Arm Intervention/treatment
Experimental: Procalcitonin-guided antibiotic treatment group

Patients were divided into 2 subgroups:

  1. No infection group (including patients with procalcitonin<0.1 ng/ml at enrollment, and patients with 0.1 ng/ml ≤procalcitonin ≤0.25 ng/ml at enrollment who are with stable respiratory and hemodynamics, and without serious complications) : the group is not given the application of antibiotics.
  2. Infection group (including patients with procalcitonin>0.25 ng/ml at the time of enrollment, and patients with 0.1 ng/ml ≤ procalcitonin≤0.25 ng/ml at enrollment who have severe disease, unstable hemodynamics, and severe complications or intensive care unit treatment): the group is given the application of antibiotics. According to the guidelines for severe sepsis / septic shock treatment, the standard for discontinuation of antimicrobial agents: If the procalcitonin level falls below <0.1 ng/ml or more than 80%, compared with the baseline before enrollment, it is recommended to discontinue the antimicrobial agent.
Other: Procalcitonin
The application of antimicrobial agents is determined by PCT results.

Active Comparator: Standard antibiotic therapy group
The application of antibiotics is given to patiens according to the doctor's experience.
Other: Clinical Experience
The application of antimicrobial agents is determined by clinical experience of doctors.

Primary Outcome Measures :
  1. Antimicrobial prescription rate [ Time Frame: 14 days ]
  2. Number of days of antimicrobial application [ Time Frame: 14 days ]
  3. The number of days in hospital [ Time Frame: 14 days ]

Secondary Outcome Measures :
  1. Effective rate of clinical treatment [ Time Frame: 14 days ]
  2. Quality of life score [ Time Frame: 6 months ]
  3. Adverse reaction rate [ Time Frame: 14 days ]
  4. Bacterial resistance rate [ Time Frame: 14 days ]
  5. The incidence of complications [ Time Frame: 14 days ]
  6. fungal infection rate [ Time Frame: 14 days ]
  7. mortality rate [ Time Frame: 14 days ]
  8. The proportion of patients with at least once acute exacerbation in 6 months [ Time Frame: 6 months ]
