1Assessment of the uncertainties in temperature change in China during the last century显示文摘We have used the China Homogenized Historic Temperature dataset and some long-term station series of the neighbor countries from CRUTEM3,a 5°×5° gridded dataset of monthly mean temperature since 1900,to provide a 107-year record of surface temperature trends and variability.We derived a comprehensive set of uncertainty estimates to accompany the data:measurement and sampling errors,uncertainties in temperature bias estimates,and uncertainties arising from limited observational coverage on large-scale averages have all been estimated.We reanalysed the temperature changes during the period of record.The best estimates of trends for 1900-2006 with uncertainties at 95% confidence range are about 0.09±0.017°C/decade for the year as a whole,and 0.14±0.021°C/decade,0.11±0.021°C/decade,0.04±0.017°C/decade,and 0.07±0.017°C/decade for winter,spring,summer and autumn respectively.For 1954-2006,the trends for annual,winter,spring,summer and autumn are:0.26±0.032°C/decade,0.35±0.046°C/decade,0.25±0.051°C/decade,0.16±0.037°C/decade and 0.22±0.055°C/decade.Winter saw the most significant warming trend in both 1900-2006 and 1954-2006,while during the most recent period(the satellite era,1979-2006),all the seasons show similar warming trends:0.45±0.13°C/decade,0.51±0.11°C/decade,0.52±0.16°C/decade,0.37±0.10°C/decade and 0.50±0.16°C/decade for annual,winter,spring,summer and autumn.Trends arising from urbanization have been evaluated as less than 5% of the total warming trend for 1951-2001,so this bias was not removed.LI QingXiang DONG WenJie LI Wei GAO XiaoRong JONES P KENNEDY J PARKER D 2010Chinese Science Bulletin2010,55,19:26
2我国农村居民的红细胞脂肪酸、血浆脂质与心血管疾病显示文摘对我国49个县的心血管疾病(CVD,包括冠心病、高血压心脏病和脑卒中)死亡率和4900例35~64岁成年男女的膳食进行了调查,并测定了血浆脂质[总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)和甘油三酸酯(TG)]的含量,结果指出:1.和西方国家人群比较,我国农民血浆TC、TG、HDL-C和依此计算而得的LDL-C水平较低,而HDL-C/TC比值较高,CVD死亡率也较西方国家的为低。2.在TC、LDL-C与CVD死亡率之间无相关,但在红细胞油酸水平与CVD死亡率间有显著负相关。3.红细胞油酸水平与血浆TC含量间无相关,而与红细胞花生四烯酸水平呈显著负相关。指出油酸对CVD死亡率的影响有可能是通过另一条途径,即减低血小板的聚集作用。4.我国的CVD死亡率呈现明显的地区性分布,即南方低于北方。其分布与红细胞油酸含量,及大米摄取量的地区性分布呈明显的负关系。5.为解释CVD死亡率与红细胞油酸的负关系,本文提出了油酸可能置换了血小板膜磷脂中多不饱和脂肪酸的设想,但对大米保护CVD的作用则尚需有更多的调查和研究数据才能确证之。范文洵 Parker R Parpia B 屈荫生 Cassano P Crawford M Leyton J 田巧珍 黎均耀 陈君石 Campbell C 1992营养学报1992,14,1:15
3Using quality improvement methods to increase use of pain prevention strategies for childhood vaccination显示文摘AIM To increase evidence-based pain prevention strategy use during routine vaccinations in a pediatric primary care clinic using quality improvement methodology.METHODS Specific intervention strategies(i.e.,comfort positioning,nonnutritive sucking and sucrose analgesia,distraction) were identified,selected and introduced in three waves,using a Plan-Do-Study-Act framework.System-wide change was measured from baseline to post-intervention by:(1) percent of vaccination visits during which an evidence-based pain prevention strategy was reported as being used; and(2) caregiver satisfaction ratings following the visit.Additionally,self-reported staff and caregiver attitudes and beliefs about pain prevention were measured at baseline and 1-year post-intervention to assess for possible long-term cultural shifts.RESULTS Significant improvements were noted post-intervention.Use of at least one pain prevention strategy was documented at 99% of patient visits and 94% of caregivers were satisfied or very satisfied with the pain prevention care received.Parents/caregivers reported greater satisfaction with the specific pain prevention strategy used [t(143) = 2.50,P ≤ 0.05],as well as greater agreement that the pain prevention strategies used helped their children's pain [t(180) = 2.17,P ≤ 0.05] and that they would be willing to use the same strategy again in the future [t(179) = 3.26,P ≤ 0.001] as compared to baseline.Staff and caregivers also demonstrated a shift in attitudes from baseline to 1-year post-intervention.Specifically,staff reported greater agreement that the pain felt from vaccinations can result in harmful effects [2.47 vs 3.10; t(70) =-2.11,P ≤ 0.05],less agreement that pain from vaccinations is 'just part of the process' [3.94 vs 3.23; t(70) = 2.61,P ≤ 0.05],and less agreement that parents expect their children to experience pain during vaccinations [4.81 vs 4.38; t(69) = 2.24,P ≤ 0.05].Parents/caregivers reported more favorable attitudes about pain prevention strategies for vaccinations across a variety of areas,including safety,cost,time,and effectiveness,as well as less concern about the pain their children experience with vaccination [4.08 vs 3.26; t(557) = 6.38,P ≤ 0.001],less need for additional pain prevention strategies [3.33 vs 2.81; t(476) = 4.51,P ≤ 0.001],and greater agreement that their doctors' office currently offers pain prevention for vaccinations [3.40 vs 3.75; t(433) =-2.39,P ≤ 0.05].CONCLUSION Quality improvement methodology can be used to help close the gap in implementing pain prevention strategies during routine vaccination procedures for children.Jennifer Verrill Schurman Amanda D Deacy Rebecca J Johnson Jolynn Parker Kristi Williams Dustin Wallace Mark Connelly Lynn Anson Kevin Mroczka 2017World Journal of Clinical Pediatrics2017,6,1:3
4Metabolite profile comparisons between ascending and descending colon tissue in healthy adults显示文摘BACKGROUND Obesity is a risk factor for colorectal cancer,yet metabolic distinctions between healthy right and left colon tissue,before cancer is diagnosed,remains largely unknown.This study compared right-ascending and left-descending colon tissue metabolomes to identify differences from the stool metabolome in normal weight,overweight,and obese adults.AIM To examine right and left colon tissue metabolites according to body mass index that may serve as mechanistic targets for interventions and biomarkers for colon cancer risk.METHODS Global,non-targeted metabolomics was applied to assess right-ascending and left-descending colon tissue collected from healthy adults undergoing screening colonoscopies to test the hypothesis that BMI differentially impacts colon tissue metabolite profiles.The colon tissue and stool metabolome of healthy adults(n=24)was analyzed for metabolite signatures and metabolic pathway networks implicated in progression of colorectal cancer.RESULTS Ascending and descending colon contained 504 host,food,and microbiotaderived metabolites from normal weight,overweight and obese adults grouped according to body mass index.Amino acids,lipids,and nucleotides were among the chemical types that further differentiated from the stool metabolite profiles.Normal weight adults had 46 significantly different metabolites between ascending and descending colon tissue locations,whereas there were 37 metabolite differences in overweight and 28 metabolite differences for obese adults(P<0.05).Obese adults had trimethylamine N-oxide,endocannabinoids and monoacylglycerols with different relative abundances identified between ascending and descending colon.Primary and secondary bile acids,vitamins,and fatty acids also showed marked relative abundance differences in colon tissue from overweight/obese adults.CONCLUSION There were metabolite profile differences between right-ascending and leftdescending colon tissue in healthy adults.Colon lipids and other metabolites in obese and overweight adults were distinguished from normal weight participants and associated with gut inflammation,nutrient absorption,and products of microbiota metabolism.Bridget A Baxter Kristopher D Parker Michael J Nosler Sangeeta Rao Rebecca Craig Catherine Seiler Elizabeth P Ryan 2020World Journal of Gastroenterology2020,26,3:2
