1Seismic damage of highway bridges during the 2008 Wenchuan earthquake显示文摘Many highway bridges were severely damaged or completely collapsed during the 2008 Wenchuan earthquake.A fi eld investigation was carried out in the strongly affected areas and over 320 bridges were examined.Damage to some representative highway bridges is briefly described and a preliminary analysis of the probable causes of the damage is presented in this paper.The most common damage included shear-flexural failure of the pier columns,expansion joint failure,shear key failure,and girder sliding in the transversal or longitudinal directions due to weak connections between girder and bearings.Lessons learned from this earthquake are described and recommendations related to the design of curved and skewed bridges,design of bearings and devices to prevent girder collapse,and ductility of bridge piers are presented.Suggestions for future seismic design and retrofi tting techniques for bridges in moderate to severe earthquake areas are also proposed.Han Qiang Du Xiuli Liu Jingbo Li Zhongxian Li Liyun Zhao Jianfeng 2009Earthquake Engineering and Engineering Vibration2009,8,2:60

5Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves显示文摘Metamaterials based on effective media can be used to produce a number of unusual physical properties(for example,negative refraction and invisibility cloaking)because they can be tailored with effective medium parameters that do not occur in nature.Recently,the use of coding metamaterials has been suggested for the control of electromagnetic waves through the design of coding sequences using digital elements‘0’and‘1,'which possess opposite phase responses.Here we propose the concept of an anisotropic coding metamaterial in which the coding behaviors in different directions are dependent on the polarization status of the electromagnetic waves.We experimentally demonstrate an ultrathin and flexible polarization-controlled anisotropic coding metasurface that functions in the terahertz regime using specially designed coding elements.By encoding the elements with elaborately designed coding sequences(both 1-bit and 2-bit sequences),the x-and y-polarized waves can be anomalously reflected or independently diffused in three dimensions.The simulated far-field scattering patterns and near-field distributions are presented to illustrate the dual-functional performance of the encoded metasurface,and the results are consistent with the measured results.We further demonstrate the ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions,thus providing powerful control of differently polarized electromagnetic waves.The proposed method enables versatile beam behaviors under orthogonal polarizations using a single metasurface and has the potential for use in the development of interesting terahertz devices.Shuo Liu Tie Jun Cui Quan Xu Di Bao Liangliang Du Xiang Wan Wen Xuan Tang Chunmei Ouyang Xiao Yang Zhou Hao Yuan Hui Feng Ma Wei Xiang Jiang Jiaguang Han Weili Zhang Qiang Cheng 2016Light(Science & Applications)2016,5,1:36
6Radiofrequency ablation or microwave ablation combined with transcatheter arterial chemoembolization in treatment of hepatocellular carcinoma by comparing with radiofrequency ablation alone显示文摘Objective:To compare radiofrequency ablation(RFA) or microwave ablation(MWA) and transcatheter arterial chemoembolization(TACE) with RFA or MWA monotherapy in hepatocellular carcinoma(HCC).Methods:A prospective,randomized,controlled trial was conducted on 94 patients with HCC ≤7 cm at a single tertiary referral center from June 2008 to June 2010 at the Department of Hepatobiliary Surgery,the Second Affiliated Hospital of Southeast University.The patients were randomly assigned into the TACERFA or TACE-MWA(combined treatment group) and the RFA-alone or MWA-alone groups(control group).The primary end point was overall survival.The secondary end point was recurrence-free survival,and the tertiary end point was adverse effects.Results:Until the time of censor,17 patients in the TACE-RFA or TACE-MWA group had died.The median follow-up time of the patients who were still alive for the TACE-RFA or TACE-MWA group was 47.5±11.3 months(range,29 to 62 months).The 1-,3- and 5-year overall survival for the TACE-RFA or TACE-MWA group was 93.6%,68.1% and 61.7%,respectively.Twenty-five patients in the RFA or MWA group had died.The median follow-up time of the patients who were still alive for the RFA or MWA group was 47.0±12.9 months(range,28 to 62 months).The 1-,3- and 5-year overall survival for the RFA or MWA group was 85.1%,59.6% and 44.7%,respectively.The patients in the TACE-RFA or TACE-MWA group had better overall survival than the RFA or MWA group [hazard ratio(HR),0.526;95% confidence interval(95% CI),0.334-0.823;P=0.002],and showed better recurrence-free survival than the RFA or MWA group(HR,0.582;95% CI,0.368-0.895;P=0.008).Conclusions:RFA or MWA combined with TACE in the treatment of HCC ≤7 cm was superior to RFA or MWA alone in improving survival by reducing arterial and portal blood flow due to TACE with iodized oil before RFA.Yongxiang Yi Yufeng Zhang Qiang Wei Liang Zhao Jianbo Han Yan Song Ying Ding Guilan Lu Junmao Liu Huaiying Ding Feng Dai Xiaojun Tang 2014Chinese Journal of Cancer Research2014,26,1:29

