目的 探索胸部CT值在胸腔积液鉴别诊断的价值。方法 81例胸腔积液患者纳入本研究,胸腔积液分为渗出液、漏出液、恶性胸腔积液及良性胸腔积液。建立平均CT值的ROC曲线,计算曲线下面积。结果 81例胸腔积液患者中59例为渗出液,22例为漏出液;恶性胸腔积液33例,良性胸腔积液48例。渗出液组平均CT值(16.68±6.76)Hu高于漏出液组(5.50±3.42)Hu(P<0.000 1)。ROC曲线分析结果显示,胸腔积液平均CT值对区分渗出液和漏出液具有较高的准确性(曲线下面积为0.944 5)。当最佳界值为≥9.99 Hu时,其敏感度为88.14%,特异度为90.91%;恶性胸腔积液组平均CT值(15.38±7.29)Hu与良性胸腔积液组平均CT值(12.45±8.03)Hu没有差异(P=0.098 1)。结论 在胸腔积液的鉴别诊断过程中,胸部CT的CT值在鉴别漏出液及渗出液中有一定的价值,但尚不能用于鉴别良性及恶性胸腔积液。

Objective To explore the value of chest CT value in the differential diagnosis of pleural effusion. Methods A total of 81 patients with pleural effusion were included in this study, including exudate, transudate, malignant pleural effusion and benign pleural effusion.The ROC curve of average CT value was established and the area under the curve was calculated. Results Among 81 patients with pleural effusion, 59 cases were exudative, 22 cases were transudative, 33 cases were malignant pleural effusion and 48 cases were benign pleural effusion.The mean CT value of the exudate group, (16.68±6.76) Hu, was significantly higher than (5.50±3.42) Hu of the transudate group (P<0.000 1).ROC curve analysis showed that the mean CT value of pleural effusion had high accuracy in distinguishing exudate from transudate (area under the curve was 0.9445).When the cut-off value for exudative effusion was over 9.99 Hu, the sensitivity and specificity were 88.14% and 90.91%, respectively.The mean CT value of malignant pleural effusion group, (15.38±7.29) Hu, was not significantly different from (12.45±8.03) Hu of benign pleural effusion group (P=0.098 1). Conclusions In the differential diagnosis of pleural effusion, the chest CT value can be used to identify transudate and exudate, but not benign and malignant pleural effusion.

目的 研究结核感染T细胞斑点试验(T-SPOT.TB)技术联合胸水腺苷脱氨酶(ADA)在结核性胸膜炎中的诊断价值。方法 在研究中选取2016年1月—2018年12月在梅州市人民医院呼吸内科和全科医学科住院的60例结核性胸膜炎患者作为研究对象,对所有患者均进行血T-SPOT.TB、胸水ADA检查,比较血T-SPOT.TB、胸水ADA及胸水ADA联合血T-SPOT.TB检查三种检测方式的诊断符合率、误诊率、漏诊率、阳性预测值、阴性预测值、准确性、特异度、敏感度。结果 胸水ADA、血T-SPOT.TB以及血T-SPOT.TB联合胸水ADA检测方式的诊断符合率分别为75%、80.00%、93.33%,联合检测方式的诊断符合率高于单一检测方式的诊断符合率(P＜0.05)。血T-SPOT.TB联合胸水ADA检测方式的误诊率、漏诊率分别为0.00%、1.72%,低于胸水ADA、T-SPOT.TB检测方式(P＜0.05);血T-SPOT.TB联合胸水ADA检测方式的阳性预测值、阴性预测值分别为100.00%,67.78%,联合检测方式的阴性预测值高于其单一检测方式(P＜0.05)。T-SPOT.TB联合胸水ADA检测方式的特异度及敏感度分别为98.79%、97.87%,联合检测方式的敏感度高于其单一检测方式(P＜0.05)。血T-SPOT.TB检测方式与胸水ADA检测方式仅在特异度方面不存在统计学差异(P＞0.05)。结论 在对结核性胸膜炎患者进行诊断时,血T-SPOT.TB联合胸水ADA具有较高的诊断价值,值得应用。

