Evaluation of clinical efficacy of silver-needle warm acupuncture in treating adults with acute low back pain due to lumbosacral disc herniation: study protocol for a randomized controlled trial

Attenuation of immobilization stress-induced hypertension by temperature-controllable warm needle acupuncture in rats and the peripheral neural mechanisms

Introduction

We and others have shown that electrical stimulation of the PC-6 acupoint over the wrist relieves hypertension by stimulating afferent sensory nerve fibers and activating the central endogenous opioid system. Warm needle acupuncture has long been utilized to treat various diseases in clinics.

Methods

Here, we developed a temperature-controllable warm needle acupuncture instrument (WAI) and investigated the peripheral mechanism underlying the effect of warm needle acupuncture at PC-6 on hypertension in a rat model of immobilization stress-induced hypertension.

Results

Stimulation with our newly developed WAI and traditional warm needle acupuncture attenuated hypertension development. Such effects were reproduced by capsaicin (a TRPV1 agonist) injection into PC-6 or WAI stimulation at 48°C. In contrast, PC-6 pretreatment with the TRPV1 antagonist capsazepine blocked the antihypertensive effect of WAI stimulation at PC-6. WAI stimulation at PC-6 increased the number of dorsal root ganglia double-stained with TRPV1 and CGRP. QX-314 and capsaicin perineural injection into the median nerve for chemical ablation of small afferent nerve fibers (C-fibers) prevented the antihypertensive effect of WAI stimulation at PC-6. Additionally, PC-6 pretreatment with RTX ablated the antihypertensive effect of WAI stimulation.

Conclusion

These findings suggest that warm needle acupuncture at PC-6 activates C-fiber of median nerve and the peripheral TRPV1 receptors to attenuate the development of immobilization stress-induced hypertension in rats.

Similarities and differences between kaiy in Persian medicine and moxibustion in Chinese medicine

Kaiy (medieval cautery) is an ancient method of heat therapy in traditional Persian medicine (TPM). Some of its important applications have been neglected during the medical revolution. Meanwhile, different treatment modalities that incorporate heat, including moxibustion, have progressed in traditional Chinese medicine. In this study, we reviewed the main TPM textbooks that were written specifically in the field of kaiy. We considered the traditional teachings in the context of contemporary information, gathered from the scientific literature about moxibustion and modern cauterization. Some surgical therapeutic indications of kaiy (e.g., debridement and coagulative procedures) have been advanced by the innovation of electro-cauterization. However, those therapeutic applications that were based on the TPM humoral theory for relieving body coldness or myofascial pains-which are similar to moxibustion usages-have not received the same attention. Apart from the broad similarities of kaiy and moxibustion as thermal therapies with similar indications, there is a striking correspondence between kaiy point mapping and acupoints. Therefore, further research on different kaiy aspects is recommended. Please cite this article as: Jaladat AM, Alizadeh Vaghasloo M, Atarzadeh F, Ayati MH, Kazemi AH, Akin E, Hashempur MH.

Rare, fatal pulmonary fat embolism after acupuncture therapy: A case report and literature review

BACKGROUND

Death from nontraumatic pulmonary fat embolism associated with minor soft tissue contusion, surgery, cancer chemotherapy, hematologic disorders and so on has been reported. Patients often present with atypical manifestations and rapid deterioration, making diagnosis and treatment difficult. However, there are no reported cases of death from pulmonary fat embolism after acupuncture therapy. This case emphasizes that the stress induced by acupuncture therapy, a mild soft tissue injury, plays an important role in pulmonary fat embolism. In addition, it suggests that in such cases, pulmonary fat embolism as a complication of acupuncture therapy needs to be taken seriously, and autopsy should be used to identify the source of fat emboli.

