RESUMEN
BACKGROUND AND PURPOSE: To assess the relationship between metastatic lymph node (LN) responder status and recurrence-free survival (RFS) in patients undergoing neoadjuvant chemoradiotherapy (NCRT). MATERIALS AND METHODS: We retrospectively reviewed 304 patients with local advanced esophageal squamous cell carcinoma received NCRT followed by esophagectomy. For 112 patients with positive node, according to the proportion of residual viable tumor cells area within the whole tumor beds of all metastatic LNs, we classified LN-tumor regression grade (LN-TRG) into four categories: grade 1, 0%; 2, <10%; 3, 10%-50%; 4, >50%. Patients with grade 1-2 LN-TRG of were considered LN responders, and those with grades 3-4, as LN nonresponders. Univariate and multivariate analyses of RFS were estimated by a Cox regression model, Kaplan-Meier curve, and log-rank test. RESULTS: The median follow-up time of a total of 112 patients was 29.6 months. Fifty-two (46.4%) patients have experienced recurrence. In Cox univariate analysis, differentiation, AJCC stage LN responder status, nerve invasion, and lymphovascular invasion significantly correlated with RFS. Multivariate analysis for RFS revealed that LN responder status and AJCC stage (p < 0.05) were independent prognostic factor. The 3-year RFS rates for patients with LN-TRG of 1-4 grades were 72.7%, 76.5%, 37.4%, and 28.5%, respectively, and the median RFS times were not reach, 43.56, 28.09, and 22.77, respectively. CONCLUSIONS: LN responder status is an independent prognostic factor for RFS in esophageal cancer patients who received NCRT.

BACKGROUND: Assessment of the effective use of international travel measures during the COVID-19 pandemic has focused on public health goals, namely limiting virus introduction and onward transmission. However, risk-based approaches includes the weighing of public health goals against potential social, economic and other secondary impacts. Advancing risk-based approaches thus requires fuller understanding of available evidence on such impacts. METHODS: We conducted a scoping review of existing studies of the social impacts of international travel measures during the COVID-19 pandemic. Applying a standardized typology of travel measures, and five categories of social impact, we searched 9 databases across multiple disciplines spanning public health and the social sciences. We identified 26 studies for inclusion and reviewed their scope, methods, type of travel measure, and social impacts analysed. RESULTS: The studies cover a diverse range of national settings with a strong focus on high-income countries. A broad range of populations are studied, hindered in their outbound or inbound travel. Most studies focus on 2020 when travel restrictions were widely introduced, but limited attention is given to the broader effects of their prolonged use. Studies primarily used qualitative or mixed methods, with adaptations to comply with public health measures. Most studies focused on travel restrictions, as one type of travel measure, often combined with domestic public health measures, making it difficult to determine their specific social impacts. All five categories of social impacts were observed although there was a strong emphasis on negative social impacts including family separation, decreased work opportunities, reduced quality of life, and inability to meet cultural needs. A small number of countries identified positive social impacts such as restored work-life balance and an increase in perceptions of safety and security. CONCLUSIONS: While international travel measures were among the most controversial interventions applied during the COVID-19 pandemic, given their prolonged use and widespread impacts on individuals and populations, there remains limited study of their secondary impacts. If risk-based approaches are to be advanced, involving informed choices between public health and other policy goals, there is a need to better understand such impacts, including their differential impacts across diverse populations and settings.

AIM: To explore the impact of the Omicron variant on maternal and neonatal outcomes. DESIGN: Cross-sectional cohort study of women giving live birth in a single hospital in Shanghai in December 2022. METHODS: Demographic characteristics, maternal and neonatal outcomes and laboratory testing results were retrieved from medical records. Propensity score matching was used to match COVID-19-positive and -negative women. Differential analysis was used to assess associations between COVID-19 and in-hospital maternal and neonatal outcomes. RESULTS: A total of 1508 women were included, comprising 729 natural births, 741 caesarean sections and 38 forceps deliveries. After 1:1 matching, 310 clients were included for analysis with each 155 in COVID-19-positive and -negative groups. Higher maternal fever was found in all modes of delivery, and higher preterm birth and lower pH value of blood gas of the umbilical artery in the vaginal delivery subgroup (p < 0.05). Other maternal and neonatal outcomes showed no significant difference between COVID-19-positive and -negative clients.

