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.

Objective:To construct the Helicobacter pylori infected C57BL/6 mice model to observe the activation of NOD1/NF-κB signaling pathways in the gastric tissues,and study its roles in inflammatory response during Hp infection.Methods:6-8 week-old C57BL/6 mice were randomly divided into two groups,the Hp infection group and the control group,and mice were given by gavage every 48 h for five times with Hp or PBS,respectively.All the animals were sacrificed at different time point and the gastric tissue were stained with hematoxylin-eosin( HE);The mRNA expression of NOD1 and RIP2 in gastric tissues were examined by RT-PCR;Levels of IFN-βand IP-10 in mice serum were assessed by ELISA;Nuclear translocation of p65 in gastric tissue was detected by Western blot.Results:Hp infection elicits an inflammatory cell response,glands in gastric tissue were reduced or atrophic,as compared with that in the control group.The levels of IP-10 and IFN-βincreased in the model group, and peaked at 16 weeks after Hp infection.Hp infection increased the mRNA expression of NOD1 and the p65 content in nuclear between 24-120 h(P<0.05),and the highest level at 48 h,subsequently the expression levels were began to decrease.The mRNA expression level of RIP2 was up-regulated after Hp was administrated, peaked at 48 h and declined after 72 h.However, the expression levels would rise again at 120 h.Conclusion: Hp infection can activate the NOD1/NF-κB signaling pathways and induce the production of IFN-βand IP-10 in gastrics of mice.

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.
