Abstract:
Ischemic postconditioning (PC) is proved to efficiently protect diabetic patients with acute myocardial infarction from ischemia-reperfusion injury. We aimed to explore the protective roles of ischemic PC on diabetic retinopathy in tree shrews with diabetic cerebral ischemia. A diabetic tree shrew model was established through high-fat diet feeding combined with streptozotocin (STZ) injection, while cortical thrombotic cerebral ischemia was induced photochemically. Tree shrews were divided into the normal control group, sham operation group, diabetes mellitus group, diabetes mellitus+cerebral ischemia group, and diabetes mellitus+cerebral ischemia+PC group (in which the tree shrews with diabetic cerebral ischemia were treated with ischemic PC). H&E staining was used to examine the pathological changes in the retina, and immunohistochemistry was performed to determine the retinal expression of VEGF (vascular endothelial growth factor). The modeling resulted in 77% tree shrews with diabetes. Ischemic PC reduced the blood glucose levels in the tree shrews with diabetic cerebral ischemia. Tree shrews with diabetes had thinned retina with disordered structures, and these pathological changes were aggravated after cerebral ischemia. The retinopathy was alleviated after ischemic PC. Retina expression of VEGF was mainly distributed in the ganglion cell layer in tree shrews. Diabetes and cerebral ischemia increased retinal VEGF expression in a step-wise manner, while additional ischemic PC reduced retinal VEGF expression. Therefore, ischemic PC effectively alleviates retinopathy in tree shrews with diabetic cerebral ischemia, and this effect is associated with reduced retinal VEGF expression.

Abstract:
The ischemic penumbra is both a concept in understanding the evolution of cerebral tissue injury outcome of focal ischemia and a potential therapeutic target for ischemic stroke. In this review, we examine the evidence that angiogenesis can contribute to beneficial outcomes following focal ischemia in model systems. Several studies have shown that, following cerebral ischemia, endothelial proliferation and subsequent angiogenesis can be detected beginning four days after cerebral ischemia in the border of the ischemic core, or in the ischemic periphery, in rodent and non-human primate models, although initial signals appear within hours of ischemia onset. Components of the neurovascular unit, its participation in new vessel formation, and the nature of the core and penumbra responses to experimental focal cerebral ischemia, are considered here. The potential co-localization of vascular remodeling and axonal outgrowth following focal cerebral ischemia based on the definition of tissue remodeling and the processes that follow ischemic stroke are also considered. The region of angiogenesis in the ischemic core and its surrounding tissue (ischemic periphery) may be a novel target for treatment. We summarize issues that are relevant to model studies of focal cerebral ischemia looking ahead to potential treatments.

Abstract:
Cerebral ischemic stroke is characterized by acute ischemia in a certain part of the brain, which leads to brain cells necrosis, apoptosis, ferroptosis, pyroptosis, etc. At present, there are limited effective clinical treatments for cerebral ischemic stroke, and the recovery of cerebral blood circulation will lead to cerebral ischemia-reperfusion injury (CIRI). Cerebral ischemic stroke involves many pathological processes such as oxidative stress, inflammation, and mitochondrial dysfunction. Nuclear factor erythroid 2-related factor 2 (Nrf2), as one of the most critical antioxidant transcription factors in cells, can coordinate various cytoprotective factors to inhibit oxidative stress. Targeting Nrf2 is considered as a potential strategy to prevent and treat cerebral ischemia injury. During cerebral ischemia, Nrf2 participates in signaling pathways such as Keap1, PI3K/AKT, MAPK, NF-κB, and HO-1, and then alleviates cerebral ischemia injury or CIRI by inhibiting oxidative stress, anti-inflammation, maintaining mitochondrial homeostasis, protecting the blood–brain barrier, and inhibiting ferroptosis. In this review, we have discussed the structure of Nrf2, the mechanisms of Nrf2 in cerebral ischemic stroke, the related research on the treatment of cerebral ischemia through the Nrf2 signaling pathway in recent years, and expounded the important role and future potential of the Nrf2 pathway in cerebral ischemic stroke.

