1Scaling all-fiber mid-infrared supercontinuum up to 10 W-level based on thermal-spliced silica fiber and ZBLAN fiber显示文摘We demonstrate an integrated all-fiber mid-infrared(mid-IR)supercontinuum(SC)source generated by a 1.95μm master oscillator power amplifier system and a single-mode ZBLAN(ZrF_4–BaF_2–LaF_3–AlF_3–NaF)fiber.The maximum average output power is 10.67 W with spectral bandwidth covering from~1.9 to 4.1μm.The single-mode ZBLAN fiber and silica fiber are thermal-spliced to enhance the robustness and practicability of the system.It is,to the best of our knowledge,the first high-power integrated compacted all-fiber mid-IR SC source based on thermal-spliced silica fiber and ZBLAN fiber.Zhijian Zheng Deqin Ouyang Junqing Zhao Minqiu Liu Shuangchen Ruan Peiguang Yan Jinzhang Wang 2016Photonics Research2016,4,4:13
2Context Information and Fragments Based Cross-Domain Word Segmentation显示文摘A new joint decoding strategy that combines the character-based and word-based conditional random field model is proposed.In this segmentation framework,fragments are used to generate candidate Out-of-Vocabularies(OOVs).After the initial segmentation,the segmentation fragments are divided into two classes as 'combination'(combining several fragments as an unknown word) and 'segregation'(segregating to some words).So,more OOVs can be recalled.Moreover,for the characteristics of the cross-domain segmentation,context information is reasonably used to guide Chinese Word Segmentation(CWS).This method is proved to be effective through several experiments on the test data from Sighan Bakeoffs 2007 and Bakeoffs 2010.The rates of OOV recall obtain better performance and the overall segmentation performances achieve a good effect.Huang Degen Tong Deqin 2012China Communications2012,9,3:8
3Expert consensus on dental caries management显示文摘Dental Caries is a kind of chronic oral disease that greatly threaten human being’s health.Though dentists and researchers struggled for decades to combat this oral disease,the incidence and prevalence of dental caries remain quite high.Therefore,improving the disease management is a key issue for the whole population and life cycle management of dental caries.So clinical difficulty assessment system of caries prevention and management is established based on dental caries diagnosis and classification.Dentists should perform oral examination and establish dental records at each visit.When treatment plan is made on the base of caries risk assessment and carious lesion activity,we need to work out patient-centered and personalized treatment planning to regain oral microecological balance,to control caries progression and to restore the structure and function of the carious teeth.And the follow-up visits are made based on personalized caries management.This expert consensus mainly discusses caries risk assessment,caries treatment difficulty assessment and dental caries treatment plan,which are the most important parts of caries management in the whole life cycle.Lei Cheng Lu Zhang Lin Yue Junqi Ling Mingwen Fan Deqin Yang Zhengwei Huang Yumei Niu Jianguo Liu Jin Zhao Yanhong Li Bin Guo Zhi Chen Xuedong Zhou 2022International Journal of Oral Science2022,14,2:8
4A 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 2003Genomics, Proteomics & Bioinformatics2003,1,2:6
5Ginkgo biloba leaf extract improves the cognitive abilities of rats with D-galactose induced dementia显示文摘Standardized Ginkgo biloba leaf extract has been used in clinical trials for its beneficial effects on brain functions,particularly in dementia.Substantial experimental evidences indicated that Ginkgo biloba leaf extract (EGB) protected neuronal cells from a variety of insults.We investigated the effect of EGB on cognitive ability and protein kinase B (PKB) activity in hippocampal neuronal cells of dementia model rats.Rats received an intraperitoneal injection of D-galactose to induce dementia.Forty-eight Spraque-Dawley rats were randomly divided into six groups,including the control group,D-galactose group (Gal),low-dose EGB group (EGB-L),mid-dose EGB group (EGB-M),high-dose EGB group (EGB-H) and