| 1 | Molecular screening of patients with nonsyndromic hearing loss from Nanjing city of China显示文摘Hearing loss is the most frequent sensory disorder involving a multitude of factors,and at least 50% of cases are due to genetic etiology.To further characterize the molecular etiology of hearing loss in the Chinese population,we recruited a total of 135 unrelated patients with nonsyndromic sensorineural hearing loss (NSHL) for mutational screening of GJB2,GJB3,GJB6,SLC26A4,SLC26A5 IVS2-2A>G and mitochondrial 12SrRNA,tRNA Ser(UCN) by PCR amplification and direct DNA sequencing.The carrier frequencies of deafness-causing mutations in these patients were 35.55% in GJB2,3.70% in GJB6,15.56% in SLC26A4 and 8.14% in mitochondrial 12SrRNA,respectively.The results indicate the necessity of genetic screening for mutations of these causative genes in Chinese population with nonsyndromic hearing loss. | Yajie Lu Dachun Dai Zhibin Chen Xin Cao Xingkuan Bu Qinjun Wei Guangqian Xing | 2011 | The Journal of Biomedical Research2011，25，5： | 30 |
| 2 | Substance P-modified human serum albumin nanoparticles loaded with paclitaxel for targeted therapy of glioma显示文摘The blood–brain barrier(BBB) and the poor ability of many drugs to cross that barrier greatly limits the efficacy of chemotherapies for glioblastoma multiforme(GBM). The present study exploits albumin as drug delivery vehicle to promote the chemotherapeutic efficacy of paclitaxel(PTX) by improving the stability and targeting efficiency of PTX/albumin nanoparticles(NPs). Here we characterize PTX-loaded human serum albumin(HSA) NPs stabilized with intramolecular disulfide bonds and modified with substance P(SP) peptide as the targeting ligand. The fabricated SP-HSA-PTX NPs exhibited satisfactory drug-loading content(7.89%) and entrapment efficiency(85.7%) with a spherical structure(about 150 nm) and zeta potential of -12.0 mV. The in vitro drug release from SP-HSA-PTX NPs occurred in a redox-responsive manner. Due to the targeting effect of the SP peptide, cellular uptake of SP-HSA-PTX NPs into brain capillary endothelial cells(BCECs) and U87 cells was greatly improved.The low IC_(50), prolonged survival period and the obvious pro-apoptotic effect shown by TUNEL analysis all demonstrated that the fabricated SP-HSA-PTX NPs showed a satisfactory anti-tumor effect and could serve as a novel strategy for GBM treatment. | Chunhui Ruan Lisha Liu Yifei Lu Yu Zhang Xi He Xinli Chen Yujie Zhang Qinjun Chen Qin Guo Tao Sun Chen Jiang | 2018 | Acta Pharmaceutica Sinica B2018，8，1： | 19 |
| 3 | OSBPL2-disrupted pigs recapitulate dual features of human hearing loss and hypercholesterolaemia显示文摘Oxysterol binding protein like 2(OSBPL2), an important regulator in cellular lipid metabolism and transport, was identified as a novel deafness-causal gene in our previous work. To resemble the phenotypic features of OSBPL2 mutation in animal models and elucidate the potential genotypephenotype associations, the OSBPL2-disrupted Bama miniature(BM) pig model was constructed using CRISPR/Cas9-mediated gene editing, somatic cell nuclear transfer(SCNT) and embryo transplantation approaches, and then subjected to phenotypic characterization of auditory function and serum lipid profiles. The OSBPL2-disrupted pigs displayed progressive hearing loss(HL) with degeneration/apoptosis of cochlea hair cells(HCs) and morphological abnormalities in HC stereocilia, as well as hypercholesterolaemia. High-fat diet(HFD) feeding aggravated the development of HL and led to more severe hypercholesterolaemia. The dual phenotypes of progressive HL and hypercholesterolaemia resembled in OSBPL2-disrupted pigs confirmed the implication of OSBPL2 mutation in nonsydromic hearing loss(NSHL) and contributed to the potential linkage between auditory dysfunction and dyslipidaemia/hypercholesterolaemia. | Jun Yao Huasha Zeng Min Zhang Qinjun Wei Ying Wang Haiyuan Yang Yajie Lu Rongfeng Li Qiang Xiong Lining Zhang Zhibin Chen Guangqian Xing Xin Cao Yifan Dai | 2019 | Journal of Genetics and Genomics2019，46，8： | 7 |
