| 3 | Cardiotoxicity of 5-fluorouracil and capecitabine in Chinese patients: a prospective study显示文摘Background:5-Fluorouracil(5-FU)and capecitabine-associated cardiotoxicity ranging from asymptomatic electro-cardiography(ECG)abnormalities to severe myocardial infarction has been reported in a number of studies,but such cardiotoxicity in Chinese patients with malignant diseases has not been investigated to date.In the present study,we aimed to prospectively evaluate the incidence rates and clinical manifestations of 5-FU-and capecitabine-associated cardiotoxicity in cancer patients recruited from multiple centers in China.Methods:Among the 527 patients who completed the study,196 received 5-FU-based chemotherapy and 331 received capecitabine-based chemotherapy as either first-line or adjuvant therapy.Adverse events were reported during the treatment and up to 28 days of follow-up.Outcome measures included ECG,myocardial enzymes,cardiac troponin,brain natriuretic peptide and echocardiography.Univariate analysis and logistic regression were performed for subgroup analysis and identification of significant independent variables that are associated with cardiotoxicity of both agents.Results:In total,161 of 527 patients(30.6%)experienced cardiotoxicity.The incidence rate of cardiotoxicity was 33.8%(112/331)in the capecitabine group,which was significantly higher than the rate of 25%(49/196)in the 5-FU group(P=0.0042).110/527 patients(20.9%)suffered arrhythmia,105/527(19.9%)developed ischemic changes,while only 20/527 patients(3.8%)presented heart failure and 6/527 patients(1.1%)had myocardial infarction.Pre-existing cardiac disease,hypertension,capecitabine-based chemotherapy and duration of treatment were identified as sig-nificant risk factors associated with cardiotoxicity.The odds ratio were 15.7(prior history of cardiac disease versus no history),1.86(capecitabine versus 5-FU),1.06(5-8 versus 1-4 chemotherapy cycles)and 1.58(hypertension versus no hypertension),respectively.Conclusions:Cardiotoxicity induced by fluoropyrimidines in the Chinese population may be underestimated in clini-cal practice.Close monitoring of patients is recommended,especially for those patients at high risk for cardiotoxicity.Possible risk factors are duration of treatment,capecitabine-based chemotherapy,pre-existing cardiac diseases and hypertension.Trial registration This study was initiated on January 22,2014 and has been retrospectively registered with the registra-tion number ChiCTR1800015434 . | Jianjun Peng Chao Dong Chang Wang Weihua Li Hao Yu Min Zhang Qun Zhao Bo Zhu Jun Zhang Wenliang Li Fenghua Wang Qiong Wu Wenhao Zhou Ying Yuan Meng Qiu Gong Chen | 2018 | Cancer Communications2018，38，1： | 23 |
| 4 | Soil pH impact on microbial tetraether lipids and terrestrial input index (BIT) in China显示文摘The distributions of microbial tetraether lipids i.e. glycerol dialkyl glycerol tetraethers (GDGTs) were investigated in a variety of Chinese soils featured by a wide range of pH values in different climate zones. The bacterial branched GDGTs and archaeal isoprenoid GDGTs were found to be widely distributed in Chinese soils and their relative abundance was controlled primarily by soil pH. The bacterial bGDGTs usually dominate over archaeal iGDGTs in abundance when the soil pH is below 8.0. However archaeal iGDGTs become dominant and the abundance of halophilic archaea characterized by GDGT V without cyclopentyl ring increases dramatically in the alkaline soil with pH greater than 8.0. The relative abundance of archaeal iGDGTs to bacterial bGDGTs was defined here as RAI index. The RAI index decreases with elevated soil pH and a linear correlation is found between them indicating that the relative abundance of archaeal iGDGTs to bacterial bGDGTs increases with increased pH. The RAI index thus could be a novel proxy of the pH values of paleosol. The terrestrial input index BIT (Branched and Isoprenoid Tetraethers Index) decreases with increased soil pH suggesting that soil pH should be taken into consideration when the terrestrial contribution to marine sediments is estimated by BIT index. Moreover the TEX86 index cannot be used to reconstruct sea surface temperature in the sediments featured by a large terrestrial input. | YANG Huan DING WeiHua WANG JinXiang JIN ChengSheng HE GangQiang QIN YangMin XIE ShuCheng | 2012 | Science China Earth Sciences2012，55，2： | 19 |

