ABSTRACT
Under the guidance of the theory of traditional Chinese medicine （TCM）， charcoal drugs are widely used in clinical treatment of various bleeding syndromes， in addition， they also have the effect in anti-diarrhea and anti-ulcer， but charcoal drugs are especially effective in stopping bleeding. According to the changes in the properties after processing， the hemostatic effect of charcoal drugs can be roughly divided into two categories. One is not used for hemostasis itself， but used for hemostasis after processing. The other is used for hemostasis itself， and the drug properties are changed or the hemostatic ability is enhanced after processing. By summarizing researches on historical evolution， processing mechanism and pharmacological effects of the commonly used hemostatic charcoal drugs， the author found that preservation or increase of active substances after processing was closely related to the hemostatic effect of charcoal drugs. The hemostatic mechanism mainly involves the influence of coagulation system and platelet function， etc. At the same time， combined with the theory of Qi chromatograph of TCM supramolecular， this paper puts forward the supramolecular research strategy on hemostatic mechanism of charcoal drugs， in order to provide reference for revealing the scientific connotation of charcoal drugs for hemostasis.
ABSTRACT
Objective:To construct the targeting evaluation method of traditional Chinese medicine （TCM） preparations based on supramolecular Qi chromatography theory， and to study the liver targeting effect of Bupleuri Radix on Pien Tze Huang. Method:The molecular connectivity index （MCI） was used to analyze the characteristics of imprinted template and liver targeting tendency of TCM mainly attributed to liver meridian and components of Pien Tze Huang， and combined with target dynamics and total statistical moment principle， aimed at the independent action characteristics of multi-component imprinted template of TCM， a method for evaluating the targeting of TCM preparations was established. Hepatoma rats in Pien Tze Huang group， Bupleuri Radix<italic> </italic>group， Pien Tze Huang+Bupleuri Radix group and blank group were tested and verified. Result:After the average value of MCI of TCM mainly attributed to liver meridian was deducted， the MCI similarity between Pien Tze Huang group and Bupleuri Radix group was 0.376 8， Pien Tze Huang+Bupleuri Radix group and Bupleuri Radix group was 0.988 2， so it was predicted that Bupleuri Radix could enhance the liver targeting of Pien Tze Huang. A system for evaluating the targeting of TCM compounds was established， including relative total uptake efficiency （RUE<sub>T</sub>）， relative total concentration （RC<sub>T</sub>）， relative imprinted tendency （RIT<sub>T</sub>） and relative imprinted variance （RIV<sub>T</sub>）. The RUE<sub>T</sub> and RC<sub>T</sub> of liver were the highest in all tissues （RUE<sub>T</sub>=1.88>1，RC<sub>T</sub><italic>=</italic>2.30>1）， and the corresponding values of other tissues were all <1， indicating that Pien Tze Huang combined with Bupleuri Radix could increase its distribution in liver and enhance liver targeting. Except for plasma， the RIT<sub>T</sub> and RIV<sub>T</sub> of other tissues fluctuated around 1.0， indicating that targeted modification did not change imprinted tendency of Pien Tze Huang and had no significant effect on the types of components. Conclusion:Under the guidance of supramolecular Qi chromatography theory， a targeting evaluation parameter system can be established to characterize the multi-component imprinted effect of TCM preparations by MCI and total statistical moment parameters， so as to realize the evaluation of targeting of TCM preparations. The addition of Bupleuri Radix can increase the liver targeting of Pien Tze Huang.
ABSTRACT
Based on the universal regularity of the automatic action of supramolecular "imprinted template" previously proposed, this paper further analyzed and summarized the historical evolution and research status of the toxicity of Chinese materia medica, and deeply analyzed the production of toxicity of Chinese materia medica by using the theory of supramolecular chemistry. After entering the human body, the aggregation of supramolecular "imprinted template" of Chinese materia medica can interact with the similar "imprinted template" of the subject supramolecular of human in the human body. In other words, the group of toxic components of Chinese materia medica can be identified with the corresponding hole channels in the body, which is the supramolecular chemical mechanism of the toxicity of Chinese materia medica. The dose-effect problem and detoxification treatment of toxic Chinese materia medica is closely related to the equilibrium constant and concentration. When the concentration of the drug with the same (similar to) imprinted template is the same, the toxicity depends on the equilibrium constant of its interaction with the target. Based on this, research idea of equilibrium constant of toxicity of Chinese materia medica was proposed. The equilibrium constant of supramolecular imprinted behavior can explain the toxicity of Chinese materia medica. By studying the equilibrium constant, the supramolecular interaction of the toxic effect can be revealed and the supramolecular system of Chinese materia medica can be well studied.
