Abstract
Objective: To analyze the differences between trans-radial access (TRA) and trans-femoral access (TFA) in hepatic arterial perfusion chemotherapy (HAIC) in terms of patient experience, postoperative complications, and patient preferences; explore whether TRA in HAIC is associated with better patient experience and compliance; and determine whether it is safer than TFA. Methods: The study was a retrospective cohort study of patients with advanced hepatocellular carcinoma and liver metastases from colorectal cancer treated with HAIC. We enrolled a total of 91 patients with advanced liver malignancies treated with HAIC from November 2022 to May 2023 in the Department of Interventional Therapy and Hepatobiliary Medicine at Tianjin Medical University Cancer Hospital. The patients were divided into three groups: group TRA (n=20, receiving TRA HAIC only), group TFA (n=33, receiving TFA HAIC only), and crossover group [n=19, receiving TFA HAIC (Cross-TFA group) first, followed by TRA HAIC (Cross-TRA group)]. Meanwhile, to facilitate the expression of partial results, all patients receiving TRA HAIC were defined as the TRA-HAIC group (n=39, TRA+Cross-TRA group), and all patients receiving TFA HAIC were defined as the TFA-HAIC group (n=52, TFA+Cross-TFA group). The primary research index was the Quality of Life (QOL) visualization scale score. The secondary research index included approach-related and catheter-related adverse events, duration of surgery, and mean length of patient stay. We used various statistical methods such as Mann-Whitney U test, t-test, Chi-square test, Fisher's exact test, univariate logistic regression analysis, and multi-factor analysis. Results: TRA patients had significantly lower QOL scores than TFA patients (all P<0.001). The QOL scores of the Cross-TRA group were significantly lower than those of the Cross-TFA group (pain at the puncture site Z=-3.24, P=0.001, others P<0.001). The QOL scores of the Cross-TRA group were compared with those of the TRA group, which showed that the scores of the Cross-TRA group in overall discomfort (Z=-3.07,P=0.002), postoperative toilet difficulty (Z=-2.12, P=0.034), and walking difficulty (Z=-2.58, P=0.010) were significantly lower than those of the TRA group. Satisfaction scores were significantly higher in the Cross-TRA group than in the Cross-TFA group (Z=-3.78, P<0.001), and patients were more likely to receive TRA HAIC as the next procedure (χ2=30.42, P<0.001). In terms of mean length of stay, patients receiving TRA HAIC had a significantly lower mean length of stay than those receiving TFA HAIC (50.1±3.2 h vs. 58.4±6.4 h, t=7.98, P<0.001). The incidence of radial artery occlusion (RAO) as an approach-related adverse event was 15.4% (6/39) in the TRA-HAIC group, which was significantly higher than that in the TFA-HAIC group (15.4% vs. 0, χ2=8.56, P=0.005). Notably, multifactorial analysis of RAO-related factors showed that intraoperative enoxaparin use and patency of radial artery flow during pressure were significantly associated with a reduced risk of postoperative RAO (P=0.037 for enoxaparin use and P=0.049 for pressure). Conclusions: With respect to procedure approach, TRA was significantly better than TFA in terms of patient satisfaction and mean length of stay. Through further process optimization and prevention of adverse reactions, the incidence of adverse reactions can be maintained at a relatively low level, so that patients can benefit from TRA in future operations in terms of cost-effectiveness and medical efficiency.

Abstract
The efficiency of persulfate-assisted advanced oxidation processes (PS-AOPs) in degrading organic pollutants is affected by the electron-donating capability of organic substances present in the water source. In this study, we systematically investigate the electron-donating capacity (EDC) difference between groundwater and surface water and demonstrate the dependence of removal efficiency on the EDC of target water by PS-AOPs with carbon nanotubes (CNTs) as a catalyst. Laboratory analyses and field experiments reveal that the CNT/PS system exhibits higher performance in organic pollutant removal in groundwater with a high concentration of phenols, compared to surface water, which is rich in quinones. We attribute this disparity to the selective electron transfer pathway induced by potential difference between PS-CNT and organic substance-CNT intermediates, which preferentially degrade organic substances with stronger electron-donating capability. This study provides valuable insights into the inherent selective removal mechanism and application scenarios of electron transfer process-dominated PS-AOPs for water treatment based on the electron-donating capacity of organic pollutants.

Abstract
Dentition defects damage the integrity of the dental arch, affecting smile esthetics and oral function. Compared to restorative treatment, pre-restoration orthodontic treatment overcomes the limitations of a single method, effectively avoiding excessive wear of natural teeth, reducing the number of units for restorative production to a certain extent, and potentially improving facial shape and occlusal relationship, which maximizes the therapeutic effect. This article explores the key points of pre-restoration orthodontic treatment for different types of dentition defects in terms of malocclusion manifestations, treatment objectives, treatment methods, and maintenance recommendations from the perspective of combined orthodontic restoration treatment.

