3Salvianolic acid A alleviates renal injury in systemic lupus erythematosus induced by pristane in BALB/c mice显示文摘The purpose of this study was to investigate the effects of salvianolic acid A(SAA) in systemic lupus erythematosus(SLE) induced by pristane in BALB/c mice.Lupus mice were established by confirming elevated levels of autoantibodies and IL-6 after intraperitoneal injection of pristane.Mice were then treated with daily oral doses of SAA for 5 months in parallel with mice treated with prednisone and aspirin as positive controls.The levels of autoantibodies were monitored at monthly intervals and nephritic symptoms observed by hematoxylin and eosin(H&E) and periodic acid-Schiff(PAS) staining.Western blot analysis of renal tissue was also employed.SAA treatment caused a significant reduction in the levels of anti-Sm autoantibodies and reduced renal histopathological changes and pathological effects.SAA treatment also significantly inhibited the phosphorylation of IKK,IκB and NFκB in renal tissues of lupus mice.In conclusion,the results suggest that SAA alleviates renal injury in pristane-induced SLE in BALB/c mice through inhibition of phosphorylation of IKK,IκB and NFκB.Yihuang Lin Yu Yan Huifang Zhang Yucai Chen Yangyang He Shoubao Wang Lianhua Fang Yang Lv Guanhua Du 2017Acta Pharmaceutica Sinica B2017,7,2:8

5The Chinese carbon cycle data-assimilation system(Tan-Tracker)显示文摘In this study,the Chinese carbon cyle dataassimilation system Tan-Tracker is developed based on the atmospheric chemical transport model(GEOS-Chem)platform.Tan-Tracker is a dual-pass data-assimilation system in which both CO2concentrations and CO2fluxes are simultaneously assimilated from atmospheric observations.It has several advantages,including its advanced data-assimilation method,its highly efficient computing performance,and its simultaneous assimilation of CO2concentrations and CO2fluxes.Preliminary observing system simulation experiments demonstrate its robust performance with high assimilation precision,making full use of observations.The Tan-Tracker system can only assimilate in situ observations for the moment.In the future,we hope to extend Tan-Tracker with functions for using satellite measurements,which will form the quasioperational Chinese carbon cycle data-assimilation system.Xiangjun Tian Zhenghui Xie Zhaonan Cai Yi Liu Yu Fu Huifang Zhang 2014Chinese Science Bulletin2014,59,14:7
6Trajectory tracking control of a bionic robotic fish based on iterative learning显示文摘A bionic robotic fish has great potential application prospect.High maneuverability swimming control of a bionic robotic fish has been one of the research hotspots in the robotic fish field.In this paper,an iterative learning method has been proposed to solve the trajectory tracking control problem of robotic fish swimming.First,a dynamic model of the multi-joint bionic robotic fish is established.By considering a three-joint robotic fish as an example,the unified expression of the dynamic equation of the three-joint bionic robotic fish is obtained by Lagrange method.Second,the iterative learning controller for controlling the bionic robotic fish is designed.Then the convergence of the iterative learning controller is proved.Finally,the trajectory tracking control simulation experiment based on iterative learning is conducted.The simulation results show that the trajectory tracking control method based on iterative learning for a bionic robotic fish is effective.Ming WANG Yanlu ZHANG Huifang DONG Junzhi YU 2020Science China(Information Sciences)2020,63,7:7
7Rescue of premature aging defects in Cockayne syndrome stem cells by CRISPR/Cas9-mediated gene correction显示文摘Cockayne syndrome(CS)is a rare autosomal recessive inherited disorder characterized by a variety of clinical features,including increased sensitivity to sunlight,progressive neurological abnormalities,and the appearance of premature aging.However,the pathogenesis of CS remains unclear due to the limitations of current disease models.Here,we generate integration-free induced pluripotent stem cells(iPSCs)from fibroblasts from a CS patient bearing mutations in CSB/ERCC6 gene and further derive isogenic genecorrected CS-iPSCs(GC-iPSCs)using the CRISPR/Cas9 system.CS-associated phenotypic defects are recapitulated in CS-iPSC-derived mesenchymal stem cells(MSCs)and neural stem cells(NSCs),both of which display increased susceptibility to DNA damage stress.Premature aging defects in CS-MSCs are rescued by the targeted correction of mutant