ABSTRACT

OBJECTIVE@#To investigate relationship between cold pain of knee joint and subchondral bone marrow edema (BME).@*METHODS@#From May 2018 to August 2019, 92 patients with knee osteoarthritis (KOA) associated with cold pain of knee were admitted, all patients were underwent MRI examination. The patients were divided into observation group (47 patients with BME) and control group(45 patients without BME). In observation group, there were 6 males and 41 females aged from 36 to 87 years old with an average of (63.2±12.3) years old. In control group, there were 10 males and 35 females, aged from 48 to 84 years old with an average of (62.7±8.3) years old. All patientswere treated with drugs. The degree of joint degeneration was evaluated by Kellgren-Lawrence (K-L) grading. Degree of cold pain of knee was evaluated by knee cold pain score, and degree of BME was evaluated according to WORMS. The correlation between cold pain of knee and K-L grading and BME was analyzed.@*RESULTS@#Score of cold pain in observation group (15.55±7.68) was higher than that of control group (9.42± 5.50), which had significant difference (@*CONCLUSION@#The cold pain of KOA patients is not related to K-L grading, but corelate with BME grading. The Cold pain of knee was more pronounced in KOA patients with BME, and the severity of BME is often related to degree of cold pain. It seemed to be a tendency:the more serious BME, the heavier coldpain.

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

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.

ABSTRACT

Chinese material medica (CMM) is the foundation for treating disease using traditional Chinese medicine (TCM), which is not only guided by the basic theory of TCM but also follows the general rules of drug action. There are both toxicity and efficacy in TCM. For TCM the integrated regularities of its toxicity and efficacy were demonstrated in their prescription, which were qualitatively characterized by compatible experiences such as "seven emotions", "Yin" and "Yang" compatibility, etc. When the toxicity is still produced by oral administration according to the prescription of TCM theory or administration is not abided by original requirement, the integral regularities of toxicity and efficacy that depends on experience appears to be at a loss what to do. Especially in recent years, with the modernization of TCM and the continuous advantages in new medicinal innovation, the CMM safety incidents occurred frequently. It is very urgent for us how to establish a set of integrated methods that are adequately situated to multiple components for TCM. With the combination of the biological supramolecular chemistry and the basic theory of TCM, an integrated model of toxicity and efficacy based on TCM supramolecular "imprinting template" has begun to take shape. The CMM and the human body are both biological supramolecular bodies that follow the autonomic action rules of their "imprinting template". The integrated trends of toxicity and efficacy are able to build on systematical results of single components in CMM based on the theory of TCM to treat diseases by prescription on syndromes. It is also the systematic actions resulting from single effective components in CMM by the supramolecular "imprinting template" self-acted regularities. Through the qualitative and quantitative analysis of supramolecular "imprinting templates" characteristics and actions and their network chromatotoxicometrology (chromatopharmacometrology), a toxic and effective integrated analysis methods will be established on an integrated "therapeutic window" for components in the CMM. This effort will finally permit the description of the components of the pharmacokinetic overlaid law of "therapeutic window", plotted to lower-overflow, entering and higher-overflow profiles.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

The paper aims to elucidate and establish a new mathematic model: the total quantum statistical moment standard similarity (TQSMSS) on the base of the original total quantum statistical moment model and to illustrate the application of the model to medical theoretical research. The model was established combined with the statistical moment principle and the normal distribution probability density function properties, then validated and illustrated by the pharmacokinetics of three ingredients in Buyanghuanwu decoction and of three data analytical method for them, and by analysis of chromatographic fingerprint for various extracts with different solubility parameter solvents dissolving the Buyanghanwu-decoction extract. The established model consists of four mainly parameters: (1) total quantum statistical moment similarity as ST, an overlapped area by two normal distribution probability density curves in conversion of the two TQSM parameters; (2) total variability as DT, a confidence limit of standard normal accumulation probability which is equal to the absolute difference value between the two normal accumulation probabilities within integration of their curve nodical; (3) total variable probability as 1-Ss, standard normal distribution probability within interval of D(T); (4) total variable probability (1-beta)alpha and (5) stable confident probability beta(1-alpha): the correct probability to make positive and negative conclusions under confident coefficient alpha. With the model, we had analyzed the TQSMS similarities of pharmacokinetics of three ingredients in Buyanghuanwu decoction and of three data analytical methods for them were at range of 0.3852-0.9875 that illuminated different pharmacokinetic behaviors of each other; and the TQSMS similarities (ST) of chromatographic fingerprint for various extracts with different solubility parameter solvents dissolving Buyanghuanwu-decoction-extract were at range of 0.6842-0.999 2 that showed different constituents with various solvent extracts. The TQSMSS can characterize the sample similarity, by which we can quantitate the correct probability with the test of power under to make positive and negative conclusions no matter the samples come from same population under confident coefficient a or not, by which we can realize an analysis at both macroscopic and microcosmic levels, as an important similar analytical method for medical theoretical research.

ABSTRACT

Injections for traditional Chinese medicine have over 60 years of history of development and application. In recent years, however, their adverse reactions have been reported one after another. Consequently, studies on screening sensitinogens (sensibiligens) from injections for traditional Chinese medicine have drawn people's attention and become a tough problem all over the world. This essay analyzes the current state of studies on screening techniques of sensitinogens in injections for traditional Chinese medicine according their mechanism of immunotoxicity, and then proposes to adopt the synthetic immunoassay combining immunity bottle chip, immunity cover chip and immunity chromatographic fingerprint to screen sensitinogens from injections for traditional Chinese medicine, in order to build a safety evaluation barrier for development and clinical application of injections for traditional Chinese medicine.

