复合低聚肽粉对极地科考队员穿越西风带过程中晕船程度影响的观察

Effect of composite oligopeptide powder on the degree of seasickness of polar scientific expedition team members when crossing the westerlies

目的探讨口服复合低聚肽粉对乘坐雪龙号极地科考船的科考队员在穿越南半球西风带过程中晕船程度的影响。方法选取乘坐第38次雪龙号科考船的队员共30名,分为试验组和对照组,每组15人。观察连续服用5 d复合低聚肽粉(试验组)和蛋白粉(对照组)后对科考队员晕船程度的影响。结果试验组和对照组各收回12份合格问卷,进入西风带第1天50%以上的科考队员达到晕船程度,2组之间的晕船原始分和晕船等级差异无统计学意义(P>0.05)。在服用复合低聚肽粉5 d后,试验组晕船症状原始分由进入西风带第1天的(28.3±6.32)分降为(13.5±4.21)分,晕船等级也明显降低(P<0.05);对照组服用5 d等量蛋白粉后,晕船症状原始分和等级虽也有所下降,但差异无统计学意义(P>0.05)。结论雪龙号科考队员在乘雪龙号科考船进入西风带后大部分出现明显的晕船症状,连续5 d给予复合低聚肽粉干预后,晕船程度明显减轻,表明低聚肽粉具有一定的缓解晕船症状的作用。

Objective To explore the effect of oral composite oligopeptide powder on the degree of seasickness of scientific expedition team members on the Chinese polar research vessel Xue Long when crossing the westerlies of the Southern Hemisphere.Methods A total of 30 team members aboard the polar research vessel Xue Long for the 38th expedition were selected and divided into study group and control group,with 15 in each.Observe the effect of orally intake of composite oligopeptide powder and protein powder for five consecutive days on the degree of seasickness among the scientific expedition team members.Results A total of 12 valid questionnaires were collected from the study group and the control group.On the first day of entering the westerlies,more than 50%of the team members reached the degree of seasickness.There was no significant difference in the original score and level of seasickness symptoms between the two groups.After taking composite oligopeptide powder for five days,the original score of seasickness symptoms in the study group decreased from(28.3±6.32)points on the first day of entering the westerlies to(13.5±4.21)points,and the level of seasickness also significantly decreased(P<0.05);after taking an equal amount of protein powder for five days,the original score and level of seasickness symptoms in the control group also decreased,but the change was no statistically significant difference(P>0.05).Conclusion Most of the scientific expedition team members on the polar research vessel Xue Long experienced obvious seasickness symptoms when entering westerlies.After five consecutive days of intervention with composite oligopeptide powder,the degree of seasickness was significantly reduced,indicating that oligopeptide powder has a certain effect on alleviating seasickness symptoms.
