Brief Analysis on the Earlier the Better in SL Learning

With the intense globalization and human migration,a worldwide attention to multiple languages,cultures and abilities to communicate effectively with people across languages and cultures has been aroused. Under such circumstance,the switch to an earlier start of second language introducing in school appears to be an international phenomenon. This paper just aims to make a discussion on the idea of the earlier the better in SL learning.

Analysis of the causative factors related to earlier emulsification of silicone oil

The aim of this study is to report and analyze the factors related with earlier occurrence of silicone oil(SO) emulsification in patients underwent pars plana vitrectomy and SO injection in our hospital. We retrospectively reviewed consecutive case series undergone both SO injection and removal in our hospital, and 182 ones were eligible. Possible related independent factors included: macula status(on/off), concomitant phacoemulsification with the surgery of SO tamponading, concomitant status of proliferative vitreoretinopathy, combined surgery of retinotomy, time to have emulsification(<6 mo/≥6 mo after primary SO injection), route of SO injection(anterior/posterior), lens status(aphakic/pseudophakic/phakic), anesthesia(local/general), brands and type of SO, with/without episcleral cryotherapy, with/without hypertension, with/without diabetes, with/without intraoperative use of triamcinolone acetonide. The study revealed that brand and type of SO was the significant factor related with earlier emulsification of SO. Further study was warranted to find out the underlying causes.

The First Discovery of the Earliest Devonian Conodont Zonal Fossil from the "Gavuu Member" in Mushgai Area of South Gobi,Mongolia

Conodont Caudicriodus woschimidti woschmidti has been found from a big outcrop (hill) of the Bayan-Kho-shuu Ruins Section which was previously assigned to the Silurian Gavuu Member of the Mandalovoo Formation. This is first time to find the lowermost Devonian conodont zonal fossil in Mongolia. The lower part of the Gavuu Member is Sil-urian. But the strata from where we collected samples M-9～M-12 definitely belong to Lower Devonian (lower Lochko-vian) rather than Lower Silurian. The Mandalovoo Formation should be named Mandalovoo Group, and its three mem-bers should be changed into three formations.

The earliest evidence for a microblade adaptation in the remote,high altitude regions of the Tibetan Plateau

Microblade assemblages are among the most common prehistoric archaeological materials found on the Tibetan Plateau(TP)and are thought to indicate large scale migration to and settlement of the TP.Few microblade sites,however,have been systematically excavated,especially in the remotest,highest-elevation regions of the TP.The timing of the large-scale arrival,spread,and permanent settlement of people on the TP therefore remains controversial.In this paper,we report on a recently excavated site,Locality 3 of the Nwya Devu Site(ND3),located at 4600 meters above sea level(masl),near the shore of Ngoin Lake,on the interior TP.Our analyses reveal a fairly typical microblade technological orientation and two types of microblade cores:wedge-shaped and semi-conical,which are similar to those found throughout North China.Using Optically Stimulated Luminescence(OSL)dating and AMS^(14)C dating,the age of ND3 ranges from 11 to 10 ka.This date range indicates ND3 is the oldest microblade site yet recorded in the remote,high-elevation regions of the TP and thus provides important information about when and how hunter-gatherers using microblades began exploiting the higher altitudes of the TP.Taken together,studies at ND3 and throughout the TP suggest that a microblade adaptation is associated with the first prolonged human occupation of the plateau and that microblades played a significant role in mediating the risks and facilitating the mobility necessary to permanently inhabit the TP.

Is Earlier Really Better?——A Report of a Study Investigating the Effects of Earlier English Education in China

Although age has been considered to be a major factor determines success in learning asecond or foreign language by many scholars, we are unclear whether it is the learning contextor the biological capacity to learn that matters most. This study attempts to gain new insightsby investigating the effects of early English learning in China, a language learning contextoften marked by a lack of sufficient input in English. About 800 participants from twoschools in two geographic locations (Beijing and Tunxi) completed a survey, and took botha pre-test (September 2003) and a post-test (April 2004) with instruments developedspecifically for the study. The results obtained by a series of skill-specific, grade-specific,and school-specific two-way and three-way ANOVAs, and post-hoc contrasts indicate thatearly starters in Beijing outperformed late starters while there was hardly any advantage ofearly learning of English among school students in Anhui. This suggests that differences inteaching quality, and overall English environment, as well as possible the English exposureoutside urban and rural schools play a more significant role in learner success.

