E®ect of laser acupuncture combined with electrical stimulation on recovery from exercise fatigue in mice

In sports events,the rapid recovery after high-intensity training or sport competition performance is very important for athletes'performance and health.The aim of this study is to evaluate the effect of laser acupuncture and electrical stimulation on the recovery from exercise fatigue,using mice with swimming fatigue as experimental model and the electromyography(EMG)and the Raman spectroscopy of blood as evaluation indicators.Root mean square(RMS)and mean power frequency(MPF)of EMG were analyzed after laser acupuncture and electrical stimulation.The amplitude frequency combined analysis(JASA)showed that the proportion of muscles in the fatigue recovery area of the control group,the laser acupuncture group,the multi-channel laser acupuncture group and the laser combined with electrical stimulation group were 34.78%,39.13%,39.13%and 43.48%,respectively.Raman spectroscopy of the mice blood during fatigue recovery showed there is a significant difference between the multi-channel laser acupuncture group and the laser combined with electric stimulation group compared with the recovery period and fatigue period(P<0:05)at the peak of 997 cm^(-1) and the laser combined electrical stimulation group had a statistical difference in the recovery period compared with the fatigue period(P<0.05)at the peak of 1561 cm^(-1).The results showed that laser acupuncture combined with electrical stimulation was beneficial to fatigue recovery in mice,and had the potential value in sports fatigue recovery.

Effect and mechanism of electroacupuncture at"Baihui"and"Shenshu"on improving cognitive impairment in APP/PS1 mice

Objective:To observe the effect of electroacupuncture(EA)at"Baihui"(GV20)and"Shenshu"(BL23)on cognitive impairment in AD model mice,and to explore its mechanism.Methods:A total of 24 model mice were randomly divided into EA,medication and model groups,8 mice in each group.Another 8 C57BL/6J mice were used as the normal control.The rats in the EA group were treated with electrical stimulation at Baihui(GV20)and Shenshu(BL23),and those in the medication group were treated with donepezil hydrochloride,once a day for 21 days.Adopting the Maorris water maze method to detect the behavior of mice and using HE staining to observe the morphological structure of neurons in the hippocampal region of mice.Finally the expression of GSK-3βandβ-catenin protein contents in the hippocampus of mice in each group was detected by Western blot.Results:Compared to the model group,the evasion latency of the electroacupuncture group and the western medicine group were significantly shorter,and the dwell time in the target quadrant and the number of crossing the plateau were increased(P<0.05),and the hippocampal neurons in each treatment group were closely arranged and complete,with a clearer hierarchy.Western blot assay results showed that the expression ofβ-catenin protein was significantly increased and GSK-3βprotein expression was decreased in the hippocampal region of mice in the electroacupuncture and western medicine groups compared with the model group(P<0.05).Conclusion:Ea at"Baihui"(GV20)and"Shenshu"(BL23)can significantly improve the cognitive function of APP/PS1 mice,which may be connected with the activation of Wnt/β-catenin signaling pathway.

A randomized trial comparing the Tennant Biomodulator to transcutaneous electrical nerve stimulation and traditional Chinese acupuncture for the treatment of chronic pain in military service members

