1Progresses 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 2012Science China Earth Sciences2012,55,7:24
2Comparative effect of electroacupuncture and moxibustion on the expression of substance P and vasoactive intestinal peptide in patients with irritable bowel syndrome显示文摘OBJECTIVE: To compare the impacts of electroacupuncture(EA) and moxibustion(Mox) on the primary gastrointestinal symptoms and the expressions of colonic mucosa-associated neuropeptide substance P(SP) and vasoactive intestinal peptide(VIP)in patients with either diarrhea-predominant or constipation-predominant irritable bowel syndrome(IBS-D and IBS-C,respectively).METHODS: Eighty-five IBS patients were randomly allocated to the EA and Mox groups. Zusanli(ST 36)and Shangjuxu(ST 37) were selected as acupoints for electroacupuncture or warm moxibustion treatment once a day for 14 consecutive days. Before and after the treatment sessions,a Visual Analog Pain Scale and the Bristol Stool Form Scale were used to evaluate gastrointestinal symptoms. There were four dropout cases,leaving 81 participants(41 with IBS-D and 40 with IBS-C) who volunteered to undergo colonoscopy before and after the treatment sessions. During colonoscopy,sigmoid mucosa were collected to detect SP and VIP expression using immunohistochemistry assay.RESULTS: Both EA and Mox treatments were effective at relieving abdominal pain in IBS-D and IBS-C patients. However,Mox was more effective at reducing diarrhea in IBS-D patients,whereas EA was more effective at improving constipation in IBS-C patients. EA and Mox treatments both down-regulated the abnormally increased SP and VIP expression in the colonic mucosa,with no significant difference shown between the two treatments.CONCLUSION: Both EA and Mox treatments are effective at ameliorating gastrointestinal symptoms by reducing SP and VIP expression in the colonic mucosa of IBS patients.Lu Zhenzhong Yin Xiaojun Teng Weijun Chen Yuehua Sun Jie Zhao Jimeng Wang Anqi Bao Chunhui Shi Yin 2015Journal of Traditional Chinese Medicine2015,35,4:24
3Motion trajectory prediction based on a CNN-LSTM sequential model显示文摘Accurate monitoring the surrounding environment is an important research direction in the field of unmanned systems such as bio-robotics,and has attracted much research attention in recent years.The trajectories of surrounding vehicles should be predicted accurately in space and time to realize active defense and running safety of an unmanned system.However,there is uncertainty and uncontrollability in the process of trajectory prediction of surrounding obstacles.In this study,we propose a trajectory prediction method based on a sequential model,that fuses two neural networks of a convolutional neural network(CNN)and a long short-term memory network(LSTM).First,a box plot is used to detect and eliminate abnormal values of vehicle trajectories,and valid trajectory data are obtained.Second,the trajectories of surrounding vehicles are predicted by merging the characteristics of CNN space expansion and LSTM time expansion;the hyper-parameters of the model are optimized according to a grid search algorithm,which satisfies the double-precision prediction requirement in space and time.Finally,data from next generation simulation(NGSIM)and Creteil roundabout in France are taken as test cases;the correctness and rationality of the method are verified by prediction error indicators.Experimental results demonstrate that the proposed CNNLSTM method is more accurate and features a shorter time cost,which meets the prediction requirements and provides an effective method for the safe operation of unmanned systems.Guo XIE Anqi SHANGGUAN Rong FEI Wenjiang JI Weigang MA Xinhong HEI 2020Science China(Information Sciences)2020,63,11:24
