1Changes of plasma C-reactive protein in patients with craniocerebral injury before and after hyperbaric oxygenation: A randomly controlled study显示文摘BACKGROUND: Plasma inflammatory factor, such as C-reactive protein, whose content is regarded as a sensitively pathological marked protein and quantitative indexes of central nervous system injury, has been paid more and more attention in clinic. OBJECTIVE: To observe the effects and clinical significance of C-reactive protein in patients with craniocerebral injury after hyperbaric oxygenation. DESIGN: Randomized controlled study. SETTING: Departments of Neurosurgery, Laboratory and Hyperbaric Oxygen, the Second Affiliated Hospital, Medical College of Shantou University. PARTICIPANTS: A total of 60 patients with craniocerebral injury were selected from Department of Neurosurgery, the Second Affiliated Hospital, Medical College of Shantou University from October 2006 to April 2007. There were 37 males and 23 females and the mean age was 26 years. All subjects were certainly diagnosed as history of craniocerebral injury. Patients hospitalized at 24 hours after injury, Glasgow Coma Score ranged from 3 to 12 points, and all patients were certainly diagnosed with CT or MR scanning. Patients and their relatives provided confirmed consent. All the subjects were randomly divided into hyperbaric oxygenation group and control group with 30 in each group. METHODS: Patients in the control group were treated with routinely neurosurgical therapy after hospitalization; however, based the same basic treatment in the control group, patients in the hyperbaric oxygenation group received hyperbaric oxygenation by using iced-wheel four-door 2-cabin air-compression chamber (made in Yantai) from 24 hours to 10 days after operation or injury. After entering the cabin, patients who had a clear consciousness breathed the oxygen by using face mask; contrarily, patients directly breathed the oxygen. Therapeutic project: Expression was increased for about 15–20 minutes, maintained for about 70–80 minutes, and decreased for 20 minutes. Otherwise, pressure was maintained from 0.2 to 0.25 MPa. Hyperbaric oxygenation took an hour for once a day and 10 times were regarded as a course. Venous blood was collected before treatment and on the next day of the first course end. Content of C-reactive protein in plasma was measured with immune turbidimetry in hyperbaric oxygenation group; in addition, content of C-reactive protein in plasma was directly measured with the same method at the corresponding time in the control group. If the content was less or equal to 8 mg/L, it was regarded as normal value. Effects of the two groups were evaluated based on Glasgow Coma Score before and after treatment. MAIN OUTCOME MEASURES: Content of plasma C-reactive protein and Glasgow Coma Score in the two groups before and after treatment. RESULTS: All 60 patients were involved in the final analysis. ① Content of plasma C-reactive protein: The two contents were obviously higher than normal value after craniocerebral injury. There was no significant difference in the two groups before treatment (P > 0.05), but both contents were decreased after treatment, and there was significant difference between HBOT group and control group after treatment (t =4.756, P < 0.01). In addition, there was significant difference in hyperbaric oxygen therapy group before and after treatment (t =5.236, P < 0.01). ② Glasgow Coma Score: There was no significant difference in the two groups before treatment (P > 0.05), but scores were increased in both groups after treatment (t =9.92, 2.51, P < 0.01, 0.05); on the other hand, therefore, there was significant difference between the two groupsafter treatment (t =9.21, P < 0.01). CONCLUSION: Hyperbaric oxygenation can remarkably decrease content of plasma C-reactive protein in patients with craniocerebral injury at the phase of stress.Zeyu Xie Minghua Zhuang Lan Lin Hongwu Xu Linxing Chen Lina Hu 2007Neural Regeneration Research2007,2,5:9

