Significance of vulnerability assessment in establishment of Hainan provincal disaster medical system

Hainan is an island province in south China with a high frequency of unconventional emergencies due to its special geographic location and national military defense role. Given the limited transportation route from Hainan to the outside world, self-rescue is more important to Hainan Province than other provinces in China and it is therefore imperative to establish an independent, scientific as well as efficient provincal disaster medical system in Hainan. The regulatory role for vulnerability analysis/assessment has been demonstrated in establisment of disaster medical system in varoius countries and or regions. In this paper, we attempt to describe/propose how to adopt vulnerability assessment through mathematical modeling of major biophysical social vulnerability factors to establish an independent, scientific, effieicnt and comprehensive provincial disaster medical system in Hainan.

Inhibitory effects of argatroban on instant blood-mediated inflammatory reaction after islet transplantation in vitro / 中华器官移植杂志

Objective To investigate the inhibitory effects of Argatroban on the instant bloodmediated inflammatory reaction(IBMIR)after islet transplantation.Methods Rat islets were isolated and purified rat islets,and were divided into blank control group,control group and experimental group.In the control group,the blood and the islets were directly mixed,and in the experimental group the Argatroban was added to the mixture based on the control group.while the blank control group was added with blood alone without the islets.Each group was reacted at 37℃for 60min,and then the content was filtered through trap valve of 70 μm.The residual thrombus and tissues were filtered by the trap valve in both the experimental and control groups,detected by the thinprep cytologic test(TCT),and the filtrate received blood routine test,and the function of islet was determined using insulin releasing test.Results The number of blood platelets,white blood cells,mononuclear cells,and lymphocytes percentage in the experimental group were significantly higher than in the control group after 60 min(P＜0.05).Under the environment of the high and low concentrations of glucose,the insulin release in experimental group was significantly increased as compared with the control group,and the insulin release index of former was 2.25±0.18,significantly higher than that of the latter 3.36±0.18(P＜0.05).The residual thrombus and tissues had few islet cells in the control group,the structure was damaged seriously,the capsule was not intact,and there were a large mumber of micro-thrombosis around the islets formed by red blood cells.But there were a large number of islet cells in the experimental group.the structure was intact in a mass,and no obvious micro-thrombosis around the islets was found.Conclusion Argatroban can effectively inhibit IBMIR in vitro,and alleviate the damage to the islet cells.
