Objective To measure the vertebral rotational centers in sagittal and transverse plane. These data may be quite valuable for the design of artificial disc. Methods Ten healthy volunteers of 40-60 years old were recruited under IRB approval and informed consent. Three-dimension lumbar spine models of L_2, L_3 and L_4 were reconstructed from MR scans. Spine motions were then reproduced using combined dual fluoroscopic imaging system (DFIS) and MR scan technique during flexion-extension and left-right twisting of the body. Based on the geometrical features of the vertebrae, ranges of motion (ROM) of 3 representative lo-cations were measured from anterior to posterior, the vertebral body center, the spinal cord canal center and the spinous process tip. Rotational centers of the vertebral segments were then located by calculating the point of zero ROM. Results Motion patterns: The ROMs of L_2 with respect to L_3 (L_(2,3)) and L_(3,4) increased pro-portionally from anterior to posterior locations. During flexion-extension motion, the vertebral body center moved within a range of 0.6 mm, while the spinous process tip moved within 7.5 mm in the sagittal plane. During left-right twisting, the vertebral body center moved within 1.0 mm, while the tip moved within 1.6 mm in the transverse plane. No statistical differences were found in the ROMs between L_(2,3) and L_(3,4). Rotational centers: the rotational centers of flexion-extension in sagittal plane for both L_(2,3) and L_(3,4) segments were located at posterior one-third of the vertebral body. The rotational centers of both L_(2,3) and L_(3,4) segments were located approximately 30 mm anterior to the front edge of the vertebral body. Conclusion The anterior portion of the vertebrae was found to have smaller ROM than the posterior portion. The vertebra rotates with the center of rotation located at approximately the posterior one-third of the vertebral body in sagittal plane. However, the vertebra rotates in transverse plane with respect to a point about 30 mm in front of the vertebra. The data indicated that the different portions of the vertebra have distinct motion characters during different motions.

Anterior cruciate ligament is the most important ligament to maintain the anterior and rotation stability of knee joint. Rupture of anterior cruciate ligament is one of the most common injuries of knee joint, and thus leads to knee instability and traumatic osteoarthritis. Anterior cruciate ligament reconstruction is usually performed to restore the anterior stability of knee joint, and is considered to reduce the secondary injury of medial meniscus, lateral meniscus and cartilage. Thus anterior cruciate ligament reconstruction can improve the function of knee joint. Traditional single bundle technique to reconstruct anterior cruciate ligament has been performed for many years. This technique can restore the anterior stability of knee joint and has excellent clini?cal results. Nearly 61%patients showed obvious radiographic osteoarthritis 20 years after anterior cruciate ligament reconstruction using bone-patella-bone graft. But, there is no agreement regarding to reduce the development of osteoarthritis after reconstruc?tion of anterior cruciate ligament. However, it has been reported that osteoarthritis would develop after reconstruction of anterior cruciate ligament in long term follow up study. Recently, with the further understanding of anatomy of biomechanics of anterior cru?ciate ligament, new techniques for anterior cruciate ligament reconstruction are developed, such as double bundle reconstruction, anatomic reconstruction and individual reconstruction. It remains controversial that whether these new technique can prevent the development of osteoarthritis after rupture of anterior cruciate ligament. Currently, no reconstruction technique for anterior cruci?ate ligament is perfect, and every technique has advantages and disadvantages. In terms of reducing the prevalence of osteoarthri?tis after reconstruction of anterior cruciate ligament, which technique is the best still remains unclear. New treatment and evalua?tion methods should be developed. In the future, not only the restoration of stability of knee joint should be considered, but also the articular cartilage contact kinematics including tibiofemoral joint and patellofemoral joint after anterior cruciate ligament recon?struction. Reduction of the development of osteoarthritis is an important topic after reconstruction of anterior cruciate ligament.

Objective To measure the range of motion (ROM) of the lumbar pedicle screw entrance point (LPSEP) in vivo during unrestricted motion under physiological weight bearing.Methods Eleven healthy volunteers aged 45-60 years underwent MRI scans in a supine position.Three-dimensional (3D) models of L2-5 were constructed.Next,each volunteer was asked to stand and was positioned in the following sequence:standing,45° flexion,maximal extension,maximal left-right twisting,while two orthogonal fluoroscopic images were taken simultaneously at each position.The MRI models were matched to the osseous outlines of the images from the two orthogonal views to determine the position of the vertebrae in 3D at each position.Coordinate systems were established to study the ROM of the LPSEP.Results The predominant translations were along anteroposterior and craniocaudal axis from supine to standing position (average,2.44mm and 2.35 mm).Rotation of the LPSEP occurred mainly around the mediolateral axis(average,3.91 °).During flexion-extension movements of the trunk,the predominant translation were along anteroposterior and craniocaudal axis and rotation were around mediolateral axis.During lateral bending and twisting,ROM of LPSEP did not rotate or translate in one dominant direction.Instead,the resulting motion represented a combination of rotation and translation in different directions.There was no significantly difference in translation and rotation between the three axis in L4,5segment (P＞0.05).Conclusion The kinematic behaviors of the LPSEP of the upper lumbar spine (L2,3 and L3,4) are similar which are different from that of the lower lumbar spine (L4,5).

The objective of this study is to fully investigate the therapeutic effect and mechanisms of action of Gegen Qinlian decoction (GD) on type 2 diabetes mellitus (type 2 DM). A rat model of type 2 DM was established with the combination of high-fat diet and multiple low doses of streptozotocin (STZ). Biochemical indicators related to glucose metabolism disorders, insulin resistance, oxidative stress were observed. The type 2 DM rats were administrated with GD for 80 days, the above-mentioned indexes were detected. The results indicated that the hepatic glycogen synthesis level was promoted, fasting blood glucose level and fasting blood insulin level were significantly reduced, insulin sensitivity index was significantly improved; the level of superoxide dismutase (SOD) was increased and the level of malondialdehyde (MDA) was reduced; pathologic morphology of pancreas and kidney was ameliorated in the GD group. It was indicated that the therapeutic mechanisms of action of GD on type 2 DM might be related to its effect of ameliorating glucose metabolism disorders, relieving insulin resistance, increasing the tissues' sensitivity to insulin, improving the antioxidative ability of living system, GD has therapeutic effect on type 2 DM and protective effects against damaged pancreatic function.
