Thrombocytopenia of 80 is generally defined as a decrease in platelets of 80×10^9/L, which is mainly due to the obstacle of production, increased consumption and abnormal distribution of platelets, and there is the possibility of aplastic anemia, primary immune thrombocytopenia and myelodysplastic syndromes and other diseases. Patients can be treated with medication and general measures according to different causes as prescribed by the doctor. 1. Aplastic anemia: Aplastic anemia may lead to thrombocytopenia. Patients can be treated with allogeneic hematopoietic stem cell transplantation as prescribed by the doctor, as well as androgens and immunosuppressive drugs such as prednisolone tablets and cyclosporine. 2. Primary immune thrombocytopenia: also known as idiopathic thrombocytopenic purpura, chronic patients with platelet counts often in (30~80) × 10^9 / L. Patients need bed rest, to prevent trauma, can be applied to glucocorticosteroids such as methylprednisolone, hydrocortisone and other roles of the first choice for treatment of drugs. 3. Myelodysplastic syndromes: patients with myelodysplastic syndromes usually show persistent reduction of whole blood cells and platelet count <100×10^9/L. For patients with severe anemia and bleeding, they can choose to have transfusion of component blood for symptomatic treatment. Patients with myelodysplastic syndromes can be treated with drugs such as decitabine or hematopoietic stem cell transplantation. When the thrombocytopenia is 80×10^9/L, it is recommended that the patient go to the regular hospital in time for further examination to find out the cause of the disease, and according to the cause of the corresponding treatment. Drugs should be used under the guidance of a doctor, avoid self-medication.
