| 1 | CT image fusion in the evaluation of radiation treatment planning for non-small cell lung cancer显示文摘Objective: We studied the application of CT image fusion in the evaluation of radiation treatment planning for non-small cell lung cancer (NSCLC). Methods: Eleven patients with NSCLC, who were treated with three-dimensional con-formal radiation therapy, were studied. Each patient underwent twice sequential planning CT scan, i.e., at pre-treatment, and at mid-treatment for field reduction planning. Three treatment plans were established in each patient: treatment plan A was based on the pre-treatment planning CT scans for the first course of treatment, plan B on the mid-treatment planning CT scans for the second course of treatment, and treatment plan F on the fused images for the whole treatment. The irradiation doses received by organs at risk in the whole treatment with treatment A and B plans were estimated by the plus of the parameters in treatment plan A and B, assuming that the parameters involve the different tissues (i.e. V20=AV20+BV20), or the same tissues within an organ (i.e. Dmax=ADmax+BDmax). The assessment parameters in the treatment plan F were calculated on the basis of the DVH of the whole treatment. Then the above assessment results were compared. Results: There were marked differ-ences between the assessment results derived from the plus of assessment parameters in treatment plan A and B, and the ones derived from treatment plan F. Conclusion: When a treatment plan is altered during the course of radiation treatment, image fusion technique should be performed in the establishment of a new one. The estimation of the assessment parameters for the whole treatment with treatment plan A and B by simple plus, is inaccurate. | WeiGe Guangjin Yuan Changhu Li Yaogui Wu Yanyan Zhang Ximing Xu | 2008 | The Chinese-German Journal of Clinical Oncology2008，7，6： | 10 |
| 2 | Characteristics and dynamics analysis of Populus euphratica populations in the middle reaches of Tarim River显示文摘Populus euphratica Oliv. is widely distributed along the Tarim River. Maintaining stability of P. euphratica population is important to local development. This study explored the static life table, survivorship curves and four function curves (survival rate, cumulative mortality rate, mortality density, and hazard rate), and development index of P. euphratica population in the middle reaches of Tarim River. The results indicated that the age structure of P. euphratica population belonged to positive pyramidal type, which meant young age-class individuals occupied most populations. The number ofⅠ-Ⅱage classes accounted for 66.2% of whole population, and this indicated that there were abundant subsequent seedlings resources to support the growth of P. euphratica population in the middle reaches of Tarim River. The survivorship curve of P. euphratica belonged to the Deevey Ⅲ (concave-type) and the development index was 47.72%. Four function curves revealed that the individuals of P. euphratica sharply decreased at the initial stage and then leveled off at the late stage of survival curve. Time sequence prediction models predicted that the number of midlife individuals would increase in future 10, 20, 30 years, and P. euphratica population grew steadily as a result of rich saplings. | Wu, JunXia Zhang, XiMing Deng, ChaoZhou Liu, GuoJun Li, Hong | 2010 | Journal of Arid Land2010，2，4： | 9 |
| 3 | Paleomagnetic results from Late Carboniferous to Early Permian rocks in the northern Qiangtang terrane, Tibet, China, and their tectonic implications显示文摘Results of a systematic paleomagnetic study are reported based on Late Carboniferous to Early Permian sedimentary rocks on the north slope of the Tanggula Mountains,in the northern Qiangtang terrane(NQT),Tibet,China.Data revealed that magnetic minerals in limestone samples from the Zarigen Formation(CP^z)are primarily composed of magnetite,while those in sandstone samples from the Nuoribagaribao Formation(Pnr)are dominated by hematite alone,or hematite and magnetite in combination.Progressive thermal,or alternating field,demagnetization allowed us to isolate a stable high temperature component(HTC)in 127 specimens from 16 sites which successfully passed the conglomerate test,consistent with primary remnance.The tilt-corrected mean direction for Late Carboniferous to Early Permian rocks in the northern Qiangtang terrane is D_s=30.2°,I_s=-40.9°,k_s=269.0,a_(95)=2.3°,N=16,which yields a corresponding paleomagnetic pole at 25.7°N,241.5°E(dp/dm=2.8°/1.7°),and a paleolatitude of 23.4°S.Our results,together with previously reported paleomagnetic data,indicate that:(1)the NQT in Tibet,China,was located at a low latitude in the southern hemisphere,and may have belonged to the northern margin of Gondwana during the Late Carboniferous to Early Permian;(2)the Paleo-Tethys Ocean was large during the Late Carboniferous to Early Permian,and(3)the NQT subsequently moved rapidly northwards,perhaps related to the fact that the Paleo-Tethys Ocean was rapidly contracting from the Late Permian to Late Triassic while the Bangong Lake-Nujiang Ocean,the northern branch of the Neo-Tethys Ocean,expanded rapidly during this time. | YANG XingFeng CHENG Xin ZHOU YaNan MA Lun ZHANG XiaoDong YAN ZhaoSheng PENG XiMing SU HaiLun WU HanNing | 2017 | Science China Earth Sciences2017，60，1： | 5 |
