WANG Shu-jun, ZHAO Guang-chao, LUAN Jian-feng, et al
JOURNAL OF CLINICAL TRANSFUSION AND LABORATORY MEDICINE. 2017 (2):  119-122.  DOI: 10.3969/j.issn.1671-2587.2017.02.006
Abstract ( 808 )   PDF(767KB) ( 1772 )  
Objective To explore the optimal centrifugation conditions for preparation of platelet-rich plasma (PRP) from different volume of whole blood.Methods Fifty-four bags of freshly collected whole blood from volunteer donors were divided into 6 groups according to centrifugal steps and centrifugal conditions,including 3 two-step (separation method A,B,and C) and three-step centrifugation groups (separation method D,E,and F),with 3 bags of 200 ml,300 ml,and 400 ml whole blood for each group. The platelet count (PLT) and red blood cell count (RBC) of PRP in each group were determined,then PLT recovery was calculated and compared.Results Compared to three-step centrifugation groups,the PRP prepared in two-step centrifugation group had higher PLT recovery and RBC count. The highest PLT recovery in PRP from 200 ml whole blood was prepared by method A (e.g,850×g for 8 min,then 4 650×g for 6min),300 ml whole blood by method B (e.g,1 000×g for 6 min,then 4 650×g for 6 min),and 400ml whole blood by method C (e.g,1 220×g for 5 min,then 4 650×g for 6 min). The RBC count of PRP in each three-step centrifugation group was decreased significantly (P<0.05). Compared with two-step centrifugation group,the PLT recovery in three-step centrifugation group was slightly decreased.Conclusion Different centrifugation conditions should be used for preparation of PRP from different volumes of whole blood . The two-step centrifugation method is suitable for preparation of fresh PG or platelet gel,while the three-step centrifugation method is appropriate for frozen and lyophilized PRP or platelet gel.

JOURNAL OF CLINICAL TRANSFUSION AND LABORATORY MEDICINE. 2017 (2):  123-125.  DOI: 10.3969/j.issn.1671-2587.2017.02.007
Abstract ( 1562 )   PDF(724KB) ( 1391 )  
Objective To retrospectively investigate the patients for the emergency rescue blood transfusion who presented positive antibodies and to evaluate the effect of "recommended regimens" in clinical transfusion.Methods Inform-ation of the individuals was collected in Handan area from June 2014 to May 2016, and irregular antibodies were screened and patients with positive antibodies for emergency rescue blood transfusion were evaluated for the application effect based on "recommended regimens ".Results Twenty cases of emergency rescue group and 31 cases of blood transfusion showed a total efficiency of 77.4%, following 31 times of transfusion with 126 U red blood cells (4 U on average). Eighty three cases received 137 times of transfusion after specific antibodies were identified,with a total efficiency of 86.9%. No obvious difference was seen between the two groups(χ2=1.78,P>0.05).Conclusion It is relatively safe for the patients with positive irregular antibodies who need emergent blood transfusion to use the same blood type and negative blood cross-matching, or to use O type and negative cross-matching. The present investigation suggests that there is no difference of blood transfusion efficiency between the patients with emergent transfusion and normal transfusion.

Abstract ( 420 )   PDF(734KB) ( 807 )  
Objective By analyzing irregular antibody screening of patients with blood transfusions,we explored its significance in blood transfusion safety and regional clinical guidance.Methods 38 722 patients with blood transfusions were studied from February 2012 to February 2016and among them positive irregular antibodies were screened and specificity was analyzed for safe and effective transfusion. Reasults 278 cases of positive irregular antibodies were found in the patients,which accounted for 0.717% (278/38 722). Among them 83 males with a positive rate of 0.214% (83/38 722),and 195 females with a positive rate of 0.503% (195/38 722)were observed. Female patients had a significantly high positive rate when compared with male patients(P<0.05). The positive incidence of 0.114% (26/22 846)in the patients with history of blood transfusion and pregnancy was lower than that in control (1.587%,252/15 876)(P<0.05).. . Among the 278 patients with irregular antibodies,128 (46.0%) patients presented specific antibodies,including 98 cases of RH (35.3%,98/278),20 cases of MNS patients (7.2%,20/278),and 10 cases of others(3.6%,10/278). 150 (54%,150/278) patients had non-specific antibodies,,68 had cold antibodies (24.5%,68/278),and 82(29.5%,82/278) carried other non-specific antibodies.Conclusion Analysis of the north central area of Guangxi province are similar with the other regions,under the normal conditions.

