| 1 | A novel gene delivery system targeting cells expressing VEGF receptors显示文摘Two ligand oligopeptides GV1 and GV2 were designed according to the putative binding region of VEGF to its receptors. GV1, GV2 and endosome releasing oligopeptide HA20 were conjugated with poly-L-lysine or protamine and the resulting conjugates could interact with DNA in a noncovalent bond to form a complex. Using pSV2-β-galactosidase as a reporter gene, it has been demonstrated that exogenous gene was transferred into bovine aortic arch-derived endothelial cells (ABAE) andhuman malignant melanoma cell lines (A375) in vitro. In vivo experiments, exogenous gene was transferred into tumor vascular endothelial cells and tumor cells of subcutaneously transplanted human colon cancer LOVO, human malignant melanoma A375 and human hepatoma graft in nude mice. This system could also target gene to intrahepatically transplanted human hepatoma injected via portal vein in nude mice. These results are correlated with theGene delivery system targeting VEGF receptors relevant receptors (flt-1, flk-1/KDR) expression on the targeted cells and tissues. | LI JUN MIN JUN SONG HAN YI HUANG PEI KUN TIAN SHU MIN QU MIN YAO HUI QIU JIANG DA FANG WAN JING CHU LUO CHENG XIAO GU JIAN REN GU( National Labomtory for Oncogenes and Related Genes, Shanghai Cancer Institute, Shanghai 200032,China)(National Laboratory of | 1999 | Cell Research1999,9,1: | 22 |

| 6 | Passive-source ocean bottom seismograph(OBS) array experiment in South China Sea and data quality analyses显示文摘Long-term passive source ocean bottom seismograph(OBS) observatory is challenging due to various technical difficulties. In order to gain experience in this field, and to reveal the lithospheric structure beneath the extinct ridge in the central South China Sea(SCS), we carried out a passive source OBS array experiment, which includes 18 OBSs, in the deep portion of SCS. Here we present the instrumentation, the OBS deployment and recovery of this experiment, and more importantly, the data quality evaluated by a number of approaches. Through processing and inspecting waveforms from global, regional and local earthquakes, we find that most of recovered OBSs have good data quality with discernible main phases. The ambient noise analyses of OBS recordings show that their noise is higher than the global average, and the horizontal component is noisier than the vertical, indicating current impacts on horizontal components are more severe. In the period range of 5–10 s, there is a noise notch for the SCS OBSs, and noise levels of horizontal components are comparable to the vertical. This feature, which is not seen at OBS stations in open ocean, suggests the distant sources for double frequency microseism in this marginal sea are not significant. In addition, we successfully determined the orientations for 7 OBSs by investigating their Rayleigh wave polarizations; and we demonstrated the dispersion feature of Rayleigh waves through the frequency-time analysis. Finally, we summarized lessons learned from this experiment regarding the passive source OBS investigations in SCS. | Chenguang Liu Qingfeng Hua Yanliang Pei Ting Yang Shaohong Xia Mei Xue Ba Manh Le Da Huo Fang Liu Haibo Huang | 2014 | Chinese Science Bulletin2014,59,33: | 11 |
| 7 | Applying the China-PAR Risk Algorithm to Assess 10-year Atherosclerotic Cardiovascular Disease Risk in Populations Receiving Routine Physical Examinations in Eastern China显示文摘Objective To assess the 10-year Atherosclerotic Cardiovascular Disease(ASCVD) risk score among adults in eastern China using the China-PAR equation which formulated primarily for the Chinese population. Methods Data from 72,129 individuals from 35-74 years old who received routine physical examinations in eastern China were analyzed in this study. The 10-year risk scores were calculated using the China-PAR equation. The chi-square test and logistic regression were then performed to evaluate the association between the selected risk factors and overall CVD risk. Results The mean 10-year ASCVD risk scores were 3.82% ± 3.76% in men and 1.30% ± 1.65% in women based on the China-PAR equation. Overall, 20% of men and 3.5% of women were intermediate-risk, and 7.3% of men and 0.3% of women were high-risk. Waist to hip ratio(WHR) [OR = 1.16(CI 95% = 1.06-1.26)], waist to height ratio(WHtR) [OR = 1.16(CI 95% = 1.05-1.28)], non-high-density lipoprotein cholesterol(non-HDL-C) [OR = 1.23(CI 95% = 1.09-1.39)], and total cholesterol(TC)/HDL-C [OR = 1.68(CI 95% = 1.46-1.94)] were more strongly associated with CVD risk than body-mass index(BMI), waist circumference(WC), and TC alone. Conclusion Male-specific prevention and treatment strategies for ASCVD are needed in eastern China. In addition, WHR, WHtR, non-HDL-C, and TC/HDL-C which not included in the the China-PAR equation were also independently associated with 10-year ASCVD risk score categories. | LI Hui Hua HUANG Shan LIU Xing Zhen ZOU Da Jin | 2019 | Biomedical and Environmental Sciences2019,32,2: | 9 |

