| 2 | Effects of Huatan Tongluo decoction on vascular endothelial growth factor receptor 2 expression in synovial tissues of rats with collagen-induced arthritis显示文摘OBJECTIVE: To determine the therapeutic effect and potential mechanism of Huatan Tongluo decoction on rats with collagen-induced arthritis.METHODS: Forty specific pathogen-free Wistar rats were selected, and 10 were randomly selected as the control(group 1). The remaining rats were injected intradermally with emulsified type Ⅱ bovine collagen at the tail base and back, followed by a booster 7 d post first immunization. After establishing collagen-induced arthritis(CIA), rats were randomly divided into three groups(n = 10). The rats were treated orally for 30 d as follows: group 1, saline; group 2, model(saline); group 3, tripterygium polyglycoside(TP; 7.81 mg/kg, positive control);group 4, Huatan Tongluo decoction(HTTL; 7.5 g/kg). Body weight, ankle swelling and arthritis index were measured over the course of the study. The rats were sacrificed 30 d after treatment. Morphological changes in the synovium were observed by hematoxylin and eosin staining. Pannus formation and synovial thickness in the left ankle were observed by color Doppler ultrasoundVascular endothelial growth factor(VEGF) and VEGFR2 protein levels were measured by immunohistochemistry.VEGF/VEGFR2 mRNA levels were measured by real-time quantitative polymerase chain reaction.RESULTS: Compared with the model group, a significantly lower arthritis index was observed in the positive control group(P < 0.05) and HTTL group(P < 0.01), after treatment. Both positive control and HTTL reduced intra-articular pannus formation and synovial thickening. Furthermore, VEGF mRNA,and VEGFR2 protein and mRNA levels were significantly downregulated(P < 0.05) in the treatment groups.CONCLUSION: Inhibition of the expression of VEGF and VEGFR2 in synovial tissues and the formation of pannus and synovial hyperplasia may be part of the mechanism of HTTL for relieving the symptoms of rheumatoid arthritis in CIA rats. | Chen Jinchun Qiu Mingshan Li Yihan Zhang Qian Zhang Yiyan Lin Shuangjie Zhang Shaohong Qian Lixia Gao Hai Li Liang-cheng | 2019 | Journal of Traditional Chinese Medicine2019，39，2： | 4 |
| 3 | Flame Retardancy of Epoxy Resin/β-cyclodextrin@Resorcinol Bisdiphenylphosphate Inclusion Composites显示文摘In order to improve the efficiency of β-CD,the inclusion complex of β-CD and resorcinol bisdiphenylphosphate (RDP) (β-CD@RDP) was prepared,which β-CD was as the host component and RDP was as the guest.The structure and thermal stability property of β-CD@RDP was also characterized.EP/β-CD@RDP composites were prepared by adding β-CD@RDP into EP matrix.The results of thermogravimetric test showed that the flame retardant systems could effectively increase the corresponding temperature of EP matrix to reach the maximum thermal decomposition rate,and exhibited good char-forming property.When the amount of β-CD@RDP in EP was 20wt%,the limiting oxygen index (LOI) value of EP was increased to 26.5% from 19.8%,and the vertical burning test (UL-94) reached V-1 level.The cone calorimeter test indicated that 20wt% loading in EP could reduce the peak of heat release rate (PHRR) and the total heat release (THR) of EP by 94.7% and 93.4% respectively,and the peak of smoke production rate (PSPR) and the total smoke production (TSP) was reduced by 16.7% and 22.2%,respectively.Therefore,the addition of β-CD@RDP could reduce the fire risk of EP effectively. | SHAN Xueying HAN Ji SONG Yan XING Zhixiang LI Jinchun | 2020 | Journal of Wuhan University of Technology(Materials Science)2020，35，2： | 4 |
| 4 | Synthetic Process of Bio-Based Phenol Formaldehyde Adhesive Derived from Demethylated Wheat Straw Alkali Lignin and Its Curing Behavior显示文摘Lignin is a natural biopolymer with a complex three-dimensional network, commercially obtained from wasteliquid of paper pulp and bioethanol production, and could be a candidate for preparation of environment-friendlybio-based polyphenol material. In the present work, the demethylated wheat straw alkali lignin (D-Lig), preparedby demethylation of wheat straw alkali lignin (Lig) using an in-situ generated Lewis acid, was used to synthesizebio-based phenol formaldehyde resin adhesive (D-LPF) applied in plywood. Effects of synthetic process’s factors,including lignin substitution for phenol, NaOH concentration and molar ratio of formaldehyde to phenol, on thebonding strength and free formaldehyde content of D-LPF were investigated in detail, and the optimum syntheticprocess of D-LPF was obtained as following: Lignin substitution for