordered the makers of the sleeping pills to provide information for patients explaining how to safely use the drugs.
Last Wednesday,the FDA announced that some of these drugs can have unexpected and dangerouseffects.These include the risk of life-threatening allergic（过敏性的）reactions.They also include rareincidents of strange behavior.These include people cooking food,eating and even driving while asleep.The patients later had no memory of doing these activities while asleep.
Last year,a member of the United States Congress said he had a sleep-driving incident.PatrickKennedy , a representative from Rhode Island,crashed his car into a security barrier near the building wherelawmakers meet.The accident happened in the middle of the night and no one was hurt.Mr.Kennedy saidhe had earlier taken a sleep medicine.He said he was also being treated with a stomach sickness drug thatcan cause sleepiness.
The FDA did not say in its announcement how many cases of sleep-driving it has documented.However,the New York Times reported last year about people who said they had strange sleep events after taking the drug Ambien.Some reported sleep-driving and sleep-walking.Others said they found evidence after waking in the morning that they had cooked food or eaten in their sleep.But they had no memory of carrying out the activities.
An FDA official says that these serious side effects of sleep disorder drugs appear to be rare.But,he also said there are probably more cases than are reported.He said the agency believes the risk of such behaviors could be reduced if people take the drugs as directed and do not drink alcohol while taking the drugs.The FDA has advised drug companies to carry out studies to investigate the problem.

The FDA announced that______.
A:thirteen drug companies were closed last Wednesday
B:only thirteen drugs could treat sleeping disorders
C:some sleep drugs could lead to serious side effects
D:some makers of sleeping pills provided false information to their patients

Hypertension Drugs Found to Cut Risk of Stroke
Australian doctors declared Monday that a cocktail of simple antihypertensive drugs can lower the risk of patients suffering a repeat stroke by more than a third.This is the result of their research.The research, presented at a medical conference in Italy over the weekend,has been valued highly as a major breakthrough in stroke prevention.
Strokes kill 5 million people a year,and more than 15 million suffer non-fatal strokes that often leave them with useless limbs,slurred speech and other serious disabilities.One in five stroke survivors goes on to have a second,often fatal,stroke within five years of the first.
An international six-year study of 6,100 patients directed from Sydney University found that by taking two blood pressure-lowering drugs,the risk of secondary strokes can be reduced by up to 40 percent.Even taking one of the commonly available drugs can cut the risk by a third,the study said.The drugs are the diuretic indapamide ( 吲达帕胺）and the ACE inhibitor perindopril , better known by its brand name Cover- syl.The combination was effective even in patients who did not have high blood pressure,the researchers said.They even found that the risk of another stroke could be cut by three quarters among the one-in-ten pa- tients who had suffered a cerebral hemorrhage（出血）, the worst type of stroke , where there is direct bleeding into the brain.
Stephen McMahon,who presented the research at the Milan congress of the European Society of Hypertension,said about 50 million people were alive who had suffered at least one stroke."If most of those patients were able to get access to this treatment,it would result in maybe the avoidance of half a million strokes a year,"the professor told Australia's ABC Radio.
McMahon said doctors had long known that lowering the blood pressure of those with hypertension could help prevent strokes."What we have shown for the first time is that it does not really matter what your blood pressure is;if you have had a stroke,then lowering blood pressure will produce large benefits,to begin with-even for people whose blood pressure is average or below average,"he said.
McMahon said the Milan gathering had heralded the research as a"major breakthrough in the care of patients with strokes-perhaps the biggest step forward that we have made in the last couple of decades."

What patients among those who have a stroke will benefit greatly from taking blood pressure-lowering drugs?
A:Those whose blood pressure is high.
B:Those whose blood pressure is average.
C:Those whose blood pressure is below average.
D:All of the above.
