Comparative study of the specificities of needling acupoints DU20, DU26 and HT7 in intervening vascular dementia in different areas in the brain on the basis of scale assessment and cerebral functional imaging / 中国结合医学杂志

<p><b>OBJECTIVE</b>Using methods of clinical scale assessment and cerebral functional imaging to compare the relative specificity of needling acupoints Baihui (DU20), Shuigou (DU26) and Shenmen (HT7) in intervening vascular dementia (VD) in different areas in the brain.</p><p><b>METHODS</b>Fifty patients with VD were randomized into 5 groups. Needling on conventionally used acupoints of hand and foot three Yang-meridians aiming at hemiplegia was applied to the patients in Group A, and needling on DU20 to Group B, on DU26 to Group C, on HT7 to Group D and on all the three to Group E was applied additionally. Assessments of Mini Mental State Examination (MMSE), Activities of Daily Living (ADL) and Family Attitude Questionnaire (FAQ) were made. And the positron emission computerized tomography (PET) and single photon emission computerized tomography (SPECT) examinations were conducted in 5 selected patients from each group before and after treatment.</p><p><b>RESULTS</b>Needling on conventional acupoints plus DU20 could effect the inner temporal system, thalamencephalon system and prefrontal cortical system to improve memory and executive capacity of VD patients; conventional acupoints plus DU26 could effect more to the prefrontal cortical system to obviously elevate the executive capacity; that plus HT7 would reveal an effect similar to but rather weaker than plus DU20, and effect more to memory; and that plus all the three simultaneously could effect rather roundly multiple aspects of the nervous system related to intellectual activities, to elevate the recognition and enhance the executive capacity.</p><p><b>CONCLUSION</b>Needling on various acupoints like DU20, DU26 and HT7 have effects on different brain areas.</p>

Effect of electro-scalp acupuncture on cerebral dopamine transporter in the striatum area of the patient of Parkinson's disease by means of single photon emission computer tomography / 中国针灸

<p><b>OBJECTIVE</b>To probe the mechanism of electro-scalp acupuncture in treatment of Parkinson's disease (PD) by single photon emission computer tomography (SPECT).</p><p><b>METHODS</b>Five cases of PD received electro-scalp acupuncture at Dingnie Qianxiexian (MS 6), Epangxian III (MS 4), Dingpangxian I (MS 8), Dingpangxian II (MS 9) and Zhenxia Pangxian (MS 14). Contralateral points were selected for pathologic change on one side and bilateral points were selected for pathologic lesion on both sides. All the patients received 99mTc-TRODAT-1 SPECT examination before and after acupuncture treatment of 6 weeks. And activities of dopamine transporter (DAT) were analyzed by the ratio of striatum/occipital lobe (ST/OC), which was evaluated by means of technique of regional of interesting (ROI).</p><p><b>RESULTS</b>The ratio of ST/OC on the same side of the affected extremity before and after treatment were 1.19 +/- 0.15 and 1.24 +/- 0.31 respectively. And on the other side were 0.90 +/- 0.12 and 0.95 +/- 0.25 respectively. They were increased after treatment (P > 0.05).</p><p><b>CONCLUSION</b>Electro-scalp acupuncture can decrease the loss of DAT and improve the activities of DAT in the striatum of the patient of PD.</p>

Effect of scalp acupuncture on glucose metabolism in brain of patients with depression / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effect of scalp acupuncture (SA) on the glucose metabolism in different regions of brain in patients with depression by positron emission computed tomography (PET).</p><p><b>METHODS</b>Twelve depressive patients were treated by scalp acupuncture on middle line of vertex (MS5), middle line of forehead (MS1) and bilateral lateral line 1 of forehead (MS2), once a day for six days per week, and received PET detection on different region of brain before and after 6 weeks acupuncture treatment. Semiquantitative analysis was used to compare the average values of radioactive count gotten from various brain regions before and after treatment, which could reflect the condition of glucose metabolism at the brain region detected.</p><p><b>RESULTS</b>SA could increase the glucose metabolism at bilateral frontal lobes, bilateral parietal lobes, right occipital lobe, right caudate nucleus, right cingulated gyrus and left cerebellum and decrease that at right temporal lobe and bilateral thalamus.</p><p><b>CONCLUSION</b>SA on MS5, MS1 and MS2 in depressive patients could influence the glucose metabolism in various brain regions. It primarily illustrated that the mechanism of SA in treating depression is related with its regulation on cortex-limbic circuitry dysfunction and increase the glucose metabolism in various brain regions.</p>
