1Age-related macular degeneration: Epidemiology, genetics, pathophysiology, diagnosis, and targeted therapy显示文摘Age-related macular degeneration (AMD) is a complex eye disorder and is the leading cause of incurable blindness worldwide in the elderly. Clinically, AMD initially affects the central area of retina known as the macula and it is classified as early stage to late stage (advanced AMD). The advanced AMD is classified into the nonexudative or atrophic form (dry AMD) and the exudative or neovascular form (wet AMD). More severe vision loss is typically associated with the wet form. Multiple genetic factors, lipid metabolism, oxidative stress and aging, play a role in the etiology of AMD. Dysregulation in genetic to AMD is established to 46%–71% of disease contribution, with CFH and ARMS2/HTRA1 to be the two most notable risk loci among the 103 identified AMD associated loci so far. Chronic cigarette smoking is the most proven consistently risk living habits for AMD. Deep learning algorithm has been developed based on image recognition to distinguish wet AMD and normal macula with high accuracy. Currently, anti-vascular endothelial growth factor (VEGF) therapy is highly effective at treating wet AMD. Several new generation AMD drugs and iPSC-derived RPE cell therapy are in the clinical trial stage and are promising to improve AMD treatment in the near future.Yanhui Deng Lifeng Qiao Mingyan Du Chao Qu Ling Wan Jie Li Lulin Huang 2022Genes & Diseases2022,9,1:17
2Face recognition system based on CNN and LBP features for classifier optimization and fusion显示文摘Face recognition has been a hot-topic in the field of pattern recognition where feature extraction and classification play an important role. However,convolutional neural network( CNN) and local binary pattern( LBP) can only extract single features of facial images,and fail to select the optimal classifier. To deal with the problem of classifier parameter optimization,two structures based on the support vector machine( SVM) optimized by artificial bee colony( ABC) algorithm are proposed to classify CNN and LBP features separately. In order to solve the single feature problem,a fusion system based on CNN and LBP features is proposed. The facial features can be better represented by extracting and fusing the global and local information of face images. We achieve the goal by fusing the outputs of feature classifiers. Explicit experimental results on Olivetti Research Laboratory( ORL) and face recognition technology( FERET) databases show the superiority of the proposed approaches.Wu Yulin Jiang Mingyan 2018The Journal of China Universities of Posts and Telecommunications2018,25,1:10
3MicroRNA in vivo precipitation identifies miR-151-3p as a computational unpredictable miRNA to target Stat3 and inhibits innate IL-6 production显示文摘MicroRNAs(miRNAs)function as important regulators in the immune response and inflammation.Several approaches have been reported to computationally predict miRNAs and their potential targets.However,there are still many miRNA–target interactions that are unpredictable by using the current computational algorithms.We established a miRNA in vivo precipitation method(miRIP)to identify unpredictable miRNAs with definite targets in these cells.Because Stat3 is a well-known transcription factor involved in innate immunity and inflammation,we utilized the miRIP method to identify miRNAs that bind Stat3 mRNA in macrophages.Among the captured miRNAs,miR-151-3p was confirmed to interact with Stat3 mRNA 3′-UTR and downregulate the Stat3 protein levels.LPS stimulation decreased miR-151-3p expression,thereby increasing IL-6 production.Therefore,we found that miR-151-3p inhibited LPS-induced IL-6 production by targeting Stat3.These data further confirmed miRIP as an efficient method to identify unpredictable miRNAs and explore miRNAs-mediated regulation in innate immunity and inflammation.Xiang Liu Xiaoping Su Sheng Xu Huamin Wang Dan Han Jiangxue Li Mingyan Huang Xuetao Cao 2018Cellular & Molecular Immunology2018,15,2:8
