飞行人员空晕病的诊治和医学鉴定

Objective To summarize the clinical features,diagnosis and treatment methods,prevention and control measures,and medical evaluation principles for airsickness in flying personnel. Methods Forty-nine cases of flying personnel with airsickness,who were hospitalized from September of 1976 to July of 2009,were retrospectively analyzed in respect of disease course,etiology or incentive,clinical diagnosis and medical evaluation of airsickness.The relationship between vestibular function status and medical evaluation was also statistically analyzed. Results ① Three of 49 picked cases were diagnosed as primary airsickness while the rest 46 were the secondary that were induced by different causes or incentives.Etiological treatment and vestibular habituation were the primarily treatments for such airsickness.② Among these cases,22 were normal in vestibular nystagmus electroretinogram (VNG) comparing to 27 abnormal cases.③ Sixteen and 33 cases were evaluated as normal and deficient Coriolis acceleration tolerance respectively.④ Eleven flying personnel Were finally qualified while 10 and 28 were temporarily and permanently grounded respectively.Flying personnel with abnormal VNG or with deficient Coriolis acceleration tolerance showed higher grounding rate than those with the normal (χ2=5.584,16.722,P<0.05). Conclusions Airsickness in active service flying personnel is mostly the secondary affection,which is caused by various primary disease or incentives.Such prevention and control measures as treating primary disease.eliminating incentives and implementing vestibular habituation are suggested.The effect of airsickness treatment and vestibular function should be emphasized in making medical evaluation.

Objective To summarize the experiences of diagnosis,treatment and medical evaluation of thyroid disease in flying personnel. Methods Sixty-seven cases of thyroid diseases,that were hospitalized from December 2000 to December 2009,were collected and analyzed.They were concluded such categories as:①asymptomatic benign thyroid nodules;②Hashimoto's disease;③diseases of abnormal thyroid functions (including hyperthyroidism and hypothyroidism);and ④thyroid cancer.Their characteristics and the relationship between different categories were analyzed correspondingly to the evaluations for flying. Results ①Among 36 cases of diagnosed asymptomatic benign thyroid nodules (53.73%),4 (3 were adenoma and 1 was nodular goiter) were surgically treated.31 Cases were evaluated as qualified for flying but should be with regular medical check-up while the other 5 were permanently grounded.②There were 5 cases of Hashimoto's disease with normal thyroid functions (7.46%).They were qualified for flying but should be with regular medical check-up.③Thyroid dysfunction took 20 cases (29.85%),among which 18 were hyperthyroidism and 2 were hypothyroidism.Drug treatment was applied.Six cases were finally qualified for flying while the other 3 and 11 were respectively assessed as temporary and permanent grounding.④Six cases were thyroid cancer (8.96%),included 4 papillary carcinoma cases and 2 follicular thyroid carcinoma cases.Only 1 case was finally qualified for flying while the others were permanently grounded.Statistical analysis showed that thyroid dysfunction diseases and thyroid cancer caused significant higher disqualification rate than benign thyroid nodules and Hashimoto's diseases (P<0.01 or P<0.05). Conclusions Benign thyroid nodules are the common thyroid diseases in flying personnel.But the diagnosis of thyroid dysfunction diseases and thyroid malignant tumors should be cared in order to win the chance of treatment and further to reduce the rate of flying disqualification.

Methods PWV and ABI were detected in 107 cases of flying personnel by arteriosclerosis detector and 107 civil personnel were examined as control group. Results 10 cases (9.3%) of abnormal PWV were found in flying personnel group while 36 cases (33.6%) found in control group. Only one abnormal ABI case was in control group but in flying personnel group. The mean PWV of both groups' showed significant increase with the age growing (F= 3. 314-13. 819, P＜0. 05). The mean PWV of flying personnel group was significantly lower than that of the control group in same age segment (t= 2. 187-4. 208,P＜0.05). Linear regression analysis showed that PWV was closely related to the age, blood pressure, waist circumference (WC) and body mass index (BMI) in flying personnel group (β=0. 439-0. 634, P＜0. 05). Conclusions The increases of age, blood pressure and WC or BMI are the major risk factors of causing aorta elasticity decreased in flying personnel. It is suggested that the PWV would be an applicable functional index in early diagnosis of vascular pathological changes and in medical evaluation.

Abstract： Objective To investigate the clinical features by analyzing two flying personnel cases of multiple system atrophy (MSA) for the references to diagnosis, treatment, as well as the influence to flying and the criteria of individual aeromedical evaluation. Methods The clinical data of 2 cases of aircrew with MSA were analyzed and related literatures were reviewed. Results The clinical MSA features of both cases were not typical in their early stage but 1 case appeared typical features in late stage. These 2 cases were misdiagnosed in a certain time because of MSA's rare occurrence, but finally the definite diagnosis was made by judging clinical features, electrophysiology and imageology examinations. These 2 pilots were finally disqualified for flying. Conclusions The clinical features of degeneration diseases of neurologic system in early stage were obscure and had relative longer course of disease, especially for those physical fitness pilots. So it raised higher requirements to the aviation physician in early recognizing the features of MSA for preventing misdiagnosis. Aeromedical assessment of flying personnel with degeneration diseases of neurologic system should be synthetically evaluated according to clinical features, aircraft type and mission.

