Objective To evaluate the effect of transcatheter hepatic artery embolization with lipiodol on perfused radiofrequency ablation (PRFA) on mini-porcine.Methods Ten Chinese mini-porcine were randomly divided into embolization group and control group (each n=5) .A standard PRFA with infusing cooling procedure was done in control group,while transcatheter hepatic artery embolization with lipiodol was done before PRFA in embolization group.CT and MR scan were performed after PRFA.Then a comparative analysis of the shape and volume of the lesions in the liver were performed.Resuits In both two groups,distinct spherical margin of the PRFA lesions was obtained.The minimal diameter was (31.76±3.43) mm in embolization group and (27.23±3.49) mm in control group (t=2.675,P<0.05) .The average volume of the embolization group was (54.47±9.98) cm~3,while in the control group was (20.90±5.68) cm~3 (t=10.424,P<0.05) .Conclusion Transcatheter hepatic artery embolization with lipiodol before PRFA can enlarge the ablation size of mini-porcine's liver.

Objective:The paper aims at developing a method of defining and visualizing the scope of the basic medical insurance pharmacy service, and provides a new way of thinking for the designated pharmacy planning. Methods:Collecting the basic data and information on administrative divisions in the planning area taking equity and efficiency as the guidance, using ArcGIS and its function modules to define and visualize the scope of the medical in-surance pharmacy service. The procedure of issue focus, method improvement, data simulation, expert consultation, methodology perfecting were followed to define and visualize the scope. Results:Forming a whole set of operative pro-cedures of defining and visualizing the scope of the medical insurance pharmacy service based on medical resources allocation standard, and the operation commands and procedures in ArcGIS were clarified. Conclusion:Operating ac-cording to the appropriate method steps, the following can be achieved:(1) The adjacent scope of medical insurance pharmacy service are adjacent to each other but do not overlap or cross;(2) Spatial relations can be clearly and ef-fectively expressed;(3) The shape is flat and regular;(4) The data collected at different times can be comparable in space, providing good prerequisites for medical insurance designated pharmacy planning.
