Effect of electroacupuncture at different acupoints in treating rapid gastric emptying:Zusanli(ST36)plus Zhongwan(CV12)versus Zhongwan(CV12)alone

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.

Moxibustion at ST36 activates peritoneal macrophages in CTX-induced immunosuppression in mouse model via IFN-γ

Background:To explored whether moxa cone moxibustion can reduce peritoneal inflammation by increasing the content of peritoneal macrophages and B cells via interferon-gamma.Methods:The mice were randomly divided into three groups with six mice in each group:the control group,model group,and moxibustion group,and the model was established in mice using cyclophosphamide.In the moxibustion group,the mice received moxa cone moxibustion at Zusanli(ST36)for 7 days.Analysis of Peritoneal cell were detected by flow cytometry and immunofluorescence,the protein expression level in the peritoneal fluid were measured with mouse cytokine antibody arrays and verified by enzyme linked immuno sorbent assay test,and RNA-Sequencing was used for peritoneal cell RNA analysis.Results:Our results showed that moxa cone moxibustion could reduce the loss of large peritoneal macrophages and B1 cells(P<0.05).With the cytokine array analysis and enzyme linked immuno sorbent assay test of peritoneal fluid,we found that IFN‐γwas up-regulated in moxibustion group(P<0.05).There were 169 genes were down-regulated in the model group and up-regulated in the moxibustion group while 19 genes that were up-regulated in the model group and down-regulated in the moxibustion group via RNA-sequencing.Kyoto Encyclopedia of Genes and Genomes pathway analysis of 188 intersect differentially expressed genes were found that the top 3 pathways with the highest enrichment of up-regulated genes included Hematopoietic cell lineage,Inflammatory bowel disease and Malaria.The differentially expressed genes visualization protein-protein interaction network shows the top 10 genes including Ifng,Grb2,CCR7,CTLA4,CXCR5,Foxp3,kit,PRF1,CD5 and klrg1.Conclusion:These findings showed that moxa cone moxibustion can alleviate chemotherapy-induced diarrhea by reducing the loss of large peritoneal macrophages and B1 cells in the peritoneal cavity,possibly through up-regulating inflammatory bowel disease signaling pathway via interferon-gamma to regulate the survival and function of large peritoneal macrophages and B1 cells.

Effect of scar-producing moxibustion at the acupoints Zusanli(ST 36) and Feishu(BL 13) on neutrophil-to-lymphocyte ratio and quality of life in patients with non-small-cell lung cancer: A randomized,controlled trial

OBJECTIVE: To evaluate the effect of heat stimulation via scar-producing moxibustion at the acupoints Zusanli(ST 36) and Feishu(BL 13) on the neutrophil-to-lymphocyte ratio(NLR) and quality of life in patients with non-small-cell lung cancer(NSCLC).METHODS: Seventy patients with NSCLC were randomly assigned into two groups: group A received scar-producing moxibustion at the acupoints Zusanli(ST 36) and Feishu(BL 13) every day for 6 weeks, while group B received no intervention(control group). Outcome measures were the NLR and the scores from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30). The NLR and the EORTC QLQ-C30 were assessed at baseline and at the end of 6 weeks.RESULTS: Five participants dropped out, leaving afinal total of 65 participants who completed the trial. Groups A and B had a similar mean NLR at baseline. After the treatment course, the NLR in group A was significantly lower than that in group B(P <0.001). Compared with group B, the EORTC QLQ-C30 scores in group A were significantly greater in terms of global health status or quality of life(P < 0.001) and function(P < 0.05), and significantly lower in terms of symptoms(P < 0.05).CONCLUSION: The present study suggests that performing scar-producing moxibustion by heat-stimulating the acupoints Zusanli(ST 36) and Feishu(BL13) effectively decreases the NLR and improves the quality of life in patients with NSCLC.

