Methods： A total of 582 traces of pressure-flow study from 181 men with BPH was included in the study. For each trace, maximum urinary flow rate （Qmax） and detrusor pressure at Qmax （pdet.Qmax） were, respectively, read from manually smoothed and corrected uroflow and detrusor pressure curves from the computer print-outs. Obstruction coefficient, International Continence Society （ICS） and Schaefer nomograms were used to detect urethral resistance and to diagnose obstruction. The results obtained by manual reading were compared with those from computer-based systems. Results： After manual correction, Qmax underwent a consistently significant decrease by 1.2 mL/s on average （P 〈 0.001）, and had a change range of 0.5-10.4 mL/s. However, pdet.Qmax underwent inconsistently intra-individual changes after correction. The obstruction coefficient increased significantly, by an average of 0.07 （P 〈 0.05）. Using the ICS nomogram, the percentage of obstruction increased from 69.8% to 73.9%, and of the non-obstruction decreased from 8.8% to 5.3% （P 〈 0.05）. There were 11% of traces that changed the classifications using the ICS nomogram, and 28.9% that changed the grades for the Schaefer nomogram. Conclusion： Systematically significant differences in parameters from pres- sure-flow study between manual readings and computer recordings were demonstrated. Manual correction resulted in a consistently lower Q a higher urethral resistance, and an aggravating obstruction. Manual readings can correct considerable false diagnoses for obstruction. Retrospective quality control of pressure-flow data with com- puter-based systems is necessary.展开更多

文摘The existence of outliers can seriously influence the analysis of variational data assimilation.Quality control allows us to effectively eliminate or absorb these outliers to produce better analysis fields.In particular,variational quality control(VarQC) can process gray zone outliers and is thus broadly used in variational data assimilation systems.In this study,governing equations are derived for two VarQC algorithms that utilize different contaminated Gaussian distributions(CGDs): Gaussian plus flat distribution and Huber norm distribution.As such,these VarQC algorithms can handle outliers that have non-Gaussian innovations.Then,these VarQC algorithms are implemented in the Global/Regional Assimilation and PrEdiction System(GRAPES) model-level three-dimensional variational data assimilation(m3 DVAR) system.Tests using artificial observations indicate that the VarQC method using the Huber distribution has stronger robustness for including outliers to improve posterior analysis than the VarQC method using the Gaussian plus flat distribution.Furthermore,real observation experiments show that the distribution of observation analysis weights conform well with theory,indicating that the application of VarQC is effective in the GRAPES m3 DVAR system.Subsequent case study and longperiod data assimilation experiments show that the spatial distribution and amplitude of the observation analysis weights are related to the analysis increments of the mass field(geopotential height and temperature).Compared to the control experiment,VarQC experiments have noticeably better posterior mass fields.Finally,the VarQC method using the Huber distribution is superior to the VarQC method using the Gaussian plus flat distribution,especially at the middle and lower levels.
文摘Aim： To evaluate the effects of retrospective quality control on pressure-flow data with computer-based urodynamic systems from men with benign prostatic hyperplasia （BPH）. Methods： A total of 582 traces of pressure-flow study from 181 men with BPH was included in the study. For each trace, maximum urinary flow rate （Qmax） and detrusor pressure at Qmax （pdet.Qmax） were, respectively, read from manually smoothed and corrected uroflow and detrusor pressure curves from the computer print-outs. Obstruction coefficient, International Continence Society （ICS） and Schaefer nomograms were used to detect urethral resistance and to diagnose obstruction. The results obtained by manual reading were compared with those from computer-based systems. Results： After manual correction, Qmax underwent a consistently significant decrease by 1.2 mL/s on average （P 〈 0.001）, and had a change range of 0.5-10.4 mL/s. However, pdet.Qmax underwent inconsistently intra-individual changes after correction. The obstruction coefficient increased significantly, by an average of 0.07 （P 〈 0.05）. Using the ICS nomogram, the percentage of obstruction increased from 69.8% to 73.9%, and of the non-obstruction decreased from 8.8% to 5.3% （P 〈 0.05）. There were 11% of traces that changed the classifications using the ICS nomogram, and 28.9% that changed the grades for the Schaefer nomogram. Conclusion： Systematically significant differences in parameters from pres- sure-flow study between manual readings and computer recordings were demonstrated. Manual correction resulted in a consistently lower Q a higher urethral resistance, and an aggravating obstruction. Manual readings can correct considerable false diagnoses for obstruction. Retrospective quality control of pressure-flow data with com- puter-based systems is necessary.

