1颈椎前路减压融合术对颈椎病眩晕患者的缓解效果——多中心前瞻性队列研究显示文摘颈椎病患者除颈部疼痛外常伴有眩晕症状,这种颈源性眩晕并非由前庭病理引起。研究表明,退行性椎间盘突出症与颈椎病患者的退行性眩晕有关,而颈椎前路椎间盘切除融合手术可缓解这一症状。本项多中心队列研究的目的在于分析颈椎前路减压(anterior cervical decompression,ACD)手术对颈源性眩晕的缓解效果,同时探讨其发病机制。Peng B Yang L Yang C 李洪吉 王建华 2018中国骨科临床与基础研究杂志2018,10,4:15
2miR-182参与调节胶质母细胞瘤的凋亡、生长和分化(英文)显示文摘Glioblastoma multiforme(GBM)is a lethal,therapy-resistant brain cancer consisting of numerous tumor cell subpopulations,including stem-like glioma-initiating cells(GICs),which contribute to tumor recurrence following initial response to therapy.Here,we identified miR-182 as a regulator of apoptosis,growth,and differentiation programs whose expression level is correlated with GBM patient survival.Repression of Bcl2-like12(Bcl2L12),c-Met,and hypoxia-inducible factor 2α(HIF2A)is of central importance to miR-182 anti-tumor activity,as it results in enhanced therapy susceptibility,decreased GIC sphere size,expansion,and stemness in vitro.To evaluate the tumor-suppressive function of miR-182 in vivo,we synthesized miR-182-based spherical nucleic acids(182-SNAs);i.e.,gold nanoparticles covalently functionalized with mature miR-182 duplexes.Intravenously administered 182-SNAs penetrated the bloodbrain/blood-tumor barriers(BBB/BTB)in orthotopic GBM xenografts and selectively disseminated throughout extravascular glioma parenchyma,causing reduced tumor burden and increased animal survival.Our results indicate that harnessing the anti-tumor activities of miR-182 via safe and robust delivery of 182-SNAs represents a novel strategy for therapeutic intervention in GBM.Kouri FM Hurley LA Daniel WL Day ES Hua Y Hao L Peng CY Merkel TJ Queisser MA Ritner C Zhang H James CD Sznajder JI Chin L Giljohann DA Kessler JA Peter ME Mirkin CA Stegh AH 2015中华神经外科疾病研究杂志2015,14,2:14
3Mapping landslide susceptibility at the Three Gorges Reservoir, China, using gradient boosting decision tree,random forest and information value models显示文摘This work was to generate landslide susceptibility maps for the Three Gorges Reservoir(TGR) area, China by using different machine learning models. Three advanced machine learning methods, namely, gradient boosting decision tree(GBDT), random forest(RF) and information value(InV) models, were used, and the performances were assessed and compared. In total, 202 landslides were mapped by using a series of field surveys, aerial photographs, and reviews of historical and bibliographical data. Nine causative factors were then considered in landslide susceptibility map generation by using the GBDT, RF and InV models. All of the maps of the causative factors were resampled to a resolution of 28.5 m. Of the 486289 pixels in the area,28526 pixels were landslide pixels, and 457763 pixels were non-landslide pixels. Finally, landslide susceptibility maps were generated by using the three machine learning models, and their performances were assessed through receiver operating characteristic(ROC) curves, the sensitivity, specificity,overall accuracy(OA), and kappa coefficient(KAPPA). The results showed that the GBDT, RF and In V models in overall produced reasonable accurate landslide susceptibility maps. Among these three methods, the GBDT method outperforms the other two machine learning methods, which can provide strong technical support for producing landslide susceptibility maps in TGR.CHEN Tao ZHU Li NIU Rui-qing TRINDER C John PENG Ling LEI Tao 2020Journal of Mountain Science2020,17,3:7

6Distinct regulatory mechanism of immunoglobulin gene transcription in epithelial cancer cells显示文摘The restriction of immunoglobulin(Ig)expression to B lymphocytes is well established.However,several reports have confirmed that the Ig gene can be expressed in many non-B cancer cells and/or some normal cells.Our aim is to determine whether the Ig gene promoter can be activated in non-B cancer cells and to identify the regulatory mechanism for Ig gene expression.Our results show that the Ig promoter of VH4-59 was activated in several non-B cancer cell lines.Moreover,two novel positive regulatory elements,an enhancer-like element at 2800 to 2610 bp and a copromoter-like element at 2610 to 2300 bp,were identified in two epithelial cancer cell lines,HeLa S3 and HT-29.The octamer element(59-ATGCAAAT-39)located in the Ig promoter,a crucial element for B-cell-derived Ig gene transcription,was also very important for non-B-cell-derived Ig gene transcription.More importantly,we confirmed that octamer-related protein-1(Oct-1),but not Oct-2,was a crucial transcriptional factor for Ig gene transcription due to its ability to bind to the octamer element of the Ig promoter in epithelial cancer cells.These results suggested the presence of a distinct regulatory mechanism for Ig gene expression in non-B cancer cells.Xiaohui Zhu Lina Wu Li Zhang Peng Hao Shuai Zhang Jing Huang Jie Zheng Yinan Liu Wenjun Li Yingmei Zhang Chunyan Zhou Youhui Zhang C Cameron Yin Xiaoyan Qiu 2010Cellular & Molecular Immunology2010,7,4:5

8Energy Efficient Run-Time Incremental Mapping for 3-D Networks-on-Chip显示文摘3-D Networks-on-Chip(NoC) emerge as a potent solution to address both the interconnection and design complexity problems facing future Multiprocessor System-on-Chips(MPSoCs).Effective run-time mapping on such 3-D NoC-based MPSoCs can be quite challenging,as the arrival order and task graphs of the target applications are typically not known a priori,which can be further complicated by stringent energy requirements for NoC systems.This paper thus presents an energy-aware run-time incremental mapping algorithm(ERIM) for 3-D NoC which can minimize the energy consumption due to the data communications among processor cores,while reducing the fragmentation effect on the incoming applications to be mapped,and simultaneously satisfying the thermal constraints imposed on each incoming application.Specifically,incoming applications are mapped to cuboid tile regions for lower energy consumption of communication and the minimal routing.Fragment tiles due to system fragmentation can be gleaned for better resource utilization.Extensive experiments have been conducted to evaluate the performance of the proposed algorithm ERIM,and the results are compared against the optimal mapping algorithm(branch-and-bound) and two heuristic algorithms(TB and TL).The experiments show that ERIM outperforms TB and TL methods with significant energy saving(more than 10%),much reduced average response time,and improved system utilization.Xiao-Hang Wang Peng Liu Mei Yang Maurizio Palesi Ying-Tao Jiang Michael C Huang 2013Journal of Computer Science & Technology2013,28,1:5

10Effect of Temperature and Strain Rate on Dynamic Properties of Low Silicon TRIP Steel显示文摘The dynamic tensile test of 0·11C-0·62Si-1·65 Mn TRIP steel was carried out at different strain ratesand test temperatures . The results showthat both temperature and strain rate affect the retained austenite trans-formation . At high strain rates ,the uniformelongation decreases , whereas the total elongation and energy absorp-tionincrease . The tensile strengthis less strain rate sensitive . With raising test temperature ,the tensile strengthis reduced and the mechanical properties generally deteriorate ,especially at 110 ℃. However ,excellent mechani-cal properties were obtained at 50 ℃and 75 ℃.TIAN Rong LI Lin B C De Cooman WEI Xi-chen SUN Peng 2006Journal of Iron and Steel Research(International)2006,13,3:5
