| 1 | Laparoscopic Partial Nephrectomy With Segmental Renal Artery Clamping:Technique and Clinical Outcomes显示文摘Background:Warm ischemic injury is one of the most important factors affecting renal function in partial nephrectomy(PN).The technique of segmental renal artery clamping emerges as an alternative to conventional renal artery clamping for renal hilar control.Objective:To evaluate the feasibility and efficiency of laparoscopic PN(LPN) with segmental renal artery clamping in comparison with the conventional technique.Design,setting,and participants:A total of 75 patients underwent LPN from June 2007 to November 2009.All patients had T1a or T1b tumor in one kidney and a normal contralateral kidney.Thirty-seven patients underwent surgeries with main renal artery clamping,and 38 underwent surgeries with segmental artery clamping.Intervention:All procedures were performed by the same laparoscopic surgeon.Measurements:Blood loss,operation time,warm ischemia(WI) time,and complications affected renal function before and after operation were recorded.Results and limitations:All LPNs were completed without conversion to open surgery or nephrectomy.The novel technique slightly increased WI time(p < 0.001) and intraoperative blood loss(p = 0.006),while it provided better postoperative affected renal function(p < 0.001) compared with the conventional technique.The total complication rate was 12%.Among the 38 cases where segmental renal artery clamping was performed,7 had to convert to the conventional method.Tumor size and location influenced the number of clamped segmental arteries.Long-term postoperative renal function is still awaited.Conclusions:LPN with segmental artery clamping is safe and feasible in clinical practice.It minimizes the intraoperative WI injury and improves early postoperative affected renal function compared with main renal artery clamping.(C) 2010 European Association of Urology.Published by Elsevier B.V.All rights reserved. | Shao,P.F.

| 2 | Massive individual orbital angular momentum channels for multiplexing enabled by Dammann gratings显示文摘Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods.Orbital angular momentum(OAM)in optical vortex beams offers a new degree of freedom and the potential to increase the capacity of free-space optical communication systems,with OAM beams acting as information carriers for OAM division multiplexing(OAM-DM).We demonstrate independent collinear OAM channel generation,transmission and simultaneous detection using Dammann optical vortex gratings(DOVGs).We achieve 80/160 Tbit s^(-1) capacity with uniform power distributions along all channels,with 1600 individually modulated quadrature phase-shift keying(QPSK)/16-QAM data channels multiplexed by 10 OAM states,80 wavelengths and two polarizations.DOVG-enabled OAM multiplexing technology removes the bottleneck of massive OAM state parallel detection and offers an opportunity to raise optical communication systems capacity to Pbit s^(-1) level. | Ting Lei Meng Zhang Yuru Li Ping Jia Gordon Ning Liu Xiaogeng Xu Zhaohui Li Changjun Min Jiao Lin Changyuan Yu Hanben Niu Xiaocong Yuan | 2015 | Light(Science & Applications)2015，4，1： | 47 |

| 6 | Endocrine role of bone in the regulation of energy metabolism显示文摘Bone mainly functions as a supportive framework for the whole body and is the major regulator of calcium homeostasis and hematopoietic function.Recently,an increasing number of studies have characterized the significance of bone as an endocrine organ,suggesting that bone-derived factors regulate local bone metabolism and metabolic functions.In addition,these factors can regulate global energy homeostasis by altering insulin sensitivity,feeding behavior,and adipocyte commitment.These findings may provide a new pathological mechanism for related metabolic diseases or be used in the diagnosis,treatment,and prevention of metabolic diseases such as osteoporosis,obesity,and diabetes mellitus.In this review,we summarize the regulatory effect of bone and bone-derived factors on energy metabolism and discuss directions for future research. | Ruoyu Zhou Qiaoyue Guo Ye Xiao Qi Guo Yan Huang Changjun Li Xianghang Luo | 2021 | Bone Research2021，9，4： | 11 |
