| 3 | Cancer stem cell markers correlate with early recurrence and survival in hepatocellular carcinoma显示文摘AIM:To investigate whether expression of cancer stem cell(CSC)markers is associated with recurrence and survival in hepatocellular carcinoma(HCC)patients.METHODS:A consecutive series of 90 HCC patients who underwent curative hepatectomy between April2007 and April 2009 were analyzed.Of the 90 patients,38(42%)experienced recurrence within two years of surgery.To adjust for baseline differences between this early recurrence group and the other patients,propensity-score matching was used to generate 25 pairs of patients.Immunohistochemistry was used to compare expression of CD133,CD90,and epithelial cell adhesion molecule(EpCAM)in liver tissues from propensity score-matched patients and from 10 healthy adults.Associations of the three markers with HCC,clinicopathological characteristics,early recurrence,and survival time were explored.RESULTS:The expression of all three CSC markers was significantly higher in HCC tissue than in healthy liver tissue(P<0.001 for all).Among the HCC clinicopathology characteristics examined,the absence of tumor capsule was associated with CD133 expression(P=0.005);higher histopathology grade and larger tumor size were associated with CD90 expression(P=0.010 and 0.034,respectively);and elevated serum alpha-fetoprotein levels were associated with EpCAM expression(P=0.021).Expression of CD90 and EpCAM was significantly higher in the early recurrence group than in other patients(P=0.001 and 0.045,respectively),whereas CD133 expression was not significantly different between the two groups(P=0.440).Multivariate analysis identified only CD90 expression as significantly associated with early recurrence.Log-rank analysis identified expression of both CD90 and EpCAM as significantly associated with survival time of HCC patients.Cox regression identified EpCAM expression as an independent predictor of survival time.CONCLUSION:Expression of CD133,CD90,and EpCAM CSC markers may be linked to HCC tumor onset and/or progression.In addition,EpCAM expression is associated with shorter survival time,while CD90 expression is associated with early HCC recurrence. | Zhe Guo Le-Qun Li Jing-Hang Jiang Chao Ou Li-Xia Zeng Bang-De Xiang | 2014 | World Journal of Gastroenterology2014,20,8: | 18 |
| 4 | In situ preparation of g-C3N4/Bi4O5I2 complex and its elevated photoactivity in Methyl Orange degradation under visible light显示文摘A graphite carbon nitride(g-C3N4)modified Bi4O5I2 composite was successfully prepared insitu via the thermal treatment of a g-C3N4/Bi OI precursor at 400°C for 3 hr.The as-prepared g-C3N4/Bi4O5I2 showed high photocatalytic performance in Methyl Orange(MO)degradation under visible light.The best sample presented a degradation rate of 0.164 min^-1,which is 3.2 and 82 times as high as that of Bi4O5I2 and g-C3N4,respectively.The g-C3N4/Bi4O5I2 was characterized by X-ray powder diffractometer(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),Raman,X-ray photoelectron spectroscopy(XPS),ultraviolet-visible diffuse reflectance spectra(DRS),electrochemical impedance spectroscopy(EIS)and transient photocurrent response in order to explain the enhanced photoactivity.Results indicated that the decoration with a small amount of g-C3N4 influenced the specific surface area only slightly.Nevertheless,the capability for absorbing visible light was improved measurably,which was beneficial to the MO degradation.On top of that,a strong interaction between g-C3N4 and Bi4O5I2 was detected.This interplay promoted the formation of a favorable heterojunction structure and thereby enhanced the charge separation.Thus,the g-C3N4/Bi4O5I2 composite presented greater charge separation efficiency and much better photocatalytic performance than Bi4O5I2.Additionally,g-C3N4/Bi4O5I2 also presented high stability.·O2^- and holes were verified to be the main reactive species. | Zhe Feng Lin Zeng Qingle Zhang Shifeng Ge Xinyue Zhao Hongjun Lin Yiming He | 2020 | Journal of Environmental Sciences2020,32,1: | 12 |