4Elimination of senescent cells byβ-galactosidase-targeted prodrug attenuates inflammation and restores physical function in aged mice显示文摘Cellular senescence,a persistent state of cell cycle arrest,accumulates in aged organisms,contributes to tissue dysfunction,and drives age-related phenotypes.The clearance of senescent cells is expected to decrease chronic,low-grade inflammation and improve tissue repair capacity,thus attenuating the decline of physical function in aged organisms.However,selective and effective clearance of senescent cells of different cell types has proven challenging.Herein,we developed a prodrug strategy to design a new compound based on the increased activity of lysosomalβ-galactosidase(β-gal),a primary characteristic of senescent cells.Our prodrug SSK1 is specifically activated byβ-gal and eliminates mouse and human senescent cells independently of senescence inducers and cell types.In aged mice,our compound effectively cleared senescent cells in different tissues,decreased the senescence-and age-associated gene signatures,attenuated low-grade local and systemic inflammation,and restored physical function.Our results demonstrate that lysosomalβ-gal can be effectively leveraged to selectively eliminate senescent cells,providing a novel strategy to develop anti-aging interventions.Yusheng Cai Huanhuan Zhou Yinhua Zhu Qi Sun Yin Ji Anqi Xue Yuting Wang Wenhan Chen Xiaojie Yu Longteng Wang Han Chen Cheng Li Tuoping Luo Hongkui Deng 2020Cell Research2020,30,7:12

6Biomass-derived porous carbon highly efficient for removal of Pb(Ⅱ) and Cd(Ⅱ)显示文摘The utilization of abundant and renewable biomass to fabricate advanced functional materials is considered a promising route for environmental applications.Herein,Lignin-based porous carbon with layered graphene-like structure(LPC)is successfully synthesized and applied to efficiently remove Pb(Ⅱ)and Cd(Ⅱ).The as-synthesized LPC materials are systematically characterized and these results show that LPC has a porous graphene-like structure,facilitating the diffusion and immobilization of heavy metal ions.The influence of different reaction parameters(solution pH,initial concentration of metal ions,contact time and adsorbent amount)on the adsorption performance is investigated in details.The results demonstrate that LPC can achieve superior adsorption capacities of 250.5 mg·g^-1 for Pb(Ⅱ)and 126.4 mg·g^-1 for Cd(Ⅱ),which are far superior to the previously reported adsorbents.Pseudo-second order kinetics model and Freundlich isotherm model describe the adsorption process well.Furthermore,the exhausted LPC can be regenerated easily and exhibits the removal efficiency of 96%and 92%for Pb(Ⅱ)and Cd(Ⅱ)after five continuous runs,respectively.This study shows a sustainable strategy for the design of porous carbon material from na?ve biomass and highlights the great potential in wastewater treatment.Anqi Wang Zhikeng Zheng Ruiqi Li Di Hu Yiran Lu Huixia Luo Kai Yan 2019Green Energy & Environment2019,4,4:10
7Primarily screening and analyzing ESTs differentially expressed in rats' primary liver cancer显示文摘Objective: To screen and analyze key express sequence tags (ESTs) which were differentially displayed in every period of SD rats' primary hepatic carcinoma and reveal the molecular mechanism of carcinogenesis. Methods: Using diethylnitrosamine (DENA) as a cancerigenic agent, animal models with different phases of primary hepatic cancer were constructed in SD rats. Rats were respectively sacrificed at d 14, d 28, d 56, d 77, d 105 and d 112 after the rats received DENA by gavage, then the livers were harvested. One part of the livers was classified according to their pathological changes, while the other was reserved for molecular mechanism studies on hepatocarcinogenesis. The differentially expressed genes were isolated from both normal and morbid tissues by mRNA differential display technique (DDRT-PCR). After the fragments were sequenced, bioinformatics were used to analyze the results. Results: Twelve differentially expressed cDNA fragments were obtained. Nine fragments had the homology with known cDNA clones, especially EST-7 was similar to BN/SsNHsdMCW mitochondrion gene and the identity was 100% which suggested EST-7 may be the part of BN/SsNHsdMCW mitochondrion gene. In contrast, other three fragments (EST-1, EST-3 and EST-5) had extremely low identity to any genes registered in GENBANK databases. Conclusions: BN/SsNHsdMCW mitochondrion gene was expressed in different periods of hepatocarcinogenesis. Moreover, EST-1, EST-3 and EST-5 were suggested to contribute to the development of rat hepatocarcinogenesis, and thus may be candidates of new targets of oncogenes or cancer suppressor genes.Dandan Liu Lijuan Zhi Mingxia Ma Dan Qiao Meijuan Wang Yawei Wang Baijie Jin Anqi Li Guting Liu Yiqing Zhang Yanyan Song Hongxu Zhang 2013Chinese Journal of Cancer Research2013,25,1:9
