| 1 | Revenue-sharing contract to coordinate independent participants within the supply chain显示文摘To improve the performance of the supply chain with one supplier and multiple retailers under deter- ministic price-sensitive customer demand,an optimal strategy is proposed based on knowledge discovery.First the decentralized system in which the supplier and the retailers are independent,profit-maximizing participants with the supplier acting as a Stackelberg game leader is studied.Numerical examples illustrate the importance of the coordination.The conventional quantity discount mechanism needs to be modified to coordinate the supply chain, so a revenue-sharing contract is proposed to coordinate such supply chain.Lastly,a special decision under certain demand rates is studied.The pricing and replenishment policies can be decided sequentially,which yields much less loss comparing with optimal decision when the demand rates are sufficiently large. | Chen Kebing Gao Chengxiu Wang Yan | 2007 | Journal of Systems Engineering and Electronics2007，18，3： | 10 |
| 2 | Preparation of phospholipid-based polycarbonate urethanes for potential applications of blood-contacting implants显示文摘Polyurethanes are widely used in interventional devices due to the excellent physicochemical property.However,non-specific adhesion and severe inflammatory response of ordinary polyurethanes may lead to severe complications of intravenous devices.Herein,a novel phospholipid-based polycarbonate urethanes(PCUs)were developed via two-step solution polymerization by direct synthesis based on functional raw materials.Furthermore,PCUs were coated on biomedical metal sheets to construct biomimetic anti-fouling surface.The results of stress–strain curves exhibited excellent tensile properties of PCUs films.Differential scanning calorimetry results indicated that the microphase separation of such PCUs polymers could be well regulated by adjusting the formulation of chain extender,leading to different biological response.In vitro blood compatibility tests including bovine serum albumin adsorption,fibrinogen adsorption and denaturation,platelet adhesion and whole-blood experiment showed superior performance in inhibition non-specific adhesion of PCUs samples.Endothelial cells and smooth muscle cells culture tests further revealed a good anti-cell adhesion ability.Finally,animal experiments including ex vivo blood circulation and subcutaneous inflammation animal experiments indicated a strong ability in anti-thrombosis and histocompatibility.These results high light the strong anti-adhesion property of phospholipid-based PCUs films,which may be applied to the blood-contacting implants such as intravenous catheter or antithrombotic surface in the future. | Peichuang Li Wanhao Cai Xin Li Kebing Wang Lei Zhou Tianxue You Rui Wang Hang Chen Yuancong Zhao Jin Wang Nan Huang | 2020 | Regenerative Biomaterials2020，7，5： | 1 |

| 4 | Cu^(Ⅱ)-loaded polydopaminecoatingswith in situ nitric oxidegenerationfunctionforimproved hemocompatibility显示文摘NO is the earliest discovered gas signal molecule which is produced by normal healthy endothelial cells,and it has many functions,such as maintaining cardiovascular homeostasis,regulating vasodilation,inhibiting intimal hyperplasia and preventing atherosclerosis in the blood system.Insufficient NO release is often observed in the pathological environment,for instance atherosclerosis.It was discovered that NO could be released from the human endogenous NO donor by many compounds,and these methods can be used for the treatment of certain diseases in the blood system.In this work,a series of copper-loaded polydopamine(PDA)coatings were produced through self-polymerization time for 24,48 and 72 h.The chemical composition and structure,coating thickness and hydrophilicity of the different copper-loaded PDA coatings surfaces were characterized by phenol hydroxyl quantitative,X-ray photoelectron spectroscopy,ellipsometry atomic force microscopy and water contact angles.The results indicate that the thickness and the surface phenolic hydroxyl density of the PDA coatings increased with the polymerization time.This copperloaded coating has glutathione peroxidase-like activity,and it has the capability of catalyzing NO releasing from GSNO.The surface of the coating showed desirable hemocompatibility,the adhesion and activation of platelets were inhibited on the copper-loaded coatings.At the same time,the formation of the thrombosis was also suppressed.These copper-loaded PDA coatings could provide a promising platform for the development of blood contact materials. | Lei Zhou Xin Li Kebing Wang Fangyu Shen Lu Zhang Peichuang Li Tengda Shang Jin Wang Nan Huang | 2020 | Regenerative Biomaterials2020，7，2： | 0 |
| 5 | Adhesive and Self-Healing Polyurethanes with Tunable Multifunctionality显示文摘Many polyurethanes(PUs)are blood-contacting materials due to their good mechanical properties,fatigue resistance,cytocompatibility,biosafety,and relatively good hemocompatibility.Further functionalization of the PUs using chemical synthetic methods is especially attractive for expanding their applications.Herein,a series of catechol functionalized PU(CPU-PTMEG)elastomers containing variable molecular weight of polytetramethylene ether glycol(PTMEG)soft segment are reported by stepwise polymerization and further introduction of catechol.Tailoring the molecular weight of PTMEG fragment enables a regulable catechol content,mobility of the chain segment,hydrogen bond and microphase separation of the C-PUPTMEG elastomers,thus offering tunability of mechanical strength(such as breaking strength from 1.3 MPa to 5.7 MPa),adhesion,self-healing eficiency(from 14.9%to 96.7%within 2 hours),anticoagulant,antioxidation,anti-inflammatory properties and cellular growth behavior.As cardiovascular stent coatings,the C-PU-PTMEGs demonstrate enough flexibility to withstand deformation during the balloon dilation procedure.Of special importance is that the C-PU-PTMEG-coated surfaces show the ability to rapidly scavenge free radicals to maintain normal growth of endothelial cells,inhibit smooth muscle cell proliferation,mediate inflammatory response,and reduce thrombus formation.With the universality of surface adhesion and tunable multifunctionality,these novel C-PU-PTMEG elastomers should find potential usage in artificial heart valves and surface engineering of stents. | Lei Zhou Lu Zhang Peichuang Li Manfred F.Maitz Kebing Wang Tengda Shang Sheng Dai Yudie Fu Yuancong Zhao Zhilu Yang Jin Wang Xin Li | 2023 | Research2023，，1： | 0 |
