Objective To investigate the clinical effect of proximal femoral nail anti rotation intramedullary nail (PFNA)in the treatment of intertrochanteric osteoporotic fractures in elderly patients.Methods 42 cases of femoral intertrochanteric fracture were treated with proximal femoral nail anti rotation intramedullary nail (PFNA)in cases (AO type,A1 type 13 cases,A2 type 24 cases,type A3 5 cases).Results The group of 42 patients after 12 -36 months of follow -up,the average follow -up time of 18 months,all the patients were healed,1 case of deep venous thrombosis,1 case of mild coxa vara.According to the Harris evaluation standard:excellent 32 cases,good in 9 cases,fair in 1 case,the excellent rate was 97.6%.Conclusion The proximal femoral nail anti rotation (PFNA) anti tensile,anti sliding and anti rotation function is good,and has the advantages of simple operation,small trauma,for osteoporotic intertrochanteric fracture patients can be applied.

OBJECTIVE: To explore the safety and feasibility of endoscopic thyroidectomies through modified chest and mammary areola approach. METHOD: We retrospectively analyzed 122 cases of endoscopic thyroidectomies through a modified chest and mammary areola approach without extensive dissection of thoracic flap. The information about general status, surgical procedures and techniques, complications, etc. were summarized and discussed. RESULT: One hundred and twenty-one cases were operated successfully while 1 case was converted to video-assisted thyroidectomy through infraclavicular approach. The maximum diameter of the mass was (2.05 ± 1.06) cm, mean operation time was (88.61 ± 27.87) min, the operative blood loss was (31.23 ± 16.14) ml, duration of postoperative drainage was (3.54 ± 0.88) d and overall drainage volume was (139.09 ± 95.93) ml. Parathyroid glands were detected in specimens of 9 cases while no case of permanent postoperative hypocalcaemia was displayed. 6 cases of hoarseness were developed. One case experienced conversion surgery, all the others obtained satisfactory cosmetic result. All cases were followed up for 0-24 months without relapse and metastasis of the disease. CONCLUSION Endoscopic thyroidectomy via a modified chest and breast areola approach can facilitated the procedure and avoid extensive dissection of thoracic flap, and proved to be safe and effective.

Objective:To investigate the induction and differentiation potential of ADSCs by tissue culture method,and to preliminary study on the origin of ADSCs.Methods:Using adipose tissue culture method to culture human ADSCs.The third generation of ADSCs for the adipogenic and osteogenesis differentiation,and staining by oil red O and alizarin red S.HE staining was performed after the seventh day culture of adipose tissue.Results:The primary human ADSCs were successfully cultured with adipose tissue culture method.ADSCs cultured to the eighth generation,still maintained a good proliferation ability and cell morphology.ADSCs can be successfully induced into adipose cells and bone cells.ADSCs were mainly distributed around the mesenchymal vascular and connective tissue,by HE staining of adipose tissue after seven days of culture.Conclusion:The cells that were cultured with adipose tissue have the potential to adipogenic and osteogenesis differentiation.The ADSCs were mainly distributed around the mesenchymal vascular and connective tissue.

OBJECTIVE: To explore the safety, effectiveness and feasibility of 3D laparoscopy in thyroidectomy via modified chest and mammary areola approach comparing with 2D. METHOD: Twenty six cases received 3D laparoscopic thyroidectomy (3D group) and 34 cases experienced 2D (2D group). We compared the indexes about general status, operation time, operative blood loss, duration and overall volume of postoperative drainage, complications, etc between two groups. RESULT: Eight cases of thyroid cancer were detected in 3D group and 3 cases in 2D group. While there was no statistical difference between two groups with respect to other observation indexes such as other general status, operation time, operative blood loss, duration and overall volume of postoperative drainage, complications, etc. CONCLUSION 3D laparoscopic thyroidectomy via modified chest and mammary areola approach is a safe, effective and feasible procedure, and it may substitute the place of 2D in the future.
