BACKGROUND: The biomechanics of cervical spine is complicated. It is an important way to select the appropriate biomechanical model and research method so as to explore the diagnosis and evaluation mechanism of cervical spine injury and prognosis judgement.OBJECTIVE: To discuss the alternation of cervical biomechanics after the degeneration of cervical disc and the influence of degeneration on cervical stability.METHODS: (1) A three-dimensional finite element model of cervical spine was established from the CT scan images of cervical spine of a healthy male volunteer, Solid-Works2015, HyperMesh and ANSYS11.0. We created a cervical three-dimensional finite element model. To simulate the degenerative disc by modified the mechanical characters and height of the disc model, we observed the biomechanics of the impact on the cervical spine (the range and the stress on intervertabral disc).RESULTS AND CONCLUSION: (1) The entire model with a total of 97705 nodes and 372896 elements. Ligament and joint capsule were also constructed. Face to face contact element was used in the facet joint, with complete structure and high accuracy of measurement of spatial structure. (2) The range of motion of cervical spine increased during degeneration compared with normal cervical segments (P < 0.05). (3) Intervertebral disc degeneration caused angle increase at disc and motion segment. Osteophyte formed on vertebral edge. Intervertebral disc degeneration caused cervical instability. Simultaneously, instability increased the disc degeneration.

Objective To observe the results of preventing knee postoperative adhesions after synovectomy by chitosan membrane. Methods Thirty-two New Zealand white rabbits were randomly divided into two groups, the chitosan membrane experimental group and the control group. All animals underwent synovectomy of the right knee joint. Chitosan membrane was inserted in the suprapatellar pouch areas in the experimental group, whereas no film was inserted in the control group. After operation, the knee joints were immobilized with a plaster cast for 4 weeks. Rabbits in each group were assessed macroscopically, semiquantitatively, biomechanically and biochemically. All quantitative data were analysed by t test. Results Macroscopical finding: dense fibrous adhesion was observed in the control group, whereas little adhesion was found in experimental group. The former groups scores was higher than the later groups(P

Objective:To explore the correlation among ECG indexes,myocardial enzyme peak and short term cardi-ac function in patients with acute anterior ST elevation myocardial infarction (STEMI).Methods:A total of 150 pa-tients with acute anterior STEMI were selected from our hospital.According to left ventricular ejection fraction af-ter three months (3m LVEF),they were divided into cardiac dysfunction group (n=78,LVEF<50%)and normal cardiac function group (n= 72,LVEF≥ 50%).Following indexes were compared between two groups,including sum of ST elevation extent (ΣST),R wave (ΣR),Q wave (ΣQ),maximum value of ST elevation (STm)and Q wave (Qm)etc.on infarct related leads,and peak value of creatine kinase (CKm),CK isoenzyme (CK-MBm)and cardiac troponin T (cTnTm)etc.Results:Compared with normal cardiac function group,there were significant rise in ΣST,ΣQ,STm,Qm,CKm,CK-MBm,cTnTm,left ventricular end-diastolic diameter (LVEDd),3mLVEDd and significant reduction in ΣR and LVEF,3mLVEF in cardiac dysfunction group,P <0.05 or <0.01;Spearman correlation analysis indicated that ΣST,ΣQ,STm,Qm,CKm,CK-MBm and cTnTm were positively correlated with 3m LVEDd (r =0.18~0.63,P <0.05 or <0.01),and inversely correlated with 3m LVEF (r =-0.88~-0.42, P <0.01 all).ΣR was inversely correlated with LVEDd and 3m LVEDd (r =-0.46、-0.51,P <0.01 both),and positively correlated with LVEF and 3m LVEF (r =0.81,0.71,P <0.01 both).Conclusion:In patients with ante-rior STEMI,the higher ST elevation,the higher Q wave,the lower R wave,the higher myocardial enzyme peak is, the poorer short term cardiac function is.

BACKGROUND:In the development of nervous system, the main effect of sonic hedgehog signaling pathway is to induce the partition of dorsal and ventral sides in the central nervous system. When above signaling pathway is destroyed, ventral neurons in the central nervous system wil completely lose. OBJECTIVE: To establish adult rat models of acute compressive spinal cord injury, to detect the expression of development-related sonic hedgehog after acute compressive spinal cord injury, and to explore its effects on neural regeneration. METHODS:A total of 30 Sprague-Dawley rats at the same age were placed in a posterior compression device to establish models of acute compressive spinal cord injury. They were then randomly divided into lamina driling group (n=5) and acute spinal cord injury group (n=25). Sonic hedgehog mRNA was detected by in situ hybridization method at the injury site at 1, 3, 5, 7, and 14 days after spinal cord. RESULTS AND CONCLUSION:The expression levels of sonic hedgehog increased to the maximal expression levels in grey and white matters 10 mm distal to the lesion site at 7 days after injury. Sonic hedgehog expression was apparently less in ependymal cels than in grey and white matters and was restricted to 5 mm distal to the lesion site, being narrower in its distribution than its occurrence in grey and white matters. These data indicated that acute compressive spinal cord injury can induce the expression of sonic hedgehog. This expression maybe relates to adult neural cel regeneration.
