Background and aims Hepatocellular carcinoma (HCC) cells are metabolically reprogrammed for excessive uptake and metabolism of many nutrients. The tumor suppressive microRNA-148a-3p (miR-148a-3p) is downregulated in HCC, whereas its function in regulating HCC cell metabolism remains obscure. Herein we aimed to delineate the role of miR-148a-3p in HCC cell metabolism by using novel bioengineered miR-148a-3p (BioRNALeu/miR-148a-3p) agent produced in vivo. Methods BioRNALeu/miR-148a-3p was designed by using human leucyl transfer RNA fused hsa-pre-miR-34a carrier, overexpressed in Escherichia coli (E. coli), and purified to high homogeneity. After transfection into HCC cells, the released miR-148a-3p levels were assessed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Cell proliferation was determined by CellTiter-Glo assays. Targets were validated by dual-luciferase reporter assays, immunoblotting, and immunofluorescence confocal imaging. Glycolysis capacity was evaluated by Seahorse XF assays, and glucose, lactate, and amino acid levels were quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods. Results BioRNALeu/miR-148a-3p was efficiently processed into target miR-148a-3p in HCC cells to effectively inhibit cell proliferation in a dose- and time-dependent manner. Mechanistically, miR-148a-3p suppressed the protein levels of glucose transporter GLUT1/SLC2A1 and L-type amino acid transporter LAT1/SLC7A5 via acting on their 3′-untranslated regions, as well as amino acid transporter ASCT2/SLC1A5. These, in turn, led to a reduction of glucose uptake, lactate production, and glycolytic flux in HCC cells, and alteration of intracellular amino acid metabolome including glutamine, leucine, phenylalanine, tyrosine, and methionine. Conclusions Reintroduction of miR-148a-3p into HCC cells modulates glucose and amino acid metabolism via regulating multiple SLC transporters, thereby suppressing HCC cell viability. These findings highlight the role of miR-148a-3p in HCC cell metabolism and potential of bioengineered miRNA molecules for functional studies and therapeutic development.

OBJECTIVE To explore the current status,etiological characteristics and risk factors for nosocomial in-fections in the patients who are treated with extracorporeal membrane oxygenation(ECMO)so as to provide bases for treatment and prevention of nosocomial infections in the ICU patients treated with ECMO.METHODS The clinical data were retrospectively collected from the patients who were treated with ECMO in the ICU of Xinyang Central Hospital from Jan.2021 to Dec.2023.The patients were divided into the infection group and the non-infec-tion group according the status of nosocomial infection during the ECMO treatment period.The constituent ratios of pathogens isolated from the patients with infections were recorded,and multivariate logistic regression analysis was performed for independent risk factors for the ECMO-related nosocomial infections.RESULTS Of 86 patients who were finally enrolled in the study,33(38.37％)had nosocomial infections.Totally 54 strains of pathogens were isolated from the patients with the infections,43(79.63％)of which were gram-negative bacteria,7(12.97％)were gram-positive bacteria,and 4(7.41％)were fungi.There were 36(66.67％)strains of multi-drug-resistant organisms(MDROs)among the 54 strains of pathogens,and 27(81.82％)patients were detected with MDROs.Among the ECMO patients with postoperative nosocomial infections,21(63.64％)cases had pul-monary infections,8(24.24％)cases had bloodstream infection,and 4(12.12％)had urinary system infections.Multivariate logistic analysis showed that the high blood glucose level at the beginning of treatment with ECMO,long duration of ECMO treatment and long time of central venous catheter indwelling were the independent risk factors for the nosocomial infections in the patients treated with ECMO(P＜0.05).CONCLUSION The isolation rate of gram-negative bacteria is relatively high among the pathogens isolated from the ECMO patients with post-operative nosocomial infections,and the drug resistance rates are high.The high blood glucose level,long duration of ECMO supporting treatment and long time of central venous catheter indwelling are the independent risk factors for the nosocomial infections in the patients treated with ECMO.

Objectives:To analyze the 100 most cited papers in the field of spino-pelvic sagittal balance since 2003,summarize and sort out the research hotspots and trends by using bibliometrics,in order to pro-vide references for related research and disease diagnosis and treatment in this field.Methods:The English literature in the field of spino-pelvic sagittal balance published from 2003 to 2023 was searched in the Web of Science Core Collection(WoSCC)database.According to the inclusion and exclusion criteria,the keywords,publication year,first author,publishing institution,country,publication journal,and total number of citations of the included literature were extracted for summary and visual analysis.VOSviewer,CiteSpace,RStudio and other bibliometric analysis tools were used to reveal the global trends and research hotspots in this field.Results:A total of 6804 articles were retrieved according to the search criteria set in this study.Based on the title,abstract and full text of the articles,the top 100 most cited articles were finally obtained,including 86 original articles and 14 reviews.58 articles were published between the year 2003 and 2019,and cited 200 times or more.The most cited article was"The impact of positive sagittal balance in adult spinal defor-mity",with a total of 1179 citations.The country with the largest number of publications was the United States.The journal published the most articles was Spine.The most published institution was the University of Washington.The most prolific first author was Lafage V.Balance was the most frequent keyword.After reading the full text,the topics of the literature were summarized into seven aspects:radiological parameters,surgery,complications,classification system,general overview,compensation mechanism and others.Conclu-sions:Radiological parameters,surgery,and complications are still the focus of current research.Minimally invasive surgical techniques and individualized treatment are the future research and development trends.The number of articles published by Chinese scholars is increasing,while the number of citations is relatively small.

Colorectal cancer(CRC)is the most common malignant tumor of the digestive tract,with its incidence rate increasing annually and showing a younger-age trend,imposing heavy health and economic burdens on society and families.Regular moderate-to-vigorous physical exercise has been demonstrated to significantly reduce the risk of developing CRC,alleviate complications and adverse reactions related to anti-tumor treatment,improve patients'quality of life,and prolong survival.As a simple and economical non-pharmacological intervention,exercise plays a crucial role throughout CRC development and treatment by regulating inflammatory signals and promoting anabolic metabolism through multi-omics regulatory networks.This article reviewed the latest evidence from clinical and experimental studies,emphasizing the indispensability of exercise in the comprehensive management of CRC patients,and provided a summary analysis of relevant mechanisms.Future research should further investigate the specific impacts of various exercise types,intensities,and frequencies on CRC,combine them with clinical treatment methods such as radiotherapy and chemotherapy,and explore precision approaches under multimodal interventions to maximize clinical benefits.
