Background: and Purpose This study aimed to investigate the association between residual inflammatory risk (RIR) and vulnerable plaques using high-resolution magnetic resonance imaging (HRMRI) in symptomatic intracranial atherosclerotic stenosis (ICAS). Methods: This retrospective study included 70%–99% symptomatic ICAS patients hospitalized from January 2016 to December 2022. Patients were classified into four groups based on high-sensitivity C-reactive protein (hs-CRP) and low-density lipoprotein cholesterol (LDL-C): residual cholesterol inflammatory risk (RCIR, hs-CRP ≥3 mg/L and LDL-C ≥2.6 mmol/L), RIR (hs-CRP ≥3 mg/L and LDL-C <2.6 mmol/L), residual cholesterol risk (RCR, hs-CRP <3 mg/L and LDL-C ≥2.6 mmol/L), and no residual risk (NRR, hs-CRP <3 mg/L and LDL-C <2.6 mmol/L). Vulnerable plaque features on HRMRI included positive remodeling, diffuse distribution, intraplaque hemorrhage, and strong enhancement. Results: Among 336 included patients, 21, 60, 58, and 197 were assigned to the RCIR, RIR, RCR, and NRR groups, respectively. Patients with RCIR (adjusted odds ratio [aOR], 3.606; 95% confidence interval [CI], 1.346–9.662; P=0.011) and RIR (aOR, 3.361; 95% CI, 1.774–6.368, P<0.001) had higher risks of strong enhancement than those with NRR. Additionally, patients with RCIR (aOR, 2.965; 95% CI, 1.060–8.297; P=0.038) were more likely to have intraplaque hemorrhage compared with those with NRR. In the sensitivity analysis, RCR (aOR, 2.595; 95% CI, 1.201–5.608; P=0.015) exhibited an additional correlation with an increased risk of intraplaque hemorrhage. Conclusion In patients with symptomatic ICAS, RIR is associated with a higher risk of intraplaque hemorrhage and strong enhancement, indicating an increased vulnerability to atherosclerotic plaques.

Objective To develop and validate a prediction model for severe disability or death(SDD)in acute ischemic stroke(AIS)patients who underwent endovascular treatment(EVT).Methods Based on the dataset of ANGEL-ACT study who received EVT for AIS between november 2017 and march 2019,a retrospective analysis was performed on 1 677 patients,including 1 111 males and 566 females,aged ≥ 18 years.Patients were divided into two groups according to whether SDD occurred(mRS 5-6 scores 90 days after surgery):SDD group(n=478)and non-SDD group(n=1 199).Risk factors that might influence SDD after EVT in AIS patients were screened and analyzed by multifactorial analysis,LAS-SO regression,and RF-RFE methods.A nomogram was developed after evaluating the model performance and the execution of internal validation.Results SDD occurred in 380(28.1％)patients in the develop-ment cohort and 98(30.2％)patients in the validation cohort.Combining the three variable screening meth-ods,10 risk factors were selected for inclusion in the final model:age,NIHSS score,whether successful re-canalization,glucose level,hemoglobin,hematocrit,onset to puncture time,systolic blood pressure,AS-PECT score,and whether have treatment-related serious adverse events.A two-stage model means that model 1 contains pre-treatment variables(7 in total)and model 2 contains pre-treatment and post-treatment variables(10 in total).The area under the curve(AUC)of model 1 in the development cohort was 0.705(95％CI 0.674-0.736)and 0.731(95％CI 0.701-0.760)in model 2.Both models had good calibration with aslope of 1.000,and the decision curve analysis showed good clinical applicability.The results of the validation cohort were similar to those of the development cohort.Conclusion Age,admission NIHSS score,whether successful recanalization,admission glucose level,hemoglobin content,erythrocyte pressure volume,onset to puncture time,admission systolic blood pressure,ASPECT score,and whether have treat-ment-related serious adverse events are risk factors for SDD in patients with acute ischemic stroke.The two prediction models based on the above factors were used before and after endovascular treatment to predict SDD occurrence better.

