| 1 | miR-23b promotes cutaneous wound healing through inhibition of the inflammatory responses by targeting ASK1显示文摘Wound healing is a complicated event that develops in three overlapping phases:inflammatory, proliferative,and remodeling.MicroRNAs (miRNAs)have been proved to play an important role in the healing process of skin trauma,and alteration of specific miRNA expression during different phases may be associated with abnormal wound healing.In this study,we determined the variation of miR-23b expression after trauma in normal mice and in cultured cells exposed to lipopolysaccharide.We further demonstrated that excessive miR-23b could significantly accelerate wound healing in vivo.Up-regulation of miR-23b decreases infiltration of inflammatory cells,as evidenced by pathologic staining.Meanwhile,miR-23b could significantly inhibit the expression of pro-inflammatory cytokines,including TNF-α,IL-1β,IL-6,and Ccl2,and significantly increase antiinflammatory factor IL-10.Furthermore,miR-23b could also promote α-SMA expression in a fiber pattern and increase the expression of Col1a1 and Col3a1.Importantly,we also showed that miR- 23b could inhibit inflammation to promote wound healing by targeting apoptotic signal-regulating kinase 1 (ASK1).Notably,knockdown of ASK1 could reduce inflammation factor expression in vitro.Together,our data reveal that miR-23b is a potent therapeutic agent for cutaneous wound healing that shortens the period of inflammatory responses and promotes keratinocyte migration for the re-epithelialization of wound sites. | Hongzhi Li Xiao Han Kuiyang Zuo Li Li Jieting Liu Xiaohuan Yuan Yongchao Shen Minglong Shao Daxin Pang Yanhui Chu Binghai Zhao | 2018 | Acta Biochimica et Biophysica Sinica2018，50，11： | 5 |
| 2 | Thermal Growth and Nanomagnetism of the Quasi-one Dimensional Iron Oxide显示文摘Quasi-one dimensional iron oxide nanowires with flat needle shape were synthesized on the iron powders by a rather simple catalyst-free thermal oxidation process in ambient atmosphere. The characterization by field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Raman and high-resolution transmission electron microscopy (HRTEM) revealed that these nanostructures are single crystalline α-Fe2O3. The various dimensions with 40-170 nm in width and 1-8 μm in length were obtained by tuning the growth temperature from 280 to 480℃. A surface diffusion mechanism was proposed to account for the growth of quasi-one dimensional nanostructure. The typical α-Fe2O3 nanowires synthesized at 430℃ had a reduced Morin temperature TM of 131 K in comparison with their bulk counterpart. The coercivitis Hc of these nanowires are 321 and 65 Oe at 5 and 300 K, respectively. The temperature of synthesis also has important effects on the magnetic properties of these nanowires. | Minglong Zhong Zhongwu Liu Xichun Zhong Hongya Yu Dechang Zeng | 2011 | Journal of Materials Science & Technology2011，27，11： | 5 |
| 3 | Effect of burden and origin sites of premature ventricular contractions on left ventricular function by 7-day Holter monitor显示文摘Recent studies have shown that premature ventricular contractions(PVCs) could enlarge the heart,but its risk factors are incompletely understood as a single 24-hour recording cannot reflect the true PVC burden due to day-to-day variability.Our purpose was to investigate the effect of burden and origin sites on left ventricular(LV) function in patients with PVCs by 7-day Holter electrocardiography(ECG).From May 2012 to August2013,112 consecutive patients with PVCs were recruited from the authors' affiliated hospital.All patients received2-dimensional transthoracic echocardiography,12-lead routing ECG and 7-days Holter ECG.Serum N-terminal probrain natriuretic peptide(NT-proBNP) levels were measured.A total of 102 participants with PVCs were included in the final analysis.Origin of PVCs from the tricuspid annulus had the highest burden and NT-proBNP level.LV papillary muscle had a higher LV ejection fraction(EF) level and a lower LV end-systolic dimension(ESD) than other PVC foci(P<0.05).The high burden group had a higher LV end-diastolic dimension(EDD) and LVESD but lower LVEF than the other two groups(P<0.05).Female,older age,physical work,and history of PVCs had a significantly