Objective To investigate the clinical effectiveness of interventional therapy for deep venous thrombosis(DVT) in the lower limbs.Methods A total of 38 patients with DVT were treated by intravenous thrombolysis;12 of them received percutaneous transluminal balloon angioplasty and intravascular stenting after the thrombolysis.According the evaluation criteria of our hospital,the outcomes of the patients were classified as cure(angiography showed complete lysis of the thrombus and smooth venous wall),markedly improved(the deep vein was patent with intravascular mural thrombi,the inner radius was reduced by less than 1/3),improved(angiography showed residual thrombi in the deep vein,and the inner radius was reduced by more than 1/3),and failure(the vein was still obstructed).Results After the treatments,cure was achieved in 22 patients,markedly improved in 14,and improved in 2.No severe complications occurred during the operations.Thirty-four of the patients were followed up for 3-24 months(3-6 months in 7 cases,7-12 months in 12,and 13-24 months in 15).Two patients had recurrence during the follow-up and were cured by intravenous thrombolysis.Conclusion Interventional therapy is continent,effective,and safe for DVT.

Objective:In this study we evaluated the diagnostic value of plasma D-dimer level as an early indicator in acute mesenteric ischemia in rats.Methods:Forty-eight mature male Wistar rats were divided equally into experimental group (EG) and control group (CG),The superior mesenteric artery was ligated In EG,and while a simple laparotomy was performed in CG.Blood samples were taken for laboratory test in both groups at 1h、6h、12h respectively.Results:The longer the duration of mesenteric ischemia,the higher were the serum D-dimer levels in the study groups,and statistical significance was obtained between these two groups (P=0.0375).Otherwise,significant difference was not found in other laboratory parameters between them.Conclusions:Serum D-dimer dynamic measurements may be a important valuable screening parameter in the early diagnosis of mesenteric ischemia.

Objective To explore a new surgical procedure of open reduction and internal fixation for intraarticular fractures of calcaneus and its clinic outcome. Methods Between August 2004 and August 2005, 54 feet in 44 patients with calcaneal fracture were treated in our department. Based on the results of X-ray and coronal CT scan before and after treatment, small incision (2-3 cm) at lateral sides of calcaneus, self-made calcaneal anatomical plate and stud bolt were used. According to Sanders classification system, there were 12 cases of type Ⅱ, 32 cases of type Ⅲand 10 cases of type Ⅳ. Results The internal fixation with the calcaneal anatomical plate almost restored the height, length, width, Blher's and Gissane's angles of the calcaneus for the 44 patients. No infection of incision happened. The results were evaluated using Maryland Foot Score. 54 fractures were followed up for 2 to 12 months (averaging 8.3 months) after treatment. Excellent results were noted in 26 fractures,good in 24,fair in 4, and the excellent and good rates were 92.6%. Conclusion The open-reduction and internal fixation with self-made calcaneal anatomical plate and stud bolt is one of the best ways for treatment of fracture of calcaneus.

From the view of ergonomics study,the importance of optimized design for human-computer coordination work is presented. Through the analysis of probably reasons for the ergonomics accidents in the process of human-computer coordination work,the methods and realization of the optimized design are given out. Furthermore,the studies of human-computer systematization design in preventing the accidents are also discussed.

One child was hospitalized because of repeated cough and sputum. The biopsy diagnosis in local hospital was cystic lymphangioma in retropharyngeal space. We carried out transoral incision and drainage by catheter under general anesthesia. Put into the surgical cavity a suction drainage tube, and injected 5 mg dexamethasone and 8mg Bleomycin. He had nasogastric liquid diet after operation. We removed the suction drainage tube two weeks later. No recurrence was found following up over two years.

Objective To observe the effect of dexmedetomidine in cerebral aneurysm embolization in pa-tients with hypertension. Methods Sixty patients with hypertension undergoing emergency cerebral aneurysm em-bolization were randomly divided into two groups:research group(dexmedetomidine given group) and control group. SBP,DBP,HR,plasma norepinephrine(NE):baseline value(T0),before intubation(T1),after intubation (T2),after extubation(T3). Extubation time and anesthetic-related complications were also recorded. Results The hemodynamic parameters and plasma norepinephrine concentration in the research group were more stable than those in the control group at different time point during perioperative period. There was no difference between two groups about extubation time. The incidence of anesthetic-related complications in research group was lower than control group(P < 0.05). Conclusions Dexmedetomidine can reduce the stress response of intubation ,extuba-tion and perioperative hemodynamic fluctuations in cerebral aneurysm embolization in patients with hypertension. It can also reduce the consumption of prorofol and the incidences of adverse effects.

Based on the first hand cardiothoracic surgical training experiences in Australia, the author introduced the Australian surgical training system's objective, structure, outline and specific training methods as well as its contents in detail. Its overall characters can be summarized as high standard, strict requirement and equal stress on both theory and practice. Hopefully, this introduction and reflection may shed some light on the improvement and evolvement of the resident training system in China.

Objective To explore the value of endovenous laser treatment (EVLT) in treating the variceal ulcer of lower extremities (VULE).Methods Twenty cases of chronic venous insufficiency with VULE were treated with endovenous laser and received regular postoperative follow-up survey.Results No complication,such as burning of skin happened,all superficial varicose veins disappeared,and most of ulcers were healed within 2 -4 weeks after EVLT.Conclusion EVLT is one of the important methods which is minimally invasive and safe to treat VULE.

AIM:To set up a method of simultaneously determining the contents of ephedrine and pseudoephedrine in Zhisou Lixiao Oral Liquid (Herba Ephedrae, Radix et Rhizoma Glycyrrhizae, Semen Raphani, etc). METHOD: The HPLC-quantitative analysis was carried out on a column of Sinochrom ODS-BP by using a mobile phase of acetonitrile-0.02 mol/L potassium dihydrogen phosphate (pH=2.7), (4∶100, with 0.1% triethylamine) under a flow rate of 1.5 mL/min. 207 nm was selected as the wavelength of detector. RESULTS: The linear range of ephedrine was 20.8-208.0 ?g/mL(r=0.999 7) and pseudoephedrine's was 15.0-150.0 ?g/mL(r=0.999 8). The recoveries of them were all between 95% and 105%(RSD

Objective:To investigate the effects of nitric oxide(NO) and inducible nitric oxide synthase (iNOS) in the experimental abdominal aortic aneurysm (AAA) rat model.Methods:An intra-aortic elastase infusion model was used.Control rats received intra-aortic saline infusion.In the remaining groups,intra-aortic elastase infusion was used to induce aneurysm formation.These rats were treated with intraperitoneal injections of saline postoperatively(experimental group),aminoguanidine postoperatively(medicine group).Serum NO and aortic diameter were measured,Changes of histology,iNOS and MMP-9 were observed in the aortic wall.Results:Experimental group produced AAAs with significant production of iNOS,MMPs and serum NO compared with controls.In medicine group reduced aneurysm size and displayed suppression of MMPs expression,inflammatory infiltrates and serum NO production were detected.Conclusion:Expression of iNOS and MMP-9 are induced and serum NO levels are increased in experimental AAA,iNOS and NO production by iNOS play an important role with detrimental effects during experimental aneurysm development.