treatment group.The EGB-L,EGB-M and EGB-H groups were administered with EGB and D-galactose simultaneously.Y-maze,cresyl violet staining,TUNEL assays and immunohistochemistry staining were performed to detect learning and memory abilities,morphological changes in the hippocampus,neuronal apoptosis and the expressing level of phospho-PKB,respectively.Rats in the Gal group showed decreased abilities of learning and memory,and hippocampal pyramidal cell layer was damaged,while EGB administration improved learning and memory abilities.The Gal group exhibited many stained,condensed nuclei and micronuclei,either isolated or within the cytoplasm of cells (39.5±1.4).Apoptotic cells decreased in the groups of EGB-L (35.9±0.9),EGB-M (16.8±1.0) and EGB-H (10.1±0.8),and there were statistical significances compared with the Gal group.Immunoreactivity of phospho-PKB was localized diffusely throughout the cytosol of cells in all groups,while the immunoreactivity of the Gal group was weak.EGB significantly attenuated learning and memory impairment in a dose-dependent manner,while it could decrease the nmber of TUNEL-positive cells,and increase the activity of PKB.Our results demonstrated that EGB attenuated memory impairment and cell apoptosis in galactose-induced dementia model rats by activating PKB.Nuan Wang Xianming Chen Deqin Geng Hongli Huang Hao Zhou 2013The Journal of Biomedical Research2013,27,1:6
6An algorithm for automatic identification of multiple developmental stages of rice spikes based on improved Faster R-CNN显示文摘Spike development directly affects the yield and quality of rice. We describe an algorithm for automatically identifying multiple developmental stages of rice spikes(AI-MDSRS) that transforms the automatic identification of multiple developmental stages of rice spikes into the detection of rice spikes of diverse maturity levels. The scales vary greatly in different growth and development stages because rice spikes are dense and small, posing challenges for their effective and accurate detection. We describe a rice spike detection model based on an improved faster regions with convolutional neural network(Faster R-CNN).The model incorporates the following optimization strategies: first, Inception_Res Net-v2 replaces VGG16 as a feature extraction network;second, a feature pyramid network(FPN) replaces single-scale feature maps to fuse with region proposal network(RPN);third, region of interest(Ro I) alignment replaces Ro I pooling, and distance-intersection over union(DIo U) is used as a standard for non-maximum suppression(NMS). The performance of the proposed model was compared with that of the original Faster R-CNN and YOLOv4 models. The mean average precision(m AP) of the rice spike detection model was92.47%, a substantial improvement on the original Faster R-CNN model(with 40.96% m AP) and 3.4%higher than that of the YOLOv4 model, experimentally indicating that the model is more accurate and reliable. The identification results of the model for the heading–flowering, milky maturity, and full maturity stages were within two days of the results of manual observation, fully meeting the needs of agricultural activities.Yuanqin Zhang Deqin Xiao Youfu Liu Huilin Wu 2022The Crop Journal2022,10,5:4
7Optical properties and chemical composition of PM_(2.5) in Shanghai in the spring of 2012显示文摘The semi-diurnal mean aerosol mass concentration, chemical composition, and optical properties of PM2.5were investigated in Shanghai during the spring of 2012. Slight pollution was observed during the study period. The average PM2.5 concentration was 64.11 土 22.83(xg/m3. The mean coefficients of extinction,scattering, and absorption at 532 nm were 125.9 士 78.5,91.1 士 56.3,and 34.9 士 23.6 Mm-1, respectively. A relatively low mean single scattering albedo at 532 nm(0.73 士 0.04) and low level of elemental carbon(EC,2.67 士 1.96 |xg/m3) suggested that the light absorption was enhanced due to the internal mixing of the EC.Sulfate contributed the most to aerosol light scattering in Shanghai. The chemical composition of PM2.5was dominated by particulate organic matter, sulfate, nitrate, ammonium, and EC. Anthropogenic sources made a significant contribution to the emission and loading of the particulate pollutants. A relatively good correlation between the aerosol chemical composition and the cloud condensation nuclei(CCN) activation indicated that aerosol chemistry is an important factor that influences the saturated hygroscopicity and growth of the aerosol.Guanghan Huang Tiantao Cheng Renjian Zhang Jun Tao Chunpeng Leng Yunwei Zhang Shuping Zha Deqin Zhang Xiang Li Chunyang Xu 2014Particuology2014,12,2:4
