Is donating blood really good for you? Does it really promote the regeneration of new blood?

Xudong: The people care about things, hotline in progress. Hello viewers in front of the TV, welcome to our live broadcast of "Beijing Hotline", today our program is jointly broadcast by Beijing TV's "Beijing Hotline" and Beijing City Management Radio's "City Zero Distance" program. Hello, I am Xudong, the host of Beijing Hotline.

Huang Yan: Hello, I'm Huang Yan, the host of Beijing City Management Radio's "City Zero Distance" program. What topic are we going to talk to you about today? I'll start by giving you a song title, "Let the world be full of love", this song was once sung by a hundred singers in the year, we must remember, and now this song title has become a propaganda word, which is just past June 14th we have a propaganda word called "Let the world be full of love".

Xudong: This is the theme lyrics of the World Blood Donation Day.

Huang Yan: Today we are going to talk to you about the topic of blood donation, some people say that this is not a cliché, of course not, because the Beijing Municipality from now on in the donation of blood there are some new changes, so today we come to talk about this topic.

Xudong: First of all, I would like to introduce the guests who are coming to the studio today, they are Mr. Ma Guodong, deputy director of the Beijing Red Cross Blood Center, and Qiu Yan, deputy director of the Beijing Red Cross Blood Center, welcome to both of you.

Huang Yan: this side of the several guests are also introduced to you, first of all, to introduce you to Hong Jiantao Hong class president, and Jing Feng Ling welcome you. The following to introduce to you is Liu Bin, a see you see the black boss, it seems that your role is very deep. There is also the famous reporter Jiang Wei from the Beijing Youth Daily.

Jiang Wei: I've written a lot of reports on blood donation, and I've donated blood before, and just now I saw the word "blood" because it's also blue, so I thought of the sea, because water is people's life, and it's indispensable to people's lives, just like blood.

Huang Yan: Speaking of this blood, we know that last year's Beijing blood collection volume of one *** is 420,000 units, this is exactly how much? A *** is about 84 tons. Today we asked the two deputy directors of the blood center to give us an introduction, last year, Beijing donated this blood should be said to be very much, this amount is not enough for our Beijing last year's dosage?

Ma Guodong: It should be said that 42 this unit should be enough for Beijing's blood supply last year. But we can see from the data of the past years, Beijing's annual blood supply is basically at a rate of 10% in the growth. This is mainly due to the development of new medical technologies and technological advances that have led to an increase in the amount of blood used. Beijing's 420,000 units is also a very large number in the country, nationally speaking, like Beijing so much blood in the city, such as Shanghai and Guangzhou and the city of Beijing's blood is about the same, but they are not as much as Beijing.

Huang Yan: We have a question, such a large amount of blood, they are safe?

Xudong: Yes, such a large amount of blood, Qiu, deputy director of how to tell us how to ensure that such a large amount of blood in the process of blood collection are foolproof.

Qiu Yan: In fact, there is a core issue in the blood supply process, which is the safety of blood. The safety of the blood to ensure that we from the entire process of blood collection and supply of the entire process of each link in the control. Why do we now vigorously publicize blood donation, first of all, from the source of blood, blood donation team to ensure safety.

We believe that people who donate blood for free are giving love, they don't have any utilitarianism, they don't do it for money, they don't do it for any benefit, they just do it for love. In the blood donation consultation, if our nurses and doctors explain clearly the donor's health to donate blood is safe, if they have some kind of disease, donate blood is not safe, will let the patient recipient also bring some negative factors, these links of control to ensure the safety of blood. This is what we do to ensure that we can see in public the environment in which our blood collection trucks collect blood. For example, when the blood is collected and returned to the center, according to the requirements of the Ministry of Health of China, we do some blood processing, blood screening, blood isolation, as well as to the process of clinical blood transfusion, some observation of the transfusion reaction, as well as which kind of blood you use and how to use the blood, and so on, each of these links is to ensure that the blood we donate is safe for use in patients. The safety of blood is ultimately reflected by the fact that it is safe for patients to receive it. The safety of the blood is ultimately reflected in the recipient can get good treatment, get a certain therapeutic effect, show the safety, which is the core of it.

