| 1 | Characterization of the Diamond-like Carbon Based Functionally Gradient Film显示文摘Diamond-like carbon coatings have been used as solid lubricating coatings in vacuum technology for their goodphysical and chemical properties. In this paper, the hybrid technique of unbalanced magnetron sputtering and plasmaimmersion ion implantation (PIll) was adopted to fabricate diamond-like carbon-based functionally gradient film,N/TiN/Ti(N,C)/DLC, on the 304 stainless steel substrate. The film was characterized by using Raman spectroscopyand glancing X-ray diffraction (GXRD), and the topography and surface roughness of the film was observed usingAFM. The mechanical properties of the film were evaluated by nano-indentation. The results showed that the surfaceroughness of the film was approximately 0.732 nm. The hardness and elastic modulus, fracture toughness andinterfacial fracture toughness of N/TiN/Ti(N,C)/DLC functionally gradient film were about 19.84 GPa, 190.03 GPa,3.75 MPa.m1/2 and 5.68 MPa@m1/2, respectively. Compared with that of DLC monolayer and C/TiC/DLC multilayer,this DLC gradient film has better qualities as a solid lubricating coating. | FengMA XunCAI GangLI QiulongCHEN HongtaoMA | 2002 | Journal of Materials Science & Technology2002，18，5： | 1 |

| 3 | HOXC4 up-regulates NF-κB signaling and promotes the cell proliferation to drive development of human hematopoiesis, especially CD43+ cells显示文摘The hematopoietic function of HOXC4 has not been extensively investigated.Our research indicated that induction of HOXC4 in co-culture system from D10 significantly promoted productions of most hematopoietic progenitor cells.CD34−CD43+cells could be clearly classified into CD34−CD43^(low) and CD34−CD43^(high) sub-populations at D14.The former cells had greater myelogenic potential,and their production was not significantly influenced by induction of HOXC4.By contrast,the latter cells had greater potential to differentiate into megakaryocytes and erythroid cells,and thus had properties of erythroid–megakaryocyte common progenitors,which abundance was increased by∼2-fold when HOXC4 was induced from D10.For CD34−CD43^(low),CD34+CD43+,and CD34−CD43^(high) sub-populations,CD43 level served as a natural index for the tendency to undergo hematopoiesis.Induction of HOXC4 from D10 caused more CD43+cells sustain in S-phase with up-regulation of NF-κB signaling,which could be counteracted by inhibition of NF-κB signaling.These observations suggested that promotion of hematopoiesis by HOXC4 is closely related to NF-κB signaling and a change in cell-cycle status,which containing potential of clinical applications. | Jiahui Zeng Wencui Sun Jing Chang Danying Yia Lijiao Zhu Yonggang Zhang Xu Pan Ya Zhou Mowen Lai Guohui Bian Qiongxiu Zhou Jiaxin Liu Bo Chen FengMa | 2020 | Blood Science2020，2，4： | 1 |
