空中交通的飞行冲突问题日益严重,笔者认为对空中飞行碰撞风险问题研究非常必要,旨在建立进近程序间隔评估模型。通过对影响进近间隔因素的分析确定了各因素对进近间隔的影响程度。应用假设平移法证明了导航台(VOR/NDB)顶空盲区内飞机报告过台位置偏离顶空盲区中心的距离与该距离下报告的飞机数量服从正态分布。应用概率等数学方法计算求得各因素决定的间隔,由各因素间的相互关系确定了模型间隔如何满足各因素确定的间隔。建立了进近间隔评估模型并对模型进行了验证和推广。

目的利用分子生物学及免疫组化方法研究软骨调节素（ChM—I）在成人退变椎间盘细胞及椎间盘组织中的表达情况。方法2009年3月至4月取3例因腰椎间盘退变性疾病而需行后路椎间融合患者的椎间盘组织分别进行髓核及纤维环细胞培养。取部分原代细胞利用RT—PCR和Westernblot研究ChM—ImRNA和蛋白在成人退变椎间盘细胞中的表达情况。利用real—timePCR和Westernblot研究不同浓度碱性成纤维细胞生长因子（bFGF）对髓核细胞和纤维环细胞ChM—ImRNA和蛋白表达的影响。收集2008年10月至2009年10月因腰椎间盘退变性疾病而行手术切除的椎间盘组织标本26例，根据MRI表现退变程度为Ⅲ～V级，作为退变组。收集同期因脊柱肿瘤行手术治疗时切除的椎间盘标本6例，退变程度I级，作为对照组。利用免疫组化方法研究ChM—I在不同退变程度椎间盘组织中的表达情况。结果RT—PCR、Westernblot显示ChM—I在椎间盘髓核细胞及纤维环细胞中均有表达。bFGF可抑制ChM．I在髓核及纤维环细胞中的表达，且呈剂量依赖性（P〈0．05）。ChM-I在对照组椎间盘组织中表达量很低，阳性细胞率为0．12±0．03，而在椎间盘发生退变后其表达量明显升高，退变组与对照组相比差异有统计学意义（P〈0．05）。结论髓核细胞及纤维环细胞可表达ChM-I，bFGF可明显抑制ChM—ImRNA及蛋白的表达。椎间盘发生退变后ChM—I表达明显升高，提示其可能在椎间盘退变的病理过程中发挥一定的作用。
