RESUMO

Chromatography is an important branch of analytical chemistry that focuses on the separation and analysis of complex structures. Following more than 100 years of development and improvement, chromatography theory and technology have gradually become sophisticated. It has become a coalition of science, technology, and art. Recently, chromatography has been successfully used in combination with mass spectrometry, nuclear magnetic resonance spectroscopy, and atomic emission spectroscopy. Chromatography and the combination with other techniques has significantly improved the analysis of complex systems, such as the environment, food, petrochemicals, biological specimens, and medicine. As one of the oldest healing systems, Traditional Chinese Medicine (TCM) has served to maintain the health of people in China and worldwide for thousands of years. Therefore, it has become a core representative of traditional Chinese culture. In the past two years, TCM has been widely used to treat COVID-19, especially in patients with mild symptoms. Recently, Chinese government emphasized the inheritance and innovation of TCM and stepped up efforts to promote its modernization. TCM includes herbal medicine, acupuncture, moxibustion, massage, food therapy, and physical exercise, such as Tai Chi. In most cases, the patients are administered a mixture of TCM formulas containing more than two herbal medicines, resulting in a highly complicated compound mixture. There is no doubt that long-term clinical practices have demonstrated the safety and therapeutic effect of TCM. However, the compound mixture must be simplified to identify the active compounds. This is mainly because of the existence of carcinogenic compounds, pesticides, and heavy metal residues introduced through plantation and production processes. Moreover, enzymes within the human system generate further new compounds in response to the entry of the TCM containing thousands of components. Consequently, the complex TCM and organism systems interact with each other, constituting a giant complex drug-organism system. The analysis of this giant complex system is acknowledged as a key aspect in the modernization process of TCM. In the last 20 years, many studies have been conducted to screen and identify effective compounds in TCM. These effective compounds can be either the original compounds or new metabolic components generated in vivo. All these efforts are aimed at simplifying the components of TCM and elucidating the therapeutic mechanism. It is well known that chromatography can provide technical support for complex systems owing to its unique advantage of outstanding separation and analysis capabilities. Therefore, chromatography and its combination with other technologies have become mainstream technologies for promoting the compilation of molecular structure, information, digitalization, and modernization of TCM. This paper reviews the research and application of chromatography and combination technologies in a giant complex TCM formula-organism system. Furthermore, the authors briefly introduce and summarize the understanding, research ideas, and activities of the authors' team on the modernization of TCM. "Liang Guanxi" and "He strategy" are proposed as novel strategies for studying the giant complex drug-organism system. A distinguished technology integrated with mathematical model of causal relation, combined receptor chromatography, identification of chemical molecular structure and evaluating of pharmacological activities was established. It was successfully employed to determine the core effector-response substances of "Liang Guanxi" herb pairs in a giant complex drug-organism system. Subsequently, utilizing the proposed technology of Combination of Traditional Chinese Medicine Molecular Chemistry, the author's team designed and developed four series of innovative drugs. Inspired by the hundred years of chromatography history and thousands of years of TCM culture, the future development of chromatographic technology is expected. Furthermore, the mechanisms of TCM in medical healthcare, prevention, and treatment of diseases are likely be explained through chromatography, leading to a new strategy to realize the molecularization and digitalization of TCM, which is beneficial to the development of original new drugs.

RESUMO

BACKGROUND: Traditional Chinese medicine (TCM) has shown excellent therapeutic effects in the treatment of heart diseases. This meta-analysis was to evaluate the therapeutic effects of TCM on patients with atrial fibrillation (AF). METHODS: Four databases were searched from their establishment to 1 April 2021 for randomized controlled trials (RCTs) on the treatment of AF using TCM. The Cochrane Handbook 5.0.2 was used to perform to bias risk assessment, and RevMan 5.3 was used for meta-analysis. RESULTS: A total of 7 references were included. It was found that compared with conventional Western medicine, the effective rate of TCM or the combined therapy of TCM and Western medicine was higher [mean difference (MD) =1.85; 95% confidence interval (CI): 1.28 to 2.68; Z=3.26; P=0.001]; the success rate of conversion was increased (MD =1.58; 95% CI: 1.02 to 2.44; Z=2.06; P=0.04), the conversion time was shortened (MD =-224.82; 95% CI: -262.56 to -187.08; Z=11.68; P<0.00001), the incidence of adverse reactions was reduced (MD =0.62; 95% CI: 0.40 to 0.97; Z=2.11; P=0.03). DISCUSSION: The use of TCM to treat AF can improve clinical treatment efficiency, increase the success rate of conversion, and shorten the conversion time. Compared with conventional Western medicine, the combined therapy demonstrated better therapeutic effects.

