目的 采用已有的4种国际非孕弥散性血管内凝血（DIC）诊断评分标准对产科DIC的诊断进行评估，探索更适合产科DIC诊断的“金标准”。 方法 选择2009年6月－2012年6月期间产科拟诊DIC的孕产妇为研究对象，用日本卫生福利部（JMHW）提出的JMHW、日本危重病协会（JAAM）提出的JAAM、国际血栓与止血委员会（ISTH）提出的ISTH显性和ISTH非显性4种诊断评分标准联合诊断和构建“金标准”，以此评价4种诊断标准对产科DIC诊断的特性。 结果 受试者工作特征（ROC）曲线分析显示ISTH非显性标准、ISTH显性标准、JMHW、JAAM的ROC曲线下面积分别为0.939、0.865、0.867、0.867，ISTH非显性标准灵敏度和特异度与“金标准”在不同诊断界值时较一致，同时优于其他3种诊断标准。 结论 ISTH非显性标准较适合作为临床产科DIC诊断，其对产科这一特殊发病人群的DIC诊断具有更科学的临床诊断价值。
Objective To explore maternal health services utilization in rural areas in Rongchang County, and to analyze the influencing factors. Methods Seven hundred pregnant women were enrolled by stratified cluster sampling. The data was analyzed in SAS 8.2. Results Ninety-five percent of pregnant women had an antenatal examination, 69.3% had it for 5 times or more, and 75.4% received checking in the earlier stage of pregnancy; 98.3% were delivered in hospital, 26.3% had postpartum visit 3 times or more, and 16.7% had been systematically managed. The main influencing factors of systematic management rate were family yearly income before pregnancy whether or not the patient participated in the new rural cooperative medical scheme, and the number of pregnancies. Conclusion The maternal systematic management rate in the county has yet to be improved. Health education to improve prenatal care and postnatal visit status should be strengthened, and women should be guided to participate in the new rural cooperative medical scheme.