Huang Yan: I would like to ask the guests here friends heard that we have collected so much blood last year, what do you feel?

Hong Jiantao: more than 80 tons, a family we use every year is probably also calculated by tons of water.

Xudong: How much water can we use a year, more than a dozen tons, more than this, right?

Hong Jiantao: not much it, in fact, not much ah, you want to think about the tap water at home every day, the hospital every day hanging bottles in the tick.

Xudong: you still feel that not much, then what do you feel, intend to offer some?

Hong Jiantao: Offer some.

Xudong: What does Feng Ling feel?

Jing Feng Ling: I feel pretty good, we now have a blood bank do not know if there is a shortage now.

Huang Yan: still want to dedicate again?

Jing Fengling: Yes, still want to dedicate again, and then get him a book, turn back to our two old a book still think how it is.

Xudong: I just listened to this number, I also feel quite honorable, I donated blood twice in the station. I think 80 or so tons, although this year's 80 or so tons are not counted, I think 02 that how many tons in the surely also have my share, although less, but also have a share. The first thing you need to do is to get your hands on a new pair of shoes or boots.

Liu Bin: Sorry, I have not donated blood. But on my current physical condition, so fat, lipids must be high, this meets the criteria for blood donation? The experts said that I will dedicate. Because I think just said 84 tons, it mainly depends on the amount of our Beijing enough not enough, if it is enough, this blood preservation I do not quite understand, but I would like to ask?

Xudong: I think Mr. Liu Bin asked a professional question, how long can this blood donation be saved?

Liu Bin: 84 tons, more words, is not there an expiration date, do not have unnecessary waste. To effectively use, blood, after all, not like a water pipe a twist, learning is thicker than water, why only more than 80 tons?

Ma Guodong: Let me explain, just said 84 tons, it is difficult to have a feeling that this is equivalent to a what kind of understanding. We can put it this way, a person's blood basically accounts for 8% of the body. If a person is 100 pounds of body weight, his blood is generally 4000 milliliters, converted into weight is four kilograms. 80 tons is equivalent to 20,000 people all over the body of all the blood, basically can be understood in this way, so more image.

Just now Mr. Liu mentioned a blood preservation period, this blood preservation period at present, we can only save the way to save 35 days, the longest preservation period is 35 days. So the blood of this product is not like other products, the production down can always be put, when the need when when to sell, but also can accumulate a certain amount of inventory. So this inventory can not be too large, if it is particularly large, there may be a problem of waste. But it can't be too small, and if it is too small, it will not be enough when there is a big blood rush.

We are now in the process of figuring out how to do this, and the previous inventory was about 3,000 units, but now the dosage in Beijing is gradually increasing, and is now controlled at the level of 5,000-10,000.

Hong Jiantao: In fact, this process of preservation should be able to solve it, is it possible to freeze? Now everything can be frozen, like sperm and eggs can be frozen, because blood is also part of the human body, is not this also can?

Xudong: In fact, it is possible, but we have to consider the cost of it, is it not?

Qiu Yan: We currently have different ways of preserving blood for different components. For example, we commonly can solve your ischemic situation, anemia is red blood cells. Red blood cells are currently preserved in two main ways, one is that we add some nutrients, such as glucose and other anticoagulant things to save, we know that the red blood cells in the body of its own growth cycle is 120 days, so the general collection of blood out of our blood, we save it to 35 days, the current scientific and technological discovery of the blood when the blood transfused to the patient for 48 hours, you transfused into the blood 70% of blood and oxygen-carrying capacity, not to say that I save the blood, but also to save the blood, but also to save the blood. It is not that I save the red blood cells are not dead is good, it can continue to save not die, but you have to let the patient transfused in to play a function. So we are now preserving the way 35 days, is to transfuse to the patient this red blood cells still have the ability to say.

