As a stable genetic marker of human, blood group is expressed in a polymorphic system in the population. Blood group and pathogens mainly produce effects through the interaction between antigens and antibodies. On the one hand, they can promote pathogen colonization, invasion or evasion of host clearance mechanism, and on the other hand, they can make some hosts less susceptible to corresponding pathogens. By exploring the molecular mechanism between the blood group system and pathogenic microorganisms, it can provide a scientific basis for the treatment of human related diseases and the development of vaccines.

OBJECTIVETo investigate the distribution of Colton, Diego, Kell and Yt rare blood groups in Chinese Nanjing Han population, so as to improve the transfusion capability of patients with rare blood group and to further enrich the rare-blood-donor bank.
METHODSA total of 2 015 blood samples from the blood donors were selected randomly to screen the presence of K⁺ and Kp(c+) (Kell), Yt(b+) (Yt), Co(b+) (Colton), Di(a+b+) and Di(a+b-) (Digeo) antigen allele by using PCR and multiplex PCR.
RESULTSOut of 2005 samples, 1 case with K⁺ gene, 8 cases with Yt(b+) gene and 100 cases with Di(a+b+) gene, 2 cases with Di(a+b-) were identified, while no Kp(c+) and Co(b+) were detected.
CONCLUSIONThe frequencies of K⁺, Yt(b+) and Di(a+), Di(b+) are 0.0003, 0.0013 and 0.0258, 0.9742, respectively. They are very rare blood groups in Chinese Nanjing Han population.

OBJECTIVETo screen rare blood groups Fy(a-), s-, k-, Di(b-) and Js(b-) in an ethnic Zhuang population.
METHODSSequence-specific primers were designed based on single nucleotide polymorphism (SNP) sites of blood group antigens Fy(b) and s. A specific multiplex PCR system I was established. Multiplex PCR system II was applied to detect alleles antigens Di(b), k, Js(b)1910 and Js(b) 2019 at the same time. The two systems was were used to screen for rare blood group antigens in 4490 randomly selected healthy donors of Guangxi Zhuang ethnic origin.
RESULTSWe successfully made the multiplex PCR system I. We detected the rare blood group antigens using the two PCR system. There are five Fy(a-), three s(-), two Di(b-) in 4490 Guangxi zhuang random samples. The multiplex PCR system I has achieved good accuracy and stability. With multiplex PCR systems I and II, 4490 samples were screened. Five Fy(a-), three s(-) and two Di(b-) samples were discovered.
CONCLUSIONMultiplex PCR is an effective methods, which can be used for high throughput screening of rare blood groups. The rare blood types of Guangxi Zhuang ethnic origin obtained through the screening can provide valuable information for compatible blood transfusion. Through screening we obtained precious rare blood type materials which can be used to improve the capability of compatible infusion and reduce the transfusion reactions.

BACKGROUNDMolecular testing is more precise compared to serology and has been widely used in genotyping blood group antigens. Single nucleotide polymorphisms (SNPs) of blood group antigens can be determined by the polymerase chain reaction with sequence specific priming (PCR-SSP) assay. Commercial high-throughput platforms can be expensive and are not approved in China. The genotype frequencies of Kidd, Kell, Duffy, Scianna, and RhCE blood group antigens in Jiangsu province were unknown. The aim of this study is sought to detect the genotype frequencies of Kidd, Kell, Duffy, Scianna, and RhCE antigens in Jiangsu Chinese Han using molecular methods with laboratory developed tests.
METHODSDNA was extracted from EDTA-anticoagulated blood samples of 146 voluntary blood donors collected randomly within one month. Standard serologic assay for red blood cell antigens were also performed except the Scianna blood group antigens. PCR-SSP was designed to work under one PCR program to identify the following SNPs: JK1/JK2, KEL1/KEL2, FYA/FYB, SC1/SC2, C/c and E/e.
RESULTSSerologic antigen results were identical to the phenotypes that were predicted from genotyping results. The allele frequencies for Jk*01 and Jk*02 were 0.51 and 0.49, respectively; for Fy*A and Fy*B 0.94 and 0.06; for RHCE*C and RHCE*c 0.68 and 0.32; and for RHCE*E and RHCE*e 0.28 and 0.72. Among 146 blood donors, all were KEL*02/KEL*02 and SC*01/SC*01, indicating allele frequencies for KEL*02 and SC*01 close to 1.00.
CONCLUSIONSThe use of PCR-SSP working under the same condition for testing multiple antigens at the same time is practical. This approach can be effective and cost-efficient for small-scale laboratories and in developing counties. These molecular tests can be also used for identifying rare blood types.

OBJECTIVEA multiplex PCR system for screening rare blood group antigens K and Yt(b) was constructed to study the distribution of the two blood groups in a Uygur population in Xinjiang, China.
METHODSSequence-specific primers (SSP) were designed based on single nucleotide polymorphism sites of KEL and ACHE alleles encoding the two blood group antigens. The system was designed for simultaneously detecting the two antigens by optimizing the PCR reaction. Three hundred and sixty-two randomly selected healthy individuals were screened. Products of PCR were further analyzed for heterozygosity.
RESULTSThe system was set up successfully. No KK sample was identified and 9 K+ k+ , 41 Yt (a+ b+ ), 4 Yt (a- b+ ) were found among the 362 samples.
CONCLUSIONThe established PCR-SSP based multiple PCR system is efficient to screen the rare blood group antigens K and Yt(b). The information of rare blood donors obtained from the screening can be used to improve the capability of compatible transfusion.

The H(-) (H system), GPA(-) and s(-) (MNS), Rhnull, Rhmod, D--, CCDEE, CCdEE (variations of Rh), GPC(-) (Gerbich), i(+) (I), Lu(b-) (Lutheran), Js(b-) and k(-) (Kell), Fy(a-) (Duffy), Ok(a-) (Ok), Di(b-) (Diego) phenotypes were screened by serological or molecular methods. Jk (a-b-) phenotype was detected by urea hemolytic test. The results showed that one Di (a+b-) individual was found in 1618 blood donors, three Fy (a-b+) individuals in 1007 donors and one CCdEE individual in 633 Rh negative donors. No Jk (a-b-), H(-), GPA(-), s(-), GPC(-), i(+) (adult), Lu(b-), k(-), Js(b-), Lu(b-) and Ok(a-) phenotypes were found in this large scale survey. It is concluded that Di (a+b-), Fy (a-b+), CCdEE phenotypes are confirmed in the blood donors and this study provides the distribution data of erythrocyte rare blood group in Zhejiang Han population.

The purpose of this study was to investigate the distribution of 10 rare red blood groups in Chinese Nanjing population, so as to provide compatible rare blood to patients and to create a donor data bank. Jk (a-b-) (Kidd) phenotypes were detected by urea, while H-(H), GPA-(MNS), GPC-(Gerbich), i+ (Ii) and Lub-(Lutheran) phenotypes were detected by monoclonal, polyclonal antibodies with U type 96 well microplate technology. The screening of Jsb- and k-(Kell), Fya-(Duffy), Ok-(Ok), s-(MNS) and Dib-(Digeo) phenotypes were performed by polymerase chain reaction. The results showed that 2 Jk (a-b-) out of 40337 donation samples and 3 Fy (a-b+) out of 1782 donation samples were found, while no other rare blood phenotypes (H-, GPA-, GPC-, Lub-, Ok-, s-, Jsb-, k-, Dib- and i+) were detected. It is concluded that the frequencies of Jk (a-b-) and Fya(a-b+) are 0.0049% and 0.168% respectively. No more rare blood phenotype was found in this screening.
