What Are the Different Types of Synthetic Bone Graft?

Bone marrow transplantation (BMT) is the treatment of transplanting normal bone marrow cells from donors by intravenous injection to patients with hematological difficulties such as leukemia or aplastic anemia. In addition to bone marrow, hematopoietic stem cells used in bone marrow transplantation can also be obtained by recovering PBSCT or umbilical cord blood from peripheral blood. It is collectively called hematopoietic stem cell transplantation.

Transplant bone marrow

Bone marrow is present in

1. Timing of BMT: The efficacy of BMT in the first remission period is better than that in the second remission period. Brotint et al. (1988) compared the results of the first remission period and the second remission period of BMT in AL patients, and found that the 5-year relapse rate after the first remission period was 21% ± 11%, and the 5-year disease-free survival rate was 46% ± At 9%, the 5-year relapse rate and survival rate of patients after the second remission BMT were 56% and 22%, respectively. IBMTR and Seattle data have similar results. therefore,

Disease alias:

Infections are caused by blood-borne microorganisms (

Myelodysplastic syndrome (MDS) is a group of hematopoietic myeloids

Generally clinically

It is generally believed that the essence of MDS is a disease in which hematopoietic cells gradually change from normal to interstitial, and then transform into leukemia, accompanied by morphological changes (morbid hematopoietic) and abnormal hematopoietic function (ineffective hematopoietic), that is, benign, anaplastic and malignant Hematopoietic clones coexist in MDS. A series of problems such as etiology, pathogenesis, turning to white, and diagnosis and treatment are all difficult points.

Difficult point one: diagnosis of MDS

Due to the complexity of clinical manifestations (such as the possibility of pathological hematopoiesis), the limitations of morphological techniques, the lack of correctness of the clinician's understanding of MDS, misdiagnosis of clinical MDS, and missed diagnosis are not uncommon. This is a difficult problem that needs to be solved urgently. To this end, efforts should be strengthened in the following areas.

1.Ensure the reliability of MDS diagnosis.

2. Pay attention to differential diagnosis. The exclusion diagnosis of MDS should include the examination of hemolytic anemia, aplastic malignant tumor, liver disease, kidney disease, immune system disease and tuberculosis.

Difficult point two: There is no effective treatment for MDS

How to reduce or delay the conversion of MDS patients to acute leukemia is a major difficulty in treatment. Different treatment strategies for different types of MDS

MDS has three types of transfer regulations; the key to improvement, lingering, deterioration, and transfer regulations is whether to adhere to reasonable and scientific treatment. Physical strength, prosperity of the spleen and kidney, and regulation of liver qi. Therefore, for the treatment of various types of MDS, comprehensive or integrated Chinese and Western medicine measures should be adopted, including: Western medicine to stimulate bone marrow hematopoietic (RA, RAS), induced differentiation (RA, RAA, RAEB), low-dose chemotherapy (RAEB), combined Chemotherapy (RAEB-T), syndrome differentiation and treatment of TCM, diet conditioning, life conditioning, and mental conditioning, through comprehensive treatment of traditional Chinese and Western medicine, with a view to suppressing bone marrow pathological hematopoiesis, improving the body's immune function, thereby improving MDS, reducing or delaying deterioration.

[Rehabilitation guidance]

1. Pay attention to the nutrition and reasonably prepare the diet. The intake of meat, eggs and fresh vegetables should be comprehensive, and not partial.

2, taboo, chicken is Yang, moving wind. MDS is mixed with false and real. Particular attention should be paid to those with yin deficiency, fire, bleeding, and phlegm dampness.

3, Cordyceps sinensis stewed duck Cordyceps sinensis 5g, duck 75g, 3 slices of ginger, rice wine 5g, 200ml water, season with salt and oil, simmer for 2 hours, drink soup and meat. Treatment of MDS deficiency of qi and yin, fatigue, red tongue, thin pulse.

4. The mental conditioning of liver-qi stagnation is closely related to the onset of MDS. Some data suggest that there is more severe mental stimulation for more than half a year before the onset of MDS. Therefore, it is very important to promote imagination, open-mindedness, and improve self-cultivation. It is very important in the process of disease modulation .