positive correlation with symptoms.Male,older age,physical work,and high burden were positive predictors of enlarged LVEDD,LVESD and higher serum NT-proBNP level,but lower LVEF.Seven-day dynamic ECG Holter monitor showed the true PVC burden on patients with PVCs.PVCs with a lower burden or origin from the LV papillary muscle and the fascicle were relatively benign,while PVCs with a higher burden or origin from the tricuspid annulus may lead to cardiac dysfunction. | Wenhua Xu Mingfang Li Minglong Chen Bing Yang Daowu Wang Xiangqing Kong Hongwu Chen Weizhu Ju Kai Gu Kejiang Cao Hailei Liu Qi Jiang Jiaojiao Shi Yan Cui Hong Wang | 2015 | The Journal of Biomedical Research2015，29，6： | 4 |
| 4 | Ni/Pd-based ohmic contacts to p-GaN through p-InGaN/p^(+)-GaN contacting layers显示文摘Specific contact resistance to p-GaN was measured for various structures of Ni/Pd-based metals and thin(20-30 nm thick)p-InGaN/p^(+)-GaN contacting layers.The effects of surface chemical treatment and annealing temperature were ex-amined.The optimal annealing temperature was determined to be 550°C,above which the sheet resistance of the samples de-graded considerably,suggesting that undesirable alloying had occurred.Pd-containing metal showed~35%lower com-pared to that of single Ni.Very thin(2-3.5 nm thick)p-InGaN contacting layers grown on 20-25 nm thick p^(+)-GaN layers exhib-ited one to two orders of magnitude smaller values of compared to that of p^(+)-GaN without p-InGaN.The current density de-pendence of,which is indicative of nonlinearity in current-voltage relation,was also examined.The lowest achieved through this study was 4.9×10^(-5)Ω·cm^(2)@J=3.4 kA/cm^(2). | Minglong Zhang Masao Ikeda Siyi Huang Jianping Liu Jianjun Zhu Shuming Zhang Hui Yang | 2022 | Journal of Semiconductors2022，43，9： | 3 |
| 5 | Methylesterification of cell-wall pectin controls the diurnal flower-opening times in rice显示文摘Flowers are the core reproductive organ of plants, and flowering is essential for cross-pollination. Diurnal flower-opening time is thus a key trait influencing reproductive isolation, hybrid breeding, and thermostability in plants. However, the molecular mechanisms controlling this trait remain unknown. Here, we report that rice Diurnal Flower Opening Time 1 (DFOT1) modulates pectin methylesterase (PME) activity to regulate pectin methylesterification levels of the lodicule cell walls, which affect lodicule swelling to control diurnal flower-opening time. DFOT1 is specifically expressed in the lodicules, and its expression gradually increases with the approach to flowering but decreases with flowering. Importantly, a knockout of DFOT1 showed earlier diurnal flower opening. We demonstrate that DFOT1 interacts directly with multiple PMEs to promote their activity. Knockout of PME40 also resulted in early diurnal flower opening, whereas overexpression of PME42 delayed diurnal flower opening. Lower PME activity was observed to be associated with higher levels of pectin methylesterification and the softening of cell walls in lodicules, which contribute to the absorption of water by lodicules and cause them to swell, thus promoting early diurnal flower opening. Higher PME activity had the opposite effect. Collectively, our work uncovers a molecular mechanism underlying the regulation of diurnal flower-opening time in rice, which would help reduce the costs of hybrid breeding and improve the heat tolerance of flowering plants by avoiding higher temperatures at anthesis. | Mumei Wang Xiaopei Zhu Guoqing Peng Minglong Liu Shuqing Zhang Minghao Chen Shitang Liao Xiaoying Wei Peng Xu Xiyu Tan Fangping Li Zhichuan Li Li Deng Ziliang Luo Liya Zhu Shuai Zhao Dagang Jiang Jing Li Zhenlan Liu Xianrong Xie Shaokui Wang Aimin Wu Chuxiong Zhuang Hai Zhou | 2022 | Molecular Plant2022，15，6： | 2 |
