| 1 | Progresses on microwave remote sensing of land surface parameters显示文摘Highly accurate observations at various scales on the land surface are urgently needed for the studies of many areas,such as hydrology,meteorology,and agriculture.With the rapid development of remote sensing techniques,remote sensing has had the capacity of monitoring many factors of the Earth's land surface.Especially,the space-borne microwave remote sensing systems have been widely used in the quantitative monitoring of global snow,soil moisture,and vegetation parameters with their all-weather,all-time observation capabilities and their sensitivities to the characteristics of land surface factors.Based on the electromagnetic theories and microwave radiative transfer equations,researchers have achieved great successes in the microwave remote sensing studies for different sensors in recent years.This article has systematically reviewed the progresses on five research areas including microwave theoretical modeling,microwave inversion on soil moisture,snow,vegetation and land surface temperatures.Through the further enrichment of remote sensing datasets and the development of remote sensing theories and inversion techniques,remote sensing including microwave remote sensing will play a more important role in the studies and applications of the Earth systems. | SHI JianCheng DU Yang DU JinYang JIANG LingMei CHAI LinNa MAO KeBiao XU Peng NI WenJian XIONG Chuan LIU Qiang LIU ChenZhou GUO Peng CUI Qian LI YunQing CHEN Jing WANG AnQi LUO HeJia WANG YinHui | 2012 | Science China Earth Sciences2012,55,7: | 24 |
| 2 | Exogenous NADPH ameliorates myocardial ischemia–reperfusion injury in rats through activating AMPK/mTOR pathway显示文摘Our previous study shows that nicotinamide adenine dinucleotide phosphate(NADPH)plays an important role in protecting against cerebral ischemia injury.In this study we investigated whether NADPH exerted cardioprotection against myocardial ischemia/reperfusion(I/R)injury.To induce myocardial I/R injury,rats were subjected to ligation of the left anterior descending branch of coronary artery for 30 min followed by reperfusion for 2 h.At the onset of reperfusion,NADPH(4,8,16 mg·kg?1·d?1,iv)was administered to the rats.We found that NADPH concentrations in plasma and heart were signi?cantly increased at 4 h after intravenous administration.Exogenous NADPH(8?16 mg/kg)signi?cantly decreased myocardial infarct size and reduced serum levels of lactate dehydrogenase(LDH)and cardiac troponin I(cTn-I).Exogenous NADPH signi?cantly decreased the apoptotic rate of cardiomyocytes,and reduced the cleavage of PARP and caspase-3.In addition,exogenous NADPH reduced mitochondrial vacuolation and increased mitochondrial membrane protein COXIV and TOM20,decreased BNIP3L and increased Bcl-2 to protect mitochondrial function.We conducted in vitro experiments in neonatal rat cardiomyocytes(NRCM)subjected to oxygen–glucose deprivation/restoration(OGD/R).Pretreatment with NADPH(60,500 nM)signi?cantly rescued the cell viability and inhibited OGD/R-induced apoptosis.Pretreatment with NADPH signi?cantly increased the phosphorylation of AMPK and downregulated the phosphorylation of mTOR in OGD/R-treated NRCM.Compound C,an AMPK inhibitor,abolished NADPH-induced AMPK phosphorylation and cardioprotection in OGD/R-treated NRCM.In conclusion,exogenous NADPH exerts cardioprotection against myocardial I/R injury through the activation of AMPK/mTOR pathway and inhibiting mitochondrial damage and cardiomyocyte apoptosis.NADPH may be a potential candidate for the prevention and treatment of myocardial ischemic diseases. | Jiang Zhu Yi-fei Wang Xiao-ming Chai Ke Qian Ling-wei Zhang Peng Peng Pei-min Chen Jian-fang Cao Zheng-hong Qin Rui Sheng Hong Xie | 2020 | Acta Pharmacologica Sinica2020,41,4: | 19 |

