Remind II: appropriate movement

Heart disease is an important reason there is a lack of exercise. In the same living environment, often sitting motionless, and suffering from coronary heart disease than the regular activities 2 times higher.

Movement of the Heart What are the advantages? Movement can promote the heart of the small blood vessels to expand, extend, increase, improve myocardial oxygen supply situation, to improve blood lipid metabolism. Sports also help to improve myocardial metabolism and improve the working abilities of myocardial metabolism and cardiac function. In addition, can improve blood fibrinolytic activity, to prevent the hemagglutinin too high, to prevent and retard atherosclerosis development helpful.

Symptoms of heart disease

Diagnosis of the disease symptoms are often the precursor. The same was true of heart disease, the patient's feeling, but also provides physicians with an important clue. However, in real life, some irrelevant symptoms linked with heart disease is common thing. Many people think that is the heart palpitations. In fact, despite the heart palpitations but it is a healthy and sound of. Therefore, the symptoms of heart disease to make it clear that to arouse people's attention and the elimination of unnecessary uncertainty is necessary.
Fatigue: It is often a variety of heart disease symptoms. When the heart so that poor blood circulation, metabolic wastes (mainly lactic acid) can accumulate in the tissues and stimulate peripheral nerves, cause fatigue. Fatigue can be re-light, light can not care, could impede the work of the heaviest. However, there is no specificity of heart disease fatigue, it and other diseases caused by the difficulty of distinguishing between fatigue.
Pain: myocarditis, pericarditis, arrhythmia patients may feel chest pain. The most common is angina. Angina often tired, excited, a meal for the incentive sudden attack, chest pain and more in the middle, there is oppression, burning or squeezing flu, and even a sense of dying of suffocation, and some may Bleeding in the left shoulder, back and medial left upper arm. Pain in the short duration of the disappearance of 3-5 minutes, the longest not more than 20 minutes.
Shortness of breath: shortness of breath are common symptoms of heart disease. The most significant feature of exertional shortness of breath and paroxysmal nocturnal dyspnea. Labor is shortness of breath shortness of breath with activity. Heart disease often say, I am on the second floor have palpitation, breath, can not stand; paroxysmal nocturnal dyspnea sleep at night that is uneven, and sometimes hold up from a dream, and sit a while in order to ease breathing.
Cyanosis: skin and mucous membrane, antihelix around the nose and lips weeks purple fingers.
Edema: the body or lower extremity edema, and sometimes appeared stagnant water in the chest or abdominal cavity.
Palpitation: Patients often feel palpitations, especially in activities beyond. However, in the heart or other diseases may also occur when the disease, the diagnosis of heart palpitations of little significance

basic structure of the heart

The heart is located in the chest cavity, above the diaphragm, the second between the lung, about two-thirds of the left in the middle lane. If a reversal of the heart, and before and after the cone a little flat. Apical blunt yen, towards the bottom left, and the chest wall adjacent to, and its surface projection in the left chest wall fifth medial clavicular midline 1-2cm Department, so here we can see or touch the apex beat. Wide bottom of my heart, there are large blood vessels resulting from North Korea right after the top, with the esophagus and other organs after mediastinal adjacent.

The heart of the surface near the bottom of my heart Department, there are cross-bit almost a week around the heart, just in front of aorta and pulmonary artery was the beginning of the Department of the interruption. Groove above the left and right atrium, ditch Following the left and right ventricle. In front of and after the ventricle (lower) have a vertical surface of the shallow, extended by the apex slightly to the right, respectively, before and after the chamber said sulcus, for the left and right ventricular surface boundaries. The left atrium, left ventricular and right atrium and right ventricle of normal relations between the location of mild from right to left to reverse the phenomenon, that is, tend to front the top of the right heart, left the bottom of the left ventricular biased.

The heart is a hollow muscular organ with a four-chamber: After the upper part of the left atrium, right atrium, atrial septum between the two are separated; before the lower part for the left ventricle, right ventricle, the two intervals to ventricular septal. Under normal circumstances, because of room, ventricular septal separation, left heart and right heart does not directly transport, but each atrial Atrioventricular I may be leading to the ipsilateral ventricle.

Thin-walled right atrium. According to the direction of blood flow, right atrium has three entrances, one exit. Entrance that is on the inferior vena cava and coronary sinus mouth mouth. Ostium of coronary venous blood for the heart wall of the main entrance. Exit right atrioventricular mouth, right atrium with its pass to the right ventricle. After the lower part of atrial septal oval oval depression, said Waterloo for embryonic period connectivity left and right atrium of the foramen ovale ruins after atresia. Right atrium to the left before striking the upper part of that right atrial appendage.

Different from the right ventricle 2, the entrance that is the right atrioventricular mouth, and its peripheral shaped leaves with three valves, said the right atrioventricular valve (that is, the tricuspid valve). By location, respectively, said before the valve, after the valve, valve septum. Vertical valve chamber, and by many lines kind of tendons and ventricular papillary muscle connected walls. Pulmonic said exports, and its peripheral valve has three half-moon, said the pulmonary valve.

Left atrium constitute the majority of the bottom of my heart, there are four entrances, one exit. In the left atrial posterior wall of both sides, each with a pair of pulmonary vein for pulmonary vein around the entrance; the left atrium of the former under the left atrioventricular mouth, leading to left ventricle. The front of the left atrium to the right before the salient parts of the left atrial appendage said.

