RESUMO
Objective To explore the diagnostic value of reticulocyte related parameters in thalassemia and iron deficiency anemia(IDA) .Methods Ret％ ,Ret# ,IRF ,LFR ,MFR ,MFR and Ret-He were detected in 56 cases of IDA (IDA group) ,48 cases of thalassemia (thalassemia group) and 45 healthy individuals undergoing the physical examinations(control group) by adopting the XN-1000 automated blood cells analyzer .Then the results were compared among 3 groups .Results Ret％ ,Ret # ,IRF ,MFR and HFR in the IDA group and thalassemia group were higher than those in the control group ,the differences were statistically significant (P<0 .05);Ret-He and LFR in the IDA group and thalassemia group were lower than those in the control group ,the differences were statistically significant (P< 0 .05) .The Ret-He level had statistically significant difference between the IDA group and thalassemia group (P<0 .05) .LFR％ in the thalassemia group was sig-nificantly decreased compared with the IDA group (P<0 .05) .Conclusion The reticulocyte parameters have the important significance in clinical differentiation diagnosis of thalassemia and IDA .
RESUMO
Objective To detect mycoplasma pneumoniae antibody in children having the upper respiratory tract infection.And then investigate mycoplasma pneumoniae infection status of different season different age children.Methods In 5 403 cases of suspected pneumonia mycoplasma infection of 0 to 14 years old children using the method of passive particle agglutination determination of mycoplasma pneumoniae antibody,and analysis of the statistical results.Results The positive rate was 67.8％ in the groups of children.The rates of infection was biggest during 2 to 3 years old children and 3-4 years old children,14.9％ and 18.4％,respectively.In addition,we found that the highest rate of mycoplasma pneumoniae infection arised from October to January every year of the following year.Conclusion The infection of mycoplasma pneumoniae is on the rise,and children aged 0 to 6 years old are the main population.