| 7 | Study on the mechanism of copper-ammonia complex decomposition in struvite formation process and enhanced ammonia and copper removal显示文摘Heavy metals and ammonia are difficult to remove from wastewater,as they easily combine into refractory complexes.The struvite formation method(SFM) was applied for the complex decomposition and simultaneous removal of heavy metal and ammonia.The results indicated that ammonia deprivation by SFM was the key factor leading to the decomposition of the copper-ammonia complex ion.Ammonia was separated from solution as crystalline struvite,and the copper mainly co-precipitated as copper hydroxide together with struvite.Hydrogen bonding and electrostatic attraction were considered to be the main surface interactions between struvite and copper hydroxide.Hydrogen bonding was concluded to be the key factor leading to the co-precipitation.In addition,incorporation of copper ions into the struvite crystal also occurred during the treatment process. | Cong Peng Liyuan Chai Chongjian Tang Xiaobo Min Yuxia Song Chengshan Duan Cheng Yu | 2017 | Journal of Environmental Sciences2017,29,1: | 9 |
| 8 | A natural variation in Ribonuclease H-like gene underlies Rht8 to confer“Green Revolution”trait in wheat显示文摘Dear Editor,Introduction of gibberellin(GA)-insensitive Reduced height(Rht)genes,Rht-B1b and Rht-D1b,has resulted in the“Green Revolution”in modern wheat cultivars(Triticum aestivum)that has skyrocketed wheat grain yields worldwide since the 1960s(Peng et al.,1999;Velde et al.,2021).However,Rht-B1b/D1b also reduce coleoptiles,which is undesired in dryland regions where deep planting is essential for seedling establishment(Rebetzke et al.,1999,Rebetzke et al.,2001;Ellis et al.,2004). | Lingling Chai Mingming Xin Chaoqun Dong Zhaoyan Chen Huijie Zhai Junhong Zhuang Xuejiao Cheng Naijiao Wang Jia Geng Xiaobo Wang Ruolin Bian Yingyin Yao Weilong Guo Zhaorong Hu Huiru Peng Guihua Bai Qixin Sun Zhenqi Su Jie Liu Zhongfu Ni | 2022 | Molecular Plant2022,15,3: | 8 |
| 9 | Construction of heparin-based hydrogel incorporated with Cu_(5.4)O ultrasmall nanozymes for wound healing and inflammation inhibition显示文摘Excessive production of inflammatory chemokines and reactive oxygen species(ROS)can cause a feedback cycle of inflammation response that has a negative effect on cutaneous wound healing.The use of wound-dressing materials that simultaneously absorb chemokines and scavenge ROS constitutes a novel‘weeding and uprooting’treatment strategy for inflammatory conditions.In the present study,a composite hydrogel comprising an amine-functionalized star-shaped polyethylene glycol(starPEG)and heparin for chemokine sequestration as well as Cu_(5.4)O ultrasmall nanozymes for ROS scavenging(Cu_(5.4)O@Hep-PEG)was developed.The material effectively adsorbs the inflammatory chemokines monocyte chemoattractant protein-1 and interleukin-8,decreasing the migratory activity of macrophages and neutrophils.Furthermore,it scavenges the ROS in wound fluids to mitigate oxidative stress,and the sustained release of Cu_(5.4)O promotes angiogenesis.In acute wounds and impaired-healing wounds(diabetic wounds),Cu_(5.4)O@Hep-PEG hydrogels outperform the standard-of-care product Promogram®in terms of inflammation reduction,increased epidermis regeneration,vascularization,and wound closure. | Yuan Peng Danfeng He Xin Ge Yifei Lu Yuanhao Chai Yixin Zhang Zhengwei Mao Gaoxing Luo Jun Deng Yan Zhang | 2021 | Bioactive Materials2021,6,10: | 7 |
| 10 | Consensus on the digestive endoscopic tunnel technique显示文摘With the digestive endoscopic tunnel technique(DETT), many diseases that previously would have been treated by surgery are now endoscopically curable by establishing a submucosal tunnel between the mucosa and muscularis propria(MP). Through the tunnel, endoscopic diagnosis or treatment is performed for lesions in the mucosa, in the MP, and even outside the gastrointestinal(GI) tract.At present, the tunnel technique application range covers the following:(1)Treatment of lesions originating from the mucosal layer, e.g., endoscopic submucosal tunnel dissection for oesophageal large or circular early-stage cancer or precancerosis;(2) treatment of lesions from the MP