Although the development of diagnosis and treatment about degenerative scoliosis has improved significantly,it still remains controversial about how to select appropriate surgical methods.The goal of this review is to raise awareness and stimulate attention on the correlation between clinical manifestation and spinal deformity,which is one of the key factors to affect the surgical outcomes on the opinion of more and more researchers in the past 20 years.When an adult spinal deformity is not the source of symptoms and the clinical symptom is outside of curve,symptomatic relief may be provided through limited decompression.If thoroughly decompression,it will be enough to combine with short segment fixation.However,while an adult deformity is the source of symptoms and the clinical symptoms is within the curve,the options are typically limited decompression on the basis of good stability,otherwise,it will be the only consideration of decompression combined with long segment fixation.

[Objective]To observe the characteristic ultrastructure changes of compressive spinal cord injury.[Method]Animal model of compressive spinal cord injury was made by modified Allen's method.Pathological changes of spinal cord tissues were observed with transmission electronic microscopy after 4 weeks.[Result]The characteristic ultrastructure changes of compressive spinal cord injury were observed obviously.It was necrosis without inflammatory cell reaction.The single-direction break of myelin sheath and the traumatic cell could be observed.They were all formed by the reason of biomechanics.These two characters were the characteristic ultrastructure changes of compressive spinal cord injury.[Conclusion]These new ultrastructure observations can provide certain materials for the basal explore of compressive spinal cord injury.

Ohiective To establish an in vitro test system for testing CMV specific immune response. Methods Human embryonic lung fibroblasts(HELF)infected with CMV-AD169 and a mutant strain RV-TB40E-4, respectively, were stained with anti-HLA-A * 0201-PE and then measured for the expression of HLA-A * 0201. The infected HELF were incubated with individual pp65 peptide NLVPMVATV and cultured together with PBMC,then intracellular IFN-γ was tested by flow cytometry(FCM). Results The expression of HLA-A * 0201 was markedly suppressed on AD169-infected fibroblasts, while it was not affected on RV-TB40E-4-infected cells. PBMC showing no response to AD169-infected cells responded significantly to RV-TB40E-4-infected cells. The HELF infected with AD169 and loaded with external peptides induced a significantly stronger response which was the sum of the induced response ratios of the infected HELF and the uninfected HELF loaded with peptides. Conclusion CMV-AD169 downregulates the expression of MHC Ⅰ, while it does not decrease the capacity of cells to present external peptides. RV-TB40E-4,a CMV mutant in which the gene of US2-6/US11 has been deleted, does not affect MHC Ⅰ expression, and therefore represents a more suitable tool to explore CMV-specific immune response.

Endostatin is an antitumor molecular targeting angiogenesis of tumor and plays an inhibitory role in tumorigenesis through inhibiting pathological angiogenesis, proliferation and metastasis of tumor. As increasing drugs for targeting therapy aim in clinic, endostatin has become one of hot spots of research on combined treatment of cancer in recent years.

Objective To investigate distribution of integrain ?1 in human oocytes and embryos before and after maturation/fertilization,dring the first and second meiosis,in morulae and blastocyst stage. Methods Human oocytes and embryos were stained by anti-integrin ?1 (PharMingen 09351D) and FITC-labeled second antibody (PharMingen 110094D),and observed by confocal microscope. Results Integrin ?1 concentrated in the nuclear area in matured oocytes,zygotes and 2-cell stage embryo,indicating that integrin ?1 might involve in mitosis.Dislike mouse,there was no distribution of integrin ?1 on the well-accepted sperm binding area on the oocytes,indicating that integrin ?1 might not involve in the binding and fusion of human sperm to human oocytes.Conclusion It was first postulated that integrin ?1 might actively involve in the pronuclear fusion process in human in vitro fertilized oocytes.The marker of ectotrophoblasts,polarized distribution of integrin ?1, appeared at the morulae stage.The stronger expression in ectotrophoblasts around the inner cell mass might indicate some specific function of the ectotrophoblasts near the ICM.

BACKGROUND:In recent years, the researchers have studied the adjacent segment degeneration after cervical fusion. Several studies concerned the adjacent segment degeneration after anterior cervical corpectomy and fusion.
OBJECTIVE:To evaluate the correlative factors of adjacent segment degeneration after anterior cervical corpectomy and fusion.
METHODS:122 patients were included in the study from 126 patients who underwent anterior cervical corpectomy and fusion that operated by the same treatment team and involved a single vertebral body and the two plates between February 2009 and February 2012. The final fol ow-up period was 3 years. According to the degeneration progress of adjacent segment degeneration, these patients were divided into non-progression group and progression group. The gender, age, preoperative adjacent segment degeneration, cervical range of motion, upper and lower vertebral range of motion, surgical segment, titanium mesh subsidence, plate-to-disc distance, and cervical curvature index were compared between two groups. Logistic regression analysis was applied to analyze the correlative factors of adjacent segment degeneration.
RESULTS AND CONCLUSION:(1) There were significant differences in preoperative adjacent segment degeneration, postoperative cervical range of motion, postoperative upper and lower vertebral range of motion, and postoperative cervical curvature index (P<0.05), which were included in logistic regression analysis. (2) Logistic regression analysis regression model:adjacent segment degeneration=0.317× postoperative cervical range of motion+3.374×preoperative adjacent segment degeneration+1.862 × postoperative lower vertebral range of motion-0.795×postoperative cervical curvature index-16.481. Logistic regression analysis demonstrated that preoperative range of motion, postoperative cervical range of motion, postoperative lower vertebral range of motion and postoperative cervical curvature index were correlative factors of range of motion after adjacent segment degeneration (P<0.05). (3) These results indicated that preoperative adjacent segment degeneration, postoperative cervical range of motion, postoperative lower vertebral range of motion and postoperative cervical curvature index were correlative factors of adjacent segment degeneration. We should actively carry out effective measures to prevent the progress of the adjacent segment degeneration before, during and after anterior cervical corpectomy and fusion.

