摘要
海拔4475m 高原健康人较2500m 亚高原健康人心率加快,LVETI 缩短,PEP/LVET 值增大,均有显著性差异;肺功能除FEV 1%、FEF25%外,FVC、FEV1.0、MMF、PEFR、FEF75%、FEF50%等值均显著增大(P<0.05或 P<0.01)。海拔2500m 人群进入4475m 高原后,其心肺功能自身比较,LEVTI 缩短,PEPI 延长,PEP/LVET 值增大(P<0.05或 P<0.01);肺功能除 FEV 1%、PEFR 外,其余各值均显著升高(P<0.05或 P<0.01)。益气养阴中药生脉饮预防高原低氧环境对人体心、肺功能的影响效果满意,而活血化瘀中药丹参川芎合剂的预防作用则不甚理想。
Compared with the cardiopulmonary function of the healthy adults on the plateau at an altitude of 4475 m and of 2500 m,the HR was faster,LVET was shorter,PEP/LVET rate was larger(P< 0.05 or P<0.01)in the former.Besides the FEV1% and FEF25%,the FVC,FEV1.0,MMF,PEFR, FEF75% and FEF50% were all elevated(P<0.05 or P<0.01).After the villagers at the altitude of 2500 m area entered the area at the altitude on 4475 m,their LVETI became shorter,PEPI became longer,and PEP/LVET rate was increased(P<0.05 or P<0.01).Besides FEV1% and PEFR,other values of pulmonary function were increased obviousty(P<0.0(?) P<0.01).The Shengmaiyin could efficiently protect the villagers from the plateau reaction describea above,while the Danshen- Chuanxiong decoction was not satisfactory.
