ABSTRACT

<p><b>OBJECTIVE</b>Danshen, as a traditional Chinese medicine for promoting blood circulation and removing blood stasis, is widely applied in improving human erythrocyte deformability in clinics. But its direct effect on erythrocyte membranes is still unclear.</p><p><b>METHOD</b>In this essay, the confocal Raman technique was adopted to measure the changes in Raman spectra of human erythrocytes before and after the administration of Danshen injection.</p><p><b>RESULT</b>The results showed slight changes in group conformations corresponding to erythrocyte membranes after the administration of danshen injection. Specifically, 1064, 1126 cm(-1) spectral lines attributed to phospholipid molecule acyl C-C skeleton anti-conformation were obviously weakened, whereas 1091 cm(-1) spectral line attributed to phospholipid molecule acyl C-C skeleton guache conformation notably intensified. Besides, the longitudinal order-parameter in chains (Strans) of phospholipids was reduced significantly.</p><p><b>CONCLUSION</b>Danshen injection can transfer erythrocyte membrane phospholipid molecule acyl C-C skeleton anti-conformation to guache conformation, indicating the increase in liquidity of erythrocyte membrane phospholipids and erythrocytes. Danshen injection's effect in improving erythrocyte membrane structure and function may be the intrinsic mechanism for its pharmacological effect as a traditional Chinese medicine.</p>

ABSTRACT

Objective To investigate the neural representations of long-term digital memory in human brain by functional magnetic resonance imaging (fMRI) technique. Methods 22 right-handed normal volunteers were recruited to participate in a test of long-term digital memory while the fMRI data were recorded. Control tasks were performed for the block-design. SPM 99 was used to analyze the data and to obtain the activated brain regions.Numbers of activated voxels were used to calculate lateralization index (LI). Results When the threshold was set as P<0. 0001 ,using a one-sample t -test,the middle gyrus of the left frontal lobe(t=9.68) and the right cerebellum ( t = 9.85 ) were activated remarkably during the memory task. The subcortical structures including the thalamus (t=6.72) and the caudate (t=6.58) were also obviously activated during the memory task. LI of the numbers of activated voxels was 0.51. Conclusions The subcortical structures and the cerebellum as well as the cerebral cortex are collaborative to contribute to long-term digital memory function in human brain. The results also reveal that the functional areas of long-term digital memory in human brain are localized with the functional lateralization in the left hemisphere.

ABSTRACT

Objective To examine whether the marginal division of the striatum(MrD)is involved in the associative learning and memory function of human brain with the help of functional magnetic resonance imaging(fMRI)technique.Methods Sixteen right-handed normal volunteers participated in a test of paired-word associative learning and memory,while the fMRI data were recorded.Control tasks were performed for the block-design.Statistcs parameter mapping 99 was used to analyze the data and to obtain the activated brain regions.Results When the threshold was set as P<0.005.using a one-sample T-test,the left occipital lobe and the superior and middle gyrus of the left frontal lobe were activated remarkably during the encoding process of the paired-word associative learning and memory task,with the maximum intensity T value being 13.87 and 9.36.respectively.The left MrD was also obviously activated during this stage(T value was 5.46).But during the retrieval process,the left parietal lobe was prominently activated(T value was 8.73).Conclusion The resuhs of this study reveal that the subcortical structures such as MrD as well as the cerebral cortex are involved in the associative learning and memory of paired-word in human brain.

ABSTRACT

@#Objective:To probe the effects of the electroacupuncture on vascular dementia and its P300.Methods:60 patients suffering from vascular dementia were randomly divided into two groups,the electroacupuncture group(30 cases) and the medicine group(dihydroergotoxine,DHET,30 cases).Changes in scoring value of HDS-R(Hasegawa Dementia Scale),FAQ(Functional Activity Questionaire),ADL,injure of nerve function,main symptoms and P300 were observed before and after treatment.The course was 42 days.Results:The results was that effective rate was 60% in electroacupuncture group and 23.33% in medicine group(P<0.01).All the above indices were improved in electroacupuncture group,better than those of medicine group(P<0.05~0.01).Conclusion:It suggests that the electroacupuncture therapy can promote the VD patients in intelligence,functional activity,ability of daily living and quality of life.
