Zhou Yunbo, a 27-year-old soldier of a group army, joined the army in Chongqing at 201/. After nine years of military training, he has developed a good character of courage, perseverance, unity and mutual assistance. By chance, he completed the volunteer registration of Chinese Bone Marrow Bank in Sichuan Red Cross Society and took 10 ml blood sample for storage. In April this year, Zhou Yunbo received a notice from China Bone Marrow Bank that a female leukemia college student in Qingdao, Shandong Province had successfully matched her hematopoietic stem cells.
Before donating hematopoietic stem cells, the patient's mother wrote a sincere thank-you letter to Zhou Yunbo. Zhou Yunbo was also very moved after reading it. He asked his wife to write back, encouraging and wishing the sick girl an early victory. On July 30th, Zhou Yunbo extracted hematopoietic stem cells from the Hematology Department of Sichuan Provincial People's Hospital. 222 ml of hematopoietic stem cell suspension was isolated from Zhou Yunbo's body, and then transported to Qingdao by special car, which could be input into the patient's body that night to complete the transplantation.
It is understood that donating hematopoietic stem cells has little impact on the human body. The only trauma is that the blood collection site is easy to form scars, and human blood can return to its original level within 1-2 weeks. Donating hematopoietic stem cells now does not need to directly extract bone marrow, but directly extract peripheral blood, which is equivalent to donating blood and will not affect people's health. Bone marrow stem cells are of great significance to human body, which can differentiate into white blood cells and red blood cells, and play a protective and immune role in human body. After donation, people may feel tired in a short time, and their immunity will decline. After a period of rest, they will gradually improve.
