Exploring global research status and trends in anti-obesity effects of traditional Chinese medicine through intestinal microbiota: a bibliometric study.

Background: The intestinal microbiota (IM) has been found to contribute to metabolic disorders that lead to excessive fat accumulation, systemic and chronic low-grade inflammation, and insulin resistance in the host. Current research highlights a pivotal interaction between IM and traditional Chinese medicine (TCM) in mitigating obesity-related diseases. Undeniably, IM stands as a central focus in TCM research aimed at preventing and treating obesity. Therefore, tracing the progress and trends in this field can offer valuable references and insights for future studies. Methods: On June 17, 2023, we conducted a literature search on the topic of "IM and obesity in TCM" spanning the period from 2009 to 2023. We extracted the primary information of the publications, which includes complete records and reference citations, from the Science Citation Index Expanded (SCI-E) within the Web of Science Core Collection (WoSCC). To visualize and analyze the literature, we utilized CiteSpace and VOSviewer for bibliometric analysis. Results: During the past fifteen years, a rapid increase in the number of publications has been observed. The cooperative networks demonstrate China, Beijing University of Chinese Medicine, and Food & Function as the most active countries, organizations, and journals in this field, respectively. Liu Bin has contributed the most publications. A paper by Xu Jia, published in 2014, holds the highest Local Citation Score (LCS). Analyses of keyword co-occurrence and reference co-citation indicate that the research hotspots of IM and obesity in TCM are primarily focused on the metabolic benefits driven by endogenous functional metabolic molecules generated by TCM regulation of IM. Other focal points include the mechanism by which TCM regulates IM to restore the intestinal mucosal barrier This is a provisional file, not the final typeset article, and manages the gut-organ axis, the metabolic advantages of acupuncture's regulation of IM, and the process by which Chinese medicine small molecules transform IM. Conclusion: This research offers a comprehensive understanding of the current status, hotspots, and trends in global TCM research. Additionally, it provides a comprehensive summary and exploration of the latest advancements in this field, thereby emphasizing the essence of TCM more effectively.

[Research on Dynamic Evolution of Blockade of Heart Vessel Syndrome Based on Metabonomics].

Objective To observe the changes of metabolomics in the evolution process of blockade of heart vessel syndrome (BHVS). Methods The formation of BHVS in three stages were sim- ulated by using high-fat forage and ligating the left anterior descending coronary artery. Increased blood lipid was in the early stage of blood stasis syndrome (BSS) group. Atherosclerosis (AS) was formed in the middle stage of BSS group (sub-BSS). Coronary artery was ligated on the basis of AS was the 3rd stage of BSS (BHVS group). There were 8 rats in each group. Totally 24 rats was used as the blank con- trol group and each stage had 8 rats. The changes of metabolite contents were analyzed using principal component analysis (PCA) and partial least squares method (PLS) with gas chromatography-mass spectrometer (GC-MS) among different groups. Results (1) In the 32 kinds of identified metabolites, citric acid was closest associated with the evolution process of BHVS, followed by cholesterol, inositol, ornithine, proline, isoleucine, octadecanoic acid, lactic acid, urea, leucine, linoleic acid, mannose. (2) Metabolic markers in the three stages: octadecanoic acid, lactic acid (positively correlated) , and mannose (negatively correlated) in the early stage of BSS. Ornithine, proline, inositol (positively correla- ted) , and isoleucine (negatively correlated) in the middle stage of BSS (sub-BSS). Leucine, isoleucine, citric acid (positively correlated) , and lactic acid (negatively correlated) in the BHVS stage. Conclusions High fat diet causes disordered in vivo lipid metabolism in pre-stage BSS, and the organism initiates anti- inflammation. Continued high fat diet leads to disordered urea cycle, imbalanced intestinal flora, changed vascular morphology, and liver dysfunction in the sub-BSS stage. Acute myocardial ischemia leads to glucose metabolism disorder in the BHVS stage.
