| 1 | Altered trends in carbon uptake in China’s terrestrial ecosystems under the enhanced summer monsoon and warming hiatus显示文摘The carbon budgets in terrestrial ecosystems in China are strongly coupled with climate changes.Over the past decade,China has experienced dramatic climate changes characterized by enhanced summer monsoon and decelerated warming.However,the changes in the trends of terrestrial net ecosystem production(NEP)in China under climate changes are not well documented.Here,we used three ecosystem models to simulate the spatiotemporal variations in China's NEP during 1982–2010 and quantify the contribution of the strengthened summer monsoon and warming hiatus to the NEP variations in four distinct climatic regions of the country.Our results revealed a decadal-scale shift in NEP from a downtrend of–5.95 Tg C/yr^2(reduced sink)during 1982–2000 to an uptrend of 14.22 Tg C/yr^2(enhanced sink)during 2000–10.This shift was essentially induced by the strengthened summer monsoon,which stimulated carbon uptake,and the warming hiatus,which lessened the decrease in the NEP trend.Compared to the contribution of 56.3%by the climate effect,atmospheric CO2 concentration and nitrogen deposition had relatively small contributions(8.6 and 11.3%,respectively)to the shift.In conclusion,within the context of the global-warming hiatus,the strengthening of the summer monsoon is a critical climate factor that enhances carbon uptake in China due to the asymmetric response of photosynthesis and respiration.Our study not only revealed the shift in ecosystem carbon sequestration in China in recent decades,but also provides some insight for understanding ecosystem carbon dynamics in other monsoonal areas. | Honglin He Shaoqiang Wang Li Zhang Junbang Wang Xiaoli Ren Lei Zhou Shilong Piao Hao Yan Weimin Ju Fengxue Gu Shiyong Yu Yuanhe Yang Miaomiao Wang Zhongen Niu Rcmg Ge Huimin Yan Mei Huang Guoyi Zhou Yongfei Bai Zongqiang Xie Zhiyao Tang Bingfang Wu Leiming Zhang Nianpeng He Qiufeng Wang Guirui Yu | 2019 | National Science Review2019,6,3: | 24 |
| 2 | Climate 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 | 2019 | National Science Review2019,6,4: | 21 |
| 3 | Amplitude-Integrated Electroencephalography Predicts Outcome in Patients with Coma After Acute Brain Injury显示文摘Prognostication of coma patients after brain injury is important, yet challenging. In this study, we evaluated the predictive value of amplitude-integrated electroencephalography(a EEG) for neurological outcomes in coma patients. From January 2013 to January 2016, 128 coma patients after acute brain injury were prospectively enrolled and monitored with a EEG. The 6-month neurological outcome was evaluated using the Cerebral Performance Category Scale. a EEG monitoring commenced at a median of 7.5 days after coma onset. Continuous normal voltage predicted a good 6-month neurological outcome with a sensitivity of 93.6% and specificity of 85.2%. In contrast, continuous extremely low voltage, burst-suppression, or a flat tracing was correlated with poor 6-month neurological outcome with a sensitivity of 76.5% and specificity of 100%. In conclusion, a EEG is a promising predictor of 6-month neurological outcome for coma patients after acute brain injury. | Wendong You Qilin Tang Xiang Wu Junfeng Feng Qing Mao Guoyi Gao Jiyao Jiang | 2018 | Neuroscience Bulletin2018,34,4: | 15 |
| 4 | Comprehensive Proteomic Profiling of Patients'Tears Identifies Potential Biomarkers for the Traumatic Vegetative State显示文摘The vegetative state is a complex condition with unclear mechanisms and limited diagnostic, prognostic,and therapeutic methods. In this study, we aimed to explore the proteomic profile of tears from patients in a traumatic vegetative state and identify potential diagnostic markers using tears—a body fluid that can be collected noninvasively. Using i TRAQ quantitative proteomic technology, in the discovery phase, tear samples collected from 16 patients in a traumatic vegetative state and 16 normal individuals were analyzed. Among 1080 identified tear proteins, 57 were upregulated and 15 were downregulated in the patients compared to the controls. Bioinformatics analysis revealed that the differentially-expressed proteins were mainly involved in the wound response and immune response signaling pathways. Furthermore, we verified the levels of 7 differentially-expressed proteins in tears from50 traumatic vegetative state patients and 50 normal controls(including the samples used in the discovery phase) using ELISA. The results showed that this 7-protein panel had a high discrimination ability for traumatic vegetative state(area under the curve = 0.999). In summary, the altered tear proteomic profile identified in this study provides a basis for potential tear protein markers for diagnosis and prognosis of the traumatic vegetative state and also provides novel insights into the mechanisms of traumatic vegetative state. | Qilin Tang Chao Zhang Xiang Wu Wenbin Duan Weiji Weng Junfeng Feng Qing Mao Shubin Chen Jiyao Jiang Guoyi Gao | 2018 | Neuroscience Bulletin2018,34,4: | 3 |
