目的:比较不同跨肺压(PtP)指导下机械通气治疗急性呼吸窘迫综合征(ARDS)患者的疗效。方法:选择2016年10月-2019年2月本院收治的81例ARDS患者为研究对象,根据指导方式及不同PtP水平分为A组(PtP=10 cm H2O)、B组(PtP=20 cm H2O)和对照组(...目的:比较不同跨肺压(PtP)指导下机械通气治疗急性呼吸窘迫综合征(ARDS)患者的疗效。方法:选择2016年10月-2019年2月本院收治的81例ARDS患者为研究对象,根据指导方式及不同PtP水平分为A组(PtP=10 cm H2O)、B组(PtP=20 cm H2O)和对照组(最佳氧合法),每组27例。比较各组机械通气治疗后不同时间点呼吸动力学指标(肺容积、Cst、PIP、Pplat、PEEP)和血流动力学指标(HR、MAP、CVP、CI),同时详细记录各组临床指标。结果:治疗后24、48 h,三组呼吸动力学指标比较,差异均有统计学意义(P<0.05),其中A、B组肺容积、Cst、PIP、Pplat、PEEP均高于对照组(P<0.05)。治疗后24、48 h,三组MAP、CVP、CI比较,差异均有统计学意义(P<0.05),其中B组MAP、CVP、CI均低于对照组(P<0.05);三组治疗前后HR比较,差异均无统计学意义(P>0.05)。B组机械通气治疗时间、住院治疗时间均短于对照组和A组,差异均有统计学意义(P<0.05);A组机械通气治疗时间、住院治疗时间与对照组比较,差异均无统计学意义(P>0.05);三组28 d病死率比较,差异均无统计学意义(P>0.05)。结论:不同PtP指导下机械通气均可改善ARDS患者呼吸功能,但PtP为10 cm H2O指导下机械通气对血流动力学影响较小,建议临床应用中优先使用。展开更多

With its complete genome sequence available, it is possible to analyze protein-protein interactions from a whole- genome standpoint. Here we combine four recently developed computational approaches (gene fusion method, gene neighbor method, phylogenetic profiles method, and operon method) to predict protein-pro- tein interaction networks of Leptospira interrogans strain Lai. Through comprehensive analysis on in- teractions among proteins of motility and chemotaxis system, signal transduction, lipopolysaccaride bio- synthesis and a series of proteins related to adhesion and invasion, we provided information for further studying on its pathogenic mechanism. In addition, we also assigned 203 previously uncharacterized proteins with possible functions based on the known functions of its interacting partners.
