Honey has the effect of moisturizing the skin. It is used to skin care to make the skin smooth and supple. The following Xiao Bian will introduce honey beauty to everyone from the effects of honey. 1, clean the skin Honey has a strong bactericidal anti-inflammatory effect, apply a small amount of honey or honey and other accessories formulated beauty products, can effectively inhibit the skin surface bacterial infection and survival, so as to play a role in protecting the skin, clean the skin, help keep the skin clean and smooth , glossy and exuberant activity. 2, nourish the skin Honey has strong moisturizing ability, can absorb the moisture in the air, not only can better prevent evaporation of water evaporation on the surface of the epidermis, under specific conditions, but also to supplement the skin moisture required for honey has an amazing permeability, which Youth protection face has a positive effect, not only makes some nutrients can be successfully penetrated into the skin is effectively absorbed and utilized, but also form a protective film on the surface, not only play a role in conservation, but also play a role in moisture and isolation. Especially when the winter climate is dry, honey prevents skin chapping. 3, improve skin quality The nutrients of honey are all natural nutrients. Its bioactive substances such as monosaccharides, vitamins and enzymes are conducive to absorption by skin cells, can effectively improve the nutritional status of the skin surface, make the skin delicate, maintain natural rosy, and It helps to delay the aging of skin cells, which can delay or reduce wrinkles. The effect of honey on skin care is more or less known to us. Bathing with honey can make the skin moisturized and become soft and elastic. In addition, shampooing with honey-containing products can make the scales slippery and replenish nutrients. Makes hair soft and shiny. In addition, honey can effectively remove bacteria and luster on the skin surface, thereby reducing acne, spots, etc. caused by bacteria. With the natural exfoliating particles such as oat kernels, it can completely remove the aging skin of the skin surface without any stimulation. There are two ways to eat honey: One is to use cold boiled water, so that the vitamin C oxidase in honey will not be destroyed, summer blunt also has the role of relieving summer heat, detoxifying and laxative; The second is to use warm boiled water (40 degrees) to blunt, this can play a role in supplementing the benefits of Qi, it will not destroy a variety of nutrients. However, in daily life, many people are accustomed to using high temperatures or boiled water to brew honey, but this practice is unscientific. Because of this, the substances and parts of the vitamins in the honey are destroyed, resulting in an excess of hydroxymethyl aldehydes, which greatly damages the nutrients of the honey. In addition, hot water boiled honey will also inactivate the enzymes in the honey, the color will become darker, the flavor will evaporate, the taste will change, and the food will have unpleasant sourness. This is also the main reason why pure natural honey is better than processed honey. Because the first step in the processing of honey is to distill the pure honey collected from the bee plant at a low concentration to a high temperature of 42 degrees and 43 degrees. However, high temperature damage to nutrients in honey is enormous. Be careful with honey's food (1) Honey should not be soaked in milk Protein content is higher than that of milk, and honey contains mainly about 75% glucose and fructose, and also contains a small amount of organic acids. When the two are flushed, organic acids and proteins combine to produce degenerate precipitates that cannot be absorbed by the body. (2) Honey should not be the same as tofu Tofu is sweet, salty, cold, and can dissipate heat and blood. Foods with honey can cause diarrhea. At the same time, various enzymes in honey, various minerals in tofu, plant proteins, organic acids, etc., both of which are not conducive to the human body's biochemical reactions. (3), honey should not be the same with leeks Leek is rich in vitamin C, and is easily oxidized by the minerals such as copper and iron in honey and lose its effect. In addition, honey can be lax, leek rich in cellulose and cathartic, it is easy to cause diarrhea. The automatic biochemical analyzer is an instrument that measures a specific chemical composition in body fluids according to the principle of photoelectric colorimetry. Due to its fast measurement speed, high accuracy and small consumption of reagents, it has been widely used in hospitals, epidemic prevention stations and family planning service stations at all levels. The combined use can greatly improve the efficiency and benefits of routine biochemical testing.

principle
The automatic analyzer is to automatically run all or part of the steps of sampling, mixing, warm bath (37°C) detection, result calculation, judgment, display and printing results and cleaning in the original manual operation process. Today, biochemical tests are basically automated analysis, and there are fully automatic biochemical analysis systems designed for large or very large clinical laboratories and commercial laboratories, which can be arbitrarily configured according to the laboratory's testing volume.
