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.

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 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.

OBJECTIVE:To establish a method for detecting bacterial endotoxins in methylthioninium chloride injection (MCI) quantitatively. METHODS: Kinetic turbidimetric limulus test was applied to detect bacterial endotoxins in MCI quantitatively, and compared with gel-clot method. RESULTS: MCI was un-interfered with the test for bacterial endotoxins at the concentration of 0.125 mg?mL-1; the content of bacterial endotoxins in all samples tested (10 mg?mL-1) were not more than 0.25 EU?mg -1, which were in accordance with the result of gel-clot method. CONCLUSIONS: Kinetic turbidimetric limulus test provides a new way to detect bacterial endotoxins in MCI quantitatively.

OBJECTIVE:To study the absorptive effect of activated carbon and desorptive effect of organic solvent on endotoxin.METHOD:The effect of different pretreatment modes,time,temperature,amount of activated carbon as well as treatment time on the absorptive effect of activated carbon were analyzed using limulus reagent test.Different organic solvents and treatment time were used to study the desorptive effect of organic solvent on endotoxin.RESULTS:Activated carbon was treated by high temperature baking or adding 0.5 mol?L-1 NaOH represented same effect in removing endotoxin.It showed that optimal time for absorption of endotoxin was 12 min and the amount of activated carbon was at 1.5%.The absorptive effect was similar under condition of room temperature and 37 ℃.The best effect of desorption achieved by using 75% alcohol as desorption reagent after 8 minutes of shaking.CONCLUSION:The activated carbon could be used to absorb endotoxin effectively under suitable conditions and organic solvent could be used to desorb endotoxin from activated carbon.

OBJECTIVE: To investigate the effect of detection index of IL-4 and IgE on rapid examination of drug-induced allergic reaction.METHODS: The guinea pigs were injected with drugs intravenously and intraperitoneously,such as normal saline,horse serum,Qingkailing injection,Xiangdan injection,cerebrolysin injection and Chuankezhi injection once a day for 3 days.Then the content of IL-4 and IgE in serum of guinea pigs was recorded at different time points.Allergic reactions of guinea pigs were observed 8 days after intravenous administration,14 days and 21 days after intraperitoneous administration.RESULTS: As compared with normal saline except for Chuankezhi injection,serum level of IL-4 and total IgE were raised obviously before guinea pigs were challenged either in 8 days after intravenous injection of other drugs or in 14 days and 21 days after intraperitoneous injection.Allergic reaction occurred on all those guinea pigs after they were challenged.CONCLUSION: The detection of IL-4 and IgE provides a new way for rapid test of drug-induced allergic reaction.

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.

Sheng's acupuncture manipulation at bone-nearby acupoints is a set of needling manipulation of the chief physician of TCM, SHENG Xie-sun, summarized through his over 50 years clinical experiences and on the basis of Internal Classic. Regarding this manipulation, on the premise of acupoint selection based on syndrome differentiation, the acupoints close to bone are possibly selected and punctured, with the needle tip toward bone edge, and followed by the technique to achieve reducing purpose. Clinically, the significant immediate analgesia can be achieved in pain disorders such as headache and toothache. Professor Sheng thought, corresponding to the location of needle insertion and needling depth, the tissue layers of needle tip passing through should be considered specially. The site of needle insertion should be changeable so as to ensure the needle tip reaching the bone. This manipulation for analgesia provides a certain guide for acupuncture study, especially for the mechanism study on acupuncture analgesia.
