A Cross-Sectional,Correlational Study Comparing Individual Characteristics of Younger and Older Nursing Home Residents using Western Canadian Resident Assessment Instrument–Minimum Data Set (RAI-MDS) 2.0

ObjectiveTo compare characteristics of nursing home (NH) residents by age categories in Western Canada.DesignA cross-sectional, correlational analysis of secondary data.Setting and Participants89,231 residents living in Western Canada NHs in the provinces of Alberta, Manitoba, and British Columbia in 2016 and 2017.MethodsResident characteristics (age, sex, marital status, body mass index, medical diagnoses, cognitive function, physical function, depressive symptoms) came from the Resident Assessment Instrument–Minimum Data Set 2.0 and were analyzed using chi-square, analysis of variance, and post hoc pairwise tests. Human developmental stage age categories were used to create 5 age groups: 18-34, 35-50, 51-64, 65-80, and 81 years and older.ResultsThe demographics, medical diagnoses, cognitive function, and physical function characteristics of NH residents among 5 age groups differed considerably (all P < .001). Residents aged 18-34 years were predominately male, never married, with a higher incidence of paralysis and traumatic brain injury. Residents aged 35-50 years had a higher incidence of stroke and multiple sclerosis, and residents aged 51-64 years mainly were morbidly obese and more prone to depression. Residents aged 65-80 years were predominately married and more prone to diabetes, and residents aged 81 years and older were predominately widowed, with a higher incidence of dementia compared with others.Conclusions and ImplicationsFindings describe the uniqueness of younger NH age groups and indicate that the youngest NH residents often have the severe disability and a modest support system (as defined by partnered status) compared to older residents in NHs. Future studies must analyze longitudinal data that track the growth of, and changes in, residents’ health and functional status.     

中西医结合治疗眼底病的实验和临床研究

眼底病是一种复杂的致盲率很高的眼部疾病 ,包括视网膜脱离、视网膜玻璃体出血和增殖性玻璃体视网膜病变 (PVR)等疾病。本文采用中西医结合的治疗方法对动物模型和 1998～ 2 0 0 0年此类眼病患者进行研究 ,疗效显著 ,使眼底病的治愈率有了很大幅度的提高。中医药对眼底病的治疗常用活血化瘀复方治疗 ,对于从动物实验及临床两方面同时进行中西医结合的系统治疗研究 ,尚未见有报道。     

缺氧预适应小鼠脑组织中缺氧诱导因子-1的表达

为探讨缺氧诱导因子 1 (HIF 1 )在缺氧预适应小鼠脑组织中的表达 ,用Western印迹法检测慢性缺氧 (H)和不缺氧 (C)HeLa细胞、急性重复性缺氧 0次 (H0 )、1次 (H1)、4次 (H4 )小鼠脑组织中的HIF 1α。结果 :慢性缺氧HeLa细胞中可检测到较多的HIF 1α,H0 组脑组织中检测不到HIF 1α ,H1组检测到微量HIF 1α,H4 组检测到较多HIF 1α。结果显示 :脑组织中HIF 1α的含量随缺氧预适应的产生而逐步增加 ,提示HIF 1可能参与缺氧预适应的形成。

L-NAME对肝硬化大鼠胃肠道中一氧化氮合酶亚型表达的影响

目的 研究一氧化氮合酶亚型（NOS1,NOS2,NOS3）在肝硬化大鼠胃肠道中的表达,并探讨NOS抑制剂左旋硝基精氨酸甲基酯（L-NAME）对其表达的影响。方法 制作大鼠四氯化碳中毒肝硬化模型,肝硬化模型大鼠随枘发为NO合酶（NOS）抑制剂治疗组和未治疗组,模型治疗组用L-NAME0.5mg.kg^-1.d^-1,胃内注入,每日1次,治疗10d,免疫组织化学染色显示胃肠道组织中型NOS的染色强度和分布,Western blot法检测胃肠道组织中各型NOS的表达。结果 模型组大鼠胃、小肠、结肠组织 的NOS染色强度显著弱于正常对照组和L-NAME治疗组大鼠。Western blot显示在肝硬化模型大鼠胃、小肠、结肠组织中的各型NOS表达均明显降低,L-NAME治疗后又恢复至接近正常。结论 肝硬化大鼠胃肠道组织中各型NOS的表达明显减少,L-NAME对其表达有调节作用。

间接免疫荧光法及蛋白质印迹法对肺癌患者体内自身抗体的分析

目的：了解肺癌患者血清自身抗体阳性率、细胞内定位及荧光图形特点,探索自身抗体作为肿瘤樗物的可能性。方法：应用间接免疫荧光法（ｉｎｄｉｒｅｃｔ ｉｍｍｕｎｏｆｌｕｏｒｅｓｓｅｅｎｅｅ,ＩＩＦ）检测７７份肺癌以及１４０份不同年龄段正常人血清中自身抗体。提取人喉癌上皮细胞（Ｈｅｐ－２）蛋白抗原,采用蛋白质印迹法对８１份肺癌患者及５２份正常人血清进行分析。结果：肺癌组和对照组的自身抗体阳性率有显著差别,两     

碘对自身免疫性甲状腺疾病外周血单个核细胞HLA-DR表达的影响
