Infralimbic-basolateral amygdala circuit associated with depression-like not anxiety-like behaviors induced by chronic neuropathic pain and the antidepressant effects of electroacupuncture.

Chronic pain, such as neuropathic pain, can lead to anxiety, depression, and other negative emotions, thereby forming comorbidities and increasing the risk of chronic pain over time. Both the infralimbic amygdala (IL) and the basolateral amygdala (BLA) are significantly associated with negative emotions and pain, and they are known to have reciprocal connections. However, the role of IL-BLA circuit pathways in neuropathic pain-induced anxiety and depression remains unexplored.

Electroacupuncture inhibited carrageenan-induced pain aversion by activating GABAergic neurons in the ACC.

Pain aversion is an avoidance response to painful stimuli. Previous research has indicated that the anterior cingulate cortex (ACC) is involved in pain aversion processing. However, as interneurons, the role of GABAergic neurons in the ACC (GABA neurons) in pain aversion is still unclear.

Modulation of Comorbid Chronic Neuropathic Pain and Anxiety-Like Behaviors by Glutamatergic Neurons in the Ventrolateral Periaqueductal Gray and the Analgesic and Anxiolytic Effects of Electroacupuncture.

Comorbid chronic neuropathic pain and anxiety is a common disease that represents a major clinical challenge. The underlying mechanisms of chronic neuropathic pain and anxiety are not entirely understood, which limits the exploration of effective treatment methods. Glutamatergic neurons in the ventrolateral periaqueductal gray (vlPAG) have been implicated in regulating pain, but the potential roles of the vlPAG in neuropathic pain-induced anxiety have not been investigated.

Electroacupuncture Alleviates Hyperalgesia and Anxiety-Like Behaviors in Pain Memory Model Rats Through Activation of GABAergic Neurons and GABA Receptor in the Rostral Anterior Cingulate Cortex.

Recent studies have confirmed that pain memory is often accompanied by negative emotions. Electroacupuncture (EA) can block the retrieval of painful memories, thereby alleviating the associated negative behaviors. However, the underlying mechanism is poorly understood.

Studies on Pain Associated with Anxiety or Depression in the Last 10 Years: A Bibliometric Analysis.

Background: The prevalence of pain comorbid and anxiety/depression in clinical observations has been high, and the number of related publications has increased in recent years. Nevertheless, few studies have used bibliometric methods to analyze the scientific research on comorbid pain and depression/anxiety. The aim of this study was to systematically examine the trends in global scientific research on comorbid pain and depression/anxiety from 2012 to 2022.

Electroacupuncture alleviates the relapse of pain-related aversive memory by activating KOR and inhibiting GABAergic neurons in the insular cortex.

Pain-related aversive memory is common in chronic pain patients. Electroacupuncture has been demonstrated to block pain-related aversive memory. The insular cortex is a key region closely related to aversive behaviors.

Electroacupuncture Inhibits Pain Memory and Related Anxiety-Like Behaviors by Blockading the GABA Receptor Function in the Midcingulate Cortex.

Pain memory is commonly considered an underlying cause of chronic pain and is also responsible for a range of anxiety. Electroacupuncture (EA) has been shown to ameliorate pain memories and exert anti-anxiety effects. Previous research has indicated that GABAergic neurons and/or GABA receptors (GABARs) in the midcingulate cortex (MCC) have potential associations with chronic pain and anxiety.

Electroacupuncture Regulates Pain Transition Through Inhibiting PKCε and TRPV1 Expression in Dorsal Root Ganglion.

Many cases of acute pain can be resolved with few side effects. However, some cases of acute pain may persist beyond the time required for tissue injury recovery and transit to chronic pain, which is hard to treat. The mechanisms underlying pain transition are not entirely understood, and treatment strategies are lacking.

Electroacupuncture inhibits the interaction between peripheral TRPV1 and P2X3 in rats with different pathological pain.

Chronic pain is regarded to be one of the common and refractory diseases to cure in the clinic. One hundred Hz electroacupuncture (EA) is commonly used for inflammatory pain and 2 Hz for neuropathic pain possibly by modulating the transient receptor potential vanilloid subtype 1 (TRPV1) or the purinergic P2X3 related pathways. To clarify the mechanism of EA under various conditions of pathological pain, rats received a subcutaneous administration of complete Freund's adjuvant (CFA) for inflammatory pain and spared nerve injury (SNI) for neuropathic pain.

