Abstract
This case report details the sudden onset of an ischemic stroke in a man in his late 20s, attributed to elevated homocysteine levels. Despite his young age, the patient exhibited increased homocysteine levels, a recognized stroke risk factor. This report underscores the critical importance of recognizing hyperhomocysteinemia as a potential underlying cause of strokes, even in younger age groups. Following ischemic stroke-directed treatment along with the addition of folic acid, vitamin B6, vitamin B12, and methylcobalamin, the patient's condition improved, leading to discharge with normalized homocysteine levels. Highlighting the significance of identifying this risk factor is particularly essential in regions like Pakistan, where a notably high prevalence of hyperhomocysteinemia has been reported. This case serves as a poignant reminder of the need for comprehensive stroke evaluations, urging medical practitioners to consider homocysteine as a potential contributing factor, even when dealing with young and healthy patients.

Abstract
Eagle's syndrome is characterised by elongation of the styloid process. The elongated styloid process can cause symptoms like dysphagia, facial or neck pain, syncope, visual changes, etc. In severe cases, it may cause a rupture or dissection of the carotid artery, which can lead to intracranial thrombo-embolism and ischemic stroke. We report a case of a 57-year-old male presenting with dysarthria and mild left-sided body weakness. An initial non-contrast computed tomography (CT) scan showed a possible right internal carotid artery thrombus. He developed worsening left-sided weakness and gaze palsy one day after the admission. Repeated CT brain and intracranial angiography were arranged, which showed significant oedema with mass effect and right internal carotid artery dissection with thrombus. He underwent decompressive craniectomy. An enlarged styloid process measuring 4.53 cm in close proximity to the cervical vasculature was also noted. He was not deemed an appropriate candidate for styloidectomy. Due to residual left-sided weakness, he had to take early retirement. He underwent extensive rehabilitation and was able to mobilize with the help of a quad stick after a period of nine months. At the five-year follow-up, there were no characteristic symptoms of Eagle's syndrome and he was mobilizing without support.

Abstract
Tuberculosis is an infectious disease with broad pulmonary and extrapulmonary clinical manifestations. Central nervous system tuberculosis (CNS-TB) is a complex extrapulmonary infection known for its diverse clinical features including meningitis, tuberculoma, and spinal arachnoiditis. Particularly, tuberculosis meningitis can further lead to complications such as ischemic stroke. This article presents a challenging case of a 35-year-old male patient initially diagnosed with epididymo-orchitis, followed by viral-like central nervous system symptoms, ultimately complicated by tuberculosis meningitis and basal ganglia ischemic stroke. This case presentation underscores the diagnostic complexities associated with CNS-TB and emphasizes on the critical need for heightened awareness of the wide-ranging clinical presentations that can potentially delay early disease recognition and management.

Abstract
Reversible cerebral vasoconstriction syndrome (RCVS) is a rare neurological condition that classically presents with recurrent, thunderclap headaches and radiographic findings of multifocal narrowing of cerebral vasculature. Complications of RCVS may include ischemic or hemorrhagic strokes. Sympathomimetic agents including cannabinoids have been associated as precipitants in many cases. RCVS is classically considered to be reversible, although cases of recurrent RCVS have been described in the literature. In this report, we describe two cases of recurrent RCVS, which were precipitated by recurrent exposures to inciting agents. The first patient was found to have a history of repeated exposure to tetrahydrocannabinol (THC) and suffered from recurrent multifocal ischemic strokes with evidence of persistent multifocal narrowing of cerebral vasculature by cerebral arteriography. The second case describes a patient with a history of use of ashwagandha, medical marijuana, and serotonin-norepinephrine reuptake inhibitors (SNRIs) who experienced multiple intracranial hemorrhages with radiographic evidence of multifocal narrowing of cerebral vessels as well.

Abstract
Background Previous studies found that increasing vegetable intake benefits are reduced after adjustment for socioeconomic factors. Using genetic variation as an instrumental variable for vegetable intake and socioeconomic status, we investigated the relationship between vegetable intake and ischemic cardio-cerebral vascular diseases and focused on whether socioeconomic status was a possible confounder. Methods From three independent genome-wide association studies, we extracted instrumental variables reflecting raw and cooked vegetable intake, which were used to perform Mendelian randomization analysis. To evaluate the effects of socioeconomic factors on vegetable intake, univariate and multivariate Mendelian randomization analyses were performed using single nucleotide polymorphisms representing education attainment and household income reported in the literature. We also performed outlier assessment and a series of sensitivity analyses to confirm the results. Results Genetically predicted raw and cooked vegetable intake were not associated with any ischemic cardio-cerebral vascular diseases and lipid components after Bonferroni correction. Univariate Mendelian randomized analysis revealed that raw vegetable intake was positively correlated with education attainment (β = 0.04, p = 0.029) and household income (β = 0.07, p < 0.001). Multivariate Mendelian randomized model showed a positive correlation between household income and raw vegetable intake (β = 0.06, p = 0.004). Socioeconomic status was closely associated with eating habits and lifestyle related to the risk of cardiovascular diseases. Conclusion Genetically determined raw and cooked vegetable intake was not associated with significant benefits in terms of ischemic cardio-cerebral vascular diseases while genetically determined socioeconomic status may have an impact on vegetable intake. Socioeconomic status, which was closely associated with other eating habits and lifestyle, may affect the association between vegetable intake and ischemic cardio-cerebral vascular diseases.

Abstract
Cocaine overdose remains a significant public health concern worldwide, with potentially life-threatening consequences. The range of presentation can vary from mild autonomic hyperactivity to severe vasoconstriction, causing multiorgan ischemia and even death. In cases of high-dose intoxication, the presentation can be atypical. In this case report, we present a compelling case of a patient who initially presented with cardiac arrest and atypical signs. The patient made a remarkable recovery and returned almost to her baseline. This case provides valuable prognostic insight into the outcomes of severe multiorgan failure resulting from cocaine toxicity.