| 4 | Low-overpotential electrochemical ammonia synthesis using BiOCl-modified 2D titanium carbide MXene显示文摘Electrochemical synthesis of ammonia has the advantages of low energy consumption and promising environmental protection,as compared to the traditional Haber-Bosch process.However,the commercial utilization of this novel system is limited by the low Faradaic efficiency,poor ammonia yield and high overpotential due to the strong NN bond and the dominant competing reaction of hydrogen evolution reaction(HER).Herein,a BiOCl-modified two-dimensional(2D)titanium carbide MXenes nanocomposite(BiOCl@Ti_(3)C_(2)T_(x))is proposed as a promising electrocatalyst for ambient nitrogen(N_(2))reduction reaction with excellent catalytic performance and superior long-term stability at low overpotential.In 0.1 mol/L HCl,this catalyst attains a high Faradic efficiency of 11.98%and a NH_(3)yield of 4.06μg h^(-1)cm^(-2)at-0.10 V(vs.RHE),benefiting from its strong interaction of Bi 6p band with the N 2p orbitals,combined with its large specific surface area and the facile electron transfer. | Yu Wang Munkhbayar Batmunkh Hui Mao Hui Li Baohua Jia Shuyao Wu Daliang Liu Ximing Song Ying Sun Tianyi Ma | 2022 | Chinese Chemical Letters2022，33，1： | 2 |

| 6 | Trans-cinnamaldehyde promotes nitric oxide release via the protein kinase-B/v-Akt murine thymoma viral oncogene-endothelial nitric oxide synthase pathway to alleviate hypertension in SHR.Cg-Lepr^(cp)/NDmcr rats显示文摘OBJECTIVE:To evaluate whether endothelial dysfunction and hypertension are prevented by trans-cinnamaldehyde(t CA) through the activation of endothelial nitric oxide synthase(e NOS).METHODS:Human umbilical vein endothelial cells(HUVECs) were cultured in vitro and stimulated with t CA to determine cell viability using the methyl thiazolyl tetrazolium assay.The effect of t CA on nitric oxide(NO) production was determined by diaminofluorescein-dyes in the absence or presence of inhibitors of e NOS,AMPK,PKA,and AKT.The effect of t CA on blood pressure was determined by the tail-cuff method in obesity spontaneous hypertension(SHR.Cg-Leprcp/NDmcr) rats.The phosphorylation of e NOS and protein expression of the insulin-signaling pathway(Ins R-IRS1-PI3 K-AKT)were measured by western blot.RESULTS:t CA at concentrations less than 100 μM did not affect cell viability in cultured HUVECs.Stimulation with t CA promoted NO release in a time-dependent manner compared with the control group.t CA-treated HUVECs also significantly increased AKT-Ser473 and e NOS-Ser1177 phosphorylation.In SHR-CP rats,treatment with t CA at a dose of 40 mg/kg/day for 6 weeks markedly reduced the systolic blood pressure and diastolic blood pressure,increased the phosphorylation of AKT and e NOS,and increased urinary nitric oxidation.CONCLUSION:t CA attenuated endothelial dysfunction and reduced blood pressure in SHR-CP rats.The underlying mechanisms may involve the increase in AKT and e NOS phosphorylation and the release of e NOS-derived NO. | Zhang Lu Wu Lili Liu Ximing Yoshitomi Hisae Ikeda Katsumi Negishi Hiroko Pan Yajing Sun Wen Qin Lingling Li Juan-E Xu Tunhai Liu Tonghua Gao Ming | 2018 | Journal of Traditional Chinese Medicine2018，38，4： | 2 |

| 11 | Divergent responses of soil carbon and nitrogen pools to short-term nitrogen addition between two plantations in Northeast China显示文摘Nitrogen(N)deposition has a profound influence on forest soil carbon(C)and N pools,but there was no consensus on the responses of different C and N components in different forest types.In this study,a two-year simulated N deposition experiment with four levels of N(NH4NO3)-addition treatments(0,50,100,and 150 kg N/hm^(2)·a)were conducted in Larix gmelinii(LG)and Quercus mongolica(QM)plantation in Northeast China,in order to investigate the C and N pool dynamics under continuously enhanced N deposition.Soil organic carbon(SOC),soil total N(STN)and their active components(readily oxidizable C,ROC;dissolved organic C,DOC;microbial biomass C,MBC,dissolved organic N,DON;microbial biomass N,MBN)of the forest soil were measured monthly from May to October 2017.C and N contents in