Abstract:
Aim. To study clinical features, functional and neuroimaging characteristics of the brain of patients with ischemic brain disease and epileptic seizures. Methods. 772 patients with acute and chronic cerebral ischemia (265 stroke patients with epileptic seizures and 174 patients with seizures on the background of chronic cerebral ischemia, and 203 patients with stroke and 130 patients with chronic cerebral ischemia without seizures) were comprehensively examined. The clinical neurological examination, electroencephalography, magnetic resonance imaging, ultrasound duplex scanning of extra- and intracranial arteries with the assessment of the level and degree of stenosis and cerebrovascular reactivity were carried out. Results. Focal seizures prevailed in patients with cerebral ischemia. In patients with epileptic seizures on the background of both ischemic stroke and chronic cerebral ischemia cortical localization of ischemic foci prevailed. Early epileptic seizures in patients with ischemic stroke developed with significantly more frequent localization of ischemic focus in the right hemisphere with the orientation vector of neuroimaging formation of the ischemic lesion in the caudal direction. In patients with chronic cerebral ischemia with epileptic seizures, along with frequent lesion of the cortex, more frequent damage of white matter of the brain was observed. In patients with acute and chronic ischemia of the brain with epileptic seizures, a higher incidence of stenosis of major arteries and predominance of impaired cerebrovascular reactivity in posterior cerebral circulation system were established. Conclusion. Multimodal examination of patients with acute and chronic cerebral ischemia allowed forming risk groups for epileptic seizures.

Abstract:
✓ Progression and recovery of ischemic and postischemic damage after occlusion of the middle cerebral artery and subsequent reperfusion were investigated in the gerbil. This study was performed by immunohistochemical reaction testing for tubulin and creatine kinase BB-isoenzyme to visualize the neuronal structure and by immunohistochemical reaction testing for astroprotein (an astrocyte-specific protein) to visualize reactive astrocytes. The earliest ischemic lesion became visible in the frontoparietal cortex after 7 minutes of ischemia as a laminar loss of the reaction for tubulin involving the neuropil, neuronal perikarya, and dendrites. The earliest lesion in the caudoputamen evolved after 30 minutes of ischemia. After reestablishment of cerebral circulation, the immunohistochemical ischemic lesions in the neuronal structure disappeared if the ischemic period was 10 minutes or less and partially disappeared even after ischemia for 15 minutes in the cerebral cortex, while the postischemic lesion in the caudoputamen disappeared even after ischemia for 15 minutes. Reactive astrocytes were detected in the cerebral cortex and caudoputamen as early as 24 hours after reperfusion, both in the areas with and without the neuronal lesions. No lesion was identified in the hippocampus or thalamus. This experimental model is suitable for investigation of rapidly progressive regional ischemia in the cerebral cortex and for comparison with other regional or global cerebral ischemia in the gerbil or other animal species.

Abstract:
CA1 neurons in the hippocampus, a brain structure involved in learning and memory, are selectively vulnerable to ischemic effects. In this study, the authors examined if duration of ischemia is directly related to extent of CA1 damage and degree of spatial learning deficit. Adult female Wistar rats received either 5-min or 10-min ischemia or sham surgery. Following recovery, rats were tested in the Morris water maze. Histological analysis showed moderate cell loss in CA1 (31%) and CA3 (12%) and minimal cell loss in CA2 (4%) with 5-min ischemia. Increased cell loss was seen in CA1 (68%), CA2 (16%), and CA3 (23%) with 10-min ischemia. Behavioral testing revealed that animals with 10-min ischemia have greater spatial learning deficits and they remain impaired across the test days compared to the 5-min ischemic group. Furthermore, degree of CA1 cell loss accounted for approximately 45% of the variance in spatial learning deficits in the ischemic group. The authors conclude that cell loss is largely confined to CA1 region in rats who received 5 and 10 min of ischemia and that increased ischemic duration results in persistent learning deficits in female rats; also, the degree of behavioral impairment is related to extent of CA1 cell loss.

