| 4 | The roles of heterogeneous chemical processes in the formation of an air pollution complex and gray haze显示文摘Urban and regional air pollutions are characterized by high concentrations of secondary pollutants such as photo-oxidants (mainly ozone) and fine particulate matter,which are formed through chemical reactions of the primary pollutants emitted from various sources.The accumulation of these pollutants under stagnant meteorological conditions results in the formation of gray haze,reducing visibility and causing major impacts on human health and climate.In an air pollution complex,the coexistence of high concentrations of primary and secondary gaseous and particulate pollutants provides a large amount of reactants for heterogeneous reactions on the surface of fine particles;these reactions change the oxidizing capacity of the atmosphere,as well as chemical compositions along with the physicochemical and optical properties of particulate matter,thereby accelerating formation of the air pollution complex and gray haze.Using in situ technologies,such as diffuse reflectance infrared Fourier-transform spectroscopy and single-particle Raman spectroscopy,we systematically investigated the reaction kinetics and mechanisms of gaseous pollutants (i.e.,NO2,SO2,O3,and formaldehyde) on the surfaces of the major components of atmospheric particles such as CaCO3,kaolinite,montmorillonite,NaCl,sea salt,Al2O3,and TiO2.We found that the main reaction products were sulfate,nitrate,or formate,which can change the hygroscopicity and light extinction parameters of those particles significantly.By analyzing the reaction kinetics of these heterogeneous reactions,we identified synergetic mechanisms of the three ternary reaction systems,i.e.,NO2-particlesH2O,SO2-particles-O3,and organics/SO2-particles–UV illumination.These synergetic mechanisms can provide experimental and theoretical bases for understanding the feedback mechanisms and nonlinear processes in the formation of an air pollution complex and gray haze. | ZHU Tong,SHANG Jing & ZHAO DeFeng State Key Joint Laboratory of Environmental Simulation and Pollution Control College of Environmental Sciences and Engineering,Peking University,Beijing 100871,China | 2011 | Science China Chemistry2011,54,1: | 24 |
| 5 | Lithofacies palaeogeography of the Carboniferous and Permian in the Qinshui Basin, Shanxi Province, China显示文摘The Qinshui Basin in the southeastern Shanxi Province is an important area for coalbed methane(CBM) exploration and production in China, and recent exploration has revealed the presence of other unconventional types of gas such as shale gas and tight sandstone gas. The reservoirs for these unconventional types of gas in this basin are mainly the coals, mudstones, and sandstones of the Carboniferous and Permian; the reservoir thicknesses are controlled by the depositional environments and palaeogeography. This paper presents the results of sedimentological investigations based on data from outcrop and borehole sections, and basin-wide palaeogeographical maps of each formation were reconstructed on the basis of the contours of a variety of lithological parameters. The palaeogeographic units include the depositional environments of the fluvial channel, flood basin(lake), upper delta plain, lower delta plain, delta front, lagoon, tidal flat, barrier bar, and carbonate platform.The Benxi and Taiyuan Formations are composed mainly of limestones, bauxitic mudstones,siltstones, silty mudstones, sandstones, and economically exploitable coal seams, which were formed in delta, tidal flat, lagoon, and carbonate platform environments. The Shanxi Formation consists of sandstones, siltstones, mudstones, and coals; during the deposition of the formation, the northern part of the Qinshui Basin was occupied mainly by an upper delta plain environment, while the central and southern parts were mainly occupied by a lower delta plain environment and the southeastern part by a delta front environment. Thick coal zones occur in the central and southern parts, where the main depositional environment was a lower delta plain. The thick coal zones of the Taiyuan Formation evidently occur in the sandstone-rich belts, located mainly in the lower delta plain environment in the northern part of the basin and the barrier bar environments in the southeastern part of the basin. In contrast, the thick coal zones of the Shanxi Formation extend over the mudstone-rich belts, located in the areas of the lower delta plain environments of the central and southern parts of the Basin.The Xiashihezi, Shangshihezi, and Shiqianfeng Formations consist mainly of red mudstones with thick-interbedded sandstones. During the deposition of these formations, most areas of the basin were occupied by a fluvial channel, resulting in palaeogeographic units that include fluvial channel zones and flood basins. The fluvial channel deposits consist mainly of relatively-thick sandstones, which could have potential for exploration of tight sandstone gas. | Long-Yi Shao Zhi-Yu Yang Xiao-Xu Shang Zheng-Hui Xiao Shuai Wang Wen-Long Zhang Ming-Quan Zheng Jing Lu | 2015 | Journal of Palaeogeography2015,4,4: | 21 |
