一见室速就紧张?缓急有别处理攻略

室性心动过速(室速)是风险较高的心律失常,可与室颤及猝死相关.然而,并不是所有的室速均需高度紧张,立即处理.例如,多形性室速风险极高,需要立即电复律;相反,单形的非持续性室速甚至可见于正常人.本文拟结合今年8月发布的《室性心律失常中国专家共识》以及2014年欧洲EHRA/HRS/APHRS《室性心律失常专家共识》,谈谈遇到室速,如何做到「缓急有别,妥善处理」.

输液配制中微粒产生原因与后果

<正> 随着大输液治疗用量的扩大和临床的广泛应用,质量要求愈加严格,其中重要指标之一是不溶性微粒的限量必须符合规定。大输液微粒系指来自生产使用过程中由多种途径污染的肉眼难以发现的微小颗粒杂质(肉眼可以见到50μm 以上者通常称为异物)。它不溶于水,在人体内亦不被代谢。按生产要求,澄明度检查不可能发现,这种微小颗

不同门奇断流术式对门静脉高压症犬食管下段血管再生的影响

Objective To explore the effect on blood vessel regeneration of distal esophagus in ca-nines of portal hypertension with liver cirrhosis after different procedures with paraesophagastrie devascular-ization. Methods Portal hypertension models were produced in canines by subcutaneous injection of 60% CC14 combined with food restriction. Forty eight model canines were randomly divided into 4 groups: group A, traditional paraesophagastrie devascularization;group B, selective paraesophagastric devascularization;group C, paraesophagastric devascularization plus distal esophageal transaction and reanastomosis with sta-pler;group D,control group. Every group had 12 canines which were randomly divided into A1 ,B1 ,C1 ,D1, A2,B2,C2 and D2 groups after the operation. Canines in groups A1 ,B1 ,C1 and D1 were executed at first month after the operation,and those in groups A2, B2, C2 and D2 were executed at the 6th month after the operation. The distal esophagus was segmented when the canines were executed. The upside and downside of the stoma in group C were distinguished and signed as Ca and Cb. Immunohistochemieal methods were used to detect VEGF,CD34 and FVⅧ-Rag,blood vessel-related factors,in lower esophagus. Results The expres-sion levels of VEGF and CD34 MVD,FⅧ-Rag MVD in groups A1 ,B1 and C1 were lower than those in group D1 one month after the operation (P <0.05). All the indices in group B1 were lower than those in groups A1 and Clb,but higher than those in group Cla (P <0.05). The indices in group Cla were lower than those in group C1b (P < 0.05 ). The indices in groups A2 and B2 were higher than those in groups A1 and B1, re-spectively at the 6th month after the operation (P <0.05). They were higer in outer membrane in group C1a than in group C2a (P <0.05). The indices in group C2b were higher than those in group Clb (P<0.05). Conclusion At the first month after operation, the expression of blood vessel-related factors was declined in three different procedures of paraesophagastric devascularization,which indicated that all three different pro-cedures could diminish the vessels in distal esophagus. The effect in group C was most obvious among all groups. At the 6th month after traditional paraesophagastrie devascularization and selective paraesophagastrie devascularization, the expression of blood vessel-related factors in distal esophagus was declined. But there were no significant changes in the expression of blood vessel-related factors in distal esophagus after parae-sophagastric devascularization plus distal esophageal transaction and reanastomosis with stapler. It indicated that the blood vessel regeneration in paraesophagastric devascularization pins distal esophageal transaction and reanastomosis with stapler was inferior to that in other procedures.

新意马铃薯

不知何时“土豆”这个词变成了形容一个人落伍的代名词，其实土豆很冤枉，不仅仅因为它几乎一年四季赶得上餐桌菜肴的大队，更因为它其实可以被烹饪得很“洋”，马铃薯在西餐餐桌上有着举足轻重的地位，对于我们来说，最可贵的是马铃薯所含的维生素C在任何形式的烹调中都是最稳定不易流失的。[编者按]
