Recently, a patient in Wenzhou, Zhejiang Province who had a Bombay-like blood type called "dinosaur blood" was in urgent need of blood transfusion during surgery. The probability of this blood type appearing is only one in hundreds of thousands. The Wenzhou Central Blood Station actively responded to the demand for blood and promptly thawed the frozen blood for clinical use to solve the patient's urgent need.
Today (June 14) is the 20th "World Blood Donor Day". The topic of "dinosaur blood" quickly topped the list of hot searches across the country, and it also focused people's attention on the field of blood donation.
The timely treatment of patients with the "dinosaur blood" blood type seems to be an accident. Behind the scenes, Zhejiang has already established a thorough protection mechanism for patients with rare blood types, and supports the huge daily blood demand and provides blood with rare blood types. It is the arms extended time and again by many blood donors. There are 2,300 brave people in Zhejiang every day passing on their love and energy in this way. 59-year-old Bao Weiming is the person who has donated blood the most in Zhejiang Province, with a total of 396 blood donations in 24 consecutive years.
"I obviously feel that the number of blood donations has been gradually increasing in recent years, and young people have accepted it at a high rate, especially college students. Zhejiang provides many preferential policies for blood donors, such as being the first in the country to introduce free subway and bus rides , going to the park for free, seeing a doctor without registration fees, etc., and working with blood donors in both directions,” Jin Yi, leader of the Zhejiang Provincial Hematopoietic Stem Cell Donation Volunteer Service Team, told reporters on June 14.
Blood of rare blood types can be stored frozen for up to ten years
According to reports, the timely blood transfusion of this "dinosaur blood" patient in Wenzhou is the first time that blood of this blood type has been used clinically in Zhejiang. After receiving the clinical demand, the Wenzhou Central Blood Station found the bag of "dinosaur blood" from the blood storage refrigerator below -65°C. After a series of preparation processes such as thawing, washing, and removing glycerol, the bag of blood was sent to clinical patients. use.
In my country, there are only nearly a hundred reports of Bombay type and Bombay-like blood types. Bombay-like blood type is extremely rare among the Chinese population. In May 2023, Shenzhen People's Hospital accidentally discovered a 64-year-old patient with "dinosaur blood" during a consultation. The Blood Transfusion Department of Shenzhen People's Hospital started a difficult identification process and finally determined that his rare blood type was "Bombay-like type".
"Among the Han population, the probability of rh-negative 'panda blood' existing is about three thousandths, while the probability of existence of 'dinosaur blood' like 'Bombay-like blood type' is one hundred thousandths, and Even rarer, there is the 'p blood type' and 'k negative blood type' with a probability of one in a million. Ensure the scientific and rational use of rare blood type blood and the scientific and rational use of blood to avoid "no one donates it when it is urgently needed, and no one uses it when it is donated." "In this case, the center has established a thorough guarantee mechanism for rare blood types." Hu Wei, director of the Zhejiang Provincial Blood Center, said that for example, the Zhejiang Provincial Blood Center has established a "triple protection mechanism" around the well-known rare blood type - rh-negative "panda blood". Safety precautions. The first level of protection is to maintain 10 units of rh-negative liquid blood every day (1 unit is 200 ml) to ensure that blood can be produced immediately in an emergency; the second level of protection is to place frozen red blood cells of rare blood types in The freezing library at minus 65 degrees Celsius can be stored for 10 years. After thawing, it can be used for clinical emergency blood and emergency blood supply for emergencies. The thawing time is about 4 hours; the third level of protection is the establishment of a team with rare blood types - - "Panda Man" team, emergency recruitment for clinical blood supply.
At the same time, the Zhejiang Provincial Blood Center has established a provincial rare blood type information query platform to provide timely rare blood type blood query and clinical blood guarantee. Up to now, 8 types of rare blood types of red blood cells have been stored in the library, covering data of 7 blood group systems. There are nearly 300 blood donors of ultra-rare blood types, and more than 200 units of ultra-rare blood types are stored in the frozen storage. Once clinical needs arise, the ‘dinosaur blood’ in these frozen libraries can be used immediately. If necessary, emergency recruitment can also be carried out based on the name database. There are currently four people with Bombay-like blood types registered at the Wenzhou central blood station.
The person who has donated the most blood said bluntly: "It's still too late to donate blood"
"Now that I think about it, it's still too late for me to donate blood. If I had joined the blood donation team earlier, I could donate for a few more years." Bao Mingwei said bluntly. In September next year, he will turn 60, and according to regulations, he has reached the upper limit of blood donation age.
In 2000, Bao Mingwei, who was working in Jiaojiang, Taizhou, passed by Jiaojiang Cinema and saw a blood donation vehicle parked at the door. He took the initiative to donate blood for the first time in his life. "Not many people donated blood in that era because they were afraid that donating blood would be bad for their health. I just wanted to give it a try to see if donating blood would have any impact on my body." Bao Weiming's memory of his "first time" Very clear.
However, he did not feel any impact on his body, so he continued the "blood donation mode" for 24 years. I was still secretive at the time. Only my wife knew that I was donating blood. She neither supported nor opposed it. My parents didn’t know either. "Bao Weiming said.
Because he has to donate blood, he is very self-disciplined. He usually goes to bed around 10 p.m. and gets up at 4:30 in the morning. He often goes for a run for about an hour and a half. There are fitness equipment, barbells, dumbbells, etc. in the room. Just practice at home on a rainy day. "Blood donors are still running marathons. Does this mean that blood donation has no impact on the body and their quality is better than others? "He said with a smile.
Bao Weiming said that in fact, many people in Zhejiang Province donated blood earlier than him, but he persisted, and he donated blood components, so he could donate more often. Every time the time is up, he can After donating blood, he took the initiative to contact the local blood station to donate blood. Under his leadership, many people joined the team of blood donors.