Left ventricular discrepancy 2. That is, the entrance of the left atrioventricular mouth with peripheral left atrioventricular valve (mitral), by location, said before the valve, after the valve, they are tendons, respectively, with the former, the latter linked to papillary muscles. Export-aortic mouth, is located in the front left atrioventricular mouth above the margin of the aortic valve with a half-moon.

The symptoms of chronic pharyngitis

The symptoms of chronic pharyngitis
Pharynx can have all kinds of feeling unwell, such as foreign body sensation, itching, burning, dry, micro-pain, dry cough, cough difficult net, speech fatigue, mouthwash or brushing their teeth, speech, nausea and vomiting for a long time easy.
Sore throat treatment method:
1. I take tablets, especially the mouth of phenol tablet surface can kill bacteria, help control the invasion, with a more modest role in anesthesia can be paralysis nerve endings to reduce pain, the spray liquid phenol have the same effect
2. I take zinc tablets, which can effectively relieve sore throat, but not for the use of high doses of zinc up more than seven days to avoid interference with other minerals in the body
3. Wash saline solution or other treatment, such as chamomile tea, lemon juice, whiskey, if the voices are hoarse or coughing, then the deeper parts of the pain, then rinse saline than useless
4. To increase the indoor humidity, not only mouth breathing and inhalation of dry air, causing pain
5. To solve the problem of nasal obstruction can reduce the problem of sore throat
6. Taking painkillers to relieve pain
7. Drink boiled water
8. Chamomile soak into the boiling water, then hot towel soaked dry screw directly deposited in the affected area to be cooling towel to repeat the aforementioned moves, which will help to ease discomfort
9. Taking capsules, to be effective disinfection, the only counter-productive should immediately stop using
10. Taking vitamin C, will help strengthen the organization, can help fight sore throat bacteria
11. Replacement toothbrush, an old toothbrush to prevent bacterial invasion, if the sick, the recovery should change a toothbrush to avoid being infected with

Eye diseases first aid

The eyes are the window of our psychological, so we have to crack the Prevention of Cruelty to. Teach you the following first-aid methods of eyes: If you suspect head injury, foreign bodies embedded in the eye or chemicals splash into the eyes, should call the emergency phone.
If the eye with blood, the application of clean cloth to cover the eyes, and bring patients to the hospital.
If the eyes are active bleeding, should raise the patient's head position so that it is higher than the heart, with a clean cloth to cover their eyes and took him to a nearby hospital.
NOTE: If you suspect head, neck, back injury, not to move patients, emergency phone call.
Symptoms: eye injury or break, the eyes can not be opened, around the eyes or eye pain, light allergy, eyes bleeding, visually impaired, the eyes dry, itching, headaches, tears, ranging from bilateral pupil large, fast frequency chemicals splash into the eyes blink
Note: do not waste any time, immediately wash with water eyes, and to ensure that there is water below the double-eyelid to enter. Do not use anything other than dealing with the eyes. Do not let patients rub their eyes.
1, eye wash with water. If you can not find the tap, you can use cup of water rinse eyes for 15 minutes, and to ensure that water entering the eye angle. Wash the eyes, so who opened his eyes and the flow of water washed at least 15 minutes, and water before entering the eye, and then out of the eyes. If the eyes damaged water rinse eyes.
2, if the patients to wear contact lenses should we let him off.
3, suffering from eye coverage. After washing with a clean cotton cloth covering of the eye disease, and covered his eyes bandaged in order to reduce the risk of eye activity. If possible, should be to identify the chemical burns the eyes, or at least should tell their doctor chemicals are wet or dry.
Foreign Bodies:
Note: Do not try to be embedded in the eyes of foreign bodies removed. If a larger foreign body, such as pens, used in a paper cup on the open a hole and put it in the eye to boosting the foreign body, and fixed cups. With cloth to cover the other eye in order to avoid suffering from eye movement. If the foreign body in the smaller, and with a cloth to cover his eyes and less fixed.

Structure of the eye

Approximate spherical eyes, is located within the orbit. Normal adult of its average diameter 24mm, down an average diameter of 23mm. The most prominent in orbit outside the front of 12 - 14mm, by eyelid protection. Including the eye wall of the eyeball, eye cavity and contents, nerves, blood vessels and other organizations.

1. Eyeball wall divided into outer, middle and inside the three-tier.

Outer layer from the cornea, sclera composition. The former 1 / 6 for the transparent cornea, and the remaining 5 / 6 for the white sclera, commonly known as "white." The outer eye to maintain eye shape and eye protection organizations. Cornea is to accept the entrance of the information the most outposts. Cornea is a transparent eyeball anterior part of the light into the eye after this. Cornea is slightly oval-shaped, slightly forward process. Diameter for the 11.5-12mm, vertical diameter of about 10.5-11mm. Thick around 1mm, the central government as 0.6mm. Pre-corneal tear film layer of the cornea to prevent drying, and maintain smooth and optical characteristics of the cornea role. Cornea is rich in nerves, astute. So the cornea is not only light to enter the eye and refracted image of the main structure, but also to protect the role and determination of the human body is an important part of perception. Sclera for dense collagen fiber structure, opaque, showing white, resilient texture.

