RESUMO
In this work, genetic algorithm (GA) is employed to optimize convolutional neural networks (CNNs) for predicting the confinement loss (CL) in anti-resonant fibers (ARFs), achieving a prediction accuracy of CL magnitude reached 90.6%, which, to the best of our knowledge, represents the highest accuracy to date and marks the first instance of using a single model to predict CL across diverse ARF structures. Different from the previous definition of ARF structures with parameter groups, we use anchor points to describe these structures, thus eliminating the differences in expression among them. This improvement allows the model to gain insight into the specific structural characteristics, thereby enhancing its generalization capabilities. Furthermore, we demonstrate a particle swarm optimization algorithm (PSO), driven by our model, for the design of ARFs, validating the model's robust predictive accuracy and versatility. Compared with the calculation of CL by finite element method (FEM), this model significantly reduces the cost time, and provides a speed-up method in fiber design driven by numerical calculation.
RESUMO
INTRODUCTION: Irritability, a common neuropsychiatric symptom in Huntington's disease (HD), lacks a standardized measurement. The Irritability Scale (IS), tailored for HD, has patient and informant versions, but variable interrater agreement has been reported frequently in previous studies. To enhance the clinical utility of the IS, this study aimed to identify the most reliable components estimating the underlying construct and develop a shortened version for time-limited contexts. METHODS: Participant and informant/observer concordance and the relationship of individual items to the complete IS scale were assessed. The short-form (SF) items were selected based on interrater agreement, exploratory factor analysis (EFA), and Item Response Theory (IRT) analysis results. Pair-wise correlation and covariance models were used to examine how SF predicted total IS score in 106 participants from the STAIR (Safety, Tolerability, and Activity of SRX246 in Irritable Subjects with Huntington's Disease) trial. Item Response Theory (IRT) analysis was used to evaluate the range and function of the selected items. RESULTS: IS interrater agreement was statistically significant (r = 0.33, p = .001). In combination with EFA factors and IRT analyses, five items were identified that showed good reliability and performance in differentiating levels of irritability. CONCLUSION: The proposed 5-item SF IS provided a reliable measure of the full scale and may be less burdensome for use in a clinical setting.

Lung adenocarcinoma (LUAD) remains one of the most aggressive tumors and the efficacy of conventional treatment has been bleak. Nowadays, gene-targeted therapy has become a new favorite in tumor therapy. Herein, we investigated the effect of platelet derived growth factor BB (PDGFBB) on LUAD. Firstly, PDGFBB was upregulated in LUAD patients and closely linked with poor survival. Furthermore, the expression of PDGFBB and PDGFRα/ß in LUAD cells was higher than that in normal lung cells. By loss-of-function with herpes simplex virus (HSV)-PDGFi-shRNA, we found that PDGFBB knockdown caused a significant decrease in proliferation and migration, but evoked apoptosis of LUAD cells in vitro. Conversely, exogenous PDGFBB held adverse effect. Additionally, A549 cells with PDGFBB knockdown had a low probability of tumorigenesis in vivo. Moreover, PDGFBB knockdown restrained the growth of xenografts derived from normal A549 cells. Mechanistically, PDGFBB knockdown suppressed PI3K/AKT and Ras/MAPK signaling, while PDGFBB was the opposite. Therefore, we concluded that PDGFBB might facilitate the tumorigenesis and malignancy of LUAD through its functional downstream nodes-PI3K/AKT and Ras/MAPK signaling, which supported that PDGFBB could serve as a rational therapeutic target for LUAD.

Electroplating sludge (ES) is a globally prevalent hazardous waste that primarily contains Cr, Cu, Ni, and Fe. However, the residual Cr phases within the slag potentially poses an environmental risk in current vitrification. A novel method for effective recovering and solidifying Cr in ES is proposed in this work. ES was desulfurized and subsequently co-treated with ferrosilicon (Fe-Si) and spent carbon anode (SCA) for enhancing the recovery of Cr, Cu, Ni, and Fe to prepare crude stainless steel. Under optimal conditions, the recovery ratios of Cr, Cu, Ni, and Fe reached 96.96%, 99.45%, 99.92%, and 99.20%, respectively, signifying improvements of 21.4%, 0.2%, 1.5%, and 2.8%, respectively, compared with existing research. Meanwhile, the fluoride in SCA yielded CaF2, further progressing to the Si-Ca-F-Na-Al-O phase, with a solidification ratio of 97.87%. The Cr leaching content of the residual Cr-Cu-S phase in the slag remained below 5 mg/L across a pH range of 2-4, demonstrating enhanced stability compared to prior alloy, oxide, and chemically dissolved phases. An innovative approach for solidify Cr by forming matte holds implications for the treatment of Cr-containing solid wastes such as chromium slag, tannery sludge and stainless steel slag.