| 6 | Association between Ambient Air Pollution and Hospital Emergency Admissions for Respiratory and Cardiovascular Diseases in Beijing: a Time Series Study显示文摘Objective To investigate the association between ambient air pollution and hospital emergency admissions in Beijing. Methods In this study, a semi-parametric generalized additive model(GAM) was used to evaluate the specific influences of air pollutants(PM10, SO2, and NO2) on hospital emergency admissions with different lag structures from 2009 to 2011, the sex and age specific influences of air pollution and the modifying effect of seasons on air pollution to analyze the possible interaction. Results It was found that a 10 μg/m3 increase in concentration of PM10 at lag 03 day, SO2 and NO2 at lag 0 day were associated with an increase of 0.88%, 0.76%, and 1.82% respectively in overall emergency admissions. A 10 μg/m3 increase in concentration of PM10, SO2 and NO2 at lag 5 day were associated with an increase of 1.39%, 1.56%, and 1.18% respectively in cardiovascular disease emergency admissions. For lag 02, a 10 μg/m3 increase in concentration of PM10, SO2 and NO2 were associated with 1.72%, 1.34%, and 2.57% increases respectively in respiratory disease emergency admissions. Conclusion This study further confirmed that short-term exposure to ambient air pollution was associated with increased risk of hospital emergency admissions in Beijing. | ZHANG Ying WANG Shi Gong MA Yu Xia SHANG Ke Zheng CHENG Yi Fan LI Xu NING Gui Cai ZHAO Wen Jing LI Nai Rong | 2015 | Biomedical and Environmental Sciences2015,28,5: | 18 |

| 9 | Grape Seed Proanthocyanidin Extract Alleviates Arsenic-induced Oxidative Reproductive Toxicity in Male Mice显示文摘Objective To determine the ability of grape seed proanthocyanidin extract(GSPE) in alleviating arsenic-induced reproductive toxicity. Methods Sixty male Kunming mice received the following treatments by gavage: normal saline solution(control); arsenic trioxide(ATO; 4 mg/kg); GSPE(400 mg/kg); ATO+GSPE(100 mg/kg); ATO+GSPE(200 mg/kg) and ATO+GSPE(400 mg/kg). Thereafter, the mice were sacrificed and weighed, and the testis was examined for pathological changes. Nuclear factor(erythroid-derived 2)-like 2(Nrf2), heme oxygenase 1(HO1), glutathione S-transferase(GST), NAD(P)H dehydrogenase, and quinone 1(NQO1) expression in the testis was detected by real-time PCR. Superoxide dismutase(SOD), glutathione(GSH), total antioxidative capability(T-AOC), malondialdehyde(MDA), 8-hydroxydeoxyguanosine(8-OHd G), and reproductive indexes were analyzed. Results ATO-treated mice showed a significantly decreased sperm count and testis somatic index and activity levels of SOD, GSH, and T-AOC than control group. Compared to the ATO-treated group, ATO +GSPE group showed recovery of the measured parameters. Mice treated with ATO+high-dose GSPE showed the highest level of m RNA expression of Nrf2, HO, NQO1, and GST. Conclusion GSPE alleviates oxidative stress damage in mouse testis by activating Nrf2 signaling, thus counteracting arsenic-induced reproductive toxicity. | LI Shu Gang DING Yu Song NIU Qiang XU Shang Zhi PANG Li Juan MA Ru Lin JING Ming Xia FENG Gang Ling LIU Jia Ming GUO Shu Xia | 2015 | Biomedical and Environmental Sciences2015,28,4: | 14 |

| 11 | Association between serum estradiol level on the human chorionic gonadotrophin administration day and clinical outcome显示文摘Background: Estradiol, as an important hormone in follicular development and endometrial receptivity, is closely related to clinical outcomes of fresh in vitro fertilization embryo transfer (IVF-ET) cycles. The aim of this retrospective study was to evaluate the association between elevated serum estradiol (E2) levels on the day of human chorionic gonadotrophin (hCG) administration and IVF-ET pregnancy and birth outcomes. Methods: A total of 1771 infertile patients with their first fresh IVF-ET cycles were analyzed retrospectively between January 2011 and January 