Do you have eye floaters? And what are floaters in the eye?
The official name of eye floaters is "turbid vitreous" or "vitreous floats", and you see black dots flying in front of you, just like the name given to mosquitoes. In addition, there is a beautiful name, "Cloud and Mist Covering Eyes", which is the conscious that there are misty black shadows flying and drifting in front of you, sometimes dim and sometimes clear. But whether there are black spots or shadows in front of you, beware of eye floaters. Eye floaters are generally more common in middle-aged and elderly people over 40, or young people with myopia, especially those with high myopia, and some patients after cataract surgery. Most eye floaters are natural manifestations of eye aging and are classified as common senile diseases. However, there are also many young people who stare at mobile phones and computers for a long time, leading to excessive eye use, high myopia, etc., and the vitreous body becomes liquefied and turbid, and they often feel dark shadows and blurred vision in front of them, and they are prematurely infected with senile disease. These conditions have undergone careful eye examination. If no significant organic disease related to them is found, then this type of eye floaters is physiological and generally does not require treatment. Physiological eye floaters are "good mosquitoes", as long as they maintain adequate rest and pay attention to eye hygiene, most of them can heal by themselves. However, there are still some "bad mosquitoes" that are difficult to heal on their own. They are pathological eye floaters and are the second blinding eye disease after cataracts. There are three characteristics in judging whether eye floaters are pathological: 1. Are there any abnormal flashes in the eyes? 2. Whether the number of flying mosquitoes is increasing in a short period of time. 3. Whether the line of sight is blocked. When the above situation occurs, you must go to the hospital and treat eye floaters in time, because pathological eye floaters are often accompanied by serious eye diseases, such as vitreous hemorrhage, retinal tears, and even retinal detachment. If you do not pay attention to it, treat the cause of the disease. Cause blindness. In addition, patients with high myopia above 600 degrees should be alert to eye floaters. The eyeballs of patients with high myopia are elongated and deformed, and the sudden appearance of "flying mosquitoes" is likely to be pathological. Read more

How to help family members with depression?
1. Communicate and interact with family members with depression 1) Recognize that depression in family members is not your problem. When they know that their family members are suffering from depression, some people feel that it has something to do with them. You know, it's not your fault. Depression makes it difficult to establish emotional connections with family members. 2) Treat depression as a real physical illness. As a family member, you have to understand that they are enduring a double torture both physically and mentally. It is generally easy for people to attribute the problems of depression patients to their actions. But realizing that this is not entirely their fault can make you support him even more. The support of family members with depression can help them recover from depression. 3) Provide support. The most valuable thing for the recovery of depression patients is the support of family members. You can take the initiative to ask him to talk about his feelings, don't judge him at this time. 4) Question guidance. When helping a family member with depression, you need to know his current state in time. Because depression may cause a series of problems, self-abuse, and even suicide. Guide family members to think about why they feel depressed, such as asking: When did it start to feel bad? What makes you feel bad? What makes you feel better? See more Pterygium is a common and frequently-occurring disease in ophthalmology. It is called "pterygium panning eye" in traditional Chinese medicine, and it is commonly called "fish meat". It is generally believed that it is a chronic inflammatory disease caused by external stimuli. It is a victim of one or both eyes. It is named because its shape resembles the wings of an insect. It is a kind of neoplastic tissue on the bulbar conjunctiva and cornea of the palpebral fissure, which gradually increases after invading the cornea, and can even cover the pupil area and seriously affect vision. It is the degeneration, hypertrophy, and hyperplasia of the bulbar conjunctiva and subconjunctival tissues of the palpebral fissure, which develop into the cornea and appear triangular. It is more common in outdoor workers, and fishermen and farmers have the most disease. It may be related to long-term chronic irritation such as wind, sunlight, and smoke. Pterygium is generally more common in the large corner of the eye, and sometimes it can grow on the cornea, blocking the pupil and reducing vision. How is pterygium formed? Its cause is still unclear. It is generally believed that the disease is related to long-term field work, exposure to sand, dust, cold, heat and sunlight. At the same time, overwork, lack of sleep and chronic inflammation of the conjunctiva are also predisposing factors. In recent years, it has also been believed that the pterygium is closely related to the overdevelopment of the control ligament of the medial rectus muscle and genetic factors.
