(2)The experimental group's scores of medical records analysis, the assessment scores of clinical skills and the student questionnaire score were higher than those of the control group and the two groups' score difference was statistically significant. Conclusion To strengthen the training of medical ultrasound medical imaging direction students' logical thinking ability can significantly improve the quality of teaching, and it is worthy to be promoted and applied.

Objective To observe the influence of low or middle power microwave radiation on tissues adja-cent to titanium alloy implants. Methods Titanium alloy internal fixation plates were implanted into the upper femur of the right side of New Zealand white rabbits, the left femurs served as the control. Then the femurs were exposed to 20, 40, 60, or 80 W of microwave radiation at a frequency of 2450 MHz for 30 minutes, and real-time temperature of the implants and its adjacent muscles were recorded. The nerve conduction study of the sciatic nerve was performed by stimulating the nerve and recording from gastrocnemius in both groups. Finally, all the rabbits were sacrificed and histo-logical studies were performed on nerve and muscle sections. Results Compared to the control limbs, temperatures of limbs with titanium alloy implants increased significantly when exposed to microwave radiation at 60 and 80 W ( P<0.05) but no significant differences were revealed when exposed to radiation at 20 and 40 W ( P<0.05) . For the sciatic nerve conduction, significantly prolonged distal latency of CMAP ( P<0.05) and slower nerve conduction velocity ( P<0.05) were observed in the experimental limbs when exposed to microwave radiation at 60 and 80 W, but the decrease of CMAP amplitude was not significant (P>0.05). Pathological examination showed obvious congestion and bleeding in the intercellular spaces of skeletal muscle cells in the experiment group when exposed to radiation at 60 W, with no ob-vious pathological changes found in the sciatic nerve. However, when exposed to radiation at 80 W, vacuoles appeared in myocytes, the cellular structure was destroyed and the myelin sheath of the sciatic nerve swelled. Conclusion Ex-posure to microwave irradiation at 20 and 40 W, but not 60 and 80 W exerts no adverse effects on nerves and muscles adjacent to titanium alloy internal fixation plates. Consequently, continuous wave microwave irradiation at low powers (20~40 W) is a safer auxiliary treatment for limbs with titanium alloy implants.

Objective To study the treatment of a or toiliac occlusive disease and prevention and management of early complications. Methods From Mar 1998 to Mar 2005, 83 aortoiliac arterial occlusion patients were treated with embolectom y by Forgaty catheter as the main therapy for acute occlusion. In cases of chron ic occlusion percutaneous transluminal angioplasty and stenting, prosthesis graf t bypass surgery as well as proximal endovascular procedure combining with dista l arterial reconstructions were adopted on case to case basis. Results There was acute aortoiliac occlus ion in 14 cases, 6 cases (42.9%) suffered from early complications after embole ctomy, with mortality of 7.1%. In chronic aortoiliac occlusion of 69 cases,va rious complications developed in 16 cases(23.2%),of which aortoiliac arteri al stent placement in 17 cases with complications of 23.5%;prosthesis bypass in 23 cases, with complications of 30.4%, and mortality of 4.3%;aortoili ac stenting combining with femoral-popliteal bypass in 29 cases(58 legs)with complications in 5 cases(17.2%). Conclusion The expansion and development of minimally invasive tech niques along with minimal invasive surgery may reduce surgical risks,decrease m obidity and mortality rate.

Objective To evaluate the extra-anatomic bypass surgery for aorto-iliac occlusive disease in the elderly. Methods From January 2005 to December 2008,33 elderly patients/39 limbs (age ranged from 70 to 87 years, mean 76.0 ± 3.0 years) with aortoiliac occlusive disease were retrospectively analyzed. According to Fontaine classification, there were 5 phase Ⅱ b cases (7 limbs), 22 phase Ⅲ cases (26 limbs), and 6 phase Ⅳ cases (6 limbs), all cases were with TASC C, D lesions. Results These 33 cases/39 limbs were tr eated with a variety of bypass, including axillobifemoral bypass (6 cases/12 limbs) ,axillofemoral bypass ( 20 cases/20 limbs ), femorofemoral bypass ( 7 cases/7 limbs ). Intermittent claudication improved in 5 cases, rest pain disappeared in 22 cases, and ulcers healed in 6 cases after operations. The mean ABI increased from 0.29 ± 0.11 to 0.66 ± 0.13 ( t = 2.69, P ＜ 0.05 ). All limbs were salvaged and there was no perioperative mortality within 30 days after operations. Postoperative complication rate was 9.1%. Patients were followed up for a median of 12 ±5 months (range, 6 to 28 months), primary patency rate was 89.7% (35/39), secondary patency rate was 94.9% (37/39), limb salvage rate was 92.3% (36/39). After dischargement the mortality was 6.1% (2/33) with one dying of myocardial infarction and another one of malignant tumor (gastric cancer). Conclusions Extra-anatomic bypass for aorto-iliac occlusive disease in the elderly is feasible, safe and effective, and the cardiopulmonary dysfunctions are the major risk factors for perioperative complications.

