Organ Donation and Transplantation

1 Organ donation（捐献）and transplantation（移植）refers to the process by which organs or tissues
from one person are put into another person's body.
2 The number of people needing a transplant continues to rise faster than the number of donors.About
3,700 transplant candidates are added to the national waiting list each month.Each day,about 77 people
receive organ transplants.However,18 people die each day waiting for transplants that can't take place
because of the shortage of donated organs.
3 There are rio age limits on who can donate.Newborns as well as senior citizens have been organ
donors. If you are under age 18 , you must have a parent's or guardian's consent（同意）.If you are 18 years or
older,you can show you want to be an organ and tissue donor by signing a donor card.
4 Many people think that if they agree to donate their organs,the doctor or the emergency room staff
won't work as hard to save their life.This is not true.The transplant team is completely separate from the
medical staff working to save your life.The transplant team does not become involved with you until doctors
have determined that all possible efforts to save your life have failed.
5 If you need an organ transplant,your doctor will help you get on the national waiting list.Your name
will be added to a pool of names.When an organ donor becomes available,all the patients in the pool are
compared to that donor. Factors such as blood and tissue type, size of the organ, medical urgency（紧急）of
the patient's illness , time already spent on the waiting list, and distance between donor and recipient（接受
者）are considered.

Text4 Death comes to all,but some are more sure of its timing,and can make plans.Kate Granger,a 32-year-old doctor suffering from an incurable form of sarcoma,has"very strong ambitions"for her last hours.She plans to avoid hospital emergency departments and die at her parents'house-music playing,candles glowing,family by her side.Surveys show that over two-thirds of Britons would like to die at home.Like Dr.Granger,they want to be with family and free ofpain.Yet hospital remains the most common place ofdeath.For some this is unavoidable-not every disease has as clear a tuming point as cancer-but for others a lack of planning is to blame.The govemment,motivated by both compassion and thrift,wants to help.To steer patients away from hospitals,general practitioners have been encouraged to find their l%-those patients likely to die in the next year-and start talking about end-of-life care.This can be difficult for doctors."As a profession we view death as failure,"says Dr.Granger.Yet when there is no cure to be had,planning for death can be therapeutic for patients.Those who do plan ahead are much more likely to have their wishes met.A growing number of patients have electronic"palliative-care co-ordination systems",which allow doctors to register personal preferences so that other care providers can follow them.A paramedic called to a patient's home would know of a do-not-resuscitate order,for example.One study showed that such systems increase the number of people dying in their homes.But savings for the government may mean costs for charities and ordinary folk.At the end of life it is not always clear who should pay for what.Although Britons can get ordinary health care without paying out of pocket,social care is means-tested.People must often shell out for carers or care homes-or look after the terminally ill themselves.Disputes crop up over trivial things,like responsibility for the cost ofa patient's bath.A bill now would cap the cost of an individual's social care by Parliament.Still,some want it to be free for those on end-of-life registries.That would cut into the govemment's savings-but allow more people to die as they want.38.The"palliative-care co-ordination systems"may suggest

A.doctors require patients to receive treatment at home.
B.patients can get different advice from several doctors.
C.incurable patients could choose to stay at home.
D.part ofthe patients are unwilling to waste money in hospital.

Promising Resnlts from Cancer Study
A new experimental vaccine（疫苗）has shown promising results in the fight against lung cancer.In a small Texas-based study,a vaccine developed by scientists at Baylor University Medical Centre in Dallas,USA,cured lung cancer in some patients and slowed the progress of the disease in others.
Researchers have reported encouraging findings from this small study.Forty一three patients suffering from lung cancer were involved in these trials.Ten of these patients were in the early stages and thirty-three in tho advanced stages of the disease.They were injected with the vaccine every two weeks for three months,and were carefully monitored for three years.In three of the patients in the advanced stages of cancer,the disease disappeared and in the others,it did not spread for five to twenty-four months.However,no great difference was seen in the patients in the early stages of the illness.
This new vaccine uses the patient's own immune system.It is made specifically for each patient and is injected into the arm or leg.It stimulates（刺激）the body's immune system, which then recognizes that the cancer cells are harmful,and attacks and destroys them.
The vaccine could be effective against other forms of cancer.It offers great hope for the treatment of cancer in general,although further studies are needed before such treatment can be widely used.

