'아속(雅俗)' 을 초월하여 : 김용의 성공과 무협소설의 나갈 길 The success of Jin Yong and the prospect of the heroic novel (武俠小說)

천핑위안 민족문학사학회 2000 민족문학사연구 Vol.16 No.-

The essay, dealing with heroic novels of Jin-Yong(金庸), is extracted from professor Chen's latest work, the Form and the Structure of the History of Literature(1999.3, Guangsi Education Publishing). The author of the essay, Chen Ping-Yuan received M. A in literature at Zhongshan University and Ph. D at Beijing University and presently he is the professor of the Chinese literature department and the academic adviser of the doctor's course in Beijing University. His academic concern has wide range, such as 20th century's Chinese literature, modem Chinese history of science, Chines novel and Chinese prose, and it came out in his writings, like Narrative Form of Chinese Novel and Chines Novel of 20th Century. Hitherto, Chinese heroic novel was always under-valued in the field of literature but the enormous popularity of one writer, Jin-Yong, was so powerful that his heroic novel became the matter of scientific concern not mention in Chinese academic world but in the international academic world. The essay, with reflection, criticizes his success from the viewpoint of modern Chinese literature so its subject is the interior case of the Chinese literature. For all, some issues, like the problem of vulgarity in literature, the excessive inclination toward pure literature and the inheritance of the literary tradition, which arise from argument on Chinese heroic novel, are crucial points of the history of Korean new literature. Therefore, our reviewing this essay can be a lesson for studying the history of modern Korean literature.

Interface-State Modeling of <tex> $\hbox{Al}_{2}\hbox{O}_{3}$ </tex>–InGaAs MOS From Depletion to Inversion

Chen, Han-Ping,Yuan, Yu,Yu, Bo,Ahn, Jaesoo,McIntyre, Paul C.,Asbeck, Peter M.,Rodwell, Mark J. W.,Taur, Yuan IEEE 2012 IEEE transactions on electron devices Vol.59 No.9

<P>This paper presents a detailed analysis of the multifrequency capacitance–voltage and conductance–voltage data of <TEX>$\hbox{Al}_{2}\hbox{O}_{3}/\hbox{n-InGaAs}$ </TEX> MOS capacitors. It is shown that the widely varied frequency dependence of the data from depletion to inversion can be fitted to various regional equivalent circuits derived from the full interface-state model. In certain regions, incorporating bulk-oxide traps in the interface-state model enables better fitting of data. By calibrating the model with experimental data, the interface-state density and the trap time constants are extracted as functions of energy in the bandgap, from which the stretch-out of gate voltage is determined. It is concluded that the commonly observed decrease of the 1-kHz capacitance toward stronger inversion is due to the increasing time constant for traps to capture majority carriers at the inverted surface.</P>

Chen-Chen Zhao,Yang Yang,Hai-tao Wu,Zhi-Mo Zhu,Yue Tang,Cui-Ping Yu,Na Sun,Qiang Lv,Jia-Run Han,Ao-Ting Li,Jia-Nan Yan,Yue Cha 한국식품과학회 2016 Food Science and Biotechnology Vol.25 No.6

The proteolysis in muscle tissues of sea cucumber Stichopus japonicus (sjMTs) was characterized. The proteins from sjMTs were primarily myosin heavy chains (MHCs), paramyosin (Pm), and actin (Ac) having a molecular mass of approximately 200, 98, and 42 kDa, respectively. Based on SDS-PAGE analysis and quantification of trichloroacetic acid (TCA)-soluble peptides released, degradation of muscle proteins from sjMTs was favorable at pH 5 and 50°C. Proteolysis of MHCs was mostly inhibited by cysteine protease inhibitors, including trans-epoxysuccinyl-L-leucyl-amido (4- guanidino) butane (E-64) and antipain (AP). E-64 and AP completely inhibited the degradation of Pm and Ac, while iodoacetic acid showed a partially inhibitory effect. These results indicated that the proteolysis of sjMTs was mainly attributed to cysteine proteases. Avoidance of setting the tissues at 40–50oC and slightly acidic condition and inhibition of cysteine proteases are helpful for decreasing sea cucumber autolysis.

