| 1 | Radiative forcing and global warming potential of perfluorocarbons and sulfur hexafluoride显示文摘We developed two radiation parameterizations with different resolutions(17-band and 998-band) for perfluorocarbons(PFCs) and sulfur hexafluoride(SF6) using the updated High-resolution Transmission Molecular Absorption(HITRAN) 2004 database and the correlated k-distribution method.We analyzed the impacts of the two radiation schemes on heating rates.Then we studied their instantaneous radiative efficiency,stratospheric adjusted radiative efficiency,global warming potential(GWP),and global temperature potential(GTP),for both clear-and all-sky conditions using a high-resolution radiation scheme.We found that the stratosphere-adjusted radiative efficiencies of C2F6,CF4,and SF6 for the whole sky were 0.346,0.098,and 0.680 W m-2 ppbv-1,respectively.Radiative forcing from the industrial revolution to 2005 was 0.001,0.007,and 0.004 W m-2,re-spectively;and was predicted to rise to 0.008,0.036,and 0.037 W m-2,respectively,by 2100,according to emission scenarios provided by the IPCC.The GWPs of C2F6,CF4,and SF6 are 17035,7597,and 31298,respectively,for a time horizon of 100 years relative to CO2.Their GTPs of pulse and sustained emissions,GTPP and GTPS,are 22468,10052,and 40935 and 16498,7355,and 30341,respectively,for a 100-year time horizon. | ZHANG Hua WU JinXiu SHEN ZhongPing | 2011 | Science China Earth Sciences2011，54，5： | 8 |
| 2 | Elevated plasma levels of selective cytokines in COVID-19 patients reflect viral load and lung injury显示文摘A recent outbreak of pneumonia in Wuhan,China was found to be caused by a 2019 novel coronavirus(2019-nCoV or SARS-CoV-2 or HCoV-19).We previously reported the clinical features of 12 patients with2019-n Co V infections in Shenzhen,China.To further understand the pathogenesis of COVID-19 and find better ways to monitor and treat the disease caused by 2019-n Co V,we measured the levels of 48 cytokines in the blood plasma of those 12 COVID-19 patients.Thirty-eight out of the 48 measured cytokines in the plasma of 2019-n Co V-infected patients were significantly elevated compared to healthy individuals.Seventeen cytokines were linked to 2019-nCoV loads.Fifteen cytokines,namely M-CSF,IL-10,IFN-α2,IL-17,IL-4,IP-10,IL-7,IL-1 ra,G-CSF,IL-12,IFN-γ,IL-1α,IL-2,HGF and PDGF-BB,were strongly associated with the lung-injury Murray score and could be used to predict the disease severity of2019-n Co V infections by calculating the area under the curve of the receiver-operating characteristics.Our results suggest that 2019-nCoV infections trigger extensive changes in a wide array of cytokines,some of which could be potential biomarkers of disease severity of 2019-n Co V infections.These findings will likely improve our understanding of the immunopathologic mechanisms of this emerging disease.Our results also suggest that modulators of cytokine responses may play a therapeutic role in combating the disease once the functions of these elevated cytokines have been characterized. | Yingxia Liu Cong Zhang Fengming Huang Yang Yang Fuxiang Wang Jing Yuan Zheng Zhang Yuhao Qin Xiaoyun Li Dandan Zhao Shunwang Li Shuguang Tan Zhaoqin Wang Jinxiu Li Chenguang Shen Jianming Li Ling Peng Weibo Wu Mengli Cao Li Xing Zhixiang Xu Li Chen Congzhao Zhou William J Liu Lei Liu Chengyu Jiang | 2020 | National Science Review2020，7，6： | 6 |
| 3 | Molybdenum Nanoscrews:A Novel Non-coinage-Metal Substrate for Surface-Enhanced Raman Scattering显示文摘For the first time, Mo nanoscrew was cultivated as a novel non-coinage-metal substrate for surface-enhanced Raman scattering(SERS). It was found that the nanoscrew is composed of many small screw threads stacking along its length direction with small separations. Under external light excitation, strong electromagnetic coupling was initiated within the gaps, and many hot-spots formed on the surface of the nanoscrew, which was confirmed by high-resolution scanning near-field optical microscope measurements and numerical simulations using finite element method. These hotspots are responsible for the observed SERS activity of the nanoscrews. Raman mapping characterizations further revealed the excellent reproducibility of the SERS activity. Our findings may pave the way for design of low-cost and stable SERS substrates. | Di An Yan Shen Jinxiu Wen Zebo Zheng Jun Chen Juncong She Huanjun Chen Shaozhi Deng Ningsheng Xu | 2017 | Nano-Micro Letters2017，9，1： | 1 |
