Pharmacodynamic Substances and Action Mechanisms of Chaihu Shugansan in Antidepressant Treatment： A Review / 中国实验方剂学杂志

Depression is a kind of complex mental illness， which is mainly treated by western medicine at present， but the effect of western antidepressant drugs is not good due to the combined influence of side effects and individual differences of patients. Depression is a "stagnation syndrome" in traditional Chinese medicine， and its treatment principle is to disperse stagnated liver Qi for relieving Qi stagnation. The classic traditional Chinese medicine formula Chaihu Shugansan （CHSGS） has a long history of treating depression and demonstrates significant therapeutic efficacy. Clinically， the addition and subtraction of CHSGS is flexible， but the properties of the active ingredients are vague， and the mechanism and function are unclear. In order to elucidate the pharmacodynamic basis and antidepressant mechanism of CHSGS， this article reviews the pharmacodynamic material basis of CHSGS， clinical research and antidepressant mechanism research progress. Clinically， CHSGS can treat various types of depression such as primary depression， post-stroke depression， and postpartum depression. This article summarizes 32 main ingredients of CHSGS， among which albiflorin， ferulic acid， naringin， hesperidin， saikosaponin a， glycyrrhetinic acid， tangeretin， meranzin hydrate， nobiletin and glycyrrhizic acid are the quality markers （Q-markers） for the antidepressant effect of CHSGS. The antidepressant mechanism of CHSGS is complex， including regulating monoamine neurotransmitters， hypothalamic-pituitary-adrenal （HPA） axis， neurotrophic factors， inflammatory response， cell damage-related pathways， oxidative stress， etc. This article helps to deeply understand the pharmacodynamic basis and mechanism of CHSGS in treating depression， and provides a theoretical basis for the clinical application of CHSGS in treating depression and the development of antidepressant drugs.

Clinical Application and Quality Analysis of Classical Formula Xiaoyaowan： A Review / 中国实验方剂学杂志

Xiaoyaowan has the effects of soothing the liver， invigorating the spleen， regulating menstruation， and nourishing blood. It is often used to treat the distending pain of the chest and hypochondriac， loss of appetite， dizziness， and irregular menstruation caused by liver depression and spleen deficiency. The formula originated from the Sinisan of Treatise on Cold Damage（《伤寒论》） in the Han dynasty and was officially formulated in the Song dynasty's Taiping Royal Prescriptions（《太平惠民合计局方》）. In the Ming and Qing dynasties， it was developed into more comprehensive formulas such as modified Bazhentang， modified Xiaoyaowan， and other formulas. In recent years， Xiaoyaowan has become a classic formula for treating many symptoms of liver depression. The Pharmacopoeia of the People's Republic of China（《中华人民共和国药典》）， 2020 edition， records Xiaoyaowan and modified Xiaoyaowan. Modern clinical research has further expanded the therapeutic range of this formula. Through literature research， it is found that there are certain reports on the clinical application and quality analysis of Xiaoyaowan， but the relevant literature lacks collation so far. Therefore， relevant literature was consulted and sorted out. The paper summarized the treatment of mammary hyperplasia， depression， irregular menstruation， melasma， menopausal syndrome， and polycystic ovary syndrome with Xiaoyaowan， as well as the quality analysis of paeoniflorin， ferulic acid， and glycyrrhizinic acid of Xiaoyaowan. It is expected to lay a foundation for further research on clinical application， pharmacodynamic mechanism， and quality control of this classic formula.

ETCM v2.0: An update with comprehensive resource and rich annotations for traditional Chinese medicine

Existing traditional Chinese medicine (TCM)-related databases are still insufficient in data standardization, integrity and precision, and need to be updated urgently. Herein, an Encyclopedia of Traditional Chinese Medicine version 2.0 (ETCM v2.0, http://www.tcmip.cn/ETCM2/front/#/) was constructed as the latest curated database hosting 48,442 TCM formulas recorded by ancient Chinese medical books, 9872 Chinese patent drugs, 2079 Chinese medicinal materials and 38,298 ingredients. To facilitate the mechanistic research and new drug discovery, we improved the target identification method based on a two-dimensional ligand similarity search module, which provides the confirmed and/or potential targets of each ingredient, as well as their binding activities. Importantly, five TCM formulas/Chinese patent drugs/herbs/ingredients with the highest Jaccard similarity scores to the submitted drugs are offered in ETCM v2.0, which may be of significance to identify prescriptions/herbs/ingredients with similar clinical efficacy, to summarize the rules of prescription use, and to find alternative drugs for endangered Chinese medicinal materials. Moreover, ETCM v2.0 provides an enhanced JavaScript-based network visualization tool for creating, modifying and exploring multi-scale biological networks. ETCM v2.0 may be a major data warehouse for the quality marker identification of TCMs, the TCM-derived drug discovery and repurposing, and the pharmacological mechanism investigation of TCMs against various human diseases.

