Composition for recovering patients with liver diseasesTechnical Field
The invention belongs to the technical field of formula foods for special medical purposes, and particularly relates to a composition for recovering patients with liver diseases.
Background
Liver diseases are common diseases and frequently encountered diseases in China, and can be generally divided into viral hepatitis, alcoholic liver diseases, drug-induced liver injury, fatty liver, liver cirrhosis, liver cancer and the like. The '2017 world hepatitis report' issued by world health organization of 21/4/2017 shows that about 3.25 million people are infected with chronic hepatitis B virus or hepatitis C virus worldwide. 2016 liver disease research report states that chronic hepatitis B causes over 33 million cancer-related deaths each year in China. The incidence of hepatitis C is second to that of hepatitis B, and accounts for 17.06 percent of the total incidence of viral hepatitis. The incidence of 'rich and noble diseases' such as alcoholic liver, fatty liver and the like is also improved year by year, and by the end of 2010, the incidence of the total non-alcoholic fatty liver disease in China is about 15%, the incidence of the non-alcoholic fatty liver disease in the first-line city is close to the developed country in the west and reaches 20% -30%, and the incidence of the fatty liver disease in the severely obese people reaches 61% -94%. According to the calculation, at least 2 hundred million people have fatty liver disease in China, and the number of people who convert fatty liver disease into hepatic fibrosis and hepatic cirrhosis is about 400-. The situation of alcoholic liver disease is very severe and can not be ignored, and by 2011, the conservative estimation is that the number of patients suffering from alcoholic liver disease in China is about 5000 ten thousand.
The liver, the most important substance in the body and the energy metabolism organ, plays an important role in the metabolism of sugar, lipid, protein, amino acid, vitamin, hormone and other substances. When liver is damaged by various reasons (viruses, alcohol, etc.), the energy metabolism of the body can be obviously changed. Therefore, patients with liver diseases are very likely to suffer from malnutrition. Ismail et al found in a 400-patient control study that Chronic Hepatitis C (CHC) patients had malnutrition prior to the development of cirrhosis. Mengqinghua et al found in the REE study of 142 Chronic Hepatitis B (CHB) patients: the incidence of malnutrition in CHB patients was 14.10%, with 15.49% of patients being hypermetabolized, 47.18% being normal, and 37.32% being hypometabolized. In the cirrhosis compensation phase, up to 50-80% of patients are complicated by malnutrition of different degrees. In the decompensation phase of cirrhosis, nearly 100% of patients are complicated by malnutrition. The causes of malnutrition in patients with liver disease include reduced food intake, reduced nutrient absorption, increased nutrient loss, high metabolic state, and insufficient synthesis. The degree of malnutrition in patients with liver disease directly affects the prognosis of the patient.
Therefore, the nutritional support is an important part of the comprehensive treatment of patients with liver diseases, and under the condition of ensuring that the carbohydrate is ingested to supply enough calories, the chronic hepatitis patients should be rich in protein and proper amount of fat, and simultaneously should not neglect to supplement proper amount of B vitamins and fat-soluble vitamins such as vitamin A, D, E and trace elements of calcium, magnesium, zinc, selenium and the like so as to supplement the loss of the trace nutrients caused by the damage of liver cells. Patients with liver cirrhosis, the European society for intestinal and intestinal nutrition (ESPEN) and the American society for intestinal and intestinal nutrition (ASPEN) both recommend a dietary intake pattern of few meals and more meals, preferably 4 to 6 meals per day. The energy intake standard is 35-40 kcal/kg/d), and the protein intake is 1.2-1.5 kcal/kg/d). For patients with liver failure, the protein is not suitable to be used as an energy supply substance, and is suitable to be used as a source supplement of a liver tissue repair substance, and the supply amount is 1.5-2.0 g/kg/d); 0.8-1.5 g/kg/d) of amino acid, and in severe hepatic encephalopathy, the branched chain amino acid is supplemented into veins, and the changes of indexes such as blood ammonia and the like are closely monitored, so that the nutrition supply scheme is adjusted at any time. Proper amount of B vitamins, vitamin A, C, D, E, K and minerals such as potassium, magnesium, calcium, zinc, phosphate, etc.
At present, the number of enteral nutrition products for patients with liver diseases in China is very small, and the patients with critical liver diseases are often accompanied by complications such as nephropathy and diabetes, and the enteral nutrition products are not considered in the formula of the existing products.

Protection effect on acute alcoholic liver injury of rat
Test compositions: example 3 and comparative example 1.
The test method comprises the following steps: the SPF-grade male SD rat of 6-8 weeks old has the body mass of 180-. From day 15, the composition was administered 1h later for the remaining groups except for the normal control group to which distilled water and maintenance diet were administered, and then the composition was administered 2 times with 50% ethanol gavage, 2 molding intervals of 6h, and high-fat diet feeding was continued for 7d, in order to show successful molding of the clinical manifestations and pathological changes of ALD: (1) changes in animal behavior occurred: listlessness, inappetence, loose stool, fluffy and lusterless fur, unstable walking, mouth scratching of the front paw and rigid action; (2) liver function index abnormality: the AST and ALT levels of the serum are obviously higher than those of a normal control group; (3) pathological dissection of animals: the liver surface has the changes of spots, swelling and the like; (4) pathological section: inflammatory infiltration of liver tissue or accumulation of fat droplets in hepatocytes, etc.
Fasting without water for 16h after the last model building, taking blood from abdominal aorta, separating serum, and measuring AST and ALT levels with full-automatic biochemical analyzer.
Before the rat is sacrificed, the mental state, the food intake, the excrement and urine, the body hair, the activity condition and the like of the rat are observed and recorded, the mass of the rat body is weighed and recorded, and the liver coefficient is calculated.
And (3) test results:
(1) the normal control group rats have no abnormal change in general conditions, the model group rats have gradually reduced food intake and water intake, and the phenomena of inappetence, loose stool, fluffy and lusterless fur, listlessness, unstable walking, mouth scratching of front claws, dull movements and the like begin to appear. The rats in the group of example 3 are generally better than the rats in the model group. The comparative example 1 group was observed to be inferior to the non-example 3 group.
(2) The influence on the body quality, liver index and serum AST and ALT levels of rats with acute alcoholic liver injury is shown in Table 5.
TABLE 5 Effect on body quality, liver index and serum AST and ALT levels in rats with acute alcoholic liver injury
Note: p <0.01, P <0.05 was compared to model groups.
And (4) test conclusion: the tests show that the composition has good protective effect on liver injury, can obviously improve weight, appetite, activity and the like, and test data show that the composition has extremely lower liver injury than a model group, and the protective effect on liver injury is reduced after the dosage of hydrolyzed whey protein is reduced and arginine is removed, so that the composition is an organic whole.
