Eating cold medicine can cause liver failure? Is the X-ray security instrument harmful? Are these October "science" rumors unreliable? The truth is here.
1. The thrombus aspiration device came out and the heart stent was eliminated?
Rumors : Since July 1, 2016, a hospital in Taiwan has invented a new technology that can suck out blood vessel sediments and no longer need to put stents.
Truth: A blood clot can fall off somewhere in the heart or it can be solidified by a blockage. For thrombus, there are two types of suction devices: one is manual and the other is mechanical. For patients with coronary heart disease without acute myocardial infarction, although the blood vessels are narrowed to more than 80%, there are no fresh thrombus, mostly due to calcified plaques attached to the vessel wall, very hard and irregular. There is no use at all.
In fact, domestic thrombus aspiration catheters have been used for many years in the case of acute myocardial infarction, and the technology is indeed improving, but there is no such "new technology" to replace the stent.
2. Long-term use of pencils can lead to lead poisoning?
Rumors: The recent "children's blood lead exceeded" incident has been largely related to "biting pencils".
Truth: Will long-term use of pencils lead to lead poisoning? People who have this kind of question often think that the pencil lead contains lead, and the use of lead-containing pencils naturally leads to lead poisoning.
Does the pencil lead contain lead-free? It is said that in the 16th century AD, in a place called Borrowdale in England, a black mineral, graphite, was discovered. Soon, some local shepherds found that they could use graphite to mark the sheep. Later, in the Napoleonic army, there was an officer named Conte. After repeated trials, he mixed clay into the graphite and placed it in the kiln to make a pencil core that was very durable in the world.
In the production process of pencils, the metal of lead was not used at all. Of course, the habit of biting a pencil still needs to be changed. The wooden pole of the pencil is usually coated with colored pigments. If the pigment contains traces of heavy metals or other harmful substances, the harmful substances tend to enter the human mouth during the biting process.
3. Is there a huge security risk hidden by eating cold medicine?
Rumors: Overdose of cold medicines containing acetaminophen may cause liver failure, and people who take these medicines are ignorant of themselves on the verge of death.
Truth: Commonly used over-the-counter cold medicines such as Kangkang, Tylenol, 999 Ganmao Ling Granules, all contain a component called acetaminophen, which is used to treat common pain and fever symptoms in colds. Acetaminophen is currently known as an antipyretic analgesic that is safe and effective and has fewer adverse reactions in the digestive tract.
The risk of liver damage caused by acetaminophen occurs at the same time taking a variety of pharmaceutical preparations containing acetaminophen, or increasing the dose (more than 4 grams of acetaminophen 24 hours maximum safe dose), or long-term use Case. Studies have shown that long-term alcoholics take large doses of acetaminophen with increased hepatotoxicity, even at normal doses can lead to some human-specific liver damage. Children and patients with underlying liver disease are more likely to have liver damage using such cold medicines.
Although the acetaminophen component of the cold medicine is potentially harmful, it does not need to be regarded as a flood beast. Drugs have different adverse reactions, and the correct use of drugs can better play a therapeutic role and reduce the occurrence of adverse reactions.
4. Can I sleep for 15 hours after drinking “sleeping water†in Japan?
Gossip: Office workers frequently work overtime, stress, and can't sleep. It doesn't matter, a "sleeping water" from Japan lets you sleep for 15 hours and sleep unconscious.
Truth: The main ingredients of “Sleep Water†are the same as ordinary beverages. There is no water, sweetener, minerals, vitamins, flavors, etc. The only ingredient that can be called “improving sleep†is called “left-handednessâ€. A substance of theanine.
What is the sacredness of L-theanine? With it, you can get gold sleep? In this regard, Shen Yuan, director of the Department of Psychology and Psychology of the Tenth People's Hospital of Shanghai, said that theanine is an amino acid found in tea. There is no reliable evidence that it has a sedative and sleep-preventing effect. In fact, from the perspective of psychology, the reason why "sleeping water" can be "effective" is more psychological suggestion.
5. Low tar cigarettes reduce focus and reduce damage?
Rumors: Low tar cigarettes can “defocus and reduce harmâ€, reduce the content of tar in tobacco, solve the harm caused by tobacco to smokers, and contribute to tobacco control.
Truth: Why do smokers actually consume more tar than the amount of tar on the pack? According to expert analysis, when measuring by machine, the venting holes around the filter can dilute the inhaled tobacco smoke and reduce the measured tar concentration, but during the actual smoking process, because the vent hole is partially or completely blocked by fingers or lips. The venting holes do not really act to dilute the tobacco smoke.
The so-called low tar cigarettes do not reduce the risk of smoking, and there is no safe level of smoking. When the smoker smokes, the actual intake of harmful substances is greater than that measured by the smoking machine. The composition is also much more complicated. It is not possible to assess the smoker's intake and health risks based solely on the amount of release.
6. Does the X-ray security device cause great harm to the human body?
Rumors: The "weak photon human body security instrument" used in Chengdu Shuangliu Airport is actually using X-rays for perspective scanning, which will cause serious harm to human health.
Truth: Whether the X-ray security device is harmless or not, it depends on the X-ray dose radiated by the security device. According to the "Basic Standards for Protection of Ionizing Radiation and Safety of Radiation Sources" formulated by China, the incident dose of X-ray machines should not exceed 10mGy in a single use; according to media reports, the "weak photon human body security instrument" of Chengdu Shuangliu International Airport once The amount of radiation is controlled within 0.2 μSv (1 Gy = 1 Sv = 1000 mSv = 1000000 μSv). Therefore, there is absolutely no need to worry about the amount of radiation at this point.
However, due to the cumulative effect of X-rays, the use of security devices requires great care. If a small dose of X-rays is encountered everywhere, there is a risk of accumulating excessive amounts without knowing it. Therefore, the Ministry of Environmental Protection has sent a letter to the Sichuan Provincial Environmental Protection Department asking them to illegally produce, sell, and use X-ray human body security equipment, and order them to immediately stop illegal activities and ensure public safety.
