BACKGROUND:In recent years, the spinal internal fixation technology has made rapid development based on biomechanics and material sciences.
OBJECTIVE: To review the biomechanical characteristics of the lumbosacral spine and the application of various internal fixation materials in the reconstruction of spinal stability after lumbosacral spinal tuberculosis.
METHODS:A computer-based search of Medline and Chinese Journal Ful-Text Database was performed for relevant articles using the keyword of “lumbosacral spinal tuberculosis, biomaterials materials, fixation” in English and Chinese, respectively.
RESULTS AND CONCLUSION: Rigid internal fixation is a conventional treatment for lumbosacral tuberculosis, which improves the spinal alignment and stability during the spinal reconstruction. Metalic materials such as stainless steel, titanium and titanium aloys have been widely used in rigid internal fixation, but metal sedimentation, non-transparency, stress shielding and osteoporosis after internal fixation impact the fusion effects and imaging observation. Absorbable materials as newly-developing materials have good biocompatibility and biodegradability in orthopedic internal fixation. To select the appropriate material for internal fixation, the biomechanical properties of internal fixation materials wil be investigated according to the degree of vertebral damage and lumbosacral stability.

The peptidyl-prolyl imide bond cis/trans isomerization of Xaa-Pro motif in the peptide and protein plays an important role to influence their conformation and function. Here, a series of model peptides including phosphorylated and its unphosphorylated counterparts were designed and synthesized. Preliminary 1H NMR experiments and molecular dynamics (MD) simulation were used to analyze the peptidyl-prolyl cis/trans imide bond isomerization. The data indicated that the side-chain O-phosphorylation of the Xaa residues preceding proline affected evidently the isomerization and thereby regulated the peptides conformations. The charges of the phosphate moiety as well as their steric effects might be the driving force for the conformational changes of these phosphopeptides.Moreover, the obtained most stable multiple configurations and their statistic cis/trans concentration distribution in MD simulation were basically consistent with the NMR experiments, which demonstrated that phosphorylation increased the cis conformation of the peptide and the maximum cis ratio is given while the phosphate group has no negative charge.

Objective To investigate the correlation between R219K (rs2230806 G/A) polymorphism in the ATP binding cassette transporter (ABC) A1 gene and ischemic stroke in a Chinese Han population. Methods A total of 360 patients with ischemic stroke and 358 healthy subjects were selected using a case-control study design. The patients with ischemic stroke were redivided into either a large artery atherosclerosis (LAA) group or a smal artery occlusion (SAO) group according to the TOAST criteria. Polymerase chain reaction-restriction fragment length polymorphism analysis and direct sequencing method were used to detect R219K (rs2230806 G/A) polymorphism in the ABCA1 gene. Results Using GG genotype as a reference, the AA genotype reduced the risk of ischemic stroke by 65% (odds ratio [OR] 0. 35, 95%confidence interval [CI] 0. 23 - 0. 55; P < 0. 001) and the onset risk of LAA by 77% (OR 0. 23, 95% CI 0. 13 - 0. 40; P < 0. 001), but it did not have significant correlation with SAO. The interaction of rs2230806 G/A polymorphisms with smoking, drinking, hypertension, and diabetes had no significant effect on the on-set risk of ischemic stroke (al P > 0. 05). AA genotype was enable to increase the high-density lipoprotein cholesterol levels of the patient group (OR 0. 35, 95% CI 0. 28 - 0. 42; P < 0. 001) and the control group (OR 0. 19, 95% CI 0. 14 - 0. 23; P < 0. 001) significantly, while it did not have significant correlation with the low-density lipoprotein cholesterol, total cholesterol, and triglyceride. Conclusions R219K (rs2230806 G/A) polymorphism in the ABCA1 gene may be associated with the reduced predisposition of ischemic stroke in a Chinese Han population, especialy LAA. The A alele may be a hereditary protective factor; its mechanism may be associated with the increase of high-density lipoprotein cholesterol levels.

Objective To investigate the correlation between methylenetetrahydrofolate reductase (MTHFR) gene 3 '-untranslated region rs4846049 G/T polymorphism and risk of ischemic stroke in a Chinese Han population. Methods A total of 396 patients with ischemic stroke and 378 healthy subjects (control group ) were selected using a case-control study design. Large artery atherosclerosis and small artery occlusion in the case group were 268 and 128 cases, respectively. Polymerase chain reaction-restriction fragment length polymorphism and the direct sequencing method were used to detect MTHFR gene rs4846049 G/T polymorphism. Results As compared to the GG genotype, the TT genotype significantly increased the risk of ischemic stroke (odds ratio [OR] 2. 87, 95% confidence interval [CI] 1. 43-5. 76;P=0. 003). Compared with G allele, T allele significantly increased the risk of the disease (OR 1. 62, 95% OR 1. 28-2. 06; P< 0. 001 ). Subgroup analyses showed that the rs4846049 G/T polymorphism could significantly increase the onset risks of LAA and SAO subtype stroke (all P<0.05). Conclusions MTHFR gene rs4846049 G/T polymorphism may be associated with the increased susceptibility to ischemic stroke in the Chinese Han population. The T allele may be a genetic risk factor for ischemic stroke in the Chinese Han population.
