  • Advances in the treatment of chest wall surgical diseases

    Chest wall surgery used to be a subspecialty of traditional thoracic surgery, which has an ancient history of research and clinical practice. It has gradually become an independent professional field in recent years. With the change of concept and the progress of interdisciplines, we have deepened our understanding of related diseases, and the treatment of chest wall surgical diseases has also acquired new characteristics. This article reviews the progress in the treatment of chest wall surgical diseases including chest wall trauma, chest wall deformity, chest wall tumor, chest wall infection and chest wall defect from the perspective of chest wall surgery.

  • TRANSPOSITIONAL ANASTOMOSIS OF C7 POSTERIOR ROOT AND SPINAL ACCESSORY NERVE TO RECONSTRUCT THE TRAPEZIUS MUSCLE FUNCTION

    Objective To introduce a new approach of neurotization to treatment of the shoulder syndrome after the radical neck dissection by using transpositional anastomosis of C7 posterior root and the spinal accessory nerve to reconstruct the function of trapezius muscle. Methods From March 1999 to February 2001, 10 patients underwent the neurotization during the radical neck dissection. In the operation, the apo-cranial part of spinal accessory nerve was preserved from the trapezius muscle (gt;3.0 cm in length) and anastomosed to C7 posterior root. Objective physical examinations and electromyography were conducted before and after operation.One, 6 and 12 months after operation the trapezius muscle function after the transpositional anastomosis was evaluated. Results One, 6 and 12 months after operation, the recovery rates of each part were as follows: 9.8%, 68.9% and 73.5% in upper part; 4.7%, 73.6% and 69.4% in middle part; and 6.2%, 70.5% and 70.3% in lower part. The range of abduction motion of upper arm in 7 cases (70%) exceeded 90°. The mean maximal abduction angle was more than 95°. Evaluation of the shoulder function showed that myoatrophy was mild and the disability of abduction was classified as grade Ⅱ in 7 cases and grade Ⅲ in 3 cases. Conclusion Transpositional anastomosis of the C7 posterior root to thespinal accessory nerve after radical neck dissection can well reconstruct the function of trapezius muscle. This approach provides a wide indication in comparison with the functional neck dissection without impairment of arm function afterthe cutting of C7.

  • Construction of Lentiviral Vector Containing Murine Vascular Endothelial Growth Factor Gene and Its Expression in NS-1 Murine Myeloma Cell Line

    目的 构建含小鼠血管内皮生长因子(mVEGF)的重组慢病毒表达载体,包装成病毒颗粒后感染NS-1小鼠骨髓瘤细胞株,以便进一步探索VEGF在骨髓瘤病理生理机制中的作用。 方法 聚合酶链反应法扩增mVEGF基因,克隆入含嘌呤霉素抗性的pCDH慢病毒表达载体,构建出表达mVEGF的慢病毒表达载体pCDH-mVEGF;采用磷酸钙法将慢病毒系统三质粒pCDH-mVEGF、psPAX2、pMD2.G共转染293FT细胞包装病毒,分别收集转染后48 h和72 h病毒上清并感染靶细胞NS-1,初次感染72 h后开始采用嘌呤霉素筛选稳定株,筛选2周后采用ELISA法检测稳定株细胞培养上清中mVEGF的表达,建立出稳定高表达mVEGF的NS-1小鼠骨髓瘤细胞株。 结果 成功构建重组慢病毒表达质粒pCDH-mVEGF,并包装成慢病毒颗粒,感染NS-1细胞株后获得靶基因的稳定高表达。 结论 成功构建出含mVEGF的慢病毒表达载体pCDH-mVEGF,慢病毒系统能有效介导目的基因在NS-1小鼠骨髓瘤细胞株中稳定表达,病毒包装成功并能有效感染NS-1细胞,为进一步探索VEGF在骨髓瘤病理生理机制中的作用奠定了基础。

  • BASIC RESEARCH ON THE MECHANISM OF VENOUS REVERSE FLOW IN REVERSE-FLOW ISLAND FLAP

    Objective To investigate the basic mechanism of venous flow in reverseflow island flap. Methods Recent relevant literature on the mechanism of venous reverse flow in reverseflow island flap wereextensively reviewed. Results The mechanism of venous reverse flow was a multifactorial phenomenon. “Communicating and collateral by pass route” and “incompetent valve route” were two theories. Conclusion The two routes of venous reverse flow in reverse-flow island flap coexistand complement each other.

  • The Comparative Analysis of Mechanical Suture and Manual Suture in Surgery of Esophageal Carcinoma

    Objective To evaluate the effect of mechanical suture in surgery of esophageal carcinoma,Methods Five hundred and sixty-eight cases of esophagogastrostomy and esophagojejunostomy for esophageal and cardiac carcinoma were collected in our hospital between January, 1988 and December, 2002. They were devided into two groups according to the methods of anastomoses, the group by stapler and the group with hand. The incidence of postoperative complications in the two groups was compared. Results The time of esophagogastrostomy, the total operating time, and postoperative fasting time of group by stapler were shorter than those of group with hand (Plt;0. 01), and there was no statistically difference in the median hospitalized time after operation for two groups. The anastomotic leakage, anastomotic stricture, anastomotic bleeding , incidence of postoperative complications in respiration and circulation and mortality rate of group by stapler were lowed than those of group with hand (2.1%, 1.4%,0%,2.8% and 0.7% vs.6.8%,4.3%,1.4%,16.5% and 2.9%). There was no statistical difference in the postoperative gastro-esophageal reflux for two groups (P 〉 0.05 ). Conclusion The median time of esophagogastrostomy and the median operating time by stapler are decreased and the incidence of postoperative complications is decreased.
