[Objective]To study the effect of arthroscopic reconstruction of anterior cruciate ligament with hamstring tendons and mini-plates.[Method]Thirteen cases of anterior cruciate ligament ruptures were reconstructed arthroscopically with over six strands of hamstring tendons in way of one-bundle and two-tunnel reconstruction.The grafts were fixed with suspension technique by mini-plates.The patients were followed up for one year.The clinical results were evaluated according to Lysholm rating scale.[Result]Twelve patients(92.31%) had negative Lachman test,and one patient showed positive Lachman test.Pivot shift test was negative in 12 cases,and was positive in one case.The Lysholm score increases from 47.77?1.96 to 95.38?4.74(P

Objective To sum up the clinical information and outcomes of one-stage surgical repairs for interrupted aortic arch (IAA) associated with cardiac defects through median stemotomy in infant.Methods From August 2005 to January 2012,23 IAA patients,aged 18 days to 3 years [mean age (8.61 ± 11.81) months],body weight 3.3-13.0 kg [mean (6.61 ± 3.26) kg] were reviewed underwent one-stage repair.There were 12 male and 11 female.The anatomic subtype ineluded type A 20 (87.0％),type B 3 (13.0％),and no type C in the records.All cases included ventricular septal defect and patent ductus artefious,some also with artirical-pulmonary window,aterical septal defect,bicuspid or unicuspid aortic valve,and subvalvular aortic stenosis.Diagnosis was determined in of the patients and suspected in by echocardiography.Also,64 layers helico-CT was employed to make a definite diagnosis for 18 patients and cardiac catheterization was used for 4 patients.All patients with cardiac anomalies underwent one-stage repair through median sternotomy.The aortic continuity was reestablished by anastomosis between the descending aortic segment and aortic arch.Results In all 23 cases,21 were successful.There was 2 (8.69％) postoperative death:one was due to surgical hemorrhage and severe low cardiac output during perioperative stage and the other was 2-month old due to crisis of pulmonary hypertension.CPB time was ranged from 53-215 min [(129.76 ± 38.98) min],and aortic crossclamp time was 34-125 min[(74.47 ± 24.30) min].The length of stay in ICU postoperatively was 96h averagely.The postoperative complications included severe low cardiac output syndrome in 3 patients,hypoxemia in 13,pneumonia in 7,and supraventricular tachycardia in 12.21 patients were followed up from 2 months to 6 years and were in good condition without recoactation.Conclusion The outcomes of early and medium term for one-stage repair of IAA and associated cardiac anomalies through median stemotomy is excellent.Technique of extended anastomosis between the descending aortic segment and aortic arch may reduce the incidence of recoarctation.It is simplified the procedure and improved life quality of patients.

Objective:To investigate the diagnostic value of vaginal color Doppler flow parameters in patients with epithelial ovarian cancer in different FIGO staging.Methods:178 patients with ovarian tumors who were treated by surgery in Dingzhou People’s Hospital from Jul. 2016 to Jul. 2022 were selected, and they were divided into ovarian cancer group (65 cases) and ovarian cyst group (113 cases) according to the results of postoperative pathological diagnosis. According to FIGO staging standards, ovarian cancer was divided into FIGO stage I (18 cases) , FIGO stage II (16 cases) , FIGO stage III (16 cases) and FIGO stage IV (15 cases) . The blood flow parameters of vaginal color Doppler ultrasound were measured, including arterial pulsatility index (PI) , end diastolic flow velocity (EDV) , resistance index (RI) , peak flow velocity (PSV) , serum vascular endothelial growth factor (VEGF) and human epididymal epithelial secretory protein 4 (HE4) . The levels of PI, EDV, RI, PSV, VEGF and HE4 were compared between the two groups and patients with different FIGO stages, and the value of ROC analysis of vaginal color Doppler flow parameters in predicting the occurrence of ovarian cancer was analyzed. The correlation between FIGO stage and vaginal color Doppler flow parameters and serum VEGF and HE4 levels was analyzed by person coefficient.Results:PI and RI levels in ovarian cancer group were (0.79 ± 0.15) , and (0.39 ± 0.12) , lower than those in ovarian cyst group (1.51 ± 0.17) , (0.72 ± 0.16) ; EDV, PSV, HE4, VEGF levels were (13.88 ± 4.18) cm/s, (25.61 ± 4.53) cm/s, (283.92 ± 28.97) pmol/L, and (372.55 ± 38.96) ng/mL, higher than those in ovarian cyst group ( P<0.05) . According to ROC analysis, the best cutoff values of transvaginal color Doppler blood flow parameters for predicting the occurrence of ovarian cancer were PI<1.235, EDV≥10.985 cm/s, RI<0.580, PSV≥22.975cm/s, all P<0.05. The levels of PI and RI in patients with different FIGO stages showed a decreasing trend with the increase of the severity of the disease, while the levels of EDV, HE4 and VEGF showed an increasing trend ( P<0.05) . There was no significant difference in PSV levels between patients with different FIGO stages ( P>0.05) . The correlation analysis showed that FIGO stage was positively correlated with the blood flow parameters EDV and the levels of serum HE4 and VEGF. FIGO stage was negatively correlated with PI and RI ( P<0.05) . Conclusions:There were significant differences in the levels of PI, RI and EDV in patients with ovarian cysts and ovarian cancer at different FIGO stages. The levels of PI, RI and EDV are closely related to the malignant degree of ovarian cancer.

