| 1 | An updated estimation of the risk of transmission of the novel coronavirus(2019-nCov)显示文摘The basic reproduction number of an infectious agent is the average number of infections one case can generate over the course of the infectious period,in a naïve,uninfected population.It is well-known that the estimation of this number may vary due to several methodological issues,including different assumptions and choice of parameters,utilized models,used datasets and estimation period.With the spreading of the novel coronavirus(2019-nCoV)infection,the reproduction number has been found to vary,reflecting the dynamics of transmission of the coronavirus outbreak as well as the case reporting rate.Due to significant variations in the control strategies,which have been changing over time,and thanks to the introduction of detection technologies that have been rapidly improved,enabling to shorten the time from infection/symptoms onset to diagnosis,leading to faster confirmation of the new coronavirus cases,our previous estimations on the transmission risk of the 2019-nCoV need to be revised.By using time-dependent contact and diagnose rates,we refit our previously proposed dynamics transmission model to the data available until January 29th,2020 and re-estimated the effective daily reproduction ratio that better quantifies the evolution of the interventions.We estimated when the effective daily reproduction ratio has fallen below 1 and when the epidemics will peak.Our updated findings suggest that the best measure is persistent and strict self-isolation.The epidemics will continue to grow,and can peak soon with the peak time depending highly on the public health interventions practically implemented. | Biao Tang Nicola Luigi Bragazzi Qian Li Sanyi Tang Yanni Xiao Jianhong Wu | 2020 | Infectious Disease Modelling2020，5，1： | 54 |
| 2 | Emergence and prevalence of naturally occurring lower virulent African swine fever viruses in domestic pigs in China in 2020显示文摘African swine fever virus(ASFV)has been circulating in China for more than two years,and it is not clear whether the biological properties of the virus have changed.Here,we report on our surveillance of ASFVs in seven provinces of China,from June to December,2020.A total of 22 viruses were isolated and characterized as genotype II ASFVs,with mutations,deletions,insertions,or short-fragment replacement occurring in all isolates compared with Pig/HLJ/2018(HLJ/18),the earliest isolate in China.Eleven isolates had four different types of natural mutations or deletion in the EP402R gene and displayed a nonhemadsorbing(non-HAD)phenotype.Four isolates were tested for virulence in pigs;two were found to be as highly lethal as HLJ/18.However,two non-HAD isolates showed lower virulence but were highly transmissible;infection with 106 TCID50 dose was partially lethal and caused acute or sub-acute disease,whereas 103 TCID50 dose caused non-lethal,sub-acute or chronic disease,and persistent infection.The emergence of lower virulent natural mutants brings greater difficulty to the early diagnosis of ASF and creates new challenges for ASFV control. | Encheng Sun Zhenjiang Zhang Zilong Wang Xijun He Xianfeng Zhang Lulu Wang Wenqing Wang Lianyu Huang Fei Xi Haoyue Huangfu Ghebremedhin Tsegay Hong Huo Jianhong Sun Zhijun Tian Wei Xia Xuewu Yu Fang Li Renqiang Liu Yuntao Guan Dongming Zhao Zhigao Bu | 2021 | Science China(Life Sciences)2021，64，5： | 46 |
| 3 | China National Medical Products Administration approval summary:anlotinib for the treatment of advanced non-small cell lung cancer after two lines of chemotherapy显示文摘Background:On May 8,2018,the China National Medical Products Administration(NMPA)approved anlotinib,an orally administered anti-angiogenesis inhibitor,for the treatment of patients with advanced non-small cell lung can-cer(NSCLC)who have progressed after treatment with two or more lines of prior systemic chemotherapy.Main body of the abstract:China NMPA reviewed and inspected a regional double-blinded,placebo-controlled,Phase III trial comparing the overall survival(OS)of NSCLC patients between the anlotinib and placebo arms.A total of 437 patients were randomized(2:1)to receive either