[Exosome and prevention of Alzheimer's disease: based on theory of kidney storing essence].

The theory of kidney storing essence storage, an important part of the basic theory of traditional Chinese medicine(TCM), comes from the Chapter 9 Discussion on Six-Plus-Six System and the Manifestations of the Viscera in the Plain Questions, which says that "the kidney manages closure and is the root of storage and the house of Jing(Essence)". According to this theory, essence is the fundamental substance of human life activities and it is closely related to the growth and development of the human body. Alzheimer's disease(AD) is one of the common neurodegenerative diseases, with the main pathological features of Aß deposition and Tau phosphorylation, which activate neurotoxic reactions and eventually lead to neuronal dysfunction and cell death, severely impairing the patient's cognitive and memory functions. Although research results have been achieved in the TCM treatment of AD, the complex pathogenesis of AD makes it difficult to develop the drugs capable of curing AD. The stem cell therapy is an important method to promote self-repair and regeneration, and bone marrow mesenchymal stem cells(BMSCs) as adult stem cells have the ability of multi-directional differentiation. By reviewing the relevant literature, this paper discusses the association between BMSCs and the TCM theory of kidney storing essence, and expounds the material basis of this theory from the perspective of molecular biology. Studies have shown that TCM with the effect of tonifying the kidney in the treatment of AD are associated with BMSCs. Exosomes produced by such cells are one of the main substances affecting AD. Exosomes containing nucleic acids, proteins, and lipids can participate in intercellular communication, regulate cell function, and affect AD by reducing Aß deposition, inhibiting Tau protein phosphorylation and neuroinflammation, and promoting neuronal regeneration. Therefore, discussing the prevention and treatment of exosomes and AD based on the theory of kidney storing essence will provide a new research idea for the TCM treatment of AD.

Characteristics and pathogenesis of chemokines in the post-stroke stage.

Chemokines, as small molecular proteins, play a crucial role in the immune and inflammatory responses after stroke. A large amount of evidence showed chemokines and their receptors were increasingly recognized as potential targets for stroke treatment, which were involved in the processing of neovascularization, neurogenesis, and neural network reconstruction. In this review, we summarized the characteristics of chemokine alterations throughout the post-stroke nerve repair phase to gain insight into the pathological mechanisms of chemokines and find effective therapeutic targets for stroke.

Novel antidepressant mechanism of ginsenoside Rg1: Regulating biosynthesis and degradation of connexin43.

ETHNOPHARMACOLOGICAL RELEVANCE: Panax ginseng C. A. Meyer is a valuable medicinal herb and "alternative" remedy for the prevention and treatment of depression. Dysfunction of connexin43 (Cx43)-gap junction in astrocytes is predisposed to the precipitation of depression. Ginsenoside Rg1 (Rg1), the main bioactive constituent extracted from ginseng, is efficacious in the management of depression by upregulating the content of Cx43. Our previous results indicated that pretreatment with Rg1 significantly improved Cx43-gap junction in corticosterone (CORT)-treated astrocytes. However, the antidepressant mechanism underlying how Rg1 upregulates Cx43-gap junction in astrocytes hasn't been proposed. AIM OF THE STUDY: To dissect the mechanisms of Rg1 controlling Cx43 levels in primary astrocytes. METHODS: We examined the changes of the level of Cx43 mRNA, the degradation of Cx43, as well as the ubiquitin-proteasomal and autophagy-lysosomal degradation pathways of Cx43 followed by Rg1 prior to CORT in rat primary astrocytes isolated from prefrontal cortex and hippocampus. Furthermore, the recognized method of scrape loading/dye transfer was performed to detect Cx43-gap junctional function, an essencial indicator of the antidepressant effect. RESULTS: Pretreatment with Rg1 could reverse CORT-induced downregulation of Cx43 biosynthesis, acceleration of Cx43 degradation, and upregulation of two Cx43 degradation pathways in primary astrocytes. CONCLUSION: The findings in the present study provide the first evidence highlighting that Rg1 increases Cx43 protein levels through the upregulation of Cx43 mRNA and downregulation of Cx43 degradation, which may be attributed to the effect of Rg1 on the ubiquitin-proteasomal and autophagy-lysosomal degradation pathways of Cx43.

Muscone derivative ZM-32 inhibits breast tumor angiogenesis by suppressing HuR-mediated VEGF and MMP9 expression.