RESUMO

The large-scale exchange and spread of traditional Chinese medicine (TCM) in the West began in the 17th century. From the first English Chinese medicine book "gout collection" published in London in 1676, the British began to understand the mysterious and ancient oriental medicine of TCM. Britain is one of the earliest countries where TCM began to spread. TCM is an important carrier of China's excellent traditional culture. With the development of the world's medical technology and the continuous improvement of China's cultural soft power, the cross-cultural communication of TCM has become a characteristic business card for China to go to the world. For the research of a work, we must start from the source, so it is very important to first count the history of TCM external communication, and then systematically analyze and study the various phenomena in this history, so as to summarize the experience and inadequacy of TCM external communication process, and provide feasible guidance for future TCM research, And promote the effective development of TCM, and ultimately spread TCM culture to the international community more comprehensively and accurately. Although the greater than 300 hundred years' history of traditional Chinese medicine (TCM) spreading throughout Britain has been continuously mentioned in literature, studies on the historical development of TCM in Britain are rare. In this paper, the authors gathered information including the chronological statistics and stages of the 300 hundred years' dissemination of TCM in Britain, in order to provide more historical data and research materials for the spread of Chinese medicine in Britain.

RESUMO

BACKGROUND: Constipation is one of the common complications of thoracolumbar compression fractures, which seriously affects the quality of life and increases pain of patients. External treatment of traditional Chinese medicine (TCM) has been widely used clinically for constipation after thoracolumbar compression fractures, but there are no systematic review and meta-analysis of its efficacy. Therefore, we will conduct this study to systematically evaluate the clinical effects of external treatment of TCM for patients with constipation after thoracolumbar compression fractures. METHODS: We will search the following electronic databases: PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infastructure, Chinese Biomedical Literatures Database, Chinese Scientific Journal Database, and Wanfang Database. Randomized controlled trials on the treatment of constipation after thoracolumbar compression fractures with external treatment of TCM published from inception to May 2021 will be included in the search scope. The observation group was treated with Simple external treatment of TCM (such as external application of Chinese medicine, Chinese drugs at the acupoint, acupuncture, moxibustion, etc) or external treatment of TCM combined with conventional treatment/nursing of Western medicine, while the control group only was treated by conventional treatment/nursing of Western medicine. After screening literatures, extracting data, and assessing the risk of bias in the included studies, meta-analysis will be performed by Revman 5.3 software. RESULTS: This study is expected to provide an evidence of the efficacy of external treatment of TCM for constipation after thoracolumbar compression fractures. CONCLUSION: The results of this meta-analysis may help provide evidence to determine whether external treatment of TCM can be effective interventions for thoracolumbar compression fractures patients with constipation. TRIAL REGISTRATION NUMBER: INPLASY202150005.

RESUMO

As a new strategy capable of uncovering the characteristics of traditional Chinese medicines, the quantitative analysis of multi-components by single-marker(QAMS) has been widely employed for the quality evaluation of Chinese medicinal materials, slices, and extracts. However, its application in the assessment of Chinese patent medicines is yet to be explored. By referring to the determination of three bufogenins in Bufonis Venenum by QAMS described in Chinese Pharmacopoeia(2020 Edition), this paper selected seven representative preparations containing Bufonis Venenum and explored whether the relative correction factors(RCFs) of cinobufagin(CB) to bufalin(BF) and resibufogenin(RB) could be directly used for the quality control of Bufonis Venenum-contained preparations. Based on the qualitative analyses under the same chromatographic conditions as used for toad venom, combing specificity test, five preparations such as Yatong Yili Pills, Houzheng Pills, Xiongdan Jiuxin Pills, Liushen Pills and Niuhuang Xiaoyan Pills, were expected to use validated RCFs for the direct determination of three components. Taking Houzheng Pills as an example, the methodological validation of bufalin, cinobufagin and resibufogenin was carried out, and the recoveries of bufalin, cinobufagin and resibufogenin were 90.64%-106.1%. The obvious difference was not observed between the contents of bufalin and resibufogenin in 24 batches of preparation samples by QAMS and external reference method. In the tested samples, the content of bufalin, cinobufagin and resibufogenin were 1.27-2.61, 2.44-5.66 and 0.988-3.16 mg·g~(-1) in 10 batches of Liushen Pills samples. The contents of bufalin, cinobufagin and resibufogenin were 0.760-1.32, 1.35-2.39 and 0.600-1.55 mg·g~(-1) in 10 batches of Houzheng Pills samples from three manufacturers. The obtained data contribute to improving the quality standard of Bufonis Venenum-contained preparations, and they also provide some ideas for the application of QAMS in the quality evaluation and control of Chinese patent medicines.

