| 1 | Downstaging and resection of hepatocellular carcinoma in patients with extrahepatic metastases after stereotactic therapy显示文摘Background:A combination of tyrosine kinase inhibitors(TKIs)and anti-PD-1 antibodies with local regional therapy has elicited yield substantial clinical benefits in patients who have hepatocellular carcinoma(HCC)with extrahepatic metastases.Using this treatment strategy to convert HCC patients with extrahepatic metastases from unresectable to resectable has not yet been reported.Methods:Consecutive hepatocellular carcinoma patients with extrahepatic metastases who received first-line therapy with a combination of TKIs and anti-PD-1 antibodies and at least one local regional therapy were analysed.Results:Nine patients with localized disease who received first-line systemic therapy were enrolled.At baseline,all of them had oligometastatic disease,namely,Barcelona Clinic Liver Cancer stage C(or Chinese Liver Cancer stage IIIB).The most common treatment administered was lenvatinib plus anti-PD-1 antibody and transarterial chemoembolization,and the median time span from systemic therapy to surgery was 3.2(IQR,2.8-6.2)months.Three patients achieved a pathological complete response.Six patients underwent laparoscopic surgery,and the other 3 patients underwent open surgery.After a median follow-up of 10.2(IQR,8.6-20.0)months,7 patients survived without disease recurrence,and 2 experienced tumour recurrence.All patients had any-grade AEs,and 55.6%of the patients experienced grade 3 AEs.Fatigue was the most common AE,followed by elevated aminotransferase levels and hypertension.Conclusions:Stereotactic therapy is a feasible conversion therapy for HCC patients with extrahepatic metastases to become resectable.This is the first study to analyse therapeutic outcomes of patients receiving these therapies for HCC with extrahepatic metastases. | Xiaobo Yang Haifeng Xu Bangyou Zuo Xu Yang Jin Bian Junyu Long Dongxu Wang Junwei Zhang Cong Ning Yanyu Wang Ziyu Xun Yunchao Wang Xin Lu Yilei Mao Xinting Sang Haitao Zhao | 2021 | Hepatobiliary Surgery and Nutrition2021，10，4： | 17 |
| 2 | One-Pot Synthesis and Strong Near-Infrared Upconversion Luminescence of Poly(acrylic acid)-Functionalized YF3:Yb^(3+)/Er^(3+) Nanocrystals显示文摘This paper describes the synthesis of new upconverting luminescent nanoparticles that consist of YF_(3):Yb^(3+)/Er^(3+)functionalized with poly(acrylic acid)(PAA).Unlike the upconverting nanocrystals previously reported in the literature that emit visible(blue-green-red)upconversion fluorescence,these as-prepared nanoparticles emit strong near-infrared(NIR,831 nm)upconversion luminescence under 980 nm excitation.Scanning electron microscopy,transmission electron microscopy,and powder X-ray diffraction were used to characterize the size and composition of the luminescent nanocrystals.Their average diameter was about 50 nm.The presence of the PAA coating was confirmed by infrared spectroscopy.The particles are highly dispersible in aqueous solution due to the presence of carboxylate groups in the PAA coating.By carrying out the synthesis in the absence of PAA,YF_(3):Yb^(3+)/Er^(3+)nanorice materials were obtained.These nanorice particles are larger(~700 nm in length)than the PAA-functionalized nanoparticles and show strong typical visible red(668 nm),rather than NIR(831 nm),upconversion fluorescence.The new PAA-coated luminescent nanoparticles have the pottential be used in a variety of bioanalytical and medical assays involving luminescence detection and fluorescence imaging,especially in vivo fluorescence imaging,due to the deep penetration of NIR radiation. | Leyu Wang Yi Zhang Yanyu Zhu | 2010 | Nano Research2010，3，5： | 13 |