Inhibition of tumor angiogenesis is a highly effective strategy for cancer treatment. Human antigen R (HuR), an RNA-binding protein, is overexpressed in many cancers and regulates the mRNAs of multiple angiogenic factors by binding to the adenylate-uridylate-rich element in their 3' untranslated region. HuR protein has been demonstrated to be an important regulatory factor in macrophage-mediated angiogenesis, a process in which macrophages are critical for tumor progression. Muscone is a synthetic equivalent of musk, and recent studies have shown that it has a regulatory effect on angiogenesis. In this study, we synthesized five series of muscone derivatives and discovered that compound ZM-32 was effective in preventing HuR RRM1/2-Vegf-a mRNA complex formation. ZM-32 bound to HuR RRM1/2 protein with a KD value of 521.7 nmol/L. Furthermore, ZM-32 inhibited endothelial cell proliferation, migration, and tubule formation, and suppressed the VEGF/VEGFR2/ERK1/2 signaling axis mediated by macrophages in vitro. We also demonstrated that ZM-32 effectively prevented the proliferation and migration of breast cancer cells and inhibited the growth and angiogenesis of MDA-MB-231 xenograft tumors without any obvious toxicity in vivo. Mechanistically, exposure to ZM-32 influenced the mRNA stability of Vegf-a and Mmp9 in a HuR-dependent manner in both macrophages and MDA-MB-231 cells. Thus, in this study we identified a new muscone derivative, ZM-32, with anti-angiogenesis effects mediated via targeting HuR in breast cancer, that may become a potentially valuable lead compound for anti-cancer angiogenesis.

[Research status of common processing technology of traditional Chinese medicine "maintaining medicinal properties after carbonisatus" and supramolecular "imprinting template" characterization technology].

Based on the characteristics of biological supramolecules and the law of " imprinting template",the research status and common problems in " maintaining medicinal properties after carbonisatus" in traditional Chinese medicine( TCM) were analyzed,and the further countermeasures were put forward. According to the historical evolution of " maintaining medicinal properties after carbonisatus" in TCM processing,the origin of its common problems was clarified by using the theory of biosupramolecular chemistry. TCM is a megacomplex biological supramolecular system,so TCM processing is just the processing of megacomplex biological supramolecular system,and its essence is a TCM pharmaceutical technology with chemical changes in host and guest of biological supramolecular system with or without adjuvant material under high temperature and humidity. In this study on pharmaceutical technology,host molecule was destructed in the process of carbonizing,but guest molecule was retained. The changing law of the host and guest molecule was controlled by the " imprinting template",which was reflected in the degree of change in the drug properties and efficacy of the decoction pieces. Supramolecular chemistry ran through the whole process,and the " imprinting template" of charcoal medicine was characterized by the supramolecular topological structure characteristics and imprinting behavior. After being combined with the quantitative mathematical model of heating degree in processing,it can realize the accurate processing of " maintaining medicinal properties after carbonisatus" from the source,quantitatively control the quality of carbonic herbs,and formulate stable and controllable quality standards.

Human replication protein A induces dynamic changes in single-stranded DNA and RNA structures.

Replication protein A (RPA) is the major eukaryotic ssDNA-binding protein and has essential roles in genome maintenance. RPA binds to ssDNA through multiple modes, and recent studies have suggested that the RPA-ssDNA interaction is dynamic. However, how RPA alternates between different binding modes and modifies ssDNA structures in this dynamic interaction remains unknown. Here, we used single-molecule FRET to systematically investigate the interaction between human RPA and ssDNA. We show that RPA can adopt different types of binding complexes with ssDNAs of different lengths, leading to the straightening or bending of the ssDNAs, depending on both the length and structure of the ssDNA substrate and the RPA concentration. Importantly, we noted that some of the complexes are highly dynamic, whereas others appear relatively static. On the basis of the above observations, we propose a model explaining how RPA dynamically engages with ssDNA. Of note, fluorescence anisotropy indicated that RPA can also associate with RNA but with a lower binding affinity than with ssDNA. At the single-molecule level, we observed that RPA is undergoing rapid and repetitive associations with and dissociation from the RNA. This study may provide new insights into the rich dynamics of RPA binding to ssDNA and RNA.

Synthesis of new steroidal quinolines with antitumor properties.

