RESUMEN

Coronavirus disease (COVID-19) caused by SARS-COV-2 infection has been widely prevalent in many countries and has become a common challenge facing mankind. Traditional Chinese medicine (TCM) has played a prominent role in this pandemic, and especially TCM with the function of "heat-clearing and detoxifying" has shown an excellent role in anti-virus. Fufang Shuanghua oral liquid (FFSH) has been used to treat the corresponding symptoms of influenza such as fever, nasal congestion, runny nose, sore throat, and upper respiratory tract infections in clinic, which are typical symptoms of COVID-19. The content of chlorogenic acid, andrographolide and dehydrated andrographolide as the quality control components of FFSH is not less than 1.0 mg/mL, 60 µg/mL and 60 µg/mL respectively. In this study, UPLC-Q-TOF-MS/MS was employed to describe the chemical profile of FFSH. Virtual screening and fluorescence resonance energy transfer (FRET) were used to screen the effective components of FFSH acting on SARS-CoV-2 main protease (Mpro). As a result, 214 compounds in FFSH were identified or preliminarily characterized by UPLC-Q-TOF-MS/MS, and 61 active ingredients with potential inhibitory effects on Mpro were selected through receptor-based and ligand-based virtual screening. In particular, quercetin, forsythoside A, and linoleic acid showed a good inhibitory effect on Mpro in FRET evaluation with IC50 values of 26.15 µM, 22.26 µM and 47.09 µM respectively, and had a strong binding affinity with the receptor Mpro (6LU7) in molecular docking. CYS145 and HIS41 were the main amino acid residues affected by small molecules in the protein binding domain. In brief, we characterized, for the first time, 214 chemical components in FFSH, and three of them, including quercetin, forsythoside A and linoleic acid, were screened out to exert beneficial anti-COVID-19 effects through CYS145 and HIS41 sites, which may provide a new research strategy for TCM to develop new therapeutic drugs against COVID-19.

RESUMEN

14-3-3 proteins are important proteins in plants, as they regulate plant growth and development and the response to biotic or abiotic stresses. In this study, a 14-3-3 gene(GenBank accession: OM683281) was screened from the cDNA library of the medicinal species Salvia miltiorrhiza by yeast two-hybrid and cloned. The open reading frame(ORF) was 780 bp, encoding 259 amino a cids. Bioinformatics analysis predicted that the protein was a non-transmembrane protein with the molecular formula of C_(1287)H_(2046)N_(346)O_(422)S_9, relative molecular weight of 29.4 kDa, and no signal peptide. Homologous sequence alignment and phylogenetic tree analysis proved that the protein belonged to 14-3-3 family and had close genetic relationship with the 14-3-3 proteins from Arabidopsis thaliana, Oryza sativa, and Nicotiana tabacum. The 14-3-3 gene was ligated to the prokaryotic expression vector pGEX-4 T-1 and then transformed into Escherichia coli BL21 for the expression of recombinant protein. Real-time fluorescent quantitative PCR showed that the expression of this gene was different among roots, stems, leaves, and flowers of S. miltiorrhiza. To be specific, the highest expression was found in leaves, followed by stems, and the lowest expression was detected in flowers. S. miltiorrhiza plants were treated with 15% PEG(simulation of drought), and hormones salicylic acid, methyl jasmonate, and ethephon, respectively, and the expression of 14-3-3 gene peaked at the early stage of induction. Therefore, the gene can quickly respond to abiotic stresses such as drought and plant hormone treatments such as salicylic acid, jasmonic acid, and ethylene. This study lays the foundation for revealing the molecular mechanism of 14-3-3 protein regulating tanshinone biosynthesis and responding to biotic and abiotic stresses.