| 5 | Enhanced Mechanical Properties of Multi-layer Graphene Filled Poly(vinyl chloride) Composite Films显示文摘In order to improve mechanical properties of soft poly(vinyl chloride)(PVC) films,we used commercial multi-layer graphene(MLG) with large size and high structural integrity as reinforcing fillers,and prepared MLG/PVC composite films by using conventional melt-mixing methods.Microstructures,static and dynamic mechanical properties of the MLG/PVC composite films were investigated.The results showed that a small amount of MLG loading could greatly increase the mechanical properties of the MLG/PVC composites.The tensile modulus of the 0.96 wt%MLG/PVC composites was up to 40 MPa,increasing by31.3%in comparison to the neat PVC.Such a significant mechanical reinforcement was mainly attributed to uniform dispersion of the large-size MLG,good compatibility and strong interactions among MLG and plasticizers and PVC. | Han Wang Guiyuan Xie Zhe Ying Yu Tong You Zeng | 2015 | Journal of Materials Science & Technology2015,31,4: | 11 |
| 6 | Biodegradation,hemocompatibility and covalent bonding mechanism of electrografting polyethylacrylate coating on Mg alloy for cardiovascular stent显示文摘Organic coatings are the most widely employed approach for the promotion of corrosion resistance of magnesium(Mg)alloys.Unfortunately,traditional organic coatings are weakly bonded to Mg substrates due to physical adsorption.Herein,a polyethylacrylate(PEA)coating was fabricated on Mg-Zn-YNd alloy via electro-grafting.The surface structure and chemical composition were characterized by means of scanning electron microscope(SEM),energy dispersive X-ray spectroscopy(EDS),atomic force microscope(AFM)and Fourier transform infrared(FTIR)as well as time of flight-secondary ion mass spectrometer(To F-SIMS).The results showed that the surface roughness of PEA coating was dominated by scan rate;while the coverage and integrity of PEA coating were mainly affected by the monomer concentration and sweep circles.To F-SIMS results indicated that PEA coating was wholly covered on Mg alloy,and the presence of C2H3Mg-fragment confirmed the covalent bond between PEA coating and Mg alloy.In addition,DFT calculation results of the adsorption of EA molecules with Mg substrate agree well with the experimental phenomena and observation,suggesting that the electrons in 3s orbit of Mg atoms and 2pz orbit of C1 atom participated in the formation of covalent bond between PEA coating and Mg substrate.Potentiodynamic polarization curves and immersion test demonstrated that the PEA coatings could effectively enhance the corrosion resistance of Mg alloy.The platelet adhesion results designated that platelets were barely visible on PEA coating,which implied that PEA coating could effectively prevent the thrombosis and coagulation of platelets.PEA coating might be a promising candidate coating of Mg alloy for cardiovascular stent. | Yong-Xin Yang Zhe Fang Yi-Hao Liu Ya-Chen Hou Li-Guo Wang Yi-Fan Zhou Shi-Jie Zhu Rong-Chang Zeng Yu-Feng Zheng Shao-Kang Guan | 2020 | Journal of Materials Science & Technology2020,42,11: | 9 |
| 7 | In vitro corrosion resistance,antibacterial activity and cytocompatibility of a layer-by-layer assembled DNA coating on magnesium alloy显示文摘A chitosan/deoxyribonucleic acid(CHI/DNA)_(5)coating was constructed by layer-by-layer(LbL)assembly dip coating method with Mg(OH)_(2)coating as an inner protective layer on AZ31 alloy.X-ray diffractometry,X-ray photoelectron spectrometry,Fourier transform infrared spectroscopy and field-emission scanning electron microscopy were utilized to represent the chemical compositions and surface morphologies of the coatings.Electrochemical tests and hydrogen evolution measurements were implemented to confirm the good corrosion resistance of the composite coating in artificial body fluid.Antimicrobial activity of the composite coatings was tested via the plate-counting method,and the cytotoxicity of the samples was appraised by MTT assay and Live/dead staining.A double action was put into effect for the composite coating,which the inner Mg(OH)2 coating plays the part of physical barrier,and the outer(CHI/DNA)5 coating is employed as an inducer to fabricate a biocompatible Ca-P corrosion product coating during immersion,making up for its thin thickness.Otherwise,the composite coating is also beneficial for the growth of bone,resulting from the biomineralization effect of the outer polyelectrolyte multilayer.The good antibacterial property of the(CHI/DNA)5/Mg(OH)2 coating is ascribed to the contact-killing strength of CHI.Thus,the obtained(CHI/DNA)5/Mg(OH)2 coating has a wide application prospect in the field of Mg-based bone implantation. | Lan-Yue Cui Ling Gao Jing-Chao Zhang Zhe Tang Xiao-Li Fan Jia-Cheng Liu Dong-Chu Chen Rong-Chang Zeng Shuo-Qi Li Ke-Qian Zhi | 2021 | Journal of Magnesium and Alloys2021,9,1: | 9 |
