1Hydroxysafflor yellow A improves learning and memory in a rat model of vascular dementia by increasing VEGF and NR1 in the hippocampus显示文摘Hydroxysafflor yellow A(HSYA) has angiogenesisregulating and neuro-protective effects, but its effects on vascular dementia(VaD) are unknown. In this study, 30 adult Sprague-Dawley rats were randomly allocated to five groups: normal, sham-operation, VaD alone(bilateral carotid artery occlusion), VaD plus saline(control), and VaD plus HSYA. One week after operation, the HSYA group received one daily tail-vein injection of 0.6 mg/100 g HSYA for two weeks. Five weeks after operation, the spatial memory of all five groups was evaluated by the water maze task, and synaptic plasticity in the hippocampus was assessed by the long-term potentiation(LTP) method. Vascular endothelial growth factor(VEGF) and N-methyl-Daspartic acid receptor 1(NR1) expression in the hippocampus was detected via Western blot. We found that, compared with the group with VaD alone, the group with HSYA had a reduced escape latency in the water maze(P <0.05), and the LTP at CA3-CA1 synapses in the hippocampus was enhanced(P <0.05). Western blot in the late-phase VaD group showed slight up-regulation of VEGF and downregulation of NR1 in the hippocampus, while HSYA significantly up-regulated both VEGF and NR1. Theseresults suggested that HSYA promotes angiogenesis and increases synaptic plasticity, thus improving spatial learning and memory in the rat model of VaD.Nan Zhang Mengya Xing Yiyi Wang Hao Liang Zhuo Yang Fudong Shi Yan Cheng 2014Neuroscience Bulletin2014,30,3:30

3Review on supermolecules as chemical drugs显示文摘Supramolecular medicinal chemistry field has been a quite rapidly developing,increasingly active and newly rising interdiscipline which is the new expansion of supramolecular chemistry in pharmaceu-tical sciences,and is gradually becoming a relatively independent scientific area. Supramolecular drugs could be defined as medicinal supermolecules formed by two or more molecules through non-covalent bonds. So far a lot of supermolecules as chemical drugs have been widely used in clinics. Supermolecules as chemical drugs,i.e. supramolecular chemical drugs or supramolecular drugs,which might have the excellences of lower cost,shorter period,higher potential as clinical drugs for their successful research and development,may possess higher bioavailability,better biocompatibility and drug-targeting,fewer multidrug-resistances,lower toxicity,less adverse effect,and better curative effects as well as safety,and therefore exhibit wide potential application. These overwhelming advan-tages have drawn enormous special attention. This paper gives the definition of supramolecular drugs,proposes the concept of supramolecular chemical drugs,and systematically reviews the recent ad-vances in the research and development of supermolecules,including organic and inorganic complex ones as chemical drugs in the area of antitumor,anti-inflammatory,analgesic,antimalarial,antibacterial,antifungal,antivirus,anti-epileptic,cardiovascular agents and magnetic resonance imaging agents and so on. The perspectives of the foreseeable future and potential application of supramolecules as chemical drugs are also presented.ZHOU ChengHe GAN LinLing ZHANG YiYi ZHANG FeiFei WANG GuangZhou JIN Lei GENG RongXia 2009Science China Chemistry2009,52,4:17
4A series of naphthalimide azoles: Design, synthesis and bioactive evaluation as potential antimicrobial agents显示文摘A series of naphthalimide azoles as potential antibacterial and antifungal agents were conveniently and efficiently synthesized starting from commercially available 6-bromobenzo[de]isochromene-1,3-dione. All the new compounds were characterized by NMR, IR, MS and HRMS spectra. Their antimicrobial activities were evaluated against four Gram-positive bacteria, four Gram-negative bacteria and two fungi using two-fold serial dilution technique. The biological assay indicated that most of the prepared compounds exhibited inhibition to the tested strains. In particular, the triazolium derivatives not only gave higher efficacy than their corresponding precursory azoles, but also demonstrated comparable or even better potency than the reference drugs Chloromycin, Orbifloxacin and Fluconazole. Some factors including structural fragments, pH and ClogP values of the target molecules were also preliminarily discussed.DAMU Guri L. V.

