This paper mainly introduces the definition of inter-hospital transport and "hub-and-spoke" transport network in patients with extracorporeal membrane oxygenation (ECMO) , and reviews the safety management of inter-hospital transport among patients with ECMO from four aspects of transport team, transport mode, transport equipment, and transport adverse events, in order to provide reference for improving patient safety and the quality of transport care.

This paper explores the factors influencing the health-related quality of life (HRQL) of adult patients undergoing extracorporeal membrane oxygenation (ECMO) from five dimensions based on the health ecology model: personal characteristics, behavioral traits, interpersonal networks, work and living environment, and policy environment. The aim is to provide a theoretical basis for proposing evidence-based interventions to effectively improve the HRQL of adult ECMO patients.

Objective:To investigate the protective effects and mechanisms of targeted inhibition of type 3 deiodinase (Dio3) on skeletal muscle mitochondria in sepsis.Methods:① In vivo experiments: adeno-associated virus (AAV) was employed to specifically target Dio3 expression in the anterior tibial muscle of rats, and a septic rat model was generated using cecal ligation and puncture (CLP). The male Sprague-Dawley (SD) rats were divided into shNC+Sham group, shD3+Sham group, shNC+CLP group, and shD3+CLP group by random number table method, with 8 rats in each group. After CLP modeling, tibial samples were collected and Western blotting analysis was conducted to assess the protein levels of Dio3, peroxisome proliferator-activated receptor-γ coactivator-1α (PGC1α), and silence-regulatory protein 1 (SIRT1). Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was utilized to examine mRNA expression of genes including thyroid hormone receptors (THRα, THRβ), monocarboxylate transporter 10 (MCT10), mitochondrial DNA (mtDNA), and PGC1α. Transmission electron microscopy was employed to investigate mitochondrial morphology. ② In vitro experiments: involved culturing C2C12 myoblasts, interfering with Dio3 expression using lentivirus, and constructing an endotoxin cell model by treating cells with lipopolysaccharide (LPS). C2C12 cells were divided into shNC group, shD3 group, shNC+LPS group, and shD3+LPS group. Immunofluorescence colocalization analysis was performed to determine the intracellular distribution of PGC1α. Co-immunoprecipitation assay coupled with Western blotting was carried out to evaluate the acetylation level of PGC1α. Results:① In vivo experiments: compared with the shNC+Sham group, the expression of Dio3 protein in skeletal muscle of the shNC+CLP group was significantly increased (Dio3/β-Tubulin: 3.32±0.70 vs. 1.00±0.49, P < 0.05), however, there was no significant difference in the shD3+Sham group. Dio3 expression in the shD3+CLP group was markedly reduced relative to the shNC+CLP group (Dio3/β-Tubulin: 1.42±0.54 vs. 3.32±0.70, P < 0.05). Compared with the shNC+CLP group, the expression of T3-regulated genes in the shD3+CLP group were restored [THRα mRNA (2 -ΔΔCt): 0.67±0.05 vs. 0.33±0.01, THRβ mRNA (2 -ΔΔCt): 0.94±0.05 vs. 0.67±0.02, MCT10 mRNA (2 -ΔΔCt): 0.65±0.03 vs. 0.57±0.02, all P < 0.05]. Morphology analysis by electron microscopy suggested prominent mitochondrial damage in the skeletal muscle of the shNC+CLP group, while the shD3+CLP group exhibited a marked improvement. Compared with the shNC+Sham group, the shNC+CLP group significantly reduced the number of mitochondria (cells/HP: 10.375±1.375 vs. 13.750±2.063, P < 0.05), while the shD3+CLP group significantly increased the number of mitochondria compared to the shNC+CLP group (cells/HP: 11.250±2.063 vs. 10.375±1.375, P < 0.05). The expression of mtDNA in shNC+CLP group was markedly reduced compared with shNC+Sham group (copies: 0.842±0.035 vs. 1.002±0.064, P < 0.05). Although no difference was detected in the mtDNA expression between shD3+CLP group and shNC+CLP group, but significant increase was found when compared with the shD3+Sham group (copies: 0.758±0.035 vs. 0.474±0.050, P < 0.05). In the shD3+CLP group, PGC1α expression was significantly improved at both transcriptional and protein levels relative to the shNC+CLP group [PGC1α mRNA (2 -ΔΔCt): 1.49±0.13 vs. 0.68±0.06, PGC1α/β-Tubulin: 0.76±0.02 vs. 0.62±0.04, both P < 0.05]. ② In vitro experiments: post-24-hour LPS treatment of C2C12 cells, the cellular localization of PGC1α became diffuse; interference with Dio3 expression promoted PGC1α translocation to the perinuclear region and nucleus. Moreover, the acetylated PGC1α level in the shD3+LPS group was significantly lower than that in the shNC+LPS group (acetylated PGC1α/β-Tubulin: 0.59±0.01 vs. 1.24±0.01, P < 0.05), while the expression of the deacetylating agent SIRT1 was substantially elevated following Dio3 inhibition (SIRT1/β-Tubulin: 1.04±0.04 vs. 0.58±0.03, P < 0.05). When SIRT1 activity was inhibited by using EX527, PGC1α protein expression was notably decreased compared to the shD3+LPS group (PGC1α/β-Tubulin: 0.92±0.03 vs. 1.58±0.03, P < 0.05). Conclusion:Inhibition of Dio3 in skeletal muscle reduced the acetylation of PGC1α through activating SIRT1, facilitating nuclear translocation of PGC1α, thereby offering protection against sepsis-induced skeletal muscle mitochondrial damage.

