Methods: Healthy male Sprague-Dawley rats were allocated into three groups: Sham group, Model group, and electroacupuncture (Model + EA) group, with each group comprising 8 rats. The model underwent a procedure involving the ligation of the left anterior descending coronary artery to induce a model of heart failure. The Model + EA group was used for 7 consecutive days for electroacupuncture of bilateral Shenmen (HT7) and Tongli (HT5), once a day for 30 min each time. Left ventricular parameters in rats were assessed using a small-animal ultrasound machine to analyze changes in left ventricular end-diastolic volume, left ventricular end-systolic volume, left ventricular ejection fraction, and left ventricular fractional shortening. Serum interleukin-1β (IL-1β), cardiac troponin (cTn), and N-terminal brain natriuretic peptide precursor levels were measured using ELISA. Histopathological changes in rat myocardium were observed through HE staining, while collagen deposition in rat myocardial tissue was assessed using the Masson staining method. Picro sirius red staining, immunohistochemical staining, and RT-qPCR were utilized to distinguish between the various types of collagen deposition. The expression level of TGF-β1 and SMAD2/3/4/7 mRNA in rat myocardial tissues was determined using RT-qPCR. Additionally, western blot analysis was conducted to assess the protein expression levels of TGF-β1, SMAD3/7, and p-SMAD3 in rat myocardial tissues. Results: Compared with the Sham group, the left ventricular ejection fraction and left ventricular fractional shortening values of the Model group were significantly decreased (P < 0.01);the left ventricular end-diastolic volume and left ventricular end-systolic volume values were remarkably increased (P < 0.01);serum N-terminal brain natriuretic peptide precursor content was increased (P < 0.01);serum IL-1β and cTn levels were increased (P < 0.01);myocardial collagen volume fraction were increased (P < 0.01);and those of the expression of TGF-β1 and SMAD2/3/4 mRNA was increased (P < 0.01);the expression of SMAD7 mRNA was decreased (P < 0.01);the protein expression levels of TGF-β1, SMAD3, and p-Smad3 were increased (P < 0.01);the protein expression level of SMAD7 was decreased (P < 0.01) in the Model group. Compared to the Model group, the expression levels of the proteins TGF-β1, SMAD3, and p-Smad3 in myocardial tissue were found to be decreased (P < 0.01), and the expression level of the protein SMAD7 was found to be increased (P < 0.01) in the Model + EA group;the collagen volume fraction and deposition of type Ⅰ /Ⅲ collagen were decreased (P < 0.01) in the Model + EA group. Conclusion: Electroacupuncture alleviates myocardial fibrosis in rats with heart failure, and this effect is likely due to attributed to the modulation of the TGF-β1/Smads signaling pathway, which helps reduce collagen deposition in the extracellular matrix.展开更多

Methods:A total of 36 SD rats were randomly divided into normal group, sham operation group, model group, EA pericardium meridian group, model+D-Ser group,and EA pericardium meridian+D-Ser group. The MCAO model was prepared by Zea Longa method. The model+D-Ser group and the EA pericardium meridian+D-Ser group were given exogenous D-Ser reagent(160 mg/kg i.p.) 30 minutes after the success of the insertion of the suture. EA pericardium meridian group and EA pericardium meridian+D-Ser group were treated with electroacupuncture for 30 min on the next day. The remaining groups were only bound for 30 min.Behavioral evaluation was performed at 6 h after successful modeling and 2 d after intervention, and then the rats were sacrificed. The content of D-Ser in ischemic brain tissue was measured by liquid chromatography tandem mass spectrometry, and the protein expression of NR1, NR2A and NR2B was detected by Western Blot. Results : Before treatment, compared with the normal group and the sham operation group, the behavioral scores of each group increased after modeling (P<0.05 );Compared with the model group, the behavioral scores of the model+D-Ser group and the EA pericardium meridian+D-Ser group were increased (P<0.05).After treatment, compared with the model group, there was no significant difference in the EA pericardium meridian group (P>0.05),The behavioral scores of the model+D-Ser group and the EA pericardium meridian+D-Ser group were still increased (P<0.05);Compared with the model+D-Ser group, the behavioral score of the EA pericardium meridian+D-Ser group was not statistically significant (P>0.05).Comparison before and after treatment in the group,except for the normal group and the sham operation group, the behavioral scores of each group were slightly increased, and the difference was not statistically significant (P>0.05).Compared with the model group, the content of D-Ser and the protein expression of NR1, NR2A and NR2B in the brain tissue of the model+D-Ser group were significantly increased (P<0.05);The protein expression of NR1, NR2A and NR2B decreased in EA pericardium meridian group (P<0.05);Compared with the model+ D-Ser group, the D-Ser content and the protein expression of NR1, NR2A and NR2B in the EA pericardium meridian+D-Ser group were decreased (P<0.05).

