In this study we investigated the role and mechanism of cardamonin on IL-1β induced injury in OA. CHON-001 cells were treated with cardamonin and IL-1β and transfected with silencing nuclear factor erythroid 2-related factor 2 (siNrf2). Cell viability was detected by Cell Counting Kit-8 assay and flow cytometer assay was utilized for cell apoptosis assessment. IL-6, IL-8, TNF-α and Nrf2 mRNA expression was tested by qRT-PCR. Western blot was employed to evaluate MMP-3, MMP-13, Collagen II, Nrf2, NQO-1, NLRP3, Caspase 1 and apoptosis-associated speck-like protein containing a caspase-1 recruitment domain (ASC) protein levels. In CHON-001 cells, IL-1β suppressed cell viability and Collagen II level while promoting cell apoptosis and expression of pro-inflammatory cytokines (IL-6, IL-8, TNF-α), MMPs (MMP-3, MMP-13), NQO-1, and NLRP3 inflammasome (NLRP3, Caspase 1 and ASC), with no significant influence on Nrf2. Cardamonin reversed the effect of IL-1β on cell viability, cell apoptosis, pro-inflammatory cytokines, MMPs, Collagen II, and NLRP3 inflammasome levels. In addition, cardamonin advanced Nrf2 and NQO-1 expression of CHON-001 cells. SiNrf2 reversed the function of cardamonin on IL-1β-induced cell apoptosis and expression of pro-inflammatory cytokines, Nrf2, NQO-1, and NLRP3 inflammasome in chondrocytes. Taken together Cardamonin inhibited IL-1β induced injury by inhibition of NLRP3 inflammasome via activating Nrf2/NQO1 signaling pathway in chondrocyte.

Oral squamous cell carcinoma (OSCC) is mostly diagnosed at an advanced stage, with local and/or distal metastasis. Thus, locoregional and/or local control of the primary tumor is crucial for a better prognosis in patients with OSCC. Platelets have long been considered major players in cancer metastasis. Traditional antiplatelet agents, such as aspirin, are thought to be potential chemotherapeutics, but they need to be used with caution because of the increased bleeding risk. Podoplanin (PDPN)-expressing cancer cells can activate platelets and promote OSCC metastasis. However, the reciprocal effect of platelets on PDPN expression in OSCC has not been investigated. In this study, we found that direct contact with platelets upregulated PDPN and integrin β1 at the protein level and promoted invasiveness of human OSCC Ca9.22 cells that express low levels of PDPN. In another human OSCC HSC3 cell line that express PDPN at an abundant level, silencing of the PDPN gene reduced cell invasiveness. Analysis of the public database further supported the co-expression of PDPN and integrin β1 and their increased expression in metastatic tissues compared to normal and tumor tissues of the oral cavity. Taken together, these data suggest that PDPN is a potential target to regulate platelet-tumor interaction and metastasis for OSCC treatment, which can overcome the limitations of traditional antiplatelet drugs.

Dynamic orphism images expressed with abstraction and construction in color are often found in modern fashion. Orphism stressing color is one of the many art trends that influence fashion. This work aims to examin its expressive effects and characteristics that appear in fashion and provide basic materials for fashion design study. This study proceeds with the following steps. First, the study takes on a theoretical examination of the orphism trend using a literature review. Second, based on its results, modern fashion's expressive features influenced by orphism are analyzed. Third, the study draws expression effects in modern fashion from these characteristics. The study coverage is confined to domestic and foreign collections released in the 21st century. The study contents come from an Internet-base domestic and international database and published material, including dissertations and books. Orphism expression effects are found in the following ways in modern fashion. First, it lies in the abstraction effect of color. This feature arrays flat geometric figure on the clothing surface and applies a strong sense of color inside it, as if color has an abstractive structured design. Second, it gives a dynamic sense visually to the clothes all at once by stressing the relation among and between the colors with powerful contrast. Third, it has a collage effect of color. This effect develops into an organic combination composed of geometric plane figures with intense complementary colors in a single piece of clothing. Expression types that presents the orphism effect in fashion are divided into clothing showing traditional orphism characteristics faithfully and clothing expressing conventional orphism characteristics mixed with modern trends. Further developed orphism fashion can be classified by the playful type, with graffiti added onto an orphism color structure, and the destructive type, where traditional orphism color orders are taken apart and reformed into a new color order.
