| 1 | Mesenchymal stem cells: a new strategy for immunosuppression and tissue repair显示文摘间充质的干细胞(MSC ) 为治疗各种各样的疾病有大潜力,特别那些与织物有关损坏包含有免疫力的反应。各种各样的研究证明了 MSC 在 vitro 并且在 vivo 是强烈抑制免疫力的。我们的最近的研究证明了那未刺激的 MSC 确实不能免疫力的抑制;他们与 TNF- 伪, IL-1 伪或 IL-1 尾与激活的淋巴细胞的上层清液,或与 IFN- 纬的联合在刺激之上变得 potently 抑制免疫力。这观察表明在某些情形下面,煽动性的 cytokines 能实际上变得抑制免疫力。我们证明在调停 MSC 的免疫力的抑制的机制有一个种类变化:由告知 cytokine 的老鼠 MSC 的免疫力的抑制被氮的氧化物调停(没有) 而由告知 cytokine 的人的 MSC 的免疫力的抑制通过 indoleamine 被执行 2, 3-dioxygenase (伊多语) 。在有煽动性的 cytokines 的刺激之上,另外,老鼠和人的 MSC 分泌几白血球 chemokines 显然服务与 MSC 吸引有免疫力的房间进最近,在哪儿不或伊多语被预言很活跃。因此,由煽动性的刺激 cytokine 的 MSC 的免疫力的抑制经由 chemokines 的一致行动发生并且免疫者禁止没有或伊多语由 MSC 生产了。因此,我们的结果在对待有免疫力的回答导致的织物损害关于调停 MSC 的免疫力的抑制并且为 MSC 的更好的申请的机制提供新奇信息。 | Yufang Shi Gangzheng Hu Juanjuan Su Wenzhao Li Qing Chen Peishun Shou Chunliang Xu Xiaodong Chen Yin Huang Zhexin Zhu Xin Huang Xiaoyan Han Ningxia Xie Guangwen Ren | 2010 | Cell Research2010，20，5： | 72 |
| 2 | Fracture characteristics of concrete subjected to impact loading显示文摘This paper takes concrete as a four-phase composite made of the intact matrix and three mutually perpendicular groups of penny-shaped micro-cracks. The intact matrix is assumed to be elastic,homogeneous and isotropic,and the micro-cracks are penny-shaped. Combined with the failure mechanism of concrete subjected to impact loading,a dynamic constitutive model for concrete is developed based on Mori-Tanaka's average stress concept and Eshelby's equivalent inclusion theory. Experimental results show that concrete is rate-dependent. The model predictions are in good agreement with the experimental results. The model may be used to simulate the mechanical behavior of concrete under impact loadings. | LIU HaiFeng1,2,LIU HaiYan3 & SONG WeiDong1 1 State Key Laboratory of Explosion Science and Technology,Beijing Institute of Technology,Beijing 100081,China 2 School of Civil and Hydraulic Engineering,Ningxia University,Yinchuan 750021,China 3 School of Science,Beijing Institute of Technology,Beijing 100081,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，2： | 12 |
| 3 | EXPERIMENTAL INVESTIGATION AND THERMODYNAMIC CALCULATION ON PHASE PRECIPITATION OF INCONEL 740显示文摘A novel nickel-based superalloy INCONEL 740 was under development for application in ultra-supercritical superheater tubers above 750℃. The precipitation behaviors of η phase and γ’ particles of the alloy were investigated through experimental study and phase computation. Experimental results showed that η phase formed a Widmanst?tten pattern structure following long-term exposure at elevated temperatures and that the coarsening of γ’ particle follows a cube rate law:r-3 ∝ t. Thermodynamic calculation results showed that Al and Ti had an important effect on the precipitation behavior of γ’ andη phases. Two suggested novel modified alloys, wherein the Al and Ti contents were modified, were designed and melted for the experimental study. The preliminary results indicated that the modified alloys exhibited higher structural stability following long-term exposure at 750℃ till 5000h. | S.Q.

