1Leukemia:研究鉴定出与34种AML白血病亚群相关联的基因突变显示文摘针对成年急性髓细胞白血病(acute myeloid leukemia,AML)患者的一项新的大型研究将80种癌症相关基因突变与5种AML亚型相关联。这5种AML亚型可通过特异性的染色体异常加以确定。在未来,这些发现可能有助指导基因突变测试和治疗决策。A-K Eisfeld K Mrózek J Kohlschmidt D Nicolet S Orwick C J Walker K W Kroll J S Blachly A J Carroll J E Kolitz B L Powell E S Wang R M Stone A de la Chapelle J C Byrd C D Bloomfield 2017现代生物医学进展2017,17,15:7
2健康领域的文化能力显示文摘1背景 尽管人类对其他社会的兴趣纵贯历史的各个阶段,但是检验不同文化概念对人类健康实践的影响从20世纪才开始,当时是伴随着长期的人类学田野调查产生的,这些田野调查揭露了不同文化之间相关卫生实践的多样性、复杂性和连续性。Napier A D Ancarno C Butler B Calabrese j Chater A Chatterjee H Guesnet F Home R Jacyna S Jadhav S Macdonald A Neuendorf U Parkhurst A Reynolds R Scambler G Shamdasani S Smith S Z Stougaard-Nielsen J Thomson L Tyler N Volkmann A M Walker T Watson J Williams AC Willott C Wilson J Woolf K 2016中国卫生政策研究2016,9,2:5

6Macrophage secretory products induce an inflammatory phenotype in hepatocytes显示文摘AIM:To investigate the influence of macrophages on hepatocyte phenotype and function.METHODS:Macrophages were differentiated from THP-1 monocytes via phorbol myristate acetate stimulation and the effects of monocyte or macrophageconditioned medium on HepG2 mRNA and protein expression determined.The in vivo relevance of these findings was confirmed using liver biopsies from 147 patients with hepatitis C virus(HCV)infection.RESULTS:Conditioned media from macrophages,but not monocytes,induced a transient morphological change in hepatocytes associated with upregulation of vimentin(7.8±2.5-fold,P=0.045)and transforming growth factor(TGF)-β1(2.6±0.2-fold,P<0.001)and downregulation of epithelial cadherin(1.7±0.02-fold,P=0.017)mRNA expression.Microarray analysis revealed significant upregulation of lipocalin-2(17-fold,P <0.001)and pathways associated with inflammation,and substantial downregulation of pathways related to hepatocyte function.In patients with chronic HCV,realtime polymerase chain reaction and immunohistochemistry confirmed an increase in lipocalin-2 mRNA(F0 1.0 ±0.3,F1 2.2±0.2,F2 3.0±9.3,F3/4 4.0±0.8,P= 0.003)and protein expression(F1 1.0±0.5,F2 1.3± 0.4,F3/4 3.6±0.4,P=0.014)with increasing liver injury.High performance liquid chromatography-tandem mass spectrometry analysis identified elevated levels of matrix metalloproteinase(MMP)-9 in macrophageconditioned medium,and a chemical inhibitor of MMP-9 attenuated the change in morphology and mRNA expression of TGF-β1(2.9±0.2 vs 1.04±0.1,P<0.001) in macrophage-conditioned media treated HepG2 cells.In patients with chronic HCV infection,hepatic mRNA expression of CD163(F0 1.0±0.2,F1/2 2.8±0.3,F3/4 5.3±1.0,P=0.001)and MMP-9(F0 1.0±0.4,F1/2 2.8±0.3,F3/4 4.1±0.8,P=0.011)was significantly associated with increasing stage of fibrosis.CONCLUSION:Secreted macrophage products alter the phenotype and function of hepatocytes,with increased expression of inflammatory mediators,suggesting that hepatocytes actively participate in liver injury.Michelle Melino Victoria L Gadd Gene V Walker Richard Skoien Helen D Barrie Dinesh Jothimani Leigh Horsfall Alun Jones Matthew J Sweet Gethin P Thomas Andrew D Clouston Julie R Jonsson Elizabeth E Powell 2012World Journal of Gastroenterology2012,18,15:3