anlotinib(n=294)or placebo(n=143)once daily on a 2-week on and 1-week off schedule.Patients with epidermal growth factor receptor(EGFR)or activating anaplastic lymphoma kinase(ALK)genomic tumor aberrations should have disease progression on NMPA-approved therapy.Anlotinib is the first NMPA-approved drug for patients with advanced NSCLC who have progressed on at least two lines of prior systemic chemotherapies in China.The approval was based on a statistically and clinically significant improvement in median OS with anlotinib(9.46 months)compared with placebo[6.37 months;hazard ratio(HR])=0.70,95%confidence interval(CI)=0.55-0.89;two-sided log-rank P=0.002].The confirmed objective response rate(ORR)was 9.2%in the anlotinib arm and 0.7%in the placebo arm.The median duration of response(DoR)was 4.83 months,with a 95%CI of 3.31-6.97 months.The toxicity profile of anlotinib was consistent with that of known anti-angiogenesis inhibitors.Common adverse drug reactions(ADRs)in anlotinib-treated patients included hypertension(67.4%),hand-foot syndrome(43.9%),hemoptysis(14.0%),thyroid stimulating hormone(TSH)elevation(46.6%),and corrected QT interval(QTc)prolongation(26.2%).Short conclusion:Anlotinib demonstrated a clinically significant OS prolongation as a novel therapeutic option for advanced or metastatic NSCLC following at least two lines of chemotherapy. | Ming Zhou Xiaoyuan Chen Hong Zhang Lin Xia Xin Tong Limin Zou Ruimin Hao Jianhong Pan Xiao Zhao Dongmei Chen Yuanyuan Song Yueli Qi Ling Tang Zhifang Liu Rong Gao Yuankai Shi Zhimin Yang | 2019 | Cancer Communications2019，39，1： | 35 |
| 4 | China's wetland change (1990-2000) determined by remote sensing显示文摘Two wetland maps for the entire China have been produced based on Landsat data acquired around 1990 and 2000. Wetlands in China have been divided into 3 broad categories with 15 sub-categories except rice fields. In 1990, the total wetland area in China was 355208 km2 whereas in 2000 it dropped to 304849 km2 with a net loss of 50360 km2. During an approximate 10-year period, inland wetland reduced from 318326 to 257922 km2, coastal wetland dropped from 14335 to 12015 km2, while artificial wetland increased from 22546 to 34911 km2. The greatest natural wetland loss occurred in Heilongjiang, Inner Mon- golia, and Jilin with a total loss of over 57000 km2 of wetland. In western China, over 13000 km2 of wetlands were newly formed in Xinjiang, Tibet, and Qinghai. About 12000 km2 of artificial wetlands were also added for fish farm and reservoir constructions. The newly formed wetlands in western China were caused primarily by climate warming over that region whereas the newly created artificial wetlands were caused by economic developments. China’s wetland loss is caused mainly by human activities. | Peng Gong ZhenGuo Niu Xiao Cheng KuiYi Zhao DeMin Zhou JianHong Guo Lu Liang XiaoFeng Wang DanDan Li HuaBing Huang et al. | 2010 | Science China Earth Sciences2010，53，7： | 28 |
| 5 | Natural killer cell-triggered vascular transformation:maternal care before birth?显示文摘Natural killer(NK)cells are found in lymphoid and non-lymphoid organs.In addition to important roles in immune surveillance,some NK cells contribute to angiogenesis and circulatory regulation.The uterus of early pregnancy is a non-lymphoid organ enriched in NK cells that are specifically recruited to placental attachment sites.In species with invasive hemochorial placentation,these uterine natural killer(uNK)cells,via secretion of cytokines,chemokines,mucins,enzymes and angiogenic growth factors,contribute to the physiological change of mesometrial endometrium into the unique stromal environment called decidua basalis.In humans,uNK cells have the phenotype CD56^(bright) CD16^(dim) and they appear in great abundance in the late secretory phase of the menstrual cycle and early pregnancy.Gene expression studies indicate that CD56^(bright) CD16^(dim) uterine and circulating cells are functionally distinct.In humans but not mice or other species with post-implantation decidualization,uNK cells may contribute to blastocyst implantation and are of interest as therapeutic targets in female infertility.Histological and genetic studies in mice first