| 7 | Environmentally Friendly and Multifunctional Shaddock Peel-Based Carbon Aerogel for Thermal-Insulation and Microwave Absorption显示文摘Eco-friendly electromagnetic wave absorbing materials with excellent thermal infrared stealth property,heat-insulating ability and compression resistance are highly attractive in practical applications.Meeting the aforesaid requirements simultaneously is a formidable challenge.Herein,ultra-light carbon aerogels were fabricated via fresh shaddock peel by facile freeze-drying method and calcination process,forming porous network architecture.With the heating platform temperature of 70℃,the upper surface temperatures of the as-prepared carbon aerogel present a slow upward trend.The color of the sample surface in thermal infrared images is similar to that of the surroundings.With the maximum compressive stress of 2.435 kPa,the carbon aerogels can provide favorable endurance.The shaddock peel-based carbon aerogels possess the minimum reflection loss value(RLmin)of−29.50 dB in X band.Meanwhile,the effective absorption bandwidth covers 5.80 GHz at a relatively thin thickness of only 1.7 mm.With the detection theta of 0°,the maximum radar cross-sectional(RCS)reduction values of 16.28 dB m^(2) can be achieved.Theoretical simulations of RCS have aroused extensive interest owing to their ingenious design and time-saving feature.This work paves the way for preparing multi-functional microwave absorbers derived from biomass raw materials under the guidance of RCS simulations. | Weihua Gu Jiaqi Sheng Qianqian Huang Gehuan Wang Jiabin Chen Guangbin Ji | 2021 | Nano-Micro Letters2021，13，7： | 11 |
| 8 | Spatial and temporal dynamics of phytoplankton and bacterioplankton biomass in Sanya Bay, northern South China Sea显示文摘The composition of phytoplankton and the dynamics of phytoplankton and bacterioplankton biomass (PB and BB, respectively) of Sanya Bay, South China Sea, were determined. A total of 168 species (67 genera) phytoplankton were identified, including Bacillariophyta (diatom, 128 species), Pyrrophyta (35 species), Cyanophyta (3 species), and Chrysophyta (2 species). Annual average abundance of phytoplankton was 1.2 × 107 cells/m3, with the highest abundance in autumn, and the lowest in summer. Annual average diversity index (H ) and evenness (J) values were 3.96 and 0.70, respectively. Average chlorophyll-a was 2.5 mg/m3, and the average PB was 124 mg C/m3, with the highest value in autumn. Surface PB was higher than the bottom, except for summer. Annual mean bacterioplankton abundance and BB were 6.9 × 1011 cells/m3 and 13.8 mg C/m3, respectively. The highest BB was found in summer, followed by winter, spring, and autumn. Surface BB was higher than bottom all year round. The spatial distribution patterns of PB and BB were very similar with the highest biomass in the estuary, and decreased seaward, primarily due to the terrestrial input from the Sanya River and influx of oceanic water. The main factor influencing PB and BB was dissolved inorganic nitrogen (DIN). Other factors such as temperature, which is above 22°C throughout the year, had a negligible impact. The correlation between BB and PB was significant (P < 0.01). The annual average ratio of BB/PB was 0.12 (0.06-0.15). Phytoplankton primary production was one of the most important factors in controlling the distribution of bacterioplankton. | ZHOU Weihua | 2009 | Journal of Environmental Sciences2009，21，5： | 11 |
| 9 | Characteristics and sedimentary processes of lamina-controlled sand-particle imbricate structure in deposits on Lingshan Island, Qingdao, China显示文摘Imbricate structure is a common sedimentary structure and is well developed in sandy sediments.Here,we report a laminacontrolled fine-sand-particle imbricate structure in a set of very fine grained sedimentary rocks(fine sandstone,siltstone,and mudstone)at the Dockyard and Qianceng Cliff areas of Lingshan Island,Qingdao,Shandong,China.Sets of up to 300 laminae are found in stratigraphic profiles in these areas.The laminae are generally less than 1 mm thick,with most being 0.3–0.4 mm thick and the thinnest being<0.1 mm.The dip angle of the imbricate structure varies widely,between 0°and 90°,with an average dip angle of about 40°–50°,which is higher than that of imbricate riverbed gravels(about 