1 . PRACTITIONERS

Jacqueline Felice de Almania (c.1322) highlights the suspicion that women practicing medicine faced. Born to a Jewish family in Florence, she moved to Paris where she worked as a physician and performed surgery. In 1322 she was tried for practicing unlawfully. In spite of the court hearing testimonials (证明) of her ability as a doctor, she was banned from medicine.	James Barry (c.1789 — 1865) was born Margaret Bulkley in Ireland but, dressed as a man, she was accepted by Edinburgh University to study medicine. She qualified as a surgeon in 1813, then joined the British Army, serving overseas. Barry retired in 1859, having practiced her entire medical profession living and working as a man.
Tan Yunxian (1461 — 1554) was a Chinese physician who learned her skills from her grandparents. Chinese women at the time could not serve apprenticeships (学徒期) with doctors. However, Tan passed the official exam. Tan treated women from all walks of life. In 1511, Tan wrote a book, Sayings of a Female Doctor, describing her life as a physician.	Rebecca Lee Crumpler (1831 — 1895) worked as a nurse for eight years before studying in medical college in Boston in 1860. Four years later, she was the first African American woman to receive a medical degree. She moved to Virginia in 1865, where she provided medical care to freed slaves.

Did you ever imagine that one day we could enjoy the benefits of Traditional Chinese Medicine in a cup of coffee?

Traditional Chinese Medicine, or TCM, is    1    approach used to help people re-balance their health and mind. A typical way of making a TCM formula (配方) is to get a prescription from a    2    (license) doctor, shop for all the medicinal materials, and then brew(煎) them with water in a pot. These materials    3    (say) to have a restorative effect by re-balancing one’s natural energy, or Qi,     4    runs through series of invisible meridians (经脉) throughout the body.

But if you ask younger generations of Chinese, few visit TCM shops nowadays, let alone brew these time-tested remedies for    5    (they). However, social media has recently seen a type of coffee    6    (feature) goji berry juice get popular.

The concept of combining TCM herbs    7    popular drinks could make young people access TCM more easily. The key of TCM is    8    (prevent). By trying such drinks, young people can take more care of their health, and nip sicknesses in the bud. Most people, attracted in such a cafe by the”new TCM drinks“ at first, would also be offered other TCM products like dried herbs and teas, after which they stay    9    (learn) more about TCM.

As Traditional Chinese Medicine becomes more    10    (access) to young people, many are integrating these ancient drinks into their daily wellness routines.

Traditional Chinese medicine (TCM) is a health care system in which patients     1     (treat) with natural plant, animal, and mineral remedies (药物). It is assumed, for a person to be healthy,     2     yin and yang forces should he in balance. Imbalance causes illness or injury. TCM is about     3     (restore) the balance between yin and yang forces in patients. It has been a major part of traditional Chinese culture and continues to play     4     vital role in medical treatment in China today.

According to the World Health Organization, nearly 80 percent of the world's population depends for its primary health care needs    5     medicines from plants and animals. This is especially true in countries where traditional medicines are     6     (wide) used.

Increasingly, however, modern medicines also contain substances from animals and plants. Given growing populations, increasing wealth, and the spreading    7     (popular) of natural remedies around the world, the demand for these medicines and remedies     8     (rise) now. The rising demand,     9     (combine) with reduced habitat, has caused an alarming increase in the number of plant and animal species used for medicinal purposes at risk for many years. For instance, TCM uses about 1,000 plant and 36 animal species, including the tiger, rhinoceros, and sea horse,     10     are all in danger.

5 . On January 7, David Bennett went into the operating room at the University of Maryland Medical Center for a surgical procedure never performed before on a human. The 57-year-old Maryland resident had been hospitalized for months due to a life threatening disease. His heart was failing him and he needed a new one.

Bennett’s condition left him unresponsive to treatment and ineligible (不合格) for the transplant list or an artificial heart pump. The physician-scientists at the center, however, had another-also risky- option: transplant (移植) a heart from a genetically-modified pig.

“It was either die or do this transplant,” Bennett had told surgeons a day before the operation. “I want to live. I know it’s a shot in the dark, but it’s also my last choice.”

It took the medical team eight hours to finish the operation, making Bennett the first human to successfully receive a pig’s heart. “It’s working and it looks normal. We are thrilled, but we don’t know what tomorrow will bring us. This has never been done before,” Barkley Griffith, who led the transplant team, told the New York Times.

While it’s only been five days since the operation, the surgeons say that Bennett’s new pig heart was, so far, functioning as expected and his body wasn’t rejecting (排斥) the organ. They are still monitoring his condition closely.

“I think it’s extremely exciting,” says Robert Montgomery, transplant surgeon and director of the NYU Langone Transplant Institute, who was not involved in Bennett’s operation. The result of the procedure was also personally meaningful for Montgomery, who received a heart transplant in 2018 due to a genetic disease that may also affect members of his family in the future. “It’s still in the early days, but still the heart seems to be functioning. And that in and of itself is an extraordinary thing. Up to now most experimental heart transplant procedures have been done between pigs and other animals. This is the first time that surgeons have taken it into a living human.”

