| 2 | Modeling study of regional severe hazes over mid-eastern China in January 2013 and its implications on pollution prevention and control显示文摘The Nested Air Quality Prediction Model System(NAQPMS)was used to investigate the temporal and spatial variations of PM2.5over tropospheric central eastern China in January 2013.The impact of regional transport and its implications on pollution prevention and control were also examined.Comparison between simulated and observed PM2.5showed NAQPMS was able to reproduce the evolution of PM2.5during heavy haze episodes.The results indicated that regional transport of PM2.5played an important role in regional haze episodes in the city cluster including Hebei,Beijing and Tianjin(HBT).The cross-city clusters transport outside HBT and transport among cities inside HBT contributed 20%–35%and 26%–35%of PM2.5as compared with local emission,in HBT respectively.To meet the Air Quality Standards for Grade II,90%,90%and65%of emissions would have to be cut down in Hebei,Tianjin and Beijing,if non-control strategy was taken in the surrounding city clusters of HBT.This implicated that control of emissions in one city cluster is not sufficient to reduce regional haze events,and joint efforts among city clusters are essential.Besides regional transports,two-way feedback between boundary-layer evolution and PM2.5also significantly contributed to the formation of heavy hazes,which contributed 30%of monthly average PM2.5concentration in HBT. | WANG ZiFa LI Jie WANG Zhe YANG WenYi TANG Xiao GE BaoZhu YAN PinZhong ZHU LiLi CHEN XueShun CHEN HuanSheng WAND Wei LI JianJun LIU Bing WANG XiaoYan WAND Wei ZHAO YiLin LU Ning SU DeBin | 2014 | Science China Earth Sciences2014，57，1： | 106 |
| 3 | On the origin and continuing evolution of SARS-CoV-2显示文摘The SARS-Co V-2 epidemic started in late December 2019 in Wuhan, China, and has since impacted a large portion of China and raised major global concern. Herein, we investigated the extent of molecular divergence between SARS-CoV-2 and other related coronaviruses. Although we found only 4% variability in genomic nucleotides between SARS-CoV-2 and a bat SARS-related coronavirus(SARSr-CoV;Ra TG13), the difference at neutral sites was 17%, suggesting the divergence between the two viruses is much larger than previously estimated. Our results suggest that the development of new variations in functional sites in the receptor-binding domain(RBD) of the spike seen in SARS-Co V-2 and viruses from pangolin SARSr-Co Vs are likely caused by natural selection besides recombination. Population genetic analyses of 103 SARS-CoV-2 genomes indicated that these viruses had two major lineages(designated L and S), that are well defined by two different SNPs that show nearly complete linkage across the viral strains sequenced to date. We found that L lineage was more prevalent than the S lineage within the limited patient samples we examined. The implication of these evolutionary changes on disease etiology remains unclear.These findings strongly underscores the urgent need for further comprehensive studies that combine viral genomic data, with epidemiological studies of coronavirus disease 2019(COVID-19). | Xiaolu Tang Changcheng Wu Xiang Li Yuhe Song Xinmin Yao Xinkai Wu Yuange Duan Hong Zhang Yirong Wang Zhaohui Qian Jie Cui Jian Lu | 2020 | National Science Review2020，7，6： | 67 |

| 6 | Subduction history of the Paleo-Pacific slab beneath Eurasian continent: Mesozoic-Paleogene magmatic records in Northeast Asia显示文摘This paper presents a review on the rock associations, geochemistry, and spatial distribution of Mesozoic-Paleogene igneous rocks in Northeast Asia. The record of magmatism is used to evaluate the spatial-temporal extent and influence of multiple tectonic regimes during the Mesozoic, as well as the onset and history of Paleo-Pacific slab subduction beneath Eurasian continent. Mesozoic-Paleogene magmatism at the continental margin of Northeast Asia can be subdivided into nine stages that took place in the Early-Middle Triassic, Late Triassic, Early Jurassic, Middle Jurassic, Late Jurassic, early Early Cretaceous, late Early Cretaceous, Late Cretaceous, and Paleogene, respectively. The Triassic magmatism is mainly composed of adakitic rocks,bimodal rocks, alkaline igneous rocks, and A-type granites and rhyolites that formed in syn-collisional to post-collisional extensional settings related to the final closure of the Paleo-Asian Ocean. However, Triassic calc-alkaline igneous rocks in the Erguna-Xing'an massifs were associated with the southward subduction of the Mongol-Okhotsk oceanic slab. A passive continental margin setting existed in Northeast Asia during the Triassic. Early