| 3 | Proteomic analysis of human epithelial ovarian cancer xenografts in immunodeficient mice exposed to chronic psychological stress显示文摘This work aims at comparing alterations in the proteomes of human epithelial ovarian cancer xenografts between stressed and non-stressed immunodeficient mice as well as exploring the molecular mechanisms linking chronic psychological stress to ovarian cancer oncogenesis and progression.SK-OV-3 cells were injected subcutaneously into nude mice.The stress group was subjected to a chronic physical restraint protocol for 6 h on 35 consecutive days,while the control group was unrestrained.All mice were sacrificed on day 36 after SK-OV-3 cell injection,and tumors were excised.Tumor tissues were processed for 2D gel electrophoresis,mass spectrometry(nanoUPLC-ESI-MS/MS) and Western blotting.The expression of 20 proteins was found to be significantly altered between the stress and control groups,of which 14 were up-regulated,five were down-regulated,and one protein was found only in the stress group.All proteins were identified by UPLC-ESI-MS/MS,and Western blotting results were consistent with those of proteomic methods.The present results provide new evidence relating to the molecular mechanism underlying the relationship between psychological stress and tumor progression. | GAO Jun GAO GuoLan ZHANG YanYu WANG Fen | 2011 | Science China(Life Sciences)2011，54，2： | 11 |
| 4 | Clinical characteristics and survival of 5283 esophageal cancer patients: A multicenter study from eighteen hospitals across six regions in China显示文摘Objective:This study aimed to investigate the potential determining epidemiological and clinical risk factors affecting the survival of esophageal cancer(EC)patients across multiple hospitals in China.Methods:This was a multicenter study comprising of newly diagnosed EC cases from Beijing,Hebei,Henan,Hubei,Zhejiang,and Guangdong Province of China.Their baseline characteristics and treatment methods data were collected from their medical records.The EpiData software was used for data quality control.The Kaplan-Meier method was used to estimate their overall survival(OS),and the Cox’s proportional hazard regression model was used to estimate hazard ratios(HR)and 95%confidence interval(CI).Results:The 3-and 5-year OS rates of the 5283 investigated EC patients were 49.98%and 39.07%,respectively.Their median survival was 36.00 months.The median survival time of females was longer than that of males(females vs.males:45.00 vs.33.00,P<0.001).The 5-year OS rate of patients who never-smoked was higher than that of smokers(never-smokers vs smokers:40.73%vs.37.84%,P=0.001).There was no significant difference in the 5-year OS rate between drinkers and never-drinkers(drinkers vs never-drinkers:34.22%vs.29.65%,P=0.330).In multivariate analysis,pathological stage(stage II:HR=1.80,95%CI=1.40-2.31;stage III:HR=2.62,95%CI=2.06-3.34;stage IV:HR=3.90,95%CI=2.98-5.09),poor differentiation/undifferentiated(HR=1.34,95%CI=1.11-1.63),not married status(HR=2.45,95%CI=1.49-4.04),production and service personnel(HR=1.36,95%CI=1.01-1.83)and farming/fishing(HR=1.40,95%CI=1.12-1.76)were independent prognostic risk factors for poor EC survival.Tumors in the thoracic or abdominal part of the esophagus,female and family history of any cancer were independent factors predictive of a good EC OS.Conclusion:Gender,marital status,occupation,family history of any cancer,tumor topographical site,differentiation status,and pathological stage were associated with the survival rate of EC.This study reveals important clinical characteristics of esophageal cancer patients in China and provides helpful information for their clinical management and surveillance. | Yutong He Di Liang Lingbin Du Tiantian Guo Yanyu Liu Xibin Sun Ning Wang Min Zhang Kuangrong Wei Baoen Shan Wanqing Chen | 2020 | Cancer Communications2020，40，10： | 8 |
