METHODS： Sixty SD rats were randomly divided into 6 groups： normal control group, model group （group with gastric mucosal damage, GMD）, Sibai group （with acupuncture at Sibai point ＋ GMD）, Tianshu group （with acupuncture at Tianshu point ＋ GMD）, Zusanli group （with acupuncture at Zusanli point ＋ GMD） and non-acupoint group （with acupuncture at non-acupoint ＋ GMD）. The GMD model group was induced by infusing pure alcohol into gastric cavity. H2 Gas Clearance Test （HGCT） was used to measure GMBF, the frequency and amplitude of gastric motility were measured by the method of aerocyst, the content of brain-gut peptide in sinus ventriculi and bulbus medullae were detected by radioimmunoassay. RESULTS： Inhibitory effect of the frequency and amplitude of gastric motility were shown in model group, and the rates of frequency and amplitude changes were remarkably different from the normal control group （-19.41 ± 17.21 vs-4.71 ± 10.32, P 〈 0.05; -51.61 ± 29.02 vs 1.81 ± 14.12, P 〈 0.01）. In comparison with control group, the GMBF was 0.52 ± 0.161 mL vs 1.03 ± 0.255 mL per 100g tissue/min, P 〈 0.01, the content of motilin in sinus ventriculi and bulbus medullae was 63.04 ± 7.77 pg/mL vs 72.91 ± 8.42 pg/mL, P 〈 0.05 and 50.96 ± 8.77 pg/mL vs 60.76 ± 8.05 pg/mL, P 〈 0.05, but the content of somatostatin in sinus ventriculi and bulbus medullae was 179.85 ± 43.13 ng/g vs 90.54 ± 40.42 ng/g, P 〈 0.01 and 532.86 ± 122.58 ng/g vs 370.91 ± 76.29 ng/g, P 〈 0.05,respectively. In comparison with model group, the amplitude of gastric motility was 1.52 ± 20.13, -6.52 ± 23.31, 6.92 ± 25.21 vs -51.61 ± 29.02, P 〈 0.01 and GMBF was 0.694 ± 0.160 mL vs 0.893 ± 0.210 mL, 1.038 ± 0.301 mL vs 0.52 ± 0.161 mL per 100g tissue/rain, P 〈 0.01, respectively in Tianshu, Sibai and Zusanli groups, the content of motilin in sinus ventriculi and bulbus medullae was 71.64 ± 9.35 pg/mL vs 63.04 ± 7.77 pg/mL, P 〈 0.05; 58.96 ± 6.69 pg/mL vs 50.96 ± 8.77 pg/mL, P 〈 0.05 in Zusanli group and 72.84 ± 8.62 pg/mL vs 63.04 ± 7.77 pg/mL, P 〈 0.05 in Sibai group, while the content of somatostatin in bulbus medullae in Tianshu, Sibai and Zusanli groups was 480.62 ± 151.69 ng/g, 388.53 ± 155.04 ng/g, 365.76 ± 143.93 ng/g vs 532.86 ± 122.58 ng/g, P 〈 0.05, respectively. CONCLUSION： Electro-acupuncture at acupoints of Foot-Yangming Meridian could enhance the gastric motility, improve GMBF, and regulate the content of motUin and somatostatin in sinus ventriculi and bulbus. The effects of acupuncture on GMBF and gastric motility may be related to the content of brain-gut peptide.展开更多

Dendritic atrophy and synaptic loss in Alzheimer＇s disease brain are positively correlated with cognitive damage. Therefore, we speculated that the effect of acupuncture on improving cognitive function may be associated with reduced dendritic damage in the brain. Acupuncture at Qihai（CV6）, Zhongwan（CV12）, Danzhong（CV17）, bilateral Zusanli（ST36）, and bilateral Xuehai（SP10） acupoints was performed once a day（1-day rest after 6-day treatment） for 14 consecutive days. Senescence-accelerated mouse prone 8（SAMP8） mice without acupuncture and senescence-accelerated mouse resistant 1（SAMR1） mice were used as normal controls. After 14 days of treatment, spatial learning and memory ability of mice was assessed in each group using the Morris water maze. Dendritic changes of pyramidal cells in the hippocampal CA1 region were analyzed by quantitative Golgi staining. Our results showed that acupuncture shortened escape latency and lengthened retention time of the former platform quadrant in SAMP8 mice. Further, SAMP8 mice exhibited a significant increase in the number of apical and basal dendritic branches and total length of apical and basal dendrites after acupuncture. These results suggest that acupuncture improves spatial learning and memory ability of middle-aged SAMP8 mice by ameliorating dendritic structure.Acupuncture can improve the cognitive state of Alzheimer＇s disease, but its mechanism is not clear.