提高前庭稳定性的简易锻炼方法效果观察

根据电动转椅Coriolis加速度刺激法对半规管系统能产生复合刺激作用的原理,设计了一套提高前庭稳定性的简易锻炼方法。结果表明,Ⅰ组(晕机锻炼组)经锻炼后前庭植物神经反应消失;Ⅱ组(晕机对照组)两次检查的参数无变化;Ⅲ组(正常锻炼组)经锻炼后前庭适应性机能得到进一步巩固。经实际飞行检验,本法具有远期效果。本法无须仪器及锻炼器材,容易掌握,能综合性地提高严重晕机反应的飞行人员及健康飞行人员的前庭系统的适应水平。     

Coriolis加速度刺激适应豚鼠前庭传出系统神经元活性的变化

目的 探索动物前庭适应产生的神经生理基础。方法 采用胃电图波幅值作为观察植神经反应的指标,利用小剂量、多次重复的Ｃｏｒｉｏｌｉｓ加速度刺激,建立前庭适应动物模型。采用免疫组化染色和显微相对灰度分析方法,观察动物在产生前庭适应前后,以及前庭适应消退后,脑干前庭传出系统神经元细胞活性的变化,及其与胃电图波幅值变化的联系。结果 建模成功豚鼠受到运动刺激时,刺激前后的胃电图波幅相近。在前庭适应的豚鼠身上,其脑干前庭传出系统神经元内胆碱乙酰化酶的含量明显增加;但在前庭适应消退后,这种含量的差别消失。这表明在豚鼠出现适应性时此神经元对于前庭终器感觉细胞的抑制性作用明显增强。结论 脑干前庭传出系统神经元可能通过降低前庭终器感觉细胞向中枢神经系统的信号发放的程度,参与了适应性的产生过程。     

晕机病的预测和克服

晕机病的预测即指预测个体对晕机病的易感性。个体对于晕机病的易感性存在着差别，且与种族、性别、个体的机能状态和环境影响等因素有关。通过检查这种差异即可对个体的易感性做出预测。预测方法按其效度大小排序依次是：作业环境中检验（效度r=0．82）、诱发试验（r=0．62）、病史调查（r=0．58）、心理倾向试验（r=0．25=0．51）、适应性检测（r=0．33）和生理倾向检测（r=0．25—O．26）。1990年于立身报告的利用前庭和机动刺激及其相互作用诱发眼震电图的改变来预测晕机病的方法，效度r=0．849。有关晕机病易感性的理论认为：至少有三种内在因素影响着人体对晕机病的易感性，即感受性、适应性和保持性。通过此理论开展的晕机病的克服工作有多个方面。目前主要西方国家空军克服晕机病的工作着眼于对运动环境的适应性训练上。其内容主要包括在地面上训练发生晕机病的飞行员进行放松和自主性控制；继之在地面上对其施加Corion交叉力偶刺激，缓慢加大刺激量，使其能够在早期识别晕机病症状并控制其发展；最后再在实际飞行环境中进行逐步训练，直至完全或部分恢复正常飞行活动。主要使用了入静、意念想象等放松技术，并通过生物反馈方法进行自我控制的训练。这些工作对景机病的克服率达77％-79％。     

28例飞行人员胸外科疾病的诊治及医学鉴定

目的探讨飞行人员胸外科疾病的诊治及医学鉴定原则。方法收集分析我院近20年收治的28例胸外科疾病飞行人员的临床诊治经过及最终医学鉴定结论资料,对不同疾病种类、有无临床症状、飞行结论、机种以及合格飞行人员的随访进行统计分析。结果有50％的患者无临床症状,系在体检过程中胸部X线检查发现。有、无临床症状与疾病的性质及鉴定结论间无相关性。恶性疾病9例,占32．1％,其中肺癌常见;非恶性疾病中,先天性疾病、感染性疾病及原发性气胸常见。28例胸外科疾病飞行人员治疗后飞行合格率较高,为60．7％。合格飞行人员随访至今或最高年限,疾病未再发,空中适应良好。结论飞行人员罹患胸外科疾病相对较少,年度大体检特别是胸部X线片检查对疾病早期诊断有重要价值。肺癌早期经积极治疗,肺功能良好者可恢复飞行。胸外科微创治疗有利于恢复飞行。原发性气胸及肺大泡的医学鉴定应注意复发率的评估。重视肺内孤立结节的鉴别诊断。     

Pharmacological correction of central nervous system function in exposure to Coriolis acceleration

Healthy volunteers with a low vestibular tolerance were exposed to Coriolis acceleration. Potassium orotate, pyracetame and riboxine were used as prophylactic measures against disorders in the function of the vestibular apparatus and higher compartments of the higher nervous system. The central nervous function was assessed with respect to the spectral power of electroencephalograms, short-term memory and mental performance. Potassium orotate given at a dose of 40 mg/kg body weight/day during 12-14 days as well as pyracetame given at a dose of 30 mg/kg body weight/day during 3 or 7 days increased significantly statokinetic tolerance and produced a protective effect on the central nervous function against Coriolis acceleration.