Middle, also known as uveal, pigment membrane, is rich in pigment and blood vessels, including the iris, ciliary body and choroidal three parts.
Iris: ring was round, the most in uveal the first part, located in Crystal ago, said fold radial texture, with uneven surface recess. People of different races in different colors of the iris. Central has a 2.5-4mm of the hole, said the pupil. Ciliary body before then iris root, followed by choroidal, lateral to the sclera, the medial suspensory ligament through the Department of the equator and Crystal connected. Choroidal located between the sclera and retina. Choroidal blood circulation nutrition outer retina, which contains a wealth of pigment from the role of shading darkroom.
Inner retina is a layer of transparent film, is also a form of visual nerves the first leg of the transmission of information. Has a very sophisticated network architecture and extensive metabolic and physiological functions. Retina is to finish as the axis for macular foveal. Macula is the retina most sensitive visual special region, a diameter of about 1-3mm, the central government as a small concave, or foveal. Macular nasal Department about 3mm a diameter of 1.5mm red light district, for the optic disc, also known as the optic nerve is pooled retina visual fiber transmission backbone to the visual parts of the eye, no photoreceptor cells, it appeared for the vision inherent in the dark zone, saying that the physiological blind spot.

Knee pain

In fact, knee pain is a common phenomenon. Studies have shown that there are many factors resulting in women than in men more vulnerable to knee injuries.
To prevent knee problems (or recover from a knee injury) is the best way to maintain a healthy weight and strengthen knee muscles balanced reflection of the flexibility and adjustment, which can make less knee injury.
Women the most common cause of knee pain is the anterior cruciate ligament excessive stretching or tearing. Anterior cruciate ligament from the thigh into the back of the tibia in front of a short rope belt-shaped connective tissue. It prevents knee hyperextension and excessive rotation, so as to stabilize the knee. In most fitness process, the female anterior cruciate ligament injuries than the highest probability of more than twice as many men. In such as downhill skiing and gymnastics training for a class of movement, women than men vulnerable probability is increased to 8 times.
Like other types of knee injuries, the anterior cruciate ligament tear can cause obvious pain. Because the knee is the basis of our activities, so a direct impact on knee pain in people's quality of life.
Why is it that women's knees less vulnerable to damage it? In this regard, the medical profession vary. Some experts think that there may be anatomical differences caused. Women have wider hips, which has increased the pressure on the medial knee. Also the theory that estrogen and other female hormones can cause knee laxity or loose and therefore more unstable knee. There are statistics: Female athletes in the mid-point of the menstrual cycle, which is the highest level of estrogen, we will suffer more knee pain.
Another possible reason is that women in the running or doing other sports more often than men used to maintain the upper vertical position, this position makes biceps femoris not get enough stretching, thereby affecting the contraction of muscles and fat force, resulting in increased strength of quadriceps femoris dominate the situation. Running the greater the range of bending the knee, hip-led biceps femoris its greater range of movement, will be able to knee ligament and the surrounding bring more protection.
The prevention of knee problems and knee injuries to make the best way to recover is to keep a healthy weight and attention to the development of the body's flexibility and balance training and conditioning the muscles of the knee function will be less susceptible to knee injuries. The following exercises can strengthen these muscles.
Medial leg give
Start position: the left side of the body lying on the floor, hips slightly forward, right hip is at the top of the left hip. Left leg straight, natural flat on the floor. Peg-leg right knee, the inside of his right foot on the body near the floor. Head resting on his left elbow flexor and left big arm. Rotary right hand chest floor to support the body.
Action process: other parts of the body to maintain a smooth static, contraction of the inner left thigh muscle on the elevation to about 15 centimeters. Maintain the 3 seconds, and then slow to restore. Target number of one of his legs after the completion of a leg to do for another. Do 2 to 3 groups, each 15 times, alternating legs about to do.
Raise the degree of difficulty of the method: When the leg in action when the highest upward leg 4 to 8 times (do not fall), and then restored, then the next action.
Straight leg lift to adequate
Start position: sitting on the floor, his left leg straight in front of the body, toes up, his right foot flat on the floor, bending his right leg. Keep straight trunk and abdominal contraction, the body tilted backwards, hands in the post-up and focus on the forearm. Gently reminded by the left toes outward hip rotation, so toes point to dial on the 11 o'clock direction (right leg to do action, the location of his right foot to 1:00 direction).
Action process: tension left quadriceps and lifted his left leg and right knee until the same high. Hold the position for 3 seconds, and then gradually revert to the starting position. After all the number of his left leg after his right leg for doing this as a group. Do 2 groups, each 15 times.
Raise the degree of difficulty of the method: when the body upright exercise, to hold fast to his right knee in the chest.
Knee extension
Start position: sitting on the floor with his legs before平伸in vivo, and two towels rolled up, a pressure of a stacked in the left below-knee. Keep torso straight, crosstraining, freeclimber backward tilt the body and the body with a forearm support.
Action process: the left foot back up, the left quadriceps muscle tension so that the legs straight, knees pressure to force a towel, so that left the floor a little ankle. Maintain the 2 seconds, then relax. The number of his left leg after his right leg for doing this as a Group 1. Do 2 groups, each 15 times.
Raise the degree of difficulty of the method: Practice will be another leg up in the practice of ankle Department legs.
Leg-ju
Start position: lie face down in the Leg cite machine, elbow pad on his arm. Gently hold the handle, slightly down resumption jaw, crosstraining, freeclimber, back straight.
Action process: Bend your legs up so near the ankle to hip. When bending the knee to 90 degrees when the stop, when the calf and more or less vertical floor, and then restore. To do with middle-weight group 1, 15 times; and then use the upper-middle weight so Group 1, 12 ~ 15 times.
One-leg balance

Treatment of myopia

Surgical treatment

At present, there are excimer laser (PRK), radial keratotomy (RK) and other posterior scleral reinforcement, not suitable for under 18 years of age, the degree of young people are not stable.