phenol 60%, NaOH concentration 5.0% andmolar ratio of formaldehyde to phenol 2.0, and under the optimum reaction condition, the D-LPF presented lower free formaldehyde content (0.18%) and higher bonding strength (2.19 MPa), which was better than those ofcontaining-lignin phenol formaldehyde resin adhesive (LPF). Additionally, the curing behavior of the adhesivewas studied by differential scanning calorimetry (DSC) combined with gel time. It can be obtained that D-LPFresin adhesive had the shortest gel time, and fastest curing rate, compared with those of PF and L-PF resin adhesives. The curing kinetics data was fitted well by Kissinger model using non-isothermal DSC method, and theaverage activation energy value was 85.3 kJ/mol, slightly higher than that of commercial PF resin, while lowerthan that of LPF (90.2 kJ/mol). Finally, based on the analytical results of high temperature fourier transform infrared spectroscopy (FTIR), a possible curing mechanism of D-LPF was proposed. | Yan Song Zhixin Wang Xin Zhang Rong Zhang Jinchun Li | 2021 | Journal of Renewable Materials2021，9，5： | 3 |
| 5 | Lifetime prediction of electrical connectors under multiple environment stresses of temperature and particulate contamination显示文摘Electrical connectors play a significant role in the electronic and communication systems.As they are often exposed in the atmosphere environment, it is extremely easy for them to cause electrical contact failure.It is essential to carry out the reliability modeling and predict the lifetime.In the present work, the accelerated lifetime testing method which is on account of the uniform design method was designed to obtain the degradation data under multiple environmental stresses of temperature and particulate contamination for electrical connectors.Based on the degradation data, the pseudo life can be acquired.Then the reliability model was established by analyzing the pseudo life.Accordingly, the reliability function and reliable lifetime function were set up, and the reliable lifetime of the connectors under the multiple environment stresses of temperature and particulate contamination could be predicted for electrical connectors. | Li Qingya Gao Jinchun Xie Gang Jin Qiuyan Ji Rui | 2016 | The Journal of China Universities of Posts and Telecommunications2016，23，5： | 3 |
| 6 | Sort-based relay selection algorithm for decode-and-forward relay system显示文摘In this paper, a sort-based relay selection algorithm is proposed for decode-and-forward wireless relay systems. The proposed algorithm can reduce computational complexity and system overhead in the relay selection for practical decode-and-forward wireless relay systems with multiple sources and multiple relays. This would be a very important improvement. Firstly, the sufficient and necessary conditions for a relay to be feasible to a source are derived. By adopting relay transmission via its feasible relay, the source can improve channel capacity compared to direct transmission. Then, a sort-based relay selection algorithm is proposed based on the sufficient and necessary conditions. In the proposed algorithm, each relay makes decision on its feasibility individually, but the final source-relay paring decision is made in a centralized manner. Simulation results show that the proposed algorithm can provide considerable system performance improvement over the existing algorithm. Especially at low signal-to-noise (SNR) region, the performance of the proposed algorithm almost reaches the optimal one. | XIE Gang LIU YuanAn GAO JinChun LI XingZheng | 2013 | Science China(Information Sciences)2013，56，2： | 1 |
| 7 | Hypoxia-associated circular RNA RPPH1 modulates triple-negative breast cancer cell growth via the miR-1296-5p/TRIM14 axis显示文摘Hypoxia affects the advancement,metastasis,and metabolism of breast cancer(BC).The circular RNA ribonuclease P RNA component H1(circRPPH1)(has_circ_0000515)is implicated in tumor progression.Nevertheless,the regulatory mechanism related to circRPPH1 in hypoxia-mediated triple-negative breast cancer(TNBC)progression is indistinct.The expression levels of circRPPH1,miR-1296-5p,tripartite motif-containing 14(TRIM14)mRNA in tissue samples and cells were examined through quantitative real-time polymerase chain reaction(qRT-PCR).Cell viability,migration,and invasion were determined with Cell Counting Kit-8(CCK-8)or transwell assays.The levels of glucose consumption and lactate production were assessed via the Glucose Assay Kit or Lactate Assay Kit.The protein levels of TRIM14,Glucose Transporter GLUT1(GLUT1),and lactic dehydrogenase A(LDHA)were detected by western blot