| 2 | Mechanical properties and corrosion behavior of selective laser melted 316L stainless steel after different heat treatment processes显示文摘Irregular grains, high interfacial stresses and anisotropic properties widely exist in 3D-printed metallic materials, and this paper investigated the effects of heat treatment on the microstructural, mechanical and corrosion properties of 316 L stainless steel fabricated by selective laser melting. Sub-grains and low-angle boundaries exist in the as-received selective laser melted(SLMed) 316 L stainless steel. After heat treatment at 1050℃, the sub-grains and low-angle boundaries changed slightly, and the stress state and strength decreased to some extent due to the decrease of dislocation density. After heat treatment at 1200℃, the grains became uniform, and the dislocation cells vanished, which led to a sharp decline in the hardness and strength. However, the ductility was improved after recrystallization heat treatment.The passive film thickness and corrosion potential of the SLMed 316 L stainless steel decreased after heat treatment, and the pitting potential also decreased due to the accelerated transition from metastable to steady-state pitting;this accelerated transition was caused by the presence of weak passive films at the enlarged pores after heat treatment, especially for an adequate solid solution treatment. | Decheng Kong Chaofang Dong Xiaoqing Ni Liang Zhang Jizheng Yao Cheng Man Xuequn Cheng Kui Xiao Xiaogang Li | 2019 | Journal of Materials Science & Technology2019，35，7： | 23 |

| 5 | Hot deformation behavior of Mg-7.22Gd-4.84Y-1.26Nd-0.58Zr magnesium alloy显示文摘The behavior evolvement of Mg-7.22Gd-4.84Y-1.26Nd-0.58Zr(GWN751K) magnesium alloy during the hot deformation process was discussed.The flow stress behavior of the magnesium alloy over the strain rate range of 0.002 to 2.000 s-1 and in the temperature range of 623 to 773 K was studied on a Gleeble-1500D hot simulator under the maximum deformation degree of 60%.The experimental results showed that the relationship between stress and strain was obviously affected by strain rate and deformation temperature.The flow stress of GWN751K magnesium alloy during high temperature deformation could be represented by the Zener-Hollomon parameter in the hyperbolic Arrhenius-type equation.The stress exponent n and deformation activation energy Q were evaluated by linear regression analysis.The stress exponent n was fitted to be 3.16.The hot deformation activation energy of the alloy during hot deformation was 230.03 kJ/mol.The microstructures of hot deformation were also influenced by strain rate and compression temperature strongly.It was found that the alloy could be extruded at 723 K with the mechanical properties of σ0.2 = 260 MPa,σb = 320 MPa,and δ = 18%. | ZHANG Kui MA Minglong LI Xinggang LI Yongjun LIANG Lichao BING Mengfen | 2011 | Rare Metals2011，30，1： | 13 |
| 6 | Molecularly imprinted macroporous monolithic materials for protein recognition显示文摘Synthetic materials that can specifically recognize proteins will find wide application in many fields.In this report,bovine serum albumin was chosen as the template protein.Acrylamide and N,N'-methylenebisacrylamide were employed as the functional and cross-linker monomers,respectively.Molecularly imprinted macroporous monolithic materials that can preferentially bind the template protein in an aqueous environment were prepared by combination of molecular imprinting technique and freezing/thawing preparation method.The resulted imprinted macroporous monolithic columns were evaluated by utilizing as stationary phase in high performance liquid chromatography and solid-phase extraction materials.The experimental results indicated that the imprinted macroporous monolithic column exhibited good recognition for template protein,as compared with the control protein(hemoglobin),whereas the non-imprinted polymer(prepared under the same conditions except without addition template protein) had no selective properties. | Qi Liang Deng Yan Li Li Li Hua Zhang Yu Kui Zhang | 2011 | Chinese Chemical Letters2011，22，11： | 8 |
