Theoretical basis: 1: ferritin is a soluble tissue protein used to store iron in the body. Normal human serum contains a small amount of ferritin, but different detection methods have different normal values. Generally speaking, the normal average value of men is about 80- 130 μ g/L (80- 130 ng/mL), and that of women is 35-55 μ g/L (35-55 ng/mL).
Reasons for high ferritin:
1, liver diseases, such as liver necrosis, chronic liver diseases, liver cirrhosis, liver tumors, etc. , are the reasons for high ferritin.
2, too much iron load, such as primary hemochromatosis, repeated blood transfusion, improper iron treatment, etc. It also belongs to the reason of high ferritin.
3, sideroblastic anemia, aplastic anemia, megaloblastic anemia, hemolytic anemia, etc. These are the reasons for high ferritin.
4. Cancer, such as liver cancer, pancreatic cancer and lung cancer, is also the cause of high ferritin. The main reasons of high ferritin in hepatocellular carcinoma are as follows: ① Hepatocarcinoma cells can synthesize and secrete ferritin or isoferritin. ② The uptake and clearance of ferritin in liver cancer tissues were affected. ③ Damage and necrosis of liver cells are also the causes of high ferritin, and ferritin stored in the cytoplasm of liver cells overflows into the blood and causes high ferritin.
5, inflammation or infection, hyperthyroidism, etc. It's all about the methemoglobin.
Theoretical basis 2:
(Tea Tea) Green tea, one of the main tea leaves in China, refers to a drink made from new leaves or buds of tea trees without fermentation, and then through the processes of deactivation, shaping and drying. The color of the finished product and the brewed tea soup retain the green style of new tea. Drinking green tea regularly can prevent cancer, reduce fat and lose weight, and also reduce the harm of nicotine to smokers.
Without fermentation, green tea retains the natural substances of fresh leaves, and contains many nutrients such as tea polyphenols, catechins, chlorophyll, caffeine, amino acids and vitamins. These natural nutrients in green tea have special effects of anti-aging, anti-cancer, sterilization and anti-inflammation, which are beyond the reach of other teas. Green tea is a kind of tea made from suitable new shoots of tea trees through typical technological processes such as enzyme fixation, rolling and drying. Its dry tea color and brewed tea soup and tea leaves are mainly green, hence the name green tea. Green tea is made by deactivating fresh leaves at high temperature, killing various oxidases, keeping tea green, and then rolling and drying. Clear soup and green leaves are the same characteristics of green tea quality.
Green tea is called "national drink" in China. A large number of studies in modern science have confirmed that tea does contain biochemical components closely related to human health. Tea not only has the pharmacological effects of refreshing brain, clearing away heat and relieving summer heat, resolving food stagnation, relieving fatigue and losing weight, clearing away heart fire and vexation, relieving hangover, promoting fluid production to quench thirst, reducing fire and improving eyesight, stopping dysentery and removing dampness, but also has certain pharmacological effects on modern diseases such as radiation sickness, cardiovascular and cerebrovascular diseases and cancer. The main components with pharmacological effects in tea are tea polyphenols, caffeine, lipopolysaccharide, theanine and so on. The specific functions are:
1, anti-aging
It is helpful to delay aging. Tea polyphenols have strong antioxidant and physiological activity, and are free radical scavengers in human body. Studies have proved that 1 mg tea polyphenols is equivalent to 9 micrograms of superoxide dismutase in scavenging excessive free radicals harmful to human body, which is much higher than other similar substances. Tea polyphenols can block lipid peroxidation and remove active enzymes. According to the test results of Tomoyo in Ota, Japan, it is confirmed that the anti-aging effect of tea polyphenols is 18 times stronger than that of vitamin E.
2. Suppress diseases
Tea polyphenols can inhibit cardiovascular diseases and play an important role in human fat metabolism. The human body has cardiovascular diseases such as high cholesterol and triglycerides, such as fat deposition on the inner wall of blood vessels and atherosclerotic plaques formed after vascular smooth muscle cells proliferate. Tea polyphenols, especially catechins ECG and EGC in tea polyphenols and its oxidation products theaflavins, are helpful to inhibit this mottled proliferation, reduce the formation of fibrinogen that enhances coagulation viscosity, make coagulation clear, and thus inhibit atherosclerosis.
3. Anti-cancer
Helps prevent and fight cancer. Tea polyphenols can block the synthesis of carcinogens such as ammonium nitrite in the body, which can directly kill cancer cells and improve the immunity of the body. According to relevant data, tea polyphenols in tea are beneficial to the prevention and adjuvant treatment of cancers such as gastric cancer and intestinal cancer.
4. Antiviral bacteria
Tea polyphenols have strong convergence, obvious inhibition and killing effects on pathogenic bacteria and viruses, and obvious anti-inflammatory and antidiarrheal effects. Many medical units in China use tea preparation to treat acute and chronic dysentery, amebic dysentery and influenza, and the cure rate is about 90%.
5. Beauty and skin care
Tea polyphenols are water-soluble substances, which can remove greasy face and astringe pores, and have the effects of disinfection, sterilization, anti-aging and reducing the damage of ultraviolet rays in the sun to the skin.
6, refreshing.
Caffeine in tea can stimulate the central nervous system of human body, enhance the excitement process of cerebral cortex, and has the functions of refreshing the brain, clearing away heart fire and calming the nerves. It also has a certain effect on relieving migraine.
6, diuresis to relieve fatigue
Conducive to diuresis and relieve fatigue. Caffeine in tea can stimulate the kidney, promote the rapid excretion of urine, improve the filtration rate of the kidney and reduce the retention time of harmful substances in the kidney. Caffeine can also eliminate excessive lactic acid in urine, which helps to eliminate fatigue as soon as possible.
7. Relieve fatigue
Green tea contains powerful antioxidants and vitamin C, which can not only eliminate free radicals in the body, but also secrete hormones against stress. A small amount of caffeine contained in green tea can stimulate the central nervous system and cheer up the spirit. Because of this, we suggest drinking green tea in the morning to avoid affecting sleep.
8. Tooth protection and eyesight
The fluorine content in tea which is helpful for protect teeth and improving eyesight is very high, and that fluorine content per100g of dry tea is10mg-15mg, of which 80% is a water-soluble component. If everyone drinks 10g tea every day, they can absorb 1mg- 1.5mg of water-soluble fluoride. Moreover, tea is an alkaline beverage, which can inhibit the reduction of calcium in the human body, help prevent dental caries, protect teeth and strengthen teeth. The experiment of "gargling tea after drinking" among primary school students can reduce the incidence of dental caries by 80%. Among cataract patients, 28.6% have the habit of drinking tea; 7 1.4% have no habit of drinking tea. This is because vitamin C and other ingredients in tea can reduce the turbidity of eyes, and drinking tea often has a positive effect on reducing eye diseases, protecting eyes and improving vision.
9. Reduce blood lipids
Helps to lower blood fat and help digestion. In the Tang Dynasty's Herbal Supplement, it was recorded that the effect of tea was "to lose weight after eating for a long time". There is a saying among the ethnic minorities in China's border areas that "tea is indispensable for a day". Because tea helps digestion and reduce fat, in today's fashionable language, it is helpful to "lose weight". This is because caffeine in tea can increase gastric juice secretion and help digestion. In addition, green tea is rich in catechins, which helps to reduce abdominal fat.