analysis.The targeting relationship between circRPPH1 or TRIM14 and miR-1296-5p was verified with dual-luciferase reporter assay.The role of circRPPH1 was confirmed via xenograft assay.We verified that circRPPH1 and TRIM14 expression were increased while miR-1296-5p expression was decreased in BC tissues and hypoxia-cultured TNBC cells.Functionally,circRPPH1 silencing reversed the promoting effect of hypoxia on viability,migration,invasion,and glycolysis of TNBC cells.CircRPPH1 knockdown repressed decreased TNBC cell growth in vivo.Mechanistically,circRPPH1 sponged miR-1296-5p to modulate TRIM14 expression.Also,miR-1296-5p silencing restored circRPPH1 inhibition-mediated influence on the viability,migration,invasion,and glycolysis of hypoxia-treated TNBC cells.TRIM14 elevation overturned the inhibitory impact of miR-1296-5p mimic on viability,migration,invasion,and glycolysis of hypoxia-cultured TNBC cells.In conclusion,hypoxia-induced circRPPH1 fostered TNBC progression through regulation of the miR-1296-5p/TRIM14 axis,indicating that circRPPH1 was a promising target for TNBC treatment. | DILIXIATI JINSIHAN DAN LI MINGSHUAI ZHANG JINCHUN FENG QIAN ZHAO | 2021 | BIOCELL2021，45，3： | 1 |
| 8 | Tea Polyphenols Reducing Lipopolysaccharide-induced Inflammatory Responses in RAW264.7 Macrophages via NF-κB Pathway显示文摘The anti-inflammatory activity of tea polyphenols(TPs)in RAW264.7 macrophages stimulated by lipopolysaccharide(LPS)was investigated in this paper.RAW264.7 macrophages were treated with different concentrations of TP(0,12.5,25,50,100,and 200μg/mL)and then stimulated by LPS.Another blank control group was set up.The expression of pro-inflammatory cytokines associated with the nuclear factor-kappa B(NF-κB)signaling pathway was investigated before and after TP treatment.Pretreatment of RAW264.7 cells with TP decreased the expression of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and interleukin 1 beta(IL-1β)pro-inflammatory cytokines.In addition,TP inhibited the phosphorylation of p65 and IκB by blocking the phosphorylation and the degradation of NF-κB inhibitor protein.In conclusion,TP exerts anti-inflammatory effects by regulating the release of inflammatory mediators via the NF-κB signaling pathway. | SU Siyi LI Xiaoyu GUO Xu ZHOU Ruiming LI Manman MING Pengfei HUANG Yingying Sajid Ur RAHMAN DING Hongyan FENG Shibin LI Jinchun WANG Xichun LI Yu WU linjie | 2019 | Chemical Research in Chinese Universities2019，35，6： | 1 |

| 12 | The formation age and evolution of Kumtagh Desert显示文摘The ancient aeolian sand has been regarded as an indicator for the formation and evolution of a desert in the past.Kumtagh Desert is located at the northern fringe of Qinghai-Tibet Plateau.The first integrated scientific investigation to the desert was carried out during the period of 2004-2006.Kumtagh Desert is an ideal natural model for studying the formation and evolution of the desert because the Quaternary strata containing ancient aeolian sands are widely distributed.The integrated field investigation and studies on sedimentary,chronology and palynology of typical profiles named Suosuo gully,Xiaoquan gully and gravel body with ancient aeolian sand layers showed that Kumtagh Desert was probably formed as early as 2,097.7±314.7 ka BP.During the period of 386.9±58.0 ka BP to 285.9±42.9 ka BP,the desert largely expanded and formed its modern distribution pattern.The desert was originally developed in the southwest,subsequently,expanded to the north and northeast.The sedimentary facies of Suosuo gully profile revealed that the desert experienced at least 19 cycles of advance and inverse processes of desertification with an average period of 110 ka in the Quaternary.The neotectonic movements played an important role in the formation,development and geomorphology of the desert.On one hand,the movements caused the formation of intermontane fault basin,which was further developed towards the closed drought basin,and caused the formation of natural environment.On the other hand,under the control of surrounding faults,the unique broom-shaped desert landscape was formed,and the gullies and sand ridges in this region experienced an abrupt directional change from north by west to north by east at the location of 39°45'-39°55'N.The unique landscape of gravel body that occurred widely in the northern desert was formed after 285.9±42.9 ka BP.The results in this paper provide the scientific basis for studying the formation age and evolutionary process under the dry climate and environment in the northwestern China,and the uplifting of Qinghai-Tibet Plateau as well as its responses to the global climate changes. | JinNian TANG ZhiZhu SU Feng DING ShuJuan ZHU YouHao E XinWei ZHAI ZhiYu Yl HuJun LIU JinChun ZHANGI FaMing LI | 2011 | Journal of Arid Land2011，3，2： | 1 |
