TCMSSD: A comprehensive database focused on syndrome standardization.

BACKGROUD: Quantitative and standardized research on syndrome differentiation has always been at the forefront of modernizing Traditional Chinese Medicine (TCM) theory. However, the majority of existing databases primarily concentrate on the network pharmacology of herbal prescriptions, and there are limited databases specifically dedicated to TCM syndrome differentiation. PURPOSE: In response to this gap, we have developed the Traditional Chinese Medical Syndrome Standardization Database (TCMSSD, http://tcmssd.ratcm.cn). METHODS: TCMSSD is a comprehensive database that gathers data from various sources, including TCM literature such as TCM Syndrome Studies (Zhong Yi Zheng Hou Xue) and TCM Internal Medicine (Zhong Yi Nei Ke Xue) and various public databases such as TCMID and ETCM. In our study, we employ a deep learning approach to construct the knowledge graph and utilize the BM25 algorithm for syndrome prediction. RESULTS: The TCMSSD integrates the essence of TCM with the modern medical system, providing a comprehensive collection of information related to TCM. It includes 624 syndromes, 133,518 prescriptions, 8,073 diseases (including 1,843 TCM-specific diseases), 8,259 Chinese herbal medicines, 43,413 ingredients, 17,602 targets, and 8,182 drugs. By analyzing input data and comparing it with the patterns and characteristics recorded in the database, the syndrome prediction tool generates predictions based on established correlations and patterns. CONCLUSION: The TCMSSD fills the gap in existing databases by providing a comprehensive resource for quantitative and standardized research on TCM syndrome differentiation and laid the foundation for research on the biological basis of syndromes.

[Problems and thoughts in clinical safety evaluation of traditional Chinese medicine].

Amid the modernization and internationalization of traditional Chinese medicine(TCM), the safety of TCM has attracted much attention. At the moment, the government, scientific research teams, and pharmaceutical enterprises have made great efforts to explore methods and techniques for clinical safety evaluation of TCM. Although considerable achievements have been made, there are still many problems, such as the non-standard terms of adverse reactions of TCM, unclear evaluation indicators, unreasonable judgment methods, lack of evaluation models, out-of-date evaluation standards, and unsound reporting systems. Therefore, it is urgent to further deepen the research mode and method of clinical safety evaluation of TCM. Based on the current national requirements for the life-cycle management of drugs, this study focused on the problems in the five dimensions of clinical safety evaluation of TCM, including normative terms, evaluation modes, judgment methods, evaluation standards, and reporting systems, and proposed suggestions on the development of a life-cycle clinical safety evaluation method that conformed to the characteristics of TCM, hoping to provide a reference for future research.

Shenlian (SL) Decoction, a Traditional Chinese Medicine Compound, May Ameliorate Blood Glucose via Mediating the Gut Microbiota in db/db Mice.

Shenlian (SL) decoction is a herbal formula composed of Coptis and ginseng, of which berberine and ginsenoside are the main constituents. Even though SL decoction is widely used in treating diabetes in China, the mechanism of its antidiabetes function still needs further study. Gut microbiota disorder is one of the important factors that cause diabetes. To explore the effect of SL decoction on intestinal microbiota, gut microbiota of mice was analyzed by sequencing the gut bacterial 16S rRNA V3+V4 region and metagenomics. In this study, results demonstrated that SL decoction had a better hypoglycemic effect and ß cell protection effect than either ginseng or Coptis chinensis. Alpha diversity analysis showed that all interventions with ginseng, Coptis, and SL decoction could reverse the increased diversity and richness of gut microbiota in db/db mice. PCoA analysis showed oral SL decoction significantly alters gut microbiota composition in db/db mice. 395 OTUs showed significant differences after SL treatment, of which 37 OTUs enriched by SL decoction showed a significant negative correlation with FBG, and 204 OTUs decreased by SL decoction showed a significant positive correlation with FBG. Results of KEGG analysis and metagenomic sequencing showed that SL decoction could reduce the Prevotellaceae, Rikenellaceae, and Helicobacteraceae, which were related to lipopolysaccharide biosynthesis, riboflavin metabolism, and peroxisome, respectively. It could also upregulate the abundance of Bacteroidaceae, which contributed to the metabolism of starch and sucrose as well as pentose-glucuronate interconversions. In the species level, SL decoction significantly upregulates the relative abundance of Bacteroides_acidifaciens which showed a significant negative correlation with FBG and was reported to be a potential agent for modulating metabolic disorders such as diabetes and obesity. In conclusion, SL decoction was effective in hypoglycemia and its mechanism may be related to regulating gut microbiota via upregulating Bacteroides_acidifaciens.

