BACKGROUND

Acupuncture has gained increasing international attention in recent decades. The act of incorporating acupuncture treatment into the routine treatment of COVID-19 in China drove us to review the 100 most influential articles of the last 20 years to learn about the current status and trends of acupuncture.

METHOD

Articles related to acupuncture from January 1, 2001, to July 4, 2022, were searched in the Clarivate Analytics Web of Science Core Collection database. The top 100 most cited publications were selected, and information was extracted. Software such as VOSviewer, GraphPad Prism, Scimago Graphica, and CiteSpace were used to visualize and analyze the extracted data.

RESULT

The 100 most cited articles were identified, with an average of 218 citations (range: 131-625). The majority of the top 100 articles were from the USA (n = 53). The institution that published the most highly cited papers was Harvard University (n = 16). The most influential team was Klaus Linde's group. Pain was the top-ranked journal in terms of the number of publications. The largest clusters for co-occurrence keyword analysis focused on acupuncture and electroacupuncture analgesia and brain imaging responses to acupuncture stimulation via functional MRI. The two highest strength burst keywords were "randomized controlled trials" and "osteoarthritis," with "randomized controlled trials" being a consistent burst keyword from 2011 to the present.

CONCLUSION

This study provides insight into articles of historical significance in the field of acupuncture through bibliometric analysis. These data should provide clinicians and researchers with insight into future directions related to acupuncture.

Acupuncture attenuates comorbid anxiety- and depressive-like behaviors of atopic dermatitis through modulating neuroadaptation in the brain reward circuit in mice

Atopic dermatitis (AD) is highly comorbid with negative emotions such as anxiety and depression. Although acupuncture has demonstrated efficacy in AD, its influence on comorbid anxiety and depression remains unclear. We sought to explore the impact and mechanisms of action of acupuncture on comorbid anxiety and depression of AD. AD-like skin lesions were induced by the topical application of MC903 to the mouse cheek. Acupuncture was performed at Gok-Ji (LI11) acupoints. AD-like phenotypes were quantified by lesion scores, scratching behavior, and histopathological changes. The effects of acupuncture on comorbid anxiety and depression-like behaviors were assessed using the elevated plus-maze (EPM), open-field tests (OFT), and tail-suspension test (TST). In addition, biochemical changes in the brain reward regions were investigated by immunoblotting for the expression of tyrosine hydroxylase (TH), dopamine D1 receptor (D1R), phospho-dopamine and cAMP-regulated phosphoprotein-32 kDa (pDARPP-32), phospho-cAMP response element binding protein (pCREB), ΔFosB, and brain-derived neurotrophic factor (BDNF) in the nucleus accumbens, dorsolateral striatum, and ventral tegmental area. Acupuncture effectively improved the chronic itching and robust AD-like skin lesions with epidermal thickening. Additionally, it considerably reduced comorbid anxiety- and depression-like symptoms, as indicated by more time spent in the open arms of the EPM and in the center of the open field and less time spent immobile in the TST. Higher pCREB, ΔFosB, BDNF, and pDARPP-32 levels, and reduced TH and D1R protein expression in the brain reward regions of AD mice were reversed by acupuncture treatment. The beneficial effects of acupuncture on clinical symptoms (scratching behavior) and comorbid psychological distress in AD strongly correlated with dorsal striatal ΔFosB levels. Collectively, these data indicate that acupuncture had a significant, positive impact on comorbid anxiety- and depression-like behaviors by modulating neuroadaptation in the brain reward circuit in mice with AD, providing a novel perspective for the non-pharmacological management of psychiatric comorbidities of AD.

Comparative Study of Classical and Alternative Therapy in Dogs with Allergies

Simple Summary

Acupuncture, phytotherapy, and nutrition are part of traditional Chinese medicine, which has been used for literally hundreds to a few thousand years. These traditional therapeutic methods can effectively diagnose and treat acute and chronic diseases and can be used as a primary or complementary therapy. Used properly, these alternatives are safe and without side effects. Allergy is currently a very common diagnosis affecting dogs. Conventional Western medicine can treat symptoms but often does not identify and resolve the underlying problem. This comparative study was focused on the application of alternative and conventional medicine in allergic conditions in dogs, which were divided into two groups, where the effectiveness of both types of treatment was compared.

