稀有血型

结论摸清了潍坊地区RhD阴性献血者红细胞血型分布特点，建立了稀有血型管理档案，为Rh阴性患者储备了宝贵的血液。

Conclusions Found out the Red blood distribution character of RhD negative donors in Weifang district , set up the administrative records of rare blood group , and stored the valuable blood to RhD negative patients .

方法：用3种具有不同端基的mPEG修饰红细胞，观察其对红细胞表面4种稀有血型抗原的修饰效果及对红细胞结构、功能和存活期的影响。

Methods : Three kinds of mPEG derivatives were used to modify human RBCs . The camouflage effects of mPEG on four kinds of rare blood group antigen located on RBC surface and the influence of mPEG modification on cell structure and function were observed .

不包括在ABO血型系统的血型被认为是稀有血型，稀有血型的人会发现当他们需要输血的时候，要找到一个适配的血型非常困难。在稀有血型之中，还有极其稀有的血型。比如说，Rhnull血型。

Blood that doesn 't fall into the ABO system is considered rare , and those who have such blood may find it challenging to locate a compatible donor when in need of a transfusion.Still , there 's rare blood , and then there 's really rare blood .

综上所述，本研究说明，mPEG-BTC修饰红细胞，能有效遮蔽红细胞的稀有血型抗原，不影响红细胞的结构功能，是制备通用型血的一条有效途径。

The mPEG-BTC could camouflage the rare blood group antigens on RBC surface efficiently and had no influence on structure and function of modified RBCs . It will provide a useful strategy for preparation of universal donor blood .
