Exploration and practice on construction of Tibetan medicine prescription information database and knowledge discovery / 中国中药杂志

This study aimed to explore the underlying framework and data characteristics of Tibetan prescription information. The information on Tibetan medicine prescriptions was collected based on 11 Tibetan medicine classics, such as Four Medical Canons(Si Bu Yi Dian). The optimal classification method was used to summarize the information structure of Tibetan medicine prescriptions and sort out the key problems and solutions in data collection, standardization, translation, and analysis. A total of 11 316 prescriptions were collected, involving 139 011 entries and 63 567 pieces of efficacy information of drugs in prescriptions. The information on Tibe-tan medicine prescriptions could be summarized into a "seven-in-one" framework of "serial number-source-name-composition-efficacy-appendix-remarks" and 18 expansion layers, which contained all information related to the inheritance, processing, origin, dosage, semantics, etc. of prescriptions. Based on the framework, this study proposed a "historical timeline" method for mining the origin of prescription inheritance, a "one body and five layers" method for formulating prescription drug specifications, a "link-split-link" method for constructing efficacy information, and an advanced algorithm suitable for the research of Tibetan prescription knowledge discovery. Tibetan medicine prescriptions have obvious characteristics and advantages under the guidance of the theories of "three factors", "five sources", and "Ro-nus-zhu-rjes" of Tibetan medicine. Based on the characteristics of Tibetan medicine prescriptions, this study proposed a multi-level and multi-attribute underlying data architecture, providing new methods and models for the construction of Tibetan medicine prescription information database and knowledge discovery and improving the consistency and interoperability of Tibetan medicine prescription information with standards at all levels, which is expected to realize the "ancient and modern connection-cleaning up the source-data sharing", so as to promote the informatization and modernization research path of Tibetan medicine prescriptions.

Generic Association Analysis on "Prescription-Formula-Dosage-Property" of Tibetan Medicine Based on Partial Order Structure and Property Theory / 中国实验方剂学杂志

Objective:In view of the complexity of the "Prescription-Formula-Dosage-Property" relationship of Tibetan medicine and the outstanding common relationship，it is difficult to reveal the hidden and specific rules of clinical medication of Tibetan medicine. Method:Based on the attribute partial order structure and the vector structure model of "Ro-Nus-Zhu-Rjes"（Taste，Post-Digestive Tastes and Potency），clustering analysis and other methods and software，this study analyzed the "Prescription-Formula-Dosage-Property" relationship of 184 commonly used prescriptions in the 1995 edition of the standards issued by the Ministry of Tibetan medicine（SIMTM）. Result:Among them，the analysis of the relationship between prescription and formula found that 11 prescriptions with the largest common attribute，such as Chebulae Fructus and Carthami Flos，were the key components of classification and compatibility，which could effectively classify the 8 kinds of prescriptions for the treatment of lung disease，tripa disease and blood fever. Among them，the san Yin and auxiliary viscera function prescriptions，such as Sanguotang powder and Liuwei Liangyao powder，had the strongest commonality. According to the analysis of relationship between formula and dosage ，the dosage of Chebulae Fructus，Carthami Flos，pomegranate seed，Phyllanthi Fructus was the highest，which suggested that these drugs were often used as primary drugs，while the Liuwei Liangyao powder，such as Amomi Fructus Rotundus and Tsaoko Fructus，had a higher frequency but a lower dose，which mainly played a role in regulating the overall drug property of the prescription and protecting the viscera. The Tibetan medicine-specific drugs including Moschus，Bovis Calculus，and Zhaxun，which were used in a high frequency but very low dose，had the effect of enhancing the drug property and guiding the affected part. According to the analysis of the relationship between dosage and property，there were many prescriptions belonging to cool nature，accounting for 75.6%. It was found that 67 prescriptions did not conform to the efficacy due to their different dosage. Conclusion:There are many common components and common usages in Tibetan medicine prescriptions. If these common associations are not treated，it will lead to the result that all diseases take these common associations as the core，but the hidden key factors cannot be solved. Therefore，it is necessary to pay attention to sensitivity and specificity at the multi-dimensional level of "prescription-formula-dosage-property"，so as to reveal the clinical medication thought of Tibetan medicine more effectively.

