| 1 | Factors Associated with Thrombolysis Outcome in Ischemic Stroke Patients with Atrial Fibrillation显示文摘The outcome of early intravenous thrombolysis for ischemic stroke in patients with atrial fibrillation(AF)is worse than that without thrombosis. How to increase the efficacy of intravenous thrombolysis for AF-related ischemic stroke remains largely unknown. In this study, we investigated factors that influence the effect of intravenous thrombolysis in these patients. Our results showed that thrombolysis was independently associated with a favorable outcome(P \ 0.001) and did not influence the mortality of AF-related ischemic stroke, although it increased the risk of hemorrhage within 24 h after treatment. Risk factors for a poor outcome at admission were:heart failure(P = 0.045); high systolic pressure(P = 0.039); high blood glucose(P = 0.030); and a high National Institutes of Health Stroke Scale(NIHSS) score(P \ 0.001). Moreover, high systolic pressure at admission(P = 0.007), high blood glucose(P = 0.027), and a high NIHSS score(P \ 0.001) were independent risk factors for mortality at 3 months. Besides thrombolysis, a high NIHSS score(P = 0.006) and warfarin taken within 48 h before stroke onset(P = 0.032) were also independent risk factors for symptomatic hemorrhage within 24 h after treatment. Ischemic stroke patients with AF benefited from intravenous thrombolysis with recombinant tissue plasminogen activator within 4.5 h after stroke. | Qiuyun Zhao Xiaobo Li Wanli Dong Min Ye Yongjun Cao Meijuan Zhang Qiantao Cheng Junshan Zhou Guofang Chen Ming Yu Shanshan Hong Xiue Wei Bei Wang Guiyun Cui Peng Zhang Hong Ding Rongzhen Xu Yan Chen Yun Xu | 2016 | Neuroscience Bulletin2016，32，2： | 13 |
| 2 | Arbitrary focusing lens by holographic metasurface显示文摘In this paper, an ultrathin metalens has been proposed based on a holographic metasurface that consists of elongated apertures in 40 nm gold film, which exhibit intriguing properties such as on-and off-axis focusing and also can concentrate light into multiple, discrete spots for circularly polarized incident lights. First, the spatial transmission phase distributions of the designed metalens with arbitrary focusing can be obtained by computergenerated holography. Then, the discrete phase distributions can be continuously encoded by subwavelength nanoapertures with spatially varying orientations in gold film. The simulation results show that our designed metalens can work efficiently for different types of focusing. Finally, our metasurface shows superior broadband characteristics between 670 and 810 nm, and the corresponding focal lengths of the designed lenses also can be efficiently modulated with the incident lights at different wavelengths. | Rongzhen Li Zhongyi Guo Wei Wang Jingran Zhang Keya Zhou Jianlong Liu Shiliang Qu Shutian Liu Jun Gao | 2015 | Photonics Research2015，3，5： | 6 |
| 3 | Ultra-thin,planar,broadband,dual-polarity plasmonic metalens显示文摘An ultrathin,planar,broadband metalens composed of metal rectangular split-ring resonators(MRSRRs) has been designed,which shows dual-polarity characteristics for different types of circularly polarized(CP) light incidence.The designed metalens can be considered as the focusing lens and the diverging lens under left-handed CP and right-handed CP light incidence,respectively.The phase discontinuity of the cross-polarized transmission light is produced by optical-axis rotation through modulating two arms’ lengths of the MRSRR.The MRSRR metalens possesses a wavelength-controllable focal length and a relatively larger chromatic aberration compared with the conventional lenses.And the focal length changes from 9 to 7 μm with incident wavelength from 740 to 950 nm.The dual-polarity flat metalens opens a door for new applications of phase discontinuity devices,and it will promote the fabricating capability of on-chip or fiber-embedded optical devices. | Wei Wang Zhongyi Guo Rongzhen Li Jingran Zhang Yi Liu Xinshun Wang and Shiliang Qu | 2015 | Photonics Research2015，3，3： | 4 |