Effect of dexamethasone injection into Zusanli(ST 36) acupoint on ovalbumin-induced allergic rhinitis

OBJECTIVE:To investigate the effects of acupunc ture with dexamethasone(A.Dex)on allergic rhini tis(AR)by injecting dexamethasone into the Zusan li(ST 36)acupoint.METHODS:Thirty 6-week-old female BALB/c mice were sensitized on days 1,5,and 14 by intraperitoneal injection of 100 pg of ovalbumin(OVA).The mice were then randomly divided into six groups(n =5 in each group).Five groups were sensitized intranasally with 2μL of 1.5 mg of OVA for 10 consecutive days,while one group was sensitized intranasally with PBS in a similar manner as a negative control group.One hour before each administration of intranasal OVA,two groups were orally administered either a control vehicle(distilled water;AR control group)or 200 pg/kg Dex(O.Dex group),while three groups received A.Dex at Zusanli(ST36)with Dex concentrations of 2,20,and 200μg/kg for each group,respectively.AR symptoms were evaluated by measuring the rubbing score,which comprised the number of nose,ear,and eye rubs that occurred in the initial 10 min after OVA intranasal provocation on the 10 th day.We isolated spleen,serum,and nasal mucosal tissue after measuring the rubbing score.Spleen weight was measured using an electronic microbalance.The levels of IgE,thymic stromal lymphopoietin,tumor necrosis factor-a,intercellular adhesion molecule-1,and macrophage-inflammatory protein-2 in serum or nasal mucosal tissue were measured using enzyme-linked immunosorbent assays.The serum histamine levels of OVA-sensitized AR mice were measured using O-phthaldialdehyde spectrofluorometry.Western blot analysis was performed on nasal mucosal tissue extracts.RESULTS:A.Dex significantly reduced the rubbing score,spleen weight,serum IgE,and serum histamine in OVA-sensitized mice.A.Dex significantly decreased the serum levels of inflammatory cytokines(thymic stromal lymphopoietin and tumor necrosis factor-a)in OVA-sensitized mice.A.Dex significantly reduced the nasal mucosal levels of inflammatory markers(intercellular adhesion molecule-land macrophage-inflammatory protein-2)in AR mice.A.Dex effectively attenuated the expression of caspase-1 and receptorinteractingprotein-2 in nasal mucosal tissue.CONCLUSION:A.Dex may be a new and useful therapy for AR.

Effects of electroacupuncture at Zusanli(ST36) on inflammatory cytokines in a rat model of smokeinduced chronic obstructive pulmonary disease

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.

Effects of pre-moxibustion at Zusanli (ST36) on heat shock protein 70 expression in rats with gastric mucosal lesions after neurotomy

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.

Comparison of protective effects of electroacupuncture and moxibustion at Zusanli(ST 36)on perinatal nicotine exposure-induced lung phenotype in rat offspring

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.

Electro-acupuncture at Zusanli(ST 36) to improve lower extremity motor function in sensory disturbance patients with cerebral stroke A randomized controlled study of 240 cases

BACKGROUND： Studies have shown that sensory transduction is a way to introduce needle sensation. OBJECTIVE： To observe the influence of electro-acupuncture at the ＂Zusanll＂ （ST 36） point on lower extremity motor function in various sensory disturbance patients with cerebral stroke. DESIGN, TIME AND SETTING： A randomized, controlled, clinical study was performed at the Department of Neurological Rehabilitation, China Rehabilitation Research Centre from September 2006 to June 2008. PARTICIPANTS： Patients with first-time cerebral infarction or hemorrhage, or with a stroke history, but no neurodysfunction （single damage）, were selected for this study. The subjects were right-handed and disease state was stable. A total of 240 inpatients were randomly assigned to the following groups： electro-acupuncture （n = 124） and control （n = 116）. The two groups were further assigned into sub-groups： no sensory disturbance, superficial sensory disturbance, deep sensory disturbance, and deep and superficial sensory disturbance. METHODS： On the basis of routine limb function training, the acupoint Zusanliwas utilized in all patients from the electro-acupuncture group. Perpendicular acupuncture was 3.0-4.0 cm deep. An electric acupuncture instrument was connected when patients developed the needle sensation, deqi. A stimulation pattern consisting of distant and dense waves of 50 Hz was used to elicit slight dorsal foot extension. Acupuncture was administered 5 times per week, 30 minutes per session, for 6 weeks in total. MAIN OUTCOME MEASURES： FugI-Meyer assessment （FMA） was used to evaluate lower extremity motor function; Ver.1.0 gait analysis to estimate gait （step frequency, step speed, and step scope）; lower extremity Composite Spasticity Scale （CSS） to estimate muscle spastic degree. RESULTS： Following treatment, motor function improved in both groups. Compared with the control group, FMA score, step speed, step frequency, and step scope were increased in the electro-acupuncture group, but there was no difference in lower extremity CSS scores between the electro-acupuncture and the control groups （P 〉 0.05）. Compared with the control group, Zusanli （ST 36） electro-acupuncture improved motor function indices as follows： FMA score, step frequency, step speed, and step scope of patients with no sensory disturbance （P 〈 0.05-0.01）, step frequency of patients with superficial sensory disturbance （P 〈 0.05）, and step frequency and step speed of patients with deep sensory disturbance （P 〈 0.05）. CONCLUSION： Zusanfi （ST 36） electro-acupuncture effects on lower extremity motor function in stroke patients were improved with no muscle tone rise. Therefore, this form of treatment can be used in convalescent treatment, Moreover, effects were different according to various sensory disturbance types, which suggested that sensory input influenced acupuncture effects.

