| 1 | Inconsistent seasonal variation of antibiotics between surface water and groundwater in the Jianghan Plain:Risks and linkage to land uses显示文摘Antibiotics are widely used in humans and animals,but their transformation from surface water to groundwater and the impact of land uses on them remain unclear.In this study,14 antibioticswere systematically surveyed in a complex agricultural area in Central China.Results indicated that the selected antibiotic concentrations in surface waters were higher in winter(average:32.7 ng/L)than in summer(average:17.9 ng/L),while the seasonal variation in groundwaters showed an opposite trend(2.2 ng/L in dry winter vs.8.0 ng/L in summer).Macrolides were the predominant antibiotics in this area,with a detected frequency of over 90%.A significant correlation between surface water and groundwater antibiotics was only observed in winter(R^(2)=0.58).This study further confirmed the impact of land uses on these contaminants,with optimal buffer radii of 2500 m in winter and 500 m in summer.Risk assessment indicated that clarithromycin posed high risks in this area.Overall,this study identified the spatiotemporal variability of antibiotics in a typical agricultural area in Central China and revealed the impact of land uses on antibiotic pollution in aquatic environments. | Xi Liu Zhi Wang Lu Zhang Weiying Fan Chao Yang Enhua Li Yun Du Xuelei Wang | 2021 | Journal of Environmental Sciences2021,33,11: | 9 |

| 3 | The expression of vascular endothelial growth factor(VEGF)/endostatin(ES)and VEGF receptor 2(VEGFR2)/ES is associated with NSCLC prognosis显示文摘Objective The aim of our study was to detect the expression of angiogenesis inhibitory proteins and angiogenesis promotive proteins in the postoperative tumor tissue of non-small cell lung cancer(NSCLC)patients.We also investigated the relationship of protein expression with clinical characteristics and prognosis.Methods We examined the expression of vascular endothelial growth factor(VEGF),VEGF receptor 2(VEGFR2),and endostatin(ES)proteins in 255 specimens resected from NSCLC patients,using immune histochemistry(IHC).We then evaluated the relationships between the expression of the three proteins and clinical characteristics such as stage,histological type,differentiation,gender,tobacco use,and age.According to the value of VEGF/ES,we divided the cohort into angiogenesis-promoting group A,angiogenesis-inhibiting group A,and balance group A.The survival differences in the three groups were evaluated to determine the prognostic value of VEGF/ES.Similarly,we tested the prognostic value of VEGFR2/ES.Results VEGF-positive expression was observed in 93 patients(36.4%).VEGF expression was not correlated with the clinical characteristics.VEGFR2-positive expression was observed in 103 patients(40.4%).The expression of VEGFR2 was correlated with the clinical stage(χ^(2)=21.414,P=0.045)and histological type(χ^(2)=26.911,P=0.008).ES-positive expression was observed in 140 patients(54.9%).The expression of ES was correlated with the clinical stage(χ^(2)=26.504,P=0.009).When evaluating the prognostic values of VEGF/ES and VEGFR2/ES,the prognosis of the angiogenesis balance group was similar to that of the angiogenesis-inhibiting group.The minimum survival time was observed in the angiogenesis-promoting group.Conclusion VEGF/ES and VEGFR2/ES in resected tumors have prognostic value in postoperative NSCLC patients.The survival time of the population with predominant angiogenic factors was short. | Yuan Yang Baohua Lu Baolan Li Weiying Li Mei Jiang Wentao Yue Qunhui Wang Tongmei Zhang | 2021 | Oncology and Translational Medicine2021,7,4: | 1 |

| 5 | Phase diagram of the CsBr-CaBr_2 system显示文摘The phase diagram of the CsBr-CaBr2 system was re-determined by using differential thermal analysis and high temperature and room temperature X-ray diffraction analysis. It is concluded that there are three intermediate compounds in this system: a congruently melting compound, CsCaBr3, with a melting point of 823°C and two incongruently melting compounds, Cs2CaBr4 and Cs3Ca2Br7, whose peritectic points being 597°C and 635°C, respectively. X-ray diffraction analysis indicated that compound CsCaBr3 is of slightly distorted perovskite structure. | BAO Xinhua CHEN Nianyi LU Wencong CHENG Zhixuan LUO Yunyun LU Weiying XIA Yiben | 2006 | Rare Metals2006,25,3: | 1 |