Abstract

Allergy is a malfunction of the immune system that causes an inappropriate reaction to normally harmless substances known as allergens, such as food components, pollen, parasites, mites, medication, etc. It is very important to make a correct diagnosis, to identify and to eliminate the offending allergen from the body, and provide control and long-term management to achieve a comfortable life for the animal. In the case of highly intensive pruritus, drugs such as glucocorticoids, antihistamines, and Janus kinase inhibitors are generally administered. Unfortunately, common drugs are not always able to resolve the problem. This comparative clinical-outcomes study focused on the application of alternatives, where a combination of acupuncture with phytotherapy and nutrition was applied. These traditional methods do not affect the body only symptomatologically; instead, they treat the patient as a whole. In this clinical study, the therapeutic effects and partial or complete stabilization of the allergic condition of fourteen dogs divided into two groups were observed, compared, and evaluated.

Acupuncture for the Treatment of Itch: Peripheral and Central Mechanisms

Despite the widespread clinical use of acupuncture in the treatment of pruritus caused by psoriasis, urticaria, uremic, and other diseases, insights into the mechanism of action of acupuncture are still emerging. For the above reasons, a beneficial effect of acupuncture on pruritus was not recommended or reported in recent clinical practice guidelines. Acupuncture is a kind of physical stimulation, which has the characteristics of multi-channel and multi-target effects. The biomechanical stimulation signal of acupuncture needling can be transformed into bioelectric and chemical signals; interfere with kinds of cells and nerve fibers in the skin and muscle; alter signaling pathways and transcriptional activity of cells, mediators, and receptors; and result in inhibition of peripheral and central transmission of pruritus. Available mechanistic data give insights into the biological regulation potency of acupuncture for pruritus and provide a basis for more in-depth and comprehensive mechanism research.

Efficacy of acupuncture treatment for chronic spontaneous urticaria: study protocol for a randomised controlled trial

INTRODUCTION

Chronic spontaneous urticaria (CSU) is a troublesome dermatological problem that can have a significant impact on quality of life. Previous studies have indicated that acupuncture may be beneficial for patients with CSU. However, well-designed studies determine the effects of acupuncture on CSU are rare. The aim of this study is to investigate the efficacy and safety of acupuncture treatment for patients with CSU.

METHODS AND ANALYSIS

This study is designed as a multicentre, parallel, three-arm, randomised, sham-controlled trial. A total of 330 patients diagnosed as CSU will be randomly allocated into three groups: the verum acupuncture group, the sham acupuncture group and the waiting-list control group in a 1:1:1 ratio. Patients in the verum and sham acupuncture groups will receive 16 treatment sessions over 4 weeks, while patients in the waiting-list control group will not receive any acupuncture treatment. The primary outcome is the changes of weekly urticaria activity scores at the end of treatment. Secondary outcomes include itching severity measurement, Dermatology Life Quality Index, Hamilton Depression Scale, Hamilton Anxiety Scale, Pittsburgh Sleep Quality Index and serum total IgE level. Adverse events will be recorded during the study observation period. All patients who are randomised in this study will be included in the intention-to-treat analysis.

ETHICS AND DISSEMINATION

Ethical approval of this study has been granted by the Sichuan Regional Ethics Review of Committee on Traditional Chinese Medicine (TCM) (ID: 2019 kl-006), the Medical Ethic Committee of the First Hospital of Wuhan (ID: (2019) number 7)) and the Medical Ethics Committee of the First Hospital of Hunan University of TCM (ID: HN-LLKY-2019-017-01/03) in three clinical centres in China, respectively. The results will be disseminated through peer-reviewed journals.