3A Sub-Nanostructural Transformable Nanozyme for Tumor Photocatalytic Therapy显示文摘The structural change-mediated catalytic activity regulation plays a significant role in the biological functions of natural enzymes.However,there is virtually no artificial nanozyme reported that can achieve natural enzyme-like stringent spatiotemporal structure-based catalytic activity regulation.Here,we report a subnanostructural transformable gold@ceria(STGC-PEG)nanozyme that performs tunable catalytic activities via near-infrared(NIR)light-mediated sub-nanostructural transformation.The gold core in STGC-PEG can generate energetic hot electrons upon NIR irradiation,wherein an internal sub-nanostructural transformation is initiated by the conversion between CeO;and electron-rich state of CeO;-x,and active oxygen vacancies generation via the hot-electron injection.Interestingly,the sub-nanostructural transformation of STGC-PEG enhances peroxidase-like activity and unprecedentedly activates plasmon-promoted oxidase-like activity,allowing highly efficient low-power NIR light(50 m W cm;)-activated photocatalytic therapy of tumors.Our atomic-level design and fabrication provide a platform to precisely regulate the catalytic activities of nanozymes via a light-mediated sub-nanostructural transformation,approaching natural enzyme-like activity control in complex living systems.Xi Hu Nan Wang Xia Guo Zeyu Liang Heng Sun Hongwei Liao Fan Xia Yunan Guan Jiyoung Lee Daishun Ling Fangyuan Li 2022Nano-Micro Letters2022,14,6:4

5Monolayer MoS_(2)-based transistors with low contact resistance by inserting ultrathin Al_(2)O_(3)interfacial layer显示文摘Transition metal dichalcogenides(TMDCs)are promising high performance electronic materials due to their interesting semiconductor properties.However,it is acknowledged that the effective electrical contact between TMDCs-layered materials and metals remains one of the major challenges.In this work,the homogeneous monolayer MoS_(2)films with high crystalline quality were prepared by chemical vapor deposition method on SiO2/Si substrates.The back-gate field-effect transistors(FETs)were fabricated by inserting an ultrathin Al_(2)O_(3)interlayer between the metal electrodes and MoS_(2)nanosheets.With the addition of an ultrathin 0.8 nm Al_(2)O_(3)interlayer,the contact resistance decreased dramatically from 59.9 to 1.3 kΩμm and the Schottky barrier height(SBH)dropped from 102 to 27 meV compared with devices without the Al_(2)O_(3)interlayer.At the same time,the switching ratio increased from~106to~108,and both the on-current and field-effect mobility were greatly improved.We find that the ultrathin Al_(2)O_(3)interlayer can not only reduce the SBH to alleviate the Fermi level pinning phenomenon at the interface,but also protect the channel materials from the influence of air and moisture as a covering layer.In addition,the lattice and band structures of Al_(2)O_(3)/MoS_(2)film were calculated and analyzed by first-principles calculation.It is found that the total density of states of the Al_(2)O_(3)/MoS_(2)film exhibits interfacial polarized metals property,which proves the higher carrier transport characteristics.FETs with Al_(2)O_(3)interlayers have excellent stability and repeatability,which can provide effective references for future low power and high performance electronic devices.CHEN Gang LIN Xin LIU Yuan WANG Fang HU Kai SHAN Xin WU ZeYu ZHANG YuPeng NIE WeiCan ZHONG JiXiang REN TianLing ZHANG KaiLiang 2023Science China(Technological Sciences)2023,66,6:2
6Genes in the serotonin pathway are associated with bipolar affective disorder in a Han Chinese population显示文摘Serotonin plays an important role in mood regulation, but the involvement of serotonin pathway genes in the development of bipolar I disorder (BP-I), a mood disorder, is not clear. We selected 21 singlenucleotide polymorphisms (SNPs) within the HTR2A gene, 8 within the SLC6A4 gene and 23 within the TPH2 gene for genotyping using the GoldenGate genotyping assay. A total of 375 patients with BP-I and 475 normal controls were recruited. Two out of 21 SNPs (rs1475196 and rs9567747) in the HTR2A gene and 1/23 SNPs (rs17110566) in the TPH2 gene were significantly associated with BP-I, both genotype-wise and allele-wise. Furthermore, a specific haplotype in the HTR2A gene showed a significant association with BP-I. Our results indicate that the HTR2A and TPH2 genes in the serotonin pathway play important roles in susceptibility to BP-I.Bo Xiang Zhenxing Yang Yin Lin Lijie Guan Xuan Li Wei Deng Zeyu Jiang Guohui Lao Qiang Wang Xiaoyu Hao Xiang Liu Yingcheng Wang Liansheng Zhao Xiaohong Ma Tao Li Liping Cao Xun Hu 2014Neuroscience Bulletin2014,30,1:2