Whether it is the fastest-running (9600Test/h) modular fully automatic biochemical analyzer today, or the original manual-operated photoelectric colorimeter for colorimetry, the principle is the use of absorption spectroscopy in spectroscopic technology. It is the most basic core of the biochemical instrument.
Optical system: is a key part of ACA. Older ACA systems used halogen tungsten lamps, lenses, color filters, and photocell assemblies. The optical part of the new ACA system has been greatly improved. ACA's beam splitting system can be divided into front splitting and rear splitting due to different light positions. The advanced optical components use a set of lenses between the light source and the cuvette to convert the original light source. The light projected by the lamp passes through the cuvette to bring the beam to the speed of light (unlike traditional wedge beams), so that the spot beam can pass through even the smallest cuvette. Compared with traditional methods, it can save reagent consumption by 40-60%. After the spot beam passes through the cuvette, the spot beam is restored to the original beam through this group of restoration lenses (wide difference correction system), and is divided into several fixed wavelengths (about 10 or more wavelengths) by the grating. The optical/digital signal direct conversion technology is used to directly convert the optical signal in the optical path into a digital signal. It completely eliminates the interference of electromagnetic waves to the signal and the attenuation in the process of signal transmission. At the same time, the optical fiber is used in the signal transmission process, so that the signal can achieve no attenuation, and the test accuracy is improved by nearly 100 times. The closed combination of the optical path system makes the optical path without any maintenance, and the light splitting is accurate and the service life is long.
Constant temperature system: Since the temperature of the biochemical reaction has a great influence on the reaction results, the sensitivity and accuracy of the constant temperature system directly affect the measurement results. The early biochemical instruments used the method of air bath, and later developed into a dry bath with constant temperature liquid circulation which combines the advantages of dry air bath and water bath. The principle is to design a constant temperature tank around the cuvette, and add a stable constant temperature liquid that is odorless, non-polluting, non-evaporating and non-deteriorating in the tank. The constant temperature liquid has a large capacity, good thermal stability and uniformity. The cuvette does not directly contact the constant temperature liquid, which overcomes the characteristics of the water bath type constant temperature being susceptible to pollution and the uneven and unstable air bath.
Sample reaction stirring technology and probe technology: The traditional reaction stirring technology adopts magnetic bead type and vortex stirring type. The current popular stirring technology is a stirring unit composed of multiple groups of stirring rods that imitate the manual cleaning process. When the first group of stirring rods is stirring the sample/reagent or mixed solution, the second group of stirring rods performs high-speed and high-efficiency cleaning at the same time. The set of stirring bars also undergoes a warm water washing and air drying process at the same time. In the design of a single stirring rod, a new type of spiral high-speed rotating stirring is adopted, and the rotation direction is opposite to the spiral direction, thereby increasing the stirring force, the stirred liquid does not foam, and reducing the scattering of light by microbubbles. Reagent and sample probes are based on the principle of early capacitive sensing, but slightly improved to increase the alarm of blood clots and protein clots, and re-test results according to the alarm level, reducing sample aspiration errors and improving the reliability of test results. . Large-scale biochemical instruments can detect more than 1,000 tests per hour, so automatic retesting is very important. Subjective evaluation of test results and manual retesting can no longer meet clinical needs.
Other aspects: barcode recognition of reagents and samples and computer login. Due to the lack of barcode recognition function of early biochemical instruments, there are more opportunities for errors. In recent years, both imported and domestic chemical instruments have adopted barcode detection. The use of this technology in biochemical instruments has provided technical support for the development of high-speed ACA, and also made the instrument quite supportive. The software development is simple and easy, therefore, barcode detection is the basis for the intelligence of the instrument. Open reagents, as an important factor for hospitals to choose models, whether the instrument supports open reagents is very important. After the reagents are opened, hospitals and scientific research units can choose their own reagent suppliers, and have a greater degree of freedom in measuring the price, the reliability of the test results, and the validity period of the reagents. Ion Selective Electrode Analysis Accessory (ISE), human serum and urine electrolyte indicators are very important, and hospitals can save money by adding ISE to the ACA system.