| 6 | Gelatin-Based Metamaterial Hydrogel Films with High Conformality for Ultra-Soft Tissue Monitoring显示文摘Implantable hydrogel-based bioelectronics(IHB)can precisely monitor human health and diagnose diseases.However,achieving biodegradability,biocompatibility,and high conformality with soft tissues poses significant challenges for IHB.Gelatin is the most suitable candidate for IHB since it is a collagen hydrolysate and a substantial part of the extracellular matrix found naturally in most tissues.This study used 3D printing ultrafine fiber networks with metamaterial design to embed into ultra-low elastic modulus hydrogel to create a novel gelatin-based conductive film(GCF)with mechanical programmability.The regulation of GCF nearly covers soft tissue mechanics,an elastic modulus from 20 to 420 kPa,and a Poisson’s ratio from-0.25 to 0.52.The negative Poisson’s ratio promotes conformality with soft tissues to improve the efficiency of biological interfaces.The GCF can monitor heartbeat signals and respiratory rate by determining cardiac deformation due to its high conformability.Notably,the gelatin characteristics of the biodegradable GCF enable the sensor to monitor and support tissue restoration.The GCF metamaterial design offers a unique idea for bioelectronics to develop implantable sensors that integrate monitoring and tissue repair and a customized method for endowing implanted sensors to be highly conformal with soft tissues. | Yuewei Chen Yanyan Zhou Zihe Hu Weiying Lu Zhuang Li Ning Gao Nian Liu Yuanrong Li Jing He Qing Gao Zhijian Xie Jiachun Li Yong He | 2024 | Nano-Micro Letters2024,16,2: | 0 |
| 7 | QTL Mapping for Plant Height of Wheat under Different Irrigation Modes显示文摘In order to mine gene loci associated with drought resistance and water use efficiency,and provide guidance for the breeding of drought-resistant wheat varieties,quantitative trait loci(QTLs)for plant height(PH)and stem height(SH)of wheat were evaluated using a population of 302 recombinant inbred lines(RILs)derived from a cross between drought-tolerant cultivar Luohan 2 and water-sensitive cultivar Weimai 8 under different water regimes in six environments.Totally 17 additive QTLs for PH and SH were identified and distributed on chromosomes 2B,3A,3B,4A,5A,5D,6B,7A and 7B,respectively,which explained3.3%to 26.95%phenotypic variations,with additive effect of 1.919 6 to 5.382 8 cm.Among them,14 QTLs,24 times and 5 QTLs,7 times were detected in three irrigation environments and three drought stress environments,respectively.Both the number of QTLs for PH and the times detected in drought stress environments were significantly less than those in irrigation environments.Of all the 17 QTLs for PH,12 were detected only in irrigation environment,three QTLs were detected only in drought stress environment,and two QTLs were detected in both environments,suggesting that the expression of the genes is greatly influenced by environmental condition.QPh-WL-7A.3 detected between maker Xbarc049 and Xgwm273 on chromosome 7A in all the three drought stress environments,can enhance2.481 5-3.697 2 cm of PH,explain 8.6%-10.0%additive effect,so it is useful for the genetic improvement of drought tolerance and molecular marker-assisted selection in wheat. | Yanyun REN Ling HUANG Minmin SHAO Leiming SUN Kai ZHAO Jinping WANG Xingke XU Weiying FENG Jifeng WANG Lu YAN Shichong WANG Lin WANG | 2017 | Agricultural Biotechnology2017,6,4: | 0 |

| 9 | Deformation Behavior and Microstructure Evolution of AZ31 Mg Alloy by Forging-Bending Repeated Deformation with Multi-pass Lowered Temperature显示文摘In this study, AZ31 Mg alloy was processed by a new severe plasticity deformation methodology with multi-pass lowered temperature, and the deformation behavior and microstructure evolution were investigated by finite element method and electron back-scattered diffraction technique and hardness. The results show that with the increase of deformation pass, the strain gradually springs, and its interval distribution tends to homogenize. Meanwhile, the effective strain increases dramatically with the shear force sudden upgrade in the deformation process. Moreover, the new deformation technique can refine grain size remarkably. With the passes on, {10-12} tensile twins behavior and the pyramidal < c + a > slip are triggered more frequently, leading to the completeness of dynamic recrystallization (DRX) gradually, which weaken and disperse the basal texture obviously. Besides, the standard deviation of hardness is getting smaller, and the maximum can reach 78.40 HV on average, which can be attributed to the even large strain distribution, complete DRX, and the high geometrically necessary dislocation. | Minhao Li Liwei Lu Yuhui Wei Min Ma Weiying Huang | 2023 | Acta Metallurgica Sinica(English Letters)2023,36,8: | 0 |
