| 1 | IL-37b suppresses T cell priming by modulating dendritic cell maturation and cytokine production via dampening ERK/NF-κB/S6K signalings显示文摘Interleukin 37b (IL-37b ) 在压制有免疫力的回答起一个关键作用,部分由 modulating 树枝状的房间(DC ) 的功能。然而,精确机制大部分仍然是未知的。这里,我们在回答由 DC 导致了的 DC 成熟和 T 房间上调查了 IL-37b 的效果,并且探索了深奥发信号的小径。它被发现那 IL-37b 下面调整在 vitro 的 DC 上的 co-stimulatory 分子 CD80 和 CD86 的表情。同时,支持 inflammatory cytokines 的表情例如 TNF-6, 和 IL-6,被压制,当时 T 房间的表示禁止的 cytokine TGF- 在 IL-37b-treated DC 被增加。另外, T 房间上的 DC 的激活效果被 IL-37b 损害。我们进一步表明细胞外的调整单人赛的 kinase (英皇家空军之阶级最低之兵) ,原子 factor-B (NF-B ) ,和表明小径的 mTOR-S6K 涉及 IL-37b 导致的 DC 的抑制。这被化学禁止者的同样镇压的效果在 DC 在 IL-6 和 TNF- 的表情上对 NF-B,英皇家空军之阶级最低之兵,和 S6K 证实。在结论,这些结果证明 IL-37b 由在英皇家空军之阶级最低之兵, NF-B,和基于 S6K 的禁止的发信号小径包含在 T 房间 priming 压制了 DC 成熟和 immunostimulatory 能力。 | Wantong Wu Weiqiang Wang Yun Wang Wenwen Li Gang Yu Zhonglong Li Chunmin Fang Yue Shen Zhina Sun Ling Han Juan Yu Lijun Fang Song Chen Kui Dong Zhongchao Han Hanzhi Liu Yuechen Luo Xiaoming Feng | 2015 | Acta Biochimica et Biophysica Sinica2015，47，8： | 8 |
| 2 | Laser Remelting of Plasma Sprayed NiCrAlY and NiCrAlY-Al_2O_3 Coatings显示文摘Two types of plasma sprayed coatings (NiCrAlY and NiCrAlY-A12O3) were remelted by a 5 kW cw CO2 laser. With increasing laser power and decreasing traverse speed in the ranges of 200-700 W and 5-30 mm/s respectively, the melted track grew in width and depth. In the optimum range of laser parameters, a homogeneous remelted layer without voids, cavities, unmelted particles and microcracks was formed. On the surface of remelted layers, Al203 and YAIO3 were detected. As a result of isothermal oxidation tests, weight gains of laser remelted coatings were obviously lower than that only plasma sprayed, especially laser remelted NiCrAlY-Al2O3 coatings. The effects of laser remelting and incorporation of A12O3 second phase in N1CrAlY matrix on high temperature oxidation resistance were discussed. | Yingna WU, Gang ZHA NC, Bingchun ZHANG, Zhongchao FENG and Yong LIANG Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China Fangjun LIU Key Laboratory for High Energy Density Beam Processing Technology, Beijing Aeronautical Manu | 2001 | Journal of Materials Science & Technology2001，17，5： | 3 |
| 3 | Further Understanding of the Food Safety Problem显示文摘Frequent occurrence of food quality and safety proves that it is not effective to solve the Problem only from mechanism and supervision mechanism. Instead,it may expand solution ideas from external environment inducing changes of social institutions. Edible agricultural products are raw materials of foods,so their quality and safety are decisive for food quality and safety. Combining with concept of quality and safety of edible agricultural products,from social economy,science,technology and culture,environment cognition,this paper made a further understanding of food quality and safety. It found that the quality and safety of domestic edible agricultural products are not completely resulted from human factor,and not completely quality and safety problem in practical sense. Design of problem solutions should consider such external factors as economic level and consumption concept,dual character of science and technology,cultural quality of the masses,and moral trait of the masses,and enhance matching of building of regulation tools with external environment. | Xingxing MEI Zhongchao FENG Pinghua HE Yawen GAO Yuqin DAI | 2015 | Asian Agricultural Research2015，7，7： | 1 |

| 7 | Surface Modification of Ceramic Materials Using Excimer Laser显示文摘Changes of surface morphology following XeCl excimer laser irradiation were investigated for three engineering ceramic materials (Al2O3, Al2O3-SiC nanocomposite and Si3N4). Al2O3 and Al2O3-SiC nanocomposite samples exhibit a smooth rapid melt layer on the surface, and the formation of the metastable γ-Al2O3 was observed. A silicon-rich layer on the surface was formed after laser irradiation of Si3N4. The toughness K1c of the materials was measured by the indentation fracture method. After laser irradiation, the toughness of Al2O3, Al2O3-SiC nanocomposite and Si3N4 was improved to various degrees:Al2O3-SiC nanocomposite, 60% (max), Al2O3, 40% (max), Si3N4, 12% (max). | Yingna WU, Zhongchao FENG and Jing LIANG (Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110015, China) | 2000 | Journal of Materials Science & Technology2000，16，4： | 0 |