Jurassic calc-alkaline igneous rocks have a geochemical affinity to arc-like magmatism, whereas coeval intracontinental magmatism is composed of bimodal igneous rocks and A-type granites. Spatial variations in the potassium contents of Early Jurassic igneous rocks from the continental margin to intracontinental region, together with the presence of an Early Jurassic accretionary complex, reveal that the onset of the PaleoPacific slab subduction beneath Eurasian continent occurred in the Early Jurassic. Middle Jurassic to early Early Cretaceous magmatism did not take place at the continental margin of Northeast Asia. This observation, combined with the occurrence of low-altitude biological assemblages and the age population of detrital zircons in an Early Cretaceous accretionary complex,indicates that a strike-slip tectonic regime existed between the continental margin and Paleo-Pacific slab during the Middle Jurassic to early Early Cretaceous. The widespread occurrence of late Early Cretaceous calc-alkaline igneous rocks, I-type granites, and adakitic rocks suggests low-angle subduction of the Paleo-Pacific slab beneath Eurasian continent at this time. The eastward narrowing of the distribution of igneous rocks from the Late Cretaceous to Paleogene, and the change from an intracontinental to continental margin setting, suggest the eastward movement of Eurasian continent and rollback of the PaleoPacific slab at this time. | Jie TANG Wenliang XU Feng WANG Wenchun GE | 2018 | Science China Earth Sciences2018，61，5： | 48 |
| 7 | Metastatic human hepatocellular carcinoma models in nude mice and cell line with metastatic potential显示文摘Metastatic human HCC model is needed for the studies on mechanism and intervention of metastatic recurrence. By using orthotopic implantation of histologically intact tissues of 30 surgical specimens, a patient like metastatic model of human HCC in nude mice (LCI-D20)and a Iow metastatic model of human HCC in nude mice LCI-D35 ) have been established. All mice with transplanted LCI-D20 tumors exhibited extremely high metastatic ability including spontaneous metastasis to liver, lungs, lymph nodes and peritoneal seeding.Remarkable difference was also found in expression of some of the invasiveness related genes and growth factors between the LCI-D20 and LCI-D35 tumors. PAI-Iincreased gradually following tumor progression in LCID20 model, and correlated with tumor size and AFP level,Phasic expression of tissue intercellular adhesion molecule-I in this model was also observed. Using corneal micropocket model, it was demonstrated that the vascular response induced by LCI-D20 tumor was stronger than that induced by LCI-D35 tumor. Similar report on metastatic human HCC model in nude mice and human HCC cell line with metastatic potential was rarely found in the literature. This LCI-D20 model has been widely used for the studies on intervention of metastasis, including antiangiogenesis, antisense approach, metalloproteinase inhibitor, differentiation inducer, etc. It is concluded that the establishment of metastatic human HCC model in nude mice and human HCC cell line with metastatic potential will provide important models for the in vivo and in vitro study of HCC invasiveness, angiogenesis as well as intervention of HCC recurrence. | Zhao-You Tang Fan-Xian Sun Jian Tian Sheng-Long Ye Yin-Kun Liu Kang-Da Liu Qiong Xue Jie Chen Jing-Lin Xia Lun-Xiu Qin Hui-Chuan Sun Lu Wang Jian Zhou Yan Li Zeng-Chen Ma Xin-Da Zhou Zhi-Quan Wu Zhi-Ying Lin Bing-Hui Yang Liver Cancer Institute of Fudan University and Zhongshan Hospital,Shanghai 200032,China | 2001 | World Journal of Gastroenterology2001，7，5： | 34 |
| 8 | Impact of postoperative complications on long-term survival after radical resection for gastric cancer显示文摘AIM: To investigate the potential impact of complications in gastric cancer patients who survive the initial postoperative period. METHODS: Between January 1, 2005 and December 31, 2006, 432 patients who received curative gastrectomy with D2 lymph node dissection for gastric cancer at our department were studied. Associations between clinicopathological factors [age, sex, American Society of Anesthesiologists grade, body mass index, tumornode-metastases (TNM) stage and tumor grade], including postoperative complications (defined as any deviation from an uneventful postoperative course within 30 d of the operation and survival rates) and treatment-specific factors (blood transfusion, neoadjuvant therapy and duration of surgery). Patients were divided into 2 groups: with (n = 54) or without (n = 378) complications. Survival curves were compared between the groups, and univariate and multivariate