2016 in Peking University First Hospital. Patients were categorized by serum E2 levels on the day of hCG administration into six groups: group 1 (serum E2 levels < 1000 pg/mL, n = 205), group 2 (serum E2 levels 1001-2000 pg/mL, n = 457), group 3 (serum E2 levels 2001-3000 pg/mL, n = 425), group 4 (serum E2 levels 3001-4000 pg/mL, n = 310), group 5 (serum E2 levels 4001- 5000 pg/mL, n = 237), and group 6 (serum E2 levels > 5000 pg/mL, n — 137). The retrieved oocyte and Mil oocyte numbers and implantation and clinical pregnancy rates of the groups were compared as the first objective of the study. For the 360 women with singleton births among all patients, the area under the corresponding receiver operating characteristic curve (ROC curve) was calculated to assess the predictive value of the E2 change for the probability of low birth weight (LBW) infants as the second objective. Results: The retrieved oocyte and Mil oocyte numbers and implantation and clinical pregnancy rates gradually increased from groups 1 to 5 but decreased in group 6. The parameters of group 1 were statistically worse than those of the other groups, from group 2 to group 6 (the number of retrieved oocytes, t = 13.096, t = 23.307, t = 23.086, t = 26.376, t = 19.636, P < 0.003;the number of retrieved Mil oocytes, t = 10.856, t = 20.868, t = 21.874, t = 23.374, t = 19.092, P < 0.003;the implantation rate,χ^2= 12.179,χ^2= 22.239,χ^2= 23.993,χ^2= 23.344,χ^2= 16.758, P < 0.003;the clinical pregnancy rate,χ^2= 16.415,χ^2= 28.074,χ^2= 35.387,χ^2= 37.025,χ^2= 24.590, P < 0.003). ROC analysis revealed that when a serum peak E2 of 3148 pg/mL was used to predict LBW. Conclusions: The results indicate that serum E2 levels have a concentration-dependent effect on clinical outcomes. The optimal range of the E2 level during a fresh IVF-ET cycle is 1000 to 3148 pg/mL. | Xin Li Cheng Zeng Jing Shang Sheng Wang Xue-Lian Gao Qing Xue | 2019 | Chinese Medical Journal2019,,10: | 12 |
| 12 | Traditional Chinese medicine network pharmacology study on exploring the mechanism of Xuebijing Injection in the treatment of coronavirus disease 2019显示文摘As a representative drug for the treatment of severe community-acquired pneumonia and sepsis,Xuebijing(XBJ)injection is also one of the recommended drugs for the prevention and treatment of coronavirus disease 2019(COVID-19),but its treatment mechanism for COVID-19 is still unclear.Therefore,this study aims to explore the potential mechanism of XBJ injection in the treatment of COVID-19 employing network pharmacology and molecular docking methods.The corresponding target genes of 45 main active ingredients in XBJ injection and COVID-19 were obtained by using multiple database retrieval and literature mining.102 overlapping targets of them were screened as the core targets for analysis.Then built the PPI network,TCM-compound-target-disease,and disease-target-pathway networks with the help of Cytoscape 3.6.1 software.After that,utilized DAVID to perform gene ontology(GO)function enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis to predict the action mechanism of overlapping targets.Finally,by applying molecular docking technology,all compounds were docked with COVID-193 CL protease(3 CLpro),spike protein(S protein),and angiotensin-converting enzyme II(ACE2).The results indicated that quercetin,luteolin,apigenin and other compounds in XBJ injection could affect TNF,MAPK1,IL6 and other overlapping targets.Meanwhile,anhydrosafflor yellow B(AHSYB),salvianolic acid B(SAB),and rutin could combine with COVID-19 crucial proteins,and then played the role of anti-inflammatory,antiviral and immune response to treat COVID-19.This study revealed the multiple active components,multiple targets,and multiple pathways of XBJ injection in the treatment of COVID-19,which provided a new perspective for the study of the mechanism of traditional Chinese medicine(TCM)in the treatment of COVID-19. | XING Yan HUA Ying-Rong SHANG Jing GE Wei-Hong LIAO Jun | 2020 | Chinese Journal of Natural Medicines2020,18,12: | 11 |
