| 1 | Thrombin is a therapeutic target for non-small-cell lung cancer to inhibit vasculogenic mimicry formation显示文摘Tumor cells transform into endothelial cells by epithelial-to-mesenchymal transition,which is characterized by vasculogenic mimicry(VM).VM not only accelerates tumor progression but also increases drug-induced resistance.However,very little is currently known about the molecular determinants that enable VM.Targeting VM might bring a new breakthrough in cancer treatment.Thrombin is the key enzyme of the blood coagulation system and could contribute to tumor progression.Nevertheless,the association between thrombin and VM formation remains largely unknown.We found that VM was associated with the overall survival of non-small-cell lung cancer(NSCLC)patients,and that thrombin expression was closely related to VM formation.This research revealed that thrombin induced VM formation via PAR-1-mediated NF-κB signaling cascades.The novel thrombin inhibitors r-hirudin and DTIP inhibited VM formation and spontaneous metastases in subcutaneous tumors.Clinical pathological analysis confirmed that NSCLC patients with thrombin-positive/PAR-1-high expression had the poorest prognosis and were the most likely to form VM.The promotional activity of thrombin in VM formation and tumor metastasis was abolished in PAR-1-deficient NSCLC cells.The EGFR inhibitor gefitinib had no effect on VM and increased VEGF expression in tumors.The combination therapy of DTIP and gefitinib achieved a better therapeutic effect than either agent alone.This study is the first to illustrate that thrombin substantially contributes,together with PAR-1,to VM formation and to illustrate that VM might be a target of r-hirudin and DTIP to suppress tumor progression.The anticoagulants r-hirudin and DTIP could be employed for antitumor therapy.Combination therapy with DTIP with an EGFR inhibitor might achieve superior therapeutic effects. | Bing Zhao Mengfang Wu Zhihuang Hu Yixin Ma Wang Qi Yanling Zhang Yaran Li Min Yu Huijie Wang Wei Mo | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 2 |
| 2 | Effects of Pore-forming Agents on Properties of Silicon Carbide Porous Ceramics Prepared from Crystalline Silicon Cutting Waste显示文摘SiC powder was rapidly synthesized in an induction furnace with crystalline silicon cutting waste and active carbon as raw materials,and then SiC porous ceramics were prepared at 1600 t for 4 h with carbon embedded using the powder as raw material,the starch and the graphite as pore-forming agents.Effects of additions of different pore-forming agents on the phase composition,microstructures,physical properties,and cold crushing strength of the porous ceramics were investigated.The results show that the main crystalline phases of the synthetic powder areα-S iC(6H-SiC)andβ-SiC(3C-SiC).The phase composition of the porous ceramics includesα-S iC(6H-SiC),β-SiC(3C-SiC),FeSi,quartz and Si2N20.The apparent porosity and closed porosity of the porous ceramics prepared by adding starch are higher,and the cold compressive strength of the porous ceramics added with graphite is higher.As increasing the additions of the starch,the apparent porosity,closed porosity and linear shrinkage ratio of the porous ceramics increase,and the bulk density decreases correspondingly.When 20 mass%starch is added,the apparent porosity,closed porosity,linear shrinkage ratio and cold compressive strength are 57.05%,2.03%,5.10%and 10.20 MPa,respectively. | MA Beiyue WU Hua GAO Zhi REN Xinming ZHANG Yaran | 2019 | China's Refractories2019，28，4： | 1 |

| 5 | Design and fabrication of r-hirudin loaded dissolving microneedle patch for minimally invasive and long-term treatment of thromboembolic disease显示文摘Cardiovascular disease is the leading cause of global mortality,with anticoagulant therapy being the main prevention and treatment strategy.Recombinant hirudin(r-hirudin)is a direct thrombin inhibitor that can potentially prevent thrombosis via subcutaneous(SC)and intravenous(IV)administration,but there is a risk of haemorrhage via SC and IV.Thus,microneedle(MN)provides painless and sanitary alternatives to syringes and oral administration.However,the current technological process for the micro mould is complicated and expensive.The micro mould obtained via three-dimensional(3D)printing is expected to save time and cost,as well as provide a diverse range of MNs.Therefore,we explored a method for MNs array model production based on 3D printing and translate it to micro mould that can be used for fabrication of dissolving MNs patch.The results show that r-hirudin-loaded and hyaluronic acid(HA)-based MNs can achieve transdermal drug delivery and exhibit significant potential in the prevention of thromboembolic disease without bleeding in animal models.These results indicate that based on 3D printing technology,MNs combined with r-hirudin are expected to achieve diverse customizableMNs and thus realize personalized transdermal anticoagulant delivery for minimally invasive and long-term treatment of thrombotic disease. | Mengfang Wu Tian Xia Yaran Li Tianfa Wang Shijia Yang Jinchao Yu Qiaoyan Liang Teng Shen Min Yu Bing Zhao | 2022 | Asian Journal of Pharmaceutical Sciences2022，17，2： | 1 |