The effects of EA at ST25 were measured in male Sprague-Dawley rats, some of which were treated with propranolol or clenbuterol(EA intensities: 1, 3, 5, 7, and 9 m A), and in male transient receptor potential vanilloid-1(TRPV1)(capsaicin receptor) knockout mice(EA intensities: 1, 2, and 4 m A).RESULTS: Anesthetized rats exhibited three types of fasting jejunal motor patterns(types A, B, and C), and only type C rats responded to EA stimulation. In type C rats, EA at ST25 significantly suppressed the motor activity of the jejunum in an intensity-dependent manner. The inhibitory effect of EA was weakened by propranolol(β adrenoceptor antagonist) and disappeared with clenbuterol(β adrenoceptor agonist) induced inhibition of motility, suggesting that the effect of EA on motility is mediated via a sympathetic pathway. Compared with wild-type mice, EA at ST25 was less effective in TRPV1 knockout mice, suggesting that this multi-modal sensor channel participates in the mechanism. CONCLUSION: EA at ST25 was found to inhibit jejunal motility in an intensity-dependent manner, via a mechanism in which sympathetic nerves and TRPV1 receptors play an important role.展开更多

Acupuncture can improve lung function in patients with COPD, but the underlying mechanisms are not well understood. Orexins （OXs）, which are found in peripheral plasma, are neuropeptides that regulate respiration and their levels are related to COPD. Therefore, we hypothesized that acupuncture might alter OXs, reduce lung inflammation and improve lung function in COPD. METHODS： COPD was induced in rats by exposure to cigarette smoke for 8 weeks and injecting with lipopolysaccharide twice. Electroacupuncture （EA） was performed at Feishu （BL13） and Zusanli （ST36） for 30 min/d for 2 weeks. Rat lung function and morphology were assessed after EA. The levels of tumor necrosis factor-α （TNF-a） and intedeukin-1β （IL-16） in bronchoalveolar lavage fluid （BALF） and orexin A and B levels in the lung tissue were detected by enzyme-linked immunosorbent assay. OX receptor mRNA levels and immunopositive cells were assessed with real-time polymerase chain reaction and immunohistochemical methods, respectively. The relationships among lung function, cell factors, and OX levels were analyzed by Pearson correlation analyses. RESULTS： Compared with the control group, lung function was significantly decreased in the rats with COPD （P〈0.05）. There were obvious increases in TNF-α and IL-1β levels in BALF （P〈0.05 and P〈0.01, respectively）, orexin A level in lung tissue （P〈0.01; but not orexin B） and mRNA expressions of OX 1 type receptor （OXR1） and OX 2 type receptor （OXR2） in lung tissue （P〈0.05 and P〈0.01, respectively）; the integrative optical densities （IODs） of both receptors were greater in the COPD group （P〈0.05）. For rats with COPD subjected to EA, lung function was improved （P〈0.05）. There were notable decreases in TNF-a and IL-1β levels （P〈0.05 and 〈0.01, respectively） in BALF. Orexin A, but not orexin B, levels in lung tissue also decreased （P〈0.01）, as did mRNA expression of OXlR and OX2R in lung tissue （P〈0.05 and P〈0.01, respectively）. Receptor IODs were also reduced after EA treatment （P〈0.05）. Furthermore, orexin A levels and ratio of forced expiratory volume in 0.3 s to forced vital capacity were strongly negatively correlated （P〈0.01）, and orexin A was positively correlated with TNF-α and IL-1β （P〈0.001 and P〈0.05, respectively）.CONCLUSION： EA at Zusanli and Feishu improved lung function of rats with COPD and had an anti-inflammatory effect, which may be related to down-regulation of OXA and its receptors.展开更多

In the 7th week after the procedure, rats were randomly divided into a model group(MG), electroacupuncture group(EA), and sham electroacupuncture group(S-EA). After treatment, the abdominal withdrawal reflex(AWR) score was used to assess the behavioral response of visceral hyperalgesia. Immunohistochemistry(En Vision method), ELISA, and fluorescence quantitative PCR methods were applied to detect the expression of CRH protein and m RNA in the colon, spinal cord, and hypothalamus.RESULTS: The sensitivity of the rats to the colorectal distension stimulus applied at different strengths(20-80 mm Hg) increased with increasing stimulus strength, resulting in increasing AWR scores in each group. Compared with NG, the AWR score of MG was significantly increased(P < 0.01). After conducting EA, the AWR scores of the rats were decreased compared with MG rats. The relative expression of CRH m RNA in the colon, spinal cord, and hypothalamus of MG rats was significantly increased compared with NG rats(P < 0.01). CRH m RNA in the colon and spinal cord of EA and S-EA rats was decreased to varying degrees(P > 0.05) compared with normal rats(NG). However, the decrease in EA compared with MG rats was statistically significant(P < 0.01). The average optical density of CRH expression in the colon of the MG rats was significantly enhanced compared with NG(P < 0.05), while the average optical density of CRH expression in the EA and S-EA rats was significantly decreased compared with MG rats(P < 0.01, P < 0.05, respectively). Compared with MG rats, the CRH concentration in the spinal cord of EA rats was significantly reduced(P < 0.01), but there was no significant change in S-EA rats(P > 0.05).CONCLUSION: Electroacupuncture at the Shangjuxu acupoint was able to significantly reduce the visceral hypersensitivity in rats, and regulated the expression of CRH protein and m RNA in the colon, spinal cord and hypothalamus at different levels, playing a therapeutic role in this model of irritable bowel syndrome.展开更多