Different chiral functional nanomaterials based on liquid-crystalline soft templates, including chiral plasmonic nanomaterials and chiral luminescent nanomaterials, are systematically introduced, and their underlying mechanisms, properties, and potential applications are emphasized. This review concludes with a perspective on the emerging applications, challenges, and future opportunities of such fascinating chiral nanomaterials. This review can not only deepen our understanding of the fundamentals of soft-matter chirality, but also shine light on the development of advanced chiral functional nanomaterials toward their versatile applications in optics, biology, catalysis, electronics, and beyond.Xuan Zhang Yiyi Xu Cristian Valenzuela Xinfang Zhang Ling Wang Wei Feng Quan Li 2022Light(Science & Applications)2022,11,8:6
6Adjuvant treatment for triple-negative breast cancer: a retrospective study of immunotherapy with autologous cytokine-induced killer cells in 294 patients显示文摘Objective: To examine the efficacy and safety of a sequential combination of chemotherapy and autologous cytokine-induced killer(CIK) cell treatment in triple-negative breast cancer(TNBC) patients.Methods: A total of 294 post-surgery TNBC patients participated in the research from January 1, 2009 to January 1, 2015. After adjuvant chemotherapy, autologous CIK cells were introduced in 147 cases(CIK group), while adjuvant chemotherapy alone was used to treat the remaining 147 cases(control group). The major endpoints of the investigation were the disease-free survival(DFS) and overall survival(OS). Additionally, the side effects of the treatment were evaluated.Results: In the CIK group, the DFS and OS intervals of the patients were significantly longer than those of the control group(DFS:P = 0.047;OS: P = 0.007). The multivariate analysis demonstrated that the TNM(tumor-node-metastasis) stage and adjuvant CIK treatment were independent prognostic factors for both DFS [hazard ratio(HR)= 0.520, 95% confidence interval(CI):0.271-0.998, P = 0.049;HR = 1.449, 95% CI:1.118-1.877, P = 0.005, respectively] and OS(HR=0.414, 95% CI:0.190-0.903, P = 0.027;HR= 1.581, 95% CI:1.204-2.077, P = 0.001, respectively) in patients with TNBC. Additionally, longer DFS and OS intervals were associated with increased number of CIK treatment cycles(DFS: P = 0.020;OS: P = 0.040). The majority of the patients who benefitted from CIK cell therapy were relatively early-stage TNBC patients.Conclusion: Chemotherapy in combination with adjuvant CIK could be used to lower the relapse and metastasis rate, thus effectively extending the survival time of TNBC patients, especially those at early stages.Yuhan Zhang Shuaibing Wang Beibei Yang Su Lu Yiyi Du Hong Liu 2019Cancer Biology & Medicine2019,16,2:6
7Economic Life Assessment of Power Transformers Using an Improved Model显示文摘The electric power enterprise devotes considerable attention to the reliability of power transformers particularly when it decides to either maintain these transformers or decommission them altogether from operation.Although this process has reduced the risk of transformer faults,the attendant dilemma is of excessive maintenance of transformers,or retiring them prematurely,leading to high economic waste.This paper is inspired by real-time engineering applications,and proposes an improved model to assess the economic life of power transformers.The new model offers a more efficient approach than previous methods of assessment,with a specific focus of using the annual net income as separate criteria for determining the economic indices of continuous operation,overhaul,and retirement strategies of transformers.The economic life of power transformers is divided into three sections according to different strategies to better resolve the quantification problem in this field.A case study is provided to prove the feasibility and validity of the proposed economic life model.The case study achieves the fine management goal when the electric power enterprise is required to make the maintenance and retirement strategy decision.Jiyu Wang Ruijin Liao Yiyi Zhang Fanjin Meng 2015CSEE Journal of Power and Energy Systems2015,1,3:4