Just now the guest of honor mentioned the freezing, in fact, when the freezing of the red blood cells there are many methods, such as negative 80 degrees negative 160 degrees of freezing, cold is to make the red blood cells do not metabolism to maintain a sleep state and then frozen, this method is mainly used in rare blood types, such as our Beijing blood in the RH-negative blood, this rare blood type is particularly rare, once the blood type, we have cryopreservation, we have a cryopreservation of the blood cells. The first time I saw this, I was able to get the money to pay for it, and then I was able to get the money to pay for it, and then I was able to get the money to pay for it.

Xudong: How rare is this blood type?

Qiu Yan: It depends on the ethnicity, for example, in black and white populations it's about 15-20%. In Asian populations, such as China, it's only 1 in 1,000 to 4 in 1,000.

Hong Jiantao: This World Cup is a good opportunity.

Jiang Wei: two experts said quite professional, I do not have any perceptual understanding. I would like to ask the two directors 84 tons of blood, in your work so many years of experience in Beijing's blood collection is considered a lot?

Ma Guodong: Just now I also mentioned, every year is to 10% of the rate of growth again. We say that this 84 tons refers to the data of 05 years, and now only half of 06 years, the data is not yet known. But this 84 tons is the highest in Beijing's history.

Jiang Wei: How much blood is stored in Beijing now? If it gets to 200 tons this year, will Beijing be able to meet the demand?

Ma Guodong: This understanding is not the same, our blood in the constant turnover, that is, in the constant collection of blood and clinical also in the constant use of blood, one side in and one side out, will not say that has been stored, because just said, the blood on the 35-day retention period, must be constantly out and collected back, so we are every day in the street collection of blood, and also every day to send the blood.

Jiang Wei: Just now I heard, voluntary blood donation is mainly to love, love is the first step of blood donation. I donated blood nearly 20 years ago, when only measured my blood type, and then asked me whether I have a history of genetic diseases, that is to say, in this case I have love, but do not know whether I have a genetic disease should do?

Qiu Yan: In fact, transfusion medicine from 190 years, after the discovery of the ABO blood group as a branch of science is also gradually mature development. You said that 20 years ago you donated blood, that time was eight years ago. At that time we hadn't discovered that hepatitis C was a blood-borne disease, it was discovered in '89. And AIDS was discovered in '83, the first case of AIDS was detected at that time, and it was in '80 that some countries in the world started screening for blood-borne AIDS, and it was only in '93 that we started screening for AIDS, so you didn't realize at that time that these diseases were a reality in our country. At that time we were screening for only one Hepatitis B. But now the screening has become very detailed.

Xudong: Yes, as far as I know among my coworkers, someone who worked a very tiring night, the next day when they donate blood, they will be tested for elevated transaminases, and they can not donate blood.

Qiu Yan: Yes, with the development of this science, we are doing the work of blood donation in order to ensure the health of the donor also need to carry out health checks and counseling. For example, in the back of the blood donation counseling form will ask you a variety of conditions have not, if so, of course, one is to affect the physical health of the donor, the other is to affect the safety of the recipient's life. Therefore, there are several categories of people who are not allowed to donate blood. The first one is that you have a blood-borne disease and you are a carrier, so you can't donate blood. There are also those who can't donate blood, for example, you can't donate blood due to poor rest and elevated aminotransferases caused by alcohol consumption, so you can't donate blood in order to protect you. But after a month, you can donate blood when your level is normalized. There are also some reasons why you can't donate blood for disease reasons, also to ensure the health of the donor, we will do some screening and testing on some important indicators or diseases with high prevalence, like hepatitis B which is relatively high in the Chinese population, before donating blood. So the industry of blood transfusion now and 20 years ago itself has changed dramatically.

