1Prognostic factors of refractory NSCLC patients receiving anlotinib hydrochloride as the third-or further-line treatment显示文摘Objective:Anlotinib hydrochloride is a multitarget tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor,fibroblast growth factor receptor,platelet-derived growth factor receptor,c-Kit,and c-MET;therefore,it exhibits both antitumor and anti-angiogenetic activities.A phase III trial has shown that anlotinib improved progression-free survival(PFS)and overall survival(OS)in patients with advanced non-small cell lung cancer(NSCLC),who presented with progressive disease or intolerance after standard chemotherapy.This study aimed to analyze the characteristics of patients receiving anlotinib treatment to determine the dominant populations who are fit for the treatment.Methods:Data were collected from March 2015 to January 2017 from a randomized,double-blind,placebo-controlled,multicenter,phase III trial of anlotinib(ALTER0303).A total of 437 patients were enrolled and randomly allocated(2:1)to the anlotinib and placebo groups.Kaplan–Meier analysis and log-rank test were performed to compare PFS and OS.Cox proportional hazards model was adopted for multivariate prognostic analysis.Results:Multivariate analysis indicated that high post-therapeutic peripheral blood granulocyte/lymphocyte ratio and elevated alkaline phosphatase levels were independent risk factors for PFS.Meanwhile,elevated thyroid-stimulating hormone,blood glucose,and triglyceride levels;hypertension;and hand–foot syndrome were independent protective factors of PFS.High posttherapeutic peripheral blood granulocyte/lymphocyte ratio,an Eastern Cooperative Oncology Group(ECOG)score≥2,and the sum of the maximal target lesion length at baseline were independent risk factors of OS,and hypertriglyceridemia was an independent protective factor of OS.Conclusions:This study preliminarily explored the possible factors that affected PFS and OS after anlotinib treatment in patients with advanced refractory NSCLC,and the baseline characteristics of the therapeutically dominant populations were then identified.Jing Wang Yizhuo Zhao Qiming Wang Li Zhang Jianhua Shi Zhehai Wang Ying Cheng Jianxing He Yuankai Shi Hao Yu Yang Zhao Weiqiang Chen Yi Luo Xiuwen Wang Kejun Nan Faguang Jin Jian Dong Baolan Li Zhujun Liu Baohui Han Kai Li 2018Cancer Biology & Medicine2018,15,4:46

3Geological analysis and FT dating of the large-scale right-lateral strike-slip movement of the Red River fault zone显示文摘Tectonically, the large-scale right-lateral strike-slip movement along the Red River fault zone is char-acterized at its late phase with the southeastward extension and deformation of the Northwestern Yunnan normal fault depression on its northern segment, and the dextral shear displacement on its central-southern segment. Research of the relations between stratum deformation and fault movement on the typical fault segments, such as Jianchuan, southeast Midu, Yuanjiang River, Yuanyang, etc. since the Miocene Epoch shows that there are two times dextral faulting dominated by normal shearing occurring along the Red River fault zone since the Miocene Epoch. The fission track dating (abbrevi-ated to FT dating, the same below) is conducted on apatite samples collected from the above fault segments and relating to these movements. Based on the measured single grain’s age and the con-fined track length, we choose the Laslet annealing model to retrieve the thermal history of the samples, and the results show that the fault zone experienced two times obvious shear displacement, one in 5.5 ± 1.5 MaBP and the other in 2.1± 0.8 MaBP. The central-southern segment sees two intensive uplifts of mountain mass in the Yuanjiang River-Yuanyang region at 3.6―3.8 MaBP and 1.6―2.3 MaBP, which correspond to the above-mentioned two dextral normal displacement events since the late Miocene Epoch.XIANG HongFa WAN JingLin HAN ZhuJun GUO ShunMin ZHANG WanXia CHEN LiChun DONG XingQuan 2007Science China Earth Sciences2007,50,3:10
4The Suitability of Using Leaf Area Index to Quantify Soil Loss under Vegetation Cover显示文摘Soil erosion by water under forest cover is a serious problem in southern China.A comparative study was carried out on the use of leaf area index(LAI) and vegetation fractional coverage(VFC) in quantifying soil loss under vegetation cover.Five types of vegetation with varied LAI and VFC under field conditions were exposed to two rainfall rates(40 mm h-1 and 54 mm h-1) using a portable rainfall simulator.Runoff rate,sediment concentration and soil loss rate were measured at relatively runoff stable state.Significant negative exponential relationship(p < 0.05,R2 = 0.83) and linear relationship(p < 0.05,R2 = 0.84) were obtained between LAI and sediment concentration,while no significant relationship existed between VFC and sediment concentration.The mechanism by which vegetation canopy prevents soil loss was by reducing rainfall kinetic energy and sediment concentration.LAI could better quantify such a role than VFC.However,neither LAI nor VFC could explain runoff rate or soil loss rate.Caution must be taken when using LAI to quantify the role of certain vegetation in soil and water conservation.ZHANG Wentai YU Dongsheng SHI Xuezheng WANG Hongjie GU Zhujun ZHANG Xiangyan TAN Manzhi 2011Journal of Mountain Science2011,8,4:7