RESUMO

To systematically search and sort out the clinical randomized controlled trial(RCT) on the prevention and treatment of acute cerebral infarction with traditional Chinese medicine(TCM) by using the method of evidence map, and to understand the evidence distribution of related studies. CNKI, Wanfang, VIP, CBM, PubMed, EMbase, Cochrane Library and Web of Science were retrieved from January 2016 to September 2020, and literatures related to the prevention and treatment of acute cerebral infarction with traditional Chinese medicine were included. Text description combined with table and bubble chart were used to analyze the distribution characteristics of evidence. A total of 1 102 clinical articles in recent five years were retrieved. The annual trend of clinical study publication, study size, TCM therapy category and main scheme, and study literature quality were analyzed. We find that TCM treatment of acute cerebral infarction has become a hot topic of clinical research, the number of literature showed a trend of increased year by year, various means of intervention of TCM in the treatment of the advantages of increasingly highlight. Follow-up clinical research should highlight the characteristics of TCM: in the analysis of outcome indicators; increase the neuropsychological patients after stroke and cognitive ability, and the theory of combined treatment of TCM disease when thoughts; At the same time, the quality of clinical research needs to be improved. At present, there is still a lack of unified standards for the production of evidence map. This study is the first to explore the application of evidence map to summarize and display the clinical research status of TCM treatment of acute cerebral infarction, and combine it with the setting of priority areas of TCM clinical research, so as to provide a reference basis for determining the priority topic selection of TCM treatment optimization research.

RESUMO

The acupoint application of Euodiae Fructus at Yongquan(KI1) can significantly improve the sleep quality of patients with insomnia with berberine as the main effective component for the efficacy. Nineteen active compounds and 203 drug targets were screened out from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). After comparison with GeneCards and Online Mendelian Inheritance in Man(OMIM), 24 common genes of diseases and drugs were obtained. STRING 11.0 was used to construct a protein-protein interaction(PPI) network of the overlapping genes, and Matthews correlation coefficient(MCC) was employed to screen the core genes, which were then subjected to enrichment analysis with gene ontology(GO) and Kyoto encyclopedia of genes and genomes(KEGG). The results revealed that the main compounds of Euodiae Fructus, such as berberine and rutaecarpine, participated in the biological processes(such as neurotransmitter receptor activity) by regulating C-reactive protein(CRP), estrogen receptor 1(ESR1), 5-hydroxytryptamine(5-HT) receptor, and interleukin-6(IL-6) to exert sedative, anxiolytic, and antidepressant effects. Sixty 4-week-old SPF mice were randomly divided into a control group, a model group, a positive drug(diazepam tablets) group, and low-, medium-, and high-dose berberine groups. Medication with corresponding drugs was performed for one week. The results demonstrated that berberine was potent in reducing the activities and standing times of mice, down-regulating the levels of CRP and IL-6 mRNA in the hypothalamus, and up-regulating the expression of 5-HT(P<0.01); however, no significant effect on ESR1 was observed. The network of Euodiae Fructus in treating insomnia was constructed by network pharmacology and verified by tests. The findings indicated that the therapeutic efficacy of Euodiae Fructus in treating insomnia was achieved by participating in multiple biological processes, such as neurotransmitter receptor activity, which provided a scientific basis for its clinical application.

