1, the normal average heart rate: 75 times per minute Healthy adults in a quiet state, the average heart rate of 75 times per minute (normal range of 60 to 100 times per minute) adult quiet heart rate more than 100 times / minute, for tachycardia; less than 60 times / minute, for bradycardia. Popular medicine reminder: 75 times is only an average, heart rate can be due to age, gender and other factors and changes, such as body temperature rises every 1, the heart rate can be accelerated by 12 to 20 times / min; female heart rate is slightly faster than the male; athletes heart rate is slower, it can be lower than 60 beats per minute and so on. 2, the normal body temperature: 36.3 ~ 37.2 (oral measurement method) clinically, usually use the oral temperature rectal temperature and armpit temperature to On behalf of the body temperature oral method (sublingual 5 minutes) normal value of 36.3 ~ 37.2; axillary method (axillary clamping 5 minutes) for 36 ~ 37, anal method (table head coated with lubricant, inserted into the anus for 5 minutes) for 36.5 ~ 37.7 in the day and night, the human body temperature is cyclical fluctuations, generally early in the morning from 2 to 6 times the lowest, 13 to 18 times the highest in the afternoon, but fluctuations in the range of generally no more than 1 mass! Medical Alert: Is a body temperature of 37.1 measured by the oral method considered feverish? The correct answer is whether because as long as the body temperature does not exceed 37.3, even if normal 3, hemoglobin (HbB): adult men (120 ~ 160 g / liter), adult women (110 ~ 150 g / liter) Clinical hemoglobin value as a basis for determining anemia normal adult hemoglobin value of 90 ~ 110 g / liter of mild anemia; 60 ~ 90 g / liter of moderate anemia; 30 ~ 60 g / liter of severe anemia. g / l is a severe anemia; <30 g / l is a very severe anemia pregnant women due to blood dilution during pregnancy, hemoglobin less than 100 g / l is anemic Popular medicine reminder: different causes or types of anemia, the treatment method is very different once you find anemia, you should go to the hospital, in a clear cause of anemia (primary or secondary) and type (iron deficiency or megaloblastic), and then targeted treatment Do not buy blood supplements on your own, so as not to delay the condition 4, white blood cell count (WBC): 4 to 10 × 109 / liter white blood cell count is greater than 10 × 109 / liter called leukocytosis, less than 4 × 109 / liter is called leukopenia Generally speaking, acute bacterial infections or inflammation, the white blood cells can be elevated; viral infections, the white blood cells will be lowered Popular medicine reminder: the cold fever can be caused by a viral infection, can also be caused by a viral infection, can also be caused by a viral infection, can also be caused by a viral infection. Viral infection can be caused by viral infection, can also be caused by bacterial infection, in order to clarify the cause of the disease, to guide the clinical use of medication (antibacterial or antiviral), the doctor will usually let you go to check a blood routine at this time, don't think that the doctor in the indiscriminate prescribing of laboratory tests Oh, it should be said that, this blood still need to be examined 5, Platelet count (PLT): 100 ~ 300 × 109 / liter platelets have to maintain the integrity of the wall of the vessel when the platelet count is reduced to 50 × 109 / liter. When the platelet count decreases to less than 50×109/liter, especially when it is as low as 30×109/liter, it may lead to bleeding, and petechiae and ecchymosis may appear on the skin Popular medicine reminds: many people do not have low platelet counts, and there are often bruises on the skin, which is mainly due to the fact that in addition to the platelet factor, the vascular wall factor coagulation factor, and a number of physiological factors can lead to the occurrence of bruises when you find that you often have a bruise. When you find that you often have a blue block, do not be overly nervous, you can go to the hematology clinic to clarify the cause 6, urine volume: 1000 ~ 2000 ml / 24 hours 24-hour urine volume > 2500 ml for polyuria physiological polyuria is seen after drinking too much water or the application of diuretics pathological polyuria is seen in diabetes uremic renal tubular disease, etc. 24 hours of urine volume < 400 ml for urine, most often due to dehydration, drinking too little water Renal insufficiency, etc. 24-hour urine volume <100 ml is anuria, mostly seen in renal failure, shock and other serious diseases Popular medicine reminder: if you feel that you have recently increased the amount of urine, especially easy to be thirsty, you should go to the hospital for examination, to rule out whether you have diabetes or renal tubular disease if you find that you recently drink quite a lot of water, but the amount of urine is on the low side, and a little bit of swelling, you should be examined in a timely manner, to rule out renal disorders. 