8The influence of steel slag on the hydration of cement during the hydration process of complex binder显示文摘The influence of steel slag,a by-product from the processing of iron to steel,on the hydration of cement during the hydration process of complex binder was studied by calorimetry,X-ray diffraction analysis,and Ca(OH)2 content determination.The results show that steel slag and cement affect each other’s hydration by changing the hydration environment.Steel slag does not react with the hydration products of cement.The dormant period of cement-steel slag complex binder during the hydration is longer than that of cement.The more the adding amount of steel slag is,the longer the dormant period of complex binder will be.The steel slag decreases the early hydration rate of cement.This phenomenon is more obvious with the increment of steel slag addition.However,the steel slag can promote the hydration degree of cement at later ages and the promoting effect becomes more obvious with the increment of steel slag addition and the hydration ages.WANG Qiang YAN PeiYu HAN Song 2011Science China(Technological Sciences)2011,54,2:27
9Late Miocene Red River submarine fan,northwestern South China Sea显示文摘A huge submarine fan is discovered through the research of the seismic and borehole data in the binding site of Yinggehai basin and Qiongdongnan basin in northwestern South China Sea.The fan,mainly formed during Late Miocene (Huangliu period) has an area over 10000 km 2 and maximum thickness of over 2000 m.It is characterized by a wedge-shaped oblique progradation configuration on the dip profile and a hummocky bidirectional progradation configuration on the strike profile.The core and Logging data from the well YC35-1-2 located in the front side of the fan indicate that sandy gravity flow deposits are predominant in lower Huangliu Formation and change to interbeds of sand and mud in upper Huangliu Formation.The fan is interpreted as a sand/mud-rich submarine fan in combination with the bathyal geological background of Huangliu period.A preliminary analysis of provenance indicates that neither the Guiren Uplift in the west nor the Hainan Uplift in the north can serve as the major provenance for the submarine fan.The provenance is considered to be from the Red River,based on the sedimentary facies study of the Huangliu Formation in Yinggehai basin.The fan is thus named as 'Red River submarine fan'.The Red River depositional system consists of the Red River submarine fan,the Red River delta,and associated submarine canyons.The discovery of the Red River submarine fan provides important information for the research of the uplift of Tibetan Plateau and the evolvement of Red River Fault Zone.Furthermore,it also points out a new direction for the deepwater hydrocarbon exploration in the northern South China Sea.WANG YingMin XU Qiang LI Dong HAN JianHui LU Ming WANG YongFeng LI WeiGuo WANG HaiRong 2011Chinese Science Bulletin2011,56,14:28

14The role of the HIF-1α/ALYREF/PKM2 axis in glycolysis and tumorigenesis of bladder cancer显示文摘Background:As a rate-limiting enzyme of glycolysis,pyruvate kinase muscle isozyme M2(PKM2)participates in tumor metabolism and growth.The regulatory network of PKM2 in cancer is complex and has not been fully studied in bladder cancer.The 5-methylcytidine(m5C)modification in PKM2 mRNA might participate in the pathogenesis of bladder cancer and need to be further clarified.This study aimed to investigate the biological function and regulatory mechanism of PKM2 in bladder cancer.Methods:The expression of PKM2 and Aly/REF export factor(ALYREF)was measured by Western blotting,qRT-PCR,and immunohistochemistry.The bioprocesses of bladder cancer cells were demonstrated by a series of experiments in vitro and in vivo.RNA immunoprecipitation,RNA-sequencing,and dualluciferase reporter assays were conducted to explore the potential regulatory mechanisms of PKM2 in bladder cancer.Results:In bladder cancer,we first demonstrated that ALYREF stabilized PKM2 mRNA and bound to its m5C sites in 3′-untranslated regions.Overexpression of ALYREF promoted bladder cancer cell proliferation by PKM2-mediated glycolysis.Furthermore,high expression of PKM2 and ALYREF predicted poor survival in bladder cancer patients.Finally,we found that hypoxia-inducible factor-1alpha(HIF-1α)indirectly up-regulated the expression of PKM2 by activating ALYREF in addition to activating its transcription directly.Conclusions:The m5C modification in PKM2 mRNA in the HIF-1α/ALYREF/PKM2 axis may promote the glucose metabolism of bladder cancer,providing a new promising therapeutic target for bladder cancer.Jing-Zi Wang Wei Zhu Jie Han Xiao Yang Rui Zhou Hong-Cheng Lu Hao Yu Wen-Bo Yuan Peng-Chao Li Jun Tao Qiang Lu Ji-Fu Wei Haiwei Yang 2021Cancer Communications2021,41,7:17

