| 1 | RESTplus: an improved toolkit for resting-state functional magnetic resonance imaging data processing显示文摘Resting-state functional magnetic resonance imaging (RS-fMRI)[1,2] provides relatively high spatial and temporal resolution for mapping spontaneous brain activity non-invasively. It has been widely used in cognitive neuroscience and clinical studies. A number of comprehensive software packages have been developed for RS-fMRI data analysis, among which a MATLAB package named REST (RESing-state fMRI data analysis Toolkit, released in October 2008 at http://gffzz99d25abdda23474bh05knvof9b6c665qk.ffgz.tsg.suse.edu.cn)[3] is the earliest one dedicated to RS-fMRI analysis. REST focuses on RS-fMRI postprocessing metrics. | Xi-Ze Jia Jue Wang Hai-Yang Sun Han Zhang Wei Liao Ze Wang Chao-Gan Yan Xiao-Wei Song Yu-Feng Zang | 2019 | Science Bulletin2019，64，14： | 14 |
| 2 | Apolipoprotein E, amyloid-beta, and neuroinflammation in Alzheimer's disease显示文摘Alzheimer's disease(AD) is characterized by the accumulation and deposition of amyloid-beta(Aβ) peptides in the brain. Neuroinflammation occurs in the AD brain and plays a critical role in the neurodegenerative pathology. Particularly, Aβ evokes an inflammatory response that leads to synaptic dysfunction, neuronal death, and neurodegeneration. Apolipoprotein E(ApoE) proteins are involved in cholesterol transport, Aβ binding and clearance, and synaptic functions in the brain. The ApoE4 isoform is a key risk factor for AD, while the ApoE2 isoform has a neuroprotective effect. However, studies have reached different conclusions about the roles of the isoforms; some show that both ApoE3 and ApoE4 have anti-infl ammatory effects, while others show that ApoE4 causes a predisposition to inflammation or promotes an inflammatory response following lipopolysaccharide treatment. These discrepancies may result from the differences in models, cell types, experimental conditions, and inflammatory stimuli used. Further, little was known about the role of ApoE isoforms in the Aβ-induced inflammatory response and in the neuroinflammation of AD. Our recent work showed that ApoE isoforms differentially regulate and modify the Aβ-induced infl ammatory response in neural cells, with ApoE2 suppressing and ApoE4 promoting the response. In this article, we review the roles, mechanisms, and interrelations among Aβ, ApoE, and neuroinfl ammation in AD. | Evan Dorey Nina Chang Qing Yan Liu Ze Yang Wandong Zhang | 2014 | Neuroscience Bulletin2014，30，2： | 9 |
| 3 | Identification of biomarkers for hepatocellular carcinoma by semiquantitative immunocytochemistry显示文摘AIM:To investigate the expression of key biomarkers in hepatoma cell lines,tumor cells from patients’blood samples,and tumor tissues.METHODS:We performed the biomarker tests in two steps.First,cells plated on coverslips were used to assess biomarkers,and fluorescence intensities were calculated using the NIH Image J software.The measured values were analyzed using the SPSS19.0 software to make comparisons among eight cell lines.Second,eighty-four individual samples were used to assess the biomarkers’expression.Negative enrichment of the blood samples was performed,and karyocytes were isolated and dropped onto pretreated glass slides for further analysis by immunofluorescence staining.Fluorescence intensities were compared among hepatocellular carcinoma(HCC)patients,chronic HBV-infected patients,and healthy controls following methods similar to those used for cell lines.The relationships between the expression of biomarkers and clinical pathological parameters were analyzed by Spearman rank correlation tests.In addition,we studied the distinct biomarkers’expression with three-dimensional laser confocal microscopy reconstructions,and Kaplan-Meier survival analysis was performed to understand the clinical significance of these biomarkers.RESULTS:Microscopic examination and fluorescence intensity calculations indicated that cytokeratin 8/18/19(CK)expression was significantly higher in six of the seven HCC cell lines examined than in the control cells,and the expression levels of asialoglycoprotein receptor(ASGPR)and glypican-3(GPC3)were higher in all seven HCC cell