Quality markers of Baizhu dispensing granules based on multi-component qualitative and quantitative analysis combined with network pharmacology and chemometric analysis.

ETHNOPHARMACOLOGICAL RELEVANCE: The dispensing granules of traditional Chinese medicines (TCMs) is an innovative form of medicinal material for TCMs decoction, which is gradually recognized in the clinic due to being suitable for production on a large scale and convenient to take for patients. However, the quality control of TCMs dispensing granules is being challenged, because they contain too many unrevealed hydrophilic components. AIM OF THE STUDY: Here, the dispensing granules produced from the rhizome of Atractylodes macrocephala (Baizhu dispensing granules), were explored as a case to explore the quality markers correlated to the clinical efficacy of TCMs dispensing granules by a comprehensive strategy of integrating chemical profiling, network pharmacology, and chemometric analysis. MATERIALS AND METHODS: First, the chemical profiling of Baizhu dispensing granules was characterized by using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS). Subsequently, the potential active components responsible for the efficacy of Baizhu dispensing granules were screened via network pharmacology, and the ultra-performance liquid chromatography coupled with photodiode array detector (UPLC-PDA) method was developed for quantitative analysis of the potential active components in 26 batches of Baizhu dispensing granules. Finally, the quality markers of Baizhu dispensing granules were deciphered based on content variations of potential active components and chemometric analysis. RESULTS: A total of 69 components were identified from Baizhu dispensing granules. Network pharmacology analysis further revealed that eight of them including five caffeoylquinic acids (31, 32, 36, 42, 44) and three sesquiterpenoids (63, 67, 76) were intimately connected to the core targets of dyspepsia, enteritis, gastritis and immunity. The contents of eight components differed greatly among 26 batches of Baizhu dispensing granules. Chlorogenic acid (31), cryptochlorogenic acid (32) and atractylenolide III (63) have higher concentrations and make great contributions to distinguish different batches of the Baizhu dispensing granules based on principal component analysis (PCA) and orthogonal partial least squares-discriminate analysis (OPLS-DA), and could be used as the quality markers of Baizhu dispensing granules. CONCLUSIONS: Our study defined the quality markers of Baizhu dispensing granules, which will benefit further investigation on the quality evaluation of TCMs dispensing granules containing Baizhu. The strategy used in this study will be helpful for discovering the quality markers of other TCMs dispensing granules.

Biological composition analysis of a natural medicine, Faeces Vespertilionis, with complex sources using DNA metabarcoding.

Faeces Vespertilionis is a commonly used fecal traditional Chinese medicine. Traditionally, it is identified relying only on morphological characters. This poses a serious challenge to the composition analysis accuracy of this complex biological mixture. Thus, for quality control purposes, an accurate and effective method should be provided for taxonomic identification of Faeces Vespertilionis. In this study, 26 samples of Faeces Vespertilionis from ten provinces in China were tested using DNA metabarcoding. Seven operational taxonomic units (OTUs) were detected as belonging to bats. Among them, Hipposideros armiger (Hodgson, 1835) and Rhinolophus ferrumequinum (Schober and Grimmberger, 1997) were the main host sources of Faeces Vespertilionis samples, with average relative abundances of 59.3% and 24.1%, respectively. Biodiversity analysis showed that Diptera and Lepidoptera were the most frequently consumed insects. At the species level, 19 taxa were clearly identified. Overall, our study used DNA metabarcoding to analyze the biological composition of Faeces Vespertilionis, which provides a new idea for the quality control of this special traditional Chinese medicine.

Advanced applications of mass spectrometry imaging technology in quality control and safety assessments of traditional Chinese medicines.

