| 1 | Source apportionment and secondary organic aerosol estimation of PM_(2.5) in an urban atmosphere in China显示文摘PM2.5 is the key pollutant in atmospheric pollution in China.With new national air quality standards taking effect,PM2.5 has become a major issue for future pollution control.To effectively prevent and control PM2.5,its emission sources must be precisely and thoroughly understood.However,there are few publications reporting comprehensive and systematic results of PM2.5 source apportionment in the country.Based on PM2.5 sampling during 2009 in Shenzhen and follow-up investigation,positive matrix factorization(PMF)analysis has been carried out to understand the major sources and their temporal and spatial variations.The results show that in urban Shenzhen(University Town site),annual mean PM2.5 concentration was 42.2μg m?3,with secondary sulfate,vehicular emission,biomass burning and secondary nitrate as major sources;these contributed30.0%,26.9%,9.8%and 9.3%to total PM2.5,respectively.Other sources included high chloride,heavy oil combustion,sea salt,dust and the metallurgical industry,with contributions between 2%–4%.Spatiotemporal variations of various sources show that vehicular emission was mainly a local source,whereas secondary sulfate and biomass burning were mostly regional.Secondary nitrate had both local and regional sources.Identification of secondary organic aerosol(SOA)has always been difficult in aerosol source apportionment.In this study,the PMF model and organic carbon/elemental carbon(OC/EC)ratio method were combined to estimate SOA in PM2.5.The results show that in urban Shenzhen,annual SOA mass concentration was 7.5μg m?3,accounting for 57%of total organic matter,with precursors emitted from vehicles as the major source.This work can serve as a case study for further in-depth research on PM2.5 pollution and source apportionment in China. | HUANG XiaoFeng YUN Hui GONG ZhaoHeng LI Xiang HE LingYan ZHANG YuanHang HU Min | 2014 | Science China Earth Sciences2014，57，6： | 28 |
| 2 | Toxicities and risk assessment of heavy metals in sediments of Taihu Lake, China, based on sediment quality guidelines显示文摘The occurrence, toxicities, and ecological risks of five heavy metals(Pb, Cu, Cd, Zn and Ni) in the sediment of Taihu Lake were investigated in this study. To evaluate the toxicities caused by the heavy metals, the toxicities induced by organic contaminants and ammonia in the sediments were screened out with activated carbon and zeolite. The toxicities of heavy metals in sediments were tested with benthic invertebrates(tubificid and chironomid).The correlations between toxicity of sediment and the sediment quality guidelines(SQGs)derived previously were evaluated. There were significant correlations(p < 0.0001) between the observed toxicities and the total risk quotients of the heavy metals based on SQGs,indicating that threshold effect level(TEL) and probable effect level(PEL) were reliable to predict the toxicities of heavy metals in the sediments of Taihu Lake. By contrast, the method based on acid volatile sulfides(AVS) and simultaneously extracted metals(SEM),such as ∑SEM/AVS and ∑SEM-AVS, did not show correlations with the toxicities. Moreover,the predictive ability of SQGs was confirmed by a total predicting accuracy of 77%. Ecological risk assessment based on TELs and PELs showed that the contaminations of Pb, Cu, Cd and Zn in the sediments of Taihu Lake were at relatively low or medium levels. The risks caused by heavy metals in the sediments of northern bay of the lake, which received more wastewater discharge from upper stream, were higher than other area of the lake. | Yanfeng Zhang Yuwei Han Jinxi Yang Lingyan Zhu Wenjue Zhong | 2017 | Journal of Environmental Sciences2017，29，12： | 16 |
