Description

technical field [0001] The invention relates to the field of medicines, in particular to the use of ginkgolides in the preparation of medicines for preventing and / or treating polycythemia vera. Background technique [0002] Polycythemia vera (PV) is a hematopoietic stem cell clonal disease of unknown cause, which belongs to the category of myeloproliferative diseases. According to relevant literature reports, the incidence rate of the disease is 1.9 / 100,000 to 2.6 / 100,000, and the incidence is mostly among middle-aged and elderly people, among which the most common age group is 50-60 years old, and the incidence rate of women is slightly lower than that of men. Clinically, it is characterized by a significant increase in the number and volume of red blood cells, with manifestations caused by plethora and hyperviscosity, often accompanied by splenomegaly. The onset of PV is insidious, the progression is slow, and various transformations may occur in the late stage. [0003]...
