Because an immune response imbalance could be seen in COPD, we hypothesize that electroacupuncture （EA） may play a role in regulating inflammatory cytokines and contribute to lung protection in a rat model of smoke-induced COPD. METHODS： A COPD model using male Sprague-Dawley rats exposed to cigarette smoke was established. The rats were randomly divided into four groups （control, sham, COPD, and COPD plus EA）, and COPD model was evaluated by measuring pulmonary pathological changes and lung function. EA was applied to the acupuncture point Zusanli （ST36） for 30 min/d for 14 d in sham and COPD rats. Bronchoalveolar lavage fluid （BALF） was used to measure levels of tumor necrosis factor-a （TNF-a）, interleukin-113 （IL-113）, and malonaldehyde （MDA）. RESULTS： Compared with the control rats, COPD rats had significant changes in lung resistance （R,） and lung compliance （C,） （both P〈0.01）, bronchi and bronchiole airway obstruction （P〈0.01）, and levels of MDA, TNF-α, and IL-1β（P〈0.01）. There were no significant differences between the control and the sham groups. Compared with the COPD rats, the COPD plus EA rats had decreased R, and increased CL （both P〈0.05）, and reduced bronchi and bronchiole airway obstruction （P〈0.05, P〈0.01, respectively）, while levels of TNF-α, IL-1β, and MDA in BALF were lowered （P〈0.05 and P〈0.01, respectively）. However, TNF-α and IL-1β levels of the EA group rats remained higher than those of the control group （P〈0.05）. CONCLUSION： EA at ST36 can reduce lung injury in a COPD rat model, and beneficial effects may be related to down-regulation of inflammatory cytokines. The anti-inflammatory and antioxidant effects may prolong the clinical benefit of EA.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

A solution containing ethanol and 2,4,6-trinitrobenzenesulfonic acid (TNBS) was instilled into the distal colon in the rat (at a dose of 100 mg/kg) to set up UC rat model. Rats in wakefulness state of UC+ST36 group were stimulated at ST36 by EA once a day, while those of UC+nonacupoint group were done at 0.5 cm beside ST36. After 10d treatment, all rats were sacrificed simultaneously. Colon musocal inflammation and damage were assessed by measuring colon mass, morphologic damage score, colonic myeloperoxidase enzyme (MPO) activity, serum TNF-α and colonic TNF-α mRNA level. Morphologic damage score was examined under stereomicroscope. Colonic MPO activity was measured by spectrophotometer method. Serum TNF-αconcentration was determined by radioimmunoassay (RIA).Colonic TNF-α mRNA expression level was analyzed by semiquantitative reverse transcription polymerase chain reaction (RT-PCR).RESULTS: Ratio of colonic mass/body mass (mC/mB) and activity of colonic MPO (μkat/g tissue) markedly increased (8.5±2.6 vs 2.5±0.4; 145±25 vs 24±8, P＜0.01 vs normal control group). Compared with normal control rats, serum TNF-α and colonic TNF-α mRNA level in UC control group were increased 2.5 fold (2 278±170 vs 894±248, P＜0.01)and 4.3 fold (0.98±0.11 vs 0.23±0.11, P＜0.01)respectively. After EA at ST36, mc/mB and MPO activity were reduced significantly (5.3±2.0 vs 8.5±2.6; 104±36 vs145±25, P＜0.01, 0.05) compared with those of UC control group. Serum TNF-α and colonic TNF-α mRNA level were inhibited by EA stimulation at ST36 (P＜0.01). The inhibitory rate was 16 % and 44 % respectively.Morphologic damage score was also increased markedly in rat with UC (P＜0.01), whereas it was decreased by EA at ST36 (P＜0.05). There was no significant difference between UC control group and UC+EA at non-acupoint (P＞0.05). Furthermore, these parameters were highly correlated with each other (P＜0.01).CONCLUSION: Serum TNF-α concentration and colonic TNF-α mRNA expression level are increased significantly in UC rats in correlation with the severity of disease. It indicates that TNF-α is closely involved in the immune abnormalities and inflammatory responses in UC. EA at ST36 has therapeutic effect on UC by downregulating serum TNF-r and colonic TNF-r mRNA expression. High levels of TNF-αand its corresponding mRNA expression seem to be implicated in the pathogenesis of UC.展开更多