Objective To investigate the diagnostic value of t-spot test (T-SPOT.TB) combined with adenosine deaminase (ADA) in tuberculous pleuritis. Methods 60 patients with tuberculous pleurisy hospitalized in the departments of respiratory medicine and general practice of Meizhou People's Hospital between January 2016 and December 2018 were enrolled in the study. All the patients were examined by blood T-SPOT.TB and ADA. The diagnostic coincidence rate, false positive rate,false negative rate, positive predictive value, negative predictive value, accuracy, specificity and sensitivity of the three detection methods of T-SPOT.TB, ADA, and T-SPOT.TB combined with ADA were also analyzed. Results The diagnostic coincidence rate of ADA, T-SPOT.TB and T-SPOT.TB combined with ADA was 75%, 80.00% and 93.33%, respectively. The diagnostic coincidence rate of the combined test was higher than that of the detection method (P<0.05). The misdiagnosis rate and missed diagnosis rate of blood T-SPOT.TB combined with ADA were 33.3% and 1.75%, respectively. The positive predictive value and negative predictive value of blood T-SPOT.TB combined with ADA test were 98.2% and 66.6%, respectively. The negative predictive value of combined T-SPOT.TB combined with ADA test was higher than that of the single test (P<0.05). The specificity and sensitivity of the T-SPOT.TB combined with ADA were 98.79% and 97.87%, respectively, and the sensitivity of the combined test was higher than that of the single test (P<0.05). Conclusion Blood T-SPOT.TB combined with pleural effusion ADA has higher diagnostic value in patients with tuberculous pleurisy and is worthy of clinical application.

Objective To investigate the expression of Napsin A, TTF-1 and CK7 in paraffin cells block of malignant pleural effusion and their diagnostic value for lung adenocarcinoma. Methods Immunohistochemistry of Napsin A, TTF-1, CK7, serum and pleural fluid CEA were collected from patients with malignant pleural effusion. The patients were divided into lung adenocarcinoma group and non-lung adenocarcinoma groups according to tissue source. The expression of Napsin A, TTF-1, CK7, CEA and the levels of serum and CEA in pleural fluid were compared and their diagnostic value was calculated. Results The positive expression of Napsin A (83.9% vs 16.1%, P<0.001), TTF-1 (93.5% vs 6.5%, P<0.001) and CK7 (98.1% vs 1.9%, P<0.001) in malignant pleural effusion caused by lung adenocarcinoma were higher compared to other tumors. The sensitivity and specificity of Napsin A were 83.9% and 93.9%,the sensitivity and specificity of TTF-1 were 93.5% and 90.9%, and those of CK7 were 98.1% and 42.4%; which were higher than those of serum CEA (69.7% and 58.5%) and pleural fluid CEA (69.0% and 66.7%) respectively. Conclusion Napsin A, TTF-1 and CK7 are of high value in the diagnosis of malignant pleural effusion caused by lung adenocarcinoma from other tumors.

目的 探讨胸苷激酶1活性检测在胸腔积液鉴别诊断中的敏感度及特异度。方法 回顾性分析诊断明确的肺炎旁胸腔积液、结核性胸腔积液、癌性胸腔积液患者的临床资料,收集并检测三组患者胸腔积液标本中胸苷激酶1活性并进行比较。结果 三组胸腔积液胸苷激酶1含量分别为: 肺炎旁胸腔积液组: (1.18±0.73)pmol/L、结核组活性(1.31±0.64)pmol/L、癌性组(2.07±1.47)pmol/L。统计分析显示癌性组胸苷激酶1含量高于肺炎旁胸腔积液组及结核组,差异有统计学意义,而肺炎旁组与结核组胸苷激酶1含量无统计学差异。在诊断价值分析方面,当胸苷激酶1≥1.28 pmol/L时支持癌性胸腔积液诊断,但是当胸苷激酶1＜1.28 pmol/L时,无法鉴别肺炎旁和结核性胸腔积液。因此,胸苷激酶1对于癌性胸腔积液的诊断价值较好,对肺炎旁胸腔积液和结核性胸腔积液鉴别诊断效能差。临床可考虑与其他指标,如降钙素原、腺苷脱氨酶等指标联合诊断。结论 胸腔积液胸苷激酶1含量在癌性胸腔积液与非癌性胸腔积液的鉴别诊断中有较好诊断价值。

Objective To investigate the of thymidine kinase 1in differential diagnosis of pleural effusion. Methods A retrospective analysis of thymidine kinase1 activity in the parapneumonic pleural effusion and tuberculous pleural effusion and malignant pleural effusion were conducted. Results The thymidine kinase 1 of this three groups are respectively: parapneumonic group (1.18±0.73pmol/L), tuberculosis group (1.31±0.64pmol/L), and cancer group (2.07±1.47pmol/L). It was shown that the activity of thymidine kinase 1 in cancer group was higher than that of inflammation group and tuberculosis group, the difference was statistical significance, but there was no significant difference between parapneumonic group and tuberculosis group. It supported the diagnosis of malignant pleural effusion when thymidine kinase 1 was greater than or equal to 1.28pmol/L, but when the thymidine kinase 1 was less than 1.28pmol/L, it was impossible to distinguish parapneumonic pleural effusion and tuberculous pleural effusion. Therefore, the diagnosis efficiency of thymidine kinase 1 in malignant pleural effusion is well, but the diagnosis efficiency of thymidine kinase 1 in parapneumonic pleural effusion and tuberculous pleural effusion is not well. Conclusion The diagnosis efficiency of thymidine kinase 1 in malignant pleural effusion and non-malignant pleural effusion is well.