文摘Objective Alzheimer’s disease(AD)has become a significant global concern,but effective drugs able to slow down AD progression is still lacked.Electroacupuncture(EA)has been demonstrated to ameliorate cognitive impairment in individuals with AD.However,the underlying mechanisms remains poorly understood.This study aimed at examining the neuroprotective properties of EA and its potential mechanism of action against AD.Methods APP/PS1 transgenic mice were employed to evaluate the protective effects of EA on Shenshu(BL 23)and Baihui(GV 20).Chemogenetic manipulation was used to activate or inhibit serotonergic neurons within the dorsal raphe nucleus(DRN).Learning and memory abilities were assessed by the novel object recognition and Morris water maze tests.Golgi staining,western blot,and immunostaining were utilized to determine EA-induced neuroprotection.Results EA at Shenshu(BL 23)and Baihui(GV 20)effectively ameliorated learning and memory impairments in APP/PS1 mice.EA attenuated dendritic spine loss,increased the expression levels of PSD95,synaptophysin,and brain-derived neurotrophic factor in hippocampus.Activation of serotonergic neurons within the DRN can ameliorate cognitive deficits in AD by activating glutamatergic neurons mediated by 5-HT1B.Chemogenetic inhibition of serotonergic neurons in the DRN reversed the effects of EA on synaptic plasticity and memory.Conclusion EA can alleviate cognitive dysfunction in APP/PS1 mice by activating serotonergic neurons in the DRN.Further study is necessary to better understand how the serotonergic neurons-related neural circuits involves in EA-induced memory improvement in AD.
文摘Objective:To evaluate the effectiveness and safety of electroacupuncture in conjunction with additional medications in providing analgesia and stabilizing hemodynamic parameters during total thyroidectomy.Methods:This randomized controlled trial included 100 patients who underwent a total thyroidectomy between October 2022 and October 2023 at the Vietnam National Hospital of Acupuncture.The patients were randomized into two groups.The electroacupuncture analgesia(EA)group received EA stimulation at five acupuncture points:Hegu(LI 4),Neiguan(PC 6),Shuitu(ST 10),Quepen(ST 12),and Yifeng(SJ 17),while the control group received a bilateral superficial cervical plexus block.Primary outcomes included the level of analgesia and perioperative vital signs in both groups.Additionally,pain thresholds and serum b-endorphin levels were measured before and after electroacupuncture in the EA group.Results:Complete analgesia(Level A)was attained in 86%and 76%of the patients in the EA and control groups,respectively,with no significant difference between the two groups(P=1.00).In the EA group,the mean pain threshold after receiving EA doubled(648.7(77.4)g/s vs.305.3(45.3)g/s,P<.001),and the mean serum b-endorphin level increased by approximately 13.5 pg/mL(P<.001).All patients remained hemodynamically stable throughout the surgery.Conclusion:EA,in conjunction with additional medications that stimulate five acupuncture points,LI 4,PC 6,ST 10,ST 12,and SJ 17,was well tolerated and effectively maintained a suitable level of analgesia and hemodynamic stability during total thyroidectomy.

