[Effects of shengmaiyin and danshen-chuanxiong decoction on preventing cardiopulmonary changes in adults caused by a high-altitude environment].
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 less than 0.05 or P less than 0.01) in the former. Besides the FEV1% and FEF25%, the FVC, FEV1.0, MMF, PEFR, FEF75% and FEF50% were all elevated (P less than 0.05 or P less than 0.01). After the villagers at the altitude of 2500 m area entered the area at the altitude of 4475 m, their LVETI became shorter, PEPI became longer, and PEP/LVET rate was increased (P less than 0.05 or P less than 0.01). Besides FEV1% and PEFR, other values of pulmonary function were increased obviously (P less than 0.05 or P less than 0.01). The Shengmaiyin could efficiently protect the villagers from the plateau reaction described above, while the Danshen-Chuanxiong decoction was not satisfactory.