7Psychosocial mechanisms for the transmission of somatic symptoms from parents to children显示文摘AIM: To examine familial aggregation of irritable bowel syndrome(IBS) via parental reinforcement/modeling of symptoms, coping, psychological distress, and exposure to stress.METHODS:Mothers of children between the ages of8 and 15 years with and without IBS were identified through the Group Health Cooperative of Puget Sound.Mothers completed questionnaires,including the Child Behavior Checklist(child psychological distress),the Family Inventory of Life Events(family exposure to stress),SCL-90R(mother psychological distress),and the Pain Response Inventory(beliefs about pain).Children were interviewed separately from their parents and completed the Pain Beliefs Questionnaire(beliefs about pain),Pain Response Inventory(coping)and Child Symptom Checklist[gastrointestinal(GI)symptoms].In addition,health care utilization data was obtained from the automated database of Group Health Cooperative.Mothers with IBS(n=207)and their 296 children were compared to 240 control mothers and their 335 children,while controlling for age and education.RESULTS:Hypothesis 1:reinforcement of expression of GI problems is only related to GI symptoms,but not others(cold symptoms)in children.There was no significant correlation between parental reinforcement of symptoms and child expression of GI or other symptoms.Hypothesis 2:modeling of GI symptomsis related to GI but not non-GI symptom reporting in children.Children of parents with IBS reported more non-GI(8.97 vs 6.70,P<0.01)as well as more GI(3.24 vs 2.27,P<0.01)symptoms.Total health care visits made by the mother correlated with visits made by the child(rho=0.35,P<0.001 for cases,rho=0.26,P<0.001 for controls).Hypothesis 3:children learn to share the methods of coping with illness that their mothers exhibit.Methods used by children to cope with stomachaches differed from methods used by their mothers.Only 2/16 scales showed weak but significant correlations(stoicism rho=0.13,P<0.05;acceptance rho=0.13,P<0.05).Hypothesis 4:mothers and children share psychological traits such as anxiety,depression,and somatization.Child psychological distress correlated with mother’s psychological distress(rho=0.41,P<0.001 for cases,rho=0.38,P<0.001 for controls).Hypothesis 5:stress that affects the whole family might explain the similarities between mothers and their children.Family exposure to stress was not a significant predictor of children’s symptom reports.Hypothesis 6:the intergenerational transmission of GI illness behavior may be due to multiple mechanisms.Regression analysis identified multiple independent predictors of the child’s GI complaints,which were similar to the predictors of the child’s non-GI symptoms(mother’s IBS status,child psychological symptoms,child catastrophizing,and child age).CONCLUSION:Multiple factors influence the reporting of children’s gastrointestinal and non-gastrointestinal symptoms.The clustering of illness within families is best understood using a model that incorporates all these factors.Miranda AL van Tilburg Rona L Levy Lynn S Walker Michael Von Korff Lauren D Feld Michelle Garner Andrew D Feld William E Whitehead 2015World Journal of Gastroenterology2015,21,18:2

11文化、不平等性与卫生服务提供显示文摘1动态不平等性对基层医疗卫生人力的影响 政治、社会、文化、专业群体皆建立在一致且常规的人类行为之上。当遭受巨大变革和内外压力时,这些群体会变得十分脆弱。尤其在动荡时期,这些群体往往更关注社会和文化的差异性,而非二者的一致性。尽管社会中的个体思维和行为会呈现较大的差异,但对健康的感知具有统一性,并在更广范围人群内尤为突出,这主要归因于文化价值观的作用。广义的文化心态会随着时间和地理位置的不同而不同,就像健康的社会决定因素也会因文化类型的不同而产生差异。Napier A D Ancarno C Butler B Calabrese J Chater A Chatterjee H Guesnet F Horne R Jacyna S Jadhav S Macdonald A Neuendorf U Parkhurst A Reynolds R Scambler G Shamdasani S Smith S Z Stougaard-Nielsen J Thomson L Tyler N Volkmann A M Walker T Watson J Williams A C Willott C Wilson J Woolf K 2016中国卫生政策研究2016,9,3:2
