Abstract: A method for avoiding resource being released mistakenly during tracking area update or handover process comprising: determining, by a target Mobility Management Entity MME, whether to use an old System Architecture Evolution Serving GW or to reselect a new Serving GW; if the target MME determines to select a new serving GW, notifying the original MME, the original MME sending a request for deleting bearer to the old Serving GW. The technical scheme of the present invention can avoid that the original MME will still send a request for deleting subscriber context to the old Serving GW when the target MME still uses the old Serving GW rather than selects a new one during tracking area update or handover process of the subscriber, which results in the appearance of a problem that the resource related to the subscriber in the old Serving GW is released mistakenly.

Abstract: Novel dual-targeted, bifunctional anti-influenza drugs formed by conjugation with anti-inflammatory agents are disclosed. Exemplary drugs according to the invention include caffeic acid (CA)-bearing zanamivir (ZA) conjugates ZA-7-CA (1), ZA-7-CA-amide (7) and ZA-7-Nap (43) for simultaneous inhibition of influenza virus neuraminidase and suppression of proinflammatory cytokines.

The synthetic bifunctional ZA conjugates act synergistically towards protection of mice lethally infected by H1N1 or H5N1 influenza viruses. The efficacy of ZA-7-CA, ZA-7-CA-amide and ZA-7-Nap conjugates is much greater than the combination therapy of ZA with anti-inflammatory agents.
