Research on Rapid Initial Adaption to the Environment of a Plateau.

We designed two types of pre-adaption plans for this study. One was a pre-adaption training with progressive intermittent hypoxia, with a constant lower pressure oxygen tank used in the plain before arriving at the plateau (PG). The other was by progressively increasing the time of exposure to hypoxia with oxygen supplied in stages after radical plateau (RG).

Analysis on the chaotic characteristics of postganglionic inferior cardiac sympathetic nerve activity.

Taking cats as experiment animal model, the chaotic characteristics of postganglionic inferior cardiac sympathetic nerve activity (PICSNA) is analyzed with Cao method, correlation dimension analysis and largest Lyapunov exponent analysis. The analysis results show that the deterministic chaos lies in the peak-peak interval time series of PICSNA. Our work maybe can help explain why HRV is chaotic.
