Detailed Description
Embodiments of the present invention will be described in detail with reference to the following examples, but those skilled in the art will understand that the following examples are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention, and that the specific conditions not specified in the examples are carried out according to conventional conditions or conditions suggested by the manufacturer, and that the reagents or equipment used are not specified by the manufacturer, and are all conventional products available through commercial purchase.
The technical scheme of the embodiment is as follows:
a composition with liver and stomach protecting effects mainly comprises the following raw materials in parts by weight:
35-98 parts of alpha-lactalbumin, 0.5-40 parts of inulin, 0.5-10 parts of camel milk, 0.3-5 parts of osteopontin and 0.3-4 parts of casein glycomacropeptide.

Among them, alpha-lactalbumin is the most typical dietary tryptophan source, and serotonin (5-HT) is a neurotransmitter synthesized by tryptophan (Trp) and found primarily in the gastrointestinal and Central Nervous Systems (CNS). Serotonin content in the brain is involved in mood, alertness, sleep patterns, stress resistance, depression and appetite and is an important regulator of mood and appetite. The alpha-lactalbumin can ensure positive emotion and appetite while providing high-quality nutrition, and is an optimal solution for people with insufficient liver functions, particularly people with alcoholic liver diseases and chronic hepatitis. Meanwhile, cysteine provided by the alpha-lactalbumin is one of three essential amino acids for synthesizing glutathione. The rate of glutathione production depends on the intracellular cysteine content. Cysteine is a rate-limiting factor affecting glutathione synthesis, since the cysteine content in our diet is relatively insufficient and the part of cysteine containing sulfur molecules is the main reason for the biological activity of glutathione production.
Glutathione plays an important role in the human body as follows: (1) support the normal function of the immune system: during the course of the immune response, lymphocytes are constantly replicating and producing antibodies, and it is necessary to ensure adequate glutathione levels in lymphocytes. (2) Antioxidant free radical scavenger: glutathione plays an extremely important role in combating damage caused by contaminants such as bacteria, viruses, carcinogenic sources, and free radicals. (3) Regulation of other antioxidants: without glutathione, other antioxidants such as vitamin C and E do not perform their antioxidant effects properly. VC and VE are one of the traditional methods for clinically treating alcoholic liver injury. (4) Antidote: another important function of glutathione is the detoxification of exogenous chemicals (alcohol, intermediate metabolites of drugs, harmful metals, etc.).
For alcoholic liver disease, alcohol is metabolized to acetaldehyde in hepatocytes primarily by alcohol dehydrogenase in the cytosol, P450 enzymes in the microbody, and catalase in the superoxide proteasome. Acetaldehyde, a highly active substance, can react with various proteins and DNA, and also accelerates glutathione depletion, lipid peroxidation and mitochondrial damage, and has strong hepatotoxicity. Therefore, supplementation with exogenous glutathione contributes to liver function protection following alcohol consumption. During the action of alcohol dehydrogenase and acetaldehyde dehydrogenase, glutathione protects-SH group in enzyme molecule, is favorable for the exertion of enzyme activity, and can recover the activity function of-SH group in damaged enzyme molecule, so that the enzyme recovers activity again. In addition, glutathione can combine with ethanol metabolite acetaldehyde and oxygen free radical, inactivate it and accelerate free radical excretion, inhibit or reduce liver cell membrane and mitochondrial membrane peroxidized liposome formation, and protect liver cell. Meanwhile, glutathione can maintain liver protein synthesis through gamma-glutamic acid circulation. In the clinical observation of reducing glutathione for treating alcoholic liver diseases, the supplement of 1.8g of glutathione can reduce the indexes of glutamic-oxaloacetic transaminase AST and glutamic-pyruvic transaminase ALT by 60 percent, and the clinical symptoms are obviously relieved. Therefore, the alpha-lactalbumin can promote the restoration of liver functions by promoting the production of glutathione, and is beneficial to the treatment of liver diseases, particularly alcoholic liver diseases.