Objective To explore effect of increasing cerebrospinal fluid (CSF) leptin level by administration from the foramen magnum to the cerebellum medulla oblongata pool in osteoporosis in rabbit model established by ovariectomy (OVX) and methylprednisolones.Methods According to certain inclusion and exclusion criteria,30 adult rabbits which were healthy 5-month-old female New Zealand white rabbits with the same batch and weight were divided into 5 groups (n=6) with random number table,including control group,normal saline group,Low dose group,middle dose group and high dose group.The animal model of osteoporosis (OP) was established 8 weeks after ovariectomy (bilateral ovarian resection) and intramuscular injection of methylprednisolone daily for 8 consecutive weeks in all groups.The control group were only simulated puncture and didn't inject any drugs or normal saline,the normal saline group were intracerebroventricular (ICV) injection with NS and Low,Middle and High dose group injected with low,middle and high dose of leptin respectively at 0,3,7 days after OVX.Before (0 week) and 4,8 weeks after the operation,the measure of dual energy X-ray absorptiometry was done on all the rabbits femur and bone mineral density (BMD) was delivered.Before (0 week) and 4,8 weeks after the first administration,leptin in cerebrospinal fluid (CSF) and serum growth hormone (GH),insulin growth factor 1 (IGF-1) and osteocalcin (OT/BGP) were tested with Enzyme linked immunosorbent assay and serum calcium,phosphorus and alkaline phosphatase (ALP) with automatic biochemical analyzer (ACA).The rabbits were sacrificed and the thalamus and femoral neck were harvested to test the expression of leptin receptor (LEPR) in thalamus and bone morphogenetic protein-2 (BMP-2) and type Ⅰ collagen (Col Ⅰ) at 8 weeks after the first administration.Results Compared with the control group and NS group,the cerebrospinal fluid (CSF) leptin concentration of leptin administration groups kept in a higher level significantly at 4 and 8 weeks after leptin administration,it was positively correlated with the concentration of administration.After administration 4 and 8 weeks,the bone mineral density (BMD) of leptin administration groups were not significantly lower than that of non-administration groups,and the high dose group was unchanged.The serum osteocalcin/bone glad protein (OT/BGP) concentration of leptin administration groups decreased more significantly compared with the non-administration groups at 4 weeks after leptin administration;and it rebounded more significantly than the non-administration groups and low dose group rebounded more significantly than other non-administration groups at 8 weeks.The concentration of serum growth hormone (GH) of 5 groups showed a downward trend at 4 and 8 weeks,the serum GH concentration of leptin administration groups decreased more significantly than the non-administration groups.The concentration of serum insulin-like growth IGF-1 of 5 groups were decreased significantly at 4 weeks,and the serum IGF-1 concentration of control and low dose groups were significantly higher than other 3 groups at 8weeks.Compared with the non-administration groups,the concentration of serum Calcium of leptin administration groups were increased more obvious,and it was positively correlated with the concentration of administration.Serum phosphorus of 5 groups were decreased at 4 weeks and elevated at 8 weeks;there was no difference among the groups.Serum ALP showed a continuous downward trend,and the middle dose group decreased significantly compared with other groups at 4 and 8 weeks.RTPCR results showed that the BMP-2 and Col Ⅰ mRNA expression increased and positively correlated with leptin administration concentration at 8weeks.Conclusion The increase of cerebrospinal fluid leptin level can promote the bone metabolism,reduce bone loss and precaution the occurrence of osteoporosis in rabbit model caused by OVX and methylprednisolone,and it was positively correlated with the concentration of administration.That provides a new method for the prevention and treatment of osteoporosis in rabbit model.

Objective To investigate the enhanced osteogenesis during bone fracture healing after intracerebroven-tricular (ICV) leptin injection, using rabbit model with created segmental bone defect in right tibial. Method Segmental critical-sized defects were created at the right tibial bone of skeletally mature New Zealand white rabbits. In experiment group (leptin group), recombinant rabbit leptin was injected into cerebellomedullary cistern through foramen magnum. While in control group, normal saline was injected in the same way. Bone Mineral Density (BMD) was evaluated by qCT at 1st, 3rd, 7th, 14th and the 21st days. At the 21st days, all rabbits were euthanized to collect the right tibia for histomorphology, to ex-amine the BMP-2 expression in the bone callus by Fluorescence in situ hybridization (FISH). Result In the leptin group, body weight declined more obviously than control group then it start to arise at the 14th day;qCT showed significant higher BMD in leptin group than in control group at the 7th day;FISH showed a higher BMP-2 expression in leptin group than in control group. Conclusion Cerebellomedullary leptin injection through foramen magnum could accelerate limb fracture healing in rabbit model with right tibial bone defection.