| 10 | HBXIP blocks myosin-ⅡA assembly by phosphorylating and interacting with NMHC-ⅡA in breast cancer metastasis显示文摘Tumor metastasis depends on the dynamic balance of the actomyosin cytoskeleton.As a key component of actomyosin filaments,non-muscle myosin-ⅡA disassembly contributes to tumor cell spreading and migration.However,its regulatory mechanism in tumor migration and invasion is poorly understood.Here,we found that oncoprotein hepatitis B X-interacting protein(HBXIP) blocked the myosin-ⅡA assemble state promoting breast cancer cell migration.Mechanistically,mass spectrometry analysis,co-immunoprecipitation assay and GST-pull down assay proved that HBXIP directly interacted with the assembly-competent domain(ACD) of non-muscle heavy chain myosin-ⅡA(NMHC-ⅡA).The interaction was enhanced by NMHC-ⅡA S1916 phosphorylation via HBXIP-recruited protein kinase PKCβⅡ.Moreover,HBXIP induced the transcription of PRKCB,encoding PKCβⅡ,by coactivating Sp1,and triggered PKCβⅡ kinase activity.Interestingly,RNA sequencing and mouse metastasis model indicated that the anti-hyperlipidemic drug bezafibrate(BZF) suppressed breast cancer metastasis via inhibiting PKCβⅡ-mediated NMHC-ⅡA phosphorylation in vitro and in vivo.We reveal a novel mechanism by which HBXIP promotes myosin-ⅡA disassembly via interacting and phosphorylating NMHC-ⅡA,and BZF can serve as an effective anti-metastatic drug in breast cancer. | Lu Zhang Xiaolei Zhou Bowen Liu Xuhe Shi Xianmeng Li Feifei Xu Xueli Fu Xue Wang Kai Ye Tianzhi Jin Huimin Sun Qianqian Li Weiying Zhang Lihong Ye | 2023 | Acta Pharmaceutica Sinica B2023,13,3: | 0 |
| 11 | Influence of Ca Content on Microstructure and Mechanical Properties of Extruded Mg–Al–Ca–Mn Alloys显示文摘Herein,the effects of Ca content on microstructure,texture and mechanical properties of extruded Mg–3Al–0.4Mn–xCa(x=0.4,0.8 and 1.2 wt%)rods are systematically investigated.The results reveal that the alloy,with Ca content of 0.8 wt%,exhibits the highest strength and ductility,possessing an ultimate tensile strength of 267.57 MPa and elongation(EL)of 16%.This is mainly due to the gradual transformation of typical fiber texture into a texture with a[10-11]component parallel to the extrusion direction(ED),which increases the Schmid factor of pyramidal slip and enhances the activation rate of pyramidal(c+a)slip.Simultaneously,the as-formed spherical phases and segregation of Ca at grain boundaries render a significant influence on the strength and ductility of the alloy. | Weiying Huang Jianhua Chen Zhen Jiang Xi Xiong Wei Qiu Jian Chen Xianwei Ren Liwei Lu | 2023 | Acta Metallurgica Sinica(English Letters)2023,36,3: | 0 |
| 12 | Novel structural designs of 3D-printed osteogenic graft for rapid angiogenesis显示文摘Large bone defect regeneration has always been recognized as a challenging clinical problem due to the difficulty of revascularization.Conventional treatments exhibit certain inherent disadvantages(e.g.,secondary injury,immunization,and potential infections).However,three-dimensional(3D)printing technology as an emerging field can serve as an effective approach to achieve satisfactory revascularization while making up for the above limitations.A wide variety of methods can be used to facilitate blood supply during the design of a 3D-printed scaffold.Importantly,the scaffold structure lays a foundation for the entire printing object;any method to promote angiogenesis can be effective only if it is based on well-designed scaffolds.In this review,different designs related to angiogenesis are summarized by collecting the literature from recent years.The 3D-printed scaffolds are classified into four major categories and discussed in detail,from elementary porous scaffolds to the most advanced bone-like scaffolds.Finally,structural design suggestions to achieve rapid angiogenesis are proposed by analyzing the above architectures.This review can provide a reference for organizations or individual academics to achieve improved bone defect repair and regeneration using 3D printing. | Weiying Lu Yang Shi Zhijian Xie | 2023 | Bio-Design and Manufacturing2023,6,1: | 0 |
