1 . Many people fear a visit to the dentist. They are not so much afraid of the doctor, but of the dental equipment and treatments. For over a century, dentists have been repairing the bad tooth in the same way. They first remove the bad tooth tissue with an electric-powered drill. Then, they fill the hole with a certain material. If the hole is deep and near the nerve of the tooth, it can be very painful. The worst part is that the process of drilling and filling the hole has to be repeated for the entire life of that tooth.
A British company called Reminova says it has developed a kind of technology that will end the need for mechanical cleaning of bad teeth. It also says the technology speeds up a natural process of tooth repair. The new treatment begins with a cleaning of the hole. This does not require power tools. The dentist covers the problem area with a mineral solution, and then uses an electrical current to harden this material. The electricity is too weak for the patient to feel. And the hardened mineral completely fills the hole.
Researchers say this method could be especially useful for children. Sometimes children have bad experiences at the dentist’. They fear the drilling and injections. If they have a better experience of going to the dentist’, they’ll be much more positive in later life and probably become much more regular patients. The new method is most efficient on the early-stage bad tooth. The whole treatment lasts about as long as a normal drill-and-fill visit. They believe the new technology can be further developed for treating the late-stage bad tooth.

2 . One of the important, but seldom-discussed, problems in healthcare reform is how to take care of our aging population as people continue to live longer. According to a new study from the MacArthur Research Network on an Aging Society, by 2050 Americans may live 3.1 to 7. 9 years longer than the government expects. That would mean women would live 89 to 93 years and men 83 to nearly 86 years. The researchers base their conclusion on "rapid advances in biomedical（生物医药）technology that delay the start and progression of major deadly diseases or that slow the aging process・”
While this is good news, especially for the young, the life expectancy, which is in excess of（超过）the government's estimates, would raise costs sharply for Medicare and Social Security. If the study's predictions are accurate, the total cost for those two programs through 2050 could be between $ 3. 2 trillion and $ & 3 trillion higher than the US Census Bureau（人口普查局）and the Social Security Administration currently expect.
And that's only the beginning. With anticipated scientific breakthroughs in coming decades, people could eventually live to 150 years of age, says Dr. Steven Joyal, an official of the Life Extension Foundation (LEF) a nonprofit organization that promotes research on how we can live longer and healthier. The MacArthur paper, in fact, says that some experts believe the average life expectancy could hit 100 by 2060.
What's more, Joyal says, the conquest（战胜）of disease and the slowing of the aging process will lead to a sharp decline in disability, allowing people of advanced age to function as well as they did when they were much younger. "In other words, a 90-year-old person could have the same mental and physical capacity as somebody 40 or 50 years old."

3 . People have different ways of dealing with a common cold. Some take over the counter medicines such as aspirin while others try popular home remedies(治疗) like herbal tea or chicken soup. Yet here is the tough truth about the common cold: nothing really cures it.
So why do people sometimes believe that their remedies work? According to James Taylor, professor at the University of Washington, colds usually go away on their own in about a week, improving a little each day after symptoms peak, so it's easy to believe it's medicine rather than time that deserves the credit, USA Today reported.
It still seems hard to believe that we can deal with more serious diseases yet are powerless against something so common as a cold. Recently, scientists came closer to figure out why. To understand it, you first need to know how antiviral drugs work. They attack the virus by attaching to and changing the surface structures of the virus. To do that, the drug must fit and lock into the virus like the right piece of a jigsaw(拼图), which means scientists have to identify the virus and build a 3D model to study its surface before they can design an antiviral drug that is effective enough.
The two cold viruses that scientists had long known about were rhinovirus(鼻病毒) A and B. But they didn't find out about the existence of a third virus, rhinovirus C, until 2006. All three of them contribute to the common cold, but drugs that work well against rhinovirus A and B have little effect when used against rhinovirus C.
''This explains most of the previous failures of drug trials against rhinoviruses,'' study leader Professor Ann C. Palmenberg at the University of Wiscons in Madison, US, told Science Daily.
Now, more than 10 years after the discovery of rhinovirus C, scientists have finally built a highly detailed 3D model of the virus, showing that the surface of the virus is, as expected, different from that of other cold viruses.
With the model in hand, hopefully a real cure for a common cold is on its way. Soon, we may no longer have to waste our money on medicines that don't really work.

5 . Sam is a fourth-year student at Harvard Medical School，but poetry is still a big part of his life，now with a new teacher，Rafael Campo，who believes poetry can benefit every doctor’s education and work. Rafael is a physician，professor and a highly respected poet.
“Poetry is in every encounter(邂逅)with my patients. I think healing is really in a very great way about poetry. And if we do anything when we’re with our patients，we’re really immersing(使沉浸于)ourselves in their stories，really hearing their voices. And，certainly，that’s what a poem does，”he said.
Rafael worries that something important has been lost in medicine and medical education today：humanity，which he finds in poetry. To end that，he leads a weekly reading and writing workshop for medical students and residents(住院医生).
He thinks medical training focuses too much on distancing the doctor from his or her patients，and poems can help close that gap.
Third-year resident Andrea Schwartz was one of the workshop regulars. She said. “I think there’s no other profession other than medicine that produces as many writers as it does. And I think that is because there’s just so much power in doctors and patients interacting when patients are at their saddest. ”Not everyone believes that’s what doctors should do，though.
Rafael said，“I was afraid of how people might judge me，actually. In the medical profession，as many people know，we must always put the emergency first. But，you know，that kind of treatment，if it’s happening in the hospital，very regrettably，sadly，results in a bad outcome. The family is sitting by the bedside. The patient hasn’t survived the cancer. Don’t we still have a role as healers there?”
In a poem titled“Health”，Rafael writes of the wish to live forever in a world made painless by our incurable joy. He says he will continue teaching students，helping patients and writing poems，his own brand of medicine.

