目的 分析谷草转氨酶（AST）、胆碱酯酶（CHE）、糖类抗原125（CA125）以及甲胎蛋白（AFP）对肝硬化患者的诊断效能。方法 选择70例肝硬化患者为观察组研究对象,另取70例同期健康体检者为对照组。两组研究对象均接受生化检验、肿瘤标志物检验。对比两组研究对象的AST、CHE、CA125、AFP检测结果,分析上述指标对肝硬化患者的诊断效能。结果 观察组肝硬化患者的CHE低于对照组,AST、CA125与AFP高于对照组（P<0.05）;AST与CHE在肝硬化诊断中具有良好的灵敏度、特异度;CA125联合AFP的灵敏度、特异度、符合率均高于CA125或AFP单独检验（P<0.05）。结论 AST、CHE、CA125、AFP在肝硬化患者临床诊断中具有良好的应用表现,是反映患者肝硬化病情进展的重要参考指标。

Objective To analyze the diagnostic efficacy of aspartate aminotransferase（AST）,cholinesterase（CHE）,carbohydrate antigen 125（CA125）,and alpha fetoprotein（AFP）in patients with liver cirrhosis．Methods A total of 70 patients with liver cirrhosis were included in the observation group as the study subjects,and 70 healthy individuals who underwent physical examinations during the same period were selected as the control group．Both groups of research subjects underwent biochemical testing and tumor marker testing．The AST,CHE,CA125,and AFP detection results of two groups of research subjects were compared,and the diagnostic effect of the above indicators on patients with liver cirrhosis were analyzed．Results The CHE test results of patients with liver cirrhosis in the observation group were significantly lower than those of healthy individuals undergoing physical examination,and the AST,CA125,and AFP test results were higher（P<0.05）．AST and CHE had good sensitivity and specificity in the diagnosis of liver cirrhosis．The sensitivity,specificity and coincidence rate of CA125 combined with AFP were higher than those of CA125 or AFP alone．Conclusions AST,CHE,CA125,and AFP have good clinical application performance in the diagnosis of liver cirrhosis patients,and are important reference indicators reflecting the progression of liver cirrhosis in patients．

目的 探讨胎儿颈部软组织(NT)超声检查联合血清甲胎蛋白(AFP)水平检测对产前胎儿神经管畸形诊断中的应用价值。方法 选取684例我院2018年4月—2021年4月接受产前检查的孕妇,所有孕妇分别采用NT超声检查、血清AFP水平检查,以引产结果为“金标准”,比较NT超声、血清AFP水平及联合检查诊断结果、诊断效能及对不同类型神经管畸形诊断符合率的影响。结果 经引产结果显示共48例神经管畸形胎儿;经NT超声检查共36例神经管畸形胎儿;经血清AFP水平检查共34例神经管畸形胎儿;经联合检查共47例神经管畸形胎儿;与NT超声、血清AFP水平单独检查相比,联合检查灵敏度89.58%、准确率98.68%、阴性预测值99.22%较高,漏诊率10.42%较低(P＜0.05);与NT超声、血清AFP水平单独检查相比,联合检查对于脑膨出、隐形脊柱裂胎儿检出率较高(P＜0.05)。结论 NT超声检查、血清AFP联合诊断准确率显著高于单独检查,可有效提高诊断效能,为临床筛查胎儿神经管畸形提供有效手段。
