RESUMEN
With human placed in the whole nature, by following the biologic evolution path, the property of channel structure for "imprinting template" in meridian and zang-fu was explored with supramolecular chemistry. In the history of biologic evolution, each molecule in "molecule society" gradually developed into various highly-ordered supramolecular bodies based on self-identification, self-assembly, self-organization, self-replicating of"imprinting template", and thereby the original biochemical system was established, and finally evolved into human. In the forming process of supramolecular bodies, the channel structure of"imprinting template" in guest supramolecular bodies would be kept by host supramolecular bodies, and communicate with the outside to exchange materials, energy, information, otherwise life phenomenon could not continue, for which it was the chemical nature of biolo-gical supramolecular bodies for body to develop meridian. Therefore, the human was a gigantic and complicated supramolecules body in biological nature, and possessed the supramolecules "imprinting template" at each stage of evolution, for which the meridians were formed. When meridians converged, acupoints appeared; when acupointsconverged, zang-fu appeared. With the promotion of the blood from heart, according to"imprinting template", the guest supramolecular bodies and host meridian produced qi-analysis, which was the qi-phenomenon of guest in meridian. It presented as zang-fu image of physiology and pathology as well as action regularities of medication and acupuncture tolerance, by which current various meridian viewpoints could be explained and propose the hypothesis of meridian supramolecular bodies. The meridian and its phenomenon was decide by its "imprinting template" of supramolecular bodies and self-reaction regularities, which abided through the living nature. This was the substance for meridian biology.

To analyze the research status of traditional Chinese medicine (TCM) processing and key scientific issues to be resolved by using characteristic of TCM biological supramolecules and reaction theories of 'Qi chromatography' to human being, and then put forward the solution countermeasures. Based on the previous explications of theories of the Chinese medicine with supramolecular chemistry as 'Qi chromatograpy', biological supramolecular chemistry theory was used to explain the root of the problem in TCM processing and form the countermeasures for supramolecular chemistry research in the processing of TCM decoction pieces. TCM is a huge complex biological supramolecular body, so the processing of TCM is in view of the processing of huge complex biological supramolecular body. In nature, it is a TCM pharmaceutical technology with chemical changes of the subject and object of biological supramolecular body with or without auxiliary materials, under the condition of high temperature and high humidity. Supramolecular chemistry was throughout the processing of TCM, so the use of supramolecular technology was appropriate in research. TCM decoction pieces were the product of subject and object molecular changes after supramolecular chemistry reaction, with changes in physical and chemical properties of the subject and object molecules, such as bound water overflow, chemical bond rupture, dehydration, carbonization, and reaction with auxiliary materials. Changes in drug property and drug efficacy after processing depended on the degree of subject and object "imprinting template" change, which can be measured by 'Qi chromatography' function of supermolecular imprinting template in human body. In this paper, the research ideas, methods, variety attribution, processing principle, quality standard and clinical application were analyzed to find out the sticking point of the problems, and form the countermeasures with supramolecular chemistry as the core. The processing of TCM is a chemical technology of biological supramolecular body based on the function of supermolecular 'imprinting template' (medical element) of human meridian-viscera, and its reaction products (decoction pieces) showed determinacy when used alone and compatibility when used together, which may constitute a compatible drug delivery system of TCM in clinical application.

Controlled sustained-release preparation (CSRP) is a definitely important source of innovative medicines, however, its further researches and development are limited due to the complexity of Chinese medicine (CM) compositions, and a series of unclear key problems like the apparent properties from physical and chemical aspects. Combined with the CM characteristics of the multiple components and synergistic effect, a series of bottleneck problems in the preparation of CSRP were analyzed. Then the mechanism and influences of supermolecular chemical theory in the CSRP about the multiple-components overall-control were explored under the guideline of "overall control, synchronous dissolution" in CSRP, based on the previous explications about supramolecular chemistry theories and with the application of single component precision controlling technologies. The supermolecular mechanism of multi-component overall control and synchronous release of the CSRP was investigated, providing an useful academic reference for the research and development of the CSRP and laying the theoretical and technical foundation for the manufacturing process of CSRP.

To investigate the effect of the ingredient group of traditional Chinese medicine (TCM) with different "imprinted template" on the supramolecular solubilization ability of licorice, in order to lay a theoretical foundation for explaining the solubilization phenomenon of the components of TCM. Based on the independent supramolecular "imprinted template" rules, molecular connectivity index (MCI) and the correlation of n-octanol-water partition coefficient (logP) were used to indicate hydrophilic lipophilic capacity of TCM, and the extractum rate was used to indicate the solubilization effect of licoriceon single TCM herbs or compounds. The solubilization ability of licorice was evaluated based on MCI, logP and the extractum rate. According to the results, the correlation coefficient between MCI and logP for single herbs was 0.942, and that for single herb adding licorice was 0.916. The extractum rate of most herbs was increased after adding licorice. The correlation coefficient among the extractum rate as well as MCI and logP change values before and after adding licorice were respectively 0.837, 0.405. The correlation coefficient between MCI and logP for eight compounds was 0.937. Meanwhile, licorice had a solubilization effect on the remaining 7 compound except for Huangqi decoction. Therefore, licorice shows the solubilization effect through the independent supramolecular "imprinted template", so as to improve the hydrophilic lipophilic ability. There was a high positive correlation between the MCI and logP in ingredients for TCM, which could be used as important parameters to indicate the "imprinted template" feature for components of TCM. The study on the solubilizing effect of TCM with the supramolecular "imprinted template" theory was feasible, and will lay a foundation for the reform of single-herb dosage form.
