Mechanism of Xuanfei Baidu Tang in treatment of COVID-19 based on network pharmacology / 中国中药杂志

The study aimed to investigate the multi-constituent, multi-target mechanism of Xuanfei Baidu Tang(XFBD) in the treatment of coronavirus disease 2019(COVID-19), through exploring the main ingredients and effective targets of XFBD, as well as analyzing the correlation between XFBD targets and COVID-19. The compounds of each herb in XFBD were collected from TCM-PTD, ETCM, TCMSP and SymMap database. Next, the information of meridian tropisms was collected from Chinese Pharmacopoeia(2015 edition), and the target information of the major constituents of XFBD were obtained from TCM-PTD, ETCM, TCMSP and TargetNet database. Subsequently, the target network model and the major modules were generated by Cytoscape, and the functional enrichment analysis of XFBD targets were completed by DAVID and STRING. As a result, ten of the 13 herbs in XFBD belonged to the lung meridian, and 326 of the 1 224 putative XFBD targets were associated with the disease target of COVID-19, among which 109 targets were enriched in the disease pathways of viral infection and lung injury. The main biological pathways regulated by the key XFBD targets included viral infection, energy metabolism, immunity and inflammation, parasites and bacterial infections. In conclusion, the therapeutic mechanism of XFBD in COVID-19 showed a multi-herb, multi-constituent, multi-target pattern, with lung as the chief targeted organ. By regulating a series of biological pathways closely related to the occurrence and development of diseases, XFBD plays a role in balancing immunity, eliminating inflammation, regulating hepatic and biliary metabolism and recovering energy metabolism balance.

The bitter taste is one of the important properties among five flavors of Chinese materia medica (CMM), characterized by downbearing and discharging, drying dampness, and consolidating Yin. In common CMM, bitter-taste CMM accounts for a large proportion, indicating the importance of it. Through the efficacy of clearing away heat and dampness, reducing fire and removing toxin, bitter-taste CMM has achieved good results in treating diabetes in clinical application, proving their definite therapeutic effect on regulating glucose and lipid metabolism (main features of diabetes). At present, there are many reports about the chemical constituents and pharmacological effects of CMM on diabetes, but there are few reviews on the chemistry and biology of bitter-taste CMM. This study summarized the properties and compatibility characteristics of bitter-taste CMM for treating diabetes, and mainly analyzed the chemistry and biology basis of bitter-taste CMM with function of regulating glycolipid metabolism, laying foundation for further researches on properties theory of CMM.

Evidence-based Chinese medicine：theory and practice / 中国中药杂志

The introduction and popularization of evidence-based medicine has opened up a new research field of clinical efficacy evaluation of traditional Chinese medicine(TCM), produced new research ideas and methods, and promoted the progress of clinical research of TCM. After about 20 years assiduous study and earnest practice, the evidence based evaluation method and technique, which conforms to the characteristics of TCM theory and practice, has been developing continuously. Evidence-based Chinese medicine (EBCM) has gradually formed and become an important branch of evidence-based medicine. The basic concept of evidence-based Chinese medicine: EBCM is an applied discipline, following the theory and methodology of evidence-based medicine, to collect, evaluate, produce, transform the evidence of effectiveness, safety and economy of TCM, to reveal the feature and regular pattern of TCM taking effect, and to guide the development of clinical guidelines, clinical pathways and health decisions. The effects and achievements of EBCM development: secondary studies mainly based on systematic review/Meta-analysis were extensively carried out; clinical efficacy studies mainly relying on randomized controlled trials grew rapidly; clinical safety evaluations based on real world study have been conducted; methodological researches mainly focused on study quality control deepened gradually; internationalization researches mainly on report specifications have got some breakthroughs; standardization researches based on treatment specification were strengthened gradually; the research team and talents with the characteristics of inter-disciplinary have been steadily increased. A number of high-quality research findings have been published at international well-known journals; the clinical efficacy and safety evidence of TCM has been increased; the level of clinical rational use of TCM has been improved; a large number of Chinese patent medicines with big market have been cultured. The future missions of EBCM mainly consist of four categories (scientific research, methodology and standard, platform construction and personnel training) with nine tasks. ①Carry out systematic reviews to systematically collect clinical trial reports of TCM and establish database of clinical evidence of TCM; ②Carry out evidence transformation research to lay the foundation for the development of clinical diagnosis and treatment guidelines, clinical pathways of TCM, and for the screening of basic drug list and medical insurance list, and for the policy-making relevant to TCM; ③Conduct researches to evaluate the advantages and effective regular patterns of TCM and form the evidence chain of TCM efficacy; ④Carry out researches for the safety evaluation of TCM, and provide evidence supporting the rational and safe use of TCM in clinical practice; ⑤Conduct researches on methodology of EBCM and provide method for developing high quality evidence; ⑥Carry out researches to develop standards and norms of TCM, and to form methods, standards, specifications and technical systems; ⑦Establish data management platform for evidence-based evaluation of TCM, and promote data sharing; ⑧Build international academic exchange platform to promote international cooperation and mutual recognition of EBCM research; ⑨Carry out education and popularization activities of evidence-based evaluation methods, and train undergraduate students, graduate students, clinical healthcare providers and practitioners of TCM. The development of EBCM, as it was, not only promoted the transformation of clinical research and decision-making mode of TCM, contributed to the modernization and internationalization of TCM, but also enriched the connotation of Evidence-based Medicine.