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Chinese medicines (TCMs) have made great contributions to the prevention and treatment of human diseases in China, and especially in cases of COVID-19. However, due to quality problems, the lack of standards, and the diversity of dosage forms, adverse reactions to TCMs often occur. Moreover, the composition of TCMs makes them extremely challenging to extract and isolate, complicating studies of toxicity mechanisms. AIM OF THE REVIEW: The aim of this paper is therefore to summarize the advanced applications of mass spectrometry imaging (MSI) technology in the quality control, safety evaluations, and determination of toxicity mechanisms of TCMs. MATERIALS AND METHODS: Relevant studies from the literature have been collected from scientific databases, such as "PubMed", "Scifinder", "Elsevier", "Google Scholar" using the keywords "MSI", "traditional Chinese medicines", "quality control", "metabolomics", and "mechanism". RESULTS: MSI is a new analytical imaging technology that can detect and image the metabolic changes of multiple components of TCMs in plants and animals in a high throughput manner. Compared to other chemical analysis methods, such as liquid chromatography-mass spectrometry (LC-MS), this method does not require the complex extraction and separation of TCMs, and is fast, has high sensitivity, is label-free, and can be performed in high-throughput. Combined with chemometrics methods, MSI can be quickly and easily used for quality screening of TCMs. In addition, this technology can be used to further focus on potential biomarkers and explore the therapeutic/toxic mechanisms of TCMs. CONCLUSIONS: As a new type of analysis method, MSI has unique advantages to metabolic analysis, quality control, and mechanisms of action explorations of TCMs, and contributes to the establishment of quality standards to explore the safety and toxicology of TCMs.

The effectiveness and safety of Chuna manual therapy adjuvant to Western medicine in patients with chronic obstructive pulmonary disease: Study protocol for a randomized, single-blind, investigator-initiated, pilot trial.

BACKGROUND: In chronic obstructive pulmonary disease (COPD) management, greater emphasis has been placed on symptomatic improvement and enhanced quality of life in patients. Manual therapy among respiratory rehabilitation programs has received much attention recently, with the publication of numerous studies. In South Korea, a method known as Chuna Manual Therapy (CMT) has been applied in the management of COPD patients and in clinical practice, but the clinical basis for safety and effectiveness is yet to be established. Therefore, rigorously designed randomized controlled trials are required. We aimed to evaluate the feasibility of assessing the add-on effect and safety of CMT administered with standard Western medicine therapy for the treatment of COPD. METHODS: This is a randomized, single-blind, single-center clinical pilot trial. Patients with COPD receiving standard drug therapy are randomly divided into an experimental group (n = 20) and a control group (n = 20) at a 1:1 ratio. The experimental group receives CMT adding to the standard medical therapy once a week for 8 weeks. The control group receives only the standard drug treatment. The trial is conducted with an outcome assessor and statistician blinding. The primary outcome is the 6-minute walk test. The secondary outcomes include the pulmonary function test, the Modified Medical Research Council, visual analog scale for dyspnea, COPD assessment test, quality of life using the St. George's respiratory questionnaire, EuroQOL five dimensions questionnaire, and Korean pattern identification questionnaire. Adverse events are also be evaluated. CONCLUSIONS: The results of this study will provide the feasibility of a large-scale clinical trial to establish high-quality clinical evidence of CMT for COPD.

Comparative study on the antituberculous effect and mechanism of the traditional Chinese medicines NiuBeiXiaoHe extract and JieHeWan.

