拜读《中华老年医学杂志》2013年第10期刊登的《甲基强的松龙联合布地奈德雾化预防气管插管拔管后咽喉部不适的临床观察》一文,得益匪浅.但亦觉得文中将布地奈德雾化吸入用来预防气管插管拔管后咽喉部不适的方法值得提出商榷.该文将气管插管患者分为A组（拔管前静脉使用甲基强的松龙40 mg组）和B组（拔管前静脉使用甲基强的松龙40 mg联合拔管后即刻予以布地奈德1 mg雾化组）,结果显示,A组咽痛发生率为50.0％、声嘶为55.6％;B组咽痛发生率为30.8％、声嘶为35.7％;喉头水肿发生率A组为5.6％,B组为2.6％,两组虽差异均无统计学意义,但B组发生率较A组呈下降趋势,认为气管插管拔管前使用甲基强的松龙且拔管后即刻予以布地奈德雾化吸入可减少拔管后患者咽痛、声嘶和喉头水肿的发生率.对此,谈谈我们的看法.

The recent stochastic signal observed jointly by NANOGrav,parkes pulsar timing array,European pulsar timing array,and Chinese pulsar timing array can be accounted for by scalarinduced gravitational waves(SIGWs).The source of the SIGWs is from the primordial curvature perturbations,and the main contribution to the SIGWs is from the peak of the primordial curvature power *** effectively model this peak,we apply the Taylor expansion to parameterize *** the Taylor expansion parameterization,we apply Bayesian methods to constrain the primordial curvature power spectrum based on the NANOGrav 15 year data *** constraint on the primordial curvature power spectrum possesses a degree of generality,as the Taylor expansion can effectively approximate a wide range of function profiles.
