| 3 | The presence of phosphorylation form of D1 protein in its cross-linked aggregates in high light treated spinach leaves in vivo显示文摘In the present study, using specific antibody against D1 protein, we detected four ag- gregates of D1 protein in thylakoid membranes from spinach leaves illuminated at high light (800―2500 μmol photons·m?2·s?1) for 3 h. Their accumulations were dependent on the light intensity to which the leaves had been subjected. Further immunoblot analysis indicated that 70 kD aggregate was a prod- uct of D1 protein cross-linked with CP43, 65 and 60 kD aggregate were two cross-linked products be- tween D1 and D2 proteins, and 41 kD aggregate was one cross-linked D1 with α-subunit of cytochrome b559 (Cyt b559). This result provided the evidence for the existence of the aggregation of the D1 protein in vivo. The maximal level of D1/Cyt b559 aggregate occurred at 1000 μmol photons·m?2·s?1 but drastically decreased with further increasing light intensity. Im- munoblot analysis with phosphothreonine (Thr (P)) antibody indicated that D1/CP43 and D1/Cyt b559 aggregates contained the phosphorylated protein(s). In vitro dephosphorylation experiment also showed that D1/Cyt b559 and D1/CP43 aggregates lost the immunoreactivity with Thr (P) antibody after the phosphatase treatment of the membranes from high-light-illuminated leaves. Our results demon- strated that strong illumination of spinach leaves in- duced cross-linked products of D1 protein with its nearby polypeptides of PS Ⅱ , some of which con- tained the phosphorylated D1 protein. | WEI Huimin GUO Junwei ZHANG Shuang HUANG Bo LIU Yinqiu DU Linfang | 2006 | Chinese Science Bulletin2006，51，1： | 12 |
| 4 | Chemical fingerprint analysis of Gentianae Radix et Rhizoma by high-performance liquid chromatography显示文摘Gentianae Radix et Rhizoma(also called 'Longdan' in Chinese)is commonly used for eliminating damp-heat and quenching the fire of liver and gall bladder in traditional Chinese medicine.In this study,a novel and reliable method using high-performance liquid chromatography(HPLC)was developed both for quantitative analysis of four bioactive compounds(loganic acid,swertiamarin,gentiopicroside and sweroside)and chemical fingerprint analysis of 'Longdan'.In quantitative analysis,four compounds showed good regressions(R^(2)>40.9987)within the test ranges and the recovery of the method was in the range 97.61-102.49%.In fingerprint analysis,ten characteristic peaks were selected to evaluate the similarities of the crude drugs,and the HPLC chromatograms of twenty samples from different regions of China showed similar patterns.The results demonstrated that the combination of the quantitative and chromatographic fingerprint analyses offered an efficient way to evaluate the quality consistency of Gentianae Radix et Rhizoma. | Baozhong Duan Jianyong Hu Linfang Huang Xianying Yang Fuying Chen | 2012 | Acta Pharmaceutica Sinica B2012，2，1： | 8 |

| 6 | Energy-balanced multiple-sensor collaborative scheduling for maneuvering target tracking in wireless sensor networks显示文摘An energy-balanced multiple-sensor collaborative scheduling is proposed for maneuvering target tracking in wireless sensor networks (WSNs). According to the position of the maneuvering target, some sensor nodes in WSNs are awakened to form a sensor cluster for target tracking collaboratively. In the cluster, the cluster head node is selected to implement tracking task with changed sampling interval. The distributed interactive multiple model (IMM) filter is employed to estimate the target state. The estimation accuracy is improved by collaboration and measurement information fusion of the tasking nodes. The balanced distribution model of energy in WSNs is constructed to prolong the lifetime of the whole network. In addition, the communication energy and computation resource are saved by adaptively changed sampling intervals, and the real-time performance is satisfactory. The simulation results show that the estimation accuracy of the proposed scheme is improved compared with the nearest sensor scheduling scheme (NSSS) and adaptive sensor scheduling scheme (ASSS). Under satisfactory estimation accuracy, it has better performance in saving energy and energy balance than the dynamic collaborative scheduling scheme (DCSS). | Liu, Yonggui Xu, Bugong Feng, Linfang | 2011 | 控制理论与应用(英文版)2011，9，1： | 7 |
