Baby girl with cord blood saved 17-year-old boy after two years and 11 months
At 11:30 on November 24th, Luo Lili, a staff member of the Cord Blood Hematopoietic Stem Cell Bank in Sichuan Province, came to the Affiliated Hospital of North Sichuan Medical College and delivered a silk banner to Shi Qi, deputy director of the Department of Obstetrics and Gynecology, to all medical staff in the Department of Obstetrics and Gynecology. Express thankfulness.
A month ago, in the Xiangya Hospital of Central South University, a 17-year-old boy successfully received hematopoietic stem cell transplantation. Some of the hematopoietic stem cells in his body came from a man who was born in the Affiliated Hospital of North Sichuan Medical College in Nanchong two years ago. Umbilical cord blood of baby girl.
At 9:26 am on November 11, 2018, in the delivery room of the Affiliated Hospital of North Sichuan Medical College, a baby girl croaked on the ground.
The doctor skillfully cut the baby's umbilical cord, and quickly collected the blood remaining in the umbilical cord with a blood collection bag, and then sent it to the Sichuan Provincial Cord Blood Hematopoietic Stem Cell Bank in Chengdu.
After a series of strict tests and preparations, the cord blood was frozen in a deep cryogenic liquid nitrogen tank at -196°C.
It is understood that cord blood is rich in hematopoietic stem cells and is one of the important sources of hematopoietic stem cells.
According to Luo Lili, a staff member of the Sichuan Cord Blood Hematopoietic Stem Cell Bank, the most difficult part of hematopoietic stem cell transplantation is HLA (human leukocyte antigen) matching. The matching probability of matching without blood relationship is only one in tens of thousands or even one in 100,000. Most patients miss the optimal transplantation period because they cannot find suitable hematopoietic stem cells.
In October this year, the Department of Hematology, Xiangya Hospital of Central South University issued an HLA matching application to the Sichuan Cord Blood Hematopoietic Stem Cell Bank.
It turned out that a 17-year-old boy with acute lymphoblastic leukemia in the hospital needed hematopoietic stem cell transplantation.
After repeated weighing, in the end, the umbilical cord blood collected in the Affiliated Hospital of North Sichuan Medical College in 2018 was very suitable for both the number of nucleated cells and the activity of stem cells, and it was consistent with five of the six points of the patient.
On October 20, the cord blood was airlifted to Changsha, Hunan, and was transplanted with peripheral blood hematopoietic stem cells from the juvenile's family three days later.
"This is already the fifth cord blood collected in Nanchong and used for transplantation." Luo Lili said.
It is understood that among the people treated with cord blood of the Sichuan Cord Blood Hematopoietic Stem Cell Bank, adults accounted for 59.89% (age ≥18 years), of which the oldest patient treated was 74 years old; patients weighing more than 50 kg accounted for 59.75%, of which the heaviest The patient is 110 kg.
21 kinds of diseases have been treated, the longest disease-free survival after transplantation exceeds 20 years, and the longest frozen storage period of cord blood is 14 years and 7 months (April 27, 2006-December 14, 2020).