| 4 | Kinetics, thermodynamics, and equilibrium of As(Ⅲ),Cd(Ⅱ), Cu(Ⅱ) and Pb(Ⅱ) adsorption using porous chitosan bead-supported MnFe_(2)O_(4) nanoparticles显示文摘A novel porous nanocomposite,cross-linked chitosan and polyethylene glycol(PEG) bead-supported MnFe_(2) O_(4) nanoparticles(CPM),was developed as an efficient adsorbent to remove metalloid(As(Ⅲ))and heavy metals(Cd(Ⅱ),Cu(Ⅱ),and Pb(Ⅱ)).The characteristics of CPM showed a porous structure,well dispersed MnFe_(2) O_(4),and several of hydroxyl and amino groups(-OH,-NH_(2)).Batch experiments demonstrated that the best adsorption property of As(Ⅲ),Cd(Ⅱ),Cu(Ⅱ),and Pb(Ⅱ) was achieved within 8 h with maximum adsorption capacities of 9.90,9.73,43.94,and 11.98 mg/g,respectively.Competitive and synergistic effects(particularly precipitation) were included in the co-adsorption mechanism of As(Ⅲ) and heavy metals.Thereinto,As(Ⅲ) was partly oxidized by MnFe_(2) O_(4) to As(V),and both were coordinated on MnFe_(2) O_(4) nanoparticles.Pb(Ⅱ) could also bind to MnFe_(2) O_(4) by ion exchange and electrostatic attraction.Furthermore,Cd(Ⅱ) and Cu(Ⅱ) tended to be coordinated on chitosan.Therefore,CPM can serve as a remediation material for water and soil co-contaminated with As(Ⅲ) and heavy metals. | Hongxia Li Hongbing Ji Xinglan Cui Xiaokui Che Qidong Zhang Juan Zhong Rongzhen Jin Lei Wang Yi Luo | 2021 | International Journal of Mining Science and Technology2021，31，6： | 2 |

| 10 | Influence of substituting B_(2)O_(3) with Li_(2)O on the viscosity,structure and crystalline phase of low-reactivity mold flux显示文摘The low-reactivity mold flux with low SiO_(2)content is considered suitable for the continuous casting of high-aluminum steel since it can significantly reduce the reaction between Al in steel and SiO_(2)in mold flux.However,the traditional low-reactivity mold flux still presents some problems such as high viscosity and strong crystallization tendency.In this study,the co-addition of Li_(2)O and B_(2)O_(3)in CaO–Al_(2)O_(3)–10wt%Si O_(2)based low-reactivity mold flux was proposed to improve properties of mold flux for high-aluminum steel,and the effect of Li_(2)O replacing B_(2)O_(3)on properties of mold flux was investigated.The viscosity of the mold flux with 2wt%Li_(2)O and 6wt%B_(2)O_(3)reached a minimum value of 0.07 Pa·s.The break temperature and melting point showed a similar trend with the viscosity.Besides,the melt structure and precipitation of the crystalline phase were studied using Raman and X-ray diffraction spectra to better understand the evolution of viscosity.It demonstrated that with increasing Li_(2)O content in the mold flux from 0 to 6 wt%,the degree of polymerization of aluminate and the aluminosilicate network structure increased because of increasing Li+released by Li_(2)O,indicating the added Li_(2)O was preferentially associated with Al^(3+)as a charge compensator.The precipitation of LiAlO_(2)crystalline phase gradually increased with the replacement of B_(2)O_(3)by Li_(2)O.Therefore,Li_(2)O content should be controlled below 2wt%to avoid LiAlO_(2)precipitation,which was harmful to the continuous casting of highaluminum steels. | Rongzhen Mo Xubin Zhang Ying Ren Junjie Hu Lifeng Zhang | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，7： | 0 |

| 12 | Chromate separation by selective crystallization显示文摘A new paradigm to remove toxic chromate anions from aqueous solution by crystallization of chromatewater clusters with imine-linked guanidinium cationic ligands is introduced.The guanidium-based cationic ligand was easily prepared through the imine condensation of an alde hyde and aminoguanidine hydrochloride.The cationic imine-linked guanidinium liga nd(BBIG-CI)showed a high re moval capacity(292.5 mg/g)in the solutions.Rapid decontamination of chromate anions from the wastewater by this cationic ligand was resulted from an instantaneous crystallization.The produced guanidium chromate salts have an extremely low solubility(Ksp,BBIG=8.19×10^9).Such superior removal performance of these mate rials was attributed to the cha rge-assisted hydrogen bonding between the cationic ligand and chromate-water hydrate anions,which was revealed by the single-crystal X-ray diffraction analysis and density functional theory(DFT)calculations.In addition,the succes s ful recove ry of the guanidium-based ligand makes it more attractive for real-world applications. | Xijian Chen Xing Dai Rongzhen Xie Jie Li Afshin Khayambashi Lei Xu Chuang Yang Nannan Shen Yaxing Wang Linwei He Yugang Zhang Chengliang Xiao Zhifang Chai Shuao Wanga | 2020 | Chinese Chemical Letters2020，31，7： | 0 |