ZHAO Ling-jun
JOURNAL OF CLINICAL TRANSFUSION AND LABORATORY MEDICINE. 2017 (2):  178-182.  DOI: 10.3969/j.issn.1671-2587.2017.02.025
Abstract ( 599 )   PDF(822KB) ( 964 )  
Objective To analyze a discrepancy in results of forward/reverse ABO blood grouping with molecular analysis and provide knowledge for safe blood transfusion.Methods Column gel testing was used for serological ABO blood grouping. Genomic DNA was extracted from whole blood and PCR-SSP was used for ABO genotyping. PCR was performed to amplify ABO exons 1 to 7 and the amplification products were sequenced directly. The obtained sequences were compared with wild type A101 to identify sequence variation.Results Blood grouping indicated the discrepant results of forward/reverse ABO typing. Forward typing produced blood group O,while reverse typing produced blood group A as only anti-B isoagglutinins were present. A monoclonal anti-AB antibody detection revealed a weak agglutination with patient's RBCs. ABO genotyping with PCR-SSP indicated a heterozygous O1/A type,and further PCR and ABO exons sequencing identified a new 248A>G missense mutation in exon 6,which led to the replacement of Aspartate at position 83 with glycine. PCR-SSP using newly designed 248A>G mutation-specific primer was performed to investigate the frequency of this new mutation among regular blood donors but none turned out to be positive.Conclusion sThis ABO gene 248A>G mutation is associated with the absence of anti-A isoagglutinins and weak A antigen expression.

Objective To investigate the sense of keeping the border area, find the re-entry detective strategy, follow-up detection were used to check the blood donors with false-reactive results in basic-level blood station.Methods during January 2014 to February 2016, 712 cases which reacted in single reagent(including border area)were selected. Based on ELISA test results, specimens were divided into border area group and single-reagent-reactive group. After more than six months of shielding,re-entry specimens were tested by ELISA in double reagent, nucleic acid testing (NAT) and confirmatory test.Results In the first ELISA test, the result were confirmed by NAT(or TPPA) , the difference of the false-reactive rate of HBsAg and anti-TP in the border area group and single-reagent-reactive group was statistically significant, P<0.05.While the difference of anti-HCV false-reactive rate between the two groups has no statistical significance. After more than six months of shielding, the re-entry test showed that, 1 of 213 in the border area group was reactive in NAT, but not confirmed by the confirmatory test, 3 of the 268 in the single-reagent-reactive group were confirmed by NAT and confirmatory test.Conclusion Since NAT was carried out broadly under the present detection mode, if keep on setting border area, it will increase the false-reactive specimens, may result in blood waste.

Abstract ( 1312 )   PDF(714KB) ( 1162 )  
Transfusion related acute lung injury(TRALI),which is defined as the onset of acute lung injury within 6h of transfusion,is the most common cause of transfusion related death worldwide.The two most prevalent pathogenesis of TRALI are antibody mediated and non-antibody mediated. Meanwhile,the two-hit model and threshold model are supported by many animal studies.So the most effective prevention is a restrictive transfusion strategy,and making exclusion policy that exclude high-risk donor with multiparous history can also reduce the incidence of TRALI.In addition,either the clinical department or blood service are discussing if some other strategies such as“patient-tailored transfusion policy”and “pooling of plasma”have value in reducing the incidence of TRALI.