The incorporation of the heterocycles into the steroid nucleus has been recognized as a useful strategy to develop new steroidal agents for disease treatment. Representative examples are abiraterone and galeterone, which are presently used in clinic for the treatment of advanced prostate cancers. Herein we have developed the first Al2O3/KF-promoted pfitzinger reactions for the synthesis of new steroidal quinolines. These new steroidal quinolines showed moderate to good antiproliferative activity against several human lung cancer cells. Of these compounds, compound 2f exhibited the best potency toward the tested three lung cancer cells with IC50 values <10 µM. Mechanistic studies showed that compound 2f concentration-dependently inhibited colony formation, morphological changes, apoptosis, and migration of A549 cells. To conclude, compound 2f could be used as a hit compound for developing steroid-based anti-lung cancer agents.

[Dynamic chromatopharmacokinetics model for components in Chinese medicine and validation in Buyang Huanwu Decoction].

The Chinese medicine is mostly derived from plants or animals, highly polymorphic, with dynamic components which are reflected by the characteristic peaks and fingerprint peaks in chromatographic fingerprints. The chromatopharmacokinetics method for determined components is not applicable due to dynamic changes of chromatopharmacokinetics. Based on the preliminary study, dynamic pharmacokinetics mathematical model for multiple components in Chinese medicine was set up and verified by Buyang Huanwu Decoction as the model drug, applying the principle of the total quantum statistical moment(TQSM), superimposing or subtracting the relevant statistical parameters in blood samples and blank samples. This provided a new method for the chromatopharmacokinetic study of Chinese medicine. HPLC was used to determine the TQSM parameters in blood and blank sample fingerprints of Buyang Huanwu Decoction at each point, and the overall TQSM parameters of drug-containing blood sample and blank samples were obtained with addition calculation of TQSM; while the initial TQSM of the pure drug can be obtained with subtraction calculation. The metabolic and absorption equilibrium constants were calculated iteratively to a steady state using the estimated metabolic equilibrium constants, then the metabolic chromatopharmacokinetic parameters in rats were obtained: VUC_T 1.262×10~8 mAu·s, MRT_T 37.48 h, VRT_T 9.016×10~2 h~2, CL_T 25.79 mL·h~(-1)·kg~(-1), Vs 1.586×10~2 mL·kg~(-1), t_(T,0.5) 6.15 h, respectively. This suggested that 95% of the compounds in whole recipe were metabolized and secreted from the body after 0-96.33 h. The experiment verified that the established mathematical model and the total quantum moment statistics parameters can represent the dose-time relationship of Buyang Huanwu Decoction, which can be used to study on in vivo metabolism dynamics for Chinese medicine.

Construction, expression, and characterization of AG11-843 and AG11-1581.

This data article contains descriptive and experimental data on the construction, expression, and simple characterization of AG11-843 and AG11-1581. AG1 is an important member of the DUF1220 protein family. It׳s hard to get the recombinant protein because of its DNA sequence. The DNA sequence were optimized by proper design, cloned by overlap PCR and constructed into expression vector. AG11-843 and AG11-1581.were over expressed in Escherichia coli, purified and analyzed by dynamic light scattering and gel filtration analysis. An effective technique is provided to construct and express proteins with complicated sequences.

Construction, expression, and characterization of AG11-843 and AG11-1581.

AG1, a member of the DUF1220 protein family, exhibits the most extreme human lineage-specific copy number expansion of any protein-coding sequence in the genome. These variations in copy number have been linked to both brain evolution among primates and brain size in humans. Unfortunately, our current understanding of the structure and function of these proteins is limited because current cloning and expression techniques fail to consistently produce recombinant protein for in vitro studies. The present work describes a method for amino acid and DNA sequence optimization and synthesis, recombinant protein expression and analysis of two AG1 fragments, AG11-843 and AG11-1581. It was first necessary to modify the nucleotide sequence, while holding the GC content at 52.9%. The genes were then sectionally synthesized by overlap PCR. The resulting segments were cloned into the pET-15 b-sumo expression vector and subsequently transformed into BL21 (DE3) cells. After inducing their expression, the AG11-843 and AG11-1581 proteins were isolated and purified. Furthermore, using dynamic light scattering and gel filtration analysis, AG11-843 and AG11-1581 were shown to be present in tetrameric and dimeric forms in solution. To our knowledge, this is the first study to synthesize and express fragments of the DUF1220 protein family for in vitro analysis. Taken together, the proven utility and versatility of this method indicate that it can be used as an effective technique to construct and express other proteins with complicated sequences, thus providing the means to study their function and structure in vitro.

Novel mathematic models for quantitative transitivity of quality-markers in extraction process of the Buyanghuanwu decoction.

