At 4:45 pm on July 12, 2007, in the delivery room of the Chengdu Women's Children's Central Hospital (formerly the Ninth People's Hospital of the City), accompanied by crying, a baby girl fell to the ground, and the obstetrician cut the baby's umbilical cord after cutting the baby's umbilical cord , Mali uses a blood collection bag to collect the blood remaining in the umbilical cord, and then immediately shipped to the cord blood stem cell library in Sichuan Province. After a series of detection and preparation procedures, frozen in a liquid nitrogen can below 196 degrees Celsius. Wait quietly at the moment of completing the mission.

In early May 2022, a 23 -year -old guy with a 23 -year -old Liu was diagnosed with acute lymphocyte leukemia in the ward of the Department of Health Medicine of the General Hospital of the Western Theater. Due to the serious condition, the doctor suggested that hematopoietic stem cell transplantation was performed immediately.

After repeated comparison and weighing, the umbilical cord blood collected by the Chengdu Women's and Children's Center Hospital in 2007 is the most qualified. Although it has been frozen for 14 years and 10 months, the activity of hematopoietic stem cells is still full.

On the morning of May 19th, the staff of the cord blood cord blood stem cell library in Sichuan Province transported this umbilical cord blood to the General Hospital of the Western Theater. After recovery, they infused in the patient's body. Treatment, the guy has now recovered and discharged.

Daughter elementary school understands the wonderful fate of umbilical blood knowledge to convey love

Mr. Cheng introduced that when his daughter An An was born, under the introduction of obstetricians and gynecologists, he learned that hematopoietic stem cells in the umbilical cord blood can be applied to dozens of major diseases such as leukemia, regenerative anemia, and lymphoma. The child leaves the umbilical cord blood, hoping to save others' lives. "

At that time, people didn't know much about umbilical cord blood, and there were fewer families who chose to store umbilical cord blood. After Mr. Cheng learned about the effect of umbilical cord blood and stored umbilical cord blood, he also actively recommended to friends around With this consciousness. "

Mr. Cheng introduced that after his daughter went to elementary school, he told her the storage cord blood. An An will be curious to ask why the umbilical cord blood is stored? How did you store it? Mr. Cheng told her in a simple and easy -to -understand truth, "Umbilical cord blood can save lives, it exists in a refrigerator like ice cream, and then take it out when it is used." Later, An An's biological class also introduced stem cells and umbilical cord blood hematopoietic blood creature in detail. stem cell.

I heard that the umbilical cord blood that was stored in that year will be rescued. Mr. Cheng still has doubts at first: after so many years of storage, the children have been in junior high school. Is the umbilical cord blood still useful? After getting a positive reply, he was very happy: "We made a proper decision at the right time, and now have a happy result. This is also a fate, a love, and warming ourselves. Also warmed others. "

Refresh the longest freezing time of umbilical cord blood in my country to remove rumors of storing cord blood useless

It is understood that this umbilical cord blood once again refreshed the maximum freezing record of the umbilical cord blood that is out of the country to save people, for 14 years and 10 months, and the record between 14 years and 7 months. blood bank.

The remarks about the use of umbilical cord blood on the Internet have never been broken. One of the views that after a few years of umbilical cord blood frozen, the "effect" gradually diminished or even disappeared, so there was no preservation value.

According to the staff of the Sichuan umbilical blood storage, the umbilical cord blood requirements for the storage temperature and the storage environment are very high. Only in the state of deep and low temperature freezing can the cells be in a dormant state, enzymes in the cells are suppressed, no electricity injury will occur. Frozen storage, the cells frozen stored in a refrigerator of -70 ° C can be saved for a year; the cells are stored in liquid nitrogen, the temperature is -196 ° C, and theoretically storage time is infinite.

Judging from the actual situation, the facts are the same. In May of this year, the umbilical blood storage in Beijing was raised a cord blood cord blood that was frozen on March 6, 1998. After recovery, the activity of hematopoietic stem cells was as high as 99.51%.
