Combined treatment with areola approach for capsular contracture after breast augmentation with implants / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the combined treatment with areola approach for capsular contracture after breast augmentation with implants.</p><p><b>METHODS</b>From Feb. 2005 to Jun. 2011, 94 cases (168 sides) with Baker III and IV capsular contracture after breast augmentation with implants were treated with areola approach. The implants cavity was recreated, with or without removal of capsule. The implants were reimplanted behind pectoralis major or breast at the second stage in some patients.</p><p><b>RESULTS</b>46 cases were followed up by clinic visit and the others were followed up by telephone for 6-37 months, with an average of 9.9 months. The capsular contracture was relapsed in 2 cases as Baker III and 1 case as Baker IV. All the other breasts got a good appearance with good soft texture and feeling. No hematoma, infection, implants rupture, breast ptosis or implant displacement happened.</p><p><b>CONCLUSIONS</b>Combined treatment with areola approach has a good therapeutic effect for capsular contracture after breast augmentation with implants. The breast appearance is satisfactory with low occurrence of capsular contracture.</p>

The telomerase activity of human adipose derived stem cells during proliferation and differentiation in vitro / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the telomerase activity of human adipose derived stem cells (ADSCs) during proliferation and differentiation in vitro.</p><p><b>METHODS</b>ADSCs were highly purified and cultured in vitro. The morphology, phenotype and biological properties of the cultured ADSCs were observed by flow cytometer. Then ADSCs were induced to differentiate into adipocytes and osteoblast. The telomerase activity was detected by TRAP.</p><p><b>RESULTS</b>ADSCs had the ability of multi-directed differentiation, like adipocytes and osteoblast. It could also express the stem cell-related surface markers. The telomerase activity was negative or lowly expressed in ADSCs in vitro within 12 generations. The telomerase activity was up-regulated when ADSCs was adipogenic differentiated, but deceased 3-6 days later.</p><p><b>CONCLUSIONS</b>The telomerase activity of ADSCs is not changed during culture in vitro. It is up-regulated when ADSCs are induced to adipogenic differentiation, but decreased later.</p>

Interventional radiologic therapy for arteriovenous malformations in the face / 中华整形外科杂志

<p><b>OBJECTIVE</b>To introduce the technique of transarterial interventional embolization treating for arteriovenous malformations (AVM) in the face.</p><p><b>METHODS</b>From April 1998, 17 patients have been treated with this method. Seldinger's maneuver was used in this series. Of them, 11 cases received only interventional embolization; 6 cases received both interventional embolization and surgical resection.</p><p><b>RESULTS</b>The interventional embolization was effective in all the 17 cases, which was confirmed by immediate angiography. Their clinical symptoms were gradually relieved. Interventional embolization obviously decreased hemorrhage during surgical resection.</p><p><b>CONCLUSIONS</b>Interventional embolization provides a new way for the treatment of AVM. Preoperative embolization can lower the surgical risk as it obviously decreases hemorrhage during the surgical procedure.</p>