8A Comparison of Different Gracilariopsis lemaneiformis(Rhodophyta) Parts in Biochemical Characteristics, Protoplast Formation and Regeneration显示文摘Gracilariopsis lemaneiformis is a commercially exploited alga. Its filaceous thallus can be divided into three parts, holdfast, middle segment and tip. The growth and branch forming trend and agar content of these three parts were analyzed, respectively, in this study. The results showed that the tip had the highest growth rate and branched most, although it was the last part with branch forming ability. The holdfast formed branches earliest but slowly. Holdfast had the highest agar content. We also assessed the difference in protoplast formation and regeneration among three parts. The middle segment displayed the shortest enzymolysis time and the highest protoplast yield; whereas the tip had the strongest vitality of protoplasts formation. Juvenile plants were only obtained from the protoplasts generated from the tip. These results suggested that the differentiation and function of G. lemaneiformis was different.WANG Zhongxia SUI Zhenghong HU Yiyi ZHANG Si PAN Yulong JU Hongri 2014Journal of Ocean University of China2014,13,4:4
9Phase field modeling of dendrite growth显示文摘Single dendrite and multi-dendrite growth for Al-2 mol pct Si alloy during isothermal solidification are simulated by phase field method. In the case of single equiaxed dendrite growth, the secondary and the necking phenomenon can be observed. For multi-dendrite growth, there exists the competitive growth among the dendrites during solidification. As solidification proceeds, growing and coarsening of the primary arms occurs, together with the branching and coarsening of the secondary arms. When the diffusion fields of dendrite tips come into contact with those of the branches growing from the neighboring dendrites, the dendrites stop growing and being to ripen and thicken.Yutuo ZHANG Chengzhi WANG Dianzhong LI Yiyi LI 2009Acta Metallurgica Sinica(English Letters)2009,22,3:4
10Multi-scale study on the heterogeneous deformation behavior in duplex stainless steel显示文摘The heterogeneous deformation behavior of austenite and ferrite in the 2205 duplex stainless steel was subjected to multiscale analysis based on the in situ synchrotron-based high energy X-ray diffraction,microscopic digital image correlation,electron backscatter diffraction,and transmission electron microscopy.It is found that the heterogeneous deformation triggers from the yielding of austenite.During this deformation stage,austenite experiences greater strain in the area near the phase boundaries because of the impeded function of the phase boundaries to dislocations.Owing to the relatively small difference in hardness between the constituent phases,the strain in austenite grains extends into the adjacent ferrite grains when entering into the ferrite yielding stage.In addition,the strain distribution of the austenite grains is more homogeneous than that of the ferrite grains because of the lower stacking fault energy of austenite,which results in a planar slip,and higher stacking fault energy in case of ferrite,causing cross slip.The interaction between austenite and ferrite becomes considerably obvious when the strain further increases after both constituent phases yielding because of the back stress and forward stress in austenite and ferrite,respectively,which are generated by the pile-up of the geometrically necessary dislocations.Xiao Zhang Pei Wang Dianzhong Li Yiyi Li 2021Journal of Materials Science & Technology2021,,13:3
11Genomic profiling and the impact of MUC19 mutation in hepatoid adenocarcinoma of the stomach显示文摘Dear Editor,Hepatoid adenocarcinoma(HAC)is a rare pathological subtype of extrahepatic tumor,featured by hepatoid differentiation andα-fetoprotein(AFP)-production[1,2].Hepatoid adenocarcinoma of the stomach(HAS),accounting for 0.3%to 1.0%of all gastric cancers(GCs),has attracted increasing attention due to its high degree of malignancy[3].Compared with classic GC,HAS showed a higher rate of vascular invasion,lymph node metastasis,and liver metastasis,with only 9.0%survival rate at 5 years[4].Currently,there is no effective treatment for HAS,and little is known about its pathogenesis.Herein,we investigated the molecular features of HAS and identified potential therapeutic targets for HAS.Mengxuan Zhu Erbao Chen Shan Yu Chen Xu Yiyi Yu Xin Cao Wei Li Pengfei Zhang Yan Wang Baofeng Lian Shuirong Zhang Yueting Qu Lujia Huang Weiwei Shi Yuehong Cui Li Qian Tianshu Liu 2022Cancer Communications2022,42,10:3