To explore the quality markers of Huangqin Qingre Chubi capsule in the treatment of rheumatoid arthritis based on network pharmacology combined with pharmacokinetics and target verification / 药学学报

As an effective prescription for the treatment of rheumatoid arthritis (RA), Huangqin Qingre Chubi capsule (HQC) is still blank in quality control. This study aims to explore quality markers (Q-markers) for HQC in the treatment of RA by integrating network pharmacology and pharmacokinetics. By constructing the visualization network of "pharmacodynamic ingredient-target-pathway", the potential Q-Marker of HQC treatment for RA was preliminatively predicted. A rat model of rheumatic heat obstruction syndrome collagene-induced arthritis (CIA) was established to elucidate the dynamic quantification law of pharmacodynamic components of HQC in the disease state of rats. To establish the inflammatory model of RA synovial fibroblasts (MH7A) induced by tumor necrosis factor-α (TNF-α) in vitro. The effects of active ingredients on protein expression of sphingosin kinase-1 (Sphk1) and p-SphK1 were detected. The network pharmacological results showed that baicalin, geniposide, luteolin, coixol and amygdalin were the important active components of HQC treatment for RA. Quantitative analysis results further verified the measurability of these five components. The expression of Sphk1 and p-SphK1 was significantly inhibited by geniposide and baicalin by Western blotting. The above studies determined that the above 5 components could be used as Q-markers in the treatment of RA by HQC. This experiment was approved by the Experimental Animal Ethics Committee of Anhui University of Chinese Medicine (approval number: AHUCM-rats-2021049). All procedures were conducted in strict accordance with the principles of animal use and care.

Screening of quantitative preparation quality markers of Zhibao Sanbian Wan / 药学学报

On the basis of the qualitative preparation quality markers of Zhibao Sanbian Wan (ZBSBW), we screened out the quantitative markers and evaluated the content consistency of ZBSBW. A method capable of simultaneously determining 34 compounds in ZBSBW was established based on HPLC-MS/MS, and 16 batches of ZBSBW were simultaneously analyzed by this method. Furthermore, we explored a general strategy for analyzing the component migration in preparation, plasma, brain tissue and cerebrospinal fluid. The methodological investigation was confirmed by linear range, recovery (85.10%-105.07%), precision (RSD: 1.37%-4.58%), stability, and repeatability (3.00%-12.45%), the established method was suitable for the detection and quantification of the compounds in ZBSBW. The contents of compounds in ZBSBW were all lower than 1 mg·g-1, and the contents and daily dose of nystose were the highest, followed by echinacoside, paeoniflorin, osthole and paeonol. The results of systematic clustering showed that the contents were consistent for ordinary preparations of ZBSBW. The principal component analysis showed that the components of berberine, ginsenoside Re, ginsenoside Rg1, pinoresinol diglucoside and tenuifolin had large variation, which contributed significantly to the grouping. The contents of echinacoside, verbascoside, polygalaxanthone Ⅲ, β-ecdysterone, osthole, alisol B 23-acetate, liquiritin and glycyrrhizic acid were stable from batch to batch. The animal experiment results showed that osthole, paeonol and liquiritin in ZBSBW could be absorbed into the blood and enter the brain tissue by passing through the blood-brain barrier. All animal studies were reviewed and approved by the Institutional Animal Care and Use Committee at Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences (No. 2020B071). The above compounds contributed the quantitative preparation quality markers of ZBSBW. In conclusion, the HPLC-MS/MS method established in this study was sensitive, accurate and rapid, and could be used for simultaneous quantification of 34 compounds and content consistency evaluation of multiple batches of preparations in ZBSBW. The result provided a methodological basis for the screening of quantitative preparation quality markers and material basis research of ZBSBW.

Research on Preparation Process and Quality Evaluation of Traditional Chinese Medicine Dispensing Granules and Its Consistency with Traditional Decoction： A Review / 中国实验方剂学杂志

