Is blood donation really good for your health? Can it really promote new blood regeneration?

Xu Dong: The hotline is in progress for people's concerns. Hello, audience friends in front of the TV. Welcome to the Beijing hotline, we will broadcast live for you. Today, our program is broadcast live by Beijing Hotline of Beijing TV Station and Beijing Urban Management Broadcasting. Hello, I'm Xu Dong, the host of Beijing Hotline.

Yan Huang: Hello, I'm Yan Huang, the host of Beijing Urban Management Radio Zero Distance. What topic are we going to talk to you about today? Let me tell you a song title, "Let the world be full of love". This song was sung by hundreds of singers in that year, and I think everyone remembers it clearly. Now this song is called propaganda. This is the last June 14. One of our propaganda words is called "Let the world be full of love".

Xu Dong: This is the key word for World Blood Donation Day.

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

Xu Dong: First of all, let me introduce the guests who came to the studio today. They are Mr Ma Guodong, deputy director of Beijing Red Cross Blood Center, and Mr Qiu Yan, deputy director of Beijing Red Cross Blood Center. Welcome to visit.

Yan Huang: Several guests here also want to introduce them to you. First of all, I'd like to introduce monitor Hong from, and welcome all of you from Beijing Fengling. The following is about Liu Bin. As soon as I saw you, I saw black boss. It seems that your role is very popular. There is also Jiang Wei, a famous reporter from Beijing Youth Daily.

Jiang Wei: I have written many reports about blood donation and donated blood. I just saw the word blood because it is also blue, so I thought of the sea, because water is human life, just like blood, which is indispensable.

Yan Huang: Speaking of this blood, we know that the amount of blood collected in Beijing last year was 420,000 units. What is this? A * * * about 84 tons. Today, we invited two deputy directors of the blood center to introduce them. This blood donated by Beijing last year should be said to be very large. Is this amount enough for us to spend in Beijing last year?

Ma Guodong: It should be said that 42 units should be enough for blood supply in Beijing last year. However, it can be seen from the data over the years that the annual blood supply in Beijing is basically increasing at the rate of 10%. This is mainly due to the development and technical progress of some new medical technologies, which leads to an increase in blood consumption. The 420,000 units in Beijing are also a very large number in China. In China, cities with large blood consumption like Beijing, such as Shanghai, Guangzhou and Beijing, have similar blood consumption, but not as much as Beijing.

Huang Yan: Everyone has a question. Are they safe with such a large amount of blood?

Xu Dong: Yes, such a large amount of blood. Deputy Director Qiu, please tell us something about it. How can we ensure that such a large amount of blood is foolproof in this blood collection process?

Qiu Yan: Actually, there is a core problem in the process of blood supply, which is the safety of blood. The security of blood is to control every link from the whole process of blood collection and supply. Why should we vigorously promote blood donation now? First of all, we must ensure safety from the blood source and blood donation team.

We think that people who donate blood for free are giving love. They have no utility, not for money, not for any benefit, but for love. In the consultation of blood donation, if our nurses and doctors explain clearly that the blood donated by blood donors is safe, and if they have some diseases, the donated blood is unsafe, which will bring some unfavorable factors to patients and recipients. Controlling these links will ensure the safety of blood. This is the work guarantee that we do when we see our blood collection vehicle collecting blood in public. For example, when blood is collected back to the center, we do some blood treatment, blood screening and blood isolation according to the requirements of the Ministry of Health and some common blood safety guarantees in the world, as well as some observations on blood transfusion reactions during clinical blood transfusion, as well as what kind of blood you use and how to use it, so as to ensure that the blood we donate is safe for patients. The ultimate embodiment of blood safety is that the recipients can get good treatment, get certain therapeutic effect and show safety, which is its core.

Yan Huang: I would like to ask, how do you feel when you heard that we collected so much blood last year?

Hong Jiantao: More than 80 tons. We use about tons of water every year.

Xu Dong: How much water can we use a year? Isn't it more than ten tons?

Hong Jiantao: Not much, actually not much. You want tap water at home every day, and the hospital hangs a bottle every day.

Xu Dong: You still don't think it's much. What do you think? Are you going to give some?

Hong Jiantao: Give some.

Xu Dong: How does the wind chime feel?

Jing Fengling: It feels good. We don't know whether we are short of blood bank now.

Huang Yan: Do you want to offer it again?