7, Nocturia: 500 ml Nocturia refers to the total urine volume from 8 p.m. to 8 a.m. of the next day, generally 500 ml, 2-3 times urination if the amount of nocturia exceeds the amount of urine during the day and the number of times of urination increased significantly, known as nocturia increased physiological nocturia increased with too much water before going to bed; pathologic nocturia increased for the kidneys concentration function is often impaired performance, is the early sign of renal decompensation Popular medicine reminder: nocturia is an abnormal signal. An abnormal signal, we should pay enough attention in addition to renal hypoplasia, increased nocturia may also be male prostate hyperplasia elderly women uterine prolapse urinary tract infection diabetes mental stress and other reasons 8, urine red blood cell count (RBC) normal value: 0 ~ 3 / high power field of view urea red blood cell > 3 / high power field of view, said the microscopic hematuria urea red blood cell> 10 / high power field of view, said the visual hematuria mass Medicine reminds: urine erythrocyte count if more than 3, often suggests kidney disease or urinary tract infection, should immediately seek medical attention Women should avoid checking the urine routine during menstruation, so as to avoid the menstrual blood mixed with the urine to affect the results of the test 9, urine white blood cell count (WBC) normal value: <5/high-power field of view urine leukocyte count of >5/high-power field of view, known as microscopic pus urine Popular medicine reminds: urine if there are a large number of white blood cells, most of the urinary tract infections, the urine is not a good place for the urine. Most of the urinary tract infections, such as pyelonephritis, renal tuberculosis, cystitis or urethral infections If there are white blood cells in the urine, but less than 5 / high power field of view, even if the normal 10, sperm survival time: 72 hours Egg survival time: 24 hours Popular medicine reminds: many couples like to use the safe period contraceptive method of contraception, but unfortunately, many people encountered a safe period of insecure trouble What is the reason for this? In addition to getting the ovulation period wrong, there is a factor that should not be ignored: as the sperm can survive in the female body for as long as 3 days, so even if the day is not ovulation, as long as in the conception period (4 days before ovulation to 2 days after ovulation), the woman is still very likely to be conceived 11, the two major blood group system: ABO and Rh ABO blood group system will be divided into 4 types of blood: type A type B AB and type O Rh blood group system will be divided into two types of blood: type A type B and type O, the blood group system will be divided into two types of blood: type A type B and type O. Blood type is divided into two types: Rh-positive type and Rh-negative type in Caucasians, 85% for Rh-positive blood type, 15% for Rh-negative blood type in China, 99% of the Han Chinese belong to the Rh-positive blood type, Rh-negative belong to the rare blood type Popular medicine reminder: If the father is A-type blood, the mother is B-type blood, the child should be what blood type? The correct answer is type A, type B, type AB or type O. Don’t think it’s strange to give birth to a type O baby because both husband and wife are not type O! If there is a person for AB type, the baby can not be O type both sides if both are O type, the baby can only be O type 12, body mass index (BMI) = weight (kg) / height (m) square: 18.5 ~ 23.9 is normal body mass index <18.5 for underweight, body mass index of 24.0 ~ 27.9 for overweight, body mass index of 28.0 for obesity Popular medicine reminder: if your body mass index exceeds 24, it means that you are already in the process of the Index more than 24, that you have been obese, need to lose weight Remember: obesity is the source of all diseases, if you let it, diabetes, hypertension and coronary heart disease will find you 13, the best rate of weight loss: monthly weight loss of 1 to 2 kg Popular medicine reminds: overweight people should be under the guidance of a doctor to gradually reduce the weight of the weight loss is too fast and too fierce will lead to weight regression anorexia anemia malnutrition menstrual disorders hair loss memory loss and other adverse reactions 14, osteoporosis and other adverse effects Osteoporosis and other adverse reactions 14, waist circumference: male 90 cm, female 80 cm for abdominal obesity Waist circumference is to determine the accumulation of abdominal fat, that is, abdominal obesity (also known as apple-type obesity) indicators abdominal obesity is currently considered to be the coronary heart disease metabolic syndrome an important risk factor Popular medicine reminds: If your body mass index has not yet reached the degree of obesity, but the waist circumference has exceeded the standard, indicating that you belong to abdominal obesity abdominal obesity Obese people are more dangerous than the whole body is fat, more likely to be favored by coronary heart disease diabetes, beware! 