In this paper, based on the special influence of supramolecular chemistry on the basic theory of Chinese medicines ( CM) , the authors further analyzed the history of meridian tropism and natural origins of CM organisms and explained CM ingredients and the universal regularity of the automatic action of the supramolecular "imprinting templates" hole channel structure. After entering human bodies, CMs, as the aggregation of supramolecular "imprinting templates" , automatically seek supramolecular subjects that are matched with their "imprinting templates" in human meridians and organs for the purpose of self-recognition, self-organization, self-assembly and self-replication, so as to generate specific efficacy in meridians and organs, which is reflected as the meridian tropism phenomena at macro level. This regularity can be studied by in vitro and in vivo experimental studies. In vitro methods are mostly supra molecular structure analysis and kinetic and thermodynamic parameter calculation; Whereas in vivo methods are dominated by the analysis on object component distribution, chromatopharmacodynamic parameters and network chromatopharmacodynamic parameters; Particularly, the acupoint-medicine method can simplify to study the supramolecular subject-object relations. Consequently, CM's'meridian tropism reveals the universal regularity for interactions of macromolecular and micromolecular "imprinting templates" of subjects and objects in natural organisms. As the first barrier for the material base of the CM theory and breakthrough in the modernization of the basic CM theory, meridian tropism plays an important role in studies on basic theories of the basic CM theory.

The paper, based on the previous publication as special impact of Chinese medicine theories on supramolcular chemistry, aims to analyze the natural origination for the Chinese medicine and to explain the special impact of "Qi chromatography" reaction on "imprinting templates" in supramolcular host of human being with Chinese medicine, in order to reveal the CM's properties of "medical element" with "imprinting templates" autonomisation generally took place in natural supramolecules, and also to discover that the CM's pharmacology are satisfied with its own approaches different form western pharmacology. It was decided, for CM's pharmacology guided by CM's theories, to "Qi chromatography" relations between the CM's ingredient groups and the meridian zang-fu viscera. The supramolcular chemistry played an all-through role in procession of making macro-regularities and special presentation on behavior of "Qi chromatography" impulse owning to the matching action of all kinds of ingredients on the meridian zang-fu viscera with similar "imprinting templates". The CM's pharmacology were guided by CM's theories, owing to its interpretation of supramolecular chemistry. The pharmacology was achieved to construct up completely on base of classical chemical single molecular bonds whereas the CM's pharmacology be configured to big building by way of "imprinting templates" as multi-weak bonds among "supramolecular society". CM's pharmacology was supramolcular pharmacology dealt with "molecular society" on the base of western pharmacology, and employed to double research approaches both math-physical quantitative representation on macroscope and qualitative analyses in microscope.

As a therapeutic agent in thrombosis the fibrinolytic enzymes are of interest and the search for a new enzyme continues. A novel fibrinolytic enzyme was produced from Rhizopus chinensis 120, which was screened from the starter for brewing rice wine in the South of China, by solid fermentation, and purified through ammonium sulfate precipitation, hydrophobic interaction, ionic exchange and gel filtration chromatographies. The purified enzyme hydrolyzed fibrin, it cleaved the alpha-, beta- and gamma-chains of fibrinogen simultaneously, and it also activated plasminogen to plasmin. The enzyme hydrolyzed N-Succinyl-Ala-Ala- Pro-Phe-pNA, and Km was 0.23 mmol/L and Kcat 16.36 s(-1). The optimal temperature of the enzyme for hydrolying fibrin was 45 degrees C, and the optimal pH range of 6.8 - 8.8. The isoelectric point of the enzyme estimated by isoelectric focusing electrophoresis was 8.5 +/- 0.1. The enzyme was a glycoprotein. EDTA, PCMB, PMSF inhibited the activety of the enzyme, and SBTI, Lys, TPCK, Aprotinine had none obvious inhibition, which suggested that the activity centre of the enzyme had hydrosulfuryl, metal and serine. The first 12 amino acids of the N-termimal sequence of the enzyme were NH2-Ser-Val-Ser-Glu-Ile-Gln-Leu-Met-His-Asn-Leu-Gly, and had none homology with that of other fibrinolytic enzyme from other microbes. The novel fibrinolytic enzyme from Rhizopus chinensis 12# has potential to become a therapeutic agent in thrombosis.

