| 1 | Evolution of boundary layer ozone in Shijiazhuang,a suburban site on the North China Plain显示文摘The structure of the boundary layer affects the evolution of ozone(O3), and research into this structure will provide important insights for understanding photochemical pollution.In this study, we conducted a one-month observation(from June 15 to July 14, 2016) of the boundary layer meteorological factors as well as O3 and its precursors in Luancheng County,Shijiazhuang(37°53′N, 114°38′E). Our research showed that photochemical pollution in Shijiazhuang is serious, and the mean hourly maximum and mean 8-hr maximum O3 concentrations are 97.9 ± 26.1 and 84.4 ± 22.4 ppbV, respectively. Meteorological factors play a significant role in the formation of O3. High temperatures and southeasterly winds lead to elevated O3 values, and at moderate relative humidity(40%–50%) and medium boundary layer heights(1200–1500 m), O3 production sensitivity occurred in the transitional region between volatile organic compounds(VOC) and nitrogen oxides(NOx) limitations,and the O3 concentration was the highest. The vertical profiles of O3 were also measured by a tethered balloon. The results showed that a large amount of O3 was stored in the residual layer, and the concentration was positively correlated with the O3 concentration measured the previous day. During the daytime of the following day, the contribution of O3 stored in the residual layer to the boundary layer reached 27%± 7% on average. | Wei Zhao Guiqian Tang Huan Yu Yang Yang Yinghong Wang Lili Wang Junlin An Wenkang Gao Bo Hu Mengtian Cheng Xingqin An Xin Li Yuesi Wang | 2019 | Journal of Environmental Sciences2019，31，9： | 15 |
| 2 | Xuebijing injection alleviates liver injury by inhibiting secretory function of Kupffer cells in heat stroke rats显示文摘OBJECTIVE:To evaluate the effects of Xuebijing(XBJ) injection in heat stroke(HS) rats and to investigate the mechanisms underlying these effects.METHODS:Sixty anesthetized rats were randomized into three groups and intravenously injected twice daily for 3 days with 4 mL XBJ(XBJ group) or phosphate buffered saline(HS and Sham groups) per kg body weight.HS was initiated in the HS and XBJ groups by placing rats in a simulated climate chamber(ambient temperature 40 ℃,humidity 60%).Rectal temperature,aterial pressure,and heart rate were monitored and recorded.Time to HS onset and survival were determined,and serum concentrations of tumor necrosis factor(TNF)-α,inRESULTS:Time to HS onset and survival were significantly longer in the XBJ than in the HS group.Moreover,the concentrations of TNF-α,IL-1β,IL-6,ALT and AST were lower and liver injury was milder in the XBJ than in the HS group.Heat-stress induced structural changes in KCs and hepatic cells were more severe in the HS than in the XBJ group and the concentrations of TNF-α,IL-β and IL-6 secreted by KCs were lower in the XBJ than in the HS group.CONCLUSION:XBJ can alleviate HS-induced systemic inflammatory response syndrome and liver injury in rats,and improve outcomes.These protective effects may be due to the ability of XBJ to inhibit cytokine secretion by KCs. | Yi Chen Huasheng Tong Xingqin Zhang Liqun Tang Zhiguo Pan Zhifeng Liu Pengkai Duan Lei Su | 2013 | Journal of Traditional Chinese Medicine2013，33，2： | 14 |
| 3 | Analysis for retrieval and validation results of FY-3 Total Ozone Unit (TOU)显示文摘Retrieval experiment was made for global total column ozone using the first year measurements of Total Ozone Unit (TOU) on board the second generation polar orbiting meteorological satellite of China, FY-3/A. The retrieval results were analyzed and validated by comparison with AURA/OMI, Meteop/GOME-2 global ozone products and ground-based ozone measurement data. The qualititative comparisons over the globe especially over Antarctica and the Tibetan Plateau show that the spatial and temporal distribution characteristics are consistent with OMI and GOME-2 products. The quantitative comparisons with ground-based measurements and AURA/OMI ozone product were made over 74 stations, the TOU total ozone retrieval has a 3% rms relative error compared with AURA/OMI ozone product and 4.2% rms relative error with ground-based measurements. The maximum difference between satellite retrieval and ground-based measurements was found in the Antarctica ozone hole. The TOU global ozone product is operational and distributed to all users. | WANG WeiHe ZHANG XingYing AN XingQin ZHANG Yan HUANG FuXiang WANG YongMei WANG YingJian ZHANG ZhongMou LU JianGong FU LiPing JIANG Fang LIU GuoYang | 2010 | Chinese Science Bulletin2010，55，26： | 12 |