Abstract:
OBJECTIVE: Despite cerebral ischemia being a frequent clinical pathologic state, the tolerance of neural tissue to oxygen absence and to reperfusion is controversial. This study aims to evaluate the effects of focal cerebral ischemia/reperfusion, by analyzing the mitochondrial respiration. METHOD: Sixty-four adult rats underwent focal cerebral ischemia by middle cerebral artery occlusion, during 15, 30 and 60 minutes, followed by 10 minutes or 19 hours of reperfusion. The effects of ischemia were analyzed measuring the O2 consumption by mitochondria in the ischemic and non-ischemic areas. RESULTS: There was compromise of the mitochondrial respiration after 30 and 60 minutes of ischemia, followed by 10 minutes of reperfusion but there was no alteration in this function after 19 hours of reperfusion. CONCLUSION: Compromise of the mitochondrial function occurred after 30 minutes of ischemia but, until one hour of ischemia, if the reperfusion was prolonged there was no evidence of ischemic/reperfusion injuries.

Abstract:
Panax notoginseng saponins (PNS), bioactive compounds, are commonly used to treat ischemic heart and cerebral diseases in China and other Asian countries. Most previous studies of PNS have focused on the mechanisms underlying their treatment of ischemic cardiovascular diseases but not cerebral ischemic diseases. This study sought to explore the pharmacological mechanisms underlying the effectiveness of PNS in treating cerebral ischemic diseases. Different experimental cerebral ischemia models (including middle cerebral artery occlusion (MCAO) and the blockade of four arteries in rats, collagen-adrenaline-induced systemic intravascular thrombosis in mice, thrombosis of carotid artery-jugular vein blood flow in the bypass of rats, and hypoxia tolerance in mice) were used to investigate the mechanisms underlying the actions of PNS on cerebral ischemia. The results indicated that (1) PNS improved neurological function and reduced the cerebral ischemia infraction area in MCAO rats; (2) PNS improved motor coordination function in rats with complete cerebral ischemia (blockade of four arteries), decreased Ca2+ levels, and ameliorated energy metabolism in the brains of ischemia rats; (3) PNS reduced thrombosis in common carotid artery-jugular vein blood flow in the bypass of rats; (4) PNS provided significant promise in antistroke hemiplegia and hypoxia tolerance in mice. In conclusion, PNS showed antagonistic effects on ischemic stroke, and pharmacological mechanisms are likely to be associated with the reduction of cerebral pathological damage, thrombolysis, antihypoxia, and improvement in the intracellular Ca2+ overload and cerebral energy metabolism.

Abstract Objective To investigate the expression of erythropoietin (EPO) after acupuncture preconditioning plus focal cerebral ischemia treatment. Methods Rat focal cerebral ischemia model and acupuncture preconditioning model were established. Animals were randomly assigned into different groups: control (focal cerebral ischemia) and acupuncture preconditioning plus focal cerebral ischemia, with 8 rats for each group. The expression of EPO after different treatments was determined by histological examination, immunohistochemistry and in situ hybridization. Results The mRNA and protein expressions of EPO could be detected in survival and necrotic neurons, glia as well as vascular endothelial cells. Focal cerebral ischemia promoted the expression of EPO. Significant enhanced EPO level was found in the ischemic peripheral zone after acupuncture preconditioning (P < 0.05). Conclusion Our results demonstrated that acupuncture preconditioning enhanced the expression of EPO in neurons, glia and vascular endothelial cells the ischemic peripheral zone, suggesting the involvement of EPO in acupuncture preconditioning-induced neuroprotection following focal cerebral ischemia. EPO may exert neuroprotective effects through promoting neurotrophic support and angiogenesis.