| 6 | Multiscale analysis of the contents of palmatine in the Nature populations of Phellodendron amurense in Northeast China显示文摘Palmatine is a valuable ingredient in Chinese medicine that is produced by Phellodendron amurense Rupr.The contents of palmatine content in root bark, trunk bark,perennial branch bark, annual branches, and leaves of the trees with different ages and geographies in Northeast China were measured by high-performance liquid chromatography.The contents of palmatine in the barks of root, trunk, and perennial branch were significantly higher than those in annual branches and leaves. The contents of palmatine in trunk bark and root bark from Lesser Khingan Mountains increased with age, which is significantly opposite to other three vegetation types. The contents of palmatine in perennial branch bark, annual bark and leaves had no significant regularity. Moreover, the contents of palmatine in samples of root bark, trunk bark, perennial branch bark and annual bark varied significantly with latitude. The nature populations of P. amurense growing at low latitude contained significantly more palmatine than those growing at high latitude. These results provide a scientific basis for the reasonable cultivation and efficient utilization of P. amurense. | Minglong Sun Lijiao Xu Yingli Peng Tong Liu Yuhong Zhang Zhiqiang Zhou | 2016 | Journal of Forestry Research2016，27，2： | 2 |
| 7 | Rapid and accurate detection of African swine fever virus by DNA endonuclease-targeted CRISPR trans reporter assay显示文摘The first case of African swine fever(ASF)outbreak in China was reported in a suburban pig farm in Shenyang in 2018.Since then,the rapid spread and extension of ASF has become the most serious threat fo r the swine industry.Therefore,rapid and accurate detection of African swine fever virus(ASFV)is essential to provide effective strategies to control the disease.In this study,we developed a rapid and accurate ASFV-detection method based on the DNA endonuclease-targeted CRISPR trans reporter(DETECTR)assay.By com bining recombinase polymerase am plification w ith CRISPR-Cas12a proteins,the DETECTR assay dem onstrated a m inim um detection lim it of eight copies with no cross reactivity with other swine viruses.Clinical blood samples were detected by DETECTR assay and showed 100%(30/30)agreement w ith real-tim e polymerase chain reaction assay.The rapid and accurate detection of ASFV may facilitate tim ely eradication measures and strict sanitary procedures to control and prevent the spread of ASF. | Zongjie Li Jianchao Wei Di Di Xin Wang Chenxi Li Beibei Li Yafeng Qiu Ke Liu Feng Gu Minglong Tong Shuiming Wang Xiaodong Wu Zhiyong Ma | 2020 | Acta Biochimica et Biophysica Sinica2020，52，12： | 2 |
| 8 | Suitable contacting scheme for evaluating electrical properties of GaN-based p-type layers显示文摘A suitable contacting scheme for p-(Al)GaN facilitating quick feedback and accurate measurements is proposed in this study.22 nm p^(+)-GaN followed by 2 nm p-In_(0.2)Ga_(0.8)N was grown on p-type layers by metal-organic chemical vapor deposition.Samples were then cut into squares after annealing and contact electrodes using In balls were put at the corners of the squares.Good linearity between all the electrodes was confirmed inⅠ–Ⅴcurves during Hall measurements even with In metal.Serval samples taken from the same wafer showed small standard deviation of~4%for resistivity,Hall mobility and hole concentration.The influence of contact layer on the electrical characteristics of bulk p-type layers was then investigated by step etching technique using inductively coupled plasma etching and subsequent Hall-effect measurements.Identical values could be obtained consistently when a 28 nm non-conductive layer thickness at the surface was taken into account.Therefore,the procedures for evaluating the electrical properties of GaN-based p-type layers just using In balls proposed in this study are shown to be quick and useful as for the other conventionalⅢ–Ⅴmaterials. | Siyi Huang Masao Ikeda Minglong Zhang Jianjun Zhu Jianping Liu | 2023 | Journal of Semiconductors2023，44，5： | 1 |