RESUMEN

Xuanfu Daizhe Decoction, first seen in Zhang Zhongjing's Treatise on Cold Damage Diseases, was composed of seven medicinal materials: Inulae Flos, Glycyrrhizae Radix, Ginseng Radix, Zingiberis Rhizoma Recens, Haematitum, Pinelliae Rhizoma and Jujubae Fructus. It was used to treat gastric fullness and hardness and belching due to the wrong treatment of typhoid fever and sweating. With detailed records and description in ancient medical books, Xuanfu Daizhe Decoction was widely adopted in clinical practice by physicians of later generations, which expanded its main therapeutic functions. By comprehensive collation of ancient and modern literature on Xuanfu Daizhe Decoction, this paper systematically explored the historical evolution of the prescription from the source, composition, dosage, processing, clinical application, function interpretation and decocting method. It was found that the composition and processing method of the prescription in the past dynasties were relatively consistent, and there was a gradual decrease in dosage in clinical application. In ancient times, Xuanfu Daizhe Decoction was mainly used to treat nausea, vomiting, hiccups, constipation, etc., while modern clinicians mainly used it for digestive diseases such as reflux esophagitis and gastritis. Through the analysis and textual research, the composition, dosage, processing, function evolution and decocting method of this prescription were determined, which provided reference for the research and development of compound preparations of Xuanfu Daizhe Decoction.

RESUMEN

Good agricultural practices(GAP) for Chinese herbal medicine(CHM) is the source of quality control in the production of CHM. To ensure the safety, efficacy, and quality of Chinese herbal and natural medicine, the international community has been exploring the implementation of GAP for CHM. The implementation of GAP for CHM has a far-reaching impact, and the scale planting of CHM has been expanding. However, the medicinal materials produced by the GAP bases for CHM still cannot fully meet the market demand, and the output and quality of CHM remain to be improved. This paper summarizes construction status of GAP bases for CHM.The 129 companies that passed the certification during the implementation of GAP for CHM included 196 GAP bases, forming the scale CHM production zone with Sichuan province, Yunnan province, Jilin province, Henan province, and Shandong province as the core.The total area of GAP bases for CHM in China is about 250 000-500 000 Mu(1 Mu≈667 m2), which is still less than 1% of the total production area of CHM. The international agricultural production quality management strategies are all market-oriented behaviors.Drawing on the international good agricultural and collection practice(GACP) and hazard analysis critical control point(HACCP) as well as the relevant policies of Chinese quality management of CHM, we put forward feasible suggestions for the further implementation of GAP for CHM:(1)The market rules and international experience should be followed and employed to promote GAP management of CHM and third-party implementation of GAP certification;(2)The sound development of GAP for CHM should be boosted with the HACCP management system and the revision of GAP for CHM;(3)The implementation of policies and standards should be stepped up to facilitate the building of a whole-course traceability system for the production of CHM with high quality and reasonable prices.