| 8 | Devonian Frasnian-Famennian transitional event deposits of Guangxi, South China and their possible tsunami origin显示文摘A suite of event deposits, isochronous and interrelated in origin, occurs widely near the Frasnian- Famennian boundary in Guangxi, South China. It is mainly distributed in the facies areas of the platform-margin slope and inter-platform rift-trough. The rudstone or calcirudite occur in the Liujing section of Hengxian and Luoxiu and Baqi sections of Xiangzhou in the facies area of platform-margin slope. The turbidites are observed in the sections of Yangdi and Baisha of Guilin, Du'an of Debao, Nandong and Sanli of Wuxuan, Xiangtian, Ma'anshan of Xiangzhou, Nayi of Chongzuo, Yunpan of Shanglin in the facies area of inter-platform rift-trough. The massive homogenites occur in sections of Mangchang, Luofu and Road from Nandan to Tian'e and Ma'anshan etc in the facies area of inter-platform rift-trough. Herein event deposits can be correlated in stratohorizon to the turbidite in the bottom of the Lower triangularis Zone in Hony railroad cut of Belgium, Devils Gate of Nevada, USA, Atrous of Morocco, South Urals and Fore-Kolyma of northeastern Siberia of Russia, and erosional discontinuities and brecciation in the Frasnian-Famennian boundary in South Polish-Moravian shelf. The event deposits could be caused by a violent tsunami related to bolide impacts into ocean. | DU YuanSheng GONG YiMing ZENG XiongWei HUANG HongWei YANG JiangHai ZHANG Zhe HUANG ZhiQiang | 2008 | Science China Earth Sciences2008,51,11: | 6 |
| 9 | Cyclooxygenase-2 expression is associated with initiation of hepatocellular carcinoma, while prostaglandin receptor-1 expression predicts survival显示文摘AIM to determine whether cyclooxygenase-2(COX-2) and prostaglandin E1 receptor(EP1) contribute to disease and whether they help predict prognosis.METHODS We retrospectively reviewed the records of 116 patients with hepatocellular carcinoma(HCC) who underwent surgery between 2008 and 2011 at our hospital. Expression of COX-2 and EP1 receptor was examined by immunohistochemistry of formalin-fixed, paraffinembedded tissues using polyclonal antibodies. Possible associations between immunohistochemical scores and survival were determined.RESULTS Factors associated with poor overall survival(OS) were alpha-fetoprotein > 400 ng/m L, tumor size ≥ 5 cm, and high EP1 receptor expression, but not high COX-2 expression. Disease-free survival was not significantly different between patients with low or high levels of COX-2 or EP1. COX-2 immunoreactivity was significantly higher in well-differentiated HCC tissues(Edmondson grade Ⅰ-Ⅱ) than in poorly differentiated tissues(Edmondson grade Ⅲ-Ⅳ)(P = 0.003). EP1 receptor immunoreactivity was significantly higher in poorly differentiated tissue than in well-differentiated tissue(P = 0.001).CONCLUSION COX-2 expression appears to be linked to early HCC events(initiation), while EP1 receptor expression may participate in tumor progression and predict survival. | Hao-Jie Yang Jing-Hang Jiang Yu-ting Yang Xiang-Di Yang Zhe Guo Ya-Peng Qi Feng-Hua Zeng Ke-Lan Zhang Neng-Zhi Chen Bang-De Xiang Le-Qun Li | 2016 | World Journal of Gastroenterology2016,22,39: | 6 |
