This study seeks to discuss the light wave transport characteristics variation along the pericardium Meridian under different pressures. We selected 36 healthy students at the school for this study, tied up the desktop blood pressure cuff onto subjects'right proximal arms, fixed the detection probe immovably on the Neiguan [PC6] acupoint and the reference point which was 1cm off the PC6, and collected the light signal along the meridian and non-meridian when the laser irradiate Jianshi[PC5], Ximen[PC4] and the corresponding reference points respectively under pressure of 0, 100, 130 and 160. The differences in optical transport properties between meridian and nonmeridian were significant: under the same pressures [0s, 100s,130s, and 160mmHg], the relative attenuation rate of optical signal at the same distance between meridian and non-meridian were significant[p<0.001], the optical signal attenuates slower when it transported along meridians; however, there is no significant difference for the relative attenuation rate of optical signal along meridian or non-meridian under different pressures[p>0.05]. Under four different pressure situations, the optical signal at acupoint[PC5] and non-acupoint[NP] along the meridian were significantly different with the corresponding reference points along the non-meridian[P<0.001]; the optical signal on the meridian is stronger than the non-meridian one; the optical signals are strikingly different at acupoints, non-acupoints, and reference points between and 100, 130, and 160mmHg pressures [P

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.
