| 1 | Single whispering-gallery mode lasing in polymer bottle microresonators via spatial pump engineering显示文摘Single-mode lasing in whispering-gallery mode(WGM)microresonators is challenging to achieve.In bottle microresonators,the highly non-degenerated WGMs are spatially well-separated along the long-axis direction and provide mode-selection capability.In this work,by engineering the pump intensity to modify the spatial gain profiles of bottle microresonators,we demonstrate a simple and general approach to realizing single-mode WGM lasing in polymer bottle microresonators.The pump intensity is engineered into an interference distribution on the bottle microresonator surface.By tuning the spacing between axial positions of the interference pump patterns,the mode intensity profiles of single-bottle WGMs can be spatially overlapped with the interference stripes,intrinsically enabling single-mode lasing and selection.Attractive advantages of the system,including high sidemode suppression factors 420 dB,large spectral tunability 48 nm,low-lasing threshold and reversible control,are presented.Our demonstrated approach may have a variety of promising applications,ranging from tunable single-mode lasing and sensing to nonlinear optics. | Fuxing Gu Fuming Xie Xing Lin Shuangyi Linghu Wei Fang Heping Zeng Limin Tong Songlin Zhuang | 2017 | Light(Science & Applications)2017，6，1： | 17 |
| 2 | Research and Practice of Blending Teaching Based on “MOOC + SPOC + Flipped Classroom” for Software Engineering显示文摘Based on 'MOOC + SPOC + Flipped Classroom', a particular blending teaching pattern adapting to MOOC teaching is proposed to strengthen software engineering students' abilities to study themselves and practice innovatively. Firstly, the process of MOOC development in China is introduced. The distinguishing feature and effect of MOOC teaching are analyzed, followed by the comparison with traditional class. The online Plus offline blending teaching pattern is the combination of online self-study on MOOC before class, seminar study of flipped classroom in class and the summary after class. With the demonstration of a typical case, a progressive strategy is given to implement blending teaching. Finally, the blending teaching pattern is assessed from multiple perspectives, of which both advantages and disadvantages are dissected. Through primary exploration, introducing online study and flipped classroom, blending teaching plays a positive role in software engineering teaching, which means traditional teaching pattern is changed. Meanwhile, students' innovative consciousness and practical ability are inspired. Nevertheless, new problems arise, so that intensive practice and improvement are necessary. | Ce Zhang Dianhui Chu Songlin Gu Xiaofei Xu Jianan Jiang Zheng Wang Hua Zhang | 2018 | 计算机教育2018，，12： | 14 |
| 3 | Non-coding RNAs as Emerging Regulators of Neural Injury Responses and Regeneration显示文摘Non-coding RNAs(ncRNAs) are a large cluster of RNAs that do not encode proteins,but have multiple functions in diverse cellular processes.Mounting evidence indicates the involvement of nc RNAs in the physiology and pathophysiology of the central and peripheral nervous systems.It has been shown that numerous ncRNAs,especially micro RNAs and long non-coding RNAs,are differentially expressed after insults such as acquired brain injury,spinal cord injury,and peripheral nerve injury.These ncRNAs affect neuronal survival,neurite regrowth,and glial phenotype primarily by targeting specific mRNAs,resulting in translation repression or degradation of the mRNAs.An increasing number of studies have investigated the regulatory roles of micro RNAs and long non-coding RNAs in neural injury and regeneration,and thus a new research field is emerging.In this review,we highlight current progress in the field in an attempt to provide further insight into post-transcriptional changes occurring after neural injury,and to facilitate the potential use of ncRNAs for improving neural regeneration.We also suggest potential directions for future studies. | Songlin Zhou Fei Ding Xiaosong Gu | 2016 | Neuroscience Bulletin2016，32，3： | 12 |

| 5 | Single-mode lasing via loss engineering in fiber-taper-coupled polymer bottle microresonators显示文摘Due to the lack of mode selection capability, single whispering-gallery-mode(WGM) lasing is a challenge to achieve. In bottle microresonators, the highly nondegenerated WGMs are spatially well-separated along the long-axis direction and provide mode selection according to their axial mode numbers. In this work, we use a loss-engineering approach to suppress the higher-order WGMs and demonstrate single-mode lasing emission in small polymer bottle microresonators. The fiber tapers are not only used to couple pump light into the bottle microresonators to excite the WGMs but also to bring optical losses that are induced from the diameter mismatch between fiber tapers and microresonators. By adjusting the coupling positions, the diameters of fiber tapers, and the coupling angles, single fundamental-mode lasing is efficiently generated with side-mode suppression factors over 15 dB. Our loss-engineering approach is convenient just by moving the fiber taper and may findpromising applications in miniature tunable single-mode lasers and sensors. | FUMING XIE NI YAO WEI FANG HAIFENG WANG FUXING GU SONGLIN ZHUANG | 2017 | Photonics Research2017，5，6： | 4 |