| 9 | A wearable real-time telemonitoring electrocardiogram device compared with traditional Holter monitoring显示文摘Arrhythmias are very common in the healthy populations as well as patients with cardiovascular diseases.Among them,atrial fibrillation(AF)and malignant ventricular arrhythmias are usually associated with some clinical events.Early diagnosis of arrhythmias,particularly AF and ventricular arrhythmias,is very important for the treatment and prognosis of patients.Holter is a gold standard commonly recommended for noninvasive detection of paroxysmal arrhythmia.However,it has some shortcomings such as fixed detection timings,delayed report and inability of remote real-time detection.To deal with such problems,we designed and applied a new wearable 72-hour triple-lead H3-electrocardiogram(ECG)device with a remote cloud-based ECG platform and an expertsupporting system.In this study,31 patients were recruited and 24-hour synchronous ECG data by H3-ECG and Holter were recorded.In the H3-ECG group,ECG signals were transmitted using remote real-time modes,and confirmed reports were made by doctors in the remote expert-supporting system,while the traditional modes and detection systems were used in the Holter group.The results showed no significant differences between the two groups in 24-hour total heart rate(HR),averaged HR,maximum HR,minimum HR,premature atrial complexes(PACs)and premature ventricular complexes(PVCs)(P>0.05).The sensitivity and specificity of capture and remote automatic cardiac events detection of PACs,PVCs,and AF by H3-ECG were 93%and 99%,98%and 99%,94%and 98%,respectively.Therefore,the long-term limb triple-lead H3-ECG device can be utilized for domiciliary ECG self-monitoring and remote management of patients with common arrhythmia under medical supervision. | Qin Shen Jianqing Li Chang Cui Xingyao Wang Hongxiang Gao Chengyu Liu Minglong Chen | 2021 | The Journal of Biomedical Research2021，35，3： | 1 |

| 12 | Transport signatures of the topological surface state induced by the size effect in superconductor β-PdBi_(2)显示文摘The superconductivity and nontrivial topological electronic state are key hallmarks of topological superconductors.Here,we focus on the transport signals of possible topological surface state in the topological superconductor candidate β-PdBi_(2) nanoflake with a thickness of 21 nm.The resistance demonstrates a semiconductor-metal transition followed by an upturned behavior as the temperature decreases.A large and unsaturated longitudinal magnetoresistance(MR),accompanied by distinct Shubnikov-de Hass oscillation in Hall resistance,is observed.An analysis of Hall resistance reveals that the carriers present the characteristics of relativistic particles with small effective mass and extremely high mobility.The angle-dependent quantum oscillations demonstrate a two-dimensional Fermi surface topology.A giant anisotropic MR as large as 98%is detected when rotating the magnetic field.These results provide the possible transport signals of a nontrivial topological electronic state,establishing a further understanding of the topological properties of the low-dimensional topological superconductor candidate β-PdBi_(2). | Ankang Zhu Zheng Chen Yuyan Han Mengcheng Zhu Huanhuan Wang Minglong Han Liang Li Xue Liu Guolin Zheng Xiangde Zhu Wenshuai Gao Mingliang Tian | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，7： | 0 |
| 13 | A New Dynamics Analysis Model for Five-Axis Machining of Curved Surface Based on Dimension Reduction and Mapping显示文摘The equipment used in various fields contains an increasing number of parts with curved surfaces of increasing size.Five-axis computer numerical control(CNC)milling is the main parts machining method,while dynamics analysis has always been a research hotspot.The cutting conditions determined by the cutter axis,tool path,and workpiece geometry are complex and changeable,which has made dynamics research a major challenge.For this reason,this paper introduces the innovative idea of applying dimension reduction and mapping to the five-axis machining of curved surfaces,and proposes an efficient dynamics analysis model.To simplify the research object,the cutter position points along the tool path were discretized into inclined plane five-axis machining.The cutter dip angle and feed deflection angle were used to define the spatial position relationship in five-axis machining.These were then taken as the new base variables to construct an abstract two-dimensional space and establish the mapping relationship between the cutter position point and space point sets to further simplify the dimensions of the research object.Based on the in-cut cutting edge solved by the space limitation method,the dynamics of the inclined plane five-axis machining unit were studied,and the results were uniformly stored in the abstract space to produce a database.Finally,the prediction of the milling force and vibration state along the tool path became a data extraction process that significantly improved efficiency.Two experiments were also conducted which proved the accuracy and efficiency of the proposed dynamics analysis model.This study has great potential for the online synchronization of intelligent machining of large surfaces. | Minglong Guo Zhaocheng Wei Minjie Wang Zhiwei Zhao Shengxian Liu | 2023 | Chinese Journal of Mechanical Engineering2023，36，6： | 0 |