CASE PRESENTATION

The patient was 72 years old female and experienced dizziness and fatigue after silver-needle acupuncture therapy. She experienced a significant drop in blood pressure and died 2 h later despite treatment and resuscitation. A systemic autopsy and histopathology examination (H&E and Sudan Ⅲ staining) were performed. More than 30 pinholes were observed in the lower back skin. Focal hemorrhages were seen surrounding the pinholes in the subcutaneous fatty tissue. Microscopically, numerous fat emboli were observed in the interstitial pulmonary arteries and alveolar wall capillaries, in addition to the vessels of the heart, liver, spleen and thyroid gland. The lungs showed congestion and edema. The cause of death was identified as pulmonary fat embolism.

CONCLUSION

This article suggests that high vigilance for risk factors and the complication of pulmonary fat embolism following silver-needle acupuncture therapy should be exercised. In postmortem examinations, it should be pay attention that the peripheral arterial system and the venous system draining from non-injured sites should be examined for the formation of fat emboli, which can help distinguish posttraumatic and nontraumatic pulmonary fat embolism.

Herbal Formula Modified Bu-Shen-Huo-Xue Decoction Attenuates Intervertebral Disc Degeneration via Regulating Inflammation and Oxidative Stress

Objective

This study aims to clarify the potential mechanism of modified Bu-Shen-Huo-Xue decoction (MBSHXD) in treating intervertebral disc degeneration (IDD) with methods of network pharmacology and molecular docking.

Methods

An MBSHXD and IDD-related common target gene set was established through TCMSP, UniProt, and two disease gene databases. GO and KEGG enrichment analysis and protein-protein interaction (PPI) networks were performed through the R platform and STRING to discover the potential mechanism. Molecular docking between the active ingredients and the core genes is used to calculate the binding energy.

Results

A total of 147 active ingredients and 79 common genes (including 10 core genes, TNF, VEGFA, IL6, MAPK3, AKT1, MAPK8, TP53, JUN, MMP9, and CXCL8) were identified. The results of GO and KEGG enrichment analysis showed that MBSHXD plays an essential role in regulating inflammation and oxidative stress. The meaningful pathways are the AGE-RAGE signaling pathway in diabetic complications, the IL-17 signaling pathway, the TNF signaling pathway, the PI3K-Akt signaling pathway, the MAPK signaling pathway, and apoptosis. In addition, the PPI network and molecular docking further demonstrated the roles that nine bioactive ingredients of MBSHXD play in IDD treatment through their interference with core target proteins.

Conclusion

This study reveals that MBSHXD has the characteristics of a “multi-component, multi-target, and multi-pathway” in the treatment of IDD by regulating inflammation and oxidative stress, and network pharmacology may provide a feasible method to verify the molecular mechanism of MBSHXD for IDD by combining with molecular docking.

Knowledge Mapping Analysis of International Research on Acupuncture for Low Back Pain Using Bibliometrics

Objective

Acupuncture has made recommendations to relieve low back pain (LBP) in a few guidelines. However, few articles focused on the papers published before, which may reflect the trend of study, main researchers, reciprocal collaboration, and other information in this field. In this study, we utilize the bibliometric analysis methods to objectively analyze the current trend and research hotspots about this field, aiming to provide a foundation and reference for future study.

Methods

The Web of Science database was searched for publications related to acupuncture therapy for treating low back pain between 1985 and 2021. VOSviewer and CiteSpace were used to analyze the annual publication, authors and co-cited authors and their countries (regions) and institutions, journals and co-cited journals, co-cited references, co-occurrence keywords, burst keywords, and the relevant centrality.

Results

A total of 1279 papers were retrieved from the database, and the trend of annual publications maintained growth. Article was the most document type (867). The USA (451) and the Kyung Hee University (49) were the most productive country (region) and institution, respectively, while the USA (0.37) and University of Maryland (0.13) had the highest centrality. MacPherson, Hugh and Sherman, Karen J. published the most papers in this field (32), and Ernst, Edzard became the most influential author (474 co-citations). Journal of Alternative and Complementary Medicine was the most productive journal (79), whereas SPINE was the most influential one (3111 co-citations). Haake's (2007) article had the most co-citation count (186), while Furlan's (2005) article had the highest centrality (0.23). The three frontier topics were pain management, disease, and protocol.