RESUMO

To explore the potential effective components and mechanism of Zhishe Tongluo Capsules in the treatment of ischemic stroke via network pharmacology, molecular docking and cellular experiment. The chemical constituents of Zhishe Tongluo Capsules were found by TCMSP, BATMAN-TCM and literatures. The constituents-target network was predicted by BATMAN-TCM database. Key words such as cerebral stroke, ischemic stroke and cerebral ischemic stroke were used to search ischemic stroke related targets, and then Venny Map was constructed based on the targets of traditional Chinese medicine and the targets of ischemic stroke. The overlapping targets were imported into STRING database to establish the interaction network. Furthermore, the core targets were screened out by Cytoscape software. Go and KEGG enrichment analysis were performed through DVIAD database. The results showed a total of 193 potential chemical constituents, 985 drug targets and 6 035 disease targets. There were 631 potential targets, 44 core targets and 55 potential active components for treating ischemic stroke through Venny mapping. GO enrichment analysis mainly involved response to hypoxia and positive regulation of ERK1/ERK2. KEGG pathway enrichment analysis mainly involved cholinergic synapse, cAMP signaling pathway, and calcium signaling pathway. Molecular docking data revealed that TP53, EGFR, IL6, INS, TNF and SRC had a good capability to bind with their corresponding active components. To ensure the protective effect Zhishe Tongluo Capsules on the inflammation reaction, an in vitro model of lipopolysaccharide(LPS)-induced RAW264.7 cells was built. The contents of IL-1α, IL-1ß, IL-6 and TNF-α in the supernatant were significantly decreased by enzyme linked immunosorbent assay(ELISA). The findings suggested that Zhishe Tongluo Capsules could prevent the injury of ischemic stroke by inhibiting the inflammation.

RESUMO

Endometriosis(EMs) is a stubborn gynecological disease caused by persistent immune-inflammatory effects, and is known as "benign tumor" because of its similar characteristics to malignant tumors. National physician master Professor BAN Xiu-wen believes that the spread of damp-evil is the pathologic foundation for inflammatory response of ectopic endometrium; accumulation of blood stasis is the pathological product of continuous inflammatory attacks, and the combination of dampness and stasis is the main pathogenesis for refractory EMs. Modern researches have shown that immune-inflammatory effect is the key mechanism for development of EMs, and is closely related to cell autophagy, all of which have made it become the hot spots in research of the pathogenesis, diagnosis and treatment of EMs. Therefore, with immune-inflammatory effect as the breakthrough point in this research, and with reference to the related research of autophagy, the correlation between "combination of dampness and stasis" and abnormal autophagy-induced immune inflammatory response in ectopic endometrium was discussed, to provide guidance for the clinical application of traditional Chinese medicine and modern research.

RESUMO

To study the effect of mineral Chloriti Lapis on pulmonary metabolites and metabolic pathways in lung tissues of rats with acute exacerbation of chronic obstructive pulmonary disease(AECOPD). The AECOPD rat model of phlegm heat syndrome was replicated by the method of smoking combined with Klebsiella pneumoniae infection. Except for using UPLC-Q-TOF-MS analysis, SPSS 18.0, SIMCA 13.0 and other software were also used for statistical analysis. Through literature search and online database comparison, the differential metabolites were identified, and the possible metabolic pathways were analyzed. After 15 days of administration, PLS-DA analysis was carried out on lung tissue samples of rats in each group. The results showed that the metabolic profiles of lung tissues of rats in each group could be well separated, which indicated that Chloriti Lapis and aminophylline had significant intervention effect on the lung metabolic profile of rats with AECOPD. Moreover, the metabolic profile of Chloriti Lapis group was closer to that of control group, and the intervention effect was better than that of aminophylline group. As a result, 15 potential differential metabolites were identified: phytosphingosine, sphinganine, tetradecanoylcarnitine, L-palmitoylcarnitine, elaidic carnitine, lysoPC[18∶2(9Z,12Z)], lysoPC(16∶0), lysoPC[18∶1(9Z)], lysoPC(18∶0), stearic acid, lysoPC(15∶0), arachidonic acid, docosapentaenoic acid, linoleic acid and palmitic acid. Among them, Chloriti Lapis could significantly improve the levels of 10 differential metabolites of phytosphingosine, tetradecanoylcarnitine, L-palmitoylcarnitine, elaidic carnitine, lysoPC[18∶2(9Z,12Z)], lysoPC(16∶0), lysoPC[18∶1(9Z)], stearic acid, lysoPC(15∶0), and palmitic acid(P<0.05). The intervention effect of Chloriti Lapis group was better than that of aminophylline group. Analysis of metabolic pathways showed that there were 8 possible metabolic pathways that could be affected, and three of the most important metabolic pathways(pathway impact>0.1) were involved: linoleic acid metabolism, arachidonic acid metabolism, and sphingolipid metabolism. Chloriti Lapis had obvious intervention effects on lung tissue-related metabolites and metabolic pathways in rats with AECOPD, and the effect was better than that of aminophyllinne.