layer, per-oral endoscopic myotomy, submucosal tunnelling endoscopic resection, etc.; and(3) diagnosis and treatment of lesions outside the GI tract, such as resection of lymph nodes and benign tumour excision in the mediastinum or abdominal cavity. With the increasing number of DETTs performed worldwide, endoscopic tunnel therapeutics, which is based on DETT, has been gradually developed and optimized. However, there is not yet an expert consensus on DETT to regulate its indications, contraindications, surgical procedure, and postoperative treatment.The International DETT Alliance signed up this consensus to standardize the procedures of DETT. In this consensus, we describe the definition, mechanism,and significance of DETT, prevention of infection and concepts of DETTassociated complications, methods to establish a submucosal tunnel, and application of DETT for lesions in the mucosa, in the MP and outside the GI tract(indications and contraindications, procedures, pre-and postoperative treatments, effectiveness, complications and treatments, and a comparison between DETT and other operations). | Ning-Li Chai Hui-Kai Li En-Qiang Linghu Zhao-Shen Li Shu-Tian Zhang Yu Bao Wei-Gang Chen Philip WY Chiu Tong Dang Wei Gong Shu-Tang Han Jian-Yu Hao Shui-Xiang He Bing Hu1 Bing Hu2 Xiao-Jun Huang Yong-Hui Huang Zhen-Dong Jin Mouen A Khashab James Lau Peng Li Rui Li De-Liang Liu Hai-Feng Liu Jun Liu Xiao-Gang Liu Zhi-Guo Liu Ying-Cai Ma Gui-Yong Peng Long Rong Wei-Hong Sha Pateek Sharma Jian-Qiu Sheng Shui-Sheng Shi Dong Wan Seo Si-Yu Sun Gui-Qi Wang Wen Wang Qi Wu Hong Xu Mei-Dong Xu Ai-Ming Yang Fang Yao Hong-Gang Yu Ping-Hong Zhou Bin Zhang Xiao-Feng Zhang Ya-Qi Zhai | 2019 | World Journal of Gastroenterology2019,25,7: | 5 |
| 11 | Analysis of Gene Expression Pattern of Lumbar Intervertebral Disc Degeneration in Human显示文摘ObjectiveTo investigate the gene expression changes in normal and degeneration lumbar intervertebral disc in humans, providing information for clinical. MethodsThe PCR products of 4096 human genes were spotted onto a kind of chemical-material-coated-glass slides. The total RNAs were isolated from the tissues. Both the mRNAs from the degeneration and normal lumbar intervertebral disc in humans were reversely transcribed to the cDNAs, which used as the hybridization probes with the incorporations of fluorescent dUTP. The mixed probes were then hybridized to the cDNA microarray. After high-stringent washing, the cDNA microarray was scanned for the fluorescent signals and analyzed with computer image analysis. ResultsAmong the 4096 targets, there were 706 genes whose expression levels differed between the degeneration and normal lumbar intervertebral disc in all cases, comprising 298 up-regulated and 358 down-regulated ones. ConclusionDNA microarray technology is an effective technique in screening for differently expressed genes between the degeneration and normal lumbar intervertebral disc. Cell apoptosis plays an important role in the process of lumbar intervertebral disc degeneration. | HU Ming MA Yuan-zheng FENG Hui-cheng CHEN Xing CHAI Xiao-jun PENG Wei LI Hong-wei | 2006 | 中国康复理论与实践2006,12,5: | 4 |
| 12 | Ectopic expression of VRT-A2 underlies the origin of Triticum polonicum and Triticum petropavlovskyi with long outer glumes and grains显示文摘Polish wheat (Triticum polonicum) is a unique tetraploid wheat species characterized by an elongated outer glume. The genetic control of the long-glume trait by a single semi-dominant locus, P1 (from Polish wheat), was established more than 100 years ago, but the underlying causal gene and molecular nature remain elusive. Here, we report the isolation of VRT-A2, encoding an SVP-clade MADS-box transcription factor, as the P1 candidate gene. Genetic evidence suggests that in T. polonicum, a naturally occurring sequence rearrangement in the intron-1 region of VRT-A2 leads to ectopic expression of VRT-A2 in floral organs where the long-glume phenotype appears. Interestingly, we found that the intron-1 