First Discovery of the Earliest Angiospermous Megafossils in the World

The first discovery of the earliest angiospermous megafossils, so far in the world,was made by the authors from the Lower Cretaceous Chengzihe Formation of Jixi Basin, eastern Heilongjiang Province,China.Among the angiospermous fossils there are 5 species belonging to 5 genera (including 4 gen.et sp.nov.) reported in this paper.Their microphyllous leaves with irregular venations show the characteristics of some primitive angiosperms whose age is mostly corresponding to the late Hauterivian-early Barremian, partly proved by the underlying conformably marine beds with the Valanginian-Hauterivian dinoflagellates revealed newly also by the authors.

Early identification of stroke through deep learning with multi-modal human speech and movement data

Early identification and treatment of stroke can greatly improve patient outcomes and quality of life.Although clinical tests such as the Cincinnati Pre-hospital Stroke Scale(CPSS)and the Face Arm Speech Test(FAST)are commonly used for stroke screening,accurate administration is dependent on specialized training.In this study,we proposed a novel multimodal deep learning approach,based on the FAST,for assessing suspected stroke patients exhibiting symptoms such as limb weakness,facial paresis,and speech disorders in acute settings.We collected a dataset comprising videos and audio recordings of emergency room patients performing designated limb movements,facial expressions,and speech tests based on the FAST.We compared the constructed deep learning model,which was designed to process multi-modal datasets,with six prior models that achieved good action classification performance,including the I3D,SlowFast,X3D,TPN,TimeSformer,and MViT.We found that the findings of our deep learning model had a higher clinical value compared with the other approaches.Moreover,the multi-modal model outperformed its single-module variants,highlighting the benefit of utilizing multiple types of patient data,such as action videos and speech audio.These results indicate that a multi-modal deep learning model combined with the FAST could greatly improve the accuracy and sensitivity of early stroke identification of stroke,thus providing a practical and powerful tool for assessing stroke patients in an emergency clinical setting.

Therapeutic potential of stem cells in subarachnoid hemorrhage

Aneurysm rupture can result in subarachnoid hemorrhage,a condition with potentially severe consequences,such as disability and death.In the acute stage,early brain injury manifests as intracranial pressure elevation,global cerebral ischemia,acute hydrocephalus,and direct blood–brain contact due to aneurysm rupture.This may subsequently cause delayed cerebral infarction,often with cerebral vasospasm,significantly affecting patient outcomes.Chronic complications such as brain volume loss and chronic hydrocephalus can further impact outcomes.Investigating the mechanisms of subarachnoid hemorrhage-induced brain injury is paramount for identifying effective treatments.Stem cell therapy,with its multipotent differentiation capacity and anti-inflammatory effects,has emerged as a promising approach for treating previously deemed incurable conditions.This review focuses on the potential application of stem cells in subarachnoid hemorrhage pathology and explores their role in neurogenesis and as a therapeutic intervention in preclinical and clinical subarachnoid hemorrhage studies.

Gastric polyps are not created equal: Know your enemy

Gastric polyps are commonly detected during upper gastrointestinal endoscopy.They are most often benign and rarely become malignant.Nevertheless,adequate knowledge,diagnostic modalities,and management strategies should be the endoscopist’s readily available“weapons”to defeat the potentially malignant“enemies”.This article sheds light on the valuable effort by Costa et al to generate a new classification system of gastric polyps as“good”,“bad”,and“ugly”.This comprehensive overview provides clinicians with a simplified decision-making process.

Intricacies during pregnancy with gestational diabetes mellitus

The study by Cao et al aimed to identify early second-trimester biomarkers that could predict gestational diabetes mellitus(GDM)development using advanced proteomic techniques,such as Isobaric tags for relative and absolute quantitation isobaric tags for relative and absolute quantitation and liquid chromatography-mass spectrometry liquid chromatography-mass spectrometry.Their analysis revealed 47 differentially expressed proteins in the GDM group,with retinol-binding protein 4 and angiopoietin-like 8 showing significantly elevated serum levels compared to controls.Although these findings are promising,the study is limited by its small sample size(n=4 per group)and lacks essential details on the reproducibility and reliability of the protein quantification methods used.Furthermore,the absence of experimental validation weakens the interpretation of the protein-protein interaction network identified through bioinformatics analysis.The study's focus on second-trimester biomarkers raises concerns about whether this is a sufficiently early period to implement preventive interventions for GDM.Predicting GDM risk during the first trimester or pre-conceptional period may offer more clinical relevance.Despite its limitations,the study presents valuable insights into potential GDM biomarkers,but larger,well-validated studies are needed to establish their predictive utility and generalizability.