| 6 | The calculation and optimal allocation of transmission capacity in natural gas networks with MINLP models显示文摘The transmission capacity of gas pipeline networks should be calculated and allocated to deal with the capacity booking with shippers. Technical capacities, which depend on the gas flow distribution at routes or interchange points, are calculated with a multiobjective optimization model and form a Pareto solution set in the entry/exit or point-to-point regime. Then, the commercial capacities, which can be directly applied in capacity booking, are calculated with single-objective optimization models that are transformed from the above multiobjective model based on three allocation rules and the demand of shippers.Next, peak-shaving capacities, which are daily oversupply or overdelivery amounts at inlets or deliveries,are calculated with two-stage transient optimization models. Considering the hydraulic process of a pipeline network and operating schemes of compressor stations, all the above models are mixed-integer nonlinear programming problems. Finally, a case study is made to demonstrate the ability of the models. | Yaran Bu Changchun Wu Lili Zuo Qian Chen | 2023 | Chinese Journal of Chemical Engineering2023，59，7： | 0 |
| 7 | Dynamic covalent nano-networks comprising antibiotics and polyphenols orchestrate bacterial drug resistance reversal and inflammation alleviation显示文摘New antimicrobial strategies are urgently needed to meet the challenges posed by the emergence of drug-resistant bacteria and bacterial biofilms.This work reports the facile synthesis of antimicrobial dynamic covalent nano-networks(aDCNs)composing antibiotics bearing multiple primary amines,polyphenols,and a cross-linker acylphenylboronic acid.Mechanistically,the iminoboronate bond drives the formation of aDCNs,facilitates their stability,and renders them highly responsive to stimuli,such as low pH and high H2O2 levels.Besides,the representative A1B1C1 networks,composed of polymyxin B1(A1),2-formylphenylboronic acid(B1),and quercetin(C1),inhibit biofilm formation of drug-resistant Escherichia coli,eliminate the mature biofilms,alleviate macrophage inflammation,and minimize the side effects of free polymyxins.Excellent bacterial eradication and inflammation amelioration efficiency of A1B1C1 networks are also observed in a peritoneal infection model.The facile synthesis,excellent antimicrobial performance,and biocompatibility of these aDCNs potentiate them as a much-needed alternative in current antimicrobial pipelines. | Yuanfeng Li Yin-Zi Piao Hua Chen Keqing Shi Juqin Dai Siran Wang Tieli Zhou Anh-Tuan Le Yaran Wang Fan Wu Rujiang Ma Linqi Shi Yong Liu | 2023 | Bioactive Materials2023，，9： | 0 |
| 8 | Ultra-thin temperature controllable microwell array chip for continuous real-time high-resolution imaging of living single cells显示文摘Single-cell imaging,a powerful analytical method to study single-cell behavior,such as gene expression and protein profiling,provides an essential basis for modern medical diagnosis.The coding and localization function of microfluidic chips has been developed and applied in living single-cell imaging in recent years.Simultaneously,chip-based living single-cell imaging is also limited by complicated trapping steps,low cell utilization,and difficult high-resolution imaging.To solve these problems,an ultra-thin temperature-controllable microwell array chip(UTCMA chip)was designed to develop a living single-cell workstation in this study for continuous on-chip culture and real-time high-resolution imaging of living single cells.The chip-based on ultra-thin ITO glass is highly matched with an inverted microscope(or confocal microscope)with a high magnification objective(100×oil lens),and the temperature of the chip can be controlled by combining it with a home-made temperature control device.High-throughput single-cell patterning is realized in one step when the microwell array on the chip uses hydrophilic glass as the substrate and hydrophobic SU-8 photoresist as the wall.The cell utilization rate,single-cell capture rate,and microwell occupancy rate are all close to 100%in the microwell array.This method will be useful in rare single-cell research,extending its application in the biological and medical-related fields,such as early diagnosis of disease,personalized therapy,and research-based on single-cell analysis. | Yuanyuan Wu Lei Zhao Yaran Chang Liang Zhao Guangsheng Guo Xiayan Wang | 2021 | Chinese Chemical Letters2021，32，11： | 0 |