region is a key ON/OFF molecular switch for VRT-A2 expression, not only because it recruits transcriptional repressors, but also because it confers intron-mediated transcriptional enhancement. Genotypic analyses using wheat accessions indicated that the P1 locus is likely derived from a single natural mutation in tetraploid wheat, which was subsequently inherited by hexaploid T. petropavlovskyi. Taken together, our findings highlight the promoter-proximal intron variation as a molecular basis for phenotypic differentiation, and thus species formation in Triticum plants. | Jing Liu Zhaoyan Chen Zhihui Wang Zhaoheng Zhang Xiaoming Xie Zihao Wang Lingling Chai Long Song Xuejiao Cheng Man Feng Xiaobo Wang Yanhong Liu Zhaorong Hu Jiewen Xing Zhenqi Su Huiru Peng Mingming Xin Yingyin Yao Weilong Guo Qixin Sun Jie Liu Zhongfu Ni | 2021 | Molecular Plant2021,14,9: | 4 |

| 14 | A new method of measuring optical turbulence of atmospheric surface layer at Antarctic Taishan Station with ultrasonic anemometer显示文摘To find the optimal location for large-aperture telescopes is a goal of astronomy. Chinese Antarctic astronomy has begun to flourish in recent years, and it is an urgent need in basic astronomical work to measure and analyze the optical turbulence spatiotemporal distribution in the Antarctic region. We analyzed turbulence data measured by a mobile atmospheric parameter measurement system from 30 December 2013 to 10 February 2014 at Antarctic Taishan Station. Because there is a discrepancy between the refractive index structure constant C_n^2 measured by an ultrasonic anemometer with a single-point temperature structure function method and by micro-thermometer, a new method to measure C_n^2 with a temperature spectrum method is proposed herein. Through comparing long-term continuous C_n^2 data derived from ultrasonic anemometer with those via the new method and micro-thermometer, trend, magnitude and measured weak turbulence of ~2×10^(-16)m^(-2/3) are generally satisfactory. The reason for the discrepancy in C_n^2 measurement between the ultrasonic anemometer with the old method and micro-thermometer is investigated. | WU Xiaoqing TIAN Qiguo JIANG Peng CHAI Bo QING Chun CAI Jun JIN Xinmiao ZHOU Hongyan | 2015 | Advances in Polar Science2015,26,4: | 3 |
| 15 | Processing Environmental Stimuli in Paranoid Schizophrenia:Recognizing Facial Emotions and Performing Executive Functions显示文摘Objective To study the contribution of executive function to abnormal recognition of facial expressions of emotion in schizophrenia patients. Methods Abnormal recognition of facial expressions of emotion was assayed according to Japanese and Caucasian facial expressions of emotion (JACFEE), Wisconsin card sorting test (WCST), positive and negative symptom scale, and Hamilton anxiety and depression scale, respectively, in 88 paranoid schizophrenia patients and 75 healthy volunteers. Results Patients scored higher on the Positive and Negative Symptom Scale and the Hamilton Anxiety and Depression Scales, displayed lower JACFEE recognition accuracies and poorer WCST performances. The JACFEE recognition accuracy of contempt and disgust was negatively correlated with the negative symptom scale score while the recognition accuracy of fear was positively with the positive symptom scale score and the recognition accuracy of surprise was negatively with the general psychopathology score in patients. Moreover, the WCST could predict the JACFEE recognition accuracy of contempt, disgust, and sadness in patients, and the perseverative errors negatively predicted the recognition accuracy of sadness in healthy volunteers. The JACFEE recognition accuracy of sadness could predict the WCST categories in paranoid schizophrenia patients. Conclusion Recognition accuracy of social-/moral emotions, such as contempt, disgust and sadness is related to the executive function in paranoid schizophrenia patients, especially when regarding sadness. | YU Shao Hua ZHU Jun Peng XU You ZHENG Lei Lei CHAI Hao HE Wei LIU Wei Bo LI Hui Chun WANG Wei | 2012 | Biomedical and Environmental Sciences2012,25,6: | 3 |
