Yi-rong Ying,Ying Ye 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.11

Through the establishment of the capital flight model of asymmetric evolutionary game, this paper focuses on the study of game relationship among perpetrators, perpetrator assistants and government, and analyzes the evolutionary stable process under different conditions by three-dimensional figures. This paper also analyzes and compares features between the two parties’ model and the three parties’ model, connecting the two kinds of evolutionary games and providing a theoretic basis for a better understanding of the mechanism of capital flight and motivation of all groups. The result shows that by making use of expectation, government can control the ESS of capital flight groups by adjusting relative benefits and punishment in different regulation modes. It can also expand the strategy space that is in favor of capital control through the adjustment. In the end, this paper will propose policy suggestions for the control of capital flight according to the research findings above.

Ying Li,Hong-Yan Liu,Ling-Na Shi,Yan-Rong Zhu,Ting-Feng Yi 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.101 No.-

In this work, the CeO2-decorated SrLi2Ti6O14 anode was successfully prepared through a solid-state process. The space-charge effect induced by the internal adsorption of ions on the CeO2 surface can easilyresult in a formation of an excellent conductive interfacial layer between CeO2 and SrLi2Ti6O14. The goodelectrical contact between CeO2 and SrLi2Ti6O14 offers more active sites for the electrolyte storage andredox reaction, and promotes the intercalation/deintercalation of lithium ions, and thus improves therate performance and cycle stability. Due to its unique structure and composition, the CeO2-decoratedSrLi2Ti6O14 composites exhibit high reversible capacities, good cycle performance and outstanding rateperformance. Especially, the CeO2 (5 wt%)-decorated SrLi2Ti6O14 anode shows the most excellent electrochemicalperformance, which delivers a large charge capacity of 121.3 mAh g 1 and a capacity retentionof 94.48% after 100 cycles at 0.5 A g 1. However, the corresponding charge capacity and capacity retentionof pristine SrLi2Ti6O14 are 100.5 mAh g 1 and 86.77%, respectively. The CeO2(5 wt%)-decoratedSrLi2Ti6O14 with enhanced rate capacity, cycle stability and structural stability is a potential electrodematerial candidate for Li-ion battery.

He, Jian-Rong,Xi, Jing,Ren, Ze-Fang,Qin, Han,Zhang, Ying,Zeng, Yi-Xin,Mo, Hao-Yuan,Jia, Wei-Hua Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.12

Purpose: Complement receptor 1 (CR1) is induced by Epstein-Barr virus (EBV) and may be a potential biomarker of nasopharyngeal carcinoma (NPC). We conducted the present study to evaluate the association of CR1 expression with clinicopathological features and prognosis of NPC. Methods: We enrolled 145 NPC patients and 110 controls. Expression levels of CR1 in peripheral blood mononuclear cells (PBMCs) were detected using quantitative real-time PCR and associations with clinicopathological features and prognosis were examined. Results: CR1 levels in the NPC group [3.54 (3.34, 3.79)] were slightly higher than those in the controls [3.33 (3.20, 3.47)] (P<0.001). Increased CR1 expression was associated with histology classification (type III vs. type II, P=0.002), advanced clinical stage (P=0.003), high T stage (P=0.017), and poor overall survival (HR, 4.89; 95% CI, 1.23-19.42; P=0.024). However, there were no statistically significant differences in CR1 expression among N or M stages. Conclusion: These findings indicate that CR1 expression in PBMCs may be a new biomarker for prognosis of NPC and a potential therapeutic target.

Zhang Qing,He Yi-Jing,Zhu Yu-Hang,Dai Min-Chen,Pan Man-Man,Wu Jia-Qi,Zhang Xian,Gu Ying-Er,Wang Fang-Fang,Xu Xiang-Rong,Qu Fan 한국한의학연구원 2020 Integrative Medicine Research Vol.9 No.3

Background: During the COVID-19 epidemic period, Traditional Chinese Medicine (TCM) course for international students of Medical Bachelor, Bachelor of Surgery (MBBS) program in Zhejiang University has shifted from traditional classroom to online environment. This study aimed to investigate MBBS international students’ perception on online TCM course, and to assess the online learning efficacy. Methods: A total of 84 MBBS international students attending course of “Basic Traditional Chinese Medicine” during 2020 academic years at Zhejiang University were enrolled in this study. A quantitative questionnaire was respectively completed before and after the TCM course using a pretest–post-test design. By means of two online learning platforms, Learning in ZJU and DingTalk, TCM course was broadcast in both live and archived format to students. Results: A total of 48 participants completed both baseline and follow-up questionnaires. The majority of participants preferred face-to-face classroom learning (26, 54.17% of total) when compared with online learning. Students felt that the course had brought in much benefits (mean 3.88, SD 0.87), and they were satisfied with the course content (mean 3.83, SD 0.95). Students’ TCM related knowledge and their behaviors of discussion and consulting were significantly improved by online TCM course (all P < 0.001). Students’ awareness of the necessity of TCM education and their feeling of difficulty in learning TCM were significantly strengthened (P = 0.042, 0.025, respectively). Conclusion: Online learning is a good alternative for TCM course of MBBS international students when classroom learning is suspended, whereas it cannot replace the need for onsite and face-to-face learning.