Abstract
Epidemiological studies have shown that people having hyperuricemia are at increased risk of ischemic cerebrovascular disease. This research aimed to study the relation of ischemic cerebrovascular disease with benzbromarone use among persons with gout-related disorders. This was a retrospective cohort design utilizing a 2003 to 2015 national health insurance database in Taiwan. Subjects aged 20 to 99 years who already had suffered from gout-related disorders were included as eligible subjects. Eligible persons who had the benzbromarone prescription alone were selected into the benzbromarone group. Sex-matched and age-matched eligible persons who never used any urate-lowering agents were selected into the control group. An index date was set as a date of benzbromarone being prescribed. The end-point was defined as ischemic cerebrovascular disease being newly diagnosed. A hazard ratio was applied to measure the association strength between benzbromarone use and ischemic cerebrovascular disease. Totally, there were 13,398 persons in the benzbromarone group and 13,398 persons in the control group. The incidence rate of ischemic cerebrovascular disease seemed to be modestly higher in the benzbromarone group than the control group, but it did not achieve statistical significance (0.78 vs 0.75 every 100 person-years, incidence rate ratio = 1.05, 95% confidence interval = 0.94-1.16). A crude hazard ratio of ischemic cerebrovascular disease showed 1.05 in the benzbromarone group (95% confidence interval = 0.94-1.17, P = .373) comparing with the control group. No significant association can be detected between benzbromarone use and the probability of ischemic cerebrovascular disease among persons with gout-related disorders. We think that reduction of the serum uric acid by use of benzbromarone could not be related to the probability of ischemic cerebrovascular disease. Further research is suggested to clarify this issue.

Abstract
This study intended to evaluate the efficacy and safety of single Hirudo prescriptions in the treatment of ischemic cerebrovascular disease(ICVD) by frequency network Meta-analysis and traditional Meta-analysis. CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library databases were searched to collect the randomized controlled trial(RCT) of single Hirudo prescriptions for ICVD from the inception of the databases to May 2022. The quality of the included literature was evaluated by Cochrane risk of bias tool. Finally, 54 RCTs and 3 single Hirudo prescriptions were included. Statistical analysis was conducted by RevMan 5.3 and Stata SE 15. Network Meta-analysis showed that in terms of the clinical effective rate, the surface under the cumulative ranking curve(SUCRA) of intervention measures was as follows: Huoxue Tongmai Capsules+conventional treatment>Maixuekang Capsules+conventional treatment>Naoxuekang Capsules+conventional treatment>conventional treatment. Traditional Meta-analysis revealed that in terms of the safety of ICVD treatment, Maixuekang Capsules+conventional treatment had higher safety than conventional treatment alone. According to the network Meta-analysis and traditional Meta-analysis, it was found that conventional treatment combined with single Hirudo prescriptions improved the clinical efficacy of ICVD patients, and compared with that of conventional treatment alone, the incidence of adverse reactions of combined treatment was low and the safety was high. However, the methodological quality of the articles included in this study was generally low and there were large differences in the number of articles on the three combined medication. Therefore, the conclusion of this study needed to be confirmed by subsequent RCT.

Abstract
Background It is reported that insulin resistance widely exists in non-diabetic patients with a recent history of transient ischemic attack (TIA) or ischemic stroke. There is currently strong evidence to prove the bidirectional effect of glucose metabolism disorders and stroke events. Therefore, it is necessary to retrospectively tease out the current status, hotspots, and frontiers of insulin resistance and ischemic cerebrovascular disease through CiteSpace. Materials and methods We searched the Web of Science (WOS) for studies related to insulin resistance and ischemic cerebrovascular disease from 1999 to April 2022, then downloaded the data into CiteSpace to generate a knowledge visualization map. Results A total of 1,500 publications relevant to insulin resistance and ischemic cerebrovascular disease were retrieved. The USA had the most articles on this topic, followed by PEOPLES R CHINA and JAPAN. WALTER N KERNAN was the most prolific author, whose research mainly focused on insulin resistance intervention after stroke (IRIS) trial. The most common keywords were myocardial ischemia, metabolic syndrome, ischemic stroke, cerebral ischemia, association, oxidative stress, inflammation, and adipose tissue. Major ongoing research trends include three aspects: (1) the association between insulin resistance and ischemic cerebrovascular disease in non-diabetic patients, (2) the intrinsic pathological mechanism between insulin resistance and ischemic cerebrovascular disease, and (3) early intervention of insulin resistance to improve the prognosis of stroke. Conclusion The results of this bibliometric study provide the current status and trends of clinical research publications in the field of insulin resistance and ischemic cerebrovascular disease. Insulin resistance is strongly associated with the occurrence of ischemic stroke, early neurological deterioration in stroke patients, post-stroke depression, and cerebral small vessel disease. Early treatment of insulin resistance can be an effective way to prevent the onset of ischemic stroke and improve stroke prognosis. This study may help researchers to identify hot topics and explore new research directions.

Abstract
Ischemic cardiac or cerebrovascular disease (ICCD) survivors represent a subpopulation with a high cancer risk. Antiplatelet medications, such as aspirin, remain a fundamental therapy for the secondary prevention of ischemic attack in these patients. We conducted a population-based cohort study to investigate the association of long-term low-dose aspirin use with the risk of primary cancer in ICCD survivors. Patients aged ≥20 years with newly diagnosed ICCD (n = 98,519) between January 2000 and December 2013 were identified from the Taiwan National Health Insurance Research Database. The aspirin user and nonuser groups (each n = 24,030) were propensity-matched (1:1) for age, sex, comorbidities, prior medications, ICCD diagnosis year, and year of index dates. The incidence rate of primary cancer was significantly lower in the user group (6.49/1000 person-years) than in the nonuser group (14.04/1000 person-years). Multivariate Cox regression analysis indicated that aspirin use was an independent factor associated with a reduced risk of primary cancer (aHR (95% confidence interval) = 0.42 (0.38−0.45)) after adjustment. Kaplan−Meier curve analysis revealed that the cumulative incidence rate of primary cancer was significantly lower (p < 0.0001) in the user group than in the nonuser group over the 14-year follow-up period. Subgroup analyses demonstrated that this anticancer effect increased with duration of treatment and with similar estimates in women and men. In addition, aspirin use was associated with a reduced risk for seven out of the ten most common cancers in Taiwan. These findings suggest the anticancer effect of aspirin in ICCD survivors and provide information for assessing the benefit-to-risk profile of aspirin as an antiplatelet medication in these patients.

