RESUMO
Objective To investigate the diagnostic values of multi-slices spiral computed tomography (MSCT) and magnetic resonance imaging (MRI) for Castleman disease.Methods Six Castleman disease patients confirmed pathologically in some hospital from January 2011 to December 2016 had their clinical data and imaging findings by MSCT and MRI analyzed retrospectively,of whom,all the ones underwent examinations by noncontrast and contrast-enhanced CT scans,1 patient went through MRI examination.Results All the patients had the lesions being solitary and focal,of whom,3 female patients aging from 44 to 52 years old had thoracic lesions and the remained 3 male patients aging from 27 to 53 years old had abdominal lesions.MSCT showed round or oval soft tissue masses with homogeneous density and clear boundary in the 6 patients.Contrast-enhanced scan found significantly homogeneous enhancement similar to the adjacent artery in arterial phase and persistent enhancement in delayed phase,and there were feeding artery and draining vein in adjacent area.Volume rendering and maximul intensity projection displayed the feeding artery and draining vein clearly.Conclusion MSCT and MRI contribute to evaluating the blood supply and adjacent anatomy of Castleman disease patient,and thus can provide references for its clinical diagnosis.

RESUMO
OBJECTIVE@#To observe pathological changes and apoptosis in rats myocardial cells after Macleaya cordata total alkaloids poisoning, and to provide some references for Macleaya cordata total alkaloids poisoning detection.@*METHODS@#An experimental model of Macleaya cordata total alkaloids poisoning was established, and the technology of TUNEL staining was used.The results were analyzed by computer image analysis competitive system.@*RESULTS@#Quantities of apoptosis in myocardial cells in poisoning groups were much more than those in the control groups at different tages (P<0.01). In addition the quantities of apoptosis were different after different poisoning duration.@*CONCLUSION@#Although clinical symptoms was not obvious and could not be detected by poison analysis. Pathological changes induced by Macleaya cordata total alkaloids could be found through the apoptosis detection.