RESUMO

Tianxiong has been used as a Chinese medicinal in China for thousands of years, and the earliest record can be traced back to the Shennong's Classic of Materia Medica. It is effective in dispersing wind, dissipating cold, and replenishing fire to streng-then yang. To clarify the origin of Tianxiong, the present herbalogical study reviewed the ancient and modern literature from the origin, processing, and clinical efficacy. Before the Tang Dynasty, although the description of Tianxiong was quite superficial, an apparent difference between Tianxiong and Fuzi was recognized. In the Tang and Song Dynasties, Tianxiong and Fuzi were mistakenly recognized to be prepared from a same plant since their raw materials came from artificial cultivation. Medical literature in the Ming and Qing Dynasties mostly followed the previous records, with the origin of Tianxiong remaining controversial. There were three mainstream views about the origin of Tianxiong according the ancient medical books. First, Tianxiong was a kind of Aconiti Radix(Chuanwu) without attachment of Fuzi. Second, Tianxiong was the large Fuzi. Third, Tianxiong derived from Aconiti Kusnezoffii Radix(Caowu) about 10 cm in length. By contrast, Fuzi in a large size was simply regarded as Tianxiong in modern times. The processing methods were diversified in the ancient times, and the fire-processing was continuously applied. With the deepening of the research on the efficacy and detoxification mechanism, more methods were discovered, such as processing with ginger juice, child's urine and alcohol. As for modern times, the processing of Tianxiong has not been nearly passed down. The characteristic processing of Tianxiong only handed down in Sichuan province and Lingnan area, which can be discriminated by the last step. The efficacies of Tianxiong can be directly understood from its literal name, including dispersing wind, dissipating cold, and replenishing fire to assist yang. Nowadays, Tianxiong is mostly used to strengthen yang.

RESUMO

Nucleic acid aptamers, broad-spectrum target-specific single-stranded oligonucleotides, serve as molecules in targeted therapy, targeted delivery and disease diagnosis for the treatment of tumor or microbial infection and clinical detection. Due to the existence of components in the use of traditional Chinese medicine(TCM), the target is difficult to concentrate and the specificity of treatment is poor. The effective components of TCM are toxic components, so a highly sensitive detection method is urgently needed to reduce the toxicity problem at the same time. The combined application of TCM and modern medical treatment strategy are difficult and cannot improve the therapeutic effect. Aptamers, advantageous in biosensors, aptamer-nanoparticles for targeted drug delivery, and aptamer-siRNA chimeras, are expected to connect Chinese medicinals with nanotechnology, diagnostic technology and combined therapies. We summarized the preparation, screening, and modification techniques of nucleic acid aptamers and the biomedical applications and advantages in therapy, targeting, and diagnosis, aiming at providing a reference for the in-depth research and development in TCM.