文摘Objective:Electroacupuncture(EA)is an alternative treatment option for pain.Different frequencies of EA have different painrelieving effects;however,the central mechanism is still not well understood.Methods:The Fos2A-iCreER(TRAP):Ai9 mice were divided into three groups(sham,2 Hz,and 100 Hz).The mice were intraperitoneally injected with 4-hydroxytamoxifen(4-OHT)immediately after EA at Zusanli(ST36)for 30 min to record the activated neurons.One week later,the mice were sacrificed,and the number of TRAP-treated neurons activated by EA in the thalamus,amygdala,cortex,and hypothalamus was determined.Results:In the cortex,2 Hz EA activated more TRAP-treated neurons than 100 Hz EA did in the cingulate cortex area 1(Cg1)and primary somatosensory cortex(S1),and 2 and 100 Hz EAs did not differ from sham EA.TRAP-treated neurons activated by 2 Hz EA were upregulated in the insular cortex(IC)and secondary somatosensory cortex(S2)compared with those activated by 100 Hz and sham EA.In the thalamus,the number of TRAP-treated neurons activated by 2 Hz EA was elevated in the paraventricular thalamic nucleus(PV)compared with those activated by sham EA.In the ventrolateral thalamic nucleus(VL),the number of TRAPtreated neurons activated by 2 Hz EA was significantly upregulated compared with those activated by 100 Hz EA,and sham EA showed no difference compared with 2 or 100 Hz EA.TRAP-treated neurons were more frequently activated in the ventral posterolateral thalamic nucleus(VPL)by 2 Hz EA than by 100 Hz or sham EA.Conclusions:Low-frequency EA ST36 effectively activates neurons in the Cg1,S1,S2,IC,VPL,PV,and VL.The enhanced excitability of the aforementioned nuclei induced by low-frequency EA may be related to its superior efficacy in the treatment of neuropathological pain.

文摘Sepsis is a life-threatening inflammatory syndrome with high morbidity and mortality rates.However,options for sepsis are still limited to general treatment in intensive care units(ICUs),and effective therapies that improve sepsis survival are required.Immune disturbances play a vital role in the pathology of sepsis and are associated with protracted inflammation,susceptibility to infections,and death.Therefore,many investigators have focused on the potential benefits of immunomodulation therapy for sepsis.Electroacupuncture(EA)has been practiced in clinics for many years and has shown advantages in treating infectious diseases.Over the last few decades,our understanding of the efficacy and mechanisms of EA in sepsis has undergone considerable developments.We searched the literature regarding“CNKI,Wan Fang Data,VIP Database,PubMed,and Ingenta Connect”from 2010 to 2023,using the keywords“sepsis”“septic”and“electroacupuncture”and 336 sources were searched.Finally,we included 82 studies that targeted the immune system to determine EA’s anti-inflammatory and immunomodulatory effects on sepsis.In this review,we found that EA has clinical benefits in relieving septic inflammation,improving immune function,and attenuating related multi-organ injury through several mechanisms,such as activation of the cholinergic anti-inflammatory pathway(CAP),vagaladrenal axis,inhibition of the nuclear factor Kappa-B(NF-κB)signaling pathway,signal transducers and activators of transcription(STAT)signaling pathway,and improvement of immune cell function.Therefore,EA may be a promising complementary therapy for sepsis treatment.We also expect these data will contribute to further studies on EA in sepsis.

