The CAPN10 gene, which encodes calpain-10 ( CAPN10 ), a nonlysosomal cysteine protease expressed in many tissues, including skeletal muscle, liver, and pancreas, was positionally cloned within the NIDDM1 region. This putative diabetes susceptibility gene encodes a 672 amino-acid protein. Horikawa et al, determined that the CAPN10 gene consists of 15 exons and spans 31 kb. Recently, researchers in many countries have examined the impact of CAPN-10 gene on T2DM. The three SNPs existence simultaneously can increase threefold risk of T2DM. The correlation between them with racial diversity is also reviewed.

BACKGROUND:Typical anterior cervical decompression and fusion method has many disadvantages.Cervical fusion cage has obtained satisfactory outcomes,but many problems should be solved.OBJECTIVE:To design a type of PDLLA Cage and to investigate the immediate stability of different fusion methods in a goat cervical spine model following C_(3-4) fusion.DESIGN,TIME AND SETTING:Randomized controlled study was performed at the Laboratory of Biomechanics,Sichuan University from June 2005 to January 2006.MATERIALS:C_(3-4) segment was obtained from a total of 15 adult female 2-year goat corpses.Additional C_(3-4) from 27 adult female 2-year goats was used in biomechanics test.Samples were supplied by the Animal Experimental Center,West China Clinical Medical College,Sichuan University to use in measurement of anatomy parameter and biomechanica test.METHODS:C_(3-4) segment obtained from goat corpse was subjected to X-ray test in an anterior lateral position.In accordance with C_(3-4) mean vertebral height,the angle of C_3 vertebral inferior border and anterior border,the anterior and posterior distance of C_3 vertebral inferior border,as well as the distance of anterior and posterior borders of the middle vertebral body,a type of PDLLA Cage was designed and made,and the biomechanical behavior analysis about the materials was performed.The 27 goat samples were not destroyed following biomechanics test (normal control group),and were assigned to 3 groups,PDLLA Cage group (n=9),titanium alloy Cage group (n=9) and autologous iliac bone group (n=9).Anterior longitudinal ligament was incised at FSU intervertebral space.Following excising the nucleus pulposus,adherent muscle was removed and the whole ligament was remained,as well as the bony terminal plate and cartilage subchondral bone were reserved.PDLLA Cage and titanium alloy Cage were respectively implanted in the cavity of the Cage main body in the PDLLA Cage group and titanium alloy Cage group.The Cage was fixed in the vertebral body using two fixing plates of anterior alar plate with 3.5-mm screw.Autologous cortical iliac bone from three surfaces was implanted in the autologous iliac bone group.MAIN OUTCOME MEASURES:Biomechanics was tested in flexion,extension,axial rotation,and lateral bending using 1,2,3,4 N·m moment of force method.The mean stiffness values and the range of motion were calculated in each group. RESULTS:In every loading mode,the displacement values were statistically significant difference between cage groups (PDLLA Cage group and titanium Cage group) compared with the normal control group (P<0.05);and the displacement of cage groups were lower than that of the autologous tricortical iliac crest bone graft group except for 4 N·m bending loading mode (P<0.05).Posterior extension was significant better in the PDLLA Cage group and titanium alloy Cage group compared with the autologous iliac bone group.Compared with the normal control group,the displacement of posterior extension and lateral bending was lower in the autologous iliac bone group (P<0.05).The stiffness of PDLLA Cage and the titanium Cage group in the flexion loading had no significant difference (P>0.05).In the others loading condition,the titanium Cage group was statistically greatest in all directions (P<0.05).The stiffness of PDLLA Cage was comparable with that of the titanium Cage and was statistically higher than that of the autologous tricortical iliac crest bone graft and intact (P<0.05).CONCLUSION:This type of PDLLA Cage can provide enough primary stability for cervical intervertebral fusion.

Objective To design a type of poly (D, L) Lactide (PDLLA) cage, compare the characteristics of inter body fusion using PDLLA cage with those of titanium cage and autologous tricortical iliac crest graft in a goat cervical spine model in vi?vo. Methods Twenty?four goats underwent C3-4 discectomy and fusion were assigned to 3 groups, PDLLA cage group (n=8), titani?um alloy cage group (n=8) and autologous iliac bone group (n=8). Radiography was performed pre?and post?operatively and 1, 2, 4, 8, and 12 weeks after operation. At the same time points, disc space height (DSH), intervertebral angle (IVA), and lordosis angle (LA) were measured. After 12 weeks, the goats were killed and fusion sites were harvested. Biomechanical testing was performed in flexion, extension, axial rotation, and lateral bending to determine the stiffness and range of motion. All cervical fusion speci?mens underwent histomorphological observation. Results The IVA of PDLLA cage 4 weeks after operation and DSH 8 and 12 weeks after operation was statistically greater than that of autologous iliac bone graft (P<0.05). The LA values were shown no signif?icant difference among PDLLA cage, Titanium cage and autologous iliac bone graft groups. The stiffness of two types of cages in ax?ial rotation and lateral bending, the ROM in every movement was statistically greater than that of autologous iliac bone graft group (P<0.05). PDLLA cage and Titanium cage had no significant difference (P>0.05). Radiographic and histomorphological observa?tion showed better fusion results in cage groups than in autologous bone group. Conclusion This type of PDLLA cage has excel?lent biocompatibility and can provide an appropriate biological environment for bone ingrowth and osteogenesis at bone?implant in?terface. Furthermore, PDLLA cage can maintain DSH and increase the stability of fusion segments to create a good biomechanical environment for the last bone fusion.
