1Antioxidative mechanism of Lycium barbarum polysaccharides promotes repair and regeneration following cavernous nerve injury显示文摘Polysaccharides extracted from Lycium barbarum exhibit antioxidant properties.We hypothesized that these polysaccharides resist oxidative stress-induced neuronal damage following cavernous nerve injury.In this study,rat models were intragastrically administered Lycium barbarum polysaccharides for 2 weeks at 1,7,and 14 days after cavernous nerve injury.Serum superoxide dismutase and glutathione peroxidase activities significantly increased at 1 and 2 weeks post-injury.Serum malondialdehyde levels decreased at 2 and 4 weeks.At 12 weeks,peak intracavernous pressure,the number of myelinated axons and nicotinamide adenine dinucleotide phosphate-diaphorase-positive nerve fibers,levels of phospho-endothelial nitric oxide synthase protein and 3-nitrotyrosine were higher in rats administered at 1 day post-injury compared with rats administered at 7 and 14 days post-injury.These findings suggest that application of Lycium barbarum polysaccharides following cavernous nerve crush injury effectively promotes nerve regeneration and erectile functional recovery.This neuroregenerative effect was most effective in rats orally administered Lycium barbarum polysaccharides at 1 day after cavernous nerve crush injury.Zhan-kui Zhao Hong-lian Yu Bo Liu Hui Wang Qiong Luo Xie-gang Ding 2016Neural Regeneration Research2016,11,8:25
2Trend of mass change in the Antarctic ice sheet recovered from the GRACE temporal gravity field显示文摘It is important to quantify mass variations in the Antarctic ice sheet to study the global sea-level rise and climate change. A hybrid filtering scheme employing a combination of the decorrelated filter P3M6 and 300 km Fan filter was used, and the sur- face mass variations over the Antarctic are recovered from GRACE CSR RL04 monthly gravity field models from August 2002 to June 2010. After deduction of leakage errors using the GLDAS hydrological model and postglacial rebound effects using the glacial isostatic adjustment model IJ05, the variations in the ice sheet mass are obtained. The results reveal that the rate of melting of the Antarctic ice sheet is 80.0 Gt/a and increasing and contributes 0.22 mm/a to the global sea-level rise; the mass loss rate is 78.3 Gt/a in the West Antarctic and 1.6 Gt/a in the East Antarctic. The average mass loss rate increases from 39.3 Gt/a for the period 2002-2005 to 104.2 Gt/a for the period 2006-2010, and its corresponding contribution to the global sea-level rise increases from 0.11 to 0.29 mm/a, which indicates accelerated ice mass loss over the Antarctic since 2006. Moreover, the mass accumulation rates for Enderby Land and Wilkes Land along the coast of East Antarctica decrease for the period 2006-2008 but increase evidently after 2009.LUO ZhiCai LI Qiong ZHANG Kun WANG HaiHong 2012Science China Earth Sciences2012,55,1:21
3Simvastatin inhibits apoptosis of endothelial cells induced by sepsis through upregulating the expression of Bcl-2 and downregulating Bax显示文摘BACKGROUND: Many studies have showed that apoptosis of endothelial cells plays a curial role in the progress of sepsis. But the role of simvastatin in apoptosis of endothelial cells induced by sepsis is not clear. The present study aimed to investigate the role of simvastatin in apoptosis of endothelial cells induced by sepsis and its mechanism.METHODS: Human umbilical vein endothelial cells(HUVECs) were randomly divided into three groups: control group, sepsis serum intervention group(sepsis group) and simvastatin+sepsis serum intervention group(simvastatin group). After 24-hour incubation with corresponding culture medium, the relative growth rate of HUVECS in different groups was detected by MTT assay; the apoptosis of HUVECs was detected by Hoechst33258 assay and fl ow cytometry; and the expression of the Bcl-2 and Bax genes of HUVECs was detected by PCR.RESULTS: Compared with the sepsis group, HUVECs in the simvastatin group had a higher relative growth rate. Apoptotic