| 1 | China National Medical Products Administration approval summary:anlotinib for the treatment of advanced non-small cell lung cancer after two lines of chemotherapy显示文摘Background:On May 8,2018,the China National Medical Products Administration(NMPA)approved anlotinib,an orally administered anti-angiogenesis inhibitor,for the treatment of patients with advanced non-small cell lung can-cer(NSCLC)who have progressed after treatment with two or more lines of prior systemic chemotherapy.Main body of the abstract:China NMPA reviewed and inspected a regional double-blinded,placebo-controlled,Phase III trial comparing the overall survival(OS)of NSCLC patients between the anlotinib and placebo arms.A total of 437 patients were randomized(2:1)to receive either anlotinib(n=294)or placebo(n=143)once daily on a 2-week on and 1-week off schedule.Patients with epidermal growth factor receptor(EGFR)or activating anaplastic lymphoma kinase(ALK)genomic tumor aberrations should have disease progression on NMPA-approved therapy.Anlotinib is the first NMPA-approved drug for patients with advanced NSCLC who have progressed on at least two lines of prior systemic chemotherapies in China.The approval was based on a statistically and clinically significant improvement in median OS with anlotinib(9.46 months)compared with placebo[6.37 months;hazard ratio(HR])=0.70,95%confidence interval(CI)=0.55-0.89;two-sided log-rank P=0.002].The confirmed objective response rate(ORR)was 9.2%in the anlotinib arm and 0.7%in the placebo arm.The median duration of response(DoR)was 4.83 months,with a 95%CI of 3.31-6.97 months.The toxicity profile of anlotinib was consistent with that of known anti-angiogenesis inhibitors.Common adverse drug reactions(ADRs)in anlotinib-treated patients included hypertension(67.4%),hand-foot syndrome(43.9%),hemoptysis(14.0%),thyroid stimulating hormone(TSH)elevation(46.6%),and corrected QT interval(QTc)prolongation(26.2%).Short conclusion:Anlotinib demonstrated a clinically significant OS prolongation as a novel therapeutic option for advanced or metastatic NSCLC following at least two lines of chemotherapy. | Ming Zhou Xiaoyuan Chen Hong Zhang Lin Xia Xin Tong Limin Zou Ruimin Hao Jianhong Pan Xiao Zhao Dongmei Chen Yuanyuan Song Yueli Qi Ling Tang Zhifang Liu Rong Gao Yuankai Shi Zhimin Yang | 2019 | Cancer Communications2019,39,1: | 35 |
| 2 | Highly effective removal of Methylene Blue using functionalized attapulgite via hydrothermal process显示文摘Attapulgite(APT) has been frequently used for the adsorptive removal of dyes from aqueous solution owing to its unique one-dimensional nanoscale structure and low-cost, abundant,eco-friendly advantages. In this work, APT was functionalized under mild hydrothermal condition using chloroacetic acid(CA) with \COOH functional groups to improve its adsorption properties. The effect of hydrothermal modification on the microstructure and physicochemical features of APT was investigated by Fourier transform infrared spectroscopy, X-ray diffraction and Field-emission scanning electron microscopy analyses. The effects of hydrothermal reaction parameters on the adsorption properties of modified APT were intensively investigated. It was revealed that the rearrangement of crystal structure and the surface functionalization of APT with \COOH groups cause the surprising increase of adsorption capability for Methylene Blue(MB). The removal ratio of raw APT for MB is only 59.52%, while modified APT could almost completely remove MB in the 200 mg/L of MB solution with a removal ratio of 99.8%. The adsorption kinetics fitted pseudo second-order kinetic model, and the adsorption isotherm could be described with Langmuir isotherm model very well. The hydrogen-bonding interaction, electrostatic attraction and chemical association are the main driving force for the adsorption process. | Zhifang Zhang Wenbo Wang Aiqin Wang | 2015 | Journal of Environmental Sciences2015,27,7: | 18 |
| 3 | Functional analysis of the larval serum protein gene promoter from silkworm,Bombyx mori.显示文摘The regulation region of larval serum protein gene, Bombyx mori. (BmLSP), consisting of the first intron, the first exon, the central promoter region and 5′-upstream region, is cloned from genomic DNA from the silkworm va-riety of Suju譓inghu. Using PCR and restriction endonu-clease methods, a series of luciferase reporter plasmids, driven by different length of BmLSP promoters, are con-structed. Via the transient expression system in BmN cells, the effects of the regulation elements and foreign insect hor-mones on the BmLSP promoter activity are investigated. The results demonstrate that the promoter activity of BmLSP is 5.8- or 4.4-fold higher than that of BmLSPs whose first in-tron or the element in 5′-upstream region harboring the homologous sequence with the first intron of light-chain fib-roin gene (EHIF) is deleted, respectively, suggesting that both the first intron and EHIF contain the main positive cis-acting elements. However, the inactive mariner transposable ele-ment (MTE) in 5′-upstream region presents a negative effect. Furthermore, the effects of juvenile hormone analogue (JHA) on the BmLSP promoter activity show a typical dose-dependent manner, that is, low concentration treat-ments increase the BmLSP promoter activity and high con-centration treatments decrease it. Meanwhile, insect ecdy-sone (MH) treatments present no significant effect. | TANG Shunming, YI Yongzhu, SHEN Xingjia, ZHANG Zhifang, LI Yiren & HE Jialu Key Laboratory of Silkworm Biotechnology, Ministry of Agriculture, Sericultural Research Institute, Chinese Academy of Agricultural Sci-ences, Zhenjiang 212018, China Correspondence should be addressed to Zhang Zhifang (e-mail: zjsbsri@ public.zj.js.cn) | 2003 | Chinese Science Bulletin2003,48,23: | 13 |