Objective This study aims to develop a prognostic risk prediction model for gastric cancer based on m1A/m5C/m6A/m7G regulated genes and to investigate the relationship between this model and immunology.Methods The Cancer Genome Atlas(TCGA)gastric cancer dataset was utilized to identify m1A/m5C/m6A/m7G regulated genes with significant expression differences.A prognostic risk score(RS)model was constructed using univariate Cox regression analysis and the LASSO algorithm.The RS model was validated using the Kaplan-Meier(K-M)statistic and cell lines for RT-qPCR biological validation.A nomogram model was created using univariate and multivariate Cox regression analyses.The CIBERSORT algorithm and ESTIMATE package were employed to conduct immune correlation analysis.Results A prognostic RS model based on eight methylation regulated genes was developed to classify patients with gastric cancer as high-risk or low-risk.These eight genes showed significant expression in gastric cancer cell lines(P＜0.05).The TCGA-gastric cancer training set and GSE62254-validation set showed a substantial connection(P＜0.001)between overall survival rate(OS)and grouping status.The nomogram survival models accurately predicted 1-year(C-index = 0.703),3-year(C-index = 0.729),and 5-year(C-index = 0.734)survival rates.Immune correlation analysis showed that compared to the low-risk group,the high-risk group had higher immune scores and higher expression of immune checkpoint-related genes(P＜0.05).Conclusion We created a reliable prognostic RS model based on m1A/m5C/m6A/m7G regulated genes that can predict gastric cancer prognosis and guide individualized immunotherapy decisions.

Background and purpose:Gastric-type endocervical adenocarcinoma(G-EAC)is a rare variant of endocervical adenocarcinoma,characterized by atypical clinical manifestations and elusive lesions.Due to these factors,G-EAC is prone to being missed or misdiagnosed,significantly impacting the prognosis.Lobular endocervical glandular hyperplasia(LEGH)and atypical LEGH(aLEGH)are considered to be precancerous lesions of G-EAC.These conditions also present overlapping clinical,pathologic and imaging manifestations,making it challenging to differentiate between them preoperatively.The purpose of this study was to investigate the correlation between magnetic resonance imaging(MRI)findings of cystic-solid lesions in the cervix and their underlying pathology in order to enhance the accuracy of distinguishing between LEGH and G-EAC,ultimately aiding in the early diagnosis and appropriate management of these conditions.Methods:Clinical,imaging and pathological data of 37 LEGH and 53 G-EAC patients who attended the Obstetrics and Gynecology Hospital of Fudan University from July 2016 to August 2023 were collected.Analysis was conducted using Pearson Chi-square χ2,Fisher's exact tests and so on.Multivariate analyses were performed using logistic regression.Receiver operating characteristic(ROC)curves were used for performance evaluation.Results:In this study,differences in age,symptoms,extent,size,composition,degree of enhancement,cervical stromal ring,endometrium invasion,pelvic lymph nodes enlargement,and hydrohystera were statistically significant between the two groups(P＜0.05).In the LEGH and aLEGH groups,lesions were primarily localized to the epithelial layer of the endocervical canal.These lesions were predominantly simple cystic(32/37),and the cystic walls often displayed significant enhancement(31/37).In contrast,the G-EAC group presented with lesions involving the myometrium of the uterine cervix(42/53).These lesions were characterized by a solid component in the majority of cases(52/53),a tendency for the disappearance of the cervical stromal ring(46/53).Logistic regression analysis revealed that among the MRI features,lesion composition(OR=50.064)and incomplete cervical stromal ring(OR=40.180)were significant predictors for G-EAC.ROC analysis,incorporating lesion size,composition,enhancement degree,cervical stromal ring,and endometrial involvement,yielded an area under curve(AUC)of 0.970(95%CI:0.931-1.008).Conclusion:Combining multiple MRI features of cystic-solid lesions in the cervix aids in distinguishing between LEGH and G-EAC.

