OBJECTIVE: To explore the protective effect and mechanism of ligustrazine (LGT) and propofol (PRO) on peri-operational liver ischemia-reperfusion injury (HIRI). METHODS:Thirty-six patients scheduled for hepatic surgery were randomly divided into the control group, the LGT group, the PRO group and the LGT + PRO group, 9 patients in each group. Changes of superoxide dismutase (SOD), lipid peroxide (LPO), ratio of thromboxane B2 (TXB2) and 6-keto-prostaglandin F1alpha (6-keto-PGF1alpha), alanine aminotransferase (ALT) activity, and the ultrastructure of liver tissue were dynamically observed. RESULTS: Compared with the control group, SOD activity was significantly higher, LPO concentration, TXB2/6-keto-PGF1alpha ratio and ALT value were significantly lower (P < 0.05 and P < 0.01) in the LGT group, the PRO group and the LGT + PRO group during HIRI, with the abnormal changes of hepatic ultrastructure 25 min after reperfusion significantly alleviated in the three treated group. CONCLUSION: Combination of ligustrazine and propofol shows protective effect on liver by decreasing oxygen free radical level, reducing lipid peroxidation and adjusting TXA2/PGI2 imbalance after hepatic ischemia-reperfusion in patients undergoing hepatic cancer surgery.