Abstract
Electrocatalytic reduction of ethylenediamine tetraacetic acid copper (CuEDTA), a typical refractory heavy metal complexation pollutant, is an environmental benign method that operates at mild condition. Unfortunately, the selective reduction of CuEDTA is still a big challenge in cathodic process. In this work, we report a MoS2 nanosheet/graphite felt (GF) cathode, which achieves an average Faraday efficiency of 29.6% and specific removal rate (SRR) of 0.042 mol/cm2/h for CuEDTA at - 0.65 V vs SCE (saturated calomel electrode), both of which are much higher than those of the commonly reported electrooxidation technology-based removal systems. Moreover, a proof-of-concept CuEDTA/Zn battery with Zn anode and MoS2/GF cathode is demonstrated, which has bifunctions of simultaneous CuEDTA removal and energy output. This is one of the pioneer studies on the electrocatalytic reduction of heavy metal complex and CuEDTA/Zn battery, which brings new insights in developing efficient electrocatalytic reduction system for pollution control and energy output.

Abstract
The heterogeneous Fenton-like reaction (HeFR) has always been a research focus for environmental applications. However, it has long been difficult to reach a consensus on the reaction mechanism because the process of metal ions dissolution and its role were not well understood. In this paper, we propose the courses of organics-mediated coordination or/and reduction dissolution of ferric hydroxide to initiate the autocatalytic kinetics of phenol degradation and illustrate it through density functional theory (DFT) and experiments. With the increase of hydrogen peroxide concentration, the degradation of phenol changes from autocatalytic kinetics to first-order kinetics. Furthermore, a novel "limit segmentation method" initiated by us indicates that homogeneous reaction plays a decisive role in the phenol degradation process. The dominant roles of the reactive organics in both iron dissolution and the iron cycle and of the homogeneous reaction in the whole degradation process in the ferric hydroxide-based HeFR system are brand-new insights that pave the pathway for future research.

Abstract
Antibiotic residues cause increasing concern in environmental ecology and public health, which needs efficient analysis strategy for monitoring and control. In this study, a fast, specific, and ultrasensitive sensor based on field-effect transistor (FET) has been proposed for the detection of ampicillin (AMP). The sensor involves monolayer tungsten disulfide (WS2) nanosheet as the sensing channel, single-stranded DNA (ssDNA) as the sensing probe, and gold nanoparticle (Au NP) as the linker. The WS2/Au/ssDNA FET sensor responds rapidly to AMP in a wide linear detection range (10-12-10-6 M) and has low limit of detection (0.556 pM), which meets the permissible standards of AMP in water and food. The sensing mechanism study suggests that the excellent sensor response results from the increased number of negative charges in the Debye length and the consequent accumulation of holes in WS2 channel after the addition of AMP. Moreover, satisfactory sensing performance was confirmed in real water samples, indicating the potential application of the proposed method in practical AMP detection. The reported FET sensing strategy provides new insights in antibiotic analysis for risk assessment and control.

Abstract
Abstract
Aims
Sex refers to genetic and biological characteristics, whereas gender reflects psychosocial norms, roles and behaviors. Sex differences in new-onset heart failure are well described, but gender differences in new-onset heart failure with preserved (HFpEF) and reduced left ventricular ejection fraction (HFrEF) are unknown.
Methods
A total of 6830 participants (50.3% women, mean age of 54 years) from the Prevention of Renal and Vascular End-Stage Disease (PREVEND) observational Dutch cohort were enrolled in the study. Gender-related characteristics were assessed using self-administered questionnaires. LASSO regression analysis selected the psychosocial variables related to sex, whose coefficient estimates were used to calculate the gender-related scores for each subject [1–2]. The participants were grouped by sex and further analyzed according to tertiles of the gender-related score. Competing-risk regression analysis was used to assess whether sex and gender were associated with new-onset HFrEF (LVEF ≤40%) and HFpEF (LVEF ≥50%).
Results
Women with predominantly masculine gender had lower BMI, were more often Caucasian and had higher total cholesterol and high-density lipoprotein (HDL) levels than women with a predominantly feminine gender. Men with predominantly feminine gender were less often Caucasian with lower total cholesterol and HDL cholesterol levels than men with a predominantly masculine gender. During a median follow-up of 8.3 years, 227 (3.3%) subjects were diagnosed with heart failure (57.3% HFrEF and 43.7% HFpEF). In the total population including both men and women, feminine gender was significantly and independently associated with a higher risk of new-onset HFpEF compared with masculine gender (HR per 10 point: 1.17, 95% CI: 1.06–1.30; p=0.003). However, sex was not associated with new-onset HFpEF (HR: 1.09, 95% CI: 0.73–1.62; p=0.670). Separately in men, feminine gender was associated with a higher risk of new-onset HFpEF (HR: 1.37, 95% CI: 1.06–1.78; p=0.017), but not in women (HR: 1.13, 95% CI: 0.90–1.41; p=0.310).
Conclusions
Gender and sex are different constructs and feminine gender was associated with an increased risk of new-onset HFpEF, whereas sex was not associated with new-onset HFpEF.