Objective:To study the relationship between fluoride exposure and adrenocorticotropic hormone (ACTH)/cortisol (CORT) in rural children in eastern Henan, and to reveal the modifying effect of brain-derived neurotrophic factor (BDNF) gene polymorphism.Methods:A total of 463 children aged 7 - 12 (245 boys and 218 girls) from 4 primary schools in Tongxu County, Henan Province were recruited by a cluster sampling method for questionnaire survey, physical examination, and collection of morning urine and fasting venous blood. The concentrations of urinary fluoride and creatinine were determined by a fluoride ion selective electrode method and picric acid method, respectively. Serum ACTH and CORT levels were determined with a fully automated biochemical analyzer, and the genotyping of BDNF gene loci of single nucleotide polymorphism was conducted by a customized 48-Plex SNPscan TM reagent kit. Besides, the relationships between urinary fluoride concentrations and serum ACTH/CORT levels in children were analyzed by multiple linear regression models. The interaction term between urinary fluoride concentration and BDNF gene polymorphism was established, and the interaction between unit point gene polymorphism and environment on serum ACTH or CORT levels of children was analyzed by multiple linear regression. Results:For every 1 mg/L increase in urinary fluoride concentration, serum ACTH level in girls increased by 1.98 pg/ml [95% confidence interval ( CI): 0.71, 3.24; P = 0.002], while serum CORT level in boys decreased by 37.48 ng/ml (95% CI: - 63.99, - 10.97; P = 0.006). Regardless of stratified analysis, the urinary fluoride concentration of individuals carrying the TA genotype at the rs6484320 locus was positively correlated with serum ACTH level (β > 0, P < 0.05); in addition, there was a positive correlation between urinary fluoride concentration and serum ACTH level in the total population and boys carrying the CC genotype of rs7103873 locus (β > 0, P < 0.05); and the serum ACTH and CORT levels in girls carrying the AA genotype of rs12291186 locus were positively correlated with urinary fluoride concentration (β > 0, P < 0.05). The interaction analysis showed that there was an interaction between urinary fluoride concentrations and rs6484320/rs7103873 loci polymorphisms on serum ACTH level in the total population and boys ( Pinteraction < 0.1), as well as urinary fluoride concentrations and rs12291186 locus polymorphism on serum CORT level in girls ( Pinteraction = 0.035). Conclusions:Urinary fluoride concentration is associated with increased serum ACTH level in girls and decreased serum CORT level in boys. BDNF gene polymorphism can modify the association between fluoride exposure and serum ACTH or CORT levels in children, and the modification effect varies by gender.

