Objective:To optimize the extraction process of Ziyin Qinggu Pills.Methods:The solvent amount, extraction time and soaking time were taken as the influencing factors, and the overall desirability (OD) of the contents of timosaponin BⅡ, paeoniflorin, calycosin 7-O-glucoside, liquiritin and the dry extract yield were taken as the evaluation indexes, so that the optimal extraction process of Ziyin Qinggu Pills was optimally selected by the centralized composite design-response surface method.Results:The optimal extraction process of Ziyin Qinggu Pills was as follows: extraction time of 115 min, soaking time of 26 min, solvent volume of 10 times, and extraction twice.Conclusion:The optimal extraction process is reasonable, stable and reliable, which can provide the basis and foundation for the extraction process and further molding process of Ziyin Qinggu Pills.

Objective To optimize the optimal extraction process for phthalein and phenolic acid components in Angelicae Sinensis Radix-Chuanxiaong Rhizoma decoction pieces.Methods On the basis of a single factor experiment,central combination design-response surface methodology was adopted,and the extraction time,ethanol concentration,and ethanol dosage were used as influencing factors,and the total normalized values of the content of Senkyunolide I,Senkyunolide A and ligustilide,and extract yield were used as evaluation indicators to optimize the extraction process of phthalein components in Angelicae Sinensis Radix-Chuanxiaong Rhizoma decoction pieces;the total normalized values of chlorogenic acid,caffeic acid,ferulic acid,and extract yield were used as evaluation indicators to optimize the extraction process of phenolic acids components in Angelicae Sinensis Radix-Chuanxiaong Rhizoma decoction pieces.Results The optimal extraction process was to add 7 times the amount of 90%ethanol to the phthalein components,extract for 130 minutes each time,and extract twice;phenolic acid components were extracted twice with 7.5 times the amount of 65%ethanol for 120 minutes each time.Conclusion The optimized extraction process for phthalein and phenolic acids in Angelicae Sinensis Radix-Chuanxiaong Rhizoma decoction pieces is stable and feasible,which can provide a basis for subsequent research.

Objective Based on the multi-software visual analysis of the literature on the effect of Janus kinase(JAK)/signal transducer and activator of transcription(STAT)signaling pathway on rheumatoid arthritis in the past decade,the development trend and research hotspot in this field are summarized.To provide researchers with new directions and ideas to promote the innovative development of the field.Methods The literatures related to JAK/STAT signaling pathway in rheumatoid arthritis were collected from the Web of Science Core Collection database from 2013 to 2023.CiteSpace and VOSviewer software were used to analyze the number of publications,countries,authors and keywords of 354 articles retrieved.Results The number of published papers in this field continues to increase.According to the author's research direction,the presentation of high-frequency words,and the attention to the preface and hot topics,it is suggested that this field focuses on gene expression,immune mechanism,inflammatory mechanism,pathway inhibitors,drug therapy,etc.Future research will focus on the safety,mechanism and controlled trials of pathway inhibitors and antirheumatic drugs.Conclusion The effect of JAK/STAT signaling pathway on rheumatoid arthritis has attracted much attention in the past,present and future.There are differences in the research of different teams in this field,and the regional development is unbalanced,suggesting that we should strengthen cooperation and exchanges,focus on the international frontier,and carry out more high-quality research to promote the development and progress of this field,and provide clinical basis.

Objective To analyze the current status and trends of TCM regulation of microRNA(miRNA)using visualization methods.Methods The literature related to the TCM regulation of miRNA was retrieved from CNKI,VIP and Wanfang Data from the establishment of the databases to May 31,2022.Excel 2019,VOSviewer 1.6.18,and CiteSpace 5.8.R3 software were applied to visualize and analyze the year of publication,journal source,author and keywords of the included literature.Results A total of 787 articles were included,and the number of publications continued to rise.Source journals with more publications includes Chinese Journal of Experimental Traditional Medical Formulas,China Journal of Traditional Chinese Medicine and Pharmacy,Chinese Archives of Traditional Chinese Medicine,etc.Research teams were formed with Wang Jie,Liu Xide,Diao Limei,etc.as the representatives,and the cooperation among the teams was not very close.Analysis on the keywords in the literature showed that the studies mainly focused on apoptosis,miRNA-21,electroacupuncture,atherosclerosis,proliferation and other related fields;TCM intervention that accounted for the most research were extracts of Chinese materia medica,with 42%of the studies;there were 24 miRNAs studied≥3 times,and the most studied miRNA was miRNA-21.Conclusion The research hotspots of TCM regulation of miRNA are mainly the molecular mechanism of various TCM therapeutic tools to improve cell autophagy,apoptosis,inflammatory response and other pathways through regulation of miRNAs.The trend of research is to study the mechanism of empirical prescriptions of famous TCM practitioners based on precise therapeutic strategies.
