Background: Tuberculosis often presents on imaging in the form of a solitary nodule, sometimes accompanied by elevated CEA, which is clinically difficult to differentiate from lung cancer and prone to misdiagnosis.

Methods: Lung tissue taken by lung biopsy and sent for NGS and Xpert MTB/RIF finally led to the definitive diag-nosis of nodular foci in the upper lobe of the left lung caused by tuberculosis.

Results: Enhanced CT of the chest showed nodular foci in the upper lobe of the left lung. Initially the nodules were thought to be malignant, but after a series of tests, were finally confirmed to be tuberculosis.

Conclusions: In patients with lung disease, when chest imaging reveals a space-occupying lesion accompanied by an elevated CEA level, a comprehensive analysis of the type of lung disease, the patient's age, and comorbidities should be performed before final diagnosis to avoid misdiagnosis and delay in appropriate treatment.

Objectives: Natural fibrous mineral, asbestos, has been useful in industry for many centuries. In the 1960's, epidemiology had recognized the association between asbestos exposure and mesothelioma and the IARC designated all kinds of asbestos as Group 1 in 1987. However, various scientific enigmas remained regarding the molecular mechanisms of asbestos-induced mesothelial carcinogenesis.

Background: X-ray grating-based dark-field imaging can sense the small angle scattering caused by object's micro-structures. This technique is sensitive to the porous microstructure of lung alveoli and has the potential to detect lung diseases at an early stage. Up to now, a human-scale dark-field CT (DF-CT) prototype has been built for lung imaging.

Background: The hypobaric hypoxic atmosphere can cause adverse reactions or sickness. The purpose of this study was to explore the preventive effect and mechanism of human umbilical cord mesenchymal stem cells (hUC-MSCs) on acute pathological injury in mice exposed to high-altitude.

Methods: We pretreated C57BL/6 mice with hUC-MSCs via the tail vein injection, and then the mice were subjected to hypobaric hypoxic conditions for five days.
