The hemostatic effect of hemocoagulase in lung cancer radical surgery analysis and its effect on PAR-1 / 中国生化药物杂志

ABSTRACT

Objective To investigate hemocoagulase hemostatic effect in lung cancer radical surgery and its effect on protease-activated receptor-1 (PAR-1 ).Methods 86 cases of pathologically confirmed lung cancer patients were randomly divided into control group and observation group,which controls were used etamsylate,observation group were used hemocoagulase,then to measure the amount of bleeding,clotting system-related factors before and after surgery,using ELISA assay to detect P-selectin,flow cytometry to measure platelet PAR-1 ,Western Blot to determine lung tissue expression of PAR-1,and the resulting data were statistically analyzed. Results The blood loss of observation group during surgery and postoperative 2d compared with the control group,had a significant difference (P<0.05 );flow cytometry results showed that,PAR-1-positive rate and P-selectin in different time periods in observation group were no statistically significant,while had a statistically significant compared with control group(P<0.05 );Western Blot detected hemocoagulase of lung tissue in patients with PAR-1 had no obvious effect,while control group had significant difference (P<0.05).Conclusion Venin hemocoagulase in lung cancer radical surgery can reduce the amount of bleeding,and be more stable for the role of the coagulation system,as well as less effect on the P-selectin and PAR-1.The results suggest that vonin hemocoagulase might not make patients with systemic hypercoagulable state in patients undergoing radical process with lung cancer,in other words it might not lead to PAR-1 highly expression to cause tumor cell metastasis.
