| 1 | The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus. | Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang | 2016 | Science China(Life Sciences)2016，59，9： | 5 |
| 2 | Propofol attenuates high glucose-induced P66shc expression in human umbilical vein endothelial cells through Sirt1显示文摘Perioperative hyperglycemia is a common metabolic disorder in clinic settings.Hyperglycemia leads to endothelial inflammation,endothelial cell apoptosis,and dysfunction,thus resulting in endothelial injury.Propofol(2,6-diisopropylphenol)is a widely used intravenous anesthetic in clinic settings.Our previous study indicated that propofol inhibits mitochondrial reactive oxygen species(ROS)production via down-regulation of phosphatase A2(PP2A)expression,inhibition of Ser36-p66shc dephosphorylation and mitochondrial translocation,thus improving high glucose-induced endothelial injury.The expression of p66shc was inhibited by propofol in hyperglycemic human umbilical vein endothelial cells(HUVECs).However,the mechanism by which propofol inhibits p66shc expression in hyperglycemic HUVECs is still obscure.In the present study,we mainly examined how propofol inhibited high glucose-induced p66shc expression in HUVECs.Compared with 5 mM glucose treatment,high glucose increased p66shc expression and decreased sirt1 expression,which was inhibited by propofol treatment.Moreover,EX527(a sirt1 inhibitor)reversed the effect of propofol against high glucose-induced p66shc expression.However,EX527 did not reverse the effects of propofol against high glucose-induced ROS accumulation,endothelial inflammation,and apoptosis.Furthermore,when cells were incubated with propofol,EX527,and FTY720(a PP2A activator)simultaneously,the effects of propofol against high glucose-induced ROS accumulation,inflammation,and apoptosis were reversed.Our results suggested that propofol inhibited high glucose-induced p66shc expression via upregulation of sirt1 expression in hyperglycemic HUVECs.Moreover,propofol protects against high glucose-mediated ROS accumulation and endothelial injury via both inhibition of p66shc expression and dephosphorylation of Ser36-p66shc. | Jing Wang Jie Qi Qichao Wu Hui Jiang Yuehao Yin Yan Huanx Yanjun Zhao Minmin Zhu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，2： | 5 |
| 3 | Biochemistry of mammalian ferritins in the regulation of cellular iron homeostasis and oxidative responses显示文摘Ferritin,an iron-storage protein,regulates cellular iron metabolism and oxidative stress.The ferritin structure is characterized as a spherical cage,inside which large amounts of iron are deposited in a safe,compact and bioavailable form.All ferritins readily catalyze Fe(II)oxidation by peroxides at the ferroxidase center to prevent free Fe(II)from participating in oxygen free radical formation via Fenton chemistry.Thus,ferritin is generally recognized as a cytoprotective stratagem against intracellular oxidative damage.The expression of cytosolic ferritins is usually regulated by iron status and oxidative stress at both the transcriptional and post-transcriptional levels.The mechanism of ferritin-mediated iron recycling is far from clarified,though nuclear receptor co-activator 4(NCOA4)was recently identified as a cargo receptor for ferritin-based lysosomal degradation.Cytosolic ferritins are heteropolymers assembled by H-and L-chains in different proportions.The mitochondrial ferritins are homopolymers and distributed in restricted tissues.They play protective roles in mitochondria where heme-and Fe/S-enzymes are synthesized and high levels of ROS are produced.Genetic ferritin disorders are mainly related to the L-chain mutations,which generally cause severe movement diseases.This review is focused on the biochemistry and function of mammalian intracellular ferritin as the major iron-storage and anti-oxidation protein. | Jianlin Zhang Xuehui Chen Juanji Hong Aifa Tang Yang Liu Ni Xie Guohui Nie Xiyun Yan Minmin Liang | 2021 | Science China(Life Sciences)2021，64，3： | 5 |
| 4 | Carbon-based nanozymes for biomedical applications显示文摘Nanozymes are nanomaterials with enzyme-like properties that have attracted significant interest owing to their capability to address the limitations of traditional enzymes such as fragility,high cost,and impossible mass production.Over the past decade,a broad variety of nanomaterials have been found to mimic the enzyme-like activity by engineering the active centers of natural enzymes or developing multivalent elements within nanostructures.Carbon nanomaterials with well-defined electronic and geometric structures have served as favorable surrogates of traditional enzymes by mimicking the highly evolved catalytic center of natural enzymes.In particular,by combining the unique electronic,optical,thermal,and mechanical properties,carbon nanomaterials-based nanozymes can offer a variety of multifunctional platforms for biomedical applications.In this review,we will introduce the enzymatic characteristics and recent advances of carbon nanozymes,and summarize their significant applications in biomedicine. | Hui Ding Bing Hu Bin Zhang Han Zhang Xiyun Yan Guohui Nie Minmin Liang | 2021 | Nano Research2021，14，3： | 4 |
