Abstract
Primary dysmenorrhea is a common gynecological disease with typical clinical symptoms and diverse treatment methods. Acupoint patch therapy is one of the traditional external treatments of traditional Chinese medicine, with a long history, and has been widely used in the treatment of many diseases in China. Graphene nuangong acupoint plaster (GNGAP) developed based on traditional acupoints and new materials have been used in the clinical treatment of primary dysmenorrhea, and satisfactory therapeutic effects have been achieved. However, the underlying mechanisms of GNGAP still need further investigation. In this study, we used estradiol benzoate combined with oxytocin intraperitoneally to establish dysmenorrhea model rats, and observed the torsion response, uterine organ coefficients, prostaglandin levels and metabolite changes of rats with dysmenorrhea model after the intervention of GNGAP, to elucidate the mechanism of the effect of GNGAP. Compared with normal rats, the dysmenorrhea model rats exhibited increased writhing response and latency time, increased uterine organ coefficient, and significant changes in 79 metabolites. Twenty-three significantly enriched pathways were discovered, including amino acid metabolism, arachidonic acid metabolism, pyrimidine metabolism, and ovarian steroidogenesis, which may be involved in the pathogenesis of primary dysmenorrhea. Compared with the model group, the torsion response, latency time and uterine organ coefficient of rats in the acupoint patch group were significantly improved, and nine uterine metabolites were significantly altered, among which metabolites such as 4-pyridoxic acid, d-glucarate and Phenol were identified as potential biomarkers for the therapeutic effects of GNGAP. Vitamin B6 metabolism, Ascorbate and aldarate metabolism and Tyrosine metabolism were enriched in nine metabolic pathways. These findings contribute to the screening study of potential pathological metabolic pathways in primary dysmenorrhea. Additionally, they reveal the biological effects of GNGAP in the treatment of primary dysmenorrhea at the metabolite level.

Chen B, Guo Q, Zhang Q, Di Z, Zhang Q. Revealing the Central Mechanism of Acupuncture for Primary Dysmenorrhea Based on Neuroimaging: A Narrative Review. Pain Res Manag 2023; 2023:8307249. [PMID: 36852393 PMCID: PMC9966569 DOI: 10.1155/2023/8307249] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 12/29/2022] [Accepted: 01/17/2023] [Indexed: 02/20/2023]
Abstract
Objective The central mechanism of acupuncture for primary dysmenorrhea was explored by summarizing the changes in different regional networks of the brain induced by acupuncture stimulation by analyzing the existing studies. Methods The original studies were collected and selected from three English databases such as PubMed and four Chinese databases as China Knowledge Network (CNKI). The main keyword clusters are neuroimaging, acupuncture, and primary dysmenorrhea. Results The literature review yielded 130 possibly qualified studies, and 23 articles fulfilled the criteria for inclusion. Regarding the type of acupuncture studies, 6 moxibustion studies and 17 manual acupuncture studies for primary dysmenorrhea were included. Based on functional magnetic resonance imaging (fMRI), perfusion-weighted imaging (PWI), and positron emission tomography-computer tomography techniques (PET-CT), one or more analysis methods such as amplitude of low-frequency fluctuations (ALFF), regional homogeneity (ReHo), functional connectivity (FC), and independent components analysis (ICA) were used. The results are summarized. To summarize the high-frequency brain area alterations observed in patients with acupuncture-induced primary dysmenorrhea were the anterior cingulate gyrus, thalamus, insula, precentral gyrus, middle frontal gyrus, postcentral gyrus, putamen, and cerebellum. Conclusion The results suggest that the mechanism of acupuncture in the treatment of primary dysmenorrhea is the involvement of networks regulating different areas of the brain in the analgesic effects of acupuncture. The brain regions involved in primary dysmenorrhea acupuncture analgesia were mainly located in the pain matrix, default mode network, salience network, and limbic system.

