Background and purpose: The prognosis of completely resected stage ⅢA(N2) non-small cell lung cancer (NSCLC) remains a significant concern. The 5-year overall survival (OS) rates range from 10% to 30%. This study aimed to analyze the patterns of first failure in completely resected stage ⅢA(N2) NSCLC and to assess the actuarial risk of developing metastasis at different sites and to guild standard clinical practice. Methods: Patients withⅢA(N2) NSCLC who had undergone radical surgery in our hospital from Jan. 2005 to Jul. 2012 were retrospectively reviewed. The progression-free survival (PFS), the OS, patterns of first failure, the actuarial risk were analyzed. The cumulative incidence of first failure was determined using the Kaplan-Meier analysis. Results: Among 357 patients who met the eligibility criteria with completely resected stage ⅢA(N2) NSCLC, 5-year OS was 36.9%. There were 284 (77.6%) patients experiencing disease failure: 61 with local failure, 197 with local and distant failures, and 26 patients with local recurrence as the first failure. Brain, bone and lung were the main sites of distant failure as the first failure, while brain was the most common site. There were 67 patients developing brain metastases (BM) as the first site of failure. The median time of local failure as the first site of failure was 13.6 months, and the time to develop distant recurrence was 15.1 months. 92.5% BM developed in 3 years after the complete resection. Conclusion: As the first failure, the rate of distant failure was much higher than that of local failure in completely resected stage ⅢA(N2) NSCLC. Brain was the most common site of distant failure as the first failure. These results can be helpful in guiding standard clinical practice and evaluating the outcome of comprehensive treatment.

It is to difficult to diagnose and treat hepatobiliary surgical diseases since its diverse clinical manifestations,which increases the difficulty of clinical internship.Taking clinical cases as teaching material,case-based learning was combined with teaching theme and was conducted by means of discussion and question and answer between teachers and students.Students can know about concepts or theories related to teaching theme.Case-based learning in internship can consolidate basic knowledge of hepatobiliary surgery,cultivate clinical scientific thinking and is helpful in analyzing and resolving problems of hepatobiliary surgical diseases.

Objective To explore the feasibility of using clinical whole body MR scanners to investigate the intravital visibility of central nervous system (CNS) lesions in rats of multiple sclerosis (MS). Methods Ten Lewis rats were injected with the peptide 35-55 of myelin oligodendrocyte glycoprotein to make the model of MS. On a Siemens Sonata 1.5T MR scanner equipped with a flexible surface coil, rats brain and spinal cord were examined using T2-weighted and T1-weighted imaging with slice thickness of 1-2 mm. On a Siemens Trio Tim 3.0T MR-scanner equipped with a quadrature wrist coil, rats were examined using T2WI, T1WI and Gd-DTPA enhanced T1WI 3-dimensional imaging with voxel size up to 0.06-0.08 mm~3. Rat brain and spinal cord images in multiple orientations were reconstituted with special software in workstation. Results T2WI and T1WI of the lesions in MS rat brain with high spatial and contrast resolution could be obtained with clinical 3.0T MR scanner, though the image resolution of spinal cord was relatively low. The resolution of 1.5T MR was lower than that of 3.0T. Plaques in CNS of MS rats presented as hyperintense areas on T2WI and hypointense areas on T1WI. Contrast enhancement was observed as hyperintense on T1WI. Conclusion High quality images of CNS lesions canbe obtained with clinical 3.0T MR-scanner in MS rat, which offers a noninvasive access for studying CNS diseases in the rats.
