1 . People in Australia have been really cautious about using natural or alternative treatments compared to other places, according to Dr. Paul Laver, a professor at the University of Sydney. He thinks this is because doctors in Australia have always been very powerful, and they are unwilling to let others take their place. In many other countries, regular treatments and these alternative treatments have worked closely together for a long time. For example, in Germany, medicines made from plants account for 10%of the country’s medicine sales. In the United States, more people visited these alternative therapists (治疗专家) than regular doctors in 1990.
During the past 20 years, more people in Australia have started to like these alternative treatments. In a 1983 national health survey, 1.9% of people say they had contacted alternative therapists like chiropractors or herbalists. By 1990, this figure had risen to 2.6% of the population. Rather than criticizing this trend, increasing numbers of doctors in Australia, especially the younger ones, are starting to work with alternative therapists or take courses themselves, particularly in acupuncture and herbalism. Part of the motivation was financial, Dr Laver said. The bottom line is that most doctors don’t want to lose patients. If they see potential patients going elsewhere, they might want to be able to offer a similar service.
In 1993, Dr. Laver did a survey in Sydney and found that people who went to alternative health therapists were usually those who hadn’t been helped much by regular medicine. These people liked the holistic approach of their alternative therapists, and the friendly, concerned and detailed attention they had received, which they didn’t always get from regular doctors.
The survey suggested that people visited alternative therapists for various problems like muscle pains, stomach issues, and emotional stress etc. It suggested that calling it “complementary medicine” might be better because people use it alongside regular medicine, d especially when regular medicine doesn’t seem to help.

2 . Occasionally, doctors become patients too. While I wouldn’t wish ill-health on anyone, it can be an inspiring lesson for medical professionals to suddenly be on the other side.
This happened to me a few months ago when I had a kidney stone, which had decided to make its unwelcome presence known in a rather romantic fashion just as I was going out for dinner. The pain came from absolutely nowhere but within minutes I was incapacitated. I was quite taken aback by how astonishingly painful it was.
As a doctor, I initially refused to believe that anything was seriously wrong, because I have witnessed countless individuals come to the emergency room convinced they are dying only for nothing more than trapped wind and then creep (蹑手蹑脚) out as they burp (打嗝) loudly and the pain disappears. However, the unbearable pain continued to exist, forcing me to acknowledge that this was indeed more than just a stubborn burp,
I was particularly pleased to read afterwards in a medical textbook that renal colic, as the pain is known, is the “most painful event a person can endure, often described as being worse than childbirth”. It’s no wonder chronic (慢性的) pain drives people mad. While doctors talk about pain and its management, it’s hard to put into words how exhausting it really is until you’ve experienced it for yourself.
During my time in hospital, I interacted with numerous doctors, each exhibiting professionalism and kindness but one stuck out in my mind. He was actually the most junior of them all, but something about his manner was incredibly calming and comforting. Whenever he came to my bed to speak to me, he knelt down so he was at my eye level. This simple act rid me of the stress that other healthcare professionals unintentionally projected. Just kneeling down made all the difference.
Experiencing the role reversal of doctor-turned-patient provided me with profound insights into the realities of pain and effective patient care.

