单选题 Everyone arriving at a hospital's emergency room (ER) wishes to be seen quickly, but for stroke patients it can be a matter of life or death. The most common stroke involves a blood clot blocking vessels in the brain, killing brain cells nearby almost immediately. Luckily, an effective treatment exists. Thrombolytic therapy uses drugs to dissolve the clot and restore the flow of blood. If started within a couple of hours of a stroke occurring, it can limit brain damage and reduce long-term disability. Neurologists even have a catchphrase for this: 'time is brain'. Understandably, hospitals strive to identify stroke cases and administer such medication without delay. A key step is using a computed tomography (CT) scanner to ensure that there has been no bleeding in the brain, in which case thrombolytic drugs would make things worse. The last couple of decades have seen many innovations in reducing this 'time to CT'. But in shaving seconds from medical procedures, researchers may have neglected something more important: the human element. Gal Ifergane, a neurologist at Soroka University Medical Centre in southern Israel, noticed that stroke patients who were accompanied to the ER by Mends or family seemed to fare better than those who arrived alone. So for 15 months, ER staff at Soroka recorded the number of companions escorting each stroke sufferer, over 700 in all, and tracked their progress. The results, recently published in Medicine, tell a striking story. Stroke victims arriving with someone were more than twice as likely to be correctly diagnosed by the triage nurse, and had their CT scans performed earlier. Patients eligible for clot-busting medication also received it much faster if accompanied, although their numbers were too few for the researchers to be sure it was because they had company. The differences were far from trivial. Patients with one companion had CT scans an average of 15 minutes sooner than those unaccompanied. A second companion shaved a farther 20 minutes off the wait, although three or more companions did not confer any additional benefit. Dr. Ifergane did not record who the companions were, however, or how they were able to reduce delays. He believes that it is probably a combination of focusing the attention of clinical staff on their loved ones, and providing basic care such as helping to move patients into bed. Dr. Ifergane admits that his study has limitations. The sample size was rather small and his findings may reflect cultural norms in Israel that do not apply elsewhere. But he has already tried to make changes in the way the Soroka University Medical Centre operates. 'We asked our security team to allow two people to come in with stroke patients rather than just one,' he says. 'And we now consider stroke patients who are coming alone as a group at risk.' Dr. Ifergane also recommends that ERs provide a friendly 'stroke liaison' to accompany lone patients during the diagnostic and treatment processes. Something other hospitals might think about, too.

单选题He ______ his head, wondering how to solve the problem.

单选题A library is more than just a place where books are stored. A library is a source of information. That information may come from books (fiction, nonfiction, or reference books), from periodicals (newspapers, magazines, and journals), from audio-visual materials (records, cassettes, microfilm, video tapes, etc.), or even from a computer terminal. Students go to libraries to study and to write research papers. The periodicals room of a university library is where foreign students often find newspapers and magazines from their countries. In the reference room, they can find catalogs from many universities in the U.S. and other countries. If you are buying a used car, the reference librarian can show you the Blue Book, which lists the prices of new and used cars. People who need information in a hurry can telephone the reference librarian at many libraries. There are as many different library services as there are types of people who use them. Children"s libraries provide materials for young readers. They sometimes have story tellers who read stories to groups of children, and a few have computers for the children to play with. Music lovers can listen to recordings of their favorite musicians in music libraries. Some libraries, offer special services for blind people, such as books in Braille, "talking" books, and Kurzweil Reading Machines. Libraries provide entertainment as well as information. Novels and short stories from a library"s fiction collection are a good source of enjoyable reading practice. Public libraries often sponsor lectures on topics of interest to members of the community, and a few even offer concerts and films. No matter what your interests are, you will find that a library can be a great place to enjoy yourself while you learn.

单选题Richard Satava, program manager for advanced medical technologies, has been a driving force bringing virtual reality to medicine, where computers create a "virtual" or simulated environment for surgeons and others medical Practitioners (从业者). "With virtual reality we'll be able to put a surgeon in every trench," said Satava. He envisaged a time when soldiers who are wounded fighting overseas are put in mobile surgical units equipped with computers. The computers would transmit images of the soldiers to surgeons back in the U. S. The surgeons would look at the soldier through virtual reality helmets (头盔) that contain a small screen displaying the image of the wound. The doctors would guide robotic instruments in the battlefield mobile surgical unit that operate on the soldier. Although Satava's vision may be years away from standard operating procedure, scientists are progressing toward virtual reality surgery. Engineers at an international organization in California are developing a tele-operating device. As surgeons watch a three-dimensional image of the surgery, they move instruments that are connected to a computer, which passes their movements to robotic instruments that perform the surgery. The computer provides feedback to the surgeon on force, textures, and sound. These technological wonders may not yet be part of the community hospital setting but increasingly some of the machinery is finding its way into civilian medicine. At Wayne State University Medical School, surgeon Lucia Zamorano takes images of the brain from computerized scans and uses a computer program to produce a 3-D image. She can then maneuver the 3-D image on the computer screen to map the shortest, least invasive surgical path to the tumor (肿瘤). Zamorano is also using technology that attaches a probe to surgical instruments so that she can track their positions. While cutting away a tumor deep in the brain, she watches the movement of her surgical tools in a computer graphics image of the patient's brain taken before surgery. During these procedures—operations that are done through small cuts in the body in which a miniature camera and surgical tools are maneuvered—surgeons are wearing 3-D glasses for a better view. And they are commanding robot surgeons to cut away tissue more accurately than human surgeons can. Satava says, "We are in the midst of a fundamental change in the field of medicine. /
