ABSTRACT
The pharmacodynamic substance of traditional Chinese medicine (TCM) is an important basis for its mechanism and quality control, and also a key scientific issue for the inheritance and development of TCM. However, the complex characteristics of multi-component, multi-target and integrity of TCM, as well as the limitations of modern scientific research technical methods, have brought great challenges to the research. The interactions between Chinese medicine and intestinal flora provide us with a new idea. Based on the effective role of TCM and the hypothesis of correlation between intestinal flora and disease, the research on the material basis and mechanism of action of TCM based on intestinal metabolomics mostly explored the relationship between microflora and host phenotype, gradually deepening, and finally focused on the relationship between intestinal strains and molecular levels. This paper summarized the research ideas and key technologies of this model, in order to provide reference for the application of this model.
ABSTRACT
Stable isotope tracer metabolomics tracks and analyzes the whole metabolic process of the body through the tracer atoms, which belongs to the frontier technology in the field of biomedicine. This technology is of great significance and value for explaining the pathogenesis of diseases, finding biomarkers of diseases and drug action targets. Taking the mechanism of glucose catabolism disorder in depression as an example, this paper systematically expounds the stable isotope tracer metabolomics technology and its application. The research idea of stable isotope tracer metabolomics based on unmarked metabolomics was put forward, and the research strategy of biological significance interpretation from four dimensions of metabolite isotope abundance, key metabolic enzymes, metabolic flow direction and metabolite flow was given, which broke through the bottleneck of stable isotope tracer metabolomics research technology based on overall animal experiment, and provided scientific basis for the promotion and application of this technology.
ABSTRACT
Alzheimer's disease （AD） is a neurological disease highly related to age， which is the main cause of senile dementia and the most common disease leading to the loss of daily living ability of the elderly. AD brings heavy mental burden and economic pressure to patients， families， and society. Traditional Chinese medicine （TCM） ascribes AD to category of "dementia"， believing that the treatment should start from kidney because kidney deficiency is the root cause. Combined with the physiological and pathological characteristics of liver， this paper proposed that liver-kidney homology was an important idea for the prevention and treatment of AD. The main pathological manifestations of AD were amyloid β-protein （Aβ） deposition and neurofibrillary tangles （NFT）， and the pathogenesis was complex. A growing number of studies showed that immune inflammation played an important role in the pathogenesis of AD. The important target of treating AD was the regulation of neuro-immune inflammation through the nuclear factor kappa B （NF-κB）/NOD-like receptor thermal protein domain associated protein 3 （NLRP3）/Caspase-1/interleukin-1β （IL-1β） signaling pathway. Based on the idea of liver-kidney homology， this paper selected the representative formula Hei Xiaoyaosan to explore its effect on the prevention and treatment of AD and the mechanism from the perspective of regulating NF-κB/NLRP3/Caspase-1/IL-1β signaling pathway and inhibiting neuro-immune inflammation， expecting to further promote the in-depth study on the prevention and treatment of AD， and provide references for the prevention and treatment of AD by TCM.
ABSTRACT
Dry granulation technology is a great innovation in granulation technology,which saves many intermediate links and reduces many intermediate costs. It is closely related to the characteristics of materials,dry granulation equipment and process. Dry granulation technology is a systematic engineering science covering many technical fields. The process of dry granulation involves complex mathematical model mechanisms of temperature field,pressure field and velocity field,closely related to the characteristics of materials and drying equipment. However,due to the late start of research on dry granulation technology of traditional Chinese medicine,basic research is still weak. The research on dry granulation technology has achieved great results in the fields of food,chemical industry,agriculture and forestry,showing great reference significance. The advantage of dry granulation of traditional Chinese medicine is that it can be directly granulated by adding an appropriate amount of auxiliary materials in the extract powder of traditional Chinese medicine,without the need of wetting,mixing,drying and other processes. The process is simple and can effectively guarantee the quality of traditional Chinese medicine. The granules obtained by the dry granulation technique are important intermediates for preparing the solid preparations of traditional Chinese medicines,which would directly affect the subsequent molding process and the quality of the preparation products. Therefore,based on the characteristics of dry granulation method in traditional Chinese medicine and by referring to the advanced research results of dry granulation technology in other fields,we would discuss the research ideas of dry granulation in traditional Chinese medicine in terms of the mechanism of dry granulation equipment,technology,on-line detection technology and mathematical model of dry granulation process,hoping to provide reference for the research of dry granulation method in traditional Chinese medicine.

Study on the pharmacodynamic material basis of Chinese materia medica (CMM) is the key and difficult points of CMM research due to its complicated components and synergistic effect of multiple pathways and multiple targets in pharmacological action. Currently, research ideas and research methods of the pharmacodynamic material basis of CMM are being constantly innovated. In this review, research ideas and progress on screening and identification of pharmacodynamic substance of CMM were summarized. It suggested that the research model of interdisciplinarity, multi-dimensional screening and evaluation should be established, in order to provide references for further and comprehensively revealing the mechanism of action of CMM and the law of compatibility, and establishing quality evaluation system of CMM.
ABSTRACT
The correlation between meridians and viscera is the key content of the meridian theory in acupuncture medicine. This paper introduces the close relationship between the meridians running on the body surface and viscera from ancient lite-rature, modern experimental studies (such as acupoint sensitization, neuro-endocrine-immune networks, etc.), and clinical application in the treatment of various conditions with acupuncture, moxibustion, Guasha (scraping) therapies, etc. We also presented some related research ideas (i.e., taking the clinical treatment as the forerunner, paying more attention to multi-disciplinary integration, combining clinical and basic research together, doing research from tridimensional point of review, and making full use of advanced technology, etc.) in order to provide a possibly favorable help for researchers to further reveal the scientific mechanisms underlying correlation between the meridian and viscera in the future.

It is the key to strengthen the comprehensive quality and improve the ability of innovation. Aiming at the low scientific research results of the academic postgraduate students in this sub-ject and the phenomenon of "heavy clinical, light scientific research" and weak scientific research con-sciousness, the Department of Medical Laboratory of Weifang Medical University relies on the laboratory platform to promote the graduate students to form scientific research thinking and improve scientific research ability by relying on the guidance of the tutors, optimizing the training program and encouraging the graduate students to explore actively, which is helpful for graduate students to develop good scientific research quality and establish correct scientific research concept.
ABSTRACT
The research of effective components of Chinese materia medica (CMM) is one of the key points of modernization of traditional Chinese medicine (TCM), is the core of interpreting overall efficacy and mechanism of TCM, and is the important foundation of realizing the safety, efficacy, and quality control of CMM. Previous studies mostly focused on the binary research mode of "component-effect". However, in this paper, the triarchic theory of "property-effect-component" was proposed and the research strategy and mode of exploring the mechanism, effective components, and quality markers (Q-Marker) of TCM were established based on the basic properties of TCM, basic concepts and terms of TCM theory and also related with the core contents of TCM theory including syndrome differentiation and treatment, rules of treatment, method of treatment, compatibility regularity, and drug property. The Yuanhu Zhitong Dropping Pills (YZDP) were taken as an example for demonstration research and corydaline, tetrahydropalmatine, protopine, imperatorin, and isoimperatorin were determined to be the Q-Marker of YZDP.