Abstract
Spinal cord infarction is a very rare event with a wide variety of symptoms at presentation. We describe the case of a 39-year-old man who presented to the emergency department with atypical chest pain. The initial investigations were non-diagnostic, and the patient was admitted for surveillance. On the second day of admission, he developed neurologic deficits; a second computed tomography showed a medullary infarction at levels C5-T2. Dual antiplatelet therapy was initiated. An extensive study on the underlying etiology was performed. It was considered to be an idiopathic event. The patient was discharged to a rehabilitation center for bladder training and motor training due to quadriplegia level D on Asia Impairment Scale with a C6 neurological level with left predominance and a hand grip deficit that disabled him to grab objects. This case report describes a rare event with a biphasic ictus at presentation. It highlights the difficulty in managing this pathology because of limited clinical data.

Abstract
OBJECTIVE The study aimed to analyze the relationship between expression levels of chemerin, oxidized low density lipoprotein (ox-LDL), matrix metalloproteinase 9 (MMP-9) and pregnancy associated plasma protein A (PAPP-A) in ischemic cerebrovascular disease (ICVD) patients and the relationship between the mentioned indicators and the degree of neurological impairment. METHODS From January 2020 to February 2021, a total of 328 cases of ICVD patients were admitted to our hospital, and 240 cases of healthy people (control group) were prospectively recruited into this study. The 328 patients were divided into 2 ischemic subtypes, with 233 cases as acute cerebral infarction (ACI) and 95 cases as transient ischemic attack (TIA). Laboratory tests were compared among the groups. Spearman rank correlation was used to analyze the correlation between chemerin, ox-LDL, MMP-9, PAPP-A levels and neurological deficit. Unconditional logisitic regression was used to analyze the risk factors for neurological deficits. RESULTS The high density lipoprotein cholesterol (HDL-C), fasting plasma glucose (FPG), chemerin, ox-LDL, MMP-9, and PPAP-A levels in the ACI group were significantly higher than those in the TIA group and control group (p < 0.05, respectively), while the levels of the mentioned indicators in the TIA group were significantly higher than those in control group (p < 0.05, respectively). The levels of the given indicators decreased successively in the severe, moderate, and mild neurological deficits population and control group, with statistical difference. Spearman rank correlation analysis showed that chemerin, ox-LDL, MMP-9, and PPAP-A levels were positively correlated with the degree of neurological deficit in ICVD patients. Unconditional logistic regression analysis showed that chemerin, ox-LDL, MMP-9, and PPAP-A were the independent risk factors for neurological deficit in patients with ICVD. CONCLUSION LDL-C, FPG, chemerin, ox-LDL, MMP-9, and PPAP-A were highly expressed in ACI and neurological deficit patients. Chemerin, ox-LDL, MMP-9, and PPAP-A may be the independent risk factors for neurological deficit in patients with ICVD.

Abstract
Central alveolar hypoventilation (CAH) is a rarely encountered pathology characterized by decreased ventilation due to the loss of autonomic control. Most cases present at birth, as it can be a rare genetic disorder, but we aim to show that it can occur as an acquired condition too. We present a case of a 65-year-old man who developed CAH as a sequela of an ischemic stroke and discuss possible pathophysiology. Increasing awareness and an early detection of this condition can have a significant effect on morbidity and mortality of patients.

Abstract
Introduction Approximately 5-10% of strokes occur in adults of less than 45 years of age. The rising prevalence of stroke risk factors may increase stroke rates in young adults (YA). We aimed to compare risk factors and outcomes of acute ischemic stroke (AIS) among YA. Methods Adult hospitalizations for AIS and concurrent risk factors were found in the Nationwide Inpatient Sample database. Weighted analysis using chi-square and multivariable survey logistic regression was performed to evaluate AIS-related outcomes and risk factors among YA (18-45 years) and older patients. Results A total of 4,224,924 AIS hospitalizations were identified from 2003 to 2014, out of which 198,378 (4.7%) were YA. Prevalence trend of YA with AIS showed incremental pattern over time (2003: 4.36% to 2014: 4.7%; pTrend<0.0001). In regression analysis, the risk factors associated with AIS in YA were obesity (adjusted odds ratio {aOR}: 2.26; p<0.0001), drug abuse (aOR: 2.56; p<0.0001), history of smoking (aOR: 1.20; p<0.0001), infective endocarditis (aOR: 2.08; p<0.0001), cardiomyopathy (aOR: 2.11; p<0.0001), rheumatic fever (aOR: 4.27; p=0.0014), atrial septal disease (aOR: 2.46; p<0.0001), ventricular septal disease (aOR: 4.99; p<0.0001), HIV infection (aOR: 4.36; p<0.0001), brain tumors (aOR: 7.89; p<0.0001), epilepsy (aOR: 1.43; p<0.0001), end stage renal disease (aOR: 2.19; p<0.0001), systemic lupus erythematous (aOR: 3.76; p<0.0001), polymyositis (aOR: 2.72; p=0.0105), ankylosis spondylosis (aOR: 2.42; p=0.0082), hypercoagulable state (aOR: 4.03; p<0.0001), polyarteritis nodosa (aOR: 5.65; p=0.0004), and fibromuscular dysplasia (aOR: 2.83; p<0.0001). Conclusion There is an increasing trend in AIS prevalence over time among YA. Both traditional and non-traditional risk factors suggest that greater awareness is needed, with prevention strategies for AIS among young adults.

