Objective:To define the kinetics of soluble intercellular adhesion molecule 1 in serum levels after cerebral ischemia and their correlation with the clinical outcome, infarct volume as measured on CT scans ,and the relevance of vascular risk factors Methods:The levels of serum sICAM 1 were mesured with enzyme linked immunosorbent assay (ELISA) method in 35 patients with acute cerebral infaration and 20 cases of normal control Results:Serum sICAM 1's concentration in the samples of cerebral infarction on second day (P

Objective To explore the 18F-FDG PET/CT features of sacral insufficiency fracture.Methods 18 F-FDG PET/CT imaging and clinical data of 8 patients with sacral insufficiency fracture were retrospectively analyzed.Results All 8 patients had different degrees of radioactivity uptake in sacra with the maximum standardized uptake value (SUVmax)from 2.7 to 7.2.Four patients had lesions in their left sacra,2 in the bilateral sacral wings and sacral promontories,1 in the bilateral sacral wings,and 1 in the left sacral wing and sacral promontory.There were 8 patients of longitudinal fractures in sacral wings,which of 6 patients involving S1-2 and 2 patients involving S3.Three patients had transverse fractures in sacral promontories,with 2 located at S2 and 1 at S3.The sacral bone density increased in 5 cases,and the density was not changed in 3 cases.Conclusion Sacral insufficiency fracture had specific 18F-FDG PET/CT characteristics.