RESUMO
BACKGROUND: Respiratory syncytial virus (RSV) is the leading global cause of respiratory infections and is responsible for about 3 million hospitalizations and more than 100,000 deaths annually in children younger than 5 years, representing a major global healthcare burden. There is a great unmet need for new agents and universal strategies to prevent RSV infections in early life. A multidisciplinary consensus development group comprising experts in epidemiology, infectious diseases, respiratory medicine, and methodology aims to develop the current consensus to address clinical issues of RSV infections in children. DATA SOURCES: The evidence searches and reviews were conducted using electronic databases, including PubMed, Embase, Web of Science, and the Cochrane Library, using variations in terms for "respiratory syncytial virus", "RSV", "lower respiratory tract infection", "bronchiolitis", "acute", "viral pneumonia", "neonatal", "infant" "children", and "pediatric". RESULTS: Evidence-based recommendations regarding diagnosis, treatment, and prevention were proposed with a high degree of consensus. Although supportive care remains the cornerstone for the management of RSV infections, new monoclonal antibodies, vaccines, drug therapies, and viral surveillance techniques are being rolled out. CONCLUSIONS: This consensus, based on international and national scientific evidence, reinforces the current recommendations and integrates the recent advances for optimal care and prevention of RSV infections. Further improvements in the management of RSV infections will require generating the highest quality of evidence through rigorously designed studies that possess little bias and sufficient capacity to identify clinically meaningful end points.

The analysis of ammonia nitrogen in real water samples is challenging due to matrix interferences and difficulties for rapid on-site analysis.On the basis of the standard method,i.e.water quality-determination of ammonia nitrogen-salicylic acid spectrophotometry(HJ 536-2009),a simple device for online detecting ammonia nitrogen was developed using a sequential injection analysis(SIA)system in this work.The ammonia nitrogen transformation system,color reaction system,and detection system were built in compatible with the SIA system,respectively.In particular,the detection system was assembled by employing light-emitting diode as the light source,photodiode as the detector,and polyvinylchloride tube as the cuvette,thus significantly reducing the volume,energy consumption and fabricating cost of the detection system.As a result,the accurate analysis of ammonia nitrogen in complex water samples was achieved.A quantitative detection of ammonia nitrogen in water sample was obtained in 12 min,along with linear range extending to 1000 μmol/L,precisions(Relative standard deviation,RSD)of 4.3%(C=10 μmol/L,n=7)and 4.2%(C=500 μmol/L,n=7),and limit of detection(LOD)of 0.65 μmol/L(S/N=3,n=7).The results of interfering experiments showed that the detection of ammonia nitrogen by the developed device was not interfered by the common coexisting ions and components,therefore the environmental water could be directly analyzed,such as reservoir water,domestic sewage,sea water and leachate of waste landfill.The analytical results were consistent with those obtained by the environmental protection standard method(Water quality determination of ammonia nitrogen-salicylic acid spectrophotometry,HJ 536-2009).In addition,the spiking recoveries were in the range of 92.3%-98.1%,further confirming the accuracy and practicality of the developed device.

