Efficacy of acupoint injection in the treatment of chronic eczema and its influence on peripheral blood T cells

BACKGROUND Chronic eczema significantly impacts daily life,social interactions,and quality of life;however,no curative treatment has been identified.AIM To determine the clinical efficacy of acupoint injection for chronic eczema and its influence on peripheral blood T cells.METHODS Eighty patients with chronic eczema treated at our hospital between June 2022 and March 2023 were randomly assigned to a control group(n=40),which received conventional Western medicine treatment,or an observation group(n=40),which received routine Western medicine treatment plus acupoint injection of triamcinolone acetonide.Response and adverse reaction rates,as well as differences in the levels of serum cytokines IFN-γ,IL-2,IL-4,and IL-10 before and after treatment were investigated.RESULTS No difference in overall response rates were found between the observation and control groups(100%vs 90%,respectively;P>0.05);however,the observation group had a higher marked response rate than the control group(87.5%vs 52.5%;P<0.05).Both groups had decreased Eczema Area and Severity Index scores and increased pruritus after treatment(P<0.05),particularly in the observation group(P<0.05).The observation group had an adverse reaction rate of 2.5%(1/40),which did not differ significantly from that of the control group(P>0.05).The observation group exhibited higher post-treatment INF-γand IL-2 but lower IL-4 levels than the control group(P<0.05);however,no significant inter-group difference was observed in post-treatment IL-10 levels(P>0.05).CONCLUSION Acupoint injection of triamcinolone acetonide is safe and effective in treating chronic eczema.Its therapeutic mechanism is related to the regulation of peripheral blood T cell levels,inhibition of inflammatory reactions,and mitigation of immune imbalance.

Mechanism of acupoint penetration acupuncture therapy regulating chondrocyte autophagy via the PI3K/Akt-mTOR pathway in KOA rats

Objective To investigate whether acupoint penetration acupuncture(APA)could regulate chondrocyte autophagy and apoptosis via the PI3K/Akt-mTOR signaling pathway to reduce cartilage degeneration in knee osteoarthritis(KOA)rats.Methods KOA was induced in rats via intra-articular injection of sodium iodoacetate resolution.Forty male Sprague-Dawley rats were randomly assigned to blank control,model,APA,electro-acupuncture(EA),and sham model groups(n=8)and those in the APA and EA groups received their respective therapies.Following completion of the treatment course,histological examinations of cartilage and muscle were conducted.Levels of apoptosis-and autophagy-related factors,including Bax,Bcl-2,mTOR,ULK-1,and Beclin-1 protein,and mRNAs were assessed.Additionally,β-endorphin(β-EP)concentrations in the brain and serum were measured.Results Histological analysis revealed that APA alleviated cartilage and muscle damage compared with the model group.APA inhibited cartilage degeneration by modulating the expression of apoptosis-and autophagy-related proteins and mRNA,thus preventing chondrocyte apoptosis.In the APA group,Bax and mTOR protein levels were significantly lower than those in the model group(both P=.024).Conversely,the Bcl-2 expression level was significantly higher than that in the EA group(P=.035).Additionally,ULK-1 expression was significantly lower than that in the EA group(P=.045).The mRNA level of Bax was significantly higher than that in the blank control group(P<.001).However,Beclin-1 levels were significantly higher than those in both the model and EA groups(both P<.001).ELISA results showed a significant decrease in the concentration ofβ-EP in the brains of the rats in the APA group compared with those in the model group(P=.032).Conclusions APA reduced osteoarthritis-related pain and alleviated cartilage damage by upregulating chondrocyte autophagy and down-regulating apoptosis via signaling pathways involving PI3K/Akt-mTOR in KOA rats.

