Antiangiogenesis therapy is one of the most common anticancer therapies. Bevacizumab is a monoclonal antibody that blocks the binding of the vascular endothelial growth factor to its high-affinity receptors. It is the only antiangiogenic agent approved for the first-line treatment of advanced non-small cell lung cancer (NSCLC). Many recent studies have attempted to determine the suit-able partners of bevacizumab in first-line treatment of NSCLC and evaluate its efficacy and safety as a second-line or beyond and con-tinuous treatment of beyond disease progression in patients with advanced NSCLC. This review summarizes current clinical research about the efficacy and safety of bevacizumab in the treatment of advanced NSCLC.

OBJECTIVE:To reflect the representative problems existing in the medication safety of public from the side,and provide reference for conducting the following public survey in a large area. METHODS:Questionnaires were used to investigate the knowledge of drug and medication habits of teachers in a senior high school in Beijing,and the received data was statistically analyzed. RESULTS:Totally 88 questionnaires were issued in this investigation,84 effective questionnaires were acquired,with ef-fective recovery of 95.45%. A few teachers had blind faith in intravenous infusion and preferred using antibiotics without doctor's di-agnosis when they caught a cold and fever;48.81%of the respondents barely understood or only partly understood the drug instruc-tions;34.52% didn't know that more serious adverse reactions induce by intravenous infusion were more serious than by oral treat-ment;46.43% rarely checked the period of validity of reserved drugs at home;38.10% didn’t following directions when taking drugs;80.95% had never received the education of medication safety,and 21.43% of them had no intention to accept this educa-tion;when taking drugs for a long time,79.76% of them didn’t do regular examinations of blood routine,renal and liver function tests. CONCLUSIONS:The knowledge of drug use of the respondents in the school is poor,there are many misunderstandings ex-isted in the medication habit,which prompts hidden trouble also exists in medication safety,and reflects hidden trouble commonly exists in medication safety for public from the side.

As an income redistribution mechanism, the design of Urban Resident Basic Medical Insurance ( URBMI) should reflect the inclination to take care of vulnerable populations, such as people with chronic diseases and low incomes. Therefore, whether the healthcare services of vulnerable populations have been improved, is the most important indicator to determine the effectiveness of the URBMI. Using the DID model, this paper analyzes healthcare service utilization of invulnerable and vulnerable populations before and after the establishment of URBMI ( including both outpatient and inpatient) , based on the idea that these two populations have different socio-economic and health status. Then, based on the gap between the healthcare service utilization changes of different groups, we can measure the equity in URBMI. The results show that the establishment and implementation of URBMI has indeed narrowed the gap of invulnerable and vulnerable populations with different socio-economic and health status; health-care service utilization of vulnerable populations has increased significantly, and health status has significantly im-proved. From vertical and horizontal perspectives, the results prove that the establishment of URBMI has improved the equity of healthcare service utilization among different populations across China.
