| 1 | Distribution and characteristic of PAHs in snow of Fildes Peninsula显示文摘Polycyclic aromatic hydrocarbons (PAHs) investigation in different matrices has been reported largely,whereas reports on snow samples were limited.Snow,as the main matrix in the polar region,has an important study meaning.PAHs in snow samples were analyzed to investigate the distribution and contamination status of them in the Antarctic,as well as to provide some references for global migration of PAHs.Snow samples collected in Fildes Peninsula were enriched and separated by solid-phase membrane disks and eluted by methylene dichloride,then quantified by gas chromatography/mass spectrometry.All types of PAHs were detected except for Benzo(a)pyrene.Principal component analysis method was applied to characterize them.Three factors (Naphthalene,Fluorene and Phenanthrene) accounted for 60.57%,21.61% and 9.80%,respectively.The results showed that the major PAHs sources maybe the atmospheric transportation,and the combustion of fuel in Fildes Peninsula.The comparison of concentration and types of PAHs between accumulated snow and fresh snow showed that the main compound concentrations in accumulated snow samples were higher than those in fresh ones.The risk assessment indicated that the amount of PAHs in the snow samples would not lead to ecological risk. | Guangshui Na Chunyang Liu Zhen Wang Linke Ge Xindong Ma Ziwei Yao | 2011 | Journal of Environmental Sciences2011，23，9： | 8 |
| 2 | Flexible, Porous, and Metal–Heteroatom?Doped Carbon Nanofibers as Efficient ORR Electrocatalysts for Zn–Air Battery显示文摘Developing an e cient and durable oxygen reduction electrocatalyst is critical for clean-energy technology, such as fuel cells and metal–air batteries. In this study, we developed a facile strategy for the preparation of flexible, porous, and well-dispersed metal–heteroatom-doped carbon nanofibers by direct carbonization of electrospun Zn/Co-ZIFs/PAN nanofibers(Zn/Co-ZIFs/PAN). The obtained Zn/Co and N co-doped porous carbon nanofibers carbonized at 800 °C(Zn/Co–N@PCNFs-800) presented a good flexibility, a continuous porous structure, and a superior oxygen reduction reaction(ORR) catalytic activity to that of commercial 20 wt% Pt/C, in terms of its onset potential(0.98 V vs. RHE), half-wave potential(0.89 V vs. RHE), and limiting current density(-5.26 mA cm^(-2)). In addition, we tested the suitability and durability of Zn/Co–N@PCNFs-800 as the oxygen cathode for a rechargeable Zn–air battery. The prepared Zn–air batteries exhibited a higher power density(83.5 mW cm^(-2)), a higher specific capacity(640.3 mAh g^(-1)), an excellent reversibility, and a better cycling life than the commercial 20 wt% Pt/C + RuO_2 catalysts. This design strategy of flexible porous non-precious metal-doped ORR electrocatalysts obtained from electrospun ZIFs/polymer nanofibers could be extended to fabricate other novel, stable, and easy-to-use multi-functional electrocatalysts for clean-energy technology. | Qijian Niu Binling Chen Junxia Guo Jun Nie Xindong Guo Guiping Ma | 2019 | Nano-Micro Letters2019，11，1： | 7 |
| 3 | Occurrence and bioaccumulation of polybrominated diphenyl ethers in sediments and paddy ecosystems of Liaohe River Basin, northeast China显示文摘Concentrations of 16 polybrominated diphenyl ether(PBDE) congeners were measured in river sediments, paddy soils and three species of paddy-field organisms(crab, loach and carp) collected from the Liaohe River Basin, northeastern China. The total contents of PBDEs(∑_(16)PBDEs) in sediments and paddy soils were in the ranges of 273.4–3246.3 pg/g dry weight(dw), and 192.1–1783.8 pg/g dw, respectively. BDE 209 was the dominant congener both in sediments and paddy soils. The concentrations of ∑_(16)PBDEs in sediments were significantly higher than those in the adjacent paddy soils, indicating a potential transport of PBDEs from river to paddy ecosystems via river water irrigation. The biota–soil accumulation factor(BSAF) was calculated as the ratio between the lipid-normalized concentration in paddyfield organisms and the total organic carbon-normalized concentration in paddy soil. The average BSAF values of ∑15PBDEs followed the sequence of crab(3.6) > loach(3.3) > carp(2.1). BDE 154 had the highest BSAF value, and a parabolic trend between BSAF values of individual PBDE congeners and their log KOWvalues was observed. In view of the fact that crab had the larger BSAF value and higher lipid content, the ecological risk and health risk for crab cultivation in paddy fields should be of particular concern. | Xindong Ma Haijun Zhang Wenjun Yao Wen Guo Depeng Li Ziwei Yao Jiping Chen | 2016 | Journal of Environmental Sciences2016，28，5： | 6 |
