Meta-analysis of Associations between Interleukin-17 Gene Polymorphisms and Risk of Gastric Cancer
Yu, Hui,Sun, Si,Liu, Fang,Xu, Qing-Hua Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.20
Background: Previous studies have indicated that single nucleotide polymorphisms (SNPs) of the interleukin-17 (IL-17) gene are associated with an increased risk of gastric cancer. However, the findings were inconsistent. Materials and Methods: To provide a more reliable estimation of the association between SNPs in the IL-17 gene and the susceptibility to gastric cancer, we searched PubMed, CNKI, and Wan Fang databases and selected finally six studies covering 2,366 cases and 3,205 controls to perform a meta-analysis. Results: Statistical analyses showed that an rs2275913 polymorphism within the IL-17A gene was significantly associated with an increased risk of gastric cancer using a generalized odds ratio (ORG, a model-free approach). Moreover, we also found that the 'A' allele carriers of IL-17A rs2275913 had a significant link with clinicopathological features. However, no significant positive signals were observed in the association analysis of the rs3748067 and rs763780 polymorphisms with the risk of gastric cancer in IL-17A and IL-17F, respectively. Conclusions: Despite some limitations, the present meta-analysis provided a more precise estimation of the relationship between the IL-17 gene SNPs and gastric cancer risk compared with individual studies.
Yu Hui,Sary Schroeder 아시아음악학회 2017 Asian Musicology Vol.27 No.-
This study aims at the examination of interactive relationships between globalized “local music” and a “global audience,” on the example of Chinese music as to be found on Youtube. Distribution and popularity patterns of Chinese music videos are studied, as well as their public perception. The study is an attempt of pushing forward the boundaries of both ethnomusicology and internet research in the 21st century digital age. Since systematic research approaches to global audiences from an musicological perspective have been undertaken rarely with regard to internet music, this study can be regarded as an methodological suggestion, which might be taken further and adopted into other contexts.
Renewable Low-viscosity Dielectrics Based on Vegetable Oil Methyl Esters
Yu, Hui,Yu, Ping,Luo, Yunbai The Korean Institute of Electrical Engineers 2017 Journal of Electrical Engineering & Technology Vol.12 No.2
Vegetable oil dielectrics have been used in transformers as green alternatives to mineral insulating oils for about twenty years, because of their advantages of non-toxic, biodegradability, and renewability. However, the viscosity of vegetable oils is more than 3 times of mineral oils, which means a poor heat dissipation capacity. To get low-viscosity dielectrics, transesterification and purification were performed to prepare vegetable oil methyl esters in this study. Electrical and physical properties were determined to investigate their potential as dielectrics. The results showed that the methyl ester products had good dielectric strengths, high water saturation and enough fire resistance. The viscosities (at $40^{\circ}C$) were 0.2 times less than FR3 fluid, and 0.7 times less than mineral oil, which indicated superior cooling capacity as we expected. With the assistance of 0.5 wt% pour point depressants, canola oil methyl ester exhibited the lowest pour point ($-26^{\circ}C$) among the products which was lower than FR3 fluid ($-21^{\circ}C$) and 25# mineral oil ($-23^{\circ}C$). Thus, canola oil methyl ester was the best candidate as a low-viscosity vegetable oil-based dielectric. The low-viscosity fluid could extend the service life of transformers by its better cooling capacity compared with nature ester dielectrics.
Depression and Survival in Chinese Patients with Gastric Cancer: A Prospective Study
Yu, Hui,Wang, Yaoxian,Ge, Xin,Wu, Xiaoke,Mao, Xiaoqin Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.1
Aim: Depression is thought to be a predictor of poor survival among cancer patients. In our study, we aimed to investigate the association between depression and survival in patients with gastric cancer. Methods: The subjects were a total of 300 patients aged 20-75 years who had histological confirmed diagnosis of gastric cancer from January 2004 to May 2006. Three months after patients diagnosis, depression was scored using by the Depression Status Inventory (DSI) designed by Willian WK Zung. The follow-up period consisted of a total of 13,643 person-months. A Cox's regression analysis was used to assess the association between depression and survival. Results: The percentage of subjects with depression according to the DSI depression criteria was 31%. Tumor stage and treatment methods were significantly associated with depression of patients. Age (60 years or older), annual income, tumor stage, lymph nodes metastasis and treatment were significantly associated with increased hazard ratio (HR) for gastric cancer survival. The adjusted HR for mortality risk in gastric cancer patients with depression tended to be high (HR=3.34, 95% CI=1.23-5.49) and a significant trend was found (P<0.05). Conclusion: The data obtained in this prospective study in Chinese support the hypothesis that depression is associated with poor survival among gastric cancer patients. Further studies with a large sample and longer term follow-up period are needed.