ABSTRACT

The qualitative and quantitative analysis on traditional Chinese medicine and formula components can be made by chemical and instrumental analysis methods. Of both, the instrumental analysis methods play a dominant role, including HPLC, HPLC-MS, HPLC-NMR, GC, GC-MS, biochemical and biological effect. But because traditional Chinese medicines and formula have complicated components, chemical methods are so unspecific that they shall be used less or with caution. While instrumental analysis methods are so specific that they are appropriate for analyzing complicated single component. The analysis techniques for multiple components of traditional Chinese medicines and formula focus on fingerprints, but all of these analysis techniques are limited by the pre-requisite of separation and the lack of general-purpose detectors and therefore being hard to realize the determination of all components of traditional Chinese medicines and formula. In the natural world, however, organisms identify native and alien components through specificity and non-specificity of clusters decided by antigens and antibodies. For example, components of traditional Chinese medicines are directly or indirectly synthesized into antigens and injected into animals, in order to generate specific antibodies and then collect cross reaction information of these components to specific antibodies. As for components without cross reaction, their contents shall be directly read out on the basis of the inhibition rate curve of competitive reaction for specificity of antigens and antibodies. Besides, a cross inhibition rate matrix shall be established first, and them a multiple regression linear equation between cross component concentration or concentration logarithm and inhibition rate by labeling the immunity competitive reaction between antibodies and haptens of traditional Chinese medicine and compound components, and then solved to obtain concentration of each component. The two results are combined to establish the synthetic immunity chip method for traditional Chinese medicine and formula components.

ABSTRACT

A new qualitative and quantitative analytical method of the chromatographic fingerprints: the Total Quantum Statistical Moment (TQSM) has been eluciated and established according to statistical moment principle. The study was carried out with model drugs as the alcohol extracted liquid for Radix et Rhizoma Rhei (AELRR) by HPLC under the chromatographic conditions that the column was C18, 4.6 mm x 250 mm, 5 microm; the detection of wavelengths was set at 254 nm; a solution of acetonitrile: 1% acetic acid water (from 0:100 to 100:0) was carried with gradient elution as the mobile phase; the ratio of flow was 1 mL min(-1); the temperature was 40 degrees C. The coefficients were dealt with Excel document. It has been established the expressions that consists of four main parameters: 1) total quantum zero moment as AUC(T), area under curve; 2) total quantum respondent ratio as AUCPW(T), area under curve per weight; 3) total quantum center moment as MCRT(T), mean chromatographic retention time of total quantum, expressed by lambda(T); 4) total quantum variance as VCRT(T), variance of mean chromatographic retention time of total quantum, expressed by sigma2(T), by which we have obtained. The TQSM's parameters of the AELRR, such as AUC(T) as 3.273 x 10(8) microV s, AUCPW(T) as 2.286 x 10(6) microV s mg (-1), MCRT(T) as 33.50 min, VCRT(T) as 484.4 min2, and total quantum concentration as 143.2 mg mL(-1). The total quantum statistic moment can be characterized the curve of chromatographic fingerprints with expressive parameters above, also used to quantitative analyses by AUC(T), to qualitative analyses by AUCPW(T), MCR(T), and VCRT(T).

ABSTRACT

<p><b>OBJECTIVE</b>To establish the mathematical kinetic model of the components extracted from the FTMC (formulae of the traditional Chinese medicine) and analyze parameters of the astragaloside IV extracted from the BYHWD (Buyang Huanwu decoction).</p><p><b>METHOD</b>The model, including algebra and differential groups, have been set up according to the FICK discipline and Noyes-whitney soluted theories, as well as two transfer diffusive processes ((1) from protoplasate to apoplasmic, also from material compartment interior cell membrane to outside compartment; (2) apoplasmic to solution, also from outside compartment to solvent compartment) on components extraction from the FTMC. The equation groups, according to laplace transform, have been given a expression as solutions, which indicate the quantitative changes of the component concentration in solvent vs. time. The model kinetic parameters have been analyzed, meanwhile the parameters of the astragaloside IV in the BYHWD under 100 degrees C, extracted by water, have been analyzed by way of this model:</p><p><b>RESULT</b>It has been established a mathematical model that consists of three parts of e exponent. The kinetic parameters: M, alpha, N, beta, L, pi, K, k1', k2', rho1, rho2, tmax, Cmax, AUC, w0, P, D of the BYHWD were respectivelly 0.061 27% , 0.280 2 min(-1), - 1.027% , 0.008 965 min(-1), 1.077%, 0.002 665 min(-1), 3.451 x 10(-3) min(-1), 3.188 x 10(-3) min(-1), 0.375 9 min(-1), 1.420 min, 0.754 7 min, 184.9 min, 0. 0572 1 mg x mL(-1), 289.9 min, 0.070 11%, 46.24%, 22. 35%.</p><p><b>CONCLUSION</b>The kinetic model, applied to isolated system, can have been of the rule of multiplex linear. Each parameters can be analyzed completely.</p>