However, the signaling pathway underlying this effect remains unclear. Rats were intragastrically administered absolute alcohol, causing obvious lesion of the gastric mucosa. Following pre-moxibustion at Zusanfi （ST36） for 8 days, the ulcer index decreased to different degrees. The results of an enzyme linked immunosorbent assay and western blotting showed significant upregulation of heat shock protein 70 expression in the gastric mucosa and serum. None out of transection of the spinal cord, damage to the nucleus of the solitary tract, neurotomy of the vagal nerve and neurotomy of the common peroneal nerve affected the decrease in ulcer index or the increase in heat shock protein 70 expression in serum after pre-moxibustion at Zusanfi, and heat shock protein 70 expression was obviously decreased in the gastric mucosa. These findings suggest that pre-moxibustion at Zusanfi can protect the gastric mucosa against lesioning, and that the mechanism underlying this effect involves its induction of heat shock protein 70 expression. Neural pathways participate in the regulatory effects of moxibustion on heat shock protein 70 expression in the gastric mucosa.展开更多

For the sham group, the rats were opened abdominal cavity for 3 h and 20 min and their abdominal cavities were covered with wet gauze avoiding drying and kept on the thermostat at 37 0 C. For the ischemia/reperfusion（I/R） group,rats were anaesthetised and their abdominal cavities were opened to expose jejunum segments. The segment＇s collateral blood supply was restricted by bilateral ligation of the intestine. Next, one of the branches of a mesenteric artery was occluded with a thread for 20 min and then the thread was released after such ischemia conditions, keeping reperfusion for 3 h. For the ST36 ＋ I/R group, the electroacupuncture at ST36 was first performed, then the intestinal ischemia/reperfusion model was constructed. For the N ＋ I/R group, electroacupuncture at non ST36 acupoint, which is away from ST36 about 0.5 cm, and then the intestinal ischemia/reperfusion model was performed. Measurements of the levels of inflammatory markers tumour necrosis factor a（TNFa） and interleukin-1 beta（IL-1β）, cytochrome c（CYCS）, and the mitochondrial membrane pro-apoptotic protein（BAX）, anti-apoptotic protein Bcl-2 were performed.Results： Compared to I/R group, the intensity of cytoplasmic CYCS in intestinal tissues was significantly decreased in the ST 36 ＋ I/R group（1.65 vs. 0.18, p〈0.05）. Compared to N ＋ I/R group, the intensity of cytoplasmic CYCS in intestinal tissues was also dramatically declined in the ST 36 ＋ I/R group（1.37 vs. 0.18, p〈0.05）. The level of CYCS in mitochondria in rats in the ST 36 ＋ I/R group were appreciably increased than those of rats in the I/Rgroup（1.42 vs. 0.06, p〈0.05）, and CYCS in mitochondria was also largely expressed in ST36 ＋ I/R group than N ＋ I/R group（1.42 vs. 0.08, p〈0.05）. Bcl-2 was shown to be elevated in the ST 36 ＋ I/R group than I/R group（1.01 vs. 0.10） and N ＋ I/R group（1.01 vs. 0.09, all p〈0.05）, whereas BAX expression was greatly decreased in the ST36 ＋ I/R group than I/R group（0.11 vs.0.78） and N ＋ I/R group（0.11 vs. 0.87, all p〈0.05）.Conclusion： The results suggest the EA intervention has a protective effect upon mitochondria, preventing CYCS release and the subsequent activation of downstream apoptosis pathway. It is proposed that patients due to undergo gastrointestinal surgery get benefit from EA preconditioning at ST 36.展开更多

In the present study, weconducted a single-arm, open-label, pilot clinical trial to evaluate the prophylactic effects of stimulating the ST36acupoint through acupuncture and moxibustion in middle-aged and elderly participants. Of the 85 participantswho completed the first 2 months of acupuncture and moxibustion, 48 continued through the remaining 4 monthsto complete the full 6-month intervention. For 6 months acupuncture and moxibustion at ST36 significantlyreduced levels of low-density lipoprotein (LDL) and uric acid (UA) in individuals with initially abnormal LDLand UA values. The median LDL levels decreased from 4.46 mmol/L (IQR 4.32–4.71) to 3.97 mmol/L (IQR3.32–4.47) (P = 0.004) and the median UA levels decreased from 399.00 μmol/L (IQR 356.00–483.00) to 361.00μmol/L (IQR 323.00–421.00) (P = 0.003). Additionally, ST36 intervention led to marked reductions in the levels oflactic dehydrogenase (LDH) (266.50 U/L (IQR 257.50–282.25) to 235.50 U/L (IQR 215.50–244.75), P < 0.001) at 6months, and α-hydroxybutyrate dehydrogenase (α-HBDH) (195.50 U/L (IQR 190.25–212.00) to 181.00 U/L (IQR165.75–187.25), P = 0.017) at 2 months. Notably, ST36 acupuncture and moxibustion also showed positive effectson sleep quality, knee joint function, and bowel movement patterns, and there were no syncope, severe pain orother adverse reactions. These findings provide clinical evidence that ST36 acupoint stimulation confers holistichealth benefits for middle-aged and elderly populations, while maintaining an excellent safety profile.展开更多