Chen, Shao-Bin,Weng, Hong-Rui,Wang, Geng,Yang, Jie-Sheng,Yang, Wei-Ping,Liu, Di-Tian,Chen, Yu-Ping,Zhang, Hao Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.6

More studies are needed to clarify treatments and prognosis of early esophageal squamous cell carcinoma (ESCC). This retrospective study was designed to review the outcome of surgical treatment for early ESCC, evaluate the results of a left thoracotomy for selected patients with early ESCC, and identify factors affecting lymph node metastases and survival. The clinicopathological data of 228 patients with early ESCC who underwent transthoracic esophagectomy with lymphadenectomy without preoperative adjuvant treatment were reviewed. The ${\chi}^2$ test or Fisher's exact test were used to detect factors related to lymph node metastasis. Univariate and multivariate analyses were performed to identify prognostic factors. There were 152 males and 76 females with a median age of 55 years. Two hundred and eight patients underwent a left thoracotomy, and the remaining 20 patients with lymph nodes in the upper mediastinum more than 5 mm in short-axis diameter by computed tomography scan underwent a right thoracotomy. No lymph node metastasis was found in the 18 patients with carcinoma in situ, while lymph node metastases were detected in 1.6% (1/62) of patients with mucosal tumours and 18.2% (27/148) of patients with submucosal tumours. Only 7 patients showed upper mediastinal lymph node metastases in the follow-up. The 5- and 10-year overall survival rates were 81.4% and 70.1%, respectively. Only histologic grade (P<0.001) and pT category (P=0.001) significantly correlated with the presence of lymph node metastases. In multivariate analysis, only histologic grade (P=0.026) and pT category (P=0.008) were independent prognostic factors. A left thoracotomy is acceptable for selected patients with early ESCC. Histologic grade and pT category affected the presence of lymph node metastases and were independent prognostic factors for early ESCC.

Hispidin attenuates bleomycin‑induced idiopathic pulmonary fibrosis via an anti‑oxidative effect in A549 cells

Ren Chen-Xi,Jin Xin,Xie Dan-Ping,Guo Xiao-Yu,Yu Li-Yun,Cui Yu-Dong,Kwon Taeho,Sun Hu-Nan 한국응용생명화학회 2021 Applied Biological Chemistry (Appl Biol Chem) Vol.64 No.5

Idiopathic pulmonary fibrosis (IPF) is a serious and irreversible chronic lung disease. Bleomycin (BLM) is an anticancer drug, which can cause severe lung toxicity. The main target of oxidative stress-induced lung injury is alveolar epithelial cells, which lead to interstitial fibrosis. The present study investigated whether hispidin (HP), which has excellent antioxidant activity, attenuates bleomycin-induced pulmonary fibrosis via anti-oxidative effects in A549 cells. We found that hispidin reduced bleomycin-induced fibrosis of A549 cells by reducing reactive oxygen species (ROS) levels and inhibiting epithelial-mesenchymal transition. Taken together, our data suggest that hispidin has therapeutic potential in preventing bleomycin-induced pulmonary fibrosis.

Ou, Yu-Chen,Ngo, Si-Huy,Roh, Hwasung,Yin, Samuel Y.,Wang, Jui-Chen,Wang, Ping-Hsiung American Concrete Institute 2015 ACI structural journal Vol.112 No.5

