Objective To investigate the value of radial probe endobronchial ultrasound (RP-EBUS)guided multi-dimensional combined examination in the diagnosis of peripheral lung cancer. Methods A retrospective analysis of 74 patients with peripheral lung cancer which were diagnosed in Foshan Second People's Hospital from September 2019 to December 2021 was carried out. RP-EBUS guided biopsy, brushing biopsy, bronchus alveolar lavage cytology and DNA methylation detection results were analyzed to obtain the positive diagnosis rate and influencing factors. Results The positive rates of RP-EBUS guided biopsy, brushing biopsy, bronchus alveolar lavage cytology and methylation for peripheral lung cancer were 52.7%, 47.3%, 45.9% and 51.4%, respectively. The positive rate of RP-EBUS guided multi-dimensional combined detection was 71.6%, which was significantly higher than single detection (P<0.05). The positive rate of RP-EBUS multi-dimensional combined examination in lesions diameter ≥30 mm was higher than that of lesion diameter ＜30 mm (82.9% vs 57.6%, P<0.05). The positive rate of RP-EBUS guided multi-dimensional combined group in the upper lobe, middle lobe/lingual lobe, and lower lobe of the lung were 69.7%, 66.7% and 76.9%, respectively, with no significant difference (P>0.05). The positive rate of ultrasound detected lesion in combined group was higher than that of undetected lesions (76.9% vs 33.3%, P<0.05). The ultrasound images of solid center lesions had higher positive rates than that of non solid center lesions (86.0% vs 59.1%, P<0.05). Conclusions RP-EBUS guided multi-dimensional combined examination has a higher positive rate for diagnosis of peripheral lung cancer. The positive rate of diagnosis are related to the size of the lesion, whether the lesion is detected by ultrasound and the characteristics of the ultrasound image of the lesion, but not related to the location of the lesion.

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.

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.
