Objective To investigate the relationship between positron emission tomography (PET) and cognitive dsyfunction in patients with multiple sclerosis (MS). Methods 2 cases of MS were test with the Wechsler Intelligence Scale (WIS) or mini-mental state examination(MMSE), brain MRI and PET,then the results were analysed. Results The MMSE score of the case 1 was 19, which was lower than normal. The WIS score of the case 2 was normal. The PET of 2 patients showed that there were many hypo-metablism areas in cortex or subcortex.In addition,some cortical hypo-metablism areas of PET were not correspondingly found lesions in cortex or subcortex by MRI. Conclusions There are many hypo-metablism areas in cortex or subcortex in MS patients. The hypometablism areas may be correlated with the cognitive dysfunction of MS.

0.05). Conclusions The effect of rocuronium can be potentiated by nitroglycerin-induced deliberate hypotension, while time for maximum depression is prolonged.However, the time course of recovery of rocuronium can not be affected markedly.

Objective To investigate the alternation of left ventricular systolic function in patients underwent transcatheter aortic valve implantation operation(TAVI) by three-dimensional speckle tracking technology (3D-STI).Methods Totally 20 patients with severe aortic stenosis were enrolled.All the subjects underwent successful TAVI operation.The real-time 3D full volume datasets on apical four-chamber view were acquired on before,7 days and 1 month after TAVI.Left ventricular global longitudinal strain(GLS),regional peak systolic longitudinal strain(LS),regional peak systolic circumferential strain(CS) and regional peak systolic radial strain(RS),were analysed using off-line TomTec software,the differences among the three groups were compared.Results Compared with the preoperation,aortic valve blood flow velocity (AV),mean aortic valve pressure gradient(mPAG) of 7 days after operation decreased significantly.Threedimensional left ventricular ejecation fraction(3D-LVEF) among the patients whose 3D-LVEF under 50％had a remarkable increase and whose 3D-LVEF exceed 50％ before operation had no significant change,while 1 month after operation the 3D-LVEF had a significant improvement compared with the preoperational data regardless of 3D-LVEF under 50％ or not.The GLS and LS of all segments of 7 days after TAVI were higher than pre-operation(all P ＜0.05),and it had a further improvement 1 month after TAVI.Conclusions LV systolic function had improvement early after TAVI.3D-STI is a new,convenient way to detect the global and regional left ventricular systolic function of TAVI patients.
