The research on biopharmaceutics classification system of Chinese materia medica( CMMBCS) should be finally implemented to the holistic research level of traditional Chinese medicine compounds,while the overall biopharmaceutical properties of traditional Chinese medicine compounds are not only the sum of solubility and permeability of each component. In this study,Gegen Qinlian Tablets was used as the research object,and the contents of 12 representative components,i.e. puerarin,daidzin,baicalin,daidzein,wogonoside,baicalein,wogonin,glycyrrhizic acid,coptisine hydrochloride,epiberberine,berberine hydrochloride and palmatine hydrochloride,were simultaneously determined by HPLC to obtain the mass weight of each component. The in vitro lipopolysaccharide( LPS)-induced RAW264. 7 cells inflammation model was established to investigate the anti-inflammatory effects of 12 representative components and obtain the efficacy weight of each component. In order to obtain the number of doses and effective permeability coefficient which can represent the overall biopharmaceutical properties of Gegen Qinlian Tablets,mass weight was combined with efficacy weight to integrate the solubility and permeability data of each component determined by typical shake flask method and in situ single pass intestinal perfusion model respectively. The results indicated that Gegen Qinlian Tablets should be categorized Ⅳ drug of the CMMBCS with low solubility and low permeability.

Qigui Tongfeng tablet (QLTFT) is a traditional Chinese medicine with good effect for treating gout. Here, network pharmacology method and molecular similarity analysis were utilized to study the effective substance basis and molecular mechanism of the QLTFT on the gout. The similarity to the medicinal compounds is reflected in the Tanimoto coefficient that gives the structural similarity of two compounds. Operationally, similar modifiers were described as pairs of concepts with a similarity score of 0. 500. The results of the molecular similarity analysis suggested that the flavonoids in QLTFT could be new leads for gout. Furthermore, complex biological systems may be represented and analyzed as computable networks. Two important properties of a network were degree and betweenness. Nodes with high degree or high betweenness may play important roles in the overall composition of a network. And the results of network analysis showed that dongbeinine, verticinone-N-oxide, verticine N-oxide, peimine, peiminine, isobaimonidine, dongbeirine, peimisine and simi-arenol which with high degree acted on xanthine dehydrogenase/oxidase, matrix metalloproteinase-9, an arachidonate 5-lipoxygenase-activating protein, tyrosine-protein kinase and etc. Inhibition of these targets can prevent the formation of uric acid, reduce inflammation by uric acid and regulate the body's immune response. Thus, these compounds may be the main effective substance basis. The research results not only reveals its molecular mechanism, but also provide a theoretical basis for the quality control of drugs and clinical application.

The present study investigated the therapeutic efficacy and potential mechanism of Jinqi Jiangtang Tablets(JQJT) on pancreatic β cell dysfunction based on network pharmacology and molecular docking technology. TCMSP platform was used to retrieve the chemical components and targets of the three Chinese herbal medicines of JQJT. The genes were converted to gene symbol by the UniProt, and its intersection with targets related to pancreatic β cell function in GeneCards and CTD databases was obtained. The drugs, active components and common targets were imported into Cytoscape 3.8.2 to plot the drug-component-target network. The main effective components and targets were obtained by software analysis. The drug targets and targets related to pancreatic β cell function were imported separately into the STRING platform for the construction of protein-protein interaction(PPI) networks. The two PPI networks were merged by Cytoscape 3.8.2 and the key targets were obtained by plug-in CytoNCA. The targets obtained from drug-component-target network and PPI networks were imported into DAVID for GO analysis and KEGG enrichment analysis. AutoDock was used to carry out molecular docking of main active components and core targets and Pymol was used to plot the molecular docking diagram. The results showed that there were 371 active components and 203 targets related to JQJT and 2 523 targets related to pancreatic β cell damage, covering 136 common targets. The results revealed core targets(such as PTGS2, PTGS1, NOS2, ESR1 and RXRA) and effective key components(such as quercetin, kaempferol, luteolin, β-carotene and β-sitosterol). KEGG enrichment analysis indicated that apoptosis, inflammation, and other signaling pathways were mainly involved. Molecular docking results showed that the main active components could spontaneously bind to the targets. This study preliminarily revealed the mechanism of JQJT in improving pancreatic β cell damage through multi-component, multi-target and multi-pathway, and provided a theoretical basis for JQJT in the treatment of pancreatic β cell dysfunction.

Upholding the wisdom of traditional Chinese medicine that the therapeutic principle, method, formula and medicine are coherent with each other, we propose the technical methodology for intelligent creation of component-based Chinese medicine by integrating multidisciplinary knowledge such as artificial intelligence, pharmaceutical informatics, system pharmacology and phytochemistry. Taking the creation of Guanxinning Tablets as an example, we expound the technical principle for creating component-based Chinese medicine and briefly describe the design method for optimizing the entity of Chinese medicine efficacy by rational combination of active components. Our research sought to "clarify and explain" the mechanism of its clinical treatment action through multi-modal and multi-scale systematic pharmacology studies. This work emphatically demonstrates the pilot workshop and engineering validation platform based on the intelligent simulation of whole production process, and outlines the design principles of the intelligent production line for innovative Chinese medicine. The results of industrial research show that the ourself established method for evaluating the process quality controllability and intelligent production line can be applied to manufacturing Guanxining Tablets with high quality. Through the innovative research of multidisciplinary cross-border integration, the present work explored a new way for the creation of modern Chinese medicine.