Jing Fengling: Yes, I want to give him another one. Give him another one. What will the two of us think in the future

Xu Dong: I felt honored when I heard this figure just now. I gave blood twice in Taiwan Province. I think it's over 80 tons. Although this year's 80 tons are not counted, I think I definitely have a share of those tons in 2002. Although it is a little less, I also have a share. Have you two ever given blood?

Liu Bin: Sorry, I didn't donate blood. But as far as my physical condition is concerned, I am so fat that my blood lipid must be high. Does this meet the standard of blood donation? If the experts agree, I will give it. Because I think the 84 tons mentioned just now mainly depends on whether the quantity in Beijing is enough. If enough, I don't know much about this blood preservation, but I want to ask?

Xu Dong: I think Mr. Liu Bin asked a very professional question. How long can this blood be preserved?

Liu Bin: 84 tons. If so, is there an expiration date? Don't waste it unnecessarily. To use it effectively, after all, blood is not like a water pipe, and learning is thicker than water. Why only more than 80 tons?

Ma Guodong: Let me explain. The 84 tons mentioned just now makes it difficult for people to have an idea of what this is equivalent to. We can say that a person's blood basically accounts for 8% of the body. If a person weighs 100 kg, his blood is generally 4000 ml, which is converted into 4 kg. 80 tons is equivalent to all the blood of 20,000 people, which is basically understandable and more vivid.

Just now, Teacher Liu mentioned a blood preservation period. At present, the storage period of blood can only be 35 days, and the longest storage period is 35 days. Therefore, unlike other products, blood products can be kept all the time after production, sold when needed, and can also accumulate a certain amount of inventory. So this inventory should not be too big. If it is particularly large, there may be a waste problem. But not too little, too little. Once there is a big blood consumption peak, it is not enough.

We are also constantly exploring this job now. In the past, the stock was about 3,000 units, but now the consumption in Beijing is gradually increasing, and it is currently controlled at the level of 5000- 10000.

Hong Jiantao: Actually, this preservation process should be solved. Can I freeze it? Now everything can be frozen, such as sperm and eggs, because blood is also a part of the human body. Is that ok?

Xu Dong: Actually, yes, but we have to consider the cost, right?

Qiu Yan: At present, different ingredients have different ways to preserve blood. For example, our common solution to ischemia is red blood cells. At present, there are two main ways to preserve red blood cells. One is that we add some nutrients, such as glucose and other anticoagulants. We know that the growth cycle of red blood cells in the body is 120 days, so generally our blood is collected and kept for 35 days. Nowadays, technology has found that 70% of the blood you transfused is still capable of carrying oxygen after 48 hours of transfusion to the patient, not that I have preserved red blood cells and never died. Therefore, our current 35-day preservation method is due to the ability to transfuse this red blood cell to patients.

The freezing mentioned by the guests just now actually involves many methods of freezing red blood cells, such as freezing at-80 degrees below zero 160 degrees. Cryopreservation means that red blood cells are in a sleep state without metabolism. This method is mainly used in rare blood group, such as RH-negative blood in our Beijing blood, which is extremely rare. Once we have it, we will freeze it and use it when we need it.

Xu Dong: So how rare is this blood type?

Qiu Yan: It depends on different races. For example, the population of blacks and whites is about 15%-20%. Take Asia as an example. The population of China is only one thousandth to four thousandths.

Hong Jiantao: This World Cup is a good opportunity.

Jiang Wei: What the two experts said is quite professional, and I don't have any perceptual knowledge. I would like to ask the two directors about 84 tons of blood. Judging from your years of work experience, is there too much blood collection in Beijing?

Ma Guodong: As I mentioned just now, the annual growth rate is 65,438+00%. When we say 84 tons, we mean the data in 2005. It's only halfway through 2006, and the data is still unknown. But this 84 tons is the highest in Beijing's history.

Jiang Wei: How big is the blood bank in Beijing now? If it reaches 200 tons this year, can Beijing meet the demand?

Ma Guodong: This understanding is different. Our blood is in constant turnover, that is, we are constantly taking and using blood in clinic. We won't say that it has been preserved all the time, because just now, the storage period of blood was 35 days, and we have to go out and get it back, so we collect blood on the street every day and send blood every day.

Jiang Wei: I just heard that blood donation is mainly based on love, and love is the first step in blood donation. I donated blood nearly 20 years ago. At that time, I only tested my blood type, and then asked me if I had a history of genetic diseases. That is to say, I have love in this case, but I don't know if I have a genetic disease. What should I do?