5Spatial and temporal distribution of Neolithic sites in coastal China:Sea level changes, geomorphic evolution and human adaption显示文摘The East China coastal plain is one of the most important Neolithic culture areas in China, where rich archaeological sites including those producing the earliest domesticated rice are observed. It is also a place where landscape has experienced dramatic evolution during the Holocene when both sea level and climate changed, such that it is an ideal place for studying human-environment interaction. This study investigated over 2000 sites of pre-history and Shang and Zhou Dynasties, with 655 of which being Neolithic ages, by using DEM and GIS methods. The results suggest that the spatial and temporal distribution of Neolithic sites has largely been controlled by landscape evolution(particularly changes in coastal line), which ultimately governed by sea level changes. During early Holocene, Neolithic sites sparsely distributed in the intermountain basins of east Zhejiang Province, far from the influence of ocean. Over the period of 9–7 ka, the coastal plain(including the shelf) was largely submerged,only the feet of low hills to the south and southwest of the study area, and islands protruding the estuary, cradled limited number of settlements with characteristic 'maritime components'. At about 7 ka, sea level rise decelerated prominently, while sediments supply in the drainage remained high value, the combination of which led to land formation and propagation. Vast space during this period facilitated the growth of settlements in both size and number. In the mean time, however, the coastal plain was vulnerable to extreme environmental events such as storms and flooding owning to its geomorphic nature, which exerted great influence on the rise and fall of Neolithic culture.ZHENG HongBo ZHOU YouSheng YANG Qing HU ZhuJun LING GuangJiu ZHANG JuZhong GU ChunGuang WANG YingYing CAO YeTing HUANG XianRong CHENG Yue ZHANG XiaoYu WU WenXiang 2018Science China Earth Sciences2018,61,2:7

8High expression of FABP4 in colorectal cancer and its clinical significance显示文摘Objective:To investigate the relationship between the fatty acid-binding protein 4(FABP4)and colorectal cancer(CRC).Methods:Using an enzyme-linked immunosorbent assay(ELISA),we measured the expression of FABP4 in plasma of50 patients who underwent surgery for CRC from October 2017 to May 2018 and 50 healthy controls.The content of the visceral fat area(VFA)as seen with abdominal computed tomography(CT)scanning was measured by ImageJ software.The expression levels of FABP4,E-cadherin,and Snail proteins in CRC and adjacent tissues were determined by immunohistochemistry.Results:The mean concentration of plasma FABP4 of CRC patients was higher than that of the control group(22.46 vs.9.82 ng/m L;P<0.05).The concentration of plasma FABP4 was related to the tumor,node,metastatis(TNM)stage and lymph node metastasis and was independent of age,body mass index(BMI),tumor size and location,and the degree of differentiation of CRC.The concentration of plasma FABP4 was positively correlated with high VFA and lipoprotein-a(LPA)(P<0.05);but it was not correlated with total cholesterol(TG),total triglyceride(TC),low-density lipoprotein(LDL),high-density lipoprotein(HDL),or apolipoprotein AI(Apo-AI).The expression of FABP4 protein in CRC tissues was positively correlated with the degree of CRC differentiation,tumor stage,and lymph node metastasis.The level of FABP4 protein was negatively correlated with E-cadherin protein(r=-0.3292,P=0.0196)and positively correlated with Snail protein(r=0.5856,P<0.0001).Conclusions:High LPA and VFA were risk factors for increased plasma FABP4 in CRC patients.FABP4 protein was highly expressed in CRC tissues and associated with TNM stage,differentiation,and lymph node metastasis of CRC.The level of FABP4 in CRC tissue was correlated with E-cadherin and Snail expression,suggesting that FABP4 may promote CRC progression related to epithelial-mesenchymal transition(EMT).Yan ZHANG Wenjia ZHANG Min XIA Zhujun XIE Fangmei AN Qiang ZHAN Wenying TIAN Tianyue ZHU 2021Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021,22,2:5