Abstract
Objectives: To evaluate the effects of steatotic donor livers on the safety of donors and the prognosis of donors and recipients in pediatric living donor liver transplantation. Methods: A total of 814 pediatric living donor liver transplantations were performed between January 2013 and December 2020 at Department of Pediatric Organ Transplantation,Tianjin First Central Hospital.The clinical data were collected and a retrospective study was conducted.The recipients and the donors were divided into non-steatotic donor liver group(n=733) and steatotic donor liver group(n=81) according to whether the donor graft had steatosis. The recipients and the donors in the steatotic donor liver group were further divided into mild and moderate steatosis groups based on the degree of liver steatosis.Among the donors of non-steatosis donor group,there were 307 males and 426 females,with a median age of 30 years(range:18 to 57 years);the recipients included 351 males and 382 females,with a median age of 7 months(range:4 month to 14 years).Among the donors of steatosis donor group,there were 41 males and 40 females,with a median age of 31 years(range:22 to 51 years);the recipients included 34 males and 47 females,with a median age of 8 months(range:5 months to 11 years).The donors and the recipients were followed up regularly by means of outpatient reexamination and questionnaire survey after operation.Statistical analysis of data between groups was performed using t-test,Wilcoxon rank-sum test,repeated measures ANOVA,χ2 test,or Fisher's exact test,respectively.The survival curves of recipients and grafts in different groups were created by Kaplan-Meier method,and the survival rates of the steatotic donor liver group and the non-steatotic donor liver group were compared by Log-rank method. Results: There was no significant difference in the gender of donors in both groups (P=0.132).There were significant differences in the age and blood type distribution as well as body weight and body mass index(all P<0.05) between the two groups.No significant difference was seen in the recovery of liver function markers ALT and AST at 1,2,5 days and 1 month after operation (all P>0.05) between the two groups.The steatotic donor liver group showed longer operation time ((294±75) minutes vs. (264±81) minutes; t=3.149,P=0.002),increased incidence of postoperative biliary leakage (3.7%(3/81) vs. 0.5% (4/733); P=0.025) and delayed incision healing (7.4%(6/81) vs. 2.0%(15/733); P=0.013).There were no significant differences in gender,age,blood type distribution,height,weight and pediatric end-stage liver disease score of recipients between the two groups (all P>0.05).As compared to the non-steatotic donor liver group,the steatotic donor liver group showed similar levels of ALT, AST and total bilirubin within 2 weeks after operation(all P>0.05). The cumulative recipient survival rates in both groups were both 96.3%,the cumulative graft survival rates were 96.3% and 95.5%,respectively,without significant difference(both P>0.05). No statistical difference was observed in the incidence of major complications between the two groups (all P>0.05). There was no significant difference in the recovery of liver function markers of donors and recipients between mild and moderate steatosis groups(all P>0.05).The cumulative recipient survival rates were both 95.9% and the cumulative graft survival rates were both 100% in mild and moderate steatosis groups,without significant difference(P=0.592). Conclusions: The application of mild to moderate steatotic donor livers in pediatric living donor liver transplantation may prolong the operation time of donors,increase the incidence of complications such as biliary leakage and delayed incision healing. But there is no significant impact of mild to moderate steatotic donor livers on the overall postoperative recovery of donors and recipients,and the prognosis is ideal.

Abstract
PURPOSE Fibrosis is the only histological feature reflecting the severity and prognosis of nonalcoholic steatohepatitis (NASH). We aim to explore novel genes associated with fibrosis progression in NASH. METHODS Two human RNA-seq datasets were downloaded from the public database. Weighted gene co-expression network analysis (WGCNA) was used to identify their co-expressed modules and further bioinformatics analysis was performed to identify hub genes within the modules. Finally, based on two single-cell RNA-seq datasets from mice and one microarray dataset from human, we further observed the expression of hub genes in different cell clusters and liver tissues. RESULTS 7 hub genes (SPP1, PROM1, SOX9, EPCAM, THY1, CD34 and MCAM) associated with fibrosis progression were identified. Single-cell RNA-seq analysis revealed that those hub genes were expressed by different cell clusters such as cholangiocytes, natural killer (NK) cells, and hepatic stellate cells (HSCs). We also found that SPP1 and CD34 serve as markers of different HSCs clusters, which are associated with inflammatory response and fibrogenesis, respectively. Further study suggested that SPP1, SOX9, MCAM and THY1 might be related to NASH-associated hepatocellular carcinoma (HCC). Receiver operating characteristic (ROC) analysis showed that the high expression of these genes could well predict the occurrence of HCC. At the same time, there were significant differences in metabolism-related pathway changes between different HCC subtypes, and SOX9 may be involved in these changes. CONCLUSIONS The present study identified novel genes associated with NASH fibrosis and explored their effects on fibrosis from a single-cell perspective that might provide new ideas for the early diagnosis, monitoring, evaluation, and prediction of fibrosis progression in NASH.

Abstract
We report an electrolysis system using NiFe layered double hydroxide/CoMoO4/nickel foam (NFLDH/CMO/NF) as the anode and CMO/NF as the cathode for simultaneous phenol electro-oxidation and water electrolysis. This system shows high performance for both phenol degradation and hydrogen evolution. We demonstrate that the degradation rate of phenol on the active anode is governed by the mass transfer rate at a low phenol concentration (0.5-2 mM) and by the electro-oxidation rate at a high phenol concentration (5 mM). The anodic oxygen evolution reaction (OER) can promote the phenol degradation through enhanced mass transfer efficiency. More importantly, the common deactivation issue of phenol electro-oxidation on the inert anode can be eliminated by the high OER activity of the active anode. The constructed full electrolytic cell only needs a low potential of 1.498 V to achieve 10 mA/cm2 for water electrolysis. The reported promotion effect of phenol degradation by OER as well as the improved anode resistance to deactivation offer new insights into efficient and robust waste-to-resource electrolysis system for water treatment.