The paper aimed to elucidate the specific impact of supramolecular chemistry on the Chinese medicine theories (CMT) in their modernization, after had summarized up the research status of supramolecular chemistry and analyzed the possible supramolecular forms of Chinese medicine (CM), as well as considered the problems in modernization of CM theories. On comparison of the classical chemistry that delt with chemical bonds among atoms, the supramolecular chemistry was rather concerned with varietes of weak noncovalent bonds intermolecules, and reflected the macro-apparent chemical properties of each molecules, and was the most appropriate chemical theories to explain the CMT and microcosmic materials. The molecules in the human body and Chinese material medica (CMM) formed supramolecules by way of self-assembly, self-organization, self-recognition and self-replication, with themselves or with complexation, composition, chelation, inclusion, neutralization etc. Meridian and Zang-fu viscera in CMT might be a space channel structure continuously consisted of unique molecules cavity that was imprinted with the supramolecularly template inside and outside of cells, through which the molecules in CMM interacted with the meridian and Zang-fu viscera. When small molecules in human body imprinted with macromolecules in meridian and Zang-fu viscera, in other words, they migrated along within imprinting channels of meridian and Zang-fu viscera on behavior of "Qi chromatography" impulsed by the heart beat, finally showed up on macroscopic the anisotropy of tissue and organ, as described namely as visceral manifestation in Chinese medical science. When small molecules in CMM interacted with imprinting channel on meridian and Zang-fu viscera, the natural properties and efficacy regularities of CMM was reflected on macroscopic. Therefore, the special representation forms of basic CMT is based on the macroscopic expression of "Qi chromatography" abided by imprinting effect regularities, and on whether the imprinted template of small molecules matched with cavity template of macromolecules in meridian and Zang-fu viscera, only is the adequate representation of supramolecular chemistry for them. The CMM materials is the mixture including single molecules and supramolecules. The compatibility for CM prescriptions can significantly change the function rules. Therefore in the study of basic CMT, we should pay special attention to the laws of supramolecular chemistry. It is the most essential differences of the CMT from the modern medicine which established by the laws of single molecular theories.

More and more disputes have happened to confront us continuously since the separation of Japanese(wild) honeysuckle flower in Chinese Pharmacopoeia in 2005. The state pharmacopeia committee decided to separate Japanese(wild) honeysuckle flower into two species for japanese(wild) honeysuckle flower, but didn't define their the convincing reasons still did not provide to us as a result that two medicines are not described the differences in natural properties, efficiency and indication, usage and dosage, as well as not given a resolving methodand specific solution. It was known for us that in the history of traditional Chinese medicine(TCM), the phenomenenphenomena of the "one drug from multi-species" and "one species for multi-drug" are very ordinary thingswere ubiquitous. Whether separation of the drug species are separated shall be decided to by clinical efficiency. Through Chinese pharmacopoeia (2015 edition) issue of Chinese Pharmacopoeia the 2015 issue of the Chinese Pharmacopoeia, we still cannot find a scientific solution for the dispute of for Japanese (wild) honeysuckle flower, perhaps because of insufficient reorganization of TCM clinical medication regularities, such as "treatment of different diseases with same drug", " treatment of the same disease with different drugs" and "treatment of the same syndrome with multi-prescriptions", and "one prescription treating multiple syndromes"; lack of in-depth analysis for multi-component TCM compounds and autonomisation of "supermolecular template" for organs and meridians; less attention to the advance of efficacy and safety evaluation technologies for multi-component TCM compounds; impacts from the medication mode of "one ingredient-one composition-one effect"; as well as insufficient research methods for bioequivalent evaluation in preclinic and clinic studies . The dispute for species combination or separation for Japanese(wild) honeysuckle flower was apparently caused by regional economy, drug biological equivalent of efficacy and safety, but arising from clinical principles for systematical syndrome treatment with TCM, or concepts in the treatment of diseases with TCM or western medicines. This paper focused on current studies on Japanese(wild) honeysuckle flower in the combination with TCM clinical medication regularities, such as "treatment of different diseases with same drug", "treatment of the same disease with different drugs" and "treatment of the same syndrome with multi-prescriptions", and "one prescription treating multiple syndromes", expounded the specific pharmacological regularity of "heterogeneous equivalence" of Japanese (wild) honeysuckle flower, and put forward methods for studying bioequivalence of Japanese(wild) honeysuckle flower, in order to solve the combination and separation of Japanese(wild) honeysuckle flower and lay a foundation for promoting the development of Chinese herbal medicine industry.

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 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.

This paper discussed the processing methods of Pinelliae Rhizoma in the successive dynasties by consulting ancient and modern books, literature and related codes. The processing methods of Pinelliae Rhizoma has experienced various historical periods. Since the processing method of Pinelliae Rhizoma processed by slicing appeared in the Huangdi Neijing, there have been a series of different processing methods and requirements are founded, such as cleansing, cutting, decocting and so on. Among them, the raw Pinelliae Rhizoma, Pinelliae Rhizoma Praeparatum, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, Pinelliae Rhizoma Praeparatum cum Alumine are still in use today and are widely used. However, there are differences in the processing methods, accessories and their dosages of these various processed products in different dynasty. The processing technology and quality standard of Pinelliae Rhizoma need to be further standardization.