Qiu Yan: In fact, blood transfusion medicine began in 190, and has gradually matured as a science since ABO blood group was discovered. You said that you donated blood 20 years ago, which was more than eight years ago. At that time, we had not found that hepatitis C was a blood-borne disease, which was discovered in 1989. Moreover, AIDS was discovered in 1983, when the first case of AIDS infection was found. 1980, some countries in the world began to screen for blood-borne AIDS, and our country only started to screen for AIDS in 1993, so you didn't realize the reality of these diseases in our country at that time. At that time, only one case of hepatitis B was found, but now it is very detailed.

Xu Dong: Yes, as far as I know, some of my colleagues are very tired after working all night. When you donate blood the next day, you will detect the increase of transaminase, so you cannot donate blood.

Qiu Yan: Yes, with the development of this science, in order to ensure the health of blood donors, we should also carry out health examination and consultation in blood donation. For example, at the back of the blood donation consultation form, you will be asked if there are any situations. If there is, of course, one will affect the health of blood donors and the other will affect the life safety of blood recipients. So people who can't donate blood can be divided into several categories. The first is that you have blood-borne diseases, not because you are a carrier. Others are putting off donating blood. For example, you can't donate blood to protect you because of poor rest and high transaminase caused by drinking. But after a month, your indicators are normal and you can donate blood. Some people can't donate blood because of illness, but also to ensure the health of blood donors. Before donating blood, we will do some screening and testing for some important indicators or diseases with high prevalence, such as hepatitis B, which is relatively high in China. Therefore, the blood transfusion industry has changed greatly now and 20 years ago.

Xu Dong: Ladies and gentlemen in front of the TV, you are watching the joint live broadcast of Beijing Hotline of Beijing TV Station and Beijing Urban Management Radio. Today, we talk about some topics about voluntary blood donation. As we all know, after World Blood Donation Day in June 14, Beijing also made some adjustments to blood donation, including donating blood to advocacy components. What kind of example is component blood donation and what kind of relationship does it have with our blood donors? We will discuss this problem after an advertisement.

(advertising)

Xu Dong: Welcome to continue to pay attention to the Beijing hotline live broadcast. Our program is jointly broadcast by Beijing Hotline and City Zero Distance. Before we talk about blood donation, let's take a look at the problems of audience friends.

Yan Huang: The mobile phone number 2239 gave a good attention. He said, please broadcast what blood type and quantity you need after the daily weather forecast. Please look at this index for blood donation.

Xu Dong: That's a good idea. It's very clever. Daily blood donation indicators, I think we can really do this work.

Yan Huang: Last time, HR negative blood was deficient, and some blood types were seriously deficient.

Qiu Yan: The so-called management of our blood stock, for example, the average ABO system is 3,000 to 5,000, or 5,000 to 8,000. We have a warning line and a reasonable inventory line according to different seasons. HR-negative blood also has this line. If we reach the warning line, we will rely on the media to appeal.

Xu Dong: Like the traffic station, there is a shortage of taxis at the airport now, and then the taxi driver goes. You can also send one.

Hong Jiantao: I've thought about it, too. There must be peaks and valleys. For example, people may want to donate blood during holidays and breaks. For example, when they are busy and it is hot, fewer people may donate, because people need more. If what I just said is solved, it should be no problem. If a blood donation index is published every day, because it is everyone's own business, I donate blood, but it is returned. The blood is too thick. I only smoked a little for a long time and I can't get out.

Xu Dong: Is it determined by personality? So in this case, we need to establish an early warning mechanism, or a mechanism to inform the public.

Yan Huang: You can learn about this at ordinary times.

Xu Dong: My friend with mobile phone number 3058 said that I donated blood not long ago. I want to know how your blood collection center is allocated to hospitals. Did you buy the hospital from you?

Qiu Yan: The blood we collected must be screened before returning to the blood center. In addition, we need to process these blood into different components according to clinical needs. At present, Beijing Blood Center supplies more than 300 hospitals in Beijing, and its clinical patients need blood. Every hospital should also have a blood transfusion management Committee to evaluate how much blood the patient needs, what blood to use and whether it is reasonable. On the one hand, it ensures the safety of blood transfusion, on the other hand, it can save blood transfusion resources. Because we know that it is not an easy process for everyone to give love, so we also need to save it. Determine what kind of blood the patient will receive. The blood bank in the hospital and the blood bank in our center will call to order blood, and then we will send a driver to deliver it.

