Gorham-Stout disease(GSD) is a rare osteolytic disorder characterized by spontaneous and progressive osteolysis, along with abnormal angiogenesis and lymphangiogenesis, with no new bone formation. We present a case of a 15-year-old female admitted due to " recurrent right leg pain for 5 years, 11 months after undergoing right femoral fracture surgery". Through comprehensive integration of the patient's clinical phenotype, laboratory tests, imaging findings, pathological examinations, and molecular biological test results, GSD was considered highly likely. A multidisciplinary treatment approach was conducted, including a combination of zoledronic acid and sirolimus to inhibit osteolysis, along with rehabilitation training and orthopedic intervention, providing a personalized and comprehensive treatment strategy.

Objective: To investigate the availability and use of child safety seats among children aged 0-3 years, so as to provide the basis for improving riding safety for children. Methods: Parents of children aged 0-3 years in Huangpu District, Shanghai Municipality, were recruited using the stratified multistage random sampling method from May to July 2024. Demographic information, family travel patterns, the use of child safety seat and related health beliefs were collected using questionnaire surveys. Factors affecting the use of child safety seats were identified using a multivariable logistic regression model. Results: Totally 514 valid questionnaires were recovered, with an effective rate of 96.98%. The respondents included 122 fathers (23.74%) and 392 mothers (76.26%), with a median age of 34.00 (interquartile range, 5.00) years. There were 446 families equipping with child safety seats, accounting for 86.77%; and 169 families using child safety seats, accounting for 32.88%. Multivariable logistic regression analysis showed that the parents who had children aged >1-2 years (OR=0.597, 95%CI: 0.366-0.973), travelled 2-4 times per month (OR=0.359, 95%CI: 0.213-0.607) or once per month or less (OR=0.384, 95%CI: 0.202-0.729), and scored high in perceived barrier (OR=0.634, 95%CI: 0.486-0.827) were less likely to use child safety seats; the parents who had children with local household registration (OR=2.506, 95%CI: 1.356-4.633), travelled 5-<10 km (OR=1.887, 95%CI: 1.148-3.101) or ≥10 km (OR=2.319, 95%CI: 1.355-3.967), always wore seat belts (OR=2.342, 95%CI: 1.212-4.524), scored high in perceived susceptibility (OR=1.392, 95%CI: 1.091-1.778) and self-efficacy (OR=1.413, 95%CI: 1.156-1.727) were more likely to use child safety seats. Conclusions Equipping family cars with child safety seats and using them can prevent and reduce traffic injuries among children aged 0-3 years. It is recommended to strengthen publicity to promote the use of child safety seats.

NAFLD is the most prevalent chronic liver disease,which has become a world public health issue and the incidence rate is also showing an increasing trend.A series of liver disea-ses,such as simple fatty liver disease,NASH,liver cirrhosis,liv-er failure and liver cancer,can be collectively referred to as NAFLD.Through the study of numerous factors that influence the production of NAFLD,it has been found that the main patho-logical mechanism is excessive synthesis of fat,which is difficult to be transported into the blood,causing massive lipid accumula-tion.Alcohol has a direct damaging effect on liver and will in-hibit the breakdown of liver fat,eventually forming AFLD.How-ever,it is still controversial whether alcohol has a synergistic effect on NAFLD onset.This article provides a review on the effect of alcohol intake on NAFLD and its potential mechanisms of action.

Objective:To develop an electronic information platform-based assessment tool for entrustable professional activities (EPAs) of master of nursing specialist (MNS) students.Methods:The study used the content analysis method to construct the draft of the assessment tool, which was finalized using the expert meeting method. An electronic information platform was developed based on the assessment tool. The functions of the platform was optimized using the focus group interview method.Results:Based on previous research on the EPA framework for MNS students, an EPA assessment tool was developed, including an assessment form and an assessment protocol. The assessment form consisted of three parts: description of the EPAs, supervision level, and narrative feedback. The assessment protocol covered the assessment objects, assessment initiation strategy, assessment implementation-entrustment decision making, assessment cycle, and quality control. The electronic information platform includes both web-based and mobile app interfaces, with user roles for clinical instructors, graduate students, and project administrators, and with functions such as assessment application, assessment initiation, historical assessment review, and assessment information management.Conclusions:The study developed an EPA assessment tool for MNS students. The tool relies on the convenience and efficiency of the electronic information platform, facilitates clinical instructors in observing the comprehensive performance of MNS students in multiple competencies, and promotes postgraduate students' professional development. Future research will further explore the effectiveness of this tool in assessing clinical practice competencies of MNS students, with the aim of advancing the practice of EPAs in nursing masters' education.

Objective To explore the feasibility and safety of bilateral uterine artery embolization(UAE)via distal radial artery access.Methods Thirty patients who underwent bilateral UAE were selected.They were divided into distal radial artery group(14 cases)and femoral artery group(16 cases).The clinical signs,puncture times,operation time,compression hemostasis time,discomfort scores,microcatheter non-use rates,and complication rates of the two groups were analyzed,the feasibility and safety of bilateral UAE via distal radial artery access were evaluated.Results The mean number of puncture times in the distal radial artery group was 1.6 times that of the femoral artery group,and the puncture pain score was 1.5 times that of the femoral artery group(P＜0.05).The operation time and puncture point compression hemostasis time in the distal radial artery group were shorter than those in the femoral artery group,and the discomfort score of compression hemostasis in the distal radial artery group was lower than that in the femoral artery group(P＜0.01).The proportions who did not use microcatheters in the two groups accounted for 28.6％and 6.3％,respectively,the difference was not statistically significant(P＞0.05).Four patients with poor access vessels were found in the distal radial artery group(P＜0.05).Conclusion Bilateral UAE via distal radial artery access is safe and feasible.