De novo assembly and transcriptome analysis of differentially expressed genes relevant to variegation in hawthorn flowers

Wei Ji,Wei Zhao,Rong‑Chen Liu,Xiao‑Bo Jiao,Kai Han,Zhong‑Yi Yang,Mei‑Ying Gao,Rui Ren,Xiu‑Juan Fan,Ming‑Xia Yang 한국식물생명공학회 2019 Plant biotechnology reports Vol.13 No.6

Flower color variegation has been observed in many plant species. However, pink flowers on the white-blooming hawthorn trees found by our group earlier have never been reported. To better understand the differentially expressed genes (DEGs) in variegated hawthorn flowers, white and pink flowers at different developmental stages (S1 and S2) underwent transcriptome sequencing separately. Approximately 34.28 Gb of high-quality data were obtained and assembled into 100,013 unigenes with an average length of 706.93 bp. These unigenes were further subjected to functional annotation and biochemical pathway analysis, and DEGs of two types of hawthorn flowers at different developmental stages were studied. Based on the enrichment analysis of DEGs, eight anthocyanin-modified enzyme genes or other enzyme genes that indirectly affect anthocyanin synthesis (5AT, 3GGT , and AI, β-Glu, two Aux/IAAs, two PODs), eight structural genes (UFGT, DFR, CHI, two F3Hs, and three PALs), and three transcription factors (one MYB and two bHLHs) were also identified. We randomly selected 15 genes, and the trends in the expression levels of these genes in the organs of white and pink flowers at different developmental stages were verified by quantitative real-time PCR. Mass sequence data obtained by RNA-seq of variegated hawthorn flowers provided basic sequence information and a unique opportunity to uncover the genetic mechanisms under-lying flower color variegation.

Aldehyde Volatiles Emitted in Succession from Mechanically Damaged Leaves of Poplar Cuttings

( Zeng Hui Hu ),( Ying Bai Shen ),( You Qing Luo ),( Fan Yi Shen ),( Hai Bo Gao ),( Rong Fu Gao ) 한국식물학회 2008 Journal of Plant Biology Vol.51 No.4

Plant aldehydes are volatiles necessary to defenses against environmental stress. To explore their emissions in response to wounding, we performed gas chromatography-mass spectrometry (GC-MS) on cuttings from poplar (Populus simonii×P. pyramidalis ``Opera 8277``) that were mechanically damaged to mimic herbivore attack. We detected 16 aldehydes, including 11 linear saturated aldehydes, 3 linear unsaturated aldehydes, and 2 non-linear aldehydes. Emissions of these aldehydes were clearly enhanced by such treatment, and exhibited a similar pattern of change, i.e., increasing in the first 2 h, then sharply decreasing before rising again at about 12 h. Two release peaks for these aldehydes were observed. Therefore, we propose two pathways for the mediation of aldehyde emissions following damage. The first peak may represent emissions from plant storage pools, whereas the second release peak might result from greater formation de novo through an activated synthesis pathway.

Ivantsov Ruslan D.,Lin Chun-Rong,Ivanova Oxana S.,Altunin Roman R.,Knyazev Yuriy V.,Molokeev Maxim S.,Zharkov Sergey M.,Chen Ying-Zhen,Lin En-Szu,Chen Bing-Yi,Shestakov Nikolai P.,Edelman Irina S. 한국물리학회 2021 Current Applied Physics Vol.25 No.-

Greigite (Fe3S4) nanoparticles (NPs) were fabricated by the thermal decomposition method using two different surfactants: oleylamine (OLA) and 1-hexadecylamine (HDA). In both cases, the synthesized NPs were characterized as the Fe3S4 nanocrystals with minor inclusions of Fe9S11 phase. FT-IR spectroscopy and thermogravimetric analysis allow concluding about OLA or HDA shells covering magnetic core of NPs. M¨ossbauer spectra has revealed deviations of iron ions distribution among crystal positions from that presented in literature for pure greigite. In accordance with these deviations, the pronounce changes are observed in the magnetic circular dichroism (MCD) spectra which manifest themselves as the spectrum shift to higher energies of electromagnetic waves and redistribution of the MCD maximum intensities. These effects are associated with a change in the density of electronic states in the samples due to the redistribution of iron ions between octahedral and tetrahedral positions in nanocrystals under the influence of surfactants.