| 7 | A Genome Sequence of Novel SARS-CoV Isolates: the Genotype, GD-Ins29, Leads to a Hypothesis of Viral Transmission in South China显示文摘We report a complete genomic sequence of rare isolates (minor genotype) of theSARS-CoV from SARS patients in Guangdong, China, where the first few casesemerged. The most striking discovery from the isolate is an extra 29-nucleotidesequence located at the nucleotide positions between 27,863 and 27,864 (referredto the complete sequence of B J01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream ofthe N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29,suggests a significant genetic event and differentiates it from the previously re-ported genotype, the dominant form among all sequenced SARS-CoV isolates. A17-nt segment of this extra sequence is identical to a segment of the same size intwo human mRNA sequences that may interfere with viral genome replication andtranscription in the cytosol of the infected cells. It provides a new avenue for theexploration of the virus-host interaction in viral evolution, host pathogenesis, andvaccine development. | E‘deQin XiongleiHe WeiTian YongLiu WeiLi JieWen BingyinSi YongwuHu WenmingPeng LinTaug TaoJiang JianpingShi JiaJia YuZhang JiaYe Cui’eWang YujunHan JingqiangWang BaochangFan QingfaWu GuohuiChang WuchunCao ZuyuanXu RuifuYang JmgWang ManYu YanLi JingXu JunZhou YajumDeng XiaoyuLi JianfeiHu CaipingWang ChunxiaYan QingrunZhang JingyueBao GuoqingLi HaiqingZhang YilinZhang HuiZhao XiaoweiZhang ShuangliLi XiaoJieCheng XiuqingZhang BinLiu ChangqingZeng HuanmingYang WeijunChen LinFang ChangfengLi MengLei DaweiLi WeiTong XiangjunTian JianWang BoZhang SonggangLi XuehaiTan SiqiLiu WeiDong JunWang GaneKa-ShuWong JunYu QingyuZhu | 2003 | Genomics, Proteomics & Bioinformatics2003，1，2： | 6 |
| 8 | Rational development of a human antibody cocktail that deploys multiple functions to confer Pan-SARS-CoVs protection显示文摘Structural principles underlying the composition and synergistic mechanisms of protective monoclonal antibody cocktails are poorly defined.Here,we exploited antibody cooperativity to develop a therapeutic antibody cocktail against SARS-CoV-2.On the basis of our previously identified humanized cross-neutralizing antibody H014,we systematically an a lyzed a fully human n aive antibody library and rationally identified a potent neutralizing antibody partner,P17,which confers effective protection in animal model.Cryo-EM studies dissected the nature of the P17 epitope,which is SARS-CoV-2 specific and distinctly different from that of HOI4.High-resolution structure of the SARS-CoV-2 spike in complex with HOM and P17,together with functional investigations revealed that in a two-antibody cocktail,synergistic neutralization was achieved by S1 shielding and conformational locking,thereby blocking receptor attachment and viral membrane fusion,conferring high potency as well as robustness against viral mutation escape.Furthermore,cluster analysis identified a hypothetical 3rd antibody partner for further reinforcing the cocktail as pan-SARS-CoVs therapeutics. | Hangping Yao Yao Sun Yong-Qiang Deng Nan Wang Yongcong Tan Na-Na Zhang Xiao-Feng Li Chao Kong Yan-Peng Xuc Qi Chen Tian-Shu Cao Hui Zhao Xintian Yan Lei Cao Zhe Lv Dandan Zhu Rui Feng Nanping Wu Wenhai Zhang Yuhao Hu Keda Chen Rong-Rong Zhang Qingyu Lv Shihui Sun Yunhua Zhou Run Yan Guan Yang Xinglu Chanjuan Liu Xiangyun Lu Linfang Cheng Hongying Qiu Xing-Yao Huang Tianhao Weng Danrong Shi Weidong Jiang Junbin Shao Lei Wang Jie Zhang Tao Jiang Guojun Lang Cheng-Feng Qinc Lanjuan Li Xiangxi Wang | 2021 | Cell Research2021，31，1： | 5 |

| 10 | Effects of temperature on the expression of STN7 andphosphorylation of LHCII proteins in Arabidopsis thaliana显示文摘In Arabidopsis thaliana, STN7 kinase is required for phosphorylation of LHCII and for state transitions. In this paper, a hydrophilic polypeptide, derived from the amino acid sequence of STN7, was conjugated to a carrier protein, bovine serum albumin (BSA), to obtain the polyclonal antibody. Immunogenicity and specificity of the polyclonal antibody were evaluated by agar gel immunodiffusion (AGID) test and Western blot analysis. The results show that besides the phosphorylation of LHCII proteins, also the expression of STN7 was regulated by temperature conditions. In addition, the change tendency of LHCII proteins phosphorylation was not only coherent with expression of STN7 with respect to increasing temperature, but also closely related to state transitions. These results would provide useful information for studying regulatory mechanism of LHCII proteins phosphorylation and expression of STN7. | HU Yuan GAO Xiu JIANG JiaHong RAN Yan DU LinFang | 2008 | Chinese Science Bulletin2008，53，17： | 4 |