The vaccine activates the immune system.

Double Effect
The Supreme Court's decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering.
Although it ruled that there is no constitutional right to physician-assisted suicide,the Court in effect supported the medical principle of"double effect",a centuries-old moral principle holding that an action having two effects-a good one that is intended and a harmful one that is foreseen-is permissible if the actor intends only the good effect.
Doctors have used that principle in recent years to justify using high doses of morphine to control terminally ill patients'pain,even though increasing dosages will eventually kill the patient.
Nancy Dubler,director of Montefiore Medical Center,contends that the principle will shield doctors who"until now have very,very strongly insisted that they could not give patients sufficient mediation to control their pain if that might hasten death."
George Annas,chair of the health law department at Boston Univeisity,maintains that,as long as a doctor prescribes a drug for a legitimale medical purpose,the doctor has done nothing illegal even if the patient uses the drug to hasten death."It's like surgery,"he says."We don't call those deaths homicides because the doctors didn't intend to kill their patients,although they risked their death.if you're a physician,you can risk your patient's suicide as long as you don't intend their suicide."
On another level,many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying.
Just three weeks before the Court's ruling on physician一assisted suicide,the National Academy of Science(NAS)released a two-volume report,Approaching Death:Improving Care at the End of Life.It identifies the under-treatment of pain and the aggressive use of"ineffectual and forced medical procedures that may prolong and even dishonor the period of dying" as the twin problems of end-of-life care.The profession is taking steps to require young doctors to train in hospices,to test knowledge of aggressive pain management therapies,to develop a Medicare billing code for hospital-based care,and to develop new standards for assessing and treating pain at the end of life.
Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care."Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering,"to the extent that it constitutes"systematic patient abuse." He says medical licensing boards"must make it clear that painful deaths are presumptively ones that are incompetently managed and should result in license suspension."

George Annas would probably agree that doctors should be punished if they______.
A:manage their patients incompetently
B:give patients more medicine than needed
C:reduce drug dosages for their patients
D:prolong the needless suffering of the patients

Which of the following statements is true according to the text?

Text l How,when and where death happens has changed over the past century.As late as 1990 half of deaths worldwide were caused by chronic diseases;in 2015 the share was two-thirds.Most deaths in rich countries follow years of uneven deterioration.Roughly two-thirds happen in a hospital or nursing home.They often come after a ctimax of desperate treatment.Such passionate intervention can be agonising for all concerned.These medicalised deaths do not seem to be what people want.Polls find that most people in good health hope that,when the time comes,they will die at home.They want to die free from pain,at peace,and surrounded by loved ones for whom they are not a burden.But some deaths are unavoidably miserable.Not everyone will be in a condition to toast death's imminence with champagne,as Anton Chekhov did.What people say they will want while they are well may change as the end nears.Dying at home is less appealing if all the medical kit is at the hospital.A treatment that is unbearable in the imagination can seem like the lesser of two evils when the alternative is death.Some patients will want to fight until all hope is lost.But too often patients receive drastic treatment in spite of their dying wishes~by default,when doctors do"everything possible",as they have been trained to,without talking through people's preferences or ensuring that the prediction is clearly understood.The legalisation of doctor-assisted dying has been called for,so that mentally fit,terminally ill patients can be helped to end their lives if that is their wish.But the right to die is just one part of better care at the end of life.The evidence suggests that most people want this option,but that few would,in the end,choose to exercise it.To give people the death they say they want,medicine should take some simple steps.More palliative care is needed.Providing it earlier in the course of advanced cancer alongside the usual treatments turns out not only to reduce suffering,but to prolong life,too.Most doctors enter medicine to help people delay death,not to talk about its inevitability.But talk they must.Medicare,America's public health scheme for the over-65s,has recently started paying doctors for in-depth conversations with terminally ill patients;other national health-care systems,and insurers,should follow.Cost is not an obstacle,since informed,engaged patients will be less likely to want pointless procedures.Fewer doctors may be sued,as poor communication is a common theme in malpractice claims.
We can learn from Paragraph 3 that____

