1.Research on spinal cord stimulation for treatment of cerebral ischemia
Journal of Shanghai Jiaotong University(Medical Science) 2009;29(10):1259-1262
Cerebral ischemia is one of the diseases of the central nervous system, which is harmful to the morphology and function of brain cells due to reduced cerebral blood flow. Increasingly more reports have demonstrated that spinal cord stimulation could augment the cerebral blood flow, which is expected to be a potential method for the treatment of cerebral ischemia. In this article, the research progress and related problems of spinal cord stimulation for the treatment of cerebral ischemia are reviewed.

Chinese Journal of Orthopaedic Trauma 2016;18(6):535-538
Objective To investigate the operative outcomes of anatomic and functional reconstruction of the spinal posterior column after resection of intraspinal neoplasms.Methods From January 2010 through October 2014,we treated 32 patients with intraspinal neoplasm in the spine.They were 18 men and 14 women,13 to 62 years of age (average,38 years).The neoplasm was detected in the cervical spine in 10 cases,in the thoracic spine in 14 and in the lumbar spine in 8.All cases received expansive open door laminoplasty via the posterior approach for resection of the intraspinal neoplasm,followed by replantation and titanium plate fixation for anatomic and functional reconstruction of the spinal posterior column.The neural functional recovery,spinal motion and sagittal diameter of the spinal canal before and after operation,spinal stability and graft fusion were observed.Results The patients were followed up for 3 to 23 months (average,13 months).All the intraspinal neoplasms were completely resected.The Frankel grading of neural functional recovery was improved differently in all the cases.By the final follow-ups,the spinal motion was normal in all the cases,without any significant limitation.Graft fusion and rigid internal fixation were achieved in all the cases.Short-term follow-ups revealed no signs of spondylolisthesis or spinal instability.At the final follow-ups,the 3-D CT reconstruction showed no significant shortening in the sagittal diameter of the same spinal canal before and after operation (P >0.05).Conclusions For intraspinal neoplasm in the spine,the whole vertebral lamina is opened or removed via the posterior approach to resect the neoplasm,followed by reduction of the vertebral lamina and mini titanium plate fixation to reconstruct the anatomy and function of the original spine.This is an ideal way to treat intraspinal neoplasms in the spine.
4.SOX1 and tumor
Journal of International Oncology 2013;40(8):566-569
SOX1,a member of the SOX transcript factor super family,has been demonstrated having the functions of regulating the development of human embryonic neural system and crystalline lens,and the additional function of SOX1 in tumors are attracting more and more attention as well.It is reported in resent years that SOX1 is detected lowly expressed in many kinds of tumor issues,which owns to the methylation of SOX1.SOX1 can also regulate the abilities of tumors on proliferation,invasion and migration.Besides,SOX1 may play a crucial role in regulation of the differentiation of cancer stem cells.Further research of SOX1 and its function among related pathways may contribute to seeking for new therapies for tumor treatment.

Stroke is characterized by a group of acute cerebral vascular diseases which attack acutely with focal neurological deficits. Residual motor deficits often sojourn after stroke. Cortical stimulation, which is a technique developed many decades ago, has recently re-emerged as a promising method for researchers in their quest to causally probe cortical representations of sensorimotor and cognitive functions and to facilitate the treatment of various neuropsychiatric disorders. The article summarizes the research progress of cortical stimulation in the promotion of motor function recovery after stroke, the method of operation, the possible mechanisms and the prospect.

Objective To observe the effect of atropine mydriasis, wearing myopia glasses for short or long distance, and massage on preventing and controlling myopia in teenagers and children. Methods A total of 198 myopia cases (involving 393 eyes) were randomized into control group and treatment group. The control group was given eyesight examination after mydriasis with atropine sulfate eye gel and wearing myopia glasses for long distance. The treatment group was given eyesight examination after mydriasis with atropine sulfate eye gel, wearing myopia glasses for short distance, and massage therapy. Eyesight examination was carried out once every 2 months and lasted for one continuous year. The changes of diopter were compared between the two groups. Results ( 1) Of 194 affected eyes from the treatment group, 96 eyes were effective, 68 were stabilized, and the effective rate was 45.5%and stabilizing rate was 35.1%. Of 199 affected eyes from the control group, 3 eyes were effective, 9 were stabilized, and the effective rate was 1.5%and stabilizing rate was 4.5%. The differences of effective and stabilizing rates were significant between the two groups ( P<0.01). ( 2) After treatment, the myopia diopter was increased in the control group ( P<0.01 compared with that before treatment) , and the myopia diopter in the treatment group maintained stable ( P>0.05). The difference of diopter was significant between the two groups (P<0.01). (3) The difference of astigmatism was insignificant in both groups before and after treatment and between the two groups after treatment (P>0.05). Conclusion Mydriasis with atropine sulfate eye gel, wearing myopia glasses for short or long distance, and focal massage therapy show certain preventive effect on myopia in teenagers and children by controlling the development of myopia diopter.

The target therapeutic agents of HER-2 extracellular ligand-binding domain have become the core of breast cancer research. A small peptide molecule and an anti-HER2 extracellular domain monoclonal antibody conjugated with protein toxins, radioisotopes, and chemotherapeutic drugs (immunoconjugate) can improve efficacy and reduce systemic toxicity. Vaccines based on HER-2 extracellular region should protect patients from HER-2-overexpressing breast cancer growth. In this review, studies on targeted-block therapies of the HER-2 extracellular ligand-binding domain in breast cancer were discussed to provide references for clinical applications.

OBJECTIVE:
In this study, we have detected the expression of STC2 protein in laryngeal cancer and The safe incisal margin by immunohistochemical staining, to evaluate its correlation with clinical features and the prognosis value in laryngeal squamous cell cancer.
METHOD:
Eighty-one paraffin-embedd specimens of patients who underwent surgery for laryngeal cancer were collected. Clinical data, including date of birth, gender, tumor subsite, tumor stage, RT, and survival status have been recorded. The samples including laryngeal cancer tissues and the safe incisal margin were analyzed for the expression of STC2 protein by immunohistochemical staining. We analyzed the correlations with STC2 expression level and clinical data with software SPSS 18. 0.
RESULT:
(1)fifty-six cases in 81 cases (69. 1 %) are positive. In 30 cases of the safe incisal margin tissues, STC2 is not expressed, which shows statistically significant differences between the two groups (P<0. 05). (2)Overexpression of STC2 in laryngeal cancer were correlated with the tumor clinical stage and N stage, T stage, tumor site location and histological grade (P<0. 05), but not with genderor age (P> 0. 05). (3)The result showed that the 3-year survival rate is 74. 1%, according to the survival analysis by STC2, STC2 positive group has poorer outcome versus the negative group. (4)The clinical stage displayed the independent value in predicting the tumor prognosis of laryngeal cancer (P<0. 05), not the expression level of STC2.
CONCLUSION
Overexpression of STC2 in laryngeal cancer patients is correlated with poor outcome, which means STC2 positive group has poorer prognosis than the STC2 negative group.
