OBJECTIVETo evaluate the levels of coagulation indicators [thrombomodulin(TM)/ thrombin-antithrombin complexes(TAT)/ α-plasmin inhibitor-plasmin complexes(PIC)/ tissue plasminogen activator-inhibitor complexes(t-PAIC) /D-Dimer(D-D)/fibrin degradation products(FDP)] in the critical patients with thromboembolism, analyse their correlation with inflammatory factor (procalcitonin/C reactive protein/ interleukin-6), and explore the diagnostic significance of coagulation indicators for these patients.

METHODSThe serum levels of the coagulation indicators (TM/TAT/PIC/t-PAIC/D-D /FDP) and inflammatory factors (PCT/IL-6/CRP) were detected in the patient group with critical thromboembolism (n= 38) and critical patient group without thromboembolism as control (n= 81) . The correlation of coagulation indicators with inflammatory factors was analyzed.

RESULTSThe values of TM/TAT/PIC/D-D/FDP in thromboembolism group were statistically significantly higher than those in control group (P<0.05). However, the t-PAIC values were not significantly different (P>0.05), and 3 inflammatory factors (PCT/CRP/IL-6) in thromboembolism patients were significantly higher than those in control group (P<0.05). The correlation analysis suggested that the correlation coefficients of TM with PCT, CRP and IL-6 were 0.288, 0.249 and 0.270, respectively (P<0.05).

CONCLUSIONThe critical patients with thromboembolism show an obviously higher systemic inflammatory response, and accompany with coagulation dysfunction. There is a network relationship between inflammation and coagulation, the interaction of inflammatory factors with coagulation indicators promotes thromboembolism and inflammation.