Meanwhile, the alpha-lactalbumin also has good repairing function on gastric mucosa. The defense mechanism of the alpha-lactalbumin affecting the gastric mucosa is mainly as follows: (1) activation of prostaglandin synthesis: prostaglandins, especially prostaglandin E2, have a strong antiulcer effect and play a key role in the gastric mucosal defense system. (2) Stimulation of mucus and bicarbonate secretion: increasing the amount of mucus in the gastric cavity prevents consumption of the gastric mucus gel layer, and reduces the damage to the gastric mucosa caused by the mechanical forces of digestion; bicarbonate ions neutralize the acid in the stomach cavity and hydrogen ions that flow back into the gastric mucus gel layer. (3) Increasing the gastric juice volume: diluting toxic factors, such as ethanol. (4) Inhibition of gastric motility (emptying and contraction): excessive contraction, i.e., increased gastric contraction, is the major pathogenic mechanism of necrosis factor and stress induced ulceration.
Gastric mucin is the major component of gastric mucus, imparting the adhesive, elastic, colloidal properties to gastric mucus. The layer of gastric mucus gel that adheres to the gastric mucosa is a barrier that protects the gastric mucosa. It coats the gastric mucosal surface, binding bicarbonate ions to neutralize hydrogen ions in the colloidal layer. Alpha-lactalbumin promotes synthesis and secretion of mucin by mucus-producing cells, causing an increase in the thickness of the mucus colloid layer, thereby increasing the content of mucin in gastric juice and gastric mucus.
Inulin, a natural water-soluble dietary fiber, is hardly hydrolyzed and digested by gastric acid and is utilized only in the colon by beneficial microorganisms, thereby improving the intestinal environment. Beneficial bacteria can be utilized in intestinal tracts, particularly bifidobacterium can be proliferated by 5-10 times, and meanwhile, harmful bacteria can be obviously reduced, so that the distribution of human flora is improved, and the health is promoted. Secondly, after the inulin is ingested, the gastrointestinal peristalsis can be enhanced, the gastrointestinal function can be improved, the digestion and the appetite can be increased, and the organism immunity can be improved. Therefore, the inulin can be used as a bifidobacterium proliferation factor, so that the composition has better functions of protecting liver and stomach.
Compared with common milk, the camel milk has better nutritive value, is rich in vitamin C, and also contains a large amount of unsaturated fatty acid, iron and vitamin B which are required by human bodies. Warm in nature, sweet in taste, cold and non-toxic. Has effects in invigorating spleen, replenishing qi, and strengthening tendons and bones.
Whey protein is a protein extracted from milk, and is called "the king of protein" due to its advantages of high purity, high absorption rate, most reasonable amino acid composition, etc. The whey protein is not only easy to digest, but also has high biological value, high digestibility, high protein efficiency ratio and high utilization rate, is a fine product in protein, is one of accepted high-quality protein supplements for human bodies, and has the content of only 0.7 percent in milk. In addition, the food derived from animal protein contains harmful substances such as excessive saturated fat and cholesterol which are harmful to human body, and excessive eating of the food can easily cause the increase of the fat and cholesterol of the human body, thereby causing the occurrence of cardiovascular diseases. Therefore, the composition can be supplemented with whey protein to prevent the above diseases while supplying high-quality protein.
Osteopontin, also known as OPN whey protein, is a glycosylated protein that is widely found in the extracellular matrix. Osteopontin is present in very high amounts in breast milk (on average about 138mg/L) and is an important immunologically active protein in breast milk. Glycosylation modification of OPN is based on O-glycans, in which the sialylation ratio is high, and may therefore also be referred to as sialoglycoproteins. The activity of osteopontin can directly reach the intestinal tract, the intestinal tract protection and barrier function is enhanced, and the whole body immune protection is realized.
