1 . The old saying that “laughter is the best medicine” may contain an element of truth when it comes to heart health. A research has demonstrated that laughing causes the tissue inside the heart to expand and increases oxygen flow around the body.
“Our study found that laughter treatment increased the functional capacity of the cardiovascular (心血管的) system, and patients with heart disease who engaged in a course of laughter treatment had reduced inflammation (炎症) and better health.” said the lead author, Prof Marco Safffi, of the Hospital de Clinicas de Porto Alegre in Brazil.
In the trial, scientists carried out a first-of-its-kind study to examine if laughter treatment could improve symptoms of patients with heart disease. It involved 26 adults with an average age of 64, all diagnosed with the heart disease caused by plaque (斑块) buildup in the walls of the arteries (动脉) that supply blood to the heart. Over three months, half were asked to watch two different hour-long comedy programmes each week, including funny popular sitcoms. The other half watched two different serious documentaries, about heavy topics such as politics or the Amazon rainforest.
At the end of the 12-week study period, the comedy group improved by 10% in a test measuring how much oxygen their heart could pump around the body. The group also improved in a second measure that tested how well arteries can expand. They also had a blood test to measure several inflammatory markers, which indicate how much plaque has built up in the blood vessels and whether people are at risk of heart attack or stroke. The results showed that their inflammatory markers had significantly reduced compared with the documentary group.
“When patients with heart disease arrive at hospital, they usually have a lot of inflammatory markers.” said Saffi. “It’s really good news that laughter treatment is a good intervention that could help reduce inflammation and decrease the risk of heart attack and stroke.”

3 . Healthcare professionals in four Canadian provinces can now prescribe (开处方) their patients passes to National Parks thanks to a new program, PaRX, which stresses the health benefits of spending time in nature in helping to manage physical and mental health.
PaRx was founded by the B. C. Parks Foundation in November 2020 and was officially supported by Parks Canada last month. Health professionals who register (注册) with the program can offer their patients a Parks Canada Discovery Pass, making it the country’s “first national nature prescription program”. The Parks Discovery Pass typically costs about $57 per adult per year.
“We’re really asking doctors to prioritize patients who live close to Parks Canada sites so they’ll have more access and can make it part of their everyday lives, and also those for whom the cost of a pass might be a barrier to nature access,” said Melissa Lem, president-elect of the Canadian Association of Physicians for the Environment.
Studies have shown that spending time in nature has a range of health benefits—from lowering blood pressure and improving heart health to reducing stress and anxiety. PaRx recommends that patients spend at least two hours per week in the great outdoors, and at least 20 minutes each time, to get the most benefit.
The program is currently available in the Canadian provinces of British Columbia, Ontario, Saskatchewan, and Manitoba. It will eventually spread to every province.
PaRx also has benefits outside of the national parks, with many gardens offering free admission to visitors who show their prescriptions.
“There’s almost no medical condition that nature doesn’t make better. Rediscovering nature and then realizing how important it is to us has really shown that nature-health connection,” Lem said.

7 . China is one of the first countries to breed a medical culture. In comparison with Western methods, traditional Chinese medicine (TCM) adopts a vastly different approach. For thousands of years, Chinese people have accumulated rich experience in fighting all sorts of diseases, therefore forming a unique medical theory under the guidance of ancient Chinese philosophies (哲学).
The core behind TCM is that the human body's life is the consequence (结果) of the balance between Yin and Yang. Yang functions to safeguard us against outer harm, and Yin is the inner base to store and provide energy. When the balance between the two aspects is disturbed, people fall ill.
One of the traditional techniques of TCM, acupuncture (针刺疗法) means insertion of needles into superficial (表面的) structures of the body—usually at acupoints (穴位)—to restore the Yin Yang balance. It is often accompanied by moxibustion (艾灸疗法), which involves burning mugwort on or near the skin at an acupoint.
The first known text that clearly talks about something like acupuncture and moxibustion as it is practiced today is The Yellow Emperor's Inner Canon. It is the earliest and most important written work of TCM and is considered the fundamental and most representative medical text in China.
Acupuncture and moxibustion have aroused the interest of international medical science circles. And TCM is gradually gaining worldwide recognition. The WHO issued a document in 2002 that appealed to more than 180 countries to adopt TCM as an alternative in their medical policies. In 2010, acupuncture and moxibustion of traditional Chinese medicine were added to the Representative List of the Intangible Cultural Heritage of Humanity by the UNESCO. Presently, TCM has been back in the news for its effectiveness in improving the cure rate of the COVID-19 since its outbreak in January 2020.

9 . Doctors in hospital emergency rooms often see accidental poisonings. A frightened parent arrives with a child who swallowed a cleaning liquid. Or perhaps the harmful substance is a medicine. Or it might be a chemical product meant to kill insects. These are common causes of accidental poisoning.
In cases like this, seek medical help as soon as possible. Save the container of whatever caused the poisoning. And look on the container for information about anything that stops the effects of the poison. Save anything expelled from the mouth of the victim. That way, doctors can examine it.
Millions of people know a way to save a person who is choking on something trapped in the throat. The method is commonly known as the Heimlich Maneuver or abdominal thrusts(腹部按压), which you can do by getting directly behind a sitting or standing person. Put your arms around the victim’s waist. Close one hand to form a ball. Place it over the upper part of the stomach, below the ribs. Place the other hand on top. Then push forcefully inward and upward. Repeat the abdominal thrusts until the object is expelled from the mouth. For someone who is pregnant or very fat, place your hands a little higher than with normal abdominal thrusts.
Red Cross experts say taking these steps can save many lives. But they also warn that abdominal thrusts are not for people who have almost drowned. They say use of the method could delay other ways to re-start breathing in the victim. Abdominal thrusts should be used only in cases where a near-drowning victim is choking on an object.
To learn more about first aid, ask a hospital or organization like a Red Cross or Red Crescent Society for information. There may be training classes offered in your area.

10 . How to Do basic first Aid
Basic first aid refers to a temporary form of help given to someone who has been injured or has got sick due to choking, a heart attack, drugs or other medical emergencies.
Care for the person who has just gone through serious damage, including both physical treatment and emotional support.
Perform 30 chest compressions (心肺复苏) and two rescue breaths as part of CPR.
Make sure the person is warm as you wait for medical help. Remove some of your own clothing, such as your coat or jacket, and use it as a cover until medical help arrives. However, if the person has a heatstroke (中暑), do not cover him or keep him warm.
| A．Instead, try to cool him |
| B．Remember to stay calm |
| C．Perform first aid immediately |
| D．Here are some tips for first aid |
| E．It is important to take the correct chest compressions |
| F．In the center of the chest, put your two hands together first |
| G．If a person is in a state similar to sleep, he may need checking for breath |
