Study On Specific Feature Of Acupoints SJ5 With Positron Emission Tomography

Objective:To study Specific Feature of acupoints and non-acupoints with Positron Emission Tomography. We study the cerebral function imaging Feature of acupoints and non-acupoints by analyzing blood stream, metabolism, function index of different encephalic region in this series of Positron Emission Tomography (PET) experiments, in order to explore stroke suffers'Specific Feature of waiguan of metergasis of different encephalic region.Method:Acupuncture stimulation was induced by manipulating acupuncture needle at the acupoint SJ5(waiguan, right arm) of 5 suffers and non-acupoints of 5 suffers in stroke suffers. PET data of scanning the whole brain were established by statistical parametri cmapping (SPM), the picture of functional localization were analyzed by group double sample t-test analysis. We can discriminate specific feature of acupoints and non-acupoints by analyzing blood stream, metabolism, function index of different encephalic region in this series of Positron Emission Tomography (PET) experiments.Results:Stimulation of acupoint SJ5 by right arm acupuncture activated left Superior Frontal Gyrus (BA6),Medial Frontal Gyrus (L),Superior Frontal Gyrus,Precentral Gyrus,Superior Frontal Gyrus,Forward rolandic region,supplementary motor area(8),BA13,BA18, BA19,BA24, BA32 (L), caudate nucleus, limbic lobe(L). In the BA2(R),BA4(R),BA9(R),BA13(R),BA22(R),BA38(R),BA40(R),BA6(R),Cerebellar Tonsil (R),Caudate (R),Right Thalamus, Mammillary Body, that displayed high glucose metabolism, they were concerned with motion,sensation,algesia,ambition. In the Superior Frontal Gyrus (R), Medial Frontal Gyrus (R), Middle Frontal Cyrus (R), Superior Frontal Gyrus(L), Occipital Lobe(L), Declive Parietal Lobe, Frecuneus,Inferior Parietal Lobule,Middle Temporal Gyrus,superior temporal gyrus,Postcentral Gyrus, that displayed degrade glucose metabolism, they were concerned with language,hearing and spatial orientation。Conclusion:By cerebral funtion imaging of patients with stroke, the therapy effects are distinguished between acupointing SJ5 points and non-point. To acupointing SJ5 of patients with ischemic cerebral infarction,there were four effects on glucose metabolism of cerebral funtion. Firstly, glucose metabolism of corresponding encephalic region is promoted and exercise capacity is enhanced, which are related with body movement.Secondly, glucose metabolism of corresponding encephalic region is regulated, which are related with sensation. Thirdly, glucose metabolism of BA22,BA40 is controled, which are related with speech audiometer and semantic representations. Lastly, there were a specificity of association between acupointing SJ5 with activating encephalic region and cerbral infarction damage zone, and the activity of encephalic region is regulated, which is related with movement with stroke,sensory disability,affective disorder.After acupuncture needle at the acupoint SJ5(waiguan, right arm) and non-point, such conclusions are found:upper limb disease including paralysis, pain, numbness, swell, etc, are correlated with the stimulations of sensorimotor encephalic region (BA,6,8),somatic sensation (truncus encephalicus,primary somatosensory cortex BA2, spatial orientation and balance BA7,39,40,cerebellum); five senses disease including eyes and ears problems are correlated with the stimulations of vision audition encephalic region (BA18,BA19,BA22); spirit and sensation disease are correlated with the stimulations of corresponding encephalic region (BA,24,32,28 and hippocampus). The effect of acupoint SJ5 has specific meridian feature was significant different with non-acupoints。...