<p>This research proposes innovative seven- and 11-spiral transverse reinforcement to replace two- and six-spiral reinforcement, respectively, to decrease spiral size to address the issue of spiral fabrication in large columns. Moreover, this research proposes using large reinforcing bars or H-shaped steel as longitudinal reinforcement to reduce the potential of reinforcing bar cage failure. The objectives of this research were to investigate the seismic performance of seven- and 11-spiral columns and the effect of using large reinforcing bars and H-shape steel as longitudinal reinforcement. Cyclic tests of columns showed that seven- and 11-spiral columns, even with less amounts of transverse reinforcement, exhibited higher ductility capacities than tied columns. The use of H-shaped steel as longitudinal reinforcement increased ductility and energy dissipation of the column. Among ACI 318, Caltrans BDS, and Caltrans SDC methods to estimate probable moment strength, only the Caltrans SDC method produced conservative results for all columns examined.</p>

Luo, Li-Ping,Han, Bin,Yu, Xiao-Ping,Chen, Xiang-Yan,Zhou, Jie,Chen, Wei,Zhu, Yan-Feng,Peng, Xiao-Li,Zou, Qiang,Li, Sui-Yan Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

Background: Increasing evidence from animal, epidemiological and clinical investigations suggest that dietary anthocyanins have potential to prevent chronic diseases, including cancers. It is also noteworthy that human epidermal growth factor receptor 2 (ErbB2) protein overexpression or ErbB2 gene amplification has been included as an indicator for metastasis and higher risk of recurrence for breast cancer. Materials and Methods: The present experiments investigated the anti-metastasis effects of black rice anthocyanins (BRACs) on ErbB2 positive breast cancer cells in vivo and in vitro. Results: Oral administration of BRACs (150 mg/kg/day) reduced transplanted tumor growth, inhibited pulmonary metastasis, and decreased lung tumor nodules in BALB/c nude mice bearing ErbB2 positive breast cancer cell MDA-MB-453 xenografts. The capacity for migration, adhesion, motility and invasion was also inhibited by BRACs in MDA-MB-453 cells in a concentration dependent manner, accompanied by decreased activity of a transfer promoting factor, urokinase-type plasminogen activator (u-PA). Conclusions: Together, our results indicated that BRACs possess anti-metastasis potential against ErbB2 positive human breast cancer cells in vivo and in vitro through inhibition of metastasis promoting molecules.

Objective: We hypothesized that DNA methylation of development-related genes may occur in endometrial cancer (EC)/ovarian cancer (OC) and may be detected in cervical scrapings. Methods: We tested methylation status by quantitative methylation-specific polymerase chain reaction for 14 genes in DNA pools of endometrial and OC tissues. Tissues of EC/normal endometrium, OC/normal ovary, were verified in training set using cervical scrapings of 10 EC/10 OC patients and 10 controls, and further validated in the testing set using independent cervical scrapings in 30 EC/30 OC patients and 30 controls. We generated cutoff values of methylation index (M-index) from cervical scrapings to distinguish between cancer patients and control. Sensitivity/specificity of DNA methylation biomarkers in detecting EC and OC was calculated. Results: Of 14 genes, 4 (PTGDR, HS3ST2, POU4F3, MAGI2) showed hypermethylation in EC and OC tissues, and were verified in training set. POU4F3 and MAGI2 exhibited hypermethylation in training set were validated in independent cases. The mean M-index of POU4F3 is 78.28 in EC and 20.36 in OC, which are higher than that in controls (6.59; p<0.001 and p=0.100, respectively), and that of MAGI2 is 246.0 in EC and 12.2 in OC, which is significantly higher that than in controls (2.85; p<0.001 and p=0.480, respectively). Sensitivity and specificity of POU4F3/MAGI2 were 83%–90% and 69%–75% for detection of EC, and 61% and 62%–69% for the detection of OC. Conclusion: The findings demonstrate the potential of EC/OC detection through testing for DNA methylation in cervical scrapings.