Xu Dong: Let's talk about the whole problem. As mentioned earlier, this component of blood donation is a kind of blood donation that we strongly advocate after the adjustment of blood donation policy. What is component blood donation?

Qiu Yan: This is also in line with the general trend of the development of transfusion medicine. Early blood transfusion is whole blood, that is to say, blood collected on the street, if it is qualified, it will be used for transfusion. But two problems were found in the process of blood transfusion. The first is that the composition of blood is very complicated, and the second is the composition of plasma, the liquid we are talking about. There are also various tangible cellular components, such as red blood cells, white blood cells and platelets. For example, some patients don't need all the components, maybe it's just anemia. I only need red blood cells, platelets for bleeding and white blood cells for infection, so that we can divide the blood we pumped back into different components, which can solve the problem that patients don't lose unnecessary components, reduce blood transfusion reaction and save our blood resources.

Xu Dong: Is it good for the blood donors themselves?

Qiu Yan: At first, it was like this. In fact, with the development of this technology, there is now a machine. If you donate blood, we can collect anything we need.

Hong Jiantao: You can rewind it.

Qiu Yan: For example, we need platelets. We only collect your platelets and give you the rest.

Hong Jiantao: I think it's best to go out all at once. This ratio is normal in the body. I went out and came back with fewer platelets. I don't think this is good for the human body.

Qiu Yan: It has something to do with human physiology. For example, the accompanying period of platelets in the body is only10-1day, and they will be removed soon. You collect a part, which will be metabolized from the spleen.

Jing Fengling: I want to ask an expert a question. Because they are all too fat, their blood is a little unqualified. For example, exchange blood, I have heard of exchange blood, that is to say, the body needs a part, which can be filtered out and then exchanged. Is this happening?

Qiu Yan: This has nothing to do with blood donation, but it belongs to a blood therapy, which means treating hyperlipidemia. In fact, blood donation has nothing to do with obesity, as long as lesbians weigh more than 90 kg and gay men weigh more than 100 kg.

Jing Fengling: I mean, just change it and you can give it, right?

Qiu Yan: As long as there is no blood coagulation, you can give it.

Jiang Wei: People with high blood lipids can reach the standard by drinking more boiled water before donating blood. Can I have it?

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

Xu Dong: Just now, the two directors said that the blood of Hong Jiantao and Liu Bin can be used, as long as you have the desire to donate blood.

Hong Jiantao: You can't lower your blood fat by donating blood. But why do some people have other diseases after blood transfusion in the hospital, such as hepatitis B and AIDS? Why can't they control this situation? Didn't you say they all passed the inspection?

Qiu Yan: Before we carry out all tests, the blood after 1993 should be relatively safe. Before 1993, if some items were not tested, some people might get some blood-borne diseases. But at present, our blood has been screened twice, and it should be very safe after using imported reagents. Unless it is a sore period, that is to say, the blood donor is infected with the virus, but he donated blood before the body produced the indicators we want to test, and it may be transmitted to the patient at this time. So why should we recruit unpaid blood donors from low-risk groups? For example, the consultation form requires you to do a lot of behavior. For example, if you have a high-risk group susceptible to that disease, you should not donate blood. So don't underestimate this counseling test. For example, if you have it, I will test it for you. Another thing is that I am infected, but I don't have the indicators I want to test, so I can't detect it. There are blood-borne diseases.

Hong Jiantao: I used to feel dizzy, so I was scared. Besides, I'm under too much pressure because of some strange rumors about blood donation. Just like some people say that this is the essence, that's all. If it comes out, it will be less. Anyway, there are many similar ideas.

Qiu Yan: Let me interrupt, your idea is wrong.

Hong Jiantao: I know this is wrong, so I said that we should eliminate everyone's fears in the publicity.

Xu Dong: Why don't you say what you are most afraid of first?

Liu Bin: It is said that blood donation can regenerate, but he would rather believe it.

Hong Jiantao: I'm afraid of big needles. They used to be big. When they donated blood in 1980, it was a big tube.

Xu Dong: I remember 1992, when I donated blood, the needles were also very big. Let's talk about what you are most afraid of first, and let our director solve your problem in a targeted way. You must give it after today's program. You said that if you were afraid of big needles, we would exchange them for smaller ones.

