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 the 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).This 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 all 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 reported.
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.

The control group patients regretted not having had stem cell injections.

Napping to a Healthier Heart?
1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.
2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP.Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.
3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.
4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heart disease patient should affect that person's treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in the Journal of the American Medical Association.
5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelated study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children.But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in the United States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take naps.
6 The researchers say napping may improve heart health by reducing stress.They say the research suggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.

According to some researchers,by measuring the levels of NT-proBNP in the blood people may know______.
A:where fewer people die from heart problem
B:whether they have the risk of heart attack,heart failure or stroke
C:would probably have lower rates of heart disease
D:how to test a person's NT-proBNP level in the blood by himself
E:his heart muscle would be under pressure in some way
F:that napping is of great benefit to women too

答案:B
解析:
第二段主要介绍了加利福尼亚大学一个团队所进行的研究。通过检查心脏病人的NT-proBNP水平,发现水平最高的病人与水平最低的病人之间患心脏病的可能性相差近8倍。
第三段说到,研究涉及的多是男性,并发现年老且患有糖尿病或高血压者NT-proBNP的水平最高。
由第四段的内容可知,其他研究者认为还要确认一些问题,如心脏病病人的蛋白质水平是否影响其治疗;他们还想知道更多的积极治疗能否减少病人得心脏病或中风的机会。
第五段说到,地中海国家的成年人普遍都午睡,而且患心脏病的几率较低。哈佛大学和雅典大学的研究证明,每周午睡三次,每次30分钟的人比完全不午睡的人死于心脏病的几率低37%。
由第一段最后两句可知,研究人员检测血液中蛋白质的水平,他们称血液中这种蛋白质水平高的人得心脏病或中风的几率高,故选B。
由第三段第一句可知,血液中含有高浓度的该种蛋白质证明心肌受到了压迫。

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 the 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).This 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 all 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 reported.
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.

Stem cell therapy seems to have great prospects.