Objective To discuss the strategies of prevention and treatment for complications of endovascular therapy in aortoiliac artery occlusive disease.Methods 220 cases who received endovascular interventions with aortoiliac artery occlusive disease were retrospectively reviewed from June 2012 to June 2014.Among these patients,189 cases were males.The age was between 46 to 85yrs and the average age was 64yrs.Results The overall technique success rate was 97.2％.Nine procedure-related major complications requiring additional endovascular or surgical treatment were encountered in 7 patients including 2 acute in-stent thrombosis,1 iliac artery rupture,1 distal embolism,and 5 puncture associated complications (2 acute artery thrombosis,1 arteriovenous fistula,1 hematoma,1 artery dissection).8 cases improved after second endovascular or remedial open surgery,among those 4 cases were managed by endovascular interventions including 2 catheter directed thrombolysis,1 cover-stent implantation and 1 balloon-based angioplasty,4 patients received open surgery including 3 thrombectomies,1 hematoma cleating.After 22 months follow-up,the primary patency,assistant-primary patency and secondary patency was respectively 90.8％,92.1％ and 99.2％.Conclusions More attentions should be paid to the complications of endovascular therapy in aortoiliac artery occlusive disease.Helpful to prevent these complications are a comprehensive evaluation of the lesions,and individualized surgical plan prior to the operations,and a careful intraoperative management.

Objective To evaluate the result of revascularization for lower limb artery ischemia in elder patients. Method During Jan 2006 to Nov 2008, 262 elder patients (60 years old and up), underwent artery revascularization for lower limb arterial ischemia. Mortality, morbidity, primary patency, secondary patency and limb salvage were analyzed. Result There were a total of 323 ischemia limbs in those 262 elder patients undergoing revascalarization, among those 102 limbs underwent artery bypass, 98 limbs underwent endoluminal angioplasty with or without stenting, 67 limbs underwent embolectomy or endarterectomy, 56 limbs underwent open surgery combined with endoluminal treatment due to multiple segment lesions. Operation success rate was 94.7%. Two patients died within 30 days. Perioperative morbidity developed in 15 cases. 245 patients (93.5%) were followed-up from 1 month to 35 months. Mortality was 6.1% (15 cases), primary patency was 80.5%, secondary patency was 92.7% and limb salvage rate was 95.2%. Risk factors analysis showed that history of cardiac disease and elder ages were associated with higher mortality. Diabetes mellitus, critical ischemia and multiple segment lesions were associated with poor long term patency and limb salvage. Conclusion Lower limb ischemia is severe disease related to elder patients' death and amputation. Careful patient selection, detailed pre-operation work-up, meticulous operative technique play crucial roles for a successful arterial reconstruction.

Objective To evaluate the efficacy and safety of perioperative anticoagulation and antiplatelet therapy of carotid endoarterectomy (CEA). Methods A retrospective study on 110 cases (122 CEAs) of carotid stenosis between Jan 2004 and Dec 2008 was undertaken. 122 cases were divided into anticoagulation group and antiplatelet group according to the perioperative medical treatment. Postoperative results of stroke/death and wound hemotoma were compared between the two groups and statistically analyzed. Results 45 CEAs were given perioperative combination of anticoagulation and antiplatelet treatment. This comprised the anticoagulation group. The antiplatelet group consisted of the other 77 CEAs which were treated with antiplatelet solely. Perioperative stroke/death rates were equivalent (2.2% anticoagulation vs. 2.6% antiplatelet, P =0.897). Wound hemotoma rates were found with statistical significant difference between the two groups (13.3% anticoagulation group vs. 1.3% antiplatelet group, P = 0. 006 ). Conclusion Our results suggest that perioperative antiplatelet therapy in perioperative carotid endoarterectomy does not increase perioperative stroke/death risk, while perioperative anticoagulation increases the risk of wound hematoma.