METHODS EA at 1 m A and 3 m A and Mox at 43?℃ and 46?℃ were applied to the Shangjuxu(ST37, bilateral) acupoints in model rats with visceral hypersensitivity. Responses of wide dynamic range neurons in dorsal horns of the spinal cord were observed through the extracellular recordings. Mast cells(MC) activity in the colons of rats were assessed, and 5-hydroxytryptamine(5-HT), 5-hydroxytryptamine 3 receptor(5-HT3R) and 5-HT4Rexpressions in the colons were measured.RESULTS Compared with normal control group, responses of wide dynamic range neurons in the dorsal horn of the spinal cord were increased in the EA at 1 m A and 3 m A groups(1 m A: 0.84 ± 0.74 vs 2.73 ± 0.65, P < 0.001; 3 m A: 1.91 ± 1.48 vs 6.44 ± 1.26, P < 0.001) and Mox at 43?℃ and 46?℃ groups(43?℃: 1.76 ± 0.81 vs 4.14 ± 1.83, P = 0.001; 46?℃: 5.19 ± 2.03 vs 7.91 ± 2.27, P = 0.01). MC degranulation rates and the expression of 5-HT, 5-HT3 R and 5-HT4 R in the colon of Mox 46?℃ group were decreased compared with model group(MC degranulation rates: 0.47 ± 0.56 vs 0.28 ± 0.78, P < 0.001; 5-HT: 1.42 ± 0.65 vs 7.38 ± 1.12, P < 0.001; 5-HT3R: 6.62 ± 0.77 vs 2.86 ± 0.88, P < 0.001; 5-HT4R: 4.62 ± 0.65 vs 2.22 ± 0.97, P < 0.001). CONCLUSION The analgesic effects of Mox at 46?℃ are greater than those of Mox at 43?℃, EA 1 m A and EA 3 m A.展开更多

In the electric acupuncture group, 170 patients were treated with electric acupuncture and routine therapy, and170 patients in the control group with routine therapy alone. Major indexes for judging curative effect were Barthel index at 3- and 6- months follow-up visits and number of re-hospitalized patients. Mi-nor indexes for judging curative effect were change in the score for nervous dysfunction at 4and 12 weeks follow-up visits and number of patients persisting in rehabilitation treatment with acupuncture during follow-up visit.RESULTS: Baseline data at the time of case selection between the two groups were similar. The odds ratio(OR) was 0.92, and the 95% confidence interval(CI) was 0.49-1.73 in disabled rate and 0.73 and 0.51-1.05 in the number of re-hospitalized patients in the electric acupuncture group at 6-month follow up visit compared with the control group.There was no difference in the score for nervous dysfunction at the end of 12-week follow-up visit between the two groups. The score for nervous dysfunction at the end of 4-week treatment in the electric acupuncture group was significantly higher than that in the control group(P<0.05). The number of patients discharged from hospital who persisted in rehabilitation treatment with acupuncture in the acupuncture group was significantly higher than that in the control group.CONCLUSION: Using electric acupuncture to treat patients with acute ischemic cerebral apoplexy can effectively improve the nervous dysfunction scores after 4-week treatment and their ability to deal with daily life after 6-month follow-up visit. Systematic treatment with acupuncture may also reduce the number of patients with secondary apoplexy.展开更多

文摘The significance of glial cells in the nervous system,particularly in the modulation of pain,has increasingly gained prominence,thereby shifting the traditional neurobiological research paradigm that predominantly focused on neurons.Acupuncture treatment have been shown to influence the functionality of glial cells,enabling them to serve as modulators that significantly contribute to the inhibition of neurogenic inflammation,the restoration of synaptic homeostasis,and the enhancement of the pain modulation system.Furthermore,various molecules and their associated signaling pathways facilitate the biological effects of glial cells in the context of acupuncture-induced analgesia.Notably,P2X receptors(P2X3,P2X4,and P2X7),the MAPK pathway(including p38MAPK and ERK),and the JAK/STAT pathway within glial cells are implicated in the modulation of neuroinflammation and pain regulation through acupuncture.These elucidated mechanisms underscore the potential of acupuncture to modulate neuroimmune signaling for pain alleviation and suggest the prospect of developing more targeted and effective treatments for chronic pain in the future.