文摘Background: To explore the effects of electroacupuncture on cardiac function and myocardial fibrosis in rat models of heart failure, and to elucidate the underlying mechanism of electroacupuncture in heart failure treatment. Methods: Healthy male Sprague-Dawley rats were allocated into three groups: Sham group, Model group, and electroacupuncture (Model + EA) group, with each group comprising 8 rats. The model underwent a procedure involving the ligation of the left anterior descending coronary artery to induce a model of heart failure. The Model + EA group was used for 7 consecutive days for electroacupuncture of bilateral Shenmen (HT7) and Tongli (HT5), once a day for 30 min each time. Left ventricular parameters in rats were assessed using a small-animal ultrasound machine to analyze changes in left ventricular end-diastolic volume, left ventricular end-systolic volume, left ventricular ejection fraction, and left ventricular fractional shortening. Serum interleukin-1β (IL-1β), cardiac troponin (cTn), and N-terminal brain natriuretic peptide precursor levels were measured using ELISA. Histopathological changes in rat myocardium were observed through HE staining, while collagen deposition in rat myocardial tissue was assessed using the Masson staining method. Picro sirius red staining, immunohistochemical staining, and RT-qPCR were utilized to distinguish between the various types of collagen deposition. The expression level of TGF-β1 and SMAD2/3/4/7 mRNA in rat myocardial tissues was determined using RT-qPCR. Additionally, western blot analysis was conducted to assess the protein expression levels of TGF-β1, SMAD3/7, and p-SMAD3 in rat myocardial tissues. Results: Compared with the Sham group, the left ventricular ejection fraction and left ventricular fractional shortening values of the Model group were significantly decreased (P < 0.01);the left ventricular end-diastolic volume and left ventricular end-systolic volume values were remarkably increased (P < 0.01);serum N-terminal brain natriuretic peptide precursor content was increased (P < 0.01);serum IL-1β and cTn levels were increased (P < 0.01);myocardial collagen volume fraction were increased (P < 0.01);and those of the expression of TGF-β1 and SMAD2/3/4 mRNA was increased (P < 0.01);the expression of SMAD7 mRNA was decreased (P < 0.01);the protein expression levels of TGF-β1, SMAD3, and p-Smad3 were increased (P < 0.01);the protein expression level of SMAD7 was decreased (P < 0.01) in the Model group. Compared to the Model group, the expression levels of the proteins TGF-β1, SMAD3, and p-Smad3 in myocardial tissue were found to be decreased (P < 0.01), and the expression level of the protein SMAD7 was found to be increased (P < 0.01) in the Model + EA group;the collagen volume fraction and deposition of type Ⅰ /Ⅲ collagen were decreased (P < 0.01) in the Model + EA group. Conclusion: Electroacupuncture alleviates myocardial fibrosis in rats with heart failure, and this effect is likely due to attributed to the modulation of the TGF-β1/Smads signaling pathway, which helps reduce collagen deposition in the extracellular matrix.
文摘BACKGROUND The rotator cuff is located below the acromion and deltoid muscles and comprises multiple tendons that wrap around the humeral head,maintaining shoulder joint stability.AIM To explore the effect of electroacupuncture combined with rehabilitation techniques on shoulder function in patients with rotator cuff injuries.METHODS We selected 97 patients with rotator cuff injuries treated in the People's Hospital of Yuhuan from February 2020 to May 2023.Patients were grouped using the envelope method.RESULTS After treatment,the study group’s treatment effective rate was 94.90%(46/49 patients),significantly higher than that in the control group(79.17%,38/48 cases;P<0.05).Before treatment,there was no difference in Constant Murley Score(CMS)scores,shoulder mobility,or 36-Item Short Form Health Survey(SF-36)scale scores(P>0.05).Compared with those before treatment,the CMS scores(including pain,daily living ability,shoulder mobility,and muscle strength),all aspects of shoulder mobility(forward flexion,posterior extension,external rotation,internal rotation),and SF-36 scale scores(including physiological,psychological,emotional,physical,vitality,and health status)were higher in both groups after treatment and significantly higher in the study group(P<0.05).There was no difference in the occurrence of complications between the two treatment groups(P>0.05).CONCLUSION Electroacupuncture combined with rehabilitation techniques has a good treatment effect on patients with rotator cuff injuries,helps accelerate the recovery of shoulder function,improves the quality of life,and is highly safe.

