共用题干Clinical Trials1. Many clinical trials are done to see if a new drug or device is safe and effective for people to use.Sometimes clinical trials are used to study different ways to use the standard treatments so they will be more effective,easier to use,and/or decrease side effects.Sometimes,studies are done to learn how to best use the treatment in a different population,such as children,in whom the treatment was not previously tested.2. It is important to test drugs and medical products in the people they are meant to help.It is also important to conduct research in a variety of people because different people may respond differently to treatments.Some people participate in clinical trials because they have exhausted standard treatment options .Other people participate in trials because they want to contribute to the ad-vancement of medical knowledge.3. The FDA（食品及药物管理局）works to protect participants in clinical trials and to ensure that people have reliable information as they decide whether to join a clinical trial.Although efforts are made to control the risks to clinical trial participants,some risks may be unavoidable because of the uncertainty inherent（内在的）in medical research studies involving new medical treatments.4. People should learn as much as possible about the clinical trials that interest them.They should also feel comfortable discussing their questions and concerns with members of the health care team. Prospective（预期的）participants should understand what happens during the trial ,the type of health care they will receive,and any costs to them.Anyone considering a clinical trial should also know that there are benefits and risks associated with participating. Paragraph 2______A: Are clinical trials safe?B: What are clinical trials?C: What should people know before participating in a clinical trial?D: Who should consider clinical trials and why?E: Where are clinical trials conducted?F: Why are clinical trials done?
共用题干Exercise can Replace Insulin for Elderly DiabeticsMost older people with so-called type Ⅱ diabetes could stop taking insulin if they would do brisk exercise for 30 minutes just three times a week,according to new medical research results reported in the Copenhagen newspaper Berlin gske Tidende on Monday.Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet's Center for Muscle Research showed that physical exercise can boost the body's ability to utilise insulin by 30 percent,the newspaper reported.This is equal to the effect most elderly diabetics get from their insulin medication today, it said.Researchers had a group of non-diabetic men and a group of men with type Ⅱ,all more than 60 years of age,exercise on bicycles six times a week for three months.After the three months the doctors measured how much sugar the test subjects'muscles could utilise as a measure for how well their insulin worked.Associate Professor Dr. Hemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilisation as the healthy non一exercising persons.“This means that the insulin works just as well for both groups.Physical exercise cannot cure people of diabetes,but it can eliminate almost all their symptoms. At the same time it can put off the point at which they have to begin taking insulin or perhaps completely avoid insulin treatment,”Dela was quoted as saying.Insulin is a hormone produced by the pancreas,controlling sugar in the body and used against diabetes.Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to work up a sweat,but that the activity has to be maintained since it wears off after five days without sufficient exercise.Most diabetics realise that they have to watch their diet while remaining unaware of the importance of exercise,Dela added.The subjects of the research tests conducted at the Copenhagen Central Hospital included______.A: elderly non-diabetic menB: elderly type Ⅱ diabetic menC: both sexes of all agesD: both A and B