| 10 | Effects of yaw-roll coupling ratio on the lateral-directional departure prediction and restraint显示文摘The experimental data obtained from yaw-roll coupled wind tunnel tests are used for lateral-directional departure prediction,by linearizing the_b model to extract nominal dynamic derivatives at each coupling ratio.The prediction results are compared with those of the existing engineering methods which are based on the conventional aerodynamic derivatives.The comparison shows that the yaw-roll coupling ratio has a great influence on the departure susceptibility.The departure resistance will loss in partial region of the coupling ratio when the angle of attack is higher than a critical value.According to the stable and unstable regions of coupling ratio,a two-segment stability augmentation system with two different feedback gain matrices is obtained by pole-placement method.The two-segment stability augmentation system is used in the simulations of straight and level flight,steady turn,spin recovery and Herbst maneuver.The simulation results are also compared with the applications of a fixed-gain stability augmentation system designed by the conventional aerodynamic derivatives.When the yaw-roll coupling effects are fully considered,the two-segment stability augmentation system is more effective for departure restraint and can provide a better flying quality with less control energy. | Lin SHEN Da HUANG Genxing WU | 2019 | Chinese Journal of Aeronautics2019,32,10: | 8 |
| 11 | Effects of yaw-roll coupling ratio on lateraldirectional aerodynamic characteristics显示文摘Experimental investigation of large amplitude yaw-roll coupled oscillations was conducted in a low-speed wind tunnel using an aircraft configuration model. A special test rig was designed and constructed to provide different coupled motions from low to high angles of attack.A parameter ‘‘coupling ratio' was introduced to indicate the extent of yaw-roll coupling. At each pitch angle, seven coupling ratios were designed to study the yaw-roll coupling effects on the lateraldirectional aerodynamic characteristics systematically. At high angles of attack, the damping characteristics of yawing and rolling moments drastically varied with coupling ratios. In the coupled motions with the rotation taking place about the wind axis, the lateral-directional aerodynamic moments exhibited unsteady characteristics and were different from the ‘‘quasi-steady' results of the rotary balance tests. The calculated results of the traditional aerodynamic derivative method were also compared with the experimental data. At low and very high angles of attack, the aerodynamic derivative method was applicative. However, within a wide range of angles of attack, the calculated results of aerodynamic derivative method were inconsistent with the experimental data, due to the drastic changes of damping characteristics of lateral-directional aerodynamic moments with yaw-roll coupling ratios. | Lin SHEN Da HUANG Genxing WU | 2019 | Chinese Journal of Aeronautics2019,32,2: | 7 |

