1.History and development of spinology
Journal of Integrative Medicine 2003;1(4):304-8, 320
Spinal disease is the injury caused by congenital malformation, degeneration, inflammation and trauma. These injuries lead to structural lesion of spinal itself, intervertebral discs, spinal cord, nerve root and the attachment, and can cause spinal and associated diseases. Spinal diseases include some frequently encountered diseases, as well as some stubborn and serious diseases. These diseases may cause pain of head and neck, shoulder and arm, waist and leg when they are mild, and partial or thorough paralysis when they are serious. In this article, the history, development, foundations and research progress of non-surgical operation of spinal diseases and the developing tendency of modern spinology are introduced.

Objective To map the approximate transcription initiation site of STK11/LKB1 and identify its potential promoter region. Methods All reported transcripts of STK11/LKB1 were colllected through searching online database. The “first exon”, “first intron” and 5' UTR upstream gDNA sequence of STK11/LKB1 were analysed by MethPrimer and FiretEF to predict the CpG island and possible transcription initiation site, respectively. The STK11/LKB1 gDNA sequence was also analysed by softwares such as PromoterInspector to predict the probable promoter region. Results Among all the reported transcripts of STK11/LKB1, 5'UTR of BC007981 was the longest. STK11/LKB1 gene was a typical CpG island associated gene. There was no exon in the upstream region of the “first exon”, and 5'UTR in BC007981 was close to transcription initiation site. Promoters were predicted in the BC007981 5' upstream 200~400bp region. Conclusion The 5'UTR of STK11/LKB1 approaches the transcription initiation site. The transcription initiation site of STK11/LKB1 gene in several hundreds bp region of 5'UTR upstream may be indentified. The data will benefit further research on the trascriptional regulation of STK11/LKB1 through experimental methods.

[Objective]To observe the histomorphology and ultrastructure of the intervertebral disc(I D) in the rat model with cervical vertebral unbalance of dynamic and static force.[Method]Sixty SD rates were randomly divided into 4 groups: 3 months,5 months,7 months and the control group.The cervical I D degeneration model was made by destroying the neck muscle of rats and the tissues wer collected every month.The number,area and thickness of the cartilage end-plate were measured by the means of Miyamoto's Classes.The ultrastructure of the apoptosis cells of the intervertebral disc was observed under the electron microscope.[Result]Compared with the control group,the 3 months group showed degeneratin changes,with disordered structure of the annular fibrosis and thickness increase of calcification layer and decrease of blood vessel unmber in the cartilage layer.Complete fibrosis was found in nucleus pulposus in 5 months model group,with the fibro lamellar structure disappeared and few blood vessel buds.The features of 7 months model group was similar to 5 months and osteophyma had been formed near the bordr of part intervertebal.Under the electron microscope,the number of surface projection and organelles was decreased.Fatty drop and apoptotic body could be seen in disc cells of 3 month model group.Few cells,broken collagen fibers in ECM and more cavitation cells for necrosis in 5 months and 7months model groups could be seen.[Conclusion]The cervical I D of model groups has shown typical morphological changes of degeneration and this trend was more serious with the time passing.In the early and middle stage of degeneration,the apoptosis cells can be seen,but in the terminal stage the cellular necrosis was more common.

OBJECTIVE: To investigate the effects of arc-track private lock pedicle orthopedic fixation system Ⅱ (ALPF Ⅱ) on treatment of spinal diseases. METHODS: A total of 86 patients with spinal diseases were treated using self-made ALPF in the Wendeng Orthopaedic Hospital and were included in this study. Of these patients, 14 suffered from cervical spinal stenosis complicated by cervical vertebral destabilization, 29 from thoracolumbar fractures and dislocations, 15 from lumbar spinal stenosis complicated by lumbar vertebral destabilization, 2 from lumbar spondylolisthesis, 8 from spinal tuberculosis, 6 from ankylosing spondylitis, 9 from idiopathic scoliosis, and 3 from congenital scoliosis. According to conditions, different therapeutic regimens were selected. Postoperatively, regular follow-up was performed to observe vertebral healing, intervertebral height, spinal column sequence, and neurological function recovery. RESULTS: All patients were followed up for 9-30 months (average 12 months). The improvement rate of neurological function, spinal mobility, back pain, and melosalgia was 94.1%, 65.9%, 92.1%, and 87.4%, respectively. The postoperative anterior and posterior vertebral heights were apparently recovered, and kyphotic angle was well corrected. No screw, rod loosening or breakage was found. CONCLUSION: Self-made ALPF Ⅱ is an internal fixation method for treatment of spinal diseases. It provides good reduction, reliable curative effects, less complications, and no biocompatibilities.

Objective To investigate the effects of overexpression of Mash-1 gene on functional recovery and neural differentiation of embryonic stem cells in spinal cord injury mice. Methods CE3 cell line with overexpression of Mash-1 gene was generated with murine stem cell virus. Spinal cord injury model was established with forceps compression in 4-week-old KM mice. Normal saline (model group, n=12), CE3 cells with or without overexpression Mash-1 gene (CE3-Mash-1 and CE3 groups, n=12 respectively) were transplanted into the ar-eas of injury 3 days after injury. They were assessed with the Basso Mouse Scale (BMS) 1, 7, 14, 21, and 28 days after injury. 6 mice from each group were sacrificed 14 and 28 days after injury respectively. The spinal cord area remained were observed with HE stained, and the expression of Oct3/4, nestin,β-tubulin III and glial fibrillary acidic protein (GFAP) were detected with immunofluorescence in the injured spinal cord in the CE3 and CE3-Mash-1 groups. Results The score of BMS significantly improved in CE3 and CE3-Mash-1 groups com-pared with that of the model group (F>84.471, P<0.05), with the more area of spinal cord remained (F>49.990, P<0.05). There were less Oct3/4 positive cells in the CE3-Mash-1 group than CE3 group (t=5.439, P<0.001), with more nestin (t=-7.536, P<0.001) andβ-tubulin III (t=-9.941, P<0.001) positive cells. However, there was no significant difference in GFAP positive cells between CE3-Mash-1 and CE3 groups (t=1.701, P>0.05). Conclusion Overexpression of Mash-1 gene promotes CE3 cells to differentiate into neurons in spinal cord injury mice, and improve the motor function recovery.
