Primary objective: functional imaging and quantitative imaging detection of the effects of Endostar combined with chemotherapy and radiotherapy on Non-small Cell Lung Cancer (NSCLC).

Secondary objective: To evaluate 1) the role of Endostar in regulating tumor vessels and normalizing of microenvironment; 2) Toxicity of Endostar combined with chemotherapy.
