RESUMO
Objective To evaluate the efficacy and safety of reamed interlocking intramedullary nail in the treatment of upper tibial fracture .Methods According to the random number table ,81 patients with tibial fracture were divided into observation group ( reaming intramedullary interlocking nails ) of 41 cases and control group (unreamed intramedullary nails) of 40 cases.The operation time,healing time,fracture of nail lock,fracture union and infection were observed and compared between the two groups .Results The operation time of the observation group [(55.3 ±19.2)min] was significantly longer than that of the control group [(44.7 ±12.4)min].The healing time of the observation group [(16.2 ±4.2) weeks] was significantly shorter than that of the control group [(24.1 ± 5.2)weeks],the differences were statistically significant (t=6.543,8.235,all P<0.05).The fracture of the nail, fracture healing were compared between the two groups,the differences were not statistically significant(χ2=0.086,0.753, 0.633,0.598,all P>0.05).Conclusion Reamed interlocking intramedullary nail in the treatment of upper tibial fracture has reliable curative effect .The internal fixation is more stable and the healing rate of the patients is faster .
RESUMO
Objective To assess the correlation between coronary heart disease and common carotid artery and femoral artery atherosclerosis with two-dimensional color Doppler ultrasound (2D-CDUS). Methods Ninety patients with coronary heart disease were divided into three subgroups according to the extent of coronary artery stenosis observed with coronary angiography, and 50 normal subjects were taken as normal group. Ultrasound examination with high-frequency linear array probe was performed to measure IMT of common carotid and femoral artery in order to observe the plaque and extent of stenosis, the formation of blood dynamics, physical characteristics and hemodynamic environmental parameters. Results Among the coronary disease groups, common carotid artery and the femoral artery IMT, atherosclerotic plaque in the number, rate and all points increased along with the degree of coronary artery stenosis increasing. Physical characteristics and its hemodynamic environmental parameters had some changes with the increase of atherosclerosis. Conclusion The atherosclerosis of common carotid artery and the femoral artery are closely related with coronary atherosclerosis.
