[Methodological and reporting quality of randomized controlled trials on the treatment of benign prostatic hyperplasia with traditional Chinese medicine].

OBJECTIVE: To systematically evaluate the methodological quality and reporting quality of randomized controlled trials (RCT) on the treatment of BPH with traditional Chinese medicine (TCM), in order to provide some methodological reference for clinical practice and research. METHODS: We searched CNKI, VIP, Wanfang Data and PubMed for RCTs on the treatment of BPH with TCM published in China from January 2013 to November 2023. Two researchers screened the literature separately, and evaluated the methodological and reporting quality of the RCTs based on the Cochrane bias risk assessment tool and CONSORT TCM compound. RESULTS: Totally, 88 RCTs were included in this study. In terms of methodological quality, according to the Cochrane bias risk assessment tool, 27 biases in the process of randomization were identified as of low-risk and the other 61 of a certain risk. Among the allocation-related biases deviating from the established interventions, 76 were of low risk, 10 of a certain risk and 2 of high risk; among the compliance-related biases deviating from the established interventions, 76 were of low risk and 12 of a certain risk; among the biases due to missing outcome data, 86 were of low risk and 2 of a certain risk, while all the biases due to outcome measurement were of low risk; and among the biases from selective reporting, 65 were of low-risk, 2 of a certain risk and 21 of high-risk. In terms of reporting quality, according to the evaluation criteria of consort TCM compound, appropriate key words were used in 1 RCT (0.01%), the random assignment sequence method described in 27 (30.68%), the details of assignment limitation given in 5 (5.68%), assignment concealment mentioned in 3 (3.41%), the blind method and assignment concealment employed in 3 (3.41%), fall-offs recorded in 10 (11.36%), adverse events reported in 38 (43.18%), and limitations of the trials analyzed in 18 (20.45%). All the RCTs lacked complete intervention measures, subject flow chart, clinical trial registration and research schemes. CONCLUSION: At present, the methodological quality and reporting quality of RCTs on the treatment of BPH with TCM are generally low, with the main problems of incomplete experimental designs, lack of detailed description of randomized and blind methods, and insufficient TCM symptom evaluation of outcome indicators. Researchers should be cautious in adopting and applying the results reported, follow the CONSORT statement in design, registration, implement and reporting of the scheme, fully consider the clinical characteristics of TCM in the treatment of BPH, and reasonably design and report the evaluation indicators.

[Establishment and content validity assessment of evaluation index system for development value of traditional Chinese medicine preparations in medical institutions].

The development of traditional Chinese medicine(TCM) preparations as an incubator for new drugs in medical institutions has flourished, while an evaluation index system remains to be established for comprehensively assessing the development value of these prescriptions. This study established an item pool through literature research, employed the Delphi method to determine the content of evaluation indexes, and adopted the superiority chart to determine the weight of each index. Two-level evaluation index system for the development value of TCM preparations in medical institutions was established, which included 7 first-level items and 36 se-cond-level items, demonstrating scientific validity. The first-level items(weight) were inheritance(10.61%), effectiveness(23.22%), safety(22.71%), innovation(13.21%), economy(10.00%), suitability(8.57%), and accessibility(11.68%). The top three second-level items in terms of weight distribution were adverse reaction monitoring(6.73%), evidence of therapeutic effect(5.71%), and clinical response rate(4.75%). The bottom three second-level items were production advantages(0.86%), medicinal dosage(0.48%), and medicinal smell or taste(0.18%). The content validity of the established system was assessed, which revealed that the index system was reliable, with the overall and average content validity indexes of 0.47 and 0.90, respectively. Furthermore, the established evaluation index system was used to evaluate six TCM preparations in a city-level hospital of TCM in Sichuan Province, which demonstrated that the system had operability. The results indicate that the evaluation index system is scientific, reliable, and operable, providing a reference for developers to selectively develop TCM preparations in medical institutions. In practical application, the system can be adjusted regarding the index weights according to actual conditions.

Optimization of the extraction process for Shenshou Taiyi powder based on Box-Behnken experimental design, standard relation, and FAHP-CRITIC methods.