Prevention of pterygium is mainly to avoid smoke, dust and sun stimulation as much as possible, pay attention to eye hygiene, the occurrence of pterygium is closely related to the damage of ultraviolet rays, and outdoor workers or favorites who are exposed to ultraviolet rays and the glare and reflection of strong light for a long time For people who are outdoors, wearing anti-UV glasses has a certain preventive effect. Suffering from trachoma or other types of conjunctivitis should be treated promptly, and at the same time, you should pay attention to adequate sleep, regular life, and avoid dry stools and other systemic adjustments. The pterygium can be divided into three parts in terms of its shape: it grows on the cornea and is the tip of the pterygium, called the head. It is fanned back and slightly raised. The neck is located at the junction of the cornea and conjunctiva. The broad part that stretches to the surface of the conjunctiva is called the body, and there are many new blood vessels on it. Pterygium can be divided into the following two types: (1) Progressive type: The pterygium has a wide neck, many new blood vessels, hyperemia, and hypertrophy. The body is triangular and stretches to both sides. The head is obviously raised, growing into the surface of the cornea, and even blocking the pupils. (2) Static type: The pterygium stops when it grows to the limbus. It is not hyperemic, is reddish, has a flat head, and a thin neck and body. It is in a relatively static state, but does not go away on its own. In addition, there is a kind of pseudo-pterygium, which can grow on any part of the limbus. It is generally small and gray-white on the surface, but there are also thicker ones. Scar tissue is often formed due to trauma, corneal edge ulcers, chemical or thermal burns of the conjunctiva, and generally no longer grows after formation. It is completely different from the previous two types of pterygium in nature. There are two commonly used methods for the prevention and treatment of pterygium: (1) Drug treatment, for the static type, the pterygium does not invade the cornea and does not affect the vision, so treatment is not necessary. Patients with trachoma or chronic conjunctivitis can be treated with antibiotics or glucocorticoid eye drops. (2) Those who have progressive pterygium or pterygium growth into the cornea that affect vision should go to the hospital for pterygium resection. After pterygium surgery is performed according to traditional methods, the recurrence rate is higher, about 30%-40%. The stimulation of the operation causes the chemotaxis and aggregation of polymorphonuclear leukocytes (they can release vascular growth factors), which is the cause of neovascularization and recurrence after surgery. Due to the high incidence of pterygium and the high recurrence rate after traditional surgical methods, the world ophthalmology community has conducted in-depth research on this operation, and continuously improved and perfected the surgical method. Pterygium removal under a microscope and auto-conjunctival flap transfer or limbal stem cell transplantation are commonly used. The pterygium is completely removed during the operation and the corneal surface at the resection site is smoothed. Because as long as the cornea is smooth and there is no small cornea, there will be no tear pool and tear retention, and the recurrence factors will be reduced to a minimum. At the same time, self-conjunctival transplantation eliminates the stimulating factors that produce new blood vessels, thereby preventing the recurrence of pterygium. In addition, the use of mitomycin eye drops after surgery can inhibit the proliferation of DNA and fibroblasts, and can also prevent the recurrence of pterygium. Six characteristics of brain aging
1. Decreased visual spatial ability. People's recognition and spatial positioning of objects in the three-dimensional world belong to the visual space ability. The decline of visual space ability can cause people to have obstacles in direction judgment, such as getting lost, unable to distinguish the direction, not knowing which building and unit of their home is; when taking a car, they will take one more stop or one less stop. 2. Decreased language ability. Language skills mainly include listening, speaking, reading, writing, naming and paraphrasing abilities. When language ability declines, people not only become unresponsive, but they also experience deviations in understanding or barriers in expression. Sometimes, they only use the language they remember. For example, the elderly may suddenly not remember what the elevator says, and can only be described as "something that can go up and down." Or when others talk about taking an elevator, the elderly cannot understand what an elevator is. Once the decline in language ability has an impact on life, it is necessary to go to the hospital for examination in time. 3. Ability to control emotions. Under normal circumstances, people can better control their emotions. When the emotional control ability is hindered, it will show indifference, loss of interest in other things, irritability, and emotional instability. 