| 5 | Effect of Mn content on the microstructure and mechanical properties of Mg–6Li–4Zn-xMn alloys显示文摘The as-cast Mg–6Li–4Zn-x Mn alloys were prepared and extruded at 280℃with an extrusion ratio of 25:1.The effects of Mn content on the microstructure and mechanical properties of Mg–6Li–4Zn-x Mn alloys were investigated in this study.The XRD results show that Mg–6Li–4Zn–x Mn alloys consisted ofα-Mg(hcp)+β-Li(bcc)duplex structured matrix,Mg Li_(2)Zn and Mn phases.The grains of the extruded Mg–6Li–4Zn–x Mn alloys were refined by dynamic recrystallization during the extrusion process.The EBSD results show that the extruded alloys had basal textures.The grain size of the extruded alloys decreased while the basal texture was strengthened with the increasing Mn addition.The TEM results show that a large amount of nanoscale Mn precipitates existed in the extruded Mg–6Li–4Zn–1.2 Mn alloy,which can effectively inhibit the dynamic recrystallized(DRXed)grains growth during the hot extrusion and is beneficial to the improvement of mechanical properties.Mg–6Li–4Zn–1.2 Mn alloy in this research possesses the best mechanical properties with the ultimate tensile strength and yield strength of 321 MPa,250 MPa,respectively. | Hongju Deng Yan Yang Minmin Li Xiaoming Xiong Guobing Wei Weidong Xie Bin Jiang Xiaodong Peng Fusheng Pan | 2021 | Progress in Natural Science:Materials International2021，31，4： | 3 |
| 6 | Pharmacogenetic activation of midbrain dopaminergic neurons induces hyperactivity显示文摘Dopaminergic neurons regulate and organize numerous important behavioral processes including motor activity.Consistently,manipulation of brain dopamine concentrations changes animal activity levels.Dopamine is synthesized by several neuronal populations in the brain.This study was carried out to directly test whether selective activation of dopamine neurons in the midbrain induces hyperactivity.A pharmacogenetic approach was used to activate midbrain dopamine neurons,and behavioral assays were conducted to determine the effects on mouse activity levels.Transgenic expression of the evolved hM3Dq receptor was achieved by infusing Creinducible AAV viral vectors into the midbrain of DATCre mice.Neurons were excited by injecting the hM3Dq ligand clozapine-N-oxide(CNO).Mouse locomotor activity was measured in an open field.The results showed that CNO selectively activated midbrain dopaminergic neurons and induced hyperactivity in a dose-dependent manner,supporting the idea that these neurons play an important role in regulating motor activity. | Shujie Wang Yan Tan Ju-En Zhang Minmin Luo | 2013 | Neuroscience Bulletin2013，29，5： | 2 |
| 7 | Controllable synthesis of grain boundary-enriched Pt nanoworms decorated on graphitic carbon nanosheets for ultrahigh methanol oxidation catalytic activity显示文摘Although one-dimensional Pt nanocrystals have long been regarded as ideal electrode catalysts for fuel cells,the synthetic techniques commonly involve the use of various complicated templates or surfactants,which have largely hampered their large-scale industrial application.Herein,we present a convenient and cost-effective approach to the stereoassembly of quasi-one-dimensional grain boundary-enriched Pt nanoworms on nitrogen-doped low-defect graphitic carbon nanosheets(Pt NWs/NL-CNS).Benefiting from its numerous catalytically active grain boundaries as well as optimized electronic structure,the as-derived Pt NWs/NL-CNS catalyst possesses exceptionally good electrocatalytic properties for methanol oxidation,including an ultrahigh mass activity of 1949.5 mA mg^(-1), reliable long-term durability,and strong poison tolerance,affording one of the most active Pt-based electrocatalysts for methanol oxidation reaction.Density functional theory calculation further reveals that the formation of worm-shape Pt morphology is attributed to the modified electronic structure as well as controllable defect density of the carbon matrix,which could also weaken the adsorption ability of Pt towards CO molecule and meanwhile synergistically promotes the catalytic reaction kinetics. | Huajie Huang Yujie Wei Ying Yang Minmin Yan Haiyan He Quanguo Jiang Xiaofei Yang Jixin Zhu | 2021 | Journal of Energy Chemistry2021，30，6： | 2 |
