With ECRS method, we can obtain the abnormal confidence attribute of data in different value ranges. Based on the relevancy spectrum in different studied time-intervals, we convert the original time sequence into relevancy time sequence, and can obtain the SMR time series by using the multi-point cumulative sliding mean method. Then we can identify the seismic precursor anomaly. We test this method by taking the time sequence of r/-value in the northern Tianshan region as original data. The result shows that when the studied time-interval is 18 months, the precursor anomaly can be identified bet- ter from sliding mean relevancy. The anomaly corresponding rate is 83 percent, the earthquake corresponding rate is 86 per- cent, and the anomaly is characteristic of the middle term. To try the research on multi-parameter comprehensive application, we take the Kalpin tectonic block in Xinjiang as our studied region, and analyze the spatial and temporal abnormal characters of multi-parameter sliding extreme-value relevancy （MSER） before mid-strong earthquakes in the Kalpin block. The result indicates that ECRS and SMR sequence in different time-intervals can not only be used to identify the precursor anomaly of single-item data, but also offer the data of quantitative single-item anomaly for comprehensive earthquake analysis and prediction.展开更多

The results of this research are shown as follows： （1） The timing relationship exists between MAC and VAC, and the frequency of VAC rises significantly in MAC year; （2） The relevancy exists in the earnings effects between MAC and VAC, and the combined effects which MAC and VAC have on earnings are in direct correlation with the earnings effects of MAC in the same year; （3） The supervisory factors of the securities market together with MAC influence the direction of VAC. Different from Pincus and Wasley＇s conclusion, when MAC is used to decrease profits, the part of VAC in our country counterbalances the effots of MAC; the listed companies with a special purpose will be against the direction of MAC and apply to VAC with a particular purpose.展开更多

For CoMP joint transmission （CoMP-JT） in heterogeneous scenario, if joint transmission （JT） users are firstly scheduled, other non-JT users will not be allocated sufficient resources, i.e., scheduling relevancy exists in the users under different cells in the same coordination cluster. However, the CoMP system throughput will decline remarkably, if the impact of scheduling relevancy is not considered. To address this issue, this paper proposes a novel scheduling scheme for CoMP in heterogeneous scenario. The principles of the proposed scheme include two aspects. Firstly, this scheme gives priority to user fairness, based on an extended proportional fairness （PF） scheduling algorithm. Secondly, the throughput of the coordination cluster should be maintained at a high level. By taking the non-CoMP system as a baseline, the proposed scheme is evaluated by comparing to random PF （RPF） and orthogonal PF （OPF） scheme. System-level simulation results indicate that, the proposed scheme can achieve considerable performance gain in both cell average and cell edge throughput.展开更多

Material and method: Analytical descriptive study with retrospective collection, extended from 1st January 2020 to 1st January 2022. Results: Of the 1000 transfontanellar ultrasound reports, the mean age of patients was 7.61 +/ 7.5 days, with extremes of zero and 28 days. Sex was specified in 989 cases. Males accounted for 54.49% and females for 45.51%. 555 transfontanellar ultrasound were performed in 2020. 441 in 2021 and 4 in 2022. 61.9% of transfontanellar ultrasound were performed at the Bogodogo University Hospital, 205 at Charles de Gaulle and 176 at Tengandogo. Indications for transfontanellar ultrasound were dominated by neonatal distress (65.8%), followed by convulsions (10.2%) and prematurity (9.1%). Transfontanellar ultrasound was normal in 570 cases (57%) and abnormal in 430 cases (43%). Abnormalities were dominated by haemorrhage and ischaemic lesions in 66.28% (285) and 21.63% (93) of cases respectively. In the group of normal transfontanellar ultrasound, neonatal distress represented 59.65% of indications and prematurity 10.7% of indications. As for abnormal transfontanellar ultrasound, neonatal suffering accounted for 73.95% of indications and convulsions for 12.56%. The average age ofpatients with an abnormal transfontanellar ultrasound was 8.74 days +/ 7.89 days. The indication for investigations was relevant in 42.2% of cases and irrelevant in 57.8%;of the transfontanellar ultrasound with relevant indications, 0.71 were normal and 99.29 abnormal;of the transfontanellar ultrasound with irrelevant indications, the transfontanellar ultrasound was normal in 98.1% and abnormal in 1.9%. Conclusion: Transfontanellar ultrasound is an important part of ultrasound in current practice. Haemorrhage, anoxic-ischaemic lesions and hydrocephalus are the most frequent pathologies found by this technique in newborns. Whether or not the examinations were normal depended on the appropriateness of the prescription.展开更多
