儒家政治思想是中國傳統政治思想的主流, 對于中國社會的政治、經濟、文化等諸方面都産生了極大的影響。本文論述了20世紀百年儒家政治思想的硏究歷程, 以期對未來的儒家政治思想硏究提供一個較爲系統的理論框架。 The present paper discussed the study course of the Confucian political thoughts in one hundred years of the 20th century .Maybe it can provide a systemic theory frame for the future study of the Confucian political thoughts. From 1900 to 2000,Chinese academia’s study on the Confucian political thoughts had gone through four stages as follows in this one hundred years. At the first stage(1900-1919),the newly bourgeois of reform school talked about the politics according to the lection, but the revolutionary school criticized the confucian political thoughts. At the second stage(1919-1949), the dominating social and political ideology is to criticize and denounce the Confucian. At the third stage (1949-1976), Maxism is becoming the guidance thought on the Mainland China. The Confucian political thoughts got more and more criticism and led to the Great Cultural Revolution finally. It suffered entirely denial. However, it had rised in Taiwan, HongKong and even overseas areas. At the last stage(from 1976 to this day), the Confucism is enjoying a flourish renaissance. [Article in Chinese]

Zinc finger-containing transcription factors are the largest single family of transcriptional regulators in mammals, which play an essential role in cell differentiation, cell proliferation, apoptosis, and neoplastic transformation. Here we have cloned a novel KRAB-related zinc finger gene, ZNF424, encoding a protein of 555aa. ZNF424 gene consisted of 4 exons and 3 introns, and mapped to chromosome 19p13.3. ZNF424 gene was ubiquitously expressed in human embryo tissues by Northern blot analysis. ZNF424 is conserved across species in evolution. Using a GFP-labeled ZNF424 protein, we demonstrate that ZNF424 localizes mostly in the nucleus. Transcriptional activity assays shows ZNF424 suppresses transcriptional activity of L8G5-luciferase. Overexpression of ZNF424 in HEK- 293 cells inhibited the transcriptional activity of NFAT and p21, which may be silenced by siRNA. The results suggest that ZNF424 protein may act as a transcriptional repressor that suppresses NFAT and p21 pathway to mediate cellular functions. [BMB reports 2010; 43(3): 212-218]

Construction of antibacterial layer on polyvinylchloride three-channel hollow fiber membranes

Mei-Sheng Li,Ming-Xing Wang,Fei-Yue Wu,Xiao-Zhong Chu 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.39 No.-

The inner surfaces of polyvinylchloride (PVC) three-channel hollow fiber membranes were successfullymodified with poly(methacryloxylethyl benzyl dimethyl ammonium chloride) (PDMAE-BC) in a modulescale via remote plasma-induced surface graft polymerization method. After grafting a PDMAE-BC layer,the PVC surface hydrophilicity was improved greatly due to the introduction of large amounts of oxygenand nitrogen containing polar groups onto polymer backbone. This hydrophilicity improvement directlyleaded to a high pure water flux and a good antifouling property for the obtained PVC-PDMAE-BCmembrane module. Meanwhile, the inner surface morphologies of modified PVC membranes changedslightly and the surface structures were maintained well. The tensile strength, though deceased slightlyat the remote plasma-treated stage, showed no significant change during overall grafting process. Theobtained PVC-PDMAE-BC membrane module exhibited highly effective and stable antibacterialactivities against Escherichia coli. The antibacterial efficacy of PVC-PDMAE-BC membrane module withonly 6 fibers can achieve about 96.3% and could be further enhanced by increasing the packing density. The antibacterial membrane module may have great potential applications in actual wastewatertreatment and membrane bioreactor (MBR).

Wang, Bang-Yan,Yang, Xue-Qiong,Hu, Ming,Shi, Li-Jiao,Yin, Hai-Yue,Wu, Ya-Mei,Yang, Ya-Bin,Zhou, Hao,Ding, Zhong-Tao The Korean Society of Ginseng 2020 Journal of Ginseng Research Vol.44 No.6

