Abstract


Altitude acclimatization plains into the plateau entering higher altitude plateau or plateau, due to the low pressure, low oxygen, and other factors to stimulate the body to produce a series of reversible, non-genetic compensatory adaptive changes in altitude hypoxia environment a better work and life skills. Plateau from the plains of the troops on the plateau environment, degree of acclimatization is an important basis to reflect the health and combat effectiveness of troops, and is also a good the plateau medical support important basis. So far, the plateau forces acclimatization Evaluation study rarely reported. In this study, in accordance with the National Military Standard the altitude acclimatization evaluation and methods \evaluation studies into the plateau soldiers acclimatization status; exploratory detect the highland warrior blood the EPO, SOD, MDA, TRF and H 2 O 2 content and analysis of the variation in altitude acclimatization process and significance; same time, SCL-90 psychological symptom scale dynamic observation of psychological conditions evaluated before and after the soldiers entered the plateau; on the basis of the above work, the point of view of the medical support to promote the plateau forces acclimatization countermeasures and measures. Method: 1. Epidemiological field investigation, a troop of soldiers to conduct on-site investigations, the course of the investigation, the troops did not enter the same year the recruits enrolled plateau recruits set to control, respectively, did not enter the plateau recruits and enter plateau 7 days, 30 days, six months, recruits symptoms of altitude sickness survey measuring maximum oxygen consumption, blood pressure, pulse value, hemoglobin content, and arterial oxygen saturation and collected 5 ml of venous blood, anticoagulant cryopreservation, respectively the thiobarbituric acid Determination of MDA, xanthine oxidase method SOD using chemical colorimetric test determination of H 2 O 2 , using measured by radioimmunoassay TRF and EPO. 7 days after the cluster random sampling method, select the 80 recruits in a plateau forces recruits as subjects for the follow-up study, using the method of the on-site survey, seven days before the 80 new recruits into the plateau into the plateau 30-day time node SCL-90 psychological symptoms survey. The plateau forces acclimatization status evaluation and analysis based on a literature review, expert consulting, research policies and measures to promote the plateau forces acclimatization medical support. Results: 1. According to the National Military Standard \service rate of 52.78%, 63.93% of the basic stages of acclimatization acclimatization was completely acclimatization phase the acclimatization rate of 73.39%. Χ 2 inspection, basic stage of acclimatization and completely acclimatization stage acclimatization rate significantly higher than the initial acclimatization stage (P lt; 0.05), the learning of basic acclimatization stage and completely acclimatization stage service rate no significant difference (P gt; 0.05). The results of the blood biochemical parameters: between the various stages of plasma MDA were significant differences (P lt; 0.05) complete acclimatization stage lower than that of the control, the preliminary stage of acclimatization and basic acclimatization stage is higher than that of the control, preliminary The acclimatization stage than basic acclimatization stage. Plasma SOD activity values ??also between the various stages of a significant difference (P lt; 0.05) complete acclimatization stage lower than that of the control, preliminary acclimatization stage and acclimatization stage is higher than that of the control, basic acclimatization stage at the stage of preliminary acclimatization. Plasma H 2 O 2 content, preliminary acclimatization and basic acclimatization stage are significantly higher than the control (P lt; 0.05) significantly basic acclimatization stage higher than the initial acclimatization stage and completely acclimatization stage (P lt; 0.05), and between the preliminary stage of acclimatization and completely acclimatization stage no statistically significant difference (P gt; 0.05). Initial acclimatization stage and completely acclimatization stage TRF significantly higher than that of the control (P lt; 0.05) basic acclimatization stage TRF significantly lower than the initial acclimatization stage (P lt; 0.05), and the a basic acclimatization stage with control between, the the initial acclimatization completely acclimatization no significant difference (P gt; 0.05). Initial acclimatization phase plasma EPO water average significantly higher than the other stages (P lt; 0.05), to enter a basic acclimatization and complete acclimatization stage to gradually reduce the basic acclimatization stage is still higher than the plasma EPO stationed in front, while completely acclimatization stage plasma EPO levels stationed before no significant difference (P gt; 0.05). Compared with the norm, seven days before entering the plateau of the psychological factor scores in addition to the \Seven days into the plateau, somatization significantly higher than the norm (P lt; 0.05) the anxiety factor elevated to the level of the norm, the rest of the factor scores remained significantly lower than the norm (P lt; 0.05). 30 days to enter the plateau, the anxiety factor scores significantly lower than the norm (P lt; 0.05), and the somatization scores remained significantly higher than the norm (P lt; 0.05). Compared with seven days prior to entering the plateau, seven days into the plateau equalization of positive items, somatization, anxiety, paranoia factor scores significantly increased (P lt; 0.05), interpersonal sensitivity factor, hostile factor scores rise significantly lower (P lt; 0.05). 30 days into the plateau somatization was still significantly higher than the seven days prior to entering the plateau (P lt; 0.01), interpersonal sensitivity factor is still significantly less than 7 days prior to entering the plateau (P lt; 0.05). Into the plateau compared to 7 days, 30 days into the plateau somatization factor, the other factor significantly lower (P lt; 0.05), hostile factor significantly higher (P lt; 0.05). 3 from entering the plateau before entering the way and into the plateau after three stages, from medical aid, protection of drug paraphernalia, and psychological protection and promote acclimatization medical support measures. Conclusion: 1. Studies have shown that the Force acclimatization conditions overall better the acclimatization rate in the initial acclimatization stage basic acclimatization stage and completely acclimatization stage gradually improve With access to the plateau time goes by, the troops overall acclimatization gradually improved. Detect blood indicators consistent trend TRF with EPO and Hb trend oxidative damage indicators MDA, H 2 O 2 and anti-oxidative damage indicators the SOD trend pursuant of altitude acclimatization evaluation method \Stationed plateau in this study. Soldiers of various psychological factors generally lower than the norm or no significant difference compared with the norm, soldiers entered the plateau, except somatization symptoms, psychological status overall better than the norm in the crowd; enter compared before and after the plateau, the soldiers psychological symptoms due to the impact of the plateau environment, increased symptoms of somatization, interpersonal relatively good access to the plateau before the rest did not change significantly. 3. Forces to take a lot more promoting acclimatization medical support measures, but not strong enough targeted acclimatization reason, according to the study found that the forces are not proposed targeted measures so that the troops further acclimatization plateau environment, improve the operations of the armed forces to force .