Background:The present investigation tested the efficacy of the Tennant Biomodulator,a novel pain management intervention that uses biofeedback-modulated electrical stimulation,to reduce chronic pain and its psychosocial sequelae in a sample of current and former military service members.The Tennant Biomodulator used on its most basic setting was compared to two commonly used,non-pharmacological pain treatments—traditional Chinese acupuncture and transcutaneous electrical nerve stimulation(TENS)—in a comparative efficacy,randomized,open-label trial.Methods:Participants included 100 active duty and retired service men and women with chronic pain undergoing treatment at the Brooke Army Medical Center in Texas,USA,randomly assigned to receive six,weekly sessions of either Tennant Biomodulator treatment,traditional Chinese acupuncture,or TENS,in addition to usual care.Recruitment was conducted between May 2010 to September 2013.Outcome measures were collected at intake,before and after each treatment session,and at a 1-month follow-up.Intent-to-treat analyses were used throughout,with mixed models used to investigate main effects of group,time,and group×time interactions with consideration given to quadratic effects.Outcomes measured included ratings of chronic pain,pain-related functional disability,and symptoms of post-traumatic stress disorder(PTSD)and depression.Results:On average,regardless of their treatment group,participants exhibited a 16%reduction in pain measured by the Brooke Army Medical Center’s Clinic Pain Log[F(1,335)=55.7,P<0.0001]and an 11%reduction in pain-related disability measured by the Million Visual Analog Scale[MVAS:F(1,84)=28.3,P<0.0001]from baseline to the end of treatment,but no one treatment performed better than the other,and the reductions in pain and pain-related disability were largely lost by 1-month follow-up.Symptoms of PTSD and depression did not change significantly as a function of time or group.Conclusions:Findings build on previous work suggesting that traditional Chinese acupuncture and TENS can reduce pain and its functional sequelae without risks associated with pharmacological pain management.The Tennant Biomodulator used on its most basic setting performs as well as these other interventions.Based on the present findings,large,randomized controlled trials on the Tennant Biomodulator are indicated.Future work should test this device using its full range of settings for pain-related psychological health.Trial registration:Clincialtrials.gov(NCT01752010);registered December 14,2012.

A CONTROLLED STUDY OF THERAPEUTIC EFFECTS OF COMPUTER-CONTROLLED ELECTRIC ACUPUNCTURE TREATMENT ON REFRACTORY SCHIZOPHRENIA

Out of 100 cases of intractable schizophrenia,57 cases were in the group ofComputer-Controlled Electric Acupuncture (CCEA) and 43 in the control group.The therapeutic re-sults showed that clinically CCEA had a remarkably effective rate of 40. 35% on refractoryschizophrenia,which had much better curative effects than those in the control group.Through dy-namic evaluation of brief psychiatric rating scale (BPRS),negative symptom scale (SANS) and posi-tive symptom scale (SAPS) for both groups before,during and after treatment,the results indicatedthat in CCEA group the scores of BPRS,SANS and SAPS after treatment were much less than thosebefore treatment,which were remarkably different from those in the control group (P【0.01).Lab-oratory examination of thyroxin and androgen of patients in both groups before and after treatmentfound a significant result.

Acupuncture transcutaneous electrical nerve stimulation reduces discomfort associated with barostat-induced rectal distension:A randomized-controlled study

AIM:To explore the effectiveness of acupuncture transcutaneous electrical nerve stimulation(Acu-TENS), a non-invasive modality in reduction of rectal discomfort during barostat-induced rectal distension. METHODS:Forty healthy subjects were randomized to receive 45 min of either Acu-TENS or placebo-TENS(no electrical output)over acupuncture points Hegu(largeintestine 4),Neiguan(pericardium 6)and Zusanli(stomach 36).A balloon catheter attached to a dual-drive barostat machine was then inserted into the subjects'rectum.A step-wise(4 mmHg)increase in balloon pressure was induced until maximal tolerable or 48 mmHg.Visual analogue scale and a 5-point subjective discomfort scale(no perception,first per-ception of distension,urge to defecate,discomfort/ pain and extreme pain)were used to assess rectal discomfort at each distension pressure.Blood beta-endorphin levels were measured before,immediately after intervention,at 24 mmHg and at maximal toler- able distension pressure. RESULTS:There was no difference in the demographic data and baseline plasma beta-endorphin levels between the two groups.Perception threshold levels were higher in the Acu-TENS group when compared to the placebo group,but the difference reached statistical significance only at the sensations"urge to defecate"and"pain".The distension pressures recorded at the"urge to defecate"sensation for the Acu-TENS and placebo-TENS groups were 28.0±4.5 mmHg and 24.6±5.7 mmHg,respectively(P=0.043);and the pressures recorded for the"pain"sensation for these two groups were 36.0±4.2 mmHg and 30.5± 4.3 mmHg respectively(P=0.002).Compared to the placebo group,a higher number of participants in the Acu-TENS group tolerated higher distension pressures (>40 mmHg)(65%in Acu-TENS vs 25%in placebo, P=0.02).The plasma beta-endorphin levels of the Acu-TENS group were significantly higher than that of the placebo group at barostat inflation pressure of 24 mmHg(1.31±0.40 ng/mL vs 1.04±0.43 ng/mL,P= 0.044)and at maximal inflation pressure(1.46±0.53 ng/mL vs 0.95±0.38 ng/mL,P=0.003). CONCLUSION:Acu-TENS reduced rectal discomfort during barostat-induced rectal distension and concur-rently associated with a rise in beta-endorphin level.