4. Decline in execution ability. Including the ability of planning, organization, decision-making and execution, and can simplify the environment and improve work efficiency. When the execution ability declines, it is often impossible to complete multiple tasks. You can only do one thing one at a time, or even one thing cannot be done well. 5. Decreased concentration. It is not too difficult to concentrate at work, but as people get older, some people will have difficulty concentrating. For example, when others are talking, they become unconsciously distracted. This is a manifestation of decreased concentration. 6. Poor memory. Deteriorating memory is the mantra of many people, and this is also the most obvious and easiest manifestation of dementia. If you keep repeating an action or saying the same sentence, you always think that you are going to wash the dishes after eating. The performance of these memory loss may affect people's normal life. Five factors of brain aging 1. Diabetes: Diabetes can harden and occlude brain capillaries and increase blood viscosity. The brain is in a state of ischemia and hypoxia for a long time and ages faster than ordinary people. Hypertension, atherosclerosis, etc. can also accelerate brain aging. 2. Smoking: When smoking, the nicotine in cigarettes can reach the brain within 10 seconds of inhalation, and remain active within 20-40 minutes. Nicotine can damage blood vessel walls, promote arteriosclerosis, reduce brain oxygen supply, impair logical thinking, and accelerate The brain is aging. A study in the United States showed that smoking a pack of cigarettes reduces life by 2.3 hours. 3. Air pollution: The brain is the organ that consumes the most oxygen in the whole body, consuming 500 to 600 liters of oxygen per minute on average. There is not enough oxygen in the polluted air to support the work of the brain. It also contains harmful substances such as nitrogen oxides and carbon monoxide, which enter the brain through breathing, causing memory decline or depression, and accelerating the cognitive decline of adults. 4. Overeating: After overeating, the human body tends to mobilize a large amount of blood and energy to the digestive system in order to digest too much food. The energy supply of the brain is reduced, and the brain is in an ischemic state, which will damage the brain cells. 5. Habits to stay up late: Irregular life affects the body's normal biological clock and metabolism, and brain function is disrupted. Staying up late will make the brain in a state of excitement, and the delay in getting a rest makes the brain not fully repaired and damages the brain's neuronal cells. British research found that irregular rest and frequent night shifts can impair the cognitive ability of the brain. Nowadays, there are more and more people with high blood pressure, and many people do not know the arrangement of high blood pressure good very well. Food is very important to control high blood pressure, so it is necessary to arrange daily food reasonably. Today, let me introduce to you how the food for high blood pressure should be arranged best.
Dietary principles for high blood pressure If hypertensive patients often eat the liver, brain, heart and other parts of animals, it will increase the cholesterol content in the patient's body and accelerate arteriosclerosis. Reduce salt intake. According to research by clinical experts, salt is a high-risk substance that causes high blood pressure in people of different ages. The relationship between salt and hypertension has been confirmed by many experts, especially middle-aged and elderly people, most of whom are salt-sensitive, and should be less salt. The food should be light. It is recommended that vegetarian food is the mainstay, and the vegetarian way reduces the blood pressure of hypertensive patients. Therefore, patients with high blood pressure should have a light food, high vitamin, high fiber, high calcium, low blood sugar, and low blood sugar food. If patients with high blood pressure often smoke and drink alcohol, too much alcohol and tobacco may lead to myocardial infarction and stroke, with disastrous consequences. Eat a regular diet: do three meals a day and eat regularly, not to be too thirsty or over-satisfied, and not to overeating. Next, let's take a look at what foods are suitable for hypertensive patients. What to eat for high blood pressure eggplant. Eggplant is also a food that people often eat. Eggplant contains bioflavonoids (vitamin P), which can