心脏瓣膜的

Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.

结果 60例瓣膜手术患者术前cTnT均在正常值范围内，主动脉开放后2 h时，阻断时间和cTnT的相关系数为r=0.875(P＜0.01)，回归方程为Y=0.019X-0.026；其中20例瓣膜手术患者心脏经过阻断后，心电图有缺血性改变，周围血液中的CK、CK-MB和cTnT均有明显升高，分别在关胸后2 h达到高峰，数值分别为术前的12.6、9.2和257倍；18例行动脉导管结扎和心包剥脱术的患者术前和关胸后的心电图和血液中的cTnT均正常，CK和CK-MB除2例心包炎患者关胸后出现明显变化外，余均未见改变。

Anyone can develop endocarditis, but you are most at risk if you have underlying heart valve disease or have certain congenital heart diseases.

任何人都可以发展性心内膜炎，但你是最危险的如果你有潜在的心脏瓣膜病或有一定的先天性心脏病。

Rheumatic fever, once the most common cause of joint problems in children, and the commonest cause of heart-valve disorders, is now fortunately rare in the developed world.

风湿热，一旦最常见的原因联合的问题，在儿童，最常见的原因，心脏瓣膜疾病，所幸的是现在难得在发达世界。

Cardiac hypertrophy is one of adaptive responses of the heart to a variety of pathological stimuli, including hypertension, myocardial infarction, congenital heart disease, heart valvula disease, and perturbations in sarcomeric function due to altered expression or mutations of contractile proteins. Increase in wall tension and hormonal stimuli are thought to directly activate various membrane-bound receptors and signal transduction cascade within cardiomyocytes resulting in the activation of immediate early genes and responsive genes such as c-jun, c-fos, c-myc, egr-1, ANF, BNP. Then the expression of construction proteins such as MLC-1, skeletal α-actin was unregulated.

As comedian and actor Robin Williams , 57, and 83-year-old former first lady Barbara Bush found out recently, in many cases, the valves don't last a lifetime; some become leaky. Called a regurgitating valve , this allows pumped blood to wash back into the heart.

根据57岁的喜剧演员RW和前83岁的前第一夫人BB的情况最近人们发现，在一些情况下，瓣膜并不能终生正常工作，一些开始泄漏，这被称为瓣膜回流，这种情况下被泵出的血液回流到心脏。

The production of iable biological heart ales is of central interest in tissue engineering.

中文摘要：生产有活力的生物心脏瓣膜是组织工程领域中重要的方向。

A motion tracking model based on the Mumford-Shah segmentation model and a parameter estimation method based on the level set value is proposed to track the motion of the heart mitral valve and estimate its motion parameter.

5提出了基于M-S模型的运动目标检测方法和一种基于水平集函数值的参数估计方法，并应用于心脏超声图像二尖瓣膜的运动检测。

Each year the lives of millions patients are saved with artificial heart valves and liver as well as artificial kidney and left heart assistant device. And innumerable artificial organs are used to rehabilitate people's organ defect.

从人工心脏瓣膜到人工肝肾和左心辅助装置等，每年可挽救数百万危重患者的生命；而每年用于修复人体缺陷的人工器官更是不可胜数。

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。
