Key targets of signal transduction neural mechanisms in acupuncture treatment of cardiovascular diseases: Hypothalamus and autonomic nervous system

Background

Cardiovascular disease is the leading cause of death worldwide. As a traditional Chinese treatment method, acupuncture has a unique role in restoring the balance of the human body environment. Due to its safety, non-invasive nature, and effectiveness in treating cardiovascular diseases, acupuncture has been widely welcomed and recognized among the world. A large amount of evidence shows that acupuncture can effectively regulate cardiovascular diseases through the autonomic nervous system. The hypothalamus, as an important component of regulating the autonomic nervous system, plays an important role in regulating the internal environment, maintaining homeostasis, and preserving physiological balance. However, there is currently a scarcity of review articles on acupuncture signal transduction and acupuncture improving cardiovascular disease through the hypothalamus and autonomic nervous system.

Objective

This review delves into the transduction of acupuncture signals and their neural regulatory mechanisms on the hypothalamus and autonomic nervous system, elucidating their impact on cardiovascular disease.

Methods

Review the basic and clinical studies on acupuncture signal transduction mechanisms and the role of the hypothalamus and ANS in acupuncture treatment of cardiovascular diseases published in four English databases (PubMed, Web of Science, MEDLINE, and Springer Cochrane Library) and two Chinese databases (Wanfang Database and China National Knowledge Infrastructure Database) over the past 20 years.

Results

Through sensory stimulation, acupuncture effectively transmits signals from the periphery to the hypothalamus, where they are integrated, and finally regulate the autonomic nervous system to treat cardiovascular diseases.

Discussion

Acupuncture exhibits significant potential as a therapeutic modality for cardiovascular diseases by orchestrating autonomic nervous system regulation via the hypothalamus, thereby gifting novel perspectives and methodologies for the prevention and treatment of cardiovascular ailments.

The impact of physical therapy on dysphagia in neurological diseases: a review

A neurogenic dysphagia is dysphagia caused by problems with the central and peripheral nervous systems, is particularly prevalent in conditions such as Parkinson's disease and stroke. It significantly impacts the quality of life for affected individuals and causes additional burdens, such as malnutrition, aspiration pneumonia, asphyxia, or even death from choking due to improper eating. Physical therapy offers a non-invasive treatment with high efficacy and low cost. Evidence supporting the use of physical therapy in dysphagia treatment is increasing, including techniques such as neuromuscular electrical stimulation, sensory stimulation, transcranial direct current stimulation, and repetitive transcranial magnetic stimulation. While initial studies have shown promising results, the effectiveness of specific treatment regimens still requires further validation. At present, there is a lack of scientific evidence to guide patient selection, develop appropriate treatment regimens, and accurately evaluate treatment outcomes. Therefore, the primary objectives of this review are to review the results of existing research, summarize the application of physical therapy in dysphagia management, we also discussed the mechanisms and treatments of physical therapy for neurogenic dysphagia.

Systematic review and meta-analysis of the efficacy and safety of electroacupuncture for poststroke dysphagia

Introduction

Optimal treatment strategies for post-stroke dysphagia (PSD) remain to be explored. Electroacupuncture (EA) has attracted widespread attention due to its simplicity, cheapness, and safety. However, the efficacy of EA in the treatment of PSD lacks high-level evidence-based medical support. This study aimed to systematically evaluate the clinical value of EA in the treatment of PSD.

Methods

A total of seven databases were searched for relevant literature. All randomized controlled trials (RCTs) on EA alone or EA combined with other interventions for the treatment of PSD were assessed using the modified Jadad scale. The studies with a score of ≥4 were included. The quality of the included studies was then assessed using the Cochrane Collaboration's tool. The meta-analysis was performed using Rev. Man 5.3 software.

Results

Twelve studies involving 1,358 patients were included in the meta-analysis. Meta-analysis results showed that the EA group was superior to the control group in terms of clinical response rate (OR = 2.63, 95% CI = 1.97 to 3.53) and videofluoroscopic swallowing study (VFSS) score (MD = 0.73, 95% CI = 0.29 to 1.16). There was no significant difference between the two groups in the standardized swallowing assessment (SSA) score (MD = -3.11, 95% CI = -6.45 to 0.23), Rosenbek penetration-aspiration scale (PAS) score (MD = -0.68, 95% CI = -2.78 to 1.41), Swallowing Quality of Life (SWAL-QOL) score (MD = 13.24, 95% CI = -7.74 to 34.21), or incidence of adverse events (OR = 1.58, 95% CI = 0.73 to 3.38).

Conclusion

This study shows that EA combined with conventional treatment or other interventions can significantly improve the clinical response rate and VFSS score in patients with PSD without increasing adverse reactions.Systematic review registration: https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=396840.