Conclusion

The present study investigated publications on acupuncture for treating low back pain using bibliometric analysis methods, which may help researchers explore the potential directions for the future.

The Role of Acupuncture in Interventional Pain Management

Objective: Interventional pain management has been recognized over the last couple of decades for treating chronic-pain syndromes. Acupuncture is a nonpharmacologic therapeutic option for pain management and may be an option for different patients with contraindications for interventional pain management. This review explores this options. Method: This limited review examines the role of acupuncture for managing head-and-neck pain and lower-back pain, according to interventional pain management. Conclusions: Acupuncture at various points, corresponding to the stellate ganglion, which is ST 10 Shuitu, and corresponding to the splanchnic nerve and the facet joint of the lumbar vertebra-which are Ex-B2 paravertebra-can be applied for pain management in the head-and-neck area and in the lower-back area. According to various research findings, acupuncture is effective and safe for reducing pain in the head and neck area, as well as in the lower back.

Acupuncture for the Management of Low Back Pain

PURPOSE OF REVIEW

This evidence-based systematic review will focus on the use of acupuncture and its role in the treatment of low back pain to help better guide physicians in their practice. It will cover the background and the burden of low back pain and present the current options for treatment and weigh the evidence that is available to support acupuncture as a treatment modality for low back pain.

RECENT FINDINGS

Low back pain (LBP), defined as a disorder of the lumbosacral spine and categorized as acute, subacute, or chronic, can be a debilitating condition for many patients. Chronic LBP is more typically defined by its chronicity with pain persisting > 12 weeks in duration. Conventional treatment for chronic LBP includes both pharmacologic and non-pharmacologic options. First-line pharmacologic therapy involves the use of NSAIDs, then SNRI/TCA/skeletal muscle relaxants, and antiepileptics. Surgery is usually not recommended for chronic non-specific LBP patients. According to the 2016 CDC Guidelines for Prescribing Opioids for Chronic Pain and the 2017 American College of Physicians (ACP) clinical practice guidelines for chronic pain, non-pharmacologic interventions, acupuncture can be a first-line treatment for patients suffering from chronic low back pain. Many studies have been done, and most show promising results for acupuncture as an alternative treatment for low back pain. Due to non-standardized methods for acupuncture with many variations, standardization remains a challenge.

The treatment of intervertebral disc degeneration using Traditional Chinese Medicine

ETHNOPHARMACOLOGICAL RELEVANCE

Intervertebral disc degeneration (IDD) is one of the most common causes of chronic low back pain that spending a lot of workforces and financial resources, seriously affecting human physical and mental health. Clinically used drug treatments and surgical treatments cannot fundamentally relieve the disease and have a risk of recurrence. Traditional Chinese Medicine (TCM) has a history of more than a thousand years in the prevention and treatment of IDD. However, so far, there are few reviews on the treatment of IDD by TCM. Therefore, it is crucial and necessary to systematically mine the existing literature on the treatment of IDD with TCM. This paper strives to systematically describe the modern medicine and TCM theoretical research on IDD, progress in the treatment of IDD and focuses on the treatment of IDD by TCM, which would lay some theoretical foundation and provide new directions for future research.

MATERIALS AND METHODS

Information on clinical observations, animal experiments and relevant pharmacology data about the treatment of IDD were gathered from various sources including traditional Chinese books and Chinese Pharmacopoeia, scientific databases (Elsevier, PubMed, Science Direct, Baidu Scholar, CNKI, Spring Link, Web of Science) and from different professional websites.

RESULTS

This review mainly introduces the current research on the theoretical research on IDD, the combination principle of the TCM formula, and the underlying mechanism of the formula and active ingredients.

CONCLUSIONS

At present, domestic and foreign scholars have carried out a lot of research in different ways, such as the molecular mechanism and predisposing factors of IDD, which provides theoretical development and clinical practice significance for future research. TCM, as a multi-component and multi-targeted drug, can produce synergistic effects to exert its efficacy. Therefore, the development of TCM with more specific functions and practical data will not only become a significant trend in the world market but also has an irreplaceable role in the future treatment of IDD.