文摘Objective To investigate the mechanism of in alleviating colonic mucosal inflammation in ten-eleven translocation(TET)protein 2 gene knockout(TET2^(-/-))mice with ulcerative colitis(UC)by regulating DNA methyltransferase(DNMT)and DNA hydroxymethylase.Methods Male specific pathogen-free(SPF)grade C57BL/6J wild-type(WT)mice(n=8)and TET2^(-/-)mice(n=20)were used to establish UC models by freely drinking 3%dextran sulfate sodium solution for 7 d.After UC model validation through histopathological examination in two mice from each type,the remaining mice were divided into four groups(n=6 in each group):WT model(WT+UC),TET2^(-/-)model(TET2^(-/-)+UC),TET2^(-/-)mild moxibustion(TET2^(-/-)+MM),and TET2^(-/-)electroacupuncture(TET2^(-/-)+EA)groups.TET2^(-/-)+MM group received mild moxibustion on Tianshu(ST25)and Qihai(CV6)for 10 min daily for 7 d.The TET2^(-/-)+EA group also applied electroacupuncture(1 mA,2/100 Hz)at the same acupoints for 10 min daily for 7 d.The disease activity index(DAI)scores of each group of mice were accessed daily.The colon lengths of mice in groups were measured following intervention.The pathological changes in the colon tissues were observed with hematoxylin and eosin(HE)staining.The concentrations of interleukin(IL)-6,C-C motif chemokine 17(CCL17),and C-X-C motif chemokine ligand 10(CXCL10)in serum were detected by enzyme-linked immunosorbent assay(ELISA).The expression of DNMT proteins(DNMT1,DNMT3A,and DNMT3B)in the colon tissues was detected by immunohistochemistry.The expression of 5-methylcytosine(5-mC),5-hydroxymethylcytosine(5-hmC),histone deacetylase 2(HDAC2),and DNA hydroxymethylase family proteins(TET 1 and TET3)was detected using immunofluorescence,which also determined the co-localization of TET1 and IL-6 protein.Results Compared with WT+UC group,TET2^(-/-)+UC group exhibited significantly higher DAI scores and shorter colon lengths(P<0.01).Both mild moxibustion and electroacupuncture significantly decreased DAI scores and ameliorated colon shortening in TET2^(-/-)mice(P<0.001).Histopathological scores of TET2^(-/-)+UC mice were significantly higher than those of WT+UC group(P<0.001)and were significantly reduced after both mild moxibustion and electroacupuncture interventions(P<0.001).Serum levels of IL-6,CCL17,and CXCL10 were significantly elevated in TET2^(-/-)+UC group compared with WT+UC group(P<0.001).Mild moxibustion significantly reduced IL-6,CCL17,and CXCL10 levels(P<0.001,P<0.001,and P<0.01,respectively),while electroacupuncture also significantly reduced IL-6,CCL17,and CXCL10 levels(P<0.05,P<0.01,and P<0.01,respectively).TET2^(-/-)+UC mice showed increased expression levels of DNMT1,DNMT3A,DNMT3B,and 5-mC(P<0.05,P<0.01 and P<0.001,respectively),with decreased expression levels of TET1,TET3,5-hmC,and HDAC2(P<0.001).Mild moxibustion significantly reduced DNMT1,DNMT3B,and 5-mC levels(P<0.05,P<0.01,and P<0.001,respectively),while increasing expression levels of TET1,TET3,5-hmC,and HDAC2(P<0.001,P<0.001,P<0.05,and P<0.001,respectively).Electroacupuncture significantly decreased 5-mC and DNMT3B levels(P<0.001 and P<0.01,respectively)and increased 5-hmC and HDAC2 levels(P<0.05 and P<0.001,respectively),but did not significantly affect TET1 and TET3 expression(P>0.05).Compared with TET2^(-/-)+MM group,TET2^(-/-)+EA group showed significantly higher 5-mC expression(P<0.001).TET2^(-/-)+UC group exhibited markedly increased IL-6 expression and higher co-localization of TET1 and IL-6 in mucosal epithelium,whereas minimal IL-6 expression was observed in the other groups.Conclusion Mild moxibustion and electroacupuncture significantly ameliorate colonic inflammation exacerbated by TET2 deficiency in UC mice via epigenetic modulation.Distinct mechanisms exist between the two interventions:mild moxibustion regulates both DNMT and hydroxymethylase,whereas electroacupuncture primarily affects DNMT.

文摘Objective:To construct a clinical prediction model of acupuncture treatment for diminished ovarian reserve(DOR)based on a machine learning algorithm to provide a clinical prediction of acupuncture for ameliorating pregnancy outcomes in DOR.Methods:We enrolled 377 DOR patients treated with acupuncture and with records of pregnancy outcomes(139 cases of pregnancy and 238 cases failed)exported from the International Patient Registry Platform of Acupuncture-moxibustion(IPRPAM).The predictive variables were determined using Spearman’s correlation analysis and feature engineering methods.The model was constructed by adopting logistic regression,naïve Bayes,random forest,support vector machine,extreme gradient boosting,the knearest neighbor algorithm,linear discriminant analysis,and neural network methods.The models were validated by the area under the curve(AUC),accuracy(ACC),and importance sequencing,and individual pregnancy prediction was conducted for the best-performing model.Results:The key factors determining pregnancy after acupuncture in patients with DOR were age,luteinizing hormone(LH)level after treatment,follicle-stimulating hormone(FSH)level after treatment,the ratio of FSH to LH(FSH/LH)after treatment,and history of acupuncture treatment.Random forest model ACC was 0.95,Fβwas 0.93,Logloss was 0.30,Logloss value was the lowest,the model variables exhibited the highest accuracy and precision.Conclusion:The random forest model for the effects of acupuncture on pregnancy outcomes in patients with DOR,constructed based on the IPRPAM,presents a favorable value for clinical application.
文摘Sham acupuncture,as a control intervention in acupuncture studies,has been widely conducted to eval-uate the specific effect of acupuncture.However,there was no relevant particular reporting guideline,so the reporting quality of sham acupuncture was low,which could hinder the precise understanding and interpretation of details and implementation background of sham acupuncture by researchers.In order to standardize the reporting of sham acupuncture and improve its quality,SHam Acupuncture REporting guidelines and a checklist in clinical trials(SHARE)was developed by a research team from Beijing Univer-sity of Chinese Medicine.The SAHRE standardizes the reporting of sham acupuncture from 10 categories,including brief name,rationales,details of sham acupuncture,treatment regimen of sham acupuncture,the information informed or explained to patients,practitioner information,modifications of protocol,communication between practitioner and patient,practitioner adherence and blinding.This article elab-orates the development process and key content of SHARE in order to facilitate its application by re-searchers.