| 4 | Rational design of MoS_(2) nanosheets decorated on mesoporous hollow carbon spheres as a dual-functional accelerator in sulfur cathode for advanced pouch-type Li–S batteries显示文摘Developing sulfur cathodes with high catalytic activity on accelerating the sluggish redox kinetics of lithium polysulfides(Li PSs) and unveiling their mechanisms are pivotal for advanced lithium–sulfur(Li–S)batteries. Herein, MoS2 is verified to reduce the Gibbs free energy for rate-limiting step of sulfur reduction and the dissociation energy of lithium sulfide(Li2 S) for the first time employing theoretical calculations. The Mo S2 nanosheets coated on mesoporous hollow carbon spheres(MHCS) are then reasonably designed as a sulfur host for high-capacity and long-life Li–S battery, in which MHCS can guarantee the high sulfur loading and fast electron/ion transfer. It is revealed that the shuttle effect is efficiently inhibited because of the boosted conversion of Li PSs. As a result, the coin cell based on the MHCS@Mo S2-S cathode exhibits stable cycling performance maintaining 735.7 mAh g^(-1) after 500 cycles at 1.0 C. More importantly, the pouch cell employing the MHCS@Mo S2-S cathodes achieves high specific capacity of1353.2 m Ah g^(-1) and prominent cycle stability that remaining 960.0 m Ah g^(-1) with extraordinary capacity retention of 79.8% at 0.1 C after 170 cycles. Therefore, this work paves a new avenue for developing practical high specific energy and long-life pouch-type Li–S batteries. | Qinjun Shao Pengfei Lu Lei Xu Decai Guo Jing Gao Zhong Shuai Wu jian Chen | 2020 | Journal of Energy Chemistry2020，29，12： | 7 |
| 5 | GLUT1-mediated effective anti-miRNA21 pompon for cancer therapy显示文摘Oncogenic microRNAs are essential components in regulating the gene expression of cancer cells. Especially miR21, which is a major player involved of tumor initiation, progression, invasion and metastasis in several cancers. The delivery of anti-miR21 sequences has significant potential for cancer treatment. Nevertheless, since anti-miR21 sequences are extremely unstable and they need to obtain certain concentration to function, it is intensely difficult to build an effective delivery system for them.The purpose of this work is to construct a self-assembled glutathione(GSH)-responsive system with tumor accumulation capacity for effective anti-miR21 delivery and cancer therapy. A novel drug delivery nanosphere carrying millions of anti-miR21 sequences was developed through the rolling circle transcription(RCT) method. GSH-responsive cationic polymer polyethyleneimine(pOEI) was synthesized to protect the nanosphere from degradation by Dicer or other RNase in normal cells and optimize the pompon-like nanoparticle to suitable size. Dehydroascorbic acid(DHA), a targeting molecule, which is a substrate of glucose transporter 1(GLUT 1) and highly expressed on malignant tumor cells, was connected to pOEI through PEG, and then the polymer was used for contracting a RNA nanospheres into nanopompons. The anti-miR21 nanopompons showed its potential for effective cancer therapy. | Qin Guo Chao Li Wenxi Zhou Xinli Chen Yu Zhang Yifei Lu Yujie Zhang Qinjun Chen Donghui Liang Tao Sun Chen Jiang | 2019 | Acta Pharmaceutica Sinica B2019，9，4： | 5 |
| 6 | Temperature-induced Lifshitz transition in topological insulator candidate HfTe_5显示文摘The ongoing discoveries and studies of novel topological quantum materials have become an emergent and important field of condensed matter physics.Recently,HfTe_5 ignited renewed interest as a candidate of a novel topological material.The single-layer HfTe_5 is predicted to be a two-dimensional large band gap topological insulator and can be stacked into a bulk that may host a temperature-driven topological phase transition.Historically,HfTe_5 attracted considerable interest for its anomalous transport properties characterized by a peculiar resistivity peak accompanied by a sign reversal carrier type.The origin of the transport anomaly remains under a hot debate.Here we report the first high-resolution laser-based angle-resolved photoemission measurements on the temperature-dependent electronic structure in HfTe_5.Our results indicated that a temperature-induced Lifshitz transition occurs in HfTe_5,which provides a natural understanding on the origin of the transport anomaly in HfTe_5.In addition,our observations suggest that HfTe_5 is a weak topological insulator that is located at the phase boundary between weak and strong topological insulators at very low temperature. | Yan Zhang Chenlu Wang Guodong Liu Aiji Liang Lingxiao Zhao Jianwei Huang Qiang Gao Bing Shen Jing Liu Cheng Hu Wenjuan Zhao Genfu Chen Xiaowen Jia Li Yu Lin Zhao Shaolong He Fengfeng Zhang Shenjin Zhang Feng Yang Zhimin Wang Qinjun Peng Zuyan Xu Chuangtian Chen Xingjiang Zhou | 2017 | Science Bulletin2017，62，13： | 4 |