Drops of eye drops

We often see all kinds of "governance syrup drop short-sightedness" of advertising, which is the main component of atropine after the horse.

Expert advice: atropine eye drops after the horse through the ciliary muscle relaxation, so that a flat lens diopter reduced, so that can be treated precisely as a result of ciliary muscle spasm sustained contraction caused by changing convex lens, such as changes in dioptre increase will pseudo-myopia corrected to address the state, but its true myopia treatment has no effect. But also in quality syrup uncertain circumstances, not the best.

Orthokeratology (ok mirror) in the treatment of myopia
Orthokeratology technology (orthokeratology) is gradually developed in recent decades a non-surgical method for treatment of myopia by wearing rigid gas permeable contact lens (RGP) to increase the radius of curvature of the cornea surface to reduce the corneal refractive. With the upgrading of RGP lenses, and its safety, effectiveness and rapid further enhanced.

Advantages: the night to wear during the day and pick a mirror, sports will not be affected; appearance; can be corrected is less than 300 degrees of myopia, astigmatism less than 150 degrees; for people over the age of 7 to wear, the age limit for less.

Expert advice: This treatment is not mature. OK mirror in a short period of time can not wear glasses; lens cleaning and ease of loading and unloading with the soft contact lens; belts early keratitis occur often.

A variety of therapeutic apparatus

Market in recent years the treatment of many types of apparatus, its design principle nothing more than to relax the application of regulation or in some way to stimulate the eye in order to improve the ciliary muscle function.

Expert advice: Instrument design has reached the intended target, and there is no objective basis for measuring the effect in time for the standards are based on visual acuity, and the impact of visual inspection of many factors, such as the eyes open and eyes closed, hard to regulate and arbitrary regulation, such as and so can cause changes in vision, therefore, there is no objective and accurate assessment of an instrument approach the actual results.

Methods of eye protection

Methods of eye protection

1. The eyes and the distance between the computer screen should be 60 centimeters
2. The computer screen below eye height to the height of about 25-30 degrees lower than the eye
3. The computer screen brightness to the appropriate, high-definition
4. Indoor relatively dark lighting, it should open bright fluorescent
5. Do not look at the computer when the "eyes" and to keep eyes blink at least every minute to ensure that more than 4-5
6. To minimize the use of contact lenses, but should wear spectacles
7. For about 1 hour to operate a computer and need to rest for about 10 minutes, look away
8. Rest of the time, attention should be paid to the activities of the activities of the neck and shoulder muscles, as stiff neck muscles can also affect the eye sight
9. Be careful not to lack of oxygen, maintaining good ventilation (especially the doors and windows closed in winter, it is necessary to pay attention to dozens of minutes every other month would have to open the doors and windows and outdoor exchange of a fresh air)
10. Attention to add water frequently, do not let indoor too dry (may be placed in indoor pot of water)
11. Eat more fresh vegetables, fruits, fish, dairy products and other foods rich in vitamin
12. Do more physical exercise

Pneumonia treatment

Pneumonia refers to lung inflammation in real terms, the pulmonary capillary congestion, edema, alveolar fibrin exudation and cellular infiltration, and even pulmonary pathological changes such as real change. The most common cause is infection, physical, chemical and allergies and so on. Daily stresses of pneumonia mainly refers to bacterial infections caused by pneumonia, this pneumonia is also one of the most common.
In recent years, domestic use of the treatment of immune agents viral pneumonia, such as the specificity of horse serum treatment of adenovirus pneumonia, without the merger of early infection better efficacy. (interferons) can inhibit the replication of HIV cells and enhance macrophage phagocytic capacity, the treatment of viral pneumonia have a certain effect.
Using whey liquid aerosol inhalation treatment agent syncytial virus pneumonia, shorten the course of treatment to relieve symptoms are - setting role.
Symptomatic treatment
Cough has phlegm, and not to abuse antitussive agents, due to the detriment of expectoration cough suppression. In order to avoid obstruction of bronchial sputum may make use of expectorant agents such as licorice compound mixture, 10% Chloride solution, ipecac syrup, cough syrup, such as the enemy.
Viscous sputum can be used n-chymotrypsin 5mg saline plus 15 ~ 20ml supersonic aerosol, can also be used Yuxingcao inhalation. Dry cough and the impact of sleep and diet, will be taking 0.5% of codeine syrup, each 0.1ml/kg, even daily with 1 ~ 3 times, the drug can inhibit the cough reflex, can inhibit breathing, it can not be abused or over dosage Great. Dextromethorphan dextromethorphan) each 0.3mg/kg, daily 3 to 4 times, there antitussive effect, but does not inhibit breathing.

