海军招飞体检20余年以来一直沿用1996年及2005年颁布的《中国人民解放军招收飞行学员体格检查标准》,随着我国经济的发展和人民生活、文化水平的提高,参加招飞学生的身体素质特征有了明显的变化,此外,航空武器的发展和医学技术的提高也对飞行员的体格标准提出了一些新的要求,为了与时俱进适应新形势的需要,自2010年起海军招飞体检开始试行新颁布的《空军招收飞行学员体格检查标准(试行)》(以下简称标准).为了对新标准试行后的招飞体检工作进行总结,我们回顾了2008-2011年度招飞体检初检的结果并分析如下. 相似文献

Objective To explore the effects of rats adipose-derived stem cell (ASC) on the proliferation and migration of fibroblasts from the tympanic membrane, and to discuss the possibility and significance of therapy with ASC for tympanic membrane (TM) healing and regeneration. Methods Wistar rats were sacrificed, and then the isolation, culture and identification of both ASC and the TM fibroblasts were performed respectively. To verify the effect of ASC on fibroblasts proliferation, transwell coculture system was used. To examine the effect of ASC on fibroblasts migration, cell migration assay with transwell was also applied. All the data were analyzed under a confocal laser scan microscopy system.Results Immunofluorescence of cell surface markers indicated that rats ASC were positive for both of CD44 and CD29, but negative for CD34. The rat TM fibroblasts were positive for vimentin. The fibroblasts cocultured with ASC proliferated faster than the fibroblasts of control group, and the difference of the cell counting number between the two groups was significant ( t = 6. 75, P = 0. 003 ). Compared with the control group, the fibroblasts cultured with ASC conditioned culture medium migrated significantly faster, and the space between the fibroblasts and the polycarbonate membrane pore was significantly shortened at different time point ( 1, 2. 5 and 4 h, P < 0. 05 ). The cell number of the fibroblasts that had migrated through the polycarbonate membrane had been significantly increased 5 h after migration ( P < 0. 05 ). Conclusion ASC might promote TM fibroblasts proliferation and migration by paracrine activation, and it will faciliate the regeneration of TM fibrous layer. 相似文献

海军飞行学员医学选拔五官科淘汰疾病分析 总被引:2,自引:0,他引:2
目的:探讨、总结飞行学员医学选拔中的规律。方法:查阅历年体检淘汰疾病统计表,对各种疾病淘汰率进行比较分析,对位于前几位的疾病的体检方法和可能原因进行分析总结。结果:13年招飞体检耳鼻咽喉及口腔科共检查51421人,淘汰17020人,淘汰率33.10%。淘汰疾病占前几位的是鼓膜菲薄疤痕、鼻中隔偏曲、咬颌畸形、鼻窦炎等。结论:对飞行学员医学选拔中淘汰疾病谱的分析和总结,有利于做好统计工作,改进工作方式方法,提高体检质量,真正做到“合格有把握、淘汰有依据”。 相似文献

患者男性,23岁,现役飞行学员,飞行时间210h,机种为轰五教练机。患者以鼻阻3年,加重伴流涕三月余,于2001年5月8日人院。患者3年前感冒后开始有鼻阻症状,曾在地方医院诊为“慢性鼻炎”,行“激光治疗(术式不详)”后症状好转,但常于飞行或感冒后加重。因患者怕影响飞行训练,故未及时向航医报告,也未采取任何治疗措施。2001 相似文献

姜丹泉 《国外医学:耳鼻咽喉科学分册》2002,(4)
用回顾门诊病历的方法探讨了 32例患有水平半规管发作性位置性眩晕 (HC- PPV)患者的治疗方法。HC- PPV是一个综合症 ,病因可能是从位于内淋巴尾部或水平半规管前支内的囊斑上分离的耳石碎片 ,当病人头位恰巧摆动到病变侧时 ,这些碎片刺激壶腹部 ,产生位置性眩晕和水平眼震。症状包括由仰卧位到侧卧位的头位改变而引起的突发性眩晕 ,潜伏期很短 (几秒钟 ) ,持续时间一般在一分钟以内 ,并有可用头位变动诱导出并加重的水平眼震。本文介绍的治疗方法是建立在 Asprella等提出的一个假设上 ,即认为通过转动病人的头部 ,使游离的耳石碎片移动… 相似文献
