When you got sick,did your parents and doctors make you drink a“terrible soup”?【小题1】,but it can really make you feel better in several days.The“soup”is actually a kind of traditional Chinese medicine(TCM).

In recent years,TCM has become more popular around the world.【小题2】.China has 10 TCM centers abroad,such as in France and the United States.Doctors give TCM treatment to local people there.They also teach TCM knowledge to local people.Now,there are over 100,000 TCM clinics,with about 300,000 TCM workers around the world.

TCM came from China thousands of years ago.It is based on the Chinese philosophy（哲学）of yin and yang.Humans should follow the natural rules to keep healthy.Old Greece and Egypt created western medicine.【小题3】.Western doctors check people’s height,weight,blood pressure and body temperature.

【小题4】.“Bringing together western medicine and TCM can use collective knowledge,rather than create competition between them.It can develop the great effects of both of them,”said Bernhard Schwartlander,a World Health Organization representative in China.

On Dec 6,a government document reported that 86 countries and regions are now developing TCM together with China.In 2015,Chinese scientist Tu Youyou won the Nobel Prize.【小题5】.Today,with more and people paying attention to TCM,it will definitely have a bright future.

Walker didn't realize the dangers of e-cigarettes last December when he bought his first one. "I thought it was cool," says Walker, who moved to Florida Atlantic University a month later. Within weeks, given the pressures of adjusting to a new campus, he was smoking a pack or more a day. "After about a week and a half," he says, "I'd get nervous and anxious if I didn't have it."

In early March, Walker went to a hospital emergency room near campus complaining of chest pain, fever and feeling sick. "Eleven days later my chest hurt so bad that I couldn't even sit straight," says Walker. X-rays showed that Walker had what looked like pneumonia (肺炎) in his left lung. Within days, Walker was put on a respirator (呼吸器) and later sent by air to another hospital. "He was dying," says his mom, Candy, a nurse.

It took seven days for doctors to confirm that Walker's infection was caused by the adenovirus (腺病毒). But they were at a loss to explain how the virus had nearly killed an otherwise strong and healthy college student. The answer became clear in mid-April after his father Dave was terrified by what he found — so many e-cigarettes. "Most likely," says Dr. Hunley, "it was the e-cigarettes that led to his breath failure, which contributed to the spread of the adenovirus."

By the time Walker finally left the hospital in July he'd lost 80 pounds, and his left lung and both his kidneys(肾) had been destroyed. Doctors say he now needs to have the kidney transplanted. Walker admits he is shaken by his experience. Meanwhile, Candy says, "Every time I see someone smoking e-cigarettes, I show them pictures of Walker in the hospital and ask, 'Do you understand that you could end up like this?'"

A new breakthrough in material science could revolutionize medical implants. Scientists at Southeast University in China have developed a piezoelectric material that is not only highly effective but also biodegradable. This innovation surpasses previous biodegradable options by a factor of 13 in terms of piezoelectric performance.

Piezoelectric materials have the unique ability to convert mechanical energy into electrical energy. This property makes them ideal for various medical implants, like pacemakers and drug delivery devices. However, traditional options lack biodegradability, necessitating a second surgery for removal after serving their purpose. This additional procedure can be expensive and carries inherent surgical risks.

The newly developed material, the discovery of which was led by Zhang Hanyue and Professor Xiong Rengen, is a kind of ferroelectric molecular crystal. The crystal offers the remarkable combination of both piezoelectricity and biodegradability. Notably, the material boasts a piezoelectric coefficient (d33) of approximately 138 picocoulombs per newton, a significant 13-fold increase compared to previous biodegradable materials.

Furthermore, the material is conveniently combined with polyvinyl alcohol (PVA), granting it high flexibility and biocompatibility within the body. This translates to safe implantation that can eventually dissolve naturally, eliminating the need for removal surgery.

The researchers envision this innovative material being utilized in a diverse range of next-generation medical implants. This research, published in the March 29 issue of Science magazine, represents a significant leap forward in the field of medical implants. Media outlets in China called the discovery a landmark breakthrough since the discovery of the piezoelectric effect by the Curie brothers in 1880.