3 . Medical artificial intelligence (AI) can perform with expert-level accuracy and deliver cost-effective care. IBM’s Watson diagnoses (诊断) heart disease better than cardiologists (心脏病专家) do. Chatbots give better medical advice to patients in place of nurses. Some forecast that medical AI will enter 90% of hospitals and replace as much as 80% of what doctors currently do. Yet, as our recent research suggests, patients show a strong resistance to medical AI.
The reason, we found, is not the belief that AI provides lower care. Nor is it that patients think that AI is more costly or less informative. Rather, resistance to medical AI seems to come from a belief that AI does not take into account one’s specific circumstances. People view themselves as unique. By contrast, they think medical care delivered by AI providers is suited to treat an average patient but unsuitable to account for the unique circumstances that apply to an individual. No wonder that medical AI providers are given a cold welcome.
There are a number of steps that care providers can take to overcome patients’ resistance to medical AI. For example, if an AI provider is capable of tailoring its recommendation for whether to have a surgery to each patient’s unique characteristics and medical history, patients would be likely to follow the treatment recommendations of the AI provider. In addition, health care providers could also deliver individualized health care by explaining how the algorithms (算法) work and sharing patients’ reviews with the media. Having a physician confirm the recommendation of an AI provider should make people more willing to accept AI-based care. People are comfortable using medical AI if a physician remains in charge of the ultimate decision.
AI-based health care technologies are being developed and employed at an impressive rate, providing better medical services for the patients. But harnessing the full potential of them will require that we first overcome patients’ doubt of having an algorithm, rather than a person making decisions about their care.

4 . A new medicine developed in China has been recently introduced, which is expected to significantly enhance the prevention and control of malaria in Africa. Compared with the previous medicines, this latest medicine is not only more efficient but also easier to administer. Its introduction is anticipated to result in a sharp decline in the number of deaths caused by malaria.
In case studies conducted in Kenya, second-generation artesunate(青蒿琥酯) for injection, developed by Chinese medicine company Fosun Pharma, has proved highly effective in treating severe malaria in children, Kenyan health experts said.
In addition, the new drug—produced under the brand name Argesun—can be easier and faster to prepare, and safer to inject, than its previous generation, which was produced under the name Artesun, and which was widely used in dozens of countries for more than10 years.
“We think that this is a very good development. It is really going to cut our rate of deaths and also the complications caused by malaria,” Walter Otieno said, a Kenyan Medical researcher.
Argesun was pre-qualified by the World Health Organization in June and has been registered in 18 African countries, according to Fosun Pharma.
Both Artesun and Argesun are innovative antimalarial drugs based on artemisinin (青蒿素), which was discovered by Nobel Prize winner Tu Youyou in the 1970s,and which has made significant contributions to malaria control and prevention in the world during the past two decades.
Wu Yifang, chairman of Fosun Pharma, said the company recognized the strategic value of antimalarial drugs based on artemisinin and restructured its sub company Guilin Pharmaceutical in 2004 to start introducing the drugs to the international market. Its first antimalarial drug entered Africa in 2007,and the company launched a training program for front-line medical workers in Africa in 2014.
“To win the battle against malaria, we have to get rid of it worldwide,” Wu said, adding that the company is pushing to transform its antimalarial drugs from “made in China and used in Africa” to “made in Africa and used in Africa”, in order to increase the accessibility and affordability of the drugs there.

5 . Healthy human skin is covered with bacteria (细菌) that are quick to settle in an open wound. To prevent these organisms from spreading through the body, which can permanently injure or kill a person, the infected wound may need to be cleaned and treated with antibiotics. Medical professionals typically identify infections by unwrapping and observing a wound or by swabbing (用拭子擦拭) it and conducting a laboratory test. But removing a wound dressing can slow down the healing process. Plus, observations are subjective, while swab tests take time and require that a patient be physically present.
To address these issues, some research teams are developing devices that sit under bandages and continuously monitor indirect signs of infection, such as changes in wound temperature or acidity. And scientists at the National University of Singapore have now created an even more direct infection sensor.
This sensor can detect an enzyme (酶) called DNase. The enzyme acts as a reliable infection indicator because disease-causing bacteria produce it in large amounts inside wounds, whereas bacteria on healthy skin do not—so testing for the substance reduces the chance of a false positive result. Furthermore, DNase builds up before other infection signs appear. The new alert system, nicknamed the“wireless infection detection on wounds” (WINDOW) sensor, was detailed in Science Advances.
WINDOWs enzyme-sensing parts rely on a material called DNAgel. There searchers developed a particular kind of DNAgel that remains stable in watery environments, such as the human body, but begins to break down in the presence of DNase. They connected this gel (凝胶) to a chip that senses when the gel responds by sending a signal to a smartphone.
Thus far, the team has exposed the DNAgel to wound swabs from 18 people’s wounds to see how much the material degraded in the presence of the bacteria. There searchers also used the device on six living lab mice whose wounds were exposed to the same bacterial species, and it successfully detected infections.