| 7 | The Relationship between Polymorphisms at 17 Gene Sites and Hypertension among the Aboriginal Tibetan People显示文摘Objective The incidence of hypertension in Tibet ranks highest among all Chinese provinces. This may be due to genetic changes caused by Tibet's unique natural environment and agrarian lifestyle, prompting us to investigated the relationship between gene polymorphisms and hypertension. Methods Blood samples were collected from 229 hypertensive participants and 372 healthy (control) participants from five Tibetan counties. Seventeen single nucleotide polymorphisms were investigated for their connection to hypertension. Results The C allele at rs2070744 of the NOS3 gene was shown to be significantly associated with hypertension (P=0.0443; OR=1.636). Additionally, the T allele of rs4961 of the ADD gene was correlated with hypertension in women (P=0.03124; OR=1.584). Conclusion In this study we found that the NOS3 and ADD genes were related to a high incidence of hypertension among Tibetans. NOS3 gene plays a role in regulating vascular tone and blood vessel diameter, which may be altered by the low-oxygen environment of Tibet. ADD is involved in water and salt metabolism, which is consistent with the high-salt diet of Tibetans. The correlations elucidated by our study were different from those of other ethnic groups, indicating that these findings may be specific to the Tibetan people. | LI Kui LIANG Yu SUN Yin ZHANG Ling Xia YI Xin CHEN Yong GU SANG LA MU WANG Jian | 2012 | Biomedical and Environmental Sciences2012，25，5： | 6 |
| 8 | Dynamic Expression of MicroRNA-127 During Porcine Prenatal and Postnatal Skeletal Muscle Development显示文摘MicroRNAs(miRNAs), evolutionarily conserved non-coding RNAs in length 21-24 bp, play a critical role in skeletal muscle development. In this study, to explore the function of mircoRNA-127 in porcine skeletal muscle development, eight tissue samples from adult pigs and longissimus muscle samples at 26 developmental stages were collected from Tongcheng and Landrace pigs. The spatial-temporal expression profiles of miRNA-127 were carried out using step-loop quantitative real-time PCR(stemloop RT-PCR). To explore the molecular functions of miRNA-127, we predicted its target genes and performed functional annotation using bioinformatics methods. Results suggested that miRNA-127 was abundantly expressed in heart, ovary, uterus and spleen tissues and was weakly expressed in liver, lung, kidney and small intestine in both Tongcheng and Landrace pigs. And miRNA-127 showed significant expression differences in heart, ovary, spleen and uterus tissues between these two breeds. miRNA-127 basically kept at a relatively stable high level in middle and later embryonic stages and a low expression level in early embryonic stages and postnatal stages, but the expression levels of miRNA-127 were higher in Tongcheng pigs than in Landrace at most developmental stages. miRNA-127 potentially regulated 240 candidate genes. Results of Gene Ontology and KEGG pathway analysis indicated that these genes could be involved in many molecular functions and mechanisms, such as regulation of the force of heart contraction, regulation of transcription, regulation of T cell differentiation, MAPK signaling pathway and GnRH signaling pathway. Many significantly enriched GO terms and KEGG pathways were related to skeletal muscle development. This study will be helpful to understand the biological function for miRNA-127 and identify candidate gene associated with meat production traits in pigs. | YANG Ya-lan LI Yan LIANG Ru-yi ZHOU Rong AO Hong MU Yu-lian YANG Shu-lin LI Kui TANG Zhong-lin | 2014 | Journal of Integrative Agriculture2014，13，6： | 6 |
| 9 | CD147 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 | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 6 |