identified triggering of the process of gestation spiral arterial modification as a major uNK cell function,achieved via interferon(IFN)-c secretion.During spiral arterial modification,branches from the uterine artery that traverse the endometrium/decidua transiently lose their muscular coat and ability to vasoconstrict.The expression of vascular markers changes from arterial to venous as these vessels dilate and become low-resistance,high-volume channels.Full understanding of the vascular interactions of human uNK cells is difficult to obtain because endometrial time-course studies are not possible in pregnant women.Here we briefly review key information concerning uNK cell functions from studies in rodents,summarize highlights concerning human uNK cells and describe our preliminary studies on development of a humanized,pregnant mouse model for in vivo investigations of human uNK cell functions. | Jianhong Zhang Zhilin Chen Graeme N Smith B.Anne Croy | 2011 | Cellular & Molecular Immunology2011，8，1： | 19 |

| 7 | Geographical characteristics of China’s wetlands derived from remotely sensed data显示文摘In this paper, we report the first wetland mapping of the entire China using Landsat enhanced thematic mapper plus (ETM+) data. These data were obtained from the Global Land Cover Facility at the University of Maryland spanning from 1999 to 2002. A total of 597 scenes of Landsat images were georeferenced and mosaiced. Manual image interpretation of satellite images was aided with elevation data, soil data, land cover/land use data and Google Earth. The minimum mapping unit is 10 pixel × 10 pixel, equivalent to 9 ha. The aim of our first round of mapping was only targeted at the boundary delineation of any type of wetland except those wetlands that are under agricultural use (i.e., paddy fields), which has already been well mapped by others. Our interpretation results indicate that a total of 359478 km2 of wetlands are of non-agricultural use. Among our preliminarily mapped wetland, 339353 km2 are inland wetland, 2786 km2 are non-agricultural artificial wetland, and 17609 km2 are coastal wetland. Because low-tide is rarely captured in satellite images, an under-estimation of coastal wetland is inevitable. We conducted some statistics based on our mapped wetlands and compared them with those previously obtained from a number of sources including a land cover/land use map made with satellite images during the late 1990s and early 2000s, a marshland map developed in approximately the same period, survey data of coastal wetland in early 1980s, and area data for approximately 400 larger patches of marshland in China compiled in 1996. Because some inconsistencies exist in the guidelines of those different wetland surveys, difference in area is expected. Some further comparison indicates that the wetland distributions derived from the preliminary wetland map are reasonable and more objective than other sources. The mapping process also indicated that the method adopted by us was efficient and cost-effective. We also found that in order to ensure comparability of the wetland maps developed at different times, a set of standard guidelines on the wetland categories to be mapped, and the mapping methods to be used must be well conceived, developed and effectively employed. We carried out some initial geographical analysis on the distribution of wetlands. | NIU ZhenGuo GONG Peng CHENG Xiao GUO JianHong WANG Lin HUANG HuaBing SHEN ShaoQing WU YunZhao WANG XiaoFeng WANG XianWei YING Qing LIANG Lu ZHANG LiNa WANG Lei YAO Qian YANG ZhenZhong GUO ZiQi DAI YongJiu | 2009 | Science China Earth Sciences2009，52，6： | 15 |

| 9 | Influences of different types of magnetic fields on HCFC-141b gas hydrate formation processes显示文摘In this study, visualizations and experiments are carried out on the influence of static and rotating magnetic fields on the characteristics of HCFC-141b gas hydrate formation, such as crystallization form, formation temperature and induction time. It has been found that a proper rotating magnetic field can considerably improve the low-pressure gas hydrate formation process, especially in increasing the formation temperature and shortening the induction time. The mor- phology of the gas hydrate formation appears rather complex and compact. However, a proper static magnetic field can make the gas hydrate crystal more organized, which will be benefit to heat transfer. | SHU Bifen MA Xiaolin GUO Kaihua LI Jianhong | 2004 | Science China Chemistry2004，47，5： | 14 |
