        有關新時期中國 "校園語言" 的思考

        張進軍 한국중국문화학회 2002 中國學論叢 Vol.14 No.-

        본 논문은 "校園語言"의 특성, 발생원인 및 "校園語言"을 어떻게 파악하고 받아 들여야하는가등의 문제를 다루고 있다. 사회 언어학의 관점에서 보면, "校園語言"는 바로 일종의 언어 變異이며, 또한 언어 운용상의 變異이기도하다. 청소년들은 언어의 "창조적인 운용"에서 "新","奇","異",등의 효과를 나타낸다. 그리고 變異가 나타나는 원인은 사회경제와 문화의 두가지 큰 환경으로서, 캠퍼스 환경은 청소년기에 특수한 심리 영향을 파급시킨다. 그리고 캠퍼스 언어 현상을 어떻게 받아들일것인가에 대해서는, 책망을 하기보다는 유리한 방향으로 유도하고 규범화시키며, 대중문화의 청소년들에 대한 인도 작용을 염두에 두어야 한다.

        Anomalous magnetization jumps in granular Pb superconducting films

        Zhang An-Lei,Jiang Wan-Yan,Chen Xing-Hong,Zhang Xiao-Ke,Lu Wen-Lai,Chen Fei,Feng Zhen-Jie,Cao Shi-Xun,Zhang Jin-Cang,Ge Jun-Yi 한국물리학회 2022 Current Applied Physics Vol.35 No.-

        In granular superconductors, the grain boundaries are closely related to the vortex dynamics and the macroscopic superconducting properties. In our research, Pb films with different grain sizes were prepared by tuning the substrate temperature. With the grain size decreasing, Pb films are prone to feature the anomalous magnetization jumps in the M − T curves, while in the M − H curves flux avalanche happens. Both phenomena appear in the same region of the H − T phase diagram and thus are considered to have the same origin. The further theoretical analysis shows that with grain size decreasing the pinning mechanism evolves from a mixed δTc and δl pinning to the δl pinning mechanism. The results shed light on the study of pinning mechanism for granular superconductors and is beneficial to the potential application of manipulating vortex pinning by regulation of intrinsic defects.

      • Macrophages Promote Coal Tar Pitch Extract-induced Tumorigenesis of BEAS-2B Cells and Tumor Metastasis in Nude Mice Mediated by AP-1

        Zhang, Peng,Jin, Yue-Fei,Zhang, Qiao,Wu, Yi-Ming,Wu, Wei-Dong,Yao, Wu,Wu, Yong-Jun,Li, Zhi-Tao,Zhao, Yong,Liu, Yu,Feng, Fei-Fei Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.12

        Background: We sought to evaluate the role of tumor associated macrophages (TAMs) on the promotion of coal tar pitch extract (CTPE)-induced tumorigenesis of human bronchial epithelial cells (BEAS-2B) and tumor metastasis in nude mice, and related mechanisms. Materials and Methods: BEAS-2B cells were first treated with 2.4 mg/mL CTPE for 72 hours. After removal of CTPE, the cells were continuously cultured and passaged using trypsin-EDTA. THP-1 cells were used as macrophage-like cells. BEAS-2B cells under different conditions (n=6/group) were injected into the back necks of nude mice, and alterations of tumor xenograft growth, indicative of tumorigenicity, and tumor metastasis were determined. Pathological changes (tumor nests and microvascular lesions) of HE-stained tumor tissues were also evaluated. The expression of AP-1(c-Jun) in xenografts and metastatic tumors was determined using immunohistochemistry. Results: Tumor size and weight in nude mice transplanted with the mixture of CTPE-induced passage 30 BEAS-2B and THP-1 cells (2:1) were increased compared to those from the CTPE-treated BEAS-2B cells at passage 30 alone at different observation time points. Tumor metastasis to lymph nodes and liver was only detected after transplantation of a mixture the two kinds of cells. The numbers of tumor nests and microvascular lesions, and the expression levels of AP-1 (c-Jun) in tumors from the mixture of two kinds of cells were increased apparently in contrast to those in tumor from the CTPE-treated BEAS-2B cells of passage 30 alone. In addition, there was positive correlation between AP-1 (c-Jun) expression level and the number of microvascular lesions, or between AP-1 (c-Jun) expression level and tumor metastasis in these two groups. Conclusions: TAMs not only facilitate tumorigenesis transformation of CTPE-induced BEAS-2B cells, but also promote tumor growth, angiogenesis and metastasis in nude mice in vivo, which may be mediated by AP-1.