15, obesity signals: a month weight gain of 1.5 kg Popular medicine reminds: in the weight just began to grow up when the timely detection, and take measures to lose weight, often can receive significant results in the following cases, often suggesting that there is a tendency to weight gain: a little exercise is out of breath, fatigue and weakness, immobility on the sweating, lower back hip and knee pain 16, blood pressure normal values: systolic blood pressure < 140 mm Hg, diastolic blood pressure <90 mm Hg in the quiet without the use of anti-high hanging renewed that the salts squid captured the order of ken terrier Liao Liao supine fear (11) quality account of dancing?40 mm Hg and/or diastolic blood pressure of 90 mm Hg, can be diagnosed as hypertension systolic blood pressure of 140 mm Hg, but diastolic blood pressure <90 mm Hg, known as simple systolic hypertension Popular medicine reminder: high blood pressure is the cardiovascular and cerebral vascular disease is an important risk factor for high blood pressure Patients should apply antihypertensive drugs under the guidance of a doctor to control blood pressure in the normal range of diabetic nephropathy, it is best to control blood pressure below 130/80 mmHg 17, diabetes mellitus diagnostic criteria: fasting blood glucose > 7.0 mmol/L, and/or 2 hours after meal blood glucose > 11.1 mmol/L Popular medicine reminds: If your blood glucose value meets the above criteria, it means that you are a diabetic patient, should be under the guidance of a doctor to reduce glucose. Should be under the guidance of the doctor to lower sugar treatment, do not refuse treatment because diabetes is not much feeling to know that, if blood sugar is not properly controlled, all organs of the body will be involved 18, diabetes exclusion criteria: fasting blood glucose <6.1 mM / l, and 2 hours after meals blood glucose <7.8 mM / l Popular medicine reminder: if your blood glucose value meets the above criteria, it means that your blood glucose is completely normal, can rule out diabetes 19, pre-diabetes diagnosis: pre-diabetes diagnosis: if you meet the above criteria, it means that you are diabetic. Can rule out diabetes 19, pre-diabetes diagnostic criteria: 6.1 mM / l < fasting blood sugar < 7.0 mM / l, and/or 7.8 mM / l < 2 hours after meals < 11.1 mM / l Popular medicine reminder: if your blood glucose value is higher than normal, but has not reached the diagnostic criteria for diabetes, it means that you are in the pre-diabetic period at this time, if you do not raise the vigilance, do not actively intervene. 20, diabetes warning signals: fasting blood glucose > 5.6 mmol/L When fasting blood glucose more than the standard, the incidence of diabetes in the population increased significantly, ischemic heart disease and other cardiovascular events and the incidence of diabetic retinopathy increased significantly Popular medicine reminder: fasting blood glucose > 5.6 mmol/L should be checked as soon as possible in the hospital for an OGTT (OGTT) to determine whether the postprandial blood glucose increase. Determine whether there is postprandial blood glucose elevation because in the early stage of diabetes or impaired glucose tolerance, fasting blood glucose can be completely normal 21, normal value of glycated hemoglobin 6.5% Glycated hemoglobin is the product of hemoglobin and glucose binding in red blood cells, which can reflect the average blood glucose level of the three months prior to the collection of blood, and it is the most effective and most reliable indicator of the control of blood glucose in diabetic patients. 