Abstract:
Neuronal loss (death) occurs selectively in vulnerable brain regions after ischemic insults. Astrogliosis is accompanied by neuronal death. It can change the molecular expression and morphology of astrocytes following ischemic insults. However, little is known about cerebral ischemia and reperfusion injury that can variously lead to damage of astrocytes according to the degree of ischemic injury, which is related to neuronal damage/death. Thus, the purpose of this study was to examine the relationship between damage to cortical neurons and astrocytes using gerbil models of mild and severe transient forebrain ischemia induced by blocking the blood supply to the forebrain for five or 15 min. Significant ischemia tFI-induced neuronal death occurred in the deep layers (layers V and VI) of the motor cortex: neuronal death occurred earlier and more severely in gerbils with severe ischemia than in gerbils with mild ischemia. Distinct astrogliosis was detected in layers V and VI. It gradually increased with time after both ischemiae. The astrogliosis was significantly higher in severe ischemia than in mild ischemia. The ischemia-induced increase of glial fibrillary acidic protein (GFAP; a maker of astrocyte) expression in severe ischemia was significantly higher than that in mild ischemia. However, GFAP-immunoreactive astrocytes were apparently damaged two days after both ischemiae. At five days after ischemiae, astrocyte endfeet around capillary endothelial cells were severely ruptured. They were more severely ruptured by severe ischemia than by mild ischemia. However, the number of astrocytes stained with S100 was significantly higher in severe ischemia than in mild ischemia. These results indicate that the degree of astrogliosis, including the disruption (loss) of astrocyte endfeet following ischemia and reperfusion in the forebrain, might depend on the severity of ischemia and that the degree of ischemia-induced neuronal damage may be associated with the degree of astrogliosis.

Abstract:
Cerebral ischemia is a life-threatening condition associated with a substantial morbidity and mortality. Hyperglycemia, a common coexisting phenomenon in both stroke and cardiac arrest (CA), may further aggravate ischemic brain injury. To date, the therapeutic possibilities are lim-ited and the search for new treatment modalities is warranted. One aspect of such a research could be to better understand the cerebral pathogenesis induced by hyperglycemic ischemia-reperfusion. We investigated the combination of ischemia and hyperglycemia in two experimental models of stroke and CA. The aims were to test the neuroprotective potential of the sulfonated nitrone 2-sulfophenyl-N-tert-butylnitrone (S-PBN) in focal hyperglycemic cerebral ischemia (1), to outline the short-terms effects of hyperglycemia in prolonged (2) and short CA (3) and to performed a global transcriptome analysis of brain from hyperglycemic and normoglycemic CA (4). In a stroke model rats were made hyperglycemic prior to transient middle cerebral artery oc-clusion and randomized to S-PBN or saline. We found that S-PBN may ameliorate hyperglyce-mic-ischemic brain damage by improving the neurological performance after 1 day of survival, but did not reduce the infarct size. To study the cerebral oxidative state and perfusion after CA, pigs were randomized and clamped at blood glucose levels of 8.5 ̶ 10.0 mmol/L (high) and 4.0 ̶ 5.5 mmol/L (normal), sub-jected to 12 ̶ min of CA, followed by 8 min of cardiopulmonary resuscitation (CPR), and ob-served for 180 min. Increased oxygenation was found at higher glucose levels measured by near-infrared light spec-troscopy after CA. Tendencies toward increased protein S100β and 15-keto-dihydro-prostaglandin F2α were observed in the hyperglycemic group. We hypothesized that in combination with a brief period of CA, the preischemic hyperglycemia would worsen the cerebral injury compared with normoglycemia. We used a glycemic protocol similar to that in Paper II, whereby pigs were subjected to 5 ̶ min of CA, followed by 8 min of CPR, and observed for 180 mins. An increased level of the cerebral marker S100β was found in hyperglycemic pigs compared with normoglycemic pigs after CA. Global transcriptome analysis using microarray analysis revealed a different early metabolic gene expression in hyperglycemic CA compared with normoglycemic CA.