Insights on Peripheral Blood Biomarkers for Parkinson’s Disease

Parkinson’s disease(PD)is a common neurodegenerative disorder with profound impact on patients’quality of life and long-term health,and early detection and intervention are particularly critical.In recent years,the search for precise and reliable biomarkers has become one of the key strategies to effectively address the clinical challenges of PD.In this paper,we systematically evaluated potential biomarkers,including proteins,metabolites,epigenetic markers,and exosomes,in the peripheral blood of PD patients.Protein markers are one of the main directions of biomarker research in PD.In particular,α‑synuclein and its phosphorylated form play a key role in the pathological process of PD.It has been shown that aggregation ofα-synuclein may be associated with pathologic protein deposition in PD and may be a potential marker for early diagnosis of PD.In terms of metabolites,uric acid,as a metabolite,plays an important role in oxidative stress and neuroprotection in PD.It has been found that changes in uric acid levels may be associated with the onset and progression of PD,showing its potential as an early diagnostic marker.Epigenetic markers,such as DNA methylation modifications and miRNAs,have also attracted much attention in Parkinson’s disease research.Changes in these markers may affect the expression of PD-related genes and have an important impact on the onset and progression of the disease,providing new research perspectives for the early diagnosis of PD.In addition,exosomes,as a potential biomarker carrier for PD,are able to carry a variety of biomolecules involved in intercellular communication and pathological regulation.Studies have shown that exosomes may play an important role in the pathogenesis of PD,and their detection in blood may provide a new breakthrough for early diagnosis.It has been shown that exosomes may play an important role in the pathogenesis of PD,and their detection in blood may provide new breakthroughs in early diagnosis.In summary,through in-depth evaluation of biomarkers in the peripheral blood of PD patients,this paper demonstrates the important potential of these markers in the early diagnosis of PD and in the study of pathological mechanisms.Future studies will continue to explore the clinical application value of these biomarkers to promote the early detection of PD and individualized treatment strategies.

Systematic comparison of Kawasaki disease Z-score formulas:Enhancing diagnostic accuracy and clinical applicability across populations

This study aims to evaluate the performance of six distinct Z-score formulas in diagnosing coronary artery dilation in Kawasaki disease(KD)patients,with a focus on their clinical applicability across diverse populations.A retrospective analysis was conducted using comparative statistical methods to assess the sensitivity and specificity of each formula.The Kobayashi and Dallaire formulas demonstrated the highest sensitivity in China,particularly in younger patients with prolonged fever duration.Our findings provide evidence-based recommend-ations for selecting Z-score formulas to optimize diagnostic precision in KD patients.

Comparative study of living donor kidney transplants:Right vs left

BACKGROUND Transplant teams often hesitate to use the right kidney(RK)in living donor(LD)transplants due to the complexities of anastomosing the short,thin-walled right renal veins,which can potentially lead to graft loss or graft dysfunction.Nevertheless,circumstances may arise where selecting the RK over the left kidney(LK)is unavoidable.Consequently,it is crucial to thoroughly examine the implications of such a choice on the overall transplant outcome.AIM To compare transplant outcomes between recipients of RK and LK while examining the factors that influence these outcomes.METHODS We retrospectively analyzed data from adult patients who received LD kidney transplants involving meticulous patient selection and surgical techniques at our center from January 2020 to December 2023.We included all kidney donors who were over 18,fit to donate,and had undergone diethylenetriamine pentaacetic acid split function and/or computed tomography based volumetry.The variables examined comprised donor and recipient demographics,and outcome measures included technical graft loss(TGL),delayed or slow graft function(SGF),and post-transplant serum creatinine(SC)trends.We used a logistic regression model to assess the likelihood of adverse outcomes considering the donor kidney side.RESULTS Of the 250 transplants performed during the period,56(22%)were RKs.The recipient demographics and transplant factors were comparable for the right and LKs,except that the donor warm and cold ischemia time were shorter for RKs.TGL and SGF each occurred in 2%(n=1)of RKs and 0.5%(n=1)of LKs,the difference being insignificant.These complications,however,were not related to the venous anastomosis.One RK(2%)developed delayed graft function after 48 hours,which was attributable to postoperative hypoxia rather than the surgical technique.The post-transplant SC trend and mean SC at the last follow-up were similar across both kidney sides.CONCLUSION The donor kidney side has little impact on post-transplant adverse events and graft function in LD transplants,provided that careful patient selection and precise surgical techniques are employed.

