Aging has always been one of the most concerned topics. Many people want to know why the same age, but everyone’s aging degree and health condition are very different. What determines people’s aging speed and how to fight aging more effectively? Recently, a study published by Stanford University in the International Journal of Nature Medicine, for the first time, classifies human aging into four types according to the changes of genes and molecules in the body. Let’s see which one you are? 1, 4 types of aging have corresponding disease risks! There have been a lot of studies on aging in the past, usually focusing on a certain factor, but this time they are more comprehensive than before. Stanford researchers have studied 106 individuals for two years, including proteomics, metabonomics, transcriptomics, cytokines, genes, routine clinical tests, nasal and intestinal flora, etc., and evaluated a number of indicators. The results show that people’s aging speed is different, and the factors causing aging are also different. A person may have multiple types of aging at the same time, and all of them have corresponding disease risk! 1, immune type: inflammation, infectious diseases and cancer, refers to the aging of the immune system faster in the process of aging. Immune aging will directly lead to the increased risk of various types of inflammation and infectious diseases. Moreover, recurrent or persistent chronic inflammation will increase the risk of cell canceration. According to statistics, 85% of cancer occurs after the age of 45. Some studies have found that the immune capacity of 40 years old is half of that of 20 years old, and only 20% is left by 70 years old. After 60 years of age, the number of T lymphocytes, an important immune cell, will drop to 70% of that of young people, and the self-healing ability of bone marrow stem cells will also decrease. Even as the central organ of human immune system, the function of thymus will be further reduced, which may form the second peak of disease in life. [feature tips] after 50 years old, he has long-term mild to moderate chronic inflammation, such as esophagitis, gastroenteritis, pancreatitis, laryngitis, pneumonia, etc.; in routine blood tests, the number of white blood cells and platelets is abnormal for a long time; after 60 years old, he is weak and sickly, often catching cold and fever. 2. Metabolic type: obesity and “three highs” refer to the aging of metabolic related system functions. Here we need to distinguish one point, that is, basic metabolism and metabolism are two concepts: metabolism has real-time volatility, such as drinking more water, eating more or exercising more, which will immediately affect metabolism, and healthy people can return to normal level through self-regulation. However, long-term abnormal metabolism will increase the risk of basic metabolic diseases. Basal metabolism refers to the minimum power to maintain the normal operation of the human body, which will change slowly with age. About 90% of the people, the difference between the basal metabolic rate and the normal value is no more than 15%. Once it is higher or lower than 20%, it may mean that there are metabolic diseases such as thyroid dysfunction, three high, cardiovascular and cerebrovascular diseases. [characteristic prompt] the simple calculation formula of basal metabolic rate is: basal metabolic rate% = (pulse frequency + pulse pressure difference) – 111. The average value of basal metabolic rate (BMR) in Chinese adults is about 149 kJ / (m ^ 2 · h) in males and 138.6 kJ / (m ^ 2 · h) in females over 51 years old. 3. Liver type: liver cirrhosis and skin aging. The liver is an important metabolic and detoxification organ. It can decompose harmful substances absorbed by the intestinal tract or produced after metabolism by the body, and excrete them out of the body through bile or blood. Studies have shown that after 60 years of age, the number of hepatocytes decreases sharply with age. The average hepatic blood flow decreased by 1% to 25% in male patients after 50 years of age. The decrease of intrahepatic blood flow means that the liver develops to fibrosclerosis, which easily leads to the reduction of functional protein synthesis, the decline of resistance, and the serious aging of skin; the accumulation of harmful substances in various organs and tissues leads to the decline of metabolic efficiency. [characteristic prompt] there are 13 indexes in liver function test, and we mainly pay attention to 4 of them. The increase or decrease of them may reflect the existence of early liver disease. They are respectively: [transaminase] can indicate liver tissue damage. The normal values of got and GPT were 0 ~ 37U / L and 0 ~ 40u / L, respectively. The normal value of total bilirubin (TBIL) was 5.1 ~ 19 μ mol / L; albumin and globulin could reflect abnormal liver nutritional reserve. The normal values of albumin (ALB) and globulin (GRP) were 35 ~ 55g / L and 25 ~ 35g / L respectively. The levels of γ – glutamyltranspeptidase and alkaline phosphatase could reflect the secretion of digestive juice and bile duct excretion. The normal values of γ – glutamyltranspeptidase (γ – GT) and alkaline phosphatase (ALP) were 0 ~ 50U / L and 15 ~ 112u / L, respectively. 4. Kidney type: kidney failure, gout and uremia. The kidney is also an important metabolic organ. It can not only excrete harmful substances from the body, but also reabsorb some nutrients. At the same time, it is also responsible for the production of renin, erythropoietin, active vitamin D3, proactin, kinin and other hormone factors, and promote the circulation of the body. [characteristic prompt] like the liver, renal function test should pay attention to four indicators: serum urea can reflect chronic kidney disease, the normal value is 3.2 ~ 7.1 μ mol / L, if the index is too high, it may indicate that 50% of kidney tissue is damaged. Serum creatinine can reflect glomerular damage
