In July, the "Science" rumor list released that erythromycin ointment is a "panacea".
Teenagers should not get the new crown vaccine because of the side effects? Don't believe it
With the progress of the anti-epidemic work, in July, many places across the country, including Beijing, have launched the new crown vaccination for people under the age of 18.
According to data accumulated in clinical trials and expert review and argumentation, it is fully proved that the vaccine is safe for people aged 3 to 17 years old, and the ability to induce antibodies is very strong.
But that's it, the rumors of the "black" vaccine are resurrected. There are rumors that "the new crown vaccine is effective for adults does not mean that it is also effective for teenagers, and even has greater side effects on teenagers, so it should not be vaccinated." Don't believe this statement!
The latest "science" rumors list was released. In addition to the above-mentioned rumors surrounding the new crown vaccine, erythromycin ointment is the "universal medicine". Pseudo-knowledge such as eating plant meat and low calorie energy to lose weight are all on the list.
The monthly "science" rumors list is guided by the Beijing Science and Technology Association, the Beijing Municipal Internet Information Office, and the Capital Internet Association. The Beijing Science and Technology Journalists and Editors Association and the Beijing regional website jointly publish the rumor rejection platform.
Rumor 1
Erythromycin ointment is the "panacea"
Truth: Whether it's skin allergies, acne, or mosquito bites, just apply a little erythromycin ointment?
Erythromycin is an antibiotic drug. Long-term use or abuse can lead to the occurrence of drug resistance of pathogens, that is, bacteria can kill antibacterial drugs "inaccessible". The more resistant bacteria, the more difficult the treatment of infections.
Before using erythromycin ointment, you should consult a physician or pharmacist, and use it after getting confirmation and giving appropriate medication instructions.
The main component of erythromycin ointment is erythromycin, which is a relatively common antibacterial drug and has good antibacterial activity against most gram-positive bacteria such as Staphylococcus.
Erythromycin ointment is an anti-infective medicine and is not suitable for mosquito bites and allergies.
The indications mentioned in the instructions for erythromycin ointment include: purulent skin diseases such as impetigo, small burns, ulcer infections, and acne vulgaris.
It should be reminded that not all acne requires the use of erythromycin ointment. Antibacterial drugs are not required when the symptoms are mild and there is no infection. When the hair follicles are blocked and cause folliculitis, the application of erythromycin ointment is symptomatic. of.
Rumor 2
Teens should not get the new crown vaccine
Truth: There are rumors that the new crown vaccine is effective for adults does not mean that it is also effective for teenagers, and even has greater side effects on teenagers and should not be vaccinated.
This statement is baseless and it is necessary for young people to start the new crown vaccination.
According to the Beijing Center for Disease Control and Prevention, on the one hand, the vast majority of people in my country are not immune to the new coronavirus and are susceptible to the new coronavirus.
After vaccination, the vast majority of people can gain immunity, thereby effectively reducing the risk of morbidity, severe illness and death; on the other hand, vaccinating young people with the new crown vaccination will build an immune barrier for the population, block the epidemic of new crown pneumonia, and restore my country as soon as possible The normal operation of social economy and residents’ lives is of great significance.
On July 20, 2021, Beijing will fully launch the new crown vaccination for people aged 12 to 17 years.
The new coronavirus vaccine used by people aged 12 to 17 this time is an inactivated new coronavirus vaccine approved by the relevant state departments and can be used for people of this age group.
Based on the data accumulated in the expansion of clinical trials for the 3 to 17-year-old population and expert review and argumentation, it is fully proved that the vaccine is safe for the 3 to 17-year-old population, and the ability to induce the production of antibodies is very strong.
According to the schedule, Beijing has initiated vaccination for people in high school (15 to 17 years old) in advance, and vaccination for people in junior high school (12 to 14 years old) in early August.
Among them, the school students will be vaccinated in an orderly manner according to the inoculation order of high school (including technical school), junior high school, and special education school. Schools or districts will organize the work of the school or district as a unit.
Those who are not in school between the ages of 12 and 17 will be vaccinated according to employment and non-employment arrangements.
Employed people aged 16 to 17 are organized by the competent authorities of various industries and districts to coordinate and organize to designated vaccination points for vaccination.
Non-employed people (including those who are 12-17 years old to study abroad) will be vaccinated at designated vaccination sites by the neighborhood (township) where they are located.
According to incomplete statistics, in addition to Beijing, Guangxi, Hubei, Heilongjiang, Hunan, Anhui, Fujian, Jiangsu, Guangdong and other places have already specified the new crown vaccination for children aged 12 to 17, and most areas will start from July. Vaccination started for people aged 15 to 17 years old, and in August for people aged 12 to 14 years old.
