RESUMO
Objective To retrospectively analyse the irregular antibodies of the local blood donors ,in order to find the rules ,To ensure the safety and effectiveness of clinical blood transfusion .Methods Collected 169 860 blood donors specimens with the spe‐cific antigen of red blood cells in Shenzhen area from February 2011 to December 2012 ,through Brine method for detection of irreg‐ular antibodies ,positive samples would be identified the specificity of antibodies in blood typing department .Results 169 860 healthy blood donors of irregular antibodies were positive in 36 cases(0 .021% ) ,with 12 cases anti‐M ,4 cases anti‐D ,1 case anti‐P1 ,2 cases anti‐A1 ,1 case of cold antibody ,anti‐M with other irregular antibody in 1 cases ;Male irregular antibody positive rate was 0 .013% (15/118 723) ,female irregular antibody positive rate was 0 .041% (21/51 137) .Conclusion The positive rate of irregular antibody in female blood donors is higher than male blood donors ,and the positive rate of irregular antibody of blood donors is low in this area ,which need to be combined with other irregular antibody detection method to improve the detection rate and ensure the safety and effective of blood transfusion .
RESUMO
Objective To investigate the relationship between platelet maximum aggregation rate(MAR),platelet thrombocyt-ocrit(PCT),platelet count(PLT),platelet distribution width(PDW)and mean platelet volume(MPV)with the course of acute cere-bral infarction(ACI)to provide the basis for its clinical early diagnosis and treatment.Methods 107 patients with ACI in our hospi-tal were selected and divided into the great infarction group(infarction size >10 cm3 ),middle infarction group(infarction size 4-10 cm3 )and small infarction group(infarction size0.05 );PCT,PDW and MPV in the great and middle infarction groups were increased(P 0.05).Conclusion The change of the platelet aggregation rate,number and volume is closely related with the occurrence and development of ACI,monitoring their change has important clinical significance to prevention and treat ACI.
RESUMO
Objective To explore the changes of plasma fibrinogen ,plasminogen and D-dimmer before and after thrombolytic therapy in patients with acute myocardial infarction (AMI) ,to provide the evidence for treatment and prognosis AMI .Methods 93 cases of patients with AMI were divided into twe groups ,reperfusion group of 77 cases ,obstract group of 16 cases .At the same pe-riod ,30 cases myocardial infarction of patients with non thrombolytic therapy were selected as control group .The levels of plasma Fib ,Plg and D-dimer in each group were detected at different times .Results The levels of Fib and D-D in AMI patients were higher than those in the control group before thrombolysis therapy (P<0 .05) .Compared with before thrombolysis therapy ,the Fib and Plg levels of AMI patients were decreased significantly after thrombolytic therapy 6 h(P<0 .01) ,and returned to the normal level after 48 h .The D-dimmer level of AMI patients was increased significantly after thrombolytic therapy 6 h(P<0 .01) ,and returned to the normal level after 7 d .After thrombolytic therapy 6 h ,the levels of Fib and Plg of reperfusion group were decreased signifi-cantly(P<0 .05) ,the level of D-dimmer was increased significantly (P<0 .05) .Conclusion The levels of plasma fibrinogen ,plas-minogen and D-dimmer have important reference value for monitor the thrombolytic therapy effect in patients with AMI .
