1, doubt

The deposit of autologous library or a public library?

In response to

The economic conditions allow self storage may be considered

15, a famous 3 armour hospital maternity clinic in guangdong province, Mr Zhou, 30, is accompanied by the latter's wife. During the period of waiting, he noticed the waiting area on display in the publicity column beside the preservation of cord blood brochure. "Do you want to leave the cord blood, here has the branch of public library and autologous library, which more save?" In fact, and Mr Zhou's same question them.

Umbilical cord blood, is the shortest time after fetal childbirth broken umbilical blood from the umbilical vein. Because of the rich in hematopoietic stem cells in cord blood, so store essence is stored cord blood hematopoietic stem cells. The reporter understands, at present there are seven national legal practice of cord blood hematopoietic stem cell bank, umbilical cord blood hematopoietic stem cell library of guangdong province (hereinafter referred to as the "guangdong province umbilical cord blood bank") is one of them. The seven umbilical cord blood libraries bear the "public library" and "self library" synchronous construction, public libraries to accept voluntary donation of umbilical cord blood, maternal oriented to the whole society has the need to match; The autologous library is stored by individuals at its own cost, only for the use of depositors and relatives, matches is not geared to the needs of the whole society.

Umbilical cord blood library of guangdong province in 1999, and since 2002 began to offer to the hospital for clinical application of cord blood, as of June 2016, guangdong umbilical cord blood bank has received 300000 cord blood stem cells (including more than 280000 self storage), has accumulated 815 outbound, rescue, 673 had treatment including acute lymphocytic leukemia, dozens of diseases such as acute leukemia bone marrow cells. And costs, self storage test fee is 6800 yuan, annual 980 yuan safekeeping fee. If one-time pay, publicist said, is 19800 yuan.

So, save the self good library or donated to the public library? Sun yat-sen memorial hospital, sun yat-sen university, director of pediatric jian-pei fang said: "if the economic conditions allow, patients can consider self storage, equivalent to buy a layer of insurance."

Recently, WeChat friends circle about "self stored cord blood will not save his life" and "stored cord blood with insurance useless", has sparked the for "umbilical cord blood is it necessary to save" another round of attention. At the same time, under the background of comprehensive two child policy, more and more mothers began to think, do you want to keep the cord blood to the child.

Neonatal umbilical cord blood, and some people say that you can "fit", some say a "life insurance", but others said, this is an exaggerated business promotion. So, what should keep the cord blood for children? Autologous retained is expensive and the utilization rate is not high, donated to the public library will rapidly used by others? Self-help is referred to as a "life insurance" really can guarantee? With these questions, the reporter visited guangdong cord blood hematopoietic stem cell library and several large hospital, trying to uncover the "mystery".

2, doubt

Giving public library you can't use?

In response to

Can be used, but a lifetime to enjoy priority right of matches

"Donated to the public library, and can be used quickly, wait for when you want no?" Zhou continued doubts are put forward. To this, the relevant person in charge of umbilical cord blood bank in guangdong province to the yangcheng evening news reporter said that women, after umbilical cord blood into the public library will be available to the patients of the whole society match the query. If patients have a match, then the umbilical cord blood is indeed will be outbound. That is to say, one thousand maternal family in the future need to use the cord blood treatment, at the beginning of umbilical cord blood donation is possible to have outbound use, need to be in a public library to find matches.

But the head is also made clear that all successful donated blood of maternal (satisfy the standard of donor screening and testing qualified, and through the telephone follow-up of 6 months after the qualified for cord blood bank issued by guangdong "donate cord blood hematopoietic stem cells honor certificate". With this certificate, the donor himself (the mother) or its children, when the need for hematopoietic stem cell transplantation in the future can enjoy right of priority over a lifetime.

3, doubt

Self storage utilization rate is low?

In response to

Currently used in more blood, the future is wider

"Seems like a self storage utilization rate is far lower than the public library, saved as if also not do?" Mr Zhou wondered.

To this, the relevant person in charge of umbilical cord blood library of guangdong province told reporters that as a result of the two libraries query object is different, the query object is the patient population of public library, autologous library storage group is at its own cost, from the concept of statistics on the two do not comparable.

Third affiliated hospital of zhongshan university, said dong-jun Lin, director of the onset with cord blood is mainly used in the treatment of blood diseases, range is not too wide, so relatively utilization rate is not so high. He believes that, with the medical level gradually improve, after the application range of the cord blood will be more widely.

The reporter understands, in jian-pei fang hospital so far has been successfully implemented more than 280 cases of stem cell transplant surgery, including 10 cases of self is retained in the cord blood in the patients themselves, preserved more than 30 cases of autologous cord blood with their siblings. Jian-pei fang also explicitly pointed out that the umbilical cord blood transplantation, exactly with autograft or allograft transplantation umbilical cord blood (with others), should be according to the type of disease.

4, doubt

Why is the patient without autologous cord blood?

In response to

Some congenital diseases are not suitable for autologous transplantation

Recently, Shanghai boy of eight months since, cord blood but not for the treatment of their leukemia event let many people doubt whether the cord blood can save.

Jian-pei fang said about it, should be from the medical theory and the application case to explain the confusion. Jian-pei fang, points out that the medical theory, the etiology of leukemia with congenital and acquired two kinds, if the patient is 1 before the age of onset, clinical do consider genetic factors lead to leukemia, and autologous cord blood can't correct their own genetic defects, can not be used in the treatment of congenital leukemia.

And Shanghai 8 months boy doctor also said in an interview, due to the complexity of the cases, and for early childhood disease, congenital diseases, and congenital diseases is not suitable for autologous transplantation, so after the comprehensive consideration, suggest he adopts the scheme of allogeneic umbilical cord blood hematopoietic stem cell transplantation.

Umbilical cord blood, is the puerpera childbirth, extracted from umbilical vein remains in the blood in the umbilical cord and placenta, are generally in the hospital by a doctor or midwife collection, then passed on to take blood to cord blood bank. At present, there are seven legal practice of cord blood hematopoietic stem cell bank.

Umbilical cord blood can only treat children?

In response to

Has been successfully treated in adult patients

On the Internet, there are rumours that umbilical cord blood hematopoietic stem cells in the cell count is low, can only treat children, to this, the relevant person in charge of umbilical cord blood bank in guangdong province, said, according to the memory only for the use of autologous cord blood, there is no matches. So in clinical use, will not loss by rejection and other issues more nucleated cells, thus affecting transplant treatment effect.

Refer to the "New York blood center" (NYBC) of the national allogeneic umbilical cord blood hematopoietic stem cell transplantation of umbilical cord blood bank announced before nucleated cells of the total number of the reference standard is 0.7 x 107 / kg to 10 x 107 / kg, umbilical cord blood library of guangdong province (public library) the average cord blood frozen storage of the former nucleated cells has reached 14.55 x 108 / kg, total theory can meet the 100 kg of patients using autologous transplantation. In cord blood application in guangdong province, for example, 56% of the umbilical cord blood is used in the treatment of adult patients over the age of 18, among them, 55% of the umbilical cord blood is used in the treatment of patients with more than 50 kilograms.
