The results are as follows:(1) With the imposing of orthopedic force of simulating maxillary protraction on maxilla, in the sagittal direction, the maxillary complex of the SD Rats in experimental group grows more quickly than that in two control groups, and the extent of the maxillary complex increases more evidently. The maxillary complex displays anti-clockwise forward and upward rotation.(2) With the imposing of orthopedic force on maxilla, upper incisors exhibit labial-inclined, labioclination of lower incisors changes insignificantly, and the shape and the dimension of skull are not affected significantly.(3) The expression of TGF-3 , in frontomaxillary sutures and palatomaxillary sutures shows different intensity in different extent of time. But The expression of TGF-{3, in experimental group is more intensive than that in two control groups, and that in operated control group and natural growth group has no significant difference.

There was a good correlation between Ptw,AVCtw,MVOtw,PTV,PUV,UntwR and age.2.Assessment of left ventricular twisting and untwisting of DCM patients19 DCM patients(range 18-80 yr,mean age 50.52±17.52 yr,2 females) and 21 age- and sex-matched normal controls(range18-80 yr,mean age 49.05±16.94 yr,5 females) were enrolled into this study.Then DCM patients were divided into two groups:E/A＜2 group and E/A＞2 group.The routine echo showed the left ventricle dilated and EF decreased.The results show that LV rotation degree, rotation velocity at baseline and apex were irregular changeable with the cardiac cycle;the rotation direction was clockwise at the base and counterclockwise at the apex,and are combined to yield a systolic counterclockwise twisting as seen from the apex,but the rotation at the basal and apex were the same direction in some patients.