Hong Jiantao: Actually, I'm afraid it's harmful to my health and my body's regenerative function. For example, if someone has high blood pressure or high cholesterol, I am always afraid of it. I said there was nothing wrong with you, but I got this disease from blood transfusion, and I was scared.

Xu Dong: Another time when I donated blood, I heard colleagues around me say that you can't donate blood, and you will gain weight soon after you donate. This statement is very popular. In addition to some previous statements, please ask the two directors to explain them to us. Is there such a problem?

Ma Guodong: As far as blood donors are concerned, the equipment used by our blood donors is disposable, and they are all qualified products recognized by the state. Therefore, in the process of blood donation, there will be no adverse effects on blood donors such as spreading diseases and infections. Please rest assured that we are very strict at this level. Moreover, we have many related departments to supervise us. We're not saying that nothing will happen. The health supervision department in Beijing will check us, how to purchase goods, and whether all qualifications are complete. This will be verified, don't worry.

Just now, you said, will others get sick? According to the inspection standards of the Ministry of Health, we have carried out two rigorous tests on all blood, that is, we have to screen it twice with different reagents, different personnel and different equipment, so as to prevent the possible adverse consequences caused by some mistakes. Therefore, it should be said that our blood is very safe under the existing scientific and technological level, not only for blood donors, but also for blood recipients.

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

Ma Guodong: Actually, we encourage people to drink more water when donating blood. In fact, this is to make blood donors feel more comfortable, make blood flow faster and prevent coagulation.

Liu Bin: Drink water for a while. You are like 8 kilos of human blood. How much can you dissolve in it?

Ma Guodong: Let me explain another example. In fact, for the human body, 20% of our blood is stored in internal organs, such as spleen. It will store a lot of blood. I just said donate 400 ml of blood, which is 10%. Needless to say, this amount of blood can be replenished from the spleen at that time. So this is totally fine.

Jing Fengling: I know many people. He is addicted to blood donation. If he doesn't give it every once in a while, he will feel uncomfortable. Is his hematopoietic function good?

Hong Jiantao: This one is very caring.

Jing Fengling: Then I heard that people who donate blood often say this. It is said that that person often donates blood. Is it his hematopoietic function? Not donating blood is particularly uncomfortable for him.

Qiu Yan: Actually, blood donation is a stimulus to human body. After you donate 400 ml of blood at a time, in addition to replenishing blood from the spleen of the organ, for example, if you drink water properly to expand the blood volume, it will stimulate your blood volume, stimulate hematopoietic cells and organs to make blood, and promote your metabolism. This is a sign of health.

Xu Dong: Sorry, I asked two serious questions. A friend with a mobile phone number of 6296 said, hello, host, why is blood donation free now, and patients have to pay so much for blood transfusion in the hospital? This is a short message. There was a phone call, and Mr. Chen also asked, why don't patients donate blood for free?

Qiu Yan: Actually, blood in our country is collected on the street for free. When we arrive at the hospital, we will charge the patient a certain fee. First of all, this fee is uniformly stipulated by the National Development and Reform Commission, and each whole blood unit is 200ml. Secondly, as a public institution, this kind of blood has certain costs in the process of collection, testing, processing and clinical distribution, such as the cost of testing reagents, the cost of equipment, the cost of blood bags for separating components, including the cost of some consumables in the collection process, which is a kind of cost.

Ma Guodong: When the National Development and Reform Commission set this blood price, it calculated the cost of blood according to the steps of blood collection, processing, inspection and storage.

Xu Dong: Blood is donated by us, but there are costs in processing, management and distribution.

Ma Guodong: From the point of view of blood, blood is priceless. You can't measure the value of blood.

Jiang Wei: For example, people who have donated blood like us, can we use blood donation for free?

Yan Huang: We have a friend whose mobile phone number is 3 149, and he has the same problem with you. He said I was a blood donor. What he cares about is that when I use blood at home, my blood type is different from mine. Can my family give priority?

Ma Guodong: This is Beijing's blood donation return policy. As a citizen of Beijing, after you donate your own blood, you can enjoy the same amount of blood five times as much as your blood donation within five years from the date of donation. This period is five times the same amount. After five years, you can use the same amount of blood for free or even for life, which is for the blood donor himself. Blood donors' immediate family members, that is, parents, spouses and children, can use the same amount of blood for free within five years.