7Cooling effect of ballast revetment on the roadbed of Qinghai-Tibetan Railway显示文摘The data obtained through the roadbed surface thermal regime experiment (ROBSTREX), which was carried out at Beiluhe test section of Qinghai-Tibetan Railway from October to December in 2002, were used to estimate the cooling effect of ballast revetment on the roadbed. The results show that both riprap rock ballast revetment and crushed stone ballast revetment can reduce the temperature of the roadbed. But the cooling effect of riprap rock ballast revetment is better than that of crushed stone ballast revetment when the temperature of roadbed is higher. The cooling effect of crushed stone ballast revetment is better than that of riprap rock ballast revetment when the temperature of the roadbed is lower, especially at deeper roadbed layers. In the frozen season, the heat release from the roadbed also shows that the cooling effect of ballast revetment on the roadbed is obvious, and the cooling effect of crushed stone-ballast revetment on the roadbed is much evident than that of riprap rock ballast revetment.HU Zeyong CHENG Guodong QIAN Zeyu WANG Jiemin WEI Guoan HOU Xuhong GU Lianglei YAN Yuping 2004Science China Earth Sciences2004,47,z1:2
8Mode selection and high-quality upconversion lasing from perovskite CsPb2Br5 microplates显示文摘In recent years,halide perovskite nanostructures have had great advances and have opened up a bright future for micro/nanolasers.However,upconversion lasing by two-photon excitation with mode selection and high quality factor in one device is still rarely reported.Herein,two lasing modes are demonstrated in the all-inorganic perovskite CsPb2Br5 microplates with subwavelength thickness and uniform square shape.The net optical gain is quickly established in less than 1 ps and persists more than 30 ps,revealed by ultrafast transient absorption spectroscopy.The temperature-dependent low-threshold amplified spontaneous emission confirms the net gain for stimulated emission with a high characteristic temperature of 403 K,far surpassing the all-inorganic CsPbBr3 semiconductor gain media.Remarkably,upconversion lasing based on two kinds of microcavity effects,Fabry–Pérot and whispering-gallery modes,from the microplates at room temperature is successfully achieved with a low threshold operating in multi-or single-mode,respectively.Surprisingly,the quality factor(~3551)is among the best values obtained from perovskite micro/nanoplate upconversion lasers without an external cavity.Moreover,the highly stable chromaticity with color drift only less than 0.1 nm also outbalances the all-inorganic CsPbBr3 ones.These superior performances of CsPb2Br5 microplate lasing with a facile solution synthesis procedure will offer a feasible structure to fabricate specific functionalities for high-performance frequency upconversion micro/nanoscale photonic integrated devices.ZHENGZHENG LIU CHUNWEI WANG ZHIPING HU JUAN DU JIE YANG ZEYU ZHANG TONGCHAO SHI WEIMIN LIU XIAOSHENG TANG AND YUXIN LENG 2020Photonics Research2020,8,9:2
9The Corylus mandshurica genome provides insights into the evolution of Betulaceae genomes and hazelnut breeding显示文摘Hazelnut is popular for its flavor,and it has also been suggested that hazelnut is beneficial to cardiovascular health because it is rich in oleic acid.Here,we report the first high-quality chromosome-scale genome for the hazelnut species Corylus mandshurica(2n=22),which has a high concentration of oleic acid in its nuts.The assembled genome is 367.67Mb in length,and the contig N50 is 14.85 Mb.All contigs were assembled into 11 chromosomes,and 28,409 protein-coding genes were annotated.We reconstructed the evolutionary trajectories of the genomes of Betulaceae species and revealed that the 11 chromosomes of the hazelnut genus were derived from the most ancestral karyotype in Betula pendula,which has 14 protochromosomes,by inferring homology among five Betulaceae genomes.We identified 96 candidate genes involved in oleic acid biosynthesis,and 10 showed rapid evolution or positive selection.These findings will help us to understand the mechanisms of lipid synthesis and storage in hazelnuts.Several gene families related to salicylic acid metabolism and stress responses experienced rapid expansion in this hazelnut species,which may have increased its stress tolerance.The reference genome presented here constitutes a valuable resource for molecular breeding and genetic improvement of the important agronomic properties of hazelnut.Ying Li Pengchuan Sun Zhiqiang Lu Jinyuan Chen Zhenyue Wang Xin Du Zeyu Zheng Ying Wu Hongyin Hu Jiao Yang Jianxiang Ma Jianquan Liu Yongzhi Yang 2021Horticulture Research2021,8,1:1