reduce capillary fragility, prevent bleeding, lower blood cholesterol concentration and lower blood pressure. It has an adjuvant therapeutic effect on patients with high blood pressure, arteriosclerosis, hemoptysis, and purpura. Antihypertensive tea. Nutrient-rich and rich in a variety of vitamins and minerals, amino acids, residues and glucose and plant fiber. Alpine green tea is a good functional food. It can lower blood pressure, lower fat, anti-aging, increase endurance, lower cholesterol, and inhibit small amounts of accumulation. Inhibit thrombus formation, inhibit the reproduction of harmful bacteria in the intestines, and inhibit the formation of harmful oxides. The most prominent function is to lower the three highs, high blood pressure, high blood lipids, and high blood sugar. potato. Eating more things containing calcium and potassium will greatly help lower blood pressure, and potatoes have a lot of calcium and potassium. Keep the heart muscle healthy. celery. Celery has a good effect on lowering blood pressure. This is because celery contains bioflavonoids (vitamin P), which can reduce the permeability of capillaries, thereby lowering blood pressure. Urticaria is the name of modern medicine. Food, drugs, infections, inhalants, physical factors and even mental factors are closely related to the occurrence of urticaria. Modern medicine believes that its pathogenesis is the activation of mast cells to release histamine and other inflammatory mediators to cause blood vessels dilation and increased vascular permeability lead to dermal edema.
In traditional Chinese medicine, "addiction rash", "ghost wind lump", "rubella block", and "red white travel wind" all belong to the category of urticaria. Urticaria is a common recurring skin and mucosal allergic disease. According to statistics, 15%~25% Of people have it happened at least once in their lives. Modern medicine treatment of urticaria has problems such as low cure rate, poor long-term efficacy, drug resistance or dependence, and heavy economic burden. At present, the traditional Chinese medicine treatment of urticaria mostly adopts the methods of promoting blood circulation, dispelling wind, extinguishing wind, clearing heat, and detoxifying, etc., and the clinical effect is good. Pathogenesis 1. Liver Modern Chinese medicine's understanding of the etiology and pathogenesis of urticaria inherits the main point of view of ancient physicians, that is to say, the main condition is still the actions of "wind evil". Of course, the "wind evil" here includes both induced external wind evil. It also includes endogenous wind evil. The liver is belong to the wind, and the wind plays an important role in the occurrence and development of urticaria. At the same time, disharmony of Qi and blood is the basic pathogenesis of urticaria, and the liver plays an important role in reconciling Qi and blood. First of all, the liver regulates the Qi machine and emotions; the liver also stores blood and regulates venting. Modern people are prone to emotional stress, anxiety and depression due to heavy life and work pressures. Liver depression loses its ability to regulate the body's Qi for a long time, and then there is a loss of Qi and blood, so the incidence of urticaria is also increasing. 2. Spleen and stomach Although the occurrence of urticaria is related to external physical and chemical factors, the internal environment of the body is the key, and the existence of deficiency, phlegm, and blood stasis is the top priority. The spleen and stomach are the foundation of acquired nature, the source of energy and blood producing. Acquired deficiency of the spleen and stomach, lack of Qi and blood producing, resulting in insufficient Qi and blood, the lack of qi deficiency and external protection can easily cause external wind to attack the skin and stay on the skin, blood deficiency can not nourish the skin, and blood deficiency is prone to wind, and there will be wind masses and itching The spleen and stomach coexist in the middle Jiao, and govern the movement and transformation. If the spleen Qi is insufficiency, the water and food or water dampness will not be normalized, and it will easily lead to turbid phlegm, dampness and turbidity in the skin, or in conjunction with the wind, is accumulated in the skin, and developing an urticaria. At the same time, a considerable part of patients with urticaria due to long-term skin itching, restless sleep and eating, and excessive worrying, eventually lead to spleen deficiency and food loss, and then aggravate the disease or frequent attacks, that is, the onset and the disease are closely related to the spleen deficiency. Chinese medicine has also achieved good clinical effects in the treatment of urticaria based on the principle of regulating the spleen and stomach, which further proves that the onset of urticaria is related to the spleen and stomach. 