Dr. Liu graduated from the Department of Biochemistry, Nanjing University, in Detroit and Chicago were given medical doctorate and accept residency training. She was in the United States National Institutes of Health Cancer Institute (National Institutes of Health, National Cancer Institute) to accept the tumor and blood specialist training is currently the tumor blood disease specialists, and now practicing Sugar City.
Dr. Liu said that the blood tumor is a blood disease, also known as leukemia, adults and children are bound to happen, that is leukemia. Many different types of leukemia, the causes of abnormal lesions in the blood, and the emergence of blood in the bone marrow, which have different types and functions, the source of bone marrow stem cells.
When the stem cells into the lymphatic system and the hematopoietic system, hematopoietic system on the manufacturing leukocyte (white blood cell), red blood cell (RBC) and platelets. Interleukin as the body's defense, red blood cells to carry oxygen, platelets are responsible for blood coagulation. Leukemia can occur in any of these stages of differentiation, the more stem cells close to the more serious condition, the farther away from the stem cells of the disease on the development of more slowly. So there are acute and chronic leukemia are acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) for only a few months of life, chronic lymphatic leukemia (CLL) life is 3-10 years, chronic myeloid leukemia ( CML) lives a comparatively short period, from 3 to 5 years.
Cells in bone marrow diseases can not be used to check the number of blood cells to decide, we must depend on the shape of cells, the shape is not normal, is unable to control the growth of cancer cells in blood diseases. When the number of excess fill the bone marrow, the healthy lymphocytes, granulocyte and white, and red blood cells and platelets have been on the exclusion, no, too much lesion cells, with the outflow of blood bone marrow, the body throughout the movement and came to a standstill For example, liver, heart, kidneys, where growth.
As the red, white blood cells and platelets and the disappearance of a significant reduction, so the development of leukemia is the inflammation, can not stop bleeding, organ failure and death. Exchange transfusion and physical mutilation are not used, because lesions in the bone marrow inside, not to enter the bone marrow will not be able to cure.
Cancer of the blood of the pathogenic factors are: 1, high radiation: the Marie Curie discovered radium died of leukemia is found that the principle of X-ray photography of Rosalind Franklin died of uterine cancer. 2, chemotherapy and died of excessive lead to leukemia. 3, long-term exposure to the chemical benzene, 4, suffering from Down's syndrome, 5, virus infection. And preventive measures, up to now still do not know how to prevent. But know that if there are changes in cell chromosomes, his condition will develop very quickly.
Dr. Liu said that in the treatment of early stage can be used for drug treatment and chemotherapy, new drugs can be the molecular formula of special medication, less toxic and more effective. If the broken bone marrow transplant will have to come out. The past is a bone marrow transplant, usually with brothers and sisters of patients with bone marrow stem cells extracted from them, and now as long as collected from the peripheral blood stem cells will do. And then the bone marrow of leukemia patients to kill all the cancer cells, and then a healthy stem cells into bone marrow, using drugs to help its growth.