BACKGROUND: Nowadays, to research and formulate an efficiency extraction system for Chinese herbal medicine, scientists have always been facing a great challenge for quality management, so that the transitivity of Q-markers in quantitative analysis of TCM was proposed by Prof. Liu recently. In order to improve the quality of extraction from raw medicinal materials for clinical preparations, a series of integrated mathematic models for transitivity of Q-markers in quantitative analysis of TCM were established. Buyanghuanwu decoction (BYHWD) was a commonly TCMs prescription, which was used to prevent and treat the ischemic heart and brain diseases. In this paper, we selected BYHWD as an extraction experimental subject to study the quantitative transitivity of TCM. STUDY DESIGN: Based on theory of Fick's Rule and Noyes-Whitney equation, novel kinetic models were established for extraction of active components. Meanwhile, fitting out kinetic equations of extracted models and then calculating the inherent parameters in material piece and Q-marker quantitative transfer coefficients, which were considered as indexes to evaluate transitivity of Q-markers in quantitative analysis of the extraction process of BYHWD. METHODS: HPLC was applied to screen and analyze the potential Q-markers in the extraction process. Fick's Rule and Noyes-Whitney equation were adopted for mathematically modeling extraction process. Kinetic parameters were fitted and calculated by the Statistical Program for Social Sciences 20.0 software. The transferable efficiency was described and evaluated by potential Q-markers transfer trajectory via transitivity availability AUC, extraction ratio P, and decomposition ratio D respectively. The Q-marker was identified with AUC, P, D. RESULTS: Astragaloside IV, laetrile, paeoniflorin, and ferulic acid were studied as potential Q-markers from BYHWD. The relative technologic parameters were presented by mathematic models, which could adequately illustrate the inherent properties of raw materials preparation and affection of Q-markers transitivity in equilibrium processing. AUC, P, D for potential Q-markers of AST-IV, laetrile, paeoniflorin, and FA were obtained, with the results of 289.9 mAu s, 46.24%, 22.35%; 1730 mAu s, 84.48%, 1.963%; 5600 mAu s, 70.22%, 0.4752%; 7810 mAu s, 24.29%, 4.235%, respectively. CONCLUSION: The results showed that the suitable Q-markers were laetrile and paeoniflorin in our study, which exhibited acceptable traceability and transitivity in the extraction process of TCMs. Therefore, these novel mathematic models might be developed as a new standard to control TCMs quality process from raw medicinal materials to product manufacturing.

Crystal structure and Hirshfeld surface analysis of the anhydrous form of the nucleoside analogue entecavir.

The nucleoside analogue entecavir {systematic name: 2-amino-9-[(1S,3R,4S)-4-hydroxy-3-hydroxymethyl-2-methylenecyclopentyl]-1,9-dihydro-6H-purin-6-one}, C12H15N5O3, is an antihepatitis B virus drug that has been approved in the US, EU and several countries worldwide. We report here the single-crystal structure of the anhydrous form and compare it with that of the previously reported monohydrate form [Jiang & Liu (2009). Acta Cryst. E65, o2232]. Hirshfeld surface analysis has been employed to understand and visualize the subtle packing differences between the two crystalline forms. The results show that, compared to the previously reported hydrated form, the anhydrous crystal has significantly different intermolecular interactions and packing patterns.

Application of TQSM polypharmacokinetics and its similarity approach to ascertain Q-marker by analyses of transitivity in vivo of five candidates in Buyanghuanwu injection.