RESUMEN

This study aims to explore the efficacy of Chinese medicine injections( CMIs) for promoting blood circulation and removing blood stasis for acute cerebral infarction from the perspectives of clinical medication and mechanism of action based on two complex network analysis methods. Firstly,the current 13 kinds of CMIs for acute cerebral infarction were obtained from 2019 List of medicines for national basic medical insurance,industrial injury insurance and maternity insurance with the method of network Meta-analysis. Secondly,with the use of network pharmacology,the mechanisms of top 2 CMIs with the highest therapeutic effect for acute cerebral infarction were explored from two levels including core target and network function enrichment. The result of network Meta-analysis showed Mailuoning Injection was superior to Danhong Injection in terms of total effectiveness rate for neurological deficit score and NIHSS score. The network pharmacology results showed that Mailuoning Injection had more core targets,interaction networks,enriched biological functions and more signaling pathways than Danhong Injection for cerebral infarction. Both two CMIs can play a role in treating cerebral infarction through core targets such as TP53 and NOS3,biological processes such as fibrinolysis,nitric oxide biosynthesis,nitric oxide-mediated signal transduction,negative regulation of apoptosis in endothelial cells and apoptosis process,as well as the signaling pathways such as PI3 K-Akt signaling pathway,HIF-1 signaling pathway and cell apoptosis signaling pathways. The results of pharmacological studies explained their differences in clinical efficacy to a certain extent. A research strategy based on curative effect should be advocated in efficacy evaluation of traditional Chinese medicine,where comparative research on clinical efficacy can be conducted firstly,and then mechanism research based on outstanding effective drugs to better provide references and basis for selection of similar competitive drugs for one disease in the clinical practice.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Aconitum carmichaelii Debeaux, a famous traditional medicinal herb for collapse, rheumatic fever, and painful joints, always raises global concerns about its fatal toxicity from toxic alkaloids when improperly processed. Therefore, it is urgent to clarify the internal molecular mechanism of processing detoxification on Aconitum and develop simple and reliable approaches for clinical application, which is also of great significance to the rational medicinal use of Aconitum. AIM OF THE STUDY: The study aimed at developing a complete molecular mechanism exploration strategy in complex medicinal herb decocting system, clarifying the internal molecular mechanism of processing detoxification on Aconitum, and exploring valid approaches for detoxification. MATERIALS AND METHODS: Aconiti Lateralis Radix Praeparata (Fuzi) was selected as the model for exploring the complex Aconitum detoxification mechanism using an advanced online real-time platform based on extractive electrospray ionization mass spectrometry. The methods realized the sensitive capture of dynamic trace intermediates, accurate qualitative and quantitative analysis, and real-time and long-term monitoring of multi-components with satisfactory accuracy and resistance to complex matrices. RESULTS: Components in the complex Aconitum decocting system were real-timely characterized and fat meat was discovered and verified to directionally detoxify Aconitum while reserving the therapy effect. More importantly, the dynamic detoxification mechanism in the chemically complex Aconitum decoction was molecularly profiled. A novel reaction pathway based on nucleophilic substitution reaction mechanism was proposed. As confirmed by the theoretic calculations at DFT B3LYP/6-31G (d) levels, fatty acids (e.g., palmitic acid) acted as a green, cheap, and high-performance catalyst and promote the decomposition of toxic diester alkaloids to non-toxic and active benzoyl-monoester alkaloids through the discovered mechanism. CONCLUSION: The study exposed a novel detoxification molecular mechanism of Aconitum and provided an effective method for the safe use of Aconitum, which could effectively guide the development of traditional processing technology and compatibility regulation of the toxic herb and had great value to the modernization and standardization development of traditional medicine.

RESUMEN

At present, most of Chinese patent medicines have problems, such as weak scientific basis, unclear clinical value evaluation, etc., which lead to the lack of sufficient evidence for the entry into the essential medicine list, medical insurance catalog and other important health resource allocation tools. This has a negative impact on the development of traditional Chinese medicine. It is urgent to establish a comprehensive evaluation methodology system of Chinese patent medicine in China. There are at least three reasons including producing evidence for clinical rational use scientifically, developing an objective and transparent selecting strategy, eventuating and highlighting its clinical value. The process and method of health technology assessment(HTA) can provide reference for the establishment of comprehensive evaluation method of Chinese patent medicine. However, HTA is rarely carried out in the field of traditional Chinese medicine. The latest domestic and international research showed that HTA combined with multi-criteria decision analysis(MCDA) can increase the transparency of decision-making and improve the quality of decision-making. The combined two formed the EVIDEM framework, which is conducive to drug selection and its clinical use. In this paper, the EVIDEM framework was introduced to establish the methodology framework of the comprehensive clinical evaluation system of Chinese patent medicine. A preliminary research idea has been put forward. In the future, we can establish a set of comprehensive clinical evaluation methods for Chinese patent medicine in cooperation with relevant national drug decision-making departments and management departments. It is believed that such cooperation could promote the full implementation of the re-evaluation for Chinese patent medicine.