This was his 324th blood donation. 52-year-old Fan Ligang has also been donating blood for 20 years, which coincides with the annual cycle of World Blood Donor Day.Speaking of blood donation, Fan Ligang remembered a scene from more than 20 years ago. It was the "double robbery" season in the summer. When he was inspecting the fields as a member of the team, he saw a farmer who was scratched by the propeller of a water pump and lost too much blood. "This incident is not good for me. I was deeply touched by how fragile life is. I want to do what I can to help more people in this life. "Fan Ligang said.
More than ten years ago, Fan Ligang learned that Hangzhou was in urgent need of blood, so he regularly took a bus from Shaoxing to Hangzhou to donate blood, and developed this habit. Not only that, he also became a blood donation volunteer, and his wife influenced him He decided to join the voluntary blood donation team.

Clinical blood supply is still in a "tight balance" state
Many people will have such doubts: Will voluntary blood donation and hematopoietic stem cell donation have any impact on the body in 2015? This is a way to tell everyone that donating blood and marrow has no impact on the body. Jin Yi has been donating blood for more than 30 years. In 1992, when he was a freshman, he signed up after hearing that the school organized a voluntary blood donation. There was no discomfort and he went back to school to play football. “After this experience, I wasn’t nervous at all. "
Jin Yi has observed that there are not many people participating in blood donation at social blood donation points. "I often meet a few people who come together, or they donate blood because their relatives or friends are sick and need blood. No one can guarantee that we, our relatives and friends will not get sick in our lives. We should do this when we are young and healthy. It can not only help others, but also be useful in case of illness and need. "

Data from the Zhejiang Provincial Blood Center shows that the total collection of voluntary blood donations in Zhejiang Province has also increased from 188.6 tons in 2013 to 266.8 tons in 2023, a year-on-year increase of 41.5%.In 2023, more than 830,000 people participated in blood donation in Zhejiang Province, and the blood donation rate per 1,000 people reached 12.64‰, ranking among the top in the country.
However, Hu Wei, director of the Zhejiang Provincial Blood Center, said that with the rapid development of medical technology, the demand for blood has also increased rapidly. At present, clinical blood supply is still in a state of "tight balance".
In fact, Zhejiang has been using various methods to encourage citizens to participate in blood donation. As early as 2001, Zhejiang promulgated the "Zhejiang Provincial Measures for the Implementation of the Blood Donation Law of the People's Republic of China", which were revised and implemented on January 1, 2014, further improving the protection and incentive measures for unpaid blood donation. For example, if you donate 400 ml of blood, you will be free for life. With blood, it was the first in the country to launch the "three exemptions" policy for award-winning blood donors.
In September 2018, the Zhejiang Provincial Blood Center and provincial hospitals in Hangzhou began to organize a pilot project of "blood donors give priority to blood use". Through the Internet system, provincial hospitals in Hangzhou report to the province's blood cloud platform through a private network every day. The ID number, name and other relevant information of hospitalized patients are compared with the province's blood donor name database to identify and feedback the status of blood donors. In August 2023, the project was promoted across the province, realizing data interconnection between cities-provincial hospitals-municipal hospitals and provincial blood centers.
"We have built 213 fixed blood donation points and 84 fixed blood donation houses across the province. Our goal is to have a blood donation house in every county or city by 2025, allowing everyone to donate blood conveniently at home." Zhejiang Hu Wei, director of the Provincial Blood Center, said.
“Twenty years of celebrating the gift of life: thank you, blood donors!” is the slogan for this year’s World Blood Donor Day campaign. The profound meaning of life and the endless transmission of energy have been best and infinitely explained in the drops of the most precious "little red crystals" in the world. (CCTV.com)