4High-performance Zn battery with transition metal ions co-regulated electrolytic MnO_(2)显示文摘Electrolytic MnO_(2)/Zn batteries have attracted extensive attention for use in large-scale energy storage applications due to their low cost,high output voltage,safety,and environmental friendliness.However,the poor electrical conductivity of MnO_(2)limits its deposition and dissolution at large capacities,which leads to sluggish reaction kinetics and drastic capacity decay.Here,we report a theory-guided design principle for an electrolytic MnO_(2)/Zn battery co-regulated with transition metal ions that has improved electrochemical performance in terms of deposition and stripping chemistries.We start with first-principles calculations to predict the electrolytic effects of regulating transition metal ions in the deposition/stripping chemistry of the MnO_(2)cathode.The results indicate that with the simultaneous incorporation of strongly electronegative Co and Ni,the MnO_(2)cathode tends to possess more active electron states,faster charge-transfer kinetics,and better electrical conductivity than either MnO_(2)regulated with Co or Ni on their own,or pristine MnO_(2);hence,this co-regulation is beneficial for the cathode solid/liquid MnO_(2)/Mn2t reactions.We then fabricate and demonstrate a novel Co2t and Ni2t coregulated MnO_(2)/Zn(Co-Ni-MnO_(2)/Zn)battery that yields significantly better electrochemical performance,finding that the synergistic regulation of Co and Ni on MnO_(2)can significantly increase its intrinsic conductivity and achieve high rates and Coulombic efficiencies at large capacities.The aqueous Co-Ni-MnO_(2)/Zn battery exhibits a high rate(10C,100 mA cm^(-2)),high Coulombic efficiency(91.89%),and excellent cycling stability(600 cycles without decay)at a large areal capacity of 10 mAh cm^(-2).Our proposed strategy of co-regulation with transition metal ions offers a versatile approach for improving the electrochemical performance of aqueous electrolytic MnO_(2)/Zn batteries in large-scale energy storage applications.Mingyan Chuai Jinlong Yang Mingming Wang Yuan Yuan Zaichun Liu Yan Xu Yichen Yin Jifei Sun Xinhua Zheng Na Chen Wei Chen 2021eScience2021,1,2:8
5Onset velocity of circulating fluidization and particle residence time distribution:A CFD-DEM study显示文摘Until now,the onset velocity of circulating fluidization in liquid-solid fluidized beds has been defined by the turning point of the time required to empty a bed of particles as a function of the superficial liquid velocity,and is reported to be only dependent on the liquid and particle properties.This study presents a new approach to calculate the onset velocity using CFD-DEM simulation of the particle residence time distribution(RTD).The onset velocity is identified from the intersection of the fitted lines of the particle mean residence time as a function of superficial liquid velocity.Our results are in reasonable agreement with experimental data.The simulation indicates that the onset velocity is influenced by the density and size of particles and weakly affected by riser height and diameter.A power-law function is proposed to correlate the mean particle residence time with the superficial liquid velocity.The collisional parameters have a minor effect on the mean residence time of particles and the onset velocity,but influence the particle RTD,showing some humps and trailing.The particle RTD is found to be related to the particle trajectories,which may indicate the complex flow structure and underlying mechanisms of the particle RTD.Qiqi Han Ning Yang Jiahua Zhu Mingyan Liu 2015Particuology2015,13,4:8
6Archimedean copula estimation of distribution algorithm based on artificial bee colony algorithm显示文摘The artificial bee colony(ABC) algorithm is a competitive stochastic population-based optimization algorithm. However, the ABC algorithm does not use the social information and lacks the knowledge of the problem structure, which leads to insufficiency in both convergent speed and searching precision.Archimedean copula estimation of distribution algorithm(ACEDA)is a relatively simple, time-economic and multivariate correlated EDA. This paper proposes a novel hybrid algorithm based on the ABC algorithm and ACEDA called Archimedean copula estimation of distribution based on