Objective: To investigate the effect of cervical eccentric training on neck function of college students, and to provide basis for cervical spondylosis prevention. Methods: Fifty two students from a medical college in Shanxi Province were recruited. Participants were divided into the neck eccentric training intervention group and the control group according to the random number table method, after stratified by sex. The intervention group received training for 25 min each time, 3 times a week for 6 weeks, and the control group received neck health education. Neck circumference, strength, range of motion, endurance and head and neck posture were measured before and after intervention. Results: The interaction of strength anterior flexion, extension left fiexion and right flexion was significant( F=34.25, 55.96, 56.49, 37.13, P <0.05). After 6 weeks, the strength of the intervention group was anterior flexion(65.37±18.64)N, extension(87.61±21.38)N, left flexion(55.80±12.04)N, right flexion(55.87±11.83)N. After 6 weeks, the strength of the control group were (45.69±9.25), (53.34±9.45), (41.60±6.96) and(42.20±9.92)N, which were significantly lower compared to the intervention group( t =4.82, 7.48, 5.21, 4.52, P <0.01). The interaction of motion of anterior flexion, extension, left flexion and right flexion were significant( F=11.62, 8.83, 8.29, 6.57, P <0.05). After 6 weeks, the motion of intervention group had anterior flexion(53.54±7.28)°, extension(57.42±7.37)°, left flexion(40.77±4.14)°, right flexion(85.12± 6.35 )°. The corresponding motion levels of the control group were(45.35±9.55)°,(50.85±7.56)°,(37.19±5.86)°,(76.15±7.86)°. The intervention group was significantly higher than the control group( t=3.48, 3.18, 2.54, 4.52, P <0.05). Main effects on time were observed in neck circumference, right flexion and left rotation motion, neck endurance and head extension angle( F =15.79, 13.94, 35.90, 10.17, 8.61, P <0.05). Conclusion Six week neck eccentric training can significantly improve neck strength and range of motion, as well as neck circumference, neck endurance and head forward posture.

Objective To observe the physical development indexes of students from a teenager aviation school and to find out about the trainees′characteristics of physical development in order to advise on medical selection of teenager flying cadets and improve the present training programs .Methods Four hundred and thirty six students Grade 2015 were selected as subjects .The data of their physical examinations between school selection examination and annual examination were compared via matched-pair design.Physical growth and development of students in the aviation school were analyzed . Results The height, relative body mass and body mass index (IBM) of the students changed significantly (P<0.05) after one-year training in the youth aviation school .The proportion of students whose body mass accounted for 85% to 120%of standard weight was increased from 84.40%to 93.12%.94.74%of the increase came from students who used to be underweight .The qualified rate of students who reached the 70%-79% of the standard relative body mass in school selection examination was 57.14%.The reached qualified rate of students who reached the 80%-84% of the standard relative body mass in school selection examination was as high as 95.65%.The average height growth of the students was about 2.0 cm in the previous year .Conclusion The relative body mass of students who reached the 70%-85% of the standard relative body mass in school selection examination improved obviously ,suggesting that we should revise the weight standard to less than 30% of the standard weight , which conforms to the objective law of growth and development of adolescents .The rate of development of adolescent height requires further follow-up observation .All the students of a teenager aviation school should pay attention to a reasonable diet , take more physical exercise and monitor body mass .

Objective To compare the physical examination results of nephroptosis in the second stage and the final stage, to find the underlying reasons, and to explore better ways to detect nephroptosis.Methods A total of 1334 subjects participated in both the second stage and final stage of PLA air force medical selection of flying cadets, and physical examination results of both stages were compared.Results All the subjects recruited denied a history of abdominal pain or recurrent urinary tract infection, and urine tests were normal.The positive rate of nephroptosis in the second stage was 10.2%, compared to 5.5% in the final stage.The difference of physical examination results in the two stages was significant, and so was that of disqualification rates.Conclusion Results of physical examination of nephroptosis in the second stage are different from those in the final stage.It′s necessary to find better ways of detection of nephroptosis.