Aim To investigate the protective effects of methyl rosmarinate(MR)on myocardial injury in-duced by high-altitude hypoxia and explore its underly-ing mechanisms.Methods BALB/c mice were ran-domly divided into a control group,a model group,and low-,medium-,and high-dose MR groups(25,50,and 75 mg·kg-1,respectively).Except for the control group,all other groups were exposed to a hypobaric hypoxia chamber and administered MR via intraperitoneal injection daily for three days.After the experiment,myocardial tissues were collected for he-matoxylin and eosin(HE)staining to observe morpho-logical changes.Levels of malondialdehyde(MDA),glutathione(GSH),and superoxide dismutase(SOD)were measured to evaluate the anti-myocardial injury activity of MR.Network pharmacology was employed to predict drug-disease interaction targets,construct a protein-protein interaction(PPI)network,and identify core targets.Functional enrichment analysis was car-ried out using Gene Ontology(GO)and Kyoto Ency-clopedia of Genes and Genomes(KEGG)pathways.Molecular docking was used to verify the binding affini-ty of MR to core targets,and Western blot was conduc-ted to detect the expression of related proteins.Results MR significantly alleviated myocardial injury caused by high-altitude hypoxia.Network pharmacology analy-sis identified EGFR,Bcl-2,STAT3,MMP9,ESR1,and MTOR as key targets.Molecular docking con-firmed strong binding between MR and these core tar-gets.Western blot results demonstrated that MR im-proved myocardial injury by regulating the expression of STAT3,Bax,and Bcl-2 proteins.Conclusion MR may exert its protective effects on high-altitude hypoxi-a-induced myocardial injury through a multi-target mechanism.

Objective To investigate the changing prevalence and antimicrobial resistance profiles of carbapenem-resistant Enterobacterales(CRE)in Xinjiang Uygur Autonomous Region from 2017 to 2021.Methods Relevant CRE data in hospitals across Xinjiang from 2017 to 2021 were summarized according to the unified protocol of the National Antimicrobial Resistance Surveillance Network.The data were statistically analyzed by WHONET 5.6 software.Results A total of 5 071 CRE strains were identified from 165 786 strains of Enterobacterales in Xinjiang in the five-year period.The prevalence of CRE was 2.8％in 2017,3.2％in 2018,2.9％in 2019,3.1％in 2020,and 3.2％in 2021.The highest prevalence(3.3％)was in northern Xinjiang and the lowest prevalence(0)was in eastern Xinjiang.The prevalence of CRE in tertiary hospitals was higher than that in secondary hospitals.The top three species among the 5 071 CRE strains were carbapenem-resistant Klebsiella pneumoniae,carbapenem-resistant Escherichia coli,and carbapenem-resistant Enterobacter cloacae.The CRE strains were mainly isolated from the patients in ICU(34.6％),respiratory ICU(8.1％),neurosurgery(7.5％),and respiratory medicine(5.2％).The distribution of CRE species varied with patient age and gender.The carbapenem-susceptible Enterobacterales and CRE strains isolated from children were less resistant to the commonly used antibiotics in clinical practice than the corresponding strains isolated from adult patients.Conclusions The prevalent CRE strains from patients in Xinjiang are still serious.It is necessary to strengthen the surveillance of bacterial resistance and carry out multidisciplinary linkage to curb the spread and outbreak of CRE.

Aim To explore the mechanism of Jiawei Shaofu Zhuyu decoction in antagonizing endometriosis fibrosis by regulating mitophagy.Methods After the animal model was constructed,the syndrome was evalu-ated by general condition,organ water content and ther-mal imaging.The curative effect was evaluated by the weight of ectopic focus and the degree of adhesion.The pathological changes were compared using HE stai-ning,transmission electron microscopy,Masson and Sir-ius red staining.The expression of PINK1 and Parkin was detected by immunohistochemistry.The expression of mRNA and protein was determined by qPCR and Western blot,and the level of serum ROS was detected by ELISA.Results The autonomic activity of model mice was weakened,the water content of organs rose,and the temperature of limbs and lower abdomen was reduced by thermal imaging.HE staining showed obvi-ous hyperplasia of ectopic epithelium and glands.Transmission electron microscopy showed mitochondrial and endoplasmic reticulum structure damage,and nor-mal autophagy structure disappeared.Masson and Siri-us red staining showed increased collagen deposition;immunohistochemistry showed decreased expression of PINK1 and Parkin in ectopic foci.qPCR and Western blot showed that the expression of PINK1,Parkin,Bec-lin1,LC3 mRNA and protein in ectopic foci of model mice decreased,the expression of p62 mRNA and pro-tein increased,and serum ROS increased.The syn-drome performance of model mice was improved after the intervention of Jiawei Shaofu Zhuyu decoction;the inflammatory infiltration of ectopic foci was relieved,the morphology of mitochondria and endoplasmic retic-ulum was restored,and normal autophagy structure ap-peared.The degree of collagen deposition and fibrosis was reduced;the mRNA and protein expression of PINK1,Parkin,Beclin1 and LC3 increased.The ex-pression of p62 mRNA and protein decreased,and the level of ROS decreased.Conclusions Jiawei Shaofu Zhuyu decoction can improve the fibrosis of ectopic le-sions in mice with endometriosis of cold-dampness sta-sis syndrome,which may be related to the regulation of mitophagy.