| 9 | Deciphering glial scar after spinal cord injury显示文摘Spinal cord injury(SCI)often leads to permanent disability,which is mainly caused by the loss of functional recovery.In this review,we aimed to investigate why the healing process is interrupted.One of the reasons for this interruption is the formation of a glial scar around the severely damaged tissue,which is usually covered by reactive glia,macrophages and fibroblasts.Aiming to clarify this issue,we summarize the latest research findings pertaining to scar formation,tissue repair,and the divergent roles of blood-derived monocytes/macrophages,ependymal cells,fibroblasts,microglia,oligodendrocyte progenitor cells(OPCs),neuron-glial antigen 2(NG2)and astrocytes during the process of scar formation,and further analyse the contribution of these cells to scar formation.In addition,we recapitulate the development of therapeutic treatments targeting glial scar components.Altogether,we aim to present a comprehensive decoding of the glial scar and explore potential therapeutic strategies for improving functional recovery after SCI. | Yu Zhang Shuhai Yang Chang Liu Xiaoxiao Han Xiaosong Gu Songlin Zhou | 2021 | Burns & Trauma2021，9，1： | 1 |
| 10 | Design and applicability analysis of independent double acquisition circuit of all-fiber optical current transformer显示文摘The advantages of the all-fiber optical current transformer include but are not limited to being small in size,having no magnetic saturation,exhibiting high measurement accuracy,and boasting strong electromagnetic interference resistance.However,the high cost of the all-fiber optical transformer limits its promotion and application in engineering.This paper proposes a design scheme of an independent double acquisition loop for the all-fiber optical current transformer based on the single optical path.Firstly,based on the closed-loop control mode and open-loop control mode,the twochannel sampling signal demand for relay protection,and the independent dual-acquisition loop design scheme of the all-fiber optical current transformer are proposed.Secondly,the reliability and economic feasibility of the scheme are demonstrated by an analysis of system failure and cost.The results show that the scheme can actualize the acquisition function of two independent all-fiber optical current transformer products on a single all-fiber current transformer in an integrated manner,which greatly reduces the cost of the all-fiber optical current transformer in engineering applications. | Songlin Gu Liu Han Dongwei Liu Wenbin Yu Zhihong Xiao Teng Feng | 2019 | Global Energy Interconnection2019，2，6： | 1 |
| 11 | KIAA1199 induces advanced biological behavior and development of ovarian cancer through activation of the IL-6/STAT3 pathway显示文摘Recently,abnormal expression of KIAA1199 has been detected in Epithelial Ovarian Cancer(EOC).However,the underlined anti-ovarian cancer mechanism of KIAA1199 remains to be enlightened.In our study,we performed to elucidate the effects of KIAA1199 on the advanced biological behavior of EOC cells through activation of the IL-6/STAT3 pathway.Confirmed by immunohistochemistry,KIAA1199 was highly expressed in ovarian borderline and malignant epithelial tumors.A retrospective analysis found that EOC patients with low expression of KIAA1199 had a significantly higher 5-year survival rate than those with high expression.Mechanistically,IL-6 was used to stimulate EOC cells,and the expression of KIAA1199,STAT3 and p-STAT3 increased after IL-6 stimulation.These results could show that KIAA1199 is transcriptionally activated by IL6/STAT3 pathway,thereby accelerating the deterioration of EOC.KIAA1199 could also be used as a poor prognosis factor and potential target in treatment. | SHUTING GU JINGYI QIN SAINAN GAO ZHEN WANG QI MENG YAN LI BING LU SONGLIN ZHOU YUNZHAO XU | 2022 | BIOCELL2022，46，3： | 0 |
| 12 | RNA sequencing of exosomes secreted by fibroblast and Schwann cells elucidates mechanisms underlying peripheral nerve regeneration显示文摘Exosomes exhibit complex biological functions and mediate a variety of biological processes,such as promoting axonal regeneration and functional recove ry after injury.Long non-coding RNAs(IncRNAs)have been reported to play a crucial role in axonal regeneration.Howeve r,the role of the IncRNA-microRNAmessenger RNA(mRNA)-competitive endogenous RNA(ceRNA)network in exosome-mediated axonal regeneration remains unclear.In this study,we performed RNA transcriptome sequencing analysis to assess mRNA expression patterns in exosomes produced by cultured fibroblasts(FC-EXOs)and Schwann cells(SCEXOs).Diffe rential gene expression analysis,Gene Ontology analysis,Kyoto Encyclopedia of Genes and Genomes analysis,and protein-protein intera ction network analysis were used to explo re the functions and related pathways of RNAs isolated from FC-EXOs and SC-EXOs.We found that the ribosome-related central gene Rps5 was enriched in FC-EXOs and SC-EXOs,which suggests that it may promote axonal regeneration.In addition,using the miRWalk and Starbase prediction databases,we constructed a regulatory network of ceRNAs targeting Rps5,including 27 microRNAs and five IncRNAs.The ceRNA regulatory network,which included Ftx and Miat,revealed that exsosome-derived Rps5 inhibits scar formation and promotes axonal regeneration and functional recovery after nerve injury.Our findings suggest that exosomes derived from fibro blast and Schwann cells could be used to treat injuries of peripheral nervous system. | Xinyang Zhou Yehua Lv Huimin Xie Yan Li Chang Liu Mengru Zheng Ronghua Wu Songlin Zhou Xiaosong Gu Jingjing Li Daguo Mi | 2024 | Neural Regeneration Research2024，19，8： | 0 |