Abstract
Background: Cognitive impairment has become an important problem in ischemic cerebrovascular disorder survivors as disease related deaths have been significantly reduced. Aerobic exercise, the most prevalent mode of physical activity, positively contributes to cognition in both healthy population and people with cognitive impairment. However, studies on its associations with cognitive gains in patients with ischemic cerebrovascular disease showed mixed findings. Objective: To explore the cognitive effects of aerobic exercise on ischemic cerebrovascular disorder survivors and investigate the possible moderators on exercise benefits. Method: Randomized controlled trials investigating the effects of sole aerobic exercise on cognitive function in population with ischemic intracranial vascular disorder compared to any control group who did not receive the intervention were enrolled in this systematic review and meta-analysis. Four online database (Pubmed, Cochrane Library, Embase, and Web of Science) were searched. Results: The initial search returned 1,522 citations and ultimately 11 studies were included in the systematic review. Analysis of seven studies showed the beneficial but not statistically significant impact of aerobic exercise on global cognitive function (0.13; 95% Cl −0.09 to 0.35; p = 0.25). Participants already with cognitive impairment benefited more from this intervention (0.31; 95% Cl 0.07–0.55; p = 0.01) and moderate intensity might be the optimal choice (0.34; 95% Cl −0.01 to 0.69; p = 0.06). The program duration and initiation time after stroke occurrence did not predict better cognitive outcome. Aerobic exercise was not associated with improvement of processing speed and executive function, the two subdomains of cognitive function. Conclusions: Aerobic exercise may contribute to cognitive gains in survivors of ischemic cerebrovascular disorder, especially for population already with cognitive decline. Our findings suggest that the adoption of moderate intensity aerobic exercise might improve cognition in such population.

Abstract
The present study aimed to investigate the efficacy of neurointervention combined with intravenous thrombolysis in the treatment of ischemic cerebrovascular disease (ICD) and its influence on the neurological function and prognosis of patients. A total of 119 patients with ICD admitted to Xinxiang Central Hospital (Xinxiang, China) from May 2013 to September 2015 were selected. Among them, 65 patients were enrolled in the control group and treated with intravenous thrombolysis, whereas the other 54 patients were enrolled in the observation group and were treated with intravenous thrombolysis combined with neurointervention. The National Institute of Health Stroke Scale (NIHSS) system was used to evaluate the neurological function of patients after treatment. Kaplan-Meier survival curve analysis was carried out to assess the survival of patients. The total effective rate, complications, vascular recanalization and the hospitalization time after treatment were compared between the two groups. The NIHSS scores at 1, 3 and 6 months after treatment were statistically lower in the observation group than those in the control group (P<0.05). The total effective rate and total vascular recanalization in the observation group were higher than those of the control group (P<0.05). The incidence of complications in the observation group was statistically lower than that in the control group (P<0.05). In conclusion, neurointervention combined with intravenous thrombolysis can not only effectively improve the diseased blood vessels of patients and restore the damaged nerve function, but also reduce the incidence of complications. Moreover, neurointervention combined with intravenous thrombolysis is safe and can ensure a better quality of life of patients.

Abstract
Objective: To make comparative studies on the effects of different doses of atorvastatin combined with aspirin on inflammatory cytokines, blood lipids, blood glucose, other biochemical indexes and carotid plaques in patients with ischemic cerebrovascular disease (ICVD) and carotid plaques. Method: One hundred and twenty patients with ICVD and carotid plaques admitted by Renmin Hospital, Hubei University of Medicine Hospital from December 2016 to December 2017 were selected and randomly divided into experimental group and control group, 60 cases in each group. Patients in the control group was asked to orally take standard dose of atorvastatin (20 mg/d) combined with aspirin enteric-coated tablets (100 mg/d). Patients in the experimental group was asked to orally take high-dose atorvastatin (40 mg/d) combined with the same amount of aspirin enteric-coated tablets. Patients in two groups were treated for 6 months averagely. The levels of inflammatory factors, changes in blood biochemical parameters and carotid plaque degrees of patients in two groups before and after treatment were inspected and compared. Results: The levels of serum high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor (TNF-a), interleukin-6 (IL-6) and homocysteine (Hcy) in patients of the experimental group after treatment were higher than those in the control group, difference with statistical significance (p < .05). The total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) in patients of the experimental group after treatment were lower than those in the control group and before treatment. The high-density lipoprotein cholesterol (HDL-C) was higher than that of the control group and before treatment, the levels of fasting blood glucose (FBS) and glycosylated hemoglobin (HbAIc) in patients of the experimental group significantly increased compared to those before treatment, difference with statistical significance (p < .05). There was no significant change in the control group. The carotid intima-media thickness (IMT) and plaque area in patients of the experimental group were lower than those in the control group and before treatment, difference with statistical significance (p < .05). Conclusion: High-dose atorvastatin combined with aspirin for treatment of patients with ICVD can effectively reduce inflammatory inflammatory cytokine levels in serum and reduce IMT and carotid plaque area. With more obvious effect than lower dose of atorvastatin combined with aspirin, it is easy to cause blood glucose abnormality. So, it is necessary to pay attention to monitoring blood sugar during medication period.

Abstract
Only a few cases regarding postobstructive pulmonary edema following laryngospasm in older patients aged more than 60 years have been reported; however, acute pulmonary edema or pulmonary hemorrhage would be more deadly to elderly patients who have cerebrovascular disease than young healthy adults. After review of the literature, we report an unusual case of a 67-year-old man with ischemic cerebrovascular disease, who underwent carotid angioplasty and stenting and experienced severe pulmonary edema and hemorrhage secondary to laryngospasm after general anesthesia with laryngeal mask airway. The patient required positive-pressure ventilation, supportive treatment, and active cerebroprotection in the intensive care setting for 3 days before the edema resolved, and subsequently made a complete recovery without new onset of neurologic sequelae. The possible pathophysiological mechanisms, precaution, and preventative strategy of postobstructive pulmonary edema in older patients are discussed.

