      • On the Supply-side Reform in Martial Arts Field

        ( Qiao Feng Jie ) 대한무도학회 2019 대한무도학회 학술대회자료집 Vol.2019 No.2

        This study suggests that a problem facing the field of martial arts today is the mismatch between supply and demand. The best way to solve this problem is to carry out supply-side reforms in the martial arts field and let martial arts meet the diverse needs of modern people. Specific measures are as follows: improve the quality of martial arts products, upgrade the services system of martial arts and improve the social ecology of martial arts. Purpose: The purpose of this study was to solve the mismatch problem between supply and demand, and let martial arts meet the diverse needs of modern people. Methods: participant observation, philosophical speculation. Conclusion: 1. A problem facing the field of martial arts today is the mismatch between supply and demand and supply-side reform is the best way to solve this problem. 2. To carry out supply-side reforms in martial arts field, we should focus on the following work: (1) Improve the quality of martial arts products: make features of different kinds of martial arts distinctive and make the customized martial arts program common; (2) Upgrade the services system of martial arts: construct information processing system, training aid system and competition organization system for martial arts; (3) Improve the social ecology of martial arts: martial arts plus fashion social platform, martial arts plus creativity implantation culture and martial arts plus other related industries.

      • Radiation Induces Phosphorylation of STAT3 in a Dose- and Time-dependent Manner

        Gao, Ling,Li, Feng-Sheng,Chen, Xiao-Hua,Liu, Qiao-Wei,Feng, Jiang-Bin,Liu, Qing-Jie,Su, Xu Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

        Background: We have reported the radiation could activate STAT3, which subsequently promotes the invasion of A549 cells. We here explored the dose- and time-response of STAT3 to radiation and the effect of radiation on upstream signaling molecules. Materials and Methods: A549 cells were irradiated with different doses of ${\gamma}$-rays. The expression of and nucleus translocation of p-STAT3 in A549 cells were detected by immunoblotting and immunofluorescence, respectively. The level of phosphorylated EGFR was also assessed by immunoblotting, and IL-6 expression was detected by real time PCR and ELISA. Results: Radiation promoted the phosphorylation of STAT3 at Y705 in a dose- and time-dependent manner and nuclear translocation. The level of phosphorylated EGFR in A549 cells increased after radiation. In additional, the mRNA and protein levels of IL-6 in A549 cells were also up regulated by radiation. Conclusions: STAT3 is activated by radiation in a dose-and time-dependent manner, probably due to radiation-induced activation of EGFR or secretion of IL-6 in A549 cells.