文摘Background:Acupuncture therapy provides a complementary and alternative approach to treating major depressive disorder(MDD),but its efficacy and safety have still not been comprehensively assessed.Recently published systematic reviews remain confusing and inconclusive.Objective:This systematic review evaluated the efficacy and safety of acupuncture therapy alone or combined with antidepressants for adult patients with mild and moderate MDD.Search strategy:Chinese Biomedical Literature Database,China National Knowledge Infrastructure Database,Wanfang Database,Chinese Science and Technology Journal Database,Pub Med,Embase,and Cochrane Library were searched from their inceptions to March 2025.Inclusion criteria:Randomized controlled trials that compared acupuncture therapy with antidepressants,or acupuncture therapy plus antidepressants with acupuncture therapy or antidepressants for adult patients with mild and moderate MDD were included.Data extraction and analysis:Five reviewers independently extracted data from original literature using a standardized form,and the data were verified by two reviewers to ensure accuracy.Statistical meta-analyses,publication bias analyses,and subgroup analyses were performed by using Review Manager 5.3 software.The Grading of Recommendations Assessment,Development,and Evaluation approach was used to assess the certainty of the evidence.Results:A total of 60 eligible studies including 4675 participants were included.Low-certainty evidence showed that compared with antidepressants,acupuncture therapy(standardized mean difference[SMD]=-0.57;95%confidence interval[CI]=[-0.87,-0.27];I^(2)=86%;P=0.006)or acupuncture therapy plus antidepressants(SMD=-1.00;95%CI=[-1.18,-0.81];I^(2)=77%;P<0.00001)may reduce the severity of depression at the end of treatment.Low-certainty evidence indicated that compared with acupuncture therapy alone,acupuncture therapy plus antidepressants slightly reduced the severity of depression at the end of treatment(SMD=-0.38;95%CI=[-0.61,-0.14];I^(2)=18%;P=0.002).Similar results were also found for acupuncture's relief of insomnia.The reported adverse effects of acupuncture therapy were mild and transient.For most of the subgroup analyses,acupuncture type,scale type,and the course of treatment did not show a significant relative effect.Conclusion:Acupuncture therapy may provide antidepressant effects and relieve insomnia with mild adverse effects for adult patients with mild and moderate MDD.But the certainty of evidence was very low.More high-quality,well designed,large-scale studies with long-term follow-up are needed in the future.

文摘Background:The development of gastric cancer(GC)encompasses precancerous conditions like chronic atrophic gastritis(CAG)and premalignant lesions of gastric cancer(PLGC).In these situations,abnormal Notch signaling results in mucosal impairment and the initiation of cancer.Banxia Xiexin Decoction(BXD),a well-known formula in traditional Chinese medicine(TCM),shows promise in treating gastric disorders,but its mechanisms in gastric restoration remain unclear.Methods:Using MNNG-induced CAG and PLGC rat models,BXD was administered for 12 weeks.Gastric mucosal pathology was assessed via hematoxylin-eosin staining.Proliferation(Ki-67)and angiogenesis(VEGFA)markers were evaluated by immunohistochemistry.Network pharmacology identified BXD’s targets and pathways.Notch pathway components(Notch1,Jagged1,Dll4,Hes1)were analyzed via qPCR,Western blot,and immunohistochemistry.Results:BXD significantly ameliorated mucosal atrophy,glandular structural disorder,and dysplasia in CAG and PLGC rats.Network pharmacology revealed 323 overlapping targets between BXD and PLGC,with Notch signaling as a central pathway.BXD downregulated Notch1,Jagged1,Dll4,and Hes1 expression at transcriptional and protein levels,suppressed Ki-67(proliferation)and VEGFA(angiogenesis)overexpression,and restored gastric mucosal integrity.Conclusion:BXD inhibits Notch signaling,reduces aberrant proliferation and angiogenesis,and interrupts Correa’s gastric carcinogenesis cascade.This study provides mechanistic evidence supporting BXD as a TCM-based intervention for gastric precancerous lesions.

文摘AIM： To observe the effect of acupuncture at Foot- Yangming Meridian on gastric mucosal blood flow （GMBF）, gastric motility and brain-gut peptide. METHODS： Sixty SD rats were randomly divided into 6 groups： normal control group, model group （group with gastric mucosal damage, GMD）, Sibai group （with acupuncture at Sibai point ＋ GMD）, Tianshu group （with acupuncture at Tianshu point ＋ GMD）, Zusanli group （with acupuncture at Zusanli point ＋ GMD） and non-acupoint group （with acupuncture at non-acupoint ＋ GMD）. The GMD model group was induced by infusing pure alcohol into gastric cavity. H2 Gas Clearance Test （HGCT） was used to measure GMBF, the frequency and amplitude of gastric motility were measured by the method of aerocyst, the content of brain-gut peptide in sinus ventriculi and bulbus medullae were detected by radioimmunoassay. RESULTS： Inhibitory effect of the frequency and amplitude of gastric motility were shown in model group, and the rates of frequency and amplitude changes were remarkably different from the normal control group （-19.41 ± 17.21 vs-4.71 ± 10.32, P 〈 0.05; -51.61 ± 29.02 vs 1.81 ± 14.12, P 〈 0.01）. In comparison with control group, the GMBF was 0.52 ± 0.161 mL vs 1.03 ± 0.255 mL per 100g tissue/min, P 〈 0.01, the content of motilin in sinus ventriculi and bulbus medullae was 63.04 ± 7.77 pg/mL vs 72.91 ± 8.42 pg/mL, P 〈 0.05 and 50.96 ± 8.77 pg/mL vs 60.76 ± 8.05 pg/mL, P 〈 0.05, but the content of somatostatin in sinus ventriculi and bulbus medullae was 179.85 ± 43.13 ng/g vs 90.54 ± 40.42 ng/g, P 〈 0.01 and 532.86 ± 122.58 ng/g vs 370.91 ± 76.29 ng/g, P 〈 0.05,respectively. In comparison with model group, the amplitude of gastric motility was 1.52 ± 20.13, -6.52 ± 23.31, 6.92 ± 25.21 vs -51.61 ± 29.02, P 〈 0.01 and GMBF was 0.694 ± 0.160 mL vs 0.893 ± 0.210 mL, 1.038 ± 0.301 mL vs 0.52 ± 0.161 mL per 100g tissue/rain, P 〈 0.01, respectively in Tianshu, Sibai and Zusanli groups, the content of motilin in sinus ventriculi and bulbus medullae was 71.64 ± 9.35 pg/mL vs 63.04 ± 7.77 pg/mL, P 〈 0.05; 58.96 ± 6.69 pg/mL vs 50.96 ± 8.77 pg/mL, P 〈 0.05 in Zusanli group and 72.84 ± 8.62 pg/mL vs 63.04 ± 7.77 pg/mL, P 〈 0.05 in Sibai group, while the content of somatostatin in bulbus medullae in Tianshu, Sibai and Zusanli groups was 480.62 ± 151.69 ng/g, 388.53 ± 155.04 ng/g, 365.76 ± 143.93 ng/g vs 532.86 ± 122.58 ng/g, P 〈 0.05, respectively. CONCLUSION： Electro-acupuncture at acupoints of Foot-Yangming Meridian could enhance the gastric motility, improve GMBF, and regulate the content of motUin and somatostatin in sinus ventriculi and bulbus. The effects of acupuncture on GMBF and gastric motility may be related to the content of brain-gut peptide.