HUVECs decreased significantly in the simvastatin group in comparison with the sepsis group. Expression of the Bcl-2 gene in HUVECs decreased obviously, but the expression of the Bax gene increased obviously after 24-hour incubation with sepsis serum; however, the expression of the Bcl-2 and Bax genes was just the opposite in the simvastatin group.CONCLUSIONS: Our study suggests that simvastatin can inhibit apoptosis of endothelial cells induced by sepsis through upregulating the expression of Bcl-2 and downregulating Bax. It may be one of the mechanisms for simvastatin to treat sepsis.Hui Fu Qiao-sheng Wang Qiong Luo Si Tan Hua Su Shi-lin Tang Zheng-liang Zhao Li-ping Huang 2014World Journal of Emergency Medicine2014,5,4:18

5Diversity and Genetic Differentiation of the Whitefly Bemisia tabaci Species Complex in China Based on mtCOI and cDNA-AFLP Analysis显示文摘The whitefly Bemisia tabaci are considered as a taxonomically complex that contained some destructive pests.Two of the most prevalent cryptic species are B.tabaci Middle East-Asia Minor 1(MEAM1)and Mediterranean(MED).In an extensive field survey of the B.tabaci complex present throughout part of China from 2004 to 2007,we obtained 93 samples of B.tabaci from 22 provinces.We determined that these Chinese haplotypes included 2 invasive species(MEAM1 and MED),and 4 indigenous cryptic species(Asia II 1,Asia II 3,China 3 and Asia II 7)by sequencing mitochondrial cytochrome oxidose one gene(mtCOI).The diversity and genetic differentiation of a subset of 19 populations of B.tabaci were studied using cDNA amplified fragment length polymorphism(AFLP).Prior to 2007,MEAM1 was a dominant species in many provinces in China.By 2007,MED was dominant in 11 provinces.Both invasive and indigenous species were simultaneously found in some regions.Indigenous species of B.tabaci were found in six provinces in southern China.MED and MEAM1 have broad ranges of host plants,and indigenous species appeared to have much narrower host ranges.All Asia II 3 samples were found on cotton except one on aubergine.China 3 has more host plants than Asia II 3.Twelve samples of China 3 were collected from sweet potato,Japanese hop,squash and cotton.A total of 677 reproducible bands amplified with 5 AFLP primer combinations were obtained.The highest proportion of polymorphic bands was 98.7% and the lowest was 91.9%.Unweighted pair-group method analysis indicated that the clustering was independent of the different species.MED showed the lowest degree of similarity than the other species.The data indicate that both MEAM1and MED were rapidly established in China.GUO Xiao-jun RAO Qiong ZHANG Fan LUO Chen ZHANG Hong-yu GAO Xi-wu 2012Journal of Integrative Agriculture2012,11,2:14
6Spin-decoupled metasurface for simultaneous detection of spin and orbital angular momenta via momentum transformation显示文摘With inherent orthogonality,both the spin angular momentum(SAM)and orbital angular momentum(OAM)of photons have been utilized to expand the dimensions of quantum information,optical communications,and information processing,wherein simultaneous detection of SAMs and OAMs with a single element and a single-shot measurement is highly anticipated.Here,a single azimuthal-quadratic phase metasurface-based photonic momentum transformation(PMT)is illustrated and utilized for vortex recognition.Since different vortices are converted into focusing patterns with distinct azimuthal coordinates on a transverse plane through PMT,OAMs within a large mode space can be determined through a single-shot measurement.Moreover,spin-controlled dual-functional PMTs are proposed for simultaneous SAM and OAM sorting,which is implemented by a single spin-decoupled metasurface that merges both the geometric phase and dynamic phase.Interestingly,our proposed method can detect vectorial vortices with both phase and polarization singularities,as well as superimposed vortices with a certain interval step.Experimental results obtained at several wavelengths in the visible band exhibit good agreement with the numerical modeling.With the merits of ultracompact device size,simple optical configuration,and prominent vortex recognition ability,our approach may underpin the development of integrated and high-dimensional optical and quantum systems.Yinghui Guo Shicong Zhang Mingbo Pu Qiong He Jinjin Jin Mingfeng Xu Yaxin Zhang Ping Gao Xiangang Luo 2021Light(Science & Applications)2021,10,4:14
