Objective To eval uate the lev el of knowledge of stroke in Dongying inhabitants. Methods The questionnaire for stroke contains 4 parts of general knowledge, prevention knowledge, cognition knowledge and treatment knowledge. There are 30 formal que stions and 5 split questions in it. Results The rate of a verage corrected responding for all questions is 52.8%. The level of cognition k nowledge is the lowest. In all kinds of knowledge of stroke, the group of middle -aged is better than the youth. The results of investigation from the official, the worker, the peasant and the student decreased progressively in order, and f rom educational level (high, middle and low) it decreased in the same manner. Th e respondents of those suffering from stroke is better than those without suffera nce. There is 46.2% in the respondents' scales less than 60% of the sum. Conclusion The knowledge in Dongying inhabitants concerning st roke is very poor, especially the level of cognition knowledge and treatment kno wledge. Our results suggest that public education on stroke must be wid ely carried out promptly in all the people.

To observe the changes of intelligence in cerebral infarction patients, and to explore the relationship between intelligence and brain CT feature. Methods:The intelligence was measured by WAIS-RC in 80 cerebral infarction patients.Results:The VIQ and FIQ reduced significantly in the patients with hypertension. FIQ in patients with diabetes mellitus and PIQ in patients with cerebral vesscular disease histories reduced significantly. The PIQ reduced significantly in the patients of right focus on CT. VIQ, PIQ and FIQ reduced significantly in patients of cerebral cortices involved. But the number of focus, thalamus involved and cerebral atrophy were of no significance.Conclusion:The intelligence of the cerebral infarction patients companying hypertension, diabetes mellitus and several cerebral vesscular disease histories was impaired significantly. Cerebral cortices involed was the most important factor among the features on CT relating to intelligence quotient.

Objective To explore the creation and control of measurement technique error on digital subtraction angiography (DSA). Methods The data was obtained from Advantx LCV Plus DSA system made by GE Corporation. We divided the screen into three areas, per area account for 1/3, ie, central area, middle area and outlying area. The enlargement rate or reduction rate of the target object was respectively calculated according to the different calibration, different height of the bed and different X-ray source to image distance (SID). Results The target object was enlarged gradually from the central area to the outlying area, and the lengthwise enlargement rate was more obvious than transverse. The different of target object measured by coin (diameter was 20.4 mm) with steel ball (diameter was 7.7 mm) was not significance, but the target object was underestimated significantly used the calibration by 4F catheter. When the target object was measured by the calibration in same area and same axis, the error of measurement technique was controlled rang from 1.0% to-2.5%. Conclusion This systematic investigation suggest that the screen was divided into the central area, middle area and outlying area will be beneficial to control DSA measurement error for the interventional physician. The target object was close to real size when it measured by transverse of the calibration, and the error was better controlled when the calibration was in the same area and same axis as the target object.

Objective:To investigate the predictive value of the National Institutes of Health Stroke Scale (NIHSS) score at 24 h after endovascular treatment on the outcomes in patients with acute basilar artery occlusion (ABAO).Methods:Consecutive patients with ABAO received endovascular treatment at the Department of Neurology, Shengli Oilfield Central Hospital from January 2019 to December 2020 were retrospectively included. According to the modified Rankin Scale scores at 90 days after onset, the patients were divided into a good outcome group (0-3) and a poor outcome group (4-6), as well as a survival group and a death group. The demographic and clinical data between the groups were compared respectively. Multivariate logistic regression analysis was use to identify independent influencing factors for clinical outcomes and mortality. The predictive value of postprocedural 24 h NIHSS score on the outcomes was evaluated using the receiver operating characteristic (ROC) curves. Results:A total of 35 patients with ABAO were included. Their age was 62 years (interquartile range, 56-66 years), and 28 patients were males (80%); 19 (54.3%) had a good outcome, 16 (45.7%) had a poor outcome, and 7 (20.0%) died. Univariate analysis showed that there were statistically significant differences in hypertension, low-density lipoprotein cholesterol, fasting blood glucose, collateral circulation grading, vascular recanalization, and postprocedural 24 h NIHSS scores between the good outcome group and the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that the postprocedural 24 h NIHSS score was independently correlated with the poor outcome (odds ratio 1.131, 95% confidence interval 1.017-1.258; P=0.023). Multivariate analysis did not find the independent influencing factors for death. ROC curve analysis showed that the area under the curve of the postprocedural 24 h NIHSS score for predicting poor outcome was 0.814 (95% confidence interval 0.668-0.960; P=0.011). The optimal cutoff value was 19 points, and the corresponding sensitivity and specificity were 85.7% and 71.4% respectively. Conclusions:In patients with ABAO receiving endovascular treatment, the postprocedural 24 h NIHSS score has good predictive value for poor outcomes at 90 d after procedure.

