　　Stem Cell Therapy May Help Repair the Heart
　　According to scientists in the USA，stem cell therapy may one day be able to repair the hearts of people with heart failure．Researchers at Pittsburgh University School of Medicine examined 20 patients who had severe heart failure and were going to have surgery．
　　They injected stem cells into the parts of their hearts that were damaged，They then compared their hearts with those of people who had undergone surgery without having the stem cells injected into them(they had also suffered from severe heart failure)．The patients who had had the stem cells injected had hearts that were able to pump(用泵抽运)more blood than the others．
　　According to Professor Robert Kormos，one of t11e researchers，these results could revolutionize heart treatment．Although previous studies had indicated that there might be a benefit，this is the first study that has actually proved that stem cell therapy can help the failing heart work better．
　　All the patients in this study had hearts that could not pump blood properly．The scientists measured their ejection fraction(射血分数)．1t is a measure of heart performance；you measure how much blood is being pumped out by the left ventricle(心室).
　　Healthy people's ejection fraction is about 55％．These patients had ejection fraction of under 35％．They a11 had by-pass surgery(搭桥手术)performed on them．Some of the patients had stem cells taken from their hip bones and injected into 25-30 sites in the damaged heart muscle，Six months later their ejection fraction rate was 46．1％while those who just had surgery but no stem cell injections averaged 37 2％．
　　No side effects were reposed．
　　Heart failure is a common problem all over the world．In the UK alone about 650,000 people suffer from heart failure every year．As the number of people suffering from heart failure increases in the world in general these findings are particularly significant．
　　Current treatments relieve the symptoms．This new stem cell therapy actually repairs the damaged muscle in the heart and has the potential of curing the disease．
　　16 The 20 patients had stem cell injections instead of surgery．
　　A Right
　　B Wrong
　　C Not mentioned
　　17 The experiment proved to be satisfactory．
　　A Right
　　B Wrong
　　C Not mentioned
　　18 The control group patients regretted not having had stem cell injections．
　　A Right
　　B Wrong
　　C Not mentioned
　　19 The study actually proved for the first time the benefit of stem cell therapy
　　A Right
　　B Wrong
　　C Not mentioned
　　20 The ejection fraction rate of the patients with stem cell injections decreased．
　　A Right
　　B Wrong
　　C Not mentioned
　　21 Heart failure is more common in the UK than anywhere else in the world．
　　A Right
　　B Wrong
　　C Not mentioned
　　22 Stem cell therapy seems to have great prospects．
　　A Right
　　B Wrong
　　C Not mentioned

　　The Drink Your Body Needs Most
　　1 Our bodies are estimated to be about 60％to 70％water．Blood is mostly water．and our muscles，lungs，and brain all contain a lot of water．Water is needed to regulate body temperature and to provide the means for nutrients (滋养物)to travel to all oar organs．Water also transports oxygen to our cells，removes waste，and protects our joints and organs．
　　2 we lose water through urination(排尿)，respiration(呼吸)，and by sweating．If you are very active，you lose more water than if you do not take much exercise．Symptoms of mild dehydration(脱水)include chronic pains in joints and muscles，lower back pain，headaches，and constipation(便秘)．A strong smell to your urine，along with a yellow color indicates that you are not getting enough water．Thirst is an obvious sign of dehydration and in fact，you need water long before you feel thirsty．
　　3 A good rule of thumb(好旳做法)is to take your body weight in pounds and divide that number in half．That gives you the number of ounces(盎司)of water per day that you need．For example．if you weigh 160 pounds，you should drink at least 80 ounces of water per day．If you exercise you should drink another 8-ounce glass of water for every 20 minutes you are active．If you drink coffee or alcohol，you should add at least an equal amount of water．When you are traveling on an airplane，it is good to have 8 ounces of water for every hour you are on board the plane．
　　4 It may be difficult to drink enough water on a busy day．Be sure you have water handy at all times by keeping a bottle for water with you when you are working，traveling，or exercising．If you get bored with plain water,add a bit of lemon for a touch of flavor．There are some brands of flavored water available，but some of them have sugar or artificial sweeteners that you 1dQn》，need

　　Diabetes(糖屎病)and Eye Damage
　　0vet 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'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't available or doesn'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(模糊旳)vision，black spots or flashing lights．As time goes on，it Can progress to blindness Everyone with diabetes is at risk for diabetic retinopathy，and the risk increases the longer you'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 d0 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 36 Glucose cannot be turned into energy in the body