| 5 | GRAIN COARSENING BEHAVIOR OF V-Ti-N MICROALLOYED STEELS显示文摘The effects of chemical composition and cooling rate after solidication on the grain coarseningtemperature,TGC,of the V-Ti-N microalloyed steels have been investigated.It is shownthat the TGC may be obviously raised by adding even a little Ti to the base steel so as to pre-cipitate a great deal of fine Ti-bearing particles of about 10 nm.The TGC does not increasewith the cooling rate,as it is over a certain critical value.The TGC is insensitive to any varia-tion of N content at simulated cooling condition of 150 mm continuous cast slab.TheTGC may be dropped down about 100℃ by adding 0.33 wt-%Mo to the steels.The sensitivi-ty of TGC to cooling condition relates to the Ti and V contents. | TANG Guoyi ZHENG Yangzeng Yanshan University,Qinhuangdao,ChinaCAI Qigong,ZHU Jing Central Iron and Steel Research Institute,Ministry of Metallurgical Industry,Beijing,China TANG Guoyi,Dept.of Graduates,Central Iron and Steel Research Institute,Ministry of Metallurgical Industry,Beijing 100081,China | 1990 | Acta Metallurgica Sinica(English Letters)1990,3,3: | 3 |
| 6 | Effect of Electropulsing on Recrystallization and Mechanical Properties of Silicon Steel Strips显示文摘Electropulsing-induced recrystallization and its effect on mechanical properties of oriented silicon steel strips (Fe-3.0%Si) were studied by optical microscopy, scanning electron microscopy and electron back-scatter diffraction. The results indicated that electropulsing accelerated recrystallization, and decreased the temperature of recrystallization. Electropulsing favors refinement of the grain structure of the alloy. Effects of electropulsing on strength and elongation of the alloy were discussed from the point view of dislocation dynamics, microstructural changes, and electropulsing kinetics. | Guoliang Hu Yaohua Zhu Guoyi Tang Chanhung Shek Iianan Liu | 2011 | Journal of Materials Science & Technology2011,27,11: | 3 |

| 8 | Tumor-targeted delivery of siRNA to silence Sox2 gene expression enhances therapeutic response in hepatocellular carcinoma显示文摘RNA interference(RNAi)is one of the most promising methods for the treatment of malignant tumors.However,developing an efficient biocompatible delivery vector for small interfering RNA(siRNA)remains a challenging issue.This study aimed to prepare a non-viral tumor-targeted carrier,named RGDfC-modified functionalized selenium nanoparticles(RGDfC-SeNPs).RGDfC-SeNPs were used to selectively deliver siSox2 to HepG2 liver cancer cells and tissues for the treatment of hepatocellular carcinoma(HCC).In the current study,RGDfC-SeNPs were successfully synthesized and characterized.It was shown that RGDfC-SeNPs could effectively load siSox2 to prepare an antitumor prodrug RGDfC-Se@siSox2.RGDfC-Se@siSox2 exhibited selective uptake in HepG2 liver cancer cells and LO2 normal liver cells,indicating RGDfC-SeNPs could effectively deliver siSox2 to HepG2 liver cancer cells.RGDfC-Se@siSox2 entered HepG2 cells via clathrin-mediated endocytosis by firstly encircling the cytoplasm and then releasing siSox2 in the lysosomes.RGDfC-Se@siSox2 could effectively silence Sox2 and inhibit the proliferation,migration and invasion of HepG2 cells.RGDfC-Se@siSox2 induced HepG2 cells apoptosis most likely via overproduction of reactive oxygen species and disruption of the mitochondrial membrane potentials.Most importantly,RGDfC-Se@siSox2 significantly inhibited the tumor growth in HepG2 tumor-bearing mice without obvious toxic side effects.These studies indicated that RGDfC-SeNPs may be an ideal gene carrier for delivering siSox2 to HepG2 cells and that RGDfC-Se@siSox2 may be a novel and highly specific gene-targeted prodrug therapy for HCC. | Yu Xia Guoyi Tang Yi Chen Changbing Wang Min Guo Tiantian Xu Mingqi Zhao Yongjian Zhou | 2021 | Bioactive Materials2021,6,5: | 2 |