To predict the targets of active ingredients of Kuihua Hugan Tablets by network pharmacology, and explore the "multi-component-multi-target-multi-pathway" hepatoprotective mechanism of action. First, through traditional Chinese medicine systems pharmacology(TCMSP) and TCM Database@Taiwan Database, main active ingredients of Kuihua Hugan Tablets were screened out based on oral bioavailability(OB), drug-likeness(DL) and effective half-lives(HL). The targets of active ingredients of Kuihua Hugan Tablets were predicted based on the PharmMapper method. Then, the prediction was conducted by screening the target genes associated with chronic hepatitis and early cirrhosis through CooLGeN and GeneCards databases. Target gene functions and signal pathways were analyzed by bioinformatics annotation database Metascape. Cytoscape software was used to construct the Kuihua Hugan Tablets ingredient-target and ingredient-target-pathway network. String database combined with Cytoscape software was used to construct the networks of component-target and component-target-pathway. STRING database was combined with Cytoscape software to draw protein-protein interaction(PPI) network and conduct network topology analysis. Finally, Systems Dock Web Site software was applied in verifying the molecular docking between active ingredients and potential protein targets. A total of 26 compounds and 509 potential targets were screened out from Kuihua Hugan Tablets in the experiment. The results of PPI network analysis indicated that albumin(ALB), insulin-like growth factor 1(IGF1), matrix metalloproteinase-9(MMP9), matrix metalloproteinase-2(MMP2), non-receptor tyrosine kinase proto-oncogene(SRC), estrogen receptor 1(ESR1) and cancer-signal transduction-inflammation-drugs metabolism-related biological processes and metabolic pathways were closely associated with the active ingredients in Kuihua Hugan Tablets. The effects of Kuihua Hugan Tablets in alleviating chronic hepatitis and early cirrhosis indicated the multi-component, multi-target, and multi-pathway characteristics of traditional Chinese medicines, providing new ideas for further research and development of Kuihua Hugan Tablets.

To explore the new pattern of Chinese medicine solid preparations (CMSP) in vitro dissolution, a method testing the bio-thermal activity in combination with UPLC was used. Microcalorimetry was used to obtain the characteristic metabolic growth power-time curves and a series of biothermodynamic parameters of the inhibition of Staphylococcus aureus by Yinhuang tablet dissolving solutions at the pH 6.8 (phosphate buffer) dissolution medium at different times. From these results, the cumulative dissolution of Yinhuang tablet based on bio-thermal activity was obtained. The dissolution rates of two components of chlorogenic acid and baicalin were determined by UPLC method. Then f2 similar factor method was used to evaluate the relevance of these two methods. The result showed that f2 values all were more than 50, indicating that there is a good correlation between the two methods of measuring the dissolution rate. It is feasible to determine CMSP in vitro dissolution by using bio-thermal activity, and to provide new evaluation methods for controlling the quality of CMSP.

OBJECTIVETo observe the clinical effect of Huikangling Tablet (HT, extracted from Scabrous Patrinia root) on peripheral blood micrometastasis of differentiated thyroid carcinoma (DTC) patients.

METHODSTotally 87 DTC patients with positive micrometastasis were randomly assigned to the treatment group (45 cases) and the control group (42 cases). DTC endocrine inhibition treatment standards were executed in all patients. They all took levothyroxine sodium (50 microg/tablet, from low dose, 25 microg each time, once per day, 0.5 h before breakfast), and its dosage was gradually added one week later. The dosage was adjusted according to tested results of TSH combined recurrence risk stratification and endocrine suppression induced adverse reactions risk stratification. Patients in the treatment group took HT (0.4 g per tablet, 3 tablets each time, three times per day for a total of 12 weeks) combined TSH suppression therapy, while those in the control group only received TSH suppression therapy. Peripheral micrometastatic cytokeratin 19 (CK19) and polymorphic epithelial mucin1 (MUC1) were detected by FCM at week 4 and 12. Meanwhile, distant metastasis and adverse reactions were observed.

RESULTSAfter 4-week treatment positive micrometastasis was shown in 18 cases (40%) of the treatment group and 29 cases (69%) in the control group with statistical difference (chi2 = 5.68, P < 0.05). After 12-week treatment positive micrometastasis was shown in 7 cases (15.6%) of the treatment group and 17 cases (44.7%) in the control group with statistical difference (chi2 = 8.49, P < 0.01). Pulmonary metastasis occurred in 2 cases and bone metastasis in 1 case of the control group at follow-ups. Cervical lymph node metastasis without accompanied recurrence of thyroid cancer occurred in one case of the treatment group. No obvious liver or renal abnormalities occurred.

CONCLUSIONHT inhibited peripheral blood micrometastasis of DTC patients and its mechanism needed to be further studied.