Abstract
The protective effect of dexmedetomidine on cognitive dysfunction and decreased attention network function of patients with ischemic cerebrovascular disease after stenting was investigated. Fifty-eight patients with ischemic cerebrovascular disease undergoing stenting in Guizhou Provincial People's Hospital were selected and randomly divided into control group (n=29) and dexmedetomidine group (n=29). The dexmedetomidine group was treated with dexmedetomidine before induced anesthesia, while the control group was given the same dose of normal saline; and the normal volunteers of the same age were selected as the normal group (n=29). At 3 days after operation, the levels of serum S100B and nerve growth factor (NGF) in each group were detected using the enzyme-linked immunosorbent assay, and the level of brain-derived neurotrophic factor (BDNF) was detected via western blotting. Montreal cognitive assessment (MoCA) and attention network test (ANT) were performed. Moreover, the cognitive function and attention network function, and the effects of dexmedetomidine on cognitive function and attention network function were evaluated. The concentrations of serum S100B and NGF in dexmedetomidine group was lower than those in control group (P<0.01). The results of western blotting showed that the levels of serum BDNF in control group and dexmedetomidine group were significantly lower than that in normal group (P<0.01), and it was higher in dexmedetomidine group than that in control group (P<0.01). Besides, both MoCA and ANT results revealed that the visual space and executive function scores, attention scores, delayed memory scores, targeted network efficiency and executive control network efficiency in dexmedetomidine group were obviously higher than those in control group (P<0.01). The cognitive function and attention network function of patients with ischemic cerebrovascular disease have a certain degree of damage, and the preoperative administration of dexmedetomidine can effectively improve the patient's cognitive dysfunction and attention network function after operation.

Abstract
Background and Objectives: Limited research focuses on the risk of ischemic cerebrovascular disease associated with use of dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) in patients with type 2 diabetes mellitus in Taiwan. This study aimed to investigate the association between DPP-4 inhibitors use and the first episode of ischemic cerebrovascular disease. Methods: We designed a case-control study using the database of the Taiwan National Health Insurance Program. There were 1999 type 2 diabetic subjects aged 20-84 years with the first episode of ischemic cerebrovascular disease from 2000 to 2013 as the cases, and 7996 sex- and age-matched, randomly selected type 2 diabetic subjects aged 20-84 years without any type of cerebrovascular diseases as the matched controls. We estimated the odds ratio (OR) and 95% confidence interval (CI) of ischemic cerebrovascular disease associated with cumulative duration of DPP-4 inhibitors use by the multivariable logistic regression model. Results: After adjustment for confounding variables, the adjusted OR of ischemic cerebrovascular disease was 0.96 (95% CI 0.95, 0.97) in subjects with ever use of DPP-4 inhibitors as increase in use duration for every 1 month, compared with never use. The sub-analysis disclosed that the adjusted ORs of ischemic cerebrovascular disease were 1.57 (95% CI 1.36, 1.80) for subjects with cumulative duration of DPP-4 inhibitors use <1 year, and 0.70 (95% CI 0.57, 0.87) for subjects with cumulative duration of DPP-4 inhibitors use ≥1 year, compared with never use. Conclusion: Our findings suggest that DPP-4 inhibitors use correlates with relative risk reduction of the first episode of ischemic cerebrovascular disease in type 2 diabetic patients in a duration-dependent response. The beneficial effect will be marked when DPP-4 inhibitors use is ≥1 year.

Abstract
To analyze the clinical drug use characteristics of Shenxiong glucose injection in the treatment of ischemic cerebrovascular disease. From hospital information system (HIS) of 19 hospitals over China, the basic information of patients with Shenxiong glucose injection for ischemic cerebrovascular disease, traditional Chinese medicine and Western medicine diagnosis information, order information, and laboratory examination information were extracted. Then Apriori algorithm was used to construct the model, and the association analysis was performed by using Clementine 12 to analyze the clinical drug use characteristics of Shenxiong glucose injection in the real world. A total of 411 kinds of Western medicines and 110 kinds of traditional Chinese medicines were included in 784 cases of drug combination. In the drug combination, aspirin had the highest frequency in Western medicine, which was used in 515 cases (65.69%); Ginkgo biloba extract had the highest frequency in Chinese medicine, which was used in 121 cases (15.43%). Atorvastatin+aspirin (association rules of 10.15%) was the most common Western medicine pairs; atorvastatin+clopidogrel+aspirin (association support 5.56%) was the most common triple Western medicine therapy, often combined with antibiotics and blood stasis drugs in use. Results showed that Shenxiong glucose injection was often combined with antiplatelet drugs and blood stasis drugs in the treatment of ischemic cerebrovascular disease clinically, contributing to the enhancement of platelet aggregation and blood stasis. The incompatibility of combined application of drugs shall be noted to ensure the clinical medication safety and efficacy of the combined drug use.

Abstract
Background and Objectives: There are inconsistent results about the association between ischemic cerebrovascular disease and tamoxifen use in women with breast cancer. The study aimed to evaluate the association between the risk of ischemic cerebrovascular disease and tamoxifen use in older women with breast cancer in Taiwan. Methods: We designed a retrospective, nationwide, case-control study using the database of the Taiwan National Health Insurance Program. A total of 800 female subjects with breast cancer aged ≥65 years with the first episode of ischemic cerebrovascular disease from 2000 to 2011 were identified as the cases. Additionally, 2,876 female subjects with breast cancer aged ≥65 years without any type of cerebrovascular diseases were selected as the control subjects. The cases and the control subjects were matched with age and comorbidities. Ever use of tamoxifen was defined as a subject who had at least a prescription for tamoxifen before the index date. Never use of tamoxifen was defined as a subject who never had a prescription for tamoxifen before the index date. We used the multivariable logistic regression model to calculate the odds ratio (OR) and 95% confidence interval (CI) for ischemic cerebrovascular disease associated with tamoxifen use. Results: After adjusting for confounding variables, the adjusted OR of ischemic cerebrovascular disease was 2.5 for subjects with ever use of tamoxifen (95% CI 2.10, 2.97), compared with never use of tamoxifen. In addition, the adjusted OR of ischemic cerebrovascular disease was 1.15 (95% CI 1.10, 1.21) in subjects with ever use of tamoxifen as increase in use duration per 1 year. The adjusted OR of ischemic cerebrovascular disease was 2.54 (95% CI 2.03, 3.17) in subjects with ever use of tamoxifen as increase in dosage per 1 mg. Conclusions: Tamoxifen use is significantly associated with 2.5-fold increased odds of ischemic cerebrovascular disease among older women with breast cancer in Taiwan. There are duration-dependent and dose-dependent effects of tamoxifen use on the risk of ischemic cerebrovascular disease.