LG were observed higher than in QM.N addition had no effect on SOC and STN of LG,but significantly increased SOC and STN of QM at low N addition level.Low N addition generally raised active C components(ROC,DOC,and MBC)in both plantations,whereas high N addition did not significantly affect these components,or even decreased ROC in LG soil.Low N addition also increased STN and MBN of QM,while no significant change in STN and MBN of LG was observed.DON was directly affected by N addition and increased significantly with elevated N addition levels.The results indicated that N addition,especially of low rate,might enhance the C sequestration capacity of the forest soils and mitigate climate change. | Yedong Li Bo Wang Sen Dou Haoyue Shen Liyong Mei Yang Zhang Ximing Zeng Yaya Zhang Yameng Pei Haoye Ren Shimin Wu | 2019 | International Journal of Agricultural and Biological Engineering2019，12，6： | 1 |
| 12 | Regulation of the inward K^+-channels in stomatal guard cells by cytoskeletal microtubules显示文摘Patch clamp techniques were applied to investigating the regulation of the inward K^+channels in Vicia stomatal guard cells by cytoskeletal microtubules. The intracellular addition of either microtubule-disassembling reagent amprophos-methyl (APM) or microtubule-stabilizing reagent taxol resulted in significant inhibition of the inward K^+ -currents across the plasma membranes of Vicia stomatal guard cells. The results suggest that the activation of the inward K^+channels in stomatal guard cells requires proper dynamic organization of cytoskeletal microtubules. The regulation of the inward K^+-channels in guard cells by microtubules may mediate the regulation of stomatal movements by cytoskeleton. | Ximing Zhou Weihua Wu Ming Yuan Xuechen Wang | 1999 | Chinese Science Bulletin1999，44，10： | 1 |

| 18 | DESIGN AND IMPLEMENTATION OF SINGLE-BUFFERED ROUTERS显示文摘A Single-Buffered (SB) router is a router where only one stage of shared buffering is sand- wiched between two interconnects in comparison of a Combined Input and Output Queued (CIOQ) router where a central switch fabric is sandwiched between two stages of buffering. The notion of SB routers was firstly proposed by the High-Performance Networking Group (HPNG) of Stanford Uni- versity, along with two promising designs of SB routers: one of which was Parallel Shared Memory (PSM) router and the other was Distributed Shared Memory (DSM) router. Admittedly, the work of HPNG deserved full credit, but all results presented by them appeared to relay on a Centralized Memory Management Algorithm (CMMA) which was essentially impractical because of the high processing and communication complexity. This paper attempts to make a scalable high-speed SB router completely practical by introducing a fully distributed architecture for managing the shared memory of SB routers. The resulting SB router is called as a Virtual Output and Input Queued (VOIQ) router. Furthermore, the scheme of VOIQ routers can not only eliminate the need for the CMMA scheduler, thus allowing a fully distributed implementation with low processing and commu- nication complexity, but also provide QoS guarantees and efficiently support variable-length packets in this paper. In particular, the results of performance testing and the hardware implementation of our VOIQ-based router (NDSC? SR1880-T? series) are illustrated at the end of this paper. The pro- posal of this paper is the first distributed scheme of how to design and implement SB routers publi- cized till now. | Hu Ximing Qu Jing Wang Binqiang Wu Jiangxing | 2007 | Journal of Electronics(China)2007，24，4： | 0 |

| 20 | Inorganic imaging nanoprobes for breast cancer diagnosis显示文摘Breast cancer is one of the most prevalent cancers worldwide,and early diagnosis and screening are vital to its successful treatment.Although medical imaging methods can assist in the early detection of breast cancer,imaging methods that are currently used for clinical diagnosis have drawbacks,such as low sensitivity and accuracy.Contrast agents are often used in diagnostic imaging to address these drawbacks.Nanocontrast agents have attracted considerable attention in recent years due to their unique physicochemical characteristics.Among these agents,inorganic nanoprobes have been substantially developed through improvements in synthesis techniques and pairings with other organic molecules.This paper mainly summarizes the specific applications of inorganic nanoprobes in the magnetic resonance imaging,fluorescence imaging,radionuclide imaging,and bimodal/multimodal imaging of breast cancer. | Qi Guo Maosen Hong Tong Wu Lei Chen Guangxin Duan Jianfeng Zeng Ximing Wang Ling Wen Chunhong Hu | 2023 | Radiation Medicine and Protection2023，4，2： | 0 |