| 14 | Selective photocatalytic aerobic oxidative cleavage of lignin C–O bonds over sodium lignosulfonate modified Fe_(3)O_(4)/TiO_(2)显示文摘Lignocellulose shows significantly potential in sustainable conversion to high-quality fuel and valueadded chemicals with the demands for realizing the rapid cycle of carbon resources and helping to reach carbon neutrality in nature.Selective tailoring of α-O-4,β-O-4,etc.linkages in lignin has always been viewed as 'death blow' for its depolymerization.Herein,novel sodium lignosulfonate(SL) modified Fe_(3)O_(4)/TiO_(2)(SL-Fe_(3)O_(4)/TiO_(2)) spherical particles have been developed and used as catalysts for selectively photocatalytic oxidative cleavage of organosolv lignin.As expected,80% selective conversion of lignin in C2-C4 esters has been achieved,while C-O bonds in lignin model compounds can be effectively cleaved.Other than normal hydroxyl radical-mediated photocatalytic depolymerization of lignin over TiO_(2)-based materials,in this contribution,mechanism studies indicate that photogenerated holes and superoxide anion radicals are main active species,which trigger the cleavage of α/β-O-4 bond,and the isotopelabeling study confirms the crucial factor of C_β-H dehydrogenation in cleavage of β-O-4 bonds. | Kejia Wu Jinrong Liang Sijie Liu Yimin Huang Minglong Cao Qiang Zeng Xuehui Li | 2023 | Journal of Energy Chemistry2023，，9： | 0 |
| 15 | Development of a micro-indentation device for measuring the mechanical properties of soft materials显示文摘Indentation is a simple and nondestructive method to measure the mechanical properties of soft materials,such as hydrogels,elastomers and soft tissues.In this work,we have developed a micro-indentation system with high-precision to measure the mechanical properties of soft materials,where the shear modulus and Poisson’s ratio of the materials can be obtained by analyzing the load–relaxation curve.We have validated the accuracy and stability of the system by comparing the measured mechanical properties of a polyethylene glycol sample with that obtained from a commercial instrument.The mechanical properties of another typical polydimethylsiloxane sample submerged in heptane are measured by using conical and spherical indenters,respectively.The measured values of shear modulus and Poisson’s ratio are within a reasonable range. | Xiang He Pengfei Wang Guoyou Huang Shaobao Liu Minglong Xu Feng Xu TianJian Lu | 2013 | Theoretical & Applied Mechanics Letters2013，3，5： | 0 |
| 16 | Superbroad-band actively tunable acoustic metamaterials driven from poly(ethylene terephthalate)/carbon nanotube nanocomposite membranes显示文摘Actively tunable acoustic metamaterials have attracted ever increasing attention.However,their tunable frequency range is quite narrow(tens of Hz)even under ultrahigh applied voltage(about 1,000 V).Here,we report a superbroad-band actively tunable acoustic metamaterials with the bandwidth over 400 Hz under a low voltage.In the actively tunable acoustic metamaterials,the acoustic membrane is a laminated nanocomposite consisting of a poly(ethylene terephthalate)(PET)and super-aligned carbon nanotube(CNT)drawn from CN T forest array.The laminated nanocomposite membrane exhibits adjustable acoustic properties,whose modulus can be adjusted by applying external electric field.The maximum frequency bandwidth of PET/CN T nanocomposite membrane reaches 419 Hz when applying an external DC voltage of 60 V.Our actively tunable acoustic metamaterials with superbroad-band and lightweight show very promising foreground in noise reduction applications. | Ying Li Wen Ning Qingyu Peng Minglong Yang Dongyi Lei Siyao Guo Peng Liu Kaili Jiang Xiaodong He Yibin Li | 2021 | Nano Research2021，14，1： | 0 |