8Osteoblast/fibroblast coculture derived bioactive ECM with unique matrisome profile facilitates bone regeneration显示文摘Extracellular matrix(ECM)with mimetic tissue niches was attractive to facilitate tissue regeneration in situ via recruitment of endogenous cells and stimulation of self-healing process.However,how to engineer the complicate tissue specific ECM with unique matrisome in vitro was a challenge of ECM-based biomaterials in tissue engineering and regenerative medicine.Here,we introduced coculture system to engineer bone mimetic ECM niche guided by cell-cell communication.In the cocultures,fibroblasts promoted osteogenic differentiation of osteoblasts via extracellular vesicles.The generated ECM(MN-ECM)displayed a unique appearance of morphology and biological components.The advantages of MN-ECM were demonstrated with promotion of multiple cellular behaviors(proliferation,adhesion and osteogenic mineralization)in vitro and bone regeneration in vivo.Moreover,proteomic analysis was used to clarify the molecular mechanism of MN-ECM,which revealed a specific matrisome signature.The present study provides a novel strategy to generate ECM with tissue mimetic niches via cell-cell communication in a coculture system,which forwards the development of tissue-bioactive ECM engineering along with deepening the understanding of ECM niches regulated by cells for bone tissue engineering.Mei Li Anqi Zhang Jiajing Li Jing Zhou Yanan Zheng Chi Zhang Dongdong Xia Haijiao Mao Jiyuan Zhao 2020Bioactive Materials2020,5,4:7

11Chinese multidisciplinary guideline for management of hypertensiveintracerebral hemorrhage显示文摘ypertensive intracerebral hemorrhage(HICH)refers tothe sudden onset of hemorrhage within cerebral paren-chyma or ventricles of patients with a history ofhypertension.Secondary intracerebral hemorrhage(ICH)with an underlying causative pathology,such astrauma,structural blood vessel abnormalities,coagulationor hematological disorder(s),systemic diseases,or neo-plasms,should be excluded to make the diagnosis ofHICH.HICH is characterized by high incidence,disabili-ty,mortality,and recurrence rates.In 2015,experts fromthe Chinese Medical Association branch of Neurosurgery,Chinese Medical Doctor Association branch of theEmergency Physician and Stroke Screening,and Preven-tion and Treatment Committee of the National HealthCommission of the People’s Republic of China gathered toformulate and draft the Chinese Multidisciplinary ExpertsConsensus on the Management of Spontaneous Intrace-rebral Hemorrhage.[1]This consensus has played animportant role in guiding and standardizing the manage-ment of spontaneous ICH in China.Zhiyuan Yu Chuanyuan Tao Anqi Xiao Cong Wu Min Fu Wei Dong Ming Liu Xuezhong Yu Chao You 2022Chinese Medical Journal2022,135,19:6
12A New Method of Wind Turbine Bearing Fault Diagnosis Based on Multi-Masking Empirical Mode Decomposition and Fuzzy C-Means Clustering显示文摘Based on Multi-Masking Empirical Mode Decomposition (MMEMD) and fuzzy c-means (FCM) clustering, a new method of wind turbine bearing fault diagnosis FCM-MMEMD is proposed, which can determine the fault accurately and timely. First, FCM clustering is employed to classify the data into different clusters, which helps to estimate whether there is a fault and how many fault types there are. If fault signals exist, the fault vibration signals are then demodulated and decomposed into different frequency bands by MMEMD in order to be analyzed further. In order to overcome the mode mixing defect of empirical mode decomposition (EMD), a novel method called MMEMD is proposed. It is an improvement to masking empirical mode decomposition (MEMD). By adding multi-masking signals to the signals to be decomposed in different levels, it can restrain low-frequency components from mixing in highfrequency components effectively in the sifting process and then suppress the mode mixing. It has the advantages of easy implementation and strong ability of suppressing modal mixing. The fault type is determined by Hilbert envelope finally. The results of simulation signal decomposition showed the high performance of MMEMD. Experiments of bearing fault diagnosis in wind turbine bearing fault diagnosis proved the validity and high accuracy of the new method.Yongtao Hu Shuqing Zhang Anqi Jiang Liguo Zhang Wanlu Jiang Junfeng Li 2019Chinese Journal of Mechanical Engineering2019,32,3:6
