      • Polymorphic Variation of Inflammation-related Genes and Risk of Non-Hodgkin Lymphoma for Uygur and Han Chinese in Xinjiang

        Gu, Xia,Shen, Yan,Fu, Ling,Zuo, Hong-Yun,Yasen, Halida,He, Ping,Guo, Xin-Hong,Shi, Yu-Wei,Yusufu, Muhabaiti Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.21

        Polymorphisms of inflammation-related genes have been found to be associated with non-Hodgkin lymphoma (NHL) or some of its subtypes, but only a few relevant data have been reported in China. In this study, the Snapshot method was used to assess genetic variation; a total of 14 single nucleotide polymorphisms (SNPs) for 6 inflammatory factors in 157 NHL cases (64 Uygur ethnic subjects, 93 Han Chinese) and 435 controls (231 Uygur and 204 Han Chinese) were studied from the Xinjiang province of China. Haplotype distribution was estimated using PHASE 2.3 software. Statistical differences in the genotype and haplotype frequencies between case and control groups were also considered and estimated. For the Han population, the geneotype distributions for TNF-${\alpha}rs1800629$, TNF-${\alpha}rs1800630$, IL-6 rs1800795, IL-6 rs1800797, NF-KB1 rs1585215 and TLR-4 rs4986790 showed significant differences between the case and control groups (p<0.05). The TNF-${\alpha}$ gene frequencies of ACG and CCA haplotypes in the cases were higher than in the controls (OR=2.45, 95% CI: 1.55-3.89, p=0.0002, OR=2.53, 95% CI: 1.10-5.80, p=0.029, respectively), and the same findings were detected for TNF-${\beta}$ gene CA haplotype (OR=1.87, 95% CI: 1.21-2.90, p=0.0054). However, for the Uygur population, no such significant differences were detected within the gene-type distribution of the 14 SNPs. The TNF-${\alpha}$ gene frequency of the CCA haplotype between the two groups (OR=1.98, 95% CI: 1.11-3.51, p=0.021) revealed a statistically significant difference. Our results showed that polymorphic variations of inflammation-related genes could be important to the NHL etiology of the Han population, and that these may only have limited influence on the Uygur population.

        Percutaneous Osteoplasty for the Management of a Femoral Head Metastasis: a Case Report

        Wei-Guo Wang,Chun-Gen Wu,Yi-Feng Gu,Ming-Hua Li 대한영상의학회 2009 Korean Journal of Radiology Vol.10 No.6

        Percutaneous osteoplasty (POP) as a technical extension of percutaneous vertebroplasty (PVP) has been used to treat malignant disease that affects the skeletal system. POP has demonstrated good outcome for pain relief and functional improvement. Few studies have reported on the efficiency of POP to treat malignancies located in the femoral head. We designed a pilot study with the use of POP to treat intractable pain caused by a femoral head metastatic tumor in a 43-year-old man. During the follow-up period, the patient experienced sustained pain relief and improvement of quality of life that persisted for more than three months.

        Security Analysis of the PHOTON Lightweight Cryptosystem in the Wireless Body Area Network

        ( Wei Li ),( Linfeng Liao ),( Dawu Gu ),( Chenyu Ge ),( Zhiyong Gao ),( Zhihong Zhou ),( Zheng Guo ),( Ya Liu ),( Zhiqiang Liu ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.1

        With the advancement and deployment of wireless communication techniques, wireless body area network (WBAN) has emerged as a promising approach for e-healthcare that collects the data of vital body parameters and movements for sensing and communicating wearable or implantable healthful related information. In order to avoid any possible rancorous attacks and resource abuse, employing lightweight ciphers is most effective to implement encryption, decryption, message authentication and digital signature for security of WBAN. As a typical lightweight cryptosystem with an extended sponge function framework, the PHOTON family is flexible to provide security for the RFID and other highly-constrained devices. In this paper, we propose a differential fault analysis to break three flavors of the PHOTON family successfully. The mathematical analysis and simulating experimental results show that 33, 69 and 86 random faults in average are required to recover each message input for PHOTON-80 /20/16, PHOTON-160/36/36 and PHOTON-224/32/32, respectively. It is the first result of breaking PHOTON with the differential fault analysis. It provides a new reference for the security analysis of the same structure of the lightweight hash functions in the WBAN.