Objective To analyze the operation of long-term effect of edge to edge mitral repair for mitral vavle moderateto-severe insufficiency in children retrospectively.Methods Clinical dates of 102 patients who underwent edge to edge mitrel valve repair in Nanjing Children's Hospital from March 2003 to March 2015 were collected.Postoperative thoracic echocardiography was adopted to observe the effect of mitral valve forming and evaluate the follow-up results.Results The whole group of 2 patients died in hospital,Followed up for 1 months to 12 years,during the follow-up of 10 patients were lost.The early fol low-up,medium-term follow-up and long-term follow-up were completed 93,55 and 26 cases,respectively.In the early followup,6 patients had recurrent moderate mitral regurgitation(MR),and 5 patients had recurrent moderate-to-severe MR and reoperated during the follow-up period,a total of 2 cases died.In the medium-term follow up,moderate and severe MR were found in 6 and 4 cases,respectively.Three patients accepted reoperation,two patients died.In the long-term follow-up,1 case had recurrent severe MR,2 cases had re-operation and had no death.Early survival rate was 97.8 ％ (91/93),avoid reoperation rate was 94.6％ (88/93).The incidence of moderate or severe mitral regurgitation was 11.8％ (11/93).Midtcrm survival rate was 96.4％ (53/55),avoid reoperation rate was 94.6％ (52/55),moderate or severe mitral regurgitation rate was 18.2％ (10/55).Long-term follow-up have no death,avoid reoperation rate was 92.3 ％ (24/26),mitral valve moderate and above reflux rate was 7.7 ％ (2/26).The actuarial survival and freedom from MV reoperation rate was (92.4 ± 2.4) ％ and (77.7 ± 6.4) ％ at 10 years,respectively.Conclusion Edge to edge mitral repair in the treatment of children with moderate to severe mitral insufficiency had relatively stable curative effect,relatively fewer complications,and high long-term clinical effect.

OBJECTIVETo compare the efficacy of thoracoscopic surgery versus thoracotomy in repairing esophageal atresia type Ⅲ with tracheoesophageal fistula (EA/TEF) in neonates.

METHODSA retrospective analysis was conducted in 97 neonates who underwent EA/TEF repair between January 2012 and December 2017 in the Affiliated Children's Hospital of Nanjing Medical University, including 75 patients receiving thoracotomy and 22 patients receiving thoracoscopic surgery. The perioperative data and the incidence of early postoperative complications were compared between two groups.

RESULTSThe operations were completed in all patients. One child (4.5%) in thoracoscopic surgery group was converted to thoracotomy with modified Livaditis procedure due to the long distance of two blind ends (>4 cm) and thinner distal end. The operation time was longer in thoracoscopic surgery group[(143±48) min vs. (120±40) min, <0.05], but the postoperative ventilation time was shorter[(55±22) h vs. (65±19) h, <0.05] and the first oral feeding was earlier in thoracoscopic surgery group[(3.2±1.1) d vs (3.9±1.3) d, <0.05]. No statistical difference was observed in the ratio of red blood cell transfusion, length of hospital stay and drainage tube indwelling time between two groups (all >0.05). The incidence of lung complications in thoracotomy group was higher than that in thoracoscopic surgery group (20.0% vs. 9.1%, <0.01), while there were no significant differences in the incidence of other postoperative complications between two groups. There was no death in thoracoscopic surgery group, while 2 patients died in thoracotomy group.

CONCLUSIONSThoracoscopic repair is a preferred surgical procedure for EA/TEF in neonates.