| 7 | An efficient methodology for utilization of K-feldspar and phosphogypsum with reduced energy consumption and CO2 emissions显示文摘The issues of reducing CO_2 emissions, sustainably utilizing natural mineral resources, and dealing with industrial waste offer challenges for sustainable development in energy and the environment. We propose an efficient methodology via the co-reaction of K-feldspar and phosphogypsum for the extraction of soluble potassium salts and recovery of SO_2 with reduced CO_2 emission and energy consumption. The results of characterization and reactivity evaluation indicated that the partial melting of K-feldspar and phosphogypsum in the hightemperature co-reaction significantly facilitated the reduction of phosphogypsum to SO_2 and the exchange of K^+(K-feldspar) with Ca^(2+)(CaSO_4 in phosphogypsum). The reaction parameters were systematically investigated with the highest sulfur recovery ratio of ~ 60% and K extraction ratio of ~ 87.7%. This novel methodology possesses an energy consumption reduction of ~ 28% and CO_2 emission reduction of ~ 55% comparing with the present typical commercial technologies for utilization of K-feldspar and the treatment of phosphogypsum. | Zhixi Gan Zheng Cui Hairong Yue Siyang Tang Changjun Liu Chun Li Bin Liang Heping Xie | 2016 | Chinese Journal of Chemical Engineering2016，24，11： | 11 |
| 8 | Global Fine Registration of Point Cloud in LiDAR SLAM Based on Pose Graph显示文摘The laser scanning system based on Simultaneous Localization and Mapping(SLAM)technology has the advantages of low cost,high precision and high efficiency.It has drawn wide attention in the field of surveying and mapping in recent years.Although real-time data acquisition can be achieved using SLAM technology,the precision of the data can’t be ensured,and inconsistency exists in the acquired point cloud.In order to improve the precision of the point cloud obtained by this kind of system,this paper presents a hierarchical point cloud global optimization algorithm.Firstly,the“point-to-plane”iterative closest point(ICP)algorithm is used to match the overlapping point clouds to form constraints between the trajectories of the scanning system.Then a pose graph is constructed to optimize the trajectory.Finally,the optimized trajectory is used to refine the point cloud.The computational efficiency is improved by decomposing the optimization process into two levels,i.e.local level and global level.The experimental results show that the RMSE of the distance between the corresponding points in overlapping areas is reduced by about 50%after optimization,and the internal inconsistency is effectively eliminated. | Li YAN Jicheng DAI Junxiang TAN Hua LIU Changjun CHEN | 2020 | Journal of Geodesy and Geoinformation Science2020，3，2： | 9 |
| 9 | Experimental measurement of the electrical conductivity of single crystal olivine at high temperature and high pressure under different oxygen fugacities显示文摘At 1.0-4.0 GPa and 1123-1473 K and under oxygen fugacity-controlled conditions (Ni + NiO, Fe + Fe3O4, Fe + FeO and Mo+ M0O2 buffers), a YJ-3000t Model six-anvil solid high-pressure apparatus and a Sarltron-1260 Impedance/Gain-Phase analyzer were employed to conduct an in situ measurement of the electrical conductivity of single crystal olivine. Experimental results showed that: (1) within the range of experimentally selected frequencies (103-106 Hz), the electrical conductivity of the sample is of great dependence on the frequency; (2) with the rise of temperature ( T), the electrical conductivity (σ) will increase, and the Arrenhius linear relationship is established between lgσ and 1/T; (3) under the control of oxygen buffer Fe+ Fe3O4, with the rise of pressure, the electrical conductivity tends to decrease whereas the activation enthalpy and independent-of-temperature preexponential factor tend to increase, with the activation energy and activation volume of the sample estimated at (1. 25 ± 0.08) eV and (0.105 ±0.025) cm3/mol, respectively; (4) under given pressure and temperature conditions, the electrical conductivity tends to increase whereas the activation energy tends to decrease with increasing oxygen fugacity; and ( 5) the mechanism of electrical conduction of small polarons can provide insight into the behavior of electrical conduction of olivine under high pressure and high temperature. | DAI Lidong LI Heping LIU Congqiang CUI Tongdi SHAN Shuangming YANG Changjun LIU Qingyou DENG Heming | 2006 | Progress in Natural Science:Materials International2006，16，4： | 9 |