A.dying patients suffer undertreatment
B.doctor-paiient communication is poor
C.doctor-assisted dying has been legalized
D.the right to die is better cure for dying patients

The Supreme Court's decisions on physician-assisted suicide carry important implications for how medi-
cine seeks to relieve dying patients of pain and suffering.
Although it ruled that there is no constitutional right to physician-assisted suicide,the Court in effect
supported the medical principle of"double effect",a centuries-old moral principle holding that an action
having two effects一a good one that is intended and a harmful one that is foreseen一is permissible if the actor
intends only the good effect.
Doctors have used that principle in recent years to justify using high doses of morphine to control termi-
nally ill patients' pain,even though increasing dosages will eventually kill the patient.
Nancy Dubler,director of Montefiore Medical Center,contends that the principle will shield doctors
who"until now have very,very strongly insisted that they could not give patients sufficient mediation to con-
trol their pain if that might hasten death."
George Annas,chair of the health law department at Boston University,maintains that,as long as a
doctor prescribes a drug for a legitimate medical purpose,the doctor has done nothing illegal even if the pa-
tient uses the drug to hasten death."It's like surgery,"he says."We don't call those deaths homicides be-
cause the doctors didn't intend to kill their patients,although they risked their death.If you're a physician,
you can risk your patient's suicide as long as you don't intend their suicide."

Hypertension Drugs Found to Cut Risk of Stroke

Australian doctors declared Monday that a cocktail of simple antihypertensive drugs can lower the risk of
patients suffering a repeat stroke by more than a third.This is the result of their research.The research,
presented at a medical conference in Italy over the weekend,has been valued highly as a major breakthrough
in stroke prevention.
Strokes kill 5 million people a year,and more than 15 million suffer non-fatal strokes that often leave
them with useless limbs,slurred speech and other serious disabilities.One in five stroke survivors goes on to
have a second,often fatal,stroke within five years of the first.
An international six-year study of 6,100 patients directed from Sydney University found that by taking
two blood pressure-lowering drugs,the risk of secondary strokes can be reduced by up to 40 percent.Even
taking one of the commonly available drugs can cut the risk by a third,the study said.The drugs are the diu-
retic indapamide( 吲达帕胺）and the ACE inhibitor perindopril , better known by its brand name Coversyl.
The combination was effective even in patients who did not have high blood pressure,the researchers said.
They even found that the risk of another stroke could be cut by three quarters among the one-in-ten patients
who had suffered a cerebral hemorrhage（出血）, the worst type of stroke , where there is direct bleeding into
the brain.
Stephen McMahon,who presented the research at the Milan congress of the European Society of
Hypertension,said about 50 million people were alive who had suffered at least one stroke."If most of those
patients were able to get access to this treatment,it would result in maybe the avoidance of haff a million
strokes a year,"the professor told Australia's ABC Radio.
McMahon said doctors had long known that lowering the blood pressure of those with hypertension could
help prevent strokes."What we have shown for the first time is that it does not really matter what your blood
pressure is;if you have had a stroke,then lowering blood pressure will produce large benefits,to begin
with一even for people whose blood pressure is average or below average,"he said.
McMahon said the Milan gathering had heralded the research as a"major breakthrough in the care of
patients with strokes一perhaps the biggest step forward that we have made in the last couple of decades."

Taking two blood pressure-lowering drugs may produce________less risk of secondary stroke than taking only one such drug.
A:three quarters
B:nearly four tenths
C:one fifth
D:about one fourteenth