7.0% as one of the standards of treatment, the elderly can slightly relax the standard (7.0% to 7.5%), the young people should control the glycated hemoglobin at 6.5% or lower Popular medicine reminder: every 1% drop in glycated hemoglobin, diabetes-related complications can be reduced by 20%, therefore, even if diabetic patients can not meet the above standards, should be reduced to close to normal as far as possible. Normal 22, the period of the highest bone density: 30 ~ 40 years old The period of the highest bone density (peak bone) in the life of each person generally appears in the age of 30 ~ 40 years old, subject to the nutritional development after birth and genetic factors such as the influence of the peak bone value is high and low men generally from the age of 40, women generally from the age of 35 years old, the peak bone value began to decline in women in the postmenopausal period within 5 years after menopause, men after the age of 70, the fastest loss of bone mass Popular medicine reminds: peak bone high people, its bone calcium content is high, the degree of osteoporosis occurs after old age is milder time later Therefore, before the age of 40 people should seize the opportunity to ensure that every day enough nutrition and calcium intake, and actively participate in physical exercise, and strive to improve their own peak bone 23, per person per day, 25 grams of oil is appropriate Popular medicine reminds: the best way to cook with vegetable oil, because vegetable oil contains on the heart healthy saturated fatty acids. Heart-healthy unsaturated fatty acids more calories due to oil, so the amount should not be too much, otherwise excess calories, will also be converted to body fat, let you get fat 24, the amount of salt per day should not exceed 6 grams of popular medicine to remind: Salt is an important risk factor triggered by high blood pressure, people with heavy taste should pay special attention to the amount of salt per day should also include soy sauce pickles salted eggs in the amount of salt 25, every day eating vegetables 400 to 500 grams of popular medicine reminds: more than half of the daily consumption of vegetables should be colored vegetables, such as green leafy vegetables red and yellow vegetables vegetables rich in vitamins, minerals and fiber, calories and is very low, is a real health food 26, healthy adult daily intake of calcium 600 to 800 mg Chinese Nutrition Society recommended calcium supply: adults 600 to 800 mg / day, pregnant women 1200 mg / day, breastfeeding mothers 2000 mg / day The Chinese Academy of Nutrition recommended calcium supply: adults 600 to 800 mg / day, pregnant women 1200 mg / day, breastfeeding mothers 2000 mg / day Popular medicine reminds: milk and dairy products rich in calcium, high absorption rate of aquatic products, shrimp and seaweed soybean products containing more calcium in order to promote the absorption of calcium, should be appropriate supplementation of vitamin D and more sun 27, drinking water more than 1500 milliliters per day Popular medicine reminds: drinking water, including daily intake of tea, water, soup, fruits and other foods, the total water drinking water is very delicate, the mouth does not thirst to drink water. Do not drink a lot of water at one time, but drink plain water or tea, and do not use sugary drinks instead of water, etc. 28. The best time to start rehabilitation for stroke: 3 days after cerebral infarction, and 5-7 days after cerebral hemorrhage. Popular medicine reminds that: so far, there is not a single drug at home and abroad that has a decisive effect on hemiplegia, and the only effective way to improve the dysfunctions of stroke patients is rehabilitation training for hemiplegic patients. For hemiplegic stroke patients, rehabilitation training is far more effective than medication, and the earlier, the more scientific, and the more complete the rehabilitation training, the greater the chances of recovery. 29. Normal value of alanine aminotransferase (GPT or ALT) is <40 units/liter. Popular medicine reminds that: the elevation of GPT is mostly suggestive of liver damage, such as acute and chronic viral hepatitis, alcoholic hepatitis, drug-induced hepatitis, cirrhosis, and so on, which should be consulted in time in hospitals. 30, Alpha-fetoprotein (AFP) <25 micrograms/liter (also refer to the normal reference value on the laboratory test) Alpha-fetoprotein is a glycoprotein synthesized by the liver in the early fetal period After birth, the synthesis of AFP is quickly inhibited when the liver cells undergo malignant changes, the AFP content in the blood increases significantly Popular medicine reminder: the AFP is elevated, especially when it is slightly higher than the normal value, which does not necessarily mean that it suffers from malignant tumors, and it should be observed dynamically. Stroke thrombolytic time window: 3 hours after the onset of brain infarction, if the intravenous thrombolytic therapy can be given within 3 hours after the onset of brain infarction, it can maximize the blockage of blood vessels, save dying brain cells, and effectively reduce the occurrence of complications and sequelae Once you miss this time window, thrombolytic therapy is almost ineffective. One side of the hands and feet are not flexible, numbness, aphasia, blurred