Abstract
BACKGROUND There are limited data on the effect of dual antiplatelet treatment with clopidogrel plus aspirin in patients with ischemic cerebrovascular disease and intracranial and extracranial arteriostenosis. The aim of our study was to evaluate the efficacy and safety of aspirin plus clopidogrel in the treatment of ischemic cerebrovascular disease with intracranial and extracranial arteriostenosis. METHODS Patients with clinically evident acute cerebral infarction or transient ischemic attack combined with intracranial and extracranial arteriostenosis (greater than 50%) who were unsuitable or reluctance to perform stent implantation were enrolled in this study. We randomly assigned these patients to receive clopidogrel (75 or 50 mg) plus aspirin (100 mg) or aspirin (100 mg) once daily through 90 days, and followed them for 90 days. We examined the main endpoints including the recurrence of stroke, death from cardiovascular causes, and bleeding events. RESULTS In all, 200 patients were recruited and followed for 90 days. Ischemic stroke occurred in 6 patients (9.1%) treated with 50 mg clopidogrel and aspirin, 6 patients (9.1%) receiving 75 mg clopidogrel and aspirin, whereas 19 patients (27.9%) in the aspirin group (aspirin alone vs copidogrel 50 mg plus aspirin; 95% confidence intervals 1.704-23.779, P < 0.05; aspirin alone vs copidogrel 75 mg plus aspirin; 95% confidence intervals 1.190-13.240, P < 0.05). There were more hemorrhagic events among recipients (3 patients [2.3%]) in the copidogrel plus aspirin group than aspirin recipients (0 patient [0%]), including 1 subcutaneous hemorrhage in the group of 50 mg clopidogrel and aspirin, doubling the number of nasal and gum bleeding in the group of 75 mg clopidogrel and aspirin (P > 0.05). No intracranial hemorrhage and gastro-intestinal hemorrhage occurred in these 3 groups. CONCLUSION Accordingly, 50 mg clopidogrel plus aspirin, and 75 mg clopidogrel plus aspirin were all superior to aspirin alone as stroke prevention in patients with cerebral infarction or transient ischemic attack combined with intracranial and extracranial arteriostenosis. The effect of secondary stroke prevention was similar between 50 mg clopidogrel plus aspirin and 75 mg clopidogrel plus aspirin. The therapy of 75 mg clopidogrel plus aspirin resulted in a worrisome tread in bleeding events.

Abstract
Long-term studies demonstrating the effect of pioglitazone use on primary prevention of ischemic cerebrovascular disease in older people with type 2 diabetes mellitus are lacking. This study investigated the relationship between pioglitazone use and first attack of ischemic cerebrovascular disease in Taiwan.We conducted a case-control study using the database of the Taiwan National Health Insurance Program. There were 2359 type 2 diabetic subjects aged ≥65 years with newly diagnosed ischemic cerebrovascular disease from 2005 to 2011 as the case group and 4592 sex- and age-matched, randomly selected type 2 diabetic subjects aged ≥65 years without ischemic cerebrovascular disease as the control group. The odds ratio (OR) with 95% confidence interval (CI) of ischemic cerebrovascular disease associated with pioglitazone use was measured by the multivariable unconditional logistic regression model.After adjustment for confounding factors, the multivariable logistic regression analysis disclosed that the adjusted ORs of first attack of ischemic cerebrovascular disease associated with cumulative duration of using pioglitazone were 3.34 for <1 year (95% CI 2.59-4.31), 2.53 for 1 to 2 years (95% CI 1.56-4.10), 2.20 for 2 to 3 years (95% CI 1.05-4.64), and 1.09 for ≥3 years (95% CI 0.55-2.15), respectively.Our findings suggest that pioglitazone use does not have a protective effect on primary prevention for ischemic cerebrovascular disease among older people with type 2 diabetes mellitus during the first 3 years of use. Whether using pioglitazone for >3 years would have primary prevention for ischemic cerebrovascular disease needs a long-term research to prove.

Abstract
Tetrandrine is one of the major active ingredients in Menispermaceae Stephania tetrandra S. Moore, and has specific therapeutic effects in ischemic cerebrovascular disease. Its use in vascular dementia has not been studied fully. Here, we investigated whether tetrandrine would improve behavioral and cellular impairments in a two-vessel occlusion rat model of chronic vascular dementia. Eight weeks after model establishment, rats were injected intraperitoneally with 10 or 30 mg/kg tetrandrine every other day for 4 weeks. Behavioral assessment in the Morris water maze showed that model rats had longer escape latencies in training trials, and spent less time swimming in the target quadrant in probe trials, than sham-operated rats. However, rats that had received tetrandrine showed shorter escape latencies and longer target quadrant swimming time than untreated model rats. Hematoxylin-eosin and Nissl staining revealed less neuronal necrosis and pathological damage, and more living cells, in the hippocampus of rats treated with tetrandrine than in untreated model rats. Western blot assay showed that interleukin-1β expression, and phosphorylation of the N-methyl-D-aspartate 2B receptor at tyrosine 1472, were lower in model rats that received tetrandrine than in those that did not. The present findings suggest that tetrandrine may be neuroprotective in chronic vascular dementia by reducing interleukin-1β expression, N-methyl-D-aspartate receptor 2B phosphorylation at tyrosine 1472, and neuronal necrosis.

Abstract
Buyanghuanwu decoction has been shown to protect against cerebral ischemia/reperfusion injury, but the underlying mechanisms remain unclear. In this study, rats were intragastrically given Buyanghuanwu decoction, 15 mL/kg, for 3 days. A rat model of cerebral ischemia/reperfusion injury was established by middle cerebral artery occlusion. In rats administered Buyanghuanwu decoction, infarct volume was reduced, serum vascular endothelial growth factor and integrin αvβ3 levels were increased, and brain tissue vascular endothelial growth factor and CD34 expression levels were increased compared with untreated animals. These effects of Buyanghuanwu decoction were partially suppressed by an angiogenesis inhibitor (administered through the lateral ventricle for 7 consecutive days). These data suggest that Buyanghuanwu decoction promotes angiogenesis, improves cerebral circulation, and enhances brain tissue repair after cerebral ischemia/reperfusion injury.

