Polycythemia vera (hereinafter referred to as PV) is a bone marrow hematopoietic stem cell abnormalities caused by myeloproliferative diseases. It is characterized by erythrocytes, blood volume was significantly increased, accompanied by increased neutrophils and platelets, the incidence of slow, longer duration, often with advanced bone marrow fibrosis and extramedullary hematopoiesis. The disease is relatively rare, true red blood cell research group (hereinafter referred to as PVSG) since its establishment in 1967, has accumulated more than 1,000 cases of myeloproliferative diseases, established the diagnostic criteria of PV and other diseases, and