        Effects of graphite additives in electrolytes on the microstructure and corrosion resistance of Alumina PEO coatings

        Guo-Hua Lv,Huan Chen,Wei-Chao Gu,Wen-Ran Feng,Li Li,Er-Wu Niu,Xian-Hui Zhang,Si-Ze Yang 한국물리학회 2009 Current Applied Physics Vol.9 No.3

        In the present work, graphite grains of different sizes were added into the electrolyte to prepare ceramic coatings on aluminum by plasma electrolytic oxidation (PEO). Scanning electron microscopy (SEM) coupled with an energy dispersive X-ray analysis system (EDX), Raman spectroscopy and X-ray diffractometer (XRD) were used to characterize the coatings. A three-electrode system was used to evaluate the corrosion performances of the coatings in a 3.5 wt.% NaCl solution. It was found that the morphology and corrosion performance of the coatings were significantly influenced by the size of the graphite grains. Compared with bigger graphite grains, finer ones were involved in the oxidation process and embedded within the ceramic coatings, which made the coatings less porous and more compact. Thus, the corrosion resistance of the coatings with embedded graphite grains was greatly improved.

        Experimental research and molecular dynamics simulation on thermal properties of capric acid/ethylene-vinyl/graphene composite phase change materials

        Yue Gu,Linhua Jiang,Weizhun Jin,Zhenhua Wei,Xing Liu,Mingzhi Guo,Kailun Xia,Lei Chen 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.99 No.-

        In this paper, a new series of phase change materials (PCMs) composed of capric acid/ethylene-vinylacetate/graphene (CA/EVA/GR) were prepared and thermal properties were investigated using moleculardynamics simulation. The composite PCMs were characterized by Fourier transform infraredspectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanningcalorimetry (DSC) and thermal conductivity measurement. FT-IR, XRD and SEM results manifest that CAcan be successfully wrapped by EVA and GR additives, and there is no chemical reaction between CA, EVAand GR. DSC results indicate that adding GR into CA/EVA can result in composite PCMs maintain the highlatent heat, while too much GR will cause a significant reduction in latent heat. Thermal conductivityobtained from experimental tests reveal that GR can gradually enhance the thermal conductivity of CA/EVA with increasing dosage of GR. The experimental results of thermal conductivity fall close to that ofmolecular dynamics (MD) simulation at GR dosages below 1.8 wt%, but the experimental results present atrend which is contrary to MD simulation at higher GR dosages. The mean square displacement (MSD)results manifest that composite PCMs containing 1.8 wt% GR has the highest diffusion coefficient, whilehigher GR dosage will reduce the diffusion coefficient gradually.

        Effect of Lactobacillus rhamnosus hsryfm 1301 on the Gut Microbiota and Lipid Metabolism in Rats Fed a High-Fat Diet

        ( Da Wei Chen ),( Zhen Quan Yang ),( Xia Chen ),( Yu Jun Huang ),( Bo Xing Yin ),( Fei Xiang Guo ),( Hai Qing Zhao ),( Jia Di Huang ),( Yun Wu ),( Rui Xia Gu ) 한국미생물 · 생명공학회 2015 Journal of microbiology and biotechnology Vol.25 No.5

        Accumulating evidence indicates that lactic acid bacteria could improve host physiology and lipid metabolism. To investigate the effect of the gut microbiota on host lipid metabolism, a hyperlipidemic rat model was established by feeding rats a high-fat diet for 28 days, and the gut microbiota of the rats was analyzed using real-time PCR before and after administration of Lactobacillus rhamnosus hsryfm 1301 and its fermented milk for 28 days. The findings showed that the Lactobacillus spp., Bifidobacterium spp., Bacteroides spp., and Enterococcus spp. content in the hyperlipidemic rats gut was increased significantly (p < 0.05), while the Clostridium leptum and Enterobacter spp. content was decreased significantly after intervening with L. rhamnosus hrsyfm 1301 and its fermented milk for 28 days (p < 0.05). Furthermore, the lipid levels of the serum and the liver were decreased significantly (p < 0.05) and the fecal water content was increased significantly (p < 0.05) in the hyperlipidemic rats after the intervention, and hepatocyte fatty degeneration of liver tissues was also prevented. A positive correlation was observed between the Clostridium leptum content and the level of serum cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein, and a negative correlation was observed between the Enterobacter spp. content and the Lactobacillus spp. and Bifidobacterium spp. content in the hyperlipidemic rats gut. These results suggest that the gut microbiota and lipid metabolism of hyperlipidemic rats could be improved by supplementation with L. rhamnosus hsryfm 1301 and its fermented milk.