| 3 | Effects of Tai Ji Quan training on gait kinematics in older Chinese women with knee osteoarthritis: A randomized controlled trial显示文摘Background: Although Tai Ji Quan has been shown to relieve pain and improve functional mobility in people with knee osteoarthritis(OA), little is known about its potential benefits on gait characteristics among older Chinese women who have a high prevalence of both radiographic and symptomatic knee OA. This study aims to assess the efficacy of a tailored Tai Ji Quan intervention on gait kinematics for older Chinese women with knee OA.Methods: A randomized controlled trial involving 46 older women in Shanghai, China, with clinically diagnosed knee OA. Randomized(1:1)participants received either a 60 min Tai Ji Quan session(n = 23) 3 times weekly or a 60 min bi-weekly educational session(n = 23) for 24 weeks.Primary outcomes were changes in gait kinematic measures from baseline to 24 weeks. Secondary outcomes included changes in scores on the Western Ontario and Mc Master University Osteoarthritis Index(WOMAC) and Short Physical Performance Battery(SPPB).Results: After 24 weeks the Tai Ji Quan group demonstrated better performance in gait velocity(mean difference, 8.40 cm/s, p = 0.01), step length(mean difference, 3.52 cm, p = 0.004), initial contact angle(mean difference, 2.19°, p = 0.01), and maximal angle(mean difference, 2.61°,p = 0.003) of flexed knees during stance phase compared to the control group. In addition, the Tai Ji Quan group showed significant improvement in WOMAC scores(p < 0.01)(mean difference,-4.22 points in pain, p = 0.002;-2.41 points in stiffness, p < 0.001;-11.04 points in physical function, p = 0.006) and SPPB scores(mean difference, 1.22 points, p < 0.001).Conclusion: Among older Chinese women with knee OA, a tailored Tai Ji Quan intervention improved gait outcomes. The intervention also improved overall function as indexed by the WOMAC and SPPB. These results support the use of Tai Ji Quan for older Chinese adults with knee OA to both improve their functional mobility and reduce pain symptomatology. | Qingguang Zhu Lingyan Huang Xie Wu Lin Wang Yunya Zhang Min Fang Yu Liu JingXian Li | 2016 | Journal of Sport and Health Science2016，5，3： | 14 |
| 4 | Cyclostratigraphy of the Induan (Early Triassic) in West Pingdingshan Section,Chaohu,Anhui Province显示文摘The Induan sequence in the West Pingdingshan Section, Chaohu, Anhui Province, displays a series of superimposed mudstone/limestone cycles. The lithological character of the cycles, combined with power spectral and wavelet analysis of magnetic susceptibility readings, reveals 12 short eccentricity and 56 precession Milankovitch cycles - obliquity cycles are not apparent. The uniformity of cycle thicknesses indicates a stable depositional setting making this section ideal to perform various geo-logical studies. Accordingly, the Induan Stage is estimated to have lasted 1.1 Ma, and the depositional rate for this part of the section is about 3.7 cm/ka. This places the Induan-Olenekian boundary in the West Pingdingshan Section at about 251.5 Ma based on an age of 252.6 Ma for the Permian-Triassic boundary. | GUO Gang TONG JinNan ZHANG ShiHong ZHANG Jie BAI LingYan | 2008 | Science China Earth Sciences2008，51，1： | 10 |
| 5 | Preparation and evaluation of Fe_3O_4-core@Ag-shell nanoeggs for the development of fingerprints显示文摘The surface of individual, relatively dispersed Fe3O4 nanospheres is coated with a thiol-terminated silane, then the thiol on the Fe3O4 particles' surfaces treats with nano-Ag colloidal solution to form Ag-modified Fe3O4 nanoparticles. Eventually, a solid shell of Ag is capped onto the Ag-modified Fe3O4 nanoparticles by reducing aliquots of AgNO3 solution using NaBH4 as a reducing agent. The as-prepared Fe3O4 -core@Ag-shell nanoeggs, which are uniform in size, highly monodisperse, stable against aggregation and have high magnetization, were depended on thin shell of the attached nano-Ag, the size of Fe3O4 nanoparticles, the volume of thiol-terminated silane as well as the ultrasonication. The Fe3O4 -core@Ag-shell nanoeggs are proposed to detect fingermarks on different surface, with which the fingermarks can be viewed directly, due to the clear ridge detail. | ZHANG LingYan ZHOU XiaoFeng CHU Ting | 2013 | Science China Chemistry2013，56，5： | 7 |