Acupuncture: A therapeutic approach against acne

Acne is a common but chronic skin disease that influence large population especially juvenile. Acne can continue, begin, or grow into severe form in adult age, affecting face, back, and chest. It may be a serious issue if not cared or treated timely. Even if acne got treated it leaves a persistent scar, which is difficult to alleviate. These acne lesions are long-lasting and result in significant impact on mental and physical health of an individual. There are four mechanisms that are involved in acne lesion formation. However, the accurate series of events of the interaction among the factors in acne pathogenesis is still unsettled. Pubescent acne is due to increase hormone levels, when in fact adult acne is due to fluctuation in hormone levels. There are various approaches for the treatment of acne, including oral medications, creams or gels, acupuncture. Traditional Chinese Medicine stated acne as a infection that is associated with the pathogenic influence of damp heat and heat on specific meridians. As an ancient and integral part of Chinese medicine acupuncture therapy is employed in the treatment of many diseases including acne. It functions by ameliorating the deep-rooted mechanisms playing crucial role in acne development. In this review, we have explained the acne causes, pathogenesis, and its available treatment options. Additionally, we also discussed the acupuncture therapy methods, devices, different techniques. and its mechanism of action in treating acne. Furthermore, clinical trials studies motivated us to highlight the scope of acupuncture in the growing system of medicine.

Electroacupuncture Regularizes Gastric Contraction and Reduces Apoptosis of Interstitial Cells of Cajal in Diabetic Rats

Background/Aims

Gastric dysmotility is a frequent complication among patients with diabetes mellitus. Electroacupuncture (EA) has been empirically used to relieve gastrointestinal symptoms. The aims of this study were to investigate the effects of EA on gastric contraction and the mechanisms of interstitial cells of Cajal (ICC) involved.

Materials and Methods

Male Sprague–Dawley rats were randomized into the normal control, diabetes (DM), diabetic and sham EA (DM + SEA), diabetic and low-frequency EA (DM + LEA), and diabetic and high-frequency EA (DM + HEA) groups. Diabetic models were established and then treated with EA for 8 weeks. Body weight and blood glucose were recorded every 2 weeks. The spontaneous contractions of distal gastric strips were analyzed. Immunostaining and RT-PCR were used to test the apoptotic ICC, IGF-1/IGF-1R, and Nrf2/HO-1 pathways.

Results

The body weight in the DM + LEA and DM + HEA groups were increased compared with that of the DM group, though there was no effect on the blood glucose. The gastric contractions were obviously disordered in the DM group, but EA could regularize the contractions. The number of apoptotic ICC was dramatically increased in the DM group, but reduced with EA treatment. Meanwhile, the IGF-1/IGF-1R pathway was verified to be significantly altered in diabetic rats. The Nrf2/HO-1 pathway was not significantly increased in the DM group. EA with different frequencies efficiently improved the expression of IGF-1/IGF-1R signaling and activated the Nrf2/HO-1 pathway.

Conclusion

EA could improve gastric motility dysfunction and attenuate ICC apoptosis possibly through the regulation of IGF-1/IGF-1R and Nrf2/HO-1 pathways. EA may be a potential therapeutic method for diabetic gastric motility dysfunction.

Acupuncture ameliorates not only atopic dermatitis-like skin inflammation but also acute and chronic serotonergic itch possibly through blockade of 5-HT2 and 5-HT7 receptors in mice

Acupuncture has been known to be effective for atopic dermatitis, especially ameliorating itch; however, its mechanisms are still unclear. The aim of this study was to test the anti-itch effects of acupuncture and to investigate its possible mechanisms. Acupuncture was performed at Gok-Ji (LI11) acupoints just before the injection of pruritogens in the mouse cheek model of acute itch and of MC903-induced atopic dermatitis displaying serotonergic chronic itch. Acupuncture significantly reduced acute itch triggered by compound 48/80, chloroquine, or especially serotonin. It also markedly reduced scratching behaviors evoked by the serotonin 5-HT₂ receptor agonist α-methylserotonin and selective 5-HT₇ receptor agonist LP 44. In addition, acupuncture treatment at LI11 had the preventive and therapeutic effects on persistent itch as well as the robust skin inflammation with epidermal thickening in mice with MC903-induced atopic dermatitis. It also considerably reduced the increased expression of 5-HT_2A, 5-HT_2B and 5-HT₇ receptors in atopic dermatitis-like skin lesions in mice treated with MC903. Taken together, these findings highlight that acupuncture significantly ameliorates not only skin inflammation, but also acute and chronic serotonergic itch, possibly through blockade of serotonin 5-HT₂ and 5-HT₇ receptors.

