METHODS: Two hundred and thirty three MCI patients were randomly divided into three groups: the drug group, the scalp electroacupuncture group, and the syndrome differentiation group. For the scalp electroacupuncture group, the points of Baihui (DU 20), Sishecong (EX-HN1), Fengchi (GB 20), and Shenting (DU 24) were selected. For the syndrome differentiation group, specific acupoints were added on the basis of syndrome differentiation and according to the scale for the differentiation of syndromes in vascular dementia (SDSVD) beside the acupoints used in the scalp electroacupuncture group. For the drug group, nimodipine was orally administered. Each patient was treated for two courses, eight weeks. The score differences in minimental state examination (MMSE), picture recognition, and clock drawing test were observed before and after the treatment. RESULTS: After treatment, the score differences in MMSE and clock drawing test were of obvious statistical significance among three groups (P<0.01, P<0.05). The score differences in picture recognition were of extremely statistical significance between the scalp electroacupuncture group and the syndrome differentiation group (P<0.01), while the difference was not found in the drug group (P>0.05). There were statistical significant differences in therapeutic effects between the scalp electroacupuncture group and the drug group, and between the syndrome differentiation group and the drug group (P<0.05), while no statistical difference was found between scalp electroacupuncture group and the syndrome differentiation group (P>0.05). CONCLUSION: All the three therapies may improve the cognitive function of MCI patients. The therapeutic effects in the scalp electroacupuncture and syndrome differentiation groups were basically the same, but superior to nimodipine.展开更多
OBJECTIVE: To investigate the effects of electroacupuncture(EA) at the Guanyuan(CV 4) or Sanyinjiao(SP 6) acupoints on the hypothalamus-pituitary-ovary(HPO) axis and spatial learning and memory in female mice.METHODS:...OBJECTIVE: To investigate the effects of electroacupuncture(EA) at the Guanyuan(CV 4) or Sanyinjiao(SP 6) acupoints on the hypothalamus-pituitary-ovary(HPO) axis and spatial learning and memory in female mice.METHODS: Nine-month-old female mice with senescence-accelerated mouse prone 8(SAMP8)were divided into three groups: the disease model,EA-Guanyuan and EA-Sanyinjiao groups. Concurrently, 9-month old female mice with senescence-accelerated mouse resistance 1(SAMR1)were set as the control model group. The two treatment groups were given the same pattern of EA stimulation. Gonadotropin-releasing hormone, luteinizing hormone, follicle-stimulating hormone(FSH) and Serum estradiol levels in the Hypothalamus-pituitary-ovary axis were assessed by enzyme-linked immunosorbent assay to determinethe HPO axis function level. Spatial learning and memory were assessed by the Morris Water Maze(MWM) test.RESULTS:(a) HPO axis: compared with the control model group, the disease model group displayed a decrease in E2 levels(P < 0.01), and an increase in Gn RH, LH and FSH levels(P < 0.01). E2 levels were increased in EA treatment groups compared with the disease model group(P < 0.05). In contrast,Gn RH and LH and FSH levels were reduced(P <0.05). EA-Sanyinjiao group was superior than EA-Guanyuan group on increasing E2 and declining Gn RH levels(P < 0.01).(b) The MWM test demonstrated that the response latency in the EA-Sanyinjiao treatment group declined from day 2 to day5 compared with the disease model group(P <0.05), whereas the EA-Guanyuan treatment group showed no significant difference.CONCLUSION: EA can regulate hormone(E2, FSH,LH, Gn RH) levels in the HPO axis and the spatial learning and memory ability in female SAMP8 mice. Moreover, this effect may have been more pronounced in the EA-Sanyinjiao group than the EA-Guanyuan group. The underlying mechanism of the EA-induced changes may be related to gonadal hormone shifts in the HPO axis, followed by an improvement in spatial learning and memory.展开更多

The therapeutic effects may be influenced by a variety of factors.Stimulation quantity is one of the factors for achieving good therapeutic effects in acupuncture practice. With the development of science and technology, besides the influence of manual manipulations, the parameters adopted for electroacupuncture have become the benchmark of stimulation quantity. This study, by referring to the related literatures, is designed to explore the influence of manual manipulations and electrical parameters on therapeutic effects of acupuncture. The results from the present study show that different manualmanipulations and electrical parameters may exert different therapeutic effects of acupuncture, which are closely related to the characteristics of diseases.Different manual manipulations and electrical parameters should be adopted according to syndrome differentiation of TCM. This is very important in acupuncture treatment.展开更多
OBJECTIVE: To investigate the effect of electroacupuncture(EA) at acupoints on the pericardium meridian on the expression of phosphorylated Akt(p-Akt) protein in rat myocardium after ischemia and reperfusion.METHODS: ...OBJECTIVE: To investigate the effect of electroacupuncture(EA) at acupoints on the pericardium meridian on the expression of phosphorylated Akt(p-Akt) protein in rat myocardium after ischemia and reperfusion.METHODS: Seventy Wistar rats were evenly randomized into seven groups: the sham operation group(group A), ischemia-reperfusion model Ⅰgroup(group B), ischemia-reperfusion model Ⅱgroup(group C), EA at Neiguan(PC 6) group(group D), EA at Ximen(PC 4) group(group E), EA at Hegu(LI 4) group(group F), and LY294002 + EA at Neiguan(PC 6) group(group G). All processes were monitored by electrocardiography. In group A, the left anterior descending coronary artery was only threaded without ligation for 100 min. In group B,the left anterior descending coronary artery was ligated for 40 min and reperfused for 60 min. The left anterior descending coronary artery in group C was ligated for 40 min and reperfused for 100 min.Groups D, E, and F received EA for 20 min before undergoing ischemia for 40 min, and then received EA for 20 min before undergoing reperfusion for 60 min. Before modeling, group G was injected with LY294002(0.3 mg/kg) into the tail vein, and then underwent the same intervention as the other EA groups. After reperfusion, myocardial tissue from the left cardiac ventricle was collected to enable Western blot analysis of the p-Akt level, and analysis of electrocardiographic changes.RESULTS: In groups B and C, electrocardiography showed obvious elevation of the ST-segment Ⅱlead(ECG-STⅡ), while the ECG-STⅡvalues were significantly lower in groups D, E, and G(P < 0.01). The p-Akt levels in groups D and E were significantly greater than those in groups B and C(P < 0.01).Compared with all other groups, group G showed a significantly different expression of p-Akt(P < 0.01).CONCLUSION: The expression of p-Akt protein in cardiomyocytes was significantly greater in rats that were injected with LY294002 and received EA at Ximen(PC 4) compared with all other groups.This suggests that EA at Ximen(PC 4) resulted展开更多
