RESUMEN

Introduction: Chronic heart failure (CHF), as the final stage of the progression of many cardiovascular disorders, is one of the main causes of hospitalization and death in the elderly and has a substantial impact on patients' quality of life (QOL). Exercise-based cardiac rehabilitation (CR) has been shown to considerably enhance QOL and prognosis. Given the barriers to center-based CR faced by most developing countries in the form of expensive instruments, the development of home-based CR is necessary. Tai Chi, as an instrument-free exercise, has been shown to be successful in treating elderly CHF individuals. Fu Yang, as one of the academic concept of Traditional Chinese Medicine (TCM), believes that the fundamental pathogenesis of CHF is the gradual decline of Yang, and emphasizes the restoration of Yang physiological function in the treatment process. Therefore, we develope a home-based Tai Chi exercise rehabilitation program called Fu Yang Tai Chi (FYTC) for elderly CHF patients by combining the Fu Yang Theory of TCM with the CR theory. The objective of this study is to evaluate the effectiveness, acceptability, and safety of the program. Methods and analysis: We suggest conducting a parallel randomized controlled clinical trial with open label. Eighty CHF elderly participants will be randomly assigned in a 1:1 ratio to the FYTC rehabilitation program group or the moderate-intensity aerobic walking control group. Eligible participants will engage in either three sessions weekly of FYTC or walking exercise for 12 weeks. The primary outcome is the relative change in 6 min walk distance (6MWD). The secondary outcomes are the plasma levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), QOL, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDd), self-rating anxiety scale (SAS) and depression scale (SDS), exercise skills, and noninvasive hemodynamic monitoring. Throughout the trial, adverse events will be recorded for safety evaluation. Researchers who are blinded to the treatment allocation will analyze the data. Ethics and dissemination: This research was authorized by the Guang'anmen Hospital Ethics Committee of the Chinese Academy of Medical Sciences (2022-141-KY). Our findings will be shared online and in academic conferences as well as in peer-reviewed journals. Trial registration number: ChiCTR2200063511.

RESUMEN

INTRODUCTION: Artemisiae argyi Folium and Artemisiae lavandulaefoliae Folium, two morphologically similar herbal medicines derived from Artemisia genus. Although the two Artemisia herbs have been used as medicines for a long time in China, the study of their phytochemical and bioactive composition is limited. OBJECTIVE: To comprehensively compare and evaluate the composition of Artemisiae argyi Folium and Artemisiae lavandulaefoliae Folium, and find the chemical makers for quality evaluation of the two Artemisia herbal medicines. METHODOLOGY: Eight compounds including six phenolic acids and two flavonoids were assayed by a single reference standard for simultaneous determination of multi-components method using 3-caffeoylquinic acid as the reference standard. The quantitative data were further analysed by chemometric approaches to compare and distinguish the two herbal medicines. RESULTS: The credibility and feasibility of the single reference standard for simultaneous determination of the multi-components method were carefully validated. The validated method was applied to analyse 16 batches of Artemisiae argyi Folium and 10 batches of Artemisiae lavandulaefoliae Folium samples. The quantitative results showed that 3,5-di-O-caffeoylquinic acid was the most abundant constituent, and the contents of flavonoids were notably different between the two herbal medicines. The chemometric analysis results indicated the two flavonoids, jaceosidin and eupatilin could be used as chemical markers for quality evaluation of the two herbal medicines. CONCLUSION: The single reference standard for simultaneous determination of the multi-components method coupled with chemometrics analysis could be a well-acceptable strategy to compare and evaluate the quality of Artemisiae argyi Folium and Artemisiae lavandulaefoliae Folium.

RESUMEN

Artemisiae Argyi Folium, the dried leaves of Artemisia argyi, has been widely used in traditional Chinese and folk medicines for treatment of hemorrhage, pain, and skin itch. Phytochemical studies indicated that volatile oil, organic acid and flavonoids were the main bioactive components in Artemisiae Argyi Folium. Compared to the volatile compounds, the research of nonvolatile compounds in Artemisiae Argyi Folium are limited. In the present study, an accurate and reliable fingerprint approach was developed using HPLC for quality control of Artemisiae Argyi Folium. A total of 10 common peaks were marked,and the similarity of all the Artemisiae Argyi Folium samples was above 0.940. The established fingerprint method could be used for quality control of Artemisiae Argyi Folium. Furthermore, an HPLC method was applied for simultaneous determination of seven bioactive compounds including five organic acids and two flavonoids in Artemisiae Argyi Folium and Artemisiae Lavandulaefoliae Folium samples. Moreover, chemometrics methods such as hierarchical clustering analysis and principal component analysis were performed to compare and discriminate the Artemisiae Argyi Folium and Artemisiae Lavandulaefoliae Folium based on the quantitative data of analytes. The results indicated that simultaneous quantification of multicomponents coupled with chemometrics analysis could be a well-acceptable strategy to identify and evaluate the quality of Artemisiae Argyi Folium.

RESUMEN

Rhizoma Anemarrhena, a widely used traditional Chinese medicine, has previously been shown to have neuroprotective effect. Sarsasapogenin-AA13 (AA13) is a novel synthetic derivative of Sarsasapogenin, which is extracted from Rhizoma Anemarrhena. The aim of this study is to investigate the nootropic and neurotrophic effects of AA13 and underlying mechanisms. In vitro, cell viability of rat primary astrocytes treated with AA13 and neurons cultured with conditioned medium of AA13-treated rat primary astrocytes was tested by MTT assays. In vivo, a pharmacological model of cognitive impairment induced by scopolamine was employed and spatial memory of the mice was assessed by Morris water maze. This study found that AA13 increased cell viability of primary astrocytes and AA13-treated astrocyte-conditioned medium enhanced the survival rate of primary neurons. Interestingly, AA13 markedly enhanced the level of BDNF in astrocytes. Furthermore, AA13 (6 mg/kg) improved the cognitive deficits in animal models (p<0.05) and BDNF and PSD95 levels were increased in brain. Therefore, we hypothesize that AA13 exerts nootropic and neurotrophic activities through astrocytes mediated upregulation of BDNF secretion. The results suggest that AA13 could be a potential compound for cognitive impairment after further research.

RESUMEN

To study the correlation between the content of saikosaponins ingredient of Bupleuri Radix and topographic factors, we researched the ecology suitability regionalization of topographic of Bupleuri Radix from Hebei province to provide a scientific basis for selecting artificial planting. Based on 43 samples of Bupleuri Radix from Hebei province, the variation of the content of saikosaponins in different conditions of topographic factors and the influence of slope, altitude and aspect were comprehensively analyzed by SPSS 21.0. Then we studied topographic factors of ecology suitability regionalization of Bupleuri Radix on the basis of the relationship between the saikosaponins and topographic factors by ArcGIS. The most suitable conditions of topographic for cultivation of saikosaponins are as follows:altitude 600 m above, slope 4.00-5.50 degrees, aspect to the sun. In Hebei province, it is suitable for growth of Bupleuri Radix in the Taihang Mountains and the Yanshan Mountains where the content of saikosaponins is higher.