| 6 | Source apportionment of PM_(2.5)light extinction in an urban atmosphere in China显示文摘Haze in China is primarily caused by high pollution of atmospheric fine particulates(PM2.5).However, the detailed source structures of PM2.5 light extinction have not been well established, especially for the roles of various organic aerosols, which makes haze management lack specified targets. This study obtained the mass concentrations of the chemical compositions and the light extinction coefficients of fine particles in the winter in Dongguan, Guangdong Province, using high time resolution aerosol observation instruments. We combined the positive matrix factor(PMF) analysis model of organic aerosols and the multiple linear regression method to establish a quantitative relationship model between the main chemical components, in particular the different sources of organic aerosols and the extinction coefficients of fine particles with a high goodness of fit(R^2= 0.953). The results show that the contribution rates of ammonium sulphate,ammonium nitrate, biomass burning organic aerosol(BBOA), secondary organic aerosol(SOA) and black carbon(BC) were 48.1%, 20.7%, 15.0%, 10.6%, and 5.6%, respectively. It can be seen that the contribution of the secondary aerosols is much higher than that of the primary aerosols(79.4% versus 20.6%) and are a major factor in the visibility decline. BBOA is found to have a high visibility destroying potential, with a high mass extinction coefficient, and was the largest contributor during some high pollution periods. A more detailed analysis indicates that the contribution of the enhanced absorption caused by BC mixing state was approximately 37.7% of the total particle absorption and should not be neglected. | Zijuan Lan Bin Zhang Xiaofeng Huang Qiao Zhu Jinfeng Yuan Liwu Zeng Min Hu Lingyan He | 2018 | Journal of Environmental Sciences2018，30，1： | 7 |
| 7 | High-throughput experiments facilitate materials innovation:A review显示文摘Since the Material Genome Initiative(MGI) was proposed, high-throughput based technology has been widely employed in various fields of materials science. As a theoretical guide, material informatics has been introduced based on machine learning and data mining and high-throughput computation has been employed for large scale search, narrowing down the scope of the experiment trials. High-throughput materials experiments including synthesis, processing, and characterization technologies have become valuable research tools to pin down the prediction experimentally, enabling the discovery-to-deployment of advances materials more efficiently at a fraction of cost. This review aims to summarize the recent advances of high-throughput materials experiments and introduce briefly the development of materials design based on material genome concept. By selecting representative and classic works in the past years, various high-throughput preparation methods are introduced for different types of material gradient libraries, including metallic, inorganic materials, and polymers. Furthermore, high-throughput characterization approaches are comprehensively discussed, including both their advantages and limitations. Specifically, we focus on high-throughput mass spectrometry to analyze its current status and challenges in the application of catalysts screening. | LIU Yi Hao HU ZiHeng SUO ZhiGuang HU LianZhe FENG LingYan GONG XiuQing LIU Yi ZHANG JinCang | 2019 | Science China(Technological Sciences)2019，62，4： | 7 |

