1.Environmental protection therapy High-dose chemotherapy is a powerful measure for long-term survival or improving the efficacy of various tumor diseases, but the fever and serious infection brought by it make the chemotherapy dose obviously limited. Environmental protection therapy can provide a relatively sterile environment to avoid serious infection secondary to high-dose chemotherapy, so that tumor patients can safely pass the dangerous period after chemotherapy. Plasma exchange can effectively remove the abnormally increased blood lipids, abnormal antibodies and abnormal blood cell components from the body, and return you to a healthy body. Reduce the chance of blood-borne disease infection. 3.Hematopoietic stem cell transplantation For hematologic malignancies such as leukemia and lymphoma, hematopoietic stem cell transplantation has become a classical treatment modality. However, for tumors that cannot be cured by traditional radiotherapy treatment such as small cell lung cancer, breast cancer, cervical cancer, etc., it can provide a chance for complete cure, and also for hematopoietic stem cell transplantation for refractory autoimmune diseases such as systemic lupus erythematosus, multiple sclerosis, systemic sclerosis, rheumatoid arthritis, etc., it has become a treatment for complete cure. The Department of Hematology of Taihe Hospital has carried out autologous bone marrow transplantation, autologous peripheral blood stem cell transplantation, mixed bone marrow transplantation, donor lymphocyte infusion and other transplantation techniques to meet the needs of different patients. 4.Screening for thrombophilia With the improvement of living standard, the incidence of thrombophilia increases year by year, and thrombophilia becomes the patent of a considerable part of normal people, especially for various surgeries that seem to be normal before surgery but are very prone to thrombophilia after surgery, the Department of Hematology can provide preoperative and postoperative screening for thrombophilia to escort your surgery. 5.Therapeutic blood cell component mono-collection Blood cell components refer to red blood cells, white blood cells, platelets and hematopoietic cells in peripheral blood. Therapeutic blood component mono-collection mainly removes excessive pathological cells produced by various malignant proliferative diseases of the hematopoietic system, as well as secondary hematopoiesis, reduces the serious damaging effects of these cells on the body, and improves the clinical situation. This includes leukocyte (granulocyte, lymphocyte) removal, leukocyte removal in hyperleukocytic leukemia, therapeutic platelet monophoresis , therapeutic red blood cell monophoresis. 6. Peripheral blood stem/progenitor cell and lymphocyte harvesting Peripheral blood stem/progenitor cell transplantation (PBSCT) has been widely recognized as an alternative treatment for malignant diseases of the hematopoietic system and various solid tumors. Peripheral blood stem/progenitor cell collection is less invasive. Peripheral blood stem/progenitor cell collection, which requires processing of large amounts of extracorporeal circulating blood, is performed two to five times to obtain the necessary amount of hematopoietic stem/progenitor cells for hematopoietic stem cell transplantation after autologous and allogeneic peripheral blood stem/progenitor cell collection. Lymphocytes from peripheral blood are collected in the same way for donor lymphocyte infusion after allogeneic HSCT. 7.Bone marrow tissue biopsy pathological examination The new technology of plastic-embedded thin section, as well as the improvement of fixation and staining methods, enable the microscopic bone marrow tissue to be clearly layered, rich in color, and the morphology of hematopoietic cells to be clearly distinguished, which significantly improves its diagnostic and identification value compared with the original paraffin section. The morphology, distribution and localization of hematopoietic cells can be observed under the microscope, and non-hematopoietic cells, bone marrow stroma, bone trabeculae and endosteal cells can be observed. Bone marrow pathological histological examination is particularly important for the diagnosis of hematologic diseases, and has independent diagnostic value for some hematologic diseases, and complements cytomorphological examination of bone marrow smear to improve the diagnosis of hematologic diseases. 8.Bone marrow tissue print examination For hematological tumor diseases, bone marrow metastatic cancer or bone marrow puncture with dry aspiration, cytomorphological examination with bone marrow biopsy tissue print and cytochemical staining can greatly improve the diagnostic conformity rate of diseases. Bone marrow print is better than bone marrow smear in assessing the amount of nucleated cells, and a simple and rapid combination of print and smear can improve the diagnostic level of bone marrow cytology.
