Objective To investigate the evolution of diffusion indices in the pyramidal tract with Wallerian degeneration(WD)due to cerebral infarction using diffusion tensor imaging(DTI),and to study the relationship between early changes of diffusion indices and motor deficit.Methods Fifteen patients (13 males and 2 females)with acute cerebral infarction(within 7 days)were recruited from the Neurology Department from Mar 2006 to Jan 2007.A11 patients were assessed with DTI.National Institutes of Health Stroke Scale(NIHSS),Bathel Index(BI),modified Rankin Scale(mRS)and Motricity Index(MI)within 7 days from onset,and at the second week.DTI was performed with SIEMENS Trio 3.0 T MR scanner.The placement of region of interest(ROI),measurement of diffusion indices were performed by DTI Studio software.The mean diffusivity(MD),the fractional anisotropy(FA),the first eigenvalue (λ1),the second eigenvalue(λ2),and the third eigenvalue(λ3)were computed.Results At the second week.NIHSS was 6.93±3.39.BI 45.33±26.01,mRS 4.33±0.90.and MI 69.47± 60.71.At the second week from onset.MD of the pyramidal tract at the levels of the middle slice of pons and the superior slice of medulla oblongata showed no significant differences between both the two sides at second week from onset. Other ROI showed significant differences between both sides.MD.FA and λ1 of affected side were lower than the unaffected side.λ2 and λ3 of the affected side were higher than the unaffected side.Positive correlations were found between FA and BI(r=0.530,P=0.042),FA and MI(r=0.543,P=0.036)at the second week.Negative correlations were found between FA and NIHSS(r=-0.613,P=0.015)at the second week.Conclusions DTI can detect the changes in the pyramidal tract due to WD within 7-14 days after ischemic stroke.including a decrease of the fractional anisotropy.the first eigenvalue and increased the second and the third eigenvalues.The fractional anisotropy of the second week from onset is related to the outcome of the motor function.

Objective To study CD64 expression in neutrophilic granulocyte and its clinical effect in neonatal infection disease. Methods CD64 was detected among 59 neonatal patients(septicemia group 34 patients, local infection group 25 patients)hospitalized in our neonatal department diagnosed as neonatal infection disease in 48 h after hospitalized,2 weeks after therapy, then the results were compared with 27 patients as non - infection disease during the same period. Results CD64 in septicemia group was (6156. 21?3643. 32) molecula per cell,in local infection group was (2176.19 ? 946. 32)molecula per cell, in non- infection group was (2176. 19 ? 946. 32) molecula per cell.There were significant differences among three groups (all P0.05). Conclusions CD64 expression increases in bacterium infection disease. It is more obvious in widespread infection desease.and it can be the mark in early diagnosis of neonatal infection disease.

OBJECTIVETo explore the scavenging action of tenuigenin (TEN) on intracerebral amyloid β protein (Aβ) aggregation and the abnormal phosphorylated tau protein and its mechanism in Alzheimer's disease (AD) rats' brain.

METHODSAβ1-40 was injected into the right CA1 region hippocampus to establish the AD model. Successfully modeled rats were divided into the model group, the low, middle, high TEN group. Rats were administered with TEN (18.5, 37.0, 74.0 mg/kg) by gastrogavage. Besides, a sham-operation group was set up. Expression levels of Aβ1-40 and Tau p-Ser262 were detected by immunohistochemistry. Expression levels of ubiquitin (Ub) and Ub-protein ligase E3 were measured by Western blotting.The content of 26S proteasome was detected by ELISA.

RESULTSImmunohistochemical results showed that the number of Aβ and Tau p-Ser262 positively reacted neurons significantly increased in model group, when compared with the sham-operation group (P < 0.01). Results of Western blot showed expression levels of ubiquitinated protein were up-regulated and those of Ub-protein ligase E3 were down-regulated in the model group (P < 0.01). ELISA results showed that the content of 26S proteasome significantly decreased in AD rats' brain (P < 0.01). Compared with the model group, expression levels of Aβ1-40, Tau p-Ser262, and Ub significantly decreased; expression levels of Ub-protein ligase E3 apparently increased; the content of 26S proteasome significantly increased in each TEN treatment group (P < 0.05, P < 0.01). Best effect was shown in 37.0 mg/kg and 74.0 mg/kg TEN groups.

CONCLUSIONSUb proteasome pathway (UPP) participated in the occurrence of AD. TEN could obviously reduce intracere- bral Aβ1-40 accumulation and abnormal tau phosphorylation.
