Résumé
This study aims to objectively and quantitatively analyze the research status and hot spots of Chuanxiong Rhizoma and provide guidance for further research and clinical application of this herbal medicine. Firstly, the research articles involving Chuanxiong Rhizoma from 2010 to 2023 were retrieved from seven databases including Web of Science, PubMed, Medline, CNKI, VIP, Wanfang, and SinoMed. Then, NoteExpress and manual reading were employed to complete the de-duplication and screening of the articles, and the annual number of publications and journals was analyzed. Finally, CiteSpace was used for systematic analysis of the research institutions, authors, and keywords, and the corresponding knowledge maps were established. After screening, 1 137 articles in Chinese and 433 articles in English were included, and the annual number of publications showed an increasing trend. Chinese Journal of Experimental Traditional Medical Formulae and Journal of Ethnopharmacology were the top Chinese and English journal in the number of publications. Chengdu University of Traditional Chinese Medicine and Nanjing University of Chinese Medicine published the most articles in Chinese and English, respectively. PENG Cheng and FENG Yi were the authors published more articles in Chinese and English. Ferulic acid, signaling pathway, mechanism, headache, ligustrazine, and apoptosis were frequent keywords. A total of 20 clusters and 30 bursts were generated. The comprehensive analysis showed that the research trends and hot spots in this field mainly focused on pharmacological components and isolation, pharmacological effects and mechanism, clinical application and efficacy, compatibility and efficacy of drug pairs, quality evaluation and control, and cultivation and germplasm improvement.

Hypoxic preconditioning could improve the survival of mesenchymal stem cells (MSCs) in ischemic or hypoxic environments, but its exact mechanism remains to be further explored. This study aims to determine the role of lysine crotonylation (Kcr) in regulating the survival and proliferation of peripheral blood mesenchymal stem cells (PBMSCs) in the hypoxic culture. PBMSCs were isolated and cultured from rat peripheral blood mononuclear cells, and their surface markers were identified by flow cytometry. PBMSCs were first subjected to hypoxic/ normoxic preconditioning: hypoxic (1% O
Résumé
Inflammation is the key pathogenic feature of heart failure （HF）， and its overexpression can cause myocardial hypertrophy， apoptosis and fibrosis， aggravating the process of HF. Macrophages are important immune cells in human body with high heterogeneity， which involve in inflammation response and maintain heart homeostasis. Macrophage polarization is a dynamic process. Under the stimulation of different microenvironment， it can polarize two subsets， including classically activated M1 type and alternatively activated M2 type， which are antagonistic to each other. When macrophages polarize into the pro-inflammatory phenotype （M1）， the inflammatory response is initiated， the anti-inflammatory phenotype （M2） plays a role in inhibiting inflammation and repairing tissue. At the same time， in different stages of development of HF， M1 and M2 macrophages can be transformed into each other， which is similar to the connotation of Yin-yang restriction， balance and transformation of traditional Chinese medicine （TCM） theory. Based on this， this paper intends to clarify the relationship between M1 and M2 macrophages by Yin-yang theory， proposing that the clinical prevention and treatment of HF should pay attention to regulating micro and macro inflammatory responses， regulating macrophage polarization， and achieving the balance between anti-inflammatory and pro-inflammation， which is consistent with the balance of Yin-yang in TCM theory. It can provide a new target and direction for TCM treatment of HF.