| 4 | Pathological changes in the lungs and lymphatic organs of 12 COVID-19 autopsy cases显示文摘Systematic autopsy and comprehensive pathological analyses of COVID-19 decedents should provide insights into the disease characteristics and facilitate the development of novel therapeutics.In this study,we report the autopsy findings from the lungs and lymphatic organs of 12 COVID-19 decedents—findings that evaluated histopathological changes;immune cell signature and inflammatory factor expression in the lungs,spleen and lymph nodes.Here we show that the major pulmonary alterations included diffuse alveolar damage,interstitial fibrosis and exudative inflammation featured with extensive serous and fibrin exudates,macrophage infiltration and abundant production of inflammatory factors(IL-6,IP-10,TNFo?and IL-I f).The spleen and hilar lymph nodes contained lesions with tissue structure disruption and immune cell dysregulation,including lymphopenia and macrophage accumulation.These findings provide pathological evidence that links injuries of the lungs and lymphatic organs with the fatal systematic respiratory and immune malfunction in critically ill COVID-19 patients. | Qian Liu Yu Shi Jun Cai Yaqi Duan Rongshuai Wang Hongyan Zhang Qiurong Ruan Jiansha Li Lei Zhao Yifang Ping Rong Chen Liang Ren Xiaochun Fei Heng Zhang Rui Tang Xi Wang Tao Luo Xindong Liu Xuequan Huang Zhenhua Liu Qilin Ao Yong Ren Jing Xiong Zhicheng He Haibo Wu Wenjuan Fu Pengnan Zhao Xinwei Chen Guoqiang Qu Yunyun Wang Xi Wang Jia Liu Dongfang Xiang Sanpeng Xu Xiaowei Zhou Qingrui Li Jinghong Ma Heng Li Jie Zhang Sizhe Huang Xiaohong Yao Yiwu Zhou Chaofu Wang Dingyu Zhang Guoping Wang Liang Liu Xiu-Wu Bian | 2020 | National Science Review2020，7，12： | 6 |
| 5 | COVID-19-associated monocytic encephalitis(CAME):histological and proteomic evidence from autopsy显示文摘Severe neurological symptoms are associated with Coronavirus disease 2019(COVID-19).However,the morphologic features,pathological nature and their potential mechanisms in patient brains have not been revealed despite evidence of neurotropic infection.In this study,neuropathological damages and infiltrating inflammatory cells were quantitatively evaluated by immunohistochemical staining,ultrastructural examination under electron microscopy,and an image threshold method,in postmortem brains from nine critically ill COVID-19 patients and nine age-matched cadavers of healthy individuals.Differentially expressed proteins were identified by quantitative proteomic assays.Histopathological findings included neurophagocytosis,microglia nodules,satellite phenomena,extensive edema,focal hemorrhage,and infarction,as well as infiltrating mononuclear cells.Immunostaining of COVID-19 brains revealed extensive activation of both microglia and astrocytes,severe damage of the blood-brain barrier(BBB)and various degrees of perivascular infiltration by predominantly CD14+/CD16+/CD141+/CCR7+/CD11c+monocytes and occasionally CD4+/CD8+T lymphocytes.Quantitative proteomic assays combined with bioinformatics analysis identified upregulated proteins predominantly involved in immune responses,autophagy and cellular metabolism in COVID-19 patient brains compared with control brains.Proteins involved in brain development,neuroprotection,and extracellular matrix proteins of the basement membrane were downregulated,potentially caused by the activation of transforming growth factorβreceptor and vascular endothelial growth factor signaling pathways.Thus,our results define histopathological and molecular profiles of COVID-19-associated monocytic encephalitis(CAME)and suggest potential therapeutic targets. | Pei-Pei Zhang Zhi-Cheng He Xiao-Hong Yao Rui Tang Jie Ma Tao Luo Chuhong Zhu Tian-Ran Li Xindong Liu Dingyu Zhang Shuyang Zhang Yi-Fang Ping Ling Leng Xiu-Wu Bian | 2023 | Signal Transduction and Targeted Therapy2023，8，2： | 3 |