Rumor 3
Eat plant meat with lower calories to lose weight
The truth: Eating plant meat online can help reduce fat and body shape, and can effectively lose weight.
Is it really?
The name "plant meat" can easily be classified as a light vegetarian food such as vegetables and tomatoes.
But in fact, plant meat is not always vegan, and the calories are not necessarily low.
The ingredients of vegetable meat usually consist of soy protein, drinking water, vegetable oil, edible salt, etc., and a series of related food additives.
Among them, fat is one of the very important additions to plant meat.
It can improve the texture of plant meat and produce a tender and juicy taste similar to real meat.
These added fats can come from sunflower oil, rapeseed oil, or solid palm oil.
In addition, the extra starch and seasoning used to make the plant meat taste more delicious, while at the same time increasing the calories.
The latest statistics on the nutrition data of a plant-based artificial meat from the US Department of Agriculture show that 100 grams of plant meat can produce about 221 calories, which is not much different from the calories of 100 grams of beef (250 calories).
Rice, the staple food that people who lose weight avoid, has only 129 calories for 100 grams of calories.
A few mouthfuls of plant meat will top the heat of a bowl of rice.
Therefore, don't expect to rely on plant meat to lose weight.
Rumor 4
"Glucose standard" changed
The truth: "The new blood glucose standard in 2021 has been corrected and changed to 4.4-7.0mmol/L". Is this news true?
In fact, since 1999, the WHO officially recognized the diagnostic cut-off point of diabetes as: fasting blood glucose ≥ 7.0 mmol/L or 2-hour postprandial blood glucose ≥ 11.1 mmol/L. This standard has been used internationally for 22 years and has not changed.
The "new blood glucose standard updated in 2021" in the legendary law actually refers to the latest version of the "Chinese Type 2 Diabetes Prevention and Control Guidelines (2020 Edition)" released by the Diabetes Association of the Chinese Medical Association in 2021.
"4.4-7.0" refers to the "blood glucose control target" in this version of the guidelines. For most patients with type 2 diabetes, the guidelines recommend that fasting blood glucose be controlled within the target range of 4.4-7.0 mmol/L; for non-fasting blood glucose, it is recommended Not more than 10mmol/L.
The "blood glucose control goal" here should not be confused with the aforementioned "blood glucose diagnostic criteria".
In addition, the data of 4.4-7.0mmol/L is completely consistent with the old version of the "Guidelines for the Prevention and Treatment of Type 2 Diabetes in China (2017 Edition)" and has not been corrected.
Blood glucose control goals and blood glucose diagnostic criteria are completely different concepts. Don't be biased by articles that aim to attract eyes.
Rumor 5
Net celebrity cooling spray is safe and reliable
The truth: The recently popular cooling spray is known to be sprayed on clothes, hats, or in the car. It is safe and reliable, and it can cool down immediately.
Is there really such a safe and effective heat relief artifact?
For the cooling spray, firefighters from the Jiugong Special Service Station of the Fire Rescue Detachment of Daxing District, Beijing did relevant experiments.
Firefighters successively used two cooling spray products with the main ingredients of tetrafluoroethane and LPG, and sprayed them to the burning igniter. As a result, the cooling spray burned violently after encountering an open flame.
Then, the firefighting officers sprayed the spray with the main ingredient of ethanol into the dish containing the pork. When it encountered an open flame, the surface of the pork quickly burned.
The staff of the Old Palace Fire Special Service Station said: "This is because the net celebrity cooling spray contains flammable substances such as tetrafluoroethane, LPG, ethanol, etc., if this type of spray encounters an open flame during use, it will quickly cause a combustion reaction. . Therefore, after using this type of spray, never go into the kitchen to cook, smoke or ignite, etc. It is very easy to cause fires, and the safety hazards are relatively large."
The firefighters also simulated a confined space similar to a carriage, put the cooling spray and the thermometer in it, exposed to the sun, and observed the changes in the spray bottle.
When the temperature in the experimental space exceeds 58°C, the thermometer can no longer work normally, and the bottle of the cooling spray begins to expand sharply, the bottle cap is violently ejected, and the spray can is also poured.
After continuous exposure to the sun, with a loud noise, the cooling spray tank exploded, the base was blown up, severely deformed, and the confined space and thermometer used in the experiment were blown apart.
The staff of the Old Palace Fire Secret Service Station said: “Once such net celebrity cooling sprays are used carelessly, the consequences will be disastrous. Consumers are reminded to use them with caution.”