7Enhanced absorption and inhibited metabolism of emodin by 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucopyranoside: Possible mechanisms for Polygoni Multiflori Radix-induced liver injury显示文摘Polygoni Multiflori Radix(PMR) has been commonly used as a tonic in China for centuries. However, PMR-associated hepatotoxicity is becoming a safety issue. In our previous in vivo study, an interaction between stilbenes and anthraquinones has been discovered and a hypothesis is proposed that the interaction between stilbene glucoside-enriching fraction and emodin may contribute to the side effects of PMR. To further support our previous in vivo results in rats, the present in vitro study was designed to evaluate the effects of 2, 3, 5, 4'-tetrahydroxystilbene-2-O-β-D-glucopyranoside(TSG) on the cellular absorption and human liver microsome metabolism of emodin. The obtained results indicated that the absorption of emodin in Caco-2 cells was enhanced and the metabolism of emodin in human liver microsomes was inhibited after TSG treatment. The effects of the transport inhibitors on the cellular emodin accumulation were also examined. Western blot assay suggested that the depressed metabolism of emodin could be attributed to the down-regulation of UDP-glucuronosyltransferases(UGTs) 1A8, 1A10, and 2B7. These findings definitively demonstrated the existence of interaction between TSG and emodin, which provide a basis for a better understanding of the underlying mechanism for PMR-induced liver injury.YU Qiong JIANG Li-Long LUO Na FAN Ya-Xi MA Jiang LI Ping LI Hui-Jun 2017Chinese Journal of Natural Medicines2017,15,6:12
8Nissen fundoplication vs proton pump inhibitors for laryngopharyngeal reflux based on p H-monitoring and symptom-scale显示文摘AIM To compare the outcomes between laparoscopic Nissen fundoplication(LNF)and proton pump inhibitors(PPIs)therapy in patients with laryngopharyngeal reflux(LPR)and typeⅠhiatal hernia diagnosed by oropharyngeal p H-monitoring and symptom-scale assessment.METHODS From February 2014 to January 2015,70 patients who were diagnosed with LPR and type I hiatal hernia and referred for symptomatic assessment,oropharyngeal p H-monitoring,manometry,and gastrointestinal endoscopy were enrolled in this study.All of the patients met the inclusion criteria.All of the patients underwent LNF or PPIs administration,and completed a2-year follow-up.Patients’baseline characteristics and primary outcome measures,including comprehensive and single symptoms of LPR,PPIs independence,and satisfaction,and postoperative complications were assessed.The outcomes of LNF and PPIs therapy were analyzed and compared. RESULTS There were 31 patients in the LNF group and 39patients in the PPI group.Fifty-three patients(25 in the LNF group and 28 in the PPI group)completed reviews and follow-up.Oropharyngeal p H-monitoring parameters were all abnormal with high acid exposure,a large amount of reflux,and a high Ryan score,associated reflux symptom index(RSI)score.There was a significant improvement in the RSI and LPR symptom scores after the 2-year follow-up in both groups(P<0.05),as well as typical symptoms of gastroesophageal reflux disease.Improvement in the RSI(P<0.005)and symptom scores of cough(P=0.032),mucus(P=0.011),and throat clearing(P=0.022)was significantly superior in the LNF group to that in the PPI group.After LNF and PPIs therapy,13 and 53 patients achieved independence from PPIs therapy(LNF:44.0%vs PPI:7.14%,P<0.001)during follow-up,respectively.Patients in the LNF group were more satisfied with their quality of life than those in the PPI group(LNF:62.49±28.68 vs PPI:44.36±32.77,P=0.004).Body mass index was significantly lower in the LNF group than in the PPI group(LNF:22.2±3.1kg/m^2 vs PPI:25.1±2.9 kg/m^2,P=0.001).CONCLUSION Diagnosis of LPR should be assessed with oropharyngeal p H-monitoring,manometry,and the symptom-scale.LNF achieves better improvement than PPIs for LPR with type I hiatal hernia.Chao Zhang Zhi-Wei Hu Chao Yan Qiong Wu Ji-Min Wu Xing Du Dian-Gang Liu Tao Luo Fei Li Zhong-Gao Wang 2017World Journal of Gastroenterology2017,23,19:12