| 5 | Simulation of CO_2 variations at Chinese background atmospheric monitoring stations between 2000 and 2009: Applying a CarbonTracker model显示文摘We carried out a downscaling treatment over China using the CarbonTracker numerical model,which was applied using double grid nesting technology(3°×2°over the whole globe,1°×1°over China),simulating and analyzing atmospheric CO2concentrations over 10 recent years(2000–2009).The simulation results agreed very well with observed data from four background atmospheric monitoring stations in China(The periods for which the simulation results and observed values be compared were January2000 to December 2009 for the WLG station and June 2006 to December 2009 for the SDZ,LFS,and LAN stations),giving correlation coefficients of>0.7.The high-resolution simulation data correlated slightly better than the low resolution simulation data with the observed data for three of the regions’atmospheric background stations.Further analysis of the annual,seasonal CO2concentration variations at the background stations showed that the CO2concentration increased each year over the study period,with an average annual increase of more than 5%,and annual increases of more than 7%at the Shangdianzi and Lin’an stations.Seasonal CO2variations were greater at the Longfengshan station than at the Shangdianzi or Lin’an stations.However,the CO2concentrations were higher at the Shangdianzi and Lin’an stations because they are greatly affected by human activities in the Jingjinji and Changjiang Delta economic zones.Spatial distribution in CO2concentrations and fluxes were higher in eastern than in western China. | CHENG YanLi AN XingQin YUN FangHua ZHOU LingXi LIU LiXin FANG ShuangXi XU Lin | 2013 | Chinese Science Bulletin2013，58，32： | 8 |
| 6 | Simulated Sensitivity of Ozone Generation to Precursors in Beijing during a High O_(3) Episode显示文摘This study uses the WRF-Chem model combined with the empirical kinetic modeling method(EKMA curve)to study the compound pollution event in Beijing that happened in 13−23 May 2017.Sensitivity tests are conducted to analyze ozone sensitivity to its precursors,and to develop emission reduction measures.The results suggest that the model can accurately simulate the compound pollution process of photochemistry and haze.When VOCs and NOx were reduced by the same proportion,the effect of O_(3)reduction at peak time was more obvious,and the effect during daytime was more significant than at night.The degree of change in ozone was peak time>daytime average.When reducing or increasing the ratio of precursors by 25%at the same time,the effect of reducing 25%VOCs on the average ozone concentration reduction was most significant.The degree of change in ozone decreased with increasing altitude,the location of the ozone maximum change shifted westward,and its range narrowed.As the altitude increases,the VOCs-limited zone decreases,VOCs sensitivity decreases,NOx sensitivity increases.The controlled area changed from near-surface VOCs-limited to high-altitude NOx-limited.Upon examining the EKMA curve,we have found that suburban and urban are sensitive to VOCs.The sensitivity tests indicate that when VOCs in suburban are reduced about 60%,the O_(3)-1h concentration could reach the standard,and when VOCs of the urban decreased by about 50%,the O_(3)-1h concentration could reach the standard.Thus,these findings could provide references for the control of compound air pollution in Beijing. | Meng CUI Xingqin AN Li XING Guohui LI Guiqian TANG Jianjun HE Xin LONG Shuman ZHAO | 2021 | Advances in Atmospheric Sciences2021，38，7： | 7 |
| 7 | Estimating emissions of HCFC-22 and CFC-11 in China by atmospheric observations and inverse modeling显示文摘This paper presents the estimation of Chinese emissions of HCFC-22 and CFC-11 in 2009 by an inverse modeling method based on in-situ measurement data from the Shangdianzi Global Atmosphere Watch (GAW) Regional Station (SDZ) and atmospheric transport simulations. After inversion (a-posteriori) estimates of the Chinese emissions in 2009 increased by 6.6% for HCFC-22 from 91.7 (± 83.6) to 98.3 (± 47.4) kt/yr and by 22.5% for CFC-11 from 13 (±12.6) to 15.8 (±7.2) kt/yr compared to an a-priori emission. While the model simulation with a-priori emissions already captured the main features of the observed variability at the measurement site, the model performance (in terms of correlation and mean-square-error) improved using a-posteriori emissions. The inversion reduced the root-mean-square (RMS) error by 4% and 10% for HCFC-22 and CFC-11, respectively. | AN XingQin HENNE Stephan YAO Bo VOLLMER Martin K.