Fei Xiao,Bing-xian Shao,Huan-rong Wu,Hui-ying Fu,Xiao-yuan Hou,Xin-dong Gao,Yi-qiang Zhan 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.2

Non-doped organic light-emitting diodes with saturated red emission were fabricated using 4-(2-(3,3-dicyanomethylene-5,5-dimethyl-1-cyclohexylidene)vinyl)phenyldi(1-naphthyl)amine (DNP-2CN) or 4-(2-(3,3-dicyanomethylene-5,5-dimethyl-1-cyclohexylidene)vinyl)phenyl(1-naphthyl)phe- nylamine (DPN-2CN) as the emitting layer. Different electron-transporting materials, tris(8-hydroxylquinoline) aluminum (Alq$_3$), 2,2',2''-(1,3,5-phenylene)tris[1-phenyl-1$H$-benzimidazole] (TPBI) and 2-(4-biphenyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole (PBD), were introduced into the devices for examining their energy level compatibility of DNP-2CN or DPN-2CN. The device with a structure of ITO/ NPB/ DNP-2CN/ BCP/ Alq$_3$/ LiF/ Al showed red emission with $\lambda_{max}$ at 670 nm (CIE coordinates: $x$ = 0.66, $y$ = 0.33) and a high luminance of 438 cd m$^{-2}$ at a driving voltage of 12 V. The device with a structure of ITO/ NPB/ DPN-2CN/ BCP/ Alq$_3$/ LiF/ Al showed a high brightness of 225 cd m$^{-2}$ at a driving voltage of 12 V with $\lambda_{max}$ at 674 nm (CIE coordinates: $x$ = 0.65, $y$ = 0.33).

Serum Peroxiredoxin3 is a Useful Biomarker for Early Diagnosis and Assessemnt of Prognosis of Hepatocellular Carcinoma in Chinese Patients

Shi, Liang,Wu, Li-Li,Yang, Jian-Rong,Chen, Xiao-Fei,Zhang, Yi,Chen, Zeng-Qiang,Liu, Cun-Li,Chi, Sheng-Ying,Zheng, Jia-Ying,Huang, Hai-Xia,Yu, Fu-Jun,Lin, Xiang-Yang Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.7

Background: Recently, peroxiredoxin3 (PRDX3) was identified as a novel molecular marker for the progression of hepatocellular carcinoma (HCC). However, its potential clinical application as a serum marker for the early diagnosis and prognosis of HCC has not been investigated. Methods: PRDX3, alpha-fetaprotein (AFP), and other biochemical parameters were measured in serum samples from 297 Chinese patients, including 96 with HCC, 98 with liver cirrhosis (LC), and 103 healthy controls (HCs). Correlations between serum PRDX3 expression and clinicopathological variables and the relationship between serum PRDX3 expression and prognosis were analyzed. Results: Serum PRDX3 was significantly higher in HCC patients than in the LC and HC groups. The sensitivity and specificity of serum PRDX3 for the diagnosis of HCC were 85.9% and 75.3%, respectively, at a cutoff of 153.26 ng/mL, and the area under the curve was 0.865. Moreover, serum PRDX3 expression was strongly associated with AFP level, tumor diameter, TNM stage, and portal vein invasion. Kaplan-Meier curve analysis revealed that HCC patients with high serum PRDX3 expression had a shorter median survival time than those with low PRDX3 expression. Moreover, serum PRDX3 expression was an independent risk factor for overall survival. The inverse correlation between serum PRDX3 and patient survival remained significant in patients with early-stage HCC and in those with normal serum AFP levels. Conclusions: Serum PRDX3 can be used as a noninvasive biomarker for the diagnosis and/or prognosis of HCC.

Dang, Ya-Mei,Huang, Gang,Chen, Yi-Rong,Dang, Zhong-Feng,Chen, Cheng,Liu, Feng-Lei,Guo, Ying-Fang,Xie, Xiao-Dong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.4

Aim: To investigate effects of sulforaphane on the BIU87 cell line and underlying mechanisms involving IGFBP-3. Methods: Both BIU87 and IGFBP-3-silenced BIU87 cells were treated with sulforaphane. Cell proliferation was detected by MTT assay. Cell cycle and apoptosis were determined via flow cytometry. Quantitative polymerase chain reaction and Western blotting were applied to analyze the expression of IGFBP-3 and NF-${\kappa}B$ at both mRNA and protein levels. Results: Sulforaphane (80 ${\mu}M$) treatment could inhibit cell proliferation, inducing apoptosis and cell cycle arrest at G2/M phase. All these effects could be antagonized by IGFBP-3 silencing. Furthermore, sulforaphane (80 ${\mu}M$) could down-regulate NF-${\kappa}B$ expression while elevating that of IGFBP-3. Conclusions: Sulforaphane could suppress the proliferation of BIU87 cells via enhancing IGFBP-3 expression, which negatively regulating the NF-${\kappa}B$ signaling pathway.