Construction of Tibetan Medicine Prescription Database for Treating "Gnyan-rims" and Analysis of Their Medication Law Based on Python Language / 中国实验方剂学杂志

Objective:To construct the database of Tibetan medicine prescriptions for "Gnyan-rims" disease， and to explore the invisible medication law of Tibetan medicine in the treatment of "Gnyan-rims" disease， such as prescription compatibility and combination of drug properties. Method:The prescriptions for treating "Gnyan-rims" were retrieved from four Tibetan medical literatures such as <italic>The Four Medical Tantras</italic>，<italic> Kong-sprul-zin-tig，</italic> <italic>Phyag-rdor-gso-rig-phyogs-bsgrigs</italic> and <italic>Sman-sbyor-lag-len-phyogs-bsgrigs</italic>， and the database was constructed under Python code， and the Apriori algorithm and the vector structure model of taste property flavor transformation were used for analysis. Result:According to the characteristics of Tibetan medicine prescription data， with six fields of prescription name， formula， dosage， efficacy， source and original text as the core， a Tibetan medicine treatment "Gnyan-rims" prescription database with functions of cleaning， searching and exporting was established. A total of 7 602 prescriptions were included in the database， among which 598 prescriptions had therapeutic effects of "Gnyan" and "Rims". The results of compatibility analysis showed that Shexiang， Hezi， Honghua， Mukuer Moyao， Tiebangchui， Tianzhuhuang and Bangga were the most frequently used drugs， while the correlation degrees of Shexiang-Mukuer Moyao， Honghua-Tianzhuhuang， Shexiang-Hezi and Shexiang-Tiebangchui were the strongest， and all the drug composition of Wuwei Shexiang pills appeared in the top ten correlations. According to the property analysis of 40 prescriptions containing high-frequency drugs， 19 prescriptions were found to have excessive bitter taste， followed by 9 prescriptions such as Sanchen powders with excessive sweetish taste， and the ratios of sweetish and bitter tastes in six tastes were >35%. The total of sweetish and bitter prescriptions accounted for 70% of the total prescriptions. Among the three flavors， the bitter flavor was the most abundant. The cool effect， dull effect and heavy effect were prominent among the seventeen effects. Conclusion:The prescription database of Tibetan medicine for "Gnyan-rims" can promote the high-quality development of research on prevention and treatment of plague with ethnic medicine. Tibetan medicine treatment of "Gnyan-rims" focuses on the composition of Wuwei Shexiang pills， with the property combination of "cool-bitter and sweet-bitter flavor-cool， dull and heavy"， which mainly treats diseases such as "heat sharp light-mkhris pa-heat". These studies can provide data basis and theoretical reference for the selection of Tibetan medicine prescription and its composition for treating plague.

Research on Standardization of Tibetan Medicine Names and Their Relationship With Official Drug Standards Based on Text Association / 中国实验方剂学杂志

Objective:To construct the knowledge base of Tibetan medicine prescriptions and explore to standardize the names of Tibetan medicine prescriptions. Method:By using the concept of "man-machine combination"，through the construction of Tibetan medicine terminology glossary （data sources： national drug standards，local drug standards，text classics on Tibetan medicines，etc.），the terminology glossary of Tibetan medicine prescriptions was mined. Upon its combination with expert review，the text association between Tibetan medicine prescriptions and various drug standards and dictionaries was constructed，and the standardization methods and techniques of prescription drug names were explored. Result:In this paper，the Tibetan medicine prescriptions approved for marketing in China were taken as the research object，and various inconveniences caused by the inconsistency between the names of prescriptions and the names of medicinal herbs were revealed. This paper also discussed the design ideas on name standardization of Tibetan medicines from three levels： text association，optimization of evaluation methods，and formation of expert decision-making system. We put forward a five-in-one （screening， evaluation， reviewing， fixing， and renewing） research model of Tibetan medicine name standardization. The construction，functions and advantages of the database and thesaurus of Tibetan medicine prescriptions were described in detail， and in combination with the text notes， association between the standard medicinal materials and the prepared prescriptions was then established. Conclusion:The text association method in this paper can accurately reflect the nonstandard names of Tibetan medicine prescriptions. Combined with expert review，it can be， to a certain extent， extended to the standardization of herb names in prescriptions with large scale of or more complex network structures.