文摘With the aim to the quantification of anomaly identification and extraction for observed or analyzed records, we present two statistical methods of earthquake corresponding relevancy spectrum （ECRS） and sliding mean relevancy （SMR）. With ECRS method, we can obtain the abnormal confidence attribute of data in different value ranges. Based on the relevancy spectrum in different studied time-intervals, we convert the original time sequence into relevancy time sequence, and can obtain the SMR time series by using the multi-point cumulative sliding mean method. Then we can identify the seismic precursor anomaly. We test this method by taking the time sequence of r/-value in the northern Tianshan region as original data. The result shows that when the studied time-interval is 18 months, the precursor anomaly can be identified bet- ter from sliding mean relevancy. The anomaly corresponding rate is 83 percent, the earthquake corresponding rate is 86 per- cent, and the anomaly is characteristic of the middle term. To try the research on multi-parameter comprehensive application, we take the Kalpin tectonic block in Xinjiang as our studied region, and analyze the spatial and temporal abnormal characters of multi-parameter sliding extreme-value relevancy （MSER） before mid-strong earthquakes in the Kalpin block. The result indicates that ECRS and SMR sequence in different time-intervals can not only be used to identify the precursor anomaly of single-item data, but also offer the data of quantitative single-item anomaly for comprehensive earthquake analysis and prediction.

文摘Coordinated multi-point （CoMP） transmission is a promising technique to improve both cell average and cell edge throughput for long term evolution-advanced （LTE-A）. For CoMP joint transmission （CoMP-JT） in heterogeneous scenario, if joint transmission （JT） users are firstly scheduled, other non-JT users will not be allocated sufficient resources, i.e., scheduling relevancy exists in the users under different cells in the same coordination cluster. However, the CoMP system throughput will decline remarkably, if the impact of scheduling relevancy is not considered. To address this issue, this paper proposes a novel scheduling scheme for CoMP in heterogeneous scenario. The principles of the proposed scheme include two aspects. Firstly, this scheme gives priority to user fairness, based on an extended proportional fairness （PF） scheduling algorithm. Secondly, the throughput of the coordination cluster should be maintained at a high level. By taking the non-CoMP system as a baseline, the proposed scheme is evaluated by comparing to random PF （RPF） and orthogonal PF （OPF） scheme. System-level simulation results indicate that, the proposed scheme can achieve considerable performance gain in both cell average and cell edge throughput.
文摘The minimal clinically important difference(MCID)represents a pivotal metric in bridging the gap between statistical significance and clinical relevance,addressing the direct impact of medical interventions from the patient's perspective.This comprehensive review analyzes the evolution,applications,and challenges of MCID across medical specialties,emphasizing its necessity in ensuring that clinical outcomes not only demonstrate statistical significance but also offer genuine clinical utility that aligns with patient expectations and needs.We discuss the evolution of MCID since its inception in the 1980s,its current applications across various medical specialties,and the methodologies used in its calculation,highlighting both anchor-based and distribution-based approaches.Furthermore,the paper delves into the challenges associated with the application of MCID,such as methodological variability and the interpretation difficulties that arise in clinical settings.Recommendations for the future include standardizing MCID calculation methods,enhancing patient involvement in setting MCID thresholds,and extending research to incorporate diverse global perspectives.These steps are critical to refining the role of MCID in patient-centered healthcare,addressing existing gaps in methodology and interpretation,and ensuring that medical interventions lead to significant,patient-perceived improvements.

