Abstract Introduction Spontaneous intracerebral hemorrhage (ICH) is one of leading causes mortality and morbidity worldwide. Several predictive models have been developed for ICH; however, none them consistently used in routine clinical practice or research. In the study, we aimed to develop validate a risk score predicting 1-year functional outcome after ICH (ICH Functional Outcome Score, ICH-FOS). Furthermore, compared discrimination ICH-FOS 8 existing scores with regard 30-day, 3-month,...
NO oxidation using O3 is studied, including the product composition under different conditions and selectivity in complex flue gas. The O3/NO molar ratio determines type of products. N2O5 generated when greater than 1, yield increases with improvement ratio. High temperature leads to decomposition NO3 decrease yield. When caused high-temperature region, increase residence time not beneficial generation N2O5. In addition, water vapor gas formation at low temperatures (60–90 °C), but SO2, CO,...
Coal, as an unconventional reservoir, is characterized by the development of micro/nano-meter pores and significant pore differences in different bedding directions. Pore heterogeneity anisotropy are key factors contributing to difference reservoir properties. This not only affects recovery resources but also interpretation seismic data. Currently, research on coal mainly focuses distribution. Nonetheless, there few studies a lack comprehensive knowledge regarding connectivity within same...
ABSTRACT Objectives To compare the discrimination and calibration of six risk scoring systems in assessment patients with stroke‐associated pneumonia (SAP) after acute ischemic stroke. Methods The validation cohort was derived from Third China National Stroke Registry. SAP diagnosed according to criteria for hospital‐acquired Centers Disease Control Prevention. area under receiver operating characteristic curve (AUROC) Hosmer‐Lemeshow goodness‐of‐fit test were used assess calibration....
Background and Purpose— We aimed to develop a risk score (intracerebral hemorrhage–associated pneumonia score, ICH-APS) for predicting hospital-acquired stroke-associated (SAP) after ICH. Methods— The ICH-APS was developed based on the China National Stroke Registry (CNSR), in which eligible patients were randomly divided into derivation (60%) validation (40%) cohorts. Variables routinely collected at presentation used SAP For testing added value of hematoma volume measure, we separately 2...
Objective This study aimed to examine the relationship between lipoprotein (a) (Lp[a]) and other blood lipid indexes carotid artery atherosclerosis in patients with acute ischemic stroke (AIS). Methods A total of 2,018 were selected from hospital “acute intervention secondary prevention registration database” by identifying fat (cholesterol, triglyceride, high-density cholesterol, low-density cholesterol Lp[a]). Based on results ultrasound examinations, divided into a “no plaque” group,...
<i>Background:</i> Despite accumulating evidence supporting the association between variants of the<i> ALOX5AP</i> gene and atherosclerotic vascular events, precise mechanism is still unclear. No in coding sequence that lead to amino acid substitution have been found. We investigated genetic promoter region <i>ALOX5AP</i> with ischemic stroke a north Chinese Han population. <i>Methods:</i> 505 cases 500 age- gender-matched controls population...
Studies showed that patients with hemorrhagic stroke are at a higher risk of developing deep vein thrombosis (DVT) than those ischemic stroke. We aimed to develop score (intracerebral hemorrhage-associated score, ICH-DVT) for predicting in-hospital DVT after ICH. The ICH-DVT was developed based on the Beijing Registration Intracerebral Hemorrhage, in which eligible were randomly divided into derivation (60%) and internal validation cohorts (40%). External performed using iMCAS study...
Medical complications strongly affected the mortality of patients with stroke. However, only limited research has studied effect in-hospital medical on spontaneous intracerebral haemorrhage (ICH) globally. Using China National Stroke Registry, was prospectively and systematically investigated in ICH during their hospitalisation, at 3, 6 12 months after disease onset.This study collected data over 18 years old from 132 Chinese clinical centres across 32 provinces four municipalities (Hong...
To systematically compare 27 ICH models with regard to mortality and functional outcome at 1-month, 3-month 1-year after ICH. The validation cohort was derived from the Beijing Registration of Intracerebral Hemorrhage. Poor defined as modified Rankin Scale score (mRS) ≥3 ICH, respectively. area under receiver operating characteristic curve (AUROC) Hosmer-Lemeshow goodness-of-fit test were used assess model discrimination calibration. A total number 1575 patients included. mean age 57.2 ±...
The early hematoma expansion of intracerebral hemorrhage (ICH) indicates a poor prognosis. This paper studies the relationship between cerebral blood flow (CBF) around and (HE) in acute stage hemorrhage. A total 50 patients with supratentorial were enrolled this study. They underwent baseline whole-brain CTP within 6 h after hemorrhage, non-contrast CT 24 h. Absolute growth relative calculated, respectively. Hematoma volume >33% was considered to be expansion. Ipsilateral peri-edema CBF...
Background and Purpose The quality of after-hour emergency care patients with acute ischemic stroke is debatable. We therefore, sought to analyze the performance measures, clinical outcomes in these admitted during off-hours. Methods Our study included 4493 from a selected cohort hospitals China National Stroke Registry (CNSR) September 2007 August 2008. On-hour presentation was defined as arrival at department scene between 8AM 5PM Monday through Friday. Off-hours remainder on-hours...
Abstract Inertinite‐rich coal is widely distributed in the Ordos Basin, represented by No. 2 seam of Middle Jurassic Yan'an Formation. This paper combined petrology and geochemistry to analyze origin inertinite, changes coal‐forming environment control characteristics wildfire. Research has shown that there are two forms inertinite sources study area. Alongside typical fusinization, wildfire events also play a substantial role formation. There significant fluctuations samples at different...
Full 3D interpretation must be based on really full horizons interpretation. In this paper, we used mathematical model of the similarity principle which express characterization waveform seismic data, and analyzed effect parameters recognition, then applied method to auto-track reflected wave coalseam in exploration Liliangdian mining area. The results show that refers not only a conventional amplitude waveform, but also attributes such as phase, frequency variance etc. selection is...