文摘Acupuncture can improve the cognitive state of Alzheimer＇s disease, but its mechanism is not clear. Dendritic atrophy and synaptic loss in Alzheimer＇s disease brain are positively correlated with cognitive damage. Therefore, we speculated that the effect of acupuncture on improving cognitive function may be associated with reduced dendritic damage in the brain. Acupuncture at Qihai（CV6）, Zhongwan（CV12）, Danzhong（CV17）, bilateral Zusanli（ST36）, and bilateral Xuehai（SP10） acupoints was performed once a day（1-day rest after 6-day treatment） for 14 consecutive days. Senescence-accelerated mouse prone 8（SAMP8） mice without acupuncture and senescence-accelerated mouse resistant 1（SAMR1） mice were used as normal controls. After 14 days of treatment, spatial learning and memory ability of mice was assessed in each group using the Morris water maze. Dendritic changes of pyramidal cells in the hippocampal CA1 region were analyzed by quantitative Golgi staining. Our results showed that acupuncture shortened escape latency and lengthened retention time of the former platform quadrant in SAMP8 mice. Further, SAMP8 mice exhibited a significant increase in the number of apical and basal dendritic branches and total length of apical and basal dendrites after acupuncture. These results suggest that acupuncture improves spatial learning and memory ability of middle-aged SAMP8 mice by ameliorating dendritic structure.Acupuncture can improve the cognitive state of Alzheimer＇s disease, but its mechanism is not clear.

文摘AIM: To investigate whether electroacupuncture(EA) at ST25 affects jejunal motility in vivo and if so, whether a sympathetic pathway is involved.METHODS: Jejunal motility was assessed using a manometric balloon placed in the jejunum approximately about 3-5 cm away from the suspensory ligament of the duodenum in anesthetized animals. The effects of EA at ST25 were measured in male Sprague-Dawley rats, some of which were treated with propranolol or clenbuterol(EA intensities: 1, 3, 5, 7, and 9 m A), and in male transient receptor potential vanilloid-1(TRPV1)(capsaicin receptor) knockout mice(EA intensities: 1, 2, and 4 m A).RESULTS: Anesthetized rats exhibited three types of fasting jejunal motor patterns(types A, B, and C), and only type C rats responded to EA stimulation. In type C rats, EA at ST25 significantly suppressed the motor activity of the jejunum in an intensity-dependent manner. The inhibitory effect of EA was weakened by propranolol(β adrenoceptor antagonist) and disappeared with clenbuterol(β adrenoceptor agonist) induced inhibition of motility, suggesting that the effect of EA on motility is mediated via a sympathetic pathway. Compared with wild-type mice, EA at ST25 was less effective in TRPV1 knockout mice, suggesting that this multi-modal sensor channel participates in the mechanism. CONCLUSION: EA at ST25 was found to inhibit jejunal motility in an intensity-dependent manner, via a mechanism in which sympathetic nerves and TRPV1 receptors play an important role.

