Problems solved by technology

There are only reports of some scholars using simple high-fat diet and exhaustive swimming to create obese animal models. The method is to use high-fat diet and exhaustive swimming to damage the spleen and stomach, create internal dampness, and cause animals to suffer from poor appetite, less drinking, weight loss, This type of model still has the following obvious deficiencies: First, the repeatability and stability of the model manufacturing method is poor, there is a lack of uniform modeling standards, there are too many uncontrollable factors, and the objectivity and standardization are poor
Second, the formation of spleen deficiency is a long-term and chronic process. The syndrome of spleen deficiency cannot be formed in such a short period of time. It may only be a short-term state, which is easy to recover naturally, and there is a big gap with the syndrome of traditional Chinese medicine.
Third, traditional Chinese medicine believes that the body has symptoms such as drowsiness, fatigue, and listlessness as dampness, so it is often difficult to judge dampness in experimental rats.
The above-mentioned model of spleen deficiency and damp resistance mainly uses general conditions such as body weight and blood lipid indicators as evaluation indicators, which is not specific and difficult to be objective
Fourth, there is a gap with clinical

Embodiment 1

[0032] Embodiment 1: The construction of the rat model of obesity disorder for female obesity research

[0033] (1) Experimental animals: 100 SPF grade female SD rats, 6 weeks old, weighing 180±20g, provided by Hunan Slake Jingda Experimental Animal Co., Ltd., experimental animal license number: SCXK (Xiang) 2016-0002. Animal breeding conditions: According to the circadian rhythm of natural lighting, they were raised in an SPF-level experimental animal barrier system, and the license number for the use of experimental animals was SCXK (Gan) 2017-0004. The laboratory temperature is 23±2°C, and the relative humidity is 53±3%. The animals were given free access to water and food, and the experiment was carried out after three days of adaptive feeding.

[0034] (2) Feed:

[0035] The ingredients of normal basic maintenance feed (full price nutritional feed) are: Choline Chloride 0.2%, Corn 30%, Wheat 25.5%, Molasses Yeast 2.5%, Calcium Hydrogen Phosphate 2%, Stone Powder 1%, Gro...

Embodiment 2

[0045] Embodiment 2: three-dimensional syndrome differentiation of obesity model

[0046] (1) According to the following indicators, for the obesity rat model of female obesity research established in Example 1, from the three-dimensional evaluation and statistical analysis of the obesity rat model, the syndrome types for female obesity research are distinguished. Among them, the first dimension is to look for the general condition indicators of rats to evaluate the model mice according to the four diagnostic performances of human diseases; the second dimension is the water and salt load test; the third dimension is the hematological indicators.

[0047] The first dimension is to evaluate the model mice, specifically:

[0048] Mental behavior is divided into 0-3 grades: rapid activity and bright eyes are grade 0; mild abnormalities (sluggishness, decreased spontaneous activity) are grade 1; moderate abnormalities (mental burnout) are grade 2, and obvious abnormalities (abdomin...

Abstract

The invention relates to the technical field of biomedicine, and specifically discloses a method for constructing an animal model for female obesity research and its application. The animal model construction method comprises the following steps: select female adult rats for use; feed with high-fat, high-protein, high-sugar feed; carry out forced weight-bearing swimming, continue 21 days from the 8th day of feeding with high-fat, high-protein feed, and be fed every day Swim with a forced load for 3 minutes; while swimming with a forced load, they were given ice water for 21 days; after that, they were simply given a sufficient amount of high-fat, high-protein, and high-sugar feed. After a total of 60 days of modeling, if the weight, body length and Lee's If the index is significantly different from the normal control, the modeling is completed. The invention solves the deficiency of disease animal models and evaluation of obesity model syndrome types that are not currently used for female obesity research, and provides a new model for standard, standard and scientific evaluation of weight loss and fat reduction traditional Chinese medicine research. It has the characteristics of simple modeling method, easy operation and popularization, close to clinic and so on.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for constructing an animal model for female obesity research and its application. Background technique [0002] Traditional Chinese medicine believes that the internal injuries of the seven emotions cause dysfunction in the spleen, stomach, and liver in the human body, and excess fat cannot be converted into heat and excreted, and it is deposited in the body to cause obesity. Specifically, whether the metabolism of water in the body is normal or not is closely related to obesity. The spleen governs movement and transformation, and the stomach governs acceptance. Improper diet the day after tomorrow will damage the spleen and stomach, just as the "Su Wen Interpretation" says: "Eating fat will stagnate the Qi and not reach it, so the internal heat; eating sweet will slow down the Qi in the middle and retain it well, so Zhongman". Therefore, insufficient temper or...