INTRODUCTION: Assessment of the use of travel measures during COVID-19 has focused on their effectiveness in achieving public health objectives. However, the prolonged use of highly varied and frequently changing measures by governments, and their unintended consequences caused, has been controversial. This has led to a call for coordinated decision-making focused on risk-based approaches, which requires better understanding of the broader impacts of international travel measures (ITMs) on individuals and societies. METHODS: Our scoping review investigates the literature on the economic impact of COVID-19 ITMs. We searched health, social science and COVID-19-specific databases for empirical studies preprinted or published between 1 January 2020 and 31 October 2023. Evidence was charted using a narrative approach and included jurisdiction of study, ITMs studied, study design, outcome categories, and main findings. RESULTS: Twenty-six studies met the inclusion criteria and were included for data extraction. Twelve of them focused on the international travel restrictions implemented in early 2020. Limited attention was given to measures such as entry/exit screening and vaccination requirements. Eight studies focused on high-income countries, 6 on low-income and middle-income countries and 10 studies were comparative although did not select countries by income. Economic outcomes assessed included financial markets (n=13), economic growth (n=4), economic activities (n=1), performance of industries central to international travel (n=9), household-level economic status (n=3) and consumer behaviour (n=1). Empirical methods employed included linear regression (n=17), mathematical modelling (n=3) and mixed strategies (n=6). CONCLUSION: Existing studies have begun to provide evidence of the wide-ranging economic impacts resulting from ITMs. However, the small body of research combined with difficulties in isolating the effects of such measures and limitations in available data mean that it is challenging to draw general and robust conclusions. Future research using rigorous empirical methods and high-quality data is needed on this topic.

Angiotensin II (Ang II) is associated with macrophage polarization and apoptosis, but the role of the angiotensin type 2 receptor (AT2R) in these processes remains controversial. However, the effect of AT2Rs on alveolar macrophages and mechanical ventilation-induced lung injury has not been determined. Mechanical ventilation-induced lung injury in SpragueâDawley (SD) rats and LPS-stimulated rat alveolar macrophages (NR8383) were used to determine the effects of AT2Rs, selective AT2R agonists and selective AT1Rs or AT2R antagonists. Macrophage polarization, apoptosis, and related signaling pathways were assessed via western blotting, QPCR and flow cytometry. AT2R expression was decreased in LPS-stimulated rat alveolar macrophages (NR8383). Administration of the AT2R agonist CGP-42112 was associated with an increase in AT2R expression and M2 polarization, but no effect was observed upon administration of the AT2R antagonist PD123319 or the AT1R antagonist valsartan. In mechanical ventilation-induced lung injury in SpragueâDawley (SD) rats, the administration of the AT2R agonist C21 was associated with attenuation of the pathological damage score, lung wet/dry weight, cell count and protein content in BALF. C21 can significantly reduce proinflammatory factor TNF-α, IL-1ß levels, increase anti-inflammatory factor IL-4, IL-10 levels in BALF, compared with the model group (p < 0.01). Similarly, compared with those at the same time points, the M1/M2 ratios in alveolar macrophages and apoptosis in peritoneal macrophages at 4 h, 6 h and 8 h in the mechanical ventilation models were lower after C21 administration. These findings indicated that the expression of AT2Rs in alveolar macrophages mediates M1 macrophage polarization and apoptosis and that AT2Rs play a protective role in mediating mechanical ventilation-induced lung injury.