文摘Inflammation and lung function decline are the main pathophysiological features of chronic obstructive pulmonary disease （COPD）. Acupuncture can improve lung function in patients with COPD, but the underlying mechanisms are not well understood. Orexins （OXs）, which are found in peripheral plasma, are neuropeptides that regulate respiration and their levels are related to COPD. Therefore, we hypothesized that acupuncture might alter OXs, reduce lung inflammation and improve lung function in COPD. METHODS： COPD was induced in rats by exposure to cigarette smoke for 8 weeks and injecting with lipopolysaccharide twice. Electroacupuncture （EA） was performed at Feishu （BL13） and Zusanli （ST36） for 30 min/d for 2 weeks. Rat lung function and morphology were assessed after EA. The levels of tumor necrosis factor-α （TNF-a） and intedeukin-1β （IL-16） in bronchoalveolar lavage fluid （BALF） and orexin A and B levels in the lung tissue were detected by enzyme-linked immunosorbent assay. OX receptor mRNA levels and immunopositive cells were assessed with real-time polymerase chain reaction and immunohistochemical methods, respectively. The relationships among lung function, cell factors, and OX levels were analyzed by Pearson correlation analyses. RESULTS： Compared with the control group, lung function was significantly decreased in the rats with COPD （P〈0.05）. There were obvious increases in TNF-α and IL-1β levels in BALF （P〈0.05 and P〈0.01, respectively）, orexin A level in lung tissue （P〈0.01; but not orexin B） and mRNA expressions of OX 1 type receptor （OXR1） and OX 2 type receptor （OXR2） in lung tissue （P〈0.05 and P〈0.01, respectively）; the integrative optical densities （IODs） of both receptors were greater in the COPD group （P〈0.05）. For rats with COPD subjected to EA, lung function was improved （P〈0.05）. There were notable decreases in TNF-a and IL-1β levels （P〈0.05 and 〈0.01, respectively） in BALF. Orexin A, but not orexin B, levels in lung tissue also decreased （P〈0.01）, as did mRNA expression of OXlR and OX2R in lung tissue （P〈0.05 and P〈0.01, respectively）. Receptor IODs were also reduced after EA treatment （P〈0.05）. Furthermore, orexin A levels and ratio of forced expiratory volume in 0.3 s to forced vital capacity were strongly negatively correlated （P〈0.01）, and orexin A was positively correlated with TNF-α and IL-1β （P〈0.001 and P〈0.05, respectively）.CONCLUSION： EA at Zusanli and Feishu improved lung function of rats with COPD and had an anti-inflammatory effect, which may be related to down-regulation of OXA and its receptors.

文摘The hippocampus is involved in the regulation of the autonomic nervous system,together with the hypothalamus and brainstem nuclei,such as the paraventricular nucleus and nucleus tractus solitarius.The vagus nerve-nucleus tractus solitarius pathway has an important role in cardiovascular reflex regulation.Myocardial ischemia has been shown to cause changes in the autonomic nervous system,affecting the dynamic equilibrium of the sympathetic and vagal nerves.However,it remains poorly understood how the hippocampus communicates with brainstem nuclei to regulate the autonomic nervous system and alleviate myocardial ischemic tissue damage.A rat model of acute myocardial ischemia（AMI） was made by ligating the left anterior descending branch of the coronary artery.Three days before ischemia,the hippocampal CA1 region was damaged.Then,3 days after ischemia,electroacupuncture（EA） at Shenmen（HT7）-Tongli（HT5） was performed（continuous wave,1 m A,2 Hz,duration of 30 minutes）.Cluster analysis of firing patterns showed that one type of neuron was found in rats in the sham and AMI groups.Three types of neurons were observed in the AMI ＋ EA group.Six types of neurons were found in the AMI ＋ EA ＋ Lesion group.Correlation analysis showed that the frequency of vagus nerve discharge in each group was negatively correlated with heart rate（HR）（P 〈 0.05,r =-0.424）,and positively correlated with mean arterial pressure（MAP）（P 〈 0.05,r = 0.40987） and the rate-pressure product（RPP）（P 〈 0.05,r = 0.4252）.The total frequency of the nucleus tractus solitarius discharge in each group was positively correlated with vagus nerve discharge（P 〈 0.01,r = 0.7021）,but not with hemodynamic index（HR： P 〉 0.05,r =-0.03263; MAP： P 〉 0.05,r =-0.08993; RPP： P 〉 0.05,r =-0.03263）.Some neurons（Neuron C） were negatively correlated with vagus nerve discharge,HR,MAP and RPP in the AMI ＋ EA group（vagus nerve discharge： P 〈 0.05,r =-0.87749; HR： P 〈 0.01,r =-0.91902; MAP： P 〈 0.05,r =-0.85691; RPP： P 〈 0.01,r =-0.91902）.Some neurons（Neurons C,D and E） were positively correlated with vagus nerve discharge,HR,MAP and RPP in the AMI ＋ EA ＋ Lesion group（vagus nerve discharge： P 〈 0.01,r = 0.8905,P 〈 0.01,r = 0.9725,P 〈 0.01,r = 0.9054; HR： P 〈 0.01,r = 0.9347,P 〈 0.01,r = 0.9089,P 〈 0.05,r = 0.8247; MAP： P 〈 0.05,r = 0.8474,P 〈 0.01,r = 0.9691,P 〈 0.01,r = 0.9027; RPP： P 〈 0.05,r = 0.8637,P 〈 0.01,r = 0.9407,P 〈 0.01,r = 0.9027）.These findings show that the hippocampus-nucleus tractus solitarius-vagus nerve pathway is involved in the cardioprotective effect of EA at the heart meridian.Some interneurons in the nucleus tractus solitarius may play a particularly important role in the cardiomodulatory process.