Incense (香) boasts a long history,    1    its roots in many cultures-ancient China, ancient Egypt, Babylon and beyond. People from all walks of life benefit from its countless qualities, whether they use it for pleasure    2    as medicine.

Since the Tang and Song dynasties, burning incense, hanging paintings, making tea, and enjoying music have been known as the “four arts for literati (文人)”.    3    (make) from seeds, leaves and flowers, incense has been used as an enjoyable     4    (pursue) for scholars.

Moreover, medical incense is an essential part of Traditional Chinese Medicine, which considers preventative healthcare as     5    far superior form of treatment when illness strikes.

    6    (basic), medical incense can kill bacteria in the environment, protecting people against infections. It is also believed     7    (possess) the ability to balance the flow of Qi, a vital energy force within the body. Once the medical elements within incense are breathed in, they soon find    8    (they) way into the bloodstream. From there they go directly to the organs    9    treatment assistance is needed. The specific types of incense    10    (choose) based on the individual’s condition, aiming to restore balance and promote well-being.

7 . Researchers say a new electrical device placed in three paralyzed patients has helped them walk again. The lower bodies of the three patients were left paralyzed after they suffered spinal (脊柱的) cord injuries. But a device implanted in the spinal cord was able to send electrical signals to the muscles to permit them to stand, walk and exercise.

Scientists have discovered that neurons—which receive and send signals for muscle movements—often still work in injured patients with serious spinal cord injuries. However, past research into spinal cord injuries has centered on the stimulation of neurons. Now in the latest experiment led by Gregoire Courtine and Jocelyne Bloch of the Swiss Federal Institute of Technology in Lausanne, three paralyzed men were implanted a new electrical device designed to copy an action of the brain, in which it sends signals to the spinal cord that result in muscle movement. When the spinal cord receives the brain signals, it stimulates a collection of nerve cells that can activate different muscles.

The researchers reported that all three patients who got the spinal cord implants were able to take their first steps within an hour after receiving them. Over the next six months, the patients regained the ability to take part in more advanced walking activities, the study found. They were also able to ride bicycles and swim in community settings.

Unlike other attempts to help paralyzed patients walk by stimulating nerves through the back of the spine, Courtine said that his team redesigned the devices so signals would enter the spine from the sides. This method permits more direct targeting and activation of spinal cord areas, he said.

The team then developed artificial intelligence (AI) systems linked to the device. The AI controls electrodes on the device to send signals to stimulate individual nerves that control muscles needed for walking and other activities. However, because the patients’ muscles were weak from not being used, they needed help with supporting their weight, the researchers said. It also took some time for them to learn to work with the technology. Still, Bloch said, “The more they train, the more they start lifting their muscles, the more fluid it becomes.”

Traditional Chinese Medicine (TCM) originated in ancient China. It     1    (include) acupuncture (针灸), Chinese herbal medicine, tai chi, qigong, tuina, guasha, cupping and so on.

Acupuncture was one of the first TCM       2    (method) that were accepted by the healthcare system in the USA. It was first introduced to the USA in 1971 by a New York Times reporter, James Reston, in an article     3    (title) “Now, about my operation in Peking”.

In 1997. acupuncture was     4    (official) accepted by the National Institutes of Health of the US, and in a statement in 2002, the World Health Organization recognized acupuncture as an     5    (effect) treatment for more than 43 common ailments (小病). TCM focuses     6     not only the disease treatment, but also the disease prevention and     7    (improve) of overall health.

Today, TCM is primarily used as an alternative for people     8    (maintain) a healthy state in the US. It is widely practiced in more than 180 countries and regions around the globe; among them, 103 countries have approved     9     use of acupuncture, 29 have established some forms of laws and regulations for TCM, 18 have included acupuncture into their national health insurance systems,     10     more than 30 have colleges and universities that teach students in TCM.

9 . Metin Sitti at the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, and his colleagues have developed tiny robots called “microrollers” that can carry cancer drugs and selectively target human breast cancer cells. The team drew inspiration for the design of the robots from white blood cells in the human body, which can move along the walls of blood vessels (血管) against the direction of blood flow.

The microrollers are round and made from glass microparticles. One half of the robot was coated with a thin magnetic nanofilm (磁性纳米膜) made from nickel and gold. The other half was coated with the cancer drug doxorubicin as well as molecules that recognize cancer cells.

The team tested the robots using mouse blood and artificial channels lined with human endothelial cells—the kind of cells that line the inner walls of our blood vessels. The robots were exposed to a mixture of cancerous and healthy tissue. The microrollers selectively attached to the cancer cells and were activated using UV light to release the doxorubicin.

By applying magnetic fields, the team was able to control the movement of the microrollers, both with and against the flow of blood. The microrollers can reach a speed of up to 600 micrometers per second. “If you come to a spot where you need to take the right path and if you miss it, then you could go back and go to the right one,” says Setti.

In future, the researchers want to use other methods to start the drug release, such as heat or near-infrared light. They also plan to try making microrollers out of materials that would break down in the body over a few weeks or months.

The team hopes to test the microrollers in animals soon. “The rollers need to carry enough cancer drugs, which is why we need to have them in large numbers,” says Setti. “But since we can locally take drugs to the right target, we don’t need huge dosages (剂量).”
