Medical knowledge ppt 1. What should be included in the production of ppt for ten minutes of internal medicine diseases?
10 minutes it seems impossible to explain a disease to medical students or listeners, so I guess you should do it like a popular science PPT, and I will answer it according to my own understanding.
1. First of all, the number of PPT should not be too much. If it usually takes 10 minutes, you can probably use 10- 15 PPT. The number of words in each PPT should be controlled. If there are too many words, the font should be reduced, and the small words on the full screen look hard and ugly. It's better to add some explanatory illustrations.
2. The main contents should include the name of the disease, accurate definition, etiology overview, main symptoms and signs of complications, main diagnostic basis and corresponding auxiliary examination, prevention and treatment strategies and prognosis.
3. The core content is what the public should pay attention to, so it is necessary to make clear the key points: (1) people who need to pay attention to or screen diseases (high-risk groups), and (2) why we should pay attention to diseases (such as high mortality and disability rate, serious complications, seriously affecting the quality of life, etc.). (3) How to actively prevent (primary prevention) and how to prevent complications after illness (secondary prevention).
4. For the specific treatment strategies and means, you can briefly introduce them without going into details, because it requires further communication with doctors, and it is not comprehensive to transmit such information only by popular science.
2. Little scientific knowledge
1。
Why do the stars twinkle? We see the stars shining, not because the luminosity of the stars has changed, but because of the occlusion of the atmosphere. The atmosphere is between us and the stars. When starlight passes through the atmosphere, it will be affected by the density and thickness of the atmosphere.
The atmosphere is not absolutely transparent, and its transparency will change according to its density. So when we look at the stars through it on the ground, we will see that the stars seem to be flashing.
2。 Why do people yawn? When we feel tired, a lot of carbon dioxide has been produced in our bodies.
When there is too much carbon dioxide, oxygen must be supplemented to balance the needs of the body. Because these residual carbon dioxide will affect our body's functional activities, then the body will send out a protective reaction, so we yawn.
Yawning is a deep breathing action, which will let us breathe in more oxygen and expel more carbon dioxide than usual, and it can also eliminate fatigue. 3。
Why can snakes walk without feet? Snakes have many scales, which are the outermost armor on their bodies. Scales are not only used to protect the body, but also to be their "feet".
When a snake crawls forward, its body will be S-shaped. Every scale outside the S-shape will tilt upward to help the snake catch the uneven road when it moves forward.
These scales cooperate with the muscles of the snake and can push the body forward, so the snake can walk without feet! 4。 Why do sunflowers always bloom towards the sun? There is a substance called "auxin" in the stem under the sunflower disk.
This substance has the function of accelerating replication, but it is anti-optical, and it will run to the backlight side whenever it encounters light. So when the sun rises, the stem of the sunflower immediately hides to the side of the backlight, as if the whole plant is bent in the direction of the sun.
5。 Why does the hair turn white when people are old? There is a substance called melanin in our hair. The more melanin, the darker our hair will be.
Without melanin, hair will turn yellow or white. When human beings reach old age, various functions of the body will gradually decline, and the formation of pigments will be less and less, so the hair will gradually turn white! 6。
Why do fireflies glow? Fireflies emit light because there is a luminous body at the end of their abdomen, which is filled with a lot of phosphorus-containing luminescent substances and luminescent enzymes, so that fireflies can emit flashing light. The purpose of fireflies is not only lighting, but also courtship, vigilance and trapping.
This is also a communication tool for them. Different kinds of fireflies emit light in different ways, frequencies and colors, so they can convey different information. 7。
Why do you growl when you are hungry? When you are hungry, you will purr. This is because the food you have eaten before has almost been digested. Although the stomach is empty, the gastric juice in the stomach will continue to secrete. At this time, the contraction of the stomach will gradually expand, and the liquid and gas inside will be stirred up and purr.
Don't be embarrassed by your stomach growling next time! Because this is a normal physiological action. 8。
Why can't ostriches fly? A giant ostrich, but they can't fly into the sky! This is not because their wings are useless, but because their feathers are too soft and their wings are too small to fly at all. In addition, the ostrich's muscles are underdeveloped and its sternum is flat, which is not conducive to flying.