      • Improving ginsenoside content in Korean wild ginseng by Agrobacterium-mediated transformation with a squalene synthase ge

        Jun-Ying Zhang,Hyeon-Jin Sun,In-Ja Song,Hong-Gyu Kang,Suk-Min Ko,Yong-Ik Kwon,Il-Woung Kim,Jae-Hoon Kim,Hyo-Yeon Lee 한국육종학회 2014 한국육종학회 심포지엄 Vol.2014 No.07

        With the purpose of improving ginsenoside production in Korean wild ginseng (Panax ginseng Meyer) mutant adventitious root lines, a synthetic gene encoding squalene synthase (PgSS2) was placed under the control of 35S promoter and transferred to Panax ginseng. Embryogenic callus obtained from ginseng adventitious root lines were transformed by infection with A. tumefaciens strain EHA105 containing the PgSS2 gene. Ten phosphinothricin-resistant plants were generated on selection medium, and the transgene integration and expression in these plants were confirmed by PAT test strip, RT-PCR and Southern hybridization. Ginsenoside analysis by HPLC revealed that the total contents of the 8 ginsenoside types (Rg1, Re, Rf, Rh1, Rb1, Rc, Rb2, Rd) in transgenic adventitious root lines were about 1.6-fold higher than that of the mutant control line (MCL1). This transformation method may facilitate the improvement of Panax ginseng in terms of the accumulation levels of ginsenoside.

      • Suitability of Fourier Transform Infrared Spectroscopy as a screening method for the production of useful mutant lines in Panax ginseng

        Javzandulam Ulziisaikhan,Jun-Ying Zhang,Hong-Yu Li,Hyeon-Jin Sun,Somi Kim,Sung-Jun Song,Hyo-Yeon Lee 한국육종학회 2015 한국육종학회 심포지엄 Vol.2015 No.07

        Panax ginseng C.A Meyer is commonly used in Asian traditional medicine to treat a variety of diseases. Ginsenosides are glycosylated triterpenes, referred to saponins, have been especially noted as active compounds contributing to the various efficacy of ginseng. In this study, we are trying to select high saponin content of ginseng lines from the gamma irradiated adventitious roots. Recently, we have generated several mutant ginseng lines improving ginseniside content by gamma radiation. The mutant lines were selected by phenotypes and ginsenoside content (HPLC analysis) of the irradiated adventitious root lines. However, the ginsenoside content of the mutant lines was not sufficient for commercial use and the selection method was not suitable for large scale of mutant line selection. In this study, we are testing Fourier transfer infrared spectroscopy (FT-IR) as a new selection method of mutant lines in Panax ginseng. About 5,000 pieces of Panax ginseng adventitious roots were exposed to gamma radiation (60Co). Irradiation dosages were 0, 25, 50 and 70Gy. Survival rate of the irradiated samples was evaluated by counting the number of survival main roots after 5 weeks culture in the solid MS medium with NAA, IAA and 5% sucrose. In present, we are collecting the survived adventitious root lines (about 900 lines) from the gamma irradiated ginseng roots for FT-IR and HPLC analysis. After analysis of FT-IR and HPLC, we will assess the suitability of the FT-IR as a screening method for the preparation of mutant lines in ginseng.