Analysis of acupoint massage combined with touch on relieving anxiety and pain in patients with oral implant surgery

BACKGROUND Oral implant surgery is an effective procedure for artificial implants in missing tooth areas under local anesthesia.Because patients under local anesthesia are conscious during this procedure,compared with general anesthesia-related operations,they are more likely to experience negative emotions,such as anxiety and tension.These emotional reactions result in shivering and chills in the limbs,leading to poor doctor-patient cooperation and even avoidance of treatment.In traditional Chinese medicine,it is believed that acupoint massage regulates blood and Qi,dredge menstruation,and relieve pain,which is beneficial for patients’emotional adjustment;however,there are few related clinical studies.AIM To observe the changes in anxiety and pain in patients with oral implant after acupoint massage combined with touch therapy.METHODS One hundred patients undergoing oral implantation in our hospital between May 2020 and May 2023 were randomly divided into control and study groups,according to a random number table,with 50 patients in each group.The control group received routine intervention,and the study group received acupoint massage combined with touch on the basis of the control group.Anxiety[assessed using the Modified Dental Anxiety Scale(MDAS)],pain severity,blood pressure,heart rate,and satisfaction were compared between the two groups.RESULTS Before intervention,the difference in MDAS score between the two groups was not significant(P>0.05),while after the intervention,the MDAS scores decreased in both groups compared with those before the intervention(P<0.05);the MDAS score of the study group was lower than that of the control group,with a statistically significant difference(P<0.05).The degree of pain in the intervention group was significantly lower than that in the control group(P<0.05).Before the intervention,there were no significant differences in systolic and diastolic blood pressures or heart rate between the two groups(P>0.05).The systolic and diastolic blood pressures and heart rate in the intervention group,during and after the intervention,were significantly lower than those in the control group(P<0.05).The total degree of satisfaction in the study group was significantly higher than that in the control group(P<0.05).CONCLUSION Acupoint massage combined with touch better relieves anxiety and pain in patients undergoing dental implant surgery,improving the perioperative comfort of these patients and ensuring safety and a smooth operation.

Acupoint catgut-embedding therapy ameliorates DNCB-induced atopic dermatitis in BALB/c mice by regulating Th2 type immune response and reducing infiltration of CD4^(+)and CD8^(+)cells

Background:This study aimed to assess how acupoint catgut-embedding therapy influences Th2-type immune response and the infiltration of CD4^(+)and CD8^(+)cells in DNCB-induced atopic dermatitis in BALB/c mice.It also conducted an initial examination of the underlying molecular mechanisms.Methods:Seventy-two mice were randomly divided into four groups:normal control,DNCB-induced atopic dermatitis model(AD),AD with acupoint catgut-embedding treatment(ADA),and AD with sham-acupoint catgut-embedding treatment.After DNCB challenge to induce AD,the ADA group received acupoint catgut-embedding therapy treatment at Zusanli(ST 36)and Quchi(LI 11)acupoints every other week from day 8.Mice in the AD with sham-acupoint catgut-embedding treatment group underwent the same procedure as the ADA group but without catgut implantation.Severity was assessed using SCORAD on treatment days 1,10,and 20.On day 18,nine mice per group were euthanized,and the remaining on day 28.Histopathological changes were observed using hematoxylin-eosin and immunohistochemistry staining.TNF-α,IL-4,IL-6,and IL-13 levels were analyzed by ELISA,and GATA3 and STAT6 protein levels by western blot.Results:After 20 days of acupoint catgut-embedding therapy treatment,mice showed reduced dermatitis scores compared to DNCB-induced AD-like mice.Significant decreases occurred in serum IL-4,IL-6,IL-13,and TNF-αlevels.Skin analysis revealed marked reductions in CD4^(+)and CD8^(+)cell infiltration,as well as GATA3 and STAT6 protein levels.Conclusion:Acupoint catgut-embedding therapy may effectively alleviate atopic dermatitis by suppressing Th2 immune responses via the STAT6-GATA3 pathway and reducing CD4^(+)and CD8^(+)T cell infiltration in skin lesions.