eyes also need nutrition

Nutrition, eyes also need nutrition eyes are the body's vital organs, with a long eye, such as reading, watching television, the computer can cause eye fatigue, general fatigue, the spirit of extreme tension; malnutrition, the ultimate result is that vision decline.
Eyestrain common symptoms are headaches brain up, eyes dry, long-term eye fatigue, can cause vision loss and reducing efficiency.
As a result of modern television, computers, homework and work, excessive use of eyes, easy tears, fatigue, allergies, vision loss and other issues, usually eat more benefit from the eyes of food, already have of great help.
What food can add nutrition eyes do?
First, proteins, such as such as lean meat, poultry meat, animal offal, fish, shrimp, milk, eggs, beans and so on. Human tissue repair proteins necessary raw materials and, of course, the eyes are very important.
Followed by the vitamin a and c, vitamin a can prevent dry eye and night blindness, the elimination of eye fatigue, chronic lack of vitamin a time, vision will be a sharp decline, so adequate daily intake of vitamins should be a. Vitamin c is the composition of the eye lens, one of the ingredients, if a lack of vitamin c, it is easy to suffer from cataract disease. Therefore, the lack of vitamin a and c friends should eat a variety of fresh vegetables and fruits, especially carrots, amaranth, green peppers, cucumbers, cauliflower, Chinese cabbage, Fresh, raw fruit such as pears.
Finally, we frequently mentioned eyes can not be ignored, often massage about brows, eyebrows and the midpoint of the mid-point of the orbit, with the corner of the eye. On the visual help.

Causes of joint pain

In life, many people are troubled by joint pain. Joint pain caused by many reasons, according to age, sex, site of onset, symptoms characteristic of the general can be summed up in the soft tissue and cartilage and bone, and inflammatory and other reasons. Arthritis caused by any reason, such as timely medical care, and symptomatic treatment, cure or mitigation generally. Joint pain caused by the main reasons are:
1. joints around the ligament injury
Peg-leg knee ligament in the knee when the stability of the relatively poor, if at this moment by the external forces lead to a sudden or hallux varus, there are likely to cause medial or lateral collateral ligament injury. Trauma patients will have a clear history of knee pain, swelling, ecchymosis, activities restricted.
2. cartilage injury
Mainly knee meniscus injury, when the peg-leg at the knee, if a sudden excessive internal rotation or external rotation knee extensor (such as playing football, the play turned leg bending action), there is likely to cause meniscus tear. There will be obvious knee meniscus injury tear flu, was joint pain, activity limitation, walking claudication, joint activities are snapping.
3. joint synovitis
As a result of trauma or excessive strain injury and other factors synovial effusion after a large amount, so that intra-articular pressure increased, leading to joint pain, swelling, tenderness and friction Shibuya fat sounds. For example, take the initiative to extreme knee straight, especially that there is a certain resistance to do extensor movement, pain in the lower part of the patella will intensify. In extreme passive flexion, the pain will be significantly heavier.
4. autoimmune diseases
Immune system diseases such as lupus and psoriasis, will also appear swollen and painful joints violations, which rely on blood tests to help diagnosis.
5. Child Growth pain
Such patients are in the main growing period of the children, mostly boys. Pain is commonly found in the knee, hip and so on. This is growth and development of children emerged in the course of a normal physiological phenomenon. As a result of the growth phase of the children in bone growth relatively quickly, periosteum and local muscle growth and development of co-ordination, thus giving rise to discomfort, joint pain appears. It was also suggested that such pain is caused by infection of low toxicity.
6. traumatic arthralgia
Due to some accidents or incidents, so that shoulder, wrist, elbow, knee, and ankle joints and other parts of the fractures occurred in the absence of serious trauma cases, (such as soft tissue injury, fracture and dislocation, etc.) arising from joint pain.
7. Septic Arthritis
There are systemic infection in other parts of the history or the history of local trauma, pain, swelling of the joints can be, deep in the site also may not be apparent, but are elevated temperature, joint pain, not activities, such as elevated blood and so on.
8. osteoarthritis
Age at onset of osteoarthritis after the age of majority at 40. Joint pain morning heavier, more light during the day and night. Joint positions and spur Hyperosteogeny friction around the body, can cause pain in the joints.
9. osteoporosis
Older women more than the whole body joint pain, are particularly weak, not weight-bearing walking, if the exclusion of other diseases, may be suffering from osteoporosis.
10. rheumatic and rheumatoid arthritis
Occur in 20 to 45-year-old woman. Rheumatoid arthritis are often migratory pain (pain location uncertain), pain, swelling, stiffness and more occurred in the wrist position, and sensitive and swollen joints, pain simultaneous, symmetrical morbidity (such as double wrist, double knee ).

Symptoms of cervical spondylosis

As a result of the cervical, cervical disc itself and the surrounding muscle, ligament strain and other organizations, aging, trauma, stimulate, oppression and neck nerves, blood vessels, spinal cord, can cause neck and the Ministry of the upper limbs, head, or even a series of lower extremity The clinical manifestations. Medically known as cervical spondylosis.

Because, from the brain's nerves to be first out after the body arrived in cervical, head and upper limb blood supply would have to go through the cervical, therefore, caused by cervical spondylosis clinical symptoms are very complicated.