models were conducted to identify independent prognostic factors. RESULTS: Among the 432 patients evaluated, 61 com-plications occurred affecting 54 patients (12.50%).Complications included anastomotic leakages, gastric motility disorders, anastomotic block, wound infections, intra-abdominal abscesses, infectious diarrhea, bleeding, bowel obstructions, arrhythmias, angina pectoris, pneumonia, atelectasis, thrombosis, unexplained fever, delirium, ocular fungal infection and multiple organ failure. American Society of Anesthesiologists grade, body mass index, combined organ resection and median duration of operation were associated with higher post-operative complications. The 1-, 3- and 5-year survival rates were 83.3%, 53.2% and 37.5%, respectively. In the univariate analysis, the size of lesions, TNM stage, blood transfusion, lymphovascular invasion, perineural invasion, neoadjuvant chemotherapy, and postoperative complications were significant predictors of overall survival. In the multivariate analysis, only TNM stage and the presence of complications remained significant predictors of reduced survival. CONCLUSION: The occurrence of in-hospital postoperative complications was an independent predictor of worse 5-year overall survival rate after radical resection of gastric cancer. | Qing-Guo Li Ping Li Dong Tang Jie Chen Dao-Rong Wang | 2013 | World Journal of Gastroenterology2013，19，25： | 33 |
| 9 | Hygroscopic growth of aerosol scattering coefficient:A comparative analysis between urban and suburban sites at winter in Beijing显示文摘A humidity controlled inlet system was developed to measure the hygroscopic growth of aerosol scattering coefficient in conjunction with nephelometry at an urban site of Chinese Academy of Meteorological Sciences (CAMS) in Beijing and a rural site at Shangdianzi Regional Background Air Pollution Monitoring Station (SDZ) outside Beijing during winter, from December 2005 to January 2006. Measurements were carried out at a wavelength of 525 nm with an Ecotech M9003 nephelometer. The hygroscopic growth function (or factor) of the aerosol scattering coefficient f(RH) increased continuously with increasing relative humidity (RH) and showed no obvious 'step-like' deliquescent behavior at both sites during the experiment. The average growth factor f(RH) at the SDZ site could reach 1.5 when RH increased from less than 40% to 92%, and to 2.1 at the CAMS site when RH increased from less than 40% to 93%. The average hygroscopic growth factor at a relative humidity of 80%, f(RH = 80 ± 1%), was found to be about 1.26 ± 0.15 at CAMS and 1.24 ± 0.11 at SDZ. Further analysis indicated that under relatively polluted conditions, the average hygroscopic growth factor was higher at the CAMS site than that at the SDZ site. However, under relatively clean air conditions, the difference between the two sites was small, showing a hygroscopic growth behavior similar to those of burning biomass or blowing dust. These results reflected the different characteristics of aerosol types at the two sites. | Peng Yan Xiaole Pan Jie Tang Xiuji Zhou Renjian Zhang Limin Zeng | 2009 | Particuology2009，7，1： | 30 |

| 11 | Characterizing the dynamics of soil organic carbon in grasslands on the Qinghai-Tibetan Plateau显示文摘Carbon dynamics of grasslands on the Qinghai-Tibetan Plateau may play an important role in regional and global carbon cycles. The CENTURY model (Version 4.5) is used to examine temporal and spatial variations of soil organic carbon (SOC) in grasslands on the Plateau for the period from 1960 to 2002. The model successfully simulates the dynamics of aboveground carbon and soil surface SOC at the soil depth of 0-20 cm and the simulated results agree well to the measurements. Examination of SOC for eight typical grasslands shows different patterns of temporal variation in different ecosystems in 1960-2002. The extent of temporal variation increases with the increase of SOC of ecosystem. SOC increases first and decreases quickly then during the period from 1990 to 2000. Spatially, SOC density obtained for the equilibrium condition declines gradually from the southeast to the northwest on the plateau and showed a high heterogeneity in the eastern plateau. The results suggest that (i) SOC den-sity in the alpine grasslands shows remarkable response to climate change during the 42 years, and (ii) the net carbon exchange rate between the alpine grassland ecosystems and the atmosphere increases from 1990 to 2000 as compared with that before 1990. | ZHANG YongQiang TANG YanHong JIANG Jie YANG YongHui | 2007 | Science China Earth Sciences2007，50，1： | 25 |