3. Lung The lung governs the Qi and the breath, and the skin and fur in the body, and the surface of the body. Exogenous feelings dominated by wind evil can cause urticaria. The lungs dominate the skin, the lungs are weak and the Qi is not strong, and the wind is attacking the surface. The discord between the Qi and blood is an important cause of urticaria: the lungs are not strong, the wind-cold or wind-heat evil beats the skin, or spreads to the lungs. Other internal organs cause acute urticaria due to the imbalance between the Qi and blood. Chronic urticaria is usually due to the long course of the disease, both Qi and Yin are injured, the deficiency of Qi and the body are not strong and easy to be invaded by evil, the deficiency of Yin and blood are dry and the wind will eventually lead to internal and external harmony. Seek in the same way, it will happen when encountering cold, encountering heat or encountering labor. 4. Kidney The onset of urticaria is generally based on congenital physical factors, induced by wind, cold, dampness, heat, or careless eating, or internal injuries of seven emotions. The kidney is "the foundation of the innate", which contains the inner Yin and Yang, which is the foundation of Yin and Yang. Chronic urticaria occurs repeatedly and does not heal for a long time. Eventually, it will damage the body's Yin, essence and blood, causing kidney Yin deficiency, and further development may cause both Yin and Yang to be damaged. Traditional Chinese medicine believes that the kidney is the "base of the viscera, the root of the twelve meridians, the base of breathing, and the source of the triple Jiao". Therefore, some scholars have proposed that intractable and refractory chronic urticaria is closely related to kidney deficiency, so when it comes to treatment the relationship between kidney Yin and kidney Yang, should be carefully observed to maintain the dynamic balance between the two. Modern medicine believes that certain types of urticaria, such as hereditary familial urticaria syndrome, familial cold urticaria, delayed familial, and localized hot urticaria, are related to genetic factors. This coincides to some extent with the kidney being the innate foundation. Dialectical typing: 1. Wind-cold type The color of the wind group is pale red or pale, which occurs on the exposed parts of the head, face, hands, feet, etc. The skin lesions increase after exposure to wind and cold, and the temperature is slow, and the winter is heavy and the summer is light; the tongue is fat and pale, the coating is white, and the pulse is floating tight or slow. . It is suitable to expel wind and cold, reconcile Qi and blood, and use Jing Fang Bai Du Cao powder to add and subtract. 2. Wind-heat type The onset is rapid, the wind group is red and burning, and if it is hot, it is accompanied by fever and sore throat; the tongue is red, the coating is thin and yellow, and the pulse is floating. Sang Ju soup is used as a prescription. 3. Blood heat type First feel the skin burning and itching, immediately after scratching, there will be wind masses or streaks bulging, more and more scratches, especially at night, upset and restless when rash occurs, dry mouth thinking about drinking; red tongue, thin yellow coating, pulse thready and rapid. The prescription should be used to clear heat and cool blood, eliminate wind and relieve itching, and use Xiao Feng power to add or subtract. 4. Spleen deficiency type The wind is unhealed, accompanied by cold form, cold limbs, nausea, abdominal pain and diarrhea; pale tongue, white coating, deep and moderate pulse. It is suitable for the prescriptions are Fu Zi Li Zhong soup and Gui Zhi soup. 5. Blood deficiency type The wind group recurs and persists for a long time, and it occurs more often in the afternoon or night, or worsens when tired; the tongue is red, less fluid or weak in texture, and the pulse is deep and thready. For the treatment of nourishing yin and nourishing blood, evacuation of wind evil, the addition and subtraction of Dang Gui Yin Zi is used. Modern medicine is basically developing continuously along the thinking method of reductionism. Reductionists believe that life phenomena and their dynamic processes can be reduced to physical and chemical molecular motion processes. Therefore, with the development of human society, science and technology are deepening in two directions, on the one hand to a more macroscopic universe, and on the other hand to a more microscopic world. The development of biomedicine has moved to the level of cells, genes, protein molecules, and even small chemical molecules. Therefore, the continuous development of medicine will inevitably lead to more and more detailed divisions. This is also the basic result of following reductionism.