Traditional Chinese medicine dispensing granules（TCMDGs）is the new type of decoction pieces with the development of modernization of TCM， which has received mixed opinions since its practical application. In 2021， the national departments issued Announcement on Ending the Pilot Work of TCMDGs， marking the end of the 28-year pilot work of TCMDGs， and eligible TCM enterprises can produce TCMDGs after filing. However， this does not mean that the preparation process， quality standard and efficacy research of TCMDGs have been developed and matured， on the contrary， there are still some problems that need to be solved and gradually improved. For example， in the production process， there are problems such as unclear， unified and non-standardized preparation parameters. In terms of quality control， there are some problems such as lack of producing area regulation， variety selection and processing specification. In terms of consistency evaluation with traditional decoction， there are problems such as unclear relationship between the chemical constituents and pharmacological effects of the two. Therefore， in view of some prominent problems of TCMDGs at present， this paper takes the published literature as the main data source and combines the specific requirements of the code or technical standards such as the 2020 edition of Chinese Pharmacopoeia， Publicity of the Unified Standard on the Varieties of TCMDGs， Quality Control and Standard Formulation Technical Requirements of TCMDGs. The production process of TCMDGs， the origin and variety of raw materials， the processing of decoction pieces， the quality control standard and the consistency evaluation of formula granules and traditional decoction were sorted out and visualized by literature mining， data analysis and list comparison. Based on the analysis results， the following suggestions were made. In terms of preparation process， the completeness and standardization of process parameters should be strengthened. In terms of quality evaluation， attention should be paid to the relationship between the authenticity， variety， processing and quality of medicinal materials. In the consistency evaluation of formula granules and traditional decoction， the deep difference and mechanism between TCMDGs and traditional decoction were discussed by combining structural Chinese medicine， quality marker（Q-Marker） theory and physicochemical characterization， so as to provide reference for the application and development of TCMDGs.

Discussion on Material Basis of Different Parts of Mulberry with Different Effects Based on Molecular Connectivity Index / 中国实验方剂学杂志

ObjectiveTo explore the material basis for the difference in the efficacy of different parts of mulberry based on molecular connectivity index （MCI）. MethodBy referring to the relevant literature at home and abroad and traditional Chinese medicine systems pharmacology database and analysis platform （TCMSP） database， the chemical composition database of mulberry-source medicinal materials was established. Venn analysis was carried out on the components among mulberry-source medicinal materials. The components in the database were divided into 10 categories， and the composition information was analyzed. According to MCI value， all components of mulberry-source medicinal materials were divided into different groups. The angle cosine method was used to calculate the MCI similarity. The average MCI values of the common component group from 0-8 orders and CI of mulberry-source medicinal materials were calculated. ResultThe components with high similarity such as （+）-cycloolivil， 1′-methoxy-2′-hydroxydihydromollugin， kuwanon， morusin and 1-deoxynojirimycin were selected as potential pharmacodynamic components. Mulberry-source medicinal materials could be divided into five component groups. The similarity between component groups and total components was 0.760-0.999， and the similarity between component groups was 0.248-0.999. In Mori Ramulus， Mori Folium， Mori Cortex and Mori Fructus， the average MCI values of their flavonoids from 0-8 orders were 4.57， 4.59， 6.41， 4.24， respectively. The average MCI values of alkaloids from 0-8 orders were 2.65， 4.55， 2.58， 2.78， respectively. The average CI values from 0-8 orders were 5.51， 5.49， 5.44 and 2.88， respectively. ConclusionIt is preliminarily concluded that there are differences in the flavonoids and pathways of hypoglycemic effects between Mori Cortex and the other three mulberry-source medicinal materials. The MCI values of alkaloids from 0-8 orders in Mori Folium and Mori Fructus were higher， but their inhibitory activity of α-glucosidase were lower than those of Mori Ramulus and Mori Cortex. The structural characteristics of the total components of Mori Fructus represented by CI were quite different from the other three mulberry-source medicinal materials.

Research progress and prospects for the use of plant metabolomics in quality evaluation of traditional Chinese medicinal materials / 药学学报

The quality of traditional Chinese medicine has a direct impact on the effectiveness and safety of its use, and is the premise necessary to ensure the healthy development of the traditional Chinese medicine industry. Comprehensive and accurate control and evaluation of the quality of medicinal materials is of great significance to the traditional Chinese medicine industry, but the complexity and dynamics of the chemical composition of medicinal materials makes their quality evaluation a challenge. Plant metabolomics provides an integrated and comprehensive analysis that is consistent with the holistic approach of traditional Chinese medicine. Chemical information therein promotes the establishment of a traceable system and provides new ideas and methods for the quality evaluation of medicinal materials. Plant metabolomics in the quality evaluation of medicinal materials is gradually increasing, and the core is the screening and identification of differential metabolites or specific marker compounds by means of stoichiometry. This study focused on the main factors that affect the quality of medicinal materials, such as origin, environmental adversity, varieties, harvest time, commercial specification and TCM processing. We describe the research progress in plant metabolomics combined with chemometrics analysis for the quality control and evaluation of medicinal materials, summarize existing problems, identify trends, and propose future research directions. Metabolomics plays an increasingly important role in the quality evaluation of medicinal materials, but the absolute qualitative and quantitative information of metabolomics needs to be further developed, and a single 'omics' technique is not sufficient for an in-depth analysis of medicinal value. In the future, standardization of plant metabolomics methods and a more complete database should be actively promoted, and plant metabolomics should be integrated into quality marker exploration. Plant metabolomics will need to be integrated with other 'omics' methods to improve the quality and evaluation system of medicinal materials.