Objective: To compare the clinical therapeutic effects on the syndrome of L3 transverse process between thick silver warming needling and electric acupuncture. Methods: One hundred and twenty cases of the syndrome of L3 transverse process were randomized into observation group and the control, 60 cases for each one. Thick silver warming needling was applied in observation group and electric acupuncture in the control. Results: The curative rate was 81.7% in observation group and 58.3% in the control, indicating significant difference （P<0.01）. The significant difference in the therapeutic effects between two groups had not been discovered yet for the cases within 3 months of sickness （P>0.05）, but, the therapeutic effect in observation group was superior to that in the control for the cases over 3 months of sickness （P<0.01）. Conclusion: The therapeutic effects of thick silver warming needling and electric acupuncture were quite advantageous on the syndrome of L3 transverse process, but that of thick silver warming needling was superior to electric acupuncture.

Facial nucleus up-regulation of brain-derived neurotrophic factor mRNA following electroacupuncture treatment in a rabbit model of facial nerve injury

BACKGROUND： The effect of acupuncture treatment on peripheral facial nerve injury is generally accepted. However, the mechanisms of action remain poorly understood. OBJECTIVE： To validate the effect of acupoint electro-stimulation on brain-derived neurotrophic factor （BDNF） mRNA expression in the facial nucleus of rabbits with facial nerve injury, with the hypothesis that acupuncture treatment efficacy is related to BDNE DESIGN, TIME AND SETTING： Peripheral facial nerve injury, in situ hybridization, and randomized, controlled, animal trial. The experiment was performed at the Laboratory of Anatomy, Heilongjiang University of Chinese Medicine from March to September 2005. MATERIALS： A total of 120 healthy, adult, Japanese rabbits, with an equal number of males and females were selected. Models of peripheral facial nerve injury were established using the facial nerve pressing method. METHODS： The rabbits were randomly divided into five groups （n = 24）： sham operation, an incision to the left facial skin, followed by suture; model, no treatment following facial nerve model establishment; western medicine, 10 mg vitamin B1, 50 ug vitamin B12, and dexamethasone （2 mg/d, reduced to half every 7 days） intramuscular injection starting with the first day following lesion, once per day; traditional acupuncture, acupuncture at Ytfeng, Quanliao, Dicang, Jiache, Sibai, and Yangbai acupoints using a acupuncture needle with needle twirling every 10 minutes, followed by needle retention for 30 minutes, for successive 5 days; electroacupuncture, similar to the traditional acupuncture group, the Yifeng （negative electrode）, Jiache （positive electrode）, Dicang （negative electrode）, and Sibai （positive electrode） points were connected to an universal pulse electro-therapeutic apparatus for 30 minutes per day, with disperse-dense waves for successive 5 days, and resting for 2 days. MAIN OUTCOME MEASURES： Left hemisphere brain stem tissues were harvested on post-operative days 7, 14, 21, and 28 under a dissecting microscope. Neuronal appearance in the facial nucleus was observed following Nissl staining. BDNF mRNA expression in the facial nucleus was determined using in situ hybridization. RESULTS： A total of 120 rabbits were included in the final analysis. In the model group, the nucleolus was asymmetric with cell body swelling, and the number of Nissl bodies decreased. With increasing time, there were more Nissl bodies in the western medicine, traditional acupuncture, and electroacupuncture groups, in particular the electroacupuncture group. However, the number of Nissl bodies remained less than in the sham operation group. The number of BDNF-positive neurons in the facial nucleus was significantly greater in the western medicine, traditional acupuncture, and electroacupuncture groups, compared with the model group （P 〈 0.01）. The number of BDNF-positive neurons in the facial nucleus of reached a minimum in the electroacupuncture group on post-surgery day 21, and increased by day 28, but remained less than control levels. CONCLUSION： Electroacupuncture at acupoints increased BDNF expression in the facial nucleus, alleviated neuronal injury in the facial nucleus, and promoted facial nerve regeneration. The effect was superior over traditional acupuncture and western medicine.