ABSTRACT
In this paper, based on the supramolecular "Qi chromatography" of traditional Chinese medicine (TCM), combined with the characteristics of corona virus disease 2019 (COVID-19), the historical origin and characteristics of theoretical research on the treatment of epidemic diseases by TCM were analyzed retrospectively, and the key scientific problems for achieving its modernization were proposed, and the countermeasures were illustrated. In fact, the emergence and development history of TCM epidemic theory is a comprehensive and scientific understanding of biomolecular chemistry for epidemic caused by pathogen. From the exploration of the cause of abnormal Qi to the epidemic pathogenic factor, from the treatment based on syndrome differentiation by six meridians to by the defensive Qi and nutrient blood and the triple energizer, which is gradually close to the modern theoretical system of infectious diseases and immunology, all of which are stamped with brand of TCM supramolecular "Qi chromatography" theory. In the long history of biological evolution in nature, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as epidemic pathogenic factor in TCM, human body and Chinese materia medica are biological supramolecules at a specific stage of evolution in nature, which are controlled by the "imprinting templates" of molecular society in gradual biomolecules, with the unchanged laws of mutual advancement, mutation, suitability and mutual restriction. Based on the analysis of the law of supramolecular action hiding in the prevention and treatment of epidemic diseases dealt with TCM on procession of principle-method-recipe-medicines, this paper discusses the key scientific problems of its modernization and puts forward the solutions. It can not only clarify the scientific principle of the prevention and treatment with TCM, develop the multi-component Chinese medicine, accelerate the control of the epidemic situation, but also promote the solution of original frontier key scientific problems such as the material basis of meridians, viscera and syndromes, and the compatibility law of the TCM prescription, in order to protect the existing medical resources and open up a new situation in the modernization of TCM research.
ABSTRACT
Objective:The molecular connectivity index method and total statistical moment method were used to control the quality of traditional Chinese medicine （TCM）， and the stability and consistency of volatile components of Lonicerae Japonicae Flos and Lonicerae Flos were clarified. Method:Volatile oils in Lonicerae Japonicae Flos and Lonicerae Flos from different producing areas was extracted for GC-MS determination with electron bombardment ion source， ion source temperature of 230 ℃， and detection range of m/z 35-650.

ABSTRACT
Research and development of classical prescription of Chinese medicine has become one of the hot spots in the research of traditional Chinese medicine (TCM), and the successful development of the primary standard is crucial to the application of the classical prescription of Chinese medicine. Primary standard of classical prescription is not only the benchmark to measure the quality of preparation of classical prescription, but also the material basis of whole prescription. The development and quality control mode of single component of western medicine is not suitable for the development of TCM preparation with integral medicinal function. Thus, it is very urgent to develop an exclusive research and development model for TCM. In order to break through the quality control technology of primary standard of classical prescription, and comprehensively and accurately elucidate the transmission rule of the component group value of medicinal materials-decoction pieces-primary standard of classical prescription with the present modern science and technology, the genetic polymorphism of TCM, extraction kinetics, total quantum statistical moment (similarity) method of fingerprint and supramolecular imprinting template were combined and applied to the development of primary standard of classical prescription. In this way, the development and quality control of TCM will be realized in a real sense and the development of classical prescription of Chinese medicine will be accelerated and promoted.
