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.

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.

Electroacupuncture at Feishu(BL13) and Zusanli(ST36) down-regulates the expression of orexins and their receptors in rats with chronic obstructive pulmonary disease

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.

Differences in thermal effects of moxibustion at Zusanli(ST 36) and Hegu(LI 4) on various facial areas in healthy people

OBJECTIVE:To study the effects of temperature on different facial areas by suspended moxibustion at two points,Zusanli(ST 36) and Hegu(LI 4),and probe the phenomena underlying self-regulation in the human body after thermal stimulation.METHODS:Thirty healthy volunteers accepted moxibustion over Zusanli(ST 36) and Hegu(LI 4),and the order of moxibustion points was randomly determined.Moxibustion method:suspension of moxibustion over Zusanli(ST 36) and Hegu(LI 4) on both sides was performed using an ignited moxa stick stuck in a support for 20 min.Observation method:An infrared thermal image of the face was taken before and after suspended moxibustion using a CK350 medical infrared thermal imaging instrument.Data analysis:A thermal microscopic section view system(TMTSys) was used to analyze the change in temperature in special facial areas.Statistical analysis was carried out using SPSS 14.0 software.RESULTS:Before moxibustion was suspended,the facial thermal image showed a T-shaped thermal area related to the vascular distribution with even temperature and good symmetry on both sides.Suspended moxibustion over Zusanli(ST 36) have a very significant increase in temperature at the forehead,around the nose,at the corners of the mouth,and at the cheeks and lips(P<0.01).Suspended moxibustion over Hegu(LI 4) also have a significant(P<0.05) increase in temperature around the nose,the corners of the mouth,the cheeks,and lips,where has a new high temperature area was formed(P<0.01).Suspended moxibustion over Hegu(LI 4) raised the temperature at the middle point of the lips more obviously than did Zusanli(ST 36) in the same person,(P<0.05).After 10 min of moxibustion over Zusanli(ST 36) and Hegu(LI 4),the change in temperature in the facial area reached its peak value.CONCLUSIONS:Facial infrared thermography of healthy people revealed a T-shaped thermal area reflecting a physiological thermal area.Moxibustion over Zusanli(ST 36) or Hegu(LI 4) raised the temperature in this facial T-shaped thermal area.Hegu(LI 4) led to the formation of a new thermal area in the lips.The time required for moxibustion to regulate human body temperature was 10 min.

Effect of moxa-burning heat stimulating Liangmen(ST 21) and Zusanli(ST 36) on proliferation and apoptosis signaling proteins in rats with stress-induced gastric ulcer

OBJECTIVE: To observe the effect of moxa-burning heat stimulating acupoints of Liangmen(ST 21)and Zusanli(ST 36) on the proliferation and apoptosis signaling proteins in rats with stress-induced gastric ulcer.METHODS: Forty rats were randomly divided into four groups: negative control(NC), ulcer control(UC), acupoints of stomach meridian(ASM), and acupoints control(AC). The acute gastric ulcer model was established by bound and water immersion.Rats in NC and UC groups didn't receive any moxa-burning heat stimulating treatment, while rats in ASM and AC groups were treated with buringmoxa heat stimulating the acupoints of Liangmen(ST 21) and Zusanli(ST 36) and their controlled points, respectively. Rats in all groups were sacrificed after 12 consecutive days treatment. The ulcer index was evaluated by using Guth's method.The expression of tumor necrosis factor-alpha(TNF-α), apoptotic protease activating facter-1(Apaf-1), Caspase-3, p21 activated kinase 1(PAK1),extracellular regulated protein kinases 2(ERK2),phosphorylated ERK2(p ERK2), phosphoinositide3-kinase(PI3K) and RAC-alpha serine/threonine-protein kinase(Akt) in gastric mucosa was detected by enzyme linked immunosorbent assay(ELISA).RESULTS: Compared with UC group, the ulcer index of ASM and AC groups decreased, and the injured gastric mucosa was improved, the expression of TNF-α, Apaf-1 and Caspase-3 in gastric mucosa was significantly reduced(P < 0.05), while the ex-pression of PAK1, ERK2, p ERK2, PI3 K and Akt in gastric mucosa was significantly increased(P < 0.05).And ASM showed better effect than AC group(P <0.05).CONCLUSION: Moxa-burning Heat stimulating of Liangmen(ST 21) and Zusanli(ST 36) could promote the recovery of gastric mucosal lesion probably by inhibiting cell apoptosis and promoting cell proliferation in stress-induced gastric ulcer.

Effect of electroacupuncture at Zusanli(ST 36) on dorsal root nerve signals in normal rats

OBJECTIVE: To investigate how electroacupuncture (EA) at Zusanli (ST 36) with varying intensities of stimulation affects dorsal root nerve signals in normal rats. METHODS: Adult female Wistar rats were examined after drug-induced anesthesia and isolation of the L4 dorsal root associated with the Zusanli (ST 36) acupoint, using bipolar platinum electrodes. We applied EA at Zusanli (ST 36) with a continuous wave waveform for 1 min, and recorded action potentials in the L4 spinal cord dorsal root nerve with a frequency of 5 Hz and various current intensity levels (approximately 1-4 mA). In addition, we tested EA with a frequency of 15 Hz and current intensity of 1-4 mA. The L4 spinal cord dorsal nerve bundle action potentials were measured for 1 min of EA. To analyze the discharge frequency, we used the maximum Lyapunov exponent and Lempel-Ziv (LZ) complexity. RESULTS: At a fixed frequency, with increasing intensity of EA, dorsal root nerve filament discharge frequency revealed an initial increase, followed by a decreasing trend. A stimulation intensity of 3 mA induced a significantly greater discharge frequency, compared with stimulation intensities of 2 and 4 mA. EA stimulation evoked neuroelectric signals with chaotic characteristics. Increased intensity led to an initial increase in LZ complexity which then decreased, with a stimulation strength of 3 mA inducing the highest level of LZ complexity. CONCLUSION: EA of different intensities can induce nerve action potential encoding with different features.