Abstract
To evaluate the correlations between aortic complex plaque (ACP) and the recurrence of cryptogenic ischemic cerebrovascular disease (CICVD), and to investigate the clinical significance of ACP in CICVD. Methods CICVD patients (aged 17 to 84 years) admitted into the Department of Neurology, Xuanwu Hospital, from July 2011 to December 2013, were consecutively recruited, and divided into ACP and non-ACP groups according to head and neck computerized tomographic (CT) angiography. Recurrences of cerebral ischemic events (CIEs) were compared between these groups after follow-up. Results A total of 117 patients were enrolled (ACP group: 69, non-ACP group: 48) and followed up for a mean of 9.86 months (range: 3-33). The average age of the ACP group was 62.88 years, with 59.4% older than 60 years; the average age of the non-ACP group was 50.29 years, with 37.5% older than 60 years. At the 6-month follow-up, the recurrence rate of CIEs in the ACP group was significantly higher than that of the non-ACP group (17.0% [7/47] and 0% [0/36], respectively; χ2 = 4.283, P = 0.046). The cumulative recurrence risk for CIEs of the ACP group was significantly higher than for the non-ACP group (P = 0.004). Multivariate Cox survival analysis showed that ACP presence was an independent risk factor for CIE recurrence for CICVD patients (relative risk [RR] = 7.803, 95% confidence interval [CI], 1.827~33.319, P = 0.006). Conclusions ACP increased the recurrence risk of CIE in CICVD, and elderly CICVD patients should receive greater attention regarding the significance of ACP in recurrent CICVD.

Abstract
The present study recruited 193 patients with ischemic cerebrovascular disease from Inpatient and Outpatient Departments at the Affiliated Hospital of Qingdao University Medical College, China from August 2008 to May 2010, as well as 120 healthy volunteers from the Medical Examination Center at the Affiliated Hospital of Qingdao University Medical College, China, who served as controls for this study. Patients and control subjects were from the Han population in northern China. Enzyme- linked immunosorbent assay analysis revealed increased levels of serum pregnancy-associated plasma protein-A (PAPP-A) in ischemic cerebrovascular disease patients compared with healthy controls. In addition, the patients exhibited greater frequency of genotype CC and C alleles in a missense A/C (Tyr/Ser) polymorphism (dbSNP: rs7020782) of exon 14 in the PAPP-A gene. Multiple-factor logistic regression analysis on correction of age, gender, history of smoking, hypertension, diabetes mellitus, hypercholesteremia, and ischemic stroke family history showed that the risk for ischemic cerebrovascular disease in the population without the A allele at the A/C genetic locus in exon 14 of the PAPP-A was 2-folds greater than the population expressing the A allele. These experimental findings suggested that ischemic cerebrovascular disease correlated with the C allele in exon 14 of PAPP-A. In addition, the A allele is likely a protective gene; individuals carrying the A allele were less prone to ischemic cerebrovascular disease compared with individuals without the A allele.

Abstract
Calcium antagonists are widely used in the clinical treatment of ischemic cerebrovascular disease because of their vascular and neuroprotective effects. Nimodipine, a typical calcium antagonist, can cross the blood-brain barrier and act selectively at neurons and blood vessels of target tissues, thus exerting neuroprotective effects. The aim of the present study was to explore the hot spots and future trends of research on the neuroprotective effects of nimodipine. We retrieved 425 articles on the neuroprotective effects of nimodipine that were indexed in the Web of the Science database between 2000 and 2014. The retrieved articles were analyzed using document analysis reporting and the derived information function in the Web of Science, and the information visualization software CiteSpace III. The reference co-citation network was plotted, and the high frequency key words in these publications were used to analyze the research fronts and development trends for nimodipine neuroprotection. According to these co-citation clusters, the research front of nimodipine neuroprotection is the use of randomized controlled trials to study nimodipine intervention of subarachnoid hemorrhage. Using time zone view analysis on hot spots labeled with a key word, the areas of interest in the field of nimodipine neuroprotection are nimodipine pharmacology and therapeutics, blood-brain barrier, trials, and anti-angiospasm.

Abstract
Penehyclidine hydrochloride can promote microcirculation and reduce vascular permeability. However, the role of penehyclidine hydrochloride in cerebral ischemia-reperfusion injury remains unclear. In this study, in vivo middle cerebral artery occlusion models were established in experimental rats, and penehyclidine hydrochloride pretreatment was given via intravenous injection prior to model establishment. Tetrazolium chloride, terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labeling and immunohistochemical staining showed that, penehyclidine hydrochloride pretreatment markedly attenuated neuronal histopathological changes in the cortex, hippocampus and striatum, reduced infarction size, increased the expression level of Bcl-2, decreased the expression level of caspase-3, and inhibited neuronal apoptosis in rats with cerebral ischemia-reperfusion injury. Xanthine oxidase and thiobarbituric acid chromogenic results showed that penehyclidine hydrochloride upregulated the activity of superoxide dismutase and downregulated the concentration of malondialdehyde in the ischemic cerebral cortex and hippocampus, as well as reduced the concentration of extracellular excitatory amino acids in rats with cerebral ischemia-reperfusion injury. In addition, penehyclidine hydrochloride inhibited the expression level of the NR1 subunit in hippocampal nerve cells in vitro following oxygen-glucose deprivation, as detected by PCR. Experimental findings indicate that penehyclidine hydrochloride attenuates neuronal apoptosis and oxidative stress injury after focal cerebral ischemia-reperfusion, thus exerting a neuroprotective effect.