| 10 | Effect of lentiviral vector-mediated overexpression of hypoxia-inducible factor 1 alpha delivered by pluronic F-127 hydrogel on brachial plexus avulsion in rats显示文摘Brachial plexus avulsion often results in massive motor neuron death and severe functional deficits of target muscles. However, no satisfactory treatment is currently available. Hypoxia-inducible factor 1α is a critical molecule targeting several genes associated with ischemia-hypoxia damage and angiogenesis. In this study, a rat model of brachial plexus avulsion-reimplantation was established, in which C5–7 ventral nerve roots were avulsed and only the C6 root reimplanted. Different implants were immediately injected using a microsyringe into the avulsion-reimplantation site of the C6 root post-brachial plexus avulsion. Rats were randomly divided into five groups: phosphate-buffered saline, negative control of lentivirus, hypoxia-inducible factor 1α(hypoxia-inducible factor 1α overexpression lentivirus), gel(pluronic F-127 hydrogel), and gel + hypoxia-inducible factor 1α(pluronic F-127 hydrogel + hypoxia-inducible factor 1α overexpression lentivirus). The Terzis grooming test was performed to assess recovery of motor function. Scores were higher in the hypoxia-inducible factor 1α and gel +hypoxia-inducible factor 1α groups(in particular the gel + hypoxia-inducible factor 1α group) compared with the phosphate-buffered saline group. Electrophysiology, fluorogold retrograde tracing, and immunofluorescent staining were further performed to investigate neural pathway reconstruction and changes of neurons, motor endplates, and angiogenesis. Compared with the phosphate-buffered saline group, action potential latency of musculocutaneous nerves was markedly shortened in the hypoxia-inducible factor 1α and gel + hypoxia-inducible factor1α groups. Meanwhile, the number of fluorogold-positive cells and ChAT-positive neurons, neovascular area(labeled by CD31 around av ulsed sites in ipsilateral spinal cord segments), and the number of motor endplates in biceps brachii(identified by α-bungarotoxin) were all visibly increased, as well as the morphology of motor endplate in biceps brachil was clear in the hypoxia-inducible factor 1α and gel + hypoxia-inducible factor 1α groups. Taken together, delivery of hypoxia-inducible factor 1α overexpression lentiviral vectors mediated by pluronic F-127 effectively promotes spinal root regeneration and functional recovery post-brachial plexus avulsion. All animal procedures were approved by the Institutional Animal Care and Use Committee of Guangdong Medical University, China. | Tao Wang Li-Ni Zeng Zhe Zhu Yu-Hui Wang Lu Ding Wei-Bin Luo Xiao-Min Zhang Zhi-Wei He Hong-Fu Wu | 2019 | Neural Regeneration Research2019,14,6: | 5 |
| 11 | Shortened snRNA promoters for efficient CRISPR/Cas-based multiplex genome editing in monocot plants显示文摘Dear Editor,CRISPR(clustered regularly interspaced short palindromic repeats)/Cas genome editing is a powerful tool for introducing specific mutations in organisms including plants.The system is composed of a nuclease such as Cas9 or Cas12a and an engineered single-guide RNA(sgRNA)incorporating a target sequence(Li et al.,2019).A Cas9/sgRNA complex recognizes its target site in the genome,resulting in a mutation at that site. | Yu Hao Wubei Zong Dongchang Zeng Jingluan Han Shuifu Chen Jianian Tang Zhe Zhao Xiaojuan Li Kun Ma Xianrong Xie Qinlong Zhu Yuanling Chen Xiucai Zhao Jingxin Guo Yao-Guang Liu | 2020 | Science China(Life Sciences)2020,63,6: | 4 |
| 12 | Basal-plane stacking-fault energies of Mg alloys: A first-principles study of metallic alloying effects显示文摘Generalized stacking-fault energies(GSFEs) of basal-plane stacking faults I1 and I2 in Mg alloys have been studied based on first-principles calculations, where 43 alloying elements were considered. It is found that the most contributing features of alloying elements to GSFEs are bulk modulus, equilibrium volume,binding energy, atomic radius and ionization energy. Both bulk modulus and ionization energy exhibit positive relationships with GSFEs, and the others show opposite relationships. Multiple regressions have been performed to offer a quantitative prediction for basal-plane GSFEs in Mg-X systems. GSFEs, alloying effects of elements and the prediction model established within this work may provide guidelines for new Mg alloys design with better ductility. | Qing Dong Zhe Luo Hong Zhu Leyun Wang Tao Ying Zhaohui Jin Dejiang Li Wenjiang Ding Xiaoqin Zeng | 2018 | Journal of Materials Science & Technology2018,34,10: | 4 |