BACKGROUND/OBJECTIVES: Sanghuangporus sanghuang (SS) has various medicinal effects, including anti-inflammation and anticancer activities. Despite the extensive research on SS, its molecular mechanisms of action on lung cancer are unclear. This study examined the impact of an SS alcohol extract (SAE) on lung cancer using in vitro and in vivo models. MATERIALS/METHODS: Different concentrations of SAE were used to culture lung cancer cells (A549 and H1650). A cell counting kit-8 assay was used to detect the survival ability of A549 and H1650 cells. A scratch assay and transwell cell invasion assay were used to detect the migration rate and invasive ability of SAE. Western blot analysis was used to detect the expression of B-cell lymphoma-2 (Bcl-2), Bcl2-associated X (Bax), cyclin D1, cyclin-dependent kinases 4 (CDK4), signal transducer and activator of transcription 3 (STAT3), and phosphorylated STAT3 (p-STAT3). Lung cancer xenograft mice were used to detect the inhibiting ability of SAE in vivo. Hematoxylin and eosin staining and immunohistochemistry were used to detect the effect of SAE on the structural changes to the tumor and the expression of Bcl-2, Bax, cyclin D1, CDK4, STAT3, and p-STAT3 in lung cancer xenograft mice. RESULTS: SAE could inhibit lung cancer proliferation significantly in vitro and in vivo without cytotoxicity. SAE suppressed the viability, migration, and invasion of lung cancer cells in a dose and time-dependent manner. The SAE treatment significantly decreased the proapoptotic Bcl-2/Bax ratio and the expression of pro-proliferative proteins Cyclin D1 and CDK4 in vitro and in vivo. Furthermore, SAE also inhibited STAT3 expression. CONCLUSIONS: SAE reduced the cell viability and suppressed cell migration and invasion in human lung cancer cells. Moreover, SAE also exhibited anti-proliferation effects in vivo. Therefore, SAE may have benefits in cancer therapy.
Objectives : This study evaluates how various traditional Korean herbal medicines assess MUC5AC expression for esophageal mucosal defense and analyzes the associated mechanisms involved in inflammation. Methods : Forty types of traditional Korean herbal medicines were assessed for in vitro antioxidant activities, and the real-time PCR method was employed to analyze MUC5AC expression under pH 4.5 conditions in human esophageal epithelial cells (HET-1A). Eight types of Korean herbal medicines were evaluated for in vitro antioxidant activities, and Reactive oxygen specise (ROS) expression was analyzed under bile salt (480 𝜇M) and pH 5.5 conditions in human esophageal epithelial cells (HET-1A). Simulation experiments involving bile salts and acidity were conducted for one hour to assess the efficacy of four drugs, and the activities of Mitogen-activated Protein Kinase (MEK), Nuclear Factor Kappa B (NF-𝜅B), and Cyclooxygenase-2 (COX-2) were detected through Western blot analysis. Results : Compared to the Normal group, the Control group exhibited higher ROS generation. Such increased ROS levels were significantly reduced by four extracts: Citrus Unshius Pericarpium (CUP), Cnidium officinale Rhizoma (CR), Ginseng Radix (GR), and Linderae Radix (LR). The protein expression of COX-2 decreased with the treatment of LR, CUP, and CR. Particularly, CUP and CR exhibited superior effects compared to other groups in inhibiting the phosphorylation of NF-𝜅B. Conclusion : Based on the results obtained, we have identified drugs that inhibit oxidative stress and inflammation caused by bile acid in esophageal epithelial cells. Our future plans involve comparing and analyzing the efficacy of these herbal medicines through animal experiments.
In general, Reucedani Radix (Peucedanum japonicum Thunbergis: PJ) is the Korean traditional herbal medicine used to remove dampness, to relieve pain, and spasm. So, PJ folium is believed to have the same effects. The aim of this study is to investigate the alleviation of dextran sulfate sodium (DSS) induced ulcerative colitis in mice by PJ folium. 25 mice were divided into 5 groups: normal, DSS, DSS + 100 mg/kg PJ folium (PJ100), DSS + 500 mg/kg PJ folium (PJ500), and DSS + 150 mg/kg 5-amino salicylic acid (5-ASA) groups. Body weights, colon lengths, histological changes in colon tissue, and spleen weights were observed. Inflammatory cytokines such as IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ level in plasma were measured by ELISA. IL-$1{\beta}$, IL-6, and TNF-a mRNA expression in colon tissue were detected by RT-PCR. In the results, body weight lose was inhibited in PJ100, PJ500, and 5-ASA groups, but it was not different compared with DSS group, significantly. PJ500 group showed the preventive effects of colon length shorten and histological changes in colon tissues as good as 5-ASA group. The weight of spleen was increased in DSS group but it reduced in PJ100, PJ500, and 5-ASA groups. Moreover, IL-$1{\beta}$ and TNF-${\alpha}$ cytokine levels in plasma were reduced in PJ500 and 5-ASA groups. IL-$1{\beta}$, IL-6, and TNF-a mRNA expression in colon tissue were inhibited in PJ100, PJ500, and 5-ASA groups and it was significantly different compared with DSS group. In conclusion, PJ folium showed the alleviative effect on DSS induced ulcerative colitis in mice.