| 8 | Bioengineered magnetoferritin nanozymes for pathological identification of high-risk and ruptured atherosclerotic plaques in humans显示文摘Atherosclerotic plaque rupture results in thrombus formation and vessel occlusion, and is the leading cause of death worldwide. There is a pressi ng need to identify plaque vuln erability for the treatment of carotid and coronary artery diseases. Nano materials with en zyme-like properties have attracted significant interest by providing biological, diagnostic and prognostic information about the diseases. Here we showed that bioe ngin eered mag netoferritin nan oparticles (M-HFn NPs) functionally mimic peroxidase en zyme and can intrin sically recog nize plaque-infiltrated active macrophages, which drive atherosclerotic plaque progression and rupture and are significantly associated with the plaque vulnerability. The M-HFn nanozymes catalyze the oxidation of colorimetric substrates to give a color reaction that visualizes the recognized active macrophages for one-step pathological identification of plaque vulnerability. We examined 50 carotid endarterectomy specimens from patients with symptomatic carotid disease and demonstrated that the M-HFn nanozymes could distinguish active macrophage infiltration in ruptured and high-risk plaque tissues, and M-HFn staining displayed a significant correlation with plaque vulnerability (r= 0.89, P< 0.0001). | Tao Wang Jiuyang He Demin Duan Bing Jiang Peixia Wang Kelong Fan Minmin Liang Xiyun Yan | 2019 | Nano Research2019，12，4： | 1 |
| 9 | Black phosphorus quantum dots as multifunctional nanozymes for tumor photothermal/catalytic synergistic therapy显示文摘Nanozymes are nanomaterials with enzyme-like properties that have attracted significant interest owing to their high stability,easy preparation,and tunable catalytic properties,especially in the field of cancer therapy.However,the unfavorable catalytic effects of nanozymes in the acidic tumor microenvironment have limited their applications.Herein,we developed a biomimetic erythrocyte membrane-camouflaged ultrasmall black phosphorus quantum dots(BPQDs)nanozymes that simultaneously exhibited an exceptional near-infrared(NIR)photothermal property and dramatically photothermal-enhanced glucose oxidase(GOx)-like activity in the acidic tumor microenvironment.We demonstrated the engineered BPQDs gave a photothermal conversion efficiency of 28.9%that could rapidly heat the tumor up to 50℃ while effectively localized into tumors via homing peptide iRGD leading after intravenously injection.Meanwhile,the significantly enhanced GOx-like activity of BPQDs under NIR irradiation was capable of catalytical generating massive toxic reactive oxygen species via using cellular glucose.By combining the intrinsic photothermal property and the unique photothermal-enhanced GOx-like catalytic activity,the developed BPQDs were demonstrated to be an effective therapeutic strategy for inhibiting tumor growth in vivo.We believe that this work will provide a novel perspective for the development of nanozymes in tumor catalytic therapy. | Hui Ding Daji Wang Haibing Huang Xiaozhu Chen Jie Wang Jinjie Sun Jianlin Zhang Lu Lu Beiping Miao Yanjuan Cai Kelong Fan Yongtian Lu Hongsong Dong Xiyun Yan Guohui Nie Minmin Liang | 2022 | Nano Research2022，15，2： | 1 |
| 10 | Recent progress in carbon-dots-based nanozymes for chemosensing and biomedical applications显示文摘Nanozymes are nanomaterials with enzyme-like activities that efficiently overcome the drawbacks of natural enzymes in biosensing,detection,and biomedical fields,and they are the most widely used artificial enzymes.Owing to their excellent catalytic characteristics,biocompatibility,and environmental favorability,carbondots-based(CDs) nanozymes have inspired a research upsurge.However,no review focusing on CDs nanozymes has been published,even though substantial advances have been achieved.Herein,the advances,catalytic activities,and applications of CDs nanozymes are highlighted and summarized.In addition,the critical issues and challenges of researching nanozymes are discussed.We hope that this review will broaden the horizons of nanozymes and CDs nanozymes,as well as promote their development. | Deming He Minmin Yan Pengjuan Sun Yuanqiang Sun Lingbo Qu Zhaohui Li | 2021 | Chinese Chemical Letters2021，32，10： | 1 |