Objective: To investigate the contamination of phthalic acid esters (PAEs) and assess the health risk of PAEs contamination in market-available yellow rice wine in Huzhou City, Zhejiang Province, so as to provide the safety safeguard for consuming yellow rice wine. Methods: Yellow rice wine samples were collected from markets in Huzhou City from 2021 to 2022, and 16 PAEs were determined in yellow rice wine using magnetic solid-phase extraction coupled with gas chromatography-tandem mass spectrometry. The carcinogenic and non-carcinogenic risks of PAEs were evaluated using the health risk models proposed by United States Environmental Protection Agency. Results: A total of 75 yellow rice wine samples were collected, and 44 samples were detected with PAEs contamination (58.67%). Dimethyl phthalate (DMP), di-isobutyl phthalate (DIBP) and di-butyl phthalate (DBP) were detected, and there were 17 samples (22.67%) detected with DBP overdose (DMP and DIBP had no limit standard). DMP, DBP and DIBP, which were not classified as Class 2B and higher carcinogens by WHO's International Agency for Research on Cancer, had no definitive carcinogenic risks. Under mean PAEs, the five types of yellow rice wine all had no carcinogenic risks. Under 75% percentile of PAEs concentrations, the DBP in beverage wine with plastic packaging had a carcinogenic risk score of 1.207 5, with a gross carcinogenic risk score of 1.207 5. Under the maximum PAEs concentration, the ross carcinogenic risk scores of cooking wine with plastic packaging, beverage wine with plastic packaging, beverage wine with glass bottle packaging, and beverage wine with jar packaging were 2.751 0, 2.782 0, 1.298 2 and 2.944 0, presenting non-carcinogenic risks. Conclusion There is PAEs contamination in market-available yellow rice wine in Huzhou City, and no carcinogenic risk is evaluated. Non-carcinogenic health risk requires to be given a high priority.

Background: and Purpose Intracranial vertebrobasilar atherosclerotic stenosis (IVBAS) is a major cause of posterior circulation stroke. Some patients suffer from stroke recurrence despite receiving medical treatment. This study aimed to determine the prognostic value of a new score for the posterior communicating artery and the P1 segment of the posterior cerebral artery (PCoA-P1) for predicting stroke recurrence in IVBAS. Methods: We retrospectively enrolled patients with severe IVBAS (70%–99%). According to the number of stroke recurrences, patients were divided into no-recurrence, single-recurrence, and multiple-recurrences groups. We developed a new 5-point grading scale, with the PCoA-P1 score ranging from 0 to 4 based on magnetic resonance angiography, in which primary collaterals were dichotomized into good (2–4 points) and poor (0 or 1 point). Stroke recurrences after the index stroke were recorded. Patients who did not experience stroke recurrence were compared with those who experienced single or multiple stroke recurrences. Results: From January 2012 to December 2019, 176 patients were enrolled, of which 116 (65.9%) had no stroke recurrence, 35 (19.9%) had a single stroke recurrence, and 25 (14.2%) had multiple stroke recurrences. Patients with single stroke recurrence (odds ratio [OR]= 4.134, 95% confidence interval [CI]=1.822–9.380, p=0.001) and multiple stroke recurrences (OR=6.894, 95% CI=2.489–19.092, p<0.001) were more likely to have poor primary collaterals than those with no stroke recurrence. Conclusions The new PCoA-P1 score appears to provide improve predictions of stroke recurrence in patients with IVBAS.