RESUMEN
Echovirus 11 (E11) has gained attention owing to its association with severe neonatal infections. From 2018 to 2023, a surge in severe neonatal cases and fatalities linked to a novel variant of genotype D5 was documented in China, France, and Italy. However, the prevention and control of E11 variants have been hampered by limited background data on the virus circulation and genetic variance. Therefore, the present study investigated the circulating dynamics of E11 and the genetic variation and molecular evolution of genotype D5 through the collection of strains from the national acute flaccid paralysis (AFP) and hand, foot, and mouth disease (HFMD) surveillance system in China during 2000-2022 and genetic sequences published in the GenBank database. The results of this study revealed a prevalent dynamic of E11 circulation, with D5 being the predominant genotype worldwide. Further phylogenetic analysis of genotype D5 indicated that it could be subdivided into three important geographic clusters (D5-CHN1: 2014-2019, D5-CHN2: 2016-2022, and D5-EUR: 2022-2023). Additionally, variant-specific (144) amino acid mutation sites and positive-selection pressure sites (132, 262) were identified in the VP1 region. Cluster-specific recombination patterns were also identified, with CVB5, E6, and CVB4 as the major recombinant viruses. These findings provide a preliminary landscape of E11 circulation worldwide and basic scientific data for further study of the pathogenicity of E11 variants.

Syndrome is an important concept in the theoretical system of tradtional Chinese medicine (TCM), and the four-dimensional attributes of syndrome are proposed based on clinical practice, namely materiality, regularity, complexity and holism. The materiality of syndrome is an objective existence that can be perceived and seen, and it can be perceived from more levels by using modern science and technology to explore the visualisation, objectification and digitisation of syndrome; the regularity of syndrome is hierarchical, can be grasped, for example in the beginning of the epidemic the pathogen is unknown, and grasping the regularity of syndrome can make a rapid response in the treatment of the epidemic; the complexity of syndrome is not only reflected in the geographical, seasonal and individual differences, but also reflected in the development of the dynamics of a certain period of law, especially for the epidemic disease with characteristics of rapid onset, rapid change, so changeable syndrome, bad syndrome can appear at any time, and an objective and comprehensive grasp of the complexity of the syndrome can help improve the diagnosis and treatment of epidemic disease; the holism of syndrome not only embodied in the human body is a whole, the form of God as a whole, but also emphasised that man and nature are a whole, so more emphasis on man and nature as a whole. The occurrence of epidemics usually due to the unexpected qi appeared not the time, and the holism view of man and nature is an effective way to prevent and control epidemics. With the syndromes as the core, we explored the effective treatment strategy of epidemic disease combined with syndromes to provide ideas for the prevention and control of the epidemics.

RESUMEN
BACKGROUND:Nanostructure modification of pure titanium surface is a hot research field of titanium implant surface treatment. OBJECTIVE:To evaluate the effect of nano-modified titanium surface treated with alkali heat treatment on early adhesion and growth of osteoblasts. METHODS:Four-grade pure titanium sheets with a diameter of 15 mm and a thickness of 1.5 mm were taken and processed in three groups:the smooth treatment group was polished step by step with 250 mesh,800 mesh,and 1 500 mesh silicon carbide sandpaper.In the sandblasting group,the smoothed titanium sheet was sandblasted with 100 μm Al2O3 particles at 0.45 MPa pressure,and then the acid etching was carried out.In the alkali heat treatment group,the smoothed titanium sheet was placed in the reactor,immersed in 10 mol/L NaOH solution,and heated in the oven at 100 ℃for 12 hours.The surface morphology,roughness,and hydrophilicity of three groups of titanium sheets were measured.MG63 osteoblasts were inoculated on the surface of three groups of titanium tablets,and the adhesion of the cells was observed by immunofluorescence staining. RESULTS AND CONCLUSION:(1)Scanning electron microscopy showed that the surface of titanium sheets in the smooth treatment group had uniform scratches;the surface of titanium sheets in the sandblasting group was uneven,and the surface of titanium sheets in the alkali heat treatment group had uniform nanoscale three-dimensional pore morphology.The roughness value of the titanium sheets in sandblasting and alkali heat treatment groups was higher than that in the smooth treatment group(P<0.05),and the water contact angle was lower than that in the smooth treatment group(P<0.05).(2)Immunofluorescence staining after 3 and 6 hours of inoculation of MG63 cells showed that the number of adhesion cells on the surface of the titanium sheet in the sandblasting group and alkali heat treatment group was higher than that in the smooth treatment group(P<0.05).Immunofluorescence staining 12 hours after inoculation showed that compared with the smooth treatment group,the actin skeleton of cells on the surface of titanium sheets in the sandblasting group and alkali heat treatment group was more extended,and most cells extended stronger pseudopodia,which was conducive to subsequent intercellular signal transduction and intercellular interaction.(3)The results showed that the nanostructures with certain biological activity could be prepared on the surface of a titanium sheet by alkali heat treatment,which was conducive to the early adhesion of osteoblasts.