Abstract
Background Gut microbes degrade and ferment resistant starch (RS) into metabolites that help maintain gut homeostasis. Clinical trials have evaluated RS for various health conditions, but individuals respond to RS with profound variability. The reason for this variability is unclear. Aims Using in vitro culturing methods and multi-omic analyses, we hypothesize that individuals will elicit variable responses to RS with respect to overall fermentation, bacterial composition, short chain acid production, and metabolite flux. Methods As part of an ongoing clinical trial, we have selected 4 pediatric patients with inflammatory bowel disease to better understand microbiome-RS interactions. We cultured stools anaerobically using a high-throughput platform (“RapidAIM”) with 9 different pre-digested RS. After 18-hour incubations, media supernatants were used to measure pH and perform targeted and semi-targeted metabolomic analyses with a panel of 116 compounds. Bacterial pellets were isolated for 16S rRNA gene sequencing analyses to evaluate changes in microbiome compositions. Data were analyzed with generalized linear mixed models, principal component analysis (PCA), random forest (RF) classification with feature selection, and network construction with graphical lasso. Results Changes in several microbiome parameters were different across individuals, including the magnitude of pH changes, metabolite signatures, and relative abundances of important bacterial taxa. Bacterial species known to degrade RS were more abundant in individuals showing stronger RS fermentation. Inter-individual discrimination was accomplished with PCA and RF, from which we could identify metabolite signatures. The robustness of microbiome networks corresponded to RS fermentation and butyrate production. Conclusions We report a novel perspective on how individuals respond to RS’ differently. Butyrate remains an important hub of the microbiome architecture with respect to RS fermentation. Future work will interrogate the roles of individualized metabolomic responses on host physiology. In vivo responses to RS are being evaluated in an ongoing clinical trial. Funding Agencies CCC, CIHRGenome Ontario, Genome Canada

Abstract
Selective removal of organic pollutants by advanced oxidation methods has been receiving increasing attention for environmental remediation. In this study, a novel catalyst, which can selectively oxidize phenolic compounds (PCs) based on their hydrophobicity, composed of metal-organic-framework-derived Fe/Fe3O4 and three-dimensional reduced graphene oxide (rGOF) is designed for peroxydisulfate (PDS) activation. This heterogeneous PDS activation system can completely degrade hydrophobic PCs within 30 min. By investigating the hydrophobic properties of eight representative PCs, a positive correlation between the hydrophobicity of PC and the reaction kinetics is reported for the first time. The selective removal stems from the strong interaction between highly hydrophobic PCs and the catalyst. Moreover, the mechanism investigation shows that the degradation reaction is triggered by interface reactive oxygen species (ROS). Our study reveals that the selective degradation of organic pollutants by PDS activation depends on the hydrophilic and hydrophobic properties of the pollutant and catalyst. The reported results provide new insights into a highly selective and efficient PDS activation system for organic pollutant removal.

Abstract
AIM To establish an ultrasound-based radiomics model through machine learning methods and then to assess the ability of the model to differentiate infected focal liver lesions from malignant mimickers. MATERIALS AND METHODS A total of 104 patients with infected focal liver lesions and 485 patients with malignant hepatic tumours were included, consisting of hepatocellular carcinoma (HCC), cholangiocarcinoma (CC), combined hepatocellular-cholangiocarcinoma (cHCC-CC), and liver metastasis. Radiomics features were extracted from grey-scale ultrasound images. Feature selection and predictive modelling were carried out by dimensionality reduction methods and classifiers. The diagnostic effect of the prediction mode was assessed by receiver operating characteristic (ROC) curve analysis. RESULTS In total, 5,234 radiomics features were extracted from grey-scale ultrasound image of every focal liver lesion. The ultrasound-based radiomics model had a favourable predictive value for differentiating infected focal liver lesions from malignant hepatic tumours, with an area under the curve (AUC) of 0.887 and 0.836 (HCC group), 0.896 and 0.766 (CC group), 0.944 and 0.754 (cHCC-CC group), 0.918 and 0.808 (liver metastasis group), and 0.949 and 0.745 (malignant hepatic tumour group) for the training set and validation set, respectively. CONCLUSIONS Ultrasound-based radiomics is helpful in differentiating infected focal liver lesions from malignant mimickers and has the potential for use as a supplement to conventional grey-scale ultrasound and contrast-enhanced ultrasound (CEUS).

Abstract
Mercury is one of the leading chemicals of concern and receives much attention in environmental safety. It is of great necessity to develop advanced Hg2+ analysis method for rapid detection and monitoring. Field-effect transistor (FET) sensor, an emerging electronic sensor, has received great attention in environmental analysis since it has unique advantages in achieving rapid analysis of chemicals. Herein, an FET sensor is constructed with Ti3C2Tx MXene as the channel material to detect Hg2+ in water. The sensor displays rapid and selective response to Hg2+. Moreover, the sensor achieves satisfactory performance in Hg2+ detection in high salinity environment (1 M NaCl), which benefits its applications in real water analysis. Based on the investigation of sensing mechanism, the strong response of Ti3C2Tx MXene FET sensor to Hg2+ is due to the adsorption and reduction of Hg2+ to Hg+ on the Ti3C2Tx surface. This reported label-free Ti3C2Tx MXene platform can detect Hg2+ in high salinity environment with high specificity, which has significant application potential for on-site monitoring and risk assessment of Hg2+ in aqueous systems.

