  • Systematic Review of Clinical Evidence: the Efficacy of Stereotactic Aspiration in the Treatment of Cerebral Hemorrhage

    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.

  • RESEARCH PROGRESS OF CELLS AND CELL-TRANSPLANTATION METHODS FOR PERIODONTAL TISSUE ENGINEERING

    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.

  • Research progress of pedicled flaps for defect repair and reconstruction after head and neck tumor resection

    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.