| 13 | Rational design of a cationic polymer network towards record high uptake of ^(99)TcO_(4)^(-)in nuclear waste显示文摘^(99)Tc is a long-lived radionuclide present in large amounts as TcO_(4)^(-)-anion in used nuclear fuel.Its removal from the waste stream is highly desirable because of its interference capability with actinide separation and its volatile nature during the nuclear waste vitrification process.Despite the progress achieved in the past few years,the design of anion-exchange materials with optimized Tc uptake property and improved stability under the extreme condition is still a research goal beneficial for reducing the volume of secondary radioactive solid waste generated during the waste partitioning process.However,their design philosophy remains elusive,with challenges coming from charge repulsion,steric hindrance,and insufficient reactive sites within the materials.Herein,we present a design philosophy of cationic polymer network materials for TcO_(4)^(-)separation by systematic precursor screening and structure prediction.This affords an optimized material,SCU-CPN-2(SCU=Soochow University),with extremely high positive charge density while maintaining high radiation resistance.SCU-CPN-2 exhibits a record high adsorption capacity1,467 mg/g towards the surrogate ReO_(4)^(-)compared to all anion-exchange materials reported up to date.In addition to ultrafast adsorption kinetics,SCU-CPN-2 has remarkable selectivity over nitrate and sulfate,and facile recyclability. | Jie Li Long Chen Nannan Shen Rongzhen Xie Matthew VSheridan Xijian Chen Daopeng Sheng Duo Zhang Zhifang Chai Shuao Wang | 2021 | Science China Chemistry2021，64，7： | 0 |
| 14 | Low expression of centrosomal protein 78(CEP78)is associated with poor prognosis of colorectal cancer patients显示文摘Background: Centrosomal protein 78(CEP78) has been characterized as a component of the centrosome required for the regulation of centrosome-related events during the cell cycle, but its role in human cancers remains unclear. This study aimed to investigate the role and the clinical value of CEP78 in colorectal cancer(CRC).Methods: Quantitative real-time polymerase chain reaction(q RT-PCR) and immunohistochemistry were performed to examine CEP78 expression in CRC tissues and adjacent noncancerous tissues. The association between CEP78 expression and clinical outcomes of CRC patients was determined. The effect of CEP78 on cell growth was examined in vitro by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide(MTT) assay, colony formation, and flow cytometry assays and in vivo using a nude mouse model.Results: The expression level of CEP78 was significantly lower in tumor tissues than in the adjacent normal tissues(P < 0.01). Low CEP78 expression was significantly associated with poor differentiation(P etastasis(P = 0.003), large tumor size(P = 0.017), lymphatic mtient= 0.034), distant metastasis(P s with low CEP78 expression h= 0.029), and advanced stage(P Meier analysis indicated that paad shorter survival than those wit= 0.011). Kaplan–h high CEP78 expression(P < 0.01). Overexpression of CEP78 in CRC cells significantly reduced cell viability and colony formation in vitro and halted tumor growth in vivo. Further study showed that CEP78 reintroduction in CRC cells resulted in G2/M phase arrest rather than cell apoptosis.Conclusions: CEP78 might function as a tumor suppressor and serve as a novel prognostic marker in CRC. | Meifang Zhang Tingmei Duan Li Wang Jianjun Tang Rongzhen Luo Ruhua Zhang Tiebang Kang | 2016 | Chinese Journal of Cancer2016，35，10： | 0 |

| 16 | 啮齿类动物出血性休克模型中血浆对内皮细胞多糖包被的恢复作用显示文摘背景在出血性休克的创伤患者应用血浆为主的复苏与死亡率下降有关。尽管有学者提出通过替代凝血蛋白可产生有益的效果,但是输入血浆的保护作用可能机制尚不明了。我们以前在细胞培养模型中的研究显示,与晶体液相比,血浆可降低内皮细胞的通透性。多糖包被由粘附于多配体聚糖骨架上的蛋白多糖和糖蛋白组成,共同保护下层的内皮细胞。我们假设,血浆对内皮细胞的保护作用,部分是由于出血性休克后内皮细胞多糖包被的恢复和多配体聚糖-1的维持所致。方法在大鼠建立出血性休克模型使其平均动脉压在30mmHg维持90分钟,然后以乳酸林格(1actatedRinger's,LR)液或新鲜血浆复苏,使其平均动脉压达到80mmHg,相当于假手术组或单纯休克组动物。2小时后,提取肺组织多配体聚糖的mRNA,使用抗多配体聚糖-l免疫染色或使用苏木精伊红染色。为了特异地检测出血浆对内皮细胞的影响,我们通过小肠系膜灌注镧溶液,然后应用电子显微镜鉴别出小静脉,观察其多糖包被。所有数据以均数±标准差来表示。运用单尾方差分析合并Tukey事后检验来分析结果。结果电子显微镜显示出血性休克后多糖包被发生降解,输注血浆可部分恢复多糖包被水平而LR无该效应。血浆复苏组动物肺组织多配体聚糖.1的mRNA表达(2.76±0.03)明显高于单纯休克组(1.39±0.22)或ut组(0.82±0.03),并且与细胞表面多配体聚糖.1的免疫染色相关。休克也可导致组织病理学评分方面肺损伤显著(1.63±0.26),应用血浆复苏可减轻该损伤(0.67±0.17),而LR无该效应(2.0±0.25)。结论血浆的保护作用可能部分是由于出血性休克后血浆能恢复内皮细胞多糖包被水平,并维持多配体聚糖-1水平。 | RosemaryA.