BACKGROUND: The traditional Chinese medicine NiuBeiXiaoHe (NBXH) extract and Chinese medicine preparation JieHeWan (JHW) exhibit anti-tuberculosis effects. The anti- tuberculosis effect of NBXH was compared with that of JHW to elucidate the mechanism of action of NBXH. METHODS: BALB/c mice aged 6-8 weeks were randomly divided into a normal control group, Tuberculosis (TB) model group, JHW treatment group, and NBXH treatment group. After 3 and 13 weeks of treatment, the therapeutic effect in each group was evaluated by comparing lung histopathology, lung and liver colony counts, the number of spots representing effector T cells secreting IFN-γ in an ELISPOT, and the levels of Th1, Th2, and Th17 cytokines, which were measured by a cytometric bead array (CBA). Mouse RNA samples were subjected to transcriptome sequencing. RESULTS: After 13 weeks of treatment, the mean histopathological lesion area of the NBXH group was significantly smaller than that of the TB model group (P < 0.05). Compared with those in the TB model group, the lung colony counts in the JHW and NBXH groups were significantly decreased (P < 0.05), and the IL-2 and IL-4 levels in the NBXH group were significantly increased (P < 0.05). NBXH partly restored significant changes in gene expression caused by Mycobacterium tuberculosis (M. tuberculosis) infection. According to GO and KEGG analyses, the changes in biological process (BP), cell composition (CC) and molecular function (MF) terms and in signaling pathways caused by NBXH and JHW treatment were not completely consistent, but they were mainly related to the immune response and inflammatory response in the mouse TB model. CONCLUSIONS: NBXH had therapeutic effects similar to those of JHW in improving lung histopathology, reducing lung colony counts, and regulating the levels of cytokines. NBXH restored significant changes in gene expression and repaired cell damage caused by M. tuberculosis infection by regulating immune-related pathways, which clarified the mechanism of action of NBXH.

An integrated approach to discriminate the quality markers of Traditional Chinese medicine preparation based on multi-dimensional characteristic network: Shenqi Jiangtang Granule as a case.

BACKGROUND: Due to the complexity of traditional Chinese medicine (TCM), the current quality evaluation of TCM are difficult to associate with clinical efficacy. Shenqi Jiangtang Granule (SJG), a classical TCM formula, is proven as a therapy for treatment of type II diabetes mellitus (DM) and complications while the substantial basis of the therapeutic effects is not clear. PURPOSE: The present study proposed an integrated approach to discriminate the quality markers (Q-markers) based on multi-dimensional characteristic network for quality control of TCM. METHODS: The multi-dimensional characteristic network was established by "Spider-web" mode, which was comprehensively integrating "compatibility-content-activity- efficiency-stability" of the candidate ingredients. The activity dimension was evaluated by the inhibitory activity of SJG on α-glucosidase and aldose reductase. The efficacy dimension was assessed through the association between the compounds and the target pathway of diabetic nephropathy (DN) based on integrated pharmacology platform. Each dimension for the feature network was quantified by multivariate statistical analysis, and regression area of the candidate compounds was constructed in the network. Finally, the candidate compounds were sorted comprehensively by the regression area. RESULTS: A total of 30 chemical compounds with effective hypoglycemic activity were identified as the potential Q-markers. From the data analysis, three dimensions of activity, efficacy and content performed a greater impact on the regression area of the characteristic network. Among these compounds, ginsenoside Re, ginsenoside Rd, ginsenoside Rg1, calycosin, ginsenoside Rb1, formononetin, astragaloside IV, ginsenoside Rf, ginsenoside Rc, notoginsenoside Fe, schisandrol A, gomisin D were screened out as the candidate Q-markers of SJG. CONCLUSION: The multi-dimensional characteristic network integrating compatibility, content, activity, efficiency and stability is efficient to discriminate the potential Q-markers of TCM prescription. Our results demonstrated that 12 candidate compounds from Panax Ginseng, Radix Astragali and Schisandrae Chinensis might select as Q-markers for qualitative evaluation of SJG.

Tuina for diabetic peripheral neuropathy: A protocol for a systematic review and meta-analysis.

With the change in modern dietary structure, the incidence of diabetes is increasing year by year, and DPN is also on the rise. Tuina therapy has been widely used in the treatment of DPN, but there is no systematic review on the treatment of DPN. Therefore, this study aimed to conduct a meta-analysis of Tuina in the treatment of DPN to clarify its efficacy. METHODS: The following electronic databases will be searched: PubMed, the Cochrane Library, Embase, Web of Science, Medline, CNKI, Chinese Biomedical Literature Database, VIP, and Wan Fang databases. We will consider articles published between database initiation and May 2021. We will use Review Manager 5.4, provided by the Cochrane Collaborative Network for statistical analysis. Clinical randomized controlled trials related to Tuina for diabetic peripheral neuropathy were included in this study. Language is limited to both Chinese and English. Research selection, data extraction, and research quality assessments were independently completed by two researchers. We then assessed the quality and risk of the included studies and observed the outcome measures. RESULTS: This study provides a high-quality synthesis to assess the effectiveness and safety of Tuina for treating diabetic peripheral neuropathy. CONCLUSION: This systematic review will provide evidence to determine whether Tuina is an effective and safe intervention for patients with diabetic peripheral neuropathy. ETHICS AND DISSEMINATION: The protocol of the systematic review does not require ethical approval because it does not involve humans. This article will be published in peer-reviewed journals and presented at relevant conferences. REGISTRATION NUMBER: INPLASY202150027.

