Objective To investigate the diagnostic value of MRI in the infantile developmental dislocation of the hip.Methods Forty-five cases of preoperative hip MRI data of DDH (patient group)and 40 cases of normal hip (control group)MRI data were retrospectively analyzed.Three types were classified according to the standard of Dunn.Then the bony acetabular index (BAI),cartilaginous acetabular index (CAI)were measured on coronal MRI and all the intra-articular structures (articular cartilage,labrum, teres ligament and iliopsoas)in the acetabulum that impeded the reduction of the femoral head were observed.Results There were normal hips (80 hips)and dislocated hips (73 hips).In dislocated hips typeⅠ (30 hips),typeⅡ (20 hips),and typeⅢ (23 hips) were found.The values of BAI were (26.13±2.19)°and (35.87±4.42)°,CAI (13.84±1.07)°and (21.92±4.70)°for patient group and control group.The values of BAI were (31.80±1.74)°,(37.80±3.40)°and (39.17±4.11)°,CAI (17.20±2.68)°,(20.91±2.02)°and (27.50±2.78)°for the typesⅠ,Ⅱ,Ⅲ respectively.Differences of BAI and CAI between patient group and control group were showed (t=-11.048 and -9.188,P =0.000).Statistically significants were found among the typeⅠ,Ⅱ,Ⅲ(F=22.159 and 47.241,P =0.000).There were linear correlations for patient group ,control group,and the typeⅠ,Ⅱ,Ⅲ (r= 0.964,0.844,0.953,0.931 and 0.870,P =0.000).Some pathological changes such as varus labrum,thick teres ligament,iliopsoas spasm,articular cartilage hyperplasia,fat hyperplasia,joint effusion were observed in the type Ⅱand Ⅲ.Conclusion MRI is not only used for measuring the values of BAI and CAI,and a linear correlation among all kinds of DDH,but also some factors hindering the reduction of the femoral head can be found clearly.It can provide an important reference basis for the diagnosis and treatment of DDH.

OBJECTIVETo investigate clinical outcomes of tendon allograft reconstruction with arthroscopy minimally invasive technique at stage I for the treatment of knee dislocation with multiple ligaments injury.

METHODSForty-eight patients with knee dislocation were reconstructed anterior and posterior ligament under arthroscopy at stage I from January 2008 to January 2012, and repaired ligaments injury of knee joint by minimally invasive technique. There were 38 males and 10 females aged from 20 to 59 years old with an average of 35.6 years old; 22 cases on the left side and 26 cases on the right side; the time from injury to operation ranged from 2 d to 2 weeks. Two cases combined with anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL) and posterolateral complex injuries, 36 cases combined with ACL, PCL, and MCL injuries, 10 cases combined with ACL, PCL and PLC injuries; 4 cases combined with peroneal nerve injury. Lysholm scoring were used to compared the cases before operation and final following-up to evaluate knee function.

RESULTSAll patients were followed up from 12 to 30 months with an average of (18.2 ± 6.3) months. Activity and stability of joint were obviously improved. Lysholm score were improved from 40.3 ± 4.1 before operation to 87.0 ± 6.4 at final following-up.

CONCLUSIONReconstruction with arthroscopy minimally invasive technique at stage I for the treatment of knee dislocation with multiple ligaments injury could recover stability of joint better,reserve joint function. Preoperative training and postoperative individualized rehabilitation treatment is the key point of recover knee joint function.

Objective This study aims to evaluate the initial results of a hybrid procedure for treating descending thoracic aortic disease that involves distal aortic arch.It also intends to report our initial experience in performing this procedure.Methods A total of 45 patients(35 males and 10 females) with descending thoracic aortic disease underwent a hybrid procedure,namely,thoracic endovascular aortic repair(TEVAR) combined with supra-arch branch vessel bypass,in our center from April 2009 to August 2014.Right axillary artery to left axillary artery bypass(n =20) or right axillary artery to left common carotid artery and left axillary artery bypass(n =25) were performed.The conditions of all patients were followed up from the 14th month to the 77th month postoperative[mean(38.0 ± 17.1) months].Mortality within 30 days,complications such as endoleak after the hybrid procedure,and stenosis or blockage of the bypass graft during the follow-up period were assessed.Results One case of death and one case of cerebral infarction were reported within 30 days.Two patients underwent open surgery beacuse of endoleak.And a newly formed intimal tear was observed in one patient and the patient underwent a second TEVAR during the follow-up period.Condusion Initial results suggest that the one-stage hybrid procedure is a suitable therapeutic option for thoracic aortic pathologies that involve distal aortic arch.However,this procedure is not recommended for type-B aortic dissection,in which a tear is located in the greater curvature or near the left subclavian artery,because of the high possibility of endoleak occurrence.