Comparison of cervical spondylosis light only appear neck, above, the hardware, pain, cervical flexion and extension, rotation activities can increase the symptoms. If the impact on the nerve leading to the upper limbs, the neck may also occur the Department of associated upper limb pain, or numbness, skin may also appear insensitive, upper limb muscle strength weakened. If the impact on access to the head of the nerves, blood vessels (vertebral artery), can occur dizziness, headache, nausea, vomiting, tinnitus, depending on material, such as unclear.

The main symptoms are: 1) activity limitation of head and neck, eyes closed, to the rotation around the head and neck, causing migraine headaches or dizziness. 2) the activities of pain from time to time. 3) stiff neck. 4) accompanied by hand pain paresthesia (skin allergies, ants go flu, fingers fever, chills, etc.). Fingers can not. 5) do not promote as a result of intracranial blood can cause ischemic behind the head and the performance of a series of symptoms such as migraine headaches, visual impairment, tinnitus and hearing loss and so on. 6) there is spinal stenosis may be caused in the bow suddenly body numbness, or has been feeling kind of power.
Answer 2:
If it is unreasonable because of the long-term posture caused by neck muscle stiffness caused by headache, dizziness, nausea, sleep quality and memory symptoms such as shoulder pain, and that the proposed massage, pull cans (not Cupping, which The most important step) treatment, soon will be the lifting of the problem. But if Cone because cervical lesions (hyperplasia or highlight) caused by spinal stenosis, caused by cerebral ischemia caused by the above-mentioned phenomena and the emergence of symptoms such as numb fingers, and that the proposed external Schiff spur consumer treatment, the drug mainly by cubeba ears, legal grass, shochu, borneol and other natural herbal composition, with Xiaozhongzhitong, softening rickets node, activating blood stasis, pass by the active function, mainly on: Gucining, periarthritis of shoulder, lumbar disc herniation, cervical pain, bone proliferation; of tennis elbow, bursitis, knee effusion, due to a sprain, trauma caused by muscle, ligament edema, atrophy, induration symptoms have a very good therapeutic effect. As for what kind of treatment, please according to their specific symptoms or to the hospital to determine the film.
Answer 3:
The main symptoms were acid wrinkle neck, shoulders acid, hand Ma, dizziness, headache, back acid Shen, upper arm or anterior lateral string pain, symptoms of many, but not necessarily the same time, you can visit our website to see a , the above detailed.

causes of headaches

Headache caused by many factors, which can be physical, chemical, biochemical or mechanical in nature. However, according to the site of a headache, nature, accompanied by the symptoms and the evolution of the situation, the general is able to ascertain the cause of headache.
Physical factors
Can cause pain organizations outside of intracranial inflammation, injury of a variety of reasons; a result of oppression, such as tumor causes vascular traction, stretching, displacement, expansion; meningeal irritation; muscle contraction; disposable head and face directly stimulate the sensory nerve, etc., can cause headaches.
Biochemical factors
Such as norepinephrine can vasoconstriction, histamine can intracranial vasodilator, bradykinin can produce aseptic inflammation and reaction. These substances can induce a headache.
Endocrine factors
Such as migraine headaches occur in the menstrual period, pregnancy mitigation, menopause is not fat, and tension headache is often heavier in the menopause. Intravenous prostaglandin can cause severe headache. Attacks and ease the headache often associated with endocrine more closely related. Neuropsychiatric factors when people are physically and mentally stimulating the adverse external environment often produce anxiety, anxiety and other emotions, resulting in a headache attack.

Others: such as the eyes, ears, nose and nasal sinus side, teeth, neck and other lesions may stimulate nerves, reflex or the impact of the proliferation of head and face, caused by or involving reflex headache. In addition, such as colds, high blood pressure and many other diseases will be the performance of a headache. Still has a lot of headache patients was no reason, but the head was swollen, heavy, tighten and so on. But most have fatigue, insomnia, concentration, memory and other symptoms, this is the function of neurasthenia headache patients.
In addition, severe anemia, uremic patients and smoking too many people will feel a headache, long-term living in the stuffy air or high-noise environments, are often a headache.

Health and food

To eating a certain amount of chromium. Chromium helps to promote cholesterol metabolism, enhance the body's endurance, In addition, it is certain physical conditions can also promote the formation of muscle and avoid excess fat. Middle-aged man one day at least 50 micrograms of chromium, while those larger volume of activities the day men will need 100-200 micrograms of chromium. So doses of chromium is very difficult to obtain from food, and therefore recommended that men taking chromium of pharmaceutical preparations (such as complex vitamins and minerals) or to drink beer.

To consumption of plant fiber rich food. The main function of plant fiber is able to speed up the gastrointestinal peristalsis, reduce cholesterol and some salt, reduce blood glucose and fatty acid, a step-down role, while elimination of some carcinogenic substances can to avoid suffering from rectal cancer . People eat plant fiber rich food are the feeling of satiety, but also not have to worry about accumulation of excess calories, it was also the effectiveness of weight loss. Recommendations for each meal when men consumed 18-20 grams of plant fiber. The main plant fiber rich food wheat bran, whole wheat bread, cabbage, potatoes, carrots, apples, lettuce, cauliflower, celery and so on.

