1单窗算法的大气参数估计方法显示文摘根据地表热辐射传导方程,提出了一个简单可行且精度较高的专门用于从TM6数据中演算地表温度的方法———单窗算法。这一算法把大气和地表状态对地表热传导的影响直接包括在演算公式中。该方法需要两个大气参数进行地表温度的演算,即大气平均作用温度和大气透射率。本文论述这两个大气参数的估计方法:根据大气水分含量或地表附近空气湿度来估计大气透射率;通过分析标准大气剖面资料,尤其是大气水分和气温随高程的变化规律,根据地表温度推算大气平均作用温度。覃志豪 LI Wenjuan ZHANG Minghua Arnon Karnieli Pedro Berliner 2003国土资源遥感2003,15,2:352

3Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)显示文摘In recent years,as living standards have continued to improve,the number of diabetes patients in China,along with the incidence of complications associated with the disease,has been increasing.Among these complications,diabetic foot disease is one of the main causes of disability and death in diabetic patients.Due to the differences in economy,culture,religion and level of medical care available across different regions,preventive and treatment methods and curative results for diabetic foot vary greatly.In multidisciplinary models built around diabetic foot,the timely assessment and diagnosis of wounds and appropriate methods of prevention and treatment with internal and external surgery are key to clinical practice for this pathology.In 2019,under the leadership of the Jiangsu Medical Association and Chinese Diabetes Society,the writing group for the Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)was established with the participation of scholars from the specialist areas of endocrinology,burn injury,vascular surgery,orthopedics,foot and ankle surgery and cardiology.Drawing lessons from diabetic foot guidelines from other countries,this guide analyses clinical practices for diabetic foot,queries the theoretical basis and grades and gives recommendations based on the characteristics of the pathology in China.This paper begins with assessments and diagnoses of diabetic foot,then describes treatments for diabetic foot in detail,and ends with protections for high-risk feet and the prevention of ulcers.This manuscript covers the disciplines of internal medicine,surgical,nursing and rehabilitation and describes a total of 50 recommendations that we hope will provide procedures and protocols for clinicians dealing with diabetic foot.Aiping Wang Guozhong Lv Xingbo Cheng Xianghua Ma Wei Wang Jianchao Gui JiHu Meng Lu Guoping Chu Jin’an Chen Hao Zhang Yiqiu Jiang Yuedong Chen Wengbo Yang Lin Jiang Houfa Geng Rendong Zheng Yihui Li Wei Feng Boey Johnson Wenjuan Wang Dalong Zhu Yin Hu 2020Burns & Trauma2020,8,1:34

5pORF5 plasmid protein of Chlamydia trachomatis induces MAPK-mediated pro-inflammatory cytokines via TLR2 activation in THP-1 cells显示文摘Infection with Chlamydia trachomatis induces inflammatory pathologies in the urogenital tract that can lead to infertility and ectopic pregnancy.Pathogenesis of infection has been mostly attributed to excessive cytokine production.However,precise mechanisms on how C.trachomatis triggers this production,and which protein(s) stimulate inflammatory cytokines remains unknown.In the present study,the C.trachomatis pORF5 protein induced tumor necrosis factor alpha(TNF-α),interleukin-1 beta(IL-1β) and interleukin-8(IL-8) in dose-and time-dependent manners in the THP-1 human monocyte cell line.We found that intracellular p38/mitogen-activated protein kinase(MAPK) and extracellular signal-regulated kinase(ERK)/MAPK signaling pathways were required for the induction of TNF-α,IL-1β and IL-8.Blockade of toll-like receptor 2(TLR2) signaling reduced induction levels of TNF-α,IL-8 and IL-1β.We concluded that the C.trachomatis pORF5 protein might contribute to the inflammatory processes associated with chlamydial infections.ZHOU Hui HUANG QiuLin LI ZhongYu WU YiMou XIE XiaoBing MA KangKang CAO WenJuan ZHOU Zhou LU ChunXue ZHONG GuangMing 2013Science China(Life Sciences)2013,56,5:26
6Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration.Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen 2019National Science Review2019,6,4:21
7Molecular evolution and functional divergence of HAK potassium transporter gene family in rice(Oryza sativa L.)显示文摘The high-affinity K+(HAK) transporter gene family is the largest family in plant that functions as potassium transporter and is impor-tant for various aspects of plant life.In the present study,we identified 27 members of this family in rice genome.The phylogenetic tree divided the land plant HAK transporter proteins into 6 distinct groups.Although the main characteristic of this family was established before the origin of seed plants,they also showed some differences between the members of non-seed and seed plants.The HAK genes in rice were found to have expanded in lineage-specific manner after the split of monocots and dicots,and both segmental duplication events and tandem duplication events contributed to the expansion of this family.Functional divergence analysis for this family provided statis-tical evidence for shifted evolutionary rate after gene duplication.Further analysis indicated that both point mutant with positive selection and gene conversion events contributed to the evolution of this family in rice.Zefeng Yang Qingsong Gao Changsen Sun Wenjuan Li Shiliang Gu Chenwu Xu 2009Journal of Genetics and Genomics2009,36,3:21

