Research on acupuncture and glial cells: A bibliometric analysis.

BACKGROUND: There are a growing number of studies on the effect of acupuncture on glial cells in the central nervous system; however, there are few related bibliometric analyses in this area. Therefore, the purpose of this bibliometric study was to visualize the literature on acupuncture-regulated glial cells. METHODS: On November 23, 2022, regular and review articles on acupuncture and glial cell-related research were retrieved from the Web of Science Core Collection database. The R package "bibliometrix" was used to summarize the main findings, count the occurrences of the top keywords, visualize the international collaboration network, and generate a 3-field plot. The VOSviewer software was used to conduct both co-authorship and co-occurrence analyses. CiteSpace was used to identify the best references and keywords with the highest citation rates. RESULTS: Overall, 348 publications on acupuncture and glial cells were included. The publications were primarily from China, Korea, and the United States of America. The majority of publications were found in relevant journals. Apart from "acupuncture" and "glial cells," the most frequently used keywords were "neuroinflammation," "hyperalgesia," and "pain." CONCLUSION: This bibliometric study mapped a fundamental knowledge structure comprising countries, institutions, authors, journals, and articles in the research fields of acupuncture and glial cells over the last 3 decades. These results provide a comprehensive perspective on the wider landscape of this research area.

Interface states and optical coupling functionalities in the super-SSH lattices.

We theoretically address the coupling between trimer lattices and reveal the existence of stable multiple edge and interface states. It is shown the superlattice can provides a tunable number of topologically protected edge and interface states depending on the coupling strength and topological phase of the connecting lattices. Dynamics and transport properties of interface states are also investigated, Due to the interference of linear modes with different propagation constants, stable oscillations resulted from the coupling of interface states in finite trimerized waveguide arrays are observed and can give rise to optical coupling functionalities, including directional coupling, beam splitting and beam oscillator.

Piezo channels in the intestinal tract.

The intestine is the largest mechanosensitive organ in the human body whose epithelial cells, smooth muscle cells, neurons and enteroendocrine cells must sense and respond to various mechanical stimuli such as motility, distension, stretch and shear to regulate physiological processes including digestion, absorption, secretion, motility and immunity. Piezo channels are a newly discovered class of mechanosensitive ion channels consisting of two subtypes, Piezo1 and Piezo2. Piezo channels are widely expressed in the intestine and are involved in physiological and pathological processes. The present review summarizes the current research progress on the expression, function and regulation of Piezo channels in the intestine, with the aim of providing a reference for the future development of therapeutic strategies targeting Piezo channels.
