Biospecimen Retention:   Samples Without DNA
peripheral venous blood from septic patients and healthy controls, anticoagulate with EDTA-K2

Enrollment: 39
Study Start Date: December 2008
Study Completion Date: April 2010
Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
Detailed Description:

First, we will detect PD-L1 expression on PBMC of septic patients and healthy controls.

Second, blockade of PD-1/PD-L1 pathway in vitro and stimulate with some biomolecules and then analyze the PBMC function and apoptosis by flow cytometry.

Then, compare with healthy controls and find the differences.
