Reasonable people should not have blind faith in the medical profession.
While it is true that modern Western medicine has risks, we shouldn’t reject it totally.
If this is the case why has “alternative” health care become so popular in North America and Europe? Often the fear of surgery motivates people to look for these alternatives. Many people think that these treatments will help even when the situation seems hopeless to Western doctors.
| A．Some alternative treatments are ineffective. |
| B．In addition everyone wants to be treated warmly. |
| C．We have to realize that there will be risks in almost any treatment. |
| D．Alternative treatments are attractive because they seem less harmful. |
| E．Patients who trust their doctors are more likely to follow treatment plans. |
| F．We all have to get more information about the treatments that we are given. |
| G．The harm to the patients usually comes from not getting medical treatment immediately. |

【推荐1】Pioneers of the research that led to one of the first COVID-19 vaccines (疫苗) say breakthroughs obtained in their studies could point the way toward developing a potential vaccine against cancer before the end of the decade.
Ugur Sahin and Ozlem Tureci, co-founders of BioNTech said technology they had developed could aid the immune (免疫) system respond to cancer cells. The mRNA COVID-19 vaccine stimulates cells to generate spike proteins, which warn the body’s immune system about things to look out for and to attack.
It is hoped that this could be reworked using proteins found in cancer tumor (肿瘤) cells, causing a similar bodily defensive action.
BioNTech was founded in 2008 specifically to work on cancer treatments. “Our focus has always been on achieving the full potential of the body’s immune system to successfully help handle cancer and infectious diseases,” says the company website.
Some of those earlier cancer vaccine developments have reached the clinical trial stage. “As scientists we are always hesitant to say we will have a cure for cancer,” said Tureci. “We have gained a mass of breakthroughs and we will continue to work on them. . . this will definitely quicken also our cancer vaccine.”
Luke O’Neill, professor of biochemistry at Trinity College Dublin, said that such a breakthrough would be “the Holy Grail” of cancer research, He added that it enabled the body to recognize a cancer tumor as a foreign element, in the same way it had done with COVID-19, and to respond accordingly, so that the immune system could be “trained” to “hunt down” the abnormal presence.
What made the potential breakthrough even more inspiring, he said, was that any treatment could be personalized to work on an individual cancer patient’s specific circumstances. “You can take someone who’s got cancer, take their own tumor and make an RNA vaccine out of that and improve their own immune system specifically against their own tumor. That’s a really awesome thing to see,” he added.

【推荐2】Many college students turn to ADHD (注意缺陷障碍) medicine during the exam week, which is regarded as “smart drugs” that will help their academic performance. The thinking is that if the drugs help students with ADHD improve their focus, they should provide the same benefit for people who don’t have the disorder.
But a new study shows that drugs can actually damage brain function of healthy students who take the drug hoping to boost their intelligence. “It’s not a smart drug which will suddenly improve their ability to understand information they read,” said Lisa Weyandt, a professor at the University of Rhode Island.
To test whether this effect is real or not, researchers organized 13 students to take part in two five-hour study sessions (一段时间) in the lab. The students took the standard 30mg ADHD drugs before one session, and a sugar pill before the other. Students on ADHD drugs did experience an increase in their blood pressure and heart rates. “The medicine was having an effect on their brain,” Weyandt said. The students also showed an improvement in their ability to focus, the researchers found.
However, students on ADHD drugs experienced no improvement in reading comprehension, reading fluency or knowledge reviews, compared to when they’d taken a sugar pill. “We read aloud stories to them and asked them to recall information from the stories,” she said. “That didn’t improve.”
Worse, the ADHD drug actually harms students’ memory. It’s often misused because people pull all-nighters and they’re tired, and they think it’s going to keep them awake. Maybe it does, but it’s certainly not going to help their academic work. The brain is still developing until the mid to late 20s. It’s important to keep it healthy. There’s also a chance that ADHD drugs could endanger a student’s heart health.

【推荐3】Study shows that wearing masks outdoors can protect against more than Covid-19 for people who suffer from seasonal allergies. Protection varies mask to mask, depending on the fit and, for cloth masks, the weave of the fabric. And unless you wear a mask at all times, you may still be affected by indoor dust or other things carried through open windows.
● Protect your eyes.
● Wash and change your mask frequently. “The last thing you want is allergen getting trapped in it,” Dr. Parikh, an allergist and immunologist at N.Y.U. Langone Health said. She recommends patients change their clothes when they get home and shower before sleep, to ensure that pollen doesn't stick to their skin, and wash reusable masks frequently.
● Find a mask that doesn’t make your skin painful. Choosing the right mask for an allergy-prone wearer can also be important. People with sensitive skin may react to dyes in some fabric masks and should use perfume-free detergents.
●
| A．Wear glasses or sunglasses when you’re outside. |
| B．Talk to a doctor if your allergy symptoms are severe. |
| C．There are more tips to reduce your symptoms in allergy seasons. |
| D．Wearing a mask also makes the air through our nose much warmer. |
| E．Or choose a medical grade mask which is less likely to irritate skin. |
| F．Give up our masks if we head into another pandemic season in the future. |
| G．The Center for Disease Control recommends washing a cloth mask after each use. |
