| 1 | Wet and dry deposition fluxes of heavy metals in Pearl River Delta Region(China):Characteristics,ecological risk assessment,and source apportionment显示文摘The atmospheric deposition of heavy metals poses serious risks to the ecological system and human health. To advance our knowledge of atmospheric dry/wet heavy metal deposition in the PRD region, monthly fluxes were examined based on soluble/insoluble fractions of five heavy metal elements(Cu, Pb, Cd, Cr and Zn) in samples collected from January 2014 to December 2015 at Guangzhou(urban) and Dinghushan(suburban) sites. The ratios of wet/dry deposition fluxes indicated that heavy metal deposition was governed by wet deposition rather than dry deposition in the PRD region. Affected by the shifting of the Asian monsoon, wet deposition fluxes exhibited significant seasonal variation between summer monsoon seasons(April to September) and winter monsoon seasons(October to February) in this region. Cd was classified as an extremely strong potential ecological risk based on solubility and the Hakanson ecological risk index. Source contributions to wet deposition were calculated by PMF, suggesting that dust, biomass burning, industries,vehicles, long-range transport and marine aerosol sources in Guangzhou, and Zn fertilizers,marine aerosol sources, agriculture, incense burning, biomass burning, vehicles and the ceramics industry in Dinghushan, were the potential sources of heavy metals. | Lyumeng Ye Minjuan Huang Buqing Zhong Xuemei Wang Qiulan Tu Haoran Sun Chao Wang Luolin Wu Ming Chang | 2018 | Journal of Environmental Sciences2018，30，8： | 20 |
| 2 | Epidemiological Characteristics of Human Brucellosis-China,2016−2019显示文摘Introduction:Brucellosis is an important zoonotic infectious disease with its main mode of transmission from livestock to humans.The study analyzed epidemiological characteristics of human brucellosis from 2016 to 2019 in China,aiming to understand progress of the National Program of Brucellosis Prevention and Control.Methods:The research obtained data on human brucellosis cases reported through China’s National Notifiable Disease Reporting System(NNDRS)from January 1,2016 to December 31,2019 and described brucellosis epidemiological patterns by region,seasonality,age,sex,and occupation.Results:The number of cases reported nationwide in China decreased from 47,139(3.4/100,000)in 2016 to 37,947(2.7/100,000)in 2018,and then increased to 44,036(3.2/100,000)in 2019,with an average annual incidence of 3.0/100,000 during the four study years.Brucellosis in Xinjiang declined from 35.6/100,000 in 2016 to 16.3/100,000 in 2019-an average annual decrease of 22.9%.Brucellosis in Inner Mongolia increased from 23.8/100,000 in 2016 to 54.4/100,000 in 2019-an average increase of 31.8%per year and accounting for 22%of all reported cases.Northern China reported 95.2%of cases during this period and still had an incidence of 7.2/100,000 and 87.0%of counties being affected by brucellosis in 2019.In this region in 2019,males aged 45-64 years old had an incidence of over 15.9/100,000,compared with over 7.0/100,000 among females aged 45-64 years old.Conclusions:Although there was progress in prevention and control of human brucellosis in some provincial-level administrative divisions(PLADs)in 2016 through 2019,progress was limited nationwide and there was an overall resurgence of brucellosis in 2019.The resurgence was primarily in Inner Mongolia.An One Health approach should be strengthened to ensure successful and sustainable brucellosis prevention and control in China. | Zhongfa Tao Qiulan Chen Yishan Chen Yu Li Di Mu Huimin Yang Wenwu Yin | 2021 | China CDC weekly2021，3，6： | 6 |
