目的 开展卫生应急演练并总结经验,探讨演练在提高新发传染病应急处置能力中的作用。方法 以桌面演练和功能性演练为手段,在广州某三甲医疗机构开展演练活动,并对演练效果进行评价。结果 全院共51个科室开展新发传染病防控卫生应急演练,全院演练平均得分4.87。演练为新发传染病应急处置积累了实战经验,达到了锻炼队伍、提高能力的作用。结论 卫生应急演练是检验和提高新发传染病应急处置水平的重要手段,医疗机构通过推进演练活动的制度化、规范化和常态化,可促进新发传染病应急处置工作能力提升。

Objective To carry out health emergency exercises and summarize experiences, and to explore the role of exercises in improving emergency response capabilities for emerging infectious diseases. Methods Using tabletop exercises and functional exercises as means, the exercises were conducted in a tertiary class healthcare facilitie in Guangzhou, and the effects of the exercises were evaluated. Results A total of 51 departments in the hospital conducted health emergency exercises for the prevention and control of emerging infectious diseases, and the average score of the exercises was 4.87. The exercises accumulated actual combat experience for emergency treatment of emerging infectious diseases, and achieved the effect of training the team and improving the capabilities. Conclusion Health emergency exercise is an important mean to test and improve the emergency response capability of emerging infectious diseases. Healthcare facilities can promote the improvement of emergency response capabilities of emerging infectious diseases by promoting the institutionalization, standardization and normalization of exercise activities.

目的 探讨急性心肌梗死患者入院首次中心粒细胞/淋巴细胞比值(neutrophil/lymphocyte ratio,NLR)与院内主要不良心血管事件(MACE)发生的相关性。方法 回顾分析2016年1月—2016年12月入住我院的急性心肌梗死患者179例,分为发生院内不良事件组(n=46)和未发生组(n=133)。采用单因素及多因素Logistics回归分析评估NLR与MACE风险的相关性。结果 179例患者中,46例患者发生院内MACE。发生院内MACE组患者的淋巴细胞计数低于未发生组(P<0.05),NLR高于未发生组(P<0.05),发生院内MACE组患者入院时的心、肾功能较未发生组差(P<0.05)。单因素回归分析显示,NLR水平与院内MACE发病率相关(OR=1.079,95%CI:1.014～1.147, P＜0.05)。多因素logistic回归分析校正性别、年龄、高血压病史、糖尿病史、Killip II级以上、收缩压、入院首次白细胞、eGFR、超敏C反应蛋白、左室射血分数及多支病变后显示,NLR是院内MACE的独立危险因素(OR=1.182,95%CI:1.034～1.352,P＜0.05);此外,超敏C反应蛋白及LVEF<50也是院内MACE的独立危险因素(P＜0.05)。结论 入院首次高NLR与急性心肌梗死患者发生院内MACE相关,是患者发生院内MACE的独立危险因素。

Objective To explore the correlation between first neutrophil/lymphocyte ratio(NLR) and in-hospital major adverse cardiac events (MACE) in patients with in patients with acute myocardial infarction. Methods Total of 179 patients with acute myocardial infarction in Guangzhou First People's Hospital from Jan 2016 to Dec 2016 were enrolled. MACE was defined as malignant arrhythmia, recurrence of myocardial infarction, target vascular reconstruction, acute left heart failure, stroke, cardiac shock and death.Baseline data and in-hospital clinical adverse events were compared among two groups. All patients were divided into two groups:MACE(+) group and MACE(-) group. Univariate and multivariate logistic regression was used to assess the correlation between NLR and in-hospital MACE. Results In-hospital MACE occurred in 46(25.7%)patients. Univariate logistic analysis showed that NLR was strongly related with MACE incidence(OR=1.079,95%CI:1.014～1.147, P＜0.05). Multivariate logistic regression analysis found that after adjusting other traditional risk factors including female gender, age, hypertension,diabetes, overKillip II grade, systolic blood pressure,first white blood cells after admitted,basic renal dysfunction,Hs-CRP,LVEF and multivessel lesions. NLR was still a significant independent predictor of in-hospital MACE in patients with acute myocardial infarction. Additionally, hs-CRP and LVEF<50% were also associated with in-hospital MACE(P＜0.05). Conclusion NLR is the independent risk factor for in-hospital MACE occurrence in acute myocardial infarction at the early admission.
