摘要:Objective To explore the role of 26 Sproteasome and nuclear factor kappa B(NFκB)in substantia nigra in the management of Parkinson's disease(PD)by acupuncture.Methods Forty-eight male SD rats were randomly divided into normal,sham operation,model and electroacupuncture(EA)groups(12rats/group).The PD model was established by 40-day consecutive subcutaneous injection of rotenone(1mg/kg dissolved in dimethyl sulfoxide and normal saline)at the back shoulder.The rats in the sham operation group were treated by subcutaneous injection of dose of saline."Fengfu"(GV 16)and"Taichong"(LR 3)acupoints were stimulated with EA at 2Hz,1mA,20 min of duration in each treatment,and daily for 28 consecutive days.The behavioral changes of rats in each group were measured and scored at 40 th day and 68 th day,respectively.Immunohistochemistry was used to determine the expression of tyrosine hydroxylase(TH)used to detect the expression of 26 Sproteasome and NFκB and TH were measured by Western blot.Results In comparison with the normal and sham operation groups,the behavioral scores of rats in the model group were elevated,which were significantly decreased by EA intervention(P<0.05).The expression of TH and 26 Sproteasome decreased whereas the NFκB increased in the rats of model group(P<0.05),and EA intervention reversed these changes(all P<0.05).Conclusion EA intervention can improve PD rats' behavioral changes,which is pobably related to its effects in rcducing loss of TH-positive neurons,down-regulating NFκB protein expression,and upregulating 26 Sproteasome protein expression in the substantia nigra.
摘要:Objective To observe the effect of electroacupuncture(EA)intervention on the levels of CD 4+and CD 8+lymphocytes in the plasma and thymus in anxiety disorder rats,so as to explore its mechanism underlying favorable regulation of immune function.Methods Thirty-four SD rats were randomly divided into control(n=10),model(n=12)and EA(n=12)groups.The anxiety model was established by using chronic unpredictable emotional stress stimulation(fasting,water-deprivation,shaking,tail-clamping,forced warm-and cool-water swimming,electrical shock stimulation,etc.)for 15 days.EA(15Hz/25Hz)was applied to"Neiguan"(PC 6)and"Shenmen"(HT 7)for 15 min,once every other day for 15 days.The anxiety-like behavior was measured by elevated plus maze test.Anxiety reduction in the plus-maze is indicated by an increase in the proportion of time spent in the open arms(time in open arms/total time in open or closed arms),and an increase in the proportion of entries into the open arms(entries into open arms/total entries into open or closed arms).While the contents and expression of CD 4+and CD 8+in the plasma and thymus tissues were measured by ELISA and immunohistochemistry,respectively.Results The values of proportions of open-arm entries(OE%)and the content of plasma CD 4+lymphocytes were obviously lower in the model group than in the control group(P<0.05),and were significantly higher in the EA group than in the model group(P<0.05).Whereas,the content of plasma CD 8+lymphocytes was obviously higher in the model group than in the control group(P<0.05)and markedly down-regulated in the EA group after the treatment(P<0.05).The ratio of CD 4+/CD 8+was decreased in the model group in comparison with the control group(P=0.054),and was significantly up-regulated in the EA group after EA stimulation(P<0.01).Compared with the control group,the expression levels(optical density,OD values)of CD 4+and CD 8+lymphocytes in the thymus tissue were obviously decreased in the model group(P<0.01).After EA,the expression levels of thymus CD 4+and CD 8+were remarkably up-regulated in the EA group(P<0.05).No significant changes were found in proportion of open-arm time(OT%,P>0.05).Conclusion EA can effectively relieve anxiety disorder in anxiety rats,which may be related to its effects in up-regulating plasma CD 4+,thymus CD 4+and CD 8+levels as well as CD 4+/CD8+ratio,and down-regulating plasma CD 8+content.
摘要:Objective To observe the effect of acupuncture plus moxibustion on mitochondrial dynamics-related proteins(OPA 1,Fis 1)of hippocampal neurons in rat with Alzheimer's disease(AD),and to explore the potential mechanism underlying acupuncture for the protection of hippocampal neuronal mitochondria.Methods Eighty male Wistar rats were randomly divided into normal,sham-operation,model and acu-moxibustion groups.AD model was made by injecting Aβ1-42 into the hippocampus."Baihui"(GV 20)and"Shenshu"(BL 23)acupoints were stimulated by manual acupuncture(15min)in combination with moxibustion(15min)for two sessions of treatment,with seven consecutive treatments for one session and one day break between the two sessions.The expression of hippocampal OPA 1and Fis 1was assessed by means of Western blot and immunofluorescence technique.Results The expression level of OPA 1and Fis 1of rats in the model group was significantly lower and higher,respectively,than those of the normal and sham-operation groups(P<0.01).Acupuncture plus moxibustion intervention notably increased OPA 1and decreased Fis 1expression levels in the acu-moxibustion group compared to those of the model group(P<0.01).Conclusion Acupuncture combined with moxibustion produce benefit to hippocampal neurons in AD rats probably via the regulation of the mitochondrial dynamics(imbalance between fission and fusion proteins)and improvement of the mitochondrial damage of hippocampus.

