Three of them were diagnosed as sarcoidosis. Two were pulmonary alveolar proteinosis. One with usual interstitial pneumonia, one with bronchialitis obliterous and organizing pneumonia, one with nonspecific pneumonia, one with Castleman's disease, one with pulmonary lymph angioleiomyomatosis, two with bronchioalveolar carcinoma, one as rheumatoid pulmonary fibrosis complicated with pulmonary squamatous cancer and locally metastas is in lungs, two as pulmonary lymphangitic carcinomatosis, one as lung squamatous cancer with pulmonary lymphangitic metastasis, and one with primary pulmonary paraganglioma.

结果 17例患者均获病理确诊，其中结节病3例，肺泡蛋白沉积症2例，普通型间质性肺炎1例，闭塞性细支气管炎伴机化性肺炎1例，非特异性间质性肺炎1例，Castleman病1例，淋巴管平滑肌瘤病1例，肺泡细胞癌2例，类风湿性关节炎肺间质纤维化合并肺鳞癌伴肺内多发转移1例，肺淋巴管癌2例，肺鳞癌伴肺内淋巴管转移1例，肺原发性副神经节细胞瘤1例。

The expressive level of ICAM–1, and its receptors of CD11b and CD18 were first detected after 24 hours infection in bronchial alveolar epithelial cells, bronchopulmonary capillary endothelial cells, and iinfiltrativing lymphomonocyte and monocytes, and reached were the peaks 4 days after infection.

研究发现：实验组小鼠肺组织中ICAM-1及其受体表达含量在攻毒后1d即开始升高，第4天达高峰。

A tooth is a significant organ for manducation and phonation; inferior alveolar nerve is one of the most important sensory nerves in maxillofacial region

牙齿作为重要的咀嚼、发音器官，下牙槽神经作为口腔颌面部重要的感觉神经之一，在颌面部创伤救治过程中均不可忽视。

Res ults: The maxillary central incisor was similar to the maxillar y lateral incisor in stress distribution. The highest stresses were observed in the root surface, the liwest in the periodontal ligament, the alveolar bone between them .

结果：上颌中、侧切牙的应力分布基本相同；上颌中、侧切牙及其支持组织的应力分布不均匀，牙根部受应力最大，牙槽骨次之，牙周膜最小。

Medicines for systemic osteoporosis are effective in ameliorating maxillomandibular bone structure, delaying alveolar bone resorption and promoting new bone formation.

针对全身骨质疏松治疗的药物能有效改善颌骨骨质结构，减缓牙槽骨吸收，促进新骨形成。

The thickness of alveolar wall, the areas of mesenchyma in lung tissue were measured by HE staining. Immunohistochemical evaluation was to detect the expression of TNF-α, TGF-β1, FN protein.

灌药后第7、14、28天分组处死动物，提取肺组织，HE染色行肺泡炎、肺纤维化程度分级及免疫组化测定肺组织TNF-α、TGF-β_1、FN蛋白表达。

The positive p38 MAPK cells in LPS injury groups increased obviously than those in the control groups (P.01), and were mainly distributed in infiltrative inflammatory cells, airway epithelial cells, alveolar epithelial cells and pleura mesepithelial cells.

LPS致伤组p38 MAPK阳性细胞较对照组明显增多(P.01)，主要分布于浸润的炎症细胞、气道上皮细胞、肺泡上皮细胞、胸膜间皮细胞和血管内皮细胞。