8Scorpion venom heat-resistant protein decreases immunoreactivity of OX-42-positive microglia cells in MPTP-treated mice显示文摘BACKGROUND:Microglia function as the immune surveyors of the brain under normal physiological conditions.However,microglia become activated in response to brain injuries and immunological stimula-tion.OBJECTIVE:To explore the influence of scorpion venom(SV) heat-resistant protein on frontal cortex and hippocampal microglia cells in a mice model of Parkinson's disease.DESIGN,TIME AND SETTING:Randomized,controlled,cellular immunity study.The experiment was performed at the Physiology Department Laboratory in Dalian Medical University between June 2005 and July 2008.MATERIALS:Ninety-six healthy,C57Bl/6 mice;1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP) from Sigma,USA;SV heat-resistant protein(Experimental Base Institute in Dalian Medical University).The mice were randomly divided into four groups(n = 24):normal control,negative control,model,and SV heat-resistant protein.METHODS:Mice in the model and SV heat-resistant protein groups were subcutaneously injected with MPTP(20 mg/kg) to model Parkinson's disease,while the normal control and negative control groups were injected with physiological saline in the neck for 8 successive days.In addition,mice in the model and nor-mal control groups were intraperitoneally injected with physiological saline 2 hours following administration,while SV heat-resistant protein and negative control groups were injected SV heat-resistant protein(0.01 mg/kg).MAIN OUTCOME MEASURES:Immunoreactivity of microglia cells in MPTP-treated mice.RESULTS:Compared with normal control mice,MPTP-treated mice displayed increased OX-42 expression in the brain.However,in the SV heat-resistant protein-treated mice,OX-42 expression was decreased,com-pared to the model group.In the model mouse group,the number of OX-42-positive microglia was increased in the frontal cortex,caudatum,and hippocampal hilus,compared to the normal control mice(P < 0.01).However,in the SV heat-resistant protein-treated mice,the number of OX-42-positive microglia significantly decreased in the frontal cortex,caudatum,and hippocampal hilus,compared to the model group(P < 0.01).CONCLUSION:SV heat-resistant protein inhibited MPTP-induced microglial activation in the mouse fron-tal cortex and hippocampus,resulting in reduced microglial activation in the brain.Shengming Yin Deqin YU Xi Gao Yan Peng Yanhui Feng Jie Zhao Yiyuan Tang Wanqin Zhang 2008Neural Regeneration Research2008,3,9:4
9Increment of antioxidase activity of transgenic tobacco with betaine aldehyde dehydrogenase显示文摘Superoxide dismutase (SOD) activity in the leaves of transgenic tobacco plants with betaine aldehyde dehydrogenase (BADH) gene was about 36% higher than that in the control plants (parent plants), activities of per-oxidase (POD) and catalase (Cat) increased by about 62% and 88% respectively. Activities of ascorbate peroxidase (AsSPOD), dehydroascorbate redutase (DAsAR) and glu-tathione reductase (GR) in ascorbate-glutothion pathway located at chloroplasts increased by 67.7%, 47.9% and 38.8% respectively. These results indicated that the H2O2 produced by SOD catalyzing superoxide anion radicals (O2-) could be fully decomposed, and could not derive to form the strongest toxicant radicals · OH. This is the first report to elucidate quantitatively that the activities of two kinds of antioxidative enzymes decomposed radicals and active oxygen were matched. Photoinhibition tolerant capacity of the transgenic tobacco plants was 35% higher than that in the parent plants.