文摘Objective:To investigate the mechanism of JAK2/STAT3/SOCS1 signaling pathway in electroacupuncture of different acupoints on acute colitis rats.Methods:36 SPF SD rats were randomly divided into 6 groups,with 6 rats in each group.The rat model of acute colitis was prepared by enema with glacial acetic acid solution.After the model was established,electroacupuncture was given to each acupoint group,with density wave,frequency 2Hz-50 Hz,intensity 2 mA,muscle tremor as the degree 20 min/time,1 time/day,for 3 consecutive days.Observe the general condition of rats;the pathological changes of colonic mucosa in rats were observed by HE method.The contents of serum interleukin-4(IL-4)and interleukin-8(IL-8)were detected by ELISA.Western blot and RT-PCR were used to detect the expression of JAK2,STAT3,SOCS1 protein and mRNA in rat colon tissue.Results:In contrast to the normal group,the overall condition of the model group was worse,the colonic mucosa was severely damaged,even necrotic,and the ulcer surface was obvious.The content of IL-4 in serum was obviously reduced,and the content of IL-8 was obviously go up(P<0.01).The protein content of JAK2,STAT3 and the expression of JAK2,STAT3 mRNA in colon tissue of rats were obviously go up,while the protein content of SOCS1 and the expression of SOCS1 mRNA were obviously reduced(P<0.01).In contrast to the model group,the general condition of rats in each acupoint group was significantly improved,the damage and necrosis of colonic mucosa and ulcer surface were obviously alleviated,the content of IL-4 in serum was obviously go up,and the content of IL-8 was significantly decreased(P<0.01).The protein content of JAK2,STAT3 and the expression of JAK2,STAT3 mRNA in colon tissue of rats were obviously reduced,while the protein content of SOCS1 and the expression of SOCS1 mRNA were obviously go up(P<0.05,P<0.01).Comparison of different acupoint groups,the colonic mucosal injury in the Zusanli group was significantly reduced,the content of serum IL-4 was significantly increased,and the content of IL-8 was significantly decreased(P<0.05,P<0.01).The protein content and mRNA expression of JAK2 and STAT3 in colon tissue were significantly down-regulated,while the protein content and mRNA expression of SOCS1 were significantly go up(P<0.05,P<0.01).Conclusion:Electroacupuncture at each acupoint can improve the damage of colonic mucosa and reduce the inflammatory response.The therapeutic effect of Zusanli(ST36)is better than that of Tianshu(ST25),Dachangshu(BL25)and Shangjuxu(ST37).The mechanism may be related to the regulation of JAK2/STAT3/SOCS1 signaling pathway related proteins and inflammatory cytokines IL-4 and IL-8.
文摘[Objectives]To investigate the evidence-based effect of electroacupuncture on the post stroke inflammatory response and elucidate its potential molecular mechanisms.[Methods]Asystematic electronic search of the Medline,PubMed,and Web of Science databases was initially performed up to June 2024.The risk of bias of the included studies was evaluated using RevMan5.4 software,in accordance with the guidelines set forth in the Cochrane Handbook for Systematic Revieus.The random-effects model or fixed-effects models was employed to esti-mate the standardized mean difference(SMD).[Results]A total of 15 studies,comprising a total of 182 rats or mice,were included in this review.The pooled analysis of these trials showed a statistically significant reduction in the level of TNF-α(12 studies,SMD=-2.38,[95%CI,-2.86 to-1.90],P<0.00001,I^(2)=49),and IL-1β(11studies,SMD=-2.41,[95%CI,-3.32 to-1.50],P<0.00001,I^(2)=57).Additionally,the compiled data demonstrated a notable and statistically significant elevation in the IL-10 level(6 studies,SMD=1.56,[95%CI,0.42 to 2.70],P=0.008,I^(2)=68).[Conclusions]The findings of this systematic review and meta-analysis dem-onstrate that electroacupuncture stimulation has the potential to regulate the inflammatoryresponses after stroke.
文摘[Objectives]The aim of this study was to investigate the effect of electroacupuncture on infarct size in cerebral ischemic stroke.[Methods]A systematic electronic search was conducted up to June 1,2024.TTC staining was used to evaluate the infarct size.Standard mean differences(SMD)with a95%confidence interval(CI)were calculated to assess the two intervention methods.The heterogeneity of the included studies was also tested.Two analyses with subgroups were planned:intervention start time(before MCAOversus after MCAO).waveform(continuous wave versus disperse wave).[Results]Forty-one studies with a total of 502 rats or mice were included in this review.The pooled analysis of these trials showed a significant positive effect of electroacupuncture on the infarct size(SMD=-2.65,P<0.0001,Z=12.55).Subgroup analysis results indicated that electroacupuncture intervention before MCAO surgery(16 studies,SMD=-2.73,P<0.00001,Z=10.60)could more significantly reduce infarct size than that after MCAO surgery(25studies,SMD=-2.61,P<0.00001,Z=8.20).Additionally,disperse waves(31 studies,SMD=-2.46,P<0.00001,Z=11.08)were more effective in reducing infarct area than continuous waves(10 studies,SMD=-3.38,P<0.00001,Z=6.12).[Conclusions]This review provided sufficient evidence that electroacupuncture before MCAO surgery with disperse waves was more effective in reducing infarct area than after MCAO surgery and continu-ous waves.