Objective To compare the clinical effects of catheter-directed thrombolytic therapy for acute superior mesenteric vein thrombus (SMVT) between via superior mesenteric vein (SMV) route and via superior mesenteric artery (SMA) route. Methods The clinical data of 32 patients with acute SMVT, who were treated with catheter-directed thrombolytic therapy at the Central Hospital of Shengli Oil Field, were retrospectively analyzed. Among the 32 patients, percutaneous transhepatic catheter-directed thrombolytic therapy via SMV route was performed in 23 (SMV group), and percutaneous transhepatic catheter-directed thrombolytic therapy via SMA route was carried out in 9 (SMA group). Results After the treatment, the clinical symptoms were significantly improved in 28 patients, including 22 of SMV group (95.7%) and 6 of SMA group (66.7%). CT angiography showed that the blood flow became almost complete patency in 17 patients of SMV group (73.9%) and in only 3 patients of SMA group (33.3%). Both the thrombolysis procedure time and X-ray exposure time of SMV group were obviously longer than those of SMA group. Conclusion Both via SMV and via SMA catheter-directed thrombolytic therapies are effective treatment for acute SMV thrombosis. The former is more effective, while the manipulation of the latter is technically simpler.

Cerebrovascular diseases and cardiovascular diseases are among the top causes of death worldwide. In recent years, the concept of "brain-heart co-treatment" has gradually gained popularity. Cerebrovascular and cardiovascular diseases have similar pathological foundations, pathogenesis, comorbidities, and treatment methods. However, there is currently limited research on whether the two have a chronological order of the first onset and which is the index event of the other. However, elucidating the above issues is of great significance for the secondary prevention of cardiocerebrovascular diseases. This article reviews the correlation of onset time and influencing factors for ischemic stroke and myocardial infarction.

Objective:To investigate the predictive value of fasting blood glucose on clinical outcome after intravenous thrombolysis in patients with severe acute ischemic stroke (AIS).Methods:From January 2016 to November 2020, consecutive patients with severe AIS receiving intravenous thrombolysis in the Department of Neurology, Shengli Oilfield Central Hospital were enrolled retrospectively. Severe AIS was defined as the baseline National Institutes of Health Stroke Scale (NIHSS) score ≥15. The primary endpoint was the clinical outcome evaluated according to the modified Rankin Scale at 90 d after onset. 0-2 was defined as a good outcome and a score of >2 were defined as a poor outcome. The secondary endpoint events were any intracranial hemorrhage and symptomatic intracranial hemorrhage (sICH). Intracranial hemorrhage was defined as any local or distant parenchymal hemorrhage shown by craniocerebral imaging during the hospitalization. sICH was defined as any intracranial hemorrhage and the NIHSS score increased by ≥4 within 7 d after treatment. Univariate and multivariate logistic regression analysis were used to determine the independent influencing factors of various endpoint events. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of fasting blood glucose levels for endpoint events. Results:A total of 113 patients with severe AIS treated with intravenous thrombolysis were included, and 73 (64.6%) had a poor outcome; 29 (25.7%) had intracranial hemorrhage, of which 10 (8.8%) were sICH. Multivariate analysis showed that fasting blood glucose was the independent risk factors for poor outcome (odds ratio [ OR] 1.451, 95% confidence interval [ CI] 1.053-2.000; P=0.023) and sICH ( OR 1.235, 95% CI 1.013-1.504; P=0.036). The ROC curve analysis showed that the area under the curve of fasting blood glucose predicting poor clinical outcome at 90 d after onset was 0.731 (95% CI 0.637-0.824), the optimal cut-off value was 6.25 mmol/L, and the corresponding sensitivity and specificity were 63.0% and 82.5% respectively. The area under the curve of fasting blood glucose predicting sICH was 0.728 (95% CI 0.577-0.878), the optimal cut-off value was 7.98 mmol/L, and the corresponding sensitivity and specificity were 70.0% and 77.7% respectively. Conclusion:Fasting blood glucose is an independent predictor of sICH and poor outcome at 90 d after onset in patients with severe AIS receiving intravenous thrombolysis.