文摘BACKGROUND The prevalence of lower extremity arteriosclerosis obliterans(LEASO)in China is progressively increasing with the increment in age.Certain patients may be diagnosed with lower extremity arterial stenosis and occlusion that resist complete curative efforts,which will invariably impose a substantial psychological strain on them.AIM To investigate the anxiety and depression conditions among patients with LEASO and analyze the associated risk factors.METHODS The Affiliated Hospital of Bengbu Medical University from January 2019 to December 2022.Their demographic and clinical data were obtained through the basic information questionnaire.The social support situation was assessed with the social support rating scale,and the hospital anxiety and depression scale were used to analyze their depression and anxiety levels.RESULTS The prevalence rate of anxiety was 44.0%among the 159 patients,with a total Self-Rating Anxiety Scale score of 49.01±9.65.The incidence of depression was 40.9%,and the total self-rating depression scale score reached 49.91±9.18.The overall social support score for all participants averaged 24.82±5.80.The correlation analysis between social support scores and anxiety and depression scores revealed that the total social support score,subjective social support,objective social support,as well as the degree of social support utilization,all exhibited a significant negative correlation with the anxiety and depression scores,which was statistically significant(P<0.05).The univariate analysis revealed statistically significant differences in the depression and anxiety states among patients with varying pain manifestations,disease stages,disease durations,and social support magnitudes(P<0.05).The multivariate analysis further demonstrated that patients presenting with intermittent claudication,rest pain,and pain,whose disease course was within half a year,and who had relatively low social support,were more predisposed to anxiety.Intriguingly,a monthly income of>6000 yuan was considered a protective factor in this context(P<0.05).Similarly,patients with intermittent claudication,rest pain,gangrene,and pain,and who had relatively low social support,were more liable to succumb to depressive moods(P<0.05).CONCLUSION Patients with LEASO typically receive relatively scant social support.Notably,those who concurrently present with symptoms,such as pain,claudication,and gangrene,are at a substantially increased risk of developing depression and anxiety disorders.A significant negative correlation is manifested between the social support level that patients receive and the severity of their anxiety and depression symptoms.Hence,the lower the social support score,the greater the propensity for patients to experience anxiety and depressive emotions.Therefore,during clinical practice,the crucial role that social support plays in safeguarding patients’physical and mental well-being as well as facilitating the effectiveness of disease treatment needs to be particularly emphasized.

文摘In the context of global aging,mild behavioral impairment(MBI)is present in 48.9%of patients with mild cognitive impairment(MCI).MBI,a neurobehavioral syndrome in the elderly,is an independent risk factor for cognitive decline and is closely related to peripheral blood biomarkers associated with Alzheimer's disease,offering new diagnostic and interventional avenues for early MCI.To summarize evidence on peripheral blood biomarkers related to MBI and their underlying mechanisms involving neuroinflammation,tau pathology,and oxidative stress,a systematic review of studies published between 2015 and 2024 was conducted.MBI is closely associated with peripheral blood biomarker changes.Neuroinflammatory markers like glial fibrillary acidic protein and neurofilament light indicate astrocyte activation and neural circuit disruption,with glial fibrillary acidic protein levels correlating with impulse dyscontrol scores.Chitinase-3-like protein 1,a marker of blood-brain barrier integrity,exacerbates neuroinflammation and is linked to depressive symptoms and hippocampal atrophy.Elevated phosphorylated tau proteins in blood correlate with brain tau deposition,increasing the risk of MBI and impairing cognition.Oxidative stress markers damage neurons and disrupt neurotransmission,and concurrent alterations in malondialdehyde and superoxide dismutase levels significantly elevate the risk of MBI.The correlation between MBI and biomarkers offers new diagnostic and interventional directions for early MCI.Future research should standardize MBI assessment,conduct longitudinal studies,explore biomarker-MBI relationships,investigate psychosocial impacts,and develop advanced detection methods.

