Mycobacterium tuberculosis-specific memory T cells in bronchoalveolar lavage of patients with pulmonary tuberculosis.

Background: Mycobacterium tuberculosis(MTB) most often infects the lungs and results in pulmonary tuberculosis(TB). MTB-specific memory T cells are able to respond quickly against antigens and help reduce the burden of pulmonary bacteria. The characteristics, function and chemotaxis axis of memory T cells in the lung remain unclear.

Application of Bronchoscopic TransParenchymal Nodule Access in tuberculous bronchial occlusion.

Bronchoscopic TransParenchymal Nodule Access (BTPNA) technology is mainly used for sampling or ablative treatment of lung parenchymal lesions that cannot be reached by bronchoscopy and its appendages, generally for palliative treatment of some lung tumors. We used BTPNA to treat a 32-year-old young woman with pulmonary tuberculosis and successfully perforated her occluded left main bronchus. Her left atelectasis was recovered, and a silicone stent was inserted to preserve the shape of the left main bronchus.

Application of potassium titanyl phosphate (KTP) laser delivered via bronchofiberscope in the treatment of endobronchial tuberculosis.

To explore the application of potassium titanyl phosphate (KTP) laser delivered via bronchofiberscope in the treatment of endobronchial tuberculosis. 36 patients with a diagnosis of endobronchial tuberculosis, with age ranging from 15 to 40 y were treated with KTP laser between Dec. 2002 and July 2004 (designated as treatment group).