13Polymorphism-Dependent Dynamic Ultralong Organic Phosphorescence显示文摘Developing ultralong organic phosphorescence(UOP)materials with smart response to external stimuli is of great interest in photonics applications,whereas the manipulation of molecular stacking on tuning such dynamic UOP is still a formidable challenge.Herein,we have reported two polymorphs with distinct photoactivated dynamic UOP behavior based on a pyridine derivative for the first time.Our experiment revealed that the dynamic UOP behavior including photoactivation and deactivation feature is highly dependent on irradiation intensity and environmental atmosphere.Additionally,given the unique dynamic UOP feature,these phosphors have been successfully applied to phosphorescence-dependent molecular logic gate and timing data storage.This result not only paves a way to design smart functional materials but also expands the scope of the applications on organic phosphorescence materials.Mingxing Gu Huifang Shi Kun Ling Anqi Lv Kaiwei Huang Manjeet Singh He Wang Long Gu Wei Yao Zhongfu An Huili Ma Wei Huang 2020Research2020,,1:5
14Macrophage-derived small extracellular vesicles promote biomimetic mineralized collagen-mediated endogenous bone regeneration显示文摘Macrophages play an important role in material-related immune responses and bone formation,but the functionality of macrophage-derived extracellular vesicles(EVs)in material-mediated bone regeneration is still unclear.Here,we evaluated intracellular communication through small extracellular vesicles(sEVs)and its effects on endogenous bone regeneration mediated by biomimetic intrafibrillarly mineralized collagen(IMC).After implantation in the bone defect area,IMC generated more neobone and recruited more mesenchymal stem cells(MSCs)than did extrafibrillarly mineralized collagen(EMC).More CD63+CD90+and CD63+CD163+cells were detected in the defect area in the IMC group than in the EMC group.To determine the functional roles of sEVs,extracellular vesicles from macrophages cultured on different mineralized collagen were isolated,and they showed no morphological differences.However,macrophage-derived sEVs in the IMC group showed an enhanced Young’s modulus and exerted beneficial effects on the osteogenic differentiation of bone marrow MSCs by increasing the expression of the osteoblastic differentiation markers BMP2,BGLAP,COL1,and OSX and calcium nodule formation.Mechanistically,sEVs from IMC-treated macrophages facilitated MSC osteogenesis through the BMP2/Smad5 pathway,and blocking sEV secretion with GW4869 significantly impaired MSC proliferative,immunomodulative and osteogenic potential.Taken together,these findings show that macrophage-derived sEVs may serve as an emerging functional tool in biomaterial-mediated endogenous bone regeneration.Anqi Liu Shanshan Jin Cuicui Fu Shengji Cui Ting Zhang Lisha Zhu Yu Wang Steve G.F.Shen Nan Jiang Yan Liu 2020International Journal of Oral Science2020,12,4:5
15Urbanization reduces resource use efficiency of phytoplankton community by altering the environment and decreasing biodiversity显示文摘Urbanization often exerts multiple effects on aquatic and terrestrial organisms,including changes in biodiversity,species composition and ecosystem functions.However,the impacts of urbanization on river phytoplankton in subtropical urbanizing watersheds remain largely unknown.Here,we explored the effects of urbanization on phytoplankton community structure(i.e.,biomass,community composition and diversity)and function(i.e.,resource use efficiency)in a subtropical river at watershed scale in southeast China over 6 years.A total of 318 phytoplankton species belonging into 120 genera and 7 phyla were identified from 108 samples.Bacillariophyta biomass showed an increasing trend with increasing urbanization level.The phytoplankton community shifted from Chlorophyta dominance in rural upstream waters to Bacillariophyta dominance in urbanized downstream waters.Furthermore,phytoplankton diversity and resource use efficiency(RUE=phytoplankton biomass/total phosphorus)were significantly decreased with increasing urbanization level from upstream to downstream.Phytoplankton RUE exhibited a significant positive correlation with species richness,but a negative correlation with phytoplankton evenness.The variation in environmental factors(turbidity,total nitrogen,NH_(4)^(+)-N,total phosphorus,PO_(4)^(3-)-P and percentage urbanized area)was significantly correlated with phytoplankton diversity and RUE.Overall,our results revealed the influence of urbanization on phytoplankton community structure and ecosystem function was due to its altering the environmental conditions.Therefore,human-driven urbanization may play crucial roles in shaping the structure and function of phytoplankton communities in subtropical rivers,and the mechanism of this process can provide important information for freshwater sustainable uses,watershed management and conservation.Yigang Yang Huihuang Chen Mamun Abdullah Al Jean Claude Ndayishimiye Jun R Yang Alain Isabwe Anqi Luo Jun Yang 2022Journal of Environmental Sciences2022,34,2:4
