卵巢扭转（OT）是女性常见急腹症之一,它可发生在任何年龄的女性,在儿童中也较为常见。OT是女童失去卵巢最常见的原因,临床上往往无法第一时间明确诊断,从而导致漏诊、误诊,这将会直接影响女性的内分泌及生殖功能,严重者甚至危及生命。虽然目前临床上普遍通过患者的临床表现及检查进行初步诊断,但多项研究显示,一些血液检验指标对于OT的诊断及与卵巢其他疾病的鉴别同样具有一定的帮助。因此,本文通过总结分析小儿OT的病因、临床表现、实验室检查、治疗及其相关诊断标志物,以提高临床医生对该病的认识。

Objective To evaluate the clinical significance of CT + MRI scans in diagnosis of primary liver cancer and prognosis evaluation after interventional therapy. Methods A total of 150 cases of patients with primary liver cancer admitted to our hospital from January 2019 to January 2021 were selected. They all received interventional treatment, and were examined by CT and MRI. The results of pathological examination were taken as the gold standard in this study to compare the diagnostic efficacy of CT, MRI and CT+MRI.Kappa value was used to compare the consistency of CT, MRI, CT+MRI scans with gold standard, and compared the detection rate of lesions after CT, MRI and CT+MRI interventional surgery. Results The diagnostic accuracy (98.67%), specificity (75.00%) and sensitivity (99.32%) of CT + MRI scans were higher than those of CT (86.00%, 25.00%, 87.67%) and MRI scans (90.67%, 91.78%, 50.00%),P<0.05 (which differences were statistically significant). The consistency of CT + MRI scans with gold standard was good (kappa value was 0.779), but the consistency of CT/MRI scans with gold standard were not satisfying (kappa value were 0.527, 0.596). The total detection rate of lesions after CT + MRI interventional surgery (12.00%) was higher than that of CT (2.00%) and MRI (4.00%, which P<0.05). Conclusion CT + MRI scans can improve the detection rate of lesions in patients with primary liver cancer after interventional therapy, and make up for the deficiency of only CT or MRI scans.

目的 探索两种常用免疫学指标—结核菌素试验(purified protein derivative skin test, PPD皮试)与结核分枝杆菌γ-干扰素释放试验(tuberculosis-interferon gamma release assay,TB-IGRA)对结核病的辅助诊断价值。方法 收集2017年1月—2021年1月于我中心门诊部就诊的疑似结核病患者资料,共171例,所有病例均行PPD皮试和外周血TB-IGRA。将病例分为结核病组(TB组)和非结核病组(非TB组)。TB组共98例,非TB组共73例。比较两组病例PPD皮试、TB-IGRA对结核病诊断的准确度、敏感度、特异度。结果 TB-IGRA对结核病诊断的准确度、敏感度和特异度分别为94.2%、93.9%和90.4%,PPD皮试对结核病诊断的准确度、敏感度和特异度分别为77.2%、84.7%和76.7%。TB-IGRA的准确度和特异度与PPD皮试比较差异有统计学意义(分别为χ²=20.034,P<0.05和χ²=5.176,P<0.05);TB-IGRA的敏感度高于PPD皮试,但两者比较差异无统计学意义(χ²=0.948,P>0.05)。2组间TB-IGRA结果、PPD皮试结果比较差异均具有统计学意义(分别为χ²=132.77,P<0.01和χ²=47.963 5,P<0.01)。结论 TB-IGRA和PPD皮试均具有良好的结核病辅助诊断价值;TB-IGRA的引进大大提高了诊断试验的准确度和特异度,但仍需要进一步探索其诊断标准以更好地为临床使用。

Objective To explore the auxiliary diagnosis value of two commonly used immunological indicators for tuberculosis, purified protein derivative skin test (PPD test) and tuberculosis-interferon gamma release assay (TB-IGRA). Methods A total of 171 cases of suspected tuberculosis patients who were treated in the outpatient department of our center from January 2017 to January 2021 were collected. All cases underwent PPD test and peripheral blood TB-IGRA. The cases were divided into tuberculosis groups (TB group) and non-tuberculosis group (non-TB group). There were 98 cases in the TB group and 73 cases in the non-TB group. The accuracy, sensitivity, and specificity of PPD test and TB-IGRA for tuberculosis diagnosis were compared between the two groups. Results The accuracy, sensitivity, and specificity of TB-IGRA for tuberculosis diagnosis were 94.2%, 93.9% and 90.4% respectively, which of PPD test for tuberculosis diagnosis were 77.2%, 84.7% and 76.7% respectively. The accuracy and specificity of TB-IGRA were statistically different from those of PPD test (χ²=20.034,P<0.05 and χ²=5.176,P<0.05, respectively). The sensitivity of TB-IGRA was higher than that of PPD test, but the difference was not statistically significant (χ²=0.948,P>0.05). The differences of TB-IGRA and PPD test results between the two groups were statistically significant (χ²=132.77,P<0.01 and χ²=47.9635,P<0.01). Conclusion Both TB-IGRA and PPD test had good auxiliary diagnostic value for tuberculosis; the introduction of TB-IGRA had greatly improved the accuracy and specificity of the diagnostic test, but it is still necessary to further explore its diagnostic criteria to better serve the clinical use.