6 . Over a four-year period, Swiss researchers have developed a machine that can keep human livers (肝)alive outside of the body for one week.
Livers are among the most commonly transplanted (移植)human organs. Current technology can only keep human livers alive for up to 24 hours. It is reported that, in 2017, about 8.000 liver transplants were performed in the U.S., of which 360 used livers from living givers In addition, about 11,500 people were registered on a waiting list to receive a liver transplant. Keeping livers alive and functioning for longer periods could greatly improve the chances of survival for patients.
The researchers say the purpose of their “Liver4Life” machine is to perform what they call liver perfusion (灌注)operations outside of the human body. Perfusion is the process by which blood or other liquids are pumped through organs and tissue. The machine keeps the liver at the right temperature and moves it in a way that would be natural in the body. Using a pump to fill the liver with blood acting like a human heart, the machine also provides oxygen to the organ, controls red blood cell levels and removes waste.
The research team began their experiments with livers from pigs. After repeated testing and engineering development, they succeeded in getting the pig livers to survive for seven days with support only provided from the Liver4Life machine. They also discovered the system can work to repair damaged livers. The team is now planning its next step to transplant machine-treated organs into patients.
Pierre-Alain Clavien. leader of the research said in a statement. “This technology will greatly increase the number of livers available for transplant, improving the chances of survival for patients. The success of this unique machine opens the way for many new applications in transplantation and cancer medicine.”

The inclusion of TCM in the ICD is a mainstream acceptance that will have significant influence around the world. TCM has seen some growth in other countries for all these years. It is reported
8 . Each year there are at least five million people around the world who develop serious flu (流感), and almost half a million deaths. When someone we know gets the flu virus, we expect them to be very careful not to pass it on to others. Doctors and nurses working with flu patients also need to protect themselves from the virus. But what is the best way to do this? This is the question that flu expert Professor Jonathan
Van-Tam at Nottingham University is trying to answer. He wants to find out how flu is transmitted, so that he can stop doctors and nurses getting sick.
Van-Tam explains their method, "There are 41 volunteers in my experiment. Some healthy volunteers are made to get flu first. When they show symptoms (症状 ) , other volunteers, usually called recipients(接受者), enter the house. Everyone lives together in the small space for four days. Some of the recipients wear face masks, and wash their hands every 15 minutes, but some have no protection. In this way we can study who catches the flu and which ways of transmitting flu are important. During the four days when they are in contact with the virus, and for the ten days after that, the flu recipients are checked regularly."
The experiment is not simple and it is very expensive. It is difficult to design correctly, and it is also difficult to plan and carry out. Just one study like this takes about 18 months to organize and needs hundreds of people working on it. But Van-Tam believes it is worth because the results will help to decide what type of protection is needed for people working in hospitals with large numbers of flu patients around the world. And perhaps it could reduce the number of deaths from flu each year.

9 . It is not easy to become a doctor in the United States. The first step is getting into a medical college. More than one hundred and twenty American schools offer study programs for people wanting to be doctors.
People can get advice about medical schools from many resources. One of these is the Princeton Review. The publication provides information about colleges, study programs and jobs.
The Princeton Review says the competition to enter medical schools is strong. American medical schools have only about sixteen thousand of openings. But more than thirty-two thousand students may try it. Many of those are women.
Most applicants contact more than one medical school. Some contact many. An important part of the application usually is the Medical College Admission Test which is called MCAT. The Association of American Medical Colleges provides the test by computer. It is offered in the United States and other countries.
The people who want to enter medical schools are rated（评定）on reasoning, physical and biological sciences and an example of writing. Applicants for medical schools need to do well on the MCAT. They also need a good record in their college studies.
Some students work for a year or two in a medical or research job before they attempt to enter a medical school.

10 . It has been around for centuries, but up until very recently, traditional Chinese medicine (TCM) wasn’t fully accepted abroad. Proof of this can be found in The Treatment (《刮痧》), a 2001 film that tells the story of a Chinese man in the US who’s accused of abuse after he uses guasha, a form of TCM treatment, to cure his grandson’s disease.
During the last 10 years or so, however, TCM has been getting increasingly popular all over the world. A report released by the State Council Information Office on Dec. 6 says this style of health care, which includes different forms like herbal medicine and exercise, has spread to 183 countries and regions.
“We have set up 10 TCM centers outside China, and all of them are popular among locals,” Wang Guoqiang, head of the State Administration of Traditional Chinese Medicine, said at a news conference on Dec 6. “Governments of 86 countries and regions have signed agreements with the Chinese government on TCM corporation.”
One of the reasons behind the growing popularity of TCM is the increase of scientific research into it. And after Tu Youyou, the Chinese scientist who discovered the anti-malaria (抗疟疾) drug qinghaosu (青蒿素), won the Nobel Prize in 2015, TCM became even more famous internationally.
However, all these achievements in TCM don’t mean that it’s problem-free. Over the years, TCM has faced challenges in being able to prove that it has certain effects.
Some researchers have suggested TCM should be more exact and work together with Western medicine.
“Bringing together with Western medicine and TCM, rather than being in competition, is where the potential for great effects is,” said Bernhard Schwartlander, the China representative of the World Health Organization.