ERCC6.We next map the transcriptomic landscapes in CS-iPSCs and GC-iPSCs and their somatic stem cell derivatives(MSCs and NSCs)in the absence or presence of ultraviolet(UV)and replicative stresses,revealing that defects in DNA repair account for CS pathologies.Moreover,we generate autologous GC-MSCs free of pathogenic mutation under a cGMP(Current Good Manufacturing Practice)-compliant condition,which hold potential for use as improved biomaterials for future stem cell replacement therapy for CS.Collectively,our models demonstrate novel disease features and molecular mechanisms and lay a foundation for the development of novel therapeutic strategies to treat CS.Si Wang Zheying Min Qianzhao Ji Lingling Geng Yao Su Zunpeng Liu Huifang Hu Lixia Wang Weiqi Zhang Keiichiro Suzuiki Yu Huang Puyao Zhang Tie-Shan Tang Jing Qu Yang Yu Guang-Hui Liu Jie Qiao 2020Protein & Cell2020,11,1:7

9Improved oxygen reduction reaction via a partially oxidized Co-CoO catalyst on N-doped carbon synthesized by a facile sand-bath method显示文摘High active and durable non-noble metal electrocatalysts are urgently developed to satisfy the high performance oxygen reduction reaction(ORR). We successfully synthesized Co-CoOx anchored on nitrogen-doped carbon via a facile sand-bath method(SBM), i.e., Co-CoOx/N-C(SBM). The as-obtained Co-CoOx/N-C(SBM) exhibited overwhelming superiorities to Co-CoO/N-C prepared by conventional heat treatment(CHT), particularly in electrochemical performance of ORR. Although Co-CoOx/N-C(SBM)showed smaller specific surface area of 276.8 m^2/g than that of 939.5 m^2/g from Co-CoO/N-C(CHT), the Co-CoOx/N-C(SBM) performed larger pore diameter and more Co_3O_4 active component resulting in better ORR performance in 0.1 mol/L KOH solution. The Co-CoO_x/N-C(SBM) delivered onset potential of 0.91 V vs. RHE, mid-wave potential of 0.85 V vs. RHE and limited current density of 5.46 mA/cm^2 much better than those of the Co-CoO/N-C(CHT). Furthermore, Co-CoOx/N-C(SBM) showed greater stability and better methanol tolerance superior to the commercial 20 wt% Pt/C.Libing Hu Feng Yu Huifang Yuan Gang Wang Mincong Liu Lina Wang Xueyan Xue Banghua Peng Zhiqun Tian Bin Dai 2019Chinese Chemical Letters2019,30,3:4
10Defective ZnS nanoparticles anchored in situ on N-doped carbon as a superior oxygen reduction reaction catalyst显示文摘Defect engineering has been used to develop low-cost and effective catalysts to boost oxygen reduction reactions.However,the development of catalysts that use metal cation vacancies as the active sites for oxygen reduction reaction is lacking.In this study,ZnS nanoparticles on N-doped carbon serve as an oxygen reduction reaction catalyst.These catalysts were prepared via a one-step method at 900℃.Amazingly,the high-resolution transmission electron microscope image revealed obvious defects in the ZnS nanoparticles.These facilitated the catalyst synthesis,and the product displayed good electrocatalytic performance for the oxygen reduction reaction in an alkaline medium,including a lower onset potential,lower mid-wave potential,four electron transfer process,and better durability compared with 20 wt%Pt/C.More importantly,the density functional theory results indicated that using the Zn vacancies in the prepared catalyst as active sites required a lower reaction energy to produce OOH*from*OO toward oxygen reduction reaction.Therefore,the proposed catalyst with Zn vacancies can be used as a potential electrocatalyst and may be substitutes for Pt-based catalysts in fuel cells,given the novel catalyst’s resulting performance.Libing Hu Zengxi Wei Feng Yu Huifang Yuan Mincong Liu Gang Wang Bangfiua Peng Bin Dai Jianmin Ma 2019Journal of Energy Chemistry2019,28,12:3
11Single-cell transcriptomic profiling unravels the adenoma-initiation role of protein tyrosine kinases during colorectal tumorigenesis显示文摘The adenoma-carcinoma sequence is a well-accepted roadmap for the development of sporadic colorectal cancer.However,cellular heterogeneity in aberrant epithelial cells limits our understanding of carcinogenesis in colorectal tissues.Here,we performed a single-cell RNA sequencing survey of 54,788 cells from patient-matched tissue samples,including blood,normal tissue,para-cancer,polyp,and colorectal cancer.Xiaobo Zheng Jinen Song Chune Yu Zongguang Zhou Xiaowei Liu Jing Yu Guangchao Xu Jiqiao Yang Xiujing He Xin Bai Ya Luo Yu Bao Huifang Li Lie Yang Mingqing Xu Nan Song Xiaodong Su Jie Xu Xuelei Ma Hubing Shi 2022Signal Transduction and Targeted Therapy2022,7,3:2
