【摘要】目的探讨骨桥蛋白(OPN)联合血清CA125和CA199水平对子宫内膜异位症的诊断价值。方法2005年1月2008年12月采集45例子宫内膜异位症患者及45名健康妇女自愿捐赠的血清样品,分别采用ELISA法及化学发光法检测OPN、CA125、CA199水平。结果与健康妇女相比,子宫内膜异位症患者血清OPN和CA125、CA199含量明显升高(Plt;001)。重度组(美国生育学会分期Ⅲ、Ⅴ期)子宫内膜异位症患者OPN和CA125、CA199明显高于轻度组(Ⅰ、Ⅱ期)(Plt;001)。结论OPN、CA199可作为子宫内膜异位症诊断及病情监测的临床指标,联合CA125检测可提高其临床应用价值。

摘要:目的:研究胸腺瘤与前纵隔(血管前间隙)淋巴瘤的MSCT表现,提高对二者的诊断与鉴别诊断能力。方法:回顾性分析经手术病理证实的30例胸腺瘤与18例血管前间隙淋巴瘤MSCT表现,着重观察肿瘤的密度、形态及其与周围结构的关系。结果:30例胸腺瘤中,24例良性胸腺瘤与邻近大血管分界清晰,肿块表现 “D”字或反“D”字状,平扫CT值16~59 Hu,增强CT值20~110 Hu;6例侵袭性胸腺瘤边界不清,呈分叶状、不规则形,密度不均,平扫CT值23~42 Hu,增强CT值23~60 Hu。18例淋巴瘤中,单发于前上纵隔者6例,其余12例呈多结节、肿块状,侵入血管间隙生长,致大血管受压,增强扫描呈轻度强化,常伴有其它部位淋巴结增大。结论:MSCT能清晰显示胸腺瘤与前纵隔淋巴瘤的影像学表现特征,并能有效提高对二者的鉴别诊断。Abstract: Objective: To diagnosis and differentiate thymoma and malignant lymphoma in the anterior mediastinum on the basis of multislice CT (MSCT) imaging features. Methods:We retrospectively reviewed 30 cases with thymoma and 18 cases with malignant lymphoma proven by surgery and pathology.More attention was put on the density, morphology and relation with the surrounding structures of the tumors. Results: The CT manifestations of 30 cases of thymoma were shown as: For 24 cases of benign thymoma, the boundaries were clear, the shapes were “D” signs or contra“D” signs, CT attenuation value were 1659Hu and 20110Hu on unenhanced and contrastenhanced scanning. For 6 cases of malignant thymoma, the boundaries were unclear, the shapes were lobulated or irregular, the density was heterogeneous, CT attenuation value were 2342Hu and 2360Hu on unenhanced and contrastenhanced scanning. For 18 cases of malignant lymphoma, 6 cases were located at anterior mediastinum, 12 cases were nodes or multiple mass, enveloped the neighboring vessel structures, mildly enhanced on contrastenhanced scanning, and associated with enlargement of lymph nodes in other place. Conclusion: MSCT can display the imaging features of thymoma and anterior mediastinal lymphoma, and effectively differentiate thymoma and mediastinal lymphoma.
