Abstract

The invention discloses a feed for constructing a nonalcoholic steatohepatitis model of nonhuman primates and an application method of the feed. The feed comprises the following raw materials in partsby weight of 22-28% of soybean meal, 2.5-3.5% of Peru fish meal, 2-3% of feed-grade calcium hydrogen phosphate, 0.2-0.4% of salt, 0.1-0.3% of composite multiplex vitamins, 0.1-0.3% of high-stabilityVC, 0.4-0.6% of cholesterol, 20-25% of monocrystal levulose, 15-20% of animal oil and fat, 0.2-0.4% of methionine, 1-2% of premix minerals, and 30-35% of first-grade flour. A nonalcoholic steatohepatitis disease scoring system standard is used, and various individual index scores in a fibrosis scoring standard are obviously increased. After the feed is used for feeding the nonhuman primates for 3months, nonalcoholic steatohepatitis liver injury can be established, so that the nonalcoholic steatohepatitis animal model is formed.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a feed for constructing a non-alcoholic steatohepatitis model of non-human primates and a use method thereof. Background technique [0002] As a country with a high incidence of liver disease in China, patients with liver disease have caused serious economic and social burdens to the country and society. Data show that in 2016, the overall scale of drugs for liver diseases in my country exceeded 50 billion yuan. Nonalcoholic steatohepatitis (NASH, nonalcoholic steatohepatitis) is an extreme form of nonalcoholic fatty liver, defined as the appearance of steatosis accompanied by inflammation and liver cell damage. NASH can lead to advanced liver fibrosis, cirrhosis, liver failure and the development of liver tumors. In the past 20 years, the incidence of NAFLD has doubled and is now the most common liver disease in China and Western countries. At present, there is no drug to...