Accurately predicting cancer prognosis to provide appropriate treatment strategies for patients is one of the critical challenges in bioinformatics. Many researches have suggested machine learning models to predict patients' outcomes based on their gene expression data. Gene expression data is high-dimensional numerical data containing about 17,000 genes, so traditional researches used feature selection or dimensionality reduction approaches to elevate the performance of prognostic prediction models. These approaches, however, have an issue of making it difficult for the predictive models to grasp any biological interaction between the selected genes because feature selection and model training stages are performed independently. In this paper, we propose a novel two-dimensional image formatting approach for gene expression data to achieve feature selection and prognostic prediction effectively. Node2Vec is exploited to integrate biological interaction network and gene expression data and a convolutional neural network learns the integrated two-dimensional gene expression image data and predicts cancer prognosis. We evaluated our proposed model through double cross-validation and confirmed superior prognostic prediction accuracy to traditional machine learning models based on raw gene expression data. As our proposed approach is able to improve prediction models without loss of information caused by feature selection steps, we expect this will contribute to development of personalized medicine.
Objectives : Bojungikgitang (BJT), the Oriental medical prescription has been traditionally used about improvement of immune response and infective disease at Asian nation. In this study, we has compared about the anti-inflammatory and antioxidative effects on BJT of three countries including Korea (Korean Traditional Medicine, KTM), China (Traditional Chinese Medicine, CTM) and Japan (Japanese Traditional Medicine, JTM). Methods : We has basically using LPS-stimulated RAW 264.7 cells. The expression of these inflammatory mediators has measured using enzyme-linked immunosorbent assay (ELISA) and reverse transcription polymerase chain reaction (RT-PCR). Also, free radical scavenging assay has tested for anti-oxidative activity as well as the contents of total flavonoid and polyphenol. Results : As a result, we were founded the inhibitory effects of BJT (KTM, CTM, JTM) on LPS-induced production of NO, TNF-${\alpha}$ and IL-6 as well as the anti-oxidative activities. Especially the KTM was most effective in anti-inflammatory and anti-oxidative activities. Conclusions : These results indicate that BJT (KTM, CTM, JTM) has a good anti- inflammatory and anti-oxidative effects. But, there were degree of effects on between pharmacopoeia of the countries. Thus, further study is required that find appropriate methods for extracting as well as establish of standardized processes in order to improve the quality of BJT (KTM, CTM, JTM) as an anti-inflammatory and anti-oxidative agent for treatment of inflammatory diseases.
The purpose of this study was to investigate the characteristic as to how the Indonesian traditional space is expressed in a contemporary space. As for the study method, We visited 12 Indonesian restaurants in Jakarta from Oct. 16 to Oct. 20, 2010 for a case study. The study result is presented as follows: First, as a factor of facade components, the roof part revealed its identity as a Joglo structure. Walls, windows and doors reflected Indonesian tradition, or were transformed in passive or aggressive ways. Second, as a factor of interior space components, ceilings were predominantly designed by reflecting a structural exposure ceiling or Tumpang Sari as it was or by passively transforming them; Interior walls, windows and doors were transformed in aggressive ways. Third, regarding the factors of interior decoration components, traditional furniture was not used, but instead, furniture with contemporary form and local materials were dominently used, and traditional accessaries were used as they were. Therefore, in the case of designing spatial componentss in Indonesian restaurants located in Jakarta, roofs and ceilings, floors, furniture, and accessaries reflected Indonesian tradition, or were passively transformed, whereas walls, windows, doors, and some ceilings aggressively reflected modernized tradition so that they were formed in harmony with traditional and contemporary styles.
This work developed the basic motive design utilizing the physical beauty of the traditional ornaments used uniquely by Korean females and suggested some textile designs and fashion cultural product designs. As a research method, computer design programs Adobe Illustrator CS3 and Adobe Photoshop CS3 were used as well as literature examination. The motive was mainly based on the dwiggoji and ddeoljam, which are female ornaments. The formative shape in woman ornaments was classified into four kinds: plant, animal, geometry, and hybrid. The hybrid type was divided further into such combinations as plant, animal, and geometry, which came up with 8 fundamental motives for design development in total. With regard to the basic motive design, the coordinated concept was adopted with a combination of traditional taste and contemporary taste in harmony for the expression of delicate image on the condition that the basic format in female ornament is maintained. Textile design was processed with symmetry, rotation, repeat, and overlap as fundamental motive. As to the design for fashion cultural products, design mapping was proposed for neckties, handbags, clutches, shirts, and one-pieces. Utility and beauty in the traditional ornaments unique to Korean women could be recognized once again through this work. This work also assured the possibility for the endless improvement as a design development motive with originality.
