This study aimed to assess the specificity of auricular acupoints in responding to changes of qi and blood which, in traditional Chinese medicine, are considered as the fundamental substances in the human body for sustaining normal vital activity.

In this study, to analyze the influence of the brightness value of the supranasal point and the apex nasi on their dominant wavelength and excitation purity according to the spectrocolorimetry data of the supranasal point and the apex nasi in healthy adults that were collected based on optical spectrum colorimetry.

In this study, optical data on color of tongue tips were collected by using a visible reflection spectrum system. Quantitative method of tongue inspection and classification of tongue states including pale, pale red, red and crimson manifestations were investigated.

Using the data from normal tongue and lip colors of normal people which were collected by the visible reflection spectrum, we analyzed the colorimetric parameters of tongue and lip colors.

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.

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.

BACKGROUND:Buprenorphine transdermal patches have the characteristics of stable blood concentration, long duration of analgesia, respiratory depression and less side effects, which have been widely used in the treatment of moderate to severe chronic pain. OBJECTIVE:To observe the clinical outcome of preoperative analgesia by buprenorphine transdermal patches for pain management after posterior lumbar surgery. METHODS: Eighty patients scheduled for posterior lumbar decompression and interbody fusion under general anesthesia were enroled, 45 males and 35 females, aged 42-71 years, who were randomly divided into two groups, 40 cases in each group: experimental group and control group. In the experimental group, buprenorphine transdermal patches were given 2 days prior to the internal fixation, and intravenous injection of parecoxib was given for postoperative pain management. In the control group, placebo patches were given prior to the internal fixation, and self-control vein analgesia pump and intravenous injection of parecoxib were given for postoperative pain management. Visual analog scale scores were recorded at 6, 12, 24, 48 hours after surgery as wel as doses of tramadol hydrochloride and pethidine hydrochloride used postoperatively and side effects. The patient's satisfaction, drainage and blood count, erythrocyte sedimentation rate, C-reactive protein level at 48 hours postoperatively were detected and recorded in the two groups. RESULTS AND CONCLUSION:There was no significant difference between these two groups in visual analog scale scores, dosage of tramadol hydrochloride and pethidine hydrochloride used postoperatively, postoperative drainage amount, leukocyte count, erythrocyte sedimentation rate and C-reactive protein level (P > 0.05). Postoperative incidence of nausea, vomiting and delirium was lower in the experimental group than the control group (P < 0.05), but the patient's satisfaction in the experimental group was better than that in the control group (P< 0.05). These findings indicate that buprenorphine transdermal patches have better preemptive analgesia for posterior lumbar surgery, with less adverse effects and better patient's satisfaction.

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.

OBJECTIVEDanshen, 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.

METHODIn 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.

RESULTThe 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.

CONCLUSIONDanshen 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.
