ObjectiveTo investigate the effect of operation treating spinal multi-level tuberculosis.Methods45 patients with multi-level spine tuberculosis were treated with debridement completely and anterior or lateral-anterior intervertebrae autograft. Of them, 5 patients added to anterior instrumentation.Results45 patients had been followed up for 12 to 40 months.The back pain of 40 cases were relieved within 5 weeks after operation, erythrocyte sedimentation rate decreased 3 weeks after operation. 38 patients who involved in kyphosis decreased their kyphosis mostly and only one patient lost 3 degrees in follow-up.15 patients who involved in neurological deficits improved one or two grades (Frankel). Grafts fused in 44 patients and there were no recurrent in follow-up.Conclusions Operative treatment is efficacious to multi-level body spine tuberculosis.

Objective To observe the inhibitory effect of pyridoxine hydrochloride (PN) combined with common chemotherapeutics on mice hepatoma cells H22 in vitro. Methods MTT assay was used to determine the effects of PN in combination with 10 different antineoplastic agents on H22 cells, and immuno-histochemistry was used to observe the distribution of PN in H22 cells and morphologic changes of the cells before and after PN treatment. Results After 24 hours incubation with 5 mmol/L PN, the treated cells expanded apparently with nucleus chipping. PN entered the tumor cell and was mainly condensed in cytoplasma and H22 cells were sensitive to PN. When administered concomitantly with chemotherapic agents, most of the combinations showed antagonistic effects while a few of the combinations were additive. For instance, doxorubicin (ADM) used in combination with PN inhibited cell proliferation with an IR value (IR=0.63) much lower than ADM alone (IR=0.71, P<0.01), and the CI value was less than 0.9, which indicated an antagonistic effect. However, PN in combination with ifosfamide (ICTX) showed additive effect (CI>0.9), and the IR value (IR=0.60) in combined group was higher than that (IR=0.40) in ICTX group (P<0.05). Conclusion PN treatment could increase the intracellular PLP level and result in growth inhibition and cell death, and combined administration of PN and ICTX might be a potential method to improve efficacy and to reduce toxic effects while a co-administration of PN and ADM should be avoided.

Objective To explore the relationship between the endovascular aortic repair (EVAR)in patients with abdominal aortic aneurysm (AAA) and postoperative systemic inflammatory response syndrome (SIRS).Methods In this study,93 AAA patients undergoing EVAR were enrolled.Analysis was performed to evaluate the incidence of SIRS during peri-operation period.Logistic multiple regression analysis was performed to determine the parameters predicting SIRS.Results The incidence of SIRS was 58.1％.Aneurysm size,mural thrombus,iliac artery lesion,number of stent,operating time,volume of contrast agent,blood loss and length of stay were all significantly correlated with SIRS (P ＜ 0.05).In a logistic regression model,history of kidney disease or operation,aneurysm size,ruptured aneurysm and number of stents were strongly and independently associated with SIRS.Conclusions SIRS is common in AAA patients after EVAR.Optimizing treatment strategies avoiding risk factors for SIRS benefits AAA patients.

Objective To probe into the reasons for and results of remedial surgical therapy in thoracic aortic dissection patients after first endovascalar repair.Methods From July 2000 to December 2012,12 cases received second interventional surgery.The average time from second therapy to first surgery was ( 14 ± 11 ) months.Main reasons for second endovascular therapy were sustained type Ⅰ endoleak at proximal landing zone and type A dissection caused by retrograde tear.Therapies included hybrid operations in 8 cases and absnlute endovascular therapy in 4 cases.Results The 30 day mortality after the second intervention was 5.6％ ( 1/12),total mortality rate was 16.7％ (2/12).In 7 cases with endoleak,small endoleak remained after remedial therapy (57.1％ ) in 4 cases.Among 4 cases with secondary type A aortic dissection,successful staged hybrid operation with mid-sternal thoracotomy was adopted in 3 cases,one died of pulmonary emtbolism during follow-up period,1 case with Bebcet disease still had proximal type Ⅰ endoleak after second hybrid operation,and died from tear of aorta.Conclusions Endoleak and secondary type A aortic dissection are the main cause necessitating second intervention after primary endovascular therapy for thoracic aortic dissection.Hybrid operation remains the best choice to treat postoperative complications after endovascular therapy for thoracic aortic dissection.