| 10 | Transgenic rhesus monkeys carrying the human MCPH1 gene copies show human-like neoteny of brain development显示文摘Brain size and cognitive skills are the most dramatically changed traits in humans during evolution and yet the genetic mechanisms underlying these human-specific changes remain elusive.Here,we successfully generated 11 transgenic rhesus monkeys(8 first-generation and 3 second-generation)carrying human copies of MCPH1,an important gene for brain development and brain evolution.Brain-image and tissue-section analyses indicated an altered pattern of neural-cell differentiation,resulting in a delayed neuronal maturation and neural-fiber myelination of the transgenic monkeys,similar to the known evolutionary change of developmental delay(neoteny)in humans.Further brain-transcriptome and tissue-section analyses of major developmental stages showed a marked human-like expression delay of neuron differentiation and synaptic-signaling genes,providing a molecular explanation for the observed brain-developmental delay of the transgenic monkeys.More importantly,the transgenic monkeys exhibited better short-term memory and shorter reaction time compared with the wild-type controls in the delayed-matching-to-sample task.The presented data represent the first attempt to experimentally interrogate the genetic basis of human brain origin using a transgenic monkey model and it values the use of non-human primates in understanding unique human traits. | Lei Shi Xin Luo Jin Jiang Yongchang chen Cirong Liu Ting Hu Min Li Qiang Lin Yanjiao Li Jun Huang Hong Wang Yuyu Niu Yundi Shi Martin Styner Jianhong Wang Yi Lu Xuejin Sun Hualin Yu Weizhi Ji Bing Su | 2019 | National Science Review2019，6，3： | 12 |
| 11 | Microstructures of metallic film and diamond growth from Fe-Ni-C system显示文摘The microstructures of metallic film surrounding diamond have been systemically studied using the transmission electron microscopy (TEM) and the atom force microscopy (AFM). The film can be divided into three layers (inner layer near diamond, external layer near graphite and middle layer). The graphite cannot be directly transformed into diamond in the film at HTHP: there exists a parallelrelationship between (111) of γ-(Fe,Ni) and (110) of Fe3C in the inner layer; the sawtooth-like step morphology found by AFM on the film is similar to that of corresponding diamond surface. A new model for diamond growth at HPHT is proposed from the parallel relationship and sawtooth-like step morphology. It is believed that Fe3C may be a transitional phase in the course of diamond growth, γ-(Fe,Ni) in the inner layer can absorb carbon atom groups with lamella structure from Fe3C, and then the carbon groups stack on growing diamond. | XU Bin LI Musen YIN Longwei CUI Jianjun LIU Yuxian GONG Jianhong | 2002 | Chinese Science Bulletin2002，47，15： | 12 |
| 12 | Prognostic value of preoperative prognostic nutritional index and its associations with systemic inflammatory response markers in patients with stage Ⅲ colon cancer显示文摘Background: The prognostic nutritional index(PNI) has been widely applied for predicting survival outcomes of patients with various malignant tumors. Although a low PNI predicts poor prognosis in patients with colorectal cancer after tumor resection, the prognostic value remains unknown in patients with stage Ⅲ colon cancer undergoing curative tumor resection followed by adjuvant chemotherapy. This study aimed to investigate the prognostic value of PNI in patients with stage III colon cancer.Methods: Medical records of 274 consecutive patients with stage Ⅲ colon cancer undergoing curative tumor resection followed by adjuvant chemotherapy with oxaliplatin and capecitabine between December 2007 and December2013 were reviewed. The optimal PNI cutoff value was determined using receiver operating characteristic(ROC) curve analysis. The associations of PNI