Correlation of visfatin and L-PGDS with lower extremity arteriosclerosis
Objective To investigate the relationship between lipocalintype prostaglandin dsynthase(L-PGDS) and visfatin in the lower extremity atherosclerotic plaque. Methods Collected from February 2014 to February 2016 in vascular surgery of our hospital 40 cases of femoral artery atherosclerotic plaque intima specimens (observation group), 20 cases of splenic artery, superior mesenteric artery samples (control group), the expression of visfatin and L-PGDS protein were detected by immunohistochemical staining, and the expression of visfatin and L-PGDS mRNA were determined by RT-PCR. Results The observation group visfatin protein expression was (121.42±11.07), significantly higher than the control group (72.07±12.81), and L-PGDS protein expression was (87.93±9.73), significantly lower than the control group (107.04±10.58), the difference was statistically significant (P<0.05). The relative expression of visfatin mRNA in the observation group was (0.321±0.024), which was significant higher than that of the control group (0.217±0.031), while L-PGDS mRNA was (0.203±0.018), significantly lower than the control group (0.314±0.029), the difference was statistically significant (P<0.05); The expression of L-PGDS protein was negatively correlated with the expression of visfatin protein in the plaque tissue (r=-0.617, P<0.05), visfatin mRNA and L-PGDS mRNA were negatively correlated (r=-0.645, P< 0.05). Conclusion Visfatin and L-PGDS in lower extremity atherosclerosis occurrence and development have an important relationship, both of them may play an antagonistic role.
