Objective To compare the features of magnetic resonance imaging (MRI) and electroencephalogram (EEG) to differentiate Alzheimer's disease (AD) and vascular dementia (VD). Methods It was analyzed of the MRI and EEG from 39 patients with AD and 56 patients with VD, to compare the proportion of cerebral atrophy, hippocampal atrophy and leukoaraiosis in MRI, and the proportion of the moderate to severe disorder of EEG and the power spectrum. Results The proportion of cerebral atrophy and hippocampal atrophy was more and leukoaraiosis was less in the AD group than those in the VD group. The proportion of the moderate to severe disorder of EEG increased in AD group, and the ratio of (θ+δ)/(α+β) of whole brain was more in the AD group than in the VD group (P<0.05). Conclusion It is more likely to be AD in dementia patients with atrophy without leukoaraiosis and cerebral ischemic lesions, especially for those with severe abnormal EEG.

Aim To investigate the protective effect of non-mitogenic human acidic fibroblast growth factor (nm-haFGF) on cerebral ischemia-reperfusion injury in mice. Methods Cerebral ischemia-reperfusion model was made by ligating bilateral carotid for 20 minutes in mice. These mice were randomly divided into model group( iv NS), two doses of nm-haFGF (iv 25、50 ?g?kg-1) groups, rhaFGF group(iv 50 ?g?kg-1) and sham- operated group. Step down test and Y-type electric maze were used to examine the effect of nm-haFGF on learning and memory of mice, then Even′s Blue(EB) level and NO level in brain of these mice were measured. Results The nm-haFGF significantly decreased numbers of errors of mice in 5 min in step down test and in Y-type electric maze test; EB and NO levels in brain of these mice were lower than those of model group respectively. Conclusion The nm-haFGF can protect cerebral ischemia-reperfusion injury in mice.

OBJECTIVE: To better understand the pre-operation evaluation of donor kidneys from extended criteria donation after cardiac death and to improve the management during and after renal transplantation. METHODS: Both of the donor kidneys were from the donor who underwent liver transplantation 5 years ago in the Center of Organ Transplantation of Central South University. The donor was admitted because of liver function deterioration which led to hepatic coma, brain death, hepatorenal syndrome and cardiac death sequentially. Deceased donor score (DDS) and "zero point" kidney biopsy were applied to evaluate the donor kidney. After thorough examination of the donor and the renal function, renal transplantation was performed on 2 recipients. RESULTS: The recipients were followed up by 6 months, both of whom developed pulmonary infection and relieved after treatments. The kidney grafts functioned well and no surgical complication and no acute rejection occurred during the follow-up. CONCLUSION Proper evaluation of the donor organs ensures the safety of renal transplantation with kidneys from cardiac death donors who underwent liver transplantation, which is an important way to increase the number of organs for transplantation, yet the long-term effects need further observation.