| 13 | Resource allocation for MIMO-OFDMA downlink based cognitive radio systems with imperfect channel learning显示文摘This paper is concerned with the resource allocation for multiple input multiple output and orthogonal frequency division multiplexing access(MIMO-OFDMA)downlink cognitive radio systems where a cognitive radio MIMO-OFDMA system is under spectrum sharing with an existing primary radio(PR)network.We use the channel learning scheme to estimate the channel information from cognitive radio transmitter(CR-TX)to PR and then make beamforming to transmit signal.Considering the interference from CR-TX to PR caused by the imperfect channel learning,we intend to maximize CR throughput under the interference power constraint at PR and CR transmit power constraint.A nearly optimal subcarrier and power allocation algorithm with linear complexity is proposed.The proposed algorithm is global optimal when the maximum transmit power is beyond certain threshold.Simulation results show that the proposed algorithm has a good performance very close to the global optimal algorithm. | LI XiuWen GAO JinChun LIU YuanAn XIE Gang MAO JunLing DENG PanLiang | 2013 | Science China(Information Sciences)2013，56，10： | 0 |

| 15 | MiR-520f-3p inhibits epithelial-mesenchymal transition of colorectal cancer cells by targeting Yes-associated protein 1显示文摘Background:Colorectal cancer(CRC)is one of the most common malignancies.Early diagnosis is the key to effective treatment of CRC.Since microRNAs(miRNAs)can be used as biomarkers of CRC,the objective of this work was to examine the effect of miR-520f-3p,which targets YAP1(Yes-associated protein 1),on the ability of CRC cells to proliferate,invade,migrate,and undergo epithelial-mesenchymal transition(EMT).Methods:A miR-520f-3p mimic was used to overexpress miR-520f-3p in HT29 cells.To establish the tumor-bearing mouse model,transfected HT29 cells were subcutaneously implanted into BALB/c-nu nude mice,and YAP1 and miR-520f-3p levels were determined using qRT‒PCR.The viability,invasion ability,and migration ability of cells were evaluated by CCK-8,Transwell,and wound healing assays.Apoptosis was detected by flow cytometry and TUNEL assays.The regulatory link between miR-520f-3p and the YAP1 gene was examined by dual-luciferase reporter assay.Tumor tissues with positive Ki-67 expression were identified by immunohistochemistry.Vimentin,E-cadherin,and YAP1 expression were evaluated by western blotting.Results:MiR-520f-3p overexpression could inhibit proliferation,invasion,migration,and EMT and induce apoptosis in HT29 cells.YAP1 was found as a target of miR-520f-3p.The inhibitory effects of miR-520f-3p on proliferation,invasion,migration,and EMT may be reversed by overexpressing YAP1.In tumor-bearing mice,miR-520f-3p overexpression reduced the Ki-67 level,increased apoptosis,and prevented tumor development and spread.Conclusion:By targeting YAP1,miR-520f-3p may be capable of suppressing CRC cell proliferation,invasion,migration,and EMT,providing a novel therapeutic target for the disease. | LIJUN JIANG WENMIN JI YAJIE GONG JIAJUN LI JINCHUN LIU | 2023 | BIOCELL2023，47，8： | 0 |
| 16 | Diamond synthesis from a system of chromium-carbide andNi_(70)Mn_(25)Co_5 alloy显示文摘In order to ascertain the mechanism of interaction between carbide and metallic catalyst and formation of diamond under high pressure and high temperature, and find a new method to synthesize diamond with special properties, it is necessary to investigate the reaction behavior of different carbides and metallic solvent_catalysts under high pressure and high temperature. A system of Cr-3C-2 powder and Ni 70Mn 25Co 5 alloy in weight ratio of 1∶6 was treated under 6 0 GPa and 1 500℃ for 20, 30 or 60 min respectively. X_ray diffraction of the samples indicated the Cr 3C 2 decomposed partially after high pressure and temperature treatment, and Cr 7C 3, Cr and diamond formed respectively. There was not any trace of graphite in the samples. The result suggested that the separated carbon atoms could form diamond directly without conversion process of graphite into diamond. The observation of SEI, WDX and EDX also showed that diamond crystals were synthesized in the system, which have perfect surfaces and shapes, with the average grain size of about 40 μm. The properties of the crystals are being investigated. | LI Liangbin 1, JIANG Jinchun 1, HONG Shiming 1, ZHONG Yumao 2 and ZHANG Xinyuan 2 1.

