| 2 | Mapping wetland changes in China between 1978 and 2008显示文摘Four wetland maps for all China have been produced,based on Landsat and CBERS-02B remote sensing data between 1978 and 2008 (1978,1990,2000 and 2008).These maps were mainly developed by manual interpretation and validated by substantial field investigation in 2009.Based on these maps,we analyzed the 2008 wetland distribution in China and discussed wetland changes and their drivers over the past 30 years.(i) There were about 324097 km 2 of wetlands in 2008,for which inland marshes or swamps were the most common wetland type (35%),with lakes (26%) second.Most of the wetlands were in Heilongjiang,Inner Mongolia,Qinghai and Tibet,occupying about 55% of the national wetland area.(ii) From 1978 to 2008,China's wetland area continually and significantly decreased,by about 33% based on changes in the wetland map.This was in sharp contrast to the increase in artificial wetlands,which increased by about 122%.Inland marshes accounted for the main loss of total wetlands from 1978 to 2000.From 2000 through 2008,riverine and lacustrine wetlands constituted the main wetland loss.Fortunately however,the rate of wetland loss decreased from 5523 to 831 km 2 /a.(iii) The change ratio of lost natural wetlands (including inland and coastal wetlands) to non-wetlands has decreased slightly over the past 30 years.From 1978 to 1990,nearly all natural wetlands (98%) lost were transformed into non-wetlands.However,the ratio declined to 86% from 1990 to 2000,and to 77% from 2000 to 2008.(iv) All Chinese provinces were divided into three groups according to patterns of wetland changes,which could relate to the driving forces of such changes.Tibet was completely different from other provinces,as it was one representative example in which there was a net wetland increase,because of global warming and decreased human activity since 1990.Increased economic development caused considerable wetland loss in most eastern provinces,and artificial wetlands increased. | NIU ZhenGuo ZHANG HaiYing WANG XianWei YAO WenBo ZHOU DeMin ZHAO KuiYi ZHAO Hui LI NaNa HUANG HuaBing LI CongCong YANG Jun LIU CaiXia LIU Shuang WANG Lin LI Zhan YANG ZhenZhong QIAO Fei ZHENG YaoMin CHEN YanLei SHENG YongWei GAO XiaoHong ZHU WeiHong WANG WenQing WANG Hong WENG YongLing ZHUANG DaFang LIU JiYuan LUO ZhiCai CHENG Xiao GUO ZiQi GONG Peng | 2012 | Chinese Science Bulletin2012,57,22: | 51 |

| 5 | 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 |

| 8 | High mobility group box-1 protein inhibits regulatory T cell immune activity in liver failure in patients with chronic hepatitis B显示文摘BACKGROUND:Liver failure in chronic hepatitis B(CHB) patients is a severe,life-threatening condition.Intestinal endotoxemia plays a significant role in the progress to liver failure.High mobility group box-1(HMGB1) protein is involved in the process of endotoxemia.Regulatory T(Treg) cells maintain immune tolerance and contribute to the immunological hyporesponsiveness against HBV infection.However,the roles of HMGB1 and Treg cells in the pathogenesis of liver failure in CHB patients,and whether HMGB1 affects the immune activity of Treg cells are poorly known at present,and so were explored in this study.METHODS:The levels of HMGB1 expression were detected by ELISA,real-time RT-PCR,and Western blotting,and the percentage of CD4+CD25+CD127low Treg cells among CD4+ cells was detected by flow cytometry in liver failure patients with chronic HBV infection,CHB patients,and healthy controls.Then,CD4+CD25+CD127low Treg cells isolated from the peripheral blood mononuclear cells from CHB patients were stimulated with HMGB1 at different concentrations or at various intervals.The effect of HMGB1 on the immune activity of Treg cells was assessed by a suppression assay of the allogeneic mixed lymphocyte response.The levels of forkhead box P3(Foxp3) expression in Treg cells treated with HMGB1 were detected by RT-PCR and Western blotting.RESULTS:A higher level of HMGB1 expression and a lower percentage of Treg cells within the population of CD4+ cells were found in liver failure patients than in CHB patients(82.6±20.1 μg/L vs.34.2±13.7 μg/L;4.55±1.34% vs.9.52± 3.89%,respectively).The immune activity of Treg cells was significantly weakened and the levels of Foxp3 expression were reduced in a dose-or time-dependent manner when Treg cells were stimulated with HMGB1 in vitro.CONCLUSIONS:The high level of HMGB1 and the low percentage of Treg cells play an important role in the pathogenesis of liver failure in patients with chronic HBV infection.Moreover,HMGB1 can weaken the immune activity of Treg cells.It is suggested that effectively inhibiting HMGB1 expression could be a feasible way to treat liver failure by suppressing endotoxemia and enhancing Treg cell activity. | Wang, Lu-Wen Chen, Hui Gong, Zuo-Jiong | 2010 | Hepatobiliary & Pancreatic Diseases International2010,9,5: | 23 |