Xudong: The audience in front of the TV, you are watching the Beijing TV "Beijing Hotline" and the Beijing City Management Radio "City Zero Distance" for your joint live broadcast. Today we are talking about some of the topics of blood donation, we all know that after the June 14th World Blood Donation Day, the Beijing Municipality of blood donation work has also made some adjustments, including the advocacy of component blood donation. What kind of example of component blood donation is, and what kind of correlation it has with our donors, we'll explore this issue after a commercial.

(Ad)

Xudong: Welcome back to our live program, brought to you jointly by Beijing Hotline and City Zero. Before we talk about component blood donation, let's take a look at the questions from our viewers.

Huang Yan: cell phone tail number 2239 mentioned a very good attention, he said please in the daily weather forecast, broadcast a need for what blood type, how much, we look at this index to donate blood.

Xudong: This idea is fantastic, brilliant. Daily blood donation index, I think we can really do this work.

Huang Yan: The last time HR negative blood shortage, not some blood type shortage is very serious.

Qiu Yan: the so-called management of our blood inventory, for example, ordinary ABO this system is 3000 to 5000, or 5000 to 8000, we have a cordon and reasonable inventory line according to the different seasons. HR negative blood also have this line, if to the cordon we have to rely on the media to appeal.

Xudong: like the traffic station said the airport is now short of a large number of cabs, and then cab drivers went, you can also send a this.

Hong Jiantao: I have thought about this problem, there must be peaks and valleys, such as vacation time, rest when people may want to go to donate blood, like busy time, and the heat of the day may be donated by a little less people, because the human body needs a greater amount of some. If the problem mentioned by me just now is solved, there should not be any problem. If a blood donation index is announced every day, because it is all about everyone, I have donated blood, but was returned, the blood is too thick, pumping half a day only a little, out of the way.

Xudong: is not a character decision. So like this we also need to establish a mechanism for early warning, or a mechanism to inform the public.

Huang Yan: in the ordinary day can understand this.

Xudong: cell phone tail number 3058 friend said, I donated blood not long ago, I would like to know how you blood collection center is allocated to the hospital? Is the hospital to buy from you?

Qiu Yan: We collect blood back to our blood center first to be screened. In addition, we have to process the blood into different components according to the clinical needs. At present, Beijing's blood center is supplying more than 300 hospitals in Beijing, its clinical patients need blood, each hospital should also have a blood transfusion management committee, the first to evaluate how much blood this patient needs, what kind of blood, whether it is reasonable. This ensures the safety of blood transfusion on the one hand, and saves blood transfusion resources on the other. Because we know that it is not an easy process for everyone to give love, so we also need to economize. Set this patient to transfuse what blood, will be by the hospital's blood bank and our center's blood bank call, set the blood, and then we send a driver to send over.

Xudong: say a little bit of the whole topic, said earlier this component blood donation, this is our blood donation policy adjustment, strongly advocate one, what is the component blood donation?

Qiu Yan: This is also in line with the general trend of the development of transfusion medicine. Early blood transfusion is the whole blood, that is to say, everyone in the street collection of the blood test qualified to take to the transfusion. But in the process of blood transfusion, two problems were found, the first is that the components of blood are very complex, one is the plasma component, we say liquid. There are also various tangible cell components, such as red blood cells, white blood cells, platelets and so on. Like some patients do not need all the components, he may only anemia, I only need red blood cells, I bleed only need platelets, I infected only need white blood cells, so we will draw back the blood into different components, so we can solve the problem of the patient does not transfuse his unneeded components to reduce the transfusion reaction, and in addition can save our blood resources.

Xudong: Is this not also good for the donor's own body?

Qiu Yan: initially, in fact, the development of this technology, there is now a machine, you come to donate blood can achieve what we need we collect.

Hong Jiantao: It can also go back again.

Qiu Yan: For example, we need platelets, we only collect your platelets, the other can also be transfused to you.

