单选题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
1
more than a third. This is the result of their research. The research has been
2
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
3
them with useless limbs, broken speech and other serious disabilities. One in five stroke
4
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 up to 40 percent. Even taking one of the commonly
5
drugs can cut the risk by a third, the study said. The drugs in combination were
6
even in patients who did not have high blood pressure, the researchers said. They even found that the risk of another stroke could be
7
by three quarters among the one-in-ten patients who had suffered a cerebral hemorrhage (脑出血), the worst type of stroke,
8
there is direct bleeding into the brain.
Stephen McMahon, who
9
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
10
to this treatment, it would result
11
maybe the avoidance of half a million strokes a year," the professor told Australia"s ABC Radio.
McMahon said doctors had
12
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
13
what your blood pressure is; if you have had a stroke, then lowering blood pressure will produce large
14
, to begin with—even for people whose blood pressure is average or below average," he said.
McMahon said the Milan gathering had heralded (预示) the research as a "major breakthrough in the care of patients
15
strokes—perhaps the biggest step forward that we have made in the last couple of decades".

An Unusual Experience at
Sea{{/B}} It was early one morning in February 1972 when Mayoral
and his partner Santos Luis Perez set out to fish in Laguna San Ignacio.
Hundreds of gray whales were swimming in the three-mile-long, one-mile-wide
inlet. This was usual between December and April, for the whales breed in the
protected inlets of Baja, the final destination of their annual 6,000-mile
migration from the Arctic. Mayoral and Perez stayed as for as possible from the
spouting (喷涌) creatures, because the whales were said to smash boats with their
powerful flukes (鲸尾的叶). Mayoral, who had 16 years' experience at sea, knew no
one who had been close to a healthy gray whale and lived. As
Mayoral rowed to catch the outgoing (退出去的) tide, he saw, straight ahead, a whale
approaching. Heart pounding, the 31-year-old turned the little wooden boat and
pulled hard for shore. Try as he might, however, he could not row over the huge
beast. In moments, it overtook them. Expecting the worst, the fishermen dropped
to their knees and made the sign of the cross. The whale raised its nine-foot
head out of the water and looked at them. Then, remarkably, it began to rub
gently against the boat. Sinking and resurfacing (重新露出水面) on
opposite sides of the boat, the whale continued its gentle rubbing for almost an
hour. At first the men prayed, frozen in fear. But gradually Mayoral's terror
gave way to curiosity. He was tempted to reach out and touch this oddly
unthreatening monster, but a lifetime of caution kept him still.
At last, having finished with whatever its purpose had been, the whale
disappeared below the surface. Some time passed before either man spoke. Then
they headed home. To his wife, Mayoral said only, "No fish today."
But word spread through the cluster of small wooden houses near the
salt-water lake. A strange thing had happened: one of the whales had tried to
touch the men, and the men had returned unharmed. Why? In nights
to come, by faint kerosene lamps, Mayoral and Perez told the story. They and
other fishermen struggled to understand. What did the whale
want?

journals{{/B}} Medical journals are publications that report
medical information to physicians and other health professionals.
In the past, these journals were available only in print. With the
development of electronic publishing, many medical journals now have Web sites
on the Internet, and some journals publish only online. A few medical journals,
like the Journal of the American Medical Association, are considered general
medical journals because they cover many fields of medicine. Most medical
journals are specialty journals that focus on a particular area of
medicine. Medical journals publish many types of articles.
Research articles report the results of research studies on a range of topics
varying from the basic mechanisms of diseases to clinical trials that compare
out~ comes of different treatments. Review articles summarize and analyze the
information available on a specific topic based on a careful search of the
medical literature, Because the results of individual research
studies can be affected by many factors, combining results from different
studies on the same topic can be helpful in reaching conclusions about the
scientific evidence for preventing, diagnosing or treating a particular disease.
Case conferences and case reports may be published in medical journals to
educate physicians about particular illnesses and how to treat at them.
Editorials in medical journals are short essays that express the views of the
authors, often regarding a re- search or review article published in the same
issue. Editorials provide perspective on how the current article
fits with other information on the same topic. Letters to the editor provide a
way for readers of the medical journal to express comments ,questions or
criticisms about articles published in that
journal.