lines than in the control.Cells obtained from HCC patients’blood samples also displayed significantly higher expression levels of ASGPR,GPC3,and CK than cells from chronic HBV-infected patients or healthy controls;these proteins may be valuable surface biomarkers for identifying HCC circulating tumor cells isolated and enriched from the blood samples.The stem cell-like and epithelial-mesenchymal transition-related biomarkers could be detected on the karyocyte slides.ASGPR and GPC3 were expressed at high levels,and thus three-dimensional reconstructions were used to observe their expression in detail.This analysis indicated that GPC3 was localized in the cytoplasm and membrane,but that ASGPR had a polar localization.Survival analyses showed that expression of GPC3 and ASGPR is associated with a patient’s overall survival(OS).CONCLUSION:ASGPR,GPC3,and CK may be valuable HCC biomarkers for CTC detection;the expression of ASGPR and GPC3 might be helpful for understanding patients’OS. | Hong Mu Kai-Xuan Lin Hong Zhao Shu Xing Cong Li Fang Liu Hai-Zhen Lu Ze Zhang Yu-Lin Sun Xi-Yun Yan Jian-Qiang Cai Xiao-Hang Zhao | 2014 | World Journal of Gastroenterology2014，20，19： | 8 |

| 5 | Effect of glial cells on remyelination after spinal cord injury显示文摘Remyelination plays a key role in functional recovery of axons after spinal cord injury.Glial cells are the most abundant cells in the central nervous system.When spinal cord injury occurs,many glial cells at the lesion site are immediately activated,and different cells differentially affect inflammatory reactions after injury.In this review,we aim to discuss the core role of oligodendrocyte precursor cells and crosstalk with the rest of glia and their subcategories in the remyelination process.Activated astrocytes influence proliferation,differentiation,and maturation of oligodendrocyte precursor cells,while activated microglia alter remyelination by regulating the inflammatory reaction after spinal cord injury.Understanding the interaction between oligodendrocyte precursor cells and the rest of glia is necessary when designing a therapeutic plan of remyelination after spinal cord injury. | Hai-feng Wang Xing-kai Liu Rui Li Ping Zhang Ze Chu Chun-li Wang Hua-rui Liu Jun Qi Guo-yue Lv Guang-yi Wang Bin Liu Yan Li Yuan-yi Wang | 2017 | Neural Regeneration Research2017，12，10： | 6 |
| 6 | Molecular diversity analysis of Tetradium ruticarpum(Wu Zhu Yu) in China based on inter-primer binding site(iPBS) markers and inter-simple sequence repeat(ISSR) markers显示文摘'Wu zhu yu', which is obtained from the dried unripe fruits of Tetradium ruticarpum(A. Jussieu) T. G. Hartley, has been used as a traditional Chinese medicine for treatment of headaches, abdominal colic, and hypertension for thousands of years. The present study was designed to assess the molecular genetic diversity among 25 collected accessions of T. ruticarpum(Wu zhu yu in Chinese) from different areas of China, based on inter-primer binding site(i PBS) markers and inter-simple sequence repeat(ISSR) markers. Thirteen ISSR primers generated 151 amplification bands, of which 130 were polymorphic. Out of 165 bands that were amplified using 10 iPBS primers, 152 were polymorphic. The iPBS markers displayed a higher proportion of polymorphic loci(PPL = 92.5%) than the ISSR markers(PPL = 84.9%). The results showed that T. ruticarpum possessed high loci polymorphism and genetic differentiation occurred in this plant. The combined data of iPBS and ISSR markers scored on 25 accessions produced five clusters that approximately matched the geographic distribution of the species. The results indicated that both iPBS and ISSR markers were reliable and effective tools for analyzing the genetic diversity in T. ruticarpum. | XU Jing-Yuan ZHU Yan YI Ze WU Gang XIE Guo-Yong QIN Min-Jian | 2018 | Chinese Journal of Natural Medicines2018，16，1： | 5 |