Objective:To investigate the effect of lower limb exoskeleton robots on balance function in children with spas-tic diplegia. Method:Twenty children with spastic diplegia who were admitted to the Department of Rehabilitation of the Children's Hospital of Zhejiang University School of Medicine from July 2022 to December 2022 were includ-ed in the treatment group.The other 20 children matched with age,gender and functional status were includ-ed in the control group.Both groups were given conventional rehabilitation training(exercise therapy,suspen-sion training,isokinetic muscle strength training),and the treatment group were received the 30-min lower limb exoskeleton robot training 5 times a week for 8 weeks.Before and after treatment,the two groups were tested with surface electromyography(sEMG)data,dynamic balance response displacement,static balance score,and Pediatric Balance Scale(PBS). Result:Before treatment,there was no statistically significant difference(P＞0.05)in sEMG values(gluteus maximus,gluteus medius,quadriceps femoris and tibialis anterior muscle),dynamic balance reaction displace-ment,static balance score,and PBS score between the two groups.There were significant improvements in the scores of these measurements(P＜0.05)in both group before and after treatment.Compared with the con-trol group,there were statistically significant differences in sEMG values(gluteus maximus P=0.021;gluteus medius P=0.016;quadriceps femoris P=0.004),dynamic balance reaction displacement(anterior P=0.014;left P=0.003;right P=0.003),static balance score(P=0.005),and PBS score(P=0.004)in the treatment group af-ter treatment. Conclusion:Lower limb exoskeleton robot gait training combined with conventional rehabilitation treatment can effectively improve the balance function of cerebral palsy children with spastic diplegia.

Objective To investigate the changes in distribution of Oncomelania hupensis snails in forestlands in Songjiang District, Shanghai Municipality from 2009 to 2023, so as to provide insights into formulation of O. hupensis snail surveillance programs. Methods The reports on O. hupensis snail surveillance in Songjiang District, Shanghai Municipality from 2009 to 2023 were collected, and the snail surveillance data in forestlands were extracted. The trends in the proportion of areas with snails in forestlands in total areas with snails, occurrence of frames with living snails and density of living snails were evaluated using a Joinpoint regression model in Songjiang District from 2009 to 2023, and the annual percent change (APC) and average annual percent change (AAPC). Results A total of 40 sites with snails were found in forestlands in 14 administrative villages of 4 townships, Songjiang District, Shanghai Municipality from 2009 to 2023. A total of 39 065 frames were surveyed for snails in settings covering an area of 609 600 m², and there were 6 084 frames with snails, covering 151 250 m² snail habitats. A total of 22 210 snails were captured, with the highest density of 260.00 snails/0.1 m², and 6 262 snails were dissected, with no Schistosoma japonicum infection identified in snails. The proportion of areas with snails in forestlands in total areas with snails appeared a tendency towards a rise in forestlands in Songjiang District, Shanghai Municipality from 2009 to 2023 (APC = AAPC = 24.9%, P > 0.05); however, there were no turning points in the trend curve, with the highest proportion seen in 2009 (53.81%), the lowest in 2011 and 2023 (both 0) and a mean proportion of 24.81%. The occurrence of frames with living snails appeared a tendency towards a rise from 2009 to 2023 (APC = AAPC = 41.5%, P > 0.05); however, there were no turning points in the trend curve, with the highest occurrence in 2009 (53.81%), the lowest in 2011 and 2013 (both 0), and the mean occurrence of 15.57%. In addition, the density of living snails appeared a tendency towards a rise from 2009 to 2023 (APC = AAPC = 55.0%, P > 0.05); however, there were no turning points in the trend curve, with the highest density in 2023 (0.96 snails/0.1 m²), the lowest in 2011 and 2013 (both 0), and a mean density of 0.57 snails/0.1 m². Conclusions The difficulty in O. hupensis snail control and risk of imported snails appeared a tendency towards a rise in forestlands in Songjiang District, Shanghai Municipality over years from 2009 to 2023. Supervision and assessment prior to seedling transplantation and intensified surveillance post-transplantation are recommended to reduce the risk of O. hupensis snail importation and spread.