with systemic inflammatory response markers, including lymphocyte-to-monocyte ratio(LMR), neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), and C-reactive protein(CRP)level, and clinicopathologic characteristics were assessed using the Chi square or Fisher's exact test. Correlation analysis was performed using Spearman's correlation coefficient. Disease-free survival(DFS) and overall survival(OS)stratified by PNI were analyzed using Kaplan-Meier method and log-rank test, and prognostic factors were identified by Cox regression analyses.Results: The preoperative PNI was positively correlated with LMR(r= 0.483, P < 0.001) and negatively correlated with NLR(r =-0.441, P < 0.001), PLR(r =-0.607, P < 0.001), and CRP level(r =-0.333, P < 0.001). A low PNI(≤49.22)was significantly associated with short OS and DFS in patients with stage ⅢC colon cancer but not in patients with stage ⅢA/ⅢB colon cancer.In addition, patients with a low PNI achieved a longer OS and DFS after being treated with6-8 cycles of adjuvant chemotherapy than did those with < 6 cycles. Multivariate analyses revealed that PNI was independently associated with DFS(hazard ratios 2.001; 95% confidence interval 1.157-3.462; P = 0.013).Conclusion: The present study identified preoperative PNI as a valuable predictor for survival outcomes in patients with stage Ⅲ colon cancer receiving curative tumor resection followed by adjuvant chemotherapy. | Jianhong Peng Rongxin Zhang Yixin Zhao Xiaojun Wu Gong Chen Desen Wan Zhenhai Lu Zhizhong Pan | 2017 | Chinese Journal of Cancer2017，36，11： | 11 |

| 14 | Effect of protective coal seam mining and gas extraction on gas transport in a coal seam显示文摘A gas–solid coupling model involving coal seam deformation,gas diffusion and seepage,gas adsorption and desorption was built to study the gas transport rule under the effect of protective coal seam mining.The research results indicate:(1) The depressurization effect changes the stress state of an overlying coal seam and causes its permeability to increase,thus gas in the protected coal seam will be desorbed and transported under the effect of a gas pressure gradient,which will cause a decrease in gas pressure.(2) Gas pressure can be further decreased by setting out gas extraction boreholes in the overlying coal seam,which can effectively reduce the coal and gas outburst risk.The research is of important engineering significance for studying the gas transport rule in protected coal seam and providing important reference for controlling coal and gas outbursts in deep mining in China. | Yao Banghua Ma Qingqing Wei Jianping Ma Jianhong Cai Donglin | 2016 | International Journal of Mining Science and Technology2016，26，4： | 11 |
| 15 | pH-sensitive polymeric micelles triggered drug release for extracellular and intracellular drug targeting delivery显示文摘Most of the conventional chemotherapeutic agents used for cancer chemotherapy suffer from multidrug resistance of tumor cells and poor antitumor efficacy.Based on physiological differences between the normal tissue and the tumor tissue,one effective approach to improve the efficacy of cancer chemotherapy is to develop pH-sensitive polymeric micellar delivery systems.The copolymers with reversible protonationedeprotonation core units or acid-liable bonds between the therapeutic agents and the micelle-forming copolymers can be used to form pH-sensitive polymeric micelles for extracellular and intracellular drug smart release.These systems can be triggered to release drug in response to the slightly acidic extracellular fluids of tumor tissue after accumulation in tumor tissues via the enhanced permeability and retention effect,or they can be triggered to release drug in endosomes or lysosomes by pH-controlled micelle hydrolysis or dissociation after uptake by cells via the endocytic pathway.The pH-sensitive micelles have been proved the specific tumor cell targeting,enhanced cellular internalization,rapid drug release,and multidrug resistance reversal.The multifunctional polymeric micelles combining extracellular pH-sensitivity with receptor-mediated active targeting strategies are of great interest for enhanced tumor targeting.The micelles with receptor-mediated and intracellular pH targeting functions are internalized via receptor-mediated endocytosis followed by endosomal-pH triggered drug release inside the cells,which reverses multidrug resistance.The pH sensitivity strategy of the polymeric micelles facilitates the specific drug delivery with reduced systemic side effects and improved chemotherapeutical efficacy,and is a novel promising platform for tumor-targeting drug delivery. | Yanhua Liu Wenping Wang Jianhong Yang Chengming Zhou Jin Sun | 2013 | Asian Journal of Pharmaceutical Sciences2013，8，3： | 11 |