34°).The dip angle is a function of the shape and sorting of the particles,as well as the hydrodynamic conditions under which these fine-grained sediments were deposited.Several profiles show well-developed multiscale,soft-sediment deformation structures.Flute casts,load casts,and groove casts are also common.Fragments of carbon remains occur widely and commonly constitute stringers several millimeters thick and up to 10 cm long,together with fine clasts.Vitrain lenticles are also common.Based on the imbricate structure of the Lingshan Island deposits,it is shown that in addition to paleocurrent analysis,the imbricate structure can be used to infer information about fluid properties,transport characteristics,and sedimentary processes of the depositional environment.A near-bottom underflow,either of authigenic origin or derived from cold river water in winter in a delta interdistributary bay or delta-front environment,is inferred to have provided the hydrodynamic setting in which this imbricate structure formed.The imbricate structure,together with other sedimentary structures and features,shows that the sedimentary rocks on Lingshan Island were deposited in an inland,shallow-water environment,such as a delta,and not in a deep-water or submarine continental-slope environment. | SHAO ZhuFu ZHONG JianHua LI Yong MAO Cui LIU ShengXin NI LiangTian TIAN Yuan CUI XinYing LIU YunTian WANG XiaoNan LI WeiHua LIN GangShan | 2014 | Science China Earth Sciences2014，57，5： | 11 |
| 10 | Experimental comparison between aircraft fuel tank inerting processes using NEA and MIG显示文摘Fuel tank inerting technologies are able to reduce the fire risk by injection of inert gas into the ullage or fuel, the former called ullage washing and the latter fuel scrubbing. The Green On-Board Inert Gas Generation System(GOBIGGS) is a novel technology based on flameless catalytic combustion, and owning to its simple structure and high inerting efficiency, it has received a lot of attentions. The inert gas in the GOBIGGS is mainly comprised of CO_2, N_2, and O_2(hereinafter, Mixed Inert Gas(MIG)), while that in the On-Board Inert Gas Generation System(OBIGGS), which is one of the most widely used fuel tank inerting technologies, is NitrogenEnriched Air(NEA). The solubility of CO_2 is nearly 20 times higher than that of N_2 in jet fuels,so the inerting capability and performance are definitely disparate if the inert gas is selected as NEA or MIG. An inerting test bench was constructed to compare the inerting capabilities between NEA and MIG. Experimental results reveal that, if ullage washing is adopted, the variations of oxygen concentrations on the ullage and in the fuel are nearly identical no matter the inert gas is NEA or MIG. However, the ullage and dissolved oxygen concentrations of MIG scrubbing are always higher than those of NEA scrubbing. | Lei SHAO Weihua LIU Chaoyue LI Shiyu FENG Chenchen WANG Jun PAN | 2018 | Chinese Journal of Aeronautics2018，31，7： | 11 |
| 11 | Enhanced efficiency of cadmium removal by Boehmeria nivea(L.) Gaud. in the presence of exogenous citric and oxalic acids显示文摘Boehmeria nivea(L.)Gaud.is a potential candidate for the remediation of Cd contaminated sites.The present investigation aims to explore Cd tolerance threshold and to quickly identify the role of exogenous organic acids in Cd uptake and abiotic metal stress damage.Elevated Cd levels(0–10 mg/L)resulted in an obvious rise in Cd accumulation,ranging from268.0 to 374.4 in root and 25.2 to 41.2 mg/kg dry weight in shoot,respectively.Citric acid at1.5 mmol/L significantly facilitated Cd uptake by 26.7%in root and by 1-fold in shoot,respectively.Cd translocation efficiency from root to shoot was improved by a maximum of66.4%under 3 mmol/L of oxalic acid.Citric acid exhibited more prominent mitigating effect than oxalic acid due to its stronger ligand affinity for chelating with metal and avoiding the toxicity injury of free Cd ions more efficiently.The present work provides a potential strategy for efficient Cd remediation with B.nivea. | Huaying Li Yunguo Liu Guangming Zeng Lu Zhou Xin Wang Yaqin Wang Chunlin Wang Xinjiang Hu Weihua Xu | 2014 | Journal of Environmental Sciences2014，26，12： | 10 |