Prescription Regularity of The Four Medical Tantras-Scientific Implications of Ro Nus ZhurJes / 中国实验方剂学杂志

Ro Nus ZhurJes theory is the core content of Tibetan medicine,it can be divided into "taste performance"(Ro Yi Nus Pa) and "essential performance"(Ngo Bovi Nus Pa),and "taste performance" is divided into six tastes,eight properties,three tastes after digestion,seventeen effects and so on."Essential performance" is divided into eight kinds,including odor efficacy,sources efficacy,color efficacy,et al.Form bearing relationships that "taste performance" and "essential performance",the butt welding joins the three-factors and twenty characteristics of disease,it is the theoretical basis of Tibetan medicine from collection and processing,from formula to finished product. It is also the main method for the evaluation of drug performance by Tibetan medicine.Many classic Tibetan medicine prescriptions are compatible under the guidance of Ro Nus ZhurJes.However,at present,the research of Tibetan medicine mainly concentrates on the chemical composition and pharmacological mechanism.It is seldom studied from the Ro Nus ZhurJes theory of Tibetan medicine.It is difficult to find the core rules and effect of Tibetan medicine.Therefore,based on the ancient literature of Tibetan medicine,this paper combs the theory of Tibetan medicine property,explains the six tastes,three tastes after digestion,and seventeen effects of Tibetan medicine function in three-factors,twenty characteristics and other diseases attributes,in order to provide theoretical reference for the study of drug properties of Tibetan medicine.

A New Quantitative Method of Tibetan Medicine Property ——Construction of “Ro Nus ZhurJes” Vector Structural Model / 中国实验方剂学杂志

“Ro Nus ZhurJes” theory is the core content of Tibetan medicine property theory, and also the core compatibility law of Tibetan medicine. It takes six tastes of medicine as the surface medicinal property, three tastes after digestion by "three gastropyretie" as the inner medicinal property, eight properties and seventeen effects as the deep medicinal property, and its essential property is the special medicinal property, forming a multi-level medicinal property theory, but its internal structure still needs to be unified and sorted out, clinical practicability needs to be further improved. In this paper, literature mining, Tibetan medicine theory, vector structural model, K-means clustering analysis, Gephi 0.9.2 visualization and other methods were used to sort out the theory of Tibetan medicinal properties. It was found that the inherent structure of Tibetan medicine properties had the multi-dimensional structural characteristics of "seven medicinal properties+three characteristics", and that the same medicinal properties would overlap, while the opposite medicinal properties would offset and could be expressed by vectors. Therefore, the vector structural model of "Ro Nus ZhurJes" of Tibetan medicine was proposed in this paper. Taking twenty-five-flavor Yuganzi powder(skyu-ru-nyer-lnga) and 92 commonly used Tibetan medicine prescriptions as examples, the rates of single prescription with seventeen effects and multiple prescriptions acting on three factors were analyzed. The model analysis results were highly consistent with the clinical efficacy, and the main diseases were the same, which showed that this model had a high degree of fitting and interpretation. It could effectively and intuitively quantify the properties of Tibetan medicine prescriptions and uncover the complex hidden knowledge of Tibetan medicine theory. In the future, the vector structural model of "Ro Nus ZhurJes" will be applied to analyze the classical prescriptions of Tibetan medicine, and the fitting evaluation and modification optimization will be carried out continuously in order to improve the practicability of theory of Tibetan medicine property in the big data environment and provide methodological reference for the quantification of medicinal property of Tibetan medicine prescriptions.

Construction of Prescription Database of The Four Medical Tantras and Analysis of Its Medication Rules Based on Complex Network Analysis and Visual FoxPro / 中国实验方剂学杂志