Visual experimental evidence, as well as statistical parametric mapping (SPM), was gathered while puncturing the ST36 (Zusanli, right leg) acupoint.Results There was increased glycometabolism in the hypothalamus, head of the caudate nucleus, temporal lobe, the sinistral cerebellum, postcentral gyrus, and brain stem while the acupoint ST36 was being punctured. Conclusions Acupuncture on ST36 can lead to increase in glycometabolism in the vegetative nerve centers, which is correlated with gastric function. Visual experimental evidence of ST36 acupuncturing on functional gastrointestinal disorder was obtained in our study.展开更多

Interestingly, acupuncture at RN12+ST36 together yielded effects similar to that of acupuncture at RN12 alone(93.59±2.05)%,(54.52±7.12)%. 2) WDR neuron discharges induced by gastric distension were inhibited by acupuncture at RN12(194.56 ±18.79)%. However, acupuncture at ST36 induced a more significant inhibitory effect.Conclusion: Acupuncture at RN12 inhibits gastric motility by activation of the sympathetic reflex at the spinal level; acupuncture at ST36 promotes gastric motility by activation of the parasympathetic reflex at the supraspinal level, and acupuncture at RN12+ST36 produces a similar decrease in gastric motility as RN12 stimulation alone. Both acupoints decrease the effect of noxious gastric distention on WDR neuron activity, but paired RN12+ST36 stimulation does not significantly affect WDR neuron discharge.展开更多

文摘OBJECTIVE:To observe the effects of moxibustion at Zusanli(ST36)on rats with chronic fatigue syndrome(CFS)and to analyze the mechanisms of moxibustion through hippocampal Proteomics.METHODS:Male Sprague-Dawley(SD)rats were randomly divided into three groups:control group(CON),model group(MOD),and moxibustion group(MOX),with 12 rats in each group.The MOD and MOX groups underwent chronic multi-factor stress stimulation for 35 d to establish the CFS model.After modeling,the rats in the MOX group received mild moxibustion at Zusanli(ST36)(bilateral)for 10 minutes daily for 28 d.During the treatment period,rats in both the MOD and MOX groups continued modeling,while the CON group was kept under normal breeding conditions.The general condition of the rats was monitored,and behaviors were assessed using the Open Field Test(OFT),Exhaustion Treadmill Test,and Morris Water Maze(MWM).Hematoxylin and eosin(HE)staining and transmission electron microscopy(TEM)were employed to observe morphological changes in the hippocampus.Label-free Proteomics were utilized to identify differentially expressed proteins(DEPs)in the hippocampus,followed by bioinformatics analysis.The reliability of the Proteomics results was verified using Parallel Reaction Monitoring.RESULTS:A:Moxibustion at Zusanli(ST36)significantly reduced the general condition score of CFS rats,improved their behavioral performance in OFT,treadmill and MWM,and repaired the pathological and synaptic structural damage in the hippocampus.B:We identified DEPs by applying a fold change threshold of 1.2 and a significance level of P<0.05.In the comparison between the CON and the MOD,we identified a total of 72 DEPs(31 up-regulated and 41 down-regulated)associated with the development of CFS.In the comparison between the MOX and the MOD group,we identified a total of 103 DEPs(40 up-regulated and 63 down-regulated)related to the therapeutic effects of moxibustion.Gene Ontology(GO)enrichment analysis showed that CFS and moxibustion treatment were related to multiple biological processes,molecular functions,and cellular components.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis revealed that CFS pathogenesis was linked to base excision repair,steroid biosynthesis,and systemic lupus erythematosus,Furthermore,the treatment of CFS with moxibustion was relevant to terpenoid skeleton biosynthesis.C:Compared with the two comparison groups,we identified 16 potential biomarkers,noting that moxibustion reversed the upregulation of 14 DEPs and the down-regulation of 2 DEPs in CFS.These proteins are mainly associated with synaptic plasticity,ribosomal function,neurotransmitter secretion,glycine metabolism,and mitochondrial function.CONCLUSION:Moxibustion at Zusanli(ST36)is effective in treating CFS,the potential biomarkers identified by Proteomics confirm that the mechanisms of moxibustion involve multiple targets and pathways,which may be key to regulating the structural and functional damage in the hippocampus associated with CFS,highlighting their significant value for future research.

