This acquired platelet dysfunction may be no clinical symptoms or bleeding, thrombosis and other symptoms, and participate in the occurrence and development of abnormal pathology such as diabetes, so in the primary disease to grasp the changes in platelet function, to improve its dysfunction, not only Prevention of concurrent bleeding and thrombosis, and can prevent the progression of the primary disease. This article reports 32 cases of polycythemia vera (PV), 13 cases of essential thrombocythemia