| 8 | Adaptive target and jamming recognition for the pulse doppler radar fuze based on a time-frequency joint feature and an online-updated naive bayesian classifier with minimal risk显示文摘This paper considers the problem of target and jamming recognition for the pulse Doppler radar fuze(PDRF).To solve the problem,the matched filter outputs of the PDRF under the action of target and jamming are analyzed.Then,the frequency entropy and peak-to-peak ratio are extracted from the matched filter output of the PDRF,and the time-frequency joint feature is constructed.Based on the time-frequency joint feature,the naive Bayesian classifier(NBC)with minimal risk is established for target and jamming recognition.To improve the adaptability of the proposed method in complex environments,an online update process that adaptively modifies the classifier in the duration of the work of the PDRF is proposed.The experiments show that the PDRF can maintain high recognition accuracy when the signal-to-noise ratio(SNR)decreases and the jamming-to-signal ratio(JSR)increases.Moreover,the applicable analysis shows that he ONBCMR method has low computational complexity and can fully meet the real-time requirements of PDRF. | Jian Dai Xin-hong Hao Ze Li Ping Li Xiao-peng Yan | 2022 | Defence Technology(防务技术)2022，18，3： | 4 |

| 10 | Fluid Inclusion and Geochemistry Studies of Calcite Veins in Shizhu Synclinorium,Central China:Record of Origin of Fluids and Diagenetic Conditions显示文摘Calcite veins in carbonate fracture have been investigated by petrographic, fluid inclusion, geochemical analyses and coupled with basin modeling techniques to provide useful insights into fluid activity and deformation conditions of the Cambrian to Triassic Shizhu synclinorium from the western region of Mid-Yangtze, central China. The results of the fluid inclusion microthermometry show a wide range of homogenization temperatures(78.6–215.5 °C) and salinities(0.18–23.11 wt.% NaCl equivalent), indicating the formation under diverse fluid conditions. All the calcite veins have negative Ce anomalies, which are the typical characteristic of marine carbonate sediments; it is therefore plausible that calcite veins were precipitated from the marine basin fluid. The stable carbon isotopic compositions of calcites(δ^(13)CV-PDB=-2.5‰–4.26‰) and host limestones(δ^(13)CV-PDB=-3.56‰–5.80‰) are very similar with a correlation coefficient of 0.86, however, four calcites from the Lower Permian and Lower Triassic show lower δ^(13)C values relative to the host limestones, and they are depleted in total REE concentrations(∑REE ratio varies from 0.74 to 2.06), suggesting the derivation of dissolved carbon from marine carbonates hosting the calcite veins and, less commonly, from the degradation of organic matter. Calculated δ^(18)O of the fluids-precipitating calcites(δ^(18)OV-SMOW=-0.41‰–14.42‰), ^(87)Sr/^(86)Sr ratios varying in the range of coeval seawater and the distinct REE pattern simultaneously suggest calcite-forming fluids in each stratigraphic unit could have formed from the involvement of fluids that originated from coeval seawater and evolved through different degrees of water rock interaction. However, the presence of more radiogenic ^(87)Sr/^(86)Sr ratios than coeval seawater and pronounced positive Eu anomalies in calcites of Lower to Middle Ordovician rocks indicate that terrestrial input from upper strata mudstone and siliciclastic rocks could be involved in the precipitation of the Ordovician calcite. Fluid-inclusion data combined with burial and thermal history modeling indicate there was large-scale flow of evolved basinal fluids through the carbonate formation fractures spanning a time frame from 135 to 50 Ma(Early Cretaceous–Eocene). Therefore, the geochemical characteristics of calcite veins can provide the basis for deformation events in Late Yanshanian and Early Himalayan orogeny. | Xiao Wang Jian Gao Sheng He Zhiliang He Yan Zhou Ze Tao Jiankun Zhang Yi Wang | 2017 | Journal of Earth Science2017，28，2： | 4 |