文摘Background:Ischemia-reperfusion can worsen myocardial damage and increase the risk of death.Studies have revealed that ischemic preconditioning provides the best endogenous protection against myocardial ischemia-reperfusion injury(MIRI),and the principle of electroacupuncture(EA)preconditioning is comparable to that of myocardial ischemic preconditioning adaption.Our earlier research demonstrated that EA pretreatment inhibits the expression of calmodulin-dependent protein kinase IIδ(CaMKIIδ),sodium/calcium exchanger 1(NCX1),and cyclophilin D,hence providing protection against MIRI.However,the exact mechanism is still unknown.The expression of NCX1 mRNA is directly regulated by microRNA-214(miR-214).Moreover,it suppresses the levels of CaMKIIδand cyclophilin D.Whether these variables contribute to EA preconditioning to improve MIRI needs to be investigated,though.This study aimed to preliminarily determine whether EA pretreatment ameliorates MIRI by modulating the miR-214-3p/NCX1 axis.Methods:We used a rat MIRI model to investigate the effect of EA pretreatment on MIRI and the expression of miR-214-3p.In addition,adenovirus injection inhibited miR-214-3p expression in the rat MIRI model,and the influence of EA pretreatment towards MIRI was observed in the context of blocked miR-214-3p expression.Both the myocardial histological abnormalities and the alterations in the ST segment of the rat electrocardiogram were analyzed.NCX1 mRNA,cyclophilin D,and CaMKIIδexpression levels were also analyzed.Results:EA pretreatment improved MIRI.In rats with MIRI,EA administration increased miR-214-3p expression while decreasing NCX1 mRNA,cyclophilin D,and CaMKIIδproteins in cardiac tissues.The beneficial effect of EA pretreatment against MIRI was reversed,coupled with elevated levels of NCX1 mRNA,cyclophilin D,and CaMKIIδprotein expression,when an adenovirus injection disrupted the expression of miR-214-3p.Conclusions:Our findings preliminarily show that EA pretreatment inhibits the expression of NCX1 mRNA,cyclophilin D,and CaMKIIδproteins via miR-214-3p,hence exerting MIRI protection.

文摘OBJECTIVE To investigate whether electroacupuncture(EA)ameliorates abnormal trigeminal neuralgia(TN)orofacial pain and anxiety-like behavior by altering synaptic plasticity in the hippocampus CA1.METHODS A mouse infraorbital nerve transection model(pTION)of neuropathic pain was established,and EA or sham EA was used to treat ipsilateral acu⁃puncture points(GV20-Baihui and ST7-Xia⁃guan).Golgi-Cox staining and transmission elec⁃tron microscopy(TEM)were administrated to observe the changes of synaptic plasticity in the hippocampus CA1.RESULTS Stable and persistent orofacial allodynia and anxiety-like behav⁃iors induced by pT-ION were related to changes in hippocampal synaptic plasticity.Golgi stain⁃ings showed a decrease in the density of dendritic spines,especially mushroom-type dendritic spines,in hippocampal CA1 neurons of pT-ION mice.TEM results showed that the density of synapses,membrane thickness of the postsynaptic density,and length of the synaptic active zone were decreased,whereas the width of the synaptic cleft was increased in pTION mice.EA attenu⁃ated pT-ION-induced orofacial allodynia and anx⁃iety-like behaviors and effectively reversed the abnormal changes in dendritic spines and syn⁃apse of the hippocampal CA1 region.CONCLU⁃SION EA modulates synaptic plasticity of hippo⁃campal CA1 neurons,and reduces abnormal oro⁃facial pain and anxiety-like behavior,providing evidence for a TN treatment strategy.

