Objective:To evaluate the correlation between vascular hyperintensity of magnetic resonance fluid-attenuated inversion recovery (FLAIR) sequence(FVH) and related parameters of magnetic resonance perfusion weighted imaging (MR-PWI) in patients with middle cerebral artery stenosis cerebral infarction, and to explore the hemodynamic factors related to FVH and the effect of FVH on the short-term clinical prognosis of patients.Methods:A total of 116 patients with middle cerebral artery stenosis cerebral infarction in the Department of Neurology, Qingpu Branch of Zhongshan Hospital Affiliated to Fudan University from January 2020 to December 2022 were collected.According to the diagnostic criteria of FVH, they were divided into FVH (+ ) group (78 cases) and FVH(-) group (38 cases). All patients underwent magnetic resonance(MR) and MR-PWI scans.Demographic and cerebrovascular risk factors were collected, clinical neurological function of patients was assessed by national institate of health stroke scale(NIHSS) upon admission and discharge, and cognitive function of patients was assessed by mini-mental state examination (MMSE). Short-term clinical outcome was assessed using modified Rankin scale(mRS) at the 90th day after discharge.The degree of middle cerebral artery stenosis, positive or negative FVH, FVH score, hypoperfusion volume and MR-PWI related parameters, including peak time (Tmax), mean transit time (MTT), cerebral blood volume (CBV) and cerebral blood flow (CBF), were evaluated in relation to clinical symptoms.SPSS 22.0 statistical software was used for t test, Chi-square test and Pearson correlation analysis. Results:There were significant differences in hypoperfusion volume, Tmax, MTT and CBF between FVH (+ ) group and FVH(-) group( t=1.989, 3.830, 5.223, 3.911, all P<0.05). In terms of short-term clinical outcome, the improvement rate of neurological function ((8.25±6.39)%, (12.22±6.08)%) and MMSE score(25.48±1.59), (26.31±1.26) in FVH (+ ) group were significantly lower than those in FVH(-) group, and the number of patients with progressive stroke during hospitalization in FVH(+ ) group was more than that of FVH(-) group(22(28.21%), 4(10.53%)) (all P<0.05). Pearson correlation analysis showed that FVH score was positively correlated with hypoperfusion volume ( r=0.786, P<0.01) and MTT ( r=0.692, P<0.01), and negatively correlated with CBF ( r=-0.568, P<0.01), but no significant correlation with the degree of arterial stenosis ( r=0.363, P>0.05). Conclusion:FVH is closely related to the Tmax, MTT and CBF values shown in MR-PWI, and the incidence of stroke in progression and short-term adverse prognosis are more likely in FVH(+ ) group, suggesting that FVH can be used as a convenient imaging indicator to reflect the hypoperfusion status of patients with middle cerebral artery stenosis cerebral infarction, and can provide an objective basis for further individualized treatment.

Objective:To investigate the correlation between plasma fibrinogen/serum albumin ratio (FAR) and the degree of cerebral artery stenosis in patients with acute cerebral infarction (ACI).Methods:Clinical data of 189 patients with acute cerebral infarction diagnosed and treated in the Department of Neurology of the First Affiliated Hospital of Hainan Medical College from January 2021 to March 2023 were selected for retrospective analysis. Digital subtraction angiography (DSA) was improved, and they were divided into four groups according to the degree of intracranial vascular stenosis according to NASCET grading method: no stenosis group (47 cases), mild stenosis group (45 cases), moderate stenosis group (39 cases) and severe stenosis and occlusion group (58 cases). The differences of basic data, plasma fibrinogen/serum albumin ratio (FAR) and other inflammatory indicators among all groups were compared, and the correlation between FAR level and the severity of cerebral artery stenosis was analyzed. Multivariate Logistic regression was used to explore the factors influencing to cerebral artery stenosis and ROC curve was used to evaluate the diagnostic value of FAR in the degree of cerebral artery stenosis in cerebral infarction patients.Results:There were significant differences in blood neutrophil (NEU), mean platelet volume (MPV), fibrinogen (FIB), fibrinogen (FIB), albumin (ALB) and FAR among the 4 groups (statistical values were H=11.50, H=8.44, F=5.16, H=30.93, H=40.38; all P<0.05). Correlation analysis showed a positive correlation between FAR and the degree of cerebral artery stenosis ( r=0.455, P<0.05). Multivariate Logistic regression showed that FAR was an independent risk factor for the degree of cerebral artery stenosis ( OR=1.445, 95% CI=1.261-1.655, P<0.001). Conclusion:FAR is an independent risk factor for cerebral artery stenosis in patients with acute cerebral infarction (ACI), and may be a new biomarker for predicting cerebral artery stenosis.

