Objective To summarize the current status of pedicled flaps for defect repair and reconstruction after head and neck tumor resection, and to present its application prospects. Methods Related literature was reviewed, and the role evolution of pedicled flaps in the reconstruction of head and neck defects were discussed. The advance, anatomical basis, indications, advantages, disadvantages, and modification of several frequently used pedicled flaps were summarized. Results The evolution of pedicled flaps application showed a resurgence trend in recent years. Some new pedicled flaps, e.g., submental artery island flap, supraclavicular artery island flap, submandibular gland flap, and facial artery musculomucosal flap, can acquire equivalent or even superior outcome to free flaps in certain cases. Technological modification of some traditional pedicled flaps, e.g., nasolabial flap, pectoralis major myocutaneous flap, latissimus dorsi musculocutaneous flap, temporalis myofascial flap, and temporoparietal fascial flap, can further broaden their indications. These traditional flaps still occupy an irreplaceable role, especially in patients with poor condition and institution with immature microsurgical techniques. Conclusion The pedicled flaps still plays an important role in head and neck reconstruction after tumor resection. In certain cases, they demonstrate some advantages over free flaps, e.g., more convenient harvest, more rapid recovery, less expenditure, and better functional and aesthetic effect.

Methods Twenty-two of 365 aneurysm patients who had undergone endovascular treatment between March 2007 and January 2010 in our hospital had perioperative complications. We retrospectively analyzed their clinical data. Results Twenty-two patients had perioperative complications, accounting for about 6%. The aneurysm was ruptured in 6 cases, which occurred before surgery in 2 patients, during the surgery in 3, and after the surgery in 1. There were 10 cases of cerebrovascular spasm, 4 cases of cerebrovascular thrombosis, and 2 cases of puncture site hematoma. Conclusion During the perioperative period of endovascular treatment for intracranial aneurysms, prognostic prevention measures, observation of the occurrence of major complications and proper management of complications can effectively reduce mortality and the degree of disability.
Objective To explore whether there is enough clinical evidence to confirm that stereotactic aspiration does more good than harm in patients with cerebral hemorrhage. Method A systematic review of all relevant clinical studies on stereotactic aspiration in the treatment of cerebral hemorrhage. Results Eight randomized controlled trials (RCTs) including 757 patients and 17 nonrandomized controlled studies including 1 766 patients, as well as 20 uncontrolled studies including 1 244 patients were identified . All studies reported positive results regarding the effects. However, the quality of the included studies were generally poor. The main problem was that most trials reported them as a RCT, but no description of the method of randomization. Conclusions Stereotactic aspiration in the treatment of cerebral hemorrhage is promising based on present evidence. However, at present, we can not draw definite conclusion whether the treatment does more good than harm compared with noninvasive medical treatment because of the poor quality of included studies. Therefore, more high quality RCTs are required.
Objective To summarize the research progress in the diagnosis and treatment of pancreatic cystic neoplasms (PCNs). Method The guidelines and literatures related to the diagnosis and treatment of PCNs were collected and reviewed. Results At present, there was still no clear method to distinguish the types of PCNs and their benign and malignant, and there was still a dispute between domestic and foreign guidelines on the diagnosis and treatment of PCNs. Conclusion Clinical researchers still need to carry out more research, provide higher quality evidence, resolve the disputes existing in different guidelines, standardize the diagnosis and treatment process of PCNs, thus, PCNs can be identified early, diagnosed accurately and intervened in time.
目的 評價國產吻合器和閉合器在食管癌消化道重建術中的應用價值。 方法 回顧性分析2005年3月-2008年4月期間收治的387例食管癌手術患者的臨床資料,根據不同消化道重建方式分為手工吻合組(n=172)和器械吻合組(n=215),對兩組患者吻合時間、術中出血量及術后并發癥發生情況進行對比分析。 結果 全組無手術死亡。器械吻合組和手工吻合組術中出血量的差別無統計學意義(Pgt;0.05),但前者的吻合時間、住院時間均少于后者(Plt;0.05)。手工吻合組術后吻合口出血多于器械吻合組(5.2%比1.4%,Plt;0.05),發生吻合口漏亦多于器械吻合組(6.4%比2.8%,Plt;0.05)。隨訪1.5~2年,排除失訪患者后,器械吻合組吻合口狹窄發生率低于手工吻合組(4.6%比10.3%,Plt;0.05)。 結論 國產吻合器與和縫合器用于食管癌的消化道重建安全有效,值得在基層醫院推廣應用。
Objective To introduce the cells and cell-transplantation methods for periodontal tissue engineering. Methods Recent l iterature about appl ication of cell-based therapy in periodontal tissue engineering was extensively reviewed, the cells and cell-transplantation methods were investigated. Results Mesenchymal stem cells were important cell resourcesfor periodontal tissue engineering, among which peridontal l igament stem cells were preferred. Bone marrow mesenchymal stem cells had several disadvantages in cl inical appl ication, and adipose-derived stem cells might be a promising alternative; different transplantation methods could all promote periodontal regeneration to some extent. Single-cell suspension injection could only promote a l ittle gingival regeneration, and tissue engineered scaffolds still needed some improvement to be used in periodontal regeneration, while cell sheet technique, with great cell loading abil ity and no need of scaffolds, could promote regeneration of cementum, periodontal l igament, and alveolar bone under different conditions. Conclusion Multipotent stem cells are fit to be used in periodontal tissue engineering; improvement of cell-transplantation methods will further promote periodontal regeneration.
