目的 系统评价Omega-3脂肪酸用于肿瘤恶液质患者口服营养补充（ONS） 的临床疗效。方法全面检索PubMed 、EMbase、Web of Science、中国知网、万方数据库和SinoMed等数据库，搜索关于含Omega-3脂肪酸营养补充治疗肿瘤恶液质患者的随机对照试验。检索时间为2000年1月1日至2020年７月４日。对符合纳人标准的研究进行质量评价，按照 Cochmne5.1手册标准及改良的Jadad评分量表对纳人的研究进行偏倚风险评估和文献质量评价，最后应用RevMan5.3软件进行数据合并及meta分析。结果 初筛获得316篇文献，通过阅读标题和摘要进一步筛选获得54篇文献...

目的 采用口服乳清蛋白支持，观察其对恶性肿瘤恶液质患者血清清蛋白（ALB）、总 蛋 白（TR）、前 清 蛋 白（PAB）的影响。方法 选择2016年至2017年12月该院肿瘤科收治的恶性肿瘤恶液质患者66例作为研究对象，将其随机分为治疗组和对照组，各33例。所有患者入院后均予以常规营养支持，治疗组加口服补充乳清蛋白30g/d。对照组按照传统方法进行营养支持。两组治疗前和治疗后第10、20天检测ALB、TP、PAB水平，第20天检测T细胞亚群和体重改善情况。结果 两组治疗后ALB、TP、PAB水平均升高；治疗后两组ALB、PAB水平比较，差异均有统计学意义（P＜0.05）。Ｔ细胞亚群方面治...

Objective: To determine the relative effectiveness of dietary macronutrient patterns and popular named diet programmes for weight loss and cardiovascular risk factor improvement among adults who are overweight or obese. Design: Systematic review and network meta-analysis of randomised trials. ...

Short-time exposure to high levels of fine particles (particulate matter with an aerodynamic diameter ≤2.5 µm; PM2.5) may trigger respiratory disease, but this association has not been determined. The objective of this study was to evaluate and quantify the short-time exposure to fine particles o...

Background: Lack of research on the effects of gaseous pollutants (nitrogen oxides [NOx], sulfur dioxide [SO2], carbon monoxide [CO] and ozone [O3]) in the ambient environment on health outcomes from within low and middle income countries (LMICs) is leading to reliance on results from studies per...

Background Most prospective studies on the health effects of particulate ambient air pollution exposure have focused on high-income countries, which have much lower pollutant concentrations than low-income and middle-income countries (LMICs) and different sources of pollution. We aimed to inves...

Ozone is associated with adverse health; however, less is known about vulnerable/sensitive populations, which we refer to as sensitive populations. We systematically reviewed epidemiologic evidence (1988–2013) regarding sensitivity to mortality or hospital admission from short-term ozone exposure...

Background: Both air pollution and dementia are current and growing global issues. There are plausible links between exposure to specific air pollutants and dementia. Objective:To systematically review the evidence base with respect to the relationship between air pollution and later cognitive de...

To investigate short-term effects of ambient ozone exposure on mortality in Chinese cities, we conducted a meta-analysis of 10 effect estimates of 5 short-term studies, which reported associations between ambient ozone and mortality in Chinese mainland cities. And we estimated pooled effects by n...

Aims: Several meta-analyses of observational studies report a long-term correlation between air pollution and the risk of cancer, particularly lung carcinoma. The aim of this study was to review and quantify evidence for an association between air pollution and the risk of developing non-lung can...
