Background and purpose:The molecular mechanism of the pathogenesis of poorly differentiated gastric carcinoma is unclear, because the key genes related to poorly differentiated gastric carcinoma have not been identified. The study was designed to establish the gene expression profile of poorly differentiated gastric carcinoma, isolate gastric carcinoma-related genes, and investigate the relationship between gastric carcinoma-related genes and gastric carcinoma. Methods:The changes of gene expression profile between poorly differentiated gastric carcinoma and adjacent normal tissue of gastric epithelia were analyzed by cDNA microarray which represented approximately 10 000 known genes that would be tested in the assay. Immunohistochemistry were employed to validate the relationship between gastric carcinoma-related genes and gastric carcinoma.Results:212 genes that were differentially expressed in cancer and non cancerous tissues were identified; 169 genes were highly expressed in cancer tissues by more than 2.0 fold, 43 genes were lower expressed in cancer tissues by more than 2.0 fold. EMS1 protein was located in cytoplasma. The positive rate of EMS1 protein expression was 20% (4/20) in normal gastric mucosa and 89.72% (131/146) in the gastric carcinoma, the difference was significant (P

Objective To investigate the practical value of Shikani optical stylet used for orotracheal intubation in critically conscious patients and to evaluate the successful rate. Method A total of 48 conscious patients with severe respiratory failure were selected from January 2008 to June 2009. Of them, there were 31 males and 17 females,aging 21-86 years old with an average of 57 years old. All enrolled patients needed endotracheal intubation for mechanical ventilation support, and they were assigned to Shikani group (group S, n = 25) and Macintosh group (group M, n = 23) according to the odd and even number of date of admission to this study. The time consumed for intubation, the number of failure in intubation, the adverse effects or complications such as hemodynam-ic changes, injury to the pharyngo-oral cavity, choking and breath-hold were observed and recorded. The rank test and chi-square test were used for statistical analysis. Results The ratio of the successful intubation at first attempt was much higher in group S (96.0%) than that in group M (60.9%) (P <0.01). Compared with group M, the time consumed for intubation was significantly shortened, the cardiovascular reactions were much mild, and the incidence of injury to pharyngo-oral cavity, choking and breath-hold were less in the group S ( P < 0.01 all). Conclusions For the acute and critical patients, especially the conscious ones, orotracheal intubation with the Shikani optical stylet is rapid, successful, safe and less injurious, resulting in mild cardiovascular reactions.

Objective To explore the imaging typing of skull eosinophilic granuloma( SEG) in children,and the clinical significance of this typing system was determined. Methods The clinical and radiological data of 32 cases of SEG confirmed by pathology in the past six years were retrospectively reviewed. According to the imaging findings,which included the size and shape of the granuloma,and the degree of skull destruction,SEGs were divided into four types:typeⅠ( subtle granumoma) ,typeⅡ( exteriorly convex granuloma) ,typeⅢ( biconvex granuloma) and typeⅣ(multiple granulomas and destructions). The imaging features of different types of SEG were analyzed,and the signif-icance of imaging typing was explored combining with the clinical manifestations,treatment programs and prognosis. Results Three cases (9. 4%) were included in typeⅠ,in which,the granuloma was not obvious and the skull destruction was confined in the diploe and outer plate. In type Ⅱ (21 cases,65. 6%),the imaging features included an obvious exteriorly convex mass and complete skull destruction of in-side and outside panels. Granuloma remove and destructed skull repair were performed in all cases,in which 15 were followed up and no re-currence was found. The imaging features of type Ⅲ (5 cases,15. 6%) were biconvex mass which broke through the inner plate and op-pressed the dura and cerebral parenchyma. Therapy program included not only surgical excision of the lesion but also repair of skull and dura. Three cases were followed up and no recurrence was found. Type Ⅳ (3 cases,9. 4%) showed multiple skull destructions and granulomas of various sizes. Chemotherapy and surgery treatment,poor prognosis and ease recurrence were characterized by this type. Conclusion we put forward a imaging typing method for SEGs. This typing system is helpful in guiding clinical protocols and prognosis of SEGs in children.

BACKGROUND:Circumferential pulmonary vein antrum ablations guided by CARTO system or integration of a computed tomographic or magnetic resonance imaging scan (CARTO-Merge) are two main locating methods.Theoretically,CARTO-Merge provides a detailed appreciation of the pulmonary vein anatomy,however,whether it can improve the safety and success of catheter ablation of atrial fibrillation remains uncertainly.OBJECTIVE:To explore the effect of CT image integration into three-dimensional (3D) electroanatomical mapping system on clinical outcomes of catheter ablation of atrial fibrillation.DESIGN,TIME AND SETTING:The randomized contrast observation was performed at Department of Cardiology of Beijing Anzhen Hospital from October 2005 to May 2007.PARTICIPANTS:A total of 93 patients with drugs refractory,paroxysmal atrial fibrillation who underwent circumferential pulmonary vein antrum ablation.METHODS:All patients underwent circumferential pulmonary vein antrum ablation using irdgated radiofreguency ablation with the endpoint of electrical isolation.Ablation was guided by 3D mapping alone in 50 patients (CARTO group) or by CT image integration in 43 patients (CARTO-Merge group).MAIN OUTCOME MEASURES:Procedure-related parameters,such as procedure duration,fluoroscopy duration,cumulative success rate and complication,were compared between the two groups.RESULTS:Pulmonary veins were isolated in all patients.After (12.6±2.9) months follow-up,73 (78.5%) patients did not have recurrence of atrial fibrillation at 3 month after the procedure.The fluoroscopy time in CARTO group was significant longer than that in CARTO-Merge group (P<0.05).The mean procedure duration,radiofrequency ablation duration,procedure-related complication and cumulative success rate were comparable between the 2 groups.CONCLUSION:Circumferential pulmonary vein antrum ablation guided by 3D mapping alone or by CT integration had similar safety and success rate in paroxysmal atrial fibrillation patients.But CT integration,which facilitated to a detailed representation of the anatomy of left atrium,is associated with reduced fluoroscopy duration.
