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.

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.    1     These teeth are in the very back of your mouth, two on top and two on the bottom as part of a complete set of 32 adult teeth.

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.    2    .

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.    3    After that, they’ll clean the area and pack it with cotton to stop bleeding.

    4    Everyone responds differently. In general, you can expect mild discomfort, slight bleeding, facial swelling (肿), and other common complications following the surgery, as your mouth needs a few weeks to completely recover.

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.    5    That way, your teeth won’t hurt when you eat and food bits won’t get stuck in your mouth.

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.

10 . Charles Richard Drew’s great invention directly contributed to saving thousands of lives during World WarⅡ, and continues to contribute to the life-saving work of the entire world of medicine later.

Born in 1904, Drew was the eldest of five children. He was intelligent and showed a talent for studies and sports from a young age. In 1922, his athletic ability earned him an athletic scholarship to attend Amherst College in Massachusetts. Drew graduated from Amherst College in 1926. In 1928 he applied to medical schools and was admitted to MeGill University in Montreal, Canada. He completed his medical degree and master’s degree in surgery in 1933.

Upon graduation, as an internship (实习生), he began to look at issues related to blood transfusions.

When he began his doctoral studies at Columbia University, with a physician named John Scudder, Drew continued his research in the field of blood transfusion. The two have jointly conducted research into blood preservation and fluid replacement, leading to the development of an experimental blood bank, which ran smoothly for seven months.

Drew’s breakthroughs in blood preservation were timely, as the World War II was raging in Europe at the time. Under Drew’s direction, his team has developed new ways to extract, preserve and transport plasma (血浆) on a large scale.

Following the success of the “Blood for Britain” program, Drew was appointed the assistant director for the US blood banking system. During this time, he built a number of mobile blood donation stations, later known as blood delivery stations.

On April 1, 1950, tragedy struck. Drew was injured in a serious car accident while on his way to a conference and died from his injuries. Many medical colleges and schools have been named after him to honor his contribution.