| 9 | Time-dependent categorization of volatile aroma compound formation in stewed Chinese spicy beef using electron nose profile coupled with thermal desorption GC–MS detection显示文摘In the present study,flavor profiles of Chinese spiced beef in the cooking process were comparatively analyzed by electronic nose,gas chromatography–mass spectrometry(GC–MS)with a thermal desorption system(TDS),and solid-phase microextraction(SPME).A total of 82 volatile compounds were identified,and 3-methyl-butanal,pentanal,hexanal,-xylene,heptanal,limonene,terpinene,octanal,linalool,4-terpinenol,-terpineol,and(E)-anethole were identified as the characteristic flavor compounds in Chinese spiced beef.Variation in the content of volatile components produced by different cooking processes was observed.In general,a cooking time of 4 h resulted in optimal flavor quality and stability.Results indicated that the electronic nose could profile and rapidly distinguish variation among different cooking time.The volatile profiling by TDS-GC–MS and responses from the electronic nose,in combination with multivariate statistical analysis,are a promising tool for control the cooking process of spiced beef. | Hui Gong Zhen Yang Meng Liu Zhijia Shi Jiapeng Li Wenhua Chen Xiaoling Qiao | 2017 | Food Science and Human Wellness2017,6,3: | 21 |

| 13 | Municipal wastewater treatment in China:Development history and future perspectives显示文摘China has the world's largest and still growing wastewater sector and water market,thus its future development will have profound influence on the world.The high-speed development of China's wastewater sector over the past 40 years has forged its global leading treatment capacity and innovation ability.However,many problems were left behind,including underdeveloped sewers and sludge disposal facilities,low sustainability of the treatment processes,questionable wastewater treatment plant(WWTP)effluent discharge standards,and lacking global thinking on harmonious development between wastewater management,human society and the nature.Addressing these challenges calls for fundamental changes in target design,policy and technologies.In this mini-review,we revisit the development history of China's municipal wastewater management and identify the remaining challenges.Also,we highlight the future needs of sustainable development and exploring China's own wastewater management path,and outlook the future from several aspects including targets of wastewater management,policies and technologies,especially the new concept WWTP.Furthermore,we envisage the establishment of new-generation WWTPs with the vision of turning WWTP from a site of pollutant removal into a plant of energy,water and fertilizer recovery and an integrated part urban ecology in China. | Jiuhui Qu Hongchen Wang Kaijun Wang Gang Yu Bing Ke Han-Qing Yu Hongqiang Ren Xingcan Zheng Ji Li Wen-Wei Li Song Gao Hui Gong | 2019 | Frontiers of Environmental Science & Engineering2019,13,6: | 13 |
| 14 | Cold-Induced CBF–PIF3 Interaction Enhances Freezing Tolerance by Stabilizing the phyB Thermosensor in Arabidopsis显示文摘Growth inhibition and cold-acclimation strategies help plants withstand cold stress,which adversely affects growth and survival.PHYTOCHROME B(phyB)regulates plant growth through perceiving both light and ambient temperature signals.However,the mechanism by which phyB mediates the plant response to cold stress remains elusive.Here,we show that the key transcription factors mediating cold acclimation,C-REPEAT BINDING FACTORs(CBFs),interact with PHYTOCHROME-INTERACTING FACTOR 3(PIF3)under cold stress,thus attenuating the mutually assured destruction of PIF3–phyB.Cold-stabilized phyB acts downstream of CBFs to positively regulate freezing tolerance by modulating the expression of stress-responsive and growth-related genes.Consistent with this,phyB mutants exhibited a freezing-sensitive phenotype,whereas phyB-overexpression transgenic plants displayed enhanced freezing tolerance.Further analysis showed that the PIF1,PIF4,and PIF5 proteins,all of which negatively regulate plant freezing tolerance,were destabilized by cold stress in a phytochrome-dependent manner.Collectively,our study reveals that CBFs–PIF3–phyB serves as an important regulatory module for modulating plant response to cold stress. | Bochen Jiang Yiting Shi Yue Peng Yuxin Jia Yan Yan Xiaojing Dong Hui Li Jie Dong Jigang Li Zhizhong Gong Michael F.Thomashow Shuhua Yang | 2020 | Molecular Plant2020,13,6: | 13 |