ABSTRACT
Objective:To establish a mathematical model of total statistical moment, information amount and one-time steady-state feeding quantity of HPLC fingerprint of traditional Chinese medicines (TCMs) and their classical prescriptions, and to carry out experimental verification. Method:The total statistical moment principle, Hardy-Weinberg equilibrium principle and one-time steady-state feeding quantity calculation method were used to study the total statistical moment parameters and one-time steady-state feeding quantity of 15 batches of original medicinal materials, decoction pieces and compound preparations of Taohong Siwutang, these original medicinal materials were from three producing areas. Result:In addition to the total first-order moment, RSD of total zero-order moment, total second-order moment, information entropy and information amount of each medicinal material, decoction piece and compound were all greater than 10%. In the case of single original medicinal material, except for Angelicae Sinensis Radix (142.34 kg), the one-time steady-state feeding quantity calculated according to the RSD change of the accumulated information amount of the whole prescription was the largest (59.10 kg), and according to ratio of the whole prescription, one-time steady-state feeding quantity was the largest (958.57 kg). In the case of processed products, the one-time steady-state feeding quantity of the whole prescription was the largest (73.18 kg) except for Carthami Flos processed with wine (83.28 kg), while according to the whole prescription, one-time steady-state feeding quantity of each processed products was the same as that of the original medicinal material. The one-time steady-state feeding quantity of the compound consisted of the original medicinal materials or processed products was often higher than that of the single medicinal material. Conclusion:The components of TCM are controlled by genetic polymorphism, the chromatographic characteristics (types of components) of Chinese medicine is similar and the intensity of action (content of components) is different. The stability of total first-order moment and information entropy indicates that the overall chemical structure of TCM multi-component system has a stable imprinting trend. The one-time steady-state feeding quantities of each medicinal material in Taohong Siwutang and this compound are far greater than the prescription amount, which can provide reference for the industrial production.
ABSTRACT
The ancient famous classical formulas were developed based on the characteristics of excellent curative effect, small toxic and side effects, and wide clinical application. Its development will promote the development of traditional Chinese medicine (TCM) with huge social and economic benefits. TCM and TCM compounds are multi-component systems, which are multi-component, multi-target and multi-pathway effect on human body, their curative effect is the result of synergistic effect of multi-component. Because of its characteristics, its mechanism of action is still unclear and quality is difficult to control. Therefore, on the basis of biological properties of the multi-components of TCM, it is the key issue to study the preparation process of the medicinal materials-decoction pieces-preparations and the transferability, stability and homogeneity of the quality attributes. Moreover, the supramolecular theory can explain the basic theory of TCM from the macroscopic and microscopic aspects, the study of ancient famous classical formulas can use the supramolecular theory. Both TCM and human body are giant complex supramolecules, and their components are clustered objects reflecting the characteristics of the original imprinting template with genetic polymorphism. The quality attributes, processing, formulation preparation and quality attribute evaluation of TCM are all affected by supramolecular chemistry, which is finally reflected in the preparation of imprinting template and the transfer law of quality properties. Therefore, the application of supramolecular imprinting template theory to study the biogenetic polymorphism of TCM, processing, formulation preparation and quality attribute evaluation of medicinal materials can improve the availability rate of successful research and development of ancient famous classical formulas.
ABSTRACT
In chicken fibroblast cell (CEF) cultures with antiserum against Newcastle disease virus (NDV) strain TZ060107, the virus was passed serially for 50 passages in 3 independent lineages. HN and F genes were amplified and sequenced every 10 passages. The derived virus A1-50 with most mutations among 3 lineages was further passed for another 50 passages in CEF with or without antiserum against A1-50, each in 3 independent lineages. Sequence comparisons for HN and F genes of 60, 70, 80, 90 and 100 passages indicated that the ratio of nonsynonymous mutations (NS) vs synonymous mutations (S) for HN genes in the lineages passed with antiserum against A1-50 was 5.25, which was obviously higher than 2. 375 of NS/ S in the lineages without the antiserum. The stable NS mutations occurred in the first 50 passages with the antiserum against the original TZ060107 were still maintained and one more new stable NS mutation appeared. For the F gene, 3 new stable NS mutations occurred during the second 50 passages in lineages with antiserum against A1-50 when the original NS mutations obtained in the first 50 passages with antiserum against TZ060107 still existed. Cross hemagglutination inhibition (HI) between original virus and its derivative viruses indicated that the more continuous passages in cell culture with antiserum passed, the bigger difference of antigenicity between the virus and the original virus had.