ELECTRO-ACUPUNCTURE TREATMENT OF ACUTE STAGE PERIPHERAL FACIAL PARALYSIS

The use of electro-acupuncture in treatingperipheral facial paralysis during the acute stagehas been a controversial issue among acupunc-turists.Since 1970,100 cases of acute stage peri-pheral facial paralysis(1-10 days after onset)have been treated with electro-acupuncture witha curs rate of 84% and an effective rate of 100%,no cases showing aggravation of symptoms aftertreatment.Electro-acupuncture is therefore usefulin the treatment for acute stage peripheral facialparalysis.

Evaluating Training Programs for Electroacupuncture Techniques with Skin Temperature as a New Index

Training in acupuncture techniques has a long history of thousands of years. It has been individually handed down from person (teacher) to person (student). However, techniques and training have not been scientifically evaluated because individual differences may exist among evaluators. In animal studies, some researchers have reported that acupuncture stimulation dilates blood vessels of the skin and skeletal muscles. These studies also reveal an association between skin temperature (ST) and blood circulation volume on the skin. Our previous studies have reported that acupuncture stimulation, especially that of electroacupuncture (EA), can elevate ST. Therefore, we monitored the instructive effects and level of EA techniques with ST and propose that we can bring monitoring ST into training/education of EA as a new index of technical assessment. Moreover, ratio of changes might be used as new criteria for retraining. Healthy students (n = 14) were given with 10 minutes of EA stimulation on the tibialis anterior: Zusanli (ST36) and Tiaokou (ST38). Their ST was monitored before and during stimulation as well as for 30 minutes after stimulation. All subjects showed a nominal increase in ST. At the time, ratios of changes were also calculated. Two subjects did not reach the average of 1.3%. This suggests that the technical level of the therapist was inadequate. Thus, observation of ST elevation and calculation of the average ratio of ST change (elevation) could be applied to a new scientific index of technical assessment in acupuncture treatment training. However, further research (e.g., larger-scale studies, adjustment for gender differences, or other age subjects) is required to support these findings.

Effect of transcutaneous electrical acupoint stimulation combined with palonosetron on chemotherapy-induced nausea and vomiting: a single.blind,randomized, controlled trial

Background: Chemotherapy?induced nausea and vomiting adversely affects the quality of life of patients who receive chemotherapy via intravenous infusion or transcatheter arterial chemoembolization(TACE). This study aimed to investigate the clinical effects of transcutaneous electrical acupoint stimulation(TEAS) on nausea and vomiting after TACE.Methods: A total of 142 patients who received TACE with cisplatin for primary or metastatic liver cancer were assigned to the active?acupuncture(n = 72) or placebo?acupuncture(n Hegu(LI4), Neiguan(P6), an= 70) groups using a covariate?adaptive randomization at a ratio of 1:1. The acupointsd Zusanli(ST36) were stimulated twice daily for 6 days. The effects of TEAS on nausea and vomiting were assessed by using occurrence rate and severity of these symptoms. Anorexia scale and M. D. Anderson Symptom Inventory(MDASI) scores were secondary endpoints and were used to assess the effect of TEAS on patient appetite and quality of life. The safety of the treatments was also monitored.Results: Between the two groups, the differences in occurrence rates and severities of nausea and vomiting after TACE were not significant(all P > 0.05). From the second day after TACE, anorexia scores were significantly lower in the active?acupuncture group than in the placebo?acupuncture group and continued to decrease over time with treat?ment(all P values less than 0.01). On days 0, 1, and 2, the mean MDASI scores for the active?acupuncture group were slightly lower than those for the placebo?acupuncture group, but the differences were not statistically significant(all P > 0.05). No significant differences were found between the two groups in the occurrence rate of any adverse event(P > 0.05).Conclusion: TEAS appears to be a safe and effective therapy to relieve patients' gastrointestinal discomfort after chemotherapy.

