Objective:To construct a risk prediction model based on explainable intelligence(XAI)analysis algorithms for orthopedic consumables in surgery room,and improve the management quality of controlling risk for orthopedic consumables in surgery room.Methods:A risk index system for orthopedic consumables in the surgery room was established through researching literature and using Delphi method.The data of supply and use of consumables were collected to construct a risk prediction model.Risk control paths were formulated from three aspects included formulating preoperative plan,intraoperative dynamic allocation,and postoperative tracking and feedback.A total of 6,572 sets of orthopedic consumables that were used in the surgery room of the 960th Hospital of People's Liberation Army Joint Service Support Force from January 2021 to December 2024 were selected.The 3,185 sets of orthopedic consumables that were used during January 2021 and December 2022 were managed by using conventional method of controlling and managing risk.The 3,387 sets of orthopedic consumables that were used during January 2023 and December 2024 were managed by using intelligent method of controlling and managing risk.The early warning capabilities for risk,and the control quality for risk between the two management methods were compared.A self-made satisfaction survey questionnaire was adopted to investigate the satisfaction scores of medical staffs and managers for consumables in the surgery room for the two management methods.Results:The average accuracy rates of using the intelligent method of controlling and managing risk in predicting formulating preoperative plan,intraoperatively dynamic allocation,and postoperative tracking and feedback for early warning events of risk in 157,247 and 57 consumables were respectively 49.68%(78/157),42.11%(104/247)and 56.14%(32/57),all of which were higher than those of conventional method of controlling and managing risk,and the difference were statistically significant(x2=9.475,23.637,13.035,P<0.05).The average reduction rate of risk events of consumables,the average intervention rate of abnormal use of consumables,and the mean value of enhance degree of turnover efficiency of consumables were respectively(6.25±1.59)%,(87.93±4.44)%and(4.78±1.69)%,all of which were higher than those of conventional method of controlling and managing risk,and the differences were statistically significant(t=4.952,6.257,4.660,P<0.05).The scores of medical staffs and managers in surgery room for acceptance of early warning for risk,support of management decision,satisfaction of using consumables,and assessment results of training by adopting intelligent method of controlling and managing risk were all higher than those by adopting conventional method of controlling and managing risk,and the differences were statistically significant(t=3.368,3.082,3.701,4.558,P<0.05).Conclusion:The application of prediction model based on XAI analysis algorithm for risk of orthopedic consumables in the surgery room can improve the accuracy of early warning for risk of orthopedic consumables in the surgery room,and reduce the incidence of risk events,and enhance the ability of emergent response for risk,and improve the quality of clinical services.

Objective To explore the value of Turbo-Flash mode CT scanning for displaying calcification of ligamentum arteriousum(CLA)in infants and young children.Methods Chest CT data obtained with Turbo-Flash mode scanning of 1 762 infants and young children(aged 1 to 36 months)with suspected lung,trachea or bronchi lesions were retrospectively analyzed.Children were divided into group A to L according to age at 3-month intervals.CLA was evaluated and its CT manifestations were analyzed.The incidence of CLA in each group was counted,the density of CLA was measured,and their correlations with age were observed.Results Among 1 762 children,912 was found with CLA(912/1 762,51.76%).The incidence of CLA in group A—L was 34.29%(12/35)—59.35%(92/155),respectively.All CLA located in the arterial ligaments between the left side of pulmonary trunk and the origin level of left subclavian artery of the aorta and shaped differently.The density of CLA in group A—L was(183.36±50.16)—(295.80±105.91)HU,respectively.The incidence of CLA in group A—F was positively(r=0.945,P=0.002),while in group F—L was negatively correlated with age(r=-0.765,P=0.045).Meanwhile,the density of CLA in group A—F was positively correlated with age(r=0.775,P=0.020),but no significant correlation between CLA density and age was found in G—L group(P=0.593).Conclusion Turbo-Flash mode CT scanning had high clinical application value for displaying CLA in infants and young children.

In order to explore the effects of lipopolysaccharide(LPS)on the repair of bovine endo-metrial stromal cells(BESCs)during inflammatory response,BESCs were treated by LPS in this study.Cell apoptosis rate was detected using flow cytometry,cell viability was measured using the CCK-8 assay,cell migration ability was observed using a scratch assay,and the expression of con-nective tissue growth factor(CTGF),transforming growth factor-beta 3(TGF-β3)and vascular endothelial growth factor(VEGF)mRNA was measured using qRT-PCR.Additionally,the expression of key proteins in the PI3K/AKT and Wnt/β-catenin signaling pathways was assessed using Western blot analysis.The results showed that cell viability of BESCs significantly decreased(P＜0.01),cell migration ability decreased(P＜0.05),apoptosis rate of BESCs increased(P＜0.01),CTGF and TGF-β3 mRNA expression levels decreased(P＜0.01),while VEGF mRNA ex-pression increased after treatment with LPS(P＜0.01).The phosphorylation levels of PI3K,AKT and GSK-3β proteins decreased(P＜0.05),as well as the expression levels of c-Myc and Cyclin-D1 proteins also decreased(P＜0.01).These results indicated that LPS can inhibit the proliferation of BESCs and promote cell apoptosis possibly through the inhibition of the PI3K/AKT and Wnt/β-catenin signaling pathways.