| 7 | Lithiated Nafion-garnet ceramic composite electrolyte membrane for solid-state lithium metal battery显示文摘Single-ion conducting solid polymer electrolytes are expected to play a vital role in the realization of solid-state Li metal batteries.In this work,a lithiated Nafion(Li-Nafion)-garnet ceramic Li6.25La3 Zr2 Al0.25O12(LLZAO)composite solid electrolyte(CSE)membrane with 30μm thickness was prepared for the first time.By employing X-ray photoelectron spectroscopy and transmission electron microscope,the interaction between LLZAO and Li-Nafion was investigated.It is found that the LLZAO interacts with the Li-Nafion to form a space charge layer at the interface between LLZAO and Li-Nafion.The space charge layer reduces the migration barrier of Li-ions and improves the ionic conductivity of the CSE membrane.The CSE membrane containing 10 wt%LLZAO exhibits the highest ionic conductivity of2.26×10-4 S cm-1 at 30℃among the pristine Li-Nafion membrane,the membrane containing 5 wt%,20 wt%,and 30 wt%LLZAO,respectively.It also exhibits a high Li-ion transference number of 0.92,and a broader electrochemical window of 0-+4.8 V vs.Li+/Li than that of 0-+4.0 V vs.Li+/Li for the pristine Li-Nafion membrane.It is observed that the CSE membrane not only inhibits the growth of Li dendrites but also keeps excellent electrochemical stability with the Li electrode.Benefitting from the above merits,the solid-state LiFePO4/Li cell fabricated with the CSE membrane was practically charged and discharged at 30℃.The cell exhibits an initial reversible discharge specific capacity of 160 mAh g-1 with 97%capacity retention after 100 cycles at 0.2 C,and maintains discharge specific capacity of 126 mAh g-1 after500 cycles at 1 C.The CSE membrane prepared with Li-Nafion and LLZAO is proved to be a promising solid electrolyte for advanced solid-state Li metal batteries. | Jing Gao Qinjun Shao Jian Chen | 2020 | Journal of Energy Chemistry2020，29，7： | 3 |
| 8 | Incorporation of layered tin(Ⅳ) phosphate in graphene framework for high performance lithium-sulfur batteries显示文摘To anchor the polysulfide and enhance the conversion kinetics of polysulfide to disulfide/sulfide is critical for improving the performance of lithium-sulfur battery.For this purpose,the graphene-supported tin(Ⅳ) phosphate(Sn(HPO_4)_2·H_2 O,SnP) composites(SnP-G) are employed as the novel sulfur hosts in this work.When compared to the graphene-sulfur and carbon-sulfur composites,the SnP-G-sulfur composites exhibit much better cycling performance at 1.0 C over 800 cycles.Meanwhile,the pouch cell fabricated with the SnP-G-sulfur cathodes also exhibits excellent performance with an initial capacity of1266.6 mAh g^(-1)(S) and capacity retention of 76.9% after 100 cycles at 0.1 C.The adsorption tests,density functional theory(DFT) calculations in combination with physical cha racterizations and electrochemical measurements provide insights into the mechanism of capture-accelerated conversion mechanism of polysulfide at the surface of SnP.DFT calculations indicate that the Li-O bond formed between Li atom(from Li_2 S_n,n=1,2,4,6,8) and O atom(from PO_3-OH in SnP) is the main reason for the strong interactions between Li_2 S_n and SnP.As a result,SnP can effectively restrain the shuttle effect and improving the cycling performance of Li-S cell.In addition,by employing the climbing-image nudged elastic band(ciNEB) methods,the energy barrier for lithium sulfide decomposition(charging reaction) on SnP is proved to decrease significantly compared to that on graphene.It can be concluded that SnP is an effective sulfur hosts acting as dual-functional accelerators for the conversion reactions of polysulfude to sulfide(discharging reaction) as well as polysulfide to sulfur(charging reaction). | Haifeng Yuan Na Zhang Leiwu Tian Lei Xu Qinjun Shao Syed Danish Ali Zaidi Jianping Xiao Jian Chen | 2021 | Journal of Energy Chemistry2021，30，2： | 2 |
| 9 | Application of remote sensing for investigating mining geological hazards显示文摘To investigate geological mining hazards using digital techniques such as highresolution remote sensing,a semi-automatically geological mining hazards extraction method is proposed based on the case of the Shijiaying coal mine,located in Fangshan District,Beijing,China.In the method,the vegetation is first removed using the normalized difference vegetation index(NDVI)on the GeoEye-1 data.Then,geological mining hazards interpretation features are determined after color enhancement using principal component analysis(PCA)transformation.Bitmaps mainly covered by geological mining hazards are isolated by masking operation in the environment for visualizing images software.Next,each bitmap is classified into a two-valued imagery using support vector machine