职业教育作为一种民生工程,因其具有入学门槛低、见效快等特点,能够使贫困生获得自我发展、摆脱贫困的能力,这种造血式帮扶能有效阻断贫困代际相传。目前,职业教育帮扶贫困生脱贫虽取得一定成效,但通过问卷调查和访谈了解到仍有贫困生还存在某种程度的经济贫困、能力贫困和精神贫困等问题。其主要原因在于职业教育精准扶贫机制不健全、职业院校扶贫能力开发不足以及精神扶贫匮乏。为充分发挥职业教育扶贫优势,帮扶贫困生摆脱贫困,需建立健全精准扶贫机制、精准识别贫困对象以精准施策,提升职业院校扶贫开发能力和注重精神扶贫,促进内生动力。

目的研究艾司氯胺酮对大鼠特定骨折模型骨折愈合的影响。方法48只雄性SD大鼠,(200±20)g,用随机数字表法等分为艾司氯胺酮组(KET组)和空白组,每组24只。应用砝码自由下落撞击嵌合器致大鼠右侧胫骨骨折,确定为横形骨折后行内固定,制成右侧胫骨骨折模型。模型制成后第1日起,KET组大鼠腹腔注射艾司氯胺酮(40 mg/kg),每日两次(8:00和20:00),药物注射持续整个实验过程(大鼠处死前一日最后两次注射)。空白组给予相同剂量0.9%NaCl溶液,注射方式、注射时间点以及持续时长同KET组。模型制成后1,2,4周时分别从两组中随机选8只大鼠行右侧颈动脉取血,完成后保留右侧胫骨行脱钙处理。比较两组大鼠血液中脑源性神经营养因子(brain-derived neurotrophic factor,BDNF)、血管内皮生长因子(vascular endothelial growth factor,VEGF)的变化,并分析离体胫骨免疫组化结果中骨形态发生蛋白-2(bone morphogenetic protein-2,BMP-2)染色情况及表达水平。结果KET组骨折部位骨小梁等染色数目多于空白组,KET组BDNF、VEGF、BMP-2水平在各时间点均高于空白组,差异均有统计学意义(P<0.05)。结论艾司氯胺酮可促进大鼠骨折愈合过程,其机制可能与提高BDNF、VEGF水平及增加BMP-2合成有关。

Extant research on Paleozoic mudstone is well developed in the Tarim Basin, while the research on Carboniferous mudstone is relatively weak. Through systematic study of lithology, geochemical characteristics,reservoir characteristics and gas–bearing properties of Carboniferous mudstone in the Tarim Basin, this study aims to provide a geological basis for the Paleozoic shale gas exploration and development, favorable zone optimization, and resource potential evaluation in the Tarim Basin. The results show that the sedimentary environments of organic-rich mudstone in the study area were mainly basin facies and slope facies. Lithology is dominated by black carbonaceous mudstone, followed by calcareous mudstone, siliceous mudstone, and siliceous rocks. Mudstone is mainly developed in the Kalashayi Formation,which is located in the Bachu and Markit slope belt, with the cumulative thickness of 30–200 m. The organic carbon content is commonly more than 0.4%, and the organic matter types are type II and type III. Thermal evolution degree is widely distributed from a low mature to over mature stage, and different tectonic units have a greater difference. The contents of quartz plus feldspar are between 12% and 82.5%, with an average of 45.8%. Thecontent distribution of clay mineral is from 12% to 57%,with an average of 38.2%. Carbonate minerals(mainly siderite) content is below 50%. The brittle mineral content of the mudstone is approximately 65%, with a strong compressibility, and the mudstone has the material basis of forming crack and natural fracture. Microscopic pores in micro–nanometer level are well developed in the mudstone, including micro bedding joint, microcrack,interbedded pores of clay mineral, nanoscale intragranular or edge pores in the massive organic matter, bioclastic micropores, and mineral dissolution pores, etc. According to the standards provided by the Ministry of Land and Resources in China, the Kalashayi Formation in Bamai Area is a favorable area f

作者： Yanxin qiao xinyi Wang Lanlan Yang Xiaojing Wang Jian Chen Zhengbin Wang Huiling Zhou Jiasheng Zou Fuhui Wang School of Materials Science and Engineering Jiangsu University of Science and TechnologyZhenjiang 212003China CAS Key Laboratory of Nuclear Materials and Safety Assessment Institute of Metal ResearchChinese Academy of SciencesShenyang 110016China School of Materials Science and Engineering Northeastern UniversityShenyang 110819China Laboratory for Corrosion and Protection Institute of Metal ResearchChinese Academy of ScienceShenyang 110016China

The effect of aging treatment on the microstructure and corrosion behavior of a Fe-18Cr-15Mn-0.66N high-nitrogen stainless steel(HNSS) in 3.5 wt.% Na Cl solution was investigated using a series of electrochemical tests, scanning electronic microscopy(SEM), X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS). The results showed that the aging treatment led to the precipitation of CrN particles along the grain boundaries and their morphologies changed from dispersive particles to continuous network as the aging time increased up to 60 min. Aging time had minor effects on the corrosion potential and corrosion current density, but resulted in the sharp decrease in the pitting corrosion *** passive film behaved as a n-type semiconductor, and the donor density of the passive film increased with the aging time. Meanwhile, the fraction of stable oxide(CrO) in the passive film decreased with the aging time. It demonstrates that the aging treatment deteriorated the protectiveness of the passive film, hence weakened the corrosion resistance of HNSS.