Abstract:
Cerebral small vessel pathology is now known to be associated with the development of cognitive impairment and mild motor impairments such as gait disturbance in a variety of neurodegenerative diseases. This dissertation explores the hypothesis that blood brain barrier dysfunction is an early event in cerebral ischemia and contributes to the development of cerebral small vessel disease (CSVD). A common rodent model of CSVD is permanent bilateral common carotid artery occlusion in the rat. This model was used to study several aspects of the progression of CSVD including the timecourse of blood brain barrier permeability changes following the onset of ischemia, gait disturbance, the expression of tight junction proteins and cytokine expression. It was determined that BBB permeability was elevated for 2 weeks following BCCAO and ischemic rats displayed lower gait velocity. There was no change in expression of TJ proteins. However, ischemic rats had higher levels of some proinflammatory cytokines and chemokines in brain tissue with no obvious changes in plasma levels. The mechanisms underlying the increase in BBB permeability were studied in vitro using artificial barriers made of confluent rat brain microvascular endothelial cells. Cerebral ischemia has been reported to cause an increase in plasma toxicity, likely by elevating the numbers of circulating microparticles (MPs). MPs isolated from the plasma of ischemic rats were applied to artificial barriers where it was found that they act mainly as vectors of TNF-α signaling. MPs induce activation of caspase-3 and the Rho/Rho kinase pathways. It is concluded that most of the increase in barrier permeability is due to apoptosis and disassembly of actin cytoskeleton and disruption of adherens junctions IV and not an increase in transcellular transport. The effects of treatment with the type III phosphodiesterase inhibitor cilostazol on dye extravasation in the brain, glial activation, white matter damage and motor performance were evaluated. It was determined that cilostazol could improve the increased BBB permeability and gait disturbance and microglial activation in optic tract following BCCAO. Also, the effects of treatment with cilostazol on plasma toxicity in vivo (24h and 14d following BCCAO) and artificial barriers (in vitro) were assessed. It was found that cilostazol could reduce plasma toxicity at 24h and improve increased endothelial barrier permeability that is induced by MP treatment respectively. In summary BBB dysfunction occurs in the rat model of chronic cerebral hypoperfusion with no differences in expression of TJ proteins. There is a mild motor disturbance in the form of lower gait velocity following BCCAO. Cytokines released in brain tissue may be associated with pathological consequences following BCCAO while there is no significant difference in plasma levels and circulating MPs may play a role in BBB dysfunction.

Abstract:
We investigated coagulation changes in a group of patients with cerebral ischemia, ranging from transient ischemic attacks to cerebral infarction. Patients were studied acutely (within 72 hours of onset of ischemia) and again approximately 2 months following the initial examination. We evaluated platelet activation, fibrin generation, and fibrinolysis by measuring plasma beta-thromboglobulin (BTG), fibrinopeptide A (FPA), and fibrinopeptide B-beta 1-42 (FPB), respectively. We compared measurements in cerebral ischemia patients with a group of age -and sex-matched neurological inpatients without vascular disease ("patient controls") and a similarly matched group of normal volunteers ("normal controls"). BTG levels for 90 patients studied acutely were not significantly different compared to 58 of the same patients studied 2 months later, 16.4 ± 11.3 ng/ml (mean ± SD) versus 17.5 ± 10.2 ng/ml. Both values were significantly increased (p< .05) compared to normal controls (12.2 ± 6.5 ng/ml, n = 44); patient controls (13.2 ± 7.6 ng/ml, n = 18) were not significantly different from normals. In contrast, FPA measurements were significantly increased in acute patients compared to normals (3.3 ± 5.8 versus 1.0 ± 1.7 ng/ml, p< .05) while FPA levels 2 months post-ischemia (0.6 ± 0.9 ng/ml) were no different than normals. FPB measurements were not significantly different among either acute patients (6.5 ± 2.4 pmol/ml) or patients 2 months post-ischemia (4.8 ± 1.5 pmol/ml) compared to normals (6.5 ± 1.8 pmol/ml).In summary, we have found, among cerebral ischemia patients, sustained increases in BTG, acute increases in FPA, and normal FPB. These findings are compatible with a model of cerebral ischemia consisting of acutely increased fibrin generation without concomitant increased fibrinolytic activity, superimposed on a background of increased platelet activation.