Ostriches live in Africa. Because they have lived in desert areas for a long time, their bodies gradually evolved into what they are now in order to adapt to the environment. 9。
Why can't it go bad easily? Lunch meat, black bean shad, tomato sauce beans.
They are all delicious canned food, which can be preserved for a long time without deterioration. This is because the can is sealed, so bacteria can't enter.
When people make canned food, they pump all the air out of the canned food and then seal it. In the absence of air, even if the food inside is contaminated with a little bacteria, they can't survive or reproduce! 10。
Why do babies always cry at birth? Babies cry when they are born, not because they are unhappy, but because they are taking the first breath of air! When babies leave their mother's body and are born, the first breath of air will rush to their throats, violently impact the vocal cords, make them vibrate, and then make a sound similar to crying. 1 1。
Why do lizards keep playing backwards when their tails are broken? In order to protect themselves, many lizards also protect their eyes and ears; When some lizards are attacked, their tails will be broken due to the severe contraction of their muscles. Because there are still some nerves alive in the broken tail, it will keep bouncing, thus distracting the enemy and running away.
Don't think that their lives will end like this. In fact, it only takes a few months, and their tails will grow back and move on. 12。
Why is the squirrel's tail so big? Don't look at the relaxed mouse tail! When the squirrel jumps around the tree, its tail plays a great role. It can keep balance when the squirrel jumps to the tree to avoid falling and being injured.
In addition, this big tail can play a more protective role in winter, tightly surrounding the squirrel's body, which is convenient and practical. 13。
Why can't a person's thumb have one or three knots? The average person has five fingers, each with a different length. However, does anyone realize that besides the thumb, other fingers also have three sections, while the thumb alone has only two sections? It turns out that the number of joints is just the same as the other four fingers.
If it is three knots, the thumb will appear weak, so that it can't lift heavy objects; If there is only one section, it can't grasp things freely with the other four fingers! 14。 Why not tickle yourself? When others scratch ourselves, we will feel itchy and laugh constantly; However, when we scratch ourselves, we not only don't laugh, but also don't itch.
Based on our psychological preparation, the brain will send out a message that there is no danger, and the nerves will relax, so that they will not laugh and itch! 15。 Why is the sea mostly blue and green? Looking at the sea, it is often found that the sea water is blue-green.
However, when you pick up the sea water, you can only see it as transparent and colorless as old water. Original.

Air pollution mainly refers to the chemical pollution of the atmosphere.
There are many kinds of chemical pollutants in the atmosphere, and dozens of them are seriously harmful to human body. The air pollution in China belongs to coal-burning pollution, and the main pollutants are soot and sulfur dioxide, as well as nitrogen oxides and carbon monoxide.
These pollutants mainly enter the human body through the respiratory tract, and are directly transported from the blood to the whole body without detoxification of the liver. Therefore, the chemical pollution of the atmosphere is very harmful to human health.
This kind of harm can be divided into three types: chronic poisoning, acute poisoning and carcinogenesis. The concentration of chemical pollutants in the atmosphere of chronic poisoning is generally low, which mainly produces chronic toxic effects on human body.
Scientific research shows that chemical pollution in urban air is an important cause of chronic bronchitis, emphysema and bronchial asthma. Acute Poisoning When the factory emits a lot of harmful gases and there is no wind and fog, the chemical pollutants in the atmosphere are not easy to disperse, which will cause acute poisoning.
For example, in 196 1 year, three petrochemical enterprises in Niigata, Japan continuously discharged a large number of chemical pollutants such as sulfur dioxide, and windless weather caused asthma among local residents. Later, the local air pollution was controlled and the incidence of asthma decreased.
Carcinogenesis Among the chemical pollutants in the atmosphere, there are polycyclic aromatic hydrocarbons (such as 3,4-benzopyrene) and lead-containing compounds, among which 3,4-benzopyrene has the strongest effect on lung cancer. The smoke produced by burning coal, cars and cigarettes contains a lot of 3,4-benzopyrene.
Chemical pollutants in the atmosphere can also fall into water, soil and crops, and be absorbed and enriched by crops, thus endangering human health. Air pollution also includes biological pollution and radioactive pollution.
Biological pollutants in the atmosphere mainly include pathogenic bacteria, mold spores and pollen. Pathogens can make people suffer from infectious diseases such as tuberculosis, and mold spores and pollen can cause allergic reactions in some people.
