Objective To analyse the clinical effect and mechanism of hirudin in the treatment of patients with lower limb venous thrombosis after fracture.Methods 56 patients who were diagnosed with lower limb venous thrombosis after fracture in our hospital were collected.All patients were randomly divided into experimental group (n:28) and control group (n:28).12h after fracture operation, patients in control group were treated with subcutaneous injection of low molecular weight heparin calcium, patients in experimental group were treated with Maixuekang capsule ( hirudin) orally on the basis of control group.Before and after the treatment, the plasma levels of thrombin antithrombin complex ( TAT) , thrombin activated fiber soluble inhibitor (TAFI), D-Dimer (D-D), fibrinogen (FIB), thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT) and clinical effect were detected in all patients.Results After treatment, the total effective rate of experimental group ( 92.86%) was significantly higher than that of the control group ( 71.43%) ( P<0.05 );compared with control group, the plasma levels of TAT, TAFI were lower in the experimental group (P<0.05); the plasma levels of D-D, FIB were lower in the experimental group (P<0.05); the plasma levels of TT,PT,APTT were higher in the experimental group ( P<0.05 ) .Conclusion The hirudin could inhibit thrombin activation and coagulation function in fracture patients with lower limb venous thrombosis, decrease the plasma D-D and FIB levels for improving blood hypercoagulable state and preventing thrombosis,thus improve the clinical efficacy.

Objective To explore and analyze effect of heparin combined with urokinase therapy on lower limb venous thrombosis.Methods 90 cases with lower extremity venous thrombosis were chosed and divided into control group of 45 cases and experimental group of 45 cases according with random number table method.Control group was given pure low molecular heparin treatment, experimental group was treated with small dose of urokinase static drop on the basis of control group, 7 days for a course, a total of 2 course of treatment.Compared two groups before and after treatment of lower limb venous patency rate changes, blood coagulation function index, adverse reactions and the recurrence rate.Results Compared with control group post-treatment.patency rate of posterior divisions, popliteal vein and posterior tibial vein of experimental group were significantly better (P<0.05).Experimental group post-treatment compared with control group post-treatment, PT, APTT, TT time had significant difference ( P <0.05 ).Patients incidence of adverse reactions were significantly lower than control group ( P <0.05 ).Patients were followed up for 1 year recurrence rate was significantly lower than control group ( P <0.05 ).Conclusion Effect of low molecular heparin combined with urokinase in the treatment of venous thrombosis of lower limbs significant and its prognosis is well.

Objective Retrospective study of color Doppler ultrasound image of the characteristics of lower limb venous thrombosis,evaluate the clinical diagnostic value,and to study the comformation for the purpose of clinical early diagnose and treatment.Methods Color Doppler ultrasound diagnoses were carried out on 32 patients with lower extremity venous thrombosis and the thrombus echo characteristics,scope of thrombus,venous wall,vascular diameter and blood flow were observed.Results In 32 cases,17 cases were diagnosed by color Doppler ultrasound of acute lower limb venous thrombosis,12 cases of subacute thrombosis,and 3 cases of chronic thrombosis.The ultrasonic imaging characteristics of every period has its specificity.Also,majority of the patients had traumatic fractures.Conclusion Color Doppler ultrasound is the top noninvasive method for venous thrombosis of lower limb,it can not only confirm the range and degree of lower extremity venous thrombosis,and to dynamically observe its ongoing at the same time.It has irreplaceable advantage over other imaging diagnose method in clinical diagnosis of lower limb venous thrombosis.