RESUMO

In recent years, the establishment of the commercial grade of Yinpian [traditional Chinese medicine(TCM) pieces for decoction] in the TCM industry has been hotly disputed. In this article, Sophorae Flavescentis Radix(SFR) was selected as a representative example to investigated. Through systematic comparison and analysis, the different grades of SFR slices were traced, verified and evaluated. According to the current published local grade standards of SFR slices, the results showed that the first-class of SFR slices were mostly derived from the wild medicinal materials, the second-class were mostly originated from the cultivated materials in 3-4 years, and the third-class products were from a small number of lateral roots and short-growing years or harsh habitat of wild medicinal materials. On the basis of identifying the sources of different grades of SFR slices, the contents of the active components, including matrine, oxymatrine, oxysophocarpine, sophoridine, N-methyl-cytisine, sophocarpine, were quantitatively determined in typical samples, it was found that the grades were inversely proportional to the contents of active ingredients. In order to ensure the universality of the conclusion, the contents of different grades of commercial SFR slices were determined, and the conclusion was verified as "the commercial grades of SFR slices were inversely linked to their contents of active ingredients". This phenomenon is common in the determination of the commercial grade of Yinpian of radix and rhizome. Therefore, we propose that the method or standard of the commercial grade of Yinpian of radix and rhizome based on the size of Yinpian maybe not proper. Whether and how to classify Yinpian commercial grade is not only a multi-disciplinary issue, especially in combination with clinical efficacy, but also a big problem need to consider the production, commercial circulation and other processes link of quality risk and quality assurance, and should be treated with great caution.

RESUMO

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.

RESUMO

To systematically evaluate the efficacy and safety of traditional Chinese medicine injections combined with antiviral wes-tern medicine in the treatment of influenza by Bayesian network Meta-analysis. Four Chinese databases(CNKI, Wanfang, VIP, CBM) and three English databases(PubMed, EMbase, Cochrane Library) were retrieved by computer for randomized controlled trials(RCT) about the comparison between the combined administration of traditional Chinese medicine injections with antiviral western medicine(or with placebo) and the single administration of antiviral western medicine in the treatment of influenza, or the comparison between two different traditional Chinese medicine injections combined with antiviral western medicine in the treatment of influenza. The retrieval time was from the establishment of the databases to July 2020. Two researchers independently screen out the literatures and extracted the data according to the inclusion criteria and exclusion criteria. The included studies were evaluated by the Cochrane 5.1 bias risk assessment tool, and data analysis was conducted by ADDIS 1.16.8 and Stata 14.0. A total of 49 literatures about 5 061 cases were included finally, involving six traditional Chinese medicine injections, namely Reduning Injection, Xiyanping Injection, Tanreqing Injection, Yanhuning Injection, Qingkailing Injection and Shuanghuanglian Injection. The results of network Meta-analysis,(1)in terms of total effective rate, 6 traditional Chinese medicine injections combined with antiviral western medicine was better than antiviral western medicine alone. In terms of probability sorting, Shuanghuanglian Injection combined with antiviral western medicine ranked first.(2)There was no significant statistical difference in adverse reaction rate among all groups, but Reduning Injection ranked first in the probability sorting, due to the least side effects.(3)In terms of antipyretic time, Yanhuning Injection, Xiyanping Injection and Tanreqing Injection combined with antiviral western medicine was better than antiviral western medicine alone and Xiyanping Injection ranked first in the probability sorting.(4)In terms of cough relief time, Qingkailing Injection and Tanreqing Injection combined with antiviral western medicine was better than antiviral western medicine alone and Qingkailing Injection was superior to Yanhuning Injection. Qingkailing Injection combined with antiviral western medicine ranked first in the probability sorting.(5)In terms of the length of hospital stay, Xiyanping Injection, Tanreqing Injection and Reduning Injection combined with antiviral western medicine was superior to antiviral western medicine alone, and Reduning Injection ranked first in the probability sorting due to the shortest hospital stay. Because of the small quantity and low quality of included studies, the results of this study shall be regarded cautiously and comprehensively. In the future, multi-center, large-sample and clinical randomized controlled trials shall be conducted to verify the results.