| 12 | An autotrophic nitrogen removal process:Short-cut nitrification combined with ANAMMOX for treating diluted effluent from an UASB reactor fed by landfill leachate显示文摘A combined process consisting of a short-cut nitrification (SN) reactor and an anaerobic ammonium oxidation upflow anaerobic sludge bed (ANAMMOX) reactor was developed to treat the diluted effluent from an upflow anaerobic sludge bed (UASB) reactor treating high ammonium municipal landfill leachate.The SN process was performed in an aerated upflow sludge bed (AUSB) reactor (working volume 3.05 L),treating about 50% of the diluted raw wastewater.The ammonium removal efficiency and the ratio of NO 2 N to NOx-N in the effluent were both higher than 80%,at a maximum nitrogen loading rate of 1.47 kg/(m 3 ·day).The ANAMMOX process was performed in an UASB reactor (working volume 8.5 L),using the mix of SN reactor effluent and diluted raw wastewater at a ratio of 1:1.The ammonium and nitrite removal efficiency reached over 93% and 95%,respectively,after 70-day continuous operation,at a maximum total nitrogen loading rate of 0.91 kg/(m 3 ·day),suggesting a successful operation of the combined process.The average nitrogen loading rate of the combined system was 0.56 kg/(m 3 ·day),with an average total inorganic nitrogen removal efficiency 87%.The nitrogen in the effluent was mostly nitrate.The results provided important evidence for the possibility of applying SN-ANAMMOX after UASB reactor to treat municipal landfill leachate. | Jie Liu Jian'e Zuo Tang Yang Shuquan Zhu Sulin Kuang Kaijun Wang | 2010 | Journal of Environmental Sciences2010，22，5： | 26 |
| 13 | Aggregation-induced emission: a coming-of-age ceremony at the age of eighteen显示文摘Aggregation-induced emission(AIE) has drawn great attention worldwide for its unique optical phenomenon and huge potential applications. Since coined by Ben Zhong Tang et al. in 2001, AIE has been deeply investigated and widely utilized in many important areas, such as organic light-emitting diode(OLED), sensor, and bio-imaging. Herein, we highlight some important progress of AIE in these eighteen years, including the exploration of internal mechanism and potential applications. Furthermore,some other interestingly emissive behaviors, originating but distinguishing from the AIE concept, are presented. It is anticipated an overall understanding about AIE could be easily caught from this short review for scientists, no matter whether they are involved in this exciting and rising research area or not. | Jie Yang Zhenguo Chi Weihong Zhu Ben Zhong Tang Zhen Li | 2019 | Science China Chemistry2019，62，9： | 25 |
| 14 | Trends of the precipitation acidity over China during 1992–2006显示文摘The trends of the precipitation acidity from 1992 to 2006 were studied, based on the long-term acid rain observations at 74 sites in China. The results show that there was no remarkable change or extension of acid rain area (i.e., with annual mean of precipitation pH<5.6) during the 15 years. The largest and continuous acid rain area exists in the south of the Yangtze River, while the acid rain areas north of the Yangtze River remain separate. The severe acid rain area (i.e., with annual mean of precipitation pH<4.5) exists mainly in the south of the Yangtze River. The overall precipitation acidity for the 74 stations showed different trends before 1999 and after 2000. In the period 1992–1999, the precipitation acidity at most of the sites remained steady or showed a decreasing trend. After 2000, however, an increasing trend of the precipitation acidity was observed at many sites in North China, Central China, East China, and South China. As a result, the pattern of acid rain area changed during 1992–2006. The precipitation over North China, Central China, and South China became more acidified in the 15 years, with more pronounced trends in North China and the north of Central China. A slight decrease in the precipitation acidity was found in Southwest China, an area characterized as severest acid rain area for about two decades after the early 1980s. Consequently, the center of severe acid rain area in the south of the Yangtze River moved eastwards. The non-hydrogen conductivity (NHC), which is defined as the difference between the measured precipitation conductivity and the H+ conductivity calculated from measured pH, was estimated and treated as a proxy of soluble ions in precipitation. The result shows that the overall trend of the NHC before 1999 was pronounced and positive, while the trend after 2000 was inconspicuous or slightly negative. During 2000–2006, the change rate of pH was positively correlated to that of the NHC at 21 sites, implying that the increasing acidities found at these sites may partly be attributed to the decrease in the concentration of airborne particulate matter in recent years. | TANG Jie XU XiaoBin BA Jin WANG ShuFeng | 2010 | Chinese Science Bulletin2010，55，17： | 22 |

