Embodiment 1

[0017] Example 1 Preparation of the animal model of the present invention

[0018] 1. Experimental animals: SPF male AopE- / - mice, 6-8 weeks old, body weight (22±2) g, purchased from Changzhou Cavens Laboratory Animal Co., Ltd., Jiangsu Province [SCXK (苏)2011-003 ]. SPF male C57BL / 6 mice, 6 to 8 weeks old, body weight (22±2) g, purchased from Beijing Weitong Lihua Laboratory Animal Technology Co., Ltd. [SCXK (Beijing) 2011-0011].

[0019] 2. The experimental animals are kept in the barrier environment of this department, the temperature is 22~25℃, the humidity is 50%, and the day and night alternate for 12 hours.

[0020] 3. After 1 week of adaptive feeding, the experimental animals were randomly divided into four groups, each with 8 animals. The detailed grouping situation is shown in Table 1. The model was built for 10 weeks with a fixed dose of feed in the morning and evening, guaranteed 40g / cage, 4 mice per cage, free water during the period, the water source was SPF sterilized...

Abstract

The invention relates to the establishment of an animal model of non-alcoholic fatty liver disease, in particular to the establishment of a non-alcoholic fatty liver animal model induced by high fat accompanied by severe blood fat abnormality. SPF-grade male AopE- / - mice and C57BL / 6 mice were selected, randomly divided into model group and control group according to the species of mice, a total of 4 groups, 8 mice in each group, and all mice were adaptively fed with ordinary maintenance feed for 1 week. , the model group was given high-fat feed, and the control group was given control feed. After 10 weeks, the blood was drawn and sacrificed, and the four items of routine blood lipids and liver function were tested; Liver tissue was made into paraffin and frozen sections, and H.E. and oil red O staining were performed respectively to determine the effect and quality of the NAFLD model. The present invention uses a simple high-fat and high-calorie diet to make models, and creates a severe NAFLD model within a very short period of 10 weeks. The model's blood lipids, liver fat and other indicators have excellent stability and high repeatability, which is a high-quality NAFLD model. Establishment provides a reliable method.

Description

Technical field [0001] The present invention relates to the establishment of a non-alcoholic fatty liver disease (NAFLD) animal model, in particular to the establishment of a type of high-fat-induced non-alcoholic fatty liver animal model with severe dyslipidemia. Background technique [0002] Non-alcoholic fatty liver disease (NAFLD) refers to a clinical pathological syndrome characterized by excessive deposition of fat in liver cells in addition to alcohol and other clear liver damage factors. NAFLD is composed of a series of continuously developing diseases. Only simple fatty liver (SFL) and non-alcoholic steatohepatitis (NASH) occur in the early stage. With the development of the disease, fibrosis of the liver tissue will eventually be triggered and lead to the formation of liver cirrhosis. At the same time, obesity and dyslipidemia caused by NAFLD are also the culprits for other metabolic disorders, such as atherosclerosis (AS), hypertension and type 2 diabetes. With the p...
