and Results— In 104 patients with idiopathic dilated cardiomyopathy who underwent annuloplasty for functional MR, basal mitral anterior leaflet angle, distal mitral anterior leaflet angle, posterior leaflet angle, coaptation depth, tenting area, mitral annular dimensions, left ventricular volumes, and MR severity were quantified by echocardiography before surgery and at 6-month intervals after it.

方法和结果：104名存在功能性MR的原发性扩张性心肌病患者接受了成形术。术前采用超声心动图检查获取基线二尖瓣前叶夹角、二尖瓣前叶远端夹角、二尖瓣后叶夹角、接合深度、幕状区面积、二尖瓣瓣环大小、左室流量以及MR程度，术后6个月复查。

The nitrate non-utilizing mutantas an another added genetic marker was used to select the out-crossed perithecium from self-crossed perithecia. Seven crosses were tested in all, including cross between S×S, MR ×S, MR×MR,HR ×S, as well as HR ×MR. The results showed that no recombinant phenotype was found among all progeny of seven crosses. Progeny segregation of crosses between the parents with different sensitive levels (i.e. MR×S, HR×S,HR×MR) clearly fit a 1:1 ratio of two parental phenotypes, and no segregation was found in the crosses of S×S and MR × MR.

从25个敏感菌株和31个抗性菌株中随机挑选了2个S、3个MR和1个HR，并以硝酸盐营养缺陷型突变体作为另一个遗传标记，按照S×S、MR×MR、MR×S、HR×S、HR×MR等共设计了7个杂交组合，对各杂交后代对多菌灵的敏感性测试发现，在所有杂交后代中均未出现除双亲表现型以外的重组型个体，MR×S、HR×S及HR×MR的杂交后代出现了1∶1的分离比例。

Results: The atherosclerotic model was successfully established in rabbits. T1 WI, T2 WI and PDWI sequences scanning showed thickening of aortal wall and the plaque showed equal, high or low signal intensities, which was in good accordance with the pathological examination results. The atherosclerotic plaques were successfully detected and analyzed by MR and MR had higher accuracy than ultrasound examination.