IMPACTS ON THE EXPRESSION OF VASCULAR ENDOTHELIAL GROWTH FACTOR IN ISCHEMIC BRAIN TISSUE TREATED WITH CLUSTER PUNC-TURE ON SCALP ACUPOINTS IN RATS

Objective To probe into the impacts on the expression of vascular endothelial growth factor （VEGF） in ischemic brain tissue treated with cluster puncture on scalp acupoints in rats, Methods 128 rats were randomized into pseudo-operation group, model group, scalp-needling group and cluster-needling group, In scalp-needling group, penetration method was used on the focal side from Bǎihuì （百会 GV20） to Qǔbīn （曲鬓 GB7）, and in cluster-needling group, penetration method was used on both sides from GV20 to GB7, and a common needling on GV 20. Needles were punctured 2 mm in depth, constantly rotated for 10min, retained for 2 h. Immunohistrochemical method was applied to determine VEGF expression and microvessel density （MVD）. Results With the intervention of cluster puncture on scalp acupoints, VEGF： expressions on every time-spot after ischemia were enhanced apparently, superior to those in scalp-needling group. On the three time-spots of the 7^th, 14^th and 21^st days, MVD was increased after cluster puncture on scale acupoints, superior to those in scalp-needling group. Conclusion Cluster puncture on scalp acupoints up-regulated VEGF expression and promoted regeneration of microvessel.

RELATIONSHIP OF ACUPOINTS AND MERIDIANS TO CONNEXIN 43

Objective To explore the relationship between connexin 43 and acupoints and meridians. Methods we detected one major skin gap junction connexin （connexin43, Cx43） in meridians and acupoints, and studied the expression of Cx43 in Zusanli （足三里 ST 36） acupoints compared with control non-acupoint regions in rats after acupuncture treatments. The expression of Cx43 was detected by using immunohisto- chemistry, immunoblotting, and RT-PCR for Cx43 protein and mRNA level. Results The results showed much more abundant Cx43 expression in some cells in the skin and subcutaneous tissue of rat at ST 36 acupoints and bladder and kidney meridians than that of in the controls. The mRNA and protein levels of Cx43 in acupoints were significantly higher than those of in the control points in non-acupuncture groups and even more so after acupuncture treatments. Conclusion Our research implied that connexins and gap junctions could have a close relationship to acupoints and meridians, and gap junctional intercellular communication might play an important role in the effect of acupuncture.

PRESENT SITUATION OF STUDY AND VIEW ON FUNCTIONAL DYSPEPSIA TREATED WITH SPECIFIC ACUPOINTS IN ACUPUNCTURE

Acupuncture plays a dominant role in treating functional dyspepsia （FD）. By reviewing and e- valuating clinical ROT and fundamental research with high quality in the past 17 years, it is found that specific acupoints are the chief in the treatment of FD; additionally, there are differences between specific acupoints and non-specific acupoints in therapeutic effect, explaining that the specificity of meridian points plays an im- portant role in treatment. However, because of inadequate high-quality researches in clinics, the specificity of acupoints can＇t be proved until the researches of clinical effect and mechanism of therapeutic difference are intensified.

RELATIONSHIP BETWEEN INTERNAL ORGAN(VISCERA) AND ACUPOINTS:TOWARD MERIDIAN THEORY

The theory of interrelation between acupoints and viscera （IBAV） is one of the most important parts in Traditional Chinese Medicine and the key concept in the theory of Zangfu and Jingluo （meridians）. IBAV expresses the rule between body surface and inner organs which guides the diagnosis and treatment in acupuncture practice. Yellow Emperor said. ＂The twelve-channel is the passage of the flowing of the blood and energy in human body, it has close relation with the existence of the flowing of the blood and energy in human body, it has close relation with the existence of man, the forming of disease, the human health and the recovery of disease... ＂ （Chapter 11 Jing Bie Yellow Emperors Canon Internal Medicine） Early studies noted that IBAV is bi-direetional by reflex reaction to the aeupoints on body surface. Stimulation on the acupoints can simultaneously regulate visceral functions. Recent research showed that acupuncture stimulations induced neuronal nitric oxide expression in the brainstem. Nitric Oxide in the medulla medicates various physiological reflexes. In this Review, the evidence of the relationship between viscera and acupoints will be summarized and emphases on the study of interrelation between acupoints and viscera is not only for improving clinical effects, but also for clarifying the mechanisms of acupuncture-moxibustion. A main way to treat visceral illnesses is choosing acupoints based on differentiation of symptoms and signs.