To consumption of food containing magnesium. Magnesium helps to regulate the heart activity, lower blood pressure, prevent heart disease, improve the fertility of men. Recommends men should eat breakfast oatmeal with milk and a banana. Mg more food beans, baked potatoes, walnut, oatmeal, macaroni, leafy vegetables and seafood.

To consumption of food containing vitamin A. Vitamin A helps to improve people's immunity, prevent cancer, the protection of human vision. An adult male needs 1,000 micrograms per day of vitamin A, but excessive intake is hazardous to health. Containing vitamin A more food liver, dairy products, fish, tomatoes, carrots, apricots, cantaloupe.

To consumption of food containing vitamin B6. Vitamin B6 helps to improve people's immunity. Vitamin B6 can prevent skin cancer, bladder cancer, kidney stones. Men need to one day a total of 2 mg of vitamin B6, which is equivalent to two large content of bananas. Containing vitamin B6 more food chicken, liver, potatoes, sunflower seeds, avocado, banana and so on.

Vitamin C should be consumed with food. Vitamin C's primary role is to improve people's immunity, prevent cancer, heart disease, stroke, cataracts, protect teeth and gums, helps wound healing, anti-asthma, the treatment of male infertility. Also, insist on time to take vitamin C can delay aging process. Vitamin C content of the highest food cauliflower, green peppers, oranges, grape juice, tomato. U.S. experts believe that vitamin C per person per day should be the best dosage of 200-300 mg, the minimum not less than 60 mg.

A half glass of fresh orange juice per person per day is sufficient to satisfy the minimum amount of vitamin C. In addition, drink a half glass of orange juice a day can prevent a cold.

Smokers should be eating more vitamin C.

More consumption of food containing vitamin E. The main role of vitamin E is: lower cholesterol, physical removal of the rubbish and the prevention of cataracts. Walnut and peanut contains vitamin E, but it is difficult from these people have access to adequate food in the amount of vitamin E. Therefore recommends that men 10 mg daily doses of vitamin E Pharmacy.

Zinc consumption to food. Zinc can guarantee a man's sexual potency, treatment of male erectile dysfunction, and another, it also help to improve the body's resistance to disease. Recommendations men taking 15 mg of zinc, the dose is large amount of exercise for men, under normal circumstances; men only taking the dose for two-thirds of it. However, the daily volume must not exceed 15 micrograms, because excessive body would affect the role of other minerals. Lean meat high in zinc. In addition, turkey products, soybeans in the volume of zinc is also high.

To keep drinking water. Human cells can not be any lack of moisture, adult body is 60% -65% moisture, liver, brain, skin containing 70% water, 45% moisture content of bone, blood water content of 80%. If men want to keep fit and muscular, it is necessary to drink enough water, because the water in the muscle than fat in the water more than 3 times. Man of medium build and a day to be drinking 8 glasses of water, while the big men exercise demand for water is greater.

Because of pain in the eye

Most of the eyes because of pain in the eye itself caused problems, including infection by stimulating or injured. Although the eyes but sometimes the pain, in fact, diseases are emerging elsewhere, for example, or in the nose and paranasal sinuses. If you suddenly felt pain in the eyes (monocular or binocular have pain), then there may be caused by the following reasons:

1) c. Conjunctival lesions
Kok Conjunctival because microbial infection, physical and chemical factors that stimulate the inflammatory response that there are often caused by eye irritation, grinding pain, often accompanied by acute phase are jealous, such as an increase in tears. This situation only on the inflammation of the eyelid or complicated calculus treatment can.
2) asthenopia
Commonly found in close-up with longer working hours, such as students, editors and so on. Eye pain is usually pain, easy to tears, often turn for the better after the break.
3) supraorbital neuralgia
Because supraorbital nerve above the eyes and the surrounding skin, eye pain so often in and around the eyes sting, and some may have eye pain. Acupuncture and physical therapy to alleviate this pain to a certain extent.
4) glaucoma
Acute congestive glaucoma attack, the intraocular pressure may be increased to 70 mm Hg or more, there will be severe eye pain, headache, with jealousy, vision, nausea, vomiting.
Many patients are often the first diagnosis of internal medicine, neurology, led to delays in the disease. Under the circumstances required to carry out emergency treatment of ophthalmic through drugs reduce intraocular pressure, improve the water cycle eye condition, rescue visual function. When necessary, the need for emergency surgery.
Love Tip: There is also a situation of chronic elevated intraocular pressure is often mild eyes bulging, acetify. With time, the eye gradually adapt to the intraocular pressure, eyes bulging and so does not apply to go away.
The disease often leads to delays, therefore, be significantly decreased when the visual treatment, the disease often has reached a late stage. This requires vigilance, especially those with risk factors for glaucoma crowd, such as the family have glaucoma, high myopia, diabetes, such as central retinal vein occlusion.

function of teeth

Different teeth have different functions, but they have a common feature: chewing, pronunciation, and beautiful.

Chew: humanity is a wide range of food, fiber-rich foods, and food starch, which have food and the size of soft and hard, it requires a high degree of differentiation of the teeth, to adapt to the diversity of human food . If incisor can be steamed, Luo Bing, fruits, whole foods, such as cutting down at times for chewing in the mouth. The canine has a sharp tip of the tooth, can Pig, indica toughness of fiber and other food to tear open. Premolars and molars, to Yaosui various types of food, ground. A variety of different forms of teeth, are coordinated together, both the division of labor, and work together to complete chewing function.

