  • Relationship between the expression of biomarkers in the activated innate immune cell and vital organs injuries during the cardiopulmonary bypass

    Although great progress has been achieved in the techniques and materials of cardiopulmonary bypass (CPB), cardiac surgery under CPB is still one of the surgeries with the highest complication rate. The systemic inflammatory response is an important cause of complications, mainly characterized by activation of innate immune cells and platelets, and up-regulation of inflammatory cytokines. After activation, a variety of molecules on the membrane surface are up-regulated or down-regulated, which can amplify tissue inflammatory damage by releasing cytoplasmic protease and reactive oxygen species, and activate multiple inflammatory signaling pathways in the cell, ultimately leading to organ dysfunction. Therefore, the expression of these cell membrane activation markers is not only a marker of cell activation, but also plays an important role in the process of vital organ injury after surgery. Identification of these specific activation markers is of great significance to elucidate the mechanisms related to organ injury and to find new prevention and treatment methods. This article will review the relationship between these activated biomarkers in the innate immune cells and vital organ injuries under CPB.

  • MINIPLATE INTERNAL FIXATION AND AUTOGENOUS ILIAC BONE GRAFT IN SURGICAL TREATMENT OF OLD METATARSAL FRACTURES

    Objective To summarize the experience of treating old metatarsal fractures with surgery methods of miniplate internal fixation and autogenous il iac bone. Methods Between May 2009 and July 2010, 7 patients with old metatarsal fractures were treated surgically, including 5 multi-metatarsal fractures and 2 single metatarsal fractures. There were 5 males and 2 females aged from 25 to 43 years (mean, 33 years). The time from fracture to operation was 4-12 weeks. The X-rayfilms showed that a small amount of callus formed at both broken ends with shortening, angulation, or rotation displacement. The surgical treatments included open reduction, internal fixation by miniplate, and autogenous il iac bone graft (1.5-2.5 cm3). The external plaster fixation was used in all patients for 4 to 6 weeks postoperatively (mean, 5 weeks). Results All incisions healed by first intention. The 7 patients were followed up 8-18 months (mean, 13.5 months). The cl inical fracture heal ing time was 6 to 12 weeks postoperatively (mean, 8.4 weeks). No pain of planta pedis occurred while standing and walking. The American Orthopaedic Foot and Ankle Society (AOFAS) mesopedes and propodium score was 75-96 (mean, 86.4). Conclusion It has the advantages of rel iable internal fixation, high fracture heal ing rate, less compl ications to treat old metatarsal fractures with surgery methods of miniplate internal fixation and autogenous il iac bone graft, so it is an effective treatment method.