| 14 | Improved esophageal squamous cell carcinoma screening effectiveness by risk-stratified endoscopic screening:evidence from high-risk areas in China显示文摘Background:Risk-stratified endoscopic screening(RSES),which offers endoscopy to those with a high risk of esophageal cancer,has the potential to increase effectiveness and reduce endoscopic demands compared with the universal screening strategy(i.e.,endoscopic screening for all targets without risk prediction).Evidence of RSES in high-risk areas of China is limited.This study aimed to estimate whether RSES based on a 22-score esophageal squamous cell carcinoma(ESCC)risk prediction model could optimize the universal endoscopic screening strategy for ESCC screening in high-risk areas of China.Methods:Eight epidemiological variables in the ESCC risk prediction model were collected retrospectively from 26,618 individuals aged 40-69 from three high-risk areas of China who underwent endoscopic screening betweenMay 2015 and July 2017.The model’s performance was estimated using the area under the curve(AUC).Participants were categorized into a high-risk group and a low-risk group with a cutoff score having sensitivities of both ESCC and severe dysplasia and above(SDA)at more than 90.0%.Results:The ESCC risk prediction model had an AUC of 0.80(95% confidence interval:0.75-0.84)in this external population.We found that a score of 8(ranging from 0 to 22)had a sensitivity of 94.2% for ESCC and 92.5% for SDA.The RSES strategy using this threshold score would allow 50.6% of endoscopies to be avoided and save approximately US$0.59 million compared to universal endoscopic screening among 26,618 participants.In addition,a higher prevalence of SDA(1.7%vs.0.9%),a lower number need to screen(60 vs.111),and a lower average cost per detected SDA(US$3.22 thousand vs.US$5.45 thousand)could have been obtained by the RSES strategy.Conclusions:The RSES strategy based on individual risk has the potential to optimize the universal endoscopic screening strategy in ESCC high-risk areas of China. | He Li Chao Ding Hongmei Zeng Rongshou Zheng Maomao Cao Jiansong Ren Jufang Shi Dianqin Sun Siyi He Zhixun Yang Yiwen Yu Zhe Zhang Xibin Sun Guizhou Guo Guohui Song Wenqiang Wei Wanqing Chen Jie He | 2021 | Cancer Communications2021,41,8: | 3 |
| 15 | A fast,edge-preserving,distance-regularized model with bilateral filtering for oil spill segmentation of SAR images显示文摘Marine oil spills are among the most significant sources of marine pollution.Synthetic aperture radar(SAR)has been used to improve oil spill observations because of its advantages in oil spill detection and identification.However,speckle noise,weak boundaries,and intensity inhomogeneity often exist in the oil spill regions of SAR imagery,which will seriously aff ect the accurate identification of oil spills.To enhance marine oil spill segmentation of SAR images,a fast,edge-preserving framework based on the distance-regularized level set evolution(DRLSE)model was proposed.Specifically,a bilateral filter penalty term is designed and incorporated into the DRLSE energy function(BF-DRLSE)to preserve the edges of oil spills,and an adaptive initial box boundary was selected for the DRLSE model to reduce the operation time complexity.Two sets of RadarSat-2 SAR data were used to test the proposed method.The experimental results indicate that the bilateral filtering scheme incorporated into the energy function during level set evolution improved the stability of level set evolution.Compared with other methods,the proposed improved BF-DRLSE algorithm displayed a higher overall segmentation accuracy(97.83%).In addition,using an appropriate initial box boundary for the DRLSE method accelerated the global search process,improved the accuracy of oil spill segmentation,and reduced computational time.Therefore,the results suggest that the proposed framework is eff ective and applicable for marine oil spill segmentation. | Wandi WANG Hui SHENG Yanlong CHEN Shanwei LIU Jijun MAO Zhe ZENG Jianhua WAN | 2021 | Journal of Oceanology and Limnology2021,39,4: | 3 |