| 5 | Light absorption properties and potential sources of brown carbon in Fenwei Plain during winter 2018–2019显示文摘A distinctive kind of organic carbon aerosol that could absorb ultraviolet-visible radiation is called brown carbon(Br C),which has an important positive influence on radiative budget and climate change.In this work,we reported the absorption properties and potential source of Br C based on a seven-wavelength aethalometer in the winter of 2018–2019 at an urban site of Sanmenxia in Fenwei Plain in central China.Specifically,the mean value of Br C absorption coefficient was 59.6±36.0 Mm^(-1) at 370 nm and contributed 37.7%to total absorption,which made a significant impact on visibility and regional environment.Absorption coefficients of Br C showed double-peak pattern,and Br C had shown small fluctuations under haze days compared with clean days.As for the sources of Br C,Br C absorption coefficients expressed strong correlations with element carbon aerosols and primary organic carbon aerosols,indicating that most of Br C originated from primary emissions.The linear correlations between trace metal elements(K,As,Fe,Mn,Zn,and Pb)and Br C absorption coefficients further referred that the major sources of Br C were primary emissions,like coal burning,biomass burning,and vehicle emissions.The moderate relationship between Br C absorption coefficients and secondary organic aerosols suggested that secondary production of Br C also played an important role.The 120 hr backward air mass trajectories analysis and concentration-weighted trajectories analysis were also used to investigate potential sources of Br C in and around this area,which inferred most parts of Br C were derived from local emissions. | Wenyu Zhang Weigang Wang Jie Li Shuangliang Ma Chaofan Lian Kun Li Bo Shi Mingyuan Liu Yanyu Li QingQing Wang Yele Sun Shengrui Tong Maofa Ge | 2021 | Journal of Environmental Sciences2021，33，4： | 6 |
| 6 | A Phytophthora capsid Effector Targets ACD11 Binding Partners that Regulate ROS-Mediated Defense Response in Arabidopsis显示文摘Reactive oxygen species (ROS) play a vital role in plant immune response, but the genes involved in the regulation of ROS are scantily reported. Phytophthora pathogens produce a large number of effectors to promote infection, but the modes of action adopted are largely unknown. Here, we report that RxLR207 could activate ROS-mediated cell death in Nicotiana benthamiana and was essential for virulence of P. capsici. We found that this effector targeted BPA1 (binding partner of ACD11) and four members of BPLs (BPAl-Like proteins)in Arabidopsis, and the bpa1 and bpl mutants had enhanced ROS accumulation and cell death under biotic or abiotic stresses. Furthermore, we showed that BPA1 and several BPLs functioned redundantly in plant immunity to P. capsici. We discovered that BPA1 and all six BPLs interacted with ACD11, and stabilization of ACD11 was impaired in the bpa 1, bpl2, bpl3, and bpl4 mutants. RxLR207 could promote the degradation of BPA1, BPL1, BPL2, and BPL4 to disrupt ACD11 stabilization in a 26S proteasome-dependent manner. Taken together, these fin dings indicate the important roles of Arabidopsis BPA1 and its homologs in ROS homeostasis and defense response, highlighting the usefulness of a pathogen effector-directed approach as a promising strategy for the discovery of novel plant immune regulators. | Qi Li Gan Ai Danyu Shen Fen Zou Ji Wang Tian Bai Yanyu Chen Shutian Li Meixiang Zhang Maofeng Jing Daolong Dou | 2019 | Molecular Plant2019，12，4： | 5 |
| 7 | Efficacy of water fraction from Dioscorea cirrhosa on oxidative stress and apoptosis in H9c2 cardiomyocytes induced by H2O2显示文摘OBJECTIVE:To investigate the efficacy of water fraction from Dioscorea cirrhosa(WF)on oxidative damage and apoptosis of cardiomyocytes induced by H2O2,and to study its mechanism.METHODS:Cell viability was measured by the MST assay kit.The content of malondialdehyde(MDA),release of lactate dehydrogenase(LDH)and activity of catalase(CAT)and superoxide dismutase(SOD)were detected by biochemical kit.The content of reactive oxygen species(ROS)was assessed by nonfluorescent probe 2′,7′-dichlorofluorescin diacetate(DCFH-DA).JC-1 was used to analyze the mitochondrial membrane potential(mtΔΨ)and Annexin-V-FITC/PI staining was applied to assess apoptosis of H9c2 by flow cytometry.Moreover,the expression of B-cell lymphoma-2(Bcl-2),Bcl-2-associated X(Bax),caspase-3,caspase-9,cleaved-caspase-3 and cleaved-caspase-9 proteins was determined by western blot analysis.RESULTS:WF increased cell viability and decreased LDH leakage in H9c2 cells exposed to H2O2.WF treatment decreased ROS and