RESUMO
BACKGROUND:As a common clinical digestive disorder,irritable bowel syndrome becomes an advantageous disease of acupuncture treatment.However,the therapeutic mechanisms remain unclear.The methodological characteristics of omics coincide with the multi-target and multi-level characteristics of acupuncture,providing the possibility of revealing the principle of acupuncture in the treatment of the disease. OBJECTIVE:To investigate the pathogenesis of irritable bowel syndrome with diarrhea(IBS-D)and the effect of acupuncture at the combined points(selected based on etiologies and symptoms)on IBS-D based on proteomics. METHODS:Twelve 3-month-old male Sprague-Dawley rats were randomly divided into three groups:a control group,an IBS-D model group and an acupuncture group.The IBS-D rat models were prepared using the CAS method.After successful modeling,bilateral Zusanli points,bilateral Neiguan points and Guanyuan points were selected for acupuncture treatment in the acupuncture group,with a frequency of 120 times/minute,1 minute of acupuncture every 4 minutes,and 15 minutes of needle retention,at an interval of 1 day every 6 days,for 28 days in total.Rats in the normal control group and the model group were not given any intervention.The pressure threshold of rat abdominal retraction reflex was measured to evaluate the visceral hypersensitivity of rats.Proteomics analysis was performed using the liquid chromatography-tandem mass spectrometry-based platform.MaxQuant software,Perseus software and DAVID,KOBAS,VENNY,STRING online tools were used for the bioinformatics analysis of proteomic data.Visualization analysis was done using Cytoscape 3.7.1 software. RESULTS AND CONCLUSION:There were 47 differentially expressed proteins between the IBS-D model and control groups.Function analysis of differentially expressed proteins revealed that the pathogenic mechanism of IBS-D was associated with abnormal energy metabolism,the imbalance of colon motor function and increased visceral sensitivity.Important proteins related to IBS-D pathogenesis included Atp5a1,Atp5c1,Idh3b,Atp2a3,Pdhb,Ppp1ca and Mapk3.Sixty-one differentially expressed proteins were identified between the acupuncture group and IBS-D model group.Acupuncture at the combined points reversed the up-regulation of nine differentially expressed proteins and the down-regulation of nine differentially expressed proteins.Bioinformatics analysis revealed that acupuncture at the combined points for IBS-D could function via multi-targets and multi-pathways,reverse the damage of energy metabolism caused by IBS-D,and play a role against oxidative stress and inflammation,thereby relieving pain and regulating the imbalance of intestinal function.Important proteins related to acupuncture effects included Atp5a1,Atp5c1,Pdhb,Sars,Uqcrc2,Prdx2,Prdx4,Ppp1ca,Manf and Tmsb4x3.All these findings preliminarily illustrate the potential molecular mechanisms of IBS-D and the effect of acupuncture at the combined points in the treatment of IBS-D at the protein level,which provide a basis for the clinical application of acupuncture at the combined points.
RESUMO
Objective To analyze the influencing factors for catheter-associated infection(CAI)in chemotherapy treated patients after indwelling peripherally inserted central catheter(PICC)based on a random forest model.Methods 400 tumor patients who received chemotherapy and PICC were selected and divided into the training set(n=300)and the test set(n=100)in a 3∶1 ratio through computer-generated random number.Patients in the training set were subdivided into the non-infection group and the infection group based on the occurrence of infec-tion.Clinical data from two groups of patients were compared.Influencing factors for the occurrence of CAI after PICC were analyzed with multivariate logistic regression model and the integrated classification algorithm of random forest model,and the predictive performance of the two methods was compared.Results Among 300 chemotherapy treated patients in the training set,32 cases(10.67%)experienced CAI.Compared with the non-infection group,patients in the infection group had more single punctures for catheterization,longer PICC retention time,larger pro-portion of catheter movement,larger proportion of complication with diabetes,higher frequency of dressing chan-ges,lower white blood cell count and immune function(all P<0.05).PICC retention time,catheter movement,complication with diabetes,dressing change frequency,white blood cell(WBC)and immune function were inde-pendent influencing factors for CAI after PICC(all P<0.05).The random forest model showed that ranking by the importance of different influencing factors was as following:PICC retention time,catheter movement,complication with diabetes,WBC,dressing change frequency and immune function.The integrated classification algorithm of random forest model for predicting the occurrence of CAI in chemotherapy treated patients showed that the area un-der the receiver operating characteristic(ROC)curve(AUC)was 0.872,which had better prediction performance compared with the logistic regression model(AUC=0.791).Conclusion PICC retention time,catheter movement,complicated with diabetes,dressing change frequency,WBC level and immune function are independent influencing factors for CAI in chemotherapy treated patients.The integrated classification algorithm of random forest model can be used to predict CAI in chemotherapy treated patients,and its prediction performance is better than that of the logistic regression model.

