1社会、经济与环境因素对老年健康和死亡的影响——基于中国22省份的抽样调查显示文摘基于全国22省市886个县15 973位老人2002—2005年跟踪调查数据,本文应用多水平多元logit模型,对社会、经济和环境因素对老年健康和死亡的影响进行了分析。结果表明,控制了个人层面相关变量后,空气污染显著增加了老人ADL(日常生活自理能力)残障、认知功能差与累计健康亏损指数上升的可能性。降雨量的增加则显著降低了老人ADL残障和认知功能差的风险。极低的气温显著增加了老人ADL残障的风险与死亡风险,而极高的气温显著增加了老人认知功能差和累计健康亏损指数上升的可能性。居住在山区的老人ADL残障风险较低,累计健康亏损指数亦较低。此外,人均GDP、15~64岁人口的劳动参与率以及文盲率对中国老年人的生理健康、心理健康、整体健康水平以及死亡风险有显著的、作用方向不同的影响。最后,得出如下结论:保护自然环境、改善社会经济状况的干预措施将有利于改善老人健康、降低老人死亡风险。曾毅 顾大男 Jama Purser Helen Hoenig Nicholas Christakis 2014中国卫生政策研究2014,7,6:46
2放牧绵羊瘤胃液挥发性脂肪酸的变化规律及其受蠕虫感染的影响显示文摘选用敖汉细毛羊的育成母羊和成年母羊进行了3年试验。第1年试验在同一饲养水平下设对照组、常规驱虫组和缓释胶囊驱虫组;第2年和第3年又在常规饲养和改进饲养2种饲养方案下进行驱虫试验。所有试验羊在以披碱草、羊草和冰草为主的同类草场上放牧,每年进行3次驱虫处理。试验表明:放牧绵羊瘤胃液中挥发性脂肪酸(VFA)浓度随季节呈动态变化。其挥发性脂肪酸总量(TVFA)在青草期内较高;在枯草期内较低。放牧绵羊瘤胃发酵水平较低,特别在冬春季节内瘤胃发酵处于最低水平,发酵质量不高。另外,绵羊瘤胃液pH值随季节变动幅度较小。但发现在枯草期内的瘤胃液pH值高于青草期,特别在冬春季节内较高。蠕虫感染严重的时期内,蠕虫会影响绵羊瘤胃发酵水平,使瘤胃液VFA浓度降低;但常规驱虫法与缓释胶囊驱虫法间差异不显著。改进饲养与常规饲养方案对绵羊瘤胃液挥发性脂肪酸总量无显著影响。王洪荣 冯宗慈 卢德勋 王晓冬 任家琨 李志明 李恒荣 王庆基 张富 D B Purser D W Peter J Lindsay 2010畜牧与饲料科学2010,31,6:3
3Variations in Wool Growth with Nutrient Supply in Northern China显示文摘Field studies on essessment of nutritional status of the grazing sheep were carried out in each of the three major grassland regions, the eastern Inner Mongolia and beyond grassland, the Inner Mongolia - Ningxia - Gansu grassland and the Xinjiang grassland, in northern China. The results obtained showed that the wool production of fine wool sheep in these regions varied between regions and seasons, with similar seasonal patterns in all regions and that reducing the seasonal variations in nutrient supply would enhance wool production substantially. Nutritional limitations to wool growth of the grazing sheep in these regions were suggested, those were: the shortage of protein supply in winter and early spring; the poor quality of much of the pasture and the hay used as supplements, the low energy intake during winter which probably necessitated the use of body stores to maintain body temperature.D X Lu,Iner(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)Z C Feng,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)H R Wang,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)R Z Yang,(Xinjiang Institute of Animal Science.Xinjiang Academy of Animal Science.Yiu Hou Road.Urumqi.Xinjiang Uygur Autonomous Region PRC)C T Ma,(Chinese Academy of Agricultural Sciences.Lanzhou.Gansu.PRC)D B Purser,(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)J R Lindsay(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)D W Peter(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014) 1997畜牧与饲料科学1997,22,S1:3
4SD大鼠长期高盐饮食可导致其高血压并改变肾细胞因子基因表达谱(英文)显示文摘Objective:The present study examines whether a long-term high salt diet causes hypertension and renal injury in normal subjects [Sprague-Dawley(SD) rats] and alters renal cytokine-related gene expression profiles.Methods: Four 10 week old male SD rats received a high salt diet(HS,8%) and the other 4 SD rats received a normal salt diet(NS,0.5 %) for 8 weeks.Mean arterial pressure(MAP) and renal damages such as albuminuria and histological renal injury were determined.The relative mRNA levels of 514 cytokine-related genes(normalized by β-actin) in rat kidneys following NS or HS were determined quantitatively through analysis of 4 sets of gene expression profiles using the mouse cDNA membrane microarrays.Results: We demonstrated that 8 weeks of HS diet increased MAP [(140.0±5.3) vs(112.0±2.2) mmHg;1 mmHg=0.133 kPa,P<0.01],albuminuria [(41.4±3.2) vs(20.1±4.5) mg/d;P<0.01],and caused histological renal injury in SD rats,compared to NS group.Of the 514 genes in the array,there were 27(5.25%) genes with significantly different expression in the kidney of SD rats with HS compared to those of SD rats with NS.Functional clustering analysis indicated the following functional pathways related to high salt diet-induced hypertension:(1) pro-inflammatory response(↑IL-17,CCL28;↓NFκbib);(2) endothelial dysfunction(↓VEGF-A,VEGF-B,endoglin);(3) pro-matrix formation(↑osteopontin,IGFBP-5;↓IFN-γ);and(4) attenuated cell survival and differentiation(↓CNTF,IGF-Ⅱ R,ephrin-B1).Northern blot confirmed that 8 weeks of HS diet significantly decreased renal expression of VEGF mRNA,compared to NS group(P<0.01).ELISA showed that HS diet significantly decreased renal protein levels of VEGF and CCL28.Conclusion: These findings support the hypothesis that hypertension can be induced in normal rats by a long-term high salt diet,which is associated with increased renal injury and marked changes in renal cytokine gene expression profiles that are closely related to the pro-inflammatory response,pro-matrix formation,endothelial dysfunction,and attenuated cell survival and differentiation.Emily YOUNG Kevan B.TUCKER Megan SHPARAGO Amelia Purser BAILEY 2009北京大学学报(医学版)2009,41,5:2
