Objective This study aimed to understand the continuous physiological parameters during sleep under the guidance of Chinese medical theory and clinical practice and to establish the method to diagnose the physical and mental status by analyzing nocturnal sleep data.Methods More than 2000 subjects were recruited in the nocturnal sleep examination using the micro-movement sensitive mattress sleep monitoring system.Based on the analysis of the sleep indices and nocturnal physiological parameters combined with clinical data,a hypothesis was put forward that sleep cycle could reflect the circulation status of qi and blood,as well as some preliminary exploration on revealing the status of qi,blood,yin and yang.Results Sleep structure could reflect the status of qi and blood circulation in different meridians according to the traditional Chinese time unit.Sleep structure and sleep cycle could show corresponding changes if there is morbidity in some meridian,zang-viscera and fu-viscera.Heart rate,respiration rate and other physiological parameters could reflect the alternative predominance of yin and yang.Conclusion Interpreting the physiological parameters during sleep could be a supplementary diagnosis method for Chinese medicine syndrome differentiation.

Objective:To investigate the induction of apoptosis by isoalantolactone in human cervical cancer Hela cells is mediated through ROS generation and Mitochondrial dysfunction. Methods: Cells were treated with isoalantolactone in a dose-dependent manner in the presence or absence of NAC for 24 h as the experimental group,and the normal cells were used as control group. Cell viabilities were determined by the MTT assay;the nuclear morphology of Hela cells were observed under fluorescence microscope using the Hoechst 33258 staining;apoptosiscell cycle and reactive oxygen species ( ROS ) and mitochondrial membrane potential(MMP) were measured by flow cytometry;the protein expression levels of cytochrome C,Bcl-2,Bax and Caspase-3 were detected by Western blot. Results:In the present study,we found that isoalantolactone inhibits growth in a dose-dependent manner in Hela cells. Further studies revealed that Hela cells were treated with 20 and 40 μmol/L isoalantolactone for 24 h,after which we could observe the fragmented nuclei and the increased apoptosis rate. And we also found that isoalantolactone arrested the cell cycle at S phase and increased generation of reactive oxygen species and dissipation of mitochondrial membrane potential (△ψm) in Hela cells. While pretreatment with NAC obviously blocked the apoptotic and inhibition effect of isoalantolactone indicating that induction of apoptosis is ROS-dependent,Western blot study showed that isoalantolactone increased the expression of Bax and cleaved Caspase-3 and decreased the expression of Bcl-2 with concomitant release of cytochrome C from mitochondria into cytosol. Conclusion: Isoalantolactone could inhibit the proliferation and induce the apoptosis of human cervical cancer Hela cells in vitro through mediating ROS generation and Mi-tochondrial dysfunction, the mechanism of which is also accompanied by up-regulation of Bax expression, down-regulation of Bcl-2 expression,activation of Caspase-3 and release of cytochrome C.
