　　Syndrome of deficiency of QI is caused by chronic illness, old age and infirmity, eating disorders, and improper medication.

　　[Modeling mechanism] Based on the theory of qi and blood, rabbit bloodletting is used to build a qi deficiency model; if there is a basis for labor, qi will be consumed, and the animal will be overworked to make a qi deficiency model; if there is an irregular diet, it can cause qi deficiency, use control mouse feed Method to get the Qi-deficiency model.

　　[Modeling method] Rats can be swim in a constant temperature water tank with a water temperature of (43±0.5)℃ and a water depth of 35cm using the method of overwork. The time for each rat to settle naturally is the swimming endurance time. When the whole group When 50% of the rats had spontaneous subsidence, all of them stopped swimming, and recorded their symptoms and signs for 14 consecutive days, and measured the relevant indicators.

　　[Model Features] The modeled rats appear to be curled up in groups, bunched, arched, mentally tired, addicted to lying, lazy, weak limbs, slow to respond, and at the same time, they have haggard or even sparse hair and are obviously thin.

　　[Model Evaluation and Application] This model is easy to establish, and the measurement indicators are objective and reliable, but care must be taken to keep the temperature constant. It is mainly used for research on essence of Qi deficiency and screening of Qi deficiency drugs.