10Effect of Mesoscale Land Use Change on Characteristics of Convective Boundary Layer:Semi-Idealized Large Eddy Simulations over Northwest China显示文摘Although large-scale topography and land use have been properly considered in weather and climate models, the effect of mesoscale and microscale heterogeneous land use on convective boundary layer(CBL) has not been fully understood yet. In this study, the influence of semi-idealized strip-like patches of oases and deserts, which resemble irrigated land use in Northwest China, on the CBL characteristics, is investigated based on the Weather Research and Forecasting(WRF)-large eddy simulation(LES) driven by observed land surface data. The influences of soil water content in oases on aloft CBL flow structure, stability, turbulent kinetic energy(TKE), and vertical fluxes are carefully examined through a group of sensitivity experiments. The results show that secondary circulation(SC)/turbulent organized structures(TOS) is the strongest/weakest when soil water content in oases is close to saturation(e.g.,when the oases are irrigated). With the decrease of soil water content in oases(i.e., after irrigation), SC(TOS) becomes weak(strong) in the lower and middle CBL, the flux induced by SC and TOS becomes small(large), which has a dramatic impact on point measurement of eddy covariance(EC) fluxes. The flux induced by SC and TOS has little influence on EC sensible heat flux, but great influence on EC latent heat flux. Under this circumstance, the area averaged heat flux cannot be represented by point measurement of flux by the EC method, especially just after irrigation in oases. Comparison of imbalance ratio(i.e., contribution of SC and TOS to the total flux) reveals that increased soil moisture in oases leads to a larger imbalance ratio as well as enhanced surface heterogeneity. Moreover,we found that the soil layer configuration at different depths has a negligible impact on the CBL flux properties.Bangjun CAO Shuwen ZHANG Deqin LI Yanlin LI Linfan ZHOU Jiemin WANG 2018Journal of Meteorological Research2018,32,3:4
11Rabdosia serra alleviates dextran sulfate sodium salt-induced colitis in mice through anti-inflammation,regulating Th17/Treg balance,maintaining intestinal barrier integrity,and modulating gut microbiota显示文摘Rabdosia serra(R.serra),an important component of Chinese herbal tea,has traditionally been used to treat hepatitis,jaundice,cholecystitis,and colitis.However,the chemical composition of R.serra and its effect against colitis remain unclear.In this study,the chemical composition of the water extract of R.serra was analyzed using ultra performance liquid chromatography coupled with a hybrid linear ion trap quadrupole-orbitrap mass spectrometer(UPLC-LTQ-Orbitrap-MS).A total of 46 compounds,comprising ent-kaurane diterpenoids,flavonoids,phenolic acids,and steroids,were identified in the water extract of R.serra,and the extract could significantly alleviate dextran sulfate sodium salt-induced colitis by improving colon length,upregulating anti-inflammatory factors,downregulating proinflammatory factors,and restoring the balance of T helper 17/T regulatory cells.R.serra also preserved intestinal barrier function by increasing the level of tight junction proteins(zonula occludens 1 and occludin)in mouse colonic tissue.In addition,R.serra modulated the gut microbiota composition by increasing bacterial richness and diversity,increasing the abundance of beneficial bacteria(Muribaculaceae,Bacteroides,Lactobacillus,and Prevotellaceae_UCG-001),and decreasing the abundance of pathogenic bacteria(Turicibacter,Eubacterium_fissicatena_group,and Eubacterium_xylanophilum_group).Gut microbiota depletion by antibiotics further confirmed that R.serra alleviated colitis in a microbiota-dependent manner.Overall,our findings provide chemical and biological evidence for the potential application of R.serra in the management of colitis.Hongyi Li Yi Wang Shumin Shao Hui Yu Deqin Wang Chuyuan Li Qin Yuan Wen Liu Jiliang Cao Xiaojuan Wang Haibiao Guo Xu Wu Shengpeng Wang 2022Journal of Pharmaceutical Analysis2022,12,6:4