文摘OBJECTIVE： Improvement in lung function was reported after acupuncture treatment of chronic obstructive pulmonary disease （COPD）, but little is known about the underlying mechanisms. Because an immune response imbalance could be seen in COPD, we hypothesize that electroacupuncture （EA） may play a role in regulating inflammatory cytokines and contribute to lung protection in a rat model of smoke-induced COPD. METHODS： A COPD model using male Sprague-Dawley rats exposed to cigarette smoke was established. The rats were randomly divided into four groups （control, sham, COPD, and COPD plus EA）, and COPD model was evaluated by measuring pulmonary pathological changes and lung function. EA was applied to the acupuncture point Zusanli （ST36） for 30 min/d for 14 d in sham and COPD rats. Bronchoalveolar lavage fluid （BALF） was used to measure levels of tumor necrosis factor-a （TNF-a）, interleukin-113 （IL-113）, and malonaldehyde （MDA）. RESULTS： Compared with the control rats, COPD rats had significant changes in lung resistance （R,） and lung compliance （C,） （both P〈0.01）, bronchi and bronchiole airway obstruction （P〈0.01）, and levels of MDA, TNF-α, and IL-1β（P〈0.01）. There were no significant differences between the control and the sham groups. Compared with the COPD rats, the COPD plus EA rats had decreased R, and increased CL （both P〈0.05）, and reduced bronchi and bronchiole airway obstruction （P〈0.05, P〈0.01, respectively）, while levels of TNF-α, IL-1β, and MDA in BALF were lowered （P〈0.05 and P〈0.01, respectively）. However, TNF-α and IL-1β levels of the EA group rats remained higher than those of the control group （P〈0.05）. CONCLUSION： EA at ST36 can reduce lung injury in a COPD rat model, and beneficial effects may be related to down-regulation of inflammatory cytokines. The anti-inflammatory and antioxidant effects may prolong the clinical benefit of EA.

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AIM: To investigate the regulatory effect of electroacupuncture (EA) at Zusanli (ST36) on tumor necrosis factor-alpha (TNFα) in rats with ulcerative colitis (UC), and further elucidate the therapeutic mechanism of EA on UC.METHODS: Thirty-two male Sprague-Dawley (SD) rats were randomly divided into four groups (n=-8): normal control group, UC control group, UC+ST36 group and UC+nonacupoint group. A solution containing ethanol and 2,4,6-trinitrobenzenesulfonic acid (TNBS) was instilled into the distal colon in the rat (at a dose of 100 mg/kg) to set up UC rat model. Rats in wakefulness state of UC+ST36 group were stimulated at ST36 by EA once a day, while those of UC+nonacupoint group were done at 0.5 cm beside ST36. After 10d treatment, all rats were sacrificed simultaneously. Colon musocal inflammation and damage were assessed by measuring colon mass, morphologic damage score, colonic myeloperoxidase enzyme (MPO) activity, serum TNF-α and colonic TNF-α mRNA level. Morphologic damage score was examined under stereomicroscope. Colonic MPO activity was measured by spectrophotometer method. Serum TNF-αconcentration was determined by radioimmunoassay (RIA).Colonic TNF-α mRNA expression level was analyzed by semiquantitative reverse transcription polymerase chain reaction (RT-PCR).RESULTS: Ratio of colonic mass/body mass (mC/mB) and activity of colonic MPO (μkat/g tissue) markedly increased (8.5±2.6 vs 2.5±0.4; 145±25 vs 24±8, P＜0.01 vs normal control group). Compared with normal control rats, serum TNF-α and colonic TNF-α mRNA level in UC control group were increased 2.5 fold (2 278±170 vs 894±248, P＜0.01)and 4.3 fold (0.98±0.11 vs 0.23±0.11, P＜0.01)respectively. After EA at ST36, mc/mB and MPO activity were reduced significantly (5.3±2.0 vs 8.5±2.6; 104±36 vs145±25, P＜0.01, 0.05) compared with those of UC control group. Serum TNF-α and colonic TNF-α mRNA level were inhibited by EA stimulation at ST36 (P＜0.01). The inhibitory rate was 16 % and 44 % respectively.Morphologic damage score was also increased markedly in rat with UC (P＜0.01), whereas it was decreased by EA at ST36 (P＜0.05). There was no significant difference between UC control group and UC+EA at non-acupoint (P＞0.05). Furthermore, these parameters were highly correlated with each other (P＜0.01).CONCLUSION: Serum TNF-α concentration and colonic TNF-α mRNA expression level are increased significantly in UC rats in correlation with the severity of disease. It indicates that TNF-α is closely involved in the immune abnormalities and inflammatory responses in UC. EA at ST36 has therapeutic effect on UC by downregulating serum TNF-r and colonic TNF-r mRNA expression. High levels of TNF-αand its corresponding mRNA expression seem to be implicated in the pathogenesis of UC.

