对湖北省1993～2003年采供血机构血液质量实施抽检工作的评价分析

本文通过介绍湖北省对采供血机构血液质量实施抽样监测工作的具体要求和方法，并对1993—2003年抽样监测结果进行了详细统计分析，着重讨论了丙氨酸氨基转移酶、HBsAg、抗-HCV、抗-HIV、RPR五项监测指标出现漏检的原因，并提出了相应的保证措施；同时，对湖北省自2000年以来，血液质量抽样监测未发现传染病方面的异常现象提出了自己独到的见解；另外，亦对血站系统血液质量较中心血库、单采血浆站好进行了三个方面(质量意识、管理模式、仪器设备更新及试剂使用)的原因分析，使读者逐步认识到湖北省自1993年起开展这项工作的重要性和必要性，特别是在加强血液质量管理，保证临床和血液制品生产单位的用血质量，控制血源性疾病的传播所发挥的作用及今后在这项工作上还应急需解决的问题。     

病人跌倒的预防

病人跌倒的预防江苏省吴江市盛泽医院２１５２２８惠康明在医院病区内屡见病人跌例，常以日落黄昏后跌倒的病人开始增多，其中半数以上发生在深夜护士交接班期间，尤其是老年病人，从深夜１１时半至次日７时半，在上厕所或洗漱时最容易发生跌倒。例如：某病人起床去厕所内...     

学校和幼儿园食堂规范化管理的实验研究

本实验主要是探索学校卫生进行综合执法问题。对学校、幼儿园食堂规范化管理的实验为探索学校卫生综合执法提供了可行性依据。本实验结果表明，实验后学校和幼儿园食堂的管理指标（包括设施及设备改进、消毒、生熟分开、防蝇防尘防鼠、个人卫生、环境卫生及卫生管理等）均有大幅度上升，并取得良好的社会效益和经济效益。     

小儿抽动症行为治疗的近期疗效

５１例抽动症的儿童，２６例用行为治疗，包括松予疗法、厌恶性法和药物苯海拉明；２５例用药物治疗，氟哌啶醇和安坦。随访２个月。经统计，２种治疗方法的近期疗效无显著差别，但行为治疗尤对因精神因素和焦虑和紧张而诱发的抽动颤为有效。此外，本文还讨论了行为治疗的机理。

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.