the artificial bee colony(ACABC)algorithm. The hybrid algorithm utilizes ACEDA to estimate the distribution model and then uses the information to help artificial bees to search more efficiently in the search space. Six benchmark functions are introduced to assess the performance of the ACABC algorithm on numerical function optimization. Experimental results show that the ACABC algorithm converges much faster with greater precision compared with the ABC algorithm, ACEDA and the global best(gbest)-guided ABC(GABC) algorithm in most of the experiments.Haidong Xu Mingyan Jiang Kun Xu 2015Journal of Systems Engineering and Electronics2015,26,2:8
7Effects of Ziyin Jianghuo Ningxin decoction plus dehydroepiandrosterone and femoston in treatment of patients with menopausal symptoms显示文摘OBJECTIVE: To determine the therapeutic effect of Ziyin Jianghuo Ningxin Decoction(ZYJHNXD) plus dehydroepiandrosterone(DHEA) and menopausalhormone therapy(MHT) in patients suffering from menopausal symptoms identified as, in terms of Traditional Chinese Medicine, symptom pattern of Yin deficiency with hyperactive fire.METHODS: Totally 180 postmenopausal women aged 40 to 60 years were assigned into four groups and accepted femoston, femoston with ZYJHNXD,femoston with DHEA, femoston with ZYJHNXD and DHEA therapies, respectively, for three months.Common questionnaire-based measure instruments included modified Kupperman index(MKI),Hamilton Rating Scale for Anxiety(HAMA), and Hamilton Rating Scale for Depression(HAMD). Follicle-stimulating hormone(FSH), luteinizing hormone(LH), estradiol(E2), 5-hydroxyindole-3-acetic acid(5-HIAA), norepinephrine(NE), dopamine(DA),bone mineral density(BMD), and sleep quality were evaluated before and three months after the treatments.RESULTS: In all four groups, the scores of MKI, HAMA, HAMD and the levels of FSH, LH decreased significantly(P < 0.05) after the treatment, while the levels of E2, 5-HIAA, NE, and DA showed obvious elevation(P < 0.05). The group receiving ZYJHNXD and DHEA combined with femoston had superiority in the preservation of bone mineral density and improvement of total sleep time and nighttime sleep time over the other three groups.CONCLUSION: ZYJHNXD and DHEA combined with MHT therapy have a favorable outcome in managing menopausal symptoms, restoring hormone levels, preventing skeletal rarefaction or osteoporosis,and improving sleep quality for postmenopausal women.Lin Jing Zhu Jun Tian Fubo Chen Lanting Zhang Yang Wang Yan Wang Mingyan Hans-Jurgen Gober Li Da-jin Wang Ling 2018Journal of Traditional Chinese Medicine2018,38,5:6
8Isolation and Characterization of Collagen from Squid(Ommastrephes bartrami) Skin显示文摘Collagen of squid(Ommastrephes bartrami) skin was examined in the present study. Histology showed that collagen fiber in the skin was partially cross-linked with muscle fiber. Acid-solubilized collagen(ASC) and pepsin-solubilized collagen(PSC) were extracted from the skin and characterized. The results of amino acid composition and electrophoretic patterns revealed that ASC and PSC were both type Ⅰ collagen,containing α1 and α2 chains. FTIR(fourier transform infrared spectroscopy) investigations confirmed the existence of helical arrangements in PSC of squid skin. The denaturation temperature(Td) and shrinkage temperature(Ts) of PSC were 29.4℃ and 52.8℃,respectively.YAN Mingyan LI Bafang ZHAO Xue 2009Journal of Ocean University of China2009,8,2:6
9Modeling of acute cadmium toxicity in solution to barley root elongation using biotic ligand model theory显示文摘Protons(H^+)as well as different major and trace elements may inhibit cadmium(Cd)uptake in aquatic organisms and thus alleviate Cd toxicity.However,little is known about such interactions in soil organisms.In this study,the independent effects of the cations calcium(Ca^(2+)),magnesium(Mg^(2+)),potassium(K^+),H+and zinc(Zn^(2+))on Cd toxicity were investigated with 5-day long barley root elongation tests in nutrient solutions.The tested concentrations of selected cations and trace metal ions were based on the ranges that occur naturally in soil pore water.The toxicity of Cd decreased with increasing activity of Ca^(2+),Mg^(2+),H^+and