| 9 | Allele-aware chromosome-scale assembly of the allopolyploid genome of hexaploid Ma bamboo(Dendrocalamus latiflorus Munro)显示文摘Dendrocalamus latiflorus Munro is a woody clumping bamboo with rapid shoot growth.Both genetic transformation and clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9)gene editing techniques are available for D.latiflorus,enabling reverse genetic approaches.Thus,D.latiflorus has the potential to be a model bamboo species.However,the genome sequence of D.latiflorus has remained unreported due to its polyploidy and large genome size.Here,we sequenced the D.latiflorus genome and assembled it into three allele-aware subgenomes(AABBCC),representingthe largest genome of a major bamboo species.We assembled 70 allelic chromosomes(2,737 Mb)for hexaploid D.latiflorus using both singlemolecule sequencing from the Pacific Biosciences(Pac Bio)Sequel platform and chromosome conformation capture sequencing(Hi-C).Repetitive sequences comprised 52.65%of the D.latiflorus genome.We annotated 135231 protein-coding genes in the genome based on transcriptomes from eight different tissues.Transcriptome sequencing using RNA-Seq and Pac Bio singlemolecule real-time long-read isoform sequencing revealed highly differential alternative splicing(AS)between non-abortive and abortive shoots,suggesting that AS regulates the abortion rate of bamboo shoots.This high-quality hexaploid genome and comprehensive strand-specific transcriptome datasets for this Poaceae family member will pave the way for bamboo research using D.latiflorus as a model species. | Yushan Zheng Deming Yang Jundong Rong Liguang Chen Qiang Zhu Tianyou He Lingyan Chen Jing Ye Lili Fan Yubang Gao Hangxiao Zhang Lianfeng Gu | 2022 | Journal of Integrative Plant Biology2022，64，3： | 6 |
| 10 | L-tyrosine improves neuroendocrine function in a mouse model of chronic stress显示文摘Adult BALB/c mice, individually housed, were stimulated with nine different stressors, arranged randomly, for 4 continuous weeks to generate an animal model of chronic stress. In chronically stressed mice, spontaneous locomotor activity was significantly decreased, escape latency in the Morris water maze test was prolonged, serum levels of total thyrotropin and total triiodothyronine were significantly decreased, and dopamine and norepinephrine content in the pallium, hippocampus and hypothalamus were significantly reduced. All of these changes were suppressed, to varying degrees, by L-tyrosine supplementation. These findings indicate that the neuroendocrine network plays an important role in chronic stress, and that L-tyrosine supplementation has therapeutic effects. | Zhihua Wang Jinghua Li Zhiming Wang Lingyan Xue Yi Zhang Yingjie Chen Jun Su Zhongming Li | 2012 | Neural Regeneration Research2012，7，18： | 5 |
| 11 | Chemical Components, Variation, and Source Identification of PM1 during the Heavy Air Pollution Episodes in Beijing in December 2016显示文摘Air pollution is a current global concern. The heavy air pollution episodes(HPEs) in Beijing in December 2016 severely influenced visibility and public health. This study aims to survey the chemical compositions, sources, and formation processes of the HPEs. An aerodyne quadruple aerosol mass spectrometer(Q-AMS) was utilized to measure the non-refractory PM1(NR-PM1) mass concentration and size distributions of the main chemical components including organics, sulfate, nitrate, ammonium, and chloride in situ during 15–23 December 2016. The NR-PM1 mass concentration was found to increase from 6 to 188 μg m–3 within 5 days. During the most serious polluted episode, the PM1 mass concentration was about 2.6 times that during the first pollution stage and even 40 times that of the clean days. The formation rates of PM2.5 in the five pollution stages were 26, 22, 22, 32, and 67 μg m^(–3) h–1, respectively. Organics and nitrate occupied the largest proportion in the polluted episodes, whereas organics and sulfate dominated the submicron aerosol during the clean days. The size distribution of organics is always broader than those of other species, especially in the clean episodes. The peak sizes of the interested species grew gradually during different HPEs. Aqueous reaction might be important in forming sulfate and chloride, and nitrate was formed via oxidization and condensation processes. PMF(positive matrix factorization) analysis on AMS mass spectra was employed to separate the organics into different subtypes. Two types of secondary organic aerosol with different degrees of oxidation consisted of 43% of total organics. By contrast, primary organics from cooking, coal combustion, and traffic emissions comprised 57% of the organic aerosols during the HPEs. | Yangmei ZHANG Yaqiang WANG Xiaoye ZHANG Xiaojing SHEN Junying SUN Lingyan WU Zhouxiang ZHANG Haochi CHE | 2018 | Journal of Meteorological Research2018，32，1： | 4 |