Quant Imaging Med Surg 2023; 13:1071-1082. [PMID: 36819245 PMCID: PMC9929379 DOI: 10.21037/qims-22-683] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Accepted: 11/27/2022] [Indexed: 12/24/2022]
Abstract
Background Neuroimaging studies have identified altered brain structures and functions in women with primary dysmenorrhea (PDM). However, previous studies focused on either structural or functional changes in specific brain regions rather than combining structural and functional analysis. Therefore, this prospective cross-sectional study aimed to investigate the changes in whole brain structure, and functional variation along with structural abnormalities in women with PDM during menstruation. Methods In all, 31 patients with PDM (PTs) and 31 healthy controls (HCs) were recruited. Voxel-based morphometry (VBM) and surface-based morphometry (SBM) analyses were applied to investigate structural changes based on high-resolution T1-weighted magnetic resonance images. Functional connectivity (FC) analysis was performed to evaluate functional variations related to the brain regions that showed structural group differences. Pearson correlation analysis was performed to assess the relationship between neuroimaging changes and clinical measures. Results Compared to HCs, PTs had reduced gray matter volume (GMV) in the right superior temporal gyrus (STG) and reduced thickness in the bilateral orbitofrontal cortex (OFC), left postcentral gyrus (PoCG), and left superior occipital gyrus (SOG). Among these areas, the STG and PoCG are responsible for altered resting-state FC patterns in PTs. Results showed decreased FC between the STG and the left cerebellar posterior lobe (poCb), the right dorsolateral prefrontal cortex (DLPFC), and the left precentral gyrus (PrCG). Results also showed decreased FC between the PoCG and the right precuneus and the right DLPFC. We also found greater FCs between the PoCG and the bilateral poCb, the left middle temporal gyrus (MTG), and the left angular gyrus. In addition, the FCs between the STG and poCb, and DLPFC in PTs were positively correlated with history and Cox menstrual symptom scale (CMSS) scores, respectively, while the FCs between STG and PrCG were negatively correlated with the onset age of PDM. Conclusions Our research found structural abnormalities and related FC changes in several brain regions that were mainly involved in the emotional and sensory aspects of menstrual pain in PDM. These findings could help us understand the occurrence of PDM from a neuroimaging perspective.

[PMID: 36950556 PMCID: PMC10026736 DOI: 10.3389/fonc.2023.1077961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Accepted: 02/10/2023] [Indexed: 03/08/2023] Open
Abstract
Background The number of publications on acupuncture for cancer pain is increasing rapidly with an upward tendency. Considering that no bibliometric articles related to this topic have been published yet. It is necessary to evaluate the global scientific output of research in this field, and shed light on the direction of clinical cancer pain management in the future. Methods Research publications regarding acupuncture on cancer pain from inception to 2022 were downloaded from the Web of Science Core Collection. Bibliometric analyses were performed using CiteSpace software, the bibliometrix R package, and VOSviewer software. Network maps were generated to assess the collaborations between different countries, institutions, authors, and keywords. And clusters map was generated to evaluate reference. Results A total of 790 articles related to acupuncture therapy for cancer pain were identified. We observe that the number of publications is gradually increasing over time. China and the United States were the main contributors. Mem Sloan Kettering Canc Ctr (38 papers) and Beijing Univ Chinese Med (28 papers) contributed the most publications, becoming the leading contributors in this field. Although J Clin Oncol (28 articles) ranked ninth in terms of publication volume, it was the journal with the most citations and the highest number of IF (50.717) and H-index (494) at the same time. MAO J from Mem Sloan Kettering Canc Ctr was the most prolific author (23 articles). The main hot topics included matters related to acupuncture (239 times), pain (199 times), management (139 times), quality of life (107 times), electroacupuncture (100 times), and breast cancer (82 times). Conclusion Our bibliometric analysis provides a comprehensive overview of the development of acupuncture for cancer pain, enabling relevant authors and research teams to identify the current research status in this field. At the same time, acupuncture for breast cancer (BC) pain, aromatase inhibitor-induced arthralgia (AIA), and chemotherapy-induced peripheral neuropathy (CIPN) may soon become prospective focus.
