On March 4th, between two flower beds in quancheng square, Jinan, Qiqi, a 7-year-old girl, gritted her teeth and ran round and round. When I was tired, I squatted down panting, then continued to stand up and run, clutching two small fists. Running all morning, one day 10 km, she has been indifferent to sports for a whole week. ? Because I want to save my sister! ? In June last year, Kiki's sister Xiaohan was diagnosed with severe aplastic anemia. The best treatment is bone marrow transplantation. After matching, Kiki is the most suitable candidate. ? The better my health, the greater my sister's hope of treatment. I want to exercise myself more! ? Kiki looked at the front and ran hard, and every step carried the hope of the whole family. Every time after running, Kiki's mother often takes her daughter home and lets her fall asleep on her shoulder. She tried her best to comfort her daughter and make up for her guilt.
Weight increased to 50 Jin. ? This is the task that the doctor gave Kiki. From this goal, there is still a distance of 8 pounds. Kiki gritted her teeth and insisted on running every day to exercise herself. A pack of 2.50 yuan snacks and a glass of water, all when mom ran to find Kiki? Supply? . Simple clothes and a pair of sneakers with glue are all her running equipment. ? I now eat steamed bread and pickles every day and save some money to satisfy my children as much as possible. ? Yu Yan said.
Then why do we see in the news every year that minors donate bone marrow to save their loved ones and ask donors to gain weight quickly within a period of time? Is it necessary? First of all, it must be clear that donating peripheral hematopoietic stem cells and blood donation have almost the same impact on the human body. Usually, when we estimate a person's safe blood collection, we usually take weight as the standard. The total amount of human blood accounts for about 8% of body weight. For example, a person weighing 50 kilograms has a total blood volume of about 4000 ml. The blood loss at one time does not exceed 15% of the total blood volume in the body, which basically does not affect the normal physiological function and is a relatively safe range. If the blood donors are relatively small (such as minors), then the total amount of blood is relatively small, and the same amount of blood collection will have a relatively greater impact on them, which may be the reason why doctors suggest that the weight should reach a certain standard. Why did you run? Because it is necessary to improve the immunity and physique of the donor.
Let me remind you again that running is simple, but it is also very professional. For children, even if it is above 1KM, it will take some time to undertake and complete the training. Parents of runners who want to take their babies to run must do what they can, and they must not be forced at will!