文摘Objective:To compare the effects of electroacupuncture(EA)and moxibustion at Zusanli(ST 36)on the lung phenotype of rat offspring exposed to nicotine during the perinatal period.Methods:Pregnant Sprague-Dawley rats were randomly divided into 4 groups:the control group(saline only),the model group(nicotine only),the EA group(nicotine+EA at ST 36 acupoints bilaterally),and the moxibustion group(nicotine+moxibustion at ST 36 acupoints bilaterally).n=6 rats per group.On postnatal day 21,the body weight,lung weight,and pulmonary function were determined and lung morphometry was performed.Peroxisome proliferator-activated receptor gamma andβ-catenin levels in the lung tissue of offspring were also determined.Results:Perinatal nicotine exposure(PNE)results in decreased body and lung weights of offspring rats,abnormal lung tissue morphology,and significantly altered pulmonary function,showing an increase in total airway resistance and a decrease in tidal volume,minute ventilation,total airway compliance,and peak expiratory flow.Bilateral EA at ST 36 acupoints could block all of these perinatal nicotine-induced effects.Although moxibustion also had protective effects in nicotine-induced offspring lungs,some of these effects did not reach statistical significance,e.g.,protection against the upregulation ofβ-catenin,the downregulation of PPARγsignaling,and the increase in peak expiratory flow.Conclusion:Maternal EA at ST 36 blocked the PNE-induced changes in key developmental signaling pathways,prevented the PNE-induced changes in lung morphology,and protected pulmonary function.Moxibustion at ST 36 showed similar but weaker protective effects against the PNE-induced changes in the exposed offspring.It is important to note that the mechanism underlying the protective effects of moxibustion at ST 36 may be different from those of EA at ST 36,and further research is needed to understand these differences.

文摘Objective :To observe the effect of electroacupuncture at pericardium meridian on neurological deficit, D-serine ( D-Ser ) content and NMDAR expression in ischemic brain tissue of rats with middle cerebral artery occlusion ( MCAO ). Methods:A total of 36 SD rats were randomly divided into normal group, sham operation group, model group, EA pericardium meridian group, model+D-Ser group,and EA pericardium meridian+D-Ser group. The MCAO model was prepared by Zea Longa method. The model+D-Ser group and the EA pericardium meridian+D-Ser group were given exogenous D-Ser reagent(160 mg/kg i.p.) 30 minutes after the success of the insertion of the suture. EA pericardium meridian group and EA pericardium meridian+D-Ser group were treated with electroacupuncture for 30 min on the next day. The remaining groups were only bound for 30 min.Behavioral evaluation was performed at 6 h after successful modeling and 2 d after intervention, and then the rats were sacrificed. The content of D-Ser in ischemic brain tissue was measured by liquid chromatography tandem mass spectrometry, and the protein expression of NR1, NR2A and NR2B was detected by Western Blot. Results : Before treatment, compared with the normal group and the sham operation group, the behavioral scores of each group increased after modeling (P<0.05 );Compared with the model group, the behavioral scores of the model+D-Ser group and the EA pericardium meridian+D-Ser group were increased (P<0.05).After treatment, compared with the model group, there was no significant difference in the EA pericardium meridian group (P>0.05),The behavioral scores of the model+D-Ser group and the EA pericardium meridian+D-Ser group were still increased (P<0.05);Compared with the model+D-Ser group, the behavioral score of the EA pericardium meridian+D-Ser group was not statistically significant (P>0.05).Comparison before and after treatment in the group,except for the normal group and the sham operation group, the behavioral scores of each group were slightly increased, and the difference was not statistically significant (P>0.05).Compared with the model group, the content of D-Ser and the protein expression of NR1, NR2A and NR2B in the brain tissue of the model+D-Ser group were significantly increased (P<0.05);The protein expression of NR1, NR2A and NR2B decreased in EA pericardium meridian group (P<0.05);Compared with the model+ D-Ser group, the D-Ser content and the protein expression of NR1, NR2A and NR2B in the EA pericardium meridian+D-Ser group were decreased (P<0.05). Conclusion : EA at pericardium meridian points can reduce the D-Ser content in brain tissue of rats with acute MCAO, regulate the decrease of NR1, NR2A and NR2B protein expression, inhibit the NMDA receptor activity, and play a neuroprotective role.
