Myelodysplastic syndrome is a disease in which the hematopoietic function is seriously disrupted. Bone marrow is a hematopoietic organ of the human body, just like a big factory producing various necessities of life. If the bone marrow proliferation is abnormal, it is like using a lot of raw materials for production, and the things produced are all defective and cannot leave the factory. With reduced normal blood cells and abnormal blood cell function in the body, there will be anemia symptoms such as weakness, shortness of breath, panic and chest tightness; with reduced granulocytes, there will be poor resistance and repeated infections. With reduced platelets and abnormal function, petechiae and petechiae, gum or nasal bleeding may occur when there is no touching or bumping. Some people may also show signs and symptoms such as loss of appetite, night sweats, fever or splenomegaly. Diagnosis 1.Blood count: The most direct way to check the number and type of cells in the peripheral blood. 2.Bone marrow aspiration: to observe the number, type and morphology of bone marrow cells with a microscope. 3.Chromosome: This test is not only needed for typing, but also helpful in assessing disease progression. MDS does carry a risk of turning into leukemia. Western medical treatment can be divided into several parts: 1. supportive treatment, that is, blood transfusion, platelet transfusion, anti-infection in case of infection, iron drainage, etc.; 2. low-intensity treatment, injection of red blood cells, platelet granulocyte growth factor, immunosuppressive therapy; 3. chemotherapy; 4. bone marrow transplantation.