algorithm.In the two-valued imagery,1 denotes the geological mining hazards,while 0 denotes none.Afterwards,the two-valued imagery is converted into a vector graph by corresponding functions in the ArcGIS software and no geological mining hazards regions in the vector graph are deleted manually.Finally,the correlation between factors(such as mining activity,lithology,geological structure,and slope)and geological mining hazards is analyzed using a logistic regression and a hazardous-area forecasting model is built.The results of field verification show that the accuracy of the geological mining hazards extraction method is 98.1%and the results of the hazardous-area forecasting indicate that the logistic regression is an effective model in assessing geological hazard risks and that mining activity is the main contributing factor to the hazards,while geological structure,slope,lithology,roughness of the surface,and aspect are the secondary. | Qinjun Wang Huadong Guo Yu Chen Qizhong Lin Hui Li | 2013 | International Journal of Digital Earth2013，6，5： | 1 |

| 11 | Emergence of superconductivity from fully incoherent normal state in an iron-based superconductor (Ba_(0.6)K_(0.4))Fe_2As_2显示文摘In unconventional superconductors, it is generally believed that understanding the physical properties of the normal state is a pre-requisite for understanding the superconductivity mechanism. In conventional superconductors like niobium or lead, the normal state is a Fermi liquid with a well-defined Fermi surface and well-defined quasipartcles along the Fermi surface. Superconductivity is realized in this case by the Fermi surface instability in the superconducting state and the formation and condensation of the electron pairs(Cooper pairing). The high temperature cuprate superconductors, on the other hand, represent another extreme case that superconductivity can be realized in the underdoped region where there is neither well-defined Fermi surface due to the pseudogap formation nor quasiparticles near the antinodal regions in the normal state. Here we report a novel scenario that superconductivity is realized in a system with well-defined Fermi surface but without quasiparticles along the Fermi surface in the normal state.High resolution laser-based angle-resolved photoemission measurements have been performed on an optimally-doped iron-based superconductor(Ba_(0.6)K_(0.4))Fe_2As_2. We find that, while sharp superconducting coherence peaks emerge in the superconducting state on the hole-like Fermi surface sheets, no quasiparticle peak is present in the normal state. Its electronic behaviours deviate strongly from a Fermi liquid system. The superconducting gap of such a system exhibits an unusual temperature dependence that it is nearly a constant in the superconducting state and abruptly closes at Tc. These observations have provided a new platform to study unconventional superconductivity in a non-Fermi liquid system. | Jianwei Huang Lin Zhao Cong Li Qiang Gao Jing Liu Yong Hu Yu Xu Yongqing Cai Dingsong Wu Ying Ding Cheng Hu Huaxue Zhou Xiaoli Dong Guodong Liu Qingyan Wang Shenjin Zhang Zhimin Wang Fengfeng Zhang Feng Yang Qinjun Peng Zuyan Xu Chuangtian Chen Xingjiang Zhou | 2019 | Science Bulletin2019，64，1： | 1 |

| 14 | A review on lithium-sulfur batteries:Challenge,development,and perspective显示文摘Lithium-sulfur(Li-S)battery is recognized as one of the promising candidates to break through the specific energy limitations of commercial lithium-ion batteries given the high theoretical specific energy,environmental friendliness,and low cost.Over the past decade,tremendous progress have been achieved in improving the electrochemical performance especially the lifespan by various strategies mainly concentrated on the sulfur cathodes.In this review,the fundamental electrochemistry of sulfur cathode and lithium anode is revealed to understand the current dilemmas.And the advances achieved through diverse strategies are comprehensively summarized,which involves lithium polysulfides(LiPSs)limitation,sulfur redox reaction regulation and electrocatalysis in sulfur cathode and artificial solid electrolyte interface(SEI),electrolyte design,and structured anode in lithium anode.Additionally,the differences between laboratory level coin cells and actual pouch cells need to be addressed that only few reports on practical Li-S pouch cell are available due to the unexpected problems on both sulfur cathode and lithium anode which are masked at lithium and electrolyte excess.Lastly,the challenges and perspective toward the practical Li-S batteries are also offered. | Qinjun Shao Shengdong Zhu Jian Chen | 2023 | Nano Research2023，16，6： | 1 |

