1Materials discovery and design using machine learning显示文摘The screening of novel materials with good performance and the modelling of quantitative structureactivity relationships(QSARs),among other issues,are hot topics in the field of materials science.Traditional experiments and computational modelling often consume tremendous time and resources and are limited by their experimental conditions and theoretical foundations.Thus,it is imperative to develop a new method of accelerating the discovery and design process for novel materials.Recently,materials discovery and design using machine learning have been receiving increasing attention and have achieved great improvements in both time efficiency and prediction accuracy.In this review,we first outline the typical mode of and basic procedures for applying machine learning in materials science,and we classify and compare the main algorithms.Then,the current research status is reviewed with regard to applications of machine learning in material property prediction,in new materials discovery and for other purposes.Finally,we discuss problems related to machine learning in materials science,propose possible solutions,and forecast potential directions of future research.By directly combining computational studies with experiments,we hope to provide insight into the parameters that affect the properties of materials,thereby enabling more efficient and target-oriented research on materials discovery and design.Yue Liu Tianlu Zhao Wangwei Ju Siqi Shi 2017Journal of Materiomics2017,3,3:61

8Spatial and temporal variations of forest LAI in China during 2000-2010显示文摘Forests are crucial terrestrial ecosystems.Their leaf area index (LAI) is a key parameter determining the exchange of matter and energy between the atmosphere and the ground surface.In this study,MOD 09A1 and MCD 43A1 data were input into an inversion model based on the 4-scale geometric optical model to retrieve 8-d 500 m LAI products in China during the period 2000 to 2010.The resulting LAI product was validated using LAI measured in 6 typical areas.The spatial and temporal variations of forest LAI and its relationships with temperature and precipitation were analyzed.The results show that the accuracy of the 500 m LAI product was above 70% in the 6 typical areas,indicating the reliability of this product.From 2000 to 2010,forest LAI in northeast,north,and south central China showed increasing trends.However,forest LAI in southeast and parts of southwest China showed downward trends,mainly because of the significant decrease observed during the period 2008 to 2010.Annual mean forest LAI positively correlated with annual mean temperature (AMT) in northeastern China and negatively correlated with AMT in southwest China.It had positive correlations with annual total precipitation in central south and north China.The abnormal climate conditions in 2001 and 2009 caused forest LAI to be obviously lower than normal in regions south of the Qinling Mountains and Huaihe River.Annual mean LAI decreased by more than 1.0 in some areas.LIU YiBo JU WeiMin CHEN JingMing ZHU GaoLong XING BaiLing ZHU JingFang HE MingZhu 2012Chinese Science Bulletin2012,57,22:22
9Grain yield and water use efficiency of super rice under soil water deficit and alternate wetting and drying irrigation显示文摘This study investigated if super rice could better cope with soil water deficit and if it could have better yield performance and water use efficiency(WUE) under alternate wetting and drying(AWD) irrigation than check rice. Two super rice cultivars and two elite check rice cultivars were grown in pots with three soil moisture levels, well watered(WW), moderate water deficit(MWD) and severe water deficit(SWD). Two cultivars, each for super rice and check rice, were grown in field with three irrigation regimes, alternate wetting and moderate drying(AWMD), alternate wetting and severe drying(AWSD) and conventional irrigation(CI). Compared with that under WW, grain yield was significantly decreased under MWD and SWD treatments, with less reduction for super rice than for check rice. Super rice had higher percentage of productive tillers, deeper root distribution, higher root oxidation activity, and greater aboveground biomass production at mid and late growth stages than check rice, especially under WMD and WSD. Compared with CI, AWMD increased, whereas AWSD decreased grain yield, with more increase or less decrease for super rice than for check rice. Both MWD and SWD treatments and either AWMD or AWSD regime significantly increased WUE compared with WW treatment or CI regime, with more increase for super rice than for check rice. The results suggest that super rice has a stronger ability to cope with soil water deficit and holds greater promising to increase both grain yield and WUE by adoption of moderate AWD irrigation.ZHOU Qun JU Cheng-xin WANG Zhi-qin ZHANG Hao LIU Li-jun YANG Jian-chang ZHANG Jian-hua 2017Journal of Integrative Agriculture2017,16,5:22