| 6 | Geochemical environmental changes and dinosaur extinction during the Cretaceous-Paleogene (K/T) transition in the Nanxiong Basin, South China: Evidence from dinosaur eggshells显示文摘The complex patterns of trace elements including Ir and isotope distributions in the three K/T sections of the Nanxiong Basin prove the existence of two environmental events in the latest Cretaceous and earliest Paleocene. The first geochemical environmental event occurred at about 2 Ma prior to the K/T boundary interval, where the dinosaur diversity was hardly reduced, except that a number of patho-logical eggshells appeared. The second one was larger and occurred just at and near the Creta-ceous-Paleogene (K/T) boundary. The extinction of the dinosaurs spread out within 250 ka with major extinction beginning at the boundary interval. This is even later than their extinction in Montana, North America and in India. The cause of the dinosaur extinction may be the result of a complex multiple events brought about by the coincidence of global environment change marked by multiple Ir and δ 18O anomalies, and environmental poisoning characterized by other trace elements derived from the local source. Successive short- and long-term conditions of geochemically induced environmental stress negatively affected the reproductive process and thus contributed to the extinction of the dinosaurs. | ZHAO ZiKui MAO XueYing CHAI ZhiFang YANG GaoChuang ZHANG FuCheng YAN Zheng | 2009 | Chinese Science Bulletin2009,54,5: | 12 |
| 7 | Rational secret sharing as extensive games显示文摘The threat that comes from previously used punishment strategies in rational secret sharing is weakened because the punishment somtimes also causes loss to the punisher himself.In this paper,we first model 2-out-of-2 rational secret sharing in an extensive game with imperfect information,and then provide a strategy for achieving secret recovery in this game.Moreover,we prove that the strategy is a sequential equilibrium which means after any history of the game no player can benefit from deviations so long as the other players stick to the strategy.In particular,when a deviation is detected,the punishment executed by the punisher is still his optimal option.Therefor,by considering rational secret sharing as an extensive game,we design punishment strategies that effectively punish the deviants and meanwhile guarantee punishers' benefit.Hence,these punishments are more credible than previous ones.Except assuming the existence of simultaneous channels,our scheme can have dealer off-line and extend to the t-out-of-n setting,and also satisfies computational equilibria in some sense. | ZHANG ZhiFang LIU MuLan | 2013 | Science China(Information Sciences)2013,56,3: | 12 |
| 8 | Delayed drainage of aquitard in response to sudden change in groundwater level in adjacent confined aquifer: Analytical and experimental studies显示文摘The problem of the groundwater dynamics and water balance of a confined aquifer in the aquifer system has been solved in previous studies, whereas that in the aquitard adjacent to the confined aquifer has seldom been considered. In reality, the groundwater dynamics of the aquitard are closely related to the exploitation of groundwater resources, groundwater contamination, underground storage utilization and land subsidence. In this paper, an analytical solution is derived to describe the drawdown variation in the aquitard when the head in the adjacent confined aquifer declines by a constant value. The characteristics of groundwater dynamics and water balance of the aquitard are analyzed using a dimensionless analytical solution. There is obvious delayed behavior in the response of groundwater dynamics in the aquitard, which is characterized by the delay index t0. The delayed behavior in the response of groundwater dynamics is not only dependent on the properties of the aquitard, but also proportional to the square of the thickness of the aquitard. The law of the delayed release of water is described in terms of the ratio of the delayed release of water. A water balance equation for the aquitard is established. Three stages of the water balance and the corresponding characteristics are presented with the water balance curves of the aquitard. The analytical solution is given to analyze the flux per unit horizontal area of the aquitard. The hydrogeological parameters of the aquitard, namely the hydraulic conductivity, specific storativity and hydraulic diffusivity, are estimated according to type-curve fitting between the analytical solution and observed flux. The parameters are identified and validated in an experiment. | ZHOU ZhiFang GUO QiaoNa DOU Zhi | 2013 | Chinese Science Bulletin2013,58,25: | 10 |