| 16 | The effect of oxygen on the epitaxial growth of diamond显示文摘We studied the effect of oxygen on the growth quality of diamond epitaxial layers. After oxygen is added during the growth of the diamond epitaxial layer, as the thickness of the epitaxial layer increases, the full width at half maximum of the rocking curve of the(004) plane of diamond epitaxial layer increases continuously, and, in addition, the intensities of both the Raman peaks and the free exciton emission peaks of the diamond epitaxial layer decrease continuously. These experimental results demonstrate that as the thickness of the diamond epitaxial layer increases, the quality of the diamond epitaxial layer degrades. The strong etching effect of the OH radical groups in the plasma on the diamond epilayers leads to the degradation of their crystallinity. | Meng Gong Yanan Chen Wancheng Yu Peng Jin Zhanguo Wang Zhimin Wang Shenjin Zhang Feng Yang Fengfeng Zhang Qinjun Peng Zuyan Xu | 2018 | Journal of Semiconductors2018，39，12： | 1 |

Conclusion: A1555G and 961insC mutations in mitochondrial DNA 12S rRNA gene regions may play a role in the pathogenesis of hearing loss in the sporadic cases. | Xia Xu Guangqian Xing Qinjun Wei Zhibin Chen Hongbo Cheng Xin Cao Xingkuan Bu | 2006 | Journal of Nanjing Medical University2006，20，5： | 1 |
| 19 | The importance of proleptic branch traits in biomass production of poplar in high-density plantations显示文摘Branch phenotypic traits determine tree crown architecture,which in turn governs leaf display,light interception,and biomass production.Sylleptic and proleptic branches are the obviously different branch phenotypes in the poplar crown.Many studies have focused on the influence of sylleptic branch numbers(SBN)on biomass production,but the research on the influence of proleptic branch phenotypes was only a few.To explore the relationship between proleptic branch traits and biomass generation production in a high-density poplar plantation,we investigated the branch phenotypic traits of three poplar genotypes,all of which have high survival rates in forests(>95%)and significantly different crown architecture and biomass performance in the high-density plantations(1667 stems ha−1).The plantation site was established in 2007.A terrestrial laser scanner was used to measure branch characteristics such as length,angle of origin and termination,and azi-muth angle.A hierarchical cluster analysis performed on branch characteristics showed that SBN,crown depth,and proleptic branch curvature(PBC)were clustered with bio-mass production and leaf area index(LAI).Among all of the monitored traits,PBC played the second most important role in biomass production after SBN and was significantly correlated with SBN,LAI,and biomass production.The positive correlation between PBC and SBN indicated that a larger PBC was associated with more sylleptic branches within the monitored genotypes planted in the high-density plantation,providing greater leaf area and biomass produc-tion.The results of this study will improve the identification of high-production poplar varieties for cultivation in high-density plantations for biofuel production. | Changjun Ding Ningning Wang Qinjun Huang Weixi Zhang Juan Huang Suli Yan Boyi Chen Dejun Liang Yufeng Dong Yingbai Shen Xiaohua Su | 2022 | Journal of Forestry Research2022，33，2： | 1 |
| 20 | Recent Advancements in Nanomedicine for‘Cold’Tumor Immunotherapy显示文摘Although current anticancer immunotherapies using immune checkpoint inhibitors(ICIs)have been reported with a high clinical success rate,numerous patients still bear‘cold’tumors with insufficient T cell infiltration and low immunogenicity,responding poorly to ICI therapy.Considering the advancements in precision medicine,in-depth mechanism studies on the tumor immune microenvironment(TIME)among cold tumors are required to improve the treatment for these patients.Nanomedicine has emerged as a promising drug delivery system in anticancer immunotherapy,activates immune function,modulates the TIME,and has been applied in combination with other anticancer therapeutic strategies.This review initially summarizes the mechanisms underlying immunosuppressive TIME in cold tumors and addresses the recent advancements in nanotechnology for cold TIME reversal-based therapies,as well as a brief talk about the feasibility of clinical translation. | Qinjun Chen Tao Sun Chen Jiang | 2021 | Nano-Micro Letters2021，13，6： | 1 |
