October's "Science" rumors list is released: Can't exercise if you have rheumatoid arthritis?

Found that the nodule will become cancerous in the future if it is not removed immediately?

too exaggerated

Can eating Banlangen be able to resist the new crown?

Out of context

  When I heard that "Compound Banlangen can effectively resist the new crown virus", did you follow the trend and stock up?

Don't rush to dry this cup of "Banlangen", the official rumor is coming, the above statement is "out of context", and random consumption may also cause side effects.

In October, the scientific rumors list was released, packaging and exposing recent popular health rumors to help you recognize the true colors of these false health knowledge.

  The "Monthly'Science' Rumor List" is under the guidance of the Beijing Municipal Science and Technology Association, the Beijing Municipal Office of the Internet Information Office, and the Capital Internet Association, and is jointly released by the Beijing Science and Technology Journalists and Editors Association and the Beijing regional website in conjunction with the rumor rejection platform.

Rumor: If the nodule is not removed immediately, it will become cancerous in the future

  Truth: Nodules, in layman's terms, refer to relatively small non-feeling or painful lumps.

Nodules may be seen and felt on the neck, underarms, breast, and subcutaneous parts of the body.

However, there are some nodules that grow in "secret corners" and are not easy to find. For example, nodules on the lungs, liver, kidneys, heart and other organs can only be discovered with the help of imaging tests.

  Don't overstress the nodules, more than 90% of the nodules are benign.

Benign nodules generally do not need to be treated, and some nodules are benign throughout their lives, such as scarred nodules (a kind of nodules formed in the process of repairing the human body after trauma, which will not change with life).

However, once it is found to be a nodule, it needs to be observed at any time and go to the hospital to determine the benign, malignant and grade of the nodule.

  Touchable nodules like breast nodules can sense changes in the size and hardness of the nodules. Nodules that grow on the limbs and body surface should be observed and touched at any time.

The lung nodules require professional examination.

If you are not sure whether it is a nodule, it is recommended to go to the hospital.

  It is important to pay special attention to "undifferentiated removal" of nodules, because removal of nodules will also have a certain impact on the body.

After removing the nodule, it will cause some damage to the local tissue of the affected area.

For example, breast nodules, after removal, may cause damage to the breast ducts; removal of lung nodules may require removal of part of the lung lobes, which affects lung function.

In short, whether or not to remove the nodule, when to remove the nodule, requires a doctor to make a decision based on the situation.

Rumor: Compound Banlangen can effectively resist new coronavirus

  The truth: On October 13th, the team of Academician Zhong Nanshan mentioned in a seminar that the research team found that the compound Banlangen granules and Kouyanqing granules showed different degrees of in vitro inhibitory drugs in the in vitro drug efficacy screening against the new coronavirus. effect.

  After relevant media reports, Banlangen quickly became popular, and pharmacies and e-commerce platforms were out of stock.

On the evening of the 18th, the relevant pharmaceutical company issued a clarification announcement, stating that the relevant conclusions involved in the relevant media reports are only the results of the in vitro screening of anti-new coronaviruses against the compound Banlangen granules, and further related work on the product is required. There is a certain degree of uncertainty.

  Academician Zhong Nanshan also responded: "Compound Banlangen, not Banlangen, has an anti-coronavirus effect in the laboratory, which is far from being effective in the body... Someone has taken my sentence out of context and expanded it to even say that it is Banlangen. A kind of distortion, the relevant departments have come out to clarify. "A drug must go through three stages before being used in clinical treatment: in vitro testing, animal testing and clinical testing.

The results made by the laboratory on cells in vitro are still a long way from being clinically effective.

For example, 75% alcohol can kill the virus, but it can only be used for external disinfection, not oral administration.

Shuanghuanglian, which was sold out before, is only effective in vitro, and there is no evidence that clinical treatment is effective.

  Even if the drug is already on the market and in vitro tests prove its inhibitory effect on the virus, clinical trials cannot be omitted.

Even if it is just to add a new indication, it needs to pass a certain sample size clinical trial to prove its safety and effectiveness before it can be officially used on patients.

  Until the Phase III clinical trials are completed, no one can say whether the compound Banlangen is effective.

There is no need to follow the trend to buy, and it is not recommended to take drugs as a way to prevent diseases. Taking it randomly may also cause side effects.

Rumor: Nine people died of Aspergillus flavus poisoning after eating "sour soup"

  The truth: the "sour soup" poisoning is caused by the high concentration of orychotic acid produced by the Pseudomonas cocos pollution, not the excessive aflatoxin.

Aflatoxin is a toxin produced by the "Aspergillus flavus" mold. It is one of the strongest carcinogens known to man.

But in this incident, even if the aflatoxin in the food exceeds the standard, it is difficult to reach the lethal dose.

Aflatoxin has a bitter taste, and it is difficult not to be noticed when it reaches a lethal amount that causes acute poisoning.

Deaths caused by aflatoxin are very rare, and the mortality rate is not so high.

  Poisoning caused by rice yeast acid is not uncommon.

The longest incubation period of poisoning is 3 days, most of which are half a day to one day.