12Extraordinary simultaneous enhancement of the coercivity and remanence of dual alloy HRE-free Nd-Fe-B sintered magnets by post-sinter annealing显示文摘Post-sinter annealing process plays an important role in the microstructures and magnetic properties of the Nd-Fe-B sintered magnets.In this paper,systematically investigated are the magnetic properties and microstructures of the as-sintered and post-sinter annealed Nd-Fe-B magnets with Pr-Fe-Ga boundary addition.Two choice consecutive annealing methods are adopted at high and low temperatures,namely the 1 st annealing at 880℃ for 2 h and then the 2^(nd) annealing at 440℃ for 3 h.It is exceptional to find out that both the remanence and coercivity are improved after 2^(nd) annealing process for this type of magnet.The coercivity is hugely increased from 10.09 kOe for the as-sintered sample to 17.19 kOe for the 2^(nd) annealed magnet,with a significant increment of 70.37%in coercivity.The extraordinary magnetic properties of B_(r)=14.44 kGs,H_(cj)=17.19 kOe and(BH)_(max)=51.08 MGOe are obtained for the designated Nd-Fe-B sintered magnets without heavy rare earth(HRE)elements manufactured by dual alloy method.The Curie temperature is monotonically decreased from 634 K to 602 K while the c-axis alignment degree is optimized after annealing.Microstructural observation and analysis indicate that the elemental distribution patterns are altered after the 2^(nd) annealing.The diffusion of the aggregate(Pr,Nd,Cu,Ga)-rich phase from triple junctions into the grain boundary regions is ascribed to the formation of thin and continuous grain boundary layer,which is critical to improve the microstructures and magnetic properties.Qingfang Huang Qingzheng Jiang Jifan Hu Sajjad Ur Rehman Gang Fu Qichen Quan Jixiang Huang Deqin Xu Dakun Chen Zhenchen Zhong 2022Journal of Materials Science & Technology2022,,11:3
130.33 mJ, 104.3 W dissipative soliton resonance based on a figure-of-9 double-clad Tm-doped oscillator and an all-fiber MOPA system显示文摘We demonstrate, for the first time, to the best of our knowledge, an all-fiber figure-of-9 double-clad Tm-doped fiber laser operating in the dissipative soliton resonance(DSR) regime. Stable mode-locked rectangular pulses are obtained by using the nonlinear amplifying loop mirror(NALM) technique. A long spool of high-nonlinearity fiber(HNLF) and a segment of SMF-28 fiber are used to enhance the nonlinearity of the NALM loop and to obtain a large all-anomalous regime. Output power and pulse energy are further boosted by using a three-stage master oscillator power amplifier(MOPA) system. At the maximum pump power, average output power of up to 104.3 W with record pulse energy of 0.33 mJ is achieved with a 2 μm DSR-based MOPA system.Zhijian Zheng Deqin Ouyang Xikui Ren Jinzhang Wang Jihong Pei Shuangchen Ruan 2019Photonics Research2019,7,5:3

15Detection and tracking of pigs in natural environments based on video analysis显示文摘Detection and tracking of pigs are important for analyzing pig behavior using computer vision.However,in natural environments,illumination changes,complex scenes,adhesion,occlusion,and individual identification from multiple objects are challenges for detection and tracking.This paper provided an anti-interference algorithm for pig detection and tracking based on video analysis.Firstly,pigs were recognized in natural environment based on color information,and noises were removed based on the analysis of connected regions in the binary images.Secondly,multiple pigs were separated by contours and edges.Thirdly,pigs were tracked based on a set of association rules with constraint items(DT-ACR).When DT-ACR fails,targets that are not lost were tracked continuously,while lost targets were retrieved in the nearby location,which effectively increased the duration of tracking.Experiments showed that the algorithm was able to track each individual pig in the following conditions:no-light scenes,sun glint scenes,adhesion scenes and occlusion scenes.The overall tracking accuracy reached up to 87.32%(83.85%for serious adhesion,87.4% for occlusion,82.4% for strong light,82.17% for no light and dark,96.58%for 2 pigs,88.33%for 3 pigs and 77.63 for 4 pigs).A pig activity analysis study based on the pig detection and tracking algorithm was carried out,and the results showed that the proposed method was able to track pigs for a long period of time and extract the values that reflected pigs’movements.Deqin Xiao Aijing Feng Jian Liu 2019International Journal of Agricultural and Biological Engineering2019,12,4:2