| 8 | Emission inventory evaluation using observations of regional atmospheric background stations of China显示文摘Any accurate simulation of regional air quality by numerical models entails accurate and up-to-date emissions data for that region.The INTEX-B2006 (I06),one of the newest emission inventories recently popularly used in China and East Asia,has been assessed using the Community Multiscale Air Quality model and observations from regional atmospheric background stations of China.Comparisons of the model results with the observations for the species SO2,NO 2,O 3 and CO from the three regional atmospheric background stations of Shangdianzi,Longfengshan and Linan show that the model can basically capture the temporal characteristics of observations such as the monthly,seasonal and diurnal variance trends.Compared to the other three species,the simulated CO values were grossly underestimated by about two-third or one-half of the observed values,related to the uncertainty in CO emissions.Compared to the other two stations,Shangdianzi had poorer simulations,especially for SO2 and CO,which partly resulted from the site location close to local emission sources from the Beijing area;and the regional inventory used was not capable of capturing the influencing factors of strong regional sources on stations.Generally,the fact that summer gave poor simulation,especially for SO2 and O 3,might partly relate to poor simulations of meteorological fields such as temperature and wind. | Xingqin An Zhaobin Sun Weili Lin Min Jin Nan Li | 2013 | Journal of Environmental Sciences2013，25，3： | 7 |
| 9 | Curative effect of Xuebijing injection on severe pulmonary contusion显示文摘OBJECTIVE: To investigate the curative effects of Xuebijing(XBJ) injection, a Chinese patent medicine, on severe pulmonary contusion(PC). METHODS: Sixty-three patients with PC were randomized to conventional therapy plus XBJ injection(n=33) or conventional therapy alone(n=30). Between groups differences in corticosteroid treatment, immune regulation therapy, hemofiltration, infusion volume, transfusion volume and antibiotic period were measured, as were intensive care unit (ICU)-free time, ventilation time, 28-day mortality rate and incidence of ventilation-associated pneumonia(VAP). Serum concentrations of procalcitonin(PCT), tumor necrosis factor-α(TNF-α), interleukin(IL)-6, and IL-10, white blood cell(WBC) counts and percentages of human leukocyte antigen DR/ CD14+(HLA-DR/CD14+) peripheral blood mononuclear cells were compared. Markers of ventilation were determined by blood gas analysis and ventilator parameters. RESULTS: WBC counts and serum concentrations of PCT, TNF-α, IL-6 and IL-10 were reduced significantly more quickly, and CD14+ percentage was increased significantly earlier, in the XBJ group than in the control group(P<0.05 each).The level of ventilation and oxygenation index were ameliorated earlier in the XBJ than in the control group(P< 0.05). XBJ treatment significantly reduced ICU-stay time, ventilation time and incidence of VAP(P<0.05 each), but had no effect on 28-day mortality rate(P>0.05). CONCLUSION: XBJ treatment can shorten ICU-free and ventilation times and reduce the incidence of VAP, improving outcomes in patients with severe PC. XBJ may act by regulating inflammation and immunity, alleviating systemic inflammatory response syndrome induced by trauma. | Yi Chen Huasheng Tong Wang Zhang Xingqin Zhang Zhigguo Pan Junming Qiu Ruihuan Pan Lei Su | 2013 | Journal of Traditional Chinese Medicine2013，33，6： | 6 |