BACKGROUND: It is well-known that the public still have been facing on a severe issue about the inconsistency of quality and therapeutic efficacy of traditional medicines. Recently, Professor Chang-Xiao Liu has created a new promising concept for identifying relevant quality-markers (Q-marker) from herbs, their formulas and manufacturing products. Therefore, building up a new approach is necessary for us to bridge over quality to efficacy of pharmaceutical products. STUDY DESIGN: In this paper, five candidate Q-markers, astragaloside IV, paeonflorin, amygdalin, tetramethylpyrazine, ferulic acid in Buyanghuanwu injection (BYHWI) had been designed to carry out in rat by using single and polypharmacokinetic models for total quanta to ascertain adequate Q-marker. METHODS: The Q-marker transitivity in vivo was studied with polypharmacokinetic model and its similarity approach, which were modeled with TQSM principle. The Q-marker was ascertained with transitive similarity and bioavailability in polypharmacokinetics. Their concentrations in plasma sample of white rat were determined by RP-HPLC. Data analyses were used by the DAS software for singles and myself-written-program with EXCEL for multiples. RESULTS: In BYHWI, five candidate Q-marker pharmacokinetic profiles were singly fixed to two compartmental models in rat using classical compartmental analysis, but there were tremendous differences among which the candidate parameters were fluctuated from nearly 3552 folds to equivalency. The theoretical value of TQSM polypharmacokinetic parameters such as AUCT, MRTT, VRTT, CLT, VT over the mixure of five drugs were 110.8 ±â€¯51.91 mg min ml-1, 176.0 ±â€¯36.5 min, 39,921 ±â€¯4311 min2, 0.3116 ±â€¯0.02347 ml min-1 kg-1, 54.83 ±â€¯7.683 ml kg-1 respectively. The TQSM polypharmacokinetic parameters in astragaloside Ⅳ ordered by AUCT, MRTT, VRTT, CLT, VT were 110.8 ±â€¯51.91 mg min ml-1, 176.0 ±â€¯36.5 min, 39,921 ±â€¯4311 min2, 0.3116 ±â€¯0.02347 ml min-1 kg-1, 54.83 ±â€¯7.683 ml kg-1, respectively, which were closed to the theoretical values. TQSM similarity versus astragaloside Ⅳ was 0.9661. CONCLUSION: The results represented that the optimum Q-marker in BYHWI is astragaloside Ⅳ, whose transitivity in vivo similarity was close to the behavior of polypharmacokinetics with maximum bioavailability to the total quanta. It is feasible for Q-marker in CMMs to screen on the comparison of single pharmacokinetic behavior and bioavailability to the total quanta.

The Development of Biologically Important Spirooxindoles as New Antimicrobial Agents.

BACKGROUND: Antibiotic resistance is one of the biggest threats to global health today, leading to higher medical costs and increased mortality. Because of the emergence and rapid spread of new resistance mechanisms globally, a growing number of infections are becoming harder to treat as the antibiotics used to treat them become less effective. Therefore, the development of new effective antimicrobial agents is still urgently needed. In last decades, a large number of structurally novel spirooxindoles have been synthesized mainly based on the ylide intermediates generated in situ and further assessed for their antimicrobial activity against different types of bacteria, leading to the discovery of some potent lead compounds with antimicrobial potentials. OBJECTIVE: The aim of this review to submarize recent advances on the synthesis, structure- activity relationship studies (SARs) and antimicrobial activity of spirooxindoles. METHODS: Peer-reviewed research work on spirooxindoles with antimicrobial activity were downloaded from bibliographic databases and analyzed based on their chemoptypes. RESULTS: 50 papers were retrieved from the literature databases, of which 20 papers described the synthesis and antimicrobial activity of spirooxindoles. CONCLUSION: This review highlights the importance of spirooxindoles as potential antimicrobial agents. The antimicrobial activity of spirooxindoles against different types of bacteria is less studied, mainly centering on primary antimicrobial assessment, some of these compounds have showed interesting antimicrobial activity. However, the current study is only limited to primary antimicrobial assessment, no detailed modes of action are investigated.

[Q-marker of Chinese medicine and metabolic regularity of co-network compatibility and rainbow potential].

The effect of Chinese medicine (CM) compound prescription is the combined action results of single herbs based on the basic theory of Chinese medicine, and its function embodies the characteristics of multi components, multi targets and comprehensive effects. It is difficult to study the therapeutic material, establish quality standards or determine Q-marker, so we can't strictly monitor the quality of the whole process of CM. The identification of Q-marker has a profound influence on the whole process of the pharmaceutical engineering of CM. The scattered effect of CM multi-components is regarded as the integral action of the parent nucleus group by the metabolic rule of co-network compatibility and rainbow potential (CCRP). The rule can be used to communicate the individual components and macro components, to reveal the metabolism of CM in organism body and basic law of information exchange, thus revealing the action law of CM on human body. Through the systematic analysis of the Q-marker's guidance to the development of CM and its relationship with the metabolic rule of CCRP, we try to provide some ideas for the identification of Q-marker.

Purification and enzymatic characterization of Gallus gallus BLM helicase.

