ObjectiveTo prospectively evaluate the therapeutic effect of Alvenor on symptoms and signs of chronic venous insufficiency of lower extremities.MethodAccording to preset criteria, 133 patients from 8 hospitals in Hangzhou, Beijing, Guanzhou and Shanghai were recruited into this study including 78 males (58.6%) and 55 females (41.4%). The average age was 23～77 (55?13) years. The illness course was from 1～50 years with a mean of (11?11) yrs. Other therapeutic modalities were adopted in 34 before inclusion into this study and 38 cases (28.8% ) had suffered from certain complications. Classification was first defined when the patient was enrolled and clinical symptoms and signs were evaluated. Alvenor was given 500?mg, twice a day orally. Reevaluation and record by the same criteria was carried out 15, 30, and 60 days after treatment, and statistical analysis was conducted. ResultsSwelling, heaviness, spasm, and pain, etc, were statistically improved. ConclusionsAlvenor is effective in the treatment of symptoms and signs of chronic venous insufficiency of the lower extremities.

Objective To evaluate the clinical application of digital radiography(DR)tissue equalization(TE)technique in the femoral neck injury.Methods TE technique and conventional photography were used to examine 50 patients suffering from injury of the femoral neck.The image quality was evaluated by three radiological experts who were blinded to the results.The image quality was divided into five levels.Results When the TE technique was used,38 perfect images were obtained and there was no unacceptable image,while the traditional methods resulted in 12 unacceptable images and no perfect image.The TE technique is superior to the conventional radiography significantly in the lateral photography of the femoral neck(P

Objective: To investigate the feasibility for reconstructing an aortic arch by a new integrated two-branched stent graft releasing in experimental canine thoracic aorta simulation system.
Methods: A new type of integrated two-branched stent graft was developed and placed in the canine thoracic aorta, the stent graft releasing in a simulated system was conducted under X-ray guidance to monitor the operating process and to explore the feasibility for invitro sent graft releasing.
Results: The new two-branched stent graft was successfully deployed in canine thoracic aorta simulation system. The releasing process was smooth, two small stent grafts were well landing, and all stent grafts were fully expanded and properly positioned.
Conclusion: Our new two-branched stent graft could successfully reconstruct the aortic arch in experimental canine. The thoracic aorta releasing system may better and truly simulate the whole process of endovascular aortic repairing, which provides a good foundation for further animal experiments.

Objective To compare the outcomes of off-pump versus on-pump CABG.Methods From 2002 to 2008,CABG was performed in 105 patients aged 80 years and over,including 45 without cardiopulmonary bypass (CPB) or off-pump (OP) CABG (OPCAB) and 60 with CPB (onpump CABG).The outcomes were compared between two groups.Results The mean ICU stay was (37.1±30.3) h in OPCAB group and (60.6±58.2) h in on-pump CABG group (P＜0.01).Average ventilator-assisted time was (10.8±9.7) h for OPCAB group versus (22.3±35.7) h for onpump CABG group (P＜0.01).Postoperative atrial fibrillation occurred in 31.1％ of OPCABG patients and 41.7 ％ of on-pump CABG patients (P＜0.01).The mortality rate was 5.0％ in OPCABG group versus 8.3％ in on-pump CABG group (P＜0.05).Conclusions OPCABG is a safe and efficient method of myocardial revascularization in the elderly patients with lower morbidity and complications.
