Résumé
Exosomes are lipid bilayer membranous vesicles actively secreted by various cells in the organism, which are like nanoparticles and have messenger targeting. Combining with the theory of supramolecular "Qi chromatography" of traditional Chinese medicine (TCM), research ideas and strategies of modernization of TCM can be constructed. Exosomes are secreted by cells, and the membrane contains nucleic acids, proteins, lipids and small molecular metabolites and others, which can accurately coordinate the functions of each cell, concentrate and transmit the functional information of the parent cell, and is the concise form of reflecting cell functions. At the same time, it is loaded with the "imprinted templates" of the supramolecular "Qi chromatography" theory of TCM. If the "imprinted templates" carrying rules among the gene-protein-lipid-small molecules wrapped in it is studied, the modern experimental research ideas and strategies of TCM theory can be established for revealing the functions of the body's meridians and viscera. Firstly, the present situation of exosomes, including discovery, secretion, characteristics, functions, attribution, uptake, research methods and application status, were reviewed in this paper. And the natural properties of its precise messenger targeted delivery vehicle were elaborated, reflecting the operation law of microscopic substances in meridians and viscera. Secondly, to explore it as an important carrier of the concentrated "imprinted templates" of the supramolecular "Qi chromatography" theory of TCM, and integrating the research methods of exosomes and supramolecular chemistry of TCM, this paper proposes experimental research ideas and strategies on the microscopic material basis of meridians and viscera, compatibility of TCM compound, and targeting of TCM targeted preparations.
Résumé
In the era of artificial intelligence based on big data, data acquisition, storage and processing are more convenient, which provides a guarantee for accelerating the development of traditional Chinese medicine (TCM), but it has not yet achieved organic integration with TCM theory. Based on preliminary research on the supramolecular "Qi chromatography" theory of TCM, combined with the current development trend of artificial intelligence, this paper analyzed the biological intelligence attribute of the function of TCM supramolecular "imprinting template", in order to provide reference for the development of TCM drug innovation. Both the human body and Chinese materia medica are giant complex supramolecular bodies evolved from natural organisms. According to the "imprinting template", the "social molecules" are controlled step by step to form the meridians and viscera. The interaction produces the original theory of TCM, in which the self-recognition, self-assembly, self-organization and self-replication of the "imprinting template" reflect the "intelligence" function attributes:the human body uses the "imprinting template" to self-identify and sense the ingredients of TCM, and store the memory information database in the meridian and collateral organs in the form of "imprinting template", and then pass the "imprinting template". The comparison, analysis, and judgment of imprinting templates guide the self-assembly, self-organization and self-replication among "molecular society", synthesize biological machines, produce biological functions, repair or strengthen biological supramolecular bodies, and present the most basic "intelligence" attribute. This suggests that the theory of theory-method-prescription-medicine of TCM is the weak embodiment of biological "intelligence", while the human brain function is the strong embodiment of biological "intelligence". Since the intelligent function of supramolecular "imprinting template" runs through the natural world, artificial intelligence that can characterize the strong "intelligence" form of the human brain will also be integrated into all aspects of the natural world, suggesting the development direction of "intelligence" functionalization of drug innovation mode.
Résumé
The application of modern scientific theories and technologies to explore the mechanism of Chinese medicine and its compounds is one of the key issues in realizing the modernization of traditional Chinese medicine (TCM) research. Chinese medicine and its compounds produce comprehensive pharmacodynamics through multiple components acting on multiple targets, the core of clarifying the mechanism is to solve the key scientific problems of static correlation and dynamic integration verification between the components and the target network topology. At present, the effective method to clarify the mechanism of Chinese medicine and its compounds is to statically correlate the topological network of in vitro components and targets through network pharmacology. Although there are also component-target verification studies, they often learn from research idea of single component-single target, it is urgent to establish a quantitative integration and overall verification method that conforms to the characteristics of TCM. According to supramolecular Qi chromatography theory of TCM, the microscopic mechanism of interaction between Chinese medicine and human body is actually the two supramolecular host and object groups (the active ingredient group of Chinese medicine and the target group of human body) based on imprinted template, which shows the macroscopic properties and pharmacodynamics. Based on this, the author proposes to use supramolecular Qi chromatography theory as the guidance, combined with supramolecular chemistry, network dynamics, quantitative pharmacology and other methods to quantitatively integrate and verify the compositions and the target groups with imprinted template as the core predicted by network pharmacology, looking for the optimal quality markers, greatly reducing the difficulty of multi-component-multi-target experimental verification of Chinese medicine and its compounds.
Résumé
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.
