Objective This study was performed to investigate whether Bee Venom Pharmacopuncture(BVP) could be a more effective modality than Warm Needling(WN) in relieving pain and symptoms of knee osteoarthritis(OA). Design Prospective, randomized and controlled clinical trial. Setting Single center trial in Korea Patients 49 volunteers with knee OA participated in the study. All the participants were screened through an inclusion and exclusion criteria. 33 participants were completed the clinical trial. Intervention The subjects were randomly assigned to one of two groups. One group received BVP(n=18), while the other group received WN(n=15). Sixteen sessions of BVP or WN were given at the pain region of the problematic knee for 8 weeks. Primary outcome measure is the Korean translation of Western Ontario and McMaster Universities Osteoarthritis Index scores(Korean WOMAC, KWOMAC). Secondary outcome measure is the physical health scores based on the 36-Item Short-Form Health Survey(SF-36) and Patient Global Assessment(PGA). KWOMAC and SF-36 were measured third (baseline, 4 and 8 weeks). PGA was measured twice(4 and 8 weeks). Results BVP group showed significant decrease compared to WN group in pain, function and total scores of KWOMAC according to the Mann-Whitney U-test. In the PGA, BVP group, compared to WN group, showed a significant increase. Conclusions BVP was more effective in relieving pain of knee OA than WN. These findings suggest that BVP is a promising alternative for treating knee OA.

Objectives : This study aimed to predict the effectiveness and potential of Schizonepeta tenuifolia as an anticancer treatment for non-small cell lung cancer through network-based pharmacology and cellular experiment. Methods : To identify the major bioactive compounds in Schizonepeta tenuifolia, we used the Traditional Chinese Medicine Systems. The target genes for the cancer treatment were selected using the UniProt database and the networked using Cytoscape. We performed functional enrichment analysis based on the Gene Ontology Biological Process and Kyoto Encyclopedia of Genes and Genomes Pathways to predict the mechanisms. To investigate the effect of Schizonepeta tenuifolia on lung cancer cell growth, we treated A549 cells, a lung cancer cell line, with different concentrations of the drug and used the MTT assay for cell viability. Results : Research has shown that the most effective mechanism of active compounds from Schizonepeta tenuifolia is through the pathway of cancer. The results of the network pharmacology analysis indicate that Schizonepeta tenuifolia has potential medicinal value as an adjuvant in anticancer treatment. The concentration-dependent inhibition of cell viability was observed on A549 cells. Furthermore, synergistic anticancer activity with Doxorubicin was also observed. Conclusions : Through a network pharmacological approach, Schizonepeta tenuifolia was predicted to have potential as an anticancer agent, and its efficacy was experimentally demonstrated using A549 cells. These findings suggest that Schizonepeta tenuifolia is a promising candidate for future research.

Recently, interest of polymer light-emitting diode (PLED) fabricated from conjugated polymer has augmented because PLED has advantage property that is well-suited to flexible lighting and solution processed device. In this presentation, we suggest a new polymer host based on phenanthrene, poly(9-(3-Vinyl-phenyl)-phenanthrene) (PVPP). It can be easily synthesized through simple synthetic methods which are Suzuki and Wittig reactions. From NMR data, vinyl group protons were disappeared and aromatic protons showed broad proton peaks because of polymer characteristics. PVPP film can be obtained from spin coating with solution used by common solvent. It exhibited PL maximum value of 381nm and broad PL spectrum of 70nm FWHM value. Energy transfer smoothly occurred when the three dopants for green, red and yellow were used in PVPP.