10Probing the active sites of 2D nanosheets with Fe-N-C carbon shell encapsulated Fe_(x)C/Fe species for boosting sodium-ion storage performances显示文摘Developing stable but high active metal-nitrogen-carbon(M-N-C)-based hard carbon anode is a promising way to be the alternatives to graphene and blank hard carbon for sodium-ion batteries(SIBs),requiring the precise tailoring of the electronic structure for optimizing the Na+intercalation behavior,yet is greatly challenging.Herein,Fe-N-C graphitic layer-encapsulating Fe3C species within hard carbon nanosheets(Fe-N-C/Fe3C@HCNs)are rationally engineered by pyrolysis of self-assembled polymer.Impressively,the Fe-N-C/Fe3C@HCNs exhibit outstanding rate capacity(242 mAh·g^(−1)at 2,000 mA·g^(−1)),which is 2.1 and 4.2 times higher than that of Fe-N-C and N-doped carbon(N-C),respectively,and prolonged cycling stability(176 mAh·g^(−1)at 2,000 mA·g^(−1)after 2,000 cycles).Theoretical calculations unveil that the Fe3C species enhance the electronic transfer from Na to Fe-N-C,resulting in the charge redistribution between the interfaces of Fe3C and Fe-N-C.Thus,the optimized adsorption behavior towards Na+reduces the thermodynamic energy barriers.The synergistic effect of Fe3C and Fe-N-C species maintains the structural integrity of electrode materials during the sodiation/desodiation process.The in-depth insight into the advanced Na+storage mechanisms of Fe3C@Fe-N-C offers precise guidance for the rational establishment of confinement heterostructures in SIBs.Huicong Xia Pengfei Yuan Lingxing Zan Gan Qu Yunchuan Tu Kaixin Zhu Yifan Wei Zeyu WeiFangying Zheng Mo Zhang Yongfeng Hu Dehui Deng Jianan Zhang 2022Nano Research2022,15,8:1
11Molecular mechanisms of adaptive evolution in wild animals and plants显示文摘Wild animals and plants have developed a variety of adaptive traits driven by adaptive evolution,an important strategy for species survival and persistence.Uncovering the molecular mechanisms of adaptive evolution is the key to understanding species diversification,phenotypic convergence,and inter-species interaction.As the genome sequences of more and more non-model organisms are becoming available,the focus of studies on molecular mechanisms of adaptive evolution has shifted from the candidate gene method to genetic mapping based on genome-wide scanning.In this study,we reviewed the latest research advances in wild animals and plants,focusing on adaptive traits,convergent evolution,and coevolution.Firstly,we focused on the adaptive evolution of morphological,behavioral,and physiological traits.Secondly,we reviewed the phenotypic convergences of life history traits and responding to environmental pressures,and the underlying molecular convergence mechanisms.Thirdly,we summarized the advances of coevolution,including the four main types:mutualism,parasitism,predation and competition.Overall,these latest advances greatly increase our understanding of the underlying molecular mechanisms for diverse adaptive traits and species interaction,demonstrating that the development of evolutionary biology has been greatly accelerated by multi-omics technologies.Finally,we highlighted the emerging trends and future prospects around the above three aspects of adaptive evolution.Yibo Hu Xiaoping Wang Yongchao Xu Hui Yang Zeyu Tong Ran Tian Shaohua Xu Li Yu Yalong Guo Peng Shi Shuangquan Huang Guang Yang Suhua Shi Fuwen Wei 2023Science China(Life Sciences)2023,66,3:1

13High mass loading Ni_(4)Co_(1)-OH@CuO core-shell nanowire arrays obtained by electrochemical reconstruction for alkaline energy storage显示文摘The design of three-dimensional(30)core-shell hetercistructures is an efficient method to achieve high mass specific capacity of electroactive materials under high mass loading.In this work,porous Ni_(4)Co1-0H nanosheets with a mass loading of 7.7 mg·cm^(-2) are obtained by using Ni_(4)Cor(NO_(3))_(2)(0H)_(4) supported on the CuO nanowires as precursors via an unavoidable electrochemically induced phase reconstruction.During the electrochemical reconstruction process,the N03-anions in Ni_(4)Cor(N0_(3))_(2)(0H)_(4) are easily replaced by OH-anions in the electrolyte.The phase reconstruction is accompanied by the decrease of ionic diffusion.:resistance and the increase of pore volume,and the shift of binding energy.The obtained Ni4Co1-0H nanosheets show a high:mass specific capacity of 363.6 mAh·g^(-1) at 5 mA·cm^(-2).The as-fabricated alkaline hybrid supercapacitor and Ni-Zn battery deliver high energy density of 293.1 and 604.9 Wh·kg^(-1),respectively,indicating.excellent alkaline energy storage performance.Yawei Yu Xiulan Hu Shuai Wang Handan Qiao Zeyu Liu Kefan Song Xiaodong Shen 2022Nano Research2022,15,1:1

