The results show that both of relative rate and synonymous and non-synonymous coden substitution in eudicot clade are significantly higher than those in monocot clade, and the value of dN/ds uncovered possible positive selective pressure in eudicot clade.

结果表明：真双子叶植物分支中SQUA类基因的相对速率和同义与非同义置换位点均显著高于单子叶植物分支；同时，dN／dS值表明真双子叶植物分支中可能存在正选择压力。

MUF could improve pulmonary function after cardiac valve replacement.

改良超滤技术能够改善心脏瓣膜置换术后患者的呼吸动力学。

objective to evaluate the effect of modified ultrafiltration on pulmonary function after cardiac valve replacement.methods 46 patients who underwent mitral valves replacement were randomly divided into muf group(n=24) and control group(n=22) without muf.

目的 观察改良超滤对心脏瓣膜置换术患者肺功能的影响。

Methods Sixty-seven cases of adult patients undergoing valves replacement were randomized into modified ultrafiltration group (n=33) and control group (n=34). Blood gas parameter such as PO2, PCO2 were measured at pre-cardiopulmonary bypass, end CPB, and post MUF (or 20 min post CPB in control group). Ventilatory support time, usage time and amount of vasoactive drug and ejection fraction of left ventricular were also measured in the early period of operation.