| 18 | Remimazolam benzenesulfonate anesthesia effectiveness in cardiac surgery patients under general anesthesia显示文摘BACKGROUND Sedation with propofol injections is associated with a risk of addiction,but remimazolam benzenesulfonate is a comparable anesthetic with a short elimination half-life and independence from cell P450 enzyme metabolism.Compared to remimazolam,remimazolam benzenesulfonate has a faster effect,is more quickly metabolized,produces inactive metabolites and has weak drug interactions.Thus,remimazolam benzenesulfonate has good effectiveness and safety for diagnostic and operational sedation.AIM To investigate the clinical value of remimazolam benzenesulfonate in cardiac surgery patients under general anesthesia.METHODS A total of 80 patients who underwent surgery in the Department of Cardiothoracic Surgery from August 2020 to April 2021 were included in the study.Using a random number table,patients were divided into two anesthesia induction groups of 40 patients each:remimazolam(0.3 mg/kg remimazolam benzenesulfonate)and propofol(1.5 mg/kg propofol).Hemodynamic parameters,inflammatory stress response indices,respiratory function indices,perioperative indices and adverse reactions in the two groups were monitored over time for comparison.RESULTS At pre-anesthesia induction,the remimazolam and propofol groups did not differ regarding heart rate,mean arterial pressure,cardiac index or volume per wave index.After endotracheal intubation and when the sternum was cut off,mean arterial pressure and volume per wave index were significantly higher in the remimazolam group than in the propofol group(P<0.05).After endotracheal intubation,the oxygenation index and the respiratory index did not differ between the groups.After endotracheal intubation and when the sternum was cut off,the oxygenation index values were significantly higher in the remimazolam group than in the propofol group(P<0.05).Serum interleukin-6 and tumor necrosis factor-αlevels 12 h after surgery were significantly higher than before surgery in both groups(P<0.05).The observation indices were re-examined 2 h after surgery,and the epinephrine,cortisol and blood glucose levels were significantly higher in the remimazolam group than in the propofol group(P<0.05).The recovery and extubation times were significantly lower in the remimazolam group than in the propofol group(P<0.05);there were significantly fewer adverse reactions in the remimazolam group(10.00%)than in the propofol group(30.00%;P<0.05).CONCLUSION Compared with propofol,remimazolam benzenesulfonate benefited cardiac surgery patients under general anesthesia by reducing hemodynamic fluctuations.Remimazolam benzenesulfonate influenced the surgical stress response and respiratory function,thereby reducing anesthesia-related adverse reactions. | Fang Tang Jian-Min Yi Hong-Yan Gong Zi-Yun Lu Jie Chen Bei Fang Chen Chen Zhi-Yi Liu | 2021 | World Journal of Clinical Cases2021，9，34： | 19 |
| 19 | Nonlinear hierarchy-structured predictive control design for a generic hypersonic vehicle显示文摘A hierarchy-structured predictive controller is designed and analyzed for rotation motion dynamics of a generic hypersonic vehicle(GHV).This vehicle model has fast variability,is highly nonlinear,and includes uncertain parameters.The controller contains two subsystems,the inner-fast-loop nonlinear generable predictive controller(NGPC)and the outer-slow-loop NGPC,both of which are designed by the closed-form optimal generable predictive control method.Thus,the heavy on-line computational burden in the classical predictive control method is avoided.The hierarchy structure of the control system decreases the relative degree of each subsystem and helps increase the dynamic response speed of the attitude controller.In order to improve the robustness of the control system,a feedback correction algorithm is proposed that corrects the calculation error between the predictive model and the real dynamic model.Simulation studies are conducted for the trimmed cruise conditions of an altitude of 33.5 km and Mach 15 to investigate the responses of the vehicle to the step commands of angle of attack,sideslip angle,and bank angle.The simulation studies demonstrate that the proposed controller is robust with respect to the parametric uncertainties and atmospheric disturbance,and meets the performance requirements of GHV with acceptable control inputs. | WANG Peng TANG GuoJian LIU LuHua WU Jie | 2013 | Science China(Technological Sciences)2013，56，8： | 18 |