Background: Fermentation has been shown to improve the biological properties of plants and herbs. Specifically, fermentation causes decomposition and/or biotransformation of active metabolites into high-value products. Polyacetylenes are a class of polyketides with a pleiotropic profile of bioactivity. Methods: Column chromatography was used to isolate compounds, and extensive NMR experiments were used to determine their structures. The transformation of polyacetylene in red ginseng (RG) and the production of cazaldehyde B induced by the extract of RG were identified by TLC and HPLC analyses. Results: A new metabolite was isolated from RG fermented by Chaetomium globosum, and this new metabolite can be obtained by the biotransformation of polyacetylene in RG. Panaxytriol was found to exhibit the highest antifungal activity against C. globosum compared with other major ingredients in RG. The fungus C. globosum cultured in RG extract can metabolize panaxytriol to Metabolite A to survive, with no antifungal activity against itself. Metabolites A and B showed obvious inhibition against NO production, with ratios of 42.75 ± 1.60 and 63.95 ± 1.45% at 50 µM, respectively. A higher inhibitory rate on NO production was observed for Metabolite B than for a positive drug. Conclusion: Metabolite A is a rare example of natural polyacetylene biotransformation by microbial fermentation. This biotransformation only occurred in fermented RG. The extract of RG also stimulated the production of a new natural product, cazaldehyde B, from C. globosum. The lactone in Metabolite A can decrease the cytotoxicity, which was deemed to be the intrinsic activity of polyacetylene in ginseng.

A novel human KRAB-related zinc finger gene ZNF425 inhibits mitogen-activated protein kinase signaling pathway

( Yue Qun Wang ),( Xiang Li Ye ),( Jun Mei Zhou ),( Yong Qi Wan ),( Hua Ping Xie ),( Yun Deng ),( Yan Yan ),( Yong Qing Li ),( Xiong Wei Fan ),( Wu Zhou Yuan ),( Xiao Yang Mo ),( Xiu Shan Wu ) 생화학분자생물학회(구 한국생화학분자생물학회) 2011 BMB Reports Vol.44 No.1

Zinc finger (ZNF) proteins play a critical role in cell growth, proliferation, apoptosis, and intracellular signal transduction. In this paper, we cloned and characterized a novel human KRAB-related zinc finger gene, ZNF425, which encodes a protein of 752 amino acids. ZNF425 is strongly expressed in the three month old human embryos and then is almost undetectable in six month old embryos and in adult tissues. An EGFP-ZNF425 fusion protein can be found in both the nucleus and the cytoplasm. ZNF425 appears to act as a transcription repressor. Over-expression of ZNF425 inhibits the transcriptional activities of SRE, AP-1, and SRF. Deletion analysis indicates that the C2H2 domain is the main region responsible for the repression. Our results suggest that the ZNF425 gene is a new transcriptional inhibitor that functions in the MAPK signaling pathway. [BMB reports 2011; 44(1): 58-63]

Simplified method for prediction of elastic-plastic buckling strength of web-post panels in castellated steel beams

Mei Liu,Kangrui Guo,Peijun Wang,Chao Lou,Yue Zhang 국제구조공학회 2017 Steel and Composite Structures, An International J Vol.25 No.6

Elastic-plastic shear buckling behaviors of the web-post in a Castellated Steel Beam (CSB) with hexagonal web openings under vertical shear force were investigated further using Finite Element Model (FEM) based on a sub-model, which took the upper part of the web-post under horizontal shear force to represent the whole web-post under vertical shear force. A simplified design method for the web-post elastic-plastic shear buckling strength was proposed based on simulation results of the sub-model. Proper boundary conditions were applied to the sub-model to assure that its behaviors were identical to those of the whole web-post. The equation to calculate the thin plate elastic shear buckling strength was adopted as the basic form to build the design equation for elastic-plastic buckling strength of the sub-model. Parameters that might affect the elastic-plastic shear buckling strength of the whole web-post were studied. After obtaining the vertical shear buckling strength of a sub-model through FEM, the shear buckling coefficient k can be obtained through the back analysis. A practical calculation method for k was proposed through curving fitting the parameter study results. The elastic-plastic shear buckling strength of the web-post calculated using the proposed shear buckling coefficient k agreed well with that obtained from the FEM and test results. And it was more precise than those obtained from EC3 based on the strut model.

