In 2017, cord blood, an important source of hematopoietic stem cells, has its own festival: "World Cord Blood Day", which is held on November 15 each year. The creation of this festival also hopes that the public will realize the value of cord blood!
On the evening of November 15th this year, the light show in Hangzhou Qianjiang New Town will call for cord blood and World Cord Blood Day, calling on the public to pay attention to cord blood and cherish it. This precious resource of life!
What is umbilical cord blood, why should we keep cord blood
Cord blood is blood collected from the umbilical vein after the fetus is delivered and the umbilical cord is broken. It is rich in hematopoietic stem cells and is one of the three major sources of hematopoietic stem cells. One (the other two are bone marrow and peripheral blood). The collection of cord blood has no effect on mothers and babies.
In 1988, the world's first umbilical cord blood transplantation case was successfully completed in France. Today, the former child Matt Farrow has grown up, married and had children, and has a good quality of life after surgery. This is the beginning of the treatment of patients with cord blood worldwide.
Cord blood is a valuable life resource. After more than 30 years of research and application, it not only plays an important role in the treatment of blood diseases and immune system diseases, but also explores neurological diseases such as cerebral palsy, cardiovascular and cerebrovascular diseases, and diabetes. And other fields have also made great contributions. According to the staff of the Zhejiang cord blood bank, as of now, the amount of cord blood stored in the cord blood bank in Zhejiang has exceeded 100,000. The cumulative number of cord blood applications out of the bank is 472, and the number of rescued patients has reached 460, treating diseases The top five are acute myeloid leukemia, acute lymphoblastic leukemia, aplastic anemia, myelodysplastic syndrome, and lymphoma; in these more than 400 applications, the oldest patient is 71 years old, and the patient with the greatest weight is 100kg . Compared with other sources of hematopoietic stem cells, what are the advantages of cord blood? Compared with other sources of hematopoietic stem cells,
has some unique advantages. For example, cord blood will not cause any risk to the donor; at the same time, the physical preservation of cord blood can provide more timely transplant opportunities, and there is no need to worry about the temporary remorse of the hematopoietic stem cell donor before the transplant.
In addition, cord blood transplantation has the advantages of low recurrence rate, low rejection rate and light degree after transplantation and low matching requirements.
About umbilical cord blood How should we treat
scientifically? Because of the short history of cord blood application, people do not have enough knowledge about cord blood, so naturally they will have some common doubts and even misunderstandings about cord blood. Taking advantage of the approaching World Cord Blood Day, I would like to clarify your doubts as follows:
1, does the collection of cord blood affect mothers and babies?
Regarding this question, the head nurse, Sun Min, Department of Obstetrics and Gynecology, Peking University People’s Hospital has made an authoritative opinion. Explanation. She said that the collection of umbilical cord blood must be collected after the fetus is delivered and the umbilical cord is broken. There is no situation in which infant blood is collected, and it is safe for both the baby and the mother.
2. Is the collection, preparation, testing and storage of cord blood trustworthy?
The National Health Commission conducts unannounced inspections on seven legally established cord blood banks across the country (Beijing, Tianjin, Shandong, Shanghai, Zhejiang, Sichuan, Guangdong) every year , Every three years, a comprehensive re-practice acceptance inspection will be carried out on each process of the cord blood bank. Therefore, the storage of cord blood in these seven legally established cord blood banks is trustworthy.
3. Can umbilical cord blood only be used for small-weight patients?
Professor Sun Zimin, deputy dean of the First Affiliated Hospital of the University of Science and Technology of China and an expert on cord blood stem cell transplantation, said based on the cord blood transplantation cases he completed: "Since 2003 , We use a single cord blood transplantation to treat adult hematological malignancies in 60 or 70 cases every year, and there are already many successful cases. We now have the largest weight of a single cord blood (cord blood transplant) can reach 80 kg Or 90 kg patients, the implantation rate of cord blood can be as high as 97%."
4, can self-storage cord blood not be used on oneself?
Beijing Jingdu Children’s Hospital Vice President Professor Sun Yuan pointed out: Autologous cord blood transplantation has Very big advantage, because autologous cord blood transplantation does not have the problem of transplant rejection, so there will be no transplant failure. In addition, autologous cord blood has different requirements for the number of cells than allogeneic cord blood. In principle, a small number of cells can meet the transplantation standards, which can guarantee the transplantation.
So far, there have been more than 18,000 umbilical cord blood application cases in my country, which once again proves its great value in the field of disease treatment. I believe that in the future, cord blood will have a broader application prospect.