| 16 | Exposure to polycyclic aromatic hydrocarbons and risk for premature ovarian failure and reproductive hormones imbalance显示文摘Polycyclic aromatic hydrocarbons(PAHs)are a typical class of persistent organic pollutants that is ubiquitous worldwide.Previous animal studies suggested that PAHs had adverse effects on female reproduction.However,the human data regarding relationship of PAHs exposure with women reproductive health,such as ovarian dysfunction,are scarce.In this case-control study,the associations of serum levels of PAHs with the risk of premature ovarian failure(POF)and reproductive hormones in Chinese women were investigated,with recruiting 157 POF patients and 217 healthy women.The serum levels of 12 types of PAHs,as well as reproductive hormones,including follicle-stimulating hormone,luteinizing hormone and anti-mullerian hormone,were determined.In the logistic regression models,most individual PAH congeners showed significantly positive correlations with the risk of POF(p<0.05),except for fluorine and pyrene.Benzo(a)pyrene(BaP),as the most carcinogenic PAH congener,was observed to be significantly positively associated with the risk of POF.After adjustment for age,body mass index,educational levels and household income,per one-unit increase in the log-transformed BaP concentration was significantly correlated with 2.191-fold increased risk of POF(OR=2.191,95%CI:1.634-2.938,p<0.05).To the best of our knowledge,this is the first study to report an association between internal exposure levels of PAHs and the increased risk of POF in women. | Xiaoqing Ye Wuye Pan Chunming Li Xiaochen Ma Shanshan Yin Jianhong Zhou Jing Liu | 2020 | Journal of Environmental Sciences2020，32，5： | 10 |
| 17 | Ⅲ期结肠癌患者术前预后营养指数的预后价值及其与全身炎症反应标志物的相关性显示文摘背景与目的预后营养指数(prognostic nutritional index,PNI)已广泛应用于预测各种恶性肿瘤患者的生存结局。虽然低PNI预测肿瘤切除后的结直肠癌患者的预后不良,但对接受根治性肿瘤切除术后辅助化疗的Ⅲ期结肠癌患者的预后价值仍未知。本研究旨在探讨PNI对Ⅲ期结肠癌患者的预后价值。方法本文回顾了2007年12月至2013年12月期间,274例接受根治性肿瘤切除术后接受奥沙利铂和卡培他滨辅助化疗的Ⅲ期结肠癌的连续患者的医疗记录。采用受试者工作特征(receiver operating characteristic,ROC)曲线分析确定最佳PNI临界值。采用卡方检验或Fisher’s精确检验评估PNI与全身炎症反应标志物[包括淋巴细胞与单核细胞比值(lymphocyte-to-monocyte ratio,LMR)、中性粒细胞与淋巴细胞比值(neutrophil-to-lymphocyte ratio,NLR)、血小板与淋巴细胞比值(platelet-to-lymphocyte ratio,PLR)、C反应蛋白(C-reactive protein,CRP)水平]和临床病理特征的相关性。采用Spearman’s相关系数进行相关分析。采用Kaplan-Meier法和log-rank检验分析PNI分层的无病生存期(disease-free survival,DFS)和总生存期(overall survival,OS),并通过Cox回归分析确定预后因子。结果术前PNI与LMR呈正相关(r=0.483,P <0.001),与NLR(r=-0.441,P <0.001)、PLR(r=-0.607,P <0.001)和CRP水平(r=-0.333,P <0.001)呈负相关。在ⅢC期结肠癌患者中,低PNI(≤49.22)与短OS和DFS显著相关,而在ⅢA/ⅢB期结肠癌患者中则不相关。此外,在PNI低的患者中,接受6–8个疗程辅助化疗的患者比接受<6个疗程治疗的患者获得了更长的OS和DFS。多变量分析显示PNI与DFS独立相关(风险比=2.001;95%置信区间:1.157–3.462;P=0.013)。结论术前PNI是接受根治性肿瘤切除术后辅助化疗的Ⅲ期结肠癌患者生存结局的重要预测指标。 | Jianhong Peng Rongxin Zhang Yixin Zhao Xiaojun Wu Gong Chen Desen Wan Zhenhai Lu Zhizhong Pan | 2019 | 癌症2019，38，1： | 10 |
| 18 | An update: Epstein-Barr virus and immune evasion via microRNA regulation显示文摘Epstein-Barr virus(EBV) is an oncogenic virus that ubiquitously establishes life-long persistence in humans. To ensure its survival and maintain its B cell transformation function, EBV has developed powerful strategies to evade host immune responses. Emerging evidence has shown that micro RNAs(mi RNAs) are powerful regulators of the maintenance of cellular homeostasis. In this review, we summarize current progress on how EBV utilizes mi RNAs for immune evasion. EBV encodes mi RNAs targeting both viral and host genes involved in the immune response. The mi RNAs are found in two gene clusters, and recent studies have demonstrated that lack of these clusters increases the CD4^+ and CD8^+ T cell