Objective:To explore the effects of health education on the knowledge and awareness of hypertension in primary and secondary school students.Methods:Twenty seven primary and secondary schools in Emin County of Xinjiang Uygur Autonomous Region were selected in 2014 as study sites; among which 24 schools were randomly assigned as the intervention group and 3 schools were assigned as control group. According to the education methods (classroom teaching, publicity manual, hypertension class reports and the combination of the three) and the frequency of education (1, 2, 3 times per semester), the intervention group were further randomly divided into 12 subgroups with 2 schools in each group. The intervention study was carried out for 3 years.Results:A total 13 402 students were involved in the study, and there were 11 333 students in the intervention group and 2 069 students in the control group. The awareness rates of hypertension concept [41.8% (4 738/11 333) vs. 24.6% (511/2 069), χ 2=154.86, P<0.01], the adverse consequences of hypertension [85.8% (9 735/11 333) vs. 75.4% (1 561/2 069),χ 2=25.80, P<0.01], the hypertension risk factors [84.3% (9 564/11 333) vs. 72.5%(1 501/2 069), χ 2=12.83, P<0.01), and the health behaviors after hypertension [84.9% (9 629/11 333) vs. 67.7%(1 402/2 069), χ 2=187.24, P<0.01] in intervention group were all significantly higher than those in control group. The stratified analysis showed that among students in elementary school, junior high school and high school, there were significant differences in the awareness rate of adverse consequences [94.4% (2 019/2 138) vs. 81.6% (3 829/4 690), 86.2% (3 887/4 505), χ 2=199.31, P<0.01], awareness rate of risk factor [86.8% (1 857/2 138) vs.86.1% (4 038/4 690), 81.4% (3 669/4 505) , χ 2=49.96, P<0.01); and awareness rate of correct behavior [89.9% (1 923/2 138) vs. 86.1% (4 037/4 690), 81.4% (3 669/4 505) χ 2=89.77, P<0.01]. Up to 95.9% (10 868/11 333) students in the intervention group liked the hypertension health education. Conclusion:Based on the school health education curriculum, the intervention measures of hypertension health education are effective, and the awareness rate of hypertension related knowledge among senior high school students is significantly improved.

Objective:To develop a novel posterior circulation score (PCS) based on pretreatment diffusion-weighted imaging (DWI) for predicting futile recanalization (FR) of acute basilar artery occlusion (BAO) after endovascular therapy (EVT).Methods:A prospectively registered consecutive cohort of BAO patients treated with EVT in Beijing Tiantan Hospital, Capital Medical University during a six-year period was reviewed. This novel DWI-based PCS (DWI-PCS) was calculated according to the characteristics of acute infarction at four sites (pons, midbrain, thalamus and cerebellum), with a normal score of 0 point and a full score of 16 points. FR was defined as the occurrence of poor outcome (modified Rankin Scale score>3) at 90 days despite successful recanalization (modified Thrombolysis In Cerebral Infarction ≥ 2b) at final angiogram after EVT. The independent association of DWI-PCS with FR was evaluated by multivariable Logistic regression, and the predictive discrimination of DWI-PCS was measured by the area under the receiver operating characteristic (ROC) curve. Additionally, the effects of DWI-PCS on FR in different subgroups stratified by age, time window, stroke severity and etiology were explored.Results:Of 109 patients in this study, 48 (44.0%) suffered from FR. The multivariable Logistic analysis showed that DWI-PCS was significantly associated with FR (adjusted OR=1.31, 95% CI 1.07-1.62, P=0.01). The ROC curve analysis demonstrated that the area under the curve of DWI-PCS for predicting FR was 0.74 (95% CI 0.65-0.83), and the optimal cut-off value was ≥ 3 points (sensitivity 0.75, specificity 0.66, accuracy 0.70). Finally, the effects of DWI-PCS on FR were not found to be different across all subgroups ( P>0.10 for all interactions). Conclusions:The novel DWI-PCS may be a valid and reliable predictor of FR in BAO patients treated with EVT. Nevertheless, external validation with blinded outcome is still needed to confirm its performance before clinical application.

The large force applied by laparoscopic grasper during clamping operation can cause tissue damage and induce various complications. In this research, the security of graspers with different radii of curvature and teeth were evaluated by using experimental investigation, finite element simulation and tissue damage assessment method based on compression tests with rabbit large intestines models. Results showed that the most serious tissue damages appeared in areas that were in contact with the jaw edges, which were the regions of stress concentration. The increase in radii of curvature of the edges or teeth could alleviate the tissue damages. The results could provide basic data for choosing and designing noninvasive graspers.