| 13 | Spatiotemporal Dynamics of the Molecular Expression Pattern显示文摘Nerve regeneration in adult mammalian spinal cord is poor because of the lack of intrinsic regeneration of neurons and extrinsic factors–the glial scar is triggered by injury and inhibits or promotes regeneration.Recent technological advances in spatial transcriptomics(ST)provide a unique opportunity to decipher most genes systematically throughout scar formation,which remains poorly understood.Here,we frst constructed the tissue-wide gene expression patterns of mouse spinal cords over the course of scar formation using ST after spinal cord injury from 32 samples.Locally,we profled gene expression gradients from the leading edge to the core of the scar areas to further understand the scar microenvironment,such as neurotransmitter disorders,activation of the pro-infammatory response,neurotoxic saturated lipids,angiogenesis,obstructed axon extension,and extracellular structure re-organization.In addition,we described 21 cell transcriptional states during scar formation and delineated the origins,functional diversity,and possible trajectories of subpopulations of fbroblasts,glia,and immune cells.Specifcally,we found some regulators in special cell types,such as Thbs1 and Col1a2 in macrophages,CD36 and Postn in fbroblasts,Plxnb2 and Nxpe3 in microglia,Clu in astrocytes,and CD74 in oligodendrocytes.Furthermore,salvianolic acid B,a blood–brain barrier permeation and CD36 inhibitor,was administered after surgery and found to remedy fbrosis.Subsequently,we described the extent of the scar boundary and profled the bidirectional ligand-receptor interactions at the neighboring cluster boundary,contributing to maintain scar architecture during gliosis and fbrosis,and found that GPR37L1_PSAP,and GPR37_PSAP were the most signifcant gene-pairs among microglia,fbroblasts,and astrocytes.Last,we quantifed the fraction of scar-resident cells and proposed four possible phases of scar formation:macrophage infltration,proliferation and diferentiation of scar-resident cells,scar emergence,and scar stationary.Together,these profles delineated the spatial heterogeneity of the scar,confrmed the previous concepts about scar architecture,provided some new clues for scar formation,and served as a valuable resource for the treatment of central nervous system injury. | Leilei Gong Yun Gu Xiaoxiao Han Chengcheng Luan Chang Liu Xinghui Wang Yufeng Sun Mengru Zheng Mengya Fang Shuhai Yang Lai Xu Hualin Sun Bin Yu Xiaosong Gu Songlin Zhou | 2023 | Neuroscience Bulletin2023，39，2： | 0 |

| 17 | Transcriptome Analysis of Schwann Cells at Various Stages of Myelination Implicates Chromatin Regulator Sin3A in Control of Myelination Identity显示文摘Enhancing remyelination after injury is of utmost importance for optimizing the recovery of nerve function.While the formation of myelin by Schwann cells(SCs)is critical for the function of the peripheral nervous system,the temporal dynamics and regulatory mechanisms that control the progress of the s lineage through myelination require further elucidation.Here,using in vitro co-culture models,gene expression profiling of laser capture-microdissected SCs at various stages of myelination,and multilevel bioinformatic analysis,we demonstrated that SCs exhibit three distinct transcriptional characteristics duringmyelination:the immature,promyelinating,and myelinating states.We showed that suppressor interacting 3a(Sin3A)and 16 other transcription factors and chromatin regulators play important roles in the progress of myelination.Sin3A knockdown in the sciatic nerve or specifically in SCs reduced or delayed the myelination of regenerating axons in a rat crushed sciatic nerve model,while overexpression of Sin3A greatly promoted the remyelination of axons.Further,in vitro experiments revealed that Sin3A silencing inhibited SC migration and differentiation at the promyelination stage and promoted SC proliferation at the immature stage.In addition,SC differentiation and maturation may be regulated by the Sin3A/histone deacetylase2(HDAC2)complex functionally cooperating with Sox10,as demonstrated by rescue assays.Together,these results complement the recent genome and proteome analyses of SCs during peripheral nerve myelin formation.The results also reveal a key role of Sin3A-dependent chromatin organization in promoting myelinogenic programs and SC differentiation to control peripheral myelination and repair.These findings may inform new treatments for enhancing remyelination and nerveregeneration. | Bin Zhang Wenfeng Su Junxia Hu Jinghui Xu Parizat Askar Shuangxi Bao Songlin Zhou Gang Chen Yun Gu | 2022 | Neuroscience Bulletin2022，38，7： | 0 |
