目的探讨维生素K缺乏或拮抗剂诱导的蛋白质(protein induced by vitamin K absence or antagonist-Ⅱ,PIVKA-Ⅱ)、甲胎蛋白(α-fetoprotein,AFP)、甲胎蛋白异质体L3(α-fetoprotein heterogeneity-L3,AFP-L3)、癌胚抗原(carcinoembryoni...目的探讨维生素K缺乏或拮抗剂诱导的蛋白质(protein induced by vitamin K absence or antagonist-Ⅱ,PIVKA-Ⅱ)、甲胎蛋白(α-fetoprotein,AFP)、甲胎蛋白异质体L3(α-fetoprotein heterogeneity-L3,AFP-L3)、癌胚抗原(carcinoembryonic antigen,CEA)及不同组合模式在转移性肝细胞癌诊断中的应用及评分模型的构建。方法收集2019年1月至2022年7月我院283例肺癌、肠癌患者的血清,根据是否发生肝转移分为试验组(发生肝转移,n=70)和对照组(未发生肝转移,n=213),检测血清肿瘤标记物PIVKA-Ⅱ、AFP、AFP-L3、CEA的水平。比较各指标及其不同组合对转移性肝细胞癌筛查的敏感度、特异度,并绘制ROC曲线。通过单因素和多因素分析转移性肝细胞癌的独立影响因素,建立转移性细胞癌预测模型并验证。结果与对照组相比,试验组患者PIVKA-Ⅱ、AFP、AFP-L3、CEA的水平显著升高,差异有统计学意义(P<0.05)。两组在结肠息肉、脂肪肝、肿瘤大小、阳性淋巴结数目等方面比较,差异有统计学意义(P<0.05)。PIVKA-Ⅱ、AFP、AFP-L3、CEA、患有结肠息肉、脂肪肝、肿瘤≥5 cm、有阳性淋巴结是转移性肝细胞癌的独立危险因素(P<0.05)。在不同的组合指标中,PIVKA-Ⅱ+AFP+AFP-L3+CEA组合在敏感度和特异度等参数之间可达到相对最佳的平衡。对进入回归方程的指标进行风险评分,其中患有结肠息肉、患有脂肪肝、肿瘤大小≥5 cm、PIVKA-Ⅱ≥40 mAU/mL、AFP≥8.3 ng/mL、AFP-L3≥10%、CEA≥5.7 ng/mL七项指标分别设定为2、2、2、3、3、1.5、3.5分。总分在1.5~17分,根据百分位数进行评分分级,低危组<7分,中危组7~12.5分,高危组>12.5分,结果显示随着评分增加,转移性肝细胞癌风险增加。结论PIVKA-Ⅱ+AFP+AFP-L3+CEA组合在敏感度和特异度等参数之间可达到相对最佳的平衡,依据转移性肝细胞癌风险预测模型制定的评分标准有良好的预测性。展开更多

APACHEⅡscore 24 h and 72 h after entering ICUs predicted mortality with an area under the ROC curve（AUC） standing respectively at 0.919 and 0.9SS.Arterial blood lactate clearance rate 12 h, 24 h,48 h and 72 h after entering ICUs predicted mortality with an area under the ROC curve （AUC） at 0.918,0.918,0.909 and 0.991,respectively.Conclusions:APACHEⅡscore applied in combination with arterial blood lactate clearance rate is of clinical significance in assessing the prognosis of ARDS patients.展开更多
