RESUMO

OBJECTIVE@#To explore the clinical and pathologic features of angioimmunoblastic T-cell lymphoma(AITL) and provide evidence for diagnosis.@*METHODS@#Eighteen AITL patients (9 males and 9 females aged from 14 to 70 years) were retrospectively analyzed in Xiangya Hospital of Central South University from July 2002 to September 2007.@*RESULTS@#Characteristic features at the presentation of AITL included generalized lymphadenopathy, fever, splenomegaly, and skin rashes with polyclonal hyper-gammaglobulinemia and other hematological abnormalities (such as Coombs-positive hemolytic anemia), which often involved the bone marrow and had well-described histologic features. The positive rate for CXCL13 was 93.3%.@*CONCLUSION@#Repeated lymphadenbiopsy is helpful for AITL diagnosis. Routine histological and immunohistochemical examinations (especially including CXCL13) play significant role in the diagnosis and differential diagnosis of AITL.

RESUMO

Objective To establish a rapid,accurate and sensitive method for the determination of toluene diisocyanate(TDI) in plastic playground.Methods The samples were distilled continuously for 12 hours by acetone at 80-85 ℃ in water bath,and after centrifuged,precipitated and filtered,separated by using GC1490,7% SE-30 column,the contents of TDI in the samples were determined by gas chromatography.The qualitative and quantitative analyses were carried out by the retention time and peak area respectively.Results The linear range of the method was 0.001 30-0.043 80 mmol/L.Regression equation was y=28 612x-29.336,with r=0.999,and the limit of detection was 0.001 30 mmol/L.The rates of recovery ranged 100.8%-103.6%,with RSD of 5.7%.Conclusion The developed method was rapid,accurate,sensitive and is applicable to the determination of TDI inplastic playground.