16Shigellosis seasonality and transmission characteristics in different areas of China: A modelling study显示文摘Objective:In China,the burden of shigellosis is unevenly distributed,notably across various ages and geographical areas.Shigellosis temporal trends appear to be seasonal.We should clarify seasonal warnings and regional transmission patterns.Method:This study adopted a Logistic model to assess the seasonality and a dynamics model to compare the transmission in different areas.The next-generation matrix was used to calculate the effective reproduction number(Reff)to quantify the transmissibility.Results:In China,the rate of shigellosis fell from 35.12 cases per 100,000 people in 2005 to 7.85 cases per 100,000 people in 2017,peaking in June and August.After simulation by the Logistic model,the‘peak time’is mainly concentrated from mid-June to mid-July.China's‘early warning time’is primarily focused on from April to May.We predict the‘peak time’of shigellosis is the 6.30th month and the‘early warning time’is 3.87th month in 2021.According to the dynamics model results,the water/food transfer pathway has been mostly blocked off.The transmissibility of different regions varies greatly,such as the mean Reff of Longde County(3.76)is higher than Xiamen City(3.15),higher than Chuxiong City(2.52),and higher than Yichang City(1.70).Conclusion:The‘early warning time’for shigellosis in China is from April to May every year,and it may continue to advance in the future,such as the early warning time in 2021 is in mid-March.Furthermore,we should focus on preventing and controlling the personto-person route of shigellosis and stratified deploy prevention and control measures according to the regional transmission.Zeyu Zhao Meng Yang Jinlong Lv Qingqing Hu Qiuping Chen Zhao Lei Mingzhai Wang Hao Zhang Xiongjie Zhai Benhua Zhao Yanhua Su Yong Chen Xu-Sheng Zhang Jing-An Cui Roger Frutos Tianmu Chen 2022Infectious Disease Modelling2022,7,2:1

18Experimental study on mechanical properties of a novel micro-steel fiber reinforced magnesium phosphate cement-based concrete显示文摘Magnesium phosphate cement(MPC)received increased attention in recent years,but MPC-based concrete is rarely reported.The micro-steel fibers(MSF)were added to MPC-based concrete to enhance its ductility due to the high brittleness in tensile and flexural strength properties of MPC.This paper investigates the effect of MSF volume fraction on the mechanical properties of a new pattern of MPC-based concrete.The temperature development curve,fluidity,cubic compressive strength,modulus of elastic,axial compressive strength,and four-point flexural strength were experimentally studied with 192 specimens,and a scanning electron microscopy(SEM)test was carried out after the specimens were failed.Based on the test results,the correlations between the cubic compressive strength and curing age,the axial and cubic compressive strength of MPC-based concrete were proposed.The results showed that with the increase of MSF volume fraction,the fluidity of fresh MPC-based concrete decreased gradually.MSF had no apparent influence on the compressive strength,while it enhanced the four-point flexural strength of MPC-based concrete.The four-point flexural strength of specimens with MSF volume fraction from 0.25%to 0.75%were 12.3%,21.1%,24.6%higher than that of the specimens without MSF,respectively.Wenwen ZHU Xiamin HU Jing ZHANG Tao LI Zeyu CHEN Wei SHAO 2021Frontiers of Structural and Civil Engineering2021,15,4:0
19Hybeanones A and B,Two Highly Modified Polycyclic Polyprenylated Acylphloroglucinols from Hypericum beanii显示文摘Hybeanones A and B(1 and 2),two highly oxygenated and rearranged polycyclic polyprenylated acylphloroglucinols(PPAPs),were isolated from the aerial parts of Hypericum beanii.Their structures comprising absolute configurations were elucidated by spectroscopic analysis,single-crystal X-ray diffraction,and quantum chemical calculations.Compounds 1 and 2 are defined by a newly assembled cyclopentanone unit fused to a tricyclic γ-lactone unit via a ketone carbonyl.The breakage of C-1/C-2 linkage via retro-Claisen reaction,attack from C-1 to C-19,and Baeyer-Villiger oxidation at C-1/C-23 bond were presumed to be the key steps in the assembly of 1 and 2.The isolates 1 and 2 showed potential acetylcholinesterase(AchE)inhibitory activities,with IC50 values of 21.34±1.48 and 18.79±2.36μmol/L,respectively.Beiye Yang Changxing Qi Zeyu Yao Shuang Lin Fengli Li Weiguang Sun Zhengxi Hu Yonghui Zhang 2022Chinese Journal of Chemistry2022,40,1:0
