ObjectiveTo observe the effect of vinpocetine sustained-release capsules on post-stroke depression and recovery of neurological function. MethodsA total of 64 patients with acute post-stroke depression were randomly divided into Vinpocetine sustained-release capsules group( 34 cases) and control group(30 cases). Conventional therapy was given to both groups. To the treatment group, vinpocetine sustained-release capsules was given at the same time. Depression status was assessed with Hamilton Rating Depression Scale(HAMD). Meanwhile ,Mimi-Mental State Examination( MMSE), National Institutes of Health Stroke Scale(NIHSS) and Activities of Daily Living(ADL)were given in to both groups. ResultsAfter 6 to 12 weeks' therapy, the total score of HAMD, NIHSS and ADL of Vinpoeetine group were significantly lower than the control group ( all P ＜ 0.05 ), MMSE score increased significantly ( P ＜ 0.05 ) in Vinpocetine group. The curative rate and effective rate of Vinpocetine group were 38％ and 91％. It was significantly higher than the 20％ and 73％ of the control group ( all P ＜ 0.05 ). ConclusionVinpocetine sustainedrelease capsules was effective to treat post-stroke depression. It could improve the emotional state of patients and promote the recovery of neurological function.

Objective To observe the effect of vinpocetine on monoamine transmitters in cerebral of poststroke depression (PSD)rats and to investigate the mechanism of pharmacotherapeutics on PSD. Methods Rats were divided randomly into the sham-operated group,the normal saline group,the low dose of vinpocetine group and the high dose of vinpocetine group. Giving the left middle cerebral artery occlusion, the PSD rat model was established by unexpected chronic mild stress. When the PSD rat model was established, vinpocetine group was given vinpocetine(5mg/kg, 10mg/kg) and the normal saline group was given normal saline. Then the ethological score of depression was evaluated on 14 and 28 days. The monoamine transmitter in the frontal cortex and hippocampus and brainstem were detected by the fluorospectrophotometry. Results On the 28th day after the model establishment,compared with the normal saline group, the ethological score of depression level was decreased obviously. Compared with the normal saline group, vinpocetine could improve the ethological score of depression level of the PSD rat model, and these concentrations of 5-hydoxytrypatarmine ( 5-HT), noradrenalin ( NE ) and dopamine ( DA ) in the frontal cortex, hippocampus and brainstem. The level of NE ( ( 192.4 ± 34.8 ) ng/g, ( 206. 0 ± 41.7 ) ng/g,(91.1 ±23.0) ng/g] ,5-HT( (494. 1 ± 50.7) ng/g, (599.7 ± 39.2) ng/g, (541.7 ± 62.6) ng/g) and DA ( ( 298.6 ± 32.6) ng/g, ( 297.0 ± 38.1 ) ng/g, ( 85.9 ± 24.3 ) ng/g) in the high dose of vinpocetine group were significantly higher than that in the normal saline group ( NE (92.4 ± 17.5 ) ng/g, ( 131.4 ± 34.8 ) ng/g, (49.0 ±13.6)ng/g;5-HT(367.8 ±87.3) ng/g,(498.7 ± 79.6) ng/g, (320.4 ±59.4) ng/g; DA( 106.1 ±23.0)ng/g,(97.0 ±21.7)ng/g, (50.4 ± 13.8 )ng/g)(P ＜ 0.01 ). There were increased obviously by the high dose than the low dose of vinpocetine group. Conclusion Vinpocetine could treat PSD by increasing the level of monoamine transmitters in PSD rats' brain.

Mind map is an effective and intuitive knowledge organization and presentation tool which can help computer teaching commendably. We can use Mind Map to design and organize the whole teaching process, including preparing, designing, guiding, analyzing and reviewing. This way can turns tedious logic of computer teaching into imagery thinking and helps medical students improv-ing their learning effect of computer courses.

Objective To investigate the relationship between the different embolization agent and the spinal cord ischemic injury. Methods Bilateral of intercostal arteries were embolized with gelatin sponge and lipiodol to block the blood supply of spinal cord. To detect the somatosensory evoked potentials(SEPs), 6 canines in both groups of gelatin sponge and lipiodol were treated by bilateral intercostal arteries embolization. The median nerve and fibular nerve were recorded and the ratio of lower extremity to upper extremity SEPs amplitude (LE/UE ratio) were calculated; the results were compared with the pathologic findings and the motor function. Results The baseline, LE/UE, evoked potential amplitude ratios in all dogs before operation ranged from 0.22 to 0.92 with a combined total mean of 0.49?0.07. The SEPs changes at 30 minutes post operation were more obvious than pre operation in gelatin sponge group and lipiodol group with statistic significance. The LE/UE ratio of gelatin sponge group recovered one hour after operation, but this was absent in lipiodol group. So did the latency SEPs changes. Conclusion The SEPs could not be used to evaluate the motor function of spinal cord comprehensively.

Objective To investigate the feasibility and cortex activation of fMRI in the aged volunteers during the performance of visuospatial tasks. Methods Visuospatial tasks were conducted in 11 normal aged volunteers. The fMRI data was postprocessed using SPM99 to reveal the activated cortex.Results The visuospatial tasks were fulfilled satisfactorily in all aged subjects. Cortex around the left intraparietal sulcus, dorsolateral cortex in the left prefrontal lobe and bilateral occipital lobes showed activation. We found a selective enhancement of fMRI signal in the left superior parietal lobule. Conclusion FMRI tasks are feasible in the aged people and the left superior parietal lobule is the specific in the visuospatial information processing.