| 12 | Parameter selection of support vector regression based on hybrid optimization algorithm and its application显示文摘Choosing optimal parameters for support vector regression (SVR) is an important step in SVR design, which strongly affects the performance of SVR. In this paper, based on the analysis of influence of SVR parameters on generalization error, a new approach with two steps is proposed for selecting SVR parameters . First the kernel function and SVM parameters are optimized roughly through genetic algorithm, then the kernel parameter is finely adjusted by local linear search. This approach has been successfully applied to the prediction model of the sulfur content in hot metal. The experiment results show that the proposed approach can yield better generalization performance of SVR than other methods. | Xin WANG Chunhua YANG Bin QIN Weihua GUI | 2005 | 控制理论与应用(英文版)2005，3，4： | 9 |
| 13 | Application of profile likelihood function to the uncertainty analysis of hydrometeorological extreme inference显示文摘Profile likelihood function is introduced to analyze the uncertainty of hydrometeorological extreme inference and the theory of estimating confidence intervals of the key parameters and quantiles of extreme value distribution by profile likelihood function is described.GEV(generalized extreme value)distribution and GP(generalized Pareto)distribution are used respectively to fit the annual maximum daily flood discharge sample of the Yichang station in the Yangtze River and the daily rainfall sample in10 big cities including Guangzhou.The parameters of the models are estimated by maximum likelihood method and the fitting results are tested by probability plot,quantile plot,return level plot and density plot.The return levels and confidence intervals of flood and rainstorm in different return periods are calculated by profile likelihood function.The results show that the asymmetry of the profile likelihood function curve increases with the return period,which can reflect the effect of the length of sample series and return periods on confidence interval.As an effective tool for estimating confidence interval of the key parameters and quantiles of extreme value distribution,profile likelihood function can lead to a more accurate result and help to analyze the uncertainty of extreme values of hydrometeorology. | LU Fan WANG Hao YAN DengHua ZHANG DongDong XIAO WeiHua | 2013 | Science China(Technological Sciences)2013，56，12： | 8 |
| 14 | Chronic intermittent hypoxia accelerates liver fibrosis in rats with combined hypoxia and nonalcoholic steatohepatitis via angiogenesis rather than endoplasmic reticulum stress显示文摘In the present study,we aimed to investigate the role of endoplasmic reticulum stress(ERS)and its related inflammation and angiogenesis in liver fibrosis in a rat model of combined hypoxia and nonalcoholic steatohepatitis(NASH)and to confirm whether the intervention of hypoxia-inducible factor 1α(HIF1α)can improve fibrosis.Liver histological changes and biochemical indices,HIF1α,inflammatory factors,ERS-related parameters(GRP78,CHOP,caspase-3,and caspase-12),and angiogenesis indices(VEGFA,VEGFR2,and CD34)were evaluated.Compared with the control rats,the liver tissue of rats with hypoxia and NASH had obvious NASH characteristics and hepatic fibrosis was significantly aggravated,including bridging fibrosis in some rats.The mRNA expression levels of HIF1α,VEGFA,and VEGFR2 and total immunohistochemical staining scores of VEGFR2 and CD34 were significantly increased.In addition,HIF1α silencing significantly decreased HIF1α,biochemical indices(ALT,AST,and TG),inflammatory factors(TNFα,IL6,and IL1β),and angiogenesis indices(CD34 and VEGFR2),consequently,improved the hepatic fibrosis score in the rat model of combined hypoxia and NASH.Taken together,chronic intermittent hypoxia accelerates liver fibrosis in rats with combined hypoxia and NASH via angiogenesis rather than ERS and HIF1α intervention can improve liver fibrosis,angiogenesis,inflammatory factors,and biochemical indices.Therefore,HIF1α is a key regulatory factor of liver fibrosis in rats with combined hypoxia and NASH. | Wei Wu Weiping Li Jiaojiao Wei Chunsheng Wang Yunliang Yao Weihua Zhu Weimei He Weimei Zhou Jiang Liu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，2： | 8 |
