目的:探讨铜绿假单胞菌外毒素(PEA)在铜绿假单胞菌肺部感染及定植表达差异的临床价值。方法 SD 大鼠180只,随机分为 PA(铜绿假单胞菌)感染模型组,PA 咽部定植组及生理盐水对照组。观察 PA 感染与定植中血液 PEA 变化。结果肺组织结构正常,定植组与对照组无明显区别,模型组出现了明显肺泡及肺间质水肿、出血、炎性细胞聚集的炎症表现。模型组血液 PEA DNA 表达在接种后第3、7、11天均明显高于定植组,二者比较存在统计学意义(P 均<0.01)。结论血清检测有助于对铜绿假单胞菌感染与定植的鉴别诊断,且可预测肺部炎症的程度及预后。
目的:探討銅綠假單胞菌外毒素(PEA)在銅綠假單胞菌肺部感染及定植錶達差異的臨床價值。方法 SD 大鼠180隻,隨機分為 PA(銅綠假單胞菌)感染模型組,PA 嚥部定植組及生理鹽水對照組。觀察 PA 感染與定植中血液 PEA 變化。結果肺組織結構正常,定植組與對照組無明顯區彆,模型組齣現瞭明顯肺泡及肺間質水腫、齣血、炎性細胞聚集的炎癥錶現。模型組血液 PEA DNA 錶達在接種後第3、7、11天均明顯高于定植組,二者比較存在統計學意義(P 均<0.01)。結論血清檢測有助于對銅綠假單胞菌感染與定植的鑒彆診斷,且可預測肺部炎癥的程度及預後。

Objective To investigate the pseudomonas aeruginosa exotoxin (PEA) in pseudomonas aeruginosa lung infection, and the clinical value of engraftment expression differences. Methods 180 SD rats, were randomly divided into PA(pseudomonas aeruginosa) infection model group, PA pharyngeal engraftment group and normal saline control group. Observation of PA infection and engraftment of PEA changes of blood. Results The structure of normal lung tissue, engraftment group and the control group, no significant difference between model group and there is an obvious alveolar pulmonary interstitial edema, hemorrhage and inflammatory cell aggregation of inflammation. Model group blood PEA DNA expression in 3, 7, 11 days after inoculation were significantly higher than that of engraftment group, which shows there is statistical significance(P<0.01). Conclusion Serum helps to pseudomonas aeruginosa infection and engraftment, the differential diagnosis of the degree and the prognosis of lung inflammation and predictable.
