恶性胸腔积液的治疗
Introduction Malignant pleural effusions ( MPEs) are defined as an abnormal amount of pleural fluid accumulation in the pleural space and are the result of an imbalance between excessive pleural fluid formation and slower pleural fluid absorption.They are caused by a variety of mechanisms including tumor obstruction of lymphatic flow, spread of malignant cells via the systemic circulation, and tumor invasion of the pulmonary arterioles[1] .

The Molecular Mechanisms of Nm23-H1 Gene Transfection on Reversing Invasion and Metastasis Phenotype in Human High-metastataic Large Cell Lung Cancer Cell Line L9981
Background: Our previous studies have proved that nm23-Hl gene was a tumor metastatic suppressive gene, tumor metastasis phenotype of human lung cancer could be reversed by transfection of nm23-H1 cDNA, but the molecular mechanism of nm23-H1 for inhibiting tumor invasion and metas-tasis is unclear. The aim of this study is to explore the molecular mechanism of nm23-Hl reversing the invasion and metastasis phenotype in human high-metastatic large cell lung cancer line L9981.
