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.

OBJECTIVE:To explore losses and gains (L&G) and L&G ratio induced by Essential Medicine System in a county. METHODS:By choosing a county in western China as sample area,field investigation was used to collect outpatient and inpatient visits,outpatient and inpatient income,drug income,total length of stay and medical insurance reimbursement criteria in primary medical institutions (township health centers,village health rooms) of the county during 2009-2015. By setting the year 2009 as the baseline year,the drug cost reimbursed by medical insurance was simulated and calculated when Essential Medicine System were not implemented;L&G and L&G ratio of medical insurance were calculated by comparing with actual drug cost reimbursed by medical insurance. RESULTS:The year 2012,in which the sample county fully implemented the Essential Medicine System was the turning year. Medical insurance funds lost in primary medical institutions of the county during 2010-2011(lost 437000,915000 yuan,respectively),but gained during 2012 to 2015(gained 199000,494000,858000,1290000 yuan, respectively);the L&G ratio increased from -0.67% to 1.21%. For reimbursed outpatient drug cost and inpatient cost,L&G of medical insurance were different. For reimbursed drug cost of village health room and township health center,L&G of medical insurance were also different. CONCLUSIONS:The implementation of Essential Medicine System benefits to medical insurance within the county and Medical insurance funds can be saved.

OBJECTIVE:
To investigate the effects of blocking the activation of ERK pathway on the expression of matrix metalloproteinase-9 (MMP-9) and the formation of cerebral edema in SD rats after brain injury.
METHODS:
Ninety SD rats were randomly divided into 3 equal groups, including a sham-operated group, modified Feeney's traumatic brain injury model group, and ERK inhibition group where the ERK inhibitor SCH772984 (500 μg/kg) was injected via the femoral vein 15 min before brain trauma. At 2 h and 2 days after brain trauma, the permeability of blood-brain barrier was assessed by Evans blue method, the water content of the brain tissue was determined, and the phosphorylation level of ERK and the expression level of MMP-9 mRNA and protein were measured by RT-PCR and Western blotting.
RESULTS:
Compared with the sham-operated group, the rats with brain trauma exhibited significantly increased level of ERK phosphorylation at 2 h and significantly increased expression of MMP-9 mRNA and protein 2 days after the injury ( < 0.01). Treatment with the ERK inhibitor significantly decreased the phosphorylation level of ERK after the injury ( < 0.01), suppressed over-expression of MMP-9 mRNA and protein 2 days after the injury ( < 0.01). The permeability of blood-brain barrier increased significantly 2 h after brain trauma ( < 0.05) and increased further at 2 days ( < 0.01); the water content of the brain did not change significantly at 2 h ( > 0.05) but increased significantly 2 d after the injury ( < 0.01). Treatment with the ERK inhibitor significantly lowered the permeability of blood-brain barrier and brain water content after brain trauma ( < 0.01).
CONCLUSIONS
Blocking the activation of ERK pathway significantly reduced the over-expression of MMP-9 and alleviates the damage of blood-brain barrier and traumatic brain edema, suggesting that ERK signaling pathway plays an important role in traumatic brain edema by regulating the expression of MMP-9.