| 10 | Relationship between Dyslipidemia and Gene Polymorphism in Tibetan Population显示文摘Objective To inves gate the rela onship between SNPs reported in previous studies and the blood lipid level in the Tibetan popula on.Methods Random cluster sampling was employed in 5 areas (Lhasa,Shigatse,Shannan,Nagqu,and Nyingchi).The levels of cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C),and low-density lipoprotein cholesterol (LDL-C) from blood samples were determined and DNA was extracted for genotyping and sta s cal analyses.Results Among 1 318 subjects aged >18 years enrolled in this study,367 had dyslipidemia with a prevalence of 27.8%,of whom dyslipidemia males accounted for 33.1% and dyslipidemia females 24.5%.Results of the correla on analysis between all SNPs and TG showed that the SNPs of rs714052 and rs964184 were related to the serum TG level.Subjects with rs714052 CC genotype had the lowest TG level,and the highest TG level was found in those with rs714052 TT genotype.The serum TG level in individuals with TC genotype lied in between the above two popula on groups.Subjects with rs964184 CC genotype had the lowest TG level,and the highest serum TG level was noted in those with rs964184 GG genotype.Conclusion Several SNPs were found to be related to the serum TG level in the Tibetan popula on.The APOA5 gene and MLXIPL gene may be closely associated with the serum TG level in this ethnic popula on group. | ZHANG Ling Xia SUN Ying LIANG Yu LI Kui CHEN Yong GUSANGLAMU WANG Jian | 2012 | Biomedical and Environmental Sciences2012，25，3： | 5 |
| 11 | Exposure Effects of Terahertz Waves on Primary Neurons and Neuron-like Cells Under Nonthermal Conditions显示文摘Objective This study aimed to explore the potential effects of terahertz(THz) waves on primary cultured neurons from 4 rat brain regions(hippocampus, cerebral cortex, cerebellum, and brainstem)and 3 kinds of neuron-like cells(MN9 D, PC12, and HT22 cells) under nonthermal conditions.Methods THz waves with an output power of 50(0.16 THz) and 10(0.17 THz) m W with exposure times of 6 and 60 min were used in this study. Analysis of temperature change, neurite growth, cell membrane roughness, micromorphology, neurotransmitters and synaptic-related proteins(SYN and PSD95) was used to evaluate the potential effects.Results Temperature increase caused by the THz wave was negligible. THz waves induced significant neurotransmitter changes in primary hippocampal, cerebellar, and brainstem neurons and in MN9 D and PC12 cells. THz wave downregulated SYN expression in primary hippocampal neurons and downregulated PSD95 expression in primary cortical neurons.Conclusion Different types of cells responded differently after THz wave exposure, and primary hippocampal and cortical neurons and MN9 D cells were relatively sensitive to the THz waves. The biological effects were positively correlated with the exposure time of the THz waves. | TAN Sheng Zhi TAN Peng Cheng LUO Lan Qing CHI Yun Liang YANG Zi Long ZHAO Xue Long ZHAO Li DONG Ji ZHANG Jing YAO Bin Wei XU Xin Ping TIAN Guang CHEN Jian Kui WANG Hui PENG Rui Yun | 2019 | Biomedical and Environmental Sciences2019，32，10： | 5 |

| 15 | CO_(2) mineralization of carbide slag for the production of light calcium carbonates显示文摘The production of polyvinyl chloride by calcium carbide method is a typical chemical process with high coal consumption,leading to massive flue gas and carbide slag emissions.Currently,the carbide slag with high CaO content is usually stacked in residue field,easily draining away with the rain and corroding the soil.In this work,we coupled the treatment of flue gas and carbide slag to propose a facile CO_(2)mineralization route to prepare light calcium carbonate.And the route feasibility was comprehensively evaluated via experiments and simulation.Through experimental investigation,the Ca^(2+) leaching and mineralization reaction parameters were determined.Based on the experiment,a process was built and optimized through Aspen Plus,and the energy was integrated to obtain the overall process energy and material consumption.Finally,the net CO_(2)emission reduction rate of the entire process through the life-cycle assessment method was analyzed.Moreover,the relationship between the parameters and the CO_(2)emission life-cycle assessment was established.The final optimization results showed that the mineralization process required 1154.69 kW·h·(t CO_(2))^(-1) of energy(including heat energy of 979.32 kW·h·(t CO_(2))^(-1) and electrical energy of 175.37 kW·h·(t CO_(2))^(-1)),and the net CO_(2)emission reduction rate was 35.8%.The light CaCO_(3)product can be sold as a high value-added product.According to preliminary economic analysis,the profit of mineralizing can reach more than 2,100 CNY·(t CO_(2))^(-1). | Tongyang Zhang Guanrun Chu Junlin Lyu Yongda Cao Wentao Xu Kui Ma Lei Song Hairong Yue Bin Liang | 2022 | Chinese Journal of Chemical Engineering2022，35，3： | 4 |
