胸水LDH同工酶、VEGF及IL在良恶性病变中的临床诊断价值

Clinical Diagnostic Value of Pleural Effusion, LDH Isoenzyme, VEGF and IL in Benign and Malignant Lesions

摘要: 胸膜腔是位于肺和胸壁之间的一个潜在的腔隙。在正常情况下脏层胸膜和壁层胸膜表面上有一层很薄的液体，在呼吸运动时起润滑作用。胸膜腔和其中的液体并非处于静止状态，在每一次呼吸周期中胸膜腔形状和压力均有很大变化，使胸腔内液体持续滤出和吸收并处于动态平衡。任何因素使胸膜腔内液体形成过快或吸收过缓，即产生胸腔积液(pleural effusions, PE)，简称胸水。

Abstract: The pleural space is a potential space located between the lungs and the chest wall. Under normal circumstances, there is a thin layer of fluid on the surface of the visceral pleura and parietal pleura, which lubricates during breathing exercise. The pleural space and the fluid in it are not at rest, and the shape and pressure of the pleural cavity vary greatly from breath cycle to breath, allowing fluid to be continuously filtered and absorbed in the pleural cavity and in dynamic equilibrium. Anything that causes fluid in the pleural space to form too quickly or absorb too slowly produces pleural effusions (PE), referred to as pleural effusions.