| 17 | The E3 ubiquitin ligase CSIT1 regulates critical sterility-inducing temperature by ribosome-associated quality control to safeguard two-line hybrid breeding in rice显示文摘Two-line hybrid breeding can fully utilize heterosis in crops.In thermo-sensitive genic male sterile(TGMS)lines,low critical sterility-inducing temperature(CSIT)is vital to safeguard the production of two-line hybrid seeds in rice(Oryza sativa),but the molecular mechanism determining CSIT is unclear.Here,we report the cloning of CSIT1,which encodes an E3 ubiquitin ligase,and show that CSIT1 modulates the CSIT of thermo-sensitive genic male sterility 5(tms5)-based TGMS lines through ribosome-associated quality control(RQC).Biochemical assays demonstrated that CSIT1 binds to the 80S ribosomes and ubiquitinates abnormal nascent polypeptides for degradation in the RQC process.Loss of CSIT1 function inhibits the possible damage of tms5 to the ubiquitination system and protein translation,resulting in enhanced accumulation of anther-related proteins such as catalase to suppress abnormal accumulation of reactive oxygen species and premature programmed cell death in the tapetum,thereby leading to a much higher CSIT in the tms5-based TGMS lines.Taken together,our findings reveal a regulatory mechanism of CSIT,providing new insights into RQC and potential targets for future two-line hybrid breeding. | Guoqing Peng Minglong Liu Liya Zhu Wenlong Luo Qinghua Wang Mumei Wang Huiqiong Chen Ziliang Luo Yueping Xiao Yongjie Zhang Haona Hong Zhenlan Liu Lingyan Zhou Guoqiang Guo Yingxiang Wang Chuxiong Zhuang Hai Zhou | 2023 | Molecular Plant2023，16，10： | 0 |
| 18 | Epicardial adipose tissue around the superior vena cava: A single center study of factors related to atrial fibrillation显示文摘The superior vena cava(SVC)is the main component of non-pulmonary vein(PV)ectopy in patients with atrial fibrillation(AF).Researchers have found that epicardial adipose tissue(EAT)volume is related to the AF substrate,which can be defined by the low voltage area(LVA).This study aimed to investigate the relationship between SVC-EAT and SVC-AF.Twenty-six patients with SVC-AF triggers were identified as the SVC-AF group.Other three groups were defined and included as the LVA-AF group(LVA>5%),non-LVA-AF group(LVA<5%),and physical examination(PE)group.EAT around left atrium(LA-EAT)and SVC-EAT volumes were obtained using a cardiac risk assessment module.According to the SVC/LA-EAT ratio,there are significant differences between the SVC-AF group and the three control groups(the SVC-AF group 0.092±0.041 vs.the LVA-AF group 0.054±0.026,the non-LVA-AF group 0.052±0.022,and the PE group 0.052±0.019,all P<0.001).Receiver operating characteristic curve analysis suggests the optimal cut-off point of SVC/LA-EAT ratio is 6.8%for detecting SVC-AF patients,with 81.1%sensitivity,73.1%specificity,and an area under the curve of 0.83(95%confidence interval,0.75-0.91).Those with SVC-AF have a higher SVC/LA-EAT ratio and empirical SVC isolation could be considered if the SVC/LA-EAT ratio was over 6.8%. | Xingxing Sun Jun Wang Qing Yan Weizhu Ju Fengxiang Zhang Gang Yang Kai Gu Hailei Liu Zidun wang Xiaohong Jiang Mingfang Li Di Xu Yi Xu Hongwu Chen Minglong Chen | 2022 | The Journal of Biomedical Research2022，36，6： | 0 |

| 20 | Microstructure, mechanical properties and magnetic properties of FeCoNiCuTiSi_x high-entropy alloys显示文摘The microstructure, mechanical properties and magnetic properties of FeCoNiCuTiSi_x(x=0, 0.05, 0.1, 0.2, 0.4 and 0.5) highentropy alloys were studied in detail in the present paper. The crystal structure changes from FCC+Laves to FCC+BCC+Laves phases, as the Si content increases. Cu is more segregated with the increase in Si content, which can be explained from a thermodynamic point of view. The FeCoNiCuTi high-entropy alloy has good compression mechanical properties, and the fracture strength, fracture strain, and Vickers hardness are 1584.2 MPa, 3.3% and 483.2 HV, respectively. However, the plasticity of the alloy decreases slightly as the Si content increases. The highest fracture strength obtained in this study is 1841.7 MPa at x=0.1. | QU HuaiZhi GONG MingLong LIU FengFang GAO BingYu BAI Jing GAO QiuZhi LI Song | 2020 | Science China(Technological Sciences)2020，63，3： | 0 |