Abstract
Magnonics is a budding research field in nanomagnetism and nanoscience that addresses the use of spin waves (magnons) to transmit, store, and process information. The rapid advancements of this field during last one decade in terms of upsurge in research papers, review articles, citations, proposals of devices as well as introduction of new sub-topics prompted us to present the first roadmap on magnonics. This is a collection of 22 sections written by leading experts in this field who review and discuss the current status besides presenting their vision of future perspectives. Today, the principal challenges in applied magnonics are the excitation of sub-100 nm wavelength magnons, their manipulation on the nanoscale and the creation of sub-micrometre devices using low-Gilbert damping magnetic materials and its interconnections to standard electronics. To this end, magnonics offers lower energy consumption, easier integrability and compatibility with CMOS structure, reprogrammability, shorter wavelength, smaller device features, anisotropic properties, negative group velocity, non-reciprocity and efficient tunability by various external stimuli to name a few. Hence, despite being a young research field, magnonics has come a long way since its early inception. This roadmap asserts a milestone for future emerging research directions in magnonics, and hopefully, it will inspire a series of exciting new articles on the same topic in the coming years.

Abstract
Objectives: To study the risk factors for massive intraoperative blood loss in children with biliary atresia who underwent liver transplantation for the first time,and to analyze their impacts on graft survival,hospital stay and postoperative complications. Methods: The data of 613 children with biliary atresia who underwent liver transplantation at Department of Pediatric Organ Transplantation,Tianjin First Central Hospital from January 2015 to December 2018 were collected and analyzed. There were 270 males and 343 females, aged 7.4 (3.9) months (range: 3.2 to 148.4 months), the body weight of the recipients were (7.8±3.5) kg (range: 4.0 to 43.3 kg).According to the 85th quad of estimated blood loss(EBL),they were divided into two groups:massive EBL group(96 cases) and non massive EBL group(517 cases). The age,height,weight and other factors between the two groups were analyzed and compared. Univariate Logistic regression and multiple stepwise regression were used to determine the risk factors of massive EBL. Then,the postoperative complications of the two groups,including portal vein thrombosis and portal vein anastomotic stenosis etc.,were analyzed and compared by chi square test. Kaplan Meier curve and log rank test were used to analyze the recipient and graft survival rate of the two groups. Results: During the study period,713 transplants were performed and 613 patients were enrolled in the study. Ninety-six patients(15.7%) had massive EBL,and the postoperative hospital stay was 21(16) days(range:2 to 116 days),the hospital stay of non-massive EBL group was 22(12)days(range:3 to 138 days)(U=24 224.0,P=0.32). Univariate Logistic regression analysis showed that the recipient's weight,Kasai portoenterostomy,platelet count,operation time and cold ischemia time were the risk factors of massive EBL during biliary atresia transplantation. Multiple regression analysis showed that cold ischemia time ≥10 hours,prolonged operation time(≥8 hours) and body weight<5.5 kg were important independent risk factors for massive EBL.The incidence of portal vein thrombosis,hepatic vein stenosis,intestinal leakage and pulmonary infection in patients with massive EBL were significantly higher than those without massive EBL(3.1% vs. 0.8%,9.4% vs. 2.1%,6.3% vs. 0.8%,30.2% vs. 20.1%,all P<0.05). The 3-year overall graft and recipient survival rate were significantly lower in patients with massive EBL than those without massive EBL(87.5% vs. 95.7%,P=0.001;84.4% vs. 95.4%,P<0.01,respectively). Conclusions: In children with biliary atresia who underwent liver transplantation for the first time,the effective control of intraoperative bleeding should shorten the operation time and reduce the cold ischemia time as far as possible,on the premise of ensuring the safety of operation. For children without growth disorder,the weight of children should be increased to more than 5.5 kg as far as possible to receive the operation. Reducing intraoperative bleeding is of great significance to the prognosis of children.

Abstract
OBJECTIVE Lung cancer is one of the most malignant tumors with high morbidity and mortality in the world. The incidence and mortality of lung cancer were increased per year in many countries over the past 50 years. The increasing studies had shown that circular RNA (circRNA) was involved in the progression of lung cancer. Therefore, it was significant to seek the molecular mechanism of circ_0012673 in lung cancer. MATERIALS AND METHODS Real-time quantitative polymerase chain reaction (RT-qPCR) was performed to estimate the expression levels of circ_0012673, miR-320a and LIM domain kinase 1 (LIMK1) in lung cancer tissues and cells. 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazol-3-ium bromide (MTT), flow cytometry and transwell assays were recruited to evaluate proliferation, apoptosis and mobility of lung cancer cells, respectively. The relative protein expression levels of Vimentin, N-cadherin, E-cadherin and LIMK1 were determined with Western blot assay. The relationships among circ_0012673, miR-320a and LIMK1 were analyzed by starBase database, dual-luciferase reporter assay, and Pearson's correlation. RESULTS Circ_0012673 was overexpressed in lung cancer tissues and cell lines. Loss-of-functional experiment confirmed that knockdown of circ_0012673 constrained proliferation, motility and Epithelial-Mesenchymal Transition (EMT), but induced apoptosis by targeting miR-320a. Furthermore, LIMK1 was a target of miR-320a in lung cancer cells. Elevated LIMK1 could abolish the overexpression of miR-320a induced effects on lung cancer cells. Mechanistically, circ_0012673 contributed to lung cancer progression through mediating miR-320a /LIMK1 pathway. CONCLUSIONS Circ_0012673 was a tumor-promoter in lung cancer via acting as competing endogenous RNA to regulate LIMK1 expression by binding miR-320a.