Hong Jiantao: I think it would be better to go out at once, this ratio is still normal in the body. Out and back platelets less, this I think the human body is not.

Qiu Yan: This is related to the physiology of the human body, for example, platelets in the body of its own companion period of only 10-11 days, will soon be cleared by themselves. You collect part of the other from the spleen will be metabolized to replenish.

Jing Fengling: I want to ask the experts a question, like the two of them so fat, their blood is a little less qualified. For example, blood exchange, I originally heard of blood exchange, that is to say, the body needs a part of the body can be filtered and then changed back, there is such a thing?

Qiu Yan: This has nothing to do with blood donation, but belongs to a kind of blood treatment, that is to say, the treatment of high blood fat. In fact, blood donation and obesity has nothing to do with, as long as the weight of the lesbian reached more than 90 pounds, male comrades reached more than 100 pounds can be dedicated.

Jing Fengling: I mean, as long as they are changed, they can be donated, right?

Qiu Yan: As long as there is no coagulation can be donated.

Jiang Wei: people with high blood fat to drink more water before donating blood can reach the target can be donated?

Liu Bin: What she just said means you need your platelets, the fat in your blood is back.

Xudong: Just now the two directors said, Hong Jiantao and Liu Bin's blood can be used, as long as you have the desire to donate blood can be.

Hong Jiantao: You want to donate blood to lower blood fat is impossible. But why some people in the hospital through blood transfusion will produce other diseases later, such as hepatitis B, AIDS why can not control this situation? Not that all have been tested?

Qiu Yan: Before we implemented all the tests, the blood after '93 should be relatively safe. Before '93, there were still some programs that didn't add testing, so some people might get some blood-borne diseases. But at present, our blood should be safe after two screenings with imported reagents. Unless there is a sore period, that is, the donor is infected with a virus, but before the body produces the indicators we want to test, he donates blood, and at this time there is a possibility of transmission to the patient. That's why we recruit unpaid blood donors from low-risk groups. For example, the counseling form asks you not to donate blood if you have a lot of behaviors, such as having a high-risk group that is prone to contracting that disease. So we should not underestimate this counseling, testing, for example, you have I give you a test, there is another I am infected, I want to test the indicators do not have, the same test does not occur, the occurrence of blood-borne diseases.

Hong Jiantao: I used to old dizzy needles, so I'm afraid, and I'm also too much pressure on some of the strange rumors of blood donation, like some people say this is the essence, just so much, get it out of you less, anyway, there are similar to a lot of such concepts.

Qiu Yan: I'm going to interrupt.

Hong Jiantao: I know this is not right, I'm just saying, we should be in the propaganda to eliminate the fear of the people.

Xudong: You first say what you are most afraid of?

Liu Bin: How to publicize that blood donation is fine, you can regenerate, but he would rather believe that.

Hong Jiantao: I'm afraid of the big needles, which used to be particularly large. Eight years they donated blood at that time, that will be the big thick tube.

Xudong: I remember when I donated blood in 92 the needle was also very large. You first say, the most afraid of what, so that our director targeted to solve your problem, after today's program you must offer can not. The first thing you need to do is to get your hands on a new needle, and then you'll be able to get it to work.

Hong Jiantao: In fact, I'm afraid of the body is not good, the body's regenerative function, for example, some people have high blood pressure disease, or cholesterol is relatively high this kind of, I'm afraid of this old. Originally said you do not have any disease, the result of blood transfusion has this disease, I am afraid of this.

Xudong: There is also a time when I donated blood, I listened to my colleagues around me said, can not be donated, you donated soon to be fat. This statement is very popular, coupled with some previous statements, please two directors to explain to us, there is such a problem?

Ma Guodong: As far as blood donors are concerned, the equipment used by our donors are disposable, and they are all qualified products recognized by the state. So that in the process of blood donation, will not give the donor any adverse effects, such as the spread of disease and infection, this please rest assured that we are very strict in this gate. And we also have a lot of related departments will supervise us, not we say that all right on all right, the Beijing health supervision department will check us this, we how to buy, all the qualification is complete, this will have the examination, so this point can rest assured.