文摘Studies have shown that pre-moxibustion protects the gastric mucosa by up-regulating the expression of heat shock protein 70. However, the signaling pathway underlying this effect remains unclear. Rats were intragastrically administered absolute alcohol, causing obvious lesion of the gastric mucosa. Following pre-moxibustion at Zusanfi （ST36） for 8 days, the ulcer index decreased to different degrees. The results of an enzyme linked immunosorbent assay and western blotting showed significant upregulation of heat shock protein 70 expression in the gastric mucosa and serum. None out of transection of the spinal cord, damage to the nucleus of the solitary tract, neurotomy of the vagal nerve and neurotomy of the common peroneal nerve affected the decrease in ulcer index or the increase in heat shock protein 70 expression in serum after pre-moxibustion at Zusanfi, and heat shock protein 70 expression was obviously decreased in the gastric mucosa. These findings suggest that pre-moxibustion at Zusanfi can protect the gastric mucosa against lesioning, and that the mechanism underlying this effect involves its induction of heat shock protein 70 expression. Neural pathways participate in the regulatory effects of moxibustion on heat shock protein 70 expression in the gastric mucosa.

文摘Objective:To explore the differences in the central response after acupuncture and moxibusbution at Zusanli(足三里ST36) in treatment of functional dyspepsia(FD) based on the analysis of fractional amplitude of low frequency fluctuation(fALFF) of resting-state functional magnetic resonance imaging(rfMRI).Methods:A total of 60 patients with FD were randomized into an acupuncture group and a moxibustion group,30 cases in each one.In the acupuncture group,acupuncture was applied to bilateral ST36.In the moxibustion group,moxibustion was exerted at bilateral ST36.The treatment was given once a day,5 times a week,totally for 4 weeks in each group,including 20 treatments with acupuncture or moxibustion.Separately,before and at the end of treatment,rfMRI scanning was conducted in two groups.Using data processing assistant for resting-state fMRI(DPARSF) software and MATLAB data platform,rfMRI data were collected for preprocessing and fALFF analysis.Results:Compared with the data before treatment,after treated with acupuncture at ST36 in FD patients,fALFF value was reduced in the right superior frontal gyrus,left superior frontal gyrus,left inferior frontal gyrus,right cuneus,left precuneus,right middle occipital gyrus,left middle occipital gyrus,etc.,and it was increased in the left parahippocampus,right parahippocampus,left cerebellum,etc(all P <0.01).After treated with moxibustion,the remarkable increase of fALFF was not discovered in brain areas,but fALFF decreased significantly in the left superior parietal gyrus(P <0.01).Compared with moxibustion at ST36,after acupuncture at ST36 in FD patients,the increase of fALFF appeared in the right putamen and the decrease of it occurred in the middle occipital gyrus,indicating the statistical significance(both P <0.05).Conclusion:The differences in central function responses are induced in treamtent with acupuncture and moxibustion,which is probably related to the resting-state default network associated with targeted regulation and ventral attention of brain areas in functional dyspepsia.