9Global Dynamic Modeling of Electro-Hydraulic 3-UPS/S Parallel Stabilized Platform by Bond Graph显示文摘Dynamic modeling of a parallel manipulator(PM) is an important issue. A complete PM system is actually composed of multiple physical domains. As PMs are widely used in various fields, the importance of modeling the global dynamic model of the PM system becomes increasingly prominent. Currently there lacks further research in global dynamic modeling. A unified modeling approach for the multi-energy domains PM system is proposed based on bond graph and a global dynamic model of the 3-UPS/S parallel stabilized platform involving mechanical and electrical-hydraulic elements is built. Firstly, the screw bond graph theory is improved based on the screw theory, the modular joint model is modeled and the normalized dynamic model of the mechanism is established. Secondly, combined with the electro-hydraulic servo system model built by traditional bond graph, the global dynamic model of the system is obtained, and then the motion, force and power of any element can be obtained directly. Lastly, the experiments and simulations of the driving forces, pressure and flow are performed, and the results show that, the theoretical calculation results of the driving forces are in accord with the experimental ones, and the pressure and flow of the first limb and the third limb are symmetry with each other. The results are reasonable and verify the correctness and effectiveness of the model and the method. The proposed dynamic modeling method provides a reference for modeling of other multi-energy domains system which contains complex PM.ZHANG Lijie GUO Fei LI Yongquan LU Wenjuan 2016Chinese Journal of Mechanical Engineering2016,29,6:11
10Effects of short-term low temperatures on photosystem Ⅱ function of samara and leaf of Siberian maple (Acer ginnala) and subsequent recovery显示文摘Samara is the reproductive organ (seed) for many tree species in arid land in northwestern China. It is ecologically important in population development due to its dispersal function. However, information on its photosynthesis and effect of environmental stresses on its photosynthesis is still very limited. In the present study, responses of photosystem II (PSII) activity in samara and leaf of Siberian maple to short-term chilling/freezing and subsequent recovery potential were comparatively investigated by using polyphasic fluorescence test. The samara had more efficient photosynthesis (Fv/Fm and PIABS) and more efficient electron transport (φEo) but lower energy dissipation (DIo/RC) than leaf. Generally, the PSII performance and the electron transport for both samara and leaf were inhibited under low temperature stress, accompanied by an increase of energy dissipation in PSII reaction centers (RCs). PSII of both samara and leaf was not markedly affected by chilling and could acclimate to chilling stress. Short-term freezing could completely inhibit PSII activity in both samara and leaf, indicated by the drop of values of Fv/Fm, PIABS, φEo to zero. PSII functional parameters of short-term dark frozen samara could be largely recovered whereas those of frozen leaf could not be recovered. The higher tolerance of samara to short-term low temperature stress than leaf is of great ecological significance for seed development, population establishment of Siberian maple.XiangLiang PAN1, DaoYong ZHANG1,2, Xi CHEN1, Li LI1, GuiJin MU1, LanHai LI1, AnMing BAO1, Jing LIU2, HuaiSong ZHU1, WenJuan SONG1, JianYing YANG1, JunYong AI1 1 Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, Urumqi 830011, China 2 State Key Laboratory of Environmental Geochemistry, Institute of Geochemistry, Chinese Academy of Sciences, Guiyang 550000, China 2009Journal of Arid Land2009,1,1:10