Objective To obtain an acellular matrix from bovine pericardial tissue, as a scaffold for tissue engineering of heart valves or cardiovascular patching applications. Methods A four step detergent and enzyme link extraction procedure was practiced in this study. The mechanic properties of the acellular matrix were evaluated, and the components were analyzed biochemically. Results HE staining confirmed the removal of cells and Von Gieson staining showed the integrality of collagen and elastin. Biochemical analysis demonstrated the retention of collagen and some glycosaminoglycans while the percentage of the soluble proteins reduced slightly. The tissue fracture strength and shrinkage temperature made no significant differ ence after extraction. Conclusions The extraction process is effective to remove cells from bovine pericardial tissue while maintains its mechanical strength. This approach may eventually lead to a scaffold for heart valves and cardiovascular patching applications in tissue engineering.

PURPOSE: This study was designed to investigate the role of taurine-upregulated gene 1 (TUG1) in MCF-7 breast cancer cells and the molecular mechanism involved in the regulation of microRNA-9 (miR-9). METHODS: The expression of TUG1 in breast cancer tissues and cells was evaluated using quantitative reverse transcription polymerase chain reaction. Cell viability was examined using a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay; cell cycle progression and apoptosis were analyzed using flow cytometry. A dual luciferase reporter assay was used to detect the relationship between TUG1 and miR-9. The expression of methylenetetrahydrofolate dehydrogenase 2 (MTHFD2) was measured by western blot. RESULTS: Higher expression of TUG1 was observed in breast cancer tissues and cell lines than in the corresponding controls. TUG1 knockdown reduced proliferation, suppressed cell cycle progression, and promoted apoptosis of MCF-7 cells. The dual luciferase reporter assay showed that TUG1 could negatively regulate the expression of miR-9. MiR-9 inhibition abrogated the effect of TUG1 knockdown on the proliferation, cell cycle progression, and apoptosis of MCF-7 cells. TUG1 positively regulated the expression of MTHFD2 in breast cancer cells. CONCLUSION: TUG1 knockdown was significantly associated with decreased cell proliferation and it promoted apoptosis of breast cancer cells through the regulation of miR-9.

Objective To evaluate the dynamic contrast-enhanced MRI (DCE-MRI)in detecting experimentally induced testicular ischemia. Methods Thirty healthy male New Zealand rabbits were randomly assigned into 6 groups. There were 5 rabbits in each of the following experimental groups: ( 1 ) Normal control, (2) Sham-operated, (3) ischemia of 3 h group, (4) ischemia of 6 h group, (5) ischemia of 12 h group, (6) ischemia of 24 h group. In all experiment groups, the right testis served as the internal control while the left testis served as the experimental side. DCE-MRI for each animal lasts about 10 minutes. Signal enhanced ratios (SERs) of ROI for both sides of each group were calculated by a computer, and parameters of SERs of 30 s, 75 s, 120 s and maximal SER were used for statistical analysis.Time intensity curves (TICs) were made for two sides of each group via Excel 2003 software and classified into 4 types. Statistical analysis was performed to compare the differences of SERs between left and right testis by two independent Kolmogorov-Smirnov test. Results In group I and 2, significant enhancement was observed on both testes of 10 rabbits. The enhancement decreased gradually with the elongation of ischemia in torsion groups. Three cases of type Ⅰ and 2 cases of type Ⅱ were observed in group 1,5 cases of type Ⅰ in group two, 2 cases of type Ⅰ and 3 cases of type Ⅱ b in group three, 2 cases of type Ⅰ and 2 cases of type Ⅱ b in group four, 5 cases of type Ⅱ b in group five and 5 cases of type Ⅲ in group six were noticed in the left testes. And in TICs of right testes, all cases showed TICs of type Ⅰ except 2 cases of type Ⅱ a in group six. In four torsion groups, the values for SER75 of the left side were 0. 084%, 0. 076%, 0.164% and 0.065%, while the right side were 0.255%, 0.410%, 0.586% and 0.302% (P ＜0.05). The values for SER120 in group three, five and six were 0.221% , 0.158% and 0.059% for the left side, and 0.405%,0.522% and 0.207% for the right side(P ＜0.05). The values for MSER in group three, five and six were 0.217% ,0.164% and 0.072% for the left side, and 0.405%, 0.586% and 0.302% for the right side(P ＜0.05). Conclusion DCE-MRI technique may be useful in the diagnosis of testicular torsion, which shows potential in the clinical application.