Just now you said, others will not get sick. We in accordance with the Ministry of Health's inspection standards, all the blood are strictly two times the test, that is, to carry out two different reagents, different personnel, different equipment for screening, so as to prevent the possible adverse consequences caused by some errors. So it should be said that with the current level of technology, our blood is very safe, not only for the donors, but also for the recipients.

Hong Jiantao: They say drinking more brown sugar water before donating blood can dilute the blood?

Ma: In fact, we encourage people to drink more water when donating blood, in fact, this is in order to donate blood in the process, the donor can be more comfortable, the blood flow faster, to prevent the phenomenon of coagulation.

Liu Bin: temporary drinking water this, you like human blood 8 kilograms, which can be dissolved into the inside how much?

Ma Guodong: I explain another example, in fact, for the human body, our body has 20% of the blood are stored in the internal organs, such as the spleen. It will store a large amount of blood, I just said to donate 400 milliliters of blood, that is 10%, this amount of blood needless to say reconstructed, at that time can be replenished from the spleen. So this is no problem at all.

Jing Fengling: I know a lot of people, he donated blood addiction, every once in a while not to dedicate it is difficult, is not his hematopoietic function is good?

Hong Jiantao: people that are loving.

Jing Fengling: Just so, I heard that people who often donate blood have this argument. Said that person often donate blood, is not his hematopoietic function, he does not donate blood especially difficult.

Qiu Yan: blood donation is actually said to be a process of stimulation of the muscle, you once donated 400 ml of blood, in addition to the muscle from the organs of the spleen in addition to replenishment of blood, such as you drink water properly to expand the blood volume, this time will stimulate the volume of your blood, stimulate the hematopoietic cells and hematopoietic organs to make blood, so as to promote your metabolism, which is a healthy performance.

Xudong: interrupt, I ask two serious questions, cell phone tail number 6296 friends said, hosts you good, why is now free blood donation, patients in the hospital blood transfusion but also charge so much money this is the text message. There is a phone call Mr. Chen also asked this, why free blood donation, patients do not have free blood?

Qiu Yan: In fact, this is the case, our country's blood, we are unpaid in the street collection to the hospital to the patient to charge a certain fee. First of all this cost is the National Development and Reform Commission unified regulations, each whole blood unit is 200 milliliters. Secondly, we as a business unit, this blood in the collection, testing and processing, clinical distribution process has a certain cost, such as the cost of testing reagents, equipment costs, separation of components of the cost of the blood bag, including the collection of some of the cost of consumables, which is the cost of costs.

Ma Guodong: The National Development and Reform Commission to develop this blood price is in accordance with the blood collection, processing, testing, storage and so on to calculate the cost of blood.

Xudong: blood is our voluntary donation, but there is a cost of processing, management and distribution.

Ma: From the point of view of blood blood is priceless, you can not measure the value of blood.

Jiang Wei: For example, people like us who have donated blood, can we use donated blood without compensation?

Huang Yan: We have a friend here with cell phone tail number 3149 who has the same question as you, he said I am a blood donor, and he is concerned that when my family members use the blood, I have a different blood type than my family members, so can my family members be given priority?

Ma Guodong: Beijing's blood donation return policy is stipulated in this way. As a citizen of Beijing, after you donate your own blood, you can enjoy five times the amount of blood you donate within five years from the day you donate blood. This period is five times the amount of blood donated, and after five years, you can use the equivalent amount of blood free of charge for the rest of your life, which is for the donor himself. For the donor's immediate family members, that is, parents, spouse and children, the equivalent amount of blood can be used free of charge within five years.

Xudong: I'm going to move on to a more serious issue, and I'm going to have to play a commercial, and after that we'll move on to blood.