文摘OBJECTIVE:To investigate the mechanisms behind the effects of acupuncture in Traditional Chinese Medicine,we delved into the adenosine triphosphate/peripheral purinergic P2X receptor 3(ATP/P2X3)receptor signaling system as an indicator of the body's energy state,commonly referred to as"Qi".METHODS:The tail-flick test was utilized to explore the impact of acupuncture on pain tolerance threshold(PTT)in mice,while also assessing adenosine(ADO)levels and adenylate energy charge(EC)at Zusanli(ST36).The study further investigated the dose-dependent effects of acupuncture on PTT and ADO levels at Zusanli(ST36).To shed light on the underlying mechanisms of acupuncture's effects,the study examined the impact of ATP,a P2X3 receptor antagonist,and adenosine disodium on PTT following acupuncture administration.RESULTS:Acupuncture at Zusanli(ST36)led to significant improvements in PTT in mice,with the most effective interventions being twirling for 2 min and needle retention for 28 min.These interventions also resulted in significant increases in ATP levels.The effects of acupuncture were further augmented by administration of different doses of ATP at Zusanli(ST36),and pretreatment with a P2X3 receptor antagonist decreased PTT.Adenylate EC peaked at 30 min after intraperitoneal injection of ATP,and pretreatment with various doses of i.p.ATP 30 min prior to acupuncture increased PTT in a dose-dependent manner.Additionally,pretreatment with an i.p.or intramuscular injection of adenosine disodium enhanced the effects of acupuncture.CONCLUSION:This research provides compelling evidence that ATP is involved in the regulation of PTT through acupuncture,revealing new avenues for achieving enhanced clinical outcomes.

文摘Objective： The study explored the effect of applying electroacupuncture（EA） preconditioning at ST 36 on mitochondria in rats with intestinal ischemia/reperfusion injury.Methods： Forty SD rats were divided into four sets： sham operation group（sham group）; intestinal ischemia/reperfusion group（I/R group）; EA preconditioning at ST 36 followed by intestinal ischemia/reperfusion injury（ST 36 ＋ I/R group）; EA preconditioning at the lateral site away from ST360.5 cm followed by intestinal ischemia/reperfusion injury（N＋I/R group）. For the sham group, the rats were opened abdominal cavity for 3 h and 20 min and their abdominal cavities were covered with wet gauze avoiding drying and kept on the thermostat at 37 0 C. For the ischemia/reperfusion（I/R） group,rats were anaesthetised and their abdominal cavities were opened to expose jejunum segments. The segment＇s collateral blood supply was restricted by bilateral ligation of the intestine. Next, one of the branches of a mesenteric artery was occluded with a thread for 20 min and then the thread was released after such ischemia conditions, keeping reperfusion for 3 h. For the ST36 ＋ I/R group, the electroacupuncture at ST36 was first performed, then the intestinal ischemia/reperfusion model was constructed. For the N ＋ I/R group, electroacupuncture at non ST36 acupoint, which is away from ST36 about 0.5 cm, and then the intestinal ischemia/reperfusion model was performed. Measurements of the levels of inflammatory markers tumour necrosis factor a（TNFa） and interleukin-1 beta（IL-1β）, cytochrome c（CYCS）, and the mitochondrial membrane pro-apoptotic protein（BAX）, anti-apoptotic protein Bcl-2 were performed.Results： Compared to I/R group, the intensity of cytoplasmic CYCS in intestinal tissues was significantly decreased in the ST 36 ＋ I/R group（1.65 vs. 0.18, p〈0.05）. Compared to N ＋ I/R group, the intensity of cytoplasmic CYCS in intestinal tissues was also dramatically declined in the ST 36 ＋ I/R group（1.37 vs. 0.18, p〈0.05）. The level of CYCS in mitochondria in rats in the ST 36 ＋ I/R group were appreciably increased than those of rats in the I/Rgroup（1.42 vs. 0.06, p〈0.05）, and CYCS in mitochondria was also largely expressed in ST36 ＋ I/R group than N ＋ I/R group（1.42 vs. 0.08, p〈0.05）. Bcl-2 was shown to be elevated in the ST 36 ＋ I/R group than I/R group（1.01 vs. 0.10） and N ＋ I/R group（1.01 vs. 0.09, all p〈0.05）, whereas BAX expression was greatly decreased in the ST36 ＋ I/R group than I/R group（0.11 vs.0.78） and N ＋ I/R group（0.11 vs. 0.87, all p〈0.05）.Conclusion： The results suggest the EA intervention has a protective effect upon mitochondria, preventing CYCS release and the subsequent activation of downstream apoptosis pathway. It is proposed that patients due to undergo gastrointestinal surgery get benefit from EA preconditioning at ST 36.