RESUMEN
BACKGROUND:It has been shown that long non-coding RNA(lncRNA)plays an important role in the development and progression of cardiac diseases,and whether it is involved in daisy leaf gentianone antagonizing adriamycin-induced cardiac injury in mice has not been reported. OBJECTIVE:To screen differentially expressed lncRNAs in myocardial tissue of mice with adriamycin-induced myocardial injury antagonized with daisy leaf gentianone and conduct a bioinformatics analysis. METHODS:Forty-eight C57 mice were randomly divided into normal group,model group,daisy leaf gentianone group and positive drug group,with 12 mice in each group.The mice in the model group,daisy leaf gentianone group and positive drug group were injected with adriamycin intraperitoneally once every other day for 8 times in total.The daisy leaf gentianone group and positive drug group were given daisy leaf gentianone suspension and captopril solution by gavage based on adriamycin injection once a day for 21 continuous days.After medication,mice in each group underwent electrocardiogram examination and the myocardial tissue was taken for pathomorphological observation.At the same time,high-throughput sequencing analysis of mouse myocardial tissue was carried out,differentially expressed lncRNAs were screened,and target genes were predicted for differentially expressed lncRNAs.Gene ontology enrichment and Kyoto Encyclopedia of Genes and Genomes signaling pathway analyses of target genes were performed. RESULTS AND CONCLUSION:The ST segment of the electrocardiogram of mice in the model group was significantly elevated.Compared with the model group,the degree of ST-segment elevation on the electrocardiogram was reduced in the daisy leaf gentianone group.Results from hematoxylin-eosin,Masson,and Sirius red staining indicated that in the model group,the myocardial cytoplasm was unevenly colored with varying shades of color,the integrity and continuity of myocardial fibers were poor,and a large number of collagen fibers were deposited.After treatment with gentianone daisy leaves,the abnormalities in myocardial tissue of mice were improved.The results of high-throughput sequencing analysis showed that compared with the model group,a total of 270 lncRNAs were identified in the myocardial tissue of mice in the daisy leaf gentianone group,including 165 up-regulated and 105 down-regulated lncRNAs.Combining the experimental results with related literature,three lncRNAs(NONMMUT149833.1,NONMMUT003237.2,and ENSMUST00000219015)and four related mRNAs(Alas2,Igf2,Acta1,and Cilp)were finally identified.The results of target gene prediction,gene ontology enrichment and Kyoto Encyclopedia of Genes and Genomes signaling pathway analyses showed that differentially expressed lncRNAs in myocardial tissue of mice with myocardial injury could regulate the expression of their target protein-coding genes through cis-and/or trans-regulation,and participate in regulating molecular functions and biological processes.To conclude,daisy leaf gentianone significantly improves cardiac function and partial lncRNA expression in mice with adriamycin-induced myocardial injury.