RESUMEN

Coronavirus disease 2019(COVID-19) has attracted great attentions from the whole world. Traditional Chinese medicine(TCM) has been widely used and shown satisfying efficacies in treating all stages of COVID-19. In this study, the molecular interaction networks of different stages of COVID-19(the early, severe, critical and recovery stage) were constructed using the links among symptoms-related genes collected from TCMIP V2.0(http://www.tcmip.cn/), an integrated pharmacology network-computing platform for TCM. Following the network topological feature calculation and functional enrichment analysis, we found that the molecular targets and pathways related with the "immune-inflammation system" were involved throughout all the stages of COVID-19. The severe stage and the critical period of COVID-19 were occupied by a large proportion of inflammatory factors and pathways, suggesting that there might be a cytokine storm in these periods, along with respiratory disorders, cardiopulmonary dysfunction, nervous system disorders, etc. Accordingly, the therapeutic targets and pathways hit by the recommended prescriptions against COVID-19 were also aimed to regulate the balance of immune-inflammation system, nutrient absorption and metabolism, abnormal energy metabolism, the cardio-pulmonary function, nerve system function, etc., which may be related to the therapeutic effects of these prescriptions in terms of several clinical symptoms, such as expiratory dyspnea, chest tightness and shortness of breath, abdominal distension and constipation, sweating and limb cold, dizziness, and irritability, etc. The above findings reflect the integrative actions of TCM characterizing by multiple-components, multiple-targets, multiple-pathways, and multiple-effects. This study systematically constructed the molecular networks of different TCM syndromes during the development and progression of COVID-19 and uncovered the biological basis for symptomatic treatment of TCM. Furthermore, our data revealed the pharmacological mechanisms and the scientific connotation of recommended prescriptions, which may provide supports for the prevention and treatment of COVID-19 using TCM.

RESUMEN

Through consulting the ancient herbs and medical books, combining with modern literature, this paper makes textual research on herbal medicine, and textual research on the name, origin, position and harvest and processing changes of the medicinal herbs in ancient classical prescriptions. According to research, Cinnamon medicinal materials were first listed in the Shennong's Herbal Classic, as the name of "Jungui" and "Mugui". Among them, Jungui has undergone the evolution of "Qungui-Jungui-Tonggui-Jungui". After the Northern and Southern Dynasties, a half-volume fatty "Gui" was added, but the usage of the three was no different. The names of Cinnamomi Ramulus and Cinnamomi Cortex did not appear until the Tang Dynasty, and they were preferably thick-skinned and with no cork cambium, and they were mostly used in the name of "Guixin"; Since the Song and Yuan Dynasties, the medicinal parts of cassia have gradually separated. Cinnamomi Cortex is the trunk bark of sapling or branch bark, the twig is Cinnamomi Ramulus, and the tenderest twig is Liugui, Song Dynasty unified the name as "Guizhi"; After the Ming and Qing Dynasties, Cinnamomi Cortex was used as the trunk bark, and Cinnamomi Ramulus was used as the tender twig; In modern times, the Chinese Pharmacopoeia stipulates that the Cinnamomi Ramulus is the young branch of C. cassia, which is Cinnamomum, and Cinnamomi Cortex was the dried trunk bark. From the plant morphology recorded in the previous herbals and the drawings, combined with the distribution of the origins described in the previous herbals, the mainstream plant used as a medicine in the past generations should be C. cassia, but there are other sect. Cinnamomum plants that are also used in medicine everywhere, such as C. chekiangensis, C. bejolghota, C. wilsonii, etc. Throughout the ages, different plant morphologies and medicinal traits have been used to distinguish different categories. The origins of the past dynasties are mostly present in Guangdong, Guangxi province and Vietnam, and are regarded as authentic. The methods for the harvest and processing of cinnamon medicinal materials are basically the same from ancient to modern times.