Objective: To systematically evaluate the efficacy and safety of conventional therapy combined with moxibustion in the treatment of chronic obstructive pulmonary disease (COPD) in stable phase based on Meta-analysis medicine.

Methods: The randomized controlled trials (RCTs) of moxibustion as adjuvant therapy for COPD were retrieved from the databases of CNKI, Wanfang, SinoMed, PubMed, Web of Science, Cochrane Library and Ebsco. RevMan5.

Acupuncture and related therapies for treating stable angina pectoris: A protocol of an overview of systematic reviews and meta-analysis.

Background: Stable angina pectoris (SAP) is a global health challenge. Multiple previous systematic reviews (SRs) have been conducted to assess the effectiveness of acupuncture and related therapies on SAP. We will carry out a comprehensive overview to map, synthesize, and assess the all the available evidence of acupuncture and related therapies on SAP.

Infrared thermography in the diagnosis of musculoskeletal injuries: A protocol for a systematic review and meta-analysis.

Background: Musculoskeletal injuries (MSDs) have become a major public health problem worldwide. Current diagnosis techniques for MSDs are often associated with radiation exposure, expensive cost, or contraindication. Infrared thermography (IRT) is becoming a proposed tool to assist in diagnosing MSDs, but current evidence is inconclusive.

Electroacupuncture Regulates Pain Transition by Inhibiting the mGluR5-PKCε Signaling Pathway in the Dorsal Root Ganglia.

Background: Acute pain can transition to chronic pain, presenting a major clinical challenge. Electroacupuncture (EA) can partly prevent the transition from acute to chronic pain. However, little is known about the mechanisms underlying the effect of EA.

Electroacupuncture Alleviates Pain-Related Emotion by Upregulating the Expression of NPS and Its Receptor NPSR in the Anterior Cingulate Cortex and Hypothalamus.

Objective: Electroacupuncture (EA) is reported effective in alleviating pain-related emotion; however, the underlying mechanism of its effects still needs to be elucidated. The NPS-NPSR system has been validated for the involvement in the modulation of analgesia and emotional behavior. Here, we aimed to investigate the role of the NPS-NPSR system in the anterior cingulate cortex (ACC), hypothalamus, and central amygdala (CeA) in the use of EA to relieve affective pain modeled by complete Freund's adjuvant- (CFA-) evoked conditioned place aversion (C-CPA).

Electroacupuncture suppresses the pain and pain-related anxiety of chronic inflammation in rats by increasing the expression of the NPS/NPSR system in the ACC.

Background: The neuropeptide S/Neuropeptide S receptor (NPS/NPSR) system is involved in the regulation of anxiety in rodents. Chronic inflammation can induce anxiety. Our lab has observed that electroacupuncture (EA) has a beneficial effect on chronic inflammatory pain and pain-related anxiety; however, the mechanism should be further clarified.

[Advances of researches on peripheral PKCε pathway during transformation from acute to chronic pain and possibility of application of electroacupuncture intervention].

Protein kinase Cε (PKCε) is a transforming oncogene and plays an important role in many cellular processing. In the present paper, we review the development of experimental researches on the acute-chronic pain transformation. Results indicated that prostaglandin E2 (PGE2) / EP1 receptor-Gq-PKCε is an important signaling pathway to modulate chronic pain in peripheral dorsal root ganglion (DRG) neurons, and also plays a role in the later stage of hyperalgesia during transformation from acute to chronic pain.

Electroacupuncture Stimulation Alleviates CFA-Induced Inflammatory Pain Via Suppressing P2X3 Expression.

Chronic inflammatory pain is one of the most common complaints that seriously affects patients' quality of life. Previous studies have demonstrated that the analgesic effect of electroacupuncture (EA) stimulation on inflammatory pain is related to its frequency. In this study, we focused on whether the analgesic effects of EA are related to the period of stimulation.

[Professor ' clinical experience in the treatment of primary cervical dystonia].

Professor ' clinical experience in the treatment of primary cervical dystonia based on the syndrome differentiation of TCM was explored preliminarily. Based on the disease identification of western medicine and the syndrome differentiation of TCM, in combination with the differentiations of meridians and collaterals of acupuncture, Professor proposes the three-dimensional system of diagnosis and treatment of acupuncture, named "disease differentiation, TCM syndrome differentiation and meridian differentiation". Regarding the diagnosis and treatment of primary cervical dystonia, the physical examination of nerve system, TCM syndrome differentiation and meridian differentiation are equally important.