| 15 | Fatty Acid Synthase and Hormone-sensitive Lipase Expression in Liver Are Involved in Zinc-α2-glycoprotein-induced Body Fat Loss in Obese Mice显示文摘Objective To explore the effects of zinc-α2-glycoprotein(ZAG) on body weight and body fat in high-fat-diet(HFD)-induced obesity in mice and the possible mechanism.Methods Thirty-six male mice were fed with standard food(SF)(n=9) and HFD(n=27),respectively.Five weeks later,9 mice fed with HFD were subjected to ZAG expression plasmid DNA transfection by liposome transfection method,and another 9 mice to negative control plasmid transfection.Two weeks later,serum ZAG level in the mice was assayed by Western blot,and the effects of ZAG over-expression on body weight,body fat,serum biochemical indexes,and adipose tissue of obese mice were evaluated.The mRNA expressions of fatty acid synthase(FAS) and hormone-sensitive lipase(HSL) in liver tissue were determined by reverse transcription-polymerase chain reaction.Results Serum ZAG level significantly lowered in simple HFD-fed mice in comparison to SF-fed mice(0.51±0.10 AU vs.0.75±0.07 AU,P<0.01).Further statistical analysis demonstrated that ZAG level was negatively correlated with body weight(r =-0.56,P<0.001),epididymal fat mass(r=-0.67,P<0.001),percentage of epididymal fat(r=-0.65,P<0.001),and increased weight(r=-0.57,P<0.001) in simple SF-and HFD-fed mice.ZAG over-expression in obese mice reduced body weight and the percentage of epididymal fat.Furthermore,FAS mRNA expression decreased(P<0.01) and HSL mRNA expression increased(P<0.001) in the liver in ZAG over-expressing mice.Conclusions ZAG is closely related to obesity.Serum ZAG level is inversely correlated with body weight and percentage of body fat.The action of ZAG is associated with reduced FAS expression and increased HSL expression in the liver of obese mice. | Feng-ying Gong Jie-ying Deng Hui-juan Zhu Hui Pan Lin-jie Wang Hong-bo Yang | 2010 | Chinese Medical Sciences Journal2010,25,3: | 12 |

| 17 | New role for ceramide in hypoxia and insulin resistance显示文摘Ceramides are significant metabolic products of sphingolipids in lipid metabolism and are associated with insulin resistance and hepatic steatosis. In chronic inflammatory pathological conditions, hypoxia occurs, the metabolism of ceramide changes, and insulin resistance arises. Hypoxia-inducible factors(HIFs)are a family of transcription factors activated by hypoxia. In hypoxic adipocytes,HIF-1α upregulates pla2 g16(a novel HIF-1α target gene) gene expression to activate the NLRP3 inflammasome pathway and stimulate insulin resistance, and adipocyte-specific Hif1 a knockout can ameliorate homocysteine-induced insulin resistance in mice. The study on the HIF-2α-NEU3-ceramide pathway also reveals the role of ceramide in hypoxia and insulin resistance in obese mice.Under obesity-induced intestinal hypoxia, HIF-2α increases the production of ceramide by promoting the expression of the gene Neu3 encoding sialidase 3,which is a key enzyme in ceramide synthesis, resulting in insulin resistance in high-fat diet-induced obese mice. Moreover, genetic and pathophysiologic inhibition of the HIF-2α-NEU3-ceramide pathway can alleviate insulin resistance, suggesting that these could be potential drug targets for the treatment of metabolic diseases. Herein, the effects of hypoxia and ceramide, especially in the intestine, on metabolic diseases are summarized. | Qing-Song Xia Fu-Er Lu Fan Wu Zhao-Yi Huang Hui Dong Li-Jun Xu Jing Gong | 2020 | World Journal of Gastroenterology2020,26,18: | 12 |
| 18 | Bile salts inhibit growth and induce apoptosis of culture human normal esophageal mucosal epithelial cells显示文摘AIM: To investigate the effect of six bile salts:glycocholate (GC), glycochenodeoxycholate (GCDC),glycodeoxycholate (GDC), taurocholate (TC),taurochenodeoxycholate (TCDC), taurodeoxycholate (TDC), and their mixture on cultured human normal esophageal mucosal epithelial cells.METHODS: Human normal esophageal mucosal epithelial cells were cultured with serum-free keratinocyte medium. 