| 1 | LARGELY IMPROVED BLOOD COMPATIBILITY OF POLYURETHANE BY BLENDING WITH FLUORINATED PHOSPHATIDYLCHOLINE POLYURETHANE显示文摘The improvement of biocompatibility of polyurethanes was investigated.The results demonstrate that the blood compatibility of polyurethanes can be further improved by just simply mixing with the fluorinated phosphatidylcholine poly(carbonate urethane)s(FPCPCUs).The solution blending was done by mixing poly(ether urethane)(PEU)with FPCPCU in different compositions.An increased blood compatibility of the blend films was observed with the increase of FPCPCU content,and when FPCPCU content reached to 40 wt%(... | 傅强 | 2008 | Chinese Journal of Polymer Science2008，26，2： | 3 |
| 2 | An Emergency Blood Allocation Approach Considering Blood Group Compatibility in Disaster Relief Operations显示文摘Large-scale sudden-onset disasters may cause massive injuries and thus place great pressure on the emergency blood supplies of local blood banks. When blood is in short supply, blood products gathered urgently to a local blood center should be appropriately allocated to blood banks in the affected area. Moreover, ABO/Rh(D) compatibilities among blood groups must be considered during emergency situations. To minimize the total unmet demand of blood products considering the optimal ABO/Rh(D)-compatible blood substitution scheme, a mixed integer programming model is developed and solved efficiently by using a greedy heuristic algorithm. Finally, a numerical example derived from the emergency blood supply scenario of the Wenchuan Earthquake is presented to verify the proposed model and algorithm. The results show that considering ABO/Rh(D)-compatible blood substitution can remarkably increase the efficiency of emergency blood allocation while lowering blood shortage, and the preference order of possible ABO/Rh(D)-compatible substitutions has an influence on the allocation solution. | Zu-Jun Ma Ke-Ming Wang Ying Dai | 2019 | International Journal of Disaster Risk Science2019，10，1： | 2 |
| 3 | Synthesis and blood compatibility of rutile-type titanium oxide coated LTI-carbon显示文摘Titanium oxide films were synthesized by ion beam enhanced deposition, where the films were prepared by depositing titanium atoms and simultaneously bombarding with Xe + ions at an energy of 40 keV in an O 2 environment. The titanium oxide films exhibit rutile type structure with (100) orientation and the O/Ti ratio is about 2∶1. Ti 2+ , Ti 3+ and Ti 4+ coexist in the films. In vitro and in vivo investigations were used to investigate the blood compatibility of titanium oxide films. The results show that the blood compatibility of rutile type titanium oxide films is better than that of low temperature isotropic pyrolytic carbon (LTI carbon), which is widely used to fabricate artificial heart valve. It is thought that rutile type titanium oxide coated LTI carbon most probably becomes new biomaterial to fabricate artificial heart valves. | 张峰 陈宇 郑志宏 黄楠 柳襄怀 陈安清 蒋振斌 | 1998 | Science China(Life Sciences)1998，41，4： | 1 |
| 4 | Blood compatible heteratom-doped carbon dots for bio-imaging of human umbilical vein endothelial cells显示文摘Carbon dots have unique advantages in biological applications owing to their excellent optical prope rties.However,the biosafety evaluation of carbon dots has limitations owing to cytotoxicity in vitro,and the re is little pre-safety evaluation before in vivo and clinical applications.Whether the carbon dots are or not suitable for applications in vivo,evaluation analysis can be made based on hemolysis and changes in erythrocyte morphology.In this work,a green fluorescent N,S-doped carbon dots(N,S-CDs)were obtained by hydrothermal method,tobias acid,and m-phenylenediamine as precursors.N,S-CDs not only possessed excellent dispersibility,uniform particle size,high quantum yield(37.2%)and stable photoluminescence property but also retain their photostability and stro ng fluorescence intensity in the acid/alkaline solutions,different ionic strengths(NaCl)and under 365 nm UV illumination.Moreove r,the N,S-CDs displayed low cytotoxicity and high cellular uptake efficiency in human umbilical vein endothelial cells(HUVEC)and excellent blood compatibility to the erythrocyte.It is foreseeable that N,S-CDs could be further studied as a promising biological imaging agent in vivo. | Jian Zhong Xinmian Chen Miaoran Zhang Chaoxin Xiao Lulu Cai Waleed Ali Khan Kaixuan Yu Jiayi Cui Lin He | 2020 | Chinese Chemical Letters2020，31，3： | 0 |
| 5 | Blood Compatibility of Nano-Hydroxyapatite Dispersed Using Various Agents显示文摘Nano-hydroxyapatite (nHAP),dispersed with three kinds of dispersants (heparin sodium,polyacrylic sodium and wa-ter),reacted with red blood cell,Bel-7402 tumor cell,to compare their dispersing efficiency against nHAP from one another. The blood compatibility of nHAP is also determined by blood solubil-ity experiment so that the capability of different dispersant dis-persing against nHAP of different concentration and the relation between nHAP and blood compatibility have been determined. The inhibiting function of Bel-7402 against tumor cells is deter-mined with the MTT staining method. The study result shows that heparin sodium has the best dispersing efficiency for nHAP with-out the phenomenon of hemolysis. | YANG Lijian1, JIN Huafang2, YUAN Lin2 1.

| 6 | The grafting PET and PVA fibers coated with soybean lecithin and their blood-compatibility properties显示文摘the composites of grafting polystyrene polyvinyl acetate (PVA) or polyethylene terephthalate (PET) coated with soybean lecithin, are obtained. Results of grafting experiments show that the grafting ratio on the surface of the fibers is low when the grafting polymer chain is not cross linked. Under scanning electron microscope (SEM), it is discovered that there is no different morphology between the raw fibers and their being coated with soybean lecithin. The composites exhibit a good stability of soybean lecithin layer, and better anti coagulant property than the sulfonated grafting fibers or raw fibers. | TANG Shun qing, ZHOU Chang ren Biomedical Engineering Institute, Jinan University, Guangzhou,510632,China | 2002 | Chinese Journal of Biomedical Engineering(English Edition)2002，11，2： | 0 |