| 13 | Reactivation of a huge ancient landslide by surface water infiltration显示文摘An ancient landslide, situated in Deqin County, Yunnan Province, China, was used to investigate the reactivation by water infiltration. This study considers the infiltration process and landslide stability using finite-element method(FEM)-based models. The results show that the reactivation of old landslide deposit was triggered by the long-term leakage of diversion ditch before October 2012, and the reactivation was triggered again by the intense rainfall on 7-9 October 2012. The old cracks, which formed in the earlier reactivation of landslide, played a key role for the rainfall infiltration. They offered a preferential path for much more rainfall to infiltrate fast into deep soil, and caused wetting front to move down faster in landslide. The old slip zone with lower permeability was another important factor to cause the infiltrated water to accumulate and form a high pore water pressure above slip zone. Then the high pore water pressure decreased the shear strength of slip zone and triggered the reactivation of the old landslide deposit again. | TU Guo-xiang HUANG Da DENG Hui | 2019 | Journal of Mountain Science2019,16,4: | 6 |

| 17 | Cyclic load testing of pre-stressed rock anchors for slope stabilization显示文摘The objective of this research was to assess the characteristics of seismic induced damage and the deformation patterns of pre-stressed cement-grouted cables that are used for rock slope stabilization projects subjected to quasi-static cyclic loading.The experimental configuration includes the installation of 15 pre-stressed cables in a slope model made of concrete blocks(theoretically rigid rock mass) on top of a pre-existing sliding surface.The study showed that:(i) The pre-stressed cables exhibited great seismic performance.Rapid displacement of the model blocks was observed after the complete loss of the initial pre-stress load under continued applied cyclic loads and exceedance of the state of equilibrium,which implies the higher the initial pre-stress load,the better the seismic performance of the rock anchor;(ii) The failure of the pre-stressed cables was due to fracture at the connection of the tendons and cable heads under cyclic loading.The sequence of failure had a distinct pattern.Failure was first observed at the upper row of cables,which experienced the most severe damage,including the ejection of cable heads.No evidence of de-bonding was observed during the cyclic loading;(iii) The stress distribution of the bond length for pre-stressed cables was highly non-uniform.High stress concentrations were observed at both the fixed end and the free end of the bond length both before and immediately after the state of equilibrium is exceeded.The results obtained can be used to evaluate the overall performance of pre-stressed rock anchors subject to seismic loading and their potential as rockfall prevention and stabilization measures. | ZHENG Da LIU Fang-zhou JU Neng-pan FROST J.David HUANG Run-qiu | 2016 | Journal of Mountain Science2016,13,1: | 5 |

| 20 | An AGAMOUS-like factor is associated with the origin of two domesticated varieties in Cymbidium sinense (Orchidaceae)显示文摘Cymbidium has been artificially domesticated for centuries in Asia,which produced numerous cultivated varieties.Flowers with stamenoid tepals or those with multiple tepals have been found in different species of Cymbidium;however,the molecular basis controlling the formation of these phenotypes is still largely unknown.Previous work demonstrated that AGAMOUS/AG lineage MADS genes function in floral meristem determinacy as well as in reproductive organs development in both dicots and monocots,indicating a possible relationship with the origin of two flower varieties in Cymbidium.Here,we characterized and analyzed two AG lineage paralogues,CsAG1 and CsAG2,from Cymbidium sinense,both of which were highly expressed in the gynostemium column of a standard C.sinense.Interestingly,we detected ectopic expression of CsAG1 rather than CsAG2 in all floral organs of a stamenoid-tepal variety and significant down-regulation of CsAG1 in a variety with multiple tepals.Over-expression of CsAG1 in wild type Arabidopsis resulted in petal-to-stamen homeotic conversion,suggesting a conserved C-function of CsAG1 in the development of Cymbidium flower.Altogether,our results supported a hypothesis that disruption of a single AG-like factor would be associated with the formation of two domesticated varieties in C.sinense. | Shihao Su Xiaoyu Shao Changfa Zhu Jiayin Xu Yuhuan Tang Da Luo Xia Huang | 2018 | Horticulture Research2018,5,1: | 4 |