RESUMEN

In this research, high-throughput sequencing was used to investigate the mechanism of Naoxintong Capsules(NXTC) in prevention of post-ischemic inflammation. First, microglia BV-2 inflammatory model was induced by 1.0 µg·mL~(-1) LPS to investigate the effect of intestinal absorption solution of NXTC(NXTCIA) at different concentrations(62.5, 31.25, 15.63, 7.81 µg·mL~(-1)) on LPS-induced BV-2 inflammatory factors in microglia. Then, an RNA-Seq high-throughput sequencing method was performed to identify the differentially expressed mRNAs in microglia BV-2 after pre-treatment with NXTC. GO and KEGG enrichment analysis was used to screen the potential biological processes and related signaling pathways of NXTC in inhibiting inflammation. The results showed that four NXTCIA concentrations could significantly inhibit the release of LPS-induced inflammatory mediators in BV-2 in a dose-dependent manner. Furthermore, high-throughput sequencing results showed that 392 mRNA transcripts were reversed following pre-treatment with NXTC. GO enrichment analysis showed that the transcripts reversed by NXTC were mainly involved in Toll-like receptor signaling pathway, chemokine signaling pathway, and TNF signaling pathway. Taken together, our findings showed that NXTC treatment could provide protective effects against inflammatory response and the mechanism might be related to the regulation of Toll-like receptor signaling pathway, chemokine signaling pathway, and TNF signaling pathway.

RESUMEN

The paper analyzed the combined administration of traditional Chinese medicine Shuguan Granules, and studied its six plant herbs, namely Polygoni Multiflori Radix, Salviae Miltiorrhizae Radix et Rhizoma, Polygonati Rhizoma, Chuanxiong Rhizoma, Epomedii Folium, and Carthami Flos by network pharmacology analysis, in order to define chemical constituents and drugs targets through integrated pharmacology platform. Based on the results, indications of Shuguan Granules were collected through the ETCM database. Therefore, the present study could determine the potential optimal indications of the drug. The results showed that chest apoplexy was the main traditional Chinese medicine(TCM) symptom treated by Shuguan Granules, whose monarch drug was Salviae Miltiorrhizae Radix et Rhizoma. Network pharmacology analysis found that the target enrichment results of Shuguan Granules were related to the indications of coronary heart disease, angina and atherosclerosis. According to the indications, angina may be the best indication for Shuguan Granules. The 229 components in Shuguan Granules involved a total of 109 core targets, of which TNF and MMP9 were the direct targets to the angina disease. In addition, Shuguan Granules could also indirectly intervene in the progression of angina through MAPK, NFKB, GF and other targets. The main pathways involving angina pectoris are PI3 K-Akt signaling pathway, RAS signaling pathway, TNF signaling pathway, Estrogen signaling pathway and glycolysis/gluconeogenesis, which can intervene in many aspects of angina, such as inflammatory reaction, blood lipid metabolism and vasodilation.

RESUMEN

Traditional Chinese medicine (TCM) is not only an effective solution for primary health care, but also a great resource for drug innovation and discovery. To meet the increasing needs for TCM-related data resources, we developed ETCM, an Encyclopedia of Traditional Chinese Medicine. ETCM includes comprehensive and standardized information for the commonly used herbs and formulas of TCM, as well as their ingredients. The herb basic property and quality control standard, formula composition, ingredient drug-likeness, as well as many other information provided by ETCM can serve as a convenient resource for users to obtain thorough information about a herb or a formula. To facilitate functional and mechanistic studies of TCM, ETCM provides predicted target genes of TCM ingredients, herbs, and formulas, according to the chemical fingerprint similarity between TCM ingredients and known drugs. A systematic analysis function is also developed in ETCM, which allows users to explore the relationships or build networks among TCM herbs, formulas,ingredients, gene targets, and related pathways or diseases. ETCM is freely accessible at http://www.nrc.ac.cn:9090/ETCM/. We expect ETCM to develop into a major data warehouse for TCM and to promote TCM related researches and drug development in the future.