Zn^(2+),but not K^+.Accordingly,conditional binding constants were obtained for the binding of Cd^(2+),Ca^(2+),Mg^(2+),H^+,and Zn^(2+) with the binding ligand:log K_(CdBL)5.19,logK_(CaBL)2.87,logK_(MgBL)2.98,logK_(HBL)5.13 and logK_(ZnBL)5.42,respectively.Furthermore,it was calculated that on average 29% of the biotic ligand sites needed to be occupied by Cd to induce a 50% decrease in root elongation.Using the estimated constants,a biotic ligand model was successfully developed to predict the Cd toxicity to barley root elongation as a function of solution characteristics.The feasibility and accuracy of its application for predicting Cd toxicity in soils were discussed.Xuedong Wang Mingyan Wu Jingxing Ma Xiaolin Chen Luo Hua 2016Journal of Environmental Sciences2016,28,4:6
10CD147 antibody specifically and effectively inhibits infection and cytokine storm of SARS-CoV-2 and its variants delta,alpha,beta,and gamma显示文摘SARS-CoV-2 mutations contribute to increased viral transmissibility and immune escape,compromising the effectiveness of existing vaccines and neutralizing antibodies.An in-depth investigation on COVID-19 pathogenesis is urgently needed to develop a strategy against SARS-CoV-2 variants.Here,we identified CD147 as a universal receptor for SARS-CoV-2 and its variants.Meanwhile,Meplazeumab,a humanized anti-CD147 antibody,could block cellular entry of SARS-CoV-2 and its variants-alpha,beta,gamma,and delta,with inhibition rates of 68.7,75.7,52.1,52.1,and 62.3%at 60μg/ml,respectively.Furthermore,humanized CD147 transgenic mice were susceptible to SARS-CoV-2 and its two variants,alpha and beta.When infected,these mice developed exudative alveolar pneumonia,featured by immune responses involving alveoli-infiltrated macrophages,neutrophils,and lymphocytes and activation of IL-17 signaling pathway.Mechanistically,we proposed that severe COVID-19-related cytokine storm is induced by a'spike protein-CD147-CyPA signaling axis':Infection of SARS-CoV-2 through CD147 initiated the JAK-STAT pathway,which further induced expression of cyclophilin A(CyPA);CyPA reciprocally bound to CD147 and triggered MAPK pathway.Consequently,the MAPK pathway regulated the expression of cytokines and chemokines,which promoted the development of cytokine storm.Importantly,Meplazumab could effectively inhibit viral entry and inflammation caused by SARS-CoV-2 and its variants.Therefore,our findings provided a new perspective for severe COVID-19-related pathogenesis.Furthermore,the validated universal receptor for SARS-CoV-2 and its variants can be targeted for COVID-19 treatment.Jiejie Geng Liang Chen Yufeng Yuan Ke Wang Youchun Wang Chuan Qin Guizhen Wu Ruo Chen Zheng Zhang Ding Wei Peng Du Jun Zhang Peng Lin Kui Zhang Yongqiang Deng Ke Xu Jiangning Liu Xiuxuan Sun Ting Guo Xu Yang Jiao Wu Jianli Jiang Ling Li Kun Zhang Zhe Wang Jing Zhang Qingguo Yan Hua Zhu Zhaohui Zheng Jinlin Miao Xianghui Fu Fengfan Yang Xiaochun Chen Hao Tang Yang Zhang Ying Shi Yumeng Zhu Zhuo Pei Fei Huo Xue Liang Yatao Wang Qingyi Wang Wen Xie Yirong Li Mingyan Shi Huijie Bian Ping Zhu Zhi-Nan Chen 2021Signal Transduction and Targeted Therapy2021,6,10:6

12Effect of chitooligosaccharides on cyclin D1,bcl-xl and bcl-2 mRNA expression in A549 cells using quantitative PCR显示文摘Chitooligosaccharide (COS) is derived from the chemical and enzymatic hydrolysis of chitosan and has been reported to have potent antitumor activity.Our study investigated the effects of five chitooligomers ranging from the dimer form to the hexamer form (chitobiose,chitotriose,chitotetraose,chitopentaose,chitohexaose) on the expression of cyclin D1,bcl-2 and bcl-xl mRNA in A549 cells using reverse transcription quantitative real-time PCR.We demonstrated that,of the five chitooligomers used,chitohexaose (COS6) had the most potent inhibitory effect on A549 cell proliferation.COS6 also significantly down regulated cyclin D1 and bcl-xl mRNA expression levels.Our data suggested that COS6 exerts its antitumor activity by two different mechanisms:(1) COS6-mediated inhibition of Cyclin D1 levels leads to suppression of tumor cell proliferation;and (2) COS6-mediated down-regulation of the pro-survival protein,Bcl-xl,promotes the apoptosis of tumor cells.LI Xian WANG Ju CHEN XiaoJia TIAN JinHuan LI LiHua ZHAO MingYan JIAO YanPeng ZHOU ChangRen 2011Chinese Science Bulletin2011,56,15:5