3-[4,5-Dimethylthiaolyl]-2,5-diphenyl-tetrazolium bromide assay was applied to the detection of cell proliferation. Apoptotic morphology was observed by phase-contrast video microscopy and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay. Sub-G1 DNA fragmentations and early apoptotic cells were assayed by flow cytometry (FCM) with propidium iodide (PI) staining and annexin V-FITC conjugated with PI staining.Apoptotic DNA ladders on agarose gel electrophoresis were observed.RESULTS: Except for GC, GCDC, GDC, TC, TCDC, TDC and their mixture could initiate growth inhibition of esophageal mucosal epithelial cells in a dose- and time-dependent manner. TUNEL and FCM assays demonstrated that the bile salts at 500 μmol/L and their mixture at 1 500 μmol/L induced apoptosis except for GC. The percentage of sub-G1 detected by FCM with PI staining was 83.5% in cells treated with 500μmol/L TC for 2 h, and 19.8%, 20.4%, 25.6%, 13.5%, and 75.8% in cells treated with 500 μmol/L GCDC, TCDC, GDC,TDC, and 1 500 μmol/L mixture for 24 h, respectively,which were higher than that of the control (1.5%). The percentage was 1.4% in cells with 500 μmol/L GC for 24 h.DNA ladders on agarose gel electrophoresis were seen in cells treated with 500 μmol/L TC for 2 h and 1 500 μmol/Lmixture for 24 h.CONCLUSION: All GCDC, GDC, TC, TCDC, TDC and their mixture can inhibit growth and induce apoptosis of cultured human normal esophageal mucosal epithelial cells, but GC is well tolerated by the cells. | Ru Zhang Jun Gong Hui Wang Li Wang | 2005 | World Journal of Gastroenterology2005,11,41: | 11 |
| 19 | Anti-proliferation effects of Twist gene silencing in gastric cancer SGC7901 cells显示文摘AIM:To study the role of Twist gene in gastric cancer by gene silencing,including the potential of induction of apoptosis,cell cycle arrest,and proliferation inhibition in human malignant gastric SGC7901 cells.METHODS:The expression level of Twist in gastric cancer samples was measured by immunohistochemistry.The effects of Twist gene silencing were detected at both m RNA and protein levels by RT-PCR and Western blot.We also evaluated the cell proliferation and apoptosis by CCK-8 assay and flow cytometry.We determined the activity of caspase-3 and caspase-9 with a caspase activity assay kit.Cell cycle distribution was analyzed by flow cytometry.Cell migration and invasion ability was evaluated by wound scratch assay and Boyden chamber assay.RESULTS:Twist protein was highly expressed in gastric cancer samples.Twist gene silencing significantly induced apoptosis,cell cycle arrest at G0/G1 phase,proliferation inhibition,and reduced the ability of migration and invasion in human gastric cancer SGC7901 cells.Meanwhile,both caspase-3 and caspase-9 were activated.CONCLUSION:The Twist gene could serve as a potential molecular target for gene therapy of gastric cancer with targeted small interfering RNA. | Hui Zhang Jian Gong Di Kong Hong-Yi Liu | 2015 | World Journal of Gastroenterology2015,21,10: | 11 |
| 20 | Strategies to improve aerobic granular sludge stability and nitrogen removal based on feeding mode and substrate显示文摘A systemic strategy was proposed to improve aerobic granular sludge(AGS)stability and nitrogen(N)removal efficiency by optimizing feeding mode and substrate aiming at complicated wastewater characteristics.Key functional groups at the genus level identified by high-throughput sequencing were evaluated as well.The results showed that anaerobic feeding mode and acetate promoted the compact AGS formation with excellent total nitrogen(TN)removal efficiency(averaging 91.7%±4.1%)at various dissolved oxygen conditions.While the aerobic feeding mode led to a loose AGS structure with a vulnerable anaerobic core and poor TN removal efficiency(averaging58.8%±7.4%).Simultaneous nitrification and denitrification process played the dominant role in N removal in compact AGS over the alternating nitrification and denitrification process.High-concentration glucose undermined feast-famine condition with filamentous bacteria growth out of granule and decreased TN removal efficiency to 67.3%±15.2%.Lower food to microorganism ratio may result in a lower N removal rate attributed to the sharply increased biomass concentration fed by glucose.Ammonia-oxidizing bacteria,nitrite-oxidizing bacteria,denitrifying bacteria,and denitrifying phosphorus accumulation organisms enriched during AGS granulation also contributed to the efficient N removal.The proposed strategy provided insights into the relationship between various factors and stable AGS formation,and systemic operation methods for various complicated wastewater treatment. | Quan Yuan Hui Gong Hao Xi Heng Xu Zhengyu Jin Nasir Ali Kaijun Wang | 2019 | Journal of Environmental Sciences2019,31,10: | 10 |