RESUMO

This study evaluated the outcome indicators of the randomized controlled trials(RCTs) of traditional Chinese medicine(TCM) in the treatment of postmenopausal osteoporosis(PMOP) to provide a reference for the related research. Four Chinese databa-ses(CNKI, VIP, Wanfang and CBM) and three English databases(Cochrane Library, EMbase and PubMed) were searched syste-matically to screen RCTs of TCM in the treatment of PMOP according to the pre-set criteria, and the quality of the included trials was evaluated by the Cochrane risk-of-bias tool. A total of 29 627 articles were initially retrieved, and finally, 43 articles were included, including 34 in Chinese and 9 in English. As revealed by the results, the outcome indicators of 43 RCTs were mainly divided into six categories, with biochemical indicators accounting for 54.59%, bone mineral density(BMD) for 26.57%, quality of life for 6.28%, fracture for 1.94%, safety for 5.31%(including adverse reactions or events) and others for 5.31%. Biochemical indicators showed the maximum occurrence, followed by BMD. Many problems were found in the selection of outcome indicators of the TCM RCTs in the treatment of PMOP, such as the confusion of primary and secondary outcome indicators, the lack of endpoint criteria and vital clinical outcome indicators substituted by intermediate indicators, inconsistent evaluation standard of syndrome curative efficacy and neglected blinding in the measurement of subjective outcome indicators. The problems also included importance given to the efficacy indicators instead of the adverse outcome indicators, unnormalized indicator name, large quantitative range of the indicators, unconventional application of TCM efficacy criteria, seldom used confidence interval, relative effect indicator and absolute effect indicator.

RESUMO

The formulation of expert consensus on clinical application of Chinese patent medicines, in means of exploring the effective combination of experience and evidence to form a research method in line with the characteristics of Chinese patent medicines, is an important transitional stage for clinical researches on Chinese patent medicines. Pre-searching is a new step in the formulation of expert consensus on clinical application of Chinese patent medicines. Before steps of interview and investigation on clinical application, pre-searching is conducted to collect publications and literature on certain variety and similar Chinese patent medicines; the publications on related medical classics and formulas of this variety; the recommendation condition of this variety in clinical practice guidelines and expert consensus; and the medication regimens recommended in disease-specific guidelines. Pre-searching is designed to know about the advantages of certain variety of Chinese patent medicine as well as its potential problems recorded in the literature, which is helpful to find out the clinical positioning of Chinese patent medicines, develop reasonable clinical questions and provide ideas for formal literature searching. However, it is not the direct basis for developing clinical questions. Moreover, interviews and investigations are still needed to further clarify the clinical positioning of Chinese patent medicines and develop reasonable questions. This paper took expert consensus on clinical application of Yanshen Jianwei Capsules as an example to introduce the pre-searching process and methods used during formulation of expert consensus on clinical application of Chinese patent medicines, and to further discuss the role of pre-searching to facilitate the formulation of clinical questions on selection of participants, interventions, controls and outcomes.

RESUMO

Fourteen classical prescriptions in the Catalog of 100 Ancient Classical Prescriptions(First Batch) promulgated in 2018 contain Chuanxiong Rhizoma, which reveals the high medicinal value and wide application of Chuanxiong Rhizoma. This paper systematically reviews the ancient herbal books and modern literature to explore the name, origin, genuine producing area, medicinal part, harvesting, and processing of Chuanxiong Rhizoma, thus facilitating the development of classical prescriptions containing Chuan-xiong Rhizoma. It is confirmed that Chuanxiong Rhizoma, formerly known as "Xiongqiong" in Chinese, was first called "Chuanxiong" in late Tang Dynasty, which has been gradually accepted as its official name due to the rise of the status of Chuanxiong Rhizoma produced in Sichuan. The main original plant of Chuanxiong Rhizoma in past dynasties has always been deemed to be Ligusticum chuan-xiong(Umbellifera), whose rhizome serves as the medicinal part. In general, it is best harvested in summer but the harvesting time can vary with different growth environments. Since the Song Dynasty, Sichuan province has been recognized as the genuine producing area of Chuanxiong Rhizoma in light of the high yield and good quality. It is suggested that Chuanxiong Rhizoma from Sichuan be used preferentially in the development of classical prescriptions. There are multiple processing methods of Chuanxiong Rhizoma recorded in ancient medical classics, and the raw(after purifying and slicing) or wine-processed or stir-fried Chuanxiong Rhizoma is still in use today. In the development of classical prescriptions containing Chuanxiong Rhizoma, Chuanxiong Rhizoma is advised to be processed in accordance with current processing standards if the specific processing method is described in the medical classics. If not, the raw Chuanxiong Rhizoma is preferred and then processed following the processing standards of Chuanxiong Rhizoma decoction pieces in Chinese Pharmacopoeia.
