Exercise Can Replace Insulin （胰岛素） for Elderly Diabeties （糖尿病）

Most 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 Berlingske 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 utilize insulin by 30 per cent， the newspaper reported.

This is equal tol 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 utilize as a measure for how well their insulin worked.

Associate Professor Dr. Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilization as the healthy non-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 realize that they have to watch their diet while remaining unaware of the importance of exercise， Dela added.

How could most elderly type II diabetics stop taking insulin？查看材料

A.By taking more salt than usual.

B.By taking less salt than usual.

C.By doing brisk exercise for half an hour at least three times a week.

D.By going climbing， swimming or boxing every day.

根据下面材料，回答题。

Diabetes (糖尿病) and Eye Damage

Over 2 million Canadians have diabetes. It is the leading cause of blindness in North Americans under 65 years of age. Diabetes is a condition where the body either cannot produce enough insulin (胰岛素) or cannot respond properly to insulin. Insulin is important because it moves glucose (葡萄糖), a simple sugar, into the body&39;s cells from the blood. The food people eat provides the body with glucose, which is used by the cells as a source of energy. If insulin isn&39;t available or doesn&39;t work correctly to move glucose from the blood into the cells, glucose will stay in the blood, leading to high blood sugar levels.

High blood sugar levels damage the blood vessels, including the tiny blood vessels in the eye. This leads to an eye disease known as diabetic retinopathy (糖尿病型视网膜病). The retina (视网膜) is an area at the back of the eye that changes light into nerve signals, With diabetic retinopathy, some blood vessels in the retina are lost, and some of the other blood vessels begin to "leak" blood. This causes the retina to swell and gradually cuts off its supply of oxygen and nutrients (滋养物). Eventually, the retina starts to grow new blood vessels to replace the damaged ones. Unfortunately, these new vessels are not as strong as the old ones. They are more likely to break, causing bleeding in the eye.

At first, people with diabetic retinopathy will not notice any symptoms. As the disease gets worse, they may notice blurred (模糊的) vision, black spots or flashing lights. As time goes on, it can progress to blindness.

Everyone with diabetes is at risk for diabetic retinopathy, andthe risk increases the longer you&39;ve had diabetes.

Fortunately, you can reduce your risk if you do not have diabetes, but think you may be at risk for this condition. Visit your doctor to be screened for diabetes. If you do have diabetes: have frequent eye check-ups.

Make sure that you monitor your blood sugar frequently and use your medications as

recommended by your doctor. There is evidence to show that keeping your blood sugar under tight control can slow down eye damage. If you have high blood pressure, follow your recommended diet and medications to keep it under control. If you are not sure whether you have high blood pressure, or whether your blood pressure is under control, discuss this with your doctor.

Glucose cannot be turned into energy in the body__________. 查看材料

A.without diabetes

B.without sugar

C.without insulin

根据以下内容回答题：

Christopher Thomas，27，was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast．Diagnosed with diabetes，Thomas would need to inject himself with insulin(胰岛素)three times a day for the rest of his life or risk nerve dam-age，blindness and even death．And if that weren’t bad enough，he had no heMth insurance．

After a month of feeling upset，Thomas decided he’d better find a way to fight back．He left Canton，Michigan for New York，got a job waiting tables，nicknamed himself the Diabetic Rockstar，and created diabeticrockstar．com，a free online community for diabetics and their loved ones——a place where over l．100 people share information and resources．

Jason Swencki’s son，Kody，was diagnosed with diabetes at six．Father and son visit the online children’s forums(论坛)together most evenings．“Kbdy gets so excited．writing to ki出from all over，”says Swencki，one of the site’s volunteers．“They know what he’s going through．so he doesn’t feel alone．”

Kody is anything but alone：Diabetes is now the seventh leading cause of death in the United States，with 24 million diagnosed cases．And more people are being diagnosed at youn-ger ages．

These days，Thomas’s main focus is his charity(慈善机构)，Fight It，which provides medicine and supplies to people--225 to date—who can’t afford a diagnostic large expenses．Fight-it．org has raised about$23，000一in products and in cash．In Mav．Thomas will hold the first annual Diabetic Rockstar Festival in the Cafibbean．

Even with a staff of 22 volunteers，Thomas often devotes up to50 hours a week to his cause，while still doing his full time job waiting tables．“of the diabetes charities out there．most are putting money into finding a cure，”says Bentliey Gubar，one of Rockstar's original member．“But Christopher is the only person I know saying people need help now．”

Which of the follow．ing is true of Christopher Thomas？查看材料

A.He needs to go to the doctor every day．

B.He sdudies the leading cause of diabetes．

C.He has positive attitude to his disease．

D.He encourages diabetics by writing articles．

Slowing Aging: Way to Fight Diseases in 21st Century

A group of aging experts from the United States and the United Kingdom suggest that the best strategy for preventing and fighting a multitude of diseases is to focus on slowing the biological processes of aging.

"The traditional medical approach of attacking individual diseases- cancer， diabetes， heart disease， Alzheimer"s disease （早老性痴呆病） and Parkinson"s disease （帕金森氏病） –will soon become less effective if we do not determine how all of these diseases either interact or share common mechanisms with aging，" says S. Jay Olshansky， professor of epidemiology at the University of Illinois at Chicago School of Public Health and senior author of the commentary.

Middle-aged and older people are most often impacted by simultaneous but independent medical conditions. A cure for any of the major fatal diseases would have only a marginal impact on life expectancy （预期寿命） and the length of healthy life， Olshansky said.

The authors suggest that a new paradigm （模式） of health promotion and disease prevention could produce unprecedented social， economic and health dividends for current and future generations if the aging population is provided with extended years of healthy life.

They note that all living things， including humans， possess biochemical mechanisms that influence how quickly we age and， through dietary （饮食的） intervention or genetic alteration， it is possible to extend lifespan to postpone aging-related processes and diseases.

Further research in laboratory models is expected to provide clues to and deeper understanding of how existing interventions， such as exercise and good nutrition， may lead to life-long well-being.

The authors also propose greatly increased funding for basic research into the "fundamental cellular （细胞的） and physiological changes that drive aging itself".

"We believe that the potential benefits of slowing aghag processes have been underrecognized by most of the scientific community，" said Olshansky. "We call on the health research decision-makers to allocate substantial resources to support and develop practical interventions that slow aging in people."

An increase in age-related diseases and escalating health care costs make this the time for a"systematic attack on aging itself"， the authors write.

Olshansky and colleagues contend that modem medicine is already heavily invested in efforts to extend life， and they argue that a fresh emphasis on aging has the potential to improve health and quality of life far more efficiently than is currently possible.

The experts believe the traditional approach of attacking individual diseases __________. 查看材料

A.is the best strategy for fighting diseases

B.focuses on slowing aging processes

C.has gone out of date

D.needs to be improved