文摘OBJECTIVE:To evaluate the effect of electroacupuncture on rapid gastric emptying by comparing the effectiveness of electroacupuncture at both Zusanli(ST36)and Zhongwan(CV12)(He-Mu acupoints)versus electroacupuncture at Zhongwan(CV12)alone.METHODS:Sixty-five patients were randomly divided into two groups;33 patients in the He-Mu acupoints group received electroacupuncture at both Zusanli(ST36)and Zhongwan(CV12),while 32 patients in the single acupoint group received electroacupuncture only at Zhongwan(CV12).Both groups were treated once daily for 30 min,five times per week for 3 weeks.Before and after the 3-week treatment course,patients underwent gastric emptying scintigraphy and were assessed using the Traditional Chinese Medicine(TCM)symptom scale of gastrointestinal diseases.The two groups were compared regarding the percentages of gastric retention at 30 and 60 min and the TCM symptom scores.RESULTS:After the treatment course,the percentages of gastric retention at 30 and 60 min were significantly improved in both groups compared with the pre-treatment values(P<0.01).The improvement in the gastric retention was significantly better in the He-Mu acupoints group than the single acupoint group at 30 min(P<0.01)and 60 min(P<0.05).The TCM symptom score was significantly decreased after the treatment course in both groups(P<0.01).The improvement in the TCM symptom score was significantly better in the He-Mu acupoints group than the single acupoint group(P<0.01).The total effective rate was 93.55%(29/31)in the He-Mu acupoints group and 77.42%(24/31)in the single acupoint group.The treatment effect was better in the He-Mu acupoints group than the single acupoint group(P<0.05).CONCLUSIONS:Electroacupuncture at both Zusanli(ST36)and Zhongwan(CV12)or at Zhongwan(CV12)alone is effective in treating rapid gastric emptying.Furthermore,electroacupuncture at both Zusanli(ST36)and Zhongwan(CV12)is more effective than electroacupuncture at Zhongwan(CV12)alone.
文摘Objective:To observe the effect of point injection at Zusanli(ST36)plus abdominal point application on gastrointestinal dysfunction after laparoscopic surgery.Methods:A total of 204 patients with gastrointestinal dysfunction after laparoscopic surgery were recruited and divided into four groups using the random number table method,with 51 cases in each group.The control group received conventional postoperative intervention.In addition to the treatment in the control group,the point injection group was given point injection at Zusanli(ST36),the application group was offered abdominal point application,and the integrated group received point injection at Zusanli(ST36)and abdominal point application.The treatment lasted 3 consecutive days in all four groups.The recovery time of gastrointestinal function indicators and the incidence rate of postoperative nausea and vomiting(PONV)were observed and recorded.Before and after treatment,the visual analog scale(VAS)was used to assess abdominal pain intensity,the venous blood type 1 helper T cells/type 2 helper T cells(Th1/Th2)was determined,the serum levels of interleukin(IL)-6 and interferon(IFN)-γwere detected using the enzyme-linked immunosorbent assay,and the plasma levels of motilin and gastrin were measured using radioimmunoassay.Results:Compared to the control group,the first exhaust time,the first defecation time,and the time of restoring fluid diet came earlier in the other three groups(P<0.05)and were earlier in the integrated group than in the point injection and application groups(P<0.05).The point injection,application,and integrated groups had a lower PONV incidence rate than the control group,and the integrated group was lower than the point injection and application groups(P<0.05).The intra-group comparisons showed that the VAS score and the levels of IL-6 and INF-γdecreased after treatment in all four groups(P<0.05);the point injection,application,and integrated groups were lower than the control group(P<0.05),and the integrated group was lower than the point injection and application groups(P<0.05).The intra-group comparisons also demonstrated that the levels of Th1/Th2,motilin,and gastrin increased after the intervention in the four groups(P<0.05);the point injection,application,and integrated groups were higher than the control group(P<0.05),and the integrated group was higher than the point injection and application groups(P<0.05).Conclusion:Point injection at Zusanli(ST36)plus abdominal point application can encourage postoperative exhaust,defecation,and the recovery of diet fluid,alleviate postoperative abdominal pain,reduce PONV,balance Th1/Th2,and regulate the secretion of motilin and gastrin in patients with gastrointestinal dysfunction after laparoscopic surgery.