摘要:Objective To observe the effect of electroacupuncture(EA)stimulation at Zhongwan(CV 12)on the skin microcirculatory blood flow along the Conception Vessel(CV)in yin-deficiency constitution volunteers.Methods A total of 16yin-deficiency constitution volunteers(9woman and 6men)from 200 students of Fujian University of Traditional Chinese Medicine finished a body constitution questionnaire and showed a yin-deficiency constitution.Skin microcirculatory blood perfusion units(MBPU)at Danzhong(CV 17),Xiawan(CV 10),and Qihai(CV 6)of the CV were measured by using a Laser Doppler Flowmetry(Peri Flux 5000)in normal constitution,before and after EA stimulation of Zhongwan(CV 12)for 20 min.Results Under normal condition,the cutaneous MBPU values were significantly lower in the Qihai(CV 6)than in both Danzhong(CV 17)and Xiawan(CV 10)(P<0.01).After EA stimulation of CV 12 for 20min,the MBPU values were significantly decreased in the CV 17 and CV 6acupoint regions compared with pre-stimulation(P<0.05).No significant changes of skin MBPU were found in Xiawan(CV 10)after EA stimulation of CV 12(P>0.05).Conclusion EA at Zhongwan(CV 12)can reduce the skin MBPU values of CV 6and CV 17 of the Conception Vessel in yin-deficiency constitution volunteers.
摘要:Proper combination of acupoints is one of the core issues of acupuncturology,and is also one of the factors affecting clinical outcomes.In the present paper,the authors make a review on the development of researches on the underlying mechanisms of acupoint combination for some clinical disorders from nerve system,humoral factors and immunological regulation.The neural mechanism involves both the peripheral nervous system(mainly the segmental innervation)and central nervous system(spinal cord,brainstem,hypothalamus,cerebral cortex and cerebellum),while the humoral factors chiefly contain neurotransmitters and hormones of the endocrine system.The immunological mechanisms involve immunocytes and cytokines.Generally speaking,following acupuncture stimulation of different combined-acupoints or acupoint groups,some synergistic effects may be produced.In fact,the relatively specific clinical effect may be easy to be obtained at the peripheral segmental innervations level.

摘要:Objective To assess the efficacy and safety of acupuncture in treating attention-deficit/hyperactivity disorder(ADHD)children.Methods A literature search was conducted to retrieve randomized cotrolled clinical trials of acupuncture in treating ADHD covering the period of the years of establishment of the databases to January 2014 from database of CBM,CNKI,PubMed,Cochrane Library by using key words"attention deficit hyperactivity disorder""hyperactivity""minimal brain dysfunction""acupuncture".Two independent researchers extracted data from located articles in a pre-defined structured way,and consulted the third researcher if necessary.Results Thirteen original trials including 1 304 cases of children with ADHD were obtained in this study according to our included criteria and excluded criteria.In these trials,acupuncture intervention alone,or acupuncture plus pharmacotherapy(methylphenidate,haloperidol)or acupuncture plus behavioral therapy were compared with simple pharmacotherapy or behavioral therapy alone.Results of Meta-analysis indicated that the total effective rate and Conners' index of hyperactivity(CIH)score-reduction rate in the acupuncture group were significantly superior to those of the other treatment groups[OR=2.22,95%CI(1.65,3.00),Z=5.22,P<0.00001][SMD=-0.94,95%CI(-1.41,-0.47),Z=3.89,P<0.0001].Acupuncture treatment is more effective than haloperidol in reducing the score of Conners' Rating Scale for ADHD [SMD=-7.28,95%CI(-8.32,-6.23),Z=13.62,P<0.00001].Acupuncture is similarly effective as Methylphenidate(Ritalin)in improving the Chinese medicine syndrome(liver-kidney yin hypoactivity)of children with ADHD [SMD=-1.14,95%CI(-2.53,0.25),Z=1.60,P=0.11].Less severe adverse effects were reported with acupuncture therapy than the pharmacotherapy(poor appetite,dry mouth,nausea and constipation).These effects were not likely due to publication bias(approximately symmetry funnel plot,Egger's test P>0.1).Conclusion Acupuncture is an effective and safe therapy in treating ADHD,combined administration of acupuncture and pharmacotherapy or behavioral therapy is more effective than the pharmacotherapy or behavioral therapy alone.However,more rigorously designed and high-quality RCTs are needed to confirm the above conclusion.