| 11 | Generation of tryptophan hydroxylase 2 gene knockout pigs by CRISPR/Cas9-mediated gene targeting显示文摘Unbalanced brain serotonin(5-HT) levels have implications in various behavioral abnormalities and neuropsychiatric disorders. The biosynthesis of neuronal 5-HT is regulated by the rate-limiting enzyme, tryptophan hydroxylase-2(TPH2). In the present study, the clustered regularly interspaced short palindromic repeat(CRISPR)/CRISPR-associated(Cas) system was used to target the Tph2 gene in Bama mini pig fetal fibroblasts. It was found that CRISPR/Cas9 targeting efficiency could be as high as 61.5%, and the biallelic mutation efficiency reached at38.5%. The biallelic modified colonies were used as donors for somatic cell nuclear transfer(SCNT) and 10 Tph2 targeted piglets were successfully generated. These Tph2 KO piglets were viable and appeared normal at the birth.However, their central 5-HT levels were dramatically reduced, and their survival and growth rates were impaired before weaning. These Tph2 KO pigs are valuable large-animal models for studies of 5-HT deficiency induced behavior abnomality. | Ze Li Hai-Yuan Yang Ying Wang Man-Ling Zhang Xiao-Rui Liu Qiang Xiong Li-Ning Zhang Yong Jin Li-Sha Mou Yan Liu Rong-Feng Li Yi Rao Yi-Fan Dai | 2017 | The Journal of Biomedical Research2017，31，5： | 4 |

| 13 | Exosomal PD-L1 induces osteogenic differentiation and promotes fracture healing by acting as an immunosuppressant显示文摘A moderate inflammatory response at the early stages of fracture healing is necessary for callus formation.Over-active and continuous inflammation,however,impairs fracture healing and leads to excessive tissue damage.Adequate fracture healing could be promoted through suppression of local over-active immune cells in the fracture site.In the present study,we achieved an enriched concentration of PD-L1 from exosomes(Exos)of a genetically engineered Human Umbilical Vein Endothelial Cell(HUVECs),and demonstrated that exosomes overexpressing PD-L1 specifically bind to PD-1 on the T cell surface,suppressing the activation of T cells.Furthermore,exosomal PD-L1 induced Mesenchymal Stem Cells(MSCs)towards osteogenic differentiation when pre-cultured with T cells.Moreover,embedding of Exos into an injectable hydrogel allowed Exos delivery to the surrounding microenvironment in a time-released manner.Additionally,exosomal PD-L1,embedded in a hydrogel,markedly promoted callus formation and fracture healing in a murine model at the early over-active inflammation phase.Importantly,our results suggested that activation of T cells in the peripheral lymphatic tissues was inhibited after local administration of PD-L1-enriched Exos to the fracture sites,while T cells in distant immune organs such as the spleen were not affected.In summary,this study provides the first example of using PD-L1-enriched Exos for bone fracture repair,and highlights the potential of Hydrogel@Exos systems for bone fracture therapy through immune inhibitory effects. | Ze Lin Yuan Xiong Weilin Meng Yiqiang Hu Lili Chen Lang Chen Hang Xue Adriana CPanayi Wu Zhou Yun Sun Faqi Cao Guodong Liu Liangcong Hu Chenchen Yan Xudong Xie Chuanchuan Lin Kaiyong Cai Qian Feng Bobin Mi Guohui Liu | 2022 | Bioactive Materials2022，7，7： | 4 |

| 15 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 3 |
| 16 | Optimal Waist Circumference Cut-off values for Identifying Metabolic Risk Factors in Middle-aged and Elderly Subjects in Shandong Province of China显示文摘Objective To study the optimal waist circumference(WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome(MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China. | HOU Xin Guo WANG Chuan MA Ze Qiang YANG Wei Fang WANG Ji Xiang LI Cheng Qiao WANG Yu Lian LIU Shu Min Hu Xiu Ping ZHANG Xiu Ping JIANG Mei WANG Wei Qing NING Guang ZHENG Hui Zhen MA Ai Xia SUN Yu SONG Jun LIN Peng LIANG Kai LIU Fu Qiang LI Wen Juan XIAO Juan GONG Lei WANG Mei Jian LIU Ji Dong YAN Fei YANG Jun Peng WANG Ling Shu TIAN Meng ZHAO Ru Xing JIANG Ling CHEN Li | 2014 | Biomedical and Environmental Sciences2014，27，5： | 3 |
| 17 | Influence of Dust Accumulation on the Solar Reflectivity of a Linear Fresnel Reflector显示文摘Solar reflecting and heat collecting systems are generally operated outdoors year-round,and the optical performance of the reflector is reduced by dust accumulation on the surface.In this study,the dust accumulation on a linear Fresnel reflector was investigated.The relative reflectivity of the mirror before and after dust accumulation and the physical and chemical characteristics of the dust were measured using an ultraviolet spectrophotometer,scanning electron microscope,and X-ray diffractometer.The results showed that the dust