文摘Zusanli (ST36), one of the most essential acupoints in clinical acupuncture practice, is considered as anintervention strategy for disease prevention and longevity promotion in traditional Chinese medicine (TCM).However, the prophylactic effects of ST36 have yet to be investigated in clinical studies. In the present study, weconducted a single-arm, open-label, pilot clinical trial to evaluate the prophylactic effects of stimulating the ST36acupoint through acupuncture and moxibustion in middle-aged and elderly participants. Of the 85 participantswho completed the first 2 months of acupuncture and moxibustion, 48 continued through the remaining 4 monthsto complete the full 6-month intervention. For 6 months acupuncture and moxibustion at ST36 significantlyreduced levels of low-density lipoprotein (LDL) and uric acid (UA) in individuals with initially abnormal LDLand UA values. The median LDL levels decreased from 4.46 mmol/L (IQR 4.32–4.71) to 3.97 mmol/L (IQR3.32–4.47) (P = 0.004) and the median UA levels decreased from 399.00 μmol/L (IQR 356.00–483.00) to 361.00μmol/L (IQR 323.00–421.00) (P = 0.003). Additionally, ST36 intervention led to marked reductions in the levels oflactic dehydrogenase (LDH) (266.50 U/L (IQR 257.50–282.25) to 235.50 U/L (IQR 215.50–244.75), P < 0.001) at 6months, and α-hydroxybutyrate dehydrogenase (α-HBDH) (195.50 U/L (IQR 190.25–212.00) to 181.00 U/L (IQR165.75–187.25), P = 0.017) at 2 months. Notably, ST36 acupuncture and moxibustion also showed positive effectson sleep quality, knee joint function, and bowel movement patterns, and there were no syncope, severe pain orother adverse reactions. These findings provide clinical evidence that ST36 acupoint stimulation confers holistichealth benefits for middle-aged and elderly populations, while maintaining an excellent safety profile.

文摘Objective To explore the experimental method of obtaining position emission tonogiaphy (PET) imaging evidence of changes in cerebral function by puncturing the Stomach 36 (ST36, Zusanli) acupoint.Methods Data on changes of cerebral glycometabolism were obtained from six healthy male volunteers with positron emission tomography. Visual experimental evidence, as well as statistical parametric mapping (SPM), was gathered while puncturing the ST36 (Zusanli, right leg) acupoint.Results There was increased glycometabolism in the hypothalamus, head of the caudate nucleus, temporal lobe, the sinistral cerebellum, postcentral gyrus, and brain stem while the acupoint ST36 was being punctured. Conclusions Acupuncture on ST36 can lead to increase in glycometabolism in the vegetative nerve centers, which is correlated with gastric function. Visual experimental evidence of ST36 acupuncturing on functional gastrointestinal disorder was obtained in our study.

文摘Objective: To investigate the effects of paired ST36 and RN12 acupuncture stimulation on gastric motility and the firing rate of responsible neurons in anesthetized rats.Methods: Using electrophysiological methods, we measured the effects of acupuncture at RN12, ST36, or RN12+ST36 on gastric motility as well as nerve discharges from the gastric sympathetic, vagal nerve, and wide dynamic range(WDR) neurons in the spinal dorsal horn T7-9 in anesthetized rats.Results: 1) Acupuncture at RN12 inhibited gastric motility(83.84±4.49)% and vagal nerve discharge(65.64±5.67)%, but promoted sympathetic nerve activity(243.70±40.67)%; acupuncture at ST36 induced opposing effects on gastric motility(111.31±2.01)% and vagal nerve discharge(166.98±15.92)%. Interestingly, acupuncture at RN12+ST36 together yielded effects similar to that of acupuncture at RN12 alone(93.59±2.05)%,(54.52±7.12)%. 2) WDR neuron discharges induced by gastric distension were inhibited by acupuncture at RN12(194.56 ±18.79)%. However, acupuncture at ST36 induced a more significant inhibitory effect.Conclusion: Acupuncture at RN12 inhibits gastric motility by activation of the sympathetic reflex at the spinal level; acupuncture at ST36 promotes gastric motility by activation of the parasympathetic reflex at the supraspinal level, and acupuncture at RN12+ST36 produces a similar decrease in gastric motility as RN12 stimulation alone. Both acupoints decrease the effect of noxious gastric distention on WDR neuron activity, but paired RN12+ST36 stimulation does not significantly affect WDR neuron discharge.
