This study is to evaluate the expression of biological markers in induced sputum and peripheral blood T lymphocytes of patients with combined pulmonary fibrosis and emphysema (CPFE). The features of CPFE would be observed, including pulmonary function tests and fractional exhaled nitric oxide （FENO）.
A new disease including concomitant upper-lobe emphysema and lower-lobe fibrosis in radiology has been defined as (combined pulmonary fibrosis and emphysema, CPFE). CPFE has distinct clinical characteristics with the emphysema and the pulmonary fibrosis, including gender, age, clinical manifestation, pulmonary function tests and prognosis.
Normally Th1/Th2 is balanced. However, patients with emphysema had a significantly higher expression of Th1. On the other hand, higher expression of Th2 is involved in the development of pulmonary fibrosis. The expressions of Th1 and Th2 were proved to play a central role in pathogenesis of emphysema and pulmonary fibrosis, while are still unknown in patients of combined pulmonary fibrosis and emphysema. The study would observe the Th1/Th2 expression, pulmonary function tests , fractional exhaled nitric oxide （FENO）and other features in CPFE patients.

Pulmonary fibrosis is observed in a substantial number of patients with ANCA-associated vasculitis (AAV), 15% in a recent German series, and may be more frequent in Asian populations. ANCA are usually...
Dihydroartemisinin has been shown to inhibit the development of pulmonary fibrosis in rats, but its mechanism has yet to be elucidated. This study aimed to determine the mechanisms of dihydroartemisin...
Two genome-wide association studies and one sequencing study have coincidently reported significant associations of single nucleotide polymorphisms (SNPs) in the desmoplakin (DSP) gene with the risk o...
Dyskeratosis congenita (DC) is a rare inherited disease characterized by the classical mucocutaneous triad. Pulmonary fibrosis, bone marrow failure, and solid tumors are the main causes of mortality i...
Epithelial-mesenchymal transition (EMT) plays a pivotal role in idiopathic pulmonary fibrosis (IPF). In bleomycin-induced pulmonary fibrosis mice, we observed that inhibition of mTOR (mammalia target ...
A group of interstitial lung diseases with no known etiology. There are several entities with varying patterns of inflammation and fibrosis. They are classified by their distinct clinical-radiological-pathological features and prognosis. They include IDIOPATHIC PULMONARY FIBROSIS; CRYPTOGENIC ORGANIZING PNEUMONIA; and others.
A process in which normal lung tissues are progressively replaced by FIBROBLASTS and COLLAGEN causing an irreversible loss of the ability to transfer oxygen into the bloodstream via PULMONARY ALVEOLI. Patients show progressive DYSPNEA finally resulting in death.
A common interstitial lung disease of unknown etiology, usually occurring between 50-70 years of age. Clinically, it is characterized by an insidious onset of breathlessness with exertion and a nonproductive cough, leading to progressive DYSPNEA. Pathological features show scant interstitial inflammation, patchy collagen fibrosis, prominent fibroblast proliferation foci, and microscopic honeycomb change.
A diverse group of lung diseases that affect the lung parenchyma. They are characterized by an initial inflammation of PULMONARY ALVEOLI that extends to the interstitium and beyond leading to diffuse PULMONARY FIBROSIS. Interstitial lung diseases are classified by their etiology (known or unknown causes), and radiological-pathological features.
Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.