| 9 | IFN-γ,establishes interferon-stimulated gene-mediated antiviral state against Newcastle disease virus in chicken fibroblasts显示文摘Newcastle disease virus(NDV)causes severe economic losses through severe morbidity and mortality and poses a significant threat to the global poultry industry.Significant efforts have been made to develop novel vaccines and therapeutics;however,the interaction of NDV with the host is not yet fully understood.Interferons(IFNs),an integral component of innate immune signaling,act as the first line of defense against invading viruses.Compared with the mammalian repertoire of IFNs,limited information is available on the antiviral potential of IFNs in chickens.Here,we expressed chicken IFN-γ(chlFN-γ)using a baculovirus expression vector system,characterized its antiviral potential against NDV,and determined its antiviral potential.Priming of chicken embryo fibroblasts with chlFN-γelicited an antiviral environment in primary cells,which was mainly due to interferon-stimulated genes(ISGs).A genome-wide transcriptomics approach was used to elucidate the possible signaling pathways associated with IFN-γ-induced immune responses.RNA-sequencing(RNA-seq)data revealed significant induction of ISG-associated pathways,activated temporal expression of ISGs,antiviral mediators,and transcriptional regulators in a cascade of antiviral responses.Collectiv(e)ly,we found that IFN-γsignificantly elicited an antiviral response against NDV infection.These data provide a foundation for chlFN-γ-mediated antiviral responses and underpin functional annotation of these important chlFN-γ,-induced antiviral influencers. | Xin Yang Mehboob Arslan Xingjian Liu Haozhi Song Mengtan Du YinüLi Zhifang Zhang | 2020 | Acta Biochimica et Biophysica Sinica2020,52,3: | 9 |

| 14 | Effects of rare earth elements La and Yb on the morphological and functional development of zebrafish embryos显示文摘In recent years,with the wide applications and mineral exploitation of rare earth elements,their potential environmental and health effects have caused increasing public concern.Effect of rare earth elements La and Yb on the morphological and functional development of zebrafish embryos were studied.The embryos were exposed to La3+ or Yb3+ at 0,0.01,0.1,0.3,0.5 and 1.0 mmol/L,respectively.Early life stage parameters such as egg and embryo mortality,gastrula development,tail detachment,eyes,somite formation,circulatory system,pigmentation,malformations,hatching rate,length of larvae and mortality were investigated.The results showed La3+ and Yb3+ delayed zebrafish embryo and larval development,decreased survival and hatching rates,and caused tail malformation in a concentration-dependent way.Moreover,heavy rare-earth ytterbium led to more severe acute toxicity of zebrafish embryo than light rare-earth lanthanum. | Jun'an Cui Zhiyong Zhang Wei Bai Ligang Zhang Xiao He Yuhui Ma Yan Liu Zhifang Chai | 2012 | Journal of Environmental Sciences2012,24,2: | 8 |
| 15 | Dynamic changes in proteins during apple(Malus x domestica)fruit ripening and storage显示文摘A proteomic study,using two-dimensional polyacrylamide gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight/time-of-flight,was conducted in apple fruit(cv.‘Golden Delicious’)starting at 10 days prior to harvest through 50 days in storage.Total protein was extracted using a phenol/sodium dodecyl sulfate protocol.More than 400 protein spots were detected in each gel and 55 differentially expressed proteins(p,0.05)were subjected to matrix-assisted laser desorption/ionization time-of-flight/time-of-flight analysis.Fifty-three of these proteins were finally identified using an apple expressed sequence tag database downloaded from Genome Database for Rosaceae and placed into six categories.The categories and the percentage of proteins placed in each category were stress response and defense(49.0%),energy and metabolism(34.0%),fruit ripening and senescence(5.6%),signal transduction(3.8%),cell structure(3.8%)and protein synthesis(3.8%).Proteins involved in several multiple metabolic pathways,including glycolysis,pentose–phosphate pathway,anti-oxidative systems,photosynthesis and cell wall synthesis,were downregulated,especially during the climacteric burst in respiration and during the senescent stages of fruit development.Proteins classified as allergens or involved in cell wall degradation were upregulated during the ripening process.Some protein spots exhibited a mixed pattern(increasing to maximal abundance followed by a decrease),such as 1-aminocyclopropane-1-carboxylate oxidase,L-ascorbate peroxidase and abscisic acid response proteins.The identification of differentially expressed proteins associated with physiological processes identified in the current study provides a baseline of information for understanding the metabolic processes and regulatory mechanisms that occur in climacteric apple fruit during ripening and senescence. | Yun Shi Li Jiang Li Zhang Ruoyi Kang Zhifang Yu | 2014 | Horticulture Research2014,1,1: | 8 |