文摘AIM: To investigate the effect of electroacupuncture on corticotropin-releasing hormone(CRH) in the colon, spinal cord, and hypothalamus of rats with chronic visceral hypersensitivity.METHODS: A rat model of chronic visceral hypersensitivity was generated according to the internationally accepted method of colorectal balloon dilatation. In the 7th week after the procedure, rats were randomly divided into a model group(MG), electroacupuncture group(EA), and sham electroacupuncture group(S-EA). After treatment, the abdominal withdrawal reflex(AWR) score was used to assess the behavioral response of visceral hyperalgesia. Immunohistochemistry(En Vision method), ELISA, and fluorescence quantitative PCR methods were applied to detect the expression of CRH protein and m RNA in the colon, spinal cord, and hypothalamus.RESULTS: The sensitivity of the rats to the colorectal distension stimulus applied at different strengths(20-80 mm Hg) increased with increasing stimulus strength, resulting in increasing AWR scores in each group. Compared with NG, the AWR score of MG was significantly increased(P < 0.01). After conducting EA, the AWR scores of the rats were decreased compared with MG rats. The relative expression of CRH m RNA in the colon, spinal cord, and hypothalamus of MG rats was significantly increased compared with NG rats(P < 0.01). CRH m RNA in the colon and spinal cord of EA and S-EA rats was decreased to varying degrees(P > 0.05) compared with normal rats(NG). However, the decrease in EA compared with MG rats was statistically significant(P < 0.01). The average optical density of CRH expression in the colon of the MG rats was significantly enhanced compared with NG(P < 0.05), while the average optical density of CRH expression in the EA and S-EA rats was significantly decreased compared with MG rats(P < 0.01, P < 0.05, respectively). Compared with MG rats, the CRH concentration in the spinal cord of EA rats was significantly reduced(P < 0.01), but there was no significant change in S-EA rats(P > 0.05).CONCLUSION: Electroacupuncture at the Shangjuxu acupoint was able to significantly reduce the visceral hypersensitivity in rats, and regulated the expression of CRH protein and m RNA in the colon, spinal cord and hypothalamus at different levels, playing a therapeutic role in this model of irritable bowel syndrome.

文摘AIM To observe whether there are differences in the effects of electro-acupuncture(EA) and moxibustion(Mox) in rats with visceral hypersensitivity. METHODS EA at 1 m A and 3 m A and Mox at 43?℃ and 46?℃ were applied to the Shangjuxu(ST37, bilateral) acupoints in model rats with visceral hypersensitivity. Responses of wide dynamic range neurons in dorsal horns of the spinal cord were observed through the extracellular recordings. Mast cells(MC) activity in the colons of rats were assessed, and 5-hydroxytryptamine(5-HT), 5-hydroxytryptamine 3 receptor(5-HT3R) and 5-HT4Rexpressions in the colons were measured.RESULTS Compared with normal control group, responses of wide dynamic range neurons in the dorsal horn of the spinal cord were increased in the EA at 1 m A and 3 m A groups(1 m A: 0.84 ± 0.74 vs 2.73 ± 0.65, P < 0.001; 3 m A: 1.91 ± 1.48 vs 6.44 ± 1.26, P < 0.001) and Mox at 43?℃ and 46?℃ groups(43?℃: 1.76 ± 0.81 vs 4.14 ± 1.83, P = 0.001; 46?℃: 5.19 ± 2.03 vs 7.91 ± 2.27, P = 0.01). MC degranulation rates and the expression of 5-HT, 5-HT3 R and 5-HT4 R in the colon of Mox 46?℃ group were decreased compared with model group(MC degranulation rates: 0.47 ± 0.56 vs 0.28 ± 0.78, P < 0.001; 5-HT: 1.42 ± 0.65 vs 7.38 ± 1.12, P < 0.001; 5-HT3R: 6.62 ± 0.77 vs 2.86 ± 0.88, P < 0.001; 5-HT4R: 4.62 ± 0.65 vs 2.22 ± 0.97, P < 0.001). CONCLUSION The analgesic effects of Mox at 46?℃ are greater than those of Mox at 43?℃, EA 1 m A and EA 3 m A.

文摘OBJECTIVE: To examine whether electric acupuncture can improve the daily life of patients with ischemic cerebral apoplexy at acute stage.METHODS: A stratified-block randomized controlled multicenter trial was designed for this study.Totally 340 patients with acute ischemic cerebral apoplexy were randomly divided into an electric acupuncture group and a control group. In the electric acupuncture group, 170 patients were treated with electric acupuncture and routine therapy, and170 patients in the control group with routine therapy alone. Major indexes for judging curative effect were Barthel index at 3- and 6- months follow-up visits and number of re-hospitalized patients. Mi-nor indexes for judging curative effect were change in the score for nervous dysfunction at 4and 12 weeks follow-up visits and number of patients persisting in rehabilitation treatment with acupuncture during follow-up visit.RESULTS: Baseline data at the time of case selection between the two groups were similar. The odds ratio(OR) was 0.92, and the 95% confidence interval(CI) was 0.49-1.73 in disabled rate and 0.73 and 0.51-1.05 in the number of re-hospitalized patients in the electric acupuncture group at 6-month follow up visit compared with the control group.There was no difference in the score for nervous dysfunction at the end of 12-week follow-up visit between the two groups. The score for nervous dysfunction at the end of 4-week treatment in the electric acupuncture group was significantly higher than that in the control group(P<0.05). The number of patients discharged from hospital who persisted in rehabilitation treatment with acupuncture in the acupuncture group was significantly higher than that in the control group.CONCLUSION: Using electric acupuncture to treat patients with acute ischemic cerebral apoplexy can effectively improve the nervous dysfunction scores after 4-week treatment and their ability to deal with daily life after 6-month follow-up visit. Systematic treatment with acupuncture may also reduce the number of patients with secondary apoplexy.
