"Blood can be regenerated but life cannot be repeated", it is such a short sentence, but it has touched many people, so that they rolled up their sleeves and walked on the blood donation car. Blood donation is an ordinary but shining little thing in life, but this faint light is sometimes the only light source in a patient's life.
Generally speaking, most of our blood types are in the ABO system, and in 2017, Jiangsu appeared a rare blood type, the only case in the world, you know, the rarer the blood type, the more precious, what is this blood type?
Common blood type
With the development of modernization, people know more and more about themselves, and the blood type that the older generation never cares about, we have begun to unconsciously remember it. In general, the public's blood type is common in A, B, AB or O blood type, and more rarely, it is the RH type that we call "panda blood".
There are very few people in the world who have "panda blood", so this special blood is also particularly precious when such special people are injured or sick and need blood transfusions. Although every hospital is basically equipped with a large blood bank, because the source of blood is uneven, sometimes it will appear that you need to use blood, but the hospital does not necessarily supply it.
Some diseases can wait, some diseases can not, because of blood problems and miss a good treatment time is not a few cases, so the hospital every year also as far as possible to call on everyone to donate blood, so that at some point in the future can be in the future for these unforeseen needs to plan.
People with different blood types cannot be transfused indiscriminately, otherwise they will cause different degrees of rejection reactions, which will be serious and even life-threatening. But there is also a special case, that is, type O blood, this type of blood is more special, their red blood surface does not have A type antigen or B type antigen, which means that it can produce two antibodies.
That is to say, if a patient with type A blood needs a blood transfusion, in the absence of emergency blood, it is also possible to transfuse type O blood, so type O blood is also called universal blood, and this type of person is also a group of people who are quite popular with those who are engaged in blood donation.
But even universal blood, in the face of special "panda blood", is powerless, so if you have the opportunity to store some rare "panda blood", whether it is for hospitals or patients, it is a very fortunate thing.
Exceptions within exceptions
I thought that "panda blood" was an exception, but there is a blood type in the world that is rarer than "panda blood", which happened in Nanjing, Jiangsu Province, in 2017, when a pregnant woman came to the local hospital for a normal obstetric examination.
Because it was close to giving birth, the doctor could not respond in time to an uncontrollable event such as heavy bleeding, so he thought of letting the mother-to-be go for a blood test in case of emergency.
However, after this examination, the doctor in charge of the treatment looked at the results of the examination and was a little confused, and even once wondered whether there was something wrong with his own machine. According to the results of the pregnant woman's examination, the woman's blood type is not recorded in China or even globally, which means that this will be the first new blood type they have found in the world.
As soon as the incident spread, the local doctors exploded, but the stakes were high, and for the sake of safety, the doctor sent the pregnant woman's blood to the local blood center office in Jiangsu Province for another test.
In fact, so far, from the statistics of the International Blood Transfusion Association, we have found more than thirty blood types, which are classified into different blood types, but the unheard of blood types on this expectant mother have attracted the attention of most people.
If the identification is really a new blood type, then the study of this blood group will make an indelible contribution in some future clinical trials. Countless people stared at the results of this examination, wanting to find out, the test report came out, the previous doctor did not read wrong, this is indeed a new blood type that has never been seen before.
But this expectant mother listened to such words but some doubts, before she also did a similar blood test, why did not check it out at that time, and blood and genetic inheritance also have a great relationship, pregnant women have not appeared in the previous generations have not appeared in this blood type, how can they suddenly have this rare blood type.
The choice of fate
The doctor made a detailed explanation for this, the pregnant woman actually existed in the ABO blood group system before, but then the blood group gene mutated, resulting in the A3 subtype allele, that is, the mutant of the A type of blood, which belongs to the weak A subtype, accounting for less than one-tenth of the blood type A, extremely rare, and before that, it has never been heard of.
For the time, this weak subtype A blood was the only new blood type that appeared for the first time in the world at that time, and after verification, the hospital's first advice to the woman was that it was best to store blood regularly, and if she suddenly needed emergency use in the future, she could only save herself on her own.
For those biologists, the genetic mutation of blood is the natural result of the evolution of nature, and we humans have been constantly breaking through ourselves since our birth, which is not only a breakthrough in the spiritual level, but also a breakthrough in physical structure.
It's just that not all genetic mutations are good, and for some bad changes in direction, people will also take the initiative to intervene in them, trying to minimize the harm suffered by people. After solving the current problem, whether this rare blood will be passed on to the next generation has become a hotly debated question, and the answer is not certain.
Even with the intentional intervention of science, with the scientific and technological means at that time, it is not 100% guaranteed that the offspring of this lady also have this weak subtype of blood, but if this gene can be retained with the birth of the child, and can be continued to the next generation, perhaps this rare blood type will one day become another kind of "panda blood", although rare, but still alive.
But if this rare gene is not passed on to the next generation, this weak A blood type may only exist in this lady, and it will disappear permanently after a short period of existence.
epilogue
There is also speculation that not everyone can check their blood for genetic mutations at any time, whether it will be that in the case that we do not know, in fact, there are people like this mother-to-be, who have this blood type, in fact, this is also an inaccurate thing.
Blood type is a very wonderful thing, with the same blood type, in a way, will make us have a wonderful sense of belonging, but if you have a rare "panda blood" will also give people a very special feeling of their own, do you know your own blood type?