A strategy of constructing the technological system for quality control of Chinese medicine based on process control and management / 中国中药杂志

The current situation, bottleneck problems and severe challenges in quality control technology of Chinese Medicine (CM) are briefly described. It is presented to change the phenomenon related to the post-test as the main means and contempt for process control in drug regulation, reverse the situation of neglecting the development of process control and management technology for pharmaceutical manufacture and reconstruct the technological system for quality control of CM products. The regulation and technology system based on process control and management for controlling CM quality should be established to solve weighty realistic problems of CM industry from the root causes, including backwardness of quality control technology, weakness of quality risk control measures, poor reputation of product quality and so on. By this way, the obstacles from poor controllability of CM product quality could be broken. Concentrating on those difficult problems and weak links in the technical field of CM quality control, it is proposed to build CMC (Chemistry, Manufacturing and Controls) regulation for CM products with Chinese characteristics and promote the regulation international recognition as soon as possible. The CMC technical framework, which is clinical efficacy-oriented, manufacturing manner-centered and process control-focused, was designed. To address the clinical characteristics of traditional Chinese medicine (TCM) and the production feature of CM manufacture, it is suggested to establish quality control engineering for CM manufacturing by integrating pharmaceutical analysis, TCM chemistry, TCM pharmacology, pharmaceutical engineering, control engineering, management engineering and other disciplines. Further, a theoretical model of quality control engineering for CM manufacturing and the methodology of digital pharmaceutical engineering are proposed. A technology pathway for promoting CM standard and realizing the strategic goal of CM internationalization is elaborated.

Expert consensus on the design and implementation of clinical safety centralized monitoring study of Chinese medical injection / 中国中药杂志

Along with the increase of clinical application, the safety of traditional Chinese medicine gained more and more attentions. In particular, the safety evaluation of Chinese medical injections has become a mandatory task should be completed by pharmaceutical companies under the supervision of China Food and Drug Administration(CFDA). Due to the weak foundation of previous studies, the safety issues of Chinese medical injections have not been fully understood, and lack of scientific and rational risk management programs. Clinical safety centralized monitoring(CSCM) is an important method for post-market safety evaluation of Chinese medicine. Due to the lack of appropriate norms and procedures, the quality of similar research is uneven, and the results vary. Combined with practical experience with experts' suggestions, we developed this expert consensus on the design and implementation of CSCM from three stages (design, implementation and report) with 20 technical points, which will provide technical support for future CSCM studies.

Study and opinion on toxicity of aristolochic acid / 中国中药杂志

On October 18th, 2017, a research article named "Aristolochic acids and their derivatives are widely implicated in liver cancers in Taiwan and throughout Asia" was published on Science Translational Medicine. This article pointed out that herbs containing aristolochic acids could cause liver cancer by inducing the specific "aristolochic acids mutational signature". The public was also suggested to avoid the intake of herbs containing aristolochic acids. Since 2000, CFDA has gradually abolished the medicinal standards for herbs containing aristolochic acids such as caulis aristolochiae manshuriensis, aristolochia heterophylla and radix aristolochiae. Related drugs have been strengthened supervision since then. Chinese Pharmacopoeia has also removed the records of a series of related herbs. State Administration of Traditional Chinese Medicine held a conference on the "toxicity" of aristolochic acids as soon as the article was published. After a discussion of the studies on the toxicity of aristolochic acids, experts attending the meeting discovered several problems, including the unclearness of exposure history, tumor-producing dose and latent period, the absence of some key factors such as hepatitis B, the small sample size, miscellaneous factors, incomplete evidence chains, the missing of analyses between data with huge differences, the insufficiency of fundamental research arguments, etc. In order to understand the toxicity of aristolochic acids and the carcinogenic risks, as well as guide clinical safe medication, the experts suggested that：①Complete the systematical evaluation of aristolochic acids carcinogenicity as soon as possible. Scientifically elucidate the relationship between aristolochic acids and the genesis of liver cancer. ②Establish medication risk warnings of aristolochic acids and strengthen the supervision. ③Make an in-depth study of the toxicity of traditional Chinese medicine. Find out the adverse effects of all traditional Chinese medicine step by step.