Abstract
Objective: To summarize the clinical characteristics of high-risk neuroblastoma (HR-NB) in a single center, analyze the prognostic factors of HR-NB. Methods: The clinical data of children with HR-NB who were treated and followed up at the hematology-oncology center of Beijing Children's Hospital from February 1, 2007 to June 30, 2018 were analyzed retrospectively. The clinical features were summarized. Kaplan-Meier method was used for survival analysis and Cox regression was used to analyze the prognostic factors. The last follow-up time was June 30, 2019. Results: A total of 458 children with HR-NB were enrolled in this study, including 265 males (57.9%) and 193 females (42.1%), the age at diagnosis was 40.0 months (4.5-148.0 months), the follow-up time was 22.0 months (0.2-138.0 months) and the time of tumor progression or recurrence was 15 months (1-72 months). The 5-year event-free survival (EFS) rate was (31.2±2.6)% and the 5-year overall survival (OS) rate was (43.9±3.2)%. The 5-year EFS rate and 5-year OS rate in 142 hematopoietic stem cell transplantation (HSCT) patients with bone marrow metastases were better than that in 196 non-transplantation cases with bone marrow metastases ((26.5±4.5)% vs. (25.1±3.6)%, χ²=13.773, P=0.001; (38.1±5.5)% vs. (35.7±4.7)%, χ²=9.235, P=0.002); 128 transplantation patients with bone metastases had higher 5-year EFS rate and 5-year OS rate than 188 non-transplantation cases with bone metastases ((28.5±5.0)% vs. (26.7±3.8)%, χ²=10.222, P=0.001; (37.1±6.0)% vs. (36.2±4.8)%, χ²=7.843, P=0.005). The 5-year EFS rate was higher in 37 HSCT patients with MYCN amplification than in 49 non-transplantation cases with MYCN amplification ((26.8±8.0) % vs. (20.5±6.4) %, χ²=5.732, P=0.017). No significant difference was found in 5-years OS rate between transplantation group with MYCN amplification and non-transplantation group with MYCN amplification ((31.4±8.6) % vs. (26.2±7.4) %, χ²=3.230, P=0.072). Univariate survival analysis showed that lactate dehydrogenase (LDH)≥1 500 U/L was associated with poor prognosis of patients with MYCN amplification (χ²=6.960, P=0.008). Multivariate Cox analysis showed bone marrow metastasis and LDH≥1 500 U/L were independent risk factors for poor prognosis of patients with non-MYCN amplification (HR=2.427, 1.618;95%CI:1.427-4.126, 1.275-2.054, P<0.05) for both comparisons. Conclusions: LDH≥1 500 U/L was the poor prognostic factor for patients with MYCN amplification. The bone marrow metastasis and LDH≥1 500 U/L were the poor prognostic factors for HR-NB patients with non-MYCN amplification. HSCT can improve the prognosis of patients with bone or bone marrow metastasis. It can also retard the time of progression or recurrence for patients with MYCN amplification.

Abstract
AIMS Mitochondrial dysfunction is involved in the pathogenesis of type 2 diabetes. Glutathione S-transferase kappa 1 (GSTK1) is critical to maintain mitochondrial function and homeostasis. We aimed to investigate whether a potential link exists between mitochondrial DNA (mtDNA) copy numbers and inflammation, non-esterified fatty acids (NEFA) and GSTK1 expression in type 2 diabetes. METHODS We assessed mtDNA copy numbers in plasma and GSTK1 expression in white blood cells in 123 people with type 2 diabetes and in 121 healthy controls using a quantitative polymerase chain reaction (qPCR). An automatic chemistry or immunoassay analyser was used to determine serum glucose, lipids and inflammatory markers. Multiple linear regression and multivariable logistic regression models were used to evaluate associations and risks. RESULTS Compared with healthy controls, individuals with diabetes showed higher mtDNA copy numbers (t = -3.938, P < 0.001) and lower GSTK1 expression (Z = -2.985, P = 0.002). mtDNA copy number was associated with type 2 diabetes risk [odds ratio (OR) = 1.80, 95% confidence intervals (CI) 1.25-2.58, P = 0.001] after controlling for confounding factors. In individuals with diabetes, mtDNA copy number was negatively associated with GSTK1 expression (β = -0.235, P = 0.036) and positively associated with serum high-sensitive C-reactive protein (hsCRP) (β = 0.839, P < 0.001), tumour necrosis factor alpha (TNF-α) (β = 0.549, P < 0.001), interleukin-6 (IL-6) (β = 0.589, P = 0.006) and NEFA (β = 0.001, P = 0.020). In the diabetic group, individuals with an abnormal increase in NEFA, hsCRP, TNF-α and IL-6 showed significantly elevated mtDNA copy numbers (all P < 0.05). CONCLUSIONS mtDNA copy numbers in plasma might have an important role in the progression of diabetic chronic inflammation via inhibition of GSTK1 and could be a potential biomarker for type 2 diabetes.