Objective To determine the influence of hostile neck anatomy on type Ⅰ a endoleak development after endovascular aortic aneurysm repair (EVAR) for infrarenal abdominal aortic aneurysmal disease.Methods From July 2008 to July 2011,195 consecutive patients with non-ruptured abdominal aortic aneurysms (AAA) were treated with EVAR.There were 150 males and 45 females,aging from 52 to 95 years with a mean of 69 years.Forty-three patients were with hostile neck anatomy ( HNA ).High-resolution computed tomography was abtained in all patients,with detailed measurement of proximal neck parameters.Univariate and multivariate analyses were used to compare Ⅰ a endoleak and HNA.Follow-up protocol consisted of computed tomography (CT) angiograms or ultrasound at 3,6,and 12 months,and annually thereafter.Results Twenty-three patients had intraoperative type Ⅰ a endoleaks.The adjunctive measures,such as repeated balloon angioplasty,cuff extension,Palmaz stent placement and chimney technique were used for treating type Ⅰ a endoleak.Small endoleak remained in only one patient.The technical success rate was 98.5％ (192/195).The association between type Ⅰ a endoleak development and magnitude of the infrarenal angle was statistically significant.The mean follow-up time was ( 18 ± 3 )months.The survival rates at 1- and 3-year were 97.4％ and 89.2％ respectively.Conclusions The proximal neck angle is related to intraoperative type Ⅰ a endoleak occurrence,but other factors often thought to be indicative of adverse neck anatomy are not significant predictors.Most type Ⅰ a endoleaks in this study were uccessfully eliminated intraoperatively with a satisfactory mid to long term results.

Objective To evaluate early results of Endurant stent-graft in the treatment of abdominal aortic aneurysms (AAAs).Methods From July 2010 to June 2011,68 patients (57 men,11 women; mean age 74.3 years) were treated with Endurant stent-graft at our center.26 cases had hostile proximal neck in the anatomy.According to ASA classification,15 cases were class Ⅱ ; 32 cases were class Ⅲ and 21 cases were class Ⅳ.Results Intraoperative immediate technical success was achieved in all cases.At completion angiography,a type Ⅱ endoleak was detected in 18 (26％) of the 68 patients.The mean operation time was (96 ± 29) min,the mean blood loss was (99 ± 68 ) ml,and the mean contrast usage was (122 ± 65) ml.No intraoperative conversion to open surgery,stent migration,types Ⅰ/Ⅲ endoleak,other major complications,or death was encountered.49 patients (72％) had a postimplantation syndrome with fever,leukocytosis,and increase of C-reactive protein levels,which completely resolved within two weeks.The mean follow-up time was (8 ± 5) months.Conclusions Endurant stent-graft seems to be safe and effective in endovascular aneurysm repair,even in patients with hostile aortoiliac anatomy.

Objective To compare selective coverage and chimney technology of the left subclavian artery (LSA) in thoracic endovascular aortic repair (TEVAR).Methods Eighty-one cases were retrospectively reviewed from January 2005 to January 2013 with two different management of the LSA during TEVAR:selective coverage (SC) vs chimney (C).Technical success rates,operating time,endoleaks,and perioperative cerebrovascular accidents,spinal cord ischemia (SCI),left arm ischemic symptoms and mortality were analyzed.The survival rate was also evaluated.Statistical analysis was performed using the x2 test,t-test and Kaplan-Meier survival curve.Results There were 37 patients in group SC and 34 in group C.Operating time was (61 ± 22) min for SC,and (101 ± 20) min for C (P =0.000) ; left arm ischemic symptoms occurred in 23.4％ in group SC,and 2.9％ in group C (P =0.011).Technical success rates were 100％ and SCI were 0 for both SC and C.Endoleaks,perioperative cerebrovascular accidents,and mortality were similar between the two groups.Conclusions During TEVAR,selective coverage of the left subclavian artery is safe,effective; meanwhile,chimney technology is safe,effective for patients whose left subclavian arteries need revascularization.

Objective To evaluate the feasibility of chimney technique during thoracic endovascular aneurysm repair(TEVAR) in aortic arch lesions. Methods The stent-graft was deployed covering super arch branch artery in arch lesions in case there was not enough landing zone. A chimney stent was put in the super arch branch artery. We retrospectively analyzed the data of this group, aiming at summarizing the indications, methods, results and complications of chimney technique. Results From August 2004 to August 2009, 27 aortic arch lesions were treated by TEVAR with chimney stent, male/female ratio was 25/2, average age was 67. 2 ±3. 8 years, including3 chimney stents for innominate artery, 11 chimney stents for left common carotid artery and 13 chimney stent for left subclavian artery. Type I endoleaks were encountered in 18. 5% (5/27) of this group by final angiogram. Left common carotid artery dissection was caused by puncture in one case. One patient died of respiratory failure. There was no postoperative stroke nor bleeding. Discharged patients were followed up from 3 to 60 months, averaging at 16. 8 months. There was one death from MI 4 years later. There was minor stroke and left subclavian artery chimney stent occlusion in one each cases during the follow-up. All endoleaks were sealed without stent migration. Conclusion Chimney technique improves the length of landing zone and decreases effectively the endoleak rate.