| 17 | X-ray scintillation in lead-free double perovskite crystals显示文摘Metal halide perovskites have shown great performance for various applications,including solar cells,light emitting diodes,and radiation detectors,but they still suffer from the toxicity of lead and instability.Here we report the use of lanthanide series as trivalent metals to obtain low toxicity and highly stable double perovskites(Cs_2NaLnCl_6,Ln=Tb or Eu)with high scintillation light yield.The crystals exhibit typical f-f transitions of lanthanide cations,while Cs_2NaTbCl_6exhibits strong green photoluminescence,and Cs_2NaEuCl_6exhibits red photoluminescence.Under X-ray radiations,the light yield of Cs_2NaTbCl_6reaches46600 photons MeV^(-1),much higher than that of the commercially used(Lu,Y)_2SiO_5:Ce^(3+)crystals(LYSO,28500 photons MeV^(-1)),and previously reported lead-based perovskites(14000 photons MeV^(-1)).As a new member of lead-free perovskites,lanthanide-based double perovskites open up a new route toward radiation detections and potential medical imaging. | Qingsong Hu Zhenzhou Deng Manchen Hu Anjiang Zhao Yaqi Zhang Zhifang Tan Guangda Niu Haodi Wu Jiang Tang | 2018 | Science China Chemistry2018,61,12: | 7 |
| 18 | QTL analysis of ear leaf traits in maize(Zea mays L.)under different planting densities显示文摘Modem maize varieties have become more productive than ever, owing largely to increased tolerance of high plant density. However, the genetics of ear leaf traits under different densities remains poorly understood. In this study, Zhongdan 909 recombinant inbred lines(RILs) derived from a cross between Z58 and HD568 were genotyped for 3072 single-nucleotide polymorphisms(SNPs), and phenotyped for leaf length(LL), leaf width(LW), and leaf angle(LA) of the uppermost ear leaf under three planting densities(52,500,67,500, and 82,500 plants ha-1, respectively). A genetic map was then constructed using1358 high-quality SNPs. The total length of the linkage map was 1985.2 cM and the average interval between adjacent markers 1.46 cM. With increasing density, LL and LW decreased from 63.68 to 63.02 cm and from 8.56 to 8.21 cm, respectively, while LA increased from19.42° to 19.66°. All three traits had high heritabilities, of 0.75, 0.78, and 0.84, respectively.Using inclusive composite interval mapping, 23, 25, and 17 quantitative trait loci(QTL) were detected for LL, LW, and LA, respectively. Of these, 35 were simultaneously detected under two or three plant densities, while 30 were detected under only one. Sixty-five individual QTL explained 2.41% to 16.53% of phenotypic variation, while eight accounted for >10%.These findings will help us understand the genetic basis of leaf traits in maize as well as the response of maize to increased plant density. | Hongwu Wang Qianjin Liang Kun Li Xiaojiao Hu Yujin Wu Hui Wang Zhifang Liu Changling Huang | 2017 | The Crop Journal2017,5,5: | 7 |
| 19 | Meta-analysis of the effects of 1-methylcyclopropene(1-MCP)treatment on climacteric fruit ripening显示文摘1-Methylcyclopropene(1-MCP)is an inhibitor of ethylene perception that is widely used to maintain the quality of several climacteric fruits during storage.A large body of literature now exists on the effects of 1-MCP on climacteric fruit ripening for different species and environmental conditions,presenting an opportunity to use meta-analysis to systematically dissect these effects.We classified 44 ripening indicators of climacteric fruits into five categories:physiology and biochemistry,quality,enzyme activity,color,and volatiles.Meta-analysis showed that 1-MCP treatment reduced 20 of the 44 indicators by a minimum of 22%and increased 6 indicators by at least 20%.These effects were associated with positive effects on delaying ripening and maintaining quality.Of the seven moderating variables,species,1-MCP concentration,storage temperature and time had substantial impacts on the responses of fruit to 1-MCP treatment.Fruits from different species varied in their responses to 1-MCP,with the most pronounced responses observed in rosaceous fruits,especially apple,European pear fruits,and tropical fruits.The effect of gaseous 1-MCP was optimal at 1μl/l,with a treatment time of 12–24 h,when the storage temperature was 0℃for temperate fruits or 20℃for tropical fruits,and when the shelf temperature was 20℃,reflecting the majority of experimental approaches.These findings will help improve the efficacy of 1-MCP application during the storage of climacteric fruits,reduce fruit quality losses and increase commercial value. | Jing Zhang Yuanchun Ma Chao Dong Leon A.Terry Christopher B.Watkins Zhifang Yu Zong-Ming(Max)Cheng | 2020 | Horticulture Research2020,7,1: | 7 |