9Defect-rich titanium nitride nanoparticle with high microwaveacoustic conversion efficiency for thermoacoustic imaging-guided deep tumor therapy显示文摘Pulse microwave excite thermoacoustic(TA)shockwave to destroy tumor cells in situ.This has promising applications for precise tumor therapy in deep tissue.Nanoparticle(NP)with high microwave-acoustic conversion is the key to enhance the efficiency of therapy.In this study,we firstly developed defect-rich titanium nitride nanoparticles(TiN NPs)for pulse microwave excited thermoacoustic(MTA)therapy.Due to a large number of local structural defects and charge carriers,TiN NPs exhibit excellent electromagnetic absorption through the dual mechanisms of dielectric loss and resistive loss.With pulsed microwave irradiation,it efficiently converts the microwave energy into shockwave via thermocavitation effect,achieving localized mechanical damage of mitochondria in the tumor cell and yielding a precise antitumor effect.In addition to the therapeutic function,the NP-mediated TA process also generates images that provide valuable information,including tumor size,shape,and location for treatment planning and monitoring.The experimental results showed that the TiN NPs could be efficiently accumulated in the tumor via intravenous infusion.With the deep tissue penetration characteristics of microwave,the proposed TiN-mediated MTA therapy effectively and precisely cures tumors in deep tissue without any detectable side effects.The results indicated that defect-rich TiN NPs are promising candidates for tumor therapy.Zhujun Wu Fanchu Zeng Le Zhang Shuxiang Zhao Linghua Wu Huan Qin Da Xing 2021Nano Research2021,14,8:4
10Bevacizumab promotes active biological behaviors of human umbilical vein endothelial cells by activating TG Fpi pathways via off-VEGF signaling显示文摘Objective:Bevacizumab is a recombinant humanized monoclonal antibody that blocks vascular endothelial growth factor(VEGF)with clear clinical benefits.However,overall survival of some cancer types remains low owing to resistance to bevacizumab therapy.While resistance is commonly ascribed to tumor cell invasion induced by hypoxia-inducible factor(HIF),less attention has been paid to the potential involvement of endothelial cells(ECs)in vasculature activated by anti-angiogenic drugs.Methods:Human umbilical vein ECs(HUVECs),bEnd.3 cells,and mouse retinal microvascular ECs(MRMECs)were treated with bevacizumab under conditions of hypoxia and effects on biological behaviors,such as migration and tube formation,examined.Regulatory effects on TGFpi and CD 105(endoglin)were established via determination o f protein and mRNA levels.We further investigated whether the effects of bevacizumab could be reversed using the receptor tyrosine kinase inhibitor anlotinib.Results:Bevacizumab upregulated TGFpi as well as CD 105,a component o f the TGFP receptor complex and an angiogenesis promoter.Elevated CD 105 induced activation of Sm adl/5,the inflammatory pathway and endothelial-mesenchymal transition.The migration ability of HUVECs was enhanced by bevacizumab under hypoxia.Upregulation o f CD 105 was abrogated by anlotinib,which targets multiple receptor tyrosine kinases including VEGFR2/3,FGFR1-4,PD G FRα/β,C-Kit,and RET.Conclusions:Bevacizumab promotes migration and tube formation of HUVECs via activation of the TGFβi pathway and upregulation of CD105 expression.Anlotinib reverses the effects of bevacizumab by inhibiting the above signals.Xiaoling Zhang Yan Zhang Yanan Jia Tingting Qin Cuicui Zhang Yueya Li Chengmou Huang Zhujun Liu Jing Wang Kai Li 2020Cancer Biology & Medicine2020,17,2:3

19the National Natural Science Foundation of China(41877029,41961130383);Royal SocietyNewton Advanced Fellowship(NAF\R1\191017);Wuhan Science and Technology Bureau(2019020701011469).显示文摘Due to the tremendous diversity of microbial organisms in topsoil,the estimation of saturated richness in a belowground ecosystem is still challenging.Here,we intensively surveyed the 16S rRNA gene in four 1 m2 sampling quadrats in a typical grassland,with 141 biological or technical replicates generating over 11 million sequences per quadrat.Through these massive data sets and using both non-asymptotic extrapolation and non-parametric asymptotic approaches,results revealed that roughly 15919±193,27193±1076 and 56985±2347 prokaryotic species inhabited in 1 m2 topsoil,classifying by DADA2,UPARSE(97%cutoff)and Deblur,respectively,and suggested a huge difference among these clustering tools.Nearly 500000 sequences were required to catch 50%species in 1 m2,while any estimator based on 500000 sequences would still lose about a third of total richness.Insufficient sequencing depth will greatly underestimate both observed and estimated richness.At least~911000,~3461000,and~1878000 sequences were needed for DADA2,UPARSE,and Deblur,respectively,to catch 80%species in 1 m2 topsoil,and the numbers of sequences would be nearly twice to three times on this basis to cover 90%richness.In contrast,α-diversity indexes characterized by higher order of Hill numbers,including Shannon entropy and inverse Simpson index,reached saturation with fewer than 100000 sequences,suggesting sequencing depth could be varied greatly when focusing on exploring differentα-diversity characteristics of a microbial community.Our findings were fundamental for microbial studies that provided benchmarks for the extending surveys in large scales of terrestrial ecosystems.Shuzhen Li Xiongfeng Du Kai Feng Yueni Wu Qing He Zhujun Wang Yangying Liu Danrui Wang Xi Peng Zhaojing Zhang Arthur Escalas Yuanyuan Qu Ye Deng 2022Soil Ecology Letters2022,4,3:1
