ABSTRACT
Objective To study the correlation among property, efficacy and target of herbal Chinese materia medica; To analyze the molecular mechanism of cold and heat property of Chinese materia medica; To provide references for explaination of microcosmic mechanism and scientific connotation of property of Chinese materia medica. Methods Recordings about property and efficacy of single medicine in 2015 edition of Pharmacopoeia of the People's Republic of China were sorted out. According to Pharmacological Research of New Ideas and New Targets and Pharmacology, 509 kinds of herbal Chinese materia medica were selected. Relevant articles about property, efficacy, pharmacologic action, and target in CNKI and Chinese Academic Journal Database (Wanfang Data) were searched by computers. The target information was screened and standardized, and the database was constructed by using MySQL5.7.13. The correlation between the property, efficacy and the target of the herbal Chinese materia medica was studied by using the frequency analysis and correlation rule algorithm of R software platform 3.3.1. Results 509 kinds of herbal Chinese materia medica were selected, including 227 kinds of cold-property medicine, 106 kinds of neutural-property medicine and 176 kinds of hot-property medicine. According to the result of data mining, efficacy of cold-roperty medicine was quenching thirst, clearing liver and treating stranguriaetc. The target was transforming growth factor β2 and liver microsome, etc. The efficacy of hot-property medicine was warming the middle, releasing cold and dissolving lumps. The target was bone morphology protein 2, rheumatoid factor, etc. The efficacy of neutural-property medicine was clearing lungs, diminishing distension and increasing energy. The target was β-amyloid and prostaglandin E2 receptors. Conclusion There is certain correlation in property, efficacy and target in Chinese materia medica.
ABSTRACT
This study was aimed to analyze the cold and heat nature of Chinese herbal medicine as well as its relation with the major constituent part in order to illustrate the scientific connotation of the cold and heat nature of Chinese herbal medicine from the level of material basis.There were a total of 334 kinds of Chinese herbal medicine with 280 effective ingredients recorded in the first volume of the Chinese Pharmacopoeia.The molecular descriptors of each ingredient (including one-dimensional,two-dimensional,three-dimensional,and semi-empirical calculated molecular descriptors) were calculated.The generalized rule induction (GRI) algorithm was used to mine molecular descriptors with strong correlation to the cold or heat nature of the screened Chinese herbal medicine.The results showed that molecular descriptors of molecular energy state of main components had close relationship with the nature properties of herbs.Compounds with high-energy condition were most from herbs with heat nature;while compounds with low-energy condition were most from herbs with cold nature.In addition to the energy condition of the molecule,topological molecular water partition coefficient,lipid drug property but also the main component of the polar surface area,carbon,hydrogen,oxygen atoms,the number of hydrogen bond donors and other molecular structure descriptors had certain association relationships.It was concluded that the nature of Chinese herbal medicine had certain association relationships with its main ingredients.Among them,the most important molecular descriptors of molecular energy are three-dimensional molecular descriptors.It suggested that the comprehensive effect of Chinese herbal medicine may be relevant to the energy condition of the molecule in main active components of Chinese herbal medicine and the effect on the energy metabolism of the body.
ABSTRACT
Marine traditional Chinese medicine (MTCM) is an important part of Chinese medicine (CM),there are some differences in understanding of the current literature and the extension of the connotation of marine medicine,which leads to the definition dispute of MTCM,hindering clinical application and further development of MTCM.In this study,we explored the concept of MTCM in literature,discussed the attributes of ocean marine CM,summed up the differences between the land CM and MTCM over variety characteristics,effect of drug composition characteristics and biological activity characteristics,and discussed the connotation and extension of MTCM from three aspects of theoretical basis and the effect and source of the drug,leading to the formation of the narrow and broad concept of MTCM.The five kinds of disputes in the definition of MTCM were discriminated according to the concept and connotation,which provided a theoretical basis for the definition and the research of MTCM.Moreover,we also defined the English translation and its abbreviation as Marine Traditional Chinese Medicine (MTCM).
ABSTRACT
Marine Chinese Medicine (MCM) is one of the important part of the traditional Chinese medicine.The exploration of marine organism resources provide a good base for the development of MCM.However,the evaluation for the nature of the new source of MCM becomes one of the key problem of the clinic application of MCM.In this study,613 MCM and their related 1 091 species of marine organisms were screened.Association Rules Mining method and Phylogenetic Tree constructing method were used to find out the association relationship and the distribution regularity of the MCM with different nature in the Phylogenetic Tree.The results showed high collection of the MCM with the same nature on the tree.The MCM from the organisms in the same family might have the same nature.And the association rules for the same nature assembled at the same branch or near branch of the tree.For example,the marine plantae,Chlorophyta,Florideophyceae,and Phaeohpyceae,were related with cold nature,while the marine animalia,including Decapoda,Malacostraca,and Arthropoda,had close relationship with hot nature.Moreover,the neutral nature was related with Squamata.These results implied that there were close relationship between the nature and the affinity relationship.The MCM from the same or close families may have the same or likely nature.This study provided a new index and reference for prediction and evaluation of the nature of new MCM.
