中新网南京1月18日电 (王琦)今天，记者从江苏省血液中心得知，江苏又发现了一种稀有血型。据分析，它在人群之中只有五十万分之一的比例，它使得稀有血型的图谱突破了50种。

Nanjing Beijing January and report (boyer)today,Reporters from jiangsu province that blood center,Jiangsu and found a rare blood type.According to the analysis,It is in the crowd only one over five hundred thousand scale,It makes rare blood type map breakthrough of fifty.

　　近日，江苏一家医院的医生发现一名男性患者在手术输血时出现排异反应，几乎血型全部无效，经过江苏省血液中心检验发现，患者的血液含有A型抗原和B型抗原但又不属于AB型血，显然它是一种新的稀有血型。研究人员称之为BA亚型。

recently,Jiangsu a hospital doctors found a male patients in operation in the middle of a transfusion reaction,Almost all blood type is invalid,After inspection found that blood center of jiangsu province,Patients with blood type A and type B antigens antigen but do not belong to AB blood,Apparently it is a kind of new rare blood type.The researchers called BA subtype.

　　江苏省血液中心输血研究室主任刘衍春说：“BA亚型的出现在十八到五十万分之一，在人群中比例比较少。”BA亚型的发现使得正在筹建的稀有血型图谱突破了50种，专家表示建立新的稀有血型图谱意义重大，一旦有患者需要稀有血液，血液中心就能从图谱中找到相同血型的人，从而及时采血，帮助患者度过生命危险。

Jiangsu blood center blood transfusion research director LiuYanChun said:"BA subtypes of appeared in the eighteen to one over five hundred thousand,In the crowd proportion is less."BA subtype discovery makes is the preparation of rare blood type map breakthrough of fifty,Experts say to build new rare blood type map is of great significance,Once patients need rare blood,Blood center can from the map to find the same type of person,So as to timely draw blood,Help patients have life risk.

　　但是为什么不能使用号称万能血的O型血，反而要花费巨大的人力成本去发现稀有血型建立稀有血型图谱呢？刘衍春解释：“O型血的人的血浆中有抗A和抗B，把全血给病人输的话，它的抗A和抗B就可能造成A型和B型病人的红细胞被破坏。”同型输血则完全不存在这些问题，因此从这个意义上说，每一个新的稀有血型发现都意味着一批潜在的患者获得了生命保障。(完)

But why can't use so-called universal blood type O blood,It takes great human cost to find the rare blood type establish rare blood type map it?LiuYanChun explain:"Type O blood plasma has A resistance and resistance to B,The whole blood to the patient if lost,Its resistance to A and B resistance may be caused by type A and type B the patient's red blood cell destruction."Same type blood transfusion is not these problems,So in this sense,Each new rare blood type findings mean that a number of potential patients received life support.(finish)
