心脏瓣膜的

The valve replacement with partly or whole mitral valve structure can improve the ventricular internal diameter, ejection fraction, cardiac index and stroke volume, thus improving cardiac function. However, bicuspid valve restenosis should be avoided through active observation.

保留部分或全部二尖瓣结构的瓣膜置换能更好地改善左心室内径大小、射血分数、心指数、每搏输出量，从而改善心脏功能，但要积极观察以避免出现二尖瓣再狭窄。

Methods morphology ,opening,closing and hemodynamicon short axes section of large arteries and on long axessection of aorta were observed.results thickening,calcification ,hemodynamic,morphologic changes of the aortic wall were exacerated with increased age of patients.conclusion cdfi is of great valve in diagnosing bicuspid aortic valve.

重点通过大动脉短轴及主动脉长轴等切面观察二叶式主动脉瓣的形态、回声、启闭及血流动力学情况。结果：随着年龄的增长，瓣膜增厚、钙化、血液动力学、心脏形态学改变逐渐加重。结论：彩超对先天性二叶式主动脉瓣畸形及病变的诊断具有重要意义。

The results of ultrosonic cardial gram and the changes of cardiac function before and after operation were compared.

方法回顾性分析92例巨大左心室患者行心瓣膜置换术的临床资料，对比分析术前、术后不同时间心脏超声心动图检查结果和心功能变化。

There were no nick infection, chorioamnionitis and other complications. Eight/sixteen fetal lambs were undergone intro-utero cardiac intervention. The values of body weight and Hct of lambs which were executed. pre-term and full-term delived were (1.77±0.14) kg vs.(2.15±0.23) kg vs.(2.41±0.19) kg and 29%-33% vs. 27%-35% vs. 37%-41%. In autopsy, hydropericardium was found in 4/8 with 1-2.5 mL and 1/8 with 5 mL. Besides 1/8 with interventricular septum centesis injury, there was no centesis damage to endocardium, valve, chordae tendineae, papillary muscles and aortic tunica intima.

病理解剖发现施行手术的8例胎羊/新生羊胸壁穿刺点均位于左侧心前区，心脏进针部位在左室心前区近心尖部位6例，近流出道1例，近室间隔1例；4只少量心包积液(1~2.5 mL)，1只心包积液5 mL，3只未发现心包积液；除1只胎羊有室间隔穿刺伤外，其余胎羊心内膜、瓣膜、腱索、乳头肌及主动内膜均未发现损伤；未发现肺、肝等胸腹腔脏器穿刺损伤；均未发现心包、胸腔感染迹象。

To investigate the use of warfarin sodium after mechanical heart valve replacement.

目的 研究心脏机械瓣膜置换术后华法林钠的应用。

Introduction: Aortic stenosis is the most common valvular heart disease in westernised societies.

背景：动脉瓣狭窄是西欧国家常见的瓣膜性心脏疾病。

In aortic stenosis, calcium deposits narrow the aortic valve and impair the heart's ability to pump blood.

在主动脉狭窄病例中，钙质沉淀使得主动脉瓣膜狭窄，损害了心脏的供血能力。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
