  Purpose
Serum proteomics is a very useful tool to identify various disease. The purpose of the present study was to find differential proteins among patient with normal, SIRS, sepsis, severe sepsis, death and to screen potential biomarkers for their dynamic changes. Serum proteins were identified by iTRAQ labeling and LC-MS/MS. The bioinformatics analysis was performed with the Mascot software and the International Protein Index (IPI) and the Gene Ontology (GO) Database and KEGG pathway Database. The differentially expressed proteins were verified by Western blot by another sample collected from clinical.

Primary Outcome Measures:
  • Survival status [ Time Frame: 28 days after admission to ICU ]
    The survival time of patients more than 28days is defined as survival. The survival time of patients less than 28days is defined as death.


Estimated Enrollment: 100
Study Start Date: May 2010
Estimated Study Completion Date: March 2012
Estimated Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
Normal
normal person under physical examination
SIRS
  1. temperature >38 ℃ or <36℃;
  2. pulse rate>90 beats/min;
  3. ventilatory rate>20 breaths/min or hyperventilation with partial pressure of arterial carbon dioxide (PaCO2)<32mmHg;

sepsis is defined as SIRS plus confirmed infection.
severe sepsis
  1. severe sepsis: sepsis associated with organ dysfunction, hypoperfusion, or hypotension;
  2. septic shock: sepsis with arterial hypotension, despite adequate fluid resuscitation.
death
sepsis patients within 48 hours before death
