NCT00248443
The MiniMax® study is a multicenter randomized controlled study aimed at demonstrating that a combination of non-invasive diagnostic tools are as effective as fiberoptic bronchoscopy and bronchoalveolar lavage (FO-BAL) in performing the etiological diagnosis of acute respiratory failure in cancer patients.
NCT01295866
Nitric oxide (NO) was considered as a mediator of nasal inflammation and the measurement of nasal nitric oxide (nNO) may assist in the diagnosis of nasal inflammation. Few data exists comparing nNO with established, larger accepted reference standard for chronic rhinosinusitis (CRS) diagnosis. Moreover, the role of atopic status on nNO in nasal inflammatory diseases has not been reported. The aim of our study was to determine the value of nNO in patients with chronic nasal inflammation, and to assess the relationship between nNO and atopic status in these patients. A total of 131 randomized patients suffering form chronic nonallergic nasal inflammation and 20 healthy volunteers were finally recruited. nNO was measured by NIOX devices. Sinus computed tomography (CT) scan, nasal endoscope and nasal symptoms evaluation were used in the different diagnosis of chronic rhinitis (CR), CRS without nasal polyps (CRSsNP) and CRS with nasal polyps (CRSwNP). Atopic status was confirmed by skin prick test and serum IgE levels. Blood eosinophils were evaluated simultaneously. Relationships among nNO, various atopic characteristics and chronic nasal inflammation were evaluated.
NCT01293734
Bronchial asthma is a common disease and frequently encountered disease of respiratory apparatus. It has very complex mechanism and multiple inducing factors. This study will focus on a new Chinese therapy on Bronchial asthma, analyzing the treatment mechanism of internal and external use, based on Traditional Chinese Medicine (TCM) theory and clinical practice. The study will also investigate the efficacy of the Chinese drugs and treatments on Bronchial asthma, and provide an effective therapy for this disease.
