Prognostic Utility of Monocyte to High-Density Lipoprotein Ratio in Patients With Acute Coronary Syndrome: A Meta-Analysis

BackgroundThe monocyte to high-density lipoprotein ratio (MHR) has been used to predict adverse clinical outcomes in patients with acute coronary syndrome (ACS). This meta-analysis aimed to evaluate the prognostic utility of MHR in patients with ACS.Materials and MethodsWe comprehensively searched for relevant studies in Pubmed, Embase, CNKI, WanFang and VIP databases until March 12, 2019. Epidemiologic studies investigating the association between MHR and major adverse cardiovascular events (MACE) or all-cause mortality in patients with ACS were included. Pooled effect was expressed as risk ratios (RR) with 95% confidence intervals (CI) for the highest versus the reference lower MHR group.ResultsEight studies involving 6,480 patients with ACS were included and analyzed. Meta-analysis indicated that the highest MHR was significantly associated with higher risk of MACE (RR 1.65; 95%CI 1.36-2.02) and all-cause mortality (RR 2.61; 95%CI 1.29-4.89) after adjusting for the conventional confounders. The prognostic values of MACE with the highest MHR caused no significant changes in the in-hospital follow-up (RR 1.76; 95%CI 1.34-2.32) and >6 months follow-up (RR 1.68; 95%CI 1.08-2.62) subgroups. Furthermore, ST elevation myocardial infarction patients with the highest MHR had a 2.07-fold higher risk of in-hospital MACE (RR 2.07; 95%CI 1.52-2.80).ConclusionsElevated MHR is independently associated with an increased risk of MACE and all-cause mortality in patients with ACS. MHR may serve as a potential prognostic indicator for ACS prognosis.     

手术室药品管理质量评价指标体系的构建与应用

目的 构建手术室药品管理质量评价指标体系，提高手术室药品管理质量。 方法 基于2轮专家函询，确立手术室药品管理质量评价指标体系；针对评价指标进行培训与监测，比较干预1年后手术室药品管理质量。 结果 构建了包含3个一级指标、6个二级指标、29个三级指标的手术室药品管理质量评价指标体系。手术室护理人员药品知识考核合格率从70.07%上升至98.18%，手术室药品分类分区固定放置率、药品账物相符率及医护人员满意率显著提高，药品过期、变质发生率显著降低（均P＜0.05）。 结论 构建的手术室药品管理质量评价指标体系科学、实用，有利于手术室药品管理质量的提升。     

国外家庭医生签约服务及其对我国的启示

本研究在总结英国、美国、德国、澳大利亚等国家的家庭医生签约服务现状及其经验的基础上,结合我国在家庭医生签约过程中存在的问题,提出针对性的解决措施或建议。鉴于缺乏相关制度保障、财政支持不到位、家庭医生能力不足,未建立良好医患关系等问题,本研究指出应强化相关政策倾斜力度、增加相关经费投入、加强家庭医生队伍建设、建立良好医患关系等,探索适合中国特色的家庭医生签约服务模式。     

FNDC5 attenuates adipose tissue inflammation and insulin resistance via AMPK-mediated macrophage polarization in obesity

BackgroundObesity-induced chronic inflammation is critical in the pathogenesis of insulin resistance, and the recruitment and proinflammatory activation of adipose tissue macrophages (ATMs) is important for the development of this process. Here, we examined the effects of fibronectin type III domain-containing 5 (FNDC5) on inflammation and insulin resistance in high-fat diet-induced obese mice.Materials and MethodsMale wild-type (WT) and FNDC5^−/− mice were fed with standard chow (Ctrl) or high fat diet (HFD) for 20 weeks to induce obesity and insulin resistance. Firstly, effects of FNDC5 gene deletion on obesity, insulin resistance, macrophage accumulation and polarization and adipose tissue inflammation were determined in mice. Secondly, the macrophage polarity shift was further examined with flow cytometry in isolated stromal vascular fraction (SVF). Thirdly, the effects of exogenous FNDC5 on lipopolysaccharide (LPS)-induced macrophage polarization, inflammation and the underlying signaling mechanism were investigated in RAW264.7 macrophages and primary mouse peritoneal cavity macrophages (PMs). Finally, the therapeutic effects of FNDC5 overexpression were examined in HFD-induced obese WT and FNDC5^−/− mice.ResultsFNDC5 gene deletion aggravated obesity, insulin resistance, fat accumulation and inflammation accompanied with enhanced AMPK inhibition, macrophages recruitment and M1 polarization in mice fed with HFD. Exogenous FNDC5 inhibited LPS-induced M1 macrophage polarization and inflammatory cytokine production via AMPK phosphorylation in both RAW264.7 macrophages and PMs. FNDC5 overexpression attenuated insulin resistance, AMPK inhibition, M1 macrophage polarization and inflammatory cytokine production in adipose tissue of obese WT and FNDC5^−/− mice.ConclusionsFNDC5 attenuates adipose tissue inflammation and insulin resistance via AMPK-mediated macrophage polarization in HFD-induced obesity. FNDC5 plays several beneficial roles in obesity and may be used as a therapeutic regimen for preventing inflammation and insulin resistance in obesity and diabetes.