文摘Glaucoma is an eye disease characterized by pathologically elevated intraocular pressure,optic nerve atrophy,and visual field defects,which can lead to irreversible vision loss.In recent years,the rapid development of artificial intelligence(AI)technology has provided new approaches for the early diagnosis and management of glaucoma.By classifying and annotating glaucoma-related images,AI models can learn and recognize the specific pathological features of glaucoma,thereby achieving automated imaging analysis and classification.Research on glaucoma imaging classification and annotation mainly involves color fundus photography(CFP),optical coherence tomography(OCT),anterior segment optical coherence tomography(AS-OCT),and ultrasound biomicroscopy(UBM)images.CFP is primarily used for the annotation of the optic cup and disc,while OCT is used for measuring and annotating the thickness of the retinal nerve fiber layer,and AS-OCT and UBM focus on the annotation of the anterior chamber angle structure and the measurement of anterior segment structural parameters.To standardize the classification and annotation of glaucoma images,enhance the quality and consistency of annotated data,and promote the clinical application of intelligent ophthalmology,this guideline has been developed.This guideline systematically elaborates on the principles,methods,processes,and quality control requirements for the classification and annotation of glaucoma images,providing standardized guidance for the classification and annotation of glaucoma images.

文摘Age-related macular degeneration(AMD)is a disease that affects the vision of elderly individuals worldwide.Although current therapeutics have shown effectiveness against AMD,some patients may remain unresponsive and continue to experience disease progression.Therefore,in-depth knowledge of the mechanism underlying AMD pathogenesis is urgently required to identify potential drug targets for AMD treatment.Recently,studies have suggested that dysfunction of mitochondria can lead to the aggregation of reactive oxygen species(ROS)and activation of the cyclic GMP-AMP synthase(cGAS)/stimulator of interferon genes(STING)innate immunity pathways,ultimately resulting in sterile inflammation and cell death in various cells,such as cardiomyocytes and macrophages.Therefore,combining strategies targeting mitochondrial dysfunction and inflammatory mediators may hold great potential in facilitating AMD management.Notably,emerging evidence indicates that natural products targeting mitochondrial quality control(MQC)and the cGAS/STING innate immunity pathways exhibit promise in treating AMD.Here,we summarize phytochemicals that could directly or indirectly influence the MQC and the cGAS/STING innate immunity pathways,as well as their interconnected mediators,which have the potential to mitigate oxidative stress and suppress excessive inflammatory responses,thereby hoping to offer new insights into therapeutic interventions for AMD treatment.

文摘Diabetic foot ulcer(DFU)is an increasing global burden due to the rising prevalence of diabetes,and no specific pharmacological targets or satisfactory drugs are currently available for this devastating ailment.In this study,naringenin(NAR)was found to accelerate diabetic wound healing in diabetic C57BL/6J wild-type(WT)mice by reducing oxidative stress,as assessed through histological assay.NAR also alleviated the inhibition of proliferation,inflammation,cell senescence,and apoptosis in HaCaT cells induced by high glucose(HG).Mechanistically,the beneficial effects of NAR on wound healing are dependent on the E3 ubiquitin-protein ligase parkin(Parkin/PRKN/Prkn).NAR upregulated the expression level of Parkin and promoted its mitochondrial translocation,thereby activating Parkin-mediated mitophagy and maintaining mitochondrial quality control(MQC).Moreover,the wound healingpromoting effects of NAR were significantly diminished in Parkin knockdown HaCaT cells and Prkn knockout(Prkn^(-/-))DFU mice.Inhibition of NAR binding to estrogen receptors(ERs)using tamoxifen(TAM)abolished the protective effects of NAR in HG-induced HaCaT cells.The luciferase reporter assay confirmed that NAR enhanced ERs binding to the estrogen response element(ERE),thereby upregulating Parkin transcription.Additionally,the cellular thermal shift assay(CETSA)revealed that NAR specifically bound to ERa.In conclusion,NAR promoted DFU wound healing by enhancing Parkin-mediated mitophagy via binding to ERa,highlighting its potential as a promising therapeutic candidate.