Effects of glycemic indicators on early neurological outcomes in patients with acute ischemic stroke treated with intravenous thrombolysis

BACKGROUND Stress hyperglycemia(SH)is a common phenomenon that is present in about 50%of patients with acute ischemic stroke(AIS).It is thought to be a main risk factor for poor functional outcome among patients with AIS undergoing intravenous thrombolysis(IVT).AIM To investigate the predictive value of glycemic indicators for early neurological outcomes(ENOs)in patients with AIS treated with IVT.METHODS We retrospectively reviewed a prospectively collected database of patients with AIS who underwent IVT at the Department of Neurology,Second Affiliated Hospital of Xuzhou Medical University,between January 2017 and June 2022.ENO included early neurological improvement(ENI)and early neurological deterioration(END),defined as a decrease or increase in the National Institutes of Health Stroke Scale(NIHSS)score between baseline and 24 hours after IVT.We analyzed the associations between glycemic indicators[including admission hyperglycemia(AH),fasting blood glucose(FBG),and SH ratio(SHR)]and ENO in all patients and in subgroups stratified by diabetes mellitus(DM).RESULTS A total of 819 patients with AIS treated with IVT were included.Among these,AH was observed in 329 patients(40.2%).Compared with patients without AH,those with AH were more likely to have a higher prevalence of DM(P<0.001)and hypertension(P=0.031)and presented with higher admission NIHSS scores(P<0.001).During the first 24 hours after IVT,END occurred in 208 patients(25.4%)and ENI occurred in 156 patients(19.0%).Multivariate mixed logistic regression analyses indicated that END was independently associated with AH[odds ratio(OR):1.744,95%confidence interval(CI):1.236-2.463;P=0.002].Subjects were classified into four groups representing quartiles.Compared with Q1,patients in the higher quartiles of SHR(Q2:OR:2.306,95%CI:1.342-3.960;P=0.002)(Q3:OR:2.284,95%CI:1.346-3.876;P=0.002)(Q4:OR:3.486,95%CI:2.088-5.820;P=0.001)and FBG(Q3:OR:1.746,95%CI:1.045-2.917;P=0.033)(Q4:OR:2.436,95%CI:1.476-4.022;P=0.001)had a significantly higher risk of END in the overall population.However,none of the glycemic indicators were found to be associated with ENI in patients with or without DM.CONCLUSION Our study demonstrated that glycemic indicators in patients with stroke treated with IVT were associated with the presence of END rather than ENI during the first 24 hours after admission.

Improving predictive accuracy of early recurrence in pancreatic ductal adenocarcinoma:Role of postoperative serum tumor markers

In a recent study by He et al,the nomogram integrates postoperative serum tumor markers such as carbohydrate antigen 19-9 and carcinoembryonic antigen,thereby improving the accuracy of identifying high-risk patients compared to relying solely on preoperative markers,which has significant implications for customizing adjuvant therapy and potentially improving outcomes for this aggressive form of cancer.However,the study’s single-center design and short follow-up period may limit the generalizability of its findings and potentially introduce reporting bias.Future studies could consider additional confounding factors,such as adjuvant chemotherapy and variations in surgical techniques,to improve the model’s accuracy.Furthermore,it would be valuable to validate the nomogram in broader,prospective cohorts and explore the inclusion of additional markers like circulating tumor DNA to refine further its predictive power and applicability across diverse patient populations.

Risk factors,monitoring,and treatment strategies for early recurrence after rectal cancer surgery

Early recurrence(ER)following surgery for rectal cancer is a significant factor impacting patient survival rates.Tsai et al identified age,preoperative neoadjuvant therapy,length of hospital stay,tumour location,and pathological stage as factors influencing the risk of ER.Postoperative monitoring for ER should encompass a thorough medical history review,physical examination,tumour marker testing,and imaging studies.Additionally,noninvasive circulating tumour cell DNA testing can be utilized to predict ER.Treatment strategies may involve radical surgery,radiation therapy,chemotherapy,and immunotherapy.Through a comprehensive analysis of risk factors,the optimization of monitoring methods,and the development of personalized treatment strategies,it is anticipated that both the efficacy of treatment and the quality of life for rectal cancer patients with postoperative recurrence can be significantly improved.