文摘Given the severe toxicity and widespread presence of cadmium(Cd)in staple foods such as rice,accurate dietary exposure assessments are imperative for public health.In vitro bioavailability is commonly used to adjust dietary exposure levels of risk factors;however,traditional planar Transwell models have limitations,such as cell dedifferentiation and lack of key intestinal components,necessitating a more physiologically relevant in vitro platform.This study introduces an innovative three-dimensional(3D)intestinal organoid model using a microfluidic chip to evaluate Cd bioavailability in food.Caco-2 cells were cultured on the chip to mimic small intestinal villi's 3D structure,mucus production,and absorption functions.The model's physiological relevance was thoroughly characterized,demonstrating the formation of a confluent epithelial monolayer with well-developed tight junctions(ZO-1),high microvilli density(F-actin),and significant mucus secretion(Alcian blue staining),closely resembling the physiological intestinal epithelium.Fluorescent particle tracking confirmed its ability to simulate intestinal transport and diffusion.The Cd bioavailability in rice measured by the 3D intestinal organoid model((9.07±0.21)%)was comparable to the mouse model((12.82±3.42)%)but significantly lower than the Caco-2 monolayer model((26.97±1.11)%).This 3D intestinal organoid model provides a novel and reliable strategy for in vitro assessment of heavy metal bioavailability in food,with important implications for food safety and risk assessment.
文摘BACKGROUND Middle pancreatectomy(MP)is a surgical procedure that removes non-invasive lesions in the pancreatic neck and body,allowing for the preservation of pan-creatic function.However,MP is associated with a higher risk of postoperative complications,and there’s no clear consensus on which anastomotic method is preferable.In recent years,our team has developed a new method called inter-locking main pancreatic duct-jejunal(IMPD-J)internal bridge drainage to MP.AIM To compare perioperative and postoperative outcomes in patients who underwent IMPD-J bridge drainage and those underwent traditional duct-to-mucosa pancreatojejunostomy.METHODS Patients who underwent MP in our hospital between October 1,2011 and July 31,2023 were enrolled in this study.Patients were divided into two groups based on their pancreatojejunostomy technique:IMPD-J bridge drainage group and duct-to-mucosa pancreatojejunostomy group.Demographic data(age,gender,body mass index,hypertension,diabetes,etc.)and perioperative indicators[operation time,intraoperative bleeding,clinically relevant postoperative pancreatic fistula(CR-POPF),delayed gastric emptying,etc.]were recorded and analyzed statist-ically.RESULTS A total of 53 patients were enrolled in this study,including 23 in the IMPD-J Bridge Drainage group and 30 in the traditional duct-to-mucosa pancreatojejun-ostomy group.There were no significant differences in demographic or preope-rative characteristics between the groups.Compared to traditional duct-to-mucosa pancreaticojejunostomy,IMPD-J bridge drainage had a significant shorter operation time(4.3±1.3 hours vs 5.8±1.8 hours,P=0.002),nasogastric tube retention days(5.3±1.7 days vs 6.5±2.0 days,P=0.031),lower incidence of delayed gastric emptying(8.7%vs 36.7%,P=0.019),and lower incidence of CR-POPF(39.1%vs 70.0%,P=0.025).Multivariate logistic regression analysis showed that pancreaticojejunostomy type(odds ratio=4.219,95%confidence interval=1.238-14.379,P=0.021)and plasma prealbumin(odds ratio=1.132,95%confidence interval=1.001-1.281,P=0.049)were independent risk factor for CR-POPF.In IMPD-J bridge drainage group,only one patient experienced recurrent pancreatitis due to the large diameter of the silicone tube and had it removed six months after surgery.CONCLUSION Compared to traditional duct-to-mucosa pancreatojejunostomy,IMPD-J bridge drainage has the advantages of simplicity and fewer perioperative complications,with favorable long-term outcomes.