Objective To investigate the effectiveness and safety in patients with largeartery occlusive acute cerebral infarction who received multi-interventional modes mainly with mechanical thrombectomy and its related factors affecting prognosis. Methods The clinical data of 56 patients with large artery occlusive acute cerebral infarction were analyzed retrospectively. The clinical characteristics (gender,age,and underlying diseases),timing of treatment (time from ictus to puncture,time from puncture to recanalization), multi-interventional mode therapies (intra-arterial thrombolysis,thrombectomy,balloon dilation,and stenting, etc. ),and distribution of offending vessels were observed. The modified Thrombolysis in Cerebral Ischemia Scale (mTICI)grade was used to evaluate revascularization. The National Institute of Health Stroke Scale (NIHSS)score was used to observe the neurological function at 24 h before and after procedures. The modified Rankin scale (mRS)was used to evaluate the prognosis at 3 months after procedure. The safety of the treatment was evaluated with operative complications (mainly symptomatic intracranial hemorrhage)and mortality. The patients were divided into either a good prognosis group (n = 34;mRS≤2)or a poor prognosis group (n =22;mRS≥3)according to the prognosis at 3 months after procedure. They were analyzed with univariate analysis. The factors influencing the prognosis were further analyzed with multivariate logistic regression analysis. Results (1)The recanalization rate in 56 patients was 78. 6%(n = 44),in which basilar artery was the highest,reaching 93. 8% (15 / 16),middle cerebral artery was 87. 0% (20 / 23). The NIHSS score at 24 hours was 10 ± 7,it was lower than 16 ± 6 on admission. There was significant difference (t =6. 401,P <0. 01). At 3 months,34 patients (60. 7%)had good prognosis,4 (7. 1%)died,and 8 (14. 3%) had symptomatic intracranial hemorrhage. (2)Multiple factor analysis showed that the high level of recanalization was a protective factor for good prognosis (OR,0. 465,95% CI 0. 267 -0. 809,P =0. 007). Diabetes was an independent risk factor for poor prognosis (OR,5. 535,95% CI 1. 101 -27. 835, P = 0. 038). Conclusion Acute large artery occlusive cerebral infarction treated with the intra-arterial multi-interventional modes may quickly and effectively restore intracranial blood flow. It has the characteris-tics of high recanalization rate and good prognosis,and the higher the level of recanalization,the better the prognosis. Diabetes is an independent risk factor for poor prognosis.

Objective To evaluate the effect of contrast medium on the renal function in patients with cerebrovascular disease accompanied by diabetes mellitus after receiving neuro - interventional therapy. Methods The clinical data of a total of 108 patients with cerebrovascular disease complicated by diabetes mellitus type 2, who were treated with neuro - interventional therapy during the period from March 2013 to March 2016, were retrospectively analyzed. The contrast dose used in interventional procedures was less than 250ml in each patient. The preoperative and 24 h -postoperative serum creatinine (sCr), serum cystatin C (Cys C) levels were determined, and based on the modification of dietary renal disease (MDRD) equation and Larsson equation the estimated glomerular filtration rates (eGFR) were separately calculated. Results Compared with preoperative values, the 24 h - postoperative mean sCr and Cys C levels were increased significantly (P=0. 001, P=0. 015 respectively), while the average eGFR rates were remarkably decreased (P＜ 0. 000 1 by using MDRD equation, and P=0. 021 by using Larsson equation). No kidney damage that needed to be treated occurred in all patients. Conclusion The contrast dose used in neuro - interventional procedures can cause decline of renal function in patients with type 2 diabetes mellitus. The combined determination of sCr and Cys C levels is helpful for the detection of contrast - induced changes in renal function as early as possible. The use of conventional dose of contrast agent in neuro - interventional procedures is safe for patients with type 2 diabetes mellitus. (J Intervent Radiol, 2018, 27:277-280)