| 3 | Transmission and mortality risk assessment of severe fever with thrombocytopenia syndrome in China:results from 11-years’study显示文摘Background: The transmission and fatal risk of severe fever with thrombocytopenia syndrome (SFTS), an emerging infectious disease first discovered in China in 2009, still needed further quantification. This research aimed to analyze the SFTS clusters and assess the transmission and mortality risk for SFTS.Methods: Both epidemiological investigation and case reports regarding SFTS clusters in China during 2011-2021 were obtained from the Public Health Emergency Information Management System of the Chinese Center for Disease Control and Prevention Information System. The transmission risk was evaluated by using the secondary attack rate (SAR) and relative risk (RR). Mortality risk factors were analyzed using a logistic regression model.Results: There were 35 SFTS clusters during 2011-2021 involving 118 patients with a fatality rate of 22.0%. The number of clusters annually increased seasonally from April to September. The clusters mainly occurred in Anhui (16 clusters) and Shandong provinces (8 clusters). The SAR through contact with blood or bloody fluids was much higher than that through contact with non-bloody fluids (50.6% vs 3.0%;χ^(2) = 210.97,P < 0.05), with anRR of 16.61 [95% confidence interval (CI): 10.23-26.97]. There was a statistically significant difference in the SAR between exposure to the blood of a deceased person during burial preparation and exposure to the living patients’ blood (66.7% vs 34.5%;χ^(2)= 6.40,P < 0.05), with anRR of 1.93 (95%CI: 1.11-3.37). The mortality risk factors were a long interval from onset to diagnosis [odds ratio (OR)= 1.385), 95%CI: 1.083-1.772,P= 0.009) and advanced age (OR: 1.095, 95%CI: 1.031-1.163,P= 0.01).Conclusions: The SFTS clusters showed a high mortality rate and resulted in a high SAR. Contact with a bleeding corpse was associated with a higher infection risk, compared with contacting the blood from living patients. It is important to promote early detection and appropriate case management of patients with SFTS, as well as improved handling of their corpses, to prevent further transmission and mortality. | Qiulan Chen Dong Yang Yanping Zhang Mantong Zhu Ning Chen Zainawudong Yushan | 2022 | Infectious Diseases of Poverty2022，11，5： | 2 |
| 4 | Human Brucellosis:An Ongoing Global Health Challenge显示文摘Brucellosis is one of the most common zoonotic diseases,caused by species of the genus Brucella,that affects domestic and farm livestock and a wide range of wild mammals(1-2).Endemic areas are primarily located in the low-and middle-income countries across the Mediterranean region,the Arabian Peninsula,Africa,Asia,and Central and South America,with major regional differences(3-5).The highest prevalence in animals was observed in countries of the Middle East and sub-Saharan Africa,China。 | Shengjie Lai Qiulan Chen Zhongjie Li | 2021 | China CDC weekly2021，3，6： | 2 |
| 5 | One-step preparation of branched PEG functionalized AIE-active luminescent polymeric nanoprobes显示文摘The synthesis of amphiphilic aggregation-induced emission(AIE) dyes based organic nanoparticles has recently attracted increasing attention in the biomedical fields. These AIE dyes based nanoparticles could effectively overcome the aggregation caused quenching effect of conventional organic dyes, making them promising candidates for fabrication of ultrabright organic luminescent nanomaterials. In this work, AIE-active luminescent polymeric nanoparticles(4-NH_2-PEG-TPE-E LPNs) were facilely fabricated through Michael addition reaction between tetraphenylethene acrylate(TPE-E) and 4-arm-poly(ethylene glycol)-amine(4-NH_2-PEG) in rather mild ambient. The 4-NH_2-PEG can not only endow these AIE-active LPNs good water dispersibility, but also provide functional groups for further conjugation reaction. The size, morphology and luminescent properties of 4-NH_2-PEG-TPE-E LPNs were characterized by a series of techniques in detail. Results suggested that these AIE-active LPNs showed spherical morphology with diameter about 100–200 nm. The obtained 4-NH_2-PEG-TPE-E LPNs display high water dispersibility and strong fluorescence intensity because of their self assembly and AIE properties of TPE-E.Biological evaluation results demonstrated that 4-NH_2-PEG-TPE-E LPNs showed negative toxicity toward cancer cells and good fluorescent imaging performance. All of these features make 4-NH_2-PEG-TPE-E LPNs promising candidates for biological imaging and therapeutic applications. | Jun Chu Qiulan Lv Chunliang Guo Dazhuang Xu Ke Wang Meiying Liu Hongye Huang Xiaoyong Zhang Yen Wei | 2016 | Science China Chemistry2016，59，8： | 2 |
