1 . Natural therapy (疗法)
The great outdoors: it's the place to head for when you're in need of peace and quiet, open spaces, beautiful scenery and exercise. Whether a huge mountain range or a local country park, these natural areas are perfect places to refresh us when we live a stressful life.
As an example, in the foothills of the Snowdonia National Park in the UK, specialist therapy sessions are held to help people who suffer from depression, anxiety and stress.
It is true that for most of us, connecting with the natural world definitely lifts our spirits. But the mental health charity Mind says eco-therapy has been recognized as a formal type of treatment that can sometimes be recommended to someone by a doctor. It doesn't involve medicine.
There is evidence that there are many benefits with this "green" therapy.
| A．Of course, eco-therapy won't cure everything. |
| B．Outdoor art-related activities are held for the participants. |
| C．Instead, it just develops a person's relationship with nature. |
| D．Here you can learn from other patients how to deal with stress. |
| E．These include improving social contact, social and work skills. |
| F．In nature you can do many things, including reading papers and watching TV. |
| G．Their calming and relieving power is being used more and more to treat mental health problems. |
2 . Adults with a poor education are also likely to have poor health, a growing body of evidence suggests. Study after study has confirmed the link, and now experts are zeroing in on the reasons for it and what can be done. “Persons with a higher education tend to have better jobs, and better income, better benefits,” said David R. Williams, a professor of public health in America.
Those benefits, he said, go beyond health benefits to include such other factors as having the flexibility to take a day off or part of a day to see a doctor. “People with higher levels of education tend to have more resources to cope with stress and life,” Williams said. They have stress, of course, but also more resources to cope with it — such as access to a health club to exercise away the stress — than people with less education, he said.
“Being better educated also means that a person is more likely to understand the world of modern medicine,” said Erik Angner, an assistant professor of philosophy and economics at the University of Alabama at Birmingham, who has researched the link between education and happiness. “Modem medicine is incredibly complex. And if you lack the basic reading skills required to function adequately in the health-care environment, you might find it harder to effectively understand your medical care.”
A report issued by Williams’ commission found that, compared with college graduates, adults who did not graduate from high school were 2.5 times as likely to be less than very good health. The report suggested that factors outside the medical system play an important role in determining people’s health. Access to medical care is crucial, but it isn’t enough to improve health. What’s needed, they suggested, is increased focus on schools and education — encouraging people to obtain more education.

5 . In the winter of 1910, Dr. Wu Lien-teh stepped off a train in the northern Chinese city of Harbin. He was there to solve a medical mystery, at great personal risk. Over the past few months, an unknown disease had swept along the railways of northeast China, killing 99.9%of its victims. The Qing Imperial court had sent the Cambridge-educated Dr. Wu north to stop the epidemic (流行病).
When Dr Wu arrived in Harbin on Christmas Eve, 1910, he carried little in the way of medical instruments and had only one assistant. One of Wu’s first acts upon arrival was to set up special quarantine (隔离) units and to order lockdowns to stop infected persons from traveling and spreading the disease. He had teams check households for possible cases, and even managed to convince authorities to completely close the railways in the early weeks of 1911. Of particular concern was the upcoming Chinese New Year holiday, which had become a great annual migration of people traveling across the country to see their families.
Thanks to Dr. Wu’s efforts, the number of victims began to die down, and by March 1, 1911, the epidemic was fully contained. The pneumonic plague outbreak of 1910-1911 lasted nearly four months, affected five provinces and six major cities, and accounted for over 60,000 deaths. It is clear that without the brave and decisive actions taken by Dr. Wu, it could have been much worse. Had the epidemic gone unchecked, allowing holiday rail passengers to spread the disease to the rest of China could have meant a catastrophic loss of life and possibly a global health crisis.
In April 1911, Dr. Wu chaired an International Plague Conference in Shenyang, attended by scientists from 11 counties including the United States, Great Britain, Russia, Japan and France. They praised Dr. Wu for his handling of the 1910-1911 outbreak. For a time, Dr. Wu was the world’s most famous plague fighter, a title be defended in a malaria epidemic in China in 1919, and a return of plague in 1921.

6 . Every day, it seems that some new algorithm (算法) enables computers to diagnose a disease with unprecedented accuracy, renewing predictions that computer's will soon replace doctors. What if computers could replace patients as well? If virtual humans could have replaced real people in some stages of a coronavirus vaccine trial, it could have sped development of a preventive tool and slowed down the pandemic. Similarly, potential vaccines that weren't likely to work could have been identified early, reducing trial costs and avoiding testing poor vaccine candidates on living volunteers. These are some of the benefits of “in silico medicine”, or the testing of drugs and treatments on virtual organs or body systems to predict how a real person will respond to the therapies.
The modeling begins by feeding anatomical data drawn from noninvasive (非侵入式) high- resolution imaging of an individual's actual organ into a complex mathematical model of the mechanisms that govern that organ's function. Algorithms running on powerful computers resolve the resulting equations and unknowns, generating a virtual organ that looks and behaves like the real thing.
In silico clinical trials are already underway to an extent. Heart Flow Analysis, for instance, enables clinicians to identify CAD (冠心病) based on CT images of a patient's heart. The Heart Flow system uses these images to construct a fluid dynamic model of the blood running through the coronary blood vessels, thereby identifying abnormal conditions and their severity. Without this technology, doctors would need to perform an invasive operation to decide whether and how to intervene. Experimenting on digital models of individual patients can also help personalize therapy for any number of conditions and is already used in diabetes care.
The philosophy behind in silico medicine is not new. The ability to create and simulate the performance of an object under hundreds of operating conditions has been a cornerstone of engineering for decades, such as for designing electronic circuits, airplanes and buildings. Various obstacles remain to its widespread implementation in medical research and development.
The predictive power and reliability of this technology must be confirmed, and that will require several advances. Those include the generation of high quality medical databases from a large, ethnically diverse patient base that has both women and men; improvement of mathematical models to account for the many interacting processes in the body; and further modification of Al methods that were developed mainly for computer-based speech and image recognition and need to be extended to provide biological insights.
In recent years American and European regulators have approved some commercial uses of computer-based diagnostics, but meeting regulatory demands requires considerable time and money. Creating demand for these computer-based diagnostic tools is challenging as well. In silico medicine must be able to deliver cost-effective value for patients, clinicians and health care organizations to accelerate their adoption of the technology.