10Generation of GGTA1 biallelic knockout pigs via zinc-finger nucleases and somatic cell nuclear transfer显示文摘Genetically modified pigs are valuable models of human disease and donors of xenotransplanted organs.Conventional gene targeting in pig somatic cells is extremely inefficient.Zinc-finger nuclease(ZFN)technology has been shown to be a powerful tool for efficiently inducing mutations in the genome.However,ZFN-mediated targeting in pigs has rarely been achieved.Here,we used ZFNs to knock out the porcineα-1,3-galactosyl-transferase(GGTA1)gene,which generates Gal epitopes that trigger hyperacute immune rejection in pig-to-human transplantation.Primary pig fibroblasts were transfected with ZFNs targeting the coding region of GGTA1.Eighteen mono-allelic and four biallelic knockout cell clones were obtained after drug selection with efficiencies of 23.4%and 5.2%,respectively.The biallelic cells were used to produce cloned pigs via somatic cell nuclear transfer(SCNT).Three GGTA1 null piglets were born,and one knockout primary fibroblast cell line was established from a cloned fetus.Gal epitopes on GGTA1 null pig cells were completely eliminated from the cell membrane.Functionally,GGTA1 knockout cells were protected from complement-mediated immune attacks when incubated with human serum.This study demonstrated that ZFN is an efficient tool in creating gene-modified pigs.GGTA1 null pigs and GGTA1 null fetal fibroblasts would benefit research and pig-to-human transplantation.BAO Lei CHEN HaiDe JONG UiMyong RIM CholHo LI WenLing LIN XiJuan ZHANG Dan LUO Qiong CUI Chun HUANG HeFeng ZHANG Yan XIAO Lei FU ZhiXin 2014Science China(Life Sciences)2014,57,2:9
11Terrestrial water storage changes over the Pearl River Basin from GRACE and connections with Pacific climate variability显示文摘Time-variable gravity data from the Gravity Recovery and Climate Experiment(GRACE)satellite mission are used to study terrestrial water storage(TWS) changes over the Pearl River Basin(PRB) for the period 2003 eN ov. 2014. TWS estimates from GRACE generally show good agreement with those from two hydrological models GLDAS and WGHM. But they show different capability of detecting significant TWS changes over the PRB. Among them,WGHM is likely to underestimate the seasonal variability of TWS, while GRACE detects longterm water depletions over the upper PRB as was done by hydrological models, and observes significant water increases around the Longtan Reservoir(LTR) due to water impoundment.The heavy drought in 2011 caused by the persistent precipitation deficit has resulted in extreme low surface runoff and water level of the LTR. Moreover, large variability of summer and autumn precipitation may easily trigger floods and droughts in the rainy season in the PRB, especially for summer, as a high correlation of 0.89 was found between precipitation and surface runoff. Generally, the PRB TWS was negatively correlated with El Nin^o-Southern Oscillation(ENSO) events. However, the modulation of the Pacific Decadal Oscillation(PDO)may impact this relationship, and the significant TWS anomaly was likely to occur in the peak of PDO phase as they agree well in both of the magnitude and timing of peaks. This indicates that GRACE-based TWS could be a valuable parameter for studying climatic influences in the PRB.Zhicai Luo Chaolong Yao Qiong Li Zhengkai Huang 2016Geodesy and Geodynamics2016,7,3:9