| 15 | Effects of tube system and data correction for fluctuating pressure test in wind tunnel显示文摘The accuracy of fluctuating pressure test in wind tunnel is affected by the tube system. By employing contradistinctive experimental method, systematic study was conducted to investigate the effects of the tube system on fluctuating pressure. The analyzed tube system parameters include tube length, inside diameter, curvature, deflection angle, thickness, material, restrictor length,restrictor inside diameter, and restrictor place. It is found that all the tube system parameters mentioned above except tube curvature have non-negligible effects on fluctuating pressure. Based on the research results, test methods were presented for the fluctuating pressure measurement in low-speed wind tunnel, which can obviously improve the data accuracy but not lose test efficiency. The effectiveness of the method is verified by the wind tunnel test. | Xue WANG Xunnian WANG Xiaobo REN Xiwei YIN Weihua WANG | 2018 | Chinese Journal of Aeronautics2018，31，4： | 7 |
| 16 | Integrated simulation and assessment of water quantity and quality for a river under changing environmental conditions显示文摘The water cycle and water resources within river basins under changing environmental conditions undergo profound changes, which have significant effects on the water environment of the river. Owing to the water resources demanded for economic and social development, water quantity and quality are becoming the core constraints of water resources development and utilization. In this paper, the dual attributes of water resources, progress into research regarding water quantity and quality joint assessment and simulation and the shortcomings associated with these techniques are summarized and described with respect to water quantity and quality. The results indicated that under the current environmental conditions, the method used for traditional water quality assessment of single water bodies cannot meet the requirements for water resources management. Moreover, a coupled hydrodynamic and water quality numerical model for river networks and lakes that applies to the river water environment system was developed for the river network flow and pollutant migration and transformation process and validated. This validation revealed that the error between the simulated values calculated by the model and the monitored values was small, meeting the application requirements and realizing the integrated and dynamic simulation of water quantity and quality of the river water environmental system. On this basis, the integrated simulation model was applied to the Luanhe River Basin. | WANG JianHua XIAO WeiHua WANG Hao CHAI ZengKai NIU CunWen LI Wei | 2013 | Chinese Science Bulletin2013，58，27： | 7 |
| 17 | Physiological responses and detoxific mechanisms to Pb,Zn,Cu and Cd in young seedlings of Paulownia fortunei显示文摘Paulownia fortunei has been successfully used in the phytoremediation of many Pb/Zn mine tailings.However,seed germination and young seedlings of P.fortunei rarely occurred in these mine tailings.The physiological responses and detoxific mechanisms of P.fortunei young seedling to Pb,Zn,Cu and Cd stress were investigated.The germinated rate,shoot length,chlorophyll and carotenoid contents in leaves of young seedlings had a great reduction under Zn and Cu treatments,but had little decrease under Pb and Cd treatments.The production rate of O2.,H2O2 and malondialdehyde (MDA) contents significantly increased in response to added Zn and Cu indicating great oxidative stress for young seedlings,but they had no significant change to added Pb and Cd.Young seedlings had effective detoxific mechanism to Pb and Cd,as antioxidant enzymes activities,phytochelatins (PCs-SH) and proline contents increased with increasing rates of added Pb and Cd.However,young seedlings had un-effective detoxific mechanisms to Zn and Cu stress.Results revealed the heavy metals (such as Cu) that present at low concentrations in mine tailings may be major constraint for the survival of young seedlings. | Jiang Wang Weihua Li Chongbang Zhang Shisheng Ke | 2010 | Journal of Environmental Sciences2010，22，12： | 7 |