BACKGROUND: Ancient classic prescription play a crucial role in the preservation and advancement of traditional Chinese medicine (TCM) theories. They represent a significant milestone in the ongoing development and transmission of TCM knowledge and practices and are considered one of the breakthroughs in the development of TCM inheritance. In the process of developing ancient classic prescriptions, many problems may still arise in ensuring quality consistency between traditional methods and modern production processes, among which the extraction process poses major challenges. This paper introduces a practical approach extracting an ancient classic prescription using a modern extraction process. The technique is demonstrated through the study of the extraction process of Shenshou Taiyi powder (STP). METHODS: This study focuses on optimising the STP extraction process to ensure consistency in the quality of the product obtained through ancient and modern processes using the standard relation and fuzzy analytic hierarchical process (FAHP) and criteria importance through intercriteria correlation (CRITIC) method integrated weights combined with the Box-Behnken response surface test. Using the contents of rosmarinic acid, isoimperatorin, puerarin, as well as the extract yield and fingerprint similarity as evaluation indexes of STP, the Box-Behnken response surface method was employed to examine the varying extraction parameters, including water addition ratio, extraction duration, and number of extractions. The weighted coefficients for each parameter were calculated by combining the benchmark correlation and FAHP-CRITIC method, deriving a comprehensive score. RESULTS: The optimal extraction process for STP consisted of a two extractions, each using at a tenfold quantity of water, performed for one hour. Process verification across three separate batches yielded a comprehensive score of 94.7, with a relative standard deviation of 0.76%. CONCLUSIONS: The application of the Box-Behnken response surface method combined with standard relation and FAHP-CRITIC approach proved to be stable and feasible for optimising the extraction process of STP.

An integrated strategy for quality control of Pseudobulbus Cremastrae seu Pleiones based on Q-marker.

Pseudobulbus Cremastrae seu Pleiones (PCsP), a traditional Chinese medicine known as ‶Shan-Ci-Gu″, possesses properties for clearing heat, counteracting toxicity, dissipating phlegm, and resolving masses. As a TCM with multiple bases, the dried pseudobulbs of Pleione bulbocodioides (PB), Pleione yunnanensis (PY) and Cremastra appendiculata (CA) are considered to be the official sources of PCsP. Additionally, several unofficial substitutes are also available in the market. To enhance the quality control of PCsP, an integrated strategy based on Q-marker was proposed. Initially, a study of integrating plant metabolomics, target isolation, structure identification, and activity testing afforded five Q-markers, including three new compounds. Furthermore, a quality evaluation method using a single standard to determine multi-components (SSDMC) based on Q-marker was established, which could effectively distinguish PB from CA and the counterfeit herbs. Finally, the transitivity of Q-markers was explored through a representative Chinese compound prescription containing PCsP. The results indicated that the identified Q-markers together with the established analysis methods could be effectively applied for quality control of PCsP and its preparations.

Molecular authentication of commercial "Qian-hu" through the integration of nrDNA internal transcribed spacer 2 and nucleotide signature.

BACKGROUND: Peucedani Radix, also known as "Qian-hu" is a traditional Chinese medicine derived from Peucedanum praeruptorum Dunn. It is widely utilized for treating wind-heat colds and coughs accompanied by excessive phlegm. However, due to morphological similarities, limited resources, and heightened market demand, numerous substitutes and adulterants of Peucedani Radix have emerged within the herbal medicine market. Moreover, Peucedani Radix is typically dried and sliced for sale, rendering traditional identification methods challenging. MATERIALS AND METHODS: We initially examined and compared 104 commercial "Qian-hu" samples from various Chinese medicinal markets and 44 species representing genuine, adulterants or substitutes, utilizing the mini barcode ITS2 region to elucidate the botanical origins of the commercial "Qian-hu". The nucleotide signature specific to Peucedani Radix was subsequently developed by analyzing the polymorphic sites within the aligned ITS2 sequences. RESULTS: The results demonstrated a success rate of 100% and 93.3% for DNA extraction and PCR amplification, respectively. Forty-five samples were authentic "Qian-hu", while the remaining samples were all adulterants, originating from nine distinct species. Peucedani Radix, its substitutes, and adulterants were successfully identified based on the neighbor-joining tree. The 24-bp nucleotide signature (5'-ATTGTCGTACGAATCCTCGTCGTC-3') revealed distinct differences between Peucedani Radix and its common substitutes and adulterants. The newly designed specific primers (PR-F/PR-R) can amplify the nucleotide signature region from commercial samples and processed materials with severe DNA degradation. CONCLUSIONS: We advocate for the utilization of ITS2 and nucleotide signature for the rapid and precise identification of herbal medicines and their adulterants to regulate the Chinese herbal medicine industry.