Casein glycomacropeptide, also known as CGMP whey protein, has a protective effect on intestinal barriers. CGMP is used as a signal molecule to realize the regulation of the immune process of the intestinal mucosa of the organism through which immune signal pathway; CGMP has the ability to maintain intestinal mucosal immunity homeostasis. The CGMP is added into the composition, so that the composition can maintain the immunity and self-stability of intestinal mucosa of an organism, thereby effectively regulating and maintaining the internal environment of an intestinal tract and playing a role in repairing and protecting the gastrointestinal tract.
The milk mineral salt is a nutritional supplement which is prepared by taking whey as a raw material and removing protein, lactose and other components of milk basic protein and is beneficial to absorption of a human body. The milk mineral salt contains abundant minerals, mainly calcium and phosphorus, and can be used as food enhancer and nutritional supplement. In this embodiment, the milk mineral salt used is purchased from the company of Bifen, Daiichi, Inc.
The rose pollen mainly comprises carbohydrates, amino acids, proteins, vitamins, organic acids, mineral substances and the like, and also contains rich anthocyanin, flavonoid compounds, carotene, tannin and other components, wherein the most representative components are vitamin C and flavonoid compounds. Vitamin C has strong antioxidation and is helpful for eliminating free radicals in vivo, and flavonoids have remarkable effects in resisting bacteria and inflammation, reducing blood fat and lowering blood pressure, etc. Therefore, the rose pollen is added into the composition due to the effects of regulating qi and blood, soothing liver and resolving depression, so that the flavor of the composition is improved, and the protective effect on the liver can be enhanced.
The following describes in detail specific embodiments of the present invention. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

Experimental example two
Experimental study on composition for promoting liver function recovery after liver injury
Firstly, an experimental process:
1 materials and methods
1.1 materials: clean grade male rats 32, weighing 250g,
1.2 experimental grouping: the normal group was administered with physiological saline by the same intraperitoneal and subcutaneous route, and the control group was established as a liver injury model while the DMSO (n ═ 12) treatment group was administered daily with the liver and stomach protecting composition (n ═ 12) provided in example 8 dissolved in DMSO based on the liver injury model.
1.3 liver injury model: thioacetamide (TAA) was dissolved in physiological saline and 100mg/kg of TAA solution was intraperitoneally injected to each rat 1 time/day for 7 consecutive days.
1.4 dosing and observation treatment groups functional liver whey protein nutrition was given Id before the start of modelling, 1 dose every 24 h. TAA was injected intraperitoneally while a control group was injected subcutaneously with 0.2ml/(kg-d) DMSO' or 60mg/(kg d) of the composition for protecting liver and stomach provided in example 8 of the present invention, the solvent was 0.2ml/(kg d) DMSO, and a normal group was administered with the same intraperitoneal and subcutaneous routes as those of normal group with the same amount of physiological saline. Animals were observed 2 times daily and rat body weight and general status were recorded.
1.5 liver function assay
After stopping the injection of the TAA solution for 36h, blood was taken via the inferior vena cava under ether anesthesia and heparin was anticoagulated. The obtained blood was centrifuged at 1500rpm and immediately examined, and ALT, AST, TBIL' DBTIL, 7-GT, ALP, TBA, LDH indexes were detected by enzyme method on a Hitachi 7600 automatic analyzer.
1.6 pathological examination
Fixing the liver in 4% paraformaldehyde, conventionally embedding, flaking, HE staining, and observing the shape of the liver cell under a light microscope.
1.7 other laboratories regularly irradiated with UV light, the syringe needle and the ready-prepared drug were kept sterile to exclude the effect of infection on the experiment.
2 results
2.1 in the liver-protecting and stomach-protecting composition, the fatality rate of the liver injury of rats is reduced in the model establishment process, 4 rats in a control group die (33.33%), no death occurs in a treatment group and a normal group, and the fatality rate of the control group is obviously higher than that of the treatment group and the normal group (P < 0.05). Compared with the rats in the normal group, the rats in the control group and the treatment group have obvious weight loss (P <0.001), the weight of the normal group is obviously heavier than that of the treatment group and the control group on the 4 th day of the model (the normal group (263 +/-7.95) g, the treatment group (223.42+10.00) g, the control group (216 +/-6.95) g and P <0.001), and the weight of the treatment group is obviously higher than that of the control group (P < 0.05). At the end of the experiment (day 9), the weight of the normal group was highest (normal group (263.63 + -15.82) g, treatment group (220.17 + -12.62) g, control group (208.43 + -9.61) g, P <0.001), and the weight of the treatment group was still higher than that of the control group (P < 0.05). The rats in the control group had significantly depressed spirit compared to the treated group.