density on the mirror increased,and the relative reflectivity decreased with an increase in the dust accumulation time.During 48 days of dust accumulation,the average relative reflectivity decreased 9.4%for a 1 g/m^(2)increase in the dust density.Additionally,the dust density on the mirror increased while the relative reflectivity decreased with a decrease in the mirror tilt angle.The rate of decrease of the relative reflectivity was higher for the aluminum mirror than that of the silver mirror after dust accumulation.The main component of the dust particles in the test area was SiO_(2),and the particle size range of the dust was 0.9 um to 87µm.According to the physical and chemical properties of the dust and the shielding effect of the dust on the mirror,a model to predict the influence of natural dust accumulation on the relative reflectivity of the linear Fresnel reflector was proposed.The predicted results deviated about 1%from the test results. | ZHAO Xiaoyan CHEN Zhuang YAN Suying MING Tingzhen WU Ze MA Rui | 2021 | Journal of Thermal Science2021，30，5： | 3 |

| 19 | Insulin-like growth factor 1-induced enolase 2 deacetylation by HDAC3 promotes metastasis of pancreatic cancer显示文摘Enolase 2(ENO2)is a key glycolytic enzyme in the metabolic process of glycolysis,but its potential function in pancreatic ductal adenocarcinoma(PDAC)is unclear.In this study,we observed a significant overexpression of ENO2 in PDAC tissues,and its expression was correlated with metastasis and poor prognosis in PDAC patients.K394 was identified as a major acetylation site in ENO2 that regulates its enzymatic activity,cell metabolism and PDAC progression.Knockdown of ENO2 suppressed tumor growth and liver metastasis in PDAC.Re-expression of wild-type(WT)ENO2,but not the K394 acetylation mimetic mutant,could reverse the decreased tumor malignancy.We further characterized histone deacetylase 3(HDAC3)and P300/CBP-associated factor(PCAF)as the potential deacetylase and acetyltransferase for ENO2,respectively.HDAC3-mediated deacetylation was shown to lead to ENO2 activation and enhancement of glycolysis.Importantly,insulin-like growth factor-1(IGF-1)was found to decrease K394 acetylation and stimulate ENO2 activity in a dose-and time-dependent manner.The PI3K/AKT/mTOR pathway facilitated the phosphorylation of HDAC3 on S424,which promoted K394 deacetylation and activation of ENO2.Linsitinib,an oral small-molecule inhibitor of IGF-1R,could inhibit IGF-1-induced ENO2 deacetylation by HDAC3 and the PI3K/AKT/mTOR pathway.Furthermore,linsitinib showed a different effect on the growth and metastasis of PDAC depending on the overexpression of WT versus K394-mutant ENO2.Our results reveal a novel mechanism by which acetylation negatively regulates ENO2 activity in the metastasis of PDAC by modulating glycolysis.Blockade of IGF-1-induced ENO2 deacetylation represents a promising strategy to prevent the development of PDAC. | Yan Zheng Chao Wu Jimeng Yang Yue Zhao Huliang Jia Min Xue Da Xu Feng Yang Deliang Fu Chaoqun Wang Beiyuan Hu Ze Zhang Tianen Li Shican Yan Xuan Wang Peter J.Nelson Christiane Bruns Lunxiu Qin Qiongzhu Dong | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 3 |
| 20 | Preparation of multihollow P(St-MAA) particles by sequence soap-free/soap emulsion polymerization and followed by stepwise alkali/acid posttreatment显示文摘The effects of ionic emulsifier, sodium dodecylbenzene sulfate (SDBS), on the formation of the multihollow structures in sub-micron sized polymer particles produced by alkali/acid posttreatment were investigated. The original latex particles with narrow size distribution were synthesized by a new sequence emulsifier-free/emulsifier emulsion copolymerization of styrene (St) and methacrylic acid (MAA). Results indicated that the pore size decreased and the pore number increased with the increase of SDBS amount, and the morphology of the posttreated latex particles was also significantly influenced by the introducing time of SDBS in the preparation of the original latex particles, and a suitable introducing time was 3 h of polymerization. | Rong Long Li Cheng You Kan Ze Ping Li Yi Du Yan Nan Cui | 2007 | Chinese Chemical Letters2007，18，6： | 3 |