10Exosomes from Suxiao Jiuxin pill-treated cardiac mesenchymal stem cells decrease H3K27 demethylase UTX expression in mouse cardiomyocytes in vitro显示文摘Suxiao Jiuxin 药片(SJP ) 是为在中国的急性冠的症候群的处理的繁体中文药,它包含二个主要部件, tetramethylpyrazine (TMP ) 和龙脑(BOR ) 。因此远然而,在心脏的微型环境上位于 SJP 的有益的效果下面的分子的机制是未知的。心脏的间充质的干细胞(C-MSCs ) 通过 microvesicles (exosomes ) 的版本与 cardiomyocytes (厘米) 交流恢复心脏的动态平衡并且得到修理,部分地通过 epigenetic 规章的机制。在这研究,我们检验了 SJP 处理是否改变了 C-MSC-derived exosomes (SJP-Exos ) 引起 epigenetic 在接受者厘米的色彩的改变。从老鼠心孤立的 C-MSC 是有 SJP (SJP-Exos ) 的 pretreated, TMP (TMP-Exos ) 或 BOR (BOR-Exos ) 。然后, HL-1 房间,一根鼠标 cardiomyocyte 线,从控制与 exosomes 被对待 C-MSCs (Ctrl-Exos ) , SJP-Exos, TMP-Exos 或 BOR-Exos。有 SJP-Exos 的处理显著地增加了 histone 的蛋白质层次 3 离氨酸 27 trimethylation (H3K27me3 ) ,为心脏的 transcriptional 抑制的一个关键 epigenetic 染色质标记,在 HL-1 房间。为了推进,探索 SJP-Exo-mediated H3K27me3 upregulation 的机制,我们在对待 exosome 的 HL-1 房间估计了关键 histone methylases (EZH1, EZH2 和 EED ) 和 demethylases (JMJD3 和 UTX ) 的 mRNA 表示层次。有 SJP-Exo 的处理有选择地在接受者 HL-1 房间压制了 UTX 表示。而且, PCNA,房间复制的一个内长的标记,比在 Ctrl-Exo-treated HL-1 房间在 SJP-Exo-treated HL-1 房间是显著地更高的。这些结果证明 SJP-Exos 增加 cardiomyocyte 增长并且证明 SJP 能调制 C-MSC-derived exosomes 引起 epigenetic 染色质在接受者 cardiomyocytes 改变;因而, SJP-Exos 可能被用来支持 cardiomyocyte 增长。Xiao-fen RUAN Yongdun LI Cheng-wei JU Yan SHEN Wei LEI Can CHEN Yang LI Hong YU Yu-tao LIU II-man KIM Xiao-long WANG Neal L WEINTRAUB Yaoliang TANG 2018Acta Pharmacologica Sinica2018,39,4:23

12Management of cytokine release syndrome related to CAR-T cell therapy显示文摘Chimeric antigen receptor T (CAR-T) cell therapy is a novel cellular immunotherapy that is widely used to treat hematological malignancies, including acute leukemia, lymphoma, and multiple myeloma. Despite its remarkable clinical effects, this therapy has side effects that cannot be underestimated. Cytokine release syndrome (CRS) is one of the most clinically important and potentially life-threatening toxicities. This syndrome is a systemic immune storm that involves the mass cytokines releasing by activated immune cells. This phenomenon causes multisystem damages and sometimes even death. In this study, we reported the management of a patient with recurrent and refractory multiple myeloma and three patients with acute lymphocytic leukemia who suffered CRS during CAR-T treatment. The early application of tocilizumab, an anti-IL-6 receptor antibody, according to toxicity grading and clinical manifestation is recommended especially for patients who suffer continuous hyperpyrexia, hypotensive shock, acute respiratory failure, and whose CRS toxicities deteriorated rapidly. Moreover, low doses of dexamethasone (5-10 mg/day) were used for refractory CRS not responding to tocilizumab. The effective management of the toxicities associated with CRS will bring additional survival opportunities and improve the quality of life for patients with cancer.Hongli Chen Fangxia Wang Pengyu Zhang Yilin Zhang Yinxia Chen Xiaohu Fan Xingmei Cao Jie Liu Yun Yang Baiyan Wang Bo Lei Liufang Gu Ju Bai Lili Wei Ruili Zhang Qiuchuan Zhuang Wanggang Zhang Wanhong Zhao Aili He 2019Frontiers of Medicine2019,13,5:21
13Numerical simulation for the coupling effect of local atmospheric circulations over the area of Beijing,Tianjin and Hebei Province显示文摘Using the model system MM5.V3 and multi-layer grid nesting technique, we have done a multi-scale numerical simulation over the area of Beijing, Tianjin and Hebei Province to analyze the temperature and wind field there and study its local circulations. The results show a coupling effect of Urban Heat Island Circulation (UHIC), Mountain Valley Breeze (MVB) and Sea Land Breeze (SLB) occurs in this area when the synoptic system is weak. The SLB can penetrate deep into the mainland for about 200 km when it is blooming. MVB can extend to south and cover almost the whole plain area in Beijing. Both MVB and SLB are diurnal periodical; meanwhile the phase of MVB drops behind that of SLB for about six hours. As a local circulation, the UHIC weakens the two circulations above, and it also has a diurnal period. As a result, the coupling effect of circulations reveals not only different features in spring-summer period and autumn-winter period in a year but also the difference between early morn- ing to noonday and afternoon to night in a day. We noted the diffusion of contamination over the area around Beijing, and found the steady presence of a transport routine of contamination over North-China throughout the year caused by the Coupling Effect mentioned above. This find is important for studying the environment pollution in this area.LIU ShuHua LIU ZhenXin LI Ju WANG YinChun MA YanJun SHENG Li LIU HePing LIANG FuMing XIN GuoJun WANG JianHua 2009Science China Earth Sciences2009,52,3:20

