BACKGROUND:Cervical decompression and fusion internal fixation wil accelerate adjacent segment disc degeneration, and it is not clear whether single segment instaibility can increase the adjacent segment disc degeneration. OBJECTIVE:To study the changes of morphology, proteoglycan and col agen type Ⅱ in the adjacent intervertebral disc of the cervical instability models. METHODS:Sixteen New Zealand white rabbits were divided into two groups randomly, with eight rabbits in the control group and eight rabbits in the model group. The animal cervical instability models were made by destroyed partly annulus fibrosus and absorbed C 5/6 nucleus pulposus through anterior cervical puncture. After 12 weeks, the animal models were tested by X-ray film. Al rabbits were sacrificed and 10 mg nucleus pulposus of the intervertebral discs of C 4/5 cut from sagittal plane were harvested and stored under 0 ℃. The content of proteoglycan in nucleus pulposus was tested with phloroglucinol method. Then, the paraffin sections of intervertebral disc tissues were taken for hematoxylin-eosin staining and SABC immunohistochemical staining. RESULTS AND CONCLUSION:The notochord cells of C4/5 intervertebral discs in the experimental group was decreased, and being replaced by fibroblast-like cells. Round chondrocytes could be seen occasional y and intervertebral discs annulus fibrosus became rough and arranged disorderly, the hyaline degeneration and pigmentation were observed as wel as the fibrochondrocytes, and there was a gap between inner and outer annulus fibrosus. The content of proteoglycan was decreased in the nucleus pulposus, and there was significant difference between two groups. The col agen type Ⅱ in the degenerative disc nucleus pulposus and annulus fibrosus of the experimental group was lower than that of the control group. Cervical instability can lead to adjacent intervertebral disc degeneration with the morphological changes and decreased content of proteoglycan and col agen type Ⅱ.

BACKGROUND:Destroying posterior stable structure of cervical vertebra may facilitate the ligamentum flavum regeneration. Whether anterior cervical instability can induce the regeneration in posterior and adjacent ligamentum flavum remains unclear.
OBJECTIVE:To observe the changes of transforming growth factor-β1 expression and histopathology in the ligamentum flavum of cervical instability animal models.
METHODS:Thirty-six New Zealand white rabbits were randomly divided into control group and experimental group, with 18 rabbits in each group. In the experimental group, cervical instability animal models were established made through destroying annulus fibrosus by anterior puncture and absorbing nucleus pulposus in C4/5 . And no intervention was given to the control group.
RESULTS AND CONCLUSION:Compared with the control group, fibers in the C 3/4, 4/5, 5/6 ligamentum flavum arranged disorderly and the glass like degeneration was found in the experimental group. The expression of transforming growth factor-β1 in ligamentum flavum was increased, especial y in C 4/5 , in the experimental group. At 4, 8, 12 weeks, transforming growth factor-β1 expression in the C 3/4, 4/5, 5/6 ligamentum flavum segments was similar between the two groups. Experimental findings indicate that, anterior cervical instability can induce the regeneration in posterior ligamentum flavum, especial y in the injured segment.

Objective To investigate the preliminary clinical result of thoracolumbar fracture combined with posterior ligamentous complex injuries repaired by posterior transpedicular screw fixation.Methods A retrospective review was performed on 22 patients with thoracolumbar flexion-distraction fracture combined with posterior ligamentous complex injuries treated with transpedicular screw fixation from July 2008 to March 2013.There were 16 males and 6 females with mean age of 39 years (range,23-62 years).After medically stable,posterior pedicle screw fixation was performed under intravenousinhalational anesthesia.According to the degree of fracture displacement and types of ligament injury,posterolateral bone grafting or intervertebral fusion at the level of injury was conducted.Vertebral height restoration,Cobb' s angle and American Spinal Injury Association (ASIA) score were reviewed preoperatively,at postoperative 3 days and at the last follow-up.Results All the patients were operated on smoothly.There were no complications during operation.All the patients were followed up for 5-51 months (mean,26.5 months).Fracture reductions were satisfied with the closure of vertebral posterior element.Mean anterior vertebral height and Cobb' s angle improved by 20.6％ and 10.60°respectively after operation (P ＜0.01).Eight patients with neurological dysfunction showed some recovery after operation with the mean sensory score improved by 20.7％ (P ＜ 0.05) and mean motor function score improved by 30.9％ (P ＜ 0.0l).All bone grafts were healed,without pain,loosening or breakage in the fixation system.Conclusions Posterior pedicular screw fixation attains good short-term outcome for thoracolumbar flexion-distraction fracture combined with posterior ligamentous complex injuries.The surgery provides satisfactory reduction and instant spinal three-column stability for the unstable spine fracture.Sufficient bone graft is the guarantee to permanent stability.

To facilitate noninvasive diagnosis of anemia, high-performance and portable near infrared (NIR) spectrometer for human blood constituents was designed and fabricated based on linear variable filter (LVF).Meanwhile, the performance of support vector regression (SVR) model for quantitative analysis of human hemoglobin (Hb) was investigated.Spectral data were collected noninvasively from 100 volunteers by self-designed LVF-NIR spectrometer, then divided into calibration set, validation set 1 and 2.To establish a robust SVR model, grid search method was applied to optimize the penalty parameter and kernel function parameter c=5.28, g=0.33.Then, Hb levels in the validation 1 and 2 sets were quantitatively analyzed.The results showed that the root mean square error of prediction (RMSEP) were 10.20 g/L and 10.85 g/L, respectively, and the relative RMSEP (R-RMSEP) were 6.85% and 7.48%, respectively.The results indicated that the SVR model had high prediction accuracy to Hb level and adaptability to different samples, and could satisfy the requirements of clinical measurement.Based on the SVR algorithm, the self-designed LVF-NIR spectrometer has a wide application prospect in the field of non-invasive anemia diagnosis.

Aim To investigate the effects of high glu-cose on cholesterol metabolism in renal tubular cells and the intervention of the anthocyanins. Methods HK-2 cells were grown in the DMEM medium supple-mented with 10% FBS and were divided into 5 groups:normal glucose group, high glucose group, mannitol group, C3G group and Cy group. Effect of anthocya-nins on cell viability was detected with MTT, and cho-lesterol accumulation was detected with Amplex Red Cholesterol Assay kit and Filipin staining. Expression of ABCA1 was detected with RT-qPCR and Western Blot. Results In compared with control groups, HG significantly promoted cholesterol mass inside the cell and decreased the cholesterol concentration in the me-dium after treatment for 24 h or 48 h. The levels of mRNA and protein of ABCA1 were detected with RT-qPCR and Western blot, and both were decreased in the presence of HG. Whereas treatment with C3G and Cy markedly attenuated HG-induced cholesterol mass inside the cell by up-regulating the expression of AB-CA1. Conclusions High glucose can reduce the ex-pressions of the ABCA1, and then decrease cholesterol efflux and increase the cholesterol accumulation in HK-2 cells. Anthocyanins can decrease cholesterol accu-mulation by up-regulating the expression of ABCA1.