| 9 | Research on Retained Austenite for Advanced Aluminum-containing Hot-rolled TRIP Steel显示文摘A new type of hot-rolled transformation induced plasticity (TRIP) steel with 2.3%AI was developed to replaceconventional Si-bearing TRIP steel to improve surface quality of the steel sheet. The relationship between retainedaustenite volume fraction and hot-rolling processing was researched by Gleeble-2000 thermo-dynamic test for theAl-bearing steel. The experimental result showed that aluminum played an important role on retaining austeniteand the volume fraction increased from 4.4% to 7.5% as coiling temperature increased from 350°C to 450°C, whilecoiling temperature had a stronger effect on retaining austenite than finishing rolling temperature. | Yu CHEN Guoyi TANG Fangyu CHEN Pinghe LI Sunbing ZHOU | 2005 | Journal of Materials Science & Technology2005,21,6: | 2 |

| 11 | Two Ultraviolet Radiation Datasets that Cover China显示文摘Ultraviolet(UV) radiation has significant effects on ecosystems, environments, and human health, as well as atmospheric processes and climate change. Two ultraviolet radiation datasets are described in this paper. One contains hourly observations of UV radiation measured at 40 Chinese Ecosystem Research Network stations from 2005 to 2015. CUV3 broadband radiometers were used to observe the UV radiation, with an accuracy of 5%, which meets the World Meteorology Organization's measurement standards. The extremum method was used to control the quality of the measured datasets. The other dataset contains daily cumulative UV radiation estimates that were calculated using an all-sky estimation model combined with a hybrid model. The reconstructed daily UV radiation data span from 1961 to 2014. The mean absolute bias error and root-mean-square error are smaller than 30% at most stations, and most of the mean bias error values are negative, which indicates underestimation of the UV radiation intensity. These datasets can improve our basic knowledge of the spatial and temporal variations in UV radiation. Additionally, these datasets can be used in studies of potential ozone formation and atmospheric oxidation, as well as simulations of ecological processes. | Hui LIU Bo HU Yuesi WANG Guangren LIU Liqin TANG Dongsheng JI Yongfei BAI Weikai BAO Xin CHEN Yunming CHEN Weixin DING Xiaozeng HAN Fei HE Hui HUANG Zhenying HUANG Xinrong LI Yan LI Wenzhao LIU Luxiang LIN Zhu OUYANG Boqiang QIN Weijun SHEN Yanjun SHEN Hongxin SU Changchun SONG Bo SUN Song SUN Anzhi WANG Genxu WANG Huimin WANG Silong WANG Youshao WANG Wenxue WEI Ping XIE Zongqiang XIE Xiaoyuan YAN Fanjiang ZENG Fawei ZHANG Yangjian ZHANG Yiping ZHANG Chengyi ZHAO Wenzhi ZHAO Xueyong ZHAO Guoyi ZHOU Bo ZHU | 2017 | Advances in Atmospheric Sciences2017,34,7: | 2 |
| 12 | PIWIL1 governs the crosstalk of cancer cell metabolism and immunosuppressive microenvironment in hepatocellular carcinoma显示文摘Altered energy metabolism of cancer cells shapes the immune cell response in the tumor microenvironment that faclitates tumorprogression.Herein,we reported the novel of tumor cell-expressed Piwi Like RNA-Mediated Gene Silencing 1(PWL1)in mediatingthe crosstlk of fatty acid metabolism and immune response of human hepatocellular carcinoma(HCC).PlWIL1 expression in HCCwas increased compared to normal hepatic tissues and was positively correlated with the proliferation rate of HCC cell ines.PIWL1overexpression accelerated in vitro proliferation and in vivo growth of HCC tumors,while PIWL1 knockdown showed opositeeffects.PIWL1 increased oxygen consumption and energy production via fatty acid metabolism without altering aerobic glycolysis.lnhibition of fatty acid metablism abolished PWIL1-induced HCC prolferation and growth.RNA-seq analysis revealed that immunesystem regulation might be involved,which was echoed by the experimental observation that PIWL1-overexpressing HCC cellsattracted myeloid-derived suppressor cells(MDSCs)into the tumor microenvironment.MDSCs depletion reduced the prolferationand growth of PlWIL1-overexpressing HCC tumors.Complement C3,whose secretion was induced by PIWL1 in HCC cells,mediatesthe interaction of HCC cells with MDSCs by activated p38 MAPK signaling in MDSCs,which in turn initiated expression of immunosuppressive cytokine L10.Neutralizing lL10 secretion reduced the immunosuppressive activity of MDSCs in the microenvironment of PIWL1-overexpressing HCC.Taken together,our study unraveled the critical role of PIWL1 in initiating theinteraction of cancer cell metabolism and immune cell response in HCC.Tumor cell-expressed PlIWL1 may be a potential target forthe devellopment of novel HCC treatment. | Ning Wang Hor-Yue Tan Yuanjun Lu Yau-Tuen Chan Di Wang Wei Guo Yu Xu Cheng Zhang Feiyu Chen Guoyi Tang Yibin Feng | 2021 | Signal Transduction and Targeted Therapy2021,6,3: | 2 |
