目的:调查驻喀喇昆仑山和西藏阿里某部队高原红细胞增多症(HAPC)的患病率。方法:依据我国高原红细胞增多症诊断标准,逐一问诊、体检和血液学检查,但将血红蛋白(Hb)≥210g/L定为高原红细胞增多症的血液学诊断标准。结果:喀喇昆仑山海拔5380m驻防一年官兵HAPC患病率(85.7%)较5100m(48.4%)和4300m(43.5%)增高,(P<0.05和P<0.01);HAPC患者较非HAPC者Hb增高(P<0.001),血氧饱和度(SaO2)降低,(P<0.05)。驻西藏阿里海拔4300m某部队汉族军官和士官HAPC患病率(42.6%)较义务兵(17.9%)增高(P<0.001);HAPC患者的年龄、上高原时间和Hb均较非HAPC者增高,SaO2降低(P<0.001)。藏族官兵无HAPC患者。结论:驻喀喇昆仑山某部队随海拔高度升高,HAPC患病率增高。驻西藏阿里某部队军官和士官HAPC患病率较义务兵高。
Objective: To investigate the prevalence of altitude sickness (HAPC) in a unit of the Karakorum Mountains in Karakorim and Ali, Tibet. Methods: According to the diagnostic criteria of high altitude polycythemia in our country, we asked one by one medical examination, physical examination and hematology examination. However, hematoglobin (Hb) ≥210g / L was defined as the hematological diagnostic criteria of high altitude polycythemia. Results: The prevalence of HAPC among officers and soldiers at the station elevation of 5380m at Karakorum Mountain (85.7%) was higher than that at 5100m (48.4%) and 4300m (43.5%) (P <0.05 and P <0.01) Hb increased (P <0.001), blood oxygen saturation (SaO2) decreased (P <0.05). The prevalence of HAPC among Han nationality officers and sergents at a unit of 4300m in Ali, Tibet (42.6%) was higher than that of volunteers (17.9%) (P <0.001); the age, plateau time and Hb in HAPC patients were higher than those in non-HAPC patients Decreased (P <0.001). Tibetan officers and men without HAPC patients. Conclusion: The prevalence of HAPC increased with the elevation of a certain unit in the Karakorum Mountains. Habitat officers and sergeants in a unit in Ali, Tibet, have a higher prevalence of HAPC than their counterparts.