MDA level,enhanced SOD and CAT activities,improved mtΔΨand inhibited apoptosis.Western blot analysis demonstrated that the ratio of Bcl-2/Bax was increased and the expression cleaved-caspase-3,caspase-3,cleaved-caspase-9 and caspase-9 were decreased in group treated with WF.CONCLUSION:WF protects H9c2 myocardial cells on H2O2-induced oxidative stress and apoptosis by scavenging ROS,improving antioxidant capacity,protecting mitochondrial and regulating the proteins expression related to apoptosis. | LIU Chunhua PAN Jie WANG Aimin LAN Yanyu LI Yongjun LU Yuan SUN Jia WANG Yonglin LIU Ting LU Dingyan YOU Jingrui | 2021 | Journal of Traditional Chinese Medicine2021，41，1： | 4 |
| 8 | Sb_(2)WO_(6)/BiOBr 2D nanocomposite S-scheme photocatalyst for NO removal显示文摘Photocatalysis technology is an efficient method for removing nitrogen oxides at low concentrations.Herein,dimension-matched Sb_(2)WO_(6)/BiOBr photocatalysts were synthesized at room temperature via precipitation-deposition way.Under visible light irradiation,the as-obtained Sb_(2)WO_(6)/Bi OBr photocatalysts showed enhanced photocatalytic performance compare with the pure Sb_(2)WO_(6) and BiOBr for removal of NO.The optimal ratio for photocatalytic performance of Sb_(2)WO_(6)/BiOBr composite was found to be 30 wt.%of Sb_(2)WO_(6),which showed excellent recycling property even after 5 runs.Moreover,in situ DRIFT was carried out to reveal the time-dependent evolution of reaction intermediates during photocatalytic NO oxidation.The probable photocatalytic mechanism was considered based on the active species capture experiments.The enhanced photocatalytic performance for the Sb_(2)WO_(6)/BiOBr composite photocatalyst perhaps is attributed to the interaction between BiOBr and Sb2WO6 and S-scheme charge transfer path. | Yanyu Wang Kai Wang Jinlong Wang Xiaoyong Wu Gaoke Zhang | 2020 | Journal of Materials Science & Technology2020，56，21： | 4 |
| 9 | Multidrug-resistant Proteus mirabilis isolates carrying blaOXA-1 and blaNDM-1 from wildlife in China:increasing public health risk显示文摘The emergence of multidrug resistance(MDR)in Proteus mirabilis clinical isolates is a growing public health concern and has serious implications for wildlife.What is the role of wildlife has been become one of the hot issues in disseminating antimicrobial resistance.Here,54 P.mirabilis isolates from 12 different species were identified.Among them,25 isolates were determined to be MDR by profile of antimicrobial susceptibility;10 MDR P.mirabilis isolates were subjected to comparative genomic analysis by whole genome sequencing.Comprehensive analysis showed that chromosome of P.mirabilis isolates mainly carries multidrug-resistance complex elements harboring resistance to carbapenem genes blaOXA-1,blaNDM-1,and blaTEM-1.Class I integron is the insertion hotspot of IS26;it can be inserted into type I integron at different sites,thus forming a variety of multiple drug resistance decision sites.At the same time,Tn21,Tn7,and SXT/R391 mobile elements cause widespread spread of these drug resistance genes.In conclusion,P.mirabilis isolates from wildlife showed higher resistance to commonly used clinic drugs comparing to those from human.Therefore,wild animals carrying MDR clinical isolates should be paid attention to by the public health. | Qian KANG Xue WANG Jianan ZHAO Zhihui LIU Fang JI Han CHANG Jianchun YANG Shijia HU Ting JIA Xiaojia WANG Jiagui TANG Guoying DONG Guocheng HU Jing WANG Yanyu ZHANG Jianhua QIN Chengmin WANG | 2021 | Integrative Zoology2021，16，6： | 4 |
