[Relationship of Serum D-dimer, Fibrinogen, C Reactive Protein and Interleukin 6 with Thrombus Dissolution Volume in Acute Iliac Femoral Vein Thrombosis Model Rats].

OBJECTIVE

To explore the relationship among the serum D- two polymer, fibrinogen, C reactive protein and interleukin 6 and thrombus dissolution volume in acute iliac femoral venous thrombosis model rats.

METHODS

A total of 60 rats were randomly divided into 3 groups: deep venous thrombosis group (DVT group), sham operation group and normal control group. In DVT group the single side of the iliofemoral vein incomplete with micro vessel was cliped under chloral hydrate anesthesia; in sham operation group the single side of the iliofemoral vein should be explored without using micro vessel clip under chloral hydrate anesthesia; the and normal control group only experienced chloral hydrate anesthesia. A positive correlation was showed between the 2 time points of D-dimer and the corresponding thrombolytic volume, and the Pearson coefficient was 0.307, and R was 0.412 (P<0.05).

RESULTS

The D-dimer, fibrinogen, C reactive protein and interleukin-6 levels before and after treatment of 60 rats were shown to be significantly different (P<0.05) between DVT group, sham operation group and normal control group. The D-dimer and fibrinogen level was first rised and then decreased in DVT group, sham operation group. There was a positive correlation between C reactive protein/interleukin-6 and the level of D-dimer /fibrinogen from T1 to T3 time point (P<0.05). There was a negative correlation between C reactive protein/interleukin-6 and the level of D-dimer /fibrinogen from T4 to T6 time point (P<0.05).

CONCLUSION

The changes of serum D-dimer, fibrinogen, C reactive protein and interleukin 6 in the acute iliac femoral vein thrombosis model firstly increase and then decrease. These changes can reflect the process of blood coagulation and fibrin dissolution in the course of venous thrombosis of iliac vein.
