航校空军学员飞行前肠道菌群的初步研究

Preliminary study on intestinal flora of air force school students before flight

目的探讨多种因素对航校空军学员肠道菌群的影响。方法通过微生态学方法对150,名航校空军学员飞行前的肠道菌群中的9种细菌进行定性定量分析,并与30名地勤人员进行对比研究,结合多种因素的填表调查分析各种因素对航校学员肠道菌群的影响。结果航校空军学员组双歧杆菌、乳杆菌和消化球菌与地勤组相比有所下降,肠杆菌、肠球菌、拟杆菌、葡萄球菌、韦荣氏球菌、真杆菌数量有所上升,但仅消化球菌差异有统计学意义(P<0.05),其它菌差异无统计学意义(P>0.05)。结论饮食是造成空军飞行员肠道菌群变化的主要原因之一。

Objective To explore the various factors on influence the intestinal flora of air force school students.Method 9 kinds of intestinal flora in 150 air force school students proceed qualitative and quantitative analysis with microecology method before flight,then compared with 30 ground staffs.Combined fill in forms to analysis various kinds factors on influence intestinal flora in students.Results Bifidobacterium,Lactobacillus and Peptococcus were decreased compared to ground staffs.On the other hand,Enterobacter,Enterococcus,Bacteroides,Staphylococcus,Veillonella,Eubacterium were increased,but only Peptococcus had significant difference（P 0.05）,other bacterium were not（P 0.05）.Conclusions Diet was one of the main causes of intestinal flora changes in air force pilots.