RESUMEN

By using the traditional Chinese medicine inheritance support system (TCMISS) in this study, the prescription rules of Baizhi formulae were analyzed and the core herbal pair "Baizhi-Chuanxiong" was obtained. Through the systemic analysis of prescription rules of "Baizhi-Chuanxiong" and combined with the pharmacology thinking of "Baizhi-Chuanxiong" in treating headache, the paper was aimed to find out the combination rules containing Baizhi andits molecular mechanisms for treating headaches, and provide the theory basis for further research and reference of Baizhi and its formula. Totally 3 887 prescriptions were included in this study, involving 2 534 Chinese herbs. With a support degree of 20% in analysis, 16 most commonly used drug combinations were screened, which were mainly used to treat 15 types of diseases. Baizhi was often used to treat headache, and the core combination "Baizhi-Chuanxiong" was also often used to treat, consistent with ancient record. A chemical database was established; then the headache and migraine disease targets were retrieved and added in the database to build up the "compounds-targets-pathways "core network of "Baizhi-Chuanxiong" by the internet-based computation platform for IP of TCM (TCM-IP). TCM-IP was then applied to study the molecular mechanism of "Baizhi-Chuanxiong" treatment of headache. The results suggested that37 chemical compounds in the core combination "Baizhi-Chuanxiong" were closely related with headache treatment by adjusting serotonin levels or applying to inflammation-related targets and energy metabolism pathways such as purine metabolism, pyruvate metabolism, fatty acid degradation, carbon metabolism and gluconeogenesis.

RESUMEN

Guanxinjing capsules (GXJCs) are used in traditional Chinese medicine as a common therapy for coronary heart disease (CHD) complicated with depression. In this study, we aimed to identify the main active constituents in GXJCs and to investigate the mechanisms of GXJC action on CHD complicated with depression. The chemical constituent profile of the GXJC was identified by UHPLC-LTQ-Orbitrap assay, and oral bioavailability was evaluated to screen the GXJC drug-like chemical constituents. A total of 16 GXJC drug-like chemical constituents were identified. Then, putative targets of the GXJC drug-like chemical constituents were predicted using MedChem Studio, with 870 genes found to be the putative targets of these molecules. After that, a GXJC putative target-known CHD/depression therapeutic target network was constructed, and four topological features, including degree, betweenness, closeness and K-coreness, were calculated. According to the topological feature values of the GXJC putative targets, 14 main active constituents were identified because their corresponding putative targets had topological importance in the GXJC putative target-known CHD/depression therapeutic target network, which were defined as the candidate targets of GXJC against CHD complicated with depression. Functionally, these candidate targets were significantly involved in several CHD/depression-related pathways, including repairing pathological vascular changes, reducing platelet aggregation and inflammation, and affecting patient depression. This study identified a list of main active constituents of GXJC acting on CHD complicated with depression using an integrative pharmacology-based approach that combined active chemical constituent identification, drug target prediction and network analysis. This method may offer an efficient way to understand the pharmacological mechanisms of traditional Chinese medicine prescriptions.

RESUMEN

Cytokines can be divided into two types: proinflammatory cytokines and anti-inflammatory cytokines. Proinflammatory cytokines are a kind of small molecular peptides synthesized and excreted by immune and non-immune cells, which can regulate a variety of physiological functions and play an important role in the process of trauma, pain and infection. Proinflammatory cytokines include TNF, IL-1, IL-6 and IL-8. More and more evidences suggest that proinflammatory cytokines(PICs), such as interleukin-1ß(IL-1ß), interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α), are induced in the spinal cord(SC) and dorsal root ganglion (DRG) under various injury conditions, and contribute to pain hypersensitivity. In recent years, with the deepening of studies on neuropathic pain mechanism and the increasing expansion of the neuroinflammation study field, the action mechanisms of cytokines and molecules in regulating cytokines in neuropathic pain are expected to provide new targets for the development of analgesic drugs. This review aims to provide an overview of inflammatory mechanisms for proinflammatory cytokines TNF-α, IL-1ß, IL-6, with a focus on neuropathic pain.