文摘Audio-visual scene classification(AVSC)poses a formidable challenge owing to the intricate spatial-temporal relationships exhibited by audio-visual signals,coupled with the complex spatial patterns of objects and textures found in visual images.The focus of recent studies has predominantly revolved around extracting features from diverse neural network structures,inadvertently neglecting the acquisition of semantically meaningful regions and crucial components within audio-visual data.The authors present a feature pyramid attention network(FPANet)for audio-visual scene understanding,which extracts semantically significant characteristics from audio-visual data.The authors’approach builds multi-scale hierarchical features of sound spectrograms and visual images using a feature pyramid representation and localises the semantically relevant regions with a feature pyramid attention module(FPAM).A dimension alignment(DA)strategy is employed to align feature maps from multiple layers,a pyramid spatial attention(PSA)to spatially locate essential regions,and a pyramid channel attention(PCA)to pinpoint significant temporal frames.Experiments on visual scene classification(VSC),audio scene classification(ASC),and AVSC tasks demonstrate that FPANet achieves performance on par with state-of-the-art(SOTA)approaches,with a 95.9 F1-score on the ADVANCE dataset and a relative improvement of 28.8%.Visualisation results show that FPANet can prioritise semantically meaningful areas in audio-visual signals.

文摘BACKGROUND Traumatic brain injury(TBI)imposes a substantial societal and familial burden due to its high disability and fatality rates,rendering it a serious public health problem.Some patients with TBI have poor treatment outcomes and are prone to postoperative delirium(POD),which affects their quality of life.Anxiety has been linked to increased POD incidence in some studies,while others have found no correlation.AIM To investigate the correlation of POD risk factors,preoperative inflammatory factors,and mood disorders in patients with TBI.METHODS We retrospectively collected data on the treatment of 80 patients with TBI from November 2021 to September 2023.Patients were grouped as POD and non-POD,according to their POD status,and the general data of the two groups were compared.Inflammatory factor levels were detected preoperatively,and the Hamilton Depression Scale(HAMD)and Hamilton Anxiety Scale(HAMA)were used to investigate the risk factors associated with POD in these patients.Logistic regression was used to identify the independent risk factors.RESULTS Twenty-one patients(26.25%)developed POD,including 7,10,and 4 cases of the excitatory,inhibitory,and mixed types,respectively.There were 59 cases(73.75%)in the non-POD group.Compared with the non-POD group,the POD group had a significantly higher proportion of patients with low Glasgow Coma Scale(GCS)scores before admission,unilateral mydriasis,preoperative hemorrhagic shock,intraventricular hemorrhage(IVH),and postoperative hyperglycemic hyperosmolar disease(P<0.05).In the POD group,interleukin-6(IL-6),human tumor necrosis factor-α(TNF-α),myeloperoxidase levels,HAMA,and HAMD scores were higher than those in the non-POD group(all P<0.05).Logistic multivariate analysis showed that GCS score at admission,IVH,IL-6,TNF-α,HAMA,and HAMD were independent risk factors for POD in patients with TBI(P<0.05).CONCLUSION Low GCS score at admission,IVH,elevated IL-6 and TNF-α,other inflammatory indicators,anxiety,and depression,can increase the risk of POD in patients with TBI after surgery.

文摘The research aims to improve the performance of image recognition methods based on a description in the form of a set of keypoint descriptors.The main focus is on increasing the speed of establishing the relevance of object and etalon descriptions while maintaining the required level of classification efficiency.The class to be recognized is represented by an infinite set of images obtained from the etalon by applying arbitrary geometric transformations.It is proposed to reduce the descriptions for the etalon database by selecting the most significant descriptor components according to the information content criterion.The informativeness of an etalon descriptor is estimated by the difference of the closest distances to its own and other descriptions.The developed method determines the relevance of the full description of the recognized object with the reduced description of the etalons.Several practical models of the classifier with different options for establishing the correspondence between object descriptors and etalons are considered.The results of the experimental modeling of the proposed methods for a database including images of museum jewelry are presented.The test sample is formed as a set of images from the etalon database and out of the database with the application of geometric transformations of scale and rotation in the field of view.The practical problems of determining the threshold for the number of votes,based on which a classification decision is made,have been researched.Modeling has revealed the practical possibility of tenfold reducing descriptions with full preservation of classification accuracy.Reducing the descriptions by twenty times in the experiment leads to slightly decreased accuracy.The speed of the analysis increases in proportion to the degree of reduction.The use of reduction by the informativeness criterion confirmed the possibility of obtaining the most significant subset of features for classification,which guarantees a decent level of accuracy.