| 11 | Microstructure and Corrosion Properties of Duplex-Structured Extruded Mg-6Li-4Zn-xMn Alloys显示文摘The extruded Mg-6 Li-4 Zn-xMn(x=0,0.4,0.8,1.2 wt%)alloys were prepared,and the microstructure of the test alloys was investigated by optical microscopy,scanning electron microscopy and transmission electron microscopy.The corrosion properties were determined by electrochemical measurements and immersion measurements in 3.5%NaCl solution.The results indicate that the extruded Mg-6 Li-4 Zn-xMn alloys are mainly composed ofα-Mg phase,β-Li phase,Mn precipitates and some intermetallic compounds(MgLi_(2)Zn).With the addition of Mn,stable corrosion products were formed on the surface of the test alloy,which can effectively inhibit further corrosion progress and improve the corrosion resistance.Mg-6 Li-4 Zn-1.2 Mn alloy exhibits the best corrosion resistance,attributed to grain refinement,the improvement of the stability of corrosion product film and uniform distribution of fine second phases. | Minmin Li Zhe Qin Yan Yang Xiaoming Xiong Gang Zhou Xiaofei Cui Bin Jiang Xiaodong Peng Fusheng Pan | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，5： | 1 |

| 15 | QTL Mapping for Plant Height of Wheat under Different Irrigation Modes显示文摘In order to mine gene loci associated with drought resistance and water use efficiency,and provide guidance for the breeding of drought-resistant wheat varieties,quantitative trait loci(QTLs)for plant height(PH)and stem height(SH)of wheat were evaluated using a population of 302 recombinant inbred lines(RILs)derived from a cross between drought-tolerant cultivar Luohan 2 and water-sensitive cultivar Weimai 8 under different water regimes in six environments.Totally 17 additive QTLs for PH and SH were identified and distributed on chromosomes 2B,3A,3B,4A,5A,5D,6B,7A and 7B,respectively,which explained3.3%to 26.95%phenotypic variations,with additive effect of 1.919 6 to 5.382 8 cm.Among them,14 QTLs,24 times and 5 QTLs,7 times were detected in three irrigation environments and three drought stress environments,respectively.Both the number of QTLs for PH and the times detected in drought stress environments were significantly less than those in irrigation environments.Of all the 17 QTLs for PH,12 were detected only in irrigation environment,three QTLs were detected only in drought stress environment,and two QTLs were detected in both environments,suggesting that the expression of the genes is greatly influenced by environmental condition.QPh-WL-7A.3 detected between maker Xbarc049 and Xgwm273 on chromosome 7A in all the three drought stress environments,can enhance2.481 5-3.697 2 cm of PH,explain 8.6%-10.0%additive effect,so it is useful for the genetic improvement of drought tolerance and molecular marker-assisted selection in wheat. | Yanyun REN Ling HUANG Minmin SHAO Leiming SUN Kai ZHAO Jinping WANG Xingke XU Weiying FENG Jifeng WANG Lu YAN Shichong WANG Lin WANG | 2017 | Agricultural Biotechnology2017，6，4： | 0 |
| 16 | Highly sensitive nanozyme strip:An effective tool for forensic material evidence identification显示文摘During criminal case investigations,blood evidence tracing is critical for criminal investigation.However,the blood stains are often cleaned or covered up after the crime,resulting in trace residue and difficult tracking.Therefore,a highly sensitive and specific method for the rapid detection of human blood stains remains urgent.To solve this problem,we established a nanozyme-based strip for rapid detection of blood evidence with high sensitivity and specificity.To construct reliable nanozyme strips,we synthesized CoFe_(2)O_(4) nanozymes with high peroxidase-like activity by scaling up to gram level,which can be supplied for six million tests,and conjugated antibody as a detection probe in nanozyme strip.The developed CoFe_(2)O_(4) nanozyme strip can detect human hemoglobin(HGB)at a concentration as low as 1 ng/mL,which is 100 times lower than the commercially available colloidal gold strips(100 ng/mL).Moreover,this CoFe_(2)O_(4) nanozyme strip showed high generality on 12 substrates and high specificity to human HGB among 13 animal blood samples.Finally,we applied the developed CoFe_(2)O_(4) nanozyme strip to successfully detect blood stains in three real cases,where the current commercial colloidal gold strip failed to do.The results suggest that the CoFe_(2)O_(4) nanozyme strip can be used as an effective on-scene detection method for human blood stains,and can further be used as a long-term preserved material evidence for traceability inquiry. | Juanji Hong Zhanjun Guo Dihan Duan Yi Zhang Xin Chen Yongjiu Li Zheng Tu Lei Feng Lei Chen Xiyun Yan Lizeng Gao Minmin Liang Demin Duan | 2024 | Nano Research2024，17，3： | 0 |
