Secondary Prevention of Cardiovascular Disease in Older Adults

Atherosclerotic cardiovascular disease is extremely common in older adults and the potential benefits of secondary prevention are perhaps greater in this population than in younger patients. While there is good evidence that secondary prevention efforts are justified in patients up to 80 years of age, limited data are available on secondary prevention in octogenarians and there is no evidence to guide treatment in patients ≥ 90 years of age. Further, the value of secondary prevention may be confounded by prevalent comorbidities, polypharmacy, and limited life expectancy. It is therefore essential that all management decisions be made in relation to individual preferences and goals of care, with understanding by patients that benefits as well as risks may increase with age. Furthermore, research is needed to refine markers to better delineate which older adults are most likely to benefit from preventive therapies.     

葡萄糖转运蛋白1和波形蛋白在肺癌胸水中的应用价值

目的:采用免疫细胞化学技术测定葡萄糖转运蛋白1(GLUT1)及波形蛋白(VM)在癌细胞中的定位表达,探讨GLUT1和VM在肺癌胸水中的应用价值。方法:以肺癌患者为研究对象,以肺癌性胸水为检测基础,收集胸水沉淀细胞,制成石蜡切块,采用免疫组化技术-链霉菌抗生物素-过氧化物霉法检测30例肺癌胸水和20例良性胸水中GLUT1和VM蛋白表达,统计单个及联合应用价值。结果:30例肺癌胸水中,GLUT1表达阳性的有25例(86.7%),良性胸水中间皮细胞VM表达阳性的有18例(90.0%),两种不同性质的胸水GLUT1和VM的阳性率表达均有差异(P<0.05),GLUT1和VM在肺癌胸水中表达呈负相关(P<0.05),两者联合诊断灵敏度为90%。结论:应用免疫组化方法检测肺癌胸水中GLUT1和VM蛋白表达,可提高肺癌早期诊断的灵敏度。     

iRoot SP��AH Plus�������ڸ�������Ч����Meta����

??Objective    To systematically evaluate the effect of iRoot SP and AH Plus paste in the treatment of root canal. Methods    Online databases including PubMed??EMBASE??the Cochrane Library??Web of Knowledge??and Chinese databases ??Wanfang database??VIP and CNKI?? were searched systematically up to February 2017. Randomized controlled trials and high-quality comparative studies were considered eligible for inclusion. Two qualified reviewers reviewed the original articles??evaluating qualities of articles??and extracting data independently. After heterogeneity test??Meta-analysis was performed. Results    In total??seven original clinical controlled trials were included??containing 493 teeth. iRoot SP paste could improve the immediate root canal quality ??OR=0.30??95%CI????0.10 ~ 0.85?????reduce the rate of postoperative pain ??OR=0.23??95%CI????0.06 ~ 0.89?????and decrease the apical leakage ??WMD=-0.13??95%CI????-0.22 ~ -0.05????. Conclusion    iRoot SP paste in root canal therapy can significantly alleviate pain??and the long-term curative effect is good??has better biological compatibility??which is an ideal root canal filling material. Because of the small number of the literatures included??which are all in China??it is necessary to include large sample??multicenter??randomized??double-blind??placebo-controlled trails to further confirm the clinical effect.