| 16 | Stress corrosion cracking behavior of PH13-8Mo stainless steel in Cl^- solutions显示文摘The stress corrosion cracking( SCC) behavior of PH13-8Mo precipitation hardening stainless steel( PHSS) in neutral NaCl solutions was investigated through slow-strain-rate tensile( SSRT) test at various applied potentials. Fracture morphology,elongation ratio,and percentage reduction of area were measured to evaluate the SCC susceptibility. A critical concentration of 1. 0 mol / L neutral NaCl existed for SCC of PH13-8Mo steel. Significant SCC emerged when the applied potential was more negative than -0. 15 V_(SCE),and the SCC behavior was controlled by an anodic dissolution( AD) process.When the applied potential was lower than -0. 55 V_(SCE),an obvious hydrogen-fracture morphology was observed,which indicated that the SCC behavior was controlled by hydrogen-induced cracking( HIC).Between -0. 15 and -0. 35 V_(SCE),the applied potential exceeded the equilibrium hydrogen evolution potential in neutral NaCl solutions and the crack tips were of electrochemical origin in the anodic region; thus,the SCC process was dominated by the AD mechanism. | Qiang Yu Chao-fang Dong Jian-xiong Liang Zhen-bao Liu Kui Xiao Xiao-gang Li | 2017 | Journal of Iron and Steel Research(International)2017，24，3： | 4 |
| 17 | Progress and perspective of the cathode/electrolyte interface construction in all-solid-state lithium batteries显示文摘Security risks of flammability and explosion represent major problems with the use of conventional lithium rechargeable batteries using a liquid electrolyte.The application of solid-state electrolytes could effectively help to avoid these safety concerns.However,integrating the solid-state electrolytes into the all-solid-state lithium batteries is still a huge challenge mainly due to the high interfacial resistance present in the entire battery,especially at the interface between the cathode and the solid-state electrolyte pellet and the interfaces inside the cathode.Herein,recent progress made from investigations of cathode/solid-state electrolyte interfacial behaviors including the contact problem,the interlayer diffusion issue,the space-charge layer effect,and electrochemical compatibility is presented according to the classification of oxide-,sulfide-,and polymer-based solid-state electrolytes.We also propose strategies for the construction of ideal next-generation cathode/solid-state electrolyte interfaces with high room-temperature ionic conductivity,stable interfacial contact during long cycling,free formation of the space-charge region,and good compatibility with high-voltage cathodes. | Shiming Su Jiabin Ma Liang Zhao Kui Lin Qidong Li Shasha Lv Feiyu Kang Yan-Bing He | 2021 | Carbon Energy2021，3，6： | 3 |
| 18 | Spectral matching algorithm based on nonsubsampled contourlet transform and scale-invariant feature transform显示文摘A new spectral matching algorithm is proposed by using nonsubsampled contourlet transform and scale-invariant feature transform.The nonsubsampled contourlet transform is used to decompose an image into a low frequency image and several high frequency images,and the scale-invariant feature transform is employed to extract feature points from the low frequency image.A proximity matrix is constructed for the feature points of two related images.By singular value decomposition of the proximity matrix,a matching matrix(or matching result) reflecting the matching degree among feature points is obtained.Experimental results indicate that the proposed algorithm can reduce time complexity and possess a higher accuracy. | Dong Liang Pu Yan Ming Zhu Yizheng Fan Kui Wang | 2012 | Journal of Systems Engineering and Electronics2012，23，3： | 3 |