| 17 | Ultrafast synthetic strategies under extreme heating conditions toward single-atom catalysts显示文摘Dispersing atomic metals on substrates provides an ideal method to maximize metal utilization efficiency, which is important for the production of cost-effective catalysts and the atomic-level control of the electronic structure. However, due to the high surface energy, individual single atoms tend to migrate and aggregate into nanoparticles during preparation and catalytic operation. In the past few years, various synthetic strategies based on ultrafast thermal activation toward the effective preparation of single-atom catalysts(SACs) have emerged, which could effectively solve the aggregation issue. Here, we highlight and summarize the latest developments in various ultrafast synthetic strategy with rapid energy input by heating shockwave and instant quenching for the synthesis of SACs, including Joule heating, microwave heating, solid-phase laser irradiation, flame-assisted method, arc-discharge method and so on,with special emphasis on how to achieve the uniform dispersion of single metal atoms at high metal loadings as well as the suitability for scalable production. Finally, we point out the advantages and disadvantages of the ultrafast heating strategies as well as the trends and challenges of future developments. | Guanchao He Minmin Yan Haisheng Gong Huilong Fei Shuangyin Wang | 2022 | International Journal of Extreme Manufacturing2022，4，3： | 0 |

| 19 | Molecular Characterization, Expression Pattern and Transcriptional Regulation of Figla During Gonad Development in Japanese Founder (Paralichthys olivaceus)显示文摘The factor in the germline alpha(figla), as a member of the basic helix-loop-helix family, has been reported to be involved in ovary development in mammals and teleosts. However, the regulatory mechanisms of figla in teleosts remain unclear. Here,figla in P. olivaceus(Pofigla) was characterized with encoding a 202 amino acid protein that contains a conserved basic region and helix-loop-helix(HLH) domain. Amino acids alignment and synteny analysis revealed that Pofigla was conserved with the orthologous gene sequences in other vertebrates. The results of qRT-PCR showed Pofigla was maternally inherited during embryonic development. For tissue distribution, Pofigla showed a sexually dimorphic gene expression in the gonad of different genders, with a higher expression in ovary than in testis. In situ hybridization(ISH) results demonstrated Pofigla was specifically expressed in germ cells including oocytes, spermatogonia and spermatocytes. By screening and analyzing two proximal regions(-2966/-2126 and-772/-444) with high promoter activity, we found SOX5, LEF1, FOXP1 and GATA1 may play important roles in the transcriptional regulation of Pofigla. Furthermore, we observed the co-localization between Figla and LEF1 in HEK 293T cells. And the significant up-regulation effect of the canonical Wnt signaling pathway on the expression of Pofigla was found in cultured ovarian cells. This study provided the first evidence that figla not only has an important function in ovary development, but also plays some potential roles in testis development and/or male germ cell differentiation during early testis development in P. olivaceus. The results provide valuable reference in exploring the regulatory network of figla in teleost. | QU Jiangbo LI Rui LIU Yuxiang SUN Minmin YAN Weijie LIU Jinxiang WANG Xubo ZHANG Quanqi | 2022 | Journal of Ocean University of China2022，21，4： | 0 |
| 20 | The effect of laser acupuncture on hypoxia tolerance and inflammation reaction in mice with optical fiber acupuncture needle intra body显示文摘Hypoxia is a disorder in which the tissues are not oxygenated adequately.The lack of oxygen may cause irreversible damage to the major organs such as the brain,heart and lungs.In severe cases,coma,seizures,and death may happen.In addition to the routine medication,acupuncture.treatment has been applied as a complementary treatment to counter hypoxia.In this paper,the optical fiber acupuncture needle was fabricated using the optical fiber imbedding into the metal capillary tube with needle tip,therefore made it easy to insert into the body for the laser treatment.The laser optical fiber needle treatment to the ST36 acupoint conducted with the laser.irradiation intra body.The normobaric hypoxia tolerance test results in mice show that the optical fber needle treatment to the ST36 acupoint with laser acupuncture appears to improve the tolerance to hypoxia.The mice treated with laser acupuncture expressed high level of IL-1βin serum.Our results suggest that laser optical fiber needle acupuncture may serve as a potential treatment for hypoxia. | Shupeng Liu Minmin Xu Xiumei Cao Junyi Hou Na Chen Fufei Pang Zhenyi Chen Xiangfei Yang Tingyun Wang Jianshe Yan | 2017 | Journal of Innovative Optical Health Sciences2017，，2： | 0 |
