The impact of PM2.5 on the human respiratory system.

Recently, many researchers paid more attentions to the association between air pollution and respiratory system disease. In the past few years, levels of smog have increased throughout China resulting in the deterioration of air quality, raising worldwide concerns. PM2.

[Effect of soluble PD-L1 released by lung cancer cells in regulating the function of T lymphocytes].

Objective: To explore the expression of soluble programmed death ligand-1 on lung cancer cells and to clarify its biological function through PD-1/PD-L1 pathway in regulating the function of T lymphocytes.

Methods: Labeled monoclonal antibody and flow cytometry were used to analyze the expression of PD-L1 and its receptor PD-l on lung cancer cells and human T lymphocytes, respectively. The level of sPD-L1 in the supernatant of lung cancer cells was determined with an ELISA kit.

[The level of soluble programmed death-1 in peripheral blood of patients with lung cancer and its clinical implications].

Objective: To analyze the expression of soluble programmed death-1 ligand 1 (sPD-L1) in the serum of patients with lung cancer and to explore its biological and clinical implications.

Methods: Fifty-five male and twenty-six female lung cancer patients ages 34 to 87 years (mean age 65 ± 6) were selected from the Department of Respiratory Diseases in The Second Affiliated Hospital of Soochow University from June 2009 to March 2011. All lung cancer patients were newly-diagnosed, treatment-free and confirmed by histopathology or cytopathology.