12Effect of aging treatment on the microstructures and mechanical properties evolution of 25Cr-20Ni austenitic stainless steel weldments with different Nb contents显示文摘The microstructure evolutions and the mechanical properties of the 25Cr-20Ni austenitic stainless steel weld metals with different Nb contents were investigated during the long term aging treatment at 700~?C.M_(23)C_6,Nb(C,N),α-Cr phase and Nb-nitride phase(Z phase)were observed in the microstructures of the aged weld metals.The results showed that theα-Cr phase precipitated in the interdendritic regions of the weld metals after being exposed to~ 700?C for 500 h and the element Nb accelerated the precipitation of theα-Cr phase significantly.The density of theα-Cr phase decreased with the increase of the distance away from the primary Nb(C,N).Additionally,theα-Cr phase showed a crystallographic relationship with the austenitic matrix,■.It was observed that the Z phase precipitated in the periphery of the Nb(C,N)and may replace the Nb(C,N)after long term exposure to high temperature.The transformation of the Nb(C,N)into Z phase suggested that the Z phase had a higher stability than the Nb(C,N)par^ticles at 700?C for long term aging.The tensile strength of the Nb-bearing weld metal showed a continuous decrease at the initial stage of the aging treatment and then went up slightly with the prolonged aging time.However,the elongations and the impact energies of the weld metals decreased monotonously with the increase of the aging time.Xu Zhang Dianzhong Li Yiyi Li Shanping Lu 2019Journal of Materials Science & Technology2019,35,4:3

14Vapor phase fabrication of three-dimensional arrayed BiI3 nanosheets for cost-effective solar cells显示文摘Multilayered photovoltaic absorbers have triggered widespread attention for their unique structure and properties.However,multilayered materials in the randomly oriented polycrystalline thin-film lead to ineffective carrier transport and collection,which hinders the process of achieving high-performance solar cells.Herein,this issue is tackled by producing the three-dimensional(3D)heterojunction BiI3 nanosheets(NSs)solar cells,which embed vertically aligned monocrystalline BiI3 NSs into spiro-OMeTAD.The preferred orientation of BiI3 NSs and large p-n junction areas of 3D heterojunction structure enable a strong light absorption and effective carrier transport and collection,and thus a power conversion efficiency(PCE)of 1.45%was achieved.Moreover,this PCE is the highest ever reported for BiI3 based solar cells to our best knowledge.Moreover,the nonencapsulated device remained 96%of the initial PCE after 24 h continuous one sun illumination at^70%humidity condition,and 82%of the initial PCE after 1-month storage at^30%humidity condition.Yiyi Zhu Qianpeng Zhang Matthew Kam Swapnadeep Poddar Leilei Gu Shijun Liang Pengfei Qi Feng Miao Zhiyong Fan 2020InfoMat2020,2,5:2
15Spatial patterns of urban green space and its actual utilization status in China based on big data analysis显示文摘Urban green space(UGS)is essential for sustainable urbanization and human well-being.The utilization status of UGS is closely related to the provision of ecosystem services for urban residents.Limitations on data availability,however,have led to the absence of a comprehensive approach for evaluating the actual utilization status of UGS at a large scale.Furthermore,differences in actual UGS utilization between intra-urban and peri-urban areas have not received enough attention.This study used big data analysis by combining point of interest(POI)and land use and cover change(LUCC)to quantify the spatial patterns of UGS utilization,and to evaluate the actual utilization status of UGS in 366 cities on the Chinese mainland.We also explored the differences in the actual utilization of UGS in intra-urban and peri-urban areas.The results showed that 94.01%of UGS resources in China had not been utilized.There was a clear pattern of spatial mismatch between the stock and the actual utilization of UGS,especially in the north-western region indicated by the Hu Huanyong Line.The actual utilization rate of UGS was closely related to the regional develop-ment level.There was a certain mismatch between the actual utilization and stock of intraurban green space(IUGS).The hot spots of the actual utilization rate of IUGS were in Yunnan,Guizhou,and Sichuan Provinces in southwestern China.The differ-ences in UGS actual utilization rates between IUGS and peri-urban green space(PUGS)were small in eastern China,but large in south-western and northwestern China.The actual utilization rate of IUGS in most Chinese cities was significantly larger than that of PUGS,indicating that PUGS were not well utilized.Our results provide scientific support for urban and regional planners in targeting specific areas for UGS design and development,and in optimizing future UGS planning in China.Yiyi Huang Tao Lin Guoqin Zhang Yongguan Zhu Zhiwei Zeng Hong Ye 2021Big Earth Data2021,5,3:2

