Coccidioidomycosis is an endemic disease of the Western hemisphere. The cases in non-endemic areas are mostly imported. Determining a history of exposure is critical for performing the diagnosis of coccidioidomycosis, especially for cases occurring in a non-endemic area. In this study, a 71-year-old Chinese male presented to our hospital with chronic cough(More)
OBJECTIVE To investigate the pathogenic causes of community-acquired pneumonia (CAP) in adult patients in China, the relation of previous antibiotic use and the Pneumonia Patient Outcome Research Team (PORT) classification to microbial etiology, and the prevalence of drug resistance of common CAP bacteria. METHODS A prospective study was performed on 665(More)
Levofloxacin (LVFX), a fluoroquinolone agent, has a broad spectrum that covers Gram-positive and -negative bacteria and atypical pathogens. It demonstrates good clinical efficacy in the treatment of various infections, including lower respiratory tract infections (LRTIs) and urinary tract infections (UTIs). To evaluate the efficacy and safety of oral LVFX(More)
OBJECTIVE To investigate the prevalence and clinical outcome of right ventricular (RV) dysfunction among normotensive PE patients. METHODS Inclusion criteria included: (1) Confirmed PE at Sir Run Run Shaw Hospital from January 2001 to December 2004. (2) Normotensive. (3) Echocardiography done before therapy. RV dysfunction was assessed with(More)
Nkx2-1 (Nkx homeobox-1 gene), also known as TTF-1 (thyroid transcription factor-1), is a tissue-specific transcription factor of the thyroid, lung, and ventral forebrain. While it has been shown to play a critical role in lung development and lung cancer differentiation and morphogenesis, molecular mechanisms mediating Nkx2-1 cell- and tissue-specific(More)
OBJECTIVE to study the characteristics of volatile organic compounds (VOCs) in exhaled breath of lung cancer patients, and therefore to explore its use in the diagnosis of the disease. METHODS from February 2007 to September 2009, 55 patients with lung cancer, 21 patients with benign lung diseases and 30 healthy controls were enrolled in our study. The(More)
Glomus tumor is an exceedingly rare neoplasm that is derived from cells of the neuromyoarterial glomus or glomus body. It rarely occurs in the visceral organs where glomus body may be sparse or even absent, such as the stomach, intestines, mediastinum, and respiratory tract. It is unusual for a glomus tumor to demonstrate atypical or malignant(More)
OBJECTIVE To identify the volatile organic compounds (VOCs) in lung cancer tissue and lung cancer cell lines. METHODS The lung cancer tissue samples from 18 patients were cultured and 4 lung cell lines (A549, NCI-H446, SK-MES-1, BEAS-2B) were also included in the study. Air samples in the headspace of culture flasks were analyzed for VOCs with solid-phase(More)
OBJECTIVE The purpose of this study was to analyze the chest CT findings of immunocompetent patients with primary pulmonary cryptococcosis and to evaluate the utility of CT-guided percutaneous biopsy in the diagnosis. METHODS Chest CT scans of 12 immunocompetent patients with biopsy-proven primary pulmonary cryptococcosis were analyzed for the number of(More)
OBJECTIVE to highlight the clinical manifestation, histologic characteristics, diagnostic and therapeutic method of tracheal lobular capillary hemangioma (LCH). METHODS the clinical, auxiliary examinational and pathological data of two patients with tracheal LCH were presented, and relevant literatures were reviewed. RESULTS LCH is a polypoid form of(More)