Objective: The Four Medical Tantras is a classic work of Tibetan medicine, in which drug treatment is one of the four main treatment methods, and prescriptions are the main form of clinical drug use. The study on the medication rules of The Four Medical Tantras has positive significance for the clinical medication research of Tibetan medicine. Method: Prescriptions recorded in Secret Medical Code and Follow-up Medical Code from The Four Medical Tantras were collected, the prescription database was constructed by Visual FoxPro 9.0, combined the dual perspectives of the " fifteen categories" (skabs bco lnga) of Tibetan medical diseases and the " eighteen practices" (lag len bco brgyad) of treatment, and Gephi 0.9.2 complex network was used to analyze its medication rules. Result: The Four Medical Tantras contained 2 695 Tibetan medicine prescriptions, average number of drugs in each prescription was 6.6, prescription composed of ≤ 7 drugs accounted for 69.2%of the total prescription. There were 1 002 kinds of medicines involved in the total prescription, of which 156 was the nodal degrees of Chebulae Fructus, Bambusae Concretio Silicea, Carthami Flos, Piperis Longi Fructus and Zingiberis Rhizoma and so on; followed by 91 nodal degrees of butter (mar), sugar, barley sweetener (sbang ma), honey and brown sugar and so on, which were Tibetan medicinal and edible medicines. According to the classification of diseases in the fifteen categories, there were 495 prescriptions for traumatology (mtshon rma), 323 for fever (tsha ba), 278 for toxics and 197 for three factors diseases. According to the treatment method of eighteen practices, 162 powder, 77 decoction, 84 laxative (bxhal) and others were used. Association rule analysis found that edge weights of Borneolum Syntheticum, Bambusae Concretio Silicea, Carthami Flos, Santali Albi Lignum and other cold medicines were 59, edge weights of pomegranate seeds, Piperis Longi Fructus, Cinnamomi Cortex, Amomi Fructus Rotundus and other warm medicines were 45. Conclusion: The Four Medical Tantras has some characteristics, including the medication rules of elliptic philosophy with cool-warm medicinal properties as the dual core, elimination-diarrhea (zhi-sbyong) as medication methods, weight of rlung-mkhris pa-bad kan as medication dialectical thinking and so on. Among them, the clinical application of butter, barley sweetener, sugar and other special delivery agents of Tibetan medicine is prominent. The prominent clinical application of special Tibetan medicines embodies the philosophy of Tibetan culture with the emphasis on overall balance. It has the multi-dimensional medication rule of " diet plus medicine, medicine plus therapy", and has positive significance for revealing the research on medication rules of Tibetan medicine.

Study on regularity of Tibetan medicine in treatment of gZav-Grib disease (apoplexy sequelae) based on HIS clinical medical records / 中国中药杂志

This research is launched to look for the medication rules and characteristics of Tibetan medicine in the treatment of gZav-Grib( apoplexy sequelae). HIS records of gZav-Grib patients were selected from the Tibetan Hospital of Tibet Autonomous Region and Tibetan Hospital of the city of Naqu. SPSS Modeler,Gephi and other data mining and visualization software were used to study the actual law of drug use in the treatment of gZav-Grib in Tibetan medicine. Finally,479 cases of gZav-Grib patients in Tibetan medicine were included. Their average age is 63 and average hospital stay was 32 days. In total,82 Tibetan medicine prescriptions were used for treating gZav-Grib. The frequency in the front is Twenty-flavor Chenxiang Pills( 338 times),Ruyi Zhenbao Pills( 322 times),and Seventy-flavor Zhenzhu Pills( 315 times). According to the regularity of Tebitan medicine,they were applied in different time periods including the early morning,morning,noon,and evening,for example,in the early morning: Seventy-flavor Zhenzhu Pills,morning: Ruyi Zhenbao Pills,noon: Eighteen-flavor Dujuan Pills,evening: Twenty-flavor Chenxiang Pills. In the clinical joint,18 groups were found in the 10% support and 70% confidence. There are two prescriptions confidence more than 80% which nature focus on Gan,Ruan,Xi,Liang,Dun,Han,Wen. gZav-Grib of Tibetan medicine can be divided into two types: r Lung-Grib type and k Hrag-Grib type,in which the medicine of r Lung-Grib type takes Seventy-flavor Zhenzhu Pills as the core prescription,while the medicine of k Hrag-Grib type takes Ruyi Zhenbao Pills as the core prescription. It is found that the treatment of gZav-Grib by Tibetan medicine is mainly dominated by the treatment idea about " Therapeutic r Lung and blood,Consideration of venous diseases". Treatment functions is promoting the circulation of Qi,clearing blood heat and getting rid of bad blood,achieving the purpose of treating both principal secondary aspect of gZav-Grib. The research methods based on the HIS can't only optimize the Tibetan treating gZav-Grib sequela treatment plan and rule of medication,but also provide the scientific basis for Tibetan medicine treat gZav-Grib.