        Dong, Wei-Min,Cao, Xiang-Shan,Wang, Biao,Lin, Yun,Hua, Xiao-Ying,Qiu, Guo-Qiang,Gu, Wei-Ying,Xie, Xiao-Bao Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

        Objective: Explore the feasibility of allo-hemopietic stem cell transplants in treating patients with B cell acute lymphocytic leukemia. Methods: Between september 2006 and February 2011, fifteen patients with B cell acute lymphocytic leukemia (ALL) were treated by allo-hemopietic stem cell transplants (HSCT). Stem cell sources were peripheral blood. Six patients were conditioned by busulfan (BU) and cyclophosphamide (CY) and nine patients were conditioned with TBI and cyclophosphamide (CY). Graft versus host disease (GVHD) prophylaxis regimen consisted of cyclosporine A (CSA), methotrex ate (MTX) and mycophenolatemofetil (MMF). Results: Patients received a median of $7.98{\times}10^8{\cdot}kg^{-1}$ ($5.36-12.30{\times}10^8{\cdot}kg^{-1}$) mononuclear cells (MNC). The median time of ANC> $0.5{\times}10^9/L$ was day 12 (10-15), and PLT> $20.0{\times}10^9/L$ was day 13 (11-16). Extensive acute GVHD occurred in 6 (40.0%) patients, and extensive chronic GVHD was recorded in 6 (40.0%) patients. Nine patients were alive after 2.5-65 months follow-up. Conclusion: Allogeneic stem cell transplant could be effective in treating patients with B cell acute lymphocytic leukemia.

        Structural and Ferromagnetic Properties SnO2/TiO2 Nanotubes Obtained by Electrospinning

        JIAN-GUO ZHAO,Yan-Hong Gu,Hong Jia,Zhuan Hu,Shuqian Qiao,Mengjing Jin,Panting Ge,WEI-YING ZHANG,Shijiang Liu,ZHAO-JUN LIU 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2017 NANO Vol.12 No.10

        SnO2/TiO2 (Sn/Ti = 5/1) nanotubes were prepared by the electrospinning method. The morphology was characterized by scanning electron microscope (SEM) and transmission electron microscope (TEM). The results showed that the inner diameter of prepared materials was about 100 nm and the wall thickness was about 10 nm. The results of X-ray diffraction (XRD) and high resolution transmission electron microscope (HRTEM) showed that SnO2/TiO2 nanotubes had a mixed phase of SnO2 rutile and TiO2 anatase structures and no impurity phases. The magnetic properties of the SnO2/TiO2 nanotubes were characterized by a superconducting quantum interferometer (SQUID). The results indicated that the samples exhibited room temperature ferromagnetism which may be attributed to the interface between TiO2 and SnO2 phases.

        Iterative Learning Control for a Class of Mixed Hyperbolic-parabolic Distributed Parameter Systems

        Qin Fu,Wei-Guo Gu,Pan-Pan Gu,Jian-Rong Wu 제어·로봇·시스템학회 2016 International Journal of Control, Automation, and Vol.14 No.6

        This paper deals with the problem of iterative learning control algorithm for a class of mixed distributedparameter systems. Here, the considered distributed parameter systems are composed of mixed hyperbolicparabolicpartial differential equations. The domain of the system is divided into two parts in which the system ishyperbolic and parabolic, respectively, with transmission conditions at the interface. According to the characteristicsof the systems, iterative learning control laws are proposed for such mixed hyperbolic-parabolic distributedparameter systems based on P-type learning scheme. Using the contraction mapping method, it is shown that thescheme can guarantee the output tracking errors on L2 space converge along the iteration axis. A simulation exampleillustrates the effectiveness of the proposed method.