vision, etc.), do not be negligent, should go to the hospital immediately, in order to buy time for treatment 32, 18 ~ 45 years old, myopia <1200 degrees: excimer laser myopia surgery Popular medicine reminds: the age of 18 years of age; myopia is unstable, and there is a tendency to deepen in recent years; myopia > 1200 degrees; the eye has activity The eye has active lesions (such as inflammation glaucoma dry eye, etc.); cornea central thickness <450 microns; there are other serious eye diseases (such as cone cornea, etc.); autoimmune diseases keloidal and severe diabetes, etc., are not able to do excimer laser myopia surgery 33, 40 years of age or older, check the ultrasound annually Ultrasound has the advantages of non-invasive non-radiation convenient and accurate ultrasound can not only find stones, cysts, fatty liver and other common diseases, but also early detection of some of the most common diseases. Common diseases, but also early detection of certain tumors Popular medicine reminds: by the physical properties of ultrasound, ultrasound is more suitable for solid organs, such as the liver, spleen and kidneys, etc., generally not suitable for gas-containing organs (such as the stomach and intestines) and the skeletal system 34, 40 years of age or older women, check once a year molybdenum target photography In recent years, the incidence of breast cancer has been a trend of increasing year after year molybdenum mammography of breast cancer, especially in early stage has a high diagnostic value, clinical diagnosis, and clinical diagnostic value. Mammography has high diagnostic value and is clinically used as a preferred diagnostic imaging method in addition to physical examination. If there are high-risk factors such as family history of breast cancer, women should receive annual mammography examination from the age of 35 years old onwards and increase the number of examinations according to the doctor's opinion after the age of 40 years old. 35, women over 45 years old, men over 55 years old: 1 time a year to measure bone density The prevalence of osteoporosis in people over 60 years old is 30% to 35% for women and 10% to 20% for men The hazards of osteoporosis on human health are manifold, such as back pain, short stature, humpback and bone fracture. Bone density testing equipment is dual-energy X-ray absorptiometry, commonly known as bone densitometer bone densitometer can determine the proximal lumbar femur or bone mass of the whole body bones, can accurately reflect the loss of bone mass you should be measured every year to keep the data properly, and compared with their first measurement of the bone density value (the initial data), in order to grasp the situation of the loss of bone mass every year once the bone density value of the osteoporosis standard, you need a doctor's guidance to formalize the osteoporosis. Once the bone density value reaches the standard of osteoporosis, it is necessary to carry out regular medication under the guidance of the doctor to maximize bone density and prevent fractures. 36. Calculation of the expected date of delivery: the month of the date of the last menstrual period, plus 9 or minus 3, is the number of months of the expected date of delivery; the number of days, plus 7, is the number of days of the expected date of delivery. For example: Xiao Lin's last menstrual period was May 3, 2006, and the expected date of delivery was approximately: February 10, 2007. Every woman's menstrual cycle varies in length, so the calculated due date and delivery date may have an error of 1 to 2 weeks 37, prenatal checkups: 9 times the best In addition to the need for one checkup in early pregnancy to determine the pregnancy, from mid-pregnancy to the full-term pregnancy, about 9 prenatal checkups are needed generally 20 weeks of pregnancy to 36 weeks, every 4 weeks of checkups; 36 weeks of pregnancy, weekly checkups, 9 checkups were 20 weeks, 24 weeks, 28 weeks, 32 weeks, 36 weeks, 20 weeks and 28 weeks. 24 weeks 28 weeks 32 weeks 36 weeks 37 weeks 38 weeks 39 weeks 40 weeks Popular medicine reminds: formal prenatal checkups are generally nine times, but for pregnant women with certain high-risk factors, may need to increase the number of checkups and projects at any time 38, the weight gain during pregnancy should not be more than 15 kilograms of expert advice: pre-pregnancy weight of women with normal body weight, the weight of the pregnancy can be increased by 11.25 to 15 kilograms of pre-pregnancy weight of women who have low body weight, the weight during pregnancy can be increased by 12 kilograms of weight. Women with low pre-pregnancy weight can increase their weight during pregnancy by 12.6 to 18 kilograms Women with heavy pre-pregnancy weight