　　Objective: To establish a peripheral blood thrombocytopenia model consistent with the "Heatchen syndrome" of traditional Chinese medicine and primary immune thrombocytopenic purpura.

　　Methods: Multiple injections of 20% dry yeast suspension into the back of SD rats, intraperitoneal injection of 1:4 dilution of rabbit anti-SD rat platelet serum (APS), primary immune thrombocytopenic purpura to establish a rat disease fever model . Then, observe the TCM syndrome characteristics, blood image, bone marrow image and 5-hydroxytryptamine (5-HT) level of the temperature regulation center of the thalamus of the tested rats.

　　Result: 2-6 hours after injection, the body temperature and daily water consumption of rats in the model group increased significantly. Purpura on the toes appeared on the 4th day of the model, and intestinal mucosal hemorrhage appeared on the 30th day of the model (P\u003c0.05); (P\u003c0.05); The 5-HT level in the temperature control center was obvious in the brain Increase (P\u003c0.05).

　　Conclusion: The rat model of primary immune thrombocytopenic purpura combined with diseases and syndromes is essentially the pathology of primary immune thrombocytopenic purpura caused by "purpura" rats "fever", reflecting its characteristics .