Study on regularity of drug use in Tibetan medicine treating hypertension based on multi-center clinical medical records and "prescription-property-efficacy-disease" / 中国中药杂志

This study aimed to explore the rule of Tibetan medicine in clinical treatment of hypertension( k Hrag-rLung-stod-vtshangs) and analyze the characteristics of its prescriptions. One hundred and thirty-seven cases of hypertension treated Tibetan medicine were collected. Data mining,Gephi,Cytoscape and other methods and software were used to analyze the characteristics of Tibetan medicine. The results showed that there were 44 cases of r Lung-type hypertension in clinical medical records,while 57 cases of k Hrag-type hypertension. There were 103 treatment prescriptions. The frequency of these prescriptions covered Twenty-five Yuganzi Pills( 96 times),Seventy Pearl Pills( 80 times),Eight Chenxiang Pills( 75 times),and Sanwei Ganlu Powder( 62 times),and they were highly correlated,with confidence greater than 95%. There were 332 prescriptions involved in the prescriptions which is core prescription medicines. This study first proposed the dosage analysis method of Tibetan medicine prescription medicines,and obtained the more dosage of Chebulae Fructus,Phyllanthi Fructus,Aucklandiae Radix,Aquilariae Lignum Resinatum and so on. The correlation analysis of the prescription medicines found that Carthami Flos,Myristicae Semen,Bambusae Concretio Silicea,Caryophylli Flos,Amomi Fructus Rotundus led by Tsaoko Fructus had a high correlation and a confidence greater than 75%. These herbs were guaranteed when Tibetan medicine was used in combination. The key drugs for protecting viscera and regulating the three gastric fires. The prescription is mainly cold,blunt,sparse and rough. Its efficacy focuses on the pathogenesis of blood fever,blood stickiness and venous blockage caused by heat,sharpness,odor and stickiness. It mainly treats Tibetan medicine diseases such as k Hrag-r Lung-stod-vtshangs and k Hrag-vpel( polyemia). It is suggested that Tibetan medicine has a three-in-one invisible treatment principle of " clearing blood-heat,opening vessel and regulating stomach-fire" in the treatment of hypertension,which attributed to both cardiovascular function and gastrointestinal metabolic function. This may be a significant and invisible knowledge of Tibetan medicine in the treatment of hypertension.

Analysis on medication regularity and action mechanism of Tibetan medicine in treatment of spleen and stomach diseases based on data mining and integrated pharmacology / 中国中药杂志

To explore the medication regularity of Tibetan medicine in the treatment of spleen and stomach diseases, analyze the potential drug targets and interactions of the prescriptions, and reveal the mechanism of Tibetan medicine in the treatment of spleen and stomach diseases. The prescriptions in Tibetan medicine for treatment of spleen and stomach diseases were collected, and Traditional Chinese Medicine Inheritance Support System (TCMISS) was used to analyze the association rules between the herbs and discover the core herbs and new prescriptions. The integrated pharmacology platform V1.0 software was used to construct "herb-compound-target" network and investigate the interactions between various herbs and related pathways of Tibetan medicine Wuwei Shiliu powder in the treatment of spleen and stomach diseases. Among the 216 prescriptions of Tibetan medicine in the treatment of spleen and stomach diseases, pomegranate seed was used at a highest frequency (118 times), followed by white cardamom (107 times) and comatose (107 times). 12 new prescriptions were evolved by using the association rules (support>=34%, confidence>=0.85). 5 242 related drug targets and 20 related pathways were obtained from classic formula Wuwei Shiliu Powder (FDR<0.01). It was proposed that Tibetan medicine treatment for spleen and stomach diseases was mainly based on proliferation of "stomach fire" and the main drugs were for regulating Qi-flowing for strengthening spleen. The mechanism may be associated with regulation of digestive juice secretion, proton pump, mitochondria, regulation of intestinal digestion and immunity, the body's immunity to microorganisms function and other multiple targets and pathways to achieve the joint intervention.