13Toward dendrite-free and anti-corrosion Zn anodes by regulating a bismuth-based energizer显示文摘Aqueous rechargeable zinc metal batteries display high theoretical capacity along with economical effectiveness,environmental benignity and high safety.However,dendritic growth and chemical corrosion at the Zn anodes limit their widespread applications.Here,we construct a Zn/Bi electrode via in-situ growth of a Bi-based energizer upon Zn metal surface using a replacement reaction.Experimental and theoretical calculations reveal that the Bi-based energizer composed of metallic Bi and ZnBi alloy contributes to Zn plating/stripping due to strong adsorption energy and fast ion transport rates.The resultant Zn/Bi electrode not only circumvents Zn dendrite growth but also improves Zn anode anti-corrosion performance.Specifically,the corrosion current of the Zn/Bi electrode is reduced by 90%compared to bare Zn.Impressively,an ultra-low overpotential of 12​mV and stable cycling for 4000​h are achieved in a Zn/Bi symmetric cell.A Zn–Cu/Bi asymmetric cell displays a cycle life of 1000 cycles,with an average Coulombic efficiency as high as 99.6%.In addition,an assembled Zn/Bi-activated carbon hybrid capacitor exhibits a stable life of more than 50,000 cycles,an energy density of 64​Wh kg−1,and a power density of 7​kW​kg−1.The capacity retention rate of a Zn/Bi–MnO_(2)full cell is improved by over 150%compared to a Zn–MnO_(2)cell without the Bi-based energizer.Our findings open a new arena for the industrialization of Zn metal batteries for large-scale energy storage applications.Mingming Wang Yahan Meng Ke Li Touqeer Ahmad Na Chen Yan Xu Jifei Sun Mingyan Chuai Xinhua Zheng Yuan Yuan Chunyue Shen Ziqi Zhang Wei Chen 2022eScience2022,2,5:4

15Clinical characteristics of 310 SARS-CoV-2 Omicron variant patients and comparison with Delta and Beta variant patients in China显示文摘Although the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron variant has spread,data on the clinical characteristics of infected patients are limited.In this study,the demographic,clinical characteristics,and laboratory data of 310 SARS-CoV-2 Omicron variant patients treated at Haihe Hospital of Tianjin were collected and analyzed.Information on these patients was compared to 96 patients with the Delta variant of concern(VOC)and 326 patients with the Beta VOC during the previous coronavirus disease 2019(COVID-19)outbreak in Harbin.Of the 310 patients infected with the Omicron variant,the median age was 35 years.Most patients were clinically classified as mild(57.74%),and the most common symptoms were cough(48.71%),fever(39.35%),and sore throat(38.26%).The results for different vaccination groups in the Omicron group showed that the median of“SARS-CoV-2 specific IgG”after 2 or 3 doses of vaccination was higher than the unvaccinated group(all Ps<0.05).Older age was associated with a higher proportion of moderate cases and lower asymptomatic and mild cases based on clinical classifications.Compared to the Delta and Beta groups,the median age of the Omicron group was younger.The total number of asymptomatic patients and mild patients in the Omicron virus group was higher than the Delta and Beta groups(60.97%vs.54.17%vs.47.55%).This study presented the clinical characteristics of the first group of patients infected with the Omicron variant in Tianjin,China,and compared their clinical features with patients infected by the Delta and Beta variants,which would increase our understanding of the characteristics of SARS-CoV-2 Omicron variant.Wei Yang Songliu Yang Lei Wang Yuxin Zhou Yu Xin Hongxu Li Wenjing Mu Qi Wu Lei Xu Mingyan Zhao Changsong Wang Kaijiang Yu 2022Virologica Sinica2022,37,5:4