should have some control over their weight gain during pregnancy, which should be 6.75 to 11.25 kilograms Popular medicine reminds that: the amount of weight gained during pregnancy indirectly affects the growth rate of the fetus and the weight of the fetus Weight gain during pregnancy is too much and too fast, which not only increases the incidence of macrosomia, but also makes it more difficult to lose weight after delivery. On the contrary, if the weight gain is too little, it will affect the normal growth and development of the fetus 39, pregnant women: menopause 5 to 10 weeks of the most dangerous medication In the first 2 weeks after conception, the fertilized egg if affected by the drug there may be two endings: one is a spontaneous abortion; the other is that the fertilized egg to repair the damage to itself and continue to develop into a normal fetus Therefore, if a pregnant woman is not careful to take the drug at this stage, you can take a wait-and-see attitude of nature! However, 3 to 8 weeks after conception (i.e., 5 to 10 weeks after menopause) is a critical stage of embryonic organ differentiation and development, at this time, if exposed to harmful drugs, embryonic organs may be teratogenic Popular medicine reminder: as most of the drugs on the fetus are concentrated in the early stages of pregnancy, and at this time there are a considerable number of pregnant women do not yet know that they are pregnant in order to ensure the safety of the prospective mothers should be in the stage of preparation for the pregnancy began to consider the use of drugs Safety issues 40, full-term birth: 37 weeks of pregnancy to less than 42 weeks of delivery Premature birth: 28 weeks of pregnancy to less than 37 weeks of delivery overdue birth: 42 weeks of pregnancy or more than 42 weeks of delivery Popular medicine reminder: in the 38 weeks of pregnancy when the birth, although it is not yet to the expected date of delivery (40 weeks of pregnancy), but also counted as a full-term birth Oh 41, normal newborn weight: 2500 ~ 4000 grams birth weight < 2500 grams, known as low birth weight; birth weight > 4000 grams, known as the huge children Popular medicine reminds: huge children will not only increase the rate of difficult labor cesarean section rate, and too much weight gain during pregnancy, will make the pregnant woman feel uncomfortable pregnancy complication rate increases, and postpartum to lose these excess weight is also very difficult low birth weight children mainly include preterm babies and small samples of these children due to the congenital insufficiencies, complications, high perinatal mortality rate for the DuPont University of Technology and Science. These children have many complications due to congenital deficiencies, high perinatal mortality rate in order to put an end to this large and small phenomenon, regular obstetric examination, timely detection of problems, timely intervention, is very important 42, full-term newborn length: about 50 centimeters The height of the child in the first year of life grows the fastest, the annual growth of about 25 centimeters after 1 year of age the growth rate slows down, the annual growth of about 10 centimeters after 2 years of age, the growth of even slower, on average, the annual growth of 5 centimeters from 2 to 12 years of age, the child’s height calculation formula Height = age × 6 + 77 (cm) Popular medicine reminds: If the height of a 2-year-old child in a year almost did not increase, parents should be vigilant, as soon as possible to take the child to the hospital for examination, to rule out the secretion of growth hormone insufficient hypothyroidism and other problems 43, 6 months, the first milk teeth eruption Pediatric teeth are generally 6 to 7 months, or may be earlier than 4 months, the latest not more than 10 months milk teeth a total of 20, the latest at 2 years and a half, permanent teeth began to grow at the age of 6 years Popular medicine reminder: 11 months old children did not come out of the teeth, or more than two and a half years old children’s teeth are abnormal, should be identified as the cause of cretinism rickets nutritional deficiencies in children with late teething 44, pericardium 4 years of age, the best treatment Correction of pericardium is the principle of elimination of the cause of the early treatment to prevent deformities foreign orthodontists advocate the treatment of pericardium from 4 years of age until 18 years of age, the best treatment for pericardium. The best treatment is at the age of 4. Foreign orthodontists advocate the treatment of pericardium from the age of 4 and continue until the age of 18. Popular medicine reminds that: pericardium during the period of milk teeth is very harmful, not only hindering the normal growth and development of the children’s oral cavity, face and jawbone, but also adversely affecting the children’s mastication and pronunciation of the social and even psychological, and it should be treated as early as possible. 