8 . The Art of Healing
If no further evidence available of the sophistication of China in the Tang Dynasty, then a look at Chinese medicine would be sufficient. At the western end of the Eurasian continent, the Roman empire disappeared, and there was nowhere new to claim the important position of the cultural and political centre of the world. In fact, for a few centuries, the centre happened to be the capital of the Tang Empire, which boasted its national health service, and Chinese medicine under the Tang was far ahead of European medicine. The organizational context of health and healing was structured to a degree that had never happened in China before and found a similar one nowhere else.
An Imperial Medical Office had been inherited from previous dynasties: it was immediately restructured and staffed with directors, chief and assistant medical directors, pharmacists and managers of medicinal herb gardens. Within the first two decades after enforcing its rule, the Tang administration set up one central and several provincial medical colleges to train students in one or all of the departments of medicine, acupuncture (针灸) and physical therapy. Physicians were given positions in governmental medical service only after passing qualifying exams. They were paid according to the number of cures they had effected during the past year.
In 723, Emperor Xuanzong personally composed a formulary of prescriptions（方剂集）recommended to him by an imperial pharmacist and sent it to all the provincial medical schools. An Arabic traveller, who visited China in 851, noted with surprise that prescriptions from the emperor’s formulary were posted on notice boards at crossroads to enhance the welfare of the population.
The government protected people from potentially harmful medical practice. The Tang legal code was the first in China to include laws concerned with harmful medical practice. For example, to treat patients for money without following standard procedures was defined as deceiving combined with theft and had to be tried as theft. If such therapies resulted in death of a patient, the healer was to be sent to a remote place for years. In case a physician purposely failed to practice according to the standards, he was to be tried as murdering. Even if no harm resulted, he was to be punished.

9 . Israeli researchers say they have created the world's first three-dimensional, or 3D-printed heart using a patient's own cells. They described the experiment as "a major medical breakthrough." Tal Dvir, the lead researcher on the project, said in a statement that it was the first time that human cells had been used with 3D printing technology to successfully create a whole heart. Dvir added that the "printed" heart contains blood vessels which are needed to pump blood. The development marks a step forward for 3D printing in the medical field.
The researchers took samples of fatty tissue from patients. This material was then used to develop “ink” for the 3D printing process. First, the researchers created patches of tissue from the patient’s own cells. Later, they used that same process to create a small version of a whole heart. Using the patient’s own cells is important to reduce the risk that the body’s system to fight infection will reject a transplanted organ.
The goal, the researchers said, is to treat heart disease. The World Health Organization reports that heart disease is by far the leading cause of death worldwide. For patients with severe heart disease, a heart transplant is currently the main treatment available. The researchers hope their invention can help ease the demand for heart transplant donors.
Dvir says that the newly-created heart represents great progress. However, more research and development is needed to produce a fully operating, transplantable organ. One of the biggest challenges for the engineering team will be finding a way to create a human-sized heart.
Dvir said his team planned to transplant heart models designed for animals, possibly within the next year. He added that, for human use, “simpler organs” will likely be produced before hearts. “Maybe, in ten years, there will be organ printers in the finest hospitals around the world,” Dvir said. He hopes such methods will be used “routinely” to produce organs in the future.

10 . A medical capsule robot is a small, often pill-sized device that can do planned movement inside the body after being swallowed or surgically inserted. Most models use wireless electronics or magnets or a combination of the two to control the movement of the capsule. Such devices have been equipped with cameras to allow observation and diagnosis, with sensors that “feel,” and even with mechanical needles that administer drugs.
But in practice, Biomechatronics engineer Pietro Valdastri has found that developing capsule models from scratch (从头开始) is costly, time-consuming and requires advanced skills. “The problem was we had to do them from scratch every time,” said Valdastri in an interview. “And other research groups were redeveloping those same modules from scratch, which didn’t make sense.”
Since most of the capsules have the same parts of components: a microprocessor, communication submodules, an energy source, sensors, and actuators (致动器), Valdastri and his team made the modular platform in which the pieces work in concert and can be interchanged with ease. They also developed a flexible board on which the component parts are snapped in like Legos. The board can be folded to fit the body of the capsule, down to about 14 mm. Additionally, they compiled (编译) a library of components that designers could choose from, enabling hundreds of different combinations. They arranged it all in a free online system. Designers can take the available designs or adapt them to their specific needs.
“Instead of redeveloping all the modules from scratch, people with limited technological experience can use our modules to build their own capsule robots in clinical use and focus on their innovation,” Valdastri said.
Now, the team has designed a capsule equipped with a surgical clip to stop internal bleeding. Researchers at Scotland’s Royal Infirmary of Edinburg have also expressed interest in using the system to make a crawling capsule that takes images of the colon(结肠). One research group, led by professors at the Institute of Digestive Disease of the Chinese University of HongKong, is making a swimming capsule equipped with a camera that pushes itself through the stomach.
One limitation of Valdastri’s system is that it’s only for designing models. Researchers can confirm their hypotheses (假设) and do first design using the platform, but will need to move to a custom approach to develop their capsules further and make them practical for clinical use.
