AIM: To study the effects of cortactin on the tumor biology of SGC-7901 cells and identify the mechanism involved in the process. METHODS: Cell lines in which cortactin was stably overexpressed or knocked down as well as the respective control cell lines were established by standard molecular methods. The effects of cortactin on the proliferation, migration and invasion capacity of SGC-7901 cells were assessed by the MTT assay, colony formation, flow cytometry, transwell migration and matrigel invasion. Nude mouse models were also used to assess the role of cortactin in the growth and metastasis of SGC-7901 cells in vivo. Western blotting analysis was performed to detect the expression of epidermal growth factor receptor (EGFR) and downstream molecules. RESULTS: Cell lines in which cortactin was stably overexpressed or knocked down as well as control cell lines were successfully established and designated as LV5-cortactin-SGC, LV5-SGC, LV3-shRNA-SGC and LV3SGC. Cortactin overexpression promoted SGC-7901 cell migration (340.7 +/- 12.6 vs 229.1 +/- 23.2, P < 0.01) and invasion (71.6 +/- 5.2 vs 48.4 +/- 3.6, P < 0.01). Cortactin downregulation impaired SGC-7901 cell migration (136.2 +/- 19.8 vs 225 +/- 17) and invasion (29.2 +/- 5.2 vs 49.6 +/- 3.8, P < 0.01). The results from the MTT and colony formation assays results indicated increased LV5-cortactin-SGC cell proliferation and decreased LV3shRNA-SGC cell proliferation compared to the control cells. Flow cytometry analysis demonstrated that cortactin overexpression promoted the proliferation index of SGC-7901 cells, and the results were reversed when cortactin was downregulated. Mouse tumor models confirmed that cortactin expression increased SGC-7901 cell proliferation and metastasis in vivo. Western blotting analysis revealed that cortactin elevated EGFR expression and activated the downstream molecules. CONCLUSION: Cortactin expression promoted the migration, invasion and proliferation of SGC-7901 cells both in vivo and in vitro. The EGFR signaling pathway is mechanistically involved.

INTRODUCTION Sleep disturbance is one of the most common nonmotor symptoms in Parkinson's disease (PD).Sleep disturbance affects 40-98% of PD patients in the world. In China, the prevalence of PD patients with sleep disturbance ranges from 47.66% to 89.10%. Sleep disturbance usually has adverse impact on the quality of life of PD patients. Apossible pathogenesis of PD with sleep disturbance include thalamocortical pathway degeneration and changes of neurotransmitter systems. The etiology of sleep disturbance is multifactorial,involving degeneration of areas regulating sleep,sleep structure affected by drugs,sleep disturbance induced by drug,and sleep fragmentation by multiple factors. 展开更多

Objective:To investigate the clinical value of a minimally-invasive treatment of communicating hydrocephalus using a percutaneous lumboperitoneal (LP) shunt.Method:The clinical and long-term follow-up data of 256 patients suffering from communicating hydrocephalus and undergoing percutaneous LP shunt during 1998 to 2008 were retrospectively analyzed.Results:After the follow-up,which lasted 6 months to 10 years,219 cases of communicating hydrocephalus recovered well (ventricular size returned to normal and symptoms completely disappeared),25 cases were brought under control (ventricle size reduced by 50% and symptoms partially abated),and 12 cases showed no obvious changes.Fifteen obese subjects needed modifications of the shunt due to the obstruction of the abdominal end following wrapping,and one subject underwent extubation as the subject was unable to tolerate stimulation of the cauda equina.The effectiveness of shunting was 91.40% and the probability of shunt-tube obstruction,which occurs predominantly in the abdominal end,was only 5.85%,far lower than that of ventriculoperitoneal (VP) shunt.Three subjects had a history of infection following VP shunting.Conclusion:LP shunting is minimally invasive and effective in treating communicating hydrocephalus,with fewer complications. 展开更多

INTRODUCTION Fatal familial insomnia (FFI) is a serious and rare prion disease, which was first reported by Lugaresi et al. in 1986.Early diagnosis of FFI might be important for early and sufficient counseling of patients and their relatives, also concerning the risk of inheritance, and potentially also for treatment studies. However, the diagnosis of FFI might be difficult because of the heterogeneity of clinical features, low sensitivity of diagnostic tests, and absence of family history. The aim of the present study was to develop a clinical scheme and diagnostic criteria for FFI based on our research and expert consensus. 展开更多

Shanghai “12.31” stampede was a preventable tragedy that the government and event planner hold responsibility for. At the same time, it can be a legacy for improvement in the future. The government should draw experience on the implementation of an emergency preparedness system, in order to improve the rapid emergency response during mass gatherings in the future. 展开更多