| 10 | Effect of total aluminum concentration on the formation and transformation of nanosized Al_(13) and Al_(30) in hydrolytic polymeric aluminum aqueous solutions显示文摘Influence of total aluminum concentration (CAlT) on the generation and transformation of nanosized Al13 and Al30 in hydrolytic polyaluminum aqueous solutions was in-vestigated using high field 27Al NMR and time-developed Al-Ferron complex colorimetry. When prepared at the opti-mal basicity (B) of Al13 generation and 80℃, the Al13 species in polyaluminum solution tends to further polymerize and convert to Al30 and higher polymers when CAlT >0.2 mol·L?1, but Al13 does not convert to Al30 quantificationally, as the formation of Alu from Al13 and Al30 is accelerated in the same way. The conversion rate of Al13 is accelerated by the in-crease in CAlT. When CAlT >0.75 mol·L?1, Al13 content de-creases rapidly, and Al30 content increases continuously and becomes the dominant nanometer polynuclear aluminum species. Alm is one of prerequisites of Al13 conversion to Al30. When CAlT increases and B reduces, the polymerization rate between Al13 and Alm increases, and at the same time, the dissociation reaction rate of Al13 and Al30 by H+ also increases. The latter becomes the dominant reaction in polyaluminum solution with low B value, so Al30 decreases with the increas-ing CAlT. The hydrolytic polyaluminum solution with Al13 content beyond 80% can only be prepared under the condi-tion of CAlT<0.5 mol·L?1 and optimal B value. | CHEN Zhaoyang LIU Changjun LUAN Zhaokun ZHANG Zhongguo LI Yanzhong JIA Zhiping | 2005 | Chinese Science Bulletin2005，50，18： | 8 |
| 11 | Ultra-broadband on-chip twisted light emitter for optical communications显示文摘On-chip twisted light emitters are essential components of orbital angular momentum(OAM)communication devices1,2.These devices address the growing demand for high-capacity communication systems by providing an additional degree of freedom for wavelength/frequency division multiplexing(WDM/FDM).Although whispering-gallery-mode-enabled OAM emitters have been shown to possess some advantages3–5,such as compactness and phase accuracy,their inherent narrow bandwidths prevent them from being compatible with WDM/FDM techniques.Here,we demonstrate an ultra-broadband multiplexed OAM emitter that utilizes a novel joint path-resonance phase control concept.The emitter has a micron-sized radius and nanometer-sized features.Coaxial OAM beams are emitted across the entire telecommunication band from 1,450 to 1,650 nm.We applied the emitter to an OAM communication with a data rate of 1.2 Tbit/s assisted by 30-channel optical frequency combs(OFCs).The emitter provides a new solution to further increase capacity in the OFC communication scenario. | Zhenwei Xie Ting Lei Fan Li Haodong Qiu Zecen Zhang Hong Wang Changjun Min Luping Du Zhaohui Li Xiaocong Yuan | 2018 | Light(Science & Applications)2018，7，1： | 7 |

| 14 | The CO_2 absorption and desorption performance of the triethylenetetramine + N,N-diethylethanolamine + H_2O system显示文摘Post-combustion CO_2 capture(PCC) process faces significant challenge of high regeneration energy consumption.Biphasic absorbent is a promising alternative candidate which could significantly reduce the regeneration energy consumption because only the CO_2-concentrated phase should be regenerated. In this work, aqueous solutions of triethylenetetramine(TETA) and N,N-diethylethanolamine(DEEA) are found to be efficient biphasic absorbents of CO_2. The effects of the solvent composition, total amine concentration, and temperature on the absorption behavior, as well as the effect of temperature on the desorption behavior of TETA–DEEA–H2 O system were investigated. An aqueous solution of 1 mol·L-1 TETA and 4 mol·L-1 DEEA spontaneously separates into two liquid phases after a certain amount