摘要
Rhino-orbito-cerebral mucormycosis (ROCM) is an acute, rapidly progressive, and lethal opportunistic fungal disease. Due to the atypical clinical manifestations, the disease is easily misdiagnosed in the early stage. The patients with ROCM associated cerebrovascular complications generally have a high mortality rate. This article reports a 47-year-old female patient with diabetic ketoacidosis and COVID-19 admitted to Central Hospital Affiliated to Shandong First Medical University. The results of radiological examinations and cerebrospinal fluid metagenomic next-generation sequencing confirmed as Rhizopus oryzae associated ROCM. In spite of receiving amphotericin B colloidal dispersion and isavuconazole treatments, the patient died of ROCM complicated with severe cerebral infarctions and pulmonary infection. The purpose of this case report is to summarize the clinical characteristics of ROCM with cerebrovascular ischemic events and the rare condition of bilateral anterior circulation involvements, and introduce recent diagnostic and therapeutic approaches for this disease.
摘要
Objective:To summarize the incidence of cerebral venous reflux (CVR) in patients with recent small subcortical infarct (RSSI) and explore its correlation with enlarged perivascular spaces (EPVS).Methods:Patients with RSSI in the lenticulostriate artery admitted to the Department of Neurology of the First Affiliated Hospital of Zhengzhou University from January 2019 to December 2022 were included. The baseline demographic data, medical history, and laboratory results of the patients were collected. CVR was assessed by time-of-flight magnetic resonance angiography. Patients were stratified into 2 groups based on the presence (CVR group) or absence of CVR (non-CVR group), and baseline characteristics as well as laboratory test results were compared between the 2 groups. The location and number of EPVS were evaluated using a visual grading scale, with EPVS with higher scores defined as high-grade EPVS (HEPVS). Simultaneous evaluation of cerebral white matter hyperintensities and lacunar infarctions was conducted, followed by intergroup comparisons. The relationship between EPVS and CVR was studied using multiple Logistic regression analysis.Results:A total of 571 patients with RSSI in the lentiform artery area were ultimately included, including 180 females (31.5%). Their age was (59.37±12.87) years. Among them, 73 patients (12.8%) exhibited CVR based on imaging findings, so the incidence of CVR was 12.8%. In comparison between the CVR group ( n=73) and the non-CVR group ( n=498), the proportion of females [21.9% (16/73) vs 32.9% (164/498), χ 2=3.578, P=0.059] was lower and the proportion of history of smoking [38.4% (28/73) vs 27.7% (138/498), χ 2=3.499, P=0.061] was higher in the CVR group, but without statistical significance. Additionally, the history of alcohol consumption [34.2% (25/73) vs 21.7% (108/498), χ 2=5.621, P=0.018] and the proportion of patients with concomitant HEPVS in the basal ganglia area [41.1% (30/73) vs 25.3% (126/498), χ 2=7.999, P=0.005] was higher in the CVR group with statistical significance. Multiple Logistic regression analysis showed that HEPVS in the basal ganglia region remained independently associated with CVR ( OR=1.988, 95% CI 1.190-3.320, P=0.009). Conclusion:EPVS in the basal ganglia region is significantly associated with CVR in the RSSI population, suggesting that venous dysfunction may be closely related to the formation of EPVS.