response of infected cells. These reports strongly indicate that EBV mi RNAs are critical for immune evasion. In addition, EBV is able to dysregulate the expression of a variety of host mi RNAs, which influence multiple immune-related molecules and signaling pathways. The transport via exosomes of EBV-regulated mi RNAs and viral proteins contributes to the construction and modification of the inflammatory tumor microenvironment.During EBV immune evasion, viral proteins, immune cells, chemokines, pro-inflammatory cytokines, and pro-apoptosis molecules are involved. Our increasing knowledge of the role of mi RNAs in immune evasion will improve the understanding of EBV persistence and help to develop new treatments for EBV-associated cancers and other diseases. | Lielian Zuo Wenxin Yue Shujuan Du Shuyu Xin Jing Zhang Lingzhi Liu Guiyuan Li Jianhong Lu | 2017 | Virologica Sinica2017，32，3： | 9 |
| 19 | In-situ lunar dust deposition amount induced by lander landing in Chang’E-3 mission显示文摘China first in-situ lunar dust experiment is performed by a lunar dust detector in Chang’E-3 mission. The existed dust(less than 20 μm in diameter) properties, such as levitation, transportation and adhesion, are critical constraints for future lunar exploration program and even manned lunar exploration. Based on the problems discussed above, the in-situ lunar dust detector is originally designed to characterize dust deposition properties induced by lander landing as a function of environmental temperature, solar incident angle and orbit short circuit current on the northern Mare Imbrium, aiming to study lunar dust deposition properties induced by lander landing in depth. This paper begins with a brief of introduction of Chang’E-3 lunar dust detector design,followed by a series of experimental analysis of this instrument under different influencing factors, and concludes with lunar dust mass density deposition amount observed on the first lunar day is about 0.83 mg/cm^2, which is less than that observed in Apollo 11 mission because the landing site of Chang’E-3 has the youngest mare basalts comparing with previous Apollo and lunar landing sites. The young geologic environment is less weathered and thus it has thinner layer of lunar dust than Apollo missions’;hence, the amount of kicked-up lunar dust in Chang’E-3 mission is less than that in Apollo 11 mission. | ZHANG HaiYan WANG Yi CHEN LiPing ZHANG He LI CunHui ZHUANG JianHong LI DeTian WANG YongJun YANG ShengSheng LI XiongYao WANG WeiDong | 2020 | Science China(Technological Sciences)2020，63，3： | 9 |
| 20 | Recent advances in carbon dioxide capture and utilization with amines and ionic liquids显示文摘Global warming and climate change due to anthropogenic carbon dioxide(CO_(2))have aroused significant concerns at the global scale due to rapid economic growth in industries and other fields.Therefore,CO_(2)capture,use,and storage have become particularly important.In this review,general background and methods for CO_(2)capture and separation,in particular,on ionic liquids(ILs)-based solvents and materials,are discussed.Comprehensive surveys of ILs for CO_(2)absorption are presented,which focused mainly on experimental researches,and then the concept is extended to functionalized absorbents and recent developments for CO_(2)capture.Major advantages and disadvantages of amines-based and ILs-based absorbents are discussed in this review.Solutions of traditional amines(MEA,MDEA,DEA,AMP,PZ,etc.)and ILs(conventional ILs,functionalized ILs,etc.)are summarized.Moreover,research progresses on CO_(2)separation are also introduced focusing mainly on amines and ILs-based membranes(e.g.supported amines membranes,SILMs).Futhermore,the fixation of CO_(2)into cyclic carbonates catalyzed by ILs(pure ILs,complex catalyst system with ILs,supported ILs,etc.)is summarized,clearly explaining the mechanism of CO_(2)fixation with ILs.Finally,exploration of some recent studies about CO_(2)capture and conversion by ILs and challenges for further progress are presented and related suggestions are put forward. | Yuxin Wu Jianhong Xu Kathryn Mumford Geoffrey W.Stevens Weiyang Fei Yundong Wang | 2020 | Green Chemical Engineering2020，1，1： | 9 |