of CO_2 is absorbed and it shows high CO_2 absorption/desorption performance.About 99.4% of the absorbed CO_2 is found in the lower phase, which corresponds to a CO_2 absorption capacity of 3.44 mol·kg-1. The appropriate absorption and desorption temperatures are found to be 30 °C and 90 °C,respectively. The thermal analysis indicates that the heat of absorption of the 1 mol·L-1 TETA and 4 mol·L-1 DEEA solution is-84.38 kJ·(mol CO_2)-1 which is 6.92 kJ·(mol CO_2)-1 less than that of aqueous MEA. The reaction heat, sensible heat, and the vaporization heat of the TETA–DEEA–H2 O system are lower than that of the aqueous MEA, while its CO_2 capacity is higher. Thus the TETA–DEEA–H2 O system is potentially a better absorbent for the post-combustion CO_2 capture process. | Yaoyao Li Changjun Liu Richard Parnas Yingying Liu Bin Liang Houfang Lu | 2018 | Chinese Journal of Chemical Engineering2018，26，11： | 6 |
| 15 | LRP6 in mesenchymal stem cells is required for bone formation during bone growth and bone remodeling显示文摘Lipoprotein receptor-related protein 6(LRP6) plays a critical role in skeletal development and homeostasis in adults. However, the role of LRP6 in mesenchymal stem cells(MSCs), skeletal stem cells that give rise to osteoblastic lineage, is unknown. In this study, we generated mice lacking LRP6 expression specifically in nestin1MSCs by crossing nestin-Cre mice with LRP6floxmice and investigated the functional changes of bone marrow MSCs and skeletal alterations. Mice with LRP6 deletion in nestin1cells demonstrated reductions in body weight and body length at 1 and 3 months of age. Bone architecture measured by microCT(mCT) showed a significant reduction in bone mass in both trabecular and cortical bone of homozygous and heterozygous LRP6mutant mice. A dramatic reduction in the numbers of osteoblasts but much less significant reduction in the numbers of osteoclasts was observed in the mutant mice. Osterix1osteoprogenitors and osteocalcin1osteoblasts significantly reduced at the secondary spongiosa area, but only moderately decreased at the primary spongiosa area in mutant mice. Bone marrow MSCs from the mutant mice showed decreased colony forming, cell viability and cell proliferation. Thus, LRP6 in bone marrow MSCs is essential for their survival and proliferation, and therefore, is a key positive regulator for bone formation during skeletal growth and remodeling. | Changjun Li Bart O Williams Xu Cao Mei Wan | 2014 | Bone Research2014，2，1： | 6 |
| 16 | Characterization and potential diagnostic application of monoclonal antibodies specific to rabies virus显示文摘Objective:Rabies is invariably a fatal encephalomyelitis that is considered to be a serious public health problem.It is necessary to develop standard rabies virus diagnostic tools,especially for diagnosing the strains prevalent in China.Methods:Monoclonal antibodies(MAbs)specific to rabies virus were produced and characterized by enzyme linked immunosorbent assay(ELISA),isotyping,affinity assay,immunofluorescence assay(IFA),and immunocytochemistry.The MAb,whose affinity was higher for antigen,was used to establish an antigen captureELISA(AC-ELISA)detection system and test the efficiency by using clinical samples.Results:The heavy chain subclasses of two MAbs were all determined to be IgG2a.The 3C7 MAb showed stronger reactivity with rabies virus protein than the 2C5 MAb in an ELISA analysis,whereas the 3C7 MAb showed the highest affinity for antigen.IFA and immunocytochemistry results also indicated that the two MAbs could recognize rabies virus protein in its native form in cell samples.Data obtained using clinical samples showed that rabies virus could be detected by AC-ELISA detection system using the 3C7 MAb.Conclusion:It was potentially useful for the further development of highly sensitive,easily handled,and relatively rapid detection kits/tools for rabies surveillance in those areas where rabies is endemic,especially in China. | Xinjian Liu Xiaomin Feng Qi Tang Zhongcan Wang Zhenning Qiu Yuhua Li Changjun Wang Zhenqing Feng Jin Zhu Xiaohong Guan | 2010 | The Journal of Biomedical Research2010，24，5： | 5 |