6 . Wisdom teeth won’t make you smarter.
Wisdom teeth often cause problems due to their late eruption and limited space in jaws. As a result, they may become impacted, meaning they are unable to fully emerge from the gums (牙龈). This impaction can give rise to various issues, including pain and crowding of nearby teeth.
Before the surgery, dentists will carefully evaluate your specific situation to determine the most appropriate approach. During the procedure, dentists will numb (麻醉) your gum to ensure minimal pain.
Here are some tips for proper healing. Leave cotton in place for about 30 minutes and hold a cold pack against your jaw to reduce pain immediately after surgery. For the following days, don’t consume hard spicy food like nuts and peppers.
A.How long does the surgery usually last? |
B.Stick to soft food or liquid diets instead. |
C.Mild saltwater is good for mouth wounds. |
D.What happens after wisdom teeth removal? |
E.They will then use tools to loosen the tooth and pull it out. |
F.They’re called that because they usually come in when you get older. |
G.To prevent or address these problems, many dentists decide on wisdom teeth removal. |
7 . Brynn Schulte nearly died two times when she was a baby. At one point she needed emergency surgery for bleeding in her brain. No one knew what was wrong. Then, a test that looked at her full genetic details found a rare bleeding disorder. Catching the disorder early saved her life. “You have this hopeless feeling when you don’t really know what’s going on,” said her father, Mike Schulte. He noted that the test made a difference in finding the cause and “getting her the right care that she needed almost immediately”.
Brynn, now 4, got the genetic testing as part of a clinical trial, the results of which were published recently in The Journal of the American Medical Association. Testing all of the details of a person’s genes is called “whole genome” testing. Whole genome tests are much better than narrowly targeted tests when it comes to finding genetic differences, called abnormalities, which can cause disease. The study found 49 percent of these abnormalities, compared to 27 percent with more commonly used tests targeting only some genetic diseases.
Whole genome tests could solve the problem of doing several narrowly targeted tests on babies, which still might not find the disorder. Experts warn there are some problems because labs vary in how they understand results. Also, whole genome tests are more expensive and less likely to be covered by insurance.
But researchers hope that whole genome tests will at some point be used for millions of hospitalized babies with rare and difficult conditions. The US National Human Genome Research Institute has found that around 350 million people around the world live with rare disorders. And it found that about 80 percent of the more than 7,000 conditions are genetic.

8 . Desperately ill and seeking a miracle, David Bennett Sr. took the last bet on Jan. 7. when be became the first human to be successfully transplanted with the heart of a pig. “It creates the beat; it creates the pressure; it is his heart,” declared Bartley Griffith, director of the surgical team that performed the operation at the University of Maryland Medical Center.
Bennett, 57, held on through 60 tomorrows, far longer than any previous patient who’d received a heart from another species. His remarkable run offered new hope that such procedures, known as xenotransplantation (异种移植), could help relieve the shortage of replacement organs, saving thousands of lives each year.
The earliest attempts at xenotransplantation of organs, involving kidneys from rabbits, goats, and other animals, occurred in the early 20th century, decades before the first successful human-to-human transplants. Rejection, which occurs when the recipient’s body system recognizes the donor organ as a foreign object and attacks it, followed within hours or days. Results improved after some special drugs arrived in the 1960s, but most recipients still died after a few weeks. The record for a heart xenotransplant was set in 1983, when an infant named Baby Fae survived for 20 days with an organ from a baboon (狒狒).
In recent years, however, advances in gene editing have opened a new possibility: re-edit some genes in animals to provide user-friendly spare parts. Pigs could be ideal for this purpose, because they’re easy to raise and reach adult human size in months. Some biotech companies. including Revivicor, are investing heavily in the field. The donor pig was offered by Revivicor from a line of animals in which 10 genes had been re-edited to improve the heart’s condition. Beyond that, the pig was raised in isolation and tested regularly for viruses that could infect humans or damage the organ itself.
This medical breakthrough provided an alternative for the 20% of patients on the heart transplant waiting list who die while waiting or become too sick to be a good candidate.
1. What does the underlined word “run” in paragraph 2 refer to?A.Donating his heart to a patient. |

