Objective To investigate the effect of oral fish oil on wound healing and related indexes in patients with diabetic foot ulcer(DFU).Methods A randomized,double-blind,placebo-controlled design was used to recruit 68 patients with DFU aged 18-80 years old in the hospital,and the baseline clinical data of the patients were collected.The patients were randomly divided into experimental group(32 cases,fish oil soft capsule,3 g/d)and control group(33 cases,corn oil soft capsule,3 g/d)by random number generated by Ex-cel,and the intervention lasted for 12 weeks.The primary endpoints included the proportion of complete wound healing and healing area≥50%.The secondary endpoints included wound area,healing time,inflamma-tion index,glucose metabolism index,nutrition related index and wound reinfection.Additionally,the influen-cing factors of wound healing were analyzed.Results After intervention,the proportion of complete wound healing and healing area≥50%in the experimental group was significantly higher than that in the control group(P=0.007,0.039).In the subjects with complete wound healing,the mean healing time in the experi-mental group was shorter than that in the control group,but the difference was not statistically significant(P=0.132).The reduction area of wound area in the experimental group was significantly larger than that in the control group(P=0.045).The decrease of interleukin(IL)-6 and IL-8 in the experimental group was significantly higher than that in the control group(P<0.05).There was no significant difference in the reduc-tion of C-reactive protein(CRP),tumor necrosis factor-α(TNF-α),neutrophil-to-lymphocyte ratio(NLR),glycated hemoglobin A1c(HbA1c)and platelet-to-lymphocyte ratio(PLR)between the two groups(P>0.05).The improvement of prealbumin(PA)in the experimental group was higher than that in the control group,but the difference was not statistically significant(P>0.05).Multivariate logistic regression analysis showed that oral fish oil intervention(OR=6.771,95%CI:1.787-25.652),HbA1c(OR=4.149,95%CI:1.026-16.770)and ulcer type(OR=4.319,95%CI:1.026-18.173)were the influencing factors of wound healing(P<0.05).Conclusion Oral fish oil promotes wound healing in patients with DFU,which may be re-lated to improving the level of chronic inflammation in the body.

Objective:To explore the structural characteristics of the medical service price network in the Yangtze River Delta,and provide a new management perspective for the collaborative governance of medical service prices in the Yangtze River Delta.Methods:Taking the related medical security bureaus of some core cities in the Yangtze River Delta as samples,based on the social network analysis method,the structural characteristics of price linkage network are analyzed from the perspectives of network density and correlation,individual centrality and block model analysis.Results:Firstly,the price network is not tight and has poor stability;secondly,the price network is unbalanced,with the Municipal Medical Insurance Bureau playing different roles;thirdly,the price network has obvious spatial aggregation and spatial spillover.Conclusion:The overall situation of the medical service price linkage network is not optimistic,and the network advantages should be fully integrated to promote the coordinated development of medical service prices in the Yangtze River Delta Region.

Based on the relevant policy documents of deepening medical service price reform in the pilot cities,combined with research and interviews,it analyzes the practical progress of measuring the total amount of medical service price adjustments in the pilot cities and the overall distribution of the total amount,the classification of items for pricing and dynamic adjustment,and the monitoring and assessment.It is suggested to explore the construction of a concise indicator system and a practical measurement method,consider the sustainability of the total price adjustment of medical services,and continue to optimize and improve the price adjustment mechanism of medical service price items.