RIGHT for acupuncture: An extension of the RIGHT statement for clinical practice guidelines on acupuncture.

OBJECTIVE: In 2017, the International Standard for Reporting Items for practice Guideline in HealThcare (RIGHT) published reporting guidelines to enhance transparency and clarity in the process of developing clinical practice guidelines (CPGs). Given the original tool was developed in 2017 and demanded in developing and reporting high quality of acupuncture CPGs, an extension with a focus on a specific reporting checklist was warranted. STUDY DESIGN AND SETTING: The study was designed based on the methodology recommended by the Enhancing the Quality and Transparency Of Health Research (EQUATOR) Network with modification accordingly. A reporting checklist and its elaboration and explanations for users were developed. RESULTS: A checklist of seven sections (Basic information, Background, Evidence, Recommendations, Funding, Declaration and management of interest, Other information), twenty-three first level items and forty-three second level items was developed. We clarified the rationales of the items and provided explanations and examples of each item for additional guidance. CONCLUSION: The RIGHT for Acupuncture checklist identifies a set of items to be reported when reviewing clinical practice guidelines on acupuncture. This extension can be expected to improve the reporting quality of CPGs on acupuncture.

Discovery of potential Q-marker of traditional Chinese medicine based on plant metabolomics and network pharmacology: Periplocae Cortex as an example.

BACKGROUND: Quality control exerted great importance on the clinical application of drugs for ensuring effectiveness and safety. Due to chemical complexity, diversity among different producing areas and harvest seasons, as well as unintentionally mixed with non-medicinal parts, the current quality standards of traditional Chinese medicine (TCM) still faced challenges in evaluating the overall chemical consistency. PURPOSE: We aimed to develop a new strategy to discover potential quality marker (Q-marker) of TCM by integrating plant metabolomics and network pharmacology, using Periplocae Cortex (GP, the dried root bark of Periploca sepium Bge.) as an example. METHODS: First, plant metabolomics analysis was performed by UPLC/Q-TOF MS in 89 batches of samples to discover chemical markers to distinguish medicinal parts (GP) and non-medicinal parts (the dried stem bark of Periploca sepium Bge. (JP)), harvest seasons and producing region of Periplocae Cortex. Second, network pharmacology was applied to explore the initial linkages among chemical constituents, targets and diseases. Last, potential Q-marker were selected by integrating analysis of plant metabolomics and network pharmacology, and the quantification method of Q-marker was developed by using UPLC-TQ-MS. RESULTS: The chemical profiling of GP and JP was investigated. Fifteen distinguishing features were designated as core chemical markers to distinguish GP and JP. Besides, the content of 4-methoxybenzaldehyde-2-O-ß-d-xylopyranosyl-(1→6)-ß-d-glucopyranoside could be used to identify Periplocae Cortex harvested in spring-autumn or summer. Meanwhile, a total of 15 components targeted rheumatoid arthritis were screened out based on network pharmacology. Taking absorbed constituents into consideration, 23 constituents were selected as potential Q-marker. A simultaneous quantification method (together with 11 semi-quantitative analysis) was developed and applied to the analysis of 20 batches of commercial Periplocae Cortex on the market. The PLS-DA model was successfully developed to distinguish GP and JP samples. In addition, the artificially mixed GP sample, which contained no less than 10% of the adulterant (JP), could also be correctly identified. CONCLUSION: Our results indicated that 9 ingredients could be considered as Q-marker of Periplocae Cortex. This study has also demonstrated that the plant metabolomics and network pharmacology could be used as an effective approach for discovering Q-marker of TCM to fulfill the evaluation of overall chemical consistency among samples from different producing areas, harvest seasons, and even those commercial crude drugs, which might be mixed with a small amount of non-medicinal parts.