16A Multiresponsive Hydrophobic Associating Hydrogel Based on Azobenzene and Spiropyran显示文摘Summary of main observation and conclusion Stimuli-responsive hydrogels crosslinked by weak noncovalent bonds such as hydrogen bonds,ionic interactions,host-guest interactions and hydrophobic interactions have been extensively investigated.Herein,azobenzene and spiropyran acting as two hydrophobic pendant groups were introduced into a hydrophilic polyacrylamide (PAM) via free radical copolymerization to construct a hydrophobic interaction based thermo-,light-responsive polymer hydrogel.Its viscosity and color could be reversibly regulated by heating and cooling.Meanwhile,its color could be specifically switched by light without obvious viscosity change.The gel was also capable of being transited to sol by addition of β-cyclodextrin (β-CD),which encaged the hydrophobic groups and then increased the solubility of polymer in water.The hydrogel could be regained after UV irradiation at λ=365 nm,and after irradiation at λ=440 nm,the hydrogel changed into a clear sol again.Anqi Liu Chenxiao Xiong Xiaoying Ma Wenjing Ma Ruyi Sun 2019Chinese Journal of Chemistry2019,37,8:4

18Immunization effect of purified bivalent vaccine to haemorrhagic fever with renal syndrome manufactured from primary cultured hamster kidney cells显示文摘Haemorrhagic fever with renal syndrome (HFRS) is a worldwide epidemic plaguing over thirty nations. This disease has spread across 26 provinces, cities and autonomous regions of China with an annual onsets number of more than a hundred thousand and a mortality rate of 5% to 15%, accounting for over 80% of cases in the world, and threatening the safety and health of Chinese people. 1 Analysis of serum samples over recent years indicates that the plagued areas are expanding. Instead of a single type Ⅰ or Ⅱ strain, each area now has a combination with one type predominant. 2 These demographic changes revealed a shortcoming of the monovalent vaccine in use, urging China to develop a purified bivalent vaccine based on monovalent one. This research on clinical observation and immunization effects led to a purified bivalent vaccine manufactured by Changchun Institute of Biological Products, China from primary cultured hamster kidney cells.DONGGuan-mu HANLiang ANQi LIUWen-xue KONGYan YANGLi-hong 2005Chinese Medical Journal2005,,9:4
19SOX4 contributes to TGF-β-induced epithelialemesenchymal transition and stem cell characteristics of gastric cancer cells显示文摘SOX4 is highly expressed in gastric cancer(GC)and is associated with tumor grade,metastasis and prognosis,however the mechanism is not clear.We report herein that SOX4 was upregulated and overexpression of SOX4 was associated with increased expression of the markers of Epithelialemesenchymal transition(EMT)and stemness in clinic patient samples.In vitro,overexpression of SOX4 promoted the invasion as showed by Transwell assay and stemness of GC cells as assessed by sphere formation assay,which was suppressed by silencing SOX4 with shRNA.Further studies showed that SOX4 up-regulated the expression of EMT transcription factors Twist1,snail1 and zeb1 and stemness transcription factors SOX2 and OCT4,and promoted the nuclear translocation of β-catenin.Moreover,we revealed that TGF-β treatment significantly up-regulated the expression of SOX4 and silencing SOX4 reversed TGF-β induced invasion and sphere formation ability of GC cells.Finally,we showed that SOX4 promoted the lung metastasis and tumor formation ability of gastric cancer cells in nude mice.Our results suggest that SOX4 is a target TGF-β signaling and mediates TGF-β-induced EMT and stem cell characteristics of GC cells,revealing a novel role of TGF-β/SOX4 axis in the regulation of malignant behavior of GC.Xudong Peng Guangyi Liu Hongxia Peng Anqi Chen Lang Zha Ziwei Wang 2018Genes & Diseases2018,5,1:4