ObjectiveTo investigate the changes in cerebral blood perfusion in patients with acute cerebral infarction after taking Tongnaoyin， a traditional Chinese medicine， based on head and neck computed tomography （CT） angiography （CTA） combined with brain CT perfusion imaging （CTP）. MethodA total of 240 patients with cerebral infarction of phlegm and blood stasis syndrome treated in Jiangsu Province Hospital of Traditional Chinese Medicine from March 2018 to September 2023 were randomly divided into a control group （99 cases） and a Tongnaoyin group （141 cases）. Based on the guidelines， the control group was treated with conventional treatment such as anti-aggregation， anticoagulation， lipid-lowering and plaque stabilization， brain protection， and supportive treatment. The Tongnaoyin group was treated with Tongnaoyin of 200 mL in warm conditions in the morning and evening on the basis of the control group. Both groups underwent CTA combined with CTP within 24 hours after admission， and they were reexamined by CTA and CTP in the sixth month after admission. The degree of intracranial artery stenosis was determined according to the North American Symptomatic Carotid Endarterectomy Trial （NASCET） method. The relative cerebral blood volume （rCBV）， relative cerebral blood flow （rCBF）， mean transit time （MTT）， and time to peak （TTP） of the lesion area before and after treatment were compared. The adverse outcomes of the two groups within six months after discharge were compared. ResultCompared with the group before treatment， the degree of vascular stenosis in the Tongnaoyin group was significantly reduced， and the difference was statistically significant （Z=105.369，P<0.05）. Compared with the control group after treatment， the improvement rate of vascular stenosis in the Tongnaoyin group was higher （χ2=84.179，P<0.01）， and the curative effect was better.After treatment， the rCBV and rCBF of patients in the Tongnaoyin group were significantly increased， and the difference was statistically significant （P<0.01）. MTT and TTP showed a trend of shortening， but the difference was not statistically significant. There was no statistically significant difference in rCBV， rCBF， MTT， and TTP in the control group. Compared with those in the control group after treatment， the rCBV and rCBF in the Tongnaoyin group were significantly increased， while MTT and TTP were significantly reduced （P<0.01）. After six months of discharge， the risk of poor prognosis in the Tongnaoyin group was significantly reduced compared with the control group （P<0.05）. ConclusionTongnaoyin has a good effect on improving cerebral blood perfusion in patients with acute cerebral infarction. It can be used as an effective supplement for the conventional treatment of ischemic stroke to improve clinical efficacy.

Objective:To investigate the association of white matter hyperintensities (WMHs) with long-term stroke recurrence in patients with recent subcortical small infarcts (RSSIs).Methods:Consecutive patients admitted to the Department of Neurology, Hefei Hospital Affiliated to Anhui Medical University between January 2019 and August 2022 and met the clinical and imaging manifestations of RSSIs were collected. The demographic characteristics, baseline clinical data, and MRI features were collected. Using stroke recurrence as the endpoint event, the recurrence time was recorded, and Cox regression model was used to analyze relevant factors affecting stroke recurrence in patients with RSSIs.Results:A total of 202 patients were enrolled, including 138 males (68.3%), aged 67.9±10.5 years. Seventy-seven patients (38.1%) were mild WMHs, 64 (31.7%) were moderate WMHs, and 61 (30.2%) were severe WMHs. There were statistically significant differences in age, history of stroke, hypertension, hyperlipidemia, total cholesterol, infarct thickness, and infarct distribution among different WMHs severity groups (all P<0.05). The median follow-up time was 40.5 months (interquartile range, 27.7-49.0 months), and a total of 55 patients (27.2%) had stroke recurrence (ischemic stroke 54, occipital hemorrhage 1). Recurrence rates of stroke in the mild, moderate, and severe WMHs groups were 18.2%, 31.3%, and 34.4%, respectively. Cox regression analysis showed that WMHs were an independent risk factor for stroke recurrence (compared to the mild group, the risk ratio of the severe group was 2.225, 95% confidence interval was 1.116-4.436; P=0.023). Conclusion:The risk of long-term stroke recurrence in patients with RSSI is associated with the severity of WMHs.

Objective:To investigate the predictive factors of early neurological deterioration (END) in patients with single subcortical infarction (SSI).Methods:Consecutive patients with SSI within 12 h of onset admitted to the Department of Neurology, Xuzhou Municipal Hospital Affiliated to Xuzhou Medical University from January 2016 to December 2021 were included retrospectively. The clinical and imaging data of the END and non-END groups were collected and compared. Multivariate logistic regression analysis was used to determine the independent risk factors for END. Results:A total of 1 060 patients with SSI were included, of which 268 (25.28%) developed END. There were statistically significant differences in the infarct involving internal capsule on diffusion-weighted imaging, SSI classification, maximum diameter and classification of the infarcts, and the number of infarct layers between the END group and the non-END group (all P<0.05). Multivariate logistic regression analysis showed that the infarct involved the internal capsule (odds ratio [ OR] 1.52, 95% confidence interval [ CI] 1.27-1.96; P=0.015), the maximum diameter of the infarct ( OR 1.33, 95% CI 1.12-1.42; P=0.023), proximal SSI ( OR 1.49, 95% CI 1.28-1.92; P=0.018), and the number of infarct layers (compared to 1 layer, 3 layers: OR 15.01, 95% CI 4.12-12.45, P=0.013; ≥ 4 layers: OR 15.42, 95% CI 5.67-18.43, P=0.004) were independent risk factors for END. Conclusion:Infarct involved internal capsule on diffusion-weighted imaging, larger diameter of the infarct, proximal SSI, and ≥3 layers of infarct may be predictive factors of the occurrence of END in patients with SSI.
