Objective To study the imaging of central pentine myelinolysis (CPM) and extrapontine myelinolysis(EPM) after liver transplantation and value of DWI. Methods Eight patients after liver transplantation with CPM and EPM were included in our study, 4 cases of female and 4 cases of male.MR examinations were performed on Philips 1.5 T MRI system. The sequences included SE T1 WI, FSE T2Wl,axial SE-EPI DWI,TR/TE 6225/118.7 ms, ETL 128, FLIP 90°, thickness 5 nun, matrix 128 ×128,b=1000 mm2/s. Results Four of B type hepatitis and cirrhosis and 1 case combined with hepatic carcinoma, 1 of C type hepatitis with cirrhosis from schistosome,2 of C type hepatitis and cirrhosis, 1 of cholangiogenic cirrhosis. MR demonstrated prolongation of T1 and T2 with a shape of butterfly, round or quadrangle on the brain stem sparing of the corticospinal tract and peripontine tissue. The lesion manifested high signal intensity both on DWI and ADC map indicating T2 effect and vasogenic edema. Follow up MR in 2 cases 2 months later showed more prolongation of T1 and T2 than the first time and the lesion manifested iso-intensity signal on DWI and high signal intensity on ADC map suggesting increased diffusivity. Abnormal signal intensities were detected on the bilateral caudate head, globus pallidus, putamen and cerebral cortex in 3 cases. Conclusion CPM should be considered when prolongation of T1 and T2 with a shape of butterfly, round or quadrangle on the brain stem, sparing of the corticospinal tract and peripontine tissue was detected for patients of pest-transplantation. When combined with other area abnormality, EPM and CPM should be considered. DWI can early and sensitively show the lesion.

ObjectiveTo investigate the effects of early stage Alzheimer's disease(AD)on white matter(WM)integrity using diffusion tensor imaging(DTI)and its relationship with cognitive function decline.MethodsDTI was performed in 32 subjects,including 14 early AD patients and 18 elder controls(ON)with a 1.5 T MR scanner. Fractional anisotropy(FA)and mean diffusivity(-D)values were computed and compared for 9 regions of interest(ROI).Eight standard neuropsychological tests were performed and compared between AD and ON to evaluate basic cognitive capacities of AD.Correlation analysis was applied between FA,(-D) values and scores of neuropsychological tests for all subjects.ResultsFA significantly decreased in splenium of the corpus callosum and the posterior parietal-temporal region(S2),and D significantly increased in the splenium in AD patients(P<0.05).AD patients showed lower scores compared with ON in all neuropsychological tests(P<0.05).FA of the splenium and S2 positively correlated with several tests scores,while (-D) of multiple ROIs negatively correlated with several tests scores (P<0.05).ConclusionsIn the early stage of AD,neuropathology has effect not only on cognitive function,but also on white matter structure,and they have strong relationship.AD patients show white matter changes in specific regions,which reflect loss in cortico-cortical connections.

BACKGROUND:Currently, bioactive glass and polylactic acid have been used in clinical dentistry and plastic surgery; however, their therapeutic outcomes are not satisfactory, because the material properties have some limitations. OBJECTIVE:To explore the cytocompatibility of oxygen plasma-treated polylactic acid and bioactive glass guided bone regeneration membrane. METHODS:Bioactive glass and polylactic acid were used as the basic materials to prepare polylactic acid membrane, polylactic acid and bioactive glass composite membrane and oxygen plasme-treated polylactic acid and bioactive glass composite membrane, al of which were used to culture MG63 cels. Cel adhesion rate, cel proliferation rate and alkaline phosphatase activity of MG63 cels on these three kinds of membranes were observed. RESULTS AND CONCLUSION: With the growth of time, in these three groups of membranes, the cel adhesion rate and cel proliferation rate were al significantly increased. Alkaline phosphatase activity showed a decreasing trend after the first increase, and reached its peak at the 7thday of culture. The cel adhesion rate and cel proliferation rate in oxygen plasma-treated polylactic acid and bioactive glass group were significantly higher than those in the other two groups, while the cel adhesion and proliferation rates in polylactic acid and polylactic acid and bioactive glass groups were similar. At the 3rd day of culture, the alkaline phosphatase activity in the polylactic acid and bioactive glass group and oxygen plasma-treated polylactic acid and bioactive glass group was significantly higher than that in the polylactic acid group. At the 7th and 14th days, there was no significant difference in the alkaline phosphatase activity among these three groups. These results show that oxygen plasma-treated polylactic acid and bioactive glass composite membrane has good biocompatibility, which can better promote cel adhesion, proliferation and matrix secretion from osteogenic cels.