Radioactive pollutants in the atmosphere mainly come from radioactive wastes from the atomic energy industry and medical X-ray sources, which are easy to cause skin cancer and leukemia. Improve immunity six times a day and have a good sleep: poor sleep is related to the decline of immune system function.
T cells in the body are responsible for dealing with viruses and tumors. If you don't get enough sleep, the number of T cells will decrease and the chance of getting sick will increase. You don't have to sleep for eight hours, and you wake up feeling refreshed in the morning.
Do some exercise: exercise for 30 to 45 minutes every day, the number of immune cells will increase and the resistance will increase relatively. However, if the exercise is too intense or lasts for more than 1 hour, the body will produce some hormones and inhibit the activity of the immune system.
Do * * *: * * to relax and reduce stress. 1 month for 45 minutes every day, the immune function will be significantly improved.
Daydreaming: Daydreaming for 5 minutes every day, taking a deep breath and daydreaming at the same time can increase the number and activity of immune cells. Take part in an art activity: Laughter can significantly increase interferon and make immune cells more active.
If you feel that you lack a sense of humor, you can watch more comedies and funny cartoons. Music can increase antibodies against infection and cancer. No matter what kind of music you like, you can have a healthy physiological reaction when you listen to it.
Communicate with your bosom friend once: people with many friends are not easy to catch a cold, and their immune function is better than those with withdrawn personality. Studies have shown that good social relations help to resist stress, reduce stress and affect immune cell function.
You should also pay attention to the method of heating in winter. When the cold current comes, some people will shiver and try their best to keep warm, but nine times out of ten methods are not advisable, such as excessive exercise heating. Doing more activities in winter can not only exercise, but also drive away the cold. However, for the elderly, we must do our best when exercising. Don't choose those sports with too much exercise, but choose jogging, cycling, playing Tai Ji Chuan and other sports with less exercise.
If symptoms such as dizziness, headache, weakness of limbs, chest tightness, shortness of breath, insomnia and dreaminess appear after exercise, it means that the amount of exercise is too large, so we should pay attention to reducing the amount of exercise and stop the exercise with particularly bad reaction in time. The method of dispelling cold and heating is out of order.
Because most elderly people are afraid of the cold, they like to lie down with a hot water bottle when sleeping, or let the electric blanket heat the bed to keep warm, which often causes skin erythema or burns. Generally, when the room temperature reaches 18-25 degrees Celsius, it is also a suitable temperature for the human body, and no other means are needed for heating. The sun is too long to keep warm.
When winter comes, some old people like to take their grandchildren and move a chair to the dam to bask in the sun to keep warm. This is a good thing. Proper sunbathing is beneficial to the absorption of calcium, but doctors remind that sunbathing has a certain degree. Too long time is harmful to the body, because it will damage the skin, destroy the natural barrier of the human body, and make harmful chemicals and microorganisms in the atmosphere invade the human body, causing infection and vision loss. In particular, the skin of infants and young children is delicate and cannot be directly exposed to direct light for a long time.
Sleeping with your head covered is harmful to your health. Some old people like to sleep with their heads covered in winter, thinking that it can be warmer. This way of sleeping is harmful to health.
On the other hand, due to the decrease of oxygen content in the bed, carbon dioxide and other waste gases gradually increase, which affects the normal breathing movement and even causes suffocation. Second, because of lack of oxygen in bed, cardiovascular and cerebrovascular diseases are easily induced.
1 Weather refers to meteorological phenomena that occur in a short time (from several minutes to several days), such as thunderstorm, hail, typhoon, cold wave and strong wind. 2. What is climate climate refers to the long-term average of various meteorological elements in a long period (month, season, year, year, even hundreds of years, etc.). ).
It is a comprehensive reflection of the basic characteristics of cold, warm, dry and wet weather conditions in a region. 3. Climate resources Climate resources refer to natural substances and energy widely existing in the atmosphere, such as light energy, heat energy, precipitation and wind energy. , can be directly or indirectly used by people, forming wealth, with use value. It is a very precious renewable natural resource and the basic condition for the survival and development of human society, and has been widely used in the national economy and people's livelihood.