12Remote Sensing Monitoring of Gullies on a Regional Scale: A Case Study of Kebai Region in Heilongjiang Province, China显示文摘Gully erosion is one of the major causes of land degradation in most areas and attracts increasing attention from researchers. We monitored gullies in the Kebai region in Heilongjiang Province of China by using remote sensing data and found that gully density increased with the increase in slope when the slope was less than 3°. Gully density in sunny slopes or windward slopes was greater than in shady slopes or leeward slopes because of the impacts of freezing and thawing, wind and solar radiation. Specifically, the gully density in northeast slope was the greatest and in southwest was the smallest. Gully density was reduced with increasing slope length and the longer the slope length, the less the gully density changed between 1965 and 2005. Affected by runoff, gullies most easily to occur in concave slopes and the critical elevation for gully erosion was 250–275 m. Moreover, hilly regions had the greatest gully density, followed by tableland regions, whereas the gully density in flatlands was the lowest. However, the gully density of these three types of landforms all increased between 1945 and 2000, and the portion of increase was 57.45%(hill), 52.91%(mesa) and 25.32%(plain), respectively.ZHANG Shuwen LI Fei LI Tianqi YANG Jiuchun BU Kun CHANG Liping WANG Wenjuan YAN Yechao 2015Chinese Geographical Science2015,25,5:10
13The effects of dietary fiber level on nutrient digestibility in growing pigs显示文摘The objective of this study was to investigate the effects of total dietary fiber level on nutrient digestibility and the relationship between apparent total tract digestibility of total dietary fiber, and soluble dietary fiber, insoluble dietary fiber and available energy. Sugar beet pulp was as the only fiber source. The experiment was designed as a 6×6 Latin square with an adaptation period of 7 d followed by a 5-d total collection of feces and urine. Feed intake tended to decrease(P=0.10) as total dietary fiber level increased. The apparent total tract digestibility of dry matter, crude protein and gross energy decreased(P<0.01) when total dietary fiber increased but the digestibility of soluble dietary fiber and insoluble dietary fiber increased(P<0.01). The digestible energy and metabolizable energy content of diets decreased(P<0.01) as the total dietary fiber increased.Wenjuan Zhang Defa Li Ling Liu Jianjun Zang Qiwu Duan Wenjun Yang Liying Zhang 2013Journal of Animal Science and Biotechnology2013,4,4:9
14Endothelial CDS2 deficiency causes VEGFA-mediated vascular regression and tumor inhibition显示文摘The response of endothelial cells to signaling stimulation is critical for vascular morphogenesis,homeostasis and function.Vascular endothelial growth factor-a(VEGFA)has been commonly recognized as a pro-angiogenic factor in vertebrate developmental,physiological and pathological conditions for decades.Here we report a novel finding that genetic ablation of CDP-diacylglycerol synthetase-2(CDS2),a metabolic enzyme that controls phosphoinositide recycling,switches the output of VEGFA signaling from promoting angiogenesis to unexpectedly inducing vessel regression.Live imaging analysis uncovered the presence of reverse migration of the angiogenic endothelium in cds2 mutant zebrafish upon VEGFA stimulation,and endothelium regression also occurred in postnatal retina and implanted tumor models in mice.In tumor models,CDS2 deficiency enhanced the level of tumorsecreted VEGFA,which in-turn trapped tumors into a VEGFA-induced vessel regression situation,leading to suppression of tumor growth.Mechanistically,VEGFA stimulation reduced phosphatidylinositol(4,5)-bisphosphate(PIP2)availability in the absence of CDS2-controlled-phosphoinositide metabolism,subsequently causing phosphatidylinositol(3,4,5)-triphosphate(PIP3)deficiency and F0X01 activation to trigger regression of CDS2-null endothelium.Thus,our data indicate that the effect of VEGFA on vasculature is context-dependent and can be converted from angiogenesis to vascular regression.Wencao Zhao Le Cao Hanru Ying Wenjuan Zhang Dantong Li Xiaolong Ziiu Wenzhi Xue Shuang Wu Mengye Cao Cong Fu Haonan Qi Yimei Hao Yun-Chi Tang Jun Qin Tao PZhong Xiaoxi Lin Luyang Yu Xuri Li Lin Li Dianqing Wu Weijun Pan 2019Cell Research2019,29,11:9
152D titanium carbide(MXene) electrodes with lower-F surface for high performance lithium-ion batteries显示文摘MXene has shown distinctive advantages as anode materials of lithium-ion batteries. However, local surface chemistry, which was confirmed that can block ion transfer and limit redox reaction, has a significant effect on electrochemical performance. Herein, annealing MXene under hydrogen was employed for removing-F and turning-OH to-O terminations. We demonstrate that it improves the kinetics of Li-ion transport between the electrolyte and electrode. As a result, a lower interfacial charge transfer impedance was obtained. The electrochemical measurement exhibited that a nearly 2-fold increase of specific capacity was achieved for the annealed MXene.Ming Lu Haojie Li Wenjuan Han Junnan Chen Wen Shi Jiaheng Wang Xiang-Min Meng Jingang Qi Haibo Li Bingsen Zhang Wei Zhang Weitao Zheng 2019Journal of Energy Chemistry2019,28,4:8
