The transition from the systemic inflammatory response syndrome to seere sepsis and septic shock inoles a myriad of pathogenic changes, including circulatory abnormalities that result in global tissue hypoxia.1,2 These pathogenic changes hae been the therapeutic target of preious outcome studies.12 Although this transition occurs oer time, both out of the hospital and in the hospital, in outcome studies interentions hae usually been initiated after admission to the intensie care unit.12 In studies of goal-directed hemodynamic optimization, in particular, there was no benefit in terms of outcome with respect to normal and supranormal hemodynamic end points, as well as those guided by mixed enous oxygen saturation.9,13 In contrast, een though we enrolled patients with lower central enous oxygen saturation and lower central enous pressure than those studied by Gattinoni et al.9 and with a higher lactate concentration than those studied by Hayes et al.,13 we found significant benefits with respect to outcome when goal-directed therapy was applied at an earlier stage of disease.

从全身炎症反应综合征转为严重脓毒症和脓毒性休克牵涉大量发病的变化，包括导致全身性缺氧的循环紊乱。这些发病的变化成为先前结果研究的治疗学目标。尽管这些转变随着时间的流失而逐渐出现，既可以在院外，也可在院内，在结果研究中，干预措施往往在进入ICU之后才启动。特别的，在那些目标导向血流动力学最优化研究中，依照结果，那些以正常或超正常血流动力学为终点的措施未能显示出益处，以混合静脉血氧饱和度为导向的研究同样如此。

This happens in a so called reaction center inPhotosystemⅡ, where a tetrameric chlorophylls (P680) absorb the solar light andinitiate photoinduced electron transfer reaction to the acceptors, quinone A and B. Thephoto-oxidized P680 retrieves the electron from a Mn4Ca cluster via a tyrosine, thelatter components are also called oxygen evolving center.