12Enhanced oxygen reduction reaction performance of Co@N–C derived from metal-organic frameworks ZIF-67 via a continuous microchannel reactor显示文摘Traditional methods of preparing metal-organic frameworks(MOFs)compounds have the disadvantages such as poor dispersion,inefficient and discontinuous process.In this work,microchannel reactor is used to prepare MOFs-derived zeolite-imidazole material via flash nanoprecipitation to form ZIF-67+PEI(FNP),which reduces the MOF synthesis time down to millisecond time interval while keeping the synthesized ZIF-67+PEI(FNP)highly dispersed.The Co@N–C(FNP)catalyst obtained by flash nanoprecipitation and carbonization has a higher Co content and thus more active sites for oxygen reduction reaction than the Co@N–C(DM)catalyst prepared by direct mixing method.Electrochemical tests show that the Co@N–C(FNP)catalyst prepared by this method has excellent oxygen reduction performance,good methanol resistance and high stability.The onset potential and half-wave potential of Co@N–C(FNP)are 0.92 VRHE and 0.83 VRHE,respectively,which are higher than that of Co@N–C(DM)(Eonset=0.90 VRHEand E1/2=0.83VRHE).Moreover,the Zn-air battery assembled with Co@N–C(FNP)as the cathode catalyst has high open circuit voltage,high power density and large specific capacity.The performance of these batteries has been comparable to that of Pt/C assembled batteries.Density functional theory(DFT)calculations confirm that the Co(220)crystal plane present in Co@N–C(FNP)have stronger adsorption energy than that of Co(111)crystal plane in Co@N–C(DM),leading to better electrocatalytic performance of the former.Chenxu Wang Huifang Yuan Feng Yu Jie Zhang Yangyang Li Wentao Bao Zhimou Wang Ke Lu Jie Yu Ge Bai Gang Wang Banghua Peng Lili Zhang 2023Chinese Chemical Letters2023,34,1:2

15A Weighted Threshold Secret Sharing Scheme for Remote Sensing Images Based on Chinese Remainder Theorem显示文摘The recent advances in remote sensing and computer techniques give birth to the explosive growth of remote sensing images.The emergence of cloud storage has brought new opportunities for storage and management of massive remote sensing images with its large storage space,cost savings.However,the openness of cloud brings challenges for image data security.In this paper,we propose a weighted image sharing scheme to ensure the security of remote sensing in cloud environment,which takes the weights of participants(i.e.,cloud service providers)into consideration.An extended Mignotte sequence is constructed according to the weights of participants,and we can generate image shadow shares based on the hash value which can be obtained from gray value of remote sensing images.Then we store the shadows in every cloud service provider,respectively.At last,we restore the remote sensing image based on the Chinese Remainder Theorem.Experimental results show the proposed scheme can effectively realize the secure storage of remote sensing images in the cloud.The experiment also shows that no matter weight values,each service providers only needs to save one share,which simplifies the management and usage,it also reduces the transmission of secret information,strengthens the security and practicality of this scheme.Qi He Shui Yu Huifang Xu Jia Liu Dongmei Huang Guohua Liu Fangqin Xu Yanling Du 2019Computers, Materials & Continua2019,,2:2
16Efficacy of Sanqi(Radix Notoginseng)in treating cerebral hemorrhage in rats with traumatic brain injury显示文摘OBJECTIVE:To evaluate the protective efficacy of Sanqi(Radix Notoginseng)on cerebral hemorrhage in a rat model of traumatic brain injury(TBI)by investigating plasminogen activator inhibitor-1(PAI-1),tissue-type plasminogen activator(t-PA),nuclear factor-κB(NF-κB,p-p65),nitric oxide(NO),endothelin(ET),cluster differentiation(CD61CD62),and coagulation.METHODS:The free-fall method was used to create a rat model of TBI.Forty-eight rats were randomly divided into six groups:the blank group,sham group,model group,low-dose Sanqi(Radix Notoginseng)group,middle-dose Sanqi(Radix Notoginseng)group,and high-dose Sanqi(Radix Notoginseng)group.At 24 h after the model was created,we investigated brain MRI,brain tissue morphology using HE staining,flow cytometry,and immunohistochemical changes.RESULTS:Cerebral hemorrhage was aggravated in TBI rats(observed in brain specimens,brain MRI,and brain tissue HE).Cerebral immunohistochemistry results demonstrated that the expression of t-PA,PAI-1 and p-p65 increased significantly in TBI rats,while t-PA/PAI-1 had a significant