12Efficient manipulations of circularly polarized terahertz waves with transmissive metasurfaces显示文摘The unrestricted control of circularly polarized(CP)terahertz(THz)waves is important in science and applications,but conventional THz devices suffer from issues of bulky size and low efficiency.Although Pancharatnam-Berry(PB)metasurfaces have shown strong capabilities to control CP waves,transmission-mode PB devices realized in the THz regime are less efficient,limiting their applications in practice.Here,based on Jones matrix analysis,we design a trilayer structure(thickness of ~λ/5)and experimentally demonstrate that the structure can serve as a highly efficient transmissive meta-atom(relative efficiency of ~90%)to build PB metadevices for manipulating CP THz waves.Two ultrathin THz metadevices are fabricated and experimentally characterized with a z-scan THz imaging system.The first device can realize a photonic spin Hall effect with an experimentally demonstrated relative efficiency of ~90%,whereas the second device can generate a high-quality background-free CP Bessel beam with measured longitudinal and transverse field patterns that exhibit the nondiffracting characteristics of a Bessel beam.All the experimental results are in excellent agreement with full-wave simulations.Our results pave the way to freely manipulate CP THz beams,laying a solid basis for future applications such as biomolecular control and THz signal transportation.Min Jia Zhuo Wang Heting Li Xinke Wang Weijie Luo Shulin Sun Yan Zhang Qiong He Lei Zhou 2019Light(Science & Applications)2019,8,1:9

14Characterization of the essential role of bone morphogenetic protein 9 (BMP9) in osteogenic differentiation of mesenchymal stem cells (MSCs) through RNA interference显示文摘Mesenchymal stem cells(MSCs)are multipotent stem cells and capable of differentiating into multiple cell types including osteoblastic,chondrogenic and adipogenic lineages.We previously identified BMP9 as one of the most potent BMPs that induce osteoblastic differentiation of MSCs although exact molecular mechanism through which BMP9 regulates osteogenic differentiation remains to be fully understood.Here,we seek to develop a recombinant adenovirus system to optimally silence mouse BMP9 and then characterize the important role of BMP9 in osteogenic differentiation of MSCs.Using two different siRNA bioinformatic prediction programs,we design five siRNAs targeting mouse BMP9(or simB9),which are expressed under the control of the converging H1 and U6 promoters in recombinant adenovirus vectors.We demonstrate that two of the five siRNAs,simB9-4 and simB9-7,exhibit the highest efficiency on silencing exogenous mouse BMP9 in MSCs.Furthermore,simB9-4 and simB9-7 act synergistically in inhibiting BMP9-induced expression of osteogenic markers,matrix mineralization and ectopic bone formation from MSCs.Thus,our findings demonstrate the important role of BMP9 in osteogenic differentiation of MSCs.The characterized simB9 siRNAs may be used as an important tool to investigate the molecular mechanism behind BMP9 osteogenic signaling.Our results also indicate that recombinant adenovirus-mediated expression of siRNAs is efficient and sustained,and thus may be used as an effective delivery vehicle of siRNA therapeutics.Shujuan Yan Ruyi Zhang Ke Wu Jing Cui Shifeng Huang Xiaojuan Ji Liping An Chengfu Yuan Cheng Gong Linghuan Zhang Wei Liu Yixiao Feng Bo Zhang Zhengyu Dai Yi Shen Xi Wang Wenping Luo Bo Liu Rex C.Haydon Michael J.Lee Russell R.Reid Jennifer Moriatis Wolf Qiong Shi Hue H.Luu Tong-Chuan He Yaguang Weng 2018Genes & Diseases2018,5,2:8
15Compact plant type rice has higher lodging and N resistance under machine transplanting显示文摘To identify the major factors that contribute to the difference in lodging among different rice varieties under machine transplanting and their responses to nitrogen(N),field experiments were conducted at Danyang County(a representative eco-site of the Lower Yangtze River)in Jiangsu Province,China in 2017 and 2018,22 hybrid indica varieties(HIs),22 inbred japonica varieties(IJs)and two indica japonica hybrid varieties(IJHs)were transplanted by machine with three N rates(N0,N150 and N300,0,150 and 300 kg ha–1,respectively).Lodging-related physical parameters,morphological characteristics and apparent transport rates of dry matter were examined.Significant difference in yield was observed among different types of rice,and followed by IJsDING Chao LUO Xi-kun WU Qiong LU Bo DING Yan-feng WANG Shao-hua LI Gang-hua 2021Journal of Integrative Agriculture2021,20,1:7