Improving the outcome in leukemia patients by controlling subthreshold depression and cancer-related fatigue

Patients with leukemia often suffer from the combined effects of cancer-related fatigue(CRF)and subthreshold depression,which mutually exacerbate each other in a vicious cycle.In this editorial,we comment on the article by Liu et al,published in the World Journal of Psychiatry.We further elucidate the profound impact of subthreshold depressive symptoms on the experience of CRF and complications in patients with leukemia.This editorial highlights the importance of early identification and treatment of subclinical depression,and advocates for a multidisciplinary and integrated treatment approach that includes social support,psychological interventions,and individualized treatment plans.Future research needs to explore the biological mechanisms underlying the interaction between the two to develop more effective prevention and treatment strategies.

Prediction of time-energy-location of microseismic events induced by deep coal-energy mining:Deep learning approach

Deep coal-energy mining frequently results in microseismic(MS)events,which may be a precursor to the risk of rockbursts and pose risks to human safety and infrastructure.Therefore,quantitatively predicting the time,energy,and location(TEL)of future MS events is crucial for understanding and preventing potential catastrophic events.In this study,we introduced the application of spatiotemporal graph convolutional networks(STGCN)to predict the TEL of MS events induced by deep coal-energy mining.Notably,this was the first application of graph convolution networks(GCNs)in the spatiotemporal prediction of MS events.The adjacency matrices of the sensor networks were determined based on the distance between MS sensors,the sensor network graphs we constructed,and GCN was employed to extract the spatiotemporal details of the graphs.The model is simple and versatile.By testing the model with on-site MS monitoring data,our results demonstrated promising efficacy in predicting the TEL of MS events,with the cosine similarity(C)above 0.90 and the mean relative error(MRE)below 0.08.This is critical to improving the safety and operational efficiency of deep coal-energy mining.

Insight into the efficacy and safety of pirfenidone: The treatment of idiopathic pulmonary fibrosis

Idiopathic pulmonary fibrosis(IPF)has a poor prognosis if left untreated;therefore,early treatment with pirfenidone is crucial.Lei et al conducted a retrospective analysis to evaluate the effectiveness of early pirfenidone treatment on lung function in 113 patients with IPF.In addition to other research,pirfeni-done has demonstrated efficacy in patients at all stages of IPF once correct diagnosis has been made.In advanced IPF,we include the requirement for pirfenidone.Therefore,it is essential to choose an appropriate method of adminis-tration method,such as inhalation.This may circumvent the drawbacks of the high cost and possible adverse effects of this drug.

Influence factors of clinical effects on patients with early gastric cancer:A retrospective study

BACKGROUND Identifying factors that influence non-curative resection(NCR)is critical to optimize treatment strategies and improve patient outcomes in patients with early gastric cancer(EGC).AIM To investigate the factors influencing the NCR of EGC and to evaluate the predictive value of these factors.METHODS The clinical data of 173 patients with EGC admitted between July 2020 and July 2023 were retrospectively collected.According to radical resection criteria,the patients were further divided into curative resection group(n=143)and NCR group(n=30).Clinical information was collected,including surgical method,tumor diameter,tumor site,ulcer formation,depth of invasion,pathological type,and lymph node metastasis.Logistic regression analysis was used to explore the factors affecting non-curable resection.RESULTS Multivariate logistic regression analysis showed that ulcer formation[odds ratio(OR)=3.53;95%confidence interval(CI):1.55-8.01,P=0.003],pathological type(OR=3.73;95%CI:1.60-8.74,P=0.002),tumor diameter(OR=3.15;95%CI:1.40-7.05,P=0.005),tumor location(OR=3.50;95%CI:1.16-10.58,P=0.027),lymph node metastasis(OR=4.40;95%CI:1.83-10.57,P=0.001),and depth of penetration(OR=3.75;95%CI:1.60-8.74,P=0.002)were all risk factors for NCR in EGC patients.Predictive analysis showed varying area under the curve values for factors such as tumor diameter(0.636),tumor location(0.608),ulcer formation(0.652),infiltration depth(0.658),pathological type(0.656),and lymph node metastasis(0.674).CONCLUSION The results suggest that factors such as tumor diameter,tumor location,ulcer formation,depth of invasion,pathological type,and lymph node metastasis increase the risk of NCR in EGC patients.