| 17 | TMAHS:a truthful multi-unit double auction framework for heterogeneous spectrum in secondary market显示文摘Auction was widely used to tackle spectrum allocation and sharing in the secondary market under the condition of spectrum scarcity. In real communication system, such as broadband communication, the utilization of spectrum resource is various because of different requirements and complex application scenarios. So, these schemes cannot be directly applied to the above wireless communication system. To solve this problem, a new model where sellers/buyers can sell/buy multi-unit for heterogeneous spectrum was proposed and a truthful multi-unit double auction framework was designed for heterogeneous spectrum trading. A valuation function is first applied to represent the buyer's true valuation of the sub-band and reflect the buyer's satisfaction degree and a novel concept termed ‘virtual player' was introduced. Then the buyer group was constructed based on the conflict graph to reuse the same spectrum among interference-free buyers in both spatial and temporal domains. The winner determination strategy and algorithm of clearing price were designed elaborately. According to the theoretical analysis, the scheme can satisfy three critical economic properties: truthfulness, individual rationality, and budget balance. Finally, simulation results show that the proposed scheme can achieve better user satisfaction, auction efficiency and spectrum reuse rate for the real communication system. The proposed auction framework is practical and effective. | Li Xin Xie Gang Gao Jinchun | 2019 | The Journal of China Universities of Posts and Telecommunications2019，26，1： | 0 |
| 18 | Measuring observability by generalized information theoretic quantities显示文摘A normalized measure is established to provide the quantitative information about the degree of observabil-ity for the discrete-time,stochastically autonomous system. This measure is based on the generalized information theoretic quantities (generalized entropy,mutual information) of the system state and the observations,where the system state can be a discrete or a continuous random vector. Some important properties are presented. For the linear case,the explicit formula for the degree of observability is derived,and the equivalence between the proposed measure and the traditional rank condition is proved. The curves for the degree of observability are depicted in a simple example. | Badong CHEN Jinchun HU Hongbo LI Zengqi SUN | 2008 | 控制理论与应用(英文版)2008，6，3： | 0 |
| 19 | Effects of electrode immersion depth and remelting rate on electroslag remelting process显示文摘In the electroslag remelting process, the electrode molten state is a critical factor determining the ingot quality, while the electrode immersion depth and melting rate are key factors for the stability of the electroslag re-melting process. Studies were carried out to investigate the microscopic and macroscopic effects of electrode immersion depth and melting rate on the potential distribution and heat density in the slag bath, and on the depth and shape of the molten bath. Based on the finite element method and the numerical solution method, the effect of the electrode immersion depth on the slag bath heat density was researched; the relationship between the electrode immersion depth and the slag resistance was obtained; and the unsteady-state model of the solidification process of the re-melting ingot was solved using the finite difference method. The mathematical model and physical model of the electrode melting process were established and solved; and the corresponding curves between the electrode molten-state and slag-bath physical parameters were obtained. The experimental results verified the simulated results studied in this paper. | Song Jinchun Wang Changzhou Li Song | 2014 | China Foundry2014，11，3： | 0 |