摘要:The national standard of"Regulations of Acupuncture-needle Manipulating Techniques"is one of the national Criteria of Acupuncturology for which a total of 22 items have been already established.In the process of formulation,a series of common and specific problems have been met.In the present paper,the authors expound these problems from 3aspects,namely principles for formulation,methods for formulating criteria,and considerations about some problems.The formulating principles include selection and regulations of principles for technique classification and technique-related key factors.The main methods for formulating criteria are 1)taking the literature as the theoretical foundation,2)taking the clinical practice as the supporting evidence,and 3)taking the expounded suggestions or conclusions through peer review.
摘要:"Feishu"(BL 13)is a commonly used acupoint in experimental study,but its definite position has not been described in current books about acupoints.In the present paper,the authors introduced three methods for determining the anatomical location of"Feishu"(BL 13)acupoint in rats.The Wistar rats(200±20)g were anesthetized with 10% chloral hydrate first,and then,fixed at the prone position.The highest point of the spinous process of the second thoracic vertebra was used as the marker for positioning the spinal vertebra.The point,7mm lateral to the site below the spinous process of the 3rd thoracic vertebra is just the"Feishu"(BL 13).In order to determine the 3rd thoracic vertebra,three methods are recommended to be adopted:1)finding the 5th thoracic vertebra process parallel to the inferior angle of the scapula first,then going upwards to find the 3rd thoracic vertebra,2)finding the 1st thoracic vertebra along the 1st rib,then going downward to find the 3rd thoracic vertebra,and 3)taking the 6th lumbar vertebra(parallel to the hip-joint)as the bone-marker and going upward to find the 3rd thoracic vertebra.When"Feishu"(BL 13)punctured,a filiform needle was straight inserted into the skin,then downward to the subcutaneous tissue,muscular layer(including the trunk cutaneous muscle,trapezius muscle,broadest muscle of back,serratus muscle of back,atalanto-longest muscle,longest muscle of neck,longest muscle of thorax,lumbar longest muscle,the medial part of the longest muscle,cervico-spinal muscle of back,semispinal muscle of neck,biventer cervicis,and multifidus muscles)about 6 mm in depth.
摘要:Long-lasting hypertension results in ventricular remodeling characteristic of myocardial hypertrophy including myocyte hypertrophy and myocardial fibrosis,apathological process failed to be blocked by the current biomedical means and could eventually lead to heart failure.It has been shown that acupuncture can excite the parasympathetic nerve to counter the overtonic activity of sympathetic nerve,elicit antihypertensive effect and produce cardioprotection via the regulation of calcium signaling-related proteins in myocytes,suggesting its potential role in the management of these disorders.In this paper,the authors review relevant studies and propose,with respect to the autonomic nerve,endocrine system,cytokines and intracellular calcium signaling pathways,several novel ideas concerning the treatment of hypertensive myocardial hypertrophy and cardiac malfunction by acupuncture.
摘要:In the initial stage(1950s)of the establishment of the People's Republic of China,the Pavlov's theory played an important influence on Chinese biology and medical science fields.At that time,many schools or colleges of traditional Chinese medicine were set up one after another,the first edition of teaching materials or textbook was complete,and a lot of advanced training courses and training classes were developed.In that specific period of"acupuncture scientification",Mr.MA Ji-xing,a professor from China Academy of Traditional Chinese Medicine,is a representative scholar who employed Pavlov's theory to make a scientific explanation about the underlying physiological mechanisms of acupuncture-moxibustion therapy.For example,he employed nerve network or nerve system to explain topical acupuncture stimulation and distal stimulation to induce local effect or distal curative effect,employed the cutaneous-visceral reflex to explain the therapeutic effect of acu-moxibustion for visceral disorders,used the viscera-cutaneous reflex to explain the tender point(sensitized region)or Ashi-point,used the"predominant factor mechanism"or excitation transfer of the stimulated non-sensitized cutaneous region close to the diseased locus to explain the painrelief of acupuncture stimulation,used the stimulation strength,duration,frequency and distance(to the locus)to explain the needling reinforcing or reducing effect,and so on and so forth.He wrote many articles and books about acupuncturology,one of which was named Jianyao Zhenjiu Xue(Concise Acupuncturology),a well-known demonstration teaching material for advanced training courses,inducing a significant influence on the acu-moxibustion field in both academic field and clinical practice.Looking back this period of history may provide a helpful reference for current research on academic development of acupuncturology.
