ABSTRACT
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.

ABSTRACT
<p><b>OBJECTIVE</b>To assess the association between brain-derived neurotrophic factor (BDNF) gene Val66Met polymorphism and clinical characteristics of first episode schizophrenia in a Chinese Han population.</p><p><b>METHODS</b>Genotyping of BDNF Val66Met polymorphism was carried out for 135 schizophrenic patients and 483 healthy controls with TaqMan probe technology. The patients' psychotic symptoms were assessed using the positive and negative syndrome scale (PANSS).</p><p><b>RESULTS</b>A significant difference was found in genotype distribution and allelic frequency of the Val66Met polymorphism between the two groups (P< 0.01). In patients, Met homozygotes had a significantly higher score in anxiety/depression factor, cognitive factor and total score of PANSS than Val carriers.</p><p><b>CONCLUSION</b>BDNF gene Val66Met polymorphism is associated with the pathogenesis of schizophrenia. The Met/Met genotype of BDNF Val66Met variant may be a risk factor for symptoms in first episode schizophrenia patients.</p>
