Contrast enhancement was substantially een across all three areas of interest, Wilke said. Anoa analysis of the 11 studies showed no significant difference (p = 0.014) in the aerage Hounsfield unit alue of the main pulmonary artery (380 HU), left pulmonary artery (382 HU), right pulmonary artery (381 HU), distal pulmonary arteries (354 HU), proximal left main artery (410 HU), and the proximal right coronary artery (382 HU).

造影增强大体上正好可以到达三个需要注意的部位，Wilke说。11项研究的方差分析(p = 0.014)显示肺动脉主干（380 HU）的平均Hounsfield单位值没有明显不同。

The study included 30 normal subjects, 40 central pulmonary carcinoma with signs of central pulmonary artery infiltration, 5 pulmonary artery aplasia, 4 pulmonary arteriovenous malformation, 3 af...

其中正常 30例，中央型肺癌累及中央肺动脉 40例，肺动脉发育不良 5例，肺动静脉畸形 4例，肺动脉袖状切除成形术后 3例。

The slow progress of researches on pulmonary stem cells up to date has its root in the complex structure of pulmonary tissues and respiratory tracts, which is demonstrated by the facts that the respiratory system is composed of at least 40 types of cells, plus that the growth, renewal, and regeneration rate or capacity of respiratory epithelium are extremely limited. Mean while, there have been no specific stem cell markers for pulmonary and lung cancer, so researchers rely on stem cell markers borrowed from other systems to search for stem cells in pulmonary system.

目前对于肺干细胞的研究进展缓慢，究其原因主要是肺组织和气道具有复杂的内在结构，呼吸系统至少包含40种不同类型的细胞，呼吸上皮本身只有极低的生长更新率和非常有限的再生能力，同时肺干细胞的表面标志物也缺乏特异性，只能借助其他组织已知的干细胞标记物进行对比观察。

The experimental group has various changes in the different density of potentill anserine extract. The small rat pulmonary tissue surface ofⅠgroup can see sporadic petechia of different degree; pulmonary alveolus cavity can see sporadic erythrocyte under the microscope. The small rat pulmonary tissue surface of Ⅱ group is no obvious abnormality by naked eye; pulmonary alveolus cavity can see sporadic erythrocyte and thin powder color liquid under the microscope. Two groups all have the capillary vessel of alveolar wall dilation and the endothelial cell hyperplasia and hypertrophy in different degree.

实验组不同浓度的蕨麻提取物对小鼠肺组织的影响不同，Ⅰ组小鼠肺组织表面肉眼见不同程度的散在点状出血、显微镜下肺泡腔内见散在红细胞；Ⅱ组小鼠肺组织表面肉眼无明显异常，显微镜下肺泡腔内见散在红细胞及淡伊红色液体，两组均见肺泡壁毛细血管扩张充血及毛细血管内皮细胞呈不同程度的增生肥。

In patients with congenital heart defects associated with pulmonary hypertension, NO and NOS play a role in pathological process of pulmonary arteriopathy, and the NOS mRNA expression level was proportional to the severity of pulmonary hypertension or pulmonary arteriopathy.

NOS， NO 参与先天性心脏病合并肺动脉高压肺血管病变的病理过程；肺组织NOS mRNA的表达，随肺动脉高压和肺血管病变程度的加重而下降。

Results:Compared with the simple pulmonary tuberculosis patients,the patients with infiltrative pulmonary tuberculosis complicated with diabetes were more serious,more caseous foci,more pulmonary cava,more bacilli in sputum and more recurrent cases.The therapeutic effect of the patients with infiltrative pulmonary tuberculosis complicated with diabetes was similar to those with simple pulmonary tuberculosis in the sputum bacillus disappearance rate and the tuberculosis focus absorption,if the diabetes was stable and the blood glucose was less than 8.4 mmol/L.

结果：浸润型肺结核并发糖尿病的患者比单纯肺结核病情较重、干酪病灶多、空洞多、排菌和复治病例比例大的临床特点；在糖尿病稳定，血糖控制在8.4 mmol/L以下，其痰菌阴转率、病灶显吸率与单纯性肺结核的疗效相似。

In this group,16 cases were involved in central pulmonary arteries (66.7%) and 4 cases with dilated bronchial arteries (17%),9 cases with pulmonary infraction (37.5%) whose pulmonary embolismic index was ranged from 24% to 83%, other 15 cases with no pulmonary infraction whose embolismic index was ranged from 5% to 61%,and there were significant difference between the two groups.

中央肺动脉受累16例，占66.7％（16/24），支气管动脉扩张4例，占16.7％（4/24），发生肺梗死9例，占37.5％（9/24）。9例发生肺梗死的肺动脉栓塞指数24％～83％（平均46.5％），15例非肺梗死的肺动脉栓塞指数5％～61％（平均21％），两组栓塞指数具有显著差异性。

Abstract］ Objective To evaluate the value of spiral CT dynamic contrast-enhancement scanning on pulmonary embolism by analysing the CT appearance of pulmonary embolism restrospectively.Methods Collect and analyze the appearance in multi-slice spiral CT of 24 patients with pulmonary embolism,especially the embolismic index,the involved proportion of central pulmonary arteries,the presenting proportion of bronchodilation and pulmonary infarction.

目的 回顾性分析肺动脉栓塞的CT表现，探讨层螺旋CT动态增强扫描对肺动脉栓塞的诊断价值方法搜集经多层螺旋CT动态增强扫描确诊的肺动脉栓塞24例，回顾性分析其CT表现，重点分析肺动脉栓塞指、中央肺动脉受累比例、有无支气管扩张显示、是否合并肺梗死。
