慢性高原病与血常规和血生化指标的相关性研究

Study on correlation between chronic mountain sickness and blood routine and blood biochemical indexes

目的检测久居高海拔地区人群血常规和血生化指标情况,并探讨其与慢性高原病(CMS)之间的关系,为常驻高原人群健康研究提供参考。方法选取在2880~5400 m海拔生活1个月以上的252例男性受试者为研究对象,对受试者静脉血进行血常规和血生化指标检测,并通过血细胞分析参考区间和临床常用生化检验项目参考区间判断血常规和血生化指标异常情况;应用CMS量表调查CMS患病情况,并比较血常规和血生化指标在CMS患病人群和非患病人群之间的差异;分析血常规及血生化指标与CMS的关系。结果①多项血液指标在常驻高原人群中存在异常,其中红细胞数量、血红蛋白浓度(HGB)、红细胞压积(HCT)、平均血小板体积以及尿酸(UA)水平高于正常参考值上限的人群分别占比71.0%、75.8%、96.4%、82.1%和72.1%;血小板分布宽度低于正常参考值下限的人群占比76.3%。②与非CMS患病人群相比,CMS患病人群的HGB、HCT、总蛋白、甘油三酯(TG)和低密度脂蛋白胆固醇水平显著增高;③与非CMS患病人群相比,CMS患病人群的血小板计量和总胆汁酸水平的异常率显著增高;④嗜酸性粒细胞百分比增加(EOS%)、HGB升高和TG增高是CMS患病的主要危险因素;⑤TG的受试者工作特征曲线(ROC曲线)预测CMS的ROC曲线下的面积(AUC)为0.710。结论EOS%、HGB和TG增高是CMS患病的主要危险因素,其中TG水平增高可用于CMS早期预警,值得重点关注。

Objective To detect the blood routine and blood biochemical indexes of residents in plateau areas,and analyze their association with chronic mountain sickness(CMS),providing a reference for the health research of the plateau population.Methods A total of 252 male subjects living at an altitude of 2880-5400 m for more than one month were selected as the research subjects.The blood routine and blood biochemical indexes were detected,and the abnormal blood routine and blood biochemical indexes were judged by the reference intervals for blood cell analysis and the reference intervals for common clinical biochemistry tests.The CMS scale was used to investigate the prevalence of CMS,and the differences between blood routine and blood biochemical indexes in the CMS patients and non-CMS people were compared.The relationship between blood routine and blood biochemical indexes and CMS was analyzed.Results①Multiple blood indicators were abnormal in the residents in plateau areas,among which the number of red blood cells,hemoglobin concentration(HGB),hematocrit,mean platelet volume and uric acid levels were higher than the upper limit of normal reference values accounted for 71.0%,75.8%,96.4%,82.1%and 72.1%,respectively;the width of platelet distribution was lower than the lower limit of the normal reference value in 76.3%of the population.②The levels of hemoglobin concentration,hematocrit,total protein,triglycerides,and LDL cholesterol in CMS patients were significantly increased.③The abnormal rate of platelet number and total bile acid level in CMS patients was significantly increased.④Eosinophil percentage,hemoglobin concentration,and triglycerides were the main risk factors of CMS.⑤The receiver operating characteristic curve of TG revealed that the AUC of CMS prediction was 0.710.Conclusion EOS%,HGB,and TG were the main risk factors of CMS,and TG level changes could be used for early warning of CMS,which deserved special attention.