16Clustering behavior of solid particles in two-dimensional liquid-solid fluidized-beds显示文摘In this paper, the clustering behavior of solid particles in a two-dimensional (2D) liquid-solid fluidized-bed was studied by using the charge coupled devices (CCD) imaging measuring and processing technique and was characterized by fractal analysis. CCD images show that the distribution of solid particles in the 2D liquid-solid fluidised-bed is not uniform and self-organization behavior of solid particles was observed under the present experimental conditions. The solid particles move up in the 2D fluidized-bed in groups or clusters whose configurations are often in the form of horizontal strands. The box fractal dimension of the cluster images in the 2D liquid-solid fluidized-bed increases with the rising of solid holdup and reduces with the increment of solid particle diameter and superficial liquid velocity. At given solid holdup and solid particle size, the lighter particles show smaller fractal dimensions.Xiaodong An Mingyan Liu Yunguan Fu 2007China Particuology2007,5,5:3
17Protective effects of catalpol and rhein in murine experimental autoimmune encephalomyelitis via regulation of T helper (Th)1, Th2,Th17, and regulatory T cell responses显示文摘OBJECTIVE:To examine the effects of catalpol and rhein on pro-and anti-inflammatory responses in C57 BL/6 mice with experimental autoimmune encephalomyelitis(EAE),a model of multiple sclerosis.METHODS:Female C57 BL/6 mice were randomly divided into four groups(n=30):(a)normal salinecontrol,(b)EAE control,(c)EAE+prednisone acetate(PA,6 mg/kg),and(d)EAE+catalpol(40 mg/kg)and rhein(5 mg/kg).EAE was induced by injection of myelin oligodendrocyte glycoprotein 35-55 plus pertussis toxin.Treatments were orally administered daily for 40 d.Disease progression and neurological function were assessed using a semi-quantitative scale of tail and limb paralysis.Brains and spinal cords were collected on Days 6,20,and 40 and assessed for histopathological changes by hematoxylin and eosin staining.Production of interleukin(IL)-2,IL-4,IL-10,and IL-17 A protein was measured by enzyme-linked immunosorbent assay.Expression of the T helper(Th)1-,Th2-,Th17-,and regulatory T cell(Treg)-specific transcription factors T-bet,GATA3,ROR-γt,and Foxp3,respectively,were analyzed by quantitative reverse-transcription polymerase chain reaction and western blot analysis.RESULTS:Combination treatment with catalpol and rhein significantly alleviated the clinical disability and neurological dysfunction of mice with EAE.Catalpol and rhein treatment also reduced the infiltration of pro-inflammatory T cells into pathological lesions;significantly increased the expression of the anti-inflammatory factors GATA3,Foxp3,IL-4,and IL-10;and significantly decreased the expression of the pro-inflammatory factors T-bet,ROR-γt,IL-2,and IL-17 A.CONCLUSION:Catalpol and rhein reduced the neurological disabilities of mice with EAE,at least in part by rebalancing the pro-and anti-inflammatory environment in the brains and spinal cords.Wei Mingyan Yang Tao Li Qian Zhou Dongdong Du Zongpan Fan Yongping 2019Journal of Traditional Chinese Medicine2019,39,6:3

19Metal porphyrin intercalated reduced graphene oxide nanocomposite utilized for electrocatalytic oxygen reduction显示文摘In this paper, we report a simple and facile self-assembly method to successfully fabricate cationic metal porphyrin-MtTMPyP(Mt= Cobalt(Ⅱ), Manganese(Ⅲ), or Iron(Ⅲ); TMPyP = 5, 10, 15, 20-tetrakis(N-methylpyridinium-4-yl) porphyrin) intercalated into the layer of graphene oxide(GO) by the cooperative effects of electrostatic and π-π stacking interaction between positively charged metal porphyrin and negatively charged GO sheets. Followed by reduction with hydrazine vapor, a series of novel 2 D MtTMPyP/rGO_n were fabricated. The as-prepared 2 D hybrids were fully characterized and tested as non-noble metal catalysts for oxygen reduction reaction(ORR) in an alkaline medium. The MtTMPyP/rGO_n hybrids, especially CoTMPyP/rGO_5, demonstrated an improved electrocatalytic activity for ORR and a number of exchanged electrons close to 4-electron reaction, increased stability and excellent tolerance to methanol, showing a potential alternative catalyst for ORR in fuel cells and air batteries.Mingyan Wang Qing Wang Wei Zhu Ying Yang Huixian Zhou Fan Zhang Lihua Zhou Joselito M.Razal Gordon G.Wallace Jun Chen 2017Green Energy & Environment2017,2,3:3