2.2 in the liver and stomach protecting composition, liver function is recovered and liver damage is recovered, the normal group and the treatment group have obvious difference (P <0.01) on indexes such as AST, TBIL, 7-GT, ALP, TBA and the like, but have no significance (P >0.05) on indexes such as ALT and LDH. There were different degrees of differences in the ALT, TBIL, ALP, TBA, LDH indices between the control and treated groups (P <0.05), but no significant differences in the AST, 7-GT indices (P > 0.05).
2.3 pathological observation after HE staining, the conditions of liver cell degeneration, necrosis, inflammatory cell infiltration and the like in the recovery period are observed, and the cell morphology of a control group, a treatment group and a normal group has no obvious pathological change except the local accidental cell degeneration change of the control group.
The experiment shows that the liver and stomach protecting composition provided by the application can obviously reduce the fatality rate of rats with liver injury. Although the weight of the rats in the treatment group is reduced compared with that in the normal group, the weight of the rats in the treatment group is obviously better than that in the control group, and the protection effect of the rats on the liver function is indirectly reflected. In the experiment, the liver function indexes of the treatment group are better than those of the control group after the liver and stomach protecting composition is used. TAA is an acute hepatotoxic compound, and after administration is stopped for 14h, liver function can be gradually recovered, which is shown by the decrease of liver injury markers such as ALT. In the experiment, the liver functions of 3 groups are recovered 36h after continuous liver injury is stopped, wherein the treatment group and the normal group have no obvious difference on ALT and LDH indexes, while the control groups ALT, TBIL, ALP, TBA and LDH are obviously higher than the treatment group, and TBA and ALT are taken as the significant indexes, namely the liver function recovery is slower than that of the treatment group, which prompts that the liver and stomach protecting composition plays a role in promoting the recovery of the liver function after the liver injury.
Previous experiments have demonstrated that whey proteins have a variety of effects, improving and reducing oxidative stress in the liver, reducing DNA damage caused by oxidation and oxidation of membrane proteins, stabilizing cell membranes, increasing the activity and expression of liver antioxidant enzymes, synergistically eliminating free radicals [ 2, 3 ], reducing the expression and activity of inflammatory mediators such as neutrophil chemokines, IL, adhesion molecules [ 4, 5 ], and combating fibroblast proliferation by affecting mRNA, EGF, nf.kb, cell cycle [ 6-8 ]. TBA, TBIL and ALT are main indexes for prompting hepatocyte damage, TBIL reflects cell damage and bilirubin metabolic disorder after hepatocyte damage, TBA reflects hepatocyte function, and ALT exists in hepatocyte, and are increased when hepatocyte is damaged.
TBA, TBIL and ALT of rats in a treatment group in the experiment are all obviously lower than those in a control group, so that the rats in the treatment group are less damaged by hepatic cells and relatively good in liver function, and the liver and stomach protecting composition provided by the application can reduce the damage of the hepatic cells, promote the recovery of the liver function after the hepatic cells are damaged and protect the damaged hepatic cells.
In addition, LDH, ALP and AST are also increased in acute liver injury, and the LDH, ALP and AST results of the experiment also reflect the liver protection effect of the liver and stomach protection composition. Oxidative stress, inflammatory reaction and the like are initial reasons causing liver cell damage, the liver damage of a treatment group rarely reflects the antioxidant stress and the anti-inflammatory action of the liver and stomach protecting composition, and the action mechanism is consistent with the results of reducing the liver damage and promoting the recovery of the liver function.
Finally, it should be noted that: the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