| 4 | Laboratory Diagnosis and Monitoring the Viral Shedding of SARS-CoV-2 Infection显示文摘The worldwide epidemic of coronavirus disease 2019(COVID-19)is ongoing.Rapid and accurate detection of the causative virus SARSCoV-2 is vital for the treatment and control of COVID-19.In this study,the comparative sensitivity of different respiratory specimen types were retrospectively analyzed using 3,552 clinical samples from 410 COVID-19 patients confirmed by Guangdong CDC(Center for Disease Control and Prevention).Except for bronchoalveolar lavage fluid(BALF),the sputum possessed the highest positive rate(73.4%–87.5%),followed by nasal swabs(53.1%–85.3%)for both severe and mild cases during the first 14 days after illness onset(d.a.o.).Viral RNA could be detected in all BALF samples collected from the severe group within 14 d.a.o.and lasted up to 46 d.a.o.Moreover,although viral RNA was negative in the upper respiratory samples,it was also positive in BALF samples in most cases from the severe group during treatment.Notably,no viral RNA was detected in BALF samples from the mild group.Despite typical ground-glass opacity observed via computed tomographic scans,no viral RNA was detected in the first three or all upper respiratory tract specimens from some COVID-19 patients.In conclusion,sputum is most sensitive for routine laboratory diagnosis of COVID-19,followed by nasal swabs.Detection of viral RNA in BALF improves diagnostic accuracy in severe COVID-19 patients. | Yang Yang Minghui Yang Jing Yuan Fuxiang Wang Zhaoqin Wang Jinxiu Li Mingxia Zhang Jinli Wei Ling Peng Gary Wong Haixia Zheng Weibo Wu Chenguang Shen Mingfeng Liao Kai Feng Jianming Li Qianting Yang Juanjuan Zhao Lei Liu Yingxia Liu | 2020 | The Innovation2020，1，3： | 1 |
| 5 | Porous Fe-Mn-O nanocomposites:Synthesis and supercapacitor electrode application显示文摘Transition metal oxide micro-/nanostructures demonstrate high potential applications in energy storage devices. Here, we report a facile synthesis of highly homogeneous oxide composites with porous structure via a coordination polymer precursor, which was prepared with the assistance of tartaric acid.The typical product, Fe-Mn-O composite was demonstrated here. The obtained Fe-Mn-O product was systemically characterized by X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy, elemental mapping analysis, and X-ray photoelectron spectroscopy. It was demonstrated that the Fe-Mn-O nanocomposite shows interconnected porous structure, in which iron,manganese, and oxygen are uniformly distributed. In addition, the Fe-Mn-O nanocomposite was then fabricated as capacitor electrodes. Operating in an aqueous neutral solution, the Fe-Mn-O composite electrodes showed an wide working potential window from 0.2 to 1.0 V(vs. SCE), and a specific capacitance of 86.7 Fg^(-1)or 0.4 Fcm^(-2)at a constant current density of 1 Ag^(-1)with good cycle life. This study offers a new precursor approach to prepare porous metal oxide composites, which would be applied in energy-storage/conversion devices, catalysts, sensors, and so on. | Guoxing Zhu Jing Yang Yuanjun Liu Xulan Xie Zhenyuan Ji Jinxiu Yin Xiaoping Shen | 2016 | Progress in Natural Science:Materials International2016，26，3： | 0 |

| 7 | Modularly designed peptide-based nanomedicine inhibits angiogenesis to enhance chemotherapy for post-surgical recurrence of esophageal squamous cell carcinomas显示文摘Traditional surgical treatment is difficult to thoroughly remove esophageal squamous cell carcinomas(ESCC),postoperative recurrence caused by residual tumor cells is a critical factor in the poor prognosis.Since surgical resection promotes the local angiogenesis at the tumor site,further exacerbating the proliferation and invasion of residual tumor cells,it is urgent to inhibit angiogenesis after surgery.Here,a functional peptide-based nanomedicine was obtained from peptide–drug conjugates,which are composed of a hydrophilic targeting motif(vascular endothelial growth factor family and their receptors(VEGFR)targeting peptide for anti-angiogenesis),an ester-linked hydrophobic oridonin(ORI).The nanomedicine exhibits esterase-catalyzed disassembly and drug release,significantly enhanced the anti-tumor efficacy of chemotherapeutics in a postoperative tumor recurrence model through synergistic anti-angiogenic strategies.This study provides an integrated solution for anti-angiogenesisaugmented chemotherapy and demonstrates the encouraging potential for postoperative treatment. | Yingqiu Qi Jinxiu Shen Chen Liu Anni Du Mengdie Chen Xiaocao Meng Hui Wang Saiyang Zhang Lirong Zhang Zhongjun Li Yike Li Yale Yue Huan Min | 2023 | Nano Research2023，16，5： | 0 |