Acupuncture in preventing postoperative nausea and vomiting:a systematic review and Bayesian network meta-analysis

However,the best choice of acupuncture therapy for postoperative nausea and vomiting remains controversy.Methods:Several databases were searched from inception to April 2020.Randomized controlled trials met the criterion were included.Risk of bias was implemented with Cochrane risk-of-bias tool.Addis,R,OpenBUGS and STATA were used to conduct meta-analysis.The evidence was assessed by GRADE profiler 3.6.Results:Fifty studies involving 5980 patients were included.The risk of bias of most included studies were acceptable.The results of network meta-analyses indicated,compared with placebo,electroacupuncture was the best choice for postoperative nausea(odds ratio=0.09,95%confidence interval:0.02-0.51)and acupoint plaster for postoperative vomiting(odds ratio=0.07,95%confidence interval:0.01-0.42),acupoint catgut embedding+5HTRA for postoperative nausea and vomiting(odds ratio=0.05,95%confidence interval:0.01-0.15),and transcutaneous electrical nerve stimulation+5-hydroxytryptamine receptor antagonists for postoperative rescue antiemetics(odds ratio=0.14,95%confidence interval:0.08-0.46).Conclusion:It was suggested transcutaneous electrical nerve stimulation+5-hydroxytryptamine receptor antagonists was the best choice.The results provided guidance for the prevention of postoperative nausea and vomiting.

Objective:To explore the rules of acupuncture point selection in thetreatment of rheumatoid arthritis by applying data mining and modern Statistical software.Methods:We retrieved literature from China hownet(CNKI),VIP database(VIP),Wanfang,PubMed,MEDLINE,Embase database from the founding of the database to February 1,2020.The main information of meridians and acupoints were entered into Excel,SPSS22.0 was used to extract data and do clustering analysis.Results:Quchi,Zusanli,Hegu,Yanglingquan,Xiyan were often chosen for electropuncture treatment of rheumatoid arthritis.Most of the acupoints are located in the large intestine channel of hand yangming bladder meridian or bladder channel of foot Taiyang,Shaoyang gallbladder channel of foot,stomachmeridian of foot Yangming,the energizer meridian and concentrated in the upper and lower extremities.The frequency of use of five Shu points,crossing point,source point,lowerconfluent and eight meeting points acupoints is higher.Cluster analysis can divide the included acupoints into 5 clusters.Conclusion:Quchi,Zusanli,Hegu,Yanglingquan,Xiyan are often chosen for electropuncture treatment of rheumatoid arthritis.Most of the selected acupoints aremostly distributed in the acupoints which are located in the large intestine channel of hand yangming bladder meridian or bladder channel of foot Taiyang,Shaoyang gallbladder channel of foot,Stomach meridian of foot Yangming,and the energizer meridian.

EFFECT OF ACUPUNCTURE COMBINED WITH EPIDURAL ANESTHESIA ON PLASMA CATECHOLAMINE CONTENT IN CHOLECYSTECTOMY PATIENTS

Objective: To observe changes of plasma catecholamine (CA) level in patients experiencing cholecystectomy under acupuncture anesthesia combined with epidural administration of small dose of anesthetics. Methods: 33 cholecystectomy patients were randomly divided into acupuncture combined with epidural anesthesia (A) group (n=11), acupoint skin electrical stimulation combined with epidural anesthesia (B) group (n=11) and simple epidural anesthesia (C) group (n=11). Acupoints used were bilateral Zusanli (ST 36) and Neiguan (PC 6) and stimulated with parameters of frequency 2/15 Hz, intermittent waves, electric current 2～3 mA for group A and 13mA for group B. Extradural anesthetic administered was 1.5% Lidocaine 5 mL. Venous blood samples were collected one day before, during and 3 days after operation for detecting plasma NE, E and DA contents. Results: ① During operation, plasma NE of group A and B lowered in comparison with pre operation, particularly group A (P<0.01), while in group C, plasma NE level increased slightly; plasma E of group A and B increased significantly compared with pre operation (P< 0.01). Plasma DA in the 3 groups all raised during operation. ② Three days after operation, plasma NE, E and DA levels recovered basically in comparison with those of one day before operation. It indicates that acupuncture or acupoint skin electrical stimulation is capable of regulating sympathetic activity during epidural anesthesia. The anesthetic effect has a closer relation with changes of plasma NE level rather than changes of plasma E or DA levels. Conclusion: Acupuncture or acupoint surface electrical stimulation combined with epidural anesthesia may be of reducing or releasing surgical operation generated stress response during cholecystectomy.