16Attribution of PM_(2.5) exposure in Beijing-Tianjin-Hebei region to emissions:implication to control strategies显示文摘The Beijing-Tianjin-Hebei(BTH) region is one of the most heavily polluted regions in China,with both high PM_(2.5) concentrations and a high population density.A quantitative source-receptor relationship can provide valuable insights that can inform effective emission control strategies.Both source apportionment(SA) and source sensitivity(SS) can provide such information from different perspectives.In this study,both methods are applied in northern China to identify the most significant emission categories and source regions for PM_(2.5) exposure in BTH in 2013.Despite their differences,both models show similar distribution patterns for population and simulated PM_(2.5) concentrations,resulting in overall high PM_(2.5) exposure values(approximately 110 μg/m~) and particularly high exposure values during the winter(approximately 200 μ/m~).Both methods show that local emissions play a dominant role(70%),with some contribution from surrounding provinces(e.g.,Shandong) via regional transport.The two methods also agree on the priority of local emission controls:both identify industrial,residential,and agricultural emissions as the top three categories that should be controlled locally.In addition,the effect of controlling agricultural ammonia emissions is approximately doubled when the co-benefits of reducing nitrate are considered.The synthesis of SA and SS for addressing specific categories of emissions provides a quantitative basis for the development of emission control strategies and policies for controlling PM_(2.5)in China.Xin Li Qiang Zhang Yang Zhang Lin Zhang Yuxuan Wang Qianqian Zhang Meng Li Yixuan Zheng Guannan Geng Timothy J.Wallington Weijian Han Wei Shen Kebin He 2017Science Bulletin2017,62,13:15
17Laparoscopic cystogastrostomy for the treatment of pancreatic pseudocysts: A case report显示文摘Pancreatic pseudocysts(PPs) are collections o pancreatic secretions that are lined by fibrous tissue and may contain necrotic debris or blood. The interventions including percutaneous, endoscopic o surgical approaches are based on the size, location symptoms and complications of a pseudocyst With the availability of advanced imaging system and cameras, better hemostatic equipments and excellent laparoscopic techniques, most pseudocyst can be found and managed by laparoscopy. We describe a case of a 30-year-old male patient with a pancreatic pseudocyst amenable to laparoscopi cystogastrostomy. An incision was made through the anterior gastric wall to expose the posterior gastri wall in close contact with the pseudocyst using an ultrasonically activated scalpel. Then, another incision was made for cystogastrostomy to obtain complete and unobstructed drainage. The patient recovered well after operation and was symptom-free during a 6-mo follow-up, suggesting that laparoscopi cystogastrostomy is a safe and effective alternative to open cystogastrostomy for minimally invasive management of PPs.Qin-song Sheng Da-Zhi Chen Ren Lang Zhong-Kui Jin Dong-Dong Han Li-Xin Li Yong-Jiu Yang Ping Li Fei Pan Dong Zhang Zhao-Wei Qu Qiang He 2008World Journal of Gastroenterology2008,14,30:15
18Climate as the dominant control on C_3 and C_4 plant abundance in the Loess Plateau: Organic carbon isotope evidence from the last glacial-interglacial loess-soil sequences显示文摘Abundance of C3 and C4 photosynthesis plants can be inferred relatively from stable carbon isotopic composi-tion of organic matter in soils. The samples from five sequences of the last glacial-interglacial loess-soil in the Chinese Loess Plateau have been measured for organic carbon isotopic ratios (d 13Corg). The organic carbon isotope data show that relative abundance (or biomass) of C4 plants was increased ca. 40% for each sampling site from the last glacial maximum (LGM) to Holocene optimum, and increased southeastward on the Loess Plateau during both periods of LGM and Holocene. Statistic analyses on the