Intelligent quality control of traditional chinese medical tongue diagnosis images based on deep learning.

BACKGROUND: Computer-aided tongue and face diagnosis technology can make Traditional Chinese Medicine (TCM) more standardized, objective and quantified. However, many tongue images collected by the instrument may not meet the standard in clinical applications, which affects the subsequent quantitative analysis. The common tongue diagnosis instrument cannot determine whether the patient has fully extended the tongue or collected the face. OBJECTIVE: This paper proposes an image quality control algorithm based on deep learning to verify the eligibility of TCM tongue diagnosis images. METHODS: We firstly gathered enough images and categorized them into five states. Secondly, we preprocessed the training images. Thirdly, we built a ResNet34 model and trained it by the transfer learning method. Finally, we input the test images into the trained model and automatically filter out unqualified images and point out the reasons. RESULTS: Experimental results show that the model's quality control accuracy rate of the test dataset is as high as 97.06%. Our methods have the strong discriminative power of the learned representation. Compared with previous studies, it can guarantee subsequent tongue image processing. CONCLUSIONS: Our methods can guarantee the subsequent quantitative analysis of tongue shape, tongue state, tongue spirit, and facial complexion.

[Application of process analysis technology in traditional Chinese medicine manufacturing industry].

In the traditional Chinese medicine(TCM) manufacturing industry, quality control determines the safety, effectiveness, and quality stability of the final product. The traditional quality control method generally carries out sampling off-line testing of drugs after the end of the batch production, which is incomprehensive, and it fails to find the problems in the production process in time. Process analysis technology(PAT) uses process testing, mathematical modeling, data analysis, and other technologies to collect, analyze, feedback, control, and continuously improve the critical quality attributes(CQA) in all aspects of the production of TCM preparations in real time. The application of PAT in the TCM manufacturing industry is one of the research hotspots in recent years, which has the advantages of real-time, systematic, non-destructive, green, and rapid detection for the production quality control of TCM preparations. It can effectively ensure the stability of the quality of TCM preparations, improve production efficiency, and play a key role in the study of the quantity and quality transfer law of TCM. Commonly used PAT includes near-infrared spectroscopy, Raman spectroscopy, online microwave, etc. In addition, the establishment of an online detection model by PAT is the key basic work to realize intelligent manufacturing in TCM production. Obtaining real-time online detection data through PAT and establishing a closed-loop control model on this basis are a key common technical difficulty in the industry. This paper adopted systematic literature analysis to summarize the relevant Chinese and foreign literature, policies and regulations, and production applications, and it introduced the development trend and practical application of PAT, so as to provide references for accelerating the application of PAT in the TCM manufacturing industry, the intelligent transformation and upgrading, and high-quality development of the TCM industry.

