The serum levels of Ang-1 and Ang-2 in septic patients with non-bloody effusions and bloody effusions. We used ELLISA method to test the Ang-1 and Ang-2 in serum. The results showed a) There was no significant difference in Ang-1 between the two groups; b) The level of Ang2 was remarkably increased in bloody effusion group, when compared with the non-bloody effusion group (30,527 pg/mL vs. 21,536 pg/mL; Padj = 0.018). Padj value was calculated using logistic regression adjusted for APACHE II and SOFA scores. *P < 0.05