      • Development and Evaluation of a Patient-Reported Outcome (PRO) Scale for Breast Cancer

        Zhang, Jun,Yao, Yu-Feng,Zha, Xiao-Ming,Pan, Li-Qun,Bian, Wei-He,Tang, Jin Hai Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.18

        Background: This study was guided by principles of the theoretical system of evidence-based medicine. In particular, when searching for evidence of breast cancer, a measuring scale is an instrument for evaluating curative effects in accordance with the laws and characteristics of medicine and exploring the establishment of a system for medically assessing curative effects. At present, there exist few tools for evaluating curative effects. Patient-reported outcomes (PROs) refer to outcomes directly reported by patients (without input or explanations from doctors or other intermediaries) with respect to all aspects of their health. Data obtained from PROs provide evidence of treatment effects. Materials and Methods: In accordance with the tenets of theoretical medicine and ancient medical theory regarding breast cancer, principles for developing a PRO scale were established, and a theoretical model was developed and a literature review was performed, items from this pool were combined and split, and an initial scale was constructed. After a pilot survey and additional modifications, a pre-questionnaire scale was formed and used in a field investigation. After the application of statistical methods, the item pool was used to create a formal scale. The reliability, validity and feasibility of this formal scale were then assessed. Results: In a clinical investigation, 479 responses were recovered, with an acceptance rate of 95%. a combination of various methods was employed, and the items that were selected by all methods or more than half of the methods were employed in the questionnaire. In these cases, the screening methods were combined with certain features of the item, A total of four domains and 38 items were reserved. The reliability analysis indicated that the PRO scale was relatively reliable. Conclusions: Scientific assessment proved that the proposed scale exhibited good reliability and validity. This scale was readily accepted and could be used to assess the curative effects of medical therapy. However, given the limited scope of this investigation, the capacity for adapting this scale to incorporate other theories could not be determined.

        Cashmere growth control in Liaoning cashmere goat by ovarian carcinoma immunoreactive antigen-like protein 2 and decorin genes

        Jin, Mei,Zhang, Jun-yan,Chu, Ming-xing,Piao, Jun,Piao, Jing-ai,Zhao, Feng-qin Asian Australasian Association of Animal Productio 2018 Animal Bioscience Vol.31 No.5

        Objective: The study investigated the biological functions and mechanisms for controlling cashmere growth of Liaoning cashmere goat by ovarian carcinoma immunoreactive antigen-like protein 2 (OCIAD2) and decorin (DCN) genes. Methods: cDNA library of Liaoning cashmere goat was constructed in early stages. OCIAD2 and DCN genes related to cashmere growth were identified by homology analysis comparison. The expression location of OCIAD2 and DCN genes in primary and secondary hair follicles (SF) was performed using in situ hybridization. The expression of OCIAD2 and DCN genes in primary and SF was performed using real-time polymerase chain reaction (PCR). Results: In situ hybridization revealed that OCIAD2 and DCN were expressed in the inner root sheath of Liaoning cashmere goat hair follicles. Real-time quantitative PCR showed that these genes were highly expressed in SF during anagen, while these genes were highly expressed in primary hair follicle in catagen phase. Melatonin (MT) inhibited the expression of OCIAD2 and promoted the expression of DCN. Insulin-like growth factors-1 (IGF-1) inhibited the expression of OCIAD2 and DCN, while fibroblast growth factors 5 (FGF5) promoted the expression of these genes. MT and IGF-1 promoted OCIAD2 synergistically, while MT and FGF5 inhibited the genes simultaneously. MT+IGF-1/MT+FGF5 inhibited DCN gene. RNAi technology showed that OCIAD2 expression was promoted, while that of DCN was inhibited. Conclusion: Activation of bone morphogenetic protein (BMP) signaling pathway up-regulated OCIAD2 expression and stimulated SF to control cell proliferation. DCN gene affected hair follicle morphogenesis and periodic changes by promoting transforming growth $factor-{\beta}$ ($TGF-{\beta}$) and BMP signaling pathways. OCIAD2 and DCN genes have opposite effects on $TGF-{\beta}$ signaling pathway and inhibit each other to affect the hair growth.