Fe(II)-Anchored Cotton Fabric for Heterogeneous Fenton Degradation of Rhodamine B Dye
Yuhui Yang,Hongbin Chen,Ruquan Zhang,Jingjing Huang,Zhikui Bai,Shili Xiao 한국섬유공학회 2022 Fibers and polymers Vol.23 No.10
The ferric ions sludge produced during pollutants degradation was an obstacle for large scale application of Fentonoxidation technology. Herein, we reported a facile method using 2,2,6,6-tetramethylpiperidine-1-oxygen radical (TEMPO)-oxidized cotton fabric as a substrate for anchoring Fe(II) ions to produce Fe(II)-anchored cotton fabric. The formation ofFe(II)-anchored cotton fabric was confirmed using EDS analysis and FTIR measurement. Bath experiments indicated thatFe(II)-anchored cotton fabric could Fenton oxidize rhodamine B (RhB) dye in a high efficient rate (95.9 %) within 60 minwithout second pollution. Fe(II)-anchored cotton could be reused without any physical/chemical treatment and itsdecolorization efficiency was retained at 89.9 % even after the third cycle. Moreover, the decolorization behavior of Fe(II)-anchored cotton fabric for the RhB solution was affected by H2O2 dosage, Fe(II) ion content, and inorganic salts. Kineticstudy indicated that the RhB decolorization process fits a pseudo-first order well and the sorption isotherm assessmentrevealed that the reactive sorption of RhB dye on Fe(II)-anchored cotton fabric fits the Freundlich model.
An Improved BER-Optimal Relay Selection Scheme for Decode-and-Forward Cooperative Networks
Yuhui Han,Mingji Yang,Aili Wang 보안공학연구지원센터 2015 International Journal of Future Generation Communi Vol.8 No.1
We are concerned with the relay selection in a decode-and-forward cooperative network to minimize the bit error rate (BER) in a radio cell. This problem can be solved using maximum weighted (MW) matching algorithm, greedy matching algorithm or worst-link-first (WLF) matching algorithm. Among the algorithms, WLF matching algorithm has achieved much attention for its being less complex while the achieved performance is high. In order to further reduce the computational complexity, we propose an improved WLF relay selection scheme, in which relays are selected according to instantaneous channel state information (CSI) and a cooperative threshold is set up to eliminate some unsatisfying candidate relays from the set of alternative candidate relays and thus reduce the amount of calculation. Theory analysis and simulation results both show that the improved WLF relay selection scheme proposed can be easily implemented and achieve almost the same BER performance as that of WLF scheme while the computational complexity is much lower.
On a Waring-Goldbach problem involving squares, cubes and biquadrates
Yuhui Liu 대한수학회 2018 대한수학회보 Vol.55 No.6
Let $P_r$ denote an almost-prime with at most $r$ prime factors, counted according to multiplicity. In this paper, it is proved that for every sufficiently large even integer $N$, the equation \begin{gather*} N=x^2+p_1^2+p_2^3+p_3^3+p_4^4+p_5^4 \end{gather*} is solvable with $x$ being an almost-prime $P_{4}$ and the other variables primes. This result constitutes an improvement upon that of L\"{u} \cite{7}.
Exploring the Boundary Region for Attribute Reduction in Inconsistent Decision Tables
Yuhui Chang,Jin Qian 보안공학연구지원센터 2016 International Journal of Database Theory and Appli Vol.9 No.10
Attribute reduction is one of the key issues for data preprocess in data mining. Many heuristic attribute reduction algorithms based on discernibility matrix have been proposed for inconsistent decision tables. However, these methods are usually computationally time-consuming. To address this issue, the derived consistent decision tables are defined for different definitions of relative reducts. The computations for different reducts of the original inconsistent decision tables are converted into the computations for their corresponding reducts of the derived consistent datasets. The relationships among different core sets and attribute reducts are further discussed. The relative discernibility object pair and the more optimal relative discernibility degree from view of the boundary region are designed to accelerate the attribute reduction process. An efficient attribute reduction framework using relative discernibility degree is proposed for large datasets. Experimental results show that our attribute reduction algorithms are effective and feasible for large inconsistent datasets.