RESUMEN
Objective To explore the effect of endoplasmic reticulum stress activating transcription factor 6(ATF6)on the expression of reproduction related gene heat shock protein family A member 1 like(HSPA1L)and preliminari-ly clarify its regulatory molecular mechanism.Methods The ATF6 over-expression plasmid was transfected into HEK-293T cells and the over-expression efficiency was verified by RT-qPCR and Western blot.The transcriptome sequen-cing information of testis tissue of male ATF6 knockout mice was used to screen five reproduction related genes down-stream of ATF6.The dual luciferase reporter assay selected the downstream genes with high promoter activity and de-tected the effect of over-expression of ATF6 on the promoter activity of downstream genes.The possible binding sites of ATF6 and downstream gene promoters were predicted by gene-regulation.RT-qPCR and Western blot were used to detect the effect of over-expression of ATF6 on downstream gene expression in HEK-293T cells.Whether ATF6 binds to downstream gene promoters was determined by electrophoretic mobility shift assay(EMSA).Results The expres-sion of ATF6 mRNA(P<0.001)and protein(P<0.001 and P<0.05)in HEK-293T cells was significantly increased after transfection.HSPA1L(P<0.001 and P<0.05),a reproductive related gene downstream of ATF6 was screened by transcriptome sequencing and dual luciferase reporter assay.ATF6 promoted the truncated promoter activity of HSPA1L(P<0.001).After over-expression of ATF6,the expression of HSPA1L was significantly increased(P<0.001).The differences were statistically significant.ATF6 protein could bind to the aagtcgtcac DNA sequence of HSPA1L promoter.Conclusions ATF6,a key molecule of endoplasmic reticulum stress,regulates the expression of reproduction related gene HSPA1L by binding to the promoter of HSPA1L.This result will lay a foundation for further research on the prevention or treatment of endoplasmic reticulum stress(ERS)related male infertility.

Placenta accreta spectrum (PAS) disorders are one of the important causes of adverse pregnancy outcomes. Some studies reported that the limitations in commonly used auxiliary examination methods led to missed or misdiagnosis, resulting in adverse pregnancy outcomes. Digital three-dimensional (3D) reconstruction is the 3D graphical visualization constructed on the original data to illustrate the spatial relationship between structures, overcoming the limitations of two-dimensional images. As a novel auxiliary diagnostic tool, digital 3D reconstruction provides promising insights into the development of personalized precision medicine. This article reviews the research and application of ultrasound and MRI 3D reconstruction in the field of PAS.
RESUMEN
ObjectiveTo provide a reference for the establishment of an ideal corneal neovascularization (CNV) animal model by summarizing the modeling characteristics of CNV animal models. MethodWith "CVN" as the theme word, this paper searched the China National Knowledge Infrastructure (CNKI), Wanfang, Chinese medical journals full-text database, and PubMed database and screened out relevant literature on CNV animal experiments from 2013 to 2023. The database was established by Excel 2021, and the experimental animal strain, gender, modeling method, detection index, and application category were sorted out. The characteristics of the CNV animal model were analyzed. ResultAfter comparative analysis, it was found that the animal strains were Sprague-Dawley rats (87 times, 29.49%) and New Zealand white rabbits (52 times, 17.63%). Male animals were recommended. Most modeling methods for efficacy verification and mechanism studies were the alkali burn method. Index detection methods included apparent index observation, histopathological detection, immunohistochemistry (IHC), Western blot, and various polymerase chain reaction (PCR) tests. Detection indexes included apparent indication, corneal histopathology, CNV regulation, etc. ConclusionThe CNV model of SD rats induced by the alkali burn method is recommended for model replication, and the indexes are mainly selected from the growth of CNV, corneal histopathological test, and vascular endothelial growth factor (VEGF)-related test. In addition, according to the demand, the corneal apparent indication and the basic indexes related to the regulation of CNV, such as vascular endothelial growth factor receptor 2 (VEGFR2), basic fibroblast growth factor (bFGF), and secretogranin Ⅲ (Scg3) are also selected. Clinical treatment of CNV relies on anti-inflammatory drugs and anti-VEGF drugs, and there is a lack of application of traditional Chinese medicine (TCM), so the model needs to be improved by adding elements of TCM syndromes.