| 16 | Coexistence of multiple genotypes of porcine epidemic diarrhea virus with novel mutant S genes in the Hubei Province of Chinain 2016显示文摘The emergence of highly virulent porcine epidemic diarrhea virus(PEDV) variants in China caused huge economic losses in 2010. Since then, large-scale sporadic outbreaks of PED caused by PEDV variants have occasionally occurred in China. However, the molecular diversity and epidemiology of PEDV in different provinces has not been completely understood. To determine the molecular diversity of PEDV in the Hubei Province of China, we collected 172 PED samples from 34 farms across the province in 2016 and performed reverse transcription polymerase chain reaction(RTPCR)by targeting the nucleocapsid(N) gene. Seventy-four samples were found to be PEDVpositive.We further characterized the complete spike(S) glycoprotein genes from the positive samples and found 21 different S genes with amino acid mutations. The PEDV isolates here presented most of the genotypes which were found previously in field isolates in East and SouthEast Asia, North America, and Europe. Besides the typical Genotypes Ⅰ and Ⅱ, the INDEX groups were also found. Importantly, 58 new amino acids mutant sites in the S genes, including 44 sites in S1 and 14 sites in S2, were first described. Our results revealed that the S genes of PEDV showed variation and that diverse genotypes of PEDV coexisted and were responsible for the PED outbreaks in Hubei in 2016. This work highlighted the complexity of the epidemiology of PEDV and emphasized the need for reassessing the efficacy of classic PEDV vaccines against emerging variant strains and developing new vaccines to facilitate the prevention and control of PEDV in fields. | Zhe Zeng Ting-Ting Li Xin Jin Fu-Hu Peng Nian-Hua Song Gui-Qing Peng Xing-Yi Ge | 2017 | Virologica Sinica2017,32,4: | 3 |
| 17 | Highly soluble organic nitrate additives for practical lithium metal batteries显示文摘The stability of lithium metal anodes essentially dictates the lifespan of high-energy-density lithium metal batteries.Lithium nitrate(LiNO_(3))is widely recognized as an effective additive to stabilize lithium metal anodes by forming LiN_(x)O_(y)-containing solid electrolyte interphase(SEI).However,its poor solubility in electrolytes,especially ester electrolytes,hinders its applications in lithium metal batteries.Herein,an organic nitrate,isosorbide nitrate(ISDN),is proposed to replace LiNO_(3).ISDNhas a high solubility of 3.3M in ester electrolytes due to the introduction of organic segments in the molecule.The decomposition of ISDN generates LiN_(x)O_(y)-rich SEI,enabling uniform lithium deposition.The lifespan of lithium metal batteries with ISDN significantly increases from 80 to 155 cycles under demanding conditions.Furthermore,a lithium metal pouch cell of 439Whkg^(−1) delivers 50 cycles.This work opens a new avenue to develop additives by molecular modifications for practical lithium metal batteries. | Zhe Wang Li-Peng Hou Zheng Li Jia-Lin Liang Ming-Yue Zhou Chen-Zi Zhao Xiaoyuan Zeng Bo-Quan Li Aibing Chen Xue-Qiang Zhang Peng Dong Yingjie Zhang Jia-Qi Huang Qiang Zhang | 2023 | Carbon Energy2023,5,1: | 2 |
| 18 | A graphene-laminated electrode with high glucose oxidase loading for highly-sensitive glucose detection显示文摘Graphene oxide(GO) has received considerable attention for glucose detection because of high surface area, abundant functional groups, and good biocompatibility. Defects and functional groups of the GO are beneficial to immobilization of glucose oxidase(GOD), but sacrificing electron-transfer capability for highly-sensitive detection. In order to obtain high GOD loading and highly-sensitive detection of biosensors, we first designed and fabricated a graphene-laminated electrode by combining GO and edgefunctionalized graphene(FG) layers together onto glassy-carbon electrode. The graphene-laminated electrodes exhibited faster electron transfer rate, higher GOD loading of 3.80 × 10^(-9) mol·cm^(-2), and higher detection sensitivity of 46.71 μA·mM^(-1)·cm^(-2) than other graphene-based biosensors reported in literature. Such high performance is mainly attributed to the abundant functional groups of GO, high electrical conductivity of FG, and strong interactions between components in the graphene-laminated electrodes.By virtue of their high enzyme loading and highly-sensitive detection, the graphene-laminated electrodes show great potential to be widely used as high-performance biosensors in the field of medical diagnosis. | Yabin Hao Minghe Fang Chuan Xu Zhe Ying Han Wang Rui Zhang Hui-Ming Cheng You Zeng | 2021 | Journal of Materials Science & Technology2021,,7: | 2 |
