Effect and Mechanism of Dialectical Treatment of Modified Yiqi Huoxue Tongmai Decoction on Recanalization Post-thrombotic Syndrome of Lower Limbs
Objective:To discuss the clinical efficacy of dialectical treatment of modified Yiqi Huoxue Tongmai decoction for recanalization post-thrombotic syndrome of lower limbs (PTS) and investigate its effects on levels of Qi deficiency and blood stasis syndrome. And platelet endothelial cell adhesion factor-1 (PECAM-1)
vascular cell adhesion molecule-1 (VCAM-1)
matrix metalloproteinase-2 (MMP-2)
MMP-9
interleukin-4 (IL-4)
IL-6
P-selectin
and tumor necrosis factor-α (TNF-α). Method:One hundred and ten patients were randomly divided into control group (55 cases) and observation group (55 cases) by random number table. Both groups' patients got heparin for anticoagulation and urokinase for thrombolysis. Patients in contral group additionally got diosmin tablets
0.9 g/time
2 times/day
while patients in observation group additionally used modified Yiqi Huoxue Tongmai decoction
1 dose/day. The treatment course was 16 weeks in both groups. Score of Villalta was graded
and vascular recanalization was evaluated by color doppler ultrasound. The changes in circumference of lower limb were detected in both groups
and the levels of Fibrinogen (FIB)
D-dimer (D-D)
PECAM-1
VCAM-1
MMP-2
MMP-9
IL-4
IL-6
P-selectin and TNF-α were detected before and after treatment. Result:The total effective rate was 90.91% in observation group
higher than 76.36% in control group(χ2=4.251
P<0.05). Rate of vascular recanalization was 89.1% in observation group
higher than 69.1% in control group (χ2=6.075
P<0.05). At week 12 and week 16 after treatment
scores of Villalta in observation group were lower than those in control group (P<0.01)
and the changes in top-knee circumference and bottom-knee circumference were all lower than those in control group (P<0.01). Levels of FIB
D-D
P-selectin
PECAM-1
VCAM-1
MMP-2
MMP-9
IL-6 and TNF-α in serum of observation group were all lower than those in control group (P<0.01)
while IL-4 level was higher than that in control group (P<0.01). Conclusion:Dialectical treatment of modified Yiqi Huoxue Tongmai decoction in patients with PTS can relieve symptoms and signs of patients
improve rate of vascular recanalization
and regulate inflammatory factors and cell adhesion molecules for ameliorating thrombus.