Blood-letting punctures at twelve Jing-Well points of the hand can treat cerebral ischemia in a similar manner to mannitol

A rat model of middle cerebral artery permanent occlusion was established using the modified Longa method. Successfully established model animals were treated by blood-letting puncture at twelve Jing-Well points of the hand, and/or by injecting mannitol into the caudal vein twice daily. Brain tissue was collected at 24, 48 and 72 hours after modeling, and blood was collected through the retinal vein before Evans blue was injected, approximately 1 hour prior to harvesting of brain tissue. Results showed that Evans blue leakage into brain tissue and serum nitric oxide synthase activity were significantly increased in model rats. Treatment with blood-letting punctures at twelve Jing-Well points of the hand and/or injection of mannitol into the caudal vein reduced the amount of Evans blue leakage into the brain tissue and serum nitric oxide synthase activity to varying degrees. There was no significant difference between single treatment and combined treatment. Experimental findings indicate that blood-letting punctures at twelve Jing-Well points of the hand can decrease blood-brain barrier permeability and serum nitric oxide synthase activity in rats following middle cerebral artery occlusion, and its effect is similar to that of mannitol injection alone and Jing-Well points plus mannitol injection.

Improvement in acupoint selection for acupuncture of nerves surrounding the injury site: electro-acupuncture with Governor vessel with local meridian acupoints

Peripheral nerve injury not only affects the site of the injury, but can also induce neuronal apop- tosis at the spinal cord. However, many acupuncture clinicians still focus only on the injury site, selecting acupoints entirely along the injured nerve trunk and neglecting other regions; this may delay onset of treatment efficacy and rehabilitation. Therefore, in the present study, we compared the clinical efficacy of acupuncture at Governor vessel and local meridian acupoints combined （GV/LM group） with acupuncture at local meridian acupoints alone （LM group） in the treatment of patients with peripheral nerve injury. In the GV/LM group （n = 15）, in addition to meridian acupoints at the injury site, the following acupoints on the Governor vessel were stimulated： Baihui （GV20）, Fengfu （GV16）, Dazhui （GV14）, and Shenzhu （GV12）, selected to treat nerve injury of the upper limb, and Jizhong （GV6）, Mingmen （GV4）, Yaoyangguan （GV3）, and Yaoshu （GV2） to treat nerve injury of the lower limb. In the LM group （n = 15）, only me- ridian acupoints along the injured nerve were selected. Both groups had electroacupuncture treatment for 30 minutes, once a day, 5 times per week, for 6 weeks. Two cases dropped out of the LM group. A good or excellent clinical response was obtained in 80% of the patients in the GV/ LM group and 38.5% of the LM group. In a second study, an additional 20 patients underwent acupuncture with the same prescription as the GV/LM group. Electomyographic nerve conduc- tion tests were performed before and after acupuncture to explore the mechanism of action of the treatment. An effective response was observed in 80.0% of the patients, with greater motor nerve conduction velocity and amplitude after treatment, indicating that electroacupuncture on specific Governor vessel acupoints promotes functional motor nerve repair after peripheral nerve injury. In addition, electromyography was performed before, during and after electroacu- puncture in one patient with radial nerve injury. After a single session, the patient＇s motor nerve conduction velocity increased by 23.2%, indicating that electroacupuncture at Governor vessel acupoints has an immediate therapeutic effect on peripheral nerve injury. Our results indicate that Governor vessel and local meridian acupoints used simultaneously promote functional repair after peripheral nerve injury. The mechanism of action may arise from an improvement of the local microenvironment in injured nervous tissue, as well as immediate effects of Governor vessel and local meridian acupoint stimulation to ensure the continuity between the peripheral and central nervous systems.