Abstract
The pyruvate oxidase (SpxB)-dependent production of H2O2 is widely distributed among oral commensal streptococci. Several studies confirmed the ability of H2O2 to antagonize susceptible oral bacterial species, including caries-associated Streptococcus mutans as well as several periodontal pathobionts. Here we report a potential mechanism to bolster oral commensal streptococcal H2O2 production by magnesium (Mg2+) supplementation. Magnesium is a cofactor for SpxB catalytic activity, and supplementation increases the production of H2O2 in vitro. We demonstrate that Mg2+ affects spxB transcription and SpxB abundance in Streptococcus sanguinis and Streptococcus gordonii. The competitiveness of low-passage commensal streptococcal clinical isolates is positively influenced in antagonism assays against S. mutans. In growth conditions normally selective for S. mutans, Mg2+ supplementation is able to increase the abundance of S. sanguinis in dual-species biofilms. Using an in vivo biophotonic imaging platform, we further demonstrate that dietary Mg2+ supplementation significantly improves S. gordonii oral colonization in mice. In summary, our results support a role for Mg2+ supplementation as a potential prebiotic to promote establishment of oral health-associated commensal streptococci.

Abstract
Objective: To study the protective effect and potential mechanism of heme oxygenase (HO-1)/carbon monoxide (CO)-mediated quercetin on alcoholic oxidative damage of primary rat hepatocytes. Methods: Primary rat hepatocytes were isolated and cultured by two-step collagenase technique. Ethanol exposed primary rat hepatocytes were simultaneously added with quercetin (100 μmol/L) and/or hemoglobin (100 μmol/L) or different doses of CO-releasing molecules (CORM-2, 5-50 μmol/L) for their combined action. After polling, LDH, AST activities and MDA and GSH levels were measured in the supernatant of cell culture. The alone or combined effects of quercetin, CORM-2, hemoglobin and zinc protoporphyrin IX exposed to ethanol were detected by the activity of CYP2E1 in liver microsomes. Statistical analysis of data was performed by analysis of variance (ANOVA) and intergroup comparison was done by SNK-test. Results: Simultaneous addition of 100 μmol/L quercetin had significantly reduced ethanol-induced AST and LDH release, and GSH consumption and MDA elevation extent. Moreover, quercetin had not only lost the hemoglobin (CO blocker) protective effect but also had further exacerbated ethanol-induced lipid peroxidation. CORM-2 had reduced ethanol-induced AST and LDH release, and GSH consumption and MDA production in liver cells, and thus had dose-dependent protective effect. Ethanol had increased significantly CYP2E1 activity. Quercetin or CORM-2 had inhibited CYP2E1 activity, while hemoglobin or protoporphyrin IX had eliminated quercetin inhibitory effect and had increased the CYP2E1 activity. Quercetin, and CYP2E1 activity was constant as compared to ethanol group when CORM-2, zinc protoporphyrin IX and ethanol were incubated with hepatocytes, but the CYP2E1 activity was significantly decreased (P < 0.05), and the differences were statistically significant. Conclusion: CO/HO-1 metabolite mediates the protective effect of quercetin on alcoholic oxidative damage of hepatocytes, which may be related to the inhibition of CYP2E1 activity.

Abstract
AIM To investigate the effect of radiomics in the assessment of alterations in canonical cancer pathways in breast cancer. MATERIALS AND METHODS Eighty-eight biopsy-proven breast cancer cases were included in the present study. Radiomics features were extracted from T1-weighted sagittal dynamic contrast-enhanced magnetic resonance imaging (MRI) images. Radiomics signatures were developed to predict genetic alterations in the cell cycle, Myc, PI3K, RTK/RAS, and p53 signalling pathways by using hypothesis testing combined with least absolute shrinkage and selection operator (LASSO) regression analysis. The predictive powers of the models were examined by the area under the curve (AUC) of the receiver operating characteristic curve. RESULTS A total of 5,234 radiomics features were obtained from MRI images based on the tumour region of interest. Hypothesis tests screened 250, 229, 156, 785, and 319 radiomics features that were differentially displayed between cell cycle, Myc, PI3K, RTK/RAS, and p53 alterations and no alteration status. According to the LASSO algorithm, 11, 12, 12, 15, and 13 features were identified for the construction of the radiomics signatures to predict cell cycle, Myc, PI3K, RTK/RAS, and p53 alterations, with AUC values of 0.933, 0.926, 0.956, 0.940, and 0.886, respectively. The cell cycle radiomics score correlated closely with the RTK/RAS and p53 radiomics scores. These signatures were also dysregulated in patients with different oestrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 statuses. CONCLUSION MRI-based radiogenomics analysis exhibits excellent performance in predicting genetic pathways alterations, thus providing a novel approach for non-invasively obtaining genetic-level molecular characteristics of tumours.