9 . When Philip Santini noticed an infection, he contacted his primary care physician, Jane Chargot, M. D., and she gave him some medicine.
However, test results showed that he wasn’t recovering. Over the phone, Santini was told he would need to go to the hospital to get infusions (输液) three times a day for a week. He was packed and ready to head out to the hospital when he received another phone call. An alternative plan was suggested instead — Hospital Care at Home.
Care at Home, a Michigan Medicine program which improves the patient experience while freeing up hospital beds, has already admitted and transferred more than 50 patients from the emergency department and inpatient hospital to receive hospital level care from the comfort of their own homes.
Santini was the first direct registration patient for this program, meaning he never presented to the hospital initially. It was no surprise that there was a celebration for this milestone.
“I was ready to head out to the emergency department,” said Santini, who even had a list of things to take when he got a call from Stephanie Paran, R. N., a nurse at U-M Briarwood Family Medicine. “Hearing Paran’s words, I sprang to my feet and didn’t hesitate to accept the advice.”
Although he initially didn’t know what to expect, he later said what the care team did was far beyond his expectations, especially the caregivers. The staff gave him infusions three times a day for six days. They took his regular medications away, just like how they would in a hospital. They checked the infection, drew blood and even brought in an ultrasound machine. “I didn’t know that was possible,” Santini said. After discharge, a Michigan Visiting Nurse visited once a week until he completely recovered.
Santini believed treatment at home has helped the healing process. “I’ve never felt really comfortable in the hospital,” he said. “It’s hard to get good sleep there. At home I had my own food, my own bed, plus my wife is here. No one has to go out of their way to visit me. It’s a healthier experience. I would encourage anyone to consider it.”
1. What is the advantage of Care at Home?A.It can reduce the patients’ expenses. |
B.It can lessen the pressure on hospitals. |

10 . Imagine a future where science has created your twin. Not a flesh-and-blood twin, but one that recreates your flesh and blood, your bones, your heart, your brain — your whole body, in fact — as an extremely complicated computer model.
Your doctors can use this digital twin to work out how you will respond to a particular drug or medical procedure. They can even look further into the future, creating a “healthcast”, to forecast what diseases might happen to you or how your lifestyle will affect your health as you age. It is the ultimate in personalized medicine. This is the bold vision set out in Virtual You: How building your digital twin will revolutionize medicine and change your life by Peter Coveney, director of the Centre for Computational Science, and Roger Highfield, science director of the Science Museum Group, UK.
Digital twins are already in widespread use in industries such as civil engineering. But these model systems are much simpler than the complex human body. Imagine all the parts that come together to make you work: from the 3 billion letters of your genome (基因组), the numerous molecules (分子) that make up your cells, the trillions of cells building your tissues and organs, and the environment having its input too. Now, imagine trying to create a model of this that is made to each unique individual and that predicts the changes that will take place over a lifetime. This is easier said than done. Changes in the systems biologists want to describe are usually different from what mathematicians describe as “non-linear” (非线性的). Another complication is “emergence”: where the whole of a system is greater than the sum of its parts. This complexity challenges mathematics and pushes computing to the limit too.
But getting to the next level — a whole human individual — is going to require yet more data and a revolution in computing technology far beyond what is currently possible. Whether we will get there is an open question, but Virtual You shows us what scientists from different fields can achieve when they all work together.