18Characterisation of Neonicotinoid and Pymetrozine Resistance in Strains of Bemisia tabaci(Hemiptera:Aleyrodidae)from China显示文摘Four strains of the Q biotype and one of the B biotype of the whitefly Bemisia tabaci collected from China were characterised for resistance to four neonicotinoid insecticides and pymetrozine.Q biotype strains showed moderate to strong resistance to imidacloprid,thiamethoxam and acetamiprid,but little or no cross-resistance to dinotefuron.Resistance to neonicotinoids was consistently associated with resistance to pymetrozine,despite the latter having a distinct(though unresolved)mode of action.The single B biotype strain proved largely susceptible to all the insecticides investigated.Resistance in the Q biotype strains was associated with over-expression of a cytochrome P450 monooxygenase gene,CYP6CM1,whose substrate specificity presumably accounts for the observed cross-resistance profiles.RAO Qiong XU Yong-hua LUO Chen ZHANG Hong-yu Christopher M Jones Greg J Devine KevinGorman Ian Denholm 2012Journal of Integrative Agriculture2012,11,2:7
19Crosstalk-free achromatic full Stokes imaging polarimetry metasurface enabled by polarization-dependent phase optimization显示文摘Imaging polarimetry is one of the most widely used analytical technologies for object detection and analysis.To date,most metasurface-based polarimetry techniques are severely limited by narrow operating bandwidths and inevitable crosstalk,leading to detrimental effects on imaging quality and measurement accuracy.Here,we propose a crosstalkfree broadband achromatic full Stokes imaging polarimeter consisting of polarization-sensitive dielectric metalenses,implemented by the principle of polarization-dependent phase optimization.Compared with the single-polarization optimization method,the average crosstalk has been reduced over three times under incident light with arbitrary polarization ranging from 9μm to 12μm,which guarantees the measurement of the polarization state more precisely.The experimental results indicate that the designed polarization-sensitive metalenses can effectively eliminate the chromatic aberration with polarization selectivity and negligible crosstalk.The measured average relative errors are 7.08%,8.62%,7.15%,and 7.59%at 9.3,9.6,10.3,and 10.6μm,respectively.Simultaneously,the broadband full polarization imaging capability of the device is also verified.This work is expected to have potential applications in wavefront detection,remote sensing,light-field imaging,and so forth.Yaxin Zhang Mingbo Pu Jinjin Jin Xinjian Lu Yinghui Guo Jixiang Cai Fei Zhang Yingli Ha Qiong He Mingfeng Xu Xiong Li Xiaoliang Ma Xiangang Luo 2022Opto-Electronic Advances2022,5,11:6
20Theoretical observation of hexaatomic molecules containing pentacoordinate planar carbon显示文摘The smallest molecules up to date containing a D5h pentacoordinate planar carbon (PPC) atom, CBe5 and CBe54-, are presented by means of ab initio calculations. To gain a better understanding about which electronic factors contribute to their stabilization, natural bond orbital (NBO) analysis and the nucleus independent chemical shifts (NICS) were calculated. The data reported here suggest that D5h CBe5 is σ aromaticity in nature, while in D5h CBe54- π aromaticity is dominating. The classical octet rule is well satisfied in both molecules, and is one of the fundamental reasons to understand the stability of the pentagon structures. The Be5 ring serves as σ donor in D5h CBe5, and π-acceptor in D5h CBe54-. The D5h CBe54- possessing 18 valence electrons with a closed-shell electron configuration is the most plau-sible candidate for experimental detection.LUO Qiong State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing 100081, China 2008Science China Chemistry2008,51,11:6
