地塞米松可以减少由重症急性胰腺炎引起的肾脏微血管内皮糖萼的损伤（英文）

目的:明确地塞米松可以减少重症急性胰腺炎(SAP)引起的肿瘤坏死因子(TNF-α)的释放,减轻TNF-α导致的肾脏血管内皮糖萼的降解,从而改善肾脏微循环和缓解肾损伤。创新点:本研究通过小鼠活体研究的方法,建立小鼠重症急性胰腺炎模型,并用地塞米松进行干预对照,采用透射电镜、激光多谱勒和酶联免疫的方法,检测了各组小鼠肾脏血管内皮糖萼的完整性、肾血流灌注和TNF-α表达情况,阐明了地塞米松对内皮糖萼的保护作用。方法:通过"胰管结扎+腹腔内雨蛙素注射"的方法建立SAP模型,分别留取各组小鼠的血液和组织标本,采用透射电镜观察内皮糖萼的损伤情况,用酶联免疫检测血清TNF-α和糖萼成份多配体聚糖的浓度,并用激光多谱勒检测活体小鼠肾脏的灌注,分析地塞米松对内皮糖萼的保护和改善肾脏灌注的作用。结论:SAP可以引起TNF-α的大量释放,并导致内皮糖萼的降解和肾脏灌注下降,而地塞米松可以减少TNF-α的释放,减轻糖萼的降解,改善肾脏血流灌注。     

Social work students＇ attitude toward poverty in the new economy： A multivariate analysis

This study, conducted at a mid-sized university located in central Canada, had two purposes. The first was to simultaneously assess the influence of undergraduate social work education and other variables such as gender, ethnicity, perceived financial security and political affiliation on students＇ attitude toward poverty. The second was to contribute to the fledgling body of international studies which focus on the area of social work education and perceptions of poverty. The participants in this study were students enrolled in one of three selected undergraduate social work courses or an undergraduate business course. In all of the social work classes, the students were exposed to key ideas and concepts pertaining to poverty and poverty policy, including the cyclical nature of market economies and the challenges and barriers faced by the working poor population. The results indicated that social work education and affiliation with a leftist political ideology predicted a more structural attitude toward poverty.     

2000-2020年中国氮氧化物排放清单及排放趋势

研究目的：建立2000-2020年中国氮氧化物排放清单,了解中国主要行业和省份氮氧化物的排放情况,为评估氮氧化物的环境影响和制定相关减排政策提供依据。创新要点：分析了中国主要省份产业结构对氮氧化物排放量的影响;根据不同情景分析,预测2020年中国氮氧化物的排放量。研究方法：1．基于自底向上法,根据不同类型化石燃料的氮氧化物排放因子,结合化石燃料消耗量,建立中国2000-2010年氮氧化物排放清单;2．基于IPAT方程,并以中国2000--2010年的国内生产总值增长数据和氮氧化物排放量为依据,分三种情景,分析2011-2020年中国能源消耗和氮氧化物排放趋势。重要结论：2010年中国氮氧化物的排放量约是2000年的两倍：自2009年起,中国氮氧化物总排放量超过,二氧化硫总排放量;主要由于产业结构和地区生产总值的不同,中国东部和西部氮氧化物排放量有明显差异;制造业、电力行业和交通运输业是中国氮氧化物的主要排放源,其中交通运输业氮氧化物排放量呈现逐年增长趋势;预计2020年中国氮氧化物排放量为19．7Mt。