Objective To analyze the data on hearing of recruited students from a teenager aviation school according to both the standards of PLA and those of the US Armed Forces , to learn about their differences in hearing standards in medi-cal selection, and to raise suggestions on establishing hearing standards for medical selection of flying cadets from teenager aviation schools .Methods The data collected on the first hearing test about hearing of students from Hebei Teenager Aviation School were collected .The validity of the data was determined according to the medical selection standards both of PLA and of the US Armed Forces respectively .The cases of qualified or unqualified recruits at high frequency and middle -low frequency were counted respectively and analyzed statistically .Results The unqualified recruits determined by PLA′s standards tended to be unqualified too when determined by the US Armed Forces standards .During the screening of high frequency hearing and the general hearing condition , the proportion of unqualified cases determined by the US selection standards was higher than that determined by PLA′s selection standard .In the screening of middle-low frequency hearing , no statistically significant difference was found in the proportion of unqualified cases when the two different selection standards were used.Conclusion The hearing standard for medical selection of flying cadets at high frequency in the US Armed Forces is stricter than that in the PLA .Meanwhile, the hearing standard at middle-low frequency in the US Armed Forces is different from that in the PLA , though there are no statistically significant differences in the proportion of unqualified cases.The hearing standards of the US Armed Forces are recommended in recruiting flying cadets for teenager flying schools .

Objective To analyze the results of the final aviation medical examination of 1281 students recruited into Air Force youth aviation schools in Hunan and Hubei provinces in order to provide reference for establishing the items and standards of medical selection .Methods The data of 1281 students who participated in final aviation medical examination of Air Force youth aviation schools in 2016 were collected , who came from 28 cities in the above two provinces .The disqualification rate and related unqualified medical items were calculated , and the differences of the disqualification rate and medical geographical areas in the 28 cities were analyzed .Results According to the disqualification rate , the top five departments were ophthalmology , otolaryngology, surgery, radiology and ultrasonic departments .The top 10 unqualified items were the lack of distant vision , fundus diseases , nasal anomaly , ametropia and strabismus , spine abnormality , audition abnormality, vestibular function badness , vitreous opacity, and lens abnormalities.There was no significant difference between the 28 cities in the disqualification rate (P >0.05) or between the two provinces (P >0.05). Conclusion The results of the final aviation medical examination reflect the quality and efficiency of the initial aviation medical examination .To improve the quality of medical selection , further research is needed to set a scientific standard for the initial aviation medical examination while strengthening the scientific protection and intervention of distant vision .The efficiency of selection depends on improving the accuracy of initial aviation medical examination in nasal cavity structure, body shape ,and lens opacity .With a better understanding of the disqualification rate and abnormal items in different cities , a scientific arrangement of professional staff and technical force can make the initial aviation medical examination better, thus effectively reducing the rate of false elimination rate and misdiagnosis .

Objective To analyze the disease spectrum of abdominal external hernia during medical selection of flying cadets and compare the medical standards between US Air Force and Chinese PLA Air Force in order to improve the system of medical selection.Methods The data about abdominal external hernia among flying cadets during Chinese PLAAF medical selection between 2012 and 2015 were retrospectively analyzed and compared with the medical standards of the USAF flying cadets.Results Twenty-nine candidates were eliminated because of hernia,including 4 cases of hiatal hernia,3 cases of umbilical hernia and 22 cases of inguinal hernia.4.70% of the candidates were eliminated because of hernia disease.Empirical research showed difference in hernia standards between China and the USA.Conclusion Compared with Chinese medical selection standards,the USAF standards give more weight to whether the symptoms of disease impact air safety and efficiency.Our medical selection standards need to be improved by learning from foreign practices.

Objective To analyze the change in qualification rate of comprehensive assessment , and to provide an effective theoretical basis for future selection and recruitment of military flying cadets .Methods Group A consisted of 400 cadets who were randomly chosen from the final selection with the physical examination conclusions of disqualifiedandqualified by comprehensive assessmentin a certain year via the cross-sectional investigation method , and group B was composed of 400 cadets who were chosen from the following year with the same method as group A .A questionnaire con-cerning demographic features was conducted among all cadets .A database was established with Epidata 3.02 software, and SPSS 16.0 software was used to analyze diseases which were qualified by comprehensive assessment.Results The qualification rate of comprehensive assessment in group A was higher than group B (45.00%vs 34.75%, P<0.01),there were differences between the two groups in overweight ( underweight ) ,deflection of nasal septum , gallbladder polyp , spinal malformation and undertall(P<0.05 or P<0.01).Conclusion The expert consensus which is made by the air force ex-perts through their work experience and the foreign air force standards has a positive application effect in the practical work . It is an efficient supplement to the physical examination standards and has an important effect on military aviator selection .