| 12 | Controlled growth and photoluminescence of highly oriented arrays of ZnO nanocones with different diameters显示文摘Large-scale oriented ZnO nanocone arrays were directly grown on zinc substrate through a hydro-thermal reaction of Zn foil with aqueous butylamine solution(3 mol/L) at 100-180 ℃ for 12 h.The syn-thesized products were characterized with X-ray diffraction,Raman spectrum,scanning electron mi-croscopy and transmission electron microscopy.The results showed that the ZnO nanocones were single crystalline with the wurtzite structure and grown along the [0001] direction.The diameter of nanocones is decreased with increasing the reaction temperature.A possible growth mechanism was also proposed to account for the formation of the ZnO nanocone arrays.The photoluminescence spectra of the ZnO nanocone arrays were studied at room temperature,two UV emission bands at 377 and 396 nm assigned to free exciton emission and exciton-exciton collision,respectively,and phonon replicas associated with 2-E2 phonon were observed in the PL spectra. | MA JunHu YANG HeQing SONG YuZhe LI Li XIE XiaoLi LIU RuiNi WANG LinFang | 2009 | Science China(Technological Sciences)2009，52，5： | 4 |
| 13 | Osteoimmunology: memorandum for rheumatologists显示文摘Rapid progress has been made in exploring the connections between the skeletal system and the immune system over the past decade. Bone tissue forms developmental niches for hematopoietic stem cells, and activated immune cells are involved in bone metabolism regulation and are potent mediators of osteoporosis and bone erosion under pathological conditions. The interdisciplinary field of osteoimmunology has emerged to pool the knowledge of the interdependence of these two systems, including the shared ligands and receptors, their crosstalk and interaction, and common intracellular signaling pathways with bidirectional influence. The receptor activator of nuclear factor-kappa B(RANK)/RANK ligand(RANKL)/osteoprotegerin(OPG) triad is the key vinculum, with multifaceted potency, being not only essential for osteoclastogenesis but also critical for lymph node organogenesis and lymphopoiesis as well as for immune regulation. In this review, we summarize the progress in this area, focusing on those aspects of interest concerning rheumatic diseases. | Lidan Zhao Linfang Huang Xuan Zhang | 2016 | Science China(Life Sciences)2016，59，12： | 3 |

| 16 | Clear mortality gap caused by graft macrosteatosis in Chinese patients after cadaveric liver transplantation显示文摘Background:Liver transplantation(LT)is one of the most effective surgical treatment for patients with end-stage liver disease.Steatosis is a contributor for inferior graft quality.But its impact and safety on transplantation was less assessed in Chinese patients.Methods:Graft steatosis and related information involved in recipients,donors and surgical procedures were retrospectively collected from 239 patients.Results:Donor macrosteatosis(MaS)caused about 2.14 and 2.80 folds of increment on patient and graft mortality.Dose-response analysis revealed prominent risk of grafts on overall patient/organ mortality when MaS content exceeded 10%(P<0.05).Noteworthy,deaths were only observed in MaS group when concurrent with extremely higher post-transplant alanine aminotransferase(ALT,64%).However,microsteatosis(MiS)grafts didn’t affect outcomes after LT.In a cohort of Chinese patients,MaS had comprehensive effects on post-transplant outcomes with relatively lower safety threshold at 10%.Mortality gap caused by MaS grafts was observed in patients with severer ischemia reperfusion injury.Conclusions:Our study revealled the graft MaS affected the post-transplant outcomes in lower risk cutoff in Chinese patients.Further study is worthy to validate these results and investigate inner mechanism under the phenomenon. | Zhengtao Liu Wenchao Wang Li Zhuang Jingfeng Liu Shuping Que Dan Zhu Linfang Dong Jian Yu Lin Zhou Shusen Zheng | 2020 | Hepatobiliary Surgery and Nutrition2020，9，6： | 2 |