Development and application of component-based Chinese medicine theory / 中国中药杂志

Traditional Chinese medicine (TCM) prescription is the main therapies for disease prevention and treatment in Chinese medicine. Following the guidance of the theory of TCM and developing drug by composing prescriptions of TCM materials and pieces, it is a traditional application mode of TCM, and still widely used in clinic. TCM prescription has theoretical advantages and rich clinical application experience in dealing with multi-factor complex diseases, but scientific research is relatively weak. The lack of scientific cognition of the effective substances and mechanism of Chinese medicine leads to insufficient understanding of the efficacy regularity, which affects the stability of effect and hinders the improvement of quality of Chinese medicinal products. Component-based Chinese medicine (CCM) is an innovation based on inheritance, which breaks through the tradition of experience-based prescription and realize the transformation of compatibility from herbal pieces to components. CCM is an important achievement during the research process of modernization of Chinese medicine. Under the support of three national "973" projects, in order to reveal the scientific connotation of the prescription compatibility theory and develop innovative Chinese drugs, we have launched theoretical innovation and technological innovation around the "two relatively clear", and opened up the research field of CCM. CCM is an innovation based on inheritance, breaking through the tradition of experience based prescription, and realizing the transformation from compatibility of herbal pieces to component compatibility, which is an important achievement of the modernization of traditional Chinese medicine. In the past more than 10 years, with the deepening of research and the expansion of application, the theory and methods of CCM and efficacy-oriented compatibility have been continuously improved. The value of CCM is not only in developing new drug, more important is to build a communication bridge between traditional Chinese medicine and modern science and construct the system of key technologies which meet the need of innovation and development of TCM. This paper focused on the research progress, related concepts and technology development of CCM, as well as its application prospect in the theory research of Chinese medicine, development of innovative Chinese drugs, secondary development of Chinese patent medicine and upgrading of pharmaceutical technology.

Risk control of traditional Chinese medicines containing aristolochis acids (AAs) based on influencing factors of content of AAs / 中国中药杂志

Aristolochic acids (AAs) widely exist in such plants as Aristolochia and Asarum. The renal toxicity of AAs as well as its carcinogenicity to urinary system have been widely known. In 2003 and 2004, China prohibited the use of Aristolochiae Radix, Aristolochiae Manshuriensis Caulis and Aristolochiae Fangchi Radix, and required administering other AAs-containing medicines in accordance with the regulations for prescription drugs. In this paper, we retrieved literatures on the content determination of AAs in recent 10 years in China. It suggested that the AAs content is lower in Asarum herb, especially in its roots and rhizomes, and most of which do not show detectable amount of AA-I. Some of traditional Chinese medicines show fairly small amount of detectable AA-I. The AAs content in Aristolochia herb (including Fructus Aristolochiae, kaempfer dutchmanspipe root) is relatively high; however, there are fewer literatures for studying the content determination of AAs in Chinese patent medicines. There were many factors affecting AAs content, including the parts used, origins, processing methods, extraction process. It suggested that we should pay attention to the toxicity of Chinese medicines containing AAs and use these decoction pieces and traditional Chinese medicines cautiously. In addition, basic studies for the origins, processing methods and extraction process of Chinese patent medicines containing AAs, as well as supervision and detection of AAs content in traditional Chinese medicinal materials, decoction pieces and Chinese patent medicines shall be strengthened for reducing medication risk and guaranteeing clinical medication safety.

Consensus-based recommendations for case report in Chinese medicine (CARC) / 中国结合医学杂志

Case reports are valuable clinical evidence in traditional Chinese medicine (TCM). However, the general reporting quality is suboptimal. A working group comprising 20 members was set up to develop systematic recommendations on case report in Chinese medicine (CARC). The working group (CARC group) developed a primary checklist based on reviewing the general reporting quality of case reports in TCM and thorough internal discussion. Two-round consensus process had been carried out among clinical experts, evidence-based medicine methodologists, medical journal editors and clinical practitioners with designated questionnaire embedded with the primary checklist. In total, 118 participants from 17 provinces of China and Korea completed the questionnaires. Their feedback was analyzed and discussed by the CARC group. The checklist was amended accordingly, and the final version, comprising 16-item, is presented here. Under the framework of CARC recommendations, the reporting quality of case reports in TCM can be improved.