Abstract
In this study, Fe/Cu bimetal composite was prepared by high-energy ball milling (BM) method for the removal of refractory organics. The BM Fe/Cu bimetal was characterized by SEM-EDS, XRD, and XPS. Evenly distributed Fe and Cu was observed in the EDS mapping. In contrasting experiments, the removal rate of 4-chlorophenol (4-CP) by BM Fe/Cu materials was about 10-fold faster than that by chemical substitution deposition (CSD) of Fe/Cu material. Complete 4-CP removal and 66.7% of total organic carbon (TOC) mineralization in the BM Fe/Cu-O2 system were achieved. Dissolved oxygen plays a crucial role for 4-CP degradation through the in situ generation of reactive oxygen species (ROS) such as H2 O2 , ·OH, and · O 2 - via oxygen activation reactions. The predominant reactive radicals were identified to be · O 2 - and ·OH through ESR technique and inhibition experiments. The coexistence of oxidation and reduction of 4-CP in the BM Fe/Cu-O2 system was proposed. PRACTITIONER POINTS: 4-CP removal rate by BM Fe/Cu is 10-fold faster than that by CSD Fe/Cu at the same conditions. Complete 4-CP removal and 66.7% of TOC reduction were achieved. All three ROS including ·OH, · O 2 - , and H2 O2 coexisted in the BM Fe/Cu-O2 system. A harmonious coexistence of oxidation and reduction mechanism was proposed.

Abstract
A fast key parameter extraction algorithm is proposed to improve the real-time performance of temperature and strain measurements when performing Brillouin scattering-based fiber-distributed sensing. The algorithm uses a new initial value method that takes the extracted key parameters of the current point in the fiber as the initial guesses for the next point. Based on the old and new initial value method, the existing objective method, optimization algorithm, and convergence criterion, the key parameter extraction algorithms developed are implemented in Matlab using the typical Lorentzian, Gaussian, and pseudo-Voigt profiles. These algorithms are used to extract the parameters over a large range of measured Brillouin spectra for the entire fiber with different averaging times. The results reveal that apart from the case when the frequency sweep spans is less than the linewidth and the pseudo-Voigt profile is used (in this case, the mean computation time of the proposed algorithm is 1.1% larger than that of the referenced algorithm), the proposed algorithm not only ensures high accuracy in extracting the key parameters, but also improves the arithmetic efficiency by 16.3%-49.1%.

Abstract
Background Accumulating evidence suggests that the AKT/mTOR pathway plays an important role in the pathogenesis of systemic lupus erythematosus (SLE) through activating T cells, and there are few studies looking into the role of microRNA (miRNAs) in the mechanism. We first found that miR-633 expression in CD4+T cells of SLE patients was significantly reduced. Objective To investigate the role of miR-633 in the AKT/mTOR pathway in lupus CD4+T cells. Methods Samples of 17 SLE cases and 16 healthy controls were collected to detect the expression of miR-633, AKT1, mTOR mRNA and proteins by quantitative polymerase chain reaction (qPCR) and Western-blot, respectively. To determine whether AKT1 is a direct target of miR-633, a luciferase assay was performed. In vitro, AKT1 siRNA, miR-633 mimics/inhibitors or negative controls were transfected to Jurkat cells, human primary CD4+T cells and lupus CD4+T cells. RNA and proteins were extracted after 48 h, and levels of AKT/mTOR pathway markers and downstream multiple cytokines were detected by qPCR or Western-blot. Results In SLE patients, the miR-633 levels in CD4+T cells were significantly decreased and negatively correlated with SLEDAI. AKT1, mTOR mRNA and proteins were all up-regulated. The degree of downregulation of miR-633 was correlated negatively with AKT1 mRNA. The luciferase assay proved that AKT1 is a direct target of miR-633. In Jurkat and lupus CD4+T cells, overexpression of miR-633 could result in lower levels of AKT1 and mTOR. Inhibition of miR-633 expression in primary CD4+T cells caused reverse effects, and protein levels of p-AKT, p-mTOR, and p-S6RP increased. Moreover, among various cytokines, the expression of IL-4, IL-17, and IFN-γ mRNA was raised. Conclusion Our study suggests that miR-633 deletion can activate the AKT/mTOR pathway by targeting AKT1 to participate in the pathogenesis of SLE.

Abstract
Objective: To investigate frailty progress status and related factors in the elderly living in communities. Methods: A cohort of elderly people aged 65 and over in Pingyi community of Dujiangyan, Sichuan province, was established. Face-to-face questionnaire survey was conducted by trained interviewers. The frailty status, cognitive function, nutrition status and other functions of the subjects surveyed were evaluated at baseline survey and during follow-up. The socio-demographic and clinical characteristics of the subjects surveyed were assessed at baseline survey. Binary logistic regressions were used to identify factors associated with frailty progress. Results: A total of 653 elderly people were surveyed in January 2014, and 507 elderly people were followed up while 146 elderly people terminated further follow-up in January 2017. The prevalence rates of frailty and pre-frailty at baseline survey were 11.2% (n=57) and 26.2% (n=133), respectively. After 3 years, 205 subjects (40.4%) surveyed experienced frailty progress, 276 (54.5%) remained to be in frailty state at baseline survey, and 26 (5.1%) had improvement. Disability (OR=8.27, 95%CI: 1.62-42.26), visual problem (OR=2.02, 95%CI: 1.27-3.22), cognitive impairment (OR=1.94, 95%CI: 1.08-3.48), poor self-rated health (OR=1.89, 95%CI: 1.07-3.31), chronic pain (OR=1.57, 95%CI: 1.03-2.40) and older age (OR=1.12, 95%CI: 1.08-1.17) were independently associated with the progress of frailty. In contract, overweight was a protective factor (OR=0.54, 95%CI: 0.34-0.85). Conclusions: Frailty is a dynamic syndrome affected by several socio-demographic factors and geriatric factors. The results of the study can be used in the prevention of frailty progress in the elderly in communities.