16A distinct D1-MSN subpopulation down-regulates dopamine to promote negative emotional state显示文摘Dopamine(DA)level in the nucleus accumbens(NAc)is critical for reward and aversion encoding.DA released from the ventral mesencephalon(VM)DAergic neurons increases the excitability of VM-projecting D1-dopamine receptor-expressing medium spiny neurons(D1-MSNs)in the NAc to enhance DA release and augment rewards.However,how such a DA positive feedback loop is regulated to maintain DA homeostasis and reward-aversion balance remains elusive.Here we report that the ventral pallidum(VP)projection of NAc D1-MSNs(D1^(NAc-VP))is inhibited by rewarding stimuli and activated by aversive stimuli.In contrast to the VM projection of D1-MSN(D1^(NAc-VM)),activation of D1^(NAc-VP) projection induces aversion,but not reward.D1^(NAc-VP) MSNs are distinct from the D1^(NAc-VM) MSNs,which exhibit conventional functions of D1-MSNs.Activation of D1^(NAc-VP) projection stimulates VM GABAergic transmission,inhibits VM DAergic neurons,and reduces DA release into the NAc.Thus,D1^(NAc-VP) and D1^(NAc-VM) MSNs cooperatively control NAc dopamine balance and reward-aversion states.Zhiyuan Liu Qiumin Le Yanbo Lv Xi Chen Jian Cui Yiming Zhou Deqin Cheng Chaonan Ma Xiujuan Su Lei Xiao Ruyi Yang Jiayi Zhang Lan Ma Xing Liu 2022Cell Research2022,32,2:2

18Disaggregating population data for assessing progress of SDGs:methods and applications显示文摘Rapid population growth has had a significant impact on society,economy and environment,which will challenge the achievement of the United Nations Sustainable Development Goals(SDGs).Spatially accurate and detailed population distribution data are essential for measuring the impact of population growth and tracking progress on the SDGs.However,most population data are evenly distributed within administrative units,which seriously lacks spatial details.There are scale differences between the population statistical data and geospatial data,which makes data analysis and needed research difficult.The disaggregation method is an effective way to obtain the spatial distribution of population with greater granularity.It can also transform the statistical population data from irregular administrative units into regular grids to characterize the spatial distribution of the population,and the original population count is preserved.This paper summarizes the research advances of population disaggregation in terms of methodology,ancillary data,and products and discusses the role of spatial disaggregation of population statistical data in monitoring and evaluating SDG indicators.Furthermore,future work is proposed from two perspectives:challenges with spatial disaggregation and disaggregated population as an Essential SDG Variable(ESDGV).Yue Qiu Xuesheng Zhao Deqin Fan Songnian Li Yijing Zhao 2022International Journal of Digital Earth2022,15,1:1

20Complete Genome Sequences of the SARS-CoV: the BJ Group (Isolates BJ01-BJ04)显示文摘Beijing has been one of the epicenters attacked most severely by the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) since the first patient was diagnosed in one of the city's hospitals. We now report complete genome sequences of the BJ Group, including four isolates (Isolates B J01, B J02, B J03,and B J04) of the SARS-CoV. It is remarkable that all members of the BJ Group share a common haplotype, consisting of seven loci that differentiate the group from other isolates published to date. Among 42 substitutions uniquely identifled from the BJ group, 32 are non-synonymous changes at the amino acid level.Rooted phylogenetic trees, proposed on the basis of haplotypes and other sequence variations of SARS-CoV isolates from Canada, USA, Singapore, and China, gave rise to different paradigms but positioned the BJ Group, together with the newly discovered GD01 (GD-Ins29) in the same clade, followed by the H-U Group (from Hong Kong to USA) and the H-T Group (from Hong Kong to Toronto), leaving the SP Group (Singapore) more distant. This result appears to suggest a possible transmission path from Guangdong to Beijing/Hong Kong, then to other countries and regions.ShengliBi E‘deQin ZuyuanXu WeiLi JingWang YongWuHu YongLiu ShuminDuan JianfeiHu YujunHan JingXu YanLi YaoYi YongdongZhou WeiLin1 JieWen HongXu RuanLi ZizhangZhang HaiyanSun JinguiZhu ManYu BaochangFan QingfaWu WeiLin2 LinTang Bao’anYang GuoqingLi WenmingPeng WenjieLi TaoJiang YajunDeng BohuaLiu JianpingShi YongqiangDeng WeiWei HongLiu ZongzhongTong FengZhang YuZhang Cui‘eWang YuquanLi JiaYe YonghuaGan JiaJi XiaoyuLi XiangjunTian FushuangLu GangTan RuifuYang BinLiu SiqiLiu SonggangLi JunWang JianWang WuchunCao JunYu XiaopingDong HuanmingYang 2003Genomics, Proteomics & Bioinformatics2003,1,3:1
