Expert analysis on the efficacy of sea cucumber: Sea cucumber is rich in nutrition, with protein content of 52.2%, and active substances such as sea cucumber polysaccharide account for about 15%, which is rich in sea cucumber saponins, vitamins and trace elements. Low fat content, only about 1%; No cholesterol. Sea cucumber is the best health nutrition in sea cucumber, and its main nutritional components and dietetic effects are as follows: 1. protein sea cucumber contains 18 kinds of amino acids, among which 10 kinds of amino acids necessary for human body are very high, especially arginine, which is an important component of male sperm cells and a raw material for synthesizing human collagen. It can promote cell regeneration and repair after body injury, and can also improve lymphocyte. Sea cucumber protein is mainly collagen, and its function is better than Ejiao, tortoise plastron glue and antler glue in traditional Chinese medicine. The rich glycine and basic amino acids in this collagen are the material basis for hematopoiesis, nourishing blood (biosynthesis of heme and globin) and promoting calcium absorption. A pentapeptide composed of bright, preserved, silk and arginine (partially in D configuration) contained in Arctic sea cucumber has anti-tumor and anti-inflammatory activities. Another glycoprotein is thought to be mediated by immunity, thus inhibiting the growth of transplanted tumors in animals. Second, sea cucumber is rich in sea cucumber because of its low environmental temperature and long growth period. Holothurin, also known as holothurin, contains four forms, of which Holot-hurinI is the most, and its medicinal functions are: (1) anti-tumor: holothurin has cytotoxic effect on experimental tumor cells (including human tumor strains), and some of it has been removed from oligosaccharide chain by solvents. (2) Antibacterial effect: inhibiting the growth of pathogenic bacteria (Gram-positive bacteria and Gram-negative bacteria) and pathogenic molds (Trichophyton, Mucor, Candida, Aspergillus and Trichomonas), among which the bactericidal effect of sea cucumber peptide I is particularly prominent; (3) Immune regulation and hematopoietic function: Sea cucumber has the synergistic immune activity of immune regulation and vaccine, and stimulates the growth of bone marrow red blood cells; (4) Promoting sexual function: having hormone-like activity, inhibiting ovulation and stimulating contraction; (5) Blocking neuromuscular conduction: used to prevent cerebral palsy and spasm caused by concussion and spinal cord injury; (6) Anti-fatigue effect. 3. Stichopus japonicus Mucopolysaccharides The content of polysaccharides in dry matter of Stichopus japonicus is about 65,438 05%, mainly mucopolysaccharides and Stichopus japonicus glycosaminoglycans. In addition, the sulfated oligosaccharides contained are unique to Stichopus japonicus, and their quality is better than that of polycationic components of velvet antler and fine shark fin. The effect is similar to bird's nest and chicken's gizzard-membrane, which are highly praised by Chinese medicine for invigorating qi and benefiting middle energizer, treating deficiency and tonifying deficiency. The main functions of sea cucumber polysaccharide are as follows: (1) Anti-cancer: Sea cucumber mucopolysaccharide can resist the growth of tumors in many experimental animals, and the growth inhibition rates of MA-737 breast cancer and T795 lung cancer are as high as 79% and 60% respectively, and it can also inhibit the artificial lung metastasis of M737 breast cancer and the natural metastasis of Lewis lung cancer; (2) Enhancing immunity: Stichopus japonicus mucopolysaccharide can improve the cellular immune function of the body, and improve and enhance the immune hypofunction of animals caused by tumor bearing or using anticancer drugs; (3) Antithrombotic and hypoglycemic: Stichopus japonicus mucopolysaccharide can inhibit the formation of blood embolism and improve the survival rate of animals. Stichopus japonicus mucopolysaccharide can reduce the blood viscosity and plasma viscosity of normal middle-aged and elderly people (48-72), and also has the function of regulating blood lipid, that is, reducing serum cholesterol and triglyceride levels, increasing apolipoprotein A and reducing apolipoprotein B; (4) Anti-aging: In the experiment of rat cortical neurons cultured in vitro with Stichopus japonicus mucopolysaccharide carrier, it has obvious effect on cortical neurons injury or apoptosis induced by amyloid β protein, and this kind of polysaccharide can prevent degeneration of central neurons, such as Alzheimer's disease; (5) Antivirus: Stichopus japonicus mucopolysaccharide can resist the specific pathological changes of tissue culture cells caused by herpes simplex virus (HSV); Stichopus japonicus glycosaminoglycan significantly inhibited the infection rate of HIV to cultured cells; In addition, in the preliminary clinical experiment, it was confirmed that Stichopus japonicus mucopolysaccharide had better effects on three positive factors of chronic hepatitis patients, namely Hb-sAg, HbeAg, anti -HBc negative conversion and liver function recovery than conventional drugs. (6) Radiation resistance: it can protect animals irradiated by C _ (60) O and promote the recovery of their hematopoietic function; (7) Stichopus japonicus mucopolysaccharide can prevent osteoporosis and can be used to treat arthritis. 4. Fat, vitamins and minerals nutrition Although the fat content of sea cucumber is low, the human body must contain fatty acids arachidonic acid and EPA, accounting for more than 50% of the total. Sea cucumber mainly contains vitamins A, B, D and E. Sea cucumber contains a lot of mineral nutrients, such as calcium, magnesium, manganese and silicon, among which organic calcium is rich, so it is a natural calcium-supplementing food.