Through literature pre-search, expert interviews, clinical research, and conference consensus, 16 clinical problems are identified in this guideline. PICO principles are used for evidence retrieval, screening, and synthesis. The evidence quality is evaluated for the included evidence bodies. Recommendation opinions and consensus suggestions are formed through three rounds of the Delphi expert questionnaire survey. An expert meeting is held to finalize the draft. The opinions of experts in traditional Chinese medicine, western medicine, integrated traditional Chinese and western medicine, methodology and pharmacy are widely solicited. The guideline contains five parts: scope, term and definition, diagnosis, treatment, and diagnosis and treatment flow chart of integrated traditional Chinese and western medicine. There are corresponding recommendations and summaries of evidence for clinical problems related to the diagnosis and treatment of integrated traditional Chinese and western medicine. This guideline is guided by clinical problems, combining disease differentiation and syndrome differentiation and integrating pre-pregnancy regulation and treatment and post-pregnancy preservation, highlighting the therapeutic advantages of integrated traditional Chinese and western medicine, so as to further standardize the clinical diagnosis and treatment of recurrent spontaneous abortion and promote the diagnosis and treatment level of integrated traditional Chinese and western medicine for recurrent spontaneous abortion.

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.

Perspectives and Practice in Eastern and Western Medicine for Pain Management in Rehabilitation Training after Orthopedic Trauma Surgery: A Qualitative Study.

BACKGROUND: Despite the increasing emphasis on rehabilitation training after orthopedic surgery, little is known about the pain caused by the procedure itself. Clinical practice is driven by beliefs in pain management. AIMS: This study aimed to explore the perspective of pain management during rehabilitation training after orthopedic trauma in China and its influencing factors from different perspectives in traditional Chinese medicine and Western medicine, respectively. DESIGN: A phenomenological qualitative study involving semi-structured interviews. SETTINGS:   METHODS: A qualitative study was conducted with 16 medical workers working in the Rehabilitation Medicine Department in eastern China from July 2022-February 2023. A directed method to thematic analysis was used to code the transcribed data and identify themes. RESULTS: Four main themes emerged. (1) Inconsistent perspectives and practice: Chinese doctors majoring in Western medicine felt sympathy, helpless, and had a lack of knowledge and misconception about pain. Traditional Chinese medicine deemed that pain is a protective mechanism and attached importance to holism and unique means. (2) Consistent outcome: Insufficient pain management will have a series of negative consequences for patients' recovery, forming a vicious cycle. (3) Expectations: Though they are not optimistic about traditional analgesics, enhancement, cooperation and ideal analgesic methods still be expressed, and (4) Concept transformation: Conducting nitrous oxide is a process not only to promote analgesic technology but also to promote the awareness and concept of pain management. CONCLUSIONS: Our study emphasized that medical workers should be aware of the importance of pain management at the same time while treating the disability. The study provides insight into pain management experiences within different educational backgrounds. The findings enable professionals to recognize the importance of pain management and its influencing factors to provide feasible and effective pain management strategies.

Osteoporosis guidelines on TCM drug therapies: a systematic quality evaluation and content analysis.

Objective: The aims of this study were to evaluate the quality of osteoporosis guidelines on traditional Chinese medicine (TCM) drug therapies and to analyze the specific recommendations of these guidelines. Methods: We systematically collected guidelines, evaluated the quality of the guidelines using the Appraisal of Guidelines Research and Evaluation (AGREE) II tool, and summarized the recommendations of TCM drug therapies using the Patient-Intervention-Comparator-Outcome (PICO) model as the analysis framework. Results and conclusions: A total of 20 guidelines were included. Overall quality evaluation results revealed that four guidelines were at level A, four at level B, and 12 at level C, whose quality needed to be improved in the domains of "stakeholder involvement", "rigor of development", "applicability" and "editorial independence". Stratified analysis suggested that the post-2020 guidelines were significantly better than those published before 2020 in the domains of "scope and purpose", "stakeholder involvement" and "editorial independence". Guidelines with evidence systems were significantly better than those without evidence systems in terms of "stakeholder involvement", "rigor of development", "clarity of presentation" and "applicability". The guidelines recommended TCM drug therapies for patients with osteopenia, osteoporosis and osteoporotic fracture. Recommended TCM drugs were mainly Chinese patent medicine alone or combined with Western medicine, with the outcome mainly focused on improving bone mineral density (BMD).