Abstract
Interleukin-18 gene promoter polymorphisms are potential risk factors for ischemic cerebrovascular disease, and the –607C allele may increase ischemic stroke risk in the Han Chinese population. In the present study, we recruited 291 patients with ischemic cerebrovascular disease from the Affiliated Hospital of Qingdao University Medical College, China, and 226 healthy controls. Both patients and controls were from the Han population in northern China. Immunoresonance scattering assays detected increased serum amyloid A protein, C-reactive protein, and interleukin-18 levels in ischemic cerebrovascular disease patients compared with healthy controls. Analysis of the –607C/A (rs1946518) polymorphism in the interleukin-18 gene promoter showed ischemic cerebrovascular disease patients exhibited increased frequencies of the CC genotype and C alleles than healthy controls. Genotype and allele frequencies of the interleukin-18 –137G/C (rs187238) polymorphism and the –13T/C (rs11024595) polymorphism in the 5’-flanking region of serum amyloid A, showed no significant difference between the two groups. Multivariate logistic regression analysis on the interleukin-18 promoter A/C genetic locus, for correction of age, gender, history of smoking, hypertension, diabetes mellitus, hypercholesteremia, and an ischemic stroke family history, showed ischemic cerebrovascular disease risk in individuals without the A allele (C homozygotes) was 2.2-fold greater than in A allele carriers. Overall, our findings suggest that the –13T/C (rs11024595) polymorphism in the 5’-flanking region of serum amyloid A has no correlation with ischemic cerebrovascular disease, but the C allele of the –607C/A (rs1946518) polymorphism in the interleukin-18 promoter is a high-risk factor for ischemic cerebrovascular disease in the Han population of northern China. In addition, the A allele is likely a protective gene for ischemic cerebrovascular disease.

Abstract
Thirty-four patients with cerebral infarction and 18 patients with transient ischemic attack were examined by multi-slice spiral CT scan, CT perfusion imaging, and CT angiography within 6 hours after onset. By CT perfusion imaging, 29 cases in the cerebral infarction group and 10 cases in the transient ischemic attack group presented with abnormal blood flow perfusion, which corresponded to the clinical symptoms. By CT angiography, various degrees of vascular stenosis could be detected in 41 patients, including 33 in the cerebral infarction group and eight in the transient ischemic attack group. The incidence of intracranial artery stenosis was higher than that of extracranial artery stenosis. The intracranial artery stenosis was located predominantly in the middle cerebral artery and carotid artery siphon, while the extracranial artery stenosis occurred mainly in the bifurcation of the common carotid artery and the opening of the vertebral artery. There were 34 cases (83%) with convict vascular stenosis and perfusion abnormalities, and five cases (45%) with perfusion abnormalities but without convict vascular stenosis. The incidence of cerebral infarction in patients with National Institutes of Health Stroke Scale scores ≥ 5 points during onset was significantly higher than that in patients with National Institutes of Health Stroke Scale scores < 5 points. These experimental findings indicate that the combined application of various CT imaging methods allows early diagnosis of acute ischemic cerebrovascular disease, which can comprehensively analyze the pathogenesis and severity of acute ischemic cerebrovascular disease at the morphological and functional levels.

Abstract
Dragon's blood is a bright red resin obtained from Dracaena cochinchinensis (Lour.) S.C.Chen (Yunnan, China). As a traditional Chinese medicinal herb, it has great traditional medicinal value and is used for wound healing and to stop bleeding. Its main biological activity comes from phenolic compounds. In this study, phenolic compounds were made into dropping pills and their protective effects were examined by establishing focal cerebral ischemia rats model used method of Middle Cerebral Artery Occlusion (MCAO), and by investigating indexes of neurological scores, infarct volume, cerebral index, cerebral water content and oxidation stress. Compared to model group, high, middle and low groups of Dragon's blood dropping pills could improve the neurological function significantly (p<0.01) and reduce cerebral infarct volume of focal cerebral ischemia rats remarkably (p<0.05-0.01). Meanwhile, each group could alleviate cerebral water content and cerebral index (p<0.05-0.01) and regulate oxidative stress of focal cerebral ischemia rats obviously (p<0.05-0.01). Activities of middle group corresponded with that treated with positive control drug. The results obtained here showed that Dragon's blood dropping pills had protective effects on focal cerebral ischemia rats.

Abstract
The association of the presence of cerebral microbleeds with antiplatelet use remains controversial. Long durations of antiplatelet use and vascular risk factors may have a greater impact on the development of cerebral microbleeds than short durations. The aim of this study was to determine whether the durations of antiplatelet use and vascular risk factors were associated with the presence of cerebral microbleeds in patients with ischemic cerebrovascular disease, who are frequently treated with antiplatelet agents. Two hundred twenty outpatients with ischemic cerebrovascular lesions (eg, cerebral infarcts and/or white matter lesions) detected by magnetic resonance imaging were examined. Patients with a history of cerebral hemorrhage were excluded. Cerebral microbleeds were observed in 71 (32.3%) patients. Deep or infratentorial microbleeds and strictly lobar microbleeds were observed in 53 (24.1%) patients and 18 (8.2%) patients, respectively. Aspirin use (odds ratio, 2.14; 95% confidence interval [CI], 1.02-4.73; P = .04) and a long duration (≥10 years) of aspirin use (odds ratio, 3.75; 95% CI, 1.31-10.86; P = .01) were significantly associated with deep or infratentorial microbleeds in the crude analysis, but this became nonsignificant after adjustment for hypertension and other confounding factors. The prevalence of antiplatelet use was significantly higher in the patients with hypertension than in those without hypertension (72.5% versus 49.1%, P = .002). Hypertension (odds ratio, 2.50; 95% CI, 1.11-6.41; P = .04) was significantly associated with the development of deep or infratentorial microbleeds even after adjustment for confounding factors and the association increased with the duration of hypertension. In conclusion, we found a significant association between aspirin use and deep or infratentorial microbleeds, but this association may reflect the presence of hypertension as a confounding factor.

Abstract
Scutellarein, the main metabolite of scutellarin in vivo, has relatively better solubility, bioavailability and bio-activity than scutellarin. However, it is very difficult to obtain scutellarein in nature compared with scutellarin. Therefore, the present study focused on establishing an efficient route for the synthesis of scutellarein by hydrolyzing scutellarin. The in vitro antioxidant activities of scutellarein were evaluated by measuring its scavenging capacities toward DPPH, ABTS+•, •OH free radicals and its protective effect on H2O2-induced cytotoxicity in PC12 cells using MTT assay method. The results showed that essential point to the synthesis was the implementation of H2SO4 in 90% ethanol in N2 atmosphere; scutellarein had stronger antioxidant activity than scutellarin. The results have laid the foundation for further research and the development of scutellarein as a promising candidate for ischemic cerebrovascular disease.
