Objective:To summarize the experience of ambulance medical support in the 19th Hangzhou Asian Games, and provide reference for the ambulance medical support work of large-scale sports events in the future.Methods:According to the actual situation of the Asian Games, the objectives of the medical support were determined according to the principles of highlighting the key points and overall consideration. All kinds of ambulances were allocated according to the principles of combining dynamic and static and regional linkage. The ambulance support was divided into the event side and the city side,with the regional security vehicle as the supplement of the event side and the guarantee of the city side, the implementation of "one pavilion one policy", "one game one policy", "one place one policy" and "one vehicle one plan", and the interconnection of medical points (rooms), designated hospitals, management and command personnel and ambulances were realized through the Asian Games Intelligent Emergency Medical Support Syetem (EMSS).Results:Between September 16, 2023, 08:00, and October 9, 2023, 08:00, a total of 207 ambulances were deployed during the 19th Hangzhou Asian Games. Of these, 88 (42.5%) were at competition venues, 11 (5.3%) at training venues, 30 (14.5%) at non-competition venues, and 78 (37.7%) were regional support vehicles. Among them, 20 venue ambulances participated in regional support tasks during idle times. Ambulances transported patients from event sites 345 times, with the highest number of transports occurring at competition venues (187 times) and the fewest in the assisting city of Huzhou (6 times). The highest ambulance utilization rate was 70.5% at competition venues, while training venues, non-competition venues, and regional support ambulances had utilization rates of 45.5%, 53.3%, and 42.3%, respectively. The median age of transported individuals was 26 (21, 36), with a majority being male (59.1%). Athletes comprised 52.5% of transports, while staff and spectators accounted for 39.7% and 7.8%, respectively. Joint injuries were the most common condition among transported individuals, totaling 58 cases (16.8%). Regional support ambulances participated in 75 transfers and replacements, with 17 (22.7%) transfers and 58 (77.3%) replacements.Conclusions:This study confirms the feasibility and efficiency of the Asian Games' ambulance support plan, highlighting the crucial role of EMSS. The study suggests the need to strengthen medical support for staff, in addition to athletes.

Objective To investigate the serum levels of dickkopf-related protein 1 (DKK1) and sclerostin (SOST) in patients with axial spondyloarthritis treated with selective cyclo-oxygenase 2 inhibitor and its relation to clinical efficacy.Methods A randomized double-blind controlled trial with axial spondyloarthritis (ax-SpA) was carried out in our hospital.The data from patients in a single center was collected and analyzed.Serum DKK1 and SOST levels were measured by enzyme-linked immuno sorbent assay (ELISA)method before and after 12 weeks treatment,then correlation analysis were conducted for DKK1 and SOST levels with erythrocyte sedimentation rate (ESR),C reactive protein (CRP),Bath ankylosing spondylitis disease activity index (BASDAI),Bath ankylosing spondylitis functional index (BASFI) and SPARCC of the sacroiliac joint inflammation score.Chi-square tests were used for analyzing of categorical data.Fisher exact tests were performed when the expected frequencies were less than 5.Two independent samples t-test was used to compare the difference between groups.Single sample t-test was used to ompare the differences between data before and after treatment.Pearson or Spearman correlation was used for correlation analysis.Results After 12 weeks of treatment,a total of 116 patients completed the follow-up,including 57 cases of imrecoxib group and 59 cases of the celecoxib group.There were no statistically significant difference between the two groups (P>0.05).The level of serum DKK1 was significantly increased after treatment [(393±137) pg/ml,vs (542±274)pg/ml,P<0.05].The serum level of SOST increased significantly [(39±19) pg/ml vs (57±36) pg/ml,t=5.814,P>0.05],too.The difference between the two groups was not statistically significant (P>0.05).Spearman correlation analysis showed that serum DKK1 was positively correlated with serum SOST (r=0.226,P=0.015).A significantcorrelation was found between SOST level and ESR,CRP,finger to floor distance,left and fight lumbar side flexion and Schober's test (ESR:r=-0.379,P<0.01;r=-0.309,P=0.001;r=-0.225,P=0.015;r=0.185,P=0.047;r=0.247,P=0.008;r=0.214,P=0.021).Conclusion Imrecoxib and celecoxib have similar efficacy on relieving the signs and symptoms of patients with ax-SpA.Short-term application of selective COX-2 inhibitors can increase DKK1 and SOST and possibly delay radiographic progression.
