Brief Summary:
The patients with sepsis are in the state of hypermetabolism, increased resting energy expenditure, protein and fat catabolism disorder, negative nitrogen balance, insulin resistance, hyperglycemia, and amino acid metabolism disorders. However, it is remain unclear the changes of amino acids expression profiling in sepsis patients. In this study, the investigators has planned to enroll 100 subjects, including 20 cases with systemic inflammatory response syndrome (SIRS), 20 cases with sepsis, 20 cases with severe sepsis and 20 with septic shock. In addition, this study also include 20 normal cases as control. The serum sample of patients with sepsis is draw on days 1, 3, 5, 7, 10, and 14 after first ICU admission. High-performance liquid chromatography and tandem mass spectrometry was used to detect the quantification of amino acids. The amino acids expression profiling contain Arginine, Ornithine, Histidine, Cystine, Isoleucine, Cystathionine, Leucine, Homocystine, Lysine, α-Amino-n-Butyric Acid, Methionine, Alanine, Phenylalanine, Anserine, Threonine, β-Alanine, Tryptophan, β-Amino-Isobutyric Acid, Valine, Carnosine, γ-Amino-n-Butyric Acid, Ethanolamine, Glycine, δ-Hydroxylysine, Serine, Hydroxy-L-Proline, Taurine, 1-Methyl-L-Histidine, Tyrosine, 3-Methyl-L-Mistidine, α-Amino-Adipic, Phospho-Ethanolamine, Asparagine, Phospho-L-Serine, Aspartic acid, Proline, Citrulline, Sarcosine, Glutamic acid, Argininosuccinic Acid, Glutamine, Homocitrulline. The investigators speculate that measurement of amino acids expression profiling could be taken as an indicator for assessment in critically ill patients.

SIRS group
(1) temperature > 38oC or < 36oC; (2) pulse rate > 90 beats/min; (3) ventilation rate > 20 breaths/min or hyperventilation with a partial pressure of arterial carbon dioxide (PaCO2) < 32 mmHg; (4) white blood cell (WBC) count >1 2,000μL-1 or < 4000 μL-1 , or > 10% immature cells.
normal control
For the healthy control outpatients, possibilities of acute or past chronic diseases were excluded. Moreover, we made sure that the healthy control subjects had not been hospitalized or taken vitamin-based substitutive drugs in the last 12 months, and proved normal in physical checkups and lab examinations.

Primary Outcome Measures :
  1. Patients Outcome [ Time Frame: 28 days ]
    The survival time of patients more than 28 days is defined as survival. The survival time of patients less than 28 days is defined as death.