(ad)

Xudong: Welcome to the joint broadcast of Beijing Hotline and City Zero, where today we are talking to you *** together about some new measures and methods of blood donation.

Huang Yan: blood donation is honorable. We have a variety of questions about blood donation, here a cell phone tail number 2889 friend asked, in April this year I donated 400 ml in front of the door, the staff said that six months later can still be donated, there is an opportunity that I would like to donate, less than six months can be?

Ma Guodong: no. This according to our country's Chinese people **** and state blood donation law is not allowed.

Xudong: The law has provisions.

Ma Guodong: the law has provisions, we strictly enforce this.

Xudong: Many people ask about the amount of blood donated.

Huang Yan: A Mr. Wang asked if a 17-year-old can donate blood.

Xudong: Definitely not, as long as the age of 18 years old or less, a lot of things can not be done.

Hong Jiantao: those blood head control? I used to hear a lot of newspapers.

Xudong: not Beijing. Let me say another serious question, do not interrupt me. On the issue of the amount of blood donated, many friends asked the original is not to donate 200CC, now why 400CC?

Jing Fengling: Jiang Wei you donated 400, right?

Jiang Wei: Yes.

Xudong: I donated 400 cumulatively on two occasions. 400 is a lot, why? Is there a scientific principle?

Ma Guodong: This to explain to you, we from the blood donation law in the provisions of each citizen to donate blood can be donated 200-400. that is to say, this 200 and 400 are the original existence, and is not now a new discovery. Why do we advocate the donation of 400 milliliters? The reason is that 200 ml and 400 ml are not harmful to the donor himself, and they have no effect on his health.

But donating 400 milliliters has more benefits for the recipient. As an example, other people's blood, no matter how good it is, is transfused under compelling circumstances, are foreign substances, this foreign substance, due to some antigen-antibody mismatch, there may be some transfusion reactions, there are some just now everyone has mentioned about the danger of some transfusion of infectious diseases. Here is an example, if a patient needs to enter 800 milliliters of blood, if you donate 400 milliliters of two people's blood transfused to him, if it is 200 milliliters of four people transfused to him, our level of safety are in a standard situation, obviously 400 for the recipient of the blood safer, the prerequisite for the donor is the same again, there is no damage, so from this

Xudong: There is also a question about how much blood is needed for component donation?

Qiu Yan: Now in accordance with national standards, because we are based on the number of platelets is according to its number, now each unit is 2.5 times 10 11 times the number of platelets. But say we pick out the platelets are suspended in the plasma, about 250-300 milliliters.

Xudong: There are also questions from the audience that are not related to blood transfusion, Mr. Liu asked I'm a bit chubby, and I want to ask Liu Bin and Hong Jiantao do you often drink tea? Does it work?

Hong Jiantao: change the topic of today's program.

Huang Yan: This friend asked, Mr. Zhang in Dongcheng District, said taxi drivers to donate blood have any preferential policies? And where to donate blood to donate blood?

Qiu Yan: In fact, for blood donation, as a voluntary blood donation action and behavior for any population is the same. In addition to our center has a blood collection point, Beijing's busy streets like Wangfujing and Xidan have more than 30 mobile blood collection vehicle, you can go there blood.

Huang Yan: Is the sanitary condition of the blood collection trucks the same as the fixed hospitals, and some people will have this concern?

Qiu Yan: We about this mobile blood collection car health requirements and infection control is completely in accordance with the national requirements for hospitals to do, health inspection and supervision will also be regularly inspected.

Xudong: I finally asked a question, today many of my friends have asked a lot of specific questions, and their own families, individuals have a great deal to do, but because of the relationship between the time of the day, can not be answered one by one, if you want to know this kind of question, how can we contact the blood center, through what channels to get answers?

Qiu Yan: Our blood center has a consultation hotline.

Ma: 8006102233. If this number is busy, you can call 82079988 can be transferred to our public relations section, they can give you answers.