| 16 | Preparation of P(St-NMA)microsphere inks and their application in photonic crystal patterns with brilliant structural colors显示文摘Patterned photonic crystals with structural colors on textile substrates have attracted a special attention due to the great advantages in application,which currently become a research hot-spot.This study utilized an ink-jet printing technology to prepare high-quality photonic crystal patterns with structural colors on polyester substrates.The self-assembly temperature of poly(styrene-N-methylol acrylamide)(P(St-NMA))microspheres set to construct photonic crystals were deeply optimized.Moreover,the structural colors of prepared photonic crystal patterns were characterized and evaluated.When the mass fraction of P(St-NMA)microspheres was 1.0 wt.%,the pH value ranged from 5 to 7,and the surface tension was in the range of 63.79 to 71.20 mN/m,inks could present the best print performance.At 60°C,prepared P(St-NMA)microsphere inks were good for printing to obtain patterned photonic crystals with regular arrangement and beautiful structural colors.Specifically,photonic crystals with different colors could be constructed by regulating the diameter of microspheres in inks,and prepared structural colors exhibited distinct iridescent phenomenon.The present results could provide a theoretical basis for the industrial realization of patterned photonic crystals by ink-jet printing technology. | Guojin Liu Pengshuai Han Liqin Chai Peng Lu Yuping He Lan Zhou | 2020 | Frontiers of Materials Science2020,14,1: | 3 |

| 18 | SO_2 emission cap planning for Chengdu-Chongqing economic zone显示文摘The SO 2 emission sources of the Chengdu-Chongqing economic zone were divided into 556 emissions units according to four different categories,which are city,industry,point sources,and area sources.The CALPUFF model was used to calculate the contribution of each unit,and consequently obtain an influence-transferring matrix.To ensure that the SO 2 concentrations of 46 cities and counties in the Chengdu-Chongqing economic zone meet air quality standards,an emission optimization model was developed to calculate optimal emissions of each emission unit under different development scenarios.The result showed the optimal emissions of SO 2 by different provinces and industries.To achieve the target of restricting and optimizing development,corresponding planning programs were developed for every district. | Peng Yi Ning Duan Fahe Chai Yaxuan Xu Youjiang He | 2012 | Journal of Environmental Sciences2012,24,1: | 3 |
| 19 | Two-plane painting injection scheme for BRing of HIAF显示文摘The high-intensity heavy-ion accelerator facility(HIAF)is under design at the Institute of Modern Physics(IMP)and will provide an intense ion beam for nuclear physics,atomic mass measurement research,and other applications.As the main ring of HIAF,the BRing accumulates beams to high intensity and accelerates them to high energy.To achieve high intensities up to 1×10^(11)(^(238)U^(34+)),the injection gain of the BRing must be as high as 88.However,multiple multiturn injection supported by the electron cooling system takes a long time,causing substantial beam loss under a strong space charge effect.Hence,a two-plane painting injection scheme is proposed for beam accumulation in the BRing.This scheme uses a tilted injection septum and horizontal and vertical bump magnets to paint the beam into horizontal and vertical phase space simultaneously.In this paper,the two-plane painting injection parameters are optimized,and the resulting injection process is simulated using the Objective Ring Beam Injection and Tracking(ORBIT)code.An injection gain of up to 110.3 with a loss rate of 2:3%is achieved,meeting the requirements of BRing. | Guo-Feng Qu Wei-Ping Chai Jia-Wen Xia Jian-Cheng Yang Heng Du Zhong-Shan Li Wen-Wen Ge Wen-Heng Zheng Peng Shang | 2017 | Nuclear Science and Techniques2017,28,8: | 3 |