steady maximum d 13Corg values of Holocene soils and modern climatic data from the Loess Plateau and Inner Mongolia indicate that the C4 plant abundance increases with increasing temperature and decreasing precipitation. The C4 plant abundance is related much closer with mean April tem-perature and precipitation than annual. These results lead us to deduce following conclusions. First, temperature is the major factor for control on variations in C4 plant abundance in the Loess Plateau from the last glacial to interglacial. In the absence of favorable temperature condition, both of low moisture and low atmospheric CO2 concentration are insufficient to drive an expansion of the C4 plants in the plateau. Second, d 13Corg in the loess-paleosol sequences, as a proxy of the relative abundance of C4 plants in the Loess Plateau, could not be used as an indicator of changes in the summer monsoon intensity unless the tem-perature had changed without great amplitude. Since all C4 plants are grasses, finally, the increase of the C4 plants supports that forest has not been dominant in the ecosystem on the Loess Plateau during Holocene although precipitation and atmospheric CO2 were largely increased relative to those during LGM.GU Zhaoyan, LIU Qiang, XU Bing, HAN Jiamao, YANG Shiling, DING Zhongli & LIU Tungsheng Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing 100029, China Correspondence should be addressed to Gu Zhaoyan (e-mail: zgu@ 95777.com) 2003Chinese Science Bulletin2003,48,12:14
19Development and high-throughput genotyping of substitution lines carting the chromosome segments of indica 9311 in the background of japonica Nipponbare显示文摘Chromosome segment substitution lines(CSSLs) are useful for the precise mapping of quantitative trait loci(QTLs) and dissection of the genetic basis of complex traits.In this study,two whole-genome sequenced rice cultivars,the japonica Nipponbare and indica 9311 were used as recipient and donor,respectively.A population with 57 CSSLs was developed after crossing and back-crossing assisted by molecular markers, and genotypes were identified using a high-throughput resequencing strategy.Detailed graphical genotypes of 38 lines were constructed based on resequencing data.These CSSLs had a total of 95 substituted segments derived from indica 9311,with an average of about 2.5 segments per CSSL and eight segments per chromosome,and covered about 87.4%of the rice whole genome.A multiple linear regression QTL analysis mapped four QTLs for 1000-grain weight.The largest-effect QTL was located in a region on chromosome 5 that contained a cloned major QTL GW5/qSW5 for grain size in rice.These CSSLs with a background of Nipponbare may provide powerful tools for futureHua Zhang Qiang Zhao Zhi-Zhong Sun Chang-Quan Zhang Qi Feng Shu-Zhu Tang Guo-Hua Liang Ming-Hong Gu Bin Han Qiao-Quan Liu 2011Journal of Genetics and Genomics2011,38,12:13
20CCL5 deficiency promotes liver repair by improving inflammation resolution and liver regeneration through M2 macrophage polarization显示文摘Despite the diverse etiologies of drug-induced liver injury(DILI),innate immunity activation is a common feature involved in DILI progression.However,the involvement of innate immunity regulation in inflammation resolution and liver regeneration in DILI remains obscure.Herein,we identified the chemokine CCL5 as a central mediator of innate immunity regulation in the pathogenesis of DILI.First,we showed that serum and hepatic CCL5 levels are elevated in both DILI patients and an APAP-induced liver injury(AILI)mouse model.Interestingly,both nonparenchymal cells and stressed hepatocytes are cell sources of CCL5 induction in response to liver injury.Functional experiments showed that CCL5 deficiency has no effect on the early phase of AILI but promotes liver repair in the late phase mainly by promoting inflammation resolution and liver regeneration,which are associated with an increased number of hepatic M2 macrophages.Mechanistically,CCL5 can directly activate M1 polarization and impede M2 polarization through the CCR1-and CCR5-mediated activation of the MAPK and NF-κB pathways.We then showed that CCL5 inhibition mediated by either a CCL5-neutralizing antibody or the antagonist Met-CCL5 can greatly alleviate liver injury and improve survival in an AILI mouse model.Our data demonstrate CCL5 induction during DILI,identify CCL5 as a novel innate immunity regulator in macrophage polarization,and suggest that CCL5 blockage is a promising therapeutic strategy for the treatment of DILI.Meng Li Xuehua Sun Jie Zhao Lei Xia Jichang Li Min Xu Bingrui Wang Han Guo Chang Yu Yueqiu Gao Hailong Wu Xiaoni Kong Qiang Xia 2020Cellular & Molecular Immunology2020,17,7:13
