Chinese Journal of Tissue Engineering Research 2013;(31):5729-5734
BACKGROUND:Spinal canal decompression and fusion combined with pedicle screw fixation has become the main method for the treatment of thoracolumbar fracture and dislocation. OBJECTIVE:To restore the vertebral height of the patients with thoracolumbar fracture and dislocation who underwent subtotal resection and decompression through titanium cage packed with autologous cancel ous bone and pedicle screw fixation. METHODS:Thirty-one patients with thoracolumbar fracture and dislocation treated in the Shanghai 6th People’ s Hospital of Shanghai Jiao Tong University from February 2007 to September 2011 were selected. Al the patients received subtotal resection, spinal canal decompression and titanium cage packed with autologous cancel ous bone and pedicle screw fixation. Imaging examination was performed before and after treatment to observe the recovery of vertebral sequence, vertebral height and Cobb angle, as wel as the recovery of nerve function. RESUTLS AND CONCLUSION:The patients were fol owed-up for 12 months, and al the patients healed wel after treated with titanium cage packed with autologous cancel ous bone and pedicle screw fixation, and there was no loosening, shedding or breakage after pedicle screw fixation. During reexamination, the grafts fusion, good deformity correction, basic recovery of vertebral height and good recovery of Cobb angle were observed. Seven cases had neurological function recovery, and among them, six cases raised for one degree, one case raised for two degrees, and another 22 cases without recovery. Case analysis and relative researches showed that subtotal resection and decompression and titanium cage packed with autologous cancel ous bone and pedicle screw fixation can reduce the loss of correction of the patients with thoracolumbar fracture and dislocation, restore the vertebral height, and enhance the stability of the vertebral body.

7.Effect of serum autoantibodies in the early diagnosis of cancer
Journal of International Oncology 2012;39(6):425-428
At present,the commonly used tumor markers,with low sensitivity and low specificity,can 't achieve the purpose of early diagnosis.However,autoantibodies against tumox-associated antigens have been detected in the asymptomatic stage of cancer and thus can serve as biomarkers for early cancer diagnosis.Moreover,due to autoantibodies are found in sera,they can he screened easily using a noninvasive approach.The discovery of panels of autoantibodies with high sensitivity and specificity will help to improve the diagnostic and prognostic for the patients with cancer.
8.Analysis of allocation and equity of health resources in Changsha between 2007 and 2013
Chinese Journal of Health Policy 2015;(2):76-82
To explore the allocation and equity of health resource in Changsha between 2007 and 2013 and to provide references for government to carry out regional health planning. Method:General statistical analysis was used to describe changes of health resource allocation in Changsha;from the perspective of the population and geography of the nine counties in Changsha, the equality and change of the configuration among doctors, nurses and hospital beds were analyzed by using the Gini coefficient and Theil index. Results:1) The per capita amount of health resources in Changsha increased gradually, and health resources were mainly concentrated in urban areas. 2 ) The Gini coeffi-cients of doctors, nurses and hospital beds was 0. 24~0. 46 according to population distribution between 2007 and 2013 in Changsha, and the Gini coefficient of all health resources by geography was 0. 59~ 0. 79 and peaked in 2009 to then decrease year after year. Following a comparison of the two kinds of regions, the Gini coefficient of urban are-as was significantly higher than that of rural areas, and the Gini coefficient of nurses was the highest among all health resources. 3) Changes in the Theil index were consistent with the Gini coefficient. The difference in the degree of re-source allocation in urban areas exhibited a rising trend, The Theil index was higher than each regional difference. Conclusion:Overall, the equity of allocation of health resources in Changsha between 2007 and 2013 gradually im-proved year by year. The equity of population configuration was greater than that of geographical configuration, and the equity of rural areas was superior to that of urban areas;the equity of the configuration of nurses was poor. The difference between areas is the main factor affecting the equity of Changsha’s health resource allocation.
9.In vivo and in vitro animal models of intervertebral disc degeneration and repair
Chinese Journal of Tissue Engineering Research 2010;14(11):2035-2038
BACKGROUND:Animal models can be used to study specific scientific problems of intervertebral disc biology.Model of disc degeneration is mainly used to resolve the relevant disease mechanisms and scientific and security issues of the treatment.OBJECTIVE:To summarize currently used experimental animal models of intervertebral disc degeneration study,and to dynamically observe and confirm the pathological process of disc degeneration based on disc imaging,morphology,biomechanics and bi(o)chemicel changes.METHODS:Using "intervertebral disc degeneration,animal models,in vivo,in vitro" in English as the search words,Cochrane Library (No.1 2009),Cochrane Library Database of Controlled Clinical Trials (No.1 2009),MEDLINE from 1990 to March 2009,EMbase from 1990 to March 2009,Current Controlled Trials,and the National Research Register were retrieved.Literature was limited to English language.The disc imaging,morphology,biomechanical end biochemical composition and other indicators,as well as the pathological process of disc degeneration served as the evaluation indices.The articles related to the intervertebral disc cell culture models,the whole disc tissue culture model,mechanical model,injury model,biological model,genetically modified models,spontaneous models were included.The repetitive researches and those unrelated to animal models of intervertebral disc degeneration were excluded.RESULTS AND CONCLUSION:The establishment of a reliable animal model can provide favorable conditions for studying the pathogenesis of intervertebral disc degeneration,at the same time,provides a good experimental vehicle for various researches about the repair treatment of intervertebral disc degeneration.Animal models of intervertebral disc degeneration can be divided into two categories:in vitro models and in vivo models of disc degeneration and repair.The former can be assigned into disc cell culture models and whole disc tissue culture model;the latter is assigned into mechanical models,injury models,biological models,genetically modified models,spontaneous models and so on.The above models are commonly used in the study of the occurring mechanism of disc degeneration,as well as the feasibility and effectiveness of a variety of treatments.However,there is still no generally accepted animal models as an ideal disc degeneration model,various types of models reported have their own advantages and disadvantages.

Cancer Research and Clinic 2010;22(7):473-475
Objective To explore the expression of cell apoptosis regulatory elements in esophageal canceration course. Methods 60 specimens of esophageal carcinoma and corresponding adjacent no cancerous tissue were detected quantitatively by propidium iodide(PI) stain and indirect immunofluorescence of fluorescein isothiocyanate(FITC) using flow cytometry(FCM) equipment. Results Expression of bcl-2 and c-FLIP in esophageal carcinoma was significantly higher, and Fadd, Caspase-8 and Caspase-3 were significantly lower than that in adjacent tissues (P <0.01). There was positive correlation between Fadd and Caspase-8 gene (P <0.01 or P <0.05). The expression of Fadd was positively correlated to Caspase-8. Comparing with normal epithelium and dysplasia tissue, DNA content and heteroploid cells were increased significantly in esophageal carcinoma. Conclusion During the esophageal canceration course, expressions of relevant cell apoptosis regulatory elements were abnormal. DNA content and heteroploid cells were increased significantly in esophageal carcinoma.