| 19 | Characterization and validation of somatic mutation spectrum to reveal heterogeneity in gastric cancer by single cell sequencing显示文摘Gastric cancer(GC) is a highly heterogeneous disease with multiple cellular types and poor prognosis.However, the cellular evolution and molecular basis of GC at the individual intra-tumor level has not been well demonstrated. We performed single-cell whole exome sequencing to detect somatic singlenucleotide variants(SNVs) and significantly mutated genes(SMGs) among 34 tumor cells and 9 normal cells from a patient with GC. The Complete Prediction for Protein Conformation(CPPC) approach directly predicting the folding conformation of the protein 3D structure with Protein Folding Shape Code, combined with functional experiments were used to confirm the characterization of mutated SMGs in GC cells. We identified 201 somatic SNVs, including 117 non-synonymous mutations in GC cells. Further analysis identified 24 significant mutated genes(SMGs) in single cells, for which a single amino acid change might affect protein conformation. Among them, two genes(CDC27 and FLG) that were mutated only in single cells but not in the corresponding tumor tissue, were recurrently present in another GC tissue cohort, and may play a potential role to promote carcinogenesis, as confirmed by functional characterization. Our findings showed a mutational landscape of GC at intra-tumor level for the first time and provided opportunities for understanding the heterogeneity and individualized target therapy for this disease. | Lihua Peng Rui Xing Dongbing Liu Li Bao Wenxiang Cheng Hongyi Wang Yuan Yu Xiaofeng Liu Lu Jiang Yan Wu Zhongxue An Qiaoyi Liang Ryong Nam Kim Young Kee Shin Huanming Yang Jian Wang Jun Yu Xiuqing Zhang Xun Xu Jiaan Yang Kui Wu Shida Zhu Youyong Lu | 2019 | Science Bulletin2019，64，4： | 3 |
| 20 | Safety and efficacy of meplazumab in healthy volunteers and COVID-19 patients: a randomized phase 1 and an exploratory phase 2 trial显示文摘Recent evidence suggests that CD147 serves as a novel receptor for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection.Blocking CD147 via anti-CD147 antibody could suppress the in vitro SARS-CoV-2 replication.Meplazumab is a humanized anti-CD147 IgG_(2) monoclonal antibody,which may effectively prevent SARS-CoV-2 infection in coronavirus disease 2019(COVID-19)patients.Here,we conducted a randomized,double-blinded,placebo-controlled phase 1 trial to evaluate the safety,tolerability,and pharmacokinetics of meplazumab in healthy subjects,and an open-labeled,concurrent controlled add-on exploratory phase 2 study to determine the efficacy in COVID-19 patients.In phase 1 study,59 subjects were enrolled and assigned to eight cohorts,and no serious treatment-emergent adverse event(TEAE)or TEAE grade≥3 was observed.The serum and peripheral blood Cmax and area under the curve showed non-linear pharmacokinetic characteristics.No obvious relation between the incidence or titer of positive anti-drug antibody and dosage was observed in each cohort.The biodistribution study indicated that meplazumab reached lung tissue and maintained>14 days stable with the lung tissue/cardiac blood-pool ratio ranging from 0.41 to 0.32.In the exploratory phase 2 study,17 COVID-19 patients were enrolled,and 11 hospitalized patients were involved as concurrent control.The meplazumab treatment significantly improved the discharged(P=0.005)and case severity(P=0.021),and reduced the time to virus negative(P=0.045)in comparison to the control group.These results show a sound safety and tolerance of meplazumab in healthy volunteers and suggest that meplazumab could accelerate the recovery of patients from COVID-19 pneumonia with a favorable safety profile. | Huijie Bian Zhao-Hui Zheng Ding Wei Aidong Wen Zheng Zhang Jian-Qi Lian Wen-Zhen Kang Chun-Qiu Hao Jing Wang Rong-Hua Xie Ke Dong Jie-Lai Xia Jin-Lin Miao Wen Kang Guoquan Li Di Zhang Mingru Zhang Xiu-Xuan Sun Likun Ding Kui Zhang Junfeng Jia Jin Ding Zhiqin Li Yanyan Jia Lin-Na Liu Zhe Zhang Zhao-Wei Gao Hong Du Na Yao Qing Wang Ke Wang Jie-Jie Geng Bin Wang Ting Guo Ruo Chen Yu-Meng Zhu Li-Juan Wang Qian He Rui-Rui Yao Ying Shi Xiang-Min Yang Jian-Sheng Zhou Yi-Nan Ma Ya-Tao Wang Xue Liang Fei Huo Zhe Wang Yang Zhang Xu Yang Ye Zhang Lu-Hua Gao Ling Wang Xiao-Chun Chen Hao Tang Shuang-Shuang Liu Qing-Yi Wang Zhi-Nan Chen Ping Zhu | 2021 | Signal Transduction and Targeted Therapy2021，6，6： | 2 |
