Bone marrow transplantation can be divided into autologous bone marrow transplantation and allogeneic hematopoietic stem cell transplantation according to the source of hematopoietic stem cells. Autologous bone marrow transplantation is a process of taking out hematopoietic stem cells from patients in advance and freezing them in liquid nitrogen. After pretreatment, the user quickly dissolves the frozen hematopoietic stem cells and then infuses them into the user. This is autologous hematopoietic stem cell transplantation.

In allogeneic hematopoietic stem cell transplantation, the peripheral blood of the user should be drawn in advance, and then the appropriate matching should be found in the bone marrow bank. If there is a complete bone marrow match, the user goes through a pretreatment scheme, and then takes out the donor's hematopoietic stem cells and returns them to the user's body, so that other people's hematopoietic stem cells can rebuild hematopoiesis in the user's body. This is allogeneic hematopoietic stem cell transplantation.

Precautions:

1. After transplantation, users not only have low immunity, but also have slight atrophy of lower limb muscles in most cases. Therefore, we should increase the activity step by step indoors and then outdoors to restore physical strength and enhance resistance. Adjust your mentality and keep a relaxed and happy mood. Ensuring adequate sleep is particularly important for patients.

2. Review on time: In order to know the condition in time and be aware of it, users should regularly go to the hospital to review blood routine and biochemical indicators according to the doctor's advice. If you have any discomfort (such as rash, cold, fever, diarrhea), you must go to the transplant hospital in time and be treated under the guidance of a doctor. After the condition is stable, you can go to other hospitals for regular review. Six months, one year and two years after transplantation, go back to the transplant hospital for a comprehensive review and listen to the doctor's advice.

3. Nutritional supplement: users consume a lot of energy in the process of accepting hematopoietic stem cell transplantation. Most users will suffer from malnutrition and physical decline to some extent, so they must be supplemented with proper nutrition. Attention should be paid to a diet with high calorie, high protein and high vitamins, mainly light semi-liquid or pasta. You can eat more digestible foods such as sparerib soup, chicken soup and fish soup, and then add vegetables and fruits.
