Waiting for 5 years, this umbilical cord blood was born for her

On August 19, the mountain city was still hot in summer. Xu Guochao dragged heavy small gas -phase liquid nitrogen jars and walked along the road into Chongqing Medical University Children's Hospital. The jar was equipped with a bag of umbilical cord blood stem cells that had not yet recovered.

At this moment, in the streaming ward on the 9th floor of Building 6, the 5 -year -old Nanchong girl Qin Qin was lying quietly on the hospital bed. Umbilical cord blood stem cells.

When many "quasi -parents" are still struggling with whether the umbilical cord blood is useful, Qin Qin has been waiting for it for more than 5 years.

It turned out that when Qin Qin was two months old, due to "pale complexion", he was found to have heavy β -thalassemia in the hospital.

Mediterranean anemia is a genetic hemolytic disease caused by genetic defects. Β thalassemia can be divided into light, severe, and intermediate types according to the severe condition. Among them, patients with severe thalassemia. It is often difficult for patients to live for 5 years if they are not treated in time.

Since the diagnosis is confirmed, Qin Qin has been "seeing a doctor" under the leadership of his parents. The doctor told them that hematopoietic stem cell transplantation is the only way to cure thalassemia. Before that, he needed regular blood transfusion and iron exhaust drugs.

The blood transfusion iron is not a long -term plan for patients with severe thalassemia. As the age increases, the blood transfusion is becoming more frequent. From the beginning of the initial two or three months, it will be lost once every two or three months. The amount of blood transfusion will gradually increase, and Qin Qin's comprehensive treatment costs bring a heavy economic burden on the family.

Bleeding stem cell transplantation is actually the bone marrow transplantation we often say. It is the patient who receives a large dose of radiotherapy or chemotherapy first, and sometimes combined with other immunosuppressive drugs to remove the tumor cells and abnormal clone cells in the body, and then return to the self or others. Bleeding stem cells, reconstruction of normal hematopoietic and immune function.

However, hematopoietic stem cell transplantation needs to be equipped with HLA. Simply put, it is like a key lock. The success rate of the matching type without blood relationship is very low.

Parents' bone marrows are inappropriate, and the Chinese bone marrow storage has not found a suitable hematopoietic stem cells. The doctor told Qin Qin's parents that a quarter of the brothers and sisters of the compatriots are the most likely to have the highest probability of all sources of hematopoietic stem cells.

In the case of a obstetrician determined that the belly was a healthy baby, at about 11 am on October 15, 2020, in the delivery room of the Chengdu Women's and Children's Center Hospital, Qin Qin's compatriots fell to the ground and helped the birthplaces Ye Ying ramically cut the baby boy. Umbilical cord, and use a blood collection bag to collect the blood residual in the umbilical cord, transport to the cord blood stem cell library of umbilical cord blood in Sichuan Province. After a series of testing and preparation, the frozen deep -low temperature jars at minus 196 degrees, waiting for the recovery of the recovery that moment.

Fortunately, Qin Qin matched with his younger brother, and the 10 points were fully combined. In July of this year, the Sichuan umbilical blood storage received the "Notice of Umbilical Cord Blood Library" from Chongqing Medical University Children's Hospital.

In order to ensure the safety and effectiveness of umbilical cord blood, there will be full -time staff in the umbilical blood bank to transport the umbilical cord blood stem cells to the hospital where the patient is located, and the resurrection is given to the doctor.

Xu Guochao of the clinical service department of Sichuan umbilical blood storage is responsible for this "express task": carefully check the information of the umbilical cord blood, ensure that it is taken out of the liquid nitrogen tank after correctness, put it in a small gas -phase liquid nitrogen tank, and then Xu Guochao must be transported to it one day in advance to it to the day in advance to Chongqing.

At 8:30 am on August 19, 2022, Xu Guochao was in the preparation room of the hospital and waited for the doctor's notice. About an hour later, Xu Guo Super Mattically took out the umbilical cord blood from the liquid nitrogen tank. After confirming that it was correct, he was placed in warm water to recover, and then handed it over to the doctor to reintegrate his life for Qin Qin.

Sichuan umbilical cord blood outlet reached a new high

The umbilical cord blood is the blood that is newborn, the umbilical cord is ligated and the blood remains in the umbilical cord and the placenta, and is one of the three sources of hematopoietic stem cells. According to the "Management Specifications for hematopoietic stem cell transplantation technology (2017)" issued by the National Health and Health Commission, umbilical cord blood stem cell transplantation technology has now been used in the treatment of 11 major diseases such as leukemia, regenerative disorder anemia, thalassemia, and lymphoma. At the same time, in terms of regeneration medicine, with the continuous deepening of basic research, research projects such as CAR-T immune cell therapy of cord blood and autism, and cord blood sources are also undergoing.

In the first half of 2022, a total of 134 umbilical cord blood from the cord blood storage in Sichuan, an increase of 55.81%year -on -year, 130 of which were used for clinical treatment and a total of 130 patients were cured; 4 cord blood cord blood was used for clinical basic research and scientific research. Among the umbilical cord blood in the first half of the year, the longest freezing period of freezing is up to 14 years and 10 months. The activity is still full during recovery, which meets clinical application needs.

Among the patients, 104 were adults greater than or equal to 18 years old, accounting for 80%; 26 young children patients, accounting for 20%. 78 patients weighing more than 50 kg, accounting for 60%, and a maximum weight of 93 kg. From the perspective of treatment of diseases, the top 5 are leukemia, lymphoma, osteoma hyperplasia syndrome, regenerative disorder anemia, and thalassemia, accounting for 71.54%, 11.54%, 6.92%, 4.61%, and 3.08%, respectively.