Mutations in human BLM helicase give rise to the autosomal recessive Bloom syndrome, which shows high predisposition to types of malignant tumours. Though lots of biochemical and structural investigations have shed lights on the helicase core, structural investigations of the whole BLM protein are still limited due to its low stability and production. Here by comparing with the expression systems and functions of other BLM homologues, we developed the heterologous high-level expression and high-yield purification systems for Gallus gallus BLM (gBLM) in Escherichia coli. Subsequent DNA binding and unwinding determinations demonstrated that gBLM was a vigorous atypical DNA structure specific helicase, which not only showed high preference for the 3'-tailed DNA structures but also could efficiently unwind bubble DNA structures with blunt-ends, indicating its biological roles in processing DNA metabolism intermediates. Further comparative analysis between gBLM and gBLM Core revealed that the long N-terminal domain facilitated the binding affinity of forked and bubble DNA structures and it was also required for the DNA unwinding activities of gBLM. Thus, we present the first enzymatic characterization of gBLM and its N-terminal domain, providing a new model for probing the mechanism and structure of human BLM.

Downregulation of MicroRNA-320d predicts poor overall survival and promotes the growth and invasive abilities in glioma.

Previous studies have demonstrated that miRNAs play an important role in tumor development and progression. The role of miR-320d has been studied in several cancers except for glioma. The aim of the study was to investigate the expression levels, biological function, and mechanism of miR-320d in glioma. The expression levels of miR-320d were detected in glioma tissues and cell lines (U87 and U251) by RT-qPCR. Cell proliferation, colony formation, apoptosis, cell cycle, and transwell assays were performed in glioma cell lines transfected with miR-320d mimics or controls to evaluate the effects of miR-320d in vitro. The expression levels of invasive-related proteins were determined by Western blot analysis. Results showed that the expression of miR-320d was significantly decreased in glioma tissues and cell lines. Overexpression of miR-320d could significantly suppress cell growth, migration and invasion, and induced cell apoptosis as well as cell cycle at G0/G1 arrest in U87 and U251 cell lines. Additionally, expression levels of MMP-2, MMP-9, N-cadherin, and integrin-ß1 reduced, while E-cadherin increased in miR-320d mimic group. Overall, this study is the first to demonstrate that miR-320d may serve as an independent prognostic factor, indicating that miR-320d is a biomarker for prognosis and therapy in glioma.

[Impact of ″imprinting templates″ characteristics of traditional Chinese medicine injection supramolecules on (anaphylactoid) hypersensibility].

The (anaphylactoid) hypersensibility mechanism of ″imprinting templates″ characteristics of traditional Chinese medicine (TCM) injection supramolecules was clarified to lay the foundation to build safety evaluation method. Based on the previous publication on special impact of Chinese medicine theories on supramolcular chemistry, combined with the natural origination of (anaphylactoid) hypersensitized special rules as well as the sensitization phenomenon of cordate houttuynia injection, the impact of the structure characteristics of ″imprinting templates″ in TCM injection supramolecules on its (anaphylactoid) hypersensibility was clarified. In Chinese medicine injections, the supramolecular structures can independently be generated, showing overall apparent (anaphylactoid) hypersensibility nature, and their structure characteristics were dependent on the strength. In addition, (anaphylactoid) hypersensitive critical supramolecular structure was present. When it was administrated by ″injection″, it's structure was not easy to be destroyed, often showing apparent immunogenicity, whereas if it was administrated by ″oral″, the structure would be destroyed by the gastrointestinal tract, showing weaker or no apparent immunogenicity. Therefore, there are differences in (anaphylactoid) hypersensibility between ″injection″ and ″oral″ administration of TCM. TCM injections would produce the supramolecules between ″molecular society″ by independent reaction of supramolecular ″imprinting template″ (chemical determinants), showing apparent immune process of recognition, copying, and storage. Single molecule is a special example for this. The screening of anaphylactoid (sensitinogen) includes the single ingredients and their forming supramolecules for TCM injection. This is the unique feature for safety evaluation of Chinese medicine injection.

[Chinese medicine preparation supramolecular imprinting templates based on in vitro release characteristics of BYHW sustained-release tablet].

The study focused on the in vitro release of Buyanghuanwu (BYHW) elementary osmotic pump sustained release tablets. Its band similarity was calculated by the total quantum statistical moment. Meanwhile, in vitro release characteristics were analyzed to discuss the existence of supramolecular imprinting templates. The results show that the same imprint templates may exist in different structures of traditional Chinese medicine(TCM)'s multi-components. The BYHW sustained release tablets prepared by elementary osmotic pump can meet the objectives of "overall control, synchronous release". However, the supramolecular imprinting templates in TCM compound prescriptions should be further explored, the overall and synchronous release of different components was controlled through imprinting templates, so as to seek the more suitable sustained release preparation technology for multiple components of TCM, and make it in line with the characteristics of TCM.

[Dispute for Japanese(wild) honeysuckle flower based on supermolecular imprinting templates].

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.
