In the apurinic/apyrimidinic endonuclease DNA basic group reparative excision experiments, the apurinic/apyrimidinic endonuclease activity of brain tissue increased slightly after electroacupuncture in rats. In the DNA polymerase β (Pol β)experiments, the Pol β ac-tivity of brain tissue increased after electroacupuncture, especially at DU 26 and PC 6. In the DNA ligase experiments, the expression of DNA ligase 1 in brain tissue increased significantly after electroacupuncture. These findings demonstrate increased activity of apurinic/apyrimidinic en-donuclease, Pol β and DNA ligase 1 after electroacupuncture at DU 26 and PC 6. Also, DNA repair in brain tissue supplied by the middle cerebral artery is promoted after electroacupuncture at DU 26 and PC 6, which are more effective than the LI 11 and ST 36 acupoints .展开更多

Neurological deficit scores, western blotting, and reverse transcription-PCR results demonstrated that electroacupuncture markedly reduced neurological deficits, decreased corpus striatum aquaporin-4 protein and mRNA expression, and relieved damage to the blood-brain barrier in a rat model of cerebral ischemia/reperfusion injury. These results suggest that electroacupuncture most likely protects the blood-brain barrier by regulating aquaporin-4 expression following cerebral ischemia/reperfusion injury.展开更多

Methods: Fifty patients suffering from VD were divided into 5 groups randomly and treated by conventional acupuncture for hemiplegia, or conventional acupuncture plus needling in DU20, DU26, HT7 respectively or simultaneously. Clinical symptoms were observed, and the scales such as Hasegawa's dementia scale-recension (HDS-R), activities of daily living (ADL) and functional activities questionnaire (FAQ) were used for assessment before and after acupuncture treatment. The scores were processed statistically. Results: DU20 and HT7 could improve the abilities of memory, orientation, reaction and reduce adamancy and trance. Bedsides, DU 20 was helpful in improving the abilities of understanding, calculating and social adapting. While DU26 is helpful in treating retardation, failure in daily activities, trance and poor memory. The combination of the 3 acupoints could improve the intelligence and social adapting ability of VD patients. Conclusion: DU20, DU26 and HT7 had its own effect in treating VD, but the effect of three points used in combination was the best.展开更多

Methods: 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. Results: 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. Conclusion: Needling on various acupoints like DU20, DU26 and HT7 have effects on different brain areas.展开更多
