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 application and follow-up monitoring and diagnostic value of lung ultrasound (LUS) in elderly patients(≥75y) with novel coronavirus pneumonia (COVID-19). Methods Data of 25 COVID-19 elderly patients admitted to the Department of Internal Medicine from November 1, 2022 to January 15, 2023 were retrospectively analyzed and summarized. In addition to clinical data, dynamic monitoring of LUS was performed, and the results were compared with lung CT results. The examination results, as well as the prediction and impact on the course of disease were observed. Results LUS imaging indicated that patients had different degrees of interstitial lung injury, including discrete type B line (interstitial exudation) or fusion type B line (alveolar infiltration) and lung consolidation (alveolar collapse). With the improvement of the disease, the range of lung consolidation seen in LUS was reduced, the B-line was gradually sparse to dissipate, and the A-line appeared. Conclusions The results of LUS and chest CT in the same period are consistent. LUS examination is safe, simple, reproducible, and can be monitored dynamically in real time. It can be used as a primary screening method, and also be used in special patients to assist clinical treatment decision-making.

Objective To analyze and compare the clinical features of patients with pulmonary involvement of Whipple disease and primary treated bacteriological negative pulmonary tuberculosis,so as to improve the recognition,diagnosis and differentiation ability of pulmonary involvement of Whipple disease．Methods Clinical features of Whipple disease with pulmonary involvement were investigated by retrospectively collecting 20 cases as a case group,comparing with 56 randomly selected patients with primary treated bacteriological negative pulmonary tuberculosis as a control group during the same period．Results The case group had a significantly higher proportion of older patients（>37 years）,acute or subacute disease courses than the control group （P<0.05）．On CT imaging,in terms of lesion distribution,the proportion of cases with lesions in the lower lobe was significantly more in the case group than in the control group（P<0.05）,and the ratio of cases with lesions in the upper lobe was considerably less than in the control group（P<0.05）．Regarding morphology,significantly more of the case group showed reticular lesions and interstitial pneumonia than the control group（P<0.05）．Significantly fewer of the case group showed cavities,fibrous bands,solid shadows,nodular shadows,tree-bud signs,and enlarged hilar lymph nodes than the control group（P<0.05）．No statistically significant differences existed between the two groups in gender,combined immunocompromising diseases,cough,sputum,fever,coughing up blood,arthralgia or diarrhea. At the same time,the differences of gender,combined immunocompromised disease,cough,sputum,fever,coughing up blood,arthralgia,and diarrhea were not statistically significant．The metagenomic sequencing of alveolar lavage fluid in the case group revealed Tropheryma whipplei as the sole pathogenic bacteria in 19 cases（95%）or the primary pathogenic bacteria in 1 case（5.00%,combined TB 1 sequence）．In contrast,metagenomic sequencing of alveolar lavage fluid in the control group detected Mycobacterium tuberculosis complex as the sole or primary pathogenic bacteria in 21 cases（37.5%）,TB-RNA（+）in 18 cases and TB-LAMP（+）in 15 cases．Conclusions Clinical presentation in Whipple disease can be of an acute or subacute course,preferably in middle-aged and older men,with fever or/and respiratory symptoms,either with or without diarrhea and arthralgia．Its pulmonary imaging dominates with reticular,interstitial pneumonia changes in the lower lungs,which can involve the lungs alone in the disease．At the same time,the clinical symptoms are highly similar to those patients with primary treated bacteriological negative pulmonary tuberculosis．Therefore,it is vital to complete bronchoscopy and metagenomic sequencing of alveolar lavage fluid as soon as possible for early and rapid diagnosis of this Whipple disease．Treatment with sensitive antibacterial drugs can result in significant improvement and save patients' lives．