| 18 | Synergistic effect of ozonation and ionizing radiation for PVA decomposition显示文摘Ozonation and ionizing radiation are both advanced oxidation processes(AOPs) without chemical addition and secondary pollution. Also, the two processes' efficiency is determined by different p H conditions, which creates more possibilities for their combination. Importantly,the combined process of ozonation and ionizing radiation could be suitable for treating wastewaters with extreme p H values, i.e., textile wastewater. To find synergistic effects, the combined process of ozonation and ionizing radiation mineralization was investigated for degradation of polyvinyl alcohol(PVA) at different p H levels. A synergistic effect was found at initial p H in the range 3.0–9.4. When the initial p H was 3.0, the combined process of ozonation and ionizing radiation gave a PVA mineralization degree of 17%. This was 2.7 times the sum achieved by the two individual processes, and factors of 2.1 and 1.7 were achieved at initial p H of7.0 and 9.4, respectively. The combined process of ozonation and ionizing radiation was demonstrated to be a feasible strategy for treatment of PVA-containing wastewater. | Weihua Sun Lujun Chen Yongming Zhang Jianlong Wang | 2015 | Journal of Environmental Sciences2015，27，8： | 7 |
| 19 | High loading FeS2 nanoparticles anchored on biomass-derived carbon tube as low cost and long cycle anode for sodium-ion batteries显示文摘In recent years, the sodium storage mechanism and performance optimization of FeS2 have been studied intensively. However, before the commercial application of FeS2, preconditions of low-cost, simple craft and scale production of nanoscale FeS2 are also essential. Based on above challenges, mesh-like FeS2/carbon tube/FeS2 composites are prepared simply from green, low-cost and renewable natural herb in this work. With the assistance of protogenetic interconnected carbon tube network(only 5.3 wt%), FeS2/carbon tube/FeS2 composites show high capacity(542.2 mA h g^-1), good stability(< 0.005% per cycle over 1000 cycles), and excellent rate performance(426.2 mA h g^-1 at 2 A g^-1).The outstanding electrochemical performance of FeS2/carbon tube/FeS2 composites may be attributed to the unique interconnected reticular structure, meaning that FeS2 nanoparticles are effectively immobilized by carbon tube network via physical encapsulation and chemical bonding.More importantly, this work may provide green and low cost preparation method for specially structured metal sulfides/carbon composites,which promotes their commercial utilization in environmentally friendly energy storage system. | Kongyao Chen Gaojie Li Yanjie Wang Weihua Chen Liwei Mi | 2020 | Green Energy & Environment2020，5，1： | 7 |
| 20 | The point defect and electronic structure of K doped LaCo_(0.9)Fe_(0.1)O_(3)perovskite with enhanced microwave absorbing ability显示文摘ABO_(3)perovskites,owning unique properties,have great research prospect in electromagnetic wave absorption field.Normally,doping can significantly regulate the dielectric loss,whereas the magnetic loss can be ignored.In this work,the crystal structure and electromagnetic properties can be regulated systematically by the K,Fe co-doping for LaCoO_(3)perovskites(LKCFO)under the condition of fixed F content.In addition,the obtained samples show the obvious interfacial polarization effect on accounting to the small size effect,which is conducive to the effective microwave absorption.By analyzing the evolution of the positron annihilation lifetime and the first-principles calculation of the oxygen density of states for the series of LKCFO perovskites,it is found that the charge transport characteristics will be controlled by the point defect generated by allelic doping.The point defect content decreases and then increases as the doping level rises.The prepared perovskite exhibits the lowest defect density and the largest dielectric loss capability,which indicates that the lower point defects promote electron migration and thus enhance the dielectric loss;thus,the electromagnetic wave absorption bandwidth up to 6.2 GHz is reached.In contrast,both insufficient and excessive K doping are detrimental to the enhancement of microwave absorption.Especially,the practical application value was investigated using Computer Simulation Technology(CST)simulations.The LKCFO-2 exhibits the smallest RCS value(below-10 dBm^(2))at almost-90°-90°with a thickness of 2 mm,providing an effective method for study excellent microwave absorption and scattering property. | Fan Wang Weihua Gu Jiabin Chen Yue Wu Ming Zhou Shaolong Tang Xingzhong Cao Peng Zhang Guangbin Ji | 2022 | Nano Research2022，15，4： | 7 |