45, precocious puberty: the girl before the age of 8 years old, breasts begin to develop or menstruation occurs before the age of 10 years old, and the boy before the age of 9 years old, penis testicles enlargement except for Organic lesions (intracranial tumors) caused by precocious puberty need to target the original disease for treatment, precocious puberty on children’s greatest harm is not tall, because sex hormones early secretion will make the epiphysis closed early In addition, from a sociological point of view, precocious puberty will also bring negative psychological impact on the child Popular medicine reminds: overnutrition blindly tonic is the cause of children’s precocious puberty is more and more important reason parents should not Because of the fear of children’s nutrition is not enough, and constantly give children messy nutrition and eat supplements, so as not to love into harm 46, amblyopia: corrected visual acuity of 0.8 amblyopia is a kind of ophthalmological examination without abnormal lesions, but corrected visual acuity of less than 0.8 eye disease amblyopia patients do not have perfect stereoscopic visual function, can not be engaged in fine work amblyopia efficacy is closely related to the age of amblyopia is generally believed to be the best time for the treatment of the age of 4-6 years old, 12 years old, the efficacy is gradually reduced. It is generally believed that 4 to 6 years old is the best period for treatment, after 12 years old, the efficacy of the treatment gradually decreases, and there is basically no cure possibility in adulthood. Popular medicine reminds that: since the appearance of both eyes of amblyopic children is no different from that of normal children, it is difficult to find the abnormality just by observing, so it is suggested that children over 4 years old should go to the hospital to check the visual acuity on a regular basis so that amblyopia is found in the early stage. 47, pediatric cryptorchid testis surgery: the latest should not be delayed than the age of 4 years old. Cryptorchidism is a common congenital abnormality of testis, one or both testes of patients fail to descend into the scrotum normally, if not diagnosed and treated early, it will cause infertility or testicular tumors and other serious problems at present, it is advocated that cryptorchidism should be treated at an early stage, Coronary artery stenosis >70%, need to do intervention It is generally believed that coronary artery stenosis <70%, can be treated with medication; coronary artery stenosis >70%, need to do intervention If there are obvious symptoms, stenosis >50% should also be done intervention In addition, some special circumstances, such as coronary artery stenosis is not enough to intervene in the treatment of the standard, but imaging shows that the lesion is unstable in shape, prone to thrombosis, should also be Early intervention Popular medicine reminds: more than two coronary artery stenosis > 50%, or received coronary angioplasty and stent installation in the coronary artery patients again angina pectoris, should receive bypass surgery 49, hearing loss of 60 decibels, wearing a hearing aid is the best effect In general, unilateral deafness or mild deafness do not need to wear hearing aids; hearing loss of 35 to 85 decibels, it is recommended to use a hearing aid; hearing loss of 35 to 85 decibels, it is recommended to use a hearing aid; hearing aid; hearing loss of 60 dB of hearing loss, it is recommended to use a hearing aid; hearing loss of 60 dB of hearing loss; hearing loss of 50 to 85 dB of hearing loss. Hearing aids; hearing loss > 85 decibels, hearing aids can increase the volume, but due to the patient’s language recognition rate is very low, no practical value Popular medicine reminds: hearing loss of the elderly should go to the hospital to do a hearing examination, the doctor to decide whether you need to choose to match the hearing aids 50, 30 times the nuclide examination = X-ray chest X-ray Popular medicine reminds: examination of the heart, the thyroid, lungs, gastrointestinal tract, and other diseases are often used to check the radionuclide examination is a peaceful use of the nuclear examination. Radionuclide examination, is a peaceful use of atomic energy technology, with a certain degree of radioactivity, many patients are therefore quite concerned about the examination in fact, the examinee in the examination of the radiation dose is only 1/30 of the X-ray chest X-ray, will not have any impact on health.