文摘BACKGROUND The minimal clinically important difference(MCID)is defined as the smallest meaningful change in a health domain that a patient would identify as important.Thus,an improvement that exceeds the MCID can be used to define a successful treatment for the individual patient.AIM To quantify the rate of clinical improvement following anatomical total shoulder arthroplasty for glenohumeral osteoarthritis.METHODS Patients were treated with the Global Unite total shoulder platform arthroplasty between March 2017 and February 2019 at Herlev and Gentofte Hospital,Denmark.The patients were evaluated preoperatively and 3 months,6 months,12 months,and 24 months postoperatively using the Western Ontario Osteoarthritis of the Shoulder index(WOOS),Oxford Shoulder Score(OSS)and Constant-Murley Score(CMS).The rate of clinically relevant improvement was defined as the proportion of patients who had an improvement 24 months postoperatively that exceeded the MCID.Based on previous literature,MCID for WOOS,OSS,and CMS were defined as 12.3,4.3,and 12.8 respectively.RESULTS Forty-nine patients with a Global Unite total shoulder platform arthroplasty were included for the final analysis.Mean age at the time of surgery was 66 years(range 49.0-79.0,SD:8.3)and 65%were women.One patient was revised within the two years follow-up.The mean improvement from the preoperative assessment to the two-year follow-up was 46.1 points[95%confidence interval(95%CI):39.7-53.3,P<0.005]for WOOS,18.2 points(95%CI:15.5-21.0,P<0.005)for OSS and 37.8 points(95%CI:31.5-44.0,P<0.005)for CMS.Two years postoperatively,41 patients(87%)had an improvement in WOOS that exceeded the MCID,45 patients(94%)had an improvement in OSS that exceeded the MCID,and 42 patients(88%)had an improvement in CMS that exceeded the MCID.CONCLUSION Based on three shoulder-specific outcome measures we find that approximately 90%of patients has a clinically relevant improvement.This is a clear message when informing patients about their prognosis.
文摘Objectives: To demonstrate the contribution and relevance of ETFs through the study of 1000 examination reports carried out in the medical imaging departments of the OUAGADOUGOU CHU. Material and method: Analytical descriptive study with retrospective collection, extended from 1st January 2020 to 1st January 2022. Results: Of the 1000 transfontanellar ultrasound reports, the mean age of patients was 7.61 +/ 7.5 days, with extremes of zero and 28 days. Sex was specified in 989 cases. Males accounted for 54.49% and females for 45.51%. 555 transfontanellar ultrasound were performed in 2020. 441 in 2021 and 4 in 2022. 61.9% of transfontanellar ultrasound were performed at the Bogodogo University Hospital, 205 at Charles de Gaulle and 176 at Tengandogo. Indications for transfontanellar ultrasound were dominated by neonatal distress (65.8%), followed by convulsions (10.2%) and prematurity (9.1%). Transfontanellar ultrasound was normal in 570 cases (57%) and abnormal in 430 cases (43%). Abnormalities were dominated by haemorrhage and ischaemic lesions in 66.28% (285) and 21.63% (93) of cases respectively. In the group of normal transfontanellar ultrasound, neonatal distress represented 59.65% of indications and prematurity 10.7% of indications. As for abnormal transfontanellar ultrasound, neonatal suffering accounted for 73.95% of indications and convulsions for 12.56%. The average age ofpatients with an abnormal transfontanellar ultrasound was 8.74 days +/ 7.89 days. The indication for investigations was relevant in 42.2% of cases and irrelevant in 57.8%;of the transfontanellar ultrasound with relevant indications, 0.71 were normal and 99.29 abnormal;of the transfontanellar ultrasound with irrelevant indications, the transfontanellar ultrasound was normal in 98.1% and abnormal in 1.9%. Conclusion: Transfontanellar ultrasound is an important part of ultrasound in current practice. Haemorrhage, anoxic-ischaemic lesions and hydrocephalus are the most frequent pathologies found by this technique in newborns. Whether or not the examinations were normal depended on the appropriateness of the prescription.