目的观察电针足三里穴预处理对脂多糖(lipopolysaccharide,LPS)诱导的脓毒症小鼠肠黏膜功能损伤的保护作用及其机制研究。方法将40只美国癌症研究所(Institute of Cancer Research,ICR)小鼠随机分为正常组、模型组、电针组和非经非穴组,电针组小鼠选取足三里穴予以电针预处理,每日1次,每次30 min,持续5 d;第5天时采用腹腔注射LPS构建脓毒症肠黏膜损伤小鼠模型。通过苏木精-伊红(hematoxylin-eosin,HE)染色法观察小鼠回肠组织病理学改变并评分;采用酶联免疫吸附法(enzyme-linked immunosorbent assay,ELISA)检测小鼠血清中C-反应蛋白(C-reactive protein,CRP)、降钙素原(procalcitonin,PCT)和结肠组织中白细胞介素-1(interleukin-1,IL-1)、白细胞介素-6(interleukin-6,IL-6)、肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)表达水平;蛋白印迹(Western blot,WB)法测定结肠组织中IL-1、IL-6、TNF-α和闭合蛋白(occludin)表达的水平;免疫荧光法检测胞质紧密粘连蛋白-1(zonula occludens-1,ZO-1)和连接蛋白-5(claudin-5)在回肠组织的表达水平;逆转录聚合酶链式反应(reverse transcription polymerase chain reaction,RT-PCR)检测肌球蛋白轻链激酶(myosin light chain kinase,MLCK)、肌球蛋白轻链(myosin light chain,MLC)、ZO-1、claudin-5、occludin在结肠组织中的含量。结果电针组中因LPS引起细胞排列紊乱与缺失、结构破坏、腺体变形等病理损伤均有改善,电针组小鼠回肠组织病理评分明显低于模型组(P<0.05),电针组小鼠结肠组织中IL-1、IL-6和TNF-α的含量低于模型组(P<0.05)。与模型组比较,电针组小鼠血清中CRP和PCT含量较低(P<0.05),小鼠结肠组织中occludin蛋白、occludin mRNA、claudin-5 mRNA、ZO-1 mRNA的相对表达量较高(P<0.05),小鼠结肠组织中MLCK和MLC mRNA相对表达量较低(P<0.05)。结论电针足三里预处理可通过抑制炎症反应和MLCK/MLC信号通路上调紧密连接蛋白的表达,发挥对LPS诱导的脓毒症肠黏膜屏障功能损伤的保护作用。

电针对大鼠肝缺血再灌注损伤保护作用的研究

目的观察电针预刺激足三里和阳陵泉穴对大鼠肝脏缺血再灌注损伤的保护作用。方法将24只Sprague-Dawley(SD)雄性大鼠随机分为4组,模型组、非穴位组、穴位组和假手术组,每组6只。假手术组大鼠仅开腹腔暴露90 min后即关腹,模型组大鼠进行缺血90 min后再灌注处理,穴位组和非穴位组大鼠用电针预刺激30 min后再进行缺血90 min后再灌注处理。分别在再灌注4 h和24 h后,取大鼠肝脏组织进行苏木精-伊红(hematoxylin-eosin,HE)染色和组织髓过氧化物酶检测,比较血清丙氨酸转氨酶、天冬氨酸转氨酶、白介素-1β、白介素-6、白介素-10和肿瘤坏死因子-α的水平。结果再灌注4 h和24 h后,穴位组大鼠血清丙氨酸转氨酶、天冬氨酸转氨酶、白介素-1β、白介素-6和肿瘤坏死因子-α水平以及肝组织髓过氧化物酶表达均低于模型组(P<0.05),非穴位组上述指标与模型组比较差异无统计学意义(P>0.05)。结论电针预刺激足三里和阳陵泉穴对肝缺血再灌注损伤有一定的保护作用,可在提高肝功能、抑制炎症因子释放和减少中性粒细胞浸润方面发挥作用。