| 10 | Vertical Evolution of Boundary Layer Volatile Organic Compounds in Summer over the North China Plain and the Differences with Winter显示文摘The vertical observation of volatile organic compounds(VOCs)is an important means to clarify the mechanisms of ozone formation.To explore the vertical evolution of VOCs in summer,a field campaign using a tethered balloon during summer photochemical pollution was conducted in Shijiazhuang from 8 June to 3 July 2019.A total of 192 samples were collected,23 vertical profiles were obtained,and the concentrations of 87 VOCs were measured.The range of the total VOC concentration was 41-48 ppbv below 600 m.It then slightly increased above 600 m,and rose to 58±52 ppbv at 1000 m.The proportion of alkanes increased with height,while the proportions of alkenes,halohydrocarbons and acetylene decreased.The proportion of aromatics remained almost unchanged.A comparison with the results of a winter field campaign during 8-16 January 2019 showed that the concentrations of all VOCs in winter except for halohydrocarbons were more than twice those in summer.Alkanes accounted for the same proportion in winter and summer.Alkenes,aromatics,and acetylene accounted for higher proportions in winter,while halohydrocarbons accounted for a higher proportion in summer.There were five VOC sources in the vertical direction.The proportions of gasoline vehicular emissions+industrial sources and coal burning were higher in winter.The proportions of biogenic sources+long-range transport,solvent usage,and diesel vehicular emissions were higher in summer.From the surface to 1000 m,the proportion of gasoline vehicular emissions+industrial sources gradually increased. | Shuang WU Guiqian TANG Yinghong WANG Rong MAI Dan YAO Yanyu KANG Qinglu WANG Yuesi WANG | 2021 | Advances in Atmospheric Sciences2021，38，7： | 3 |

| 17 | Therapeutic strategies of glioblastoma (GBM):The current advances in the molecular targets and bioactive small molecule compounds显示文摘Glioblastoma(GBM)is the most common aggressive malignant tumor in brain neuroepithelial tumors and remains incurable.A variety of treatment options are currently being explored to improve patient survival,including small molecule inhibitors,viral therapies,cancer vaccines,and monoclonal antibodies.Among them,the unique advantages of small molecule inhibitors have made them a focus of attention in the drug discovery of glioblastoma.Currently,the most used chemotherapeutic agents are small molecule inhibitors that target key dysregulated signaling pathways in glioblastoma,including receptor tyrosine kinase,PI3K/AKT/mTOR pathway,DNA damage response,TP53 and cell cycle inhibitors.This review analyzes the therapeutic benefit and clinical development of novel small molecule inhibitors discovered as promising anti-glioblastoma agents by the related targets of these major pathways.Meanwhile,the recent advances in temozolomide resistance and drug combination are also reviewed.In the last part,due to the constant clinical failure of targeted therapies,this paper reviewed the research progress of other therapeutic methods for glioblastoma,to provide patients and readers with a more comprehensive understanding of the treatment landscape of glioblastoma. | Hui Liu Weimin Qiu Tianyu Sun Lei Wang Chenxi Du Yanyu Hu Wenyuan Liu Feng Feng Yao Chen Haopeng Sun | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 3 |
| 18 | Prospect of China's ambient air quality standards显示文摘Ambient air quality standards are the core strategic goal of ambient air quality management.Countries worldwide have given importance to research on the development of ambient air quality standards.To understand the history of the development of China’s ambient air quality standards,this study analyzed the background associated with all previous formulations and revisions of the standards,classification of functional areas,standard grading,pollutants,and evolution of the standard limits over the past 40 years.The results show that since the initial release of the“Ambient Air Quality Standard”by China in 1982,it has been supplemented once,revised twice,and modified twice.The first ambient air quality standard specified the standard limits of six pollutants commonly found in ambient air.With the development of ambient air quality management,the number of pollutants has increased to ten.Since the release of the“Ambient Air Quality Standards”in 2012,the ambient air quality in China has significantly improved.However,the proportion of cities meeting these standards is still low.At present,China is suitably positioned to make the standards associated with 24 hr SO2concentrations more stringent such that it meets the values defined in the World Health Organization(WHO)interim target-2 and the WHO air quality guideline(AQG).We further suggested that the SO2standard should be revised promptly.Simultaneously,regions with a relatively high proportion of cities meeting the standard are encouraged to introduce more stringent interim target limits in due course to manage the local ambient air quality. | Zongshuang Wang Yufei Tan Min Guo Miaomiao Cheng Yanyue Gu Siyu Chen Xuefang Wu Fahe Chai | 2023 | Journal of Environmental Sciences2023，，1： | 2 |