16Blockade of Tim-3 Pathway Ameliorates Interferon-γ Production from Hepatic CD8^+ T Cells in a Mouse Model of Hepatitis B Virus Infection显示文摘T cell immunoglobulin-and mucin-domain-containing molecule-3(Tim-3) has been reported to participate in the pathogenesis of inflammatory diseases. However,whether Tim-3 is involved in hepatitis B virus(HBV) infection remains unknown. Here,we studied the expression and function of Tim-3 in a hydrodynamics-based mouse model of HBV infection. A significant increase of Tim-3 expression on hepatic T lymphocytes,especially on CD8+ T cells,was demonstrated in HBV model mice from day 7 to day 18. After Tim-3 knockdown by specific shRNAs,significantly increased IFN-γ production from hepatic CD8+ T cells in HBV model mice was observed. Very interestingly,we found Tim-3 expression on CD8+ T cells was higher in HBV model mice with higher serum anti-HBs production. Moreover,Tim-3 knockdown influenced anti-HBs production in vivo. Collectively,our data suggested that Tim-3 might act as a potent regulator of antiviral T-cell responses in HBV infection.Ying Ju Nan Hou Xiaoning Zhang Di Zhao Ying Liu Jinjin Wang Fang Luan Wei Shi Faliang Zhu Wensheng Sun Lining Zhang Chengjiang Gao Lifen Gao Xiaohong Liang Chunhong Ma 2009Cellular & Molecular Immunology2009,6,1:19

18Research on in-situ condition preserved coring and testing systems显示文摘As shallow resources are increasingly depleted,the mechanics'theory and testing technology of deep insitu rock has become urgent.Traditional coring technologies obtain rock samples without retaining the in-situ environmental conditions,leading to distortion of the measured parameters.Herein,a coring and testing systems retaining in-situ geological conditions is presented:the coring system that obtains in-situ rock samples,and the transfer and testing system that stores and analyzes the rocks under a reconstructed environment.The ICP-Coring system mainly consists of the pressure controller,active insulated core reactor and insulation layer and sealing film.The ultimate bearing strength of 100 MPa for pressurepreservation,temperature control accuracy of 0.97%for temperature-retained are realized.CH_(4)and CO permeability of the optimized sealing film are as low as 3.85 and 0.33 ppm/min.The average tensile elongation of the film is 152.4%and the light transmittance is reduced to 0%.Additionally,the pressure and steady-state temperature accuracy for reconstructing the in-situ environment of transfer and storage system up to 1%and±0.2 is achieved.The error recorded of the noncontact sensor ring made of lowdensity polymer is less than 6%than that of the contact test.The system can provide technical support for the deep in-situ rock mechanics research,improving deep resource acquisition capabilities and further clarifying deep-earth processes.He-Ping Xie Tao Liu Ming-Zhong Gao Ling Chen Hong-Wei Zhou Yang Ju Feng Gao Xiao-Bo Peng Xiong-Jun Li Rui-Dong Peng Ya-Nan Gao Cong Li Zhi-Qiang He Ming-Qing Yang Zhi-Yu Zhao 2021Petroleum Science2021,18,6:19
19Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China.ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang 2014Biomedical and Environmental Sciences2014,27,5:17
20Consensus on the application of negative pressure wound therapy of diabetic foot wounds显示文摘Because China is becoming an aging society,the incidence of diabetes and diabetic foot have been increasing.Diabetic foot has become one of the main health-related killers due to its high disability and mortality rates.Negative pressure wound therapy(NPWT)is one of the most effective techniques for the treatment of diabetic foot wounds and great progress,both in terms of research and its clinical application,has been made in the last 20 years of its development.However,due to the complex pathogenesis and management of diabetic foot,irregular application of NPWT often leads to complications,such as infection,bleeding and necrosis,that seriously affect its treatment outcomes.In 2020,under the leadership of Burns,Trauma and Tissue Repair Committee of the Cross-Straits Medicine Exchange Association,the writing group for‘Consensus on the application of negative pressure wound therapy of diabetic foot wounds’was established with the participation of scholars from the specialized areas of burns,endocrinology,vascular surgery,orthopedics and wound repair.Drawing on evidence-based practice suggested by the latest clinical research,this consensus proposes the best clinical practice guidelines for the application and prognostic evaluation of NPWT for diabetic foot.The consensus aims to support the formation of standardized treatment schemes that clinicians can refer to when treating cases of diabetic foot.Shizhao Ji Xiaobin Liu Jie Huang Junmin Bao Zhaohong Chen Chunmao Han Daifeng Hao Jingsong Hong Dahai Hu Yufeng Jiang Shang Ju Hongye Li Zongyu Li Guangping Liang Yan Liu Gaoxing Luo Guozhong Lv Xingwu Ran Zhongmin Shi Juyu Tang Aiping Wang Guangyi Wang Jiangning Wang Xin Wang Bing Wen Jun Wu Hailin Xu Maojin Xu Xiaofei Ye Liangxi Yuan Yi Zhang Shichu Xiao Zhaofan Xia 2021Burns & Trauma2021,9,1:17