| 17 | Silicon substrate-integrated hollow waveguide for miniaturized optical gas sensing显示文摘Gas sensors have a wide variety of applications.Among various existing gas sensing technologies,optical gas sensors have outstanding advantages.The development of the Internet of Things and consumer electronics has put stringent requirements on miniaturized gas sensing technology.Here,we demonstrate a chip-scale silicon substrate-integrated hollow waveguide(Si-iHWG) to serve as an optical channel and gas cell in an optical gas sensor.It is fabricated through silicon wafer etching and wafer bonding.The Si-i HWG chip is further assembled with an off-chip light source and detector to build a fully functional compact nondispersive infrared(NDIR) CO_(2) sensor.The chip size is 10 mm × 9 mm,and the dimension of the sensor excluding the microcontroller board is 50 mm × 25 mm × 16 mm.This chip solution with compactness,versatility,robustness,and low cost provides a cost-effective platform for miniaturized optical sensing applications ranging from air quality monitoring to con-sumer electronics. | SHAONAN ZHENG HONG CAI LINFANG XU NANXI LI ZHONGHUA GU YAO ZHANG WEIGUO CHEN YANYAN ZHOU QINGXIN ZHANG LENNON YAO TING LEE | 2022 | Photonics Research2022，10，1： | 2 |
| 18 | Risk stratification in symptomatic intracranial atherosclerotic disease with conventional vascular risk factors and cerebral haemodynamics显示文摘Background and purpose Symptomatic intracranial atherosclerotic stenosis(sICAS)is associated with a considerable risk of recurrent stroke despite contemporarily optimal medical treatment.Severity of luminal stenosis in sICAS and its haemodynamic significance quantified with computational fluid dynamics(CFD)models were associated with the risk of stroke recurrence.We aimed to develop and compare stroke risk prediction nomograms in sICAS,based on vascular risk factors and these metrics.Methods Patients with 50%-99%sICAS confirmed in CT angiography(CTA)were enrolled.Conventional vascular risk factors were collected.Severity of luminal stenosis in sICAS was dichotomised as moderate(50%-69%)and severe(70%-99%).Translesional pressure ratio(PR)and wall shear stress ratio(WSSR)were quantified via CTA-based CFD modelling;the haemodynamic status of sICAS was classified as normal(normal PR&WSSR),intermediate(otherwise)and abnormal(abnormal PR&WSSR).All patients received guideline-recommended medical treatment.We developed and compared performance of nomograms composed of these variables and independent predictors identified in multivariate logistic regression,in predicting the primary outcome,recurrent ischaemic stroke in the same territory(SIT)within 1 year.Results Among 245 sICAS patients,20(8.2%)had SIT.The D2H2A nomogram,incorporating diabetes,dyslipidaemia,haemodynamic status of sICAS,hypertension and age≥50 years,showed good calibration(P for Hosmer-Lemeshow test=0.560)and discrimination(C-statistic 0.73,95%CI 0.60 to 0.85).It also had better performance in risk reclassification and provided larger net benefits in decision curve analysis,compared with nomograms composed of conventional vascular risk factors only,and plus the severity of luminal stenosis in sICAS.Sensitivity analysis in patients with anterior-circulation sICAS showed similar results.Conclusions The D2H2A nomogram,incorporating conventional vascular risk factors and the haemodynamic significance of sICAS as assessed in CFD models,could be a useful tool to stratify sICAS patients for the risk of recurrent stroke under contemporarily optimal medical treatment. | Xuan Tian Hui Fang Linfang Lan Hing Lung Ip Jill Abrigo Haipeng Liu Lina Zheng Florence S Y Fan Sze Ho Ma Bonaventure Ip Bo Song Yuming Xu Jingwei Li Bing Zhang Yun Xu Yannie O Y Soo Vincent Mok Ka Sing Wong Thomas W Leung Xinyi Leng | 2023 | Stroke & Vascular Neurology2023，8，1： | 2 |
| 19 | Packet delay analysis on IEEE 802.11 DCF under finite load traffic in multi-hop ad hoc networks显示文摘In this paper, the average packet delay on IEEE 802.11 DCF under finite load traffic in multi-hop ad hoc networks is analyzed. We employ a Markov chain model to analyze the probability of transmission at each node in an arbitrary slot and derive the channel access delay. We model each node using an M/G/1 queue and derive the queueing delay. The model is extended from analyzing the single-hop average packet delay to evaluating the end-to-end packet delay in multi-hop ad hoc net-works without assuming the traffic to be in a saturation state. To validate our ana-lytic results, we have done extensive simulation. The analytic and the simulation results match very well. | DONG LinFang SHU YanTai CHEN HaiMing MA MaoDe | 2008 | Science in China(Series F)2008，51，4： | 2 |
