Brief Summary:
Most researches revealed that volatile anesthetic sevoflurane has a more marked cardioprotective effect against ischemia compared with intravenous agent propofol.However, propofol has been suggested to be more benefit for attenuation of surgery-induced immunosuppression.Thus, the aim of this study was to investigate under the specific OPCAB surgical stress, the influence of 3 established anesthetic techniques: sevoflurane, propofol and combine of sevoflurane and propofol maintained anesthesia on the apoptosis of circulating lymphocytes.

Arm Intervention/treatment
Experimental: Sevoflurane Drug: Sevoflurane
anesthesia was maintained with sevoflurane (end-tidal concentration 1.0-1.5 minimum alveolar concentration)

Experimental: Propofol Drug: Propofol
anesthesia was maintained with propofol (2-4 μg/ml via target-controlled infusion)

Experimental: Combine of sevoflurane and propofol Drug: combine of sevoflurane and propofol
anesthesia was maintained with a combine of propofol (1 μg/ml via target-controlled infusion) and sevoflurane (end-tidal concentration 0.7-1.0 minimum alveolar concentration)

Primary Outcome Measures :
  1. Lymphocyte Count [ Time Frame: 1 day after surgery ]
    Blood samples were obtained 24 h after the surgery for routine blood examination. This analysis was performed in the hospital laboratory using routine laboratory procedures.

Secondary Outcome Measures :
  1. Intensive Care Unit Staying Days [ Time Frame: participants will stay in intensive care unit after surgery, an expected average of 2 days ]
