ABSTRACT
Objective:To observe the effects of electroacupuncture(EA)on sleep electroencephalogram(EEG)and event-related potential(ERP)in patients with somatoform disorders(SFD). Methods:Seventy-five SFD patients were recruited as an EA group to receive EA at Shenting(GV24)and Baihui(GV20)once daily,30 min each time,with 6 straight days as a treatment course,and 4 courses were conducted at 1-day intervals.Before treatment,patients underwent a survey using a physical symptom checklist on their primary symptoms.Before and after treatment,their sleep EEG was monitored using Quisi,and the ERP mismatch negativity(MMN)and P300 were detected.The Quisi sleep EEG and ERP were also examined among 40 normal volunteers as the normal group data. Results:During the trial,13 cases were removed from the EA group due to incomplete data,and 62 cases were finally included for statistical analyses.Of the 62 SFD patients,the main disturbing symptoms were cognitive impairments,sleep disorders,respiratory symptoms,digestive symptoms,five-sense organ problems,and cardiovascular symptoms in order.Before treatment,the EA group had increased MMN and P300 latencies and decreased amplitudes compared with the normal control group(P<0.01 or P<0.05);according to Quisi,the EA group also had reduced total sleep time(TST),shorter rapid eye movement sleep(REM)latency(RL)and REM time(RT),smaller number of REM period(NRP),extended sleep latency(SL),longer awaking time(AT),lower sleep efficiency(SE),larger percent of non-rapid eye movement sleep(NREM)stage 1(S1)and smaller percent of NREM stage 2(S2),and the percent of slow wave sleep(SWS),i.e.NREM stage 3(S3)plus stage 4(S4),also went down,all presenting significant differences between groups(P<0.01 or P<0.05).After 4 courses of treatment,the MMN and P300 latencies were reduced,and their amplitudes became larger in the EA group compared with the baseline(P<0.05);they had insignificant differences compared with the normal control group(P>0.05).Quisi showed that the TST and RL increased,and the SL and AT decreased in the EA group,and the predominant change in sleep architecture was reduced S1 percent,increased S2,and improved SE,all showing significant intra-group differences(P<0.01 or P<0.05);however,the intra-group difference in the NRP was statistically insignificant(P>0.05).Except the TST,RT,S1 percent,and SWS,there was no statistical significance in comparing the other Quisi parameters(including RL,NRP,SL,AT,SE,and S2 percent)between the two groups(P>0.05). Conclusion:SFD patients have a variety of clinical symptoms,and most of them show abnormal sleep EEG and ERP;EA can correct abnormal sleep EEG parameters and the MMN and P300 of ERP in SFD patients.
ABSTRACT
Objective:To investigate the alteration of delayed memory and its relationship with neurogenesis and angiogenesis in vascular dementia (VD) rats after moxibustion therapy. Methods: Two hundred adult male SPF Wistar rats were chosen for the experiment. Thirty-six rats were randomly selected as the sham operation group. Except for rats in the sham operation group (n=36), the others were made into VD models by bilateral common carotid arteries occlusion (BCCAo). After modeling, the 108 survived rats were randomly divided into 3 groups: a model group, a neural stem cells (NSCs) plus endothelial progenitor cells (EPCs) moxibustion group and a NSCs moxibustion group. Co-transplanted implant was transplanted into the rats in the NSCs plus EPCs moxibustion group, and the rats in the NSCs moxibustion group were transplanted by NSCs only. The NSCs plus EPCs moxibustion group and the NSCs moxibustion group received suspended moxibustion therapy at Baihui (GV 20), Dazhui (GV 14) and Shenting (GV 24), (each group was divided into 3 subgroups by the treatment course as 1, 2 and 3 courses). Every group was measured by Morris water maze to evaluate its delayed memory after 3 treatment courses and the rat’s brain was taken out after perfusion of 4% paraformaldehyde one day after 1, 2 and 3 treatment courses, respectively. Marker protein expression was detected by laser confocal microscope to analyze the effect on neurogenesis and angiogenesis. Results: VD rats showed delayed memory in Morris water maze test 3 d after ischemic injury. After 3 courses of moxibustion therapy, VD-induced delayed memory deficits were improved in the NSCs plus EPCs moxibustion group and the NSCs moxibustion group. The expressions of nestin, doublecortin (DCX) and CD34 increased significantly in the two moxibusiton groups after every treatment course (all P＜0.05), which might contribute to the neurogenesis and angiogenesis in hippocampus. In addition, compared with the rats in the NSCs moxibustion group, the expressions of nestin, DCX and CD34 increased significantly in the NSCs plus EPCs moxibustion group (P＜0.05). Conclusion: Moxibustion can reverse VD-induced delayed memory deficits, which may be related to the promotion of neurogenesis and angiogenesis.
ABSTRACT
Sixty cases of acute lumbar sprain were treated by puncturing Yintang(Ex-HN 3) toward Shenting(GV 24), among which, 50 cases were cured, 9 were improved and only one failed, and the total effective rate was 98.3%.