ABSTRACT
This study was aimed to analyze the research status of marine medicine in China. The research hot issues and feature rules were summarized in order to discuss development trends for the clinic application and further development of marine medicine in recent 20 years. The CNKI library was used as a source to retrieve literatures on marine medicine. The bibliometric methods and Cytoscape 3.1.1 were used to analyze. The results showed that 582 papers were included. A total of 260 papers were published during 2010 to 2014. And 52 papers were published annually. 266 papers in this field were funded. The papers were mostly published in theChinese Journal of Marine Drugs. A total of 278 research institutes were engaged in the research. And the institute published the most paper was the Ocean University of China. There were 12 researchers who had published more than 5 articles. This study focused on the keywords with highly frequency, which were marine drugs, chemical composition, marine natural products, fingerprints and antitumor. It was concluded that marine medicine had become hot issues. The core of the group has been formed. However, most researches had focused on natural products and pharmacological aspects. Traditional Chinese medicine (TCM) theory had not been taken seriously and the infrastructure was weak, which obstructed the clinical application of marine medicine. We should expand the discovery and study of knowledge on ancient herbal literature as well as clinic application of marine medicine in order to build the knowledge database of marine medicine and experience mode of clinic application.
ABSTRACT
Marine medicine is an important part of Chinese medicine and a growth point of marine economy development.Exploration on the exact weight ratios and curative effect to expand marine medicine clinical application is a significant issue in marine medicine research at this stage. This paper presented a research supposition of“documents retrieval, extraction of marine medicine cases, establishment of case database, statistic analysis, data mining, herb pair Game Theory model establishment, herb pair usage under fixed dosage and matching, in order to explore a new idea of researching marine medicine combined with Game Theory. Through the literature retrieval and text extraction, 458 cases with the herb pair ofLong-Gu (LG) andMu-Li(ML) were received to establish the partnership game model. The iterative removals of strictly dominated strategies were adopted. Assuming that LG and ML used with an equal amount of 30 g was the best response, which reached the Nash equilibrium. The results suggested that dosages of LG and ML used equally at the amount of 30 g, 25 g, 24 g, 20 g, 18 g, 15 g were rationalizable strategies. Frequencies of using an equal amount of 30 g LG and ML was the most of mathematical statistics. LG and ML of 30 g were used equivalently to treat symptoms such as insomnia, inappetence, chills, tinnitus, physically and mentally fatigued, spontaneous sweating and night sweating, and so on with the effect of tranquilizing and constricting. The results can be validated and complemented among association rules analysis, mathematical statistics and game model. It implied that it was feasible to apply mathematical statistics and data mining in combination with Game Theory to study the marine medicine herb pair.

ABSTRACT
Objective To study the compatibility of TCM prescriptions of TCM practitioners of all dynasties of Alzheimer disease (AD). Methods Amnesia, forgetting, dementia, and idiot were set as search words to retrieve relevant literature in Encyclopadia of Traditional Chinese Medicine. Prescription information was screened and standardized to build database. Frequency analysis and association rules were used to mine TCM prescriptions and compatibility rules. Results Totally 449 AD related prescriptions were selected, involving 682 Chinese medicinal herbs. The individual herb with the highest frequency was Ginseng Radix Rhizoma (192);the herbal pair with the highest frequency was Ginseng Radix Rhizoma-Polyhalae Radix (182);the herbal combination with 3 Chinese medicinal herbs with the highest frequency was Poria with Hostwood-Ginseng Radix Rhizoma-Polyhalae Radix (79);the herbal combination with 4 Chinese medicinal herbs with the highest frequency was Polyhalae Radix-Ginseng Radix Rhizoma-Poria with Hostwood-Glycyrrhizae Radix et Rhizoma (37). The results of association rules showed that Ginseng Radix Rhizoma-Polyhalae Radix, Ginseng Radix Rhizoma-Glycyrrhizae Radix et Rhizoma, and Ginseng Radix Rhizoma-Poria with Hostwood were commonly used compatibilities in AD related prescriptions. Conclusion Treatment of TCM practitioners in all dynasties for AD mainly chooses Chinese medicinal herbs with the efficacy of tonifying qi and soothing nerves. The compatibilities and combinations are reasonable and with certain representativeness.
ABSTRACT
Experience mode of marine medicine (EMMM) is the summary of experiences on marine medicine con-cluded by ancient doctors for thousands of years. The mining of EMMM is very important for the clinic application and development of marine medicine. However, these experiences are very difficult to discover for they are all scat-tered in the large number of ancient documents. We proposed that the EMMM can be built by the procedure of in-formation of ancient documents, text-mining of ancient documents, and associate network of informatics unit of ma-rine medicine by non-interactive literature-based knowledge discovery methods, and expert evaluation at the end, so as to provide database for the clinic application and further development of marine medicine.
ABSTRACT
Marine medicine is an important part of Chinese medicine and a growth point of the development of marine economy. Current researches of marine medicine had ignored accumulated experience in clinical medicine for thousands of years of development of marine medicine and the guidance of traditional Chinese medicine (TCM) theory. In this article, we proposed a research mode of Mining experience-Clinical validation-Targets screening-Component screening-Component compatibility-Mechanism study under the guidance of the hypothesis of Nature-Effect-Material Trialism to study marine medicine. Kun Hai Jiang Xin (KHJX) Decoction is a marine formula drawn from the experience of ancient physicians by data mining techniques. Clinical study found that KHJX Decoction can significantly improve the overall clinical efficacy of chronic bronchitis with good clinical safety. Under the guidance of TCM herbal theory, object presented here is based on the work of KHJX Decoctionmining experience - clinical validation. The molecular docking method and receptor-ligand binding assay were applied to screen effective components from herbs of KHJX Decoction and the compatibility plan of effective components under the guidance of the principle of cold and heat effects compatibility. This study is of great significance to clarify the material basis and molecular mechanism of KHJX Decoction in the treatment of chronic bronchitis. It provides a new research mode for marine drug research.
