Objective:To analyze the correlations of plasma levels of endothelin-1(ET-1)and calcitonin gene-related pepfide(CGRP) with ascites and liver function in cirrhosis patients with portal hypertension. Methods:Seventy eight cirrhosis patients with portal hy-pertension were enrolled in this study and the plasma levels of ET-1 and CGRP in the peripheral venous blood and portal venous blood of all patients were detected. Among the 78 patients,42 with ascites and 36 without ascites. Based on child-pugh classification,35 cases were in class A,26 cases were in class B and 17 cases were in class C. Results:There were significant differences in ve-nous blood ET-1 levels between portal hypertension patients without ascites and the control patients(P<0.05). Significant differences in venous blood ET-1 levels between patients with ascites and patients without ascites were observed(P<0.05). In patients with ascites,there were significant differences in ET-1 levels between portal vein blood and peripheral venous blood(P<0.05). Significant differ-ences in venous blood levels of CGRP between patients with ascites and patients without ascites were observed(P<0.05). There were statistical differences in levels of ET-1 and CGRP in the peripheral venous blood and portal venous blood between class A patients and class B patients(P<0.05). There were statistical differences between levels of EF-1 in portal venous blood and levels of ET-1 in peripheral venous blood in class C patients(P<0.05). There were statistical differences between levels of CGRP in peripheral ve-nous blood and levels of CGRP in portal venous blood in class C patients(P<0.05). Furthermore,the liver function was negatively cor-related with level of ET-1 and CGRP in the peripheral venous blood and portal venous blood(rs=-0.783,P<0.05;rs=-0.695,P<0.05)(rs=-0.642,P<0.05,rs=-0.671,P<0.05). Conclusions:The high level of venous blood ET-1 and CGRP is correlated with as-cites formation in cirrhosis patients with portal hypertension. Moreover,the liver function is also correlated with venous blood levels of ET-1 and CGRP,which indicates that venous blood levels of ET-1 and CGRP might be potent hypertensive indica-tors of liver function in cirrhosis patients.