| 18 | Retrieve Sea Surface Salinity Using Principal Component Regression Model Based on SMOS Satellite Data显示文摘The sea surface salinity(SSS) is a key parameter in monitoring ocean states. Observing SSS can promote the understanding of global water cycle. This paper provides a new approach for retrieving sea surface salinity from Soil Moisture and Ocean Salinity(SMOS) satellite data. Based on the principal component regression(PCR) model, SSS can also be retrieved from the brightness temperature data of SMOS L2 measurements and Auxiliary data. 26 pair matchup data is used in model validation for the South China Sea(in the area of 4?–25?N, 105?–125?E). The RMSE value of PCR model retrieved SSS reaches 0.37 psu(practical salinity units) and the RMSE of SMOS SSS1 is 1.65 psu when compared with in-situ SSS. The corresponding Argo daily salinity data during April to June 2013 is also used in our validation with RMSE value 0.46 psu compared to 1.82 psu for daily averaged SMOS L2 products. This indicates that the PCR model is valid and may provide us with a good approach for retrieving SSS from SMOS satellite data. | ZHAO Hong LI Changjun LI Hongping LV Kebo ZHAO Qinghui | 2016 | Journal of Ocean University of China2016，15，3： | 5 |
| 19 | Endothelial PDGF-BB/PDGFR-βsignaling promotes osteoarthritis by enhancing angiogenesis-dependent abnormal subchondral bone formation显示文摘The mechanisms that coordinate the shift from joint homeostasis to osteoarthritis(OA)remain unknown.No pharmacological intervention can currently prevent the progression of osteoarthritis.Accumulating evidence has shown that subchondral bone deterioration is a primary trigger for overlying cartilage degeneration.We previously found that H-type vessels modulate aberrant subchondral bone formation during the pathogenesis of OA.However,the mechanism responsible for the elevation of H-type vessels in OA is still unclear.Here,we found that PDGFR-βexpression,predominantly in the CD31^(hi)Emcn^(hi) endothelium,was substantially elevated in subchondral bones from OA patients and rodent OA models.A mouse model of OA with deletion of PDGFR-βin endothelial cells(ECs)exhibited fewer H-type vessels,ameliorated subchondral bone deterioration and alleviated overlying cartilage degeneration.Endothelial PDGFR-βpromotes angiogenesis through the formation of the PDGFR-β/talin1/FAK complex.Notably,endothelium-specific inhibition of PDGFR-βby local injection of AAV9 in subchondral bone effectively attenuated the pathogenesis of OA compared with that of the vehicle-treated controls.Based on the results from this study,targeting PDGFR-βis a novel and promising approach for the prevention or early treatment of OA. | Zhuang Cui Hangtian Wu Ye Xiao Ting Xu Junjie Jia Hancheng Lin Rongmin Lin Kun Chen Yihuang Lin Kaiqun Li Xiaohu Wu Changjun Li Bin Yu | 2022 | Bone Research2022，10，4： | 4 |
| 20 | Automatic tuning of sparse matrix-vector multiplication on multicore clusters显示文摘To have good performance and scalability, parallel applications should be sophisticatedly optimized to exploit intra-node parallelism and reduce inter-node communication on multicore clusters. This paper investigates the automatic tuning of the sparse matrix-vector(Sp MV) multiplication kernel implemented in a partitioned global address space language, which supports a hybrid thread- and process-based communication layer for multicore systems. One-sided communication is used for inter-node data exchange, while intra-node communication uses a mix of process shared memory and multithreading. We develop performance models to facilitate selecting the best configuration of threads and processes hybridization as well as the best communication pattern for Sp MV. As a result, our tuned Sp MV in the hybrid runtime environment consumes less memory and reduces inter-node communication volume, without damaging the data locality. Experiments are conducted on 12 real sparse matrices. On 16-node Xeon and 8-node Opteron clusters, our tuned Sp MV kernel gets on average 1.4X and 1.5X improvement in performance over the well-optimized process-based message-passing implementation, respectively. | LI ShiGang HU ChangJun ZHANG JunChao ZHANG YunQuan | 2015 | Science China(Information Sciences)2015，58，9： | 3 |
