A total of 45 patients with indication of vertebroplasty using unilateral approach were detected by CT scanning,2D and 3D reconstruction methods to measure the angle between vertebral pedicle and 1/3 of median horizontal plane,distance from skin needle entry point to spinous process at the horizontal plane as well as the declination angle between vertebral pedicle and sagittal plane.The three-dimensional anterior-posterior perspecitive images of vertebra were reduced to identify the entry point.The measurement results showed significant changes in introversion angle at T4-L5:T4-T8 was 23.75?-25.34?,T9-L1 was 25.74?-26.83?,and L2-L5 was 27.45?-41.57?;but minimal changes in declination angle at sagittal plane,from 19.17? to 25.24?;the open distance adjacent to the spinous process was increased from thoracic vertebra to lumbar vertebra:T4-T8 was 2.56?-2.87?,T9-L1 was 3.05?-3.61?,L2-L5 was 3.89?-8.23?.The best vertebral puncture point reduction was located at 9-11 points of the left,1-3 point of the right.Imaging-based measurements of introversion angle,declination angle,entry point and distance of spinous process at the horizontal plane are important data for percutaneous vertebroplasty.According to pedicle shape features at different stages,included angle,puncture point,path and depth,the vertebroplasty could be performed accurately and safely with reduced damage.Moreover,reliable data are provided for the design of a three-dimensional puncture-oriented device.

Objective To introduce the key issues of image registration in radiotherapy and study the performances of the three kinds of registry ways based on gray-scale registration, included mean-square measure, normalized correlation measure and mutual information measure. Methods After analysis of elements of the matching algorithm, the different registration algorithm performance are evaluated by the use of a comprehensive registration error based on C ++ to be realized, which can compare with the evaluation results of traditional target registration error. Results All three kinds of measure can both match accurately in plesiotype model images, which registration accuracy and speed in the standard of mutual information measure is more stable, integrated registration error is only half of the other two measures. Conclusion The comprehensive evaluation result by using registration error is more objective, the mutual information measure is better registration measure in radiotherapy.

Objective To observe the changes of body fat content, bone mineral content and lean body weight before and after antiobesity acupuncture. Method Thirty seven cases of simple obese women were acupunctured by syndrome differentiation. Indicators related to obesity, body fat content, bone mineral content and lean body mass were measured and statistically analyzed before and after treatment. Results Acupuncture significantly improved objective indicators of obesity (BMI, waist, hip and arm circumference), reduced body fat content (whole body, upper limbs, torso), lowered lean body mass (body, upper and lower limbs), and had no effect on bone mineral content. Conclusion Acupuncture weight loss has no side effects of reducing bone mineral density, especially fits for patients with abdominal obesity (lipid-decrease and no lean-reduction on torso).

Contradictive issues in terms of implementing "sero-sorting" are also discussed in this article to provide some information for further conducting MSM related interventions in China.

Objective To observe the effects of soybean isoflavone in attenuating trans fatty acids-induced athero-sclerosis in rats .Methods The rats were randomly divided into normal diet group、trans fatty acids group、soybean isoflavone group and trans fatty acids +soybean isoflavone group .Research kit was used to test the amounts of TG , HDL,LDL and IL-6,TNF-αin rats'blood.Bovine aortic endothelial cells were cultured and divided into control group,trans fatty acids group and trans fatty acids group +soybean isoflavone group .Western blot was performed to test the NF-κB phosphorylation ,as well as to determine ICAM-1 and VCAM-1 protein contents in bovine aortic endo-thelial cells.Results Compared with normal diet group ,the amounts of TG,LDL,IL-6,TNF-αincreased evidently (P<0.05), whereas the amounts of HDL decreased evidently (P<0.05) in the rats'blood of trans fatty acids group . After the soybean isoflavone intervened ,the amounts of TG,LDL,IL-6,TNF-αall decreased (P<0.01), meanwhile the amounts of HDL increased significantly (P<0.01).Soybean isoflavone inhibited NF-κB phosphorylation induced by trans fatty acids ( P<0.01) .The high expression of ICAM-1 and VCAM-1 induced by trans fatty acids was de-creased by soybean isoflavone when comparing with those in the control group ( P<0.01 ) .Conclusions Soybean isoflavone has a role in attenuating trans fatty acids trans fatty acids-induced atherosclerosis in rats .

Dental impressions are widely used in the field of oral restoration. The materials are used for making impression in oral cavity. In order to measure the thickness of impression for reference in clinic, the real impressions are taken as the object for studying. Through optical method, charge-coupled device (CCD) is used for collecting the grey image of cutting section of the impressions which are located in the same plane with steel dividing ruler. According to convert relationship between dividing ruler and pixels collecting grey image, the thickness of impression specimens can be obtained. The results show that the optical method used for measuring thickness is feasible to the task and the precision can reach micro dimension. The experiment method and technique can also be provided for measuring thickness of similar tissue engineering materials.
