The five-flavor theory of traditional Chinese medicines (TCM) and the flavor efficacy generation mechanism has long been focuses and difficulties in studies on traditional Chinese medicinal properties. In this paper, by using the pharmacophore-based virtual screening technique, the authors discussed the relations between the pungent property and transient receptor potential vanilloid 1 (TRPV1) by studying the TCM components' role in regulating TRPV1 ion channel. The results showed that the matching relationship between TRPV1 agonist pharmacophore model and TCM chemical components could identify the active ingredients from pungent herbs. Therefore, the authors proposed that TRPV1 is one of the potential targets for efficient pungent herbs. The pungent property of TCMs is decided by its chemical components, and consistent with the inherited and additive characteristics.

Dalbergiae Odoriferae Lignum as a traditional Chinese medicine (TCM) has been widely used for promoting blood circulation and removing blood stasis. Flavonoid compounds are main chemical constituents of Dalbergiae Odoriferae Lignum, which exert anti-inflammatory property. However, the underlying anti-inflammatory mechanisms of flavonoid compounds are incompletely understood. It has been reported that isoliquiritigenin, liquiritigenin, naringenin and butein possess anti-inflammatory property. The purpose of this study is to illuminate the anti-inflammatory mechanism of flavonoid compounds based on the protein interaction network (PIN) analysis on molecular network level. 130 targets of the main medicinal ingredients of flavonoid compounds were gained though database retrieval. A protein interaction network of flavonoid compounds was constructed with 589 nodes and 216 interactions. By a graph theoretic clustering algorithm Molecular Complex Detection (MCODE), 26 modules were identified and analyzed by Gene ontology (GO) enrichment. Two modules were associated with anti-inflammatory actions. The most interesting finding of this study was that the anti-inflammatory effect of flavonoid compounds may be partly attributable to inhibite FOS, PTGS2 expression, inhibite of IL-1beta release, and block the MAPK pathway and toll-like receptor pathway.

Aim To test the skin healing and repairing efficacy and the mechanism of Hibiscus rosa-sinensis L bud extract by using the animal models. Methods KM mice were randomly divided into three groups:the model group, the positive control group, and the n-bu-tyl alcohol extract ( HrBN) group. Using the boils and carbuncles model, the healing condition of all the animals were observed. KM mice were kept in the SPF condition room and divided into five groups: the model group, the positive control group, and the low, middle, high dose groups. Using the full-thickness loss model, the repairing results of all the mice were ob-served. Through the antimicrobial test, the results of MIC and inhibition zone were obtained. The carbon clearance test was used to collect the blood at the time 5min and 15min, and get the liver and spleen, and the results of K andαwere obtained. Results In vivo ex-periments showed there was significant difference be-tween groups;the HrBN extract had the outstanding ef-ficacy in healing and repairing skin boils and full-thickness loss models. It had higher recovery rate than other ethanol extract, such as ethyl acetate extract and chloroform extract. In vitro experiments showed that the HrBN extract, ethyl acetate extract ( HrBE) ,AB-8 macroporous resin 30% alcohol part and 60% alcohol part had obvious antimicrobial efficacy. The carbon clearance test showed HrBN had a good effect in im-proving immune function, and it can increase the K and α. Conclusion HrBN in animal models exerts good skin healing and repairing efficacy, which might be related to its antibacterial activity and immunologic enhancement function.

Panax notoginseng (PN) is one of the commonly used clinical medicines for cardiovascular diseases and possesses a variety of pharmacological effects. P. notoginseng saponins (PNS) are the most important bioactive components in PN. The purpose of this study was to explain the mechanism of PNS on molecular network level. 18 targets of the main medicinal ingredients of PNS were gained by virtual screening based on pharmacophores and data mining. A protein interaction network of PNS was constructed with 189 nodes and 721 interactions. By a graph theoretic clustering algorithm Molecular Complex Detection (MCODE), 14 modules were detected. Gene ontology (GO) enrichment analysis of the modules demonstrated that the roles of PNS played in cardiovascular disease related to multiple biological processes, which could represent the characteristics of traditional Chinese medicine (TCM) as a whole to regulate the disease. The results showed that the blood circulation and hemostasis efficacy of PN related with the biological processes such as positive regulation of cAMP metabolic and biosynthetic process, platelet activation and regulation of blood vessel size, regulation of T cell proliferation and differentiation and so on. Therefore, the module-based network analysis will be an effective method for better understanding TCM.

Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

Objective To observed hepatolenticular degeneration gene (ATP7B gene) expressed in Me32aT22/2L cell and detected whether A TP7B could transport redundant copper and reduce copper-induced cell apoptosis, which will make the basement for future gene therapy. Methods Piasmid pRc/CMV-WD containing A TP7B cDNA was transfected into Me32aT22/2L cell using lipofectamin2000 transfection methods. Intracellular distribution of ATP7B was detected by immunofluorescence histochemistry method and copper transportation function was studied using high-concentration copper incubation experiments, meanwhile, cell apoptosis induced by high-concentration copper incubation was observed. Results Expression of A TB7B gene could be detected and located around nuclei within the Me32aT22/2L cell. After incubation of high- concentration copper solution after 24, 48 and 72 hours, in empty vector group intracellular copper content was (600.60±69.71) ng/mg, (890.72±65.74) ng/mg and (1189.20±85.71) ng/mg respectively, however, intracellular copper content was (351.33±49.86) ng/mg, (427.38±30.95) ng/mg and (539.10±34.91) ng/mg in A TP7B group. Comparison of two groups has a statistical significance (P<0.01). Meanwhile, cell apoptotic rate was markedly decreased in A TPTB group compared with empty vector group (P<0.01). Conclusion Exogenous A TP7B gene could be expressed in Me32aT22/2L cell and A TPTB could transport intracellular redundant copper, subsequently reduced copper-induced cell apoptosis.
