The paper introduces an overview of Shanghai medical security system, analyzes its effectiveness and challenges, and put forward overall goals and key tasks in the future. Shanghai has formed a multiple, medical security system and basically achieved the short-term goal of medical security system establishment which was requested to put forward in national health system reform. Shanghai medical insurance system has played a positive role in promoting economic and social development and reducing the burden of medical expenses. To further implement requirements of national health system reform, Shanghai will be conducting the integration of different schemes , narrow down the gap of benefit packages, improvement of health care management and the initiatives of nursing care insurance to further improve the medical security system, and strive to cover 98% of household population and 90% resident population in 2012.

Objective To determine the prognosis and staging non small cell lung cancer (NSCLC) that extends across the fissure into adjacent lobe after surgery.Methods 3752 patients with histopathologically confirmed non small cell lung cancer (NSCLC) received surgical reeessetion from January,1997 to April,2007.Among them,163 patients have a tumor invasion beyond fissure.After matching by pathologic TNM staging (7th),326 patients whose tumor defined in a single lobe were eligible for analysis.Results Histopatholngic staging of matched patients was I a:10 patiens(6.1％ ),I b:79 patients (48.5％),Ⅱa:5 patients (3.1％ ),111:44 patients (27.0％) and Ⅲa:25 patients( 15.3％ ).5 years survival in patients with stage 1 tumors crossing the interlobar fissure was 51％,while in patients not cross the interlobar fissure was 63％ ( P ＜0.05 ).There was no difference in survival for tumors stage Ⅱa and above with regard to importance of interlobar extension.The T2 tumor extending across a lung fissure had a reduction in survival compared with T2 tumor not cross the lung fissure and similar to the T3 tumor without the fissure invasion.Conclusion Our results suggest that TNM staging should be modified for tumor extends the fissure into adjacent lobe.