| 12 | Prognostic value of interim ^(18)F-FDG PET/CT in diffuse large B-cell lymphoma显示文摘Objective: Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease. The prognostic factor currently used is not accurate enough to predict the outcomes of patients with DLBCL. The prognostic significance of interim PET/CT in DLBCL remains controversial. The aim of this study is to determine the predictive value of interim 18F-FDG PET/CT after first-line treatment in patients with DLBCL. Methods: Thirty-two patients with DLBCL underwent baseline, interim and post-treatment 18F-FDG PET/CT scans. Imaging results were analyzed for the survival of patients via software SPSS 13.0, retrospectively. Results: Thirty-one of the 32 patients were treated with R-CHOP regimen, and interim 18F-FDG PET/CT of 24 patients was performed after 2 cycles of treatment. After a median follow-up period of 16.7 months, the 2-year progression-free survival (PFS) rates were significantly different between the groups above and below SUV max cut-off value of 2.5 (P=0.039). No significant differences were found in the 2-year PFS rates if SUV max cut-off values were set as 2.0 and 3.0, respectively (P=0.360; P=0.113). Conclusions: Interim PET/CT could predict the prognosis of DLBCL patients with the SUV max cut-off value of 2.5, but more clinical data should be concluded to confirm this conclusion. | Zhitao Ying Xuejuan Wang Yuqin Song Wen Zheng Xiaopei Wang Yan Xie Ningjing Lin Meifeng Tu Lingyan Ping Weiping Liu Lijuan Deng Chen Zhang Zhi Yang Jun Zhu | 2013 | Chinese Journal of Cancer Research2013，25，1： | 4 |

| 14 | Locomotor activity and anxiety status, but not spatial working memory,are affected in mice after brief exposure to cuprizone显示文摘Chronic long-term exposure to cuprizone causes severe brain demyelination in mice,which leads to changes in locomotion,working memory and anxiety.These findings suggest the importance of intact myelin for these behaviors.This study aimed to investigate the possible behavioral changes in mice with mild oligodendrocyte/myelin damage that parallels the white matter changes seen in the brains of patients with psychiatric disporders.We used the cuprizonetreated mouse model to test both tissue changes and behavioral functions(locomotor activity,anxiety status,and spatial working memory).The results showed that mice given cuprizone in their diet for 7 days had no significant myelin breakdown as evaluated by immunohistochemical staining for myelin basic protein,while the number of mature oligodendrocytes was reduced.The number and length of Caspr protein clusters,a structural marker of the node of Ranvier,did not change.The locomotor activity of the cuprizonetreated mice increased whereas their anxiety levels were lower than in normal controls;spatial working memory,however,did not change.These results,for the first time,link emotion-related behavior with mild white matter damage in cuprizone-treated mice. | Handi Zhang Yanbo Zhang Haiyun Xu Lingyan Wang Jinsong Zhao Junhui Wang Zhijun Zhang Qingrong Tan Jiming Kong Qingjun Huang Xin-Min Li | 2013 | Neuroscience Bulletin2013，29，5： | 4 |

| 16 | Prognostic value of pre-and post-transplantation 18F-fluorodeoxyglucose positron emission tomography results in non-Hodgkin lymphoma patients receiving autologous stem cell transplantation显示文摘Objective: High-dose chemotherapy(HDC) followed by autologous stem cell transplantation(ASCT) is the standard of care in the upfront or relapsed/refractory setting in some patients with non-Hodgkin lymphoma(NHL).However,a proportion of patients do not respond to ASCT.