2 . Nearly two years after the COVID-19 outbreak, China has granted approval to its first antibody combination treatment for COVID-19.
A team from Brii Biosciences, Tsinghua University, and the People’s Hospital of Shenzhen has accomplished the task in 20 months. It would usually takes 10 years. “It can reduce the rate of hospitalization and death by 80 percent,” said Zhang Linqi, leader of the research team.
The new antibody drug is immediately effective when conducted intravenously (静脉注射). Moreover, the treatment can protect people, especially those whose physical condition doesn’t allow vaccination, from becoming infected by COVID-19 for around nine to 12 months, said Zhang. How does it work? When a virus infects a cell, it relies on an important type of protein: the spike proteins on its surface. The spike proteins serve as a key to unlocking a cell. If a virus cannot enter a cell, it will be destroyed immediately. The job of our antibodies is to block the virus from entering cells. So its target is very precise. In addition, thanks to the coordination between the two antibodies, it is highly efficient and durable in controlling the virus, according to Zhang.
Lab tests suggest that the antibody combination can be effective against common COVID-19 variants, including the Alpha, Beta, Delta, Lambda and Mu. Testing with the newer Omicron strain is ongoing. The qualities of the new drug make it especially useful for high-risk groups, such as frontline medical workers and people who are not suitable for vaccination due to various possible health problems.
The new drug is expected to come to the market soon, but it’s not cheap. That’s because of limited production. Also, it typically must be administered intravenously in a hospital setting.
Noting that China has used science and technology to fight COVID-19 since the beginning of the outbreak, Zhang said: “Science is the core to solving the issue. Science has shown its power in all sectors, from medical treatment, medicine and vaccine development to prevention and control measures.”

The other day, I discover I couldn’t move my right arm and fingers after sleeping through a flight. Having diagnosed me with neural injury, the doctor suggested I could try acupuncture (针灸). So I followed his advices and began my treatment. Dozens tiny needles were inserted across my arm and fingers. I dared not move, because even a small change of position could cause a acute pain. Two weeks went by after I could eat a meal with chopsticks and it took a month for my arm and fingers to return back to their normal functions. I was very amazing at how magic these needles were. That I had always considered old-fashioned and useless turned out to be of great use. I hope acupuncture, with its help I recovered, will continue to bring health to other people.
6 . At some point, every dog owner has wondered if it would be possible to take everything their dog offers- peace, love, charm and wit- and share it with others. After all, we know what subtle and powerful benefits come with pet ownership. Why not do a good turn by sharing it with those less fortunate?
Everyone loves dogs, and when people are going through hard times, the presence of a dog can be a huge comfort. Studies have shown that petting a dog lowers a person’s blood pressure and heart rate.
To become a therapy dog, your dog must be tested and registered with a local therapy dog society. There are several: Therapy Dogs International, Delta Society, Alpha Society,and St John Ambulance.
In order to register with a therapy dog group, you and your dog must take a test administered by a recognized evaluator.
| A．The act of touching a dog makes a person relax. |
| B．Maybe your dog would make a great therapy dog! |
| C．Most therapy programs will only admit registered dogs. |
| D．Dogs can be of any size, and cats make great therapy animals, too! |
| E．Researchers have learned that a good therapy dog manages to change the entire situation. |
| F．Therapy dogs are well behaved, smart, and clean, with good manners and a good attitude. |
| G．The evaluator will watch to see how your dog behaves coming into a new situation, greeting a new person and so on. |

9 . You may want to bring honey the next time you have a cold, a study says. That's because honey has been shown to provide better cough relief than some over-the-counter drugs, Oxford University researchers said in findings published in BMJ Evidence-Based Medicine.
"Honey is more effective than usual care choices for improving upper respiratory tract infection(呼吸道感染)symptoms, particularly reducing cough frequency and cough severity," the scientists said in the findings.
Researchers said they reviewed 14 past studies about upper respiratory tract infections, also known as common colds. Symptoms can include runny or stuffy nose, sneezing, sore throat and coughing, according to the Centers for Disease Control and Prevention(CDC).
Four of the studies examined comparisons between honey and diphenhydramine, an antihistamine that can be used to relieve coughs, according to the U. S. government. It's sold at U. S. drugstores under several brand names and is combined with other ingredients(成分)in some cold medicines.
In their findings, Oxford scientists said honey was "significantly better than" diphenhydramine at improving cough symptoms. The results came from studies that included 385 participants, data show. But honey was "not significantly better" at cough relief when compared to another class of medicines, called dextromethorphan, according to a review of two studies with a combined 137 patients. Dextromethorphan is used to suppress(抑制)coughs.
Anyone sick with a cold should talk to a druggist or doctor about the best medicines for them, according to health officials. "Over-the-counter medicines may provide temporary relief of symptoms, but they will not cure your illness," the CDC said on its website.
The CDC includes honey on its list of possible ways to suppress coughs. Other tips for feeling better from a cold include getting enough rest, breathing in steam and using saline spray, according to the CDC.

10 . Some people look forward to getting braces (牙箍) on their tooth, thinking they look cool. Other people avoid visiting the orthodontist (正齿医生) until resistance becomes in vain. But anyone who benefits from the orthodontist's trade today should be thankful for the progress this science has made over the centuries.
Remains of crooked (弯曲的) human teeth date back tens of thousands of years. Greek and Roman texts describing the treatment of irregular teeth by the application of pressure date buck as far as the fifth century B.C. Archaeological evidence indicates even earlier use of orthodontic appliances, including man-made objects found in considerable burial sites in ancient Italy. Another early attempt at braces may have been discovered on Egyptian mummies with recognizable metal bands around their teeth. Thus, from at least 1,000 BC, it was known that teeth move in response to pressure.
Techniques for correcting dental irregularities did not advance much until the eighteenth century. French dentists led the way to building orthodontic practice on scientific foundations. The greatest contribution came from Pierre Fauchard. In 1728, Fauchard published the first general study of dentistry. In it, he described the process of straightening. He made smooth a crooked tooth to create space around it. Then he repositioned the tooth using a tool called a “pelican”. And he bound it to its neighbors and let it set. French and English dentists improved on Fauchard's work though the eighteenth century. Patients of Fauchard’s treatment may have been grateful when the work was complete. While many of them faced the treatment with fear and cried during the procedures, there were many Frenchmen who flooded to Fauchard to improve their looks with dental work.
Pioneering European orthodontists introduced new techniques and instruments in the nineteenth century. By midcentury, American dentists began to take the lead in research and invention. Electricity revolutionized the operating room, and the proper medicine made surgery less painful. John Farrar developed guidelines for using tools to move teeth by applying force at regular intervals.
The twentieth century saw refinement in the materials and methods of orthodontics. But the fundamental principles of the science were developed during the days of Fauchard.