| 19 | One-Pot Synthesis of Hierarchically Nanoporous SSZ-13 for Conversion of Methanol to Olefins显示文摘The main disadvantage of microporous SSZ-13 catalyst used in the methanol to olefins(MTO) process is its rapid deactivation due to its relatively low coke resistance. Meanwhile, the hierarchical zeolites usually exhibit improved catalytic stability thanks to their better mass transfer ability. Herein, the hierarchically nanoporous SSZ-13 zeolites were one-pot synthesized by using N,N,N-trimethyl-1-adamantanammonium hydroxide as a microporous structure directing agent and C_(18)H_(37) N^+(CH_3)_2 C_6H_(12) N^+(CH_3)_2 C_6 H_(13)(Br^-)_2(hereinafter abbreviated as C_(18-6-6) Br_2) as a mesoporogen. The hierarchically nanoporous SSZ-13 catalyst was characterized by XRD, N_2 physisorption, SEM, TEM, TG-DTG, ^(27) Al and ^(29) SiNMR spectroscopy and NH_3-TPD techniques. The results showed that the hierarchical SSZ-13 zeolite synthesized in the presence of the C_(18-6-6) Br_2 surfactant exhibits aggregates of primary nanocrystals and contains the well-developed mesopores and excellent acidity. Compared to its conventional counterpart, the hierarchical SSZ-13 zeolite has longer catalytic lifetime and higher selectivity for ethylene and propylene in the MTO reaction, which can be attributed to the synergistic effect of their good acidity and improved diffusion properties resulted from the hierarchical pore structure. | Li Yuping Wang Yanyue Zhang Yi Liu Rui Li Xiaofeng Dou Tao | 2017 | China Petroleum Processing & Petrochemical Technology2017，19，3： | 2 |
| 20 | Electrolyte-mediated dense integration of graphene-MXene films for high volumetric capacitance flexible supercapacitors显示文摘High conductivity two-dimensional(2D)materials have been proved to be potential electrode materials for flexible supercapacitors because of its outstanding chemical and physical properties.However,electrodes based on 2D materials always suffer from limited electrolyte-accessible surface due to the restacking of the 2D sheets,hindering the full utilization of their surface area.In this regard,an electrolyte-mediated method is used to integrate dense structure reduced graphene oxide/MXene(RGM)-electrolyte composite films.In such composite films,reduced graphene oxide(RGO)and MXene sheets are controllable assembly in compact layered structure with electrolyte filled between the layers.The electrolyte layer between RGO and MXene sheets forms continuous ion transport channels in the composite films.Therefore,the RGM-electrolyte composite films can be used directly as self-supporting electrodes for supercapacitors without additional conductive agents and binders.As a result,the composite films demonstrate enhanced volumetric specific capacity,improved volumetric energy density and higher power density compared with both pure RGO electrode and porous composite electrode prepared by traditional methods.Specifically,when the mass ratio of MXene is 30%,the electrode delivers a volumetric specific capacity of 454.9 F·cm^(−3) with a high energy density of 39.4 Wh·L^(−1).More importantly,supercapacitors based on the composite films exhibit good flexibility electrochemical performance.The investigation provides a new approach to synthesize dense structure films based on 2D materials for application in high volumetric capacitance flexible supercapacitors. | Min Zhang Jun Cao Yi Wang Jia Song Tianci Jiang Yanyu Zhang Weimeng Si Xiaowei Li Bo Meng Guangwu Wen | 2021 | Nano Research2021，14，3： | 2 |
