心脏病患者血浆心钠素浓度初探

本文报道了采用放射免疫分析法检测的136例健康人和95例心脏病患者血浆心钠素含量的结果。健康人血浆心钠素含量为460．86±23．68ng／L，男女之间，年龄之间无明显差异。心脏病患者的血浆心钠素浓度均高于健康人，心脏病患者心功能越差，血浆心钠素浓度越高，其中以肺心病组变化最为明显。

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.

经纤维支气管镜治疗支气管胸膜瘘6例

支气管胸膜瘘（BPF）是指肺泡、各级支气管与胸膜腔交通的窦道。2004年以来我们采用经纤维支气管镜注射医用吻合胶（0B胶）加持续胸腔闭式引流或间断残腔冲洗治疗BPF6例，现总结报道如下。     

保康县视觉第一行动评价

目的 评价保康县视觉第一行动复明手术效果。方法 收集1997年11月18日～12月4日，97例113眼手术的初步情况并进行分析。结果 手术总成功率为92．92％，复明病人脱盲率为88．23％，脱残率为38．23％。结论 本次行动使97例山区眼病患在短期内得到治疗，并取得满意效果。6．19％的手术并发症和7．08％的手术无效，需今后注意避免，也说明边远山区防盲工作亟待进一步加强。