17Polarization loss analysis and ageing characterisation of transformer oil-immersed insulation by using decoupled frequency domain spectroscopy显示文摘The polarization information contained in the frequency-domain spectroscopy(FDS)could be utilised for characterising the ageing degree of transformer oil-immersed insulation.However,the polarization information will be obscured by its conductance effect,it is thus hard to analyse the polarization behaviour by using the traditional FDS technique.Given this issue,an alternative approach is proposed to analyse the polari-zation information using FDS decoupled by logarithmic-derivative spectroscopy(LDS).Findings proved that the polarization loss information generated by polarization behaviour can be separated from the total dispersion loss.The proposed feature pa-rameters are later used to analyse the polarization loss information under ageing impact.Also,the polarization loss surface is constructed by using these feature parameters to characterise the ageing degrees of oil-immersed samples.Finally,the potential possibility of using the proposed method to analyse the polarization loss and ageing degree are respectively discussed.Xianhao Fan Jiefeng Liu Yiyi Zhang Zheshi Ding Qingyin Wang 2022High Voltage2022,7,3:2
18Effects of surface roughness on interfacial dynamic recrystallization and mechanical properties of Ti-6Al-3Nb-2Zr-1Mo alloy joints produced by hot-compression bonding显示文摘The influence of surface roughness on the interfacial dynamic recrystallization kinetics and mechanical properties of Ti-6 Al-3 Nb-2 Zr-1 Mo hot-compression bonding joints was systematically investigated.It is found that for the bonding interface of rough surfaces,elongated fine grains are formed at the bonding interface due to shear deformation of the interfacial area.As the surface roughness increases,the proportion of elongated grains drastically decreases as they further reorient to form equiaxed grains along the bonding interface of rougher surfaces resulting from severe incompatible deformation of the interface area.Meanwhile,high-density geometrically necessary dislocations accumulate around the interfacial recrystallization area to accommodate the incompatible strain and lattice rotation.A rotational dynamic recrystallization mechanism is thereby proposed to rationalize the formation of fine interfacial recrystallization grains during bonding of rough surfaces.In contrast to that of rough surfaces,bonding interface of polished surfaces exists in the form of straight interface grain boundaries without fine grains under the same deformation conditions.While with the increase of deformation strain,small grain nuclei form along the bonding interface,which is associated with discontinuous dynamic recrystallization assisted by strain-induced boundary migration of interface grain boundaries.Moreover,the bonding joints of rough surfaces show lower elongation compared with that of polished surfaces.This is because the formation of heterogeneous fine grains with low Schmid factor along the bonding interface of rough surfaces,leading to worse compatible deformation capability and thereby poor ductility of bonding joints.Bijun Xie Zhenxiang Yu Haiyang Jiang Bin Xu Chunyang Wang Jianyang Zhang Mingyue Sun Dianzhong Li Yiyi Li 2022Journal of Materials Science & Technology2022,,1:2
19Toripalimab in advanced biliary tract cancer显示文摘Gemcitabine combined with platinum/fluorouracil drugs is the standard firstline treatment for advanced biliary tract cancers(BTCs).We explored the safety and efficacy of toripalimab plus gemcitabine and S-1(GS)as the first-line treatment for advanced BTCs.At a one-sided significance level of 0.025,a total of 50 patients could provide 80%power to show the efficacy at targeted progression-free survival(PFS)rate at 6 months of 70%versus 40%for the combined treatment.This single-arm,phase II study enrolled 50 patients with advanced BTCs who previously received no systemic treatment.The regimen was as follows:toripalimab(240 mg,i.v.,d1),gemcitabine(1,000 mg/m2,i.v.,d1 and d8),and S-1(40–60 mg bid p.o.,d1–14,Q21d).The primary endpoint was progression-free survival.The secondary endpoints included overall survival(OS),objective response rate(ORR),duration of response(DOR),and safety.The associations between response with PDL1 expression,tumor mutational burden(TMB),and genetic variations were explored.Patients were enrolled from January 2019 to August 2020,with a median follow-up time of 24.0 months(IQR:4.3–31.0 months).Wei Li Yueqi Wang Yiyi Yu Qian Li Yan Wang Chenlu Zhang Xiaojing Xu Xi Guo Yu Dong Yuehong Cui Qing Hao Lujia Huang Houbao Liu Tianshu Liu 2022The Innovation2022,3,4:1
