本文总结了我院2016~2018信息化全面建设工作,包括机房、网络和应用系统建设,重点介绍实验室信息管理系统（LIMS）建设情况、经验和教训,以期为全国食品药品检验检测单位的信息化建设工作提供参考。     

前白蛋白变化率对肝衰竭预后的预测作用

目的探讨血清前白蛋白(PALB)变化率与肝衰竭预后的关系。方法回顾性分析98例肝衰竭患者的临床资料,对患者进行Child-Pugh分级,并把患者分为好转组与未愈组,收集住院期间初始及末次PALB及其他主要肝功能指标的数值,并计算出PALB及其他主要肝功能指标的变化率。结果入院时患者的初始PALB数值明显下降,且Child-Pugh分级越高,数值越低。好转组与未愈组患者的初始PALB数值相近,当血清PALB数值快速升高时,好转组人数明显多于未愈组;当数值下降时,好转组人数明显少于未愈组;当数值升高不明显时,未愈组与好转组差异无统计学意义,但未愈组人数要多于好转组。PALB变化率的敏感度最高,特异度较总胆红素、凝血酶原活动度、国际标准化比值变化率低,而ROC曲线下面积最大。结论肝衰竭患者初始PALB明显比正常值低,而且病情越重,血清中PALB数值越低,但患者预后与初始PALB无相关性,而与PALB变化率相关。大部分PALB快速升高者,预后好;大部分PALB下降或升高缓慢者,预后差。而且PALB变化率对于预后的预测价值要高于其他主要肝功能指标。     

胎儿超声心动图诊断左心发育不良综合征13例报道

目的:探讨应用胎儿超声心动图对左心发育不良综合征(HLHS),诊断方法及诊断价值。方法:对胎儿超声心动图检出的13例HLHS胎儿的超声资料与病理解剖结果对照,分析胎儿超声心动图诊断要点。结果:经病理证实为HLHS 13例,均与超声诊断结果一致,超声诊断正确率100%。13例HLHS患儿中,Ⅰ型2例(15.4%),Ⅱ型5例(38.4%),Ⅲ型2例(15.4%),Ⅳ型4例(30.8%)。超声提示13例均显示左、右心系统比例极端不对称,左心室小、发育不良,右心系统比例增大,主肺动脉内径比例失调,主肺动脉血流方向呈反向。结论:产前胎儿超声心动图作为一种安全、便捷、经济及有效的检查方法,对胎儿左心发育不良综合征的检出具有重要的价值。     

Hypo- and hyperglycemia predict outcome in patients with left ventricular dysfunction after acute myocardial infarction: data from EPHESUS

BackgroundHyperglycemia predicts death in cardiovascular disease, but intensive glucose-lowering strategies increase mortality rates in diabetes. The present analysis investigated the prognostic value of postadmission blood glucose (BG) concentration on clinical outcomes in high-risk patients with heart failure after acute myocardial infarction.Methods and ResultsA total of 6,496 patients from the Eplerenone Post–Acute Myocardial Infarction Heart Failure Efficacy and Survival Study (EPHESUS) were categorized into 4 groups by plasma glucose concentration: ≤4.5 mmol/L (hypoglycemia), 4.5–5.5 mmol/L (normoglycemia), 5.5–8.3 mmol/L (elevated glucose level), and >8.3 mmol/L (severe hyperglycemia). We evaluated the time to all-cause death (primary end point) and time to cardiovascular death or hospitalization (secondary end point). Hypo- and severe hyperglycemia were prevalent in 509 (8%) and 1,588 (24%) patients, respectively. There was a U-shaped relationship between BG level and incidence of all-cause death (11.8% in patients with normoglycemia vs 15.1% and 19.9% in those with hypo- and severe hyperglycemia; P < .001). The incidence of the secondary end point was increased only in hyperglycemic patients (36% vs 23% in normoglycemic patients; P < .001). In multivariate Cox regression analysis, hypoglycemia (hazard ratio [HR] 1.38, 95% confidence interval [CI] 1.06–1.81; P = .002) and severe hyperglycemia (HR 1.52, CI 1.27–1.83; P < .0001) proved to be strong predictors of all-cause death. There was no significant interaction between eplerenone treatment and blood glucose levels regarding clinical outcomes.ConclusionsIn heart failure after acute myocardial infarction, both hypo- and hyperglycemia at the postacute phase identify patients with increased risk of death during long-term follow-up.
