BACKGROUND:Restenosis easily occurs after stent implantation,thus it is worthy optimizing the stent design and evaluating its structural safety.OBJECTIVE:To simulate the deformation of balloon-expandable stainless steel stents by the finite element method,and calculated the radial displacements and stresses after expansion in different designs.DESIGN:A comparative calculated analysis.SETTING:Laboratory of Laser Processing Technology,South China Normal University.MATERIALS:The experiment was carried out in the Laboratory of Laser Processing Technology,South China Normal University in October,2006.The model of slotted-tube stent was used.METHODS:The simulations were carried out to expand a stainless steel stent with 2 mm in outer diameter,10 mm in length and 0.09 mm in strut width.Due to the symmetry of the stent by utilizing the correct boundary conditions,a half model was used to simulate the deformation process.①In stent I,the slot length was 2.0,4.0 and 4.0 mm for a,b and c respectively.In stent Ⅱ,the slot length was 1.5,4.5 and 4.0 mm for a,b and c respectively.In stent Ⅲ,the slot length was 1.8,4.2 and 4.0 mm for a,b and c respectively.Three points(A,B and C)in vary strut were selected to study the displacement during the process of deformation.The pressure applied as a surface load on the inner stent surface was 0.5 Mpa.②The dimensions and radial displacements of the three stent designs in the process of expansion were calculated,and the changes of deformation stresses were observed in the third design.MAIN OUTCOME MEASURES:① The dimensions and radial displacements of the three stent designs in the process of expansion were calculated;②The changes of deformation stresses were observed in the third design.RESULTS:The shape of the expended stent I looked like a dumbbell.The maximum radial displacement of point C obtained is found to be 2.1 mm,and the point B obtained the smallest radial displacement of 0.3 mm in the three defined points.In stent Ⅱ,the maximum radial displacement obtained is found to be point B of 2.1 mm,and the point C obtained the smallest radial displacement of 1.20 mm in lhe three defined point,which obtained a spindly shaped stents.In stent Ⅲ,the maximum radial displacement obtained is found to be point B of 2.2 mm,and the point A obtained the smallest radial displacement of 1.85 mm in the three labeled point,which produce more uniform expansion than the last two stent designs.②In stent Ⅲ,the stresses and the radial displacements achieved as the pressure increased gradually.CONCLUSION:The stress concentrations and the uniformity of the expanded stent can be decreased through optimizing the stent design by finite element method,which can be used in optimizing the stent design and evaluating the structural safety of stents.

Objective To compare the efficiency of repairing perimembranous ventricular septal defect (VSD) with continuous stitching to that with interrupted stitching. Methods Of the 158 patients with perimembranous VSD ( 54% males) ,102 ( 65% ) patients underwent the repairing of continuous stitching (continuous group) ,and 56 patients underwent interrupted stitching (interrupted group). All the surgeries were performed under hypothermic cardiopulmonary bypass. Results The cardiopulmonary bypass time and aortic cross-clamp times were (31 ±14) mins and (18 ±12) mins in the continuous group, which was significantly less that those of (42 ± 16) mins and (25 ±11) mins in the interrupted group (t =4.49 and 3. 61 .respectively ,P <0. 05) . No case was died. The main complications involved temporary M atrioventricular block (AVB) of two cases (1 case in each group),which disappeared after 1 week. There were two remnants remaining leak (n =2) which was less than 3 mm and automatically cured after 3-6 months. Complete right bundle branch block(CRBBB) occurred in 3 cases in the continuous group and 6 cases in the interrupted group,of which 3 disappeared after 1 month and 2 disappeared after 12 months. The outcome was good in all cases after 1-3 years follow up. Conclusions Continuous stitching showed a shorter cardiopulmonary bypass and aortic cross-clamp times, and reduced the CRBBB.

Objective To investigate the effects of etomidate and propofol on circulatory system and the depth of anesthesia in laparoscopic surgery of ectopic pregnancy.Methods From January 2014 to January 2015, 40 patients with ectopic pregnancy in our hospital were selected and divided into the etomidate group and propofol group according to the principle of complete random grouping.Patients in the etomidate group received etomidate induced anesthesia, and the patients in the propofol group received propofol induced anesthesia.Hemodynamic parameters and bispectral index(BIS) of two groups were evaluated at 4 time points.The incidence of postoperative nausea and vomiting, chills and bronchospasm were recored.Results There was no significant difference in heart rate (HR),systolic blood pressure (SBP) and diastolic blood pressure(DBP) between the two groups at T0,T2and T3.But at the time of induction(T1), the heart rate of patients in propofol group was significantly lower than that in etomidate group(P<0.05).While T1, compared with etomidate group, the HR and SBP significantly decreased and DBP increased in the propofol group (P<0.05), The HR and SBP at T1of patients in the propofol group and etomidate group decreased significantly and DBP increased when compared with T0(P<0.05).and etomidate group decreased significantly compared with T0 ( P <0.05 ).There were no significant differences in BIS indexes at four time points.However, BIS indexes at T1 ,T2 and T3 were significantly lower than T0 ( P <0.05 ).There was no significant difference in three kinds of complications rates in two groups.Conclusion Etomidate, compared with propofol, can better control the cardiovascular response during induction of anesthesia.Both drugs have a consistent depth of anesthesia.There is no difference in the incidence of complications.Etomidate is more suitable for patients with ectopic pregnancy laparoscopic surgery.

Objective To evaluate the efficacy of inspiring carbogen and low concentration oxygen combined with late coupe accelerated hyperfraction radiotherapy on esophageal carcinoma.Methods 74 patients with esophageal carcinoma were randomly divided into two groups:the trial group and the centrol group,which consisted of 37 patients respectively.6MV X-ray was employed in the two groups.The schedule of the trial group was as following:conventional radiotherapy of 1.8～2.0Gy per day was employed during the first phase to a total dose of 38～40Gy,followed by late course accelerated hyperfraetion radiotherapy(twice fractions per day,interval between two fractions more than 6 hours,1.3～1.4Gy per fraction,middle total dose of 64.2Gy).Carbogen and low concentraetion oxygen was inspired during the course of radiation.Results 71 patients were enrolled.At the end of radiation at a total dose of 38～40Gy,complete remission rate(CRR)in the trial group was 31%,whereas that in the control group was 19%(P＞0.05),when the whole radiotherapy was finished,the CRR was 57%and 31%(P＜0.05)respectively,and one month after radiotherapy.the CRR was 71%and 33%respectively(P＜0.01).Six months after radiotherapy,the CRR WaLa 74%and 36%respectively(P＜0.01).Thelocal controlrate of sixmonthswas 91% and 72% respectively in the two groups(P＜0.05).Conclusions Inspiring carbogen and low concentration oxygen combined with late course accelerated hyperfraction radiotherapy may sigllificantly improve short-term efficacy and local control rate in esophageal carcinoma patients in Ⅰ～Ⅲstage.Furthermore,its side effects can be tolerated,and its elongating life time of patients may be prognostic.