Xu Dong: I want to continue with a more serious problem. I have to put an advertisement first. After the commercial, we continued to talk about blood.

(advertising)

Xu Dong: Welcome to continue to pay attention to the joint live broadcast of Beijing hotline and the city. Today, we talk to you about some new measures and methods of blood donation.

Yan Huang: It's an honor to donate blood. Everyone has all kinds of questions about blood donation. Here, a friend with mobile phone number 2889 asked, in April this year, I donated 400 ml at the front door. The staff said they could donate after half a year. If there is an opportunity, I want to donate it. How about less than six months?

Ma Guodong: No way. According to the People's Republic of China (PRC) Blood Donation Law, this is not allowed.

Xu Dong: It is stipulated by law.

Ma Guodong: We are strictly enforced by law.

Xu Dong: Many people ask about the amount of blood donation.

Yan Huang: A Mr. Wang asked/kloc-can people aged 0/7 donate blood?

Xu Dong: Definitely not. As long as it is below 18, many things can't be done.

Hong Jiantao: Are those bloody heads under control? I used to listen to many newspapers.

Xu Dong: Not from Beijing. Let me say one more serious question. Do not interrupt me. Regarding the amount of blood donation, many friends asked that it was not 200CC, why should it be 400CC now?

Jing Fengling: Jiang Wei, did you bid 400?

Jiang Wei: Yes.

Xu Dong: I donated 400 yuan twice. Is 400 a large number? Why? Is there any scientific principle?

Ma Guodong: Let me explain something to you. The Law on Blood Donation stipulates that every citizen can donate 200-400 yuan at a time. In other words, these 200 and 400 are original, not new discoveries now. Why do you advocate giving 400 ml here? Because for the blood donors themselves, 200 ml and 400 ml are harmless to the blood donors themselves and have no effect on your body.

But giving 400 ml is more beneficial to the recipient. For example, other people's blood, no matter how good it is, is imported as a last resort, and it is all foreign substances. Due to the mismatch between some antigens and antibodies, some blood transfusion reactions may occur. Just now, the danger of infectious diseases caused by some blood transfusion was mentioned. Here is an example. If a patient needs 800 ml of blood transfusion, if you donate 400 ml, give him two people's blood. If it is 200 ml, give him four people's blood. Our safety level is in the standard situation. Obviously, 400 is safer for blood recipients, and the prerequisite is the same for blood donors, without any damage. So from this perspective, why push 200-400 now?

Xu Dong: One more question. How much does it cost to donate blood?

Qiu Yan: Now, according to the national standard, because we count platelets, each unit is now 2.5 times 1 1 times platelets. But the platelets we collected are suspended in plasma, about 250-300 ml.

Xu Dong: Some viewers asked questions unrelated to blood transfusion. Teacher Liu asked me if I was fat. Do you often have tea in Liu Bin and Hong Jiantao? Is it useful?

Hong Jiantao: Change the theme of today's program.

Yan Huang: This friend asked Mr. Zhang from Dongcheng District what preferential policies taxi drivers have for donating blood. And where do you want to donate blood?

Qiu Yan: Actually, as a unpaid blood donor, the actions and behaviors of any people are the same. In addition to the blood collection points in our center, there are more than 30 mobile blood collection vehicles that can collect blood in busy streets and lanes of Beijing such as Wangfujing and Xidan.

Yan Huang: Are the sanitary conditions of blood collection vehicles the same as those in fixed hospitals? Some people have such concerns?

Qiu Yan: Our sanitary requirements and infection control of this mobile blood collection vehicle are completely in accordance with the requirements of the state for hospitals, and the health supervision office will also conduct regular inspections.

Xu Dong: Let me ask you one last question. Today, many friends asked many specific questions, which have a great relationship with their families and individuals. However, due to today's time, I can't answer them one by one. Want to know such a question, how to contact our blood center, and through what channels can I get the answer?

Qiu Yan: Our blood center has a hotline.

Ma Guodong: 8006 102233. If the line is busy, you can call 82079988 and transfer to our public relations department. They can answer your questions.

Yan Huang: We also have a website with many introductions.

Xu Dong: Beijing Red Cross Blood Center, you can go to this website to check the problems. Today's program is coming to an end. After the program, we will organize another voluntary blood donation. Thank you for your attention. In the next issue of our Beijing hotline, we will continue to broadcast issues closely related to your life. See you next time.
