International Journal of Surgery 2013;40(9):611-614,封3
Objective To find out the correlation between MMP-13 and clinicopathological parameters of breast cancer and identify clinical significance of MMP-13 overexpression on overall survival of breast cancer.Methods Immunohistochemistry was performed on paraffin-embedded tissue microarray containing 159 tissue dots from breast cancer patients.The intensity and the extent of IHC were scored by pathologists blind to clinicopathological parameters of the specimens.Different expression profiles of MMP-13 in breat cancer tissues and paraneoplastic tissues,and correlation between MMP-13 and breast cancer clinicopathological parameters were analyzed for statistical significance respectively.The impact of MMP-13 overexpression on overall survival of breast cancer.Results MMP13 expression were significantly higher in breast cancer tissues(54.4%) than in their corresponding paraneoplastic tissues(27.5%)(P =0.003).Expression of MMP-13 in breast cancer positively correlated with lymphma node metastasis(r =0.257,P =0.006),clinical TNM classification (r =0.310,P =0.001),HER2 expression (r =0.192,P =0.041).However,no significant correlation were oberserved between MMP-13 expression and tumor size,MMP-13 expression and tumor grade,MMP-13 expression and ER expression,MMP-13 expression and PR expression respectively.Conclusions Overexpress of MMP-13 is more common in breast cancer tissues than in their corresponding paraneoplastic tissues,and is an independent prognosis indicator of breast cancer.
2.Vacuum sealing drainage therapy using polyvinyl alcohol hydrated foam material for large soft tissue defects
Chinese Journal of Tissue Engineering Research 2014;(25):4090-4094
BACKGROUND:In various clinical treatments of soft tissue defects, vacuum sealing drainage technology can effectively control wound infection, shorten the treatment time, and accelerate wound healing. OBJECTIVE:To further understand the features and characteristics of hydrated ethanol polyethylene foam vacuum sealing drainage treatment, and compare the treatment effects against soft tissue defects with the conventional dressing change treatment. METHODS:A total of 140 cases of large soft tissue defects were divided randomly into two groups. Observation group received hydrated ethanol polyethylene foam vacuum sealing drainage treatment, while control group was treated by conventional dressing change. The degree of pain relief during treatment, the family satisfaction, the survival rate of first skin-grafting, the time needed before skin-grafting, the hospitalization time, the number of operations, the readmission rates, the complication rate and other clinical effectiveness indicators were compared between the two groups. RESULTS AND CONCLUSION: In the observation group, visual analog scale scores decreased 5.76±0.68, in the control group visual analog scale score decreased 2.85±0.53, with significant differences between the two groups (P < 0.05), and family satisfaction degree of the observation group was higher (P < 0.05). The survival rate of first skin-grafting of the observation group was higher than the control group (P < 0.05), the time needed before skin-grafting, the hospitalization time, the number of operations, the readmission rates, and the complication rate were lower than the control group (P < 0.05). The results showed that, compared with conventional dressing change treatment, hydrated ethanol polyethylene foam vacuum sealing drainage has advantages of light pain, short treatment time, low rate of complications, and high efficacy.

Objective To evaluate the clinical effect and application value of internal fixation of Magerl combined with Brooks technique for atlantoaxial instability. Methods A total of 18 patients with atlantoaxial instability, reducible atlantoaxial dislocation with reduction after traction and irreducible atlantoaxial dislocation with traction reduction after anterior laxation were treated with internal fixation of Magerl combined with Brooks technique using autologous bone grafts. Results The patients were followed up for an average 18 months (6-36 months). Screw was probably cut into the vertebral artery in one case. The guide needle was cut into the pharynx due to incorrectly penetrating the C 1 anterior arch of atlas for 3.5 cm in one case but no early complications such as spinal cord injury and local infection occurred. The spinal cord function improvement was marked in 3 cases, good in 9, mild in 4 but unchanged in 2. No case got worse. There were no loosening or break of the screw and cable. Conclusions Combined fixation of Magerl and Brooks techniques reaches three-point fixation and improves the reduction effect. It is necessary to use the combined fixation with best biomechanical stability for atlantoaxial dislocation patient with reduction or near reduction if the structure of the posterior arch of C 1,2 is intact.

To summarize the clinical results of combined transoral anterior decompression and posterior decompression and internal fixation of irreducible atlantoaxial dislocation with spinal cord compression. 12 cases of irreducible atlantoaxial dislocation with spinal cord compression were operated on with transoral anterior decompression combined with posterior decompression and occipitocervical internal fixation with occipitocervical CD rod or Cervifix. With an average of 20 month follow up, clinical cure rate was evaluated according to Symon and Lavender . Vertebral canal vector diameters in MR were measured. The results showed that the total clinical effective rate was 91.6%, and the remarkable effective rate was 50%. The average improvement rate of vertebral canal decompression was 73.6 %. These results suggest that transoral anterior decompression combined with posterior decompression and internal fixation is more suitable for irreducible atlantoaxial dislocation with spinal cord compression.

Objective To eveluate the result of the use of prosthetic disc nucleus (PDN) for treatment of degenerative disc diseases in the lumbar spine. Methods Twenty-two patients with degenerative disc diseases were treated with PDN replacement after the removal of the degenerated intervertebral disc. Results The patients were followed-up for an average 12 months (4-18 months). Both lumbago and leg pain disappeared in all the 22 patients who resumed their work and normal life one month after the operation. PDN translocation was found in 2 out of 10 patients in the early period, but no PDN translocation was found in the remaining 12 patients in the later period. Conclusion PDN could restore disc height and flexibility after nucleotomy. Artificial nucleus replacement was a good option for the treatment of degenerative lumbar disc disease.
