Objective To evaluate the efficacy of ventricle septal defect(VSD) occluder through lower ministernotomy for patients with perimembranous VSD. Methods From January 2007 to August 2008,41 patients with perimembranous VSD(14 male,27 female,weighed 9.0 to 71 kg with a mean of 46.3?16.1) underwent a closure of perimembranous VSD through lower ministernotomy using Amplatzer occluder.Before the operation,all the cases had been confirmed as having a 3-to 8.5-cm perimembranous VSD by transthoracic echocardiography(TTE).Under general anaesthesia,a small incision was made at the lower sternum to expose the right ventricle,and then occluder was placed in the right ventricle.TEE,electrocardiography and chest X-ray were performed before discharge and 1 month after the operation.Results The procedure was completed successfully in all the patients with a mean operation time of(6.2?3.3) hours(ranged from 2.5 to 17 hours).The ICU stay was(15.1?4.3) in average(8-21 hours).The mean drainage volume after the surgery was(80?33) ml(35-210 ml).Follow-up was available in all the cases for(7.9?4.1) months(range,3-15 months).During the period,no A-V block,new AI,occluder displacement,embolization,tricuspid incompetence or residual occurred. Conclusions VSD occluder is feasible and safe for closure of perimembranous ventricular septal defects through lower ministernotomy.

Objective To discuss factors influencing the heterotopic ossifications (HO) after treatment of bi-column acetabular fractures. Methods One hundred and ninety-three cases of bi-column acetabular fractures were followed up, including 147 males and 46 females with an average age of 34. 4 years. Thirty-one cases were associated with craniocerebral trauma. The interval between injury and surgery was less than 1 week in 15 cases, 1 to 2 weeks in 121 cases, 2 to 3 weeks in 34 cases, and over 3 weeks in 23 cases. Factors that might have influenced HO, including surgical method, associated injury, and interval between injury and surgery, were analyzed retrospectively. Results All the cases were followed up for an average of 44. 2 (14 to 84) months. The mean operation time was 238 (150 to 330) minutes, and the average blood loss was 1453 (450 to 4400) mL. The incidence rate of HO was 39. 9% (77 in 193 cases), including 39 cases of degree one, 23 cases of degree two, and 15 cases of degree three. Of the 77 cases associated with HO, 14 had craniocerebral trauma and 63 did not (χ~2 = 0. 019, P = 0. 891) . HO was found in 2 cases that had been operated on in less than 1 week, 38 cases in 1 to 2 weeks, 21 cases in 2 to 3 weeks, and 16 cases in over 3 weeks. The Spearman correlation analysis between HO degree and clinical result showed no correlation ( R = 0. 041, P =0. 722). Only 15 cases (7. 8% ) were associated with HO after the debridement of the necrotic gluteus minimus. Conclusions HO after surgery for bi-column acetabular fractures may not be correlated with craniocerebral trauma, but highly correlated with the interval between injury and surgery. Debridement of necrotic gluteus minimus and other muscles can reduce the incidence of HO.

Objective To explore the expression and significance of hsa-miR-181a (miR-181a) in can-ceration progression of endometrial carcinoma. Methods A total of 75 formalin-fixed paraffin-embedded tissue specimens were studied in this study , of which , 13 were normal endometrium , 18 were endometrial hyperplasia , 44 were endometrial carcinoma. After total RNA had been extracted , real-time PCR was applied to detect the ex-pression level of miR-181a in endometrial tissue in each group. Results miR-181a expression in formalin-fixed paraffin-embedded tissue specimens can be detected. Expression of miR-181a in endometrial carcinoma was high-er than that in endometrial hyperplasia , its expression in endometrial hyperplasia was also higher than that in normal endometrium, and the difference was statistically significant (P < 0.05). The expression of miR-181a in endometrial carcinoma was associated with FIGO stages (P < 0.05). Conclusion The up-regulation of miR-181a expression in women with endometrial carcinoma may play the role of oncogenes. Abnormal expression of miR-181a is probably associated with the occurrence and development of endometrial carcinoma.