G Protein–Coupled Receptor 30 Mediates the Anticancer Effects Induced by Eicosapentaenoic Acid in Ovarian Cancer Cells

Yue Zhao,Meng-Fei Zhao,Mei-Lin Yang,Tian-Yu Wu,Cong-Jian Xu,Jing-Mei Wang,Chao-Jun Li,Xi Li 대한암학회 2020 Cancer Research and Treatment Vol.52 No.3

Purpose: While numerous epidemiological studies have indicated that omega-3 polyunsaturated fatty acids have anticancer properties in various cancers, the effects and mechanisms of eicosapentaenoic acid (EPA) in ovarian cancer cell growth are poorly understood. Materials and Methods: ES2 ovarian clear cell carcinoma cells and SKOV3 adenocarcinoma cells were treated with palmitic acid or EPA, followed by flow cytometry and cell counting to measure apoptosis and proliferation, respectively. A modified protein lipid overlay assay was used to further verify whether EPA was a ligand of G protein–coupled receptor 30 (GPR30) in ES2 cells. The levels of apoptosis-related genes, phosphorylated AKT, and phosphorylated ERK1/2 were detected to explore the underlying mechanism. Finally, inhibitory effect of EPA on tumor growth via GPR30 was determined in vitro and in vivo. Results: EPA suppressed ES2 ovarian clear cell carcinoma cells growth via GPR30, a novel EPA receptor, by inducing apoptosis. As a ligand of GPR30, EPA activated the GPR30-cAMP– protein kinase A signaling pathway. When GPR30 was suppressed by siRNA or its inhibitor G15, the antiproliferative action of EPA was impaired. Furthermore, EPA inhibited tumor growth by blocking the activation of AKT and ERK. In the mouse xenograft model, EPA decreased tumor volume and weight through GPR30 by blocking tumor cell proliferation. Conclusion: These results confirm that EPA is a tumor suppressor in human ovarian clear cell carcinoma cells and functions through a novel fatty acid receptor, GPR30, indicating a mechanistic linkage between omega-3 fatty acids and cancers.

Cheng Mei-Fang,Guo Yue Leon,Yen Ruoh-Fang,Wu Yen-Wen,Wang Hsiu-Po 대한영상의학회 2023 Korean Journal of Radiology Vol.24 No.6

Objective: To investigate whether the levels of inflammation detected by 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) can predict disease relapse in immunoglobulin G4-related disease (IgG4-RD) patients receiving standard induction steroid therapy. Materials and Methods: This prospective study analyzed pretherapy FDG PET/CT images from 48 patients (mean age, 63 ± 12.9 years; 45 males and 3 females) diagnosed with IgG4-RD between September 2008 and February 2018, who subsequently received standard induction steroid therapy as the first-line treatment. Multivariable Cox proportional hazards models were used to identify the potential prognostic factors associated with relapse-free survival (RFS). Results: The median follow-up time for the entire cohort was 1913 days (interquartile range [IQR], 803–2929 days). Relapse occurred in 81.3% (39/48) patients during the follow-up period. The median time to relapse was 210 days (IQR, 140–308 days) after completion of standardized induction steroid therapy. Among the 17 parameters analyzed, Cox proportional hazard analysis identified whole-body total lesion glycolysis (WTLG) > 600 on FDG-PET as an independent risk factor for disease relapse (median RFS, 175 vs. 308 days; adjusted hazard ratio, 2.196 [95% confidence interval: 1.080–4.374]; P = 0.030). Conclusion: WTLG on pretherapy FDG PET/CT was the only significant factor associated with RFS in IgG-RD patients receiving standard steroid induction therapy.

Structure-based design, structure–activity relationship analysis, and antitumor activity of diaryl ether derivatives

Shao-Mei Yang,Fu-Nan Li,Zhi-Ning Huang,Zhong-Shi Zhou,Jin Hou,Man-Yi Zheng,Li-Juan Wang,Yu Jiang,Xin-Yi Zhou,Qiu-Yue Chen,Shan-Hua Li 대한약학회 2015 Archives of Pharmacal Research Vol.38 No.10

To identify novel therapeutic agents to treatcancer, we synthesized a series of diaryl ether derivatives. Structure–activity relationship studies revealed that thepresence of a chlorine or hydroxyl at the para-position onthe phenyl ring (5h or 5k) significantly enhanced antitumoractivity. Compound 5h had stronger growth inhibitory activityin HepG2, A549, and HT-29 cells than compound 5k,with IC50 values of 2.57, 5.48, and 30.04 lM, respectively. Compound 5h also inhibited the growth of other cells lines,including Hep3B, PLC/PRF5, SMMC-7721, HeLa, andA375, with IC50 values of 2.76, 4.26, 29.66, 18.86, and10.21 lM, respectively. The antitumor activity of compound5h was confirmed by a colony forming assay. Further,our results indicated that the antitumor activity ofcompound 5h may be mediated by enhancing expression ofp21 and cl-caspase3, and leading to apoptosis of cancercells.