decrease.In addition,CD61CD62,D2D,and ET were significantly increased in TBI rats,and PT and APTT were significantly prolonged;in contrast,NO was significantly decreased.Sanqi(Radix Notoginseng)decreased cerebral hemorrhage in TBI rats(observed in brain MRI and brain tissue HE),and increased t-PA/PAI-1,CD61CD62 significantly.It also significantly decreased the expression of t-PA,PAI-1,and p-p65 in brain immunohistochemistry and significantly decreased PT,APTT,D2D,and ET.However,there were no differences in NO between the model group and the Sanqi(Radix Notoginseng)group.CONCLUSION:Sanqi(Radix Notoginseng)can decrease the expression of p-p65,increase t-PA/PAI-1,and stem traumatic intracranial hemorrhage in a TBI rat model.JIANG Tao ZHOU Xiaqing JIANG Huifang YING Rongbiao ZHANG Zhirong CAI Danli WU Yu FANG Haijun WANG Lingcong 2021Journal of Traditional Chinese Medicine2021,41,2:2
17Clinical observation of Yiqi Qingdu Prescription(益气清毒方)on the treatment of intermediate-stage and advanced non-small-cell lung cancer显示文摘OBJECTIVE:To observe the effects of the Yiqi Qingdu prescription(益气清毒方)on intermediate-stage and advanced non-small-cell lung cancer(NSCLC).METHODS:In total,300 patients with intermediate-stage or advanced NSCLC were randomly and equally divided into three groups using computer-generated random numbers as follows:Western medicine(WM),Chinese medicine(CM),and integrated Traditional Chinese and Western Medicine(IM).After 3 months of treatment,the overall response rate(ORR);disease control rate(DCR);symptom score(SS);Karnofsky performance status(KPS);adverse event score;counts of CD3^(+),CD4^(+),and CD8^(+)cells;CD4^(+)/CD8^(+)ratio;and carcinoembryonic antigen(CEA)level were compared among the groups.RESULTS:The ORRs were 30.36%,20.24%,and 7.87%in the IM,CM,and WM groups,respectively,whereas the DCRs were 85%,75%,and 73%,respectively.Compared to the CM group,the ORR was significantly higher in the WM and IM groups,whereas the DCR was significantly higher in the IM group(all P<0.05).SS was obviously higher in the WM group than in the other two groups(both P<0.01).KPS was significantly lower in the WM group after treatment(P=0.005).The mean number of adverse events was significantly lower in the CM(2.2±1.3)and IM(2.4±1.3)groups than in the WM group(4.6±1.7,both P<0.05).CD3^(+)cell counts were significantly decreased in the WM group(P=0.031).In the IM group,CD8^(+)cell counts were increased after treatment,whereas the CD4^(+)/CD8^(+)ratio was decreased(both P<0.01).Compared with the WM group,CD3^(+)(P=0.01),CD4^(+)(P=0.044),and CD8^(+)(P=0.009)cell counts were significantly higher in the IM group,whereas the CD4^(+)/CD8^(+)ratio was significantly lower(P=0.011).Relative to the CM group,CD8^(+)cell counts were significantly higher(P=0.001)and the CD4^(+)/CD8^(+)ratio was significant ly lower in the IM group(P=0.001).CEA levels were significantly increased in the CM group(P=0.023).CONCLUSION:The Yiqi Qingdu prescription can improve the outcomes of WM in patients with NSCLC.LIANG Qijun TANG Xiaoling YU Jiong XIONG Monian ZHU Huifang XIONG Linkai ZENG Ru YU Peiwen 2021Journal of Traditional Chinese Medicine2021,41,2:2

19Post-quantum blind signcryption scheme from lattice显示文摘Blind signcryption(BSC) can guarantee the blindness and untrackability of signcrypted messages, and moreover, it provides simultaneous unforgeability and confidentiality. Most traditional BSC schemes are based on the number theory. However, with the rapid development of quantum computing, traditional BSC systems are faced with severe security threats. As promising candidate cryptosystems with the ability to resist attacks from quantum computing, lattice-based cryptosystems have attracted increasing attention in academic fields. In this paper, a post-quantum blind signcryption scheme from lattice(PQ-LBSCS) is devised by applying BSC to lattice-based cryptosystems. PQ-LBSCS inherits the advantages of the lattice-based cryptosystem and blind signcryption technique. PQ-LBSCS is provably secure under the hard assumptions of the learning with error problem and small integer solution problem in the standard model. Simulations are carried out using the Matlab tool to analyze the computational efficiency, and the simulation results show that PQ-LBSCS is more efficient than previous schemes. PQ-LBSCS has extensive application prospects in e-commerce, mobile communication, and smart cards.Huifang YU Lu BAI 2021Frontiers of Information Technology & Electronic Engineering2021,22,6:1