16THF_1 mutations lead to increased basal and wound-induced levels of oxylipins that stimulate anthocyanin biosynthesis via COI_1 signaling in Arabidopsis显示文摘Mutants defective in chloroplast development or photosynthesis are liable to accumulate higher levels of anthocyanin in photo-oxidative stress.However,regulatory mechanisms of anthocyanin biosynthesis in the mutants remain unclear.Here,we investigated the mechanism by which the deletion of thylakoid formation1(THF1) leads to an increased level of anthocyanin in Arabidopsis thaliana L.Physiological and genetic evidence showed that the increased level of anthocyanin in thf1 is dependent on coronatine-insensitive1(COM)signaling.Our data showed that thf1 had higher levels of basalα-linolenic acid(α-LeA),and methyl jasmonate(JA)-induced α-LeA and 12-oxophytodienoic acid(OPDA) than the wild type(WT).Consistently,expression levels of phospholipase genes including pPLAIIα and PLA-Iγ1 were elevated in thf1.Furthermore,inhibition of lipase activity by bromoenol lactone,a specific inhibitor of plant pPLA,led to producing identical levels of anthocyanins in WT and thf1 plants.Interestingly,OPDA biosynthesis was triggered by light illumination in isolated chloroplasts,indicating that new protein import into chloroplasts is not required for OPDA biosynthesis.Thus,we conclude that the elevated anthocyanin accumulation in thf1 is attributed to an increase in JA levels.This JA-mediated signaling to coordinate plant metabolism and growth in stress may be conserved in other photosensitive mutants.Yi Gan Hong Li Ye Xie Wenjuan Wu Maoyin Li Xuemin Wang Jirong Huang 2014Journal of Integrative Plant Biology2014,56,9:8

18TGIF2 promotes the progression of lung adenocarcinoma by bridging EGFR/RAS/ERK signaling to cancer cell stemness显示文摘TGF-β-induced factor homeobox 2(TGIF2)is a transcription regulator that plays essential roles in the regulation of development and cell fate decisions.Aberrant expression of TGIF family proteins has been observed in several cancers,including ovarian,esophageal,and colorectal cancers.Here,we report that TGIF2 mediates the EGFR–RAS–ERK signaling pathway to enhance the stemness of lung adenocarcinoma(LUAD)cells and,therefore,promote the progression and metastasis of LUAD.We found that high TGIF2 expression was closely correlated with tumor growth,lymph node metastasis,and survival of patients with LUAD.Mice bearing TGIF2-silenced H1299 xenografts developed smaller tumors and fewer lung metastases.Importantly,silencing TGIF2 decreased the cancer stem cell(CSC)-like properties in A549 and H1299 cells.Furthermore,we identified that TGIF2 binding to the OCT4 promoter promotes its expression.In both LUAD cells and in vivo LUAD mouse models,we revealed that EGFR–RAS–ERK signaling phosphorylated TGIF2 and increased its stability,which was important for TGIF2-promoted LUAD stemness since phosphorylation-deficient TGIF2 mutants lost these functions.Thus,our study revealed that an important factor,TGIF2,bridges EGFR signaling to the CSC characteristics of LUAD cells,which can be utilized as an effective target for LUAD therapy.Renle Du Wenzhi Shen Yi Liu Wenjuan Gao Wei Zhou Jun Li Shuangtao Zhao Chong Chen Yanan Chen Yanhua Liu Peiqing Sun Rong Xiang Yi Shi Yunping Luo 2019Signal Transduction and Targeted Therapy2019,4,1:7
19Removal of impurities from scandium chloride solution using 732-type resin显示文摘The deep removal of Al, Fe(Ⅱ/Ⅲ), Ca, Zr, Ti and Si from scandium chloride solution was carried out by using 732-type strong acid cation exchange resin. The effects of pH value, contact time and complexing agents(EDTA) on the purification process are investigated. The results indicate that the 732-type resin have a good scandium selectivity and the adsorption order is Sc > Fe(Ⅲ)>Al > Ca > Zr > Ti > Si in the pH range of 1-3. The separation of Sc and Zr, Si, Ti can be directly carried out because the resin have a good adsorption effect on Sc, AI and Fe(Ⅲ) but poor adsorption effect on Zr, Si and Ti under the condition of pH = 2.5 and contact time 180 min. The Fe(Ⅱ), Ca and Al are selectively adsorbed on the resin by adding reducing agent ascorbic acid and EDTA into the solution for reducing Fe(Ⅲ) to Fe(Ⅱ) and complexing Sc.By using two-step ion exchange adsorption separation method, the removal rates of Fe(Ⅲ), Ti, Al, Ca, Zr and Si are 95.5%,99.8%,100%,98.2%,98.6% and 100%,respectively.Guotao Zhou Qinggang Li Pan Sun Wenjuan Guan Guiqing Zhang Zuoying Cao Li Zeng 2018Journal of Rare Earths2018,36,3:7
