ABSTRACT
The great anti-epidemic spirit is a magic weapon for the Chinese people to fight against the COVID-19. Taking the Dr. Zha’s Diary of Fighting the COVID-19 as an example to explore the practical basis and scientific connotation of the great anti-epidemic spirit is of great significance for telling Chinese stories and transmitting Chinese spirit. The anti-epidemic experience described in the book reflects the professional qualities of medical staff who are people-oriented and life first in the fight against the epidemic, the overall view of respecting science and precise prevention and control by various forces in society, and the overall pattern of national unity and shared destiny in China, vividly interprets the precious connotation of the new era medical and health professional spirit.
ABSTRACT
This study aimed to explore the mechanism of Xiaoyao San(XYS) in the treatment of three diseases of liver depression and spleen deficiency, ie, depression, breast hyperplasia, and functional dyspepsia, and to provide a theoretical basis for the interpretation of the scientific connotation of "treating different diseases with the same method" of traditional Chinese medicines. Traditional Chinese medicine systems pharmacology database and analysis platform(TCMSP) was used to screen the active components of XYS which underwent principal component analysis(PCA) with the available drugs for these three diseases to determine the corresponding biological activities. The targets of XYS on depression, breast hyperplasia, and functional dyspepsia were obtained from GeneCards, TTD, CTD, and DrugBank databases. Cytoscape was used to plot the "individual herbal medicine-active components-potential targets" network. The resulting key targets were subjected to Kyoto encyclopedia of genes and genomes(KEGG) pathway analysis and gene ontology(GO) enrichment analysis. A total of 121 active components of XYS and 38 common targets in the treatment of depression, breast hyperplasia, and functional dyspepsia were collected. The key biological pathways were identified, including advanced glycation and products(AGEs)-receptor for advanced glycation and products(RAGE) signaling pathway in diabetic complications, HIF-1 signaling pathway, and cancer-related pathways. The key targets of XYS in the treatment of depression, breast hyperplasia, and functional dyspepsia included IL6, IL4, and TNF, and the key components were kaempferol, quercetin, aloe-emodin, etc. As revealed by the molecular docking, a strong affinity was observed between the key components and the key targets, which confirmed the results. The therapeutic efficacy of XYS in the treatment of diseases of liver depression and spleen deficiency was presumedly achieved by reducing the inflammatory reactions. The current findings are expected to provide novel research ideas and approaches to classify the scientific connotation of "treating different diseases with the same method" of Chinese medicines, as well as a theoretical basis for understanding the mechanism of XYS and exploring its clinical applications.

Recently, the Chinese materia medica (CMM) compatibility theory research was focused on aspect of chemical composition, which is an important strategy to explain the principle of prescriptions. There are various chemical compositions in a compound prescription of CMM, including alkaloids, glycosides, organic acids, tannins, protein, micro elements and so on. Complex interactions always inevitably occur during the water decoction process of CMM prescription after the dissolution of active ingredients, most significantly, it also generates the precipitation. Clinically, traditional Chinese medicines (TCM) treat diseases with both precipitation and decoction. Precipitation generated process might contain the scientific connotation of CMM compatibility. Thus, the scientists had been studying the precipitation from this process. Through summarizing the results of related researches in recent years, this review introduces different interactions of various active ingredients in compound prescriptions and research progress of precipitation in decoction, aiming to lay a foundation for further study on the precipitation from CMM decoction and provide a new idea to explain the theory of CMM compatibility.
ABSTRACT
To establish a method for the determination of three volatile components: menthone, menthol and pulegone in Yinqiao powder (YQP) decoction, explore the change rules of volatile components in decocting process, and provide evidence for elucidating the scientific connotation of its traditional decocting method "taking when the fragrance is volatilized fiercely". YQP decoctions with different decocting time were prepared, and GC-MS was used to qualitatively analyze the volatile components and determine the contents of menthone, menthol and pulegone in decoctions. Then the effects of different decocting time on contents of volatile components were investigated. The results showed that the volatile components in YQP decoctions mainly come from Menthae Haplocalycis Herba, Schizonepetae Herba and Forsythiae Fructus. With the extension of decocting time, the concentrations of all the above 3 volatile components in Yinqiao powder decoction were first increased and then decreased. When soaking for 30 minutes, as well as boiling for 0, 5, 10, 15, 20, 30, 40, 50, 60 minutes, the concentrations of menthone in YQP decoction were 0.058, 0.268, 0.216, 0.073, 0.065, 0.048, 0.048, 0.041, 0.038, 0.034 mg•L ⁻¹; the concentrations of menthol were 0.965, 2.847, 3.633, 2.420, 1.539, 1.189, 1.273, 1.188, 0.905, 0.663 mg•L ⁻¹; the concentrations of pulegone were 0.355, 0.522, 0.598, 0.477, 0.374, 0.374, 0.339, 0.355, 0.248, 0.251 mg•L ⁻¹; and the total concentrations were 1.377, 3.637, 4.446, 2.970, 1.979, 1.611, 1.660, 1.583, 1.191, 0.947 mg•L ⁻¹, respectively. The results showed that the contents of menthone, menthol and pulegone in YQP decoctions were heavily influenced by the decocting time. The fragrance was volatilized fiercely at about 5 minutes after boiling, with larger concentrations of the above three volatile components in decoction; the fragrance got weak after 15 minutes of boiling, the concentrations of menthone, menthol and pulegone in YQP decoctions were significantly decreased, indicating that the traditional decocting method "taking when the fragrance is volatilized fiercely" has some scientific foundation.
ABSTRACT
To establish a method for the determination of chemical specific chromatograms and five components in Yinqiao powder decoction, and provide basis for elucidating the scientific connotation of ″taking in when the fragrance volatilized fiercely″. Yinqiao powder decoctions with different decocting times were prepared to study the changes of chemical components during decocting process. Specific chromatograms and contents of chlorogenic acid, phillyrin, arctiin, liquiritin and glycyrrhizin were determined by high performance liquid chromatography. According to the results, the similarities of Yinqiao powder decoctions with different decocting times were high, which indicated that their chemical compositions were similar. The dissolutions of the five components in Yinqiao powder reached more than 39.7% of 2 hour maximum dissolution amounts (MDA) after 20 minutes of soaking, more than 69.5% of MDA when boiling, more than 79.1% of MDA at the 5th minute after boiling, and more than 85.7% of MDA at the 10th minute after boiling. The concentrations of five components were not increasing obviously after 15 minutes of boiling (RSD<4.3%). The fragrance volatilized fiercely at about the 5th minute after boiling, which indicated that the contents of volatile components in Yinqiao powder decoctions were high, but it became weak after boiling for 15 minutes, which indicated that the contents of volatile components in Yinqiao powder decoctions were low. The results showed that the contents of five components in Yinqiao powder decoctions were heavily influenced by the decocting time. When boiling for about 5 minutes, the fragrance volatilized fiercely, both the contents of volatile components and non-volatile components were high. It is suggested that the traditional decocting method has a certain scientific basis.