Pronunciation: to issue a wide range of human voices to express ideas or feelings of the exchange, in the teeth to help pronunciation when play a vital role, it can help dental issue. If the missing front teeth, not words sound together, leakage, dental made inaccurate, the natural language is not clear.

Appearance: neatly arranged on the lower jaw teeth, cheek and lips will support the face, the face appears to be full. If the upper and lower teeth bite abnormalities, such as anti-bite, prominent chin forward, the package covered under the teeth on teeth, so that the shape change, aesthetic impact. If the whole toothless mouth, lip and cheek and soft tissue lack of support, inward collapse, folds appear, appears to be old.

Formation of urine

Kidney is the organ of the body produce urine, most of the body of water, salts and organic compounds are eliminated from the body through the urine, the urine formation in the human body for the maintenance of the environment is vital.
The formation of urine: the formation of urine through the main glomerular filtration, tubular and collecting duct reabsorption, and renal collecting duct secretion, excretion process of the three in a row.
The glomerular filtration: the cycle of blood flow glomerular capillaries, plasma water and small solute molecules, including a small number of smaller molecular weight plasma protein through the kidney filtration membrane filter to the small capsule of the formation of intracavitary Ultrafiltrate (original urine), and this is the role of the so-called glomerular filtration.
Glomerular filtration role in the decision of the three main factors:
(1) filtration membrane filtration is the permeability of the structure of the foundation. Is the glomerular filtration membrane of the blood capillaries and small kidney capsule more than every other mode between the filtrate, mainly by the endothelial cells, non-cell-based film and the renal capsule of visceral epithelial cells Cheng, both to prevent membrane filtration macromolecular material filter out the mechanical barrier, and prevent the filter material with a negative charge of static electricity barrier. As a result, the kidney filtration through the membrane, not only filter the water liquid form of the original urine can be retained in the body of useful material at the same time, the body's waste discharges.
(2) effective filtration pressure is the driving force for filtration. Effective filtration pressure by the strength of 3: 1, 0000 glomerular capillary pressure, which is to promote the power of the filter. 2, 0000 plasma colloid osmotic pressure, it is to stop the plasma filter out the power of water. 3, 0000 intracapsular pressure, it is against the power of the filter. Effective pressure = glomerular filtration pressure - (plasma colloid osmotic pressure Capsule +). Where can affect the glomerular capillary pressure, or plasma colloid osmotic pressure of the capsule, can make changes in glomerular filtration pressure, thus affecting the glomerular filtration rate.
(3) renal plasma flow filtration is the premise and basis of the material. Renal plasma flow and glomerular filtration rate in direct proportion to, when the renal plasma flow increased, the human form of urine also increased.
Tubular and collecting duct of the re-absorption: When the original flow through tubular, the occurrence of re-absorption, the original of all the glucose in urine, most of the water and inorganic salts were part of the tubular re-absorption and into the enveloping the tubular Outside the capillaries, to send back to the blood. The remaining part of the water, and inorganic waste such as urea on the formation of urine outflow from the tubular.
And the impact of renal collecting duct reabsorption of factors:
(1) tubule fluid in the concentration of solutes. Tubule solute in liquid form by the osmotic pressure, is tubular and collecting duct water absorption of force against. If the small tube of liquid solute in high concentrations, the osmotic pressure to form a large, tubular reabsorption of water against the force, the results can increase urine, which is called osmotic diuretic.
(2) glomerular filtration rate. Proximal tubule reabsorption per minute ml of liquid filtration, said the rate of tubular reabsorption, and glomerular filtration rate to maintain a balance between, known as the Tube strike a balance. Its physiological significance is the end result of urine will not increase or decrease in glomerular filtration rate and drastic changes.
(3) renal tubular epithelial cells. Tubular epithelial cells have a strong re-absorption, and selective, when some of the parameters of the function of cells, renal tubular injury may be caused by the re-absorption of obstacles, leading to increase in the volume of urine or appear in some unusual ingredients.
Tubular and collecting duct secretion, excretion: renal collecting duct and the secretion that the tubular and collecting duct epithelial cells, through its own metabolism resulting from the material released into the fluid in the tubules. Excretory functions, it means tubular epithelial cells in the blood of the Central Plains have some of the material into the small tube of liquid. In the process of renal excretion of H ion secretion, NH3, K ion, and through the exchange of sodium and sodium hydrogen exchange, retains sodium, in addition to the body produced by normal creatinine and uric acid, such as Ma-on, not only from the glomerular Filtration, but also by renal tubular excretion into the body of certain substances, such as penicillin, phenol red, and so on through the excretion of the proximal tubules, lumen into small, and then eliminated from the body of.
When the formation of urine, renal kidney in millions of units of the formation of urine in the pool pelvis, ureter, after the transport, storage for the time being, in the bladder.
The formation of urine is a continuous, discharge of urine is the interval. When the bladder urine of bladder, a certain amount of storage, the pressure on the bladder wall, intended to produce urine. Urination, the bladder muscle contraction, the urethral sphincter to relax, urine from the bladder outflow through the urethra eliminated from the body.