The relevant targets of breast cancer with the syndrome of Zheng-deficiency, toxic-incandescence were obtained using OMIM, GeneGards and Drugbank databases, and the relevant targets of HQJD for the treatment of breast cancer with the syndrome of Zheng-deficiency and toxic incandescence were obtained by intersection; The Cytoscape 3.9.1 software was used to build the protein protein interaction (PPI) network and the " drug active component target disease" network on the basis of String 11.0 database, and the core active components and core targets of HQJD in treating breast cancer with the syndrome of Zheng-deficiency and toxic-incandescence were inferred according to the topological parameters. gene ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were performed on core targets using R language; and molecular docking verification on the main active ingredients and core targets were conducted.Results:230 effective targets of active ingredients of HQJD were screened, and 15 467 active ingredients of breast cancer with syndrome of Zheng-deficiency/toxic-incandescence were obtained; 217 intersection targets; GO function enrichment analysis showed that the treatment of HQJD for breast cancer with the syndrome of Zheng-deficiency and toxic-incandescence mainly involved oxidative stress and cytochemical stress; The enrichment analysis of KEGG pathway showed that HQJD treatment of breast cancer with the syndrome of Zheng-deficiency and toxic-incandescence was mainly related to phosphatidylinositol 3-protein kinase B (PI3K-Akt), interleukin-17 (IL-17) and other signal pathways. The molecular docking results showed that the main active ingredients such as β-sitosterol, stigmasterol, luteolin had good binding ability with core targets.Conclusions:HQJD has the characteristics of multi-component, multi target and multi pathway in the treatment of breast cancer with syndrome of Zheng-deficiency and toxic-incandescence, and its main mechanism may be related to PI3K-Akt, IL-17, P53 and other signal pathways.
RESUMO
Macroautophagy (referred to as autophagy hereafter) is a major intracellular lysosomal degradation pathway that is responsible for the degradation of misfolded/damaged proteins and organelles. Previous studies showed that autophagy protects against acetaminophen (APAP)-induced injury (AILI) via selective removal of damaged mitochondria and APAP protein adducts. The lysosome is a critical organelle sitting at the end stage of autophagy for autophagic degradation via fusion with autophagosomes. In the present study, we showed that transcription factor EB (TFEB), a master transcription factor for lysosomal biogenesis, was impaired by APAP resulting in decreased lysosomal biogenesis in mouse livers. Genetic loss-of and gain-of function of hepatic TFEB exacerbated or protected against AILI, respectively. Mechanistically, overexpression of TFEB increased clearance of APAP protein adducts and mitochondria biogenesis as well as SQSTM1/p62-dependent non-canonical nuclear factor erythroid 2-related factor 2 (NRF2) activation to protect against AILI. We also performed an unbiased cell-based imaging high-throughput chemical screening on TFEB and identified a group of TFEB agonists. Among these agonists, salinomycin, an anticoccidial and antibacterial agent, activated TFEB and protected against AILI in mice. In conclusion, genetic and pharmacological activating TFEB may be a promising approach for protecting against AILI.
RESUMO
Objective To explore the value of blood inflammatory load in predicting overall survival of elderly patients with epithelial ovarian cancer (EOC). Methods Elderly patients with EOC were selected, and their clinical data and peripheral blood parameters were collected. We constructed an inflammation-related blood scoring system using univariate and multivariate Cox regression analysis. The Kaplan-Meier method was used for survival analysis. We used Cox proportional hazards analysis to identify the independent prognostic factors. A nomogram model was constructed based on independent prognostic factors, and the receiver operating characteristic curve, C-index, and calibration curve were used to evaluate the model. Results Patients with high blood inflammatory load had worse prognosis (P=0.002). Compared with the low inflammatory load group, patients with high inflammatory load had later clinical stages and larger ascites volume (P<0.05). Cox regression analysis showed that ACCI, CA125, residual lesions, and blood score were independent factors affecting overall survival (P<0.05). Conclusion The blood inflammatory load is the biomarker for the prognosis of elderly patients with EOC. Scoring the inflammatory load in the blood can assist in efficacy monitoring and treatment intervention of ovarian cancer patients.