ObjectiveTo analyze the monitoring results and trends of Oncomelania in Songjiang District of Shanghai from 2007 to 2023， and to provide reference for future monitoring work. MethodsThe data of snail monitoring in Songjiang District from 2007 to 2023 were collected， including the location of snail spots， the number of survey frames， the area with snails， the number of frames with snails， the total number of snails， etc. The density of living snails and the occurrence rate of living snail frames were calculated. ResultsFrom 2007 to 2023， a total of 158 snail spots were found in 22 administrative villages in 4 towns in Songjiang District， including 131 emerging snail habitats （82.91%） and 27 reemerging snail habitats （17.09%）. The total snail area was 175 980 m²， the number of snail frames was 10 061， and 33 302 snails were captured. The highest density was 260/0.11 m²， and 15 662 snails were dissected. No positive snails were found. The average density of living snails was 0.60/0.11 m² and the average occurrence rate of living snail frames was 17.99%. The snail areas in different areas were Yexie Town 126 000 m² （71.60%）， Maogang Town 26 470 m² （15.04%）， Xinbang Town 17 040 m² （9.68%）， and Shihudang Town 6 470 m² （3.68%）. The average density of living snails in different areas was 0.89/0.11 m² in Yexie Town， 0.65/0.11 m² in Maogang Town， 0.26/0.11 m² in Shihudang Town and 0.24/0.11 m² in Xinbang Town. The snail areas of different snail habitats were as follows： woodland 151 250 m²（85.95%）， river 13 810 m²（7.85%）， ditch 6 910 m²（3.93%）， farmland 4 010 m²（2.28%）. The average density of living snails in different snail habitats： ditch 1.01/0.11 m²， beach 0.86/0.11 m²， woodland 0.57/0.11 m²， river 0.40/0.11 m². The occurrence rate of living snail frames in different regions and different snail environment types showed a downward trend and the difference was statistically significant. ConclusionAlthough the snail monitoring indicators such as snail area， average living snail density and average living snail frame occurrence rate in Songjiang District are still at its historically low level， the average living snail density and average living snail frame occurrence rate are still high compared with other regions or the national average. We should focus on the upper reaches and tributaries of the Huangpu River， especially the key areas of seedling transplantation， and strengthen monitoring and supervision to reduce the risk of snail input.

Objective:To investigate personal exposures to nitrogen oxides(NOX)and nitrogen di-oxide(NO2)and the influence of baseline personal characteristics,living environment and daily activity patterns of the participants on the exposures among adults over 35 in Tianjin and Shanghai.Methods:In this panel study,91 healthy nonsmoking adults aged over 35 from Tianjin and Shanghai participated in our study.The study was conducted in summer and winter.The participants were followed for three times with an interval of at least two weeks.Only participants in Shanghai were followed once in winter because of the COVID-19 pandemic.Twenty-seven participants completed follow-up visits in both seasons.We measured their 24 h personal exposures to NOX and NO2and collected their baseline and time-activity in-formation through questionnaire/diary.The linear mixed model was used to analyze the associations be-tween potential influencing factors and personal NOX and NO2 exposure levels.Results:There were 349 follow-up visits with valid 24 h personal NO2 and NOX exposure measurements in the two cities.The ave-rage 24 h personal exposures to NO2 and NOX(volume fraction)in Tianjin participants were 18.0 x 10-9 and 26.2 × 10-9 in summer,and 31.0 x 10-9 and 54.9 x 10-9in winter,respectively;and the average 24 h personal exposures to NO2 and NOX in Shanghai participants were 38.7 x 10-9and 100.0x10-9in summer,and 45.5 x10-9 and 139.2 x 10-9 in winter,respectively.The results of univariate regression analysis showed that their personal NOX exposure levels were significantly associated with city,season,gender,average daily cooking times,and ambient NO2 concentrations measured at fixed-site monitoring stations.In addition to the above factors,the personal NOX exposure levels were also significantly associ-ated with educational level and the personal NO2 exposure levels were also significantly associated with passive smoking,average daily home time,cooking energy type,residential distance from main traffic road,and use of kitchen ventilators.Multivariate regression analysis showed that the personal exposure levels of NO2 and NOX were significantly lower in Tianjin than that in Shanghai,were significantly lower in summer than that in winter,and were significantly and positively associated with ambient NO2 concen-trations measured at fixed-site monitoring stations.In addition,personal NOX exposure levels were signifi-cantly lower in females than in males,and personal NO2 exposure levels were significantly positively asso-ciated with average daily cooking times and significantly inversely associated with average daily home time.For every interquartile range(IQR)increase(12.7 × 10-9)in ambient NO2,the personal NO2 exposure levels increased by 27.5％(95％CI:17.0％-38.9％),and personal NOX exposure levels in-creased by 16.1％(95％CI:7.1％-25.8％).Conclusion:Season,city and ambient NO2 concentra-tions are significant influencing factors of personal exposure levels of NO2and NOX At the same time,the personal exposures levels of NO2 are also affected by lifestyle factors.Our study provides scientific evi-dence for making precise air pollution control decisions and reducing the exposure levels of NOX in the population.
