Was presented in 12 cases (24%) by bacterial isolation. By in-situ hybridization, PCV2 signals were chiefly distributed in interstitial and necrotic lesions, and the positive signals could be found in macrophages-like cells and necrotic debris. PRRSV signals were mainly located at interstitial lesions and alveolar wall, and the positive signals could be found in macrophages-like cells and epithelial cells of alveoli. Swine influenza virus could be found in interstitial and necrotizing lesions, and the signals could be found in macrophages-like cells, and epithelial cells of terminal bronchiole and alveoli.

The superficial microvascular networks were sparser, while the subpleural microvascular networks were denser. The superficial blood vessels and the interlobular blood vessels were mutual transitional, and the anastomosing between the superficial blood vessels with the subpleural vessels. According to the branching sequence of the subpleural arteriole, it could be divided into the arteriole, terminal arteriole, precapillary arteriole and capillary in turn. The subpleural capillary networks were mainly web-like, while small holes were also found on the cast. The honeycomb vascular networks were various in size and form at a low magnification. The outline of alveolus, alveolar sac, alveolar duct and respiratory bronchiole and terminal bronchiole, made of microvascular networks, could be found in the cut surface.

Results 6 patients with PAP presented with ground-glass opacification of the bilateral lungs on HRCT. Typical chest HRCT scan showed "map-like" lesions in 3 cases and "cobble stone-like" lesions in 3 cases. Multifocal consolidative opacities in the lungs were seen on HRCT in 3 cases. Lung biopsies from 6 patients with PAP revealed a prominent positive periodic acid-Schiff intra-alveolar exudates. There were normal alveolar spetasis in 3 patients while interstitial thickening, fibroblast hyperplasia, interstitial fibrosis in the others.

The results showed that:(1) In COPD group the alveolar walls were broken. The average area of alveolars was 2.46 times as big as the control group, and the average diameter was 1.42 times as compared with the control group. As the diameter of bronchioles was less than 100μm and 100～200μm respectively, the average area of smooth muscle in bronchioles increased to 3.06-fold and 2.13-fold respectively. By electron microscopic, the proportion of Clara cells of respiratory bronchioles in COPD group decreased, the Clara cells were denaturalized, the proportion of Clara cells containing low density secretory granules increased. The airway resistance was 1.84 times while the dynamic compliance was only 70.45% comparing with the control group.
