Radiofrequency ablation therapy not only causes the necrosis of localized tumor cells,but also produces immunogenic tumor associated antigens and a large number of inflammatory cytokines and a variety of immunogenic mediums,which promotes the local infiltration and activation of immune cells and stimulates the immune system to produce certain anti-tumor effect.But the intensity of anti-tumor effect is feeble and is insufficient to inhibit the growth of tumor cells.Radiofrequency ablation therapy combined with special immunotherapies,such as immune stimulants,adoptive immunity cells therapy,dendritic cell vaccines,monoclonal antibodies and so on,can maximize the clinical benefit,which is a good pattern about tumor comprehensive treatment containing immunotherapy.

Analysis of setbacks found in the existing system and mechanism of public hospitals. Based on the health reform principles of Separation of administration and management, Separation of administration and operation, Separation of prescribing and dispensing, and Separation of for-profit hospitals and nonprofit hospitals, the authors named the following roadmap for public hospital governance reform. First, set up a management committee for each public hospital to coordinate the government function for medical service; set up a public hospital authority to upgrade the management level of these hospitals; transform functionality of health authorities to encourage diversity in medical service providers. Second, establish the tiered decision making mechanism, autonomous operation system and diversified supervision system, to separate administration and management. Third, formulate articles of association for hospitals to encourage their evolution to legal entities, consolidating the government reforms by legal means.
