Research Advances in Molecular Mechanisms of the Invasion and Metastasis of Lung Cancer / 中国医学科学院学报

The basic way of invasion and metastasis of lung cancer is that the tumor cells shed in the extracellular matrix, invade the basement membrane and the surrounding tissue, infiltrate into blood flow, and then survive and transport via the blood flow. After having been extravasated, migrated and arrested in the distant site, they finally form a metastatic lesion. Some basic mechanisms are required in these steps, such as tumor stem cells, diffusion and activity of tumor cells, escaping from apoptosis, angiogenesis and lymphangiogenesis, infiltration into blood flow, circulation and exudation, and distant metastasis proliferation. A better understanding of the mechanisms of the invasion and metastasis of lung cancer will facilitate the prevention and treatment of lung cancer.

New Advances in the Diagnosis and Treatment of Allergic Bronchopulmonary Aspergillosis / 中国医学科学院学报

Allergic bronchopulmonary aspergillosis is one of major pulmonary fungal diseases. Although it is not a rare in clinical settings,the misdiagnosis rate is high and the treatment effectiveness remains unstable. This article reviews the recent advances in the diagnosis and treatment of this disease.