^(18)F-fluorodeoxyglucose(FDG) positron emission tomography(PET)/computed tomography(CT) has been widely used for staging,response evaluation,and prognosis prediction.Here,we investigated the prognostic role of PET/CT in NHL patients before and after ASCT.Methods: A retrospective study was conducted at Peking University Cancer Hospital.All NHL patients who underwent ASCT between March 2010 and July 2016 were identified.Patients who had PET/CT scan before and after ASCT were included.Deauville criteria(5-point scale) were used to interpret PET scans.Univariate and multivariate survival analyses were performed using Cox regression.The predictive value of PET scanning was estimated by comparing the area under the receiver operating characteristic(ROC) curve.Results: In total,79 patients were enrolled in this study.In univariate analysis,pre-and post-ASCT PET result was identified as prognostic factors for 3-year progression-free survival(PFS) and overall survival(OS).Patients with negative pre-ASCT PET result demonstrated significantly better PFS(84.2% vs.54.2%) and OS(89.2% vs.63.6%) than patients with positive pre-ASCT PET result.PFS(91.6% vs.25.3%) and OS(96.5% vs.36.8%) were also significantly different between patients with negative and positive post-ASCT PET result.Multivariate analysis also showed a significant association between survival and post-ASCT PET result.ROC analysis revealed that the predictive value of post-ASCT PET result was superior to that of pre-ASCT PET result alone.Combined pre-and post-ASCT PET result is better for predicting outcomes in patients with NHL receiving transplantation.Deauville criteria score >3 was identified as the best cutoff value for post-ASCT PET.Conclusions: Post-ASCT PET result was more important than pre-ASCT PET result in predicting outcomes for NHL patients who underwent ASCT.The prognostic significance can be improved when combining preASCT PET result with post-ASCT PET result.Deauville criteria can be used for interpreting PET scans in this scenario. | Zhitao Ying Lan Mi Xuejuan Wang Yuewei Zhang Zhi Yang Yuqin Song Xiaopei Wang WenZheng Ningjing Lin Meifeng Tu Yan Xie Lingyan Ping Chen Zhang Weiping Liu LijuanDeng Jun Zhu | 2017 | Chinese Journal of Cancer Research2017，29，6： | 3 |
| 17 | Comparative sorption and desorption behaviors of PFHx S and PFOS on sequentially extracted humic substances显示文摘The sorption and desorption behaviors of two perfluoroalkane sulfonates(PFSAs),including perfluorohexane sulfonate(PFHx S)and perfluorooctane sulfonate(PFOS)on two humic acids(HAs)and humin(HM),which were extracted from a peat soil,were investigated.The sorption kinetics and isotherms showed that the sorption of PFOS on the humic substances(HSs)was much higher than PFHx S.For the same PFSA compound,the sorption on HSs followed the order of HM>HA2>HA1.These suggest that hydrophobic interaction plays a key role in the sorption of PFSAs on HSs.The sorption capacities of PFSAs on HSs were significantly related to their aliphaticity,but negatively correlated to aromatic carbons,indicating the importance of aliphatic groups in the sorption of PFSAs.Compared to PFOS,PFHx S displayed distinct desorption hysteresis,probably due to irreversible pore deformation after sorption of PFHx S.The sorption of the two PFSAs on HSs decreased with an increase in p H in the solution.This is ascribed to the electrostatic interaction and hydrogen bonding at lower p H.Hydrophobic interaction might also be stronger at lower p H due to the aggregation of HSs. | Lixia Zhao Yifeng Zhang Shuhong Fang Lingyan Zhu Zhengtao Liu | 2014 | Journal of Environmental Sciences2014，26，12： | 3 |
| 18 | High-order maximum-principle-preserving and positivity-preserving weighted compact nonlinear schemes for hyperbolic conservation laws显示文摘In this paper,the maximum-principle-preserving(MPP)and positivitypreserving(PP)flux limiting technique will be generalized to a class of high-order weighted compact nonlinear schemes(WCNSs)for scalar conservation laws and the compressible Euler systems in both one and two dimensions.The main idea of the present method is to rewrite the scheme in a conservative form,and then define the local limiting parameters via case-by-case discussion.Smooth test problems are presented to demonstrate that the proposed MPP/PP WCNSs incorporating a third-order Runge-Kutta method can attain the desired order of accuracy.Other test problems with strong shocks and high pressure and density ratios are also conducted to testify the performance of the schemes. | Lingyan TANG Songhe SONG Hong ZHANG | 2020 | Applied Mathematics and Mechanics(English Edition)2020，41，1： | 3 |