| 4 | Analysis of Protoscoleces-specific Antigens from Echinococcus Granulosus with Proteomics Combined with Western Blot显示文摘Objective To establish and optimize the proteomic analysis of protoscoleces-specific antigens from Echinococcus granulosus. To provide a foundation for identifying specific antigens in the soluble proteins of E. granulosus protoscoleces for further research. Methods Brood capsules were collected aseptically from fertile E. granulosus cysts from the livers of an infected patient. The fertile E. granulosus cysts were fractured, and protoscoleces were collected by centrifugation. The soluble proteins of protoscoleces were acquired using the 2D Quant kit according to the manufacturer’s instructions. We employed two-dimensional electrophoresis (2-DE) combined with immunoblot assay (Western blot) to analyze the soluble components of E. granulosus protoscoleces antigens. The 2-DE and immunoblot maps obtained were analyzed with PDQuest 8.0 image analysis software. Results About 233 soluble protein spots were identified with Coomassie-stained gels. Most of the proteins had a molecular weight of 16 000 Da to 117 000 Da, and an isoelectric point value of 3.0 to 10.0. 2-DE immunoblot was conducted and 57 specific antigen spots were observed, among which 23 spots were identified. Conclusion 2-DE combined with Western blot is the key to successful proteomic analysis and presents a new possibility for searching the specific E. granulosus protoscoleces antigens. | LI Zong Ji and ZHAO WeiDepartment of Medical Genetics and Cell Biology, Ningxia Medical University, Yinchuan 750004, Ningxia Hui Autonomous Region, China Center of Scientific Technology of Ningxia Medical University, Yinchuan 750004, Ningxia Hui Autonomous Region, China The medical scientific institute of Ningxia, Yinchuan 750004, Ningxia Hui Autonomous Region, China | 2012 | Biomedical and Environmental Sciences2012，25，6： | 7 |
| 5 | Surface characteristics of rapidly solidified nickel-based superalloy pow-ders prepared by PREP显示文摘The surface microstructure and the surface segregation of FGH95 nickel-based superalloy powders prepared through plasma rotating electrode processing (PREP) have been investigated by using SEM and AES. The results indicate that the surface microstructure of powders changes fiom dendrite into cellular structure as the particle size of powders decrease, and the predominant precipitates solidified on the particle surfaces were identified as MC' type carbides enriched with Nb and Ti. It was also indicated that along with the depth of particle surfaces, the segregation layer of S, C and O elements are thick, and that of Ti, Cr elements are thin for large size powders while they are in reverse for median size particles. | CHEN Huanming , HU Benfu , and LI Huiying1) School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China2) School of Physics and Electrical Information Engineering, Ningxia University, Yinchuan 750021, China | 2003 | Rare Metals2003，22，4： | 6 |
| 6 | Archaeological study of ostrich eggshell beads collected from SDG site显示文摘Ostrich eggshell beads and fragments collected from SDG site reflect primordial art and a kind of symbolic behavior of modern humans. Based on stratigraphic data and OSL dating, these ostrich eggshell beads are probably in Early Holocene (< 10 ka BP). Two different prehistoric manufacturing pathways are usually used in the manufacture of ostrich eggshell beads in Upper Paleolithic. According to statistic analysis of the characteristics of ostrich eggshell beads, Pathway 1 is identified from these collections. In pathway 1, blanks are drilled prior to being trimmed to rough discs. They exhibit great potential for the study of the origin of primordial art and the development of ancient cultures and provide important data for studying behavioral options adopted by hominids in SDG area. In addition, they bear important implications for the origin of modern humans in East Asia. | WANG ChunXue1,2,3, ZHANG Yue1,3,4, GAO Xing1,3, ZHANG XiaoLing1,2,3 & WANG HuiMin1,5 1 Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, Beijing 100044, China 2 Graduate School, Chinese Academy of Sciences, Beijing 100039, China 3 Joint Laboratory of Human Evolution and Archaeometry, Chinese Academy of Sciences, Beijing 100044, China 4 State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing 210008, China 5 Ningxia Provincial Institute of Archaeology, Yinchuan 750001, China | 2009 | Chinese Science Bulletin2009，54，21： | 6 |

| 9 | Effects of the CNTF-collagen gel-controlled delivery system on rat neural stem/progenitor cells behavior显示文摘The injury of central nervous system (CNS) usually causes the cavity formation. Although transplantation of neural stem/precursor cells (NSPCs) into the lesioned area of CNS has been shown to be implicated in the functional restoration, the therapeutic result is limited by the poor survival of NSPCs as well as their insufficient proliferation and differentiation abilities. Type-1 collagen is considered as a candidate scaffold or drug delivery system to overcome the aforementioned obstacle. This study observed the effects of the CNTF (ciliary neurotrophic factor)-collagen gel-controlled delivery system and daily addition of soluble-form CNTF on the NSPC survival, migration, proliferation and differentiation. The results showed that, within 12 h of the initial co-culture, CNTF was released in a burst pattern, then the CNTF-collagen gel-controlled delivery system stably released CNTF for up to 12 d. The cell viability test, together with immunohistochemistry, RT-PCR and Western blotting, showed that the CNTF-collagen gel-controlled delivery system supported the NSPCs seeded on the surface of collagen gel survival and facilitated their migration and proliferation. The daily addition of soluble-form CNTF to the medium had similar effects to the CNTF-collagen gel-controlled delivery system, but large quantities of soluble-form CNTF were consumed during the entire process. Taken together, the CNTF-collagen gel-controlled delivery system not only provides a physical scaffold for the transplanted NSPCs to adhere and migrate, but also facilitates the NSPC survival, growth and proliferation, simultaneously reducing the consumption of the expensive growth factors. This system may be used to enhance the microenvironment in the lesioned area of CNS. | YANG ZhaoYang1, QIAO Hui2 & LI XiaoGuang1,3 1School of Biological Science and Medical Engineering, Beihang University, Beijing 100191, China 2Public Heath School, Ningxia Medical University, Yinchuan 750004, China 3Beijing Institute for Neuroscience, Capital Medical University, Beijing 100069, China | 2010 | Science China(Life Sciences)2010，53，4： | 3 |

| 13 | Influence of environmental factors on corrosion damage of aircraft structure显示文摘Corrosion is one of the important structural integrity concerns of aging aircraft, and it is estimated that a significant portion of airframe maintenance budgets is directed towards corrosion-related problems for both military and commercial aircraft. In order to better understand how environmental factors influence the corrosion damage initiation and propagation on aircraft structure and to predict pre-corrosion test pieces of fatigue life and structural integrity of an effective approach, this paper uses the cellular automaton (CA) method to character the effect of electrolyte concentrations, dissolution probabilities, and temperature on the corrosion damage of a metal structure exposed to an aggressive environment, and the procedure for applying the local rules between the cells of the CA to simulate the corrosion damage evolution is formulated. The simulation results show that the different electrolyte concentrations, dissolution probabilities and temperature, the laws of the dissolution current with time are investigated and they obey the time power function. | Keliang Ren,) Shiwu Gao, Pingping Liu, and Yan Dong Department of Physics & Electrical Information, Ningxia University, Ningxia 750021, China | 2011 | Theoretical & Applied Mechanics Letters2011，1，6： | 2 |