S2k guidelines for the treatment of psoriasis in children and adolescents - Short version part 2

The present guidelines are aimed at residents and board-certified physicians in the fields of dermatology, pediatrics, pediatric dermatology and pediatric rheumatology as well as policymakers and insurance funds. They were developed by dermatologists and pediatric dermatologists in collaboration with pediatric rheumatologists using a formal consensus process (S2k). The guidelines highlight topics such as disease severity, quality of life, treatment goals as well as problems associated with off-label drug therapy in children. Trigger factors and diagnostic aspects are discussed. The primary focus is on the various topical, systemic and UV-based treatment options available and includes recommendations for use and treatment algorithms. Other aspects addressed herein include vaccinations in children and adolescents with psoriasis as well as various disease subtypes such as guttate psoriasis, diaper psoriasis, pustular psoriasis and psoriatic arthritis. Finally, we also provide recommendations for imaging studies and the diagnostic workup to rule out tuberculosis prior to initiating systemic treatment. Note: This article constitutes part 2 of the Sk2 guidelines for the treatment of psoriasis in children and adolescents. Part 1 was published in last month's issue. It contained introductory remarks and addressed aspects of diagnosis and topical treatment.

Treating the patient not the symptoms: Acupuncture to improve overall health - Evidence, acceptance and strategies

Documented mechanisms of acupuncture suggest the possibility of whole body effects in addition to local and regional effects. Traditional theories of acupuncture predict whole body effects. Does this permit the possibility of applying treatment to target overall health improvement of the patient rather than the symptom? After introducing the term 'health improvement' this paper explores situations where it might be advantageous to do this, giving examples of how health authorities in some countries have proposed broader treatment approaches that focus on health improvement. It also discusses cases where acupuncture has been recommended as a treatment method in a number of these proposals and gives some clinical examples of this kind of whole body 'health improvement' targeted treatment effects. Given that health authorities have already recognised this potential for the application of acupuncture the author then explores evidence of more whole-body 'health improvement' effects from systematic reviews and examples of health experts recommending acupuncture to take advantage of them. Research strategies and foci are then proposed and explored to develop this evidence. What are the best treatment approaches to create these effects? By what mechanisms can 'health improvement' be produced? How can one measure these effects? It is likely that treatments based on 'pattern identification' (PI) may provide the best strategies for producing 'health improvement', thus PI-based acupuncture treatments are likely to be the best strategy for clinical research investigating these effects.

Effects of acupuncture on chronic idiopathic pruritus: an uncontrolled pilot study evaluating inflammatory changes with treatment

Background Conduct a pilot study addressing the efficacy of acupuncture in the treatment of chronic idiopathic pruritus to aid in the design of a larger clinical trial. Routine laboratory tests to assess systemic inflammation in addition to subjective patient surveys were performed provide documentation of efficacy of treatment. Methods Patients with chronic pruritus who did not respond to standard treatment were recruited to participate. After exclusion of systemic or known reversible causes, each patient received up to 10 treatments which were performed approximately one week apart. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured before and after a series of acupuncture treatments to evaluate levels of inflammation and pre- and post-treatment surveys were conducted to evaluate levels of perceived itch. Results Only one of the ten patients in this study possessed an elevation of ESR before treatment. This patient's ESR value returned to normal range after treatment and this participant reported subjective relief of her pruritus. Conclusions Future studies on the efficacy of acupuncture in the treatment of chronic idiopathic pruritus should focus on those patients with measurable levels of inflammation at the initiation of the study or utilize alternative and more comprehensive values to monitor disease response.