RESUMO
AIM: To evaluate the efficacy and safety of interventional therapy combined with tumor drug injection under bronchoscope for central non-small cell lung cancer (NSCLC). METHODS: Sixty-four patients who met the test admission criteria were randomly assigned to the experimental group and the control group according to the ratio of 1:1, and were given bronchoscopic interventional therapy combined with local drug injection of recombinant human endostatin combined with platinum-containing dual-drug chemotherapy and platinum-containing dual-drug alone, respectively. The curative efficiency and safety of the two groups were compared. RESULTS: Compared with the control group, the KPS score, dyspnea grading were significantly improved (P<0.05). The effective rate of the test group was 78.12%, which was higher than 37.5% in the control group, the difference between the two groups was significant (P<0.05). Moreover, there was also a significant difference in the 1-year survival rate between the experimental group and the control group (P<0.05). CONCLUSION: The treatment of central NSCLC by interventional therapy combined with tumor drug injection through fiberoptic bronchoscope has obvious clinical efficacy, which can effectively alleviate the clinical symptoms and improve the quality of life of patients. There is no significant difference in adverse reactions between the two groups, and is worthy of popularization and application.
RESUMO
Objective@#: Blood-blister aneurysms (BBAs) of the internal carotid artery (ICA) are challenging lesions with high morbidity and mortality rates. Although research on BBAs is well documented in different populations, the study of BBAs in the Tibetan population is extremely rare. This study aimed to evaluate the characteristics of BBAs and analyze the treatment modalities and long-term outcomes in the Tibetan population in comparison with the Han population. @*Methods@#: The characteristics of patients with BBAs of the ICA from January 2009 to January 2021 at our institution were reviewed. The features of aneurysms, treatment modalities, complications, and follow-up outcomes were retrospectively analyzed. @*Results@#: A total of 130 patients (41 Tibetan and 89 Han patients) with BBAs of the ICA who underwent treatment were enrolled. Compared with the Han group, the Tibetan group significantly demonstrated a high ratio of BBAs among ICAs (8.6%, 41/477 vs. 1.6%, 89/5563; p<0.05), a high ratio of vasospasm (34.1%, 14/41 vs. 6.7%, 6/89; p=0.001), a high risk of ischemic events (43.9%, 18/41 vs. 22.5%, 20/89; p<0.05), and a low ratio of good outcomes (modified Rankin scale, 0–2) at the 1-year follow-up (51.2%, 21/41 vs. 74.2%, 66/89; p<0.05). The multivariate regression model showed that ischemic events significantly contributed to the prediction of outcomes at 1 year. Further analysis revealed that microsurgery and vasospasm were associated with ischemic events. @*Conclusion@#: In comparison with Han patients, the Tibetan population had a high ratio of BBA occurrence, a high incidence of ischemic events, and a high ratio of poor outcomes. The endovascular approach showed more benefits in BBA patients.
RESUMO
Objective To understand the discharge readiness of fathers of preterm infants in the Neonatal Intensive Care Unit(NICU),analyze its influencing factors,and provide a basis for formulating individualized discharge health education plans and continuous care plans.Methods A convenience sampling method was employed to select fathers of preterm infants admitted to the NICU in a tertiary A hospital in Zhejiang Province from March 2022 to June 2022 as the subjects of the study.A general information questionnaire and the Discharge Readiness-Parent Version scale were used for the survey.Multiple linear regression analysis was applied to analyze the factors influencing the discharge readiness of fathers of NICU preterm infants.Results A total of 186 fathers of NICU preterm infants were included in the study.The total score of the Discharge Readiness-Parent Version scale was(179.97±28.20)points;the standardized score was(7.82±1.16)points;33.3%of the fathers of preterm infants had a standardized score of<7 points.Multiple linear regression analysis results showed that the factors influencing the discharge readiness of fathers of NICU preterm infants included the gestational age at birth,birth weight,length of hospital stay,distance to access healthcare service,as well as the fathers'age,annual family income,and number of children in the family.Conclusion The discharge readiness of fathers of NICU preterm infants is at a moderate level.Nursing staff need to pay attention to the discharge readiness of fathers of preterm infants who have lower gestational age at birth,lower birth weight,longer hospital stays,longer distance to healthcare service,and who are younger,have lower annual family income,and are having their first child.Individualized discharge health education plans and continuous care plans should be formulated for them to improve their caregiving knowledge and skills.