| 19 | Syntenic quantitative trait loci and genomic divergence for Sclerotinia resistance and ?owering time in Brassica napus显示文摘Oilseed rape(Brassica napus) is an allotetraploid with two subgenomes descended from a common ancestor. Accordingly, its genome contains syntenic regions with many duplicate genes, some of which may have retained their original functions, whereas others may have diverged. Here, we mapped quantitative trait loci(QTL) for stem rot resistance(SRR), a disease caused by the fungus Sclerotinia sclerotiorum, and flowering time(FT) in a recombinant inbred line population. The population was genotyped using B.napus 60 K single nucleotide polymorphism arrays and phenotyped in six(FT) and nine(SSR) experimental conditions or environments. In total, we detected 30 SRR QTL and 22 FT QTL and show that some of the major QTL associated with these two traits were co-localized,suggesting a genetic linkage between them. Two SRR QTL on chromosome A2 and two on chromosome C2 were shown to be syntenic, suggesting the functional conservation of these regions. We used the syntenic properties of the genomic regions to exclude genes for selection candidates responsible for QTL-associated traits. For example, 152 of the 185 genes could be excluded from a syntenic A2–C2 region. These findings will help to elucidate polyploid genomics in future studies, in addition to providing useful information for B. napus breeding programs. | Fengqi Zhang Junyan Huang Minqiang Tang Xiaohui Cheng Yueying Liu Chaobo Tong Jingyin Yu Tehrim Sadia Caihua Dong Lingyan Liu Baojun Tang Jianguo Chen Shengyi Liu | 2019 | Journal of Integrative Plant Biology2019，61，1： | 3 |
| 20 | Different Mortality Effects of Extreme Temperature Stress in Three Large City Clusters of Northern and Southern China显示文摘Extreme temperature events have affected Chinese city residents more frequently and intensively since the early 2000 s, but few studies have identified the impacts of extreme temperature on mortality in different city clusters of China. This study first used a distributed lag,nonlinear model to estimate the county/district-specific effects of extreme temperature on nonaccidental and cardiovascular mortality. The authors then applied a multivariate meta-analysis to pool the estimated effects in order to derive regional temperature–mortality relationship in three large city clusters—the Beijing-Tianjin-Hebei(BTH)region, the Yangtze River Delta(YRD), and the Pearl River Delta(PRD), which represent northern and southern regions. With 0–3 days' lag, the strongest heat-related mortality effect was observed in the BTH region(with relative risk(RR) of 1.29; 95% confidence interval(CI):1.13–1.47), followed by the YRD(RR = 1.25; 95% CI:1.13–1.35) and the PRD(RR = 1.14; 95% CI: 1.01–1.28)areas. With 0–21 days' lag, the cold effect was pronounced in all city clusters, with the highest extreme cold-related mortality risk found in the PRD area(RR = 2.27; 95% CI:1.63–3.16), followed by the YRD area(RR = 1.85; 95%CI: 1.56–2.20) and BTH region(RR = 1.33; 95% CI:0.96–1.83). People in the southern regions tended to be more vulnerable to cold stress, but the northern population was more sensitive to heat stress. By examining the effects of extreme temperature in city clusters of different regions,our findings underline the role of adaptation towards heat and cold, which has important implications for public health policy making and practice. | Lingyan Zhang Zhao Zhang Chenzhi Wang Maigeng Zhou Peng Yin | 2017 | International Journal of Disaster Risk Science2017，8，4： | 3 |