Viewpoint regarding "concise" of "classical formula" from case / 中国中药杂志

"Classical formula" are praised for their exact clinical efficacy,but many scholars of " classical formula" still remain in the simple symptoms and the superficial form of formula matching,failing to explore the connotation of " classical formula" in a subtle and in-depth way. The clinical curative effect and charm of " classical formula" mainly lie in " concise". " Concise" can be divided into many aspects,including " correspondence of formula and syndrome" infers pointing accuracy, " Classic formula" infers structure refining,and " pattern differentiation" infers process elaborating,ect. " Correspondence of formula and syndrome" requires doctors to take into account multiple factors such as physical characteristics,symptom features,diet taste and emotional preference of patients,so as to grasp its essence more accurately. " Classic formula" implies paying special attention to its composition and various methods of addition and subtraction. Not following Zhang Zhongjing's method and gilding the lily will affect the clinical efficacy. " Pattern differentiation" indicates doctors should separate Yin and Yang,examine syndrome features and distinguish the categories following the method of traditional Chinese medicine with comprehensive observation and comprehensive consideration in-depth so as to accurately select the appropriate prescription and improve the clinical efficacy.

Suplementos alimentares à base de plantas chinesas no mercado português / Chinese herbal food supplements in the portuguese market

Os fabricantes de suplementos alimentares recorren a plantas medicinais para a obtençao de beneficios na saúde. No entanto, algunas lacunas no sistema de monitorizaçao e fiscalizacao e, eventualmente, na legislaçao europeia em vigor, acabam por tornar possível a existencia de suplementos alimentares no mercado que nao apresentam valores nutricionais, nao tem rotulagem completamente esclarecedora ou, podem, inclusivamente, conter plantas/moléculas potencialemtne perigosas para a saude. Neste trabalho, estuda-se uma amostra de 71 suplementos recolhidos aleatoriamente no mercado em Lisboa e analisa-se a informaçao constate da sua rotulagem, procurando responde a um conjunto de questoes com impacto potencial na saude dos consumidores. Da amostra 50,7por ciento (36/71) tem nomes chineses da Medicina Tradicional Chinesa (MTC) e 49,3por ciento (35/71) tem denominaçao occidental. A percentagem de suplementos tendo entre 0 e 4 plantas ou partes de plantas como ingredientes é de 9,9 por ciento entre 5 e 9 é de 35,2por ciento, entre parte de planta mais frequente (ca.64por ciento) nos MTC é raíz de Glycyrrhiza uralensis, que pode tener efeitos sinérgicos com corticosteróides e digoxina, e pode causar hipertensao, edema, transtornos cardíacos, e potenciar o efeito de tiazidas e diuréticos. O ingrediente de frequencia maior (43-46por ciento) común a todos os suplementos é a raíz de Angelica sinensis, que pode provocar hemorragias se tomado com inibidores da agregaçao plaquetária (AU)

Manufactures of food supplements rely on medicinalplants to achieve health benefits. However, some gaps in the system of monitoring and enforcement, nd eventually in the current European legislation, end up making possible the existence of dietary supplements on the market that have no nutritional value, do not have quite enlightening information on labeling, and they may even contain plants or molecules potentially hazardous to health. In this paper, we study a sample of 71 randomly collected supplements in Lisbon area market and analyze the information contained in its labeling, trying to answer a set of questions with potential impact on consumer health. Of the sample, 50,7por ciento (36/71) have Chinese names (TCM)and 49,3 por ciento (35/71) have western names. The percentages of supplements having between 0 and 4 plants or parts of plants as ingredients is 9,9 por ciento, between 5 and 9 is 35,2por ciento, between 10 and 14 is 32,4 por ciento and 22,5 por ciento have 15 or more ingredients. The plant/plant part more frequent (ca. 64 por ciento) in TCM is the root of Glycyrrhia uralensis, which may have synergistic effects with digoxin and corticosteroids, and can cause hypertension, edema, cardiac disorders, and potentiate the effect of diuretics and thiazides. The higher frequency ingredient (43%-46 por ciento) common to all supplements is the root of Angelica sinensis, which may cause bleeding if taken with platelet aggregation inhibitors (AU)