| 11 | Chaperone-mediated autophagy and neurodegeneration:connections,mechanisms,and therapeutic implications显示文摘Lysosomes degrade dysfunctional intracellular components via three pathways: macroautophagy, microautophagy, and chaperone-mediated autophagy(CMA). Unlike the other two, CMA degrades cytosolic proteins with a recognized KFERQ-like motif in lysosomes and is important for cellular homeostasis. CMA activity declines with age and is altered in neurodegenerative diseases. Its impairment leads to the accumulation of aggregated proteins, some of which may be directly tied to the pathogenic processes of neurodegenerative diseases. Its induction may accelerate the clearance of pathogenic proteins and promote cell survival, representing a potential therapeutic approach for the treatment of neurodegenerative diseases. In this review, we summarize the current findings on how CMA is involved in neurodegenerative diseases, especially in Parkinson's disease. | Xiaolei Liu Sihua Huang Xingqin Wang Beisha Tang Wenming Li Zixu Mao | 2015 | Neuroscience Bulletin2015，31，4： | 4 |
| 12 | Ceramic membrane separation technique for washing nano-sized ceramic powder precursors显示文摘Washing using ceramic micro-filtration membranes was studied in the preparation of nano-sized TiO2 and Al2O3 powder precursors obtained by wet chemical methods. The key parameters for the washing process, such as operation pressure, cross-flow velocity, and slurry concentration, were examined and optimized. The shape and size of particles influenced the structure of the filter cake, leading to different permeation flux for different systems. The results demonstrated that washing using ceramic membranes is superior to the traditional plate-and-frame filtration and could be considered an advanced technique for ultra-fine powder preparation by wet-chemical method. | Qiang Dong Xingqin Liu Tianshu Zhang | 2011 | Particuology2011，9，5： | 3 |
| 13 | Temporal Variation and Source Identification of Black Carbon at Lin'an and Longfengshan Regional Background Stations in China显示文摘Black carbon(BC) is a component of fine particulate matter(PM_(2.5)), associated with climate, weather, air quality,and people's health. However, studies on temporal variation of atmospheric BC concentration at background stations in China and its source area identification are lacking. In this paper, we use 2-yr BC observations from two background stations, Lin'an(LAN) and Longfengshan(LFS), to perform the investigation. The results show that the mean diurnal variation of BC has two significant peaks at LAN while different characteristics are found in the BC variation at LFS, which are probably caused by the difference in emission source contributions. Seasonal variation of monthly BC shows double peaks at LAN but a single peak at LFS. The annual mean concentrations of BC at LAN and LFS decrease by 1.63 and 0.26 μg m–3 from 2009 to 2010, respectively. The annual background concentration of BC at LAN is twice higher than that at LFS. The major source of the LAN BC is industrial emission while the source of the LFS BC is residential emission. Based on transport climatology on a 7-day timescale, LAN and LFS stations are sensitive to surface emissions respectively in belt or approximately circular area, which are dominated by summer monsoon or colder land air flows in Northwest China. In addition, we statistically analyze the BC source regions by using BC observation and FLEXible PARTicle dispersion model(FLEXPART) simulation. In summer, the source regions of BC are distributed in the northwest and south of LAN and the southwest of LFS. Low BC concentration is closely related to air mass from the sea. In winter, the source regions of BC are concentrated in the west and south of LAN and the northeast of the threshold area of stot at LFS. The cold air mass in the northwest plays an important role in the purification of atmospheric BC. On a yearly scale, sources of BC are approximately from five provinces in the northwest/southeast of LAN and the west of LFS. These findings are helpful in reducing BC emission and controlling air pollution. | Siyang CHENG Yaqiang WANG Xingqin AN | 2017 | Journal of Meteorological Research2017，31，6： | 2 |