Comparative global immune-related gene profiling of somatic cells, human pluripotent stem cells and their derivatives: implication for human lymphocyte proliferation

Chia-Eng Wu,Chen-Wei Yu,Kai-Wei Chang,Wen-Hsi Chou,Chen-Yu Lu,Elisa Ghelfi,Fang-Chun Wu,Pey-Shynan Jan,Mei-Chi Huang,Patrick Allard,Shau-Ping Lin,Hong-Nerng Ho,Hsin-Fu Chen 생화학분자생물학회 2017 Experimental and molecular medicine Vol.49 No.-

Human pluripotent stem cells (hPSCs), including embryonic stem cells (ESCs) and induced PSCs (iPSCs), represent potentially unlimited cell sources for clinical applications. Previous studies have suggested that hPSCs may benefit from immune privilege and limited immunogenicity, as reflected by the reduced expression of major histocompatibility complex class-related molecules. Here we investigated the global immune-related gene expression profiles of human ESCs, hiPSCs and somatic cells and identified candidate immune-related genes that may alter their immunogenicity. The expression levels of global immune-related genes were determined by comparing undifferentiated and differentiated stem cells and three types of human somatic cells: dermal papilla cells, ovarian granulosa cells and foreskin fibroblast cells. We identified the differentially expressed genes CD24, GATA3, PROM1, THBS2, LY96, IFIT3, CXCR4, IL1R1, FGFR3, IDO1 and KDR, which overlapped with selected immune-related gene lists. In further analyses, mammalian target of rapamycin complex (mTOR) signaling was investigated in the differentiated stem cells following treatment with rapamycin and lentiviral transduction with specific short-hairpin RNAs. We found that the inhibition of mTOR signal pathways significantly downregulated the immunogenicity of differentiated stem cells. We also tested the immune responses induced in differentiated stem cells by mixed lymphocyte reactions. We found that CD24- and GATA3-deficient differentiated stem cells including neural lineage cells had limited abilities to activate human lymphocytes. By analyzing the transcriptome signature of immune-related genes, we observed a tendency of the hPSCs to differentiate toward an immune cell phenotype. Taken together, these data identify candidate immune-related genes that might constitute valuable targets for clinical applications.

Li-Min Xin,Lin Chen,Zhen-Peng Ji,Suo-Yuan Zhang,Jun Wang,Yan-Hong Liu,Da-Fang Chen,Fu-De Yang,Gang Wang,Yi-Ru Fang,Zheng Lu,Hai-Chen Yang,Jian Hu,Zhi-Yu Chen,Yi Huang,Jing Sun,Xiao-Ping Wang,Hui-Chun 대한정신약물학회 2015 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.13 No.3

Objective: To analyze the sociodemographic and clinical factors related to anxiety in patients with major depressive disorder (MDD). Methods: This study involved a secondary analysis of data obtained from the Diagnostic Assessment Service for People with Bipolar Disorders in China (DASP), which was initiated by the Chinese Society of Psychiatry (CSP) and conducted from September 1, 2010 to February 28, 2011. Based on the presence or absence of anxiety-related characteristics, 1,178 MDD patients were classified as suffering from anxious depression (n=915) or non-anxious depression (n=263), respectively. Results: Compared with the non-anxious group, the anxious-depression group had an older age at onset (t=−4.39, p<0.001), were older (t=−4.69, p<0.001), reported more lifetime depressive episodes (z=−3.24, p=0.001), were more likely to experience seasonal depressive episodes (χ2=6.896, p=0.009) and depressive episodes following stressful life events (χ2=59.350, p <0.001), and were more likely to have a family history of psychiatric disorders (χ2=6.091, p=0.014). Their positive and total scores on the Mood Disorder Questionnaire (MDQ) and the 32-item Hypomania Checklist (HCL-32) (p<0.05) were also lower. The logistic regression analysis indicated that age (odds ratio [OR]=1.03, p<0.001), a lower total MDQ score (OR=0.94, p=0.011), depressive episodes following stressful life events (OR=3.04, p<0.001), and seasonal depressive episodes (OR=1.75, p=0.039) were significantly associated with anxious depression. Conclusion: These findings indicate that older age, fewer subclinical bipolar features, an increased number of depressive episodes following stressful life events, and seasonal depressive episodes may be risk factors for anxiety-related characteristics in patients with MDD.
