Résumé
Objective To develop a new type of individual first aid kit for plateau conditions to treat acute high altitude reaction.Methods The theories of military preventive medicine as well as the practices of plateau medical protection and treatment were involved in the design and manufacturing of the kit with emphases on kit body architecture design and selection of equipped medicinal materials.Totally 2 100 servicemen had 1 000 ones divided into a control group and 1 100 ones into an observation group.The two groups both underwent conventional treatment,while the observation group applied the kit besides.The incidence rates and curative effects of acute high altitude reaction were compared in the two groups.Results The kit improved first aid of acute high altitude reaction in time consumed and speed.One week after entering the plateau the scores of headache,gastrointestinal symptom,fatigue and dizziness were (1.5±0.5),(1.7±0.4),(1.3±0.6) and (1.6±0.7) respectively in the observation group,and (2.3±0.6),(2.4±0.5),(2.2±0.5) and (2.4±0.6) respectively in the control group.One month after entering the plateau,the observation group had the recovery rate being 99.2％ and the mean therapy time being (8.1±3.3)d,and the control group had the recovery rate being 91.2％ and the mean therapy time being (15.2±6.4)d.The observation group behaved better than the control group in disease grading,therapy time,recovery rate significantly (P＜0.05).Conclusion The kit gains advantages in convenience,portability and curative effect when used to treat acute high altitude reaction,and thus is worthy promoting practically.

Résumé
Objective To investigate the incidence of altitude reaction among people who rapidly ascend to highaltitude and the health status of experimental emergency blood donors after ascending to high -altitude areas above 4600meters.Methods The vital signs of 185 subjects were analyzed according to GJB1098-1991 and questionaires were filledout.Then the incidence of altitude reaction in different -altitude areas and the change in health status before and after blooddonation at high-altitude were evaluated.Results There was no significant difference in the incidence of altitude reactionin areas of different altitude.However, the incidence of moderate and severe altitude stress increased significantly .Thesimilar altitude reaction incidence despire different means of transportation (74.40% by railway and 70.00% by air) suggestedthat the mode of transportation had little effect.And our results showed good health status among emergency blood donorsbefore and after donation.Conclusion Emergency blood collection is feasible at high altitude (more than 4600 meter high).
Résumé
Local low oxygen pressure caused by low air pressure in the altiplano results in many physiological and neuropsychological problems. For people moving from low-altitude regions to the altiplano, monitoring and improving indoor air quality, enriching its oxygen content are effective measures to ameliorate sleeping quality, psychosis, work efficiency and general health. Ergonomics has a brilliant prospect in enriching oxygen content of indoor air in the altiplano.
