目的   探讨妊娠期糖尿病（GDM）患者载脂蛋白B（Apo-B）、载脂蛋白A1（Apo-A1）水平在分娩巨大儿中的预测价值。方法   选取2023年1月—2024年1月在珠海市第五人民医院建档并进行孕检、分娩的85例GDM患者，按照分娩的新生儿体质量情况分为分娩正常组55例（新生儿体质量＜4 000 g）和分娩异常组30例（新生儿体质量≥4 000 g）。比较两组孕妇一般资料及孕早期的Apo-B、Apo-A1、Apo-B/Apo-A1比值，采用受试者操作特征（ROC）曲线分析Apo-B、Apo-A1、Apo-B/Apo-A1对GDM患者分娩巨大儿的预测价值。结果   分娩异常组Apo-B水平、Apo_B/Apo_A1比值（1.05±0.15）g/L、（0.81±0.23）］高于分娩正常组（0.95±0.12）g/L、（0.65±0.18）］（t分别为3.357、3.544，P＜0.05）；Apo-A1水平［（1.29±0.26）g/L］低于分娩正常组［（1.47±0.23）g/L］（t=3.292，P＜0.05）；ROC曲线显示，Apo-B、Apo-A1水平及Apo-B/Apo-A1比值预测GDM患者分娩巨大儿的曲线下面积（AUC）分别为0.705、0.660、0.709，灵敏度分别为63.33%、63.33%、66.67%，特异度分别为72.73%、74.55%、76.36%，其中Apo-B/Apo-A1比值预测效能最高（P＜0.05）。结论  GDM患者分娩巨大儿与孕早期Apo-B升高、Apo-A1水平降低密切相关，监测患者孕早期的Apo-B、Apo-A1水平及Apo-B/Apo-A1比值有助于临床对分娩巨大儿进行预测。

      Objective  To explore the predictive value of apolipoprotein B（Apo-B）and apolipoprotein A1（Apo-A1）levels on delivery of macrosomia in patients with gestational diabetes mellitus（GDM）．Methods  From January 2023 to January 2024，85 patients with GDM who were filed in the hospital and received pregnancy examination and delivery were selected．According to the neonatal body mass，the patients were divided into 55 cases in normal delivery group（newborn birth weight ＜4 000 g）and 30 cases in abnormal delivery group（ newborn birth weight ≥4 000 g）．The general data and levels of Apo-B，Apo-A1 and Apo-B/Apo-A1 in early pregnancy were compared between the two groups．Receiver operating characteristic（ROC）curve was used to analyze the predictive value of Apo-B，Apo-A1 and Apo-B/Apo-A1 on delivery of macrosomia in GDM patients．Results  The Apo-B and Apo-B/Apo-A1 in abnormal delivery group were（1.05±0.15）g/L and（0.81±0.23），which were higher than（0.95±0.12）g/L and（0.65±0.18）in normal delivery group（t=3.357，3.544，P＜0.05）．While the level of Apo-A1 in abnormal delivery group，（1.29±0.26）g/L，was lower than（1.47±0.23）g/L in normal delivery group（t=3.292，P＜0.05）．ROC curve showed that the areas under the curve（AUC）of Apo-B，Apo-A1 and Apo-B/Apo-A1 in  predicting macrosomia in GDM patients were 0.705，0.660 and 0.709，and the sensitivities were 63.33%，63.33% and 66.67%，and the specificities were 72.73%，74.55% and 76.36%，respectively．Apo-B/Apo-A1 had the highest predictive efficiency（P＜0.05）．Conclusions  The delivery of macrosomia in GDM patients is closely related to the increase of Apo-B and the decrease of Apo-A1 in early pregnancy．Monitoring Apo-B，Apo-A1 and Apo-B/Apo-A1 in early pregnancy is helpful to predict the delivery of macrosomia．

目的 探究血清多配体蛋白聚糖-1（SCD-1）与可溶性血管内皮生长因子受体-2（sVEGFR-2）表达水平在老年慢性心力衰竭患者预后评估的判定价值。方法 选取2023年1月—2024年3月珠海市第五人民医院检验科收治的110例老年慢性心力衰竭患者,检测其血清SCD-1和sVEGFR-2水平,对患者进行随访调查,了解其再次由于心力衰竭住院、心源性死亡的情况。运用多因素Logistic回归分析,探究老年慢性心力衰竭患者预后影响因素。结果 Logistic回归分析显示,心功能分级（OR=3.433,95%CI：0.934~6.431）、B型脑钠肽升高（OR=2.462,95%CI：0.861~4.765）、血清SCD-1升高（OR=3.795,95%CI：0.972~6.894）、血清sVEGFR-2升高（OR=3.842,95%CI：0.942~6.912）为影响老年慢性心力衰竭患者预后不良的重要因素（P<0.05）;联合血清SCD-1和sVEGFR-2曲线下面积0.962与B型脑肽钠曲线下面积0.844,相较于单一SCD-1曲线下面积0.658、sVEGFR-2曲线下面积0.712明显偏高（P<0.05）。结论 经研究证实,老年慢性心力衰竭患者预后效果不理想,其血清SCD-1和sVEGFR-2监测水平异常升高,和老年慢性心力衰竭预后不佳存在关联性,可视为老年慢性心力衰竭患者判定预后效果的主要标志物。

Objective To investigate the prognostic value of serum syndecan-1（SCD-1）and soluble vascular endothelial growth factor receptor-2（sVEGFR-2）expression levels in elderly patients with chronic heart failure. Methods A total of 110 elderly patients with chronic heart failure admitted to our hospital were selected,with a time interval of January 2023 to March 2024．Serum SCD-1 and sVEGFR-2 levels were detected and follow-up investigations were conducted to understand their re hospitalization and cardiogenic death due to heart failure．Multiple logistic regression analysis was used to explore the prognostic factors affecting elderly patients with chronic heart failure. Results According to logistic retrospective analysis,heart function grading（OR=3.433,95%CI：0.934-6.431）,elevated B-type brain natriuretic peptide（OR=2.462,95%CI：0.861-4.765）,elevated serum SCD-1（OR=3.795,95%CI：0.972-6.894）,and elevated serum sVEGFR-2（OR=3.842,95%CI：0.942-6.912）were important factors affecting the poor prognosis of elderly patients with chronic heart failure,with differences P<0.05．The area under the curve of combined serum SCD-1 and sVEGFR-2 was 0.962,and the area under the curve of B-type brain peptide sodium was 0.844,which was significantly higher than that of a single SCD-1 curve of 0.658 and sVEGFR-2 curve of 0.712,with a difference of P<0.05. Conclusions Research has confirmed that the prognosis of elderly patients with chronic heart failure is not satisfied,and their serum SCD-1 and sVEGFR-2 monitoring levels are abnormally elevated,which is related to the poor prognosis of elderly patients with chronic heart failure．It can be regarded as the main biomarker for defining the prognosis of elderly patients with chronic heart failure．