The patient has only mild symptoms such as nausea, vomiting, diarrhea, dizziness, and general weakness in the initial stage, and then may develop jaundice, hepatomegaly, subcutaneous hemorrhage, hematemesis, hematuria, oliguria, unconsciousness, restlessness, convulsions, convulsions, shock Symptoms such as coma.

At present, there is no specific detoxification drug for the rice yeast bacteric acid, patients generally do not have a fever, and the mortality rate of severe patients is very high.

There are three main categories of foods that are easy to be contaminated and cause acidosis: fermented cereal products (fermented corn flour, glutinous corn glutinous rice ball powder, corn starch, fermented glutinous millet, glutinous rice cake, rice cake, vinegar jelly, etc.); potato products ( Potato vermicelli, sweet potato noodles, yam starch, etc.); spoiled fungus, white fungus, etc.

  To effectively prevent rice yeast acidosis, we must first master the correct preparation method.

Do not use moldy corn and other raw materials to prepare fermented rice noodle products; change the water frequently when soaking the cereals, keep it sanitary and have no peculiar smell; dry or dry it into powder in time after grinding; the storage environment should be ventilated and moisture-proof, and do not directly touch the soil. Prevent pollution.

Second, the sale and consumption of fresh white fungus is prohibited.

To ensure the quality of the cultured white fungus, the fresh white fungus should be dried in time or fully exposed to ultraviolet light.

Third, correctly distinguish the quality of white fungus.

After the dried white fungus is soaked in water, the flower shape is complete and large, the fungus pieces are white or slightly yellow, with good elasticity and no peculiar smell.

Deteriorated white fungus is not shaped, sticky, and inelastic, and the fungus pieces are dark yellow to yellowish brown with peculiar smell.

The made white fungus should be rinsed thoroughly and the base of the white fungus should be removed.

 Rumor: You can never exercise if you have rheumatoid arthritis

  The truth: Rheumatoid arthritis is a chronic and systemic autoimmune disease with symmetry and polyarthritis as the main manifestations.

As the disease progresses, the patient's joints will be damaged or even deformed, swelling and painful during activities.

  In patients with rheumatoid arthritis in the acute stage, the joints are obviously swollen and painful, accompanied by mild edema of the tissues around the joints, local temperature increases, and tenderness.

At this time, the patient's joint movement is limited or completely unable to move.

In the acute phase, patients should stay in bed, take medications on time, limit swollen and painful joint activities, and avoid weight bearing, excessive activity, and cold stimulation.

Avoid pressure on swollen and painful joints during rest to avoid aggravating joint swelling and pain.

  After the medication relieves the symptoms and the acute phase is over, the patient should undergo functional recovery training, which mainly includes joint and muscle training.

Patients with rheumatoid arthritis can perform finger joint training, which mainly includes finger extension and flexion movements.

When training, start from the distal interphalangeal joints, to the proximal interphalangeal joints, and then to the metacarpophalangeal joints.

Extend and flex as much as possible. It can be done with one finger or with multiple fingers.

Be careful not to over-activate during activities, and do not use sudden force to prevent damage to the joints.

In addition to joint training, patients can also perform some aerobic exercises.

Aerobic exercise can not only relax the muscles and relieve the spasm of the tissues around the joints, but also facilitate blood circulation and promote the dissipation of inflammation.

  Appropriate activities can greatly promote the functional recovery of patients with rheumatoid arthritis in remission. It can also improve the self-care ability of patients and help patients build confidence.

Rehabilitation training requires long-term persistence, and therefore requires the cooperation and supervision of the patient's family members.

Only by insisting on early functional exercise can reduce the degree of joint damage caused by disease and improve the quality of life.

Rumor: This winter is the coldest winter in 60 years

  The truth: during the National Day holiday this year, affected by the strong cold air, the lowest temperatures in Northeast and North China dropped below the freezing point. Many scenic spots in Henan, Sichuan, Gansu, Inner Mongolia, Jilin, Heilongjiang and other places "unlocked" the winter scene mode early.

As the temperature drops, many news about "the coldest winter in 60 years" and "all of which are related to La Niña" circulated on Weibo, WeChat, Moments of Friends, and forums.

  But in fact, in early October, it is normal for the temperature to drop to freezing point and even snowfall in northern my country, especially Inner Mongolia and Northeast China.

Experts from the China Meteorological Administration believe that the cooling process is not necessarily related to La Niña.

The La Niña phenomenon refers to the sea surface temperature of the central and eastern Pacific Ocean at the equator, which is generally colder than the same period of the year.

Generally speaking, in the winter during the peak of most La Niña events, the cold air activities affecting my country are more frequent than normal, and the temperature in the central and eastern regions of my country is more likely to be lower than normal.

  In addition, based on La Niña alone, it is impossible to determine that the winter will definitely be cold. The impact of each La Niña event is not the same. Not every La Niña year’s winter average temperature in my country is low.

Moreover, in the context of global warming, the factors affecting my country’s winter climate are more complex. Factors such as the melting of Arctic sea ice and changes in snow cover in Europe and Asia will all affect the East Asian winter monsoon circulation, which in turn affects my country’s winter climate.