RESUMEN

Recently, integrative pharmacology(IP) has become a pivotal paradigm for the modernization of traditional Chinese medicines(TCM) and combinatorial drugs discovery, which is an interdisciplinary science for establishing the in vitro and in vivo correlation between absorption, distribution, metabolism, and excretion/pharmacokinetic(ADME/PK) profiles of TCM and the molecular networks of disease by the integration of the knowledge of multi-disciplinary and multi-stages. In the present study, an internet-based Computation Platform for IP of TCM(TCM-IP, www.tcmip.cn) is established to promote the development of the emerging discipline. Among them, a big data of TCM is an important resource for TCM-IP including Chinese Medicine Formula Database, Chinese Medical Herbs Database, Chemical Database of Chinese Medicine, Target Database for Disease and Symptoms, et al. Meanwhile, some data mining and bioinformatics approaches are critical technology for TCM-IP including the identification of the TCM constituents, ADME prediction, target prediction for the TCM constituents, network construction and analysis, et al. Furthermore, network beautification and individuation design are employed to meet the consumer's requirement. We firmly believe that TCM-IP is a very useful tool for the identification of active constituents of TCM and their involving potential molecular mechanism for therapeutics, which would wildly applied in quality evaluation, clinical repositioning, scientific discovery based on original thinking, prescription compatibility and new drug of TCM, et al.

RESUMEN

To estabish ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for simultaneous determination of quercetin(QCT), isorhamnetin(ISR), kaempferol(KMF), ginkgolide A(GA), ginkgolide B(GB), ginkgolide C(GC) and bilobalide(BB) in rat plasma and investigate the pharmacokinetic process of seven compounds after oral administration of Yindan Xinnaotong Ruanjiaonang, The results indicated that all calibrations curves showed good linearity (r≥0.997 1). RSD of intra-day and inter-day precisions were all within 11%. The matrix effects and extraction recovery were in the range of 93.28%-103.6% and 72.43%-95.77% respectively. The peak concentration (Cmax) of QCT, ISR, KMF, GA, GB, GC and BB were (45.02±11.28), (49.90±13.82), (27.85±8.38), (76.31±18.19), (76.54±15.43), (35.35±10.28), (48.70±12.34) µg•L⁻¹, respectively. The peak time (tmax) of seven constituents were (0.33±0.11), (0.50±0.23), (0.33±0.14), (0.75±0.29), (1.0±0.35), (1.5±0.23), (0.75±0.50) h, respectively. UPLC-MS/MS method established in this research was proved to be so rapid and sensitive that it can be applied to the pharmacokinetic study of seven bioactive constituents in Yindan Xinnaotong Ruanjiaonang.

RESUMEN

To analyze the prescription rules of preparations containing Crataegi Fructus in the drug standards of the People's Republic of China Ministry of Public Health-Chinese Patent Drug(hereinafter referred to as Chinese patent drug), and provide some references for clinical application and the research and development of new medicines. Based on TCMISS(V2.5), the prescriptions containing Crataegi Fructus in Chinese patent drug were collected to build the database; association rules, frequency statistics and other data mining methods were used to analyze the disease syndrome, common drug compatibility and prescription rules. There were a total of 308 prescriptions containing Crataegi Fructus, involving 499 kinds of Chinese medicines, 34 commonly used drug combinations, and mainly for 18 kinds of diseases. Drug combination analysis was done with "Crataegi Fructus-Citri Reticulatae Pericarpium" and "Crataegi Fructus-Poria" as the high-frequency herb pairs and with "stagnation" and "diarrhea" as the high-frequency diseases. The results indicated that the Crataegi Fructus in different herb pairs had a roughly same function, and its therapy effect was different in different diseases. The prescriptions containing Crataegi Fructus in Chinese patent drug had the effect of digestion, and they were widely used in clinical application, often used together with spleen-strengthening medicines to achieve different treatment effects; the prescription rules reflected the prescription characteristics of Crataegi Fructus for different diseases, providing a basis for its clinically scientific application and the research and development of new medicines.