| 6 | Distribution characteristics and indicator significance of Dechloranes in multi-matrices at Ny-lesund in the Arctic显示文摘In recent years, Dechloranes have been widely detected in the environment around the world.However, understanding and knowledge of Dechloranes in remote regions, such as the Arctic,remain lacking. Therefore, the concentrations of 5 Dechloranes in surface seawater, sediment,soil, moss, and dung collected from Ny-lesund in the Arctic were measured with the concentrations 93 pg/L, 342, 325, 1.4, and 258 pg/g, respectively, which were much lower than those in Asian and European regions. The mean ratios of anti-Dechlorane Plus(DP) to total DP(fanti) in seawater, sediment, soil, moss, dung, and atmospheric samples were 0.36, 0.21, 0.18,0.27, 0.66, and 0.43, respectively. Results suggested that the main source of DP in seawater,sediment, soil, and moss was long-range atmospheric transport. However, the ratio identified in dung was different, for which the migration behavior of the organism is probably the main source of DP. | Guangshui Na Wei Wei Shiyao Zhou Hui Gao Xindong Ma Lina Qiu Linke Ge Chenguang Bao Ziwei Yao | 2015 | Journal of Environmental Sciences2015，27，2： | 3 |
| 7 | Jiawei Xiaoyao capsule treatment for mild to moderate major depression with anxiety symptoms: a randomized, double-blind, double-dummy, controlled, multicenter, parallel-treatment trial显示文摘OBJECTIVE:To assess the efficacy and safety of Jiawei Xiaoyao (JWXY) capsules on mild to moderate depression with anxiety symptoms,a randomized,double-blind,double-dummy controlled,multicenter,parallel-treatment trial was carried out among 210 outpatients with mild to moderate depression and anxiety symptoms from three hospitals in Beijing China.METHODS:Participants were randomized into the JWXY group or the sertraline group.Each group received JWXY treatment and sertraline placebo,or sertraline and JWXY placebo for 8 weeks.Main outcomes were measured using the Hamilton Depression Rating Scale (HAMD),Hamilton Anxiety Rating Scale (HAMA) and the Clinical Global Impression Scale.RESULTS:JWXY and sertraline had the equivalent effect on HAMD at every interview point.JWXY was more effective at reducing the HAMA scores at the 2nd and 12th week,HAMD sleep disturbance subscale scores at the 8th and 12th week,and HAMA somatic anxiety subscale scores at the 12th week.The rate of adverse events in the two groups was the same.CONCLUSION:For mild to moderate depression with anxiety symptoms,JWXY could be as effective as sertraline in alleviating depressive symptoms.For anxiety symptoms,JWXY may be effective more quickly and with longer lasting effects than sertraline.In particular,it may also improve quality of sleep and somatic anxiety symptoms.JWXY is safe and cheaper than conventional antidepressants,and may be the first alternative choice for depression with anxiety symptoms. | Su Rui Fan Jiping Li Tao Cao Xindong Zhou Jie Han Zhenyun Ma Yan | 2019 | Journal of Traditional Chinese Medicine2019，39，3： | 2 |
| 8 | Presence of organophosphate flame retardants(OPEs)in different functional areas in residential homes in Beijing,China显示文摘The production and application of organophosphate esters(OPEs)have dramatically increased in recent years due to their use as a replacement for brominated flame retardants.In this study,13 OPEs(∑_(13)OPEs)were analyzed in indoor air samples from kitchens and living rooms in 14 residential homes in Beijing,China.The concentrations of ∑_(13)OPEs in kitchen air samples(mean:13 ng/m^(3))were significantly(p<0.05)higher than in living room air samples(5.0 ng/m^(3)).In addition,paired window surface organic film samples were collected and analyzed to investigate film-air partitioning,exhibiting a mean concentration of ∑_(13)OPEs of 4100 ng/m^(2).The congener profiles showed that tris(2-chloroisopropyl)phosphate(TCPP)was the predominant compound in both window film samples(48%)and the corresponding indoor air sample(56%).The estimated daily intakes(EDI)of OPEs via indoor air inhalation were 2.8 and 1.4 ng/kg/day for infants and adults,respectively,both of which are below the reference dose values(RfDs).Overall,these findings indicate that OPEs in the indoor air environment of residential homes in Beijing are not likely to pose a health risk to the general population. | Kun Lv Lu Bai Boyu Song Xindong Ma Minmin Hou Jie Fu Yali Shi Yawei Wang Guibin Jiang | 2022 | Journal of Environmental Sciences2022，34，5： | 1 |
