ABSTRACT
Objective:To understand the capability of the emergency service at township hospitals in Fushun county and take emergency treatment of pesticide poisoning in Fushun as an example to measure the spatial accessibil-ity of the emergency service center. Methods:Gathered the heads of 26 township hospitals,using self compiled ques-tionnaire to collect emergency services data;basic data including administrative districts,hydrographic net,road net-work, population distribution and the position of the first aid post were collected, Travel cost method was used to quantitatively measure the emergency service spatial accessibility based on GIS platform. Results: The proportion of hospitals that are able to carry out rescue projects is low;it takes 13.57minutes on average from a residential area to a first aid post of pesticide poisoning in Fushun. The regions with poor accessibility of the first aid post are mainly distributed in the southwest boundary. Conclusion:The hardware and software level of emergency resources of town-ship hospitals in Fushun were lower;Township emergency network need to be improved;That using GIS to assess the accessibility of the first aid post is intuitive and easy to operate.
ABSTRACT
Twenty-eight compounds were isolated and purified from Clinopodium chinense by Sephedax LH-20, ODS, MCI and preparative HPLC. Their structures were identified as apigenin (1), apigenin-7-O-β-D-glucopyranoside (2), apigenin-7-O-β-D-glucuronopyranoside (3), thellungianol (4), apigenin-7-O-β-D-rutinoside (5), luteolin (6), luteolin-4'-O-β-D-glucopyranoside (7), apigenin-7-O-β-D-pyranglycuronate butyl ester (8), luteolin-7-O-β-D-rutinoside (9), luteolin-7-O-β-D-noehesperidoside (10), acacetin (11), acacetin-7-O-β-D-glucuronopyranoside (12), buddleoside (13), naringenin (14), pruning (15), nairutin (16), isosakuranetin (17), isosakuranin (18), didymin (19), hesperidin (20), kaempferol (21), quercetin (22), kaempferol-3-O-α-L-rahmnoside (23), p-hydroxycinnamic acid (24), caffeic acid (25), cis-3-[2-[1-(3,4-dihydroxy-phenyl)-1 -hydroxymethyl]-1,3-ben-zodioxol-5-yl]-(E)-2-propenoic acid (26), mesaconic acid (27), gentisic acid 5-O-β-D-(6'-salicylyl)-glucopyranoside (28). Among them, compounds 7, 9-10, 12, 23, 26-28 were isolated from the Clinopodium for the first time. The protective effects of compounds 1-6, 8-17 and 19 against H2O2-induced H9c2 cardiomyocyte injury were tested, compounds 15 exhibited significantly protective effects. Compared with the cell viability of (62.12±6.18)% in the model, pruning exhibited viabilities of (84.25±7.36)% at 25.0 mg•L⁻¹, respectively, using quercetin as a positive control [cell viability of (84.55±8.26)%, 20 mg•L⁻¹].