| 13 | Review of the fabrication and application of porous materials from silicon-rich industrial solid waste显示文摘Porous materials have promise as sound insulation, heat barrier, vibration attenuation, and catalysts. Most industrial solid wastes, such as tailings, coal gangue, and fly ash are rich in silicon. Additionally, a high silicon content waste is a potential raw material for the syn- thesis of silicon-based, multi-porous materials such as zeolites, mesoporous silica, glass-ceramics, and geopolymer foams. Representative sil- icon-rich industrial solid wastes (SRISWs) are the focus of this mini review of the processing and application of porous silicon materials with respect to the physical and chemical properties of the SRISW. The transformation methods of preparing porous materials from SRISWs are summarized, and their research status in micro-, meso-, and macro-scale porous materials are described. Possible problems in the application of SRISWs and in the preparation of functional porous materials are analyzed, and their development prospects are discussed. This review should provide a typical reference for the recycling and use of industrial solid wastes to develop sustainable “green materials.” | Chao Miao Lixing Liang Fan Zhang Shumei Chen Kaixuan Shang Jinlong Jiang Yi Zhang Jing Ouyang | 2022 | International Journal of Minerals,Metallurgy and Materials2022,29,3: | 10 |

| 19 | Heterogeneous reaction of SO_2 on TiO_2 particles显示文摘The heterogeneous reaction of SO2 on TiO2 particles was studied using in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS).The influences of the oxygen concentration,relative humidity (RH),and ultraviolet (UV) light illumination (λ=365 nm) intensity on the reaction were investigated.The main product of the heterogeneous reaction of SO2 on TiO2 particles was sulfate with UV illumination and sulfite without it.The production of sulfate was promoted significantly with UV illumination or water,and there was a synergistic effect when both were present.In the dry system without UV,the heterogeneous reaction of SO2 on TiO2 particles was found to be second-order for SO2 and the initial uptake coefficient,BET,was determined to be 1.94 × 10-6.With UV and RH=40%,the reaction order was first-order and the initial uptake coefficient was 1.35 × 10-5. | SHANG Jing,LI Jia & ZHU Tong State Key Joint Laboratory of Environmental Simulation and Pollution Control College of Environmental Sciences and Engineering,Peking University,Beijing 100871,China | 2010 | Science China Chemistry2010,53,12: | 8 |
| 20 | Activation and coreceptor expression of T lymphocytes induced by highly active antiretroviral therapy in Chinese HIV/AIDS patients显示文摘Background At the end of 2005, 650 000 people lived with human immunodeficiency virus type-1 (HIV-1) in China, of whom 75 000 were AIDS patients. Many AIDS patients received highly active antiretroviral therapy (HAART) supported by the “China CARES” program but the immune responses of HAART were seldom reported. This study investigated the effect of HAART on the activation and coreceptor expression of T lymphocytes in Chinese HIV/AIDS patients and evaluated its effect on immune reconstitution. Methods Seventeen HIV/AIDS patients were enrolled and three-color-flow cytometry was used to detect the activation of HLA-DR CD38 and the coreceptor CCR5, CXCR4 expression on T lymphocytes in whole blood samples taken from the patients before and after 3- or 6-month HAART. Results The activation percents of CD4+, CD8+ T lymphocytes were significantly higher before therapy than the normal controls (HLA-DR/CD4: 40.47±18.85 vs 11.54±4.10; CD38/CD4: 81.34±10.86 vs 53.34±11.44; HLA-DR/CD8: 63.94±12.71 vs 25.67±9.18; CD38/CD8: 86.56±11.41 vs 58.84±6.16, all P<0.01). After 6-month combined antiretroviral treatment, the activation of T lymphocytes in HIV/AIDS patients was significantly decreased (HLA-DR/CD4: 28.31±13.48; CD38/CD4: 69.88±12.64; HLA-DR/CD8: 46.56±18.64; CD38/CD8: 70.17±14.54, all P<0.01 compared with the pre-treatment values). Before the treatment, CCR5 expression on CD8+ T lymphocytes was up-regulated while CXCR4 expression on CD8+ T lymphocytes downregulated in HIV/AIDS patients compared with the normal controls (CD8/CCR5: 70.91±10.03 vs 52.70± 7.68; CD8/CXCR4: 24.14±11.08 vs 50.05±11.68, all P<0.01). After 6-month HAART, CCR5 expression on CD8+ T lymphocytes significantly decreased (56.35±12.96, P<0.01), while CXCR4 expression on CD8+ T lymphocytes increased (36.95±9.96, P<0.05) compared with the pre-treatment and the normal controls. A significant statistical relationship was observed between the expression of activation markers, CCR5 and the CD4+ T lymphocyte counts after HAART (P<0.05). Conclusions Reduced activation of T lymphocytes and a normalization of coreceptor expression were observed in Chinese HIV/AIDS patients after HAART. Immunity can be restored in HIV/AIDS patients receiving HAART. | ZHANG Zi-ning SHANG Hong JIANG Yong-jun LIU Jing DAI Di DIAO Ying-ying GENG Wen-qing JIN Xin WANG Ya-nan | 2006 | Chinese Medical Journal2006,,23: | 8 |
