去细胞喉支架的制备及喉肌细胞再生的可行性研究

Objective To prepare a deeelhilarized whole laryngeal scaffold by utilizing a perfusion-decellularized technique, reseed cells on it, and construct recellularized laryngeal muscles. Methods Perfusion decelluarized larynxes were obtained by common carotid arterious perfusion with detergents. Then they were performed by macroscopic view, histological examination, scanning electron microscopy (SEM) and cartilage viability. Decellularized laryngeal scaffold were then reseeded with inducted mesenchymal stem cells (MSCs). Composites were transferred into greater omentums of rabbits after one day' s adherence and harvested after eight weeks. Macroscopic view, histological examination and immunohistochemistry were performed. Results Perfusion larynxes became transparent after two hours. Histology and SEM indicated that perfnsion method shewed better deculluarized effect. More ventages and collagen fibers but no intact cell or anclei were retained in the decellularized martrix. Porosity measured by Image pro plus 6. 0 was 80. 4% ± 3.2% (x ± s). Chondrocyte vitality assay indicated chondrocyte vitality rate in the perfusion group was 86. 9% ± 1.5% . After eight weeks, vascularization formed and integrated cartilage frameworks still remained. Histological examination could clearly show the presence of muscle bundles and vessels. Immunohistoehemical examination indicated that sarcomeric-α actin expressed positively in corresponding areas. Conclusions It is feasible to reseed MSCs into the decellularized laryngeal muscle matrix for constructing tissue-engineered laryngeal muscles. This in vivo maturation into the omentum could be the first step before in situ implantation of the construct.

降粘化瘀法治疗慢型克山病血液流变学指标的探讨

克山病是以缺血缺氧性心肌坏死为主要特征的地方性心肌病。多年来人们已经注意到在冠心病、心肌梗塞等缺血性心脑血管病发病过程中的血液流变学方面的改变,并且在应用降粘、解聚、溶栓等中药的治疗中取得明显的治疗效果。作者曾对37例克山病患者进行了血液流变学的检测,结果表明:克山病患者的血液呈现高粘滞状态。为了改善这一状态,作者对

防损伤套管在空心钉微创内固定术中的应用

以微创的术式，用空心钉治疗股骨颈骨折已有较多的报道。我院在术中使用一种自制的专利器械，能使同类型手术所致的创伤降低到最小程度，术中出血量减小到最少程度。现将我院1999～2003年治疗的58例情况报道如下。     

高龄食管癌贲门癌的外科治疗

高龄食管癌贲门癌在临床上并非少见，但由于考虑到患者的体质、家庭和社会因素，使不少患者失去最佳手术治疗时机。我院自1993年9月至2003年9月共手术治疗食管癌贲门癌67例，其中70岁以上13例，占19．4％，手术疗效满意，现报道如下。