Abstract:
During the operation, surgeons in neurosurgical area usually performed the multiple temporary occlusions of parental artery which may induce the neuronal damage. It is generally thought that neuronal damage by cerebral ischemia is associated with extracellular concentrations of the excitatory amino acids. In this experiment, we measured the dynamics of extracellular glutamate release in 11 vessel occlusion (VO) model during repeated within short interval. Changes in cerebral blood flow were monitored by laser-Doppler flowmetry simultaneously with cortical glutamate level measured by amperometric biosensor. During ischemia, the peak level of glutamate release was gradually decreased as 112.38±26.21 μM in first period, 82.63±18.50 μM in second period, and 48.58±11.89 μM in third period. The time interval between the ischemia induction and the beginning of glutamate release was increased as 106.7 ± 10.89 (sec) at first attack, 139.11 ± 3.87 (sec) in second attack, 169.00 ± 14.56 (sec) in third ischemic period. From the results of real-time monitoring about glutamate release in 11-VO model during repetitive ischemic episode, it was demonstrated that repetitive ischemia induced less glutamate release from neuronal cell than single ischemia due to endogeneous protective mechanism which delayed glutamate release time in later ischemic injury.

Abstract:
Cognitive impairments, such as memory and intelligence, attention and mental performance, usually suffer in diffuse brain damage, in particular in chronic cerebral ischemia. However, they can also occur in focal brain lesions, such as cerebral infarcts, reaching the degree of dementia. The aim of the study was to investigate the peculiarities of non-dementia cognitive disorders in patients with the consequences of cerebral infarction. We examined 30 patients with chronic cerebral ischemia with cerebral infarction at the age of 58-66 years (M=62.4) and a similar comparison group was chosen. The main results of the cognitive status assessment in patients with CHEM with suffered cerebral infarction showed a decrease in short-term visual and figurative memory, more so in men and with increasing age. There were also decreased productivity of attention, decreased level of abstract thinking, and weakened connection between logical thinking and attention, more pronounced in men and in the older age group. With a disease duration of more than 3 years, the volume of figurative memory and the abstract component of thinking decreased. The main conclusions are: cognitive disorders developing against the background of CIM worsen to a greater extent in men, in persons older than 60 years and in 3 years from the moment of cerebral infarction; short-term medication therapy has no significant effect on cognitive dysfunction, the significance of these results determines the need for long-term, at least 6 months, rehabilitative medication therapy.

Abstract:
The acceptance of aspirin therapy for prevention of cerebral ischemia is based onpositive results of several large clinicaltrials, and the usual dose is 1000-1500 mg/day. Several recent reports emphasize the adverse effects of aspirin and other nonsteroidal anti-inflamatory agents on renal function. We examined wether two extreme doses of aspirin (60 mg vs 1200 mg/day) could alter renal function in patients recently admitted to hospital with cerebral ischemia. We studied 33 patients with cerebralischemia and no history of ingestion of aspirin nor other drugs two weeks prior to admission. During the first 5 days all patients received a 50 mEq sodium diet and no drugs, while during the second 5 days (trial) the patients were randomly assigned (double blind) to placebo, aspirin 20 mg or aspirin 400 mg, 3 times daily, with meals.Overall, body weight increased by 650 gin patients taking 1400 mg/day of aspirin (p≺0,01), but not in patients taking 60 mg/day. Also increases in systolic and diastolic blood pressure did not reach significant differences. While waiting morereports, aspirin at doses near 1000 mg should be administered cautiously in sodium restricted patients with cerebral ischemia.Acute water retention may be specially troublesome.

Abstract:
Review question / Objective: The purpose of this protocol is to present a transparent and clear methodology for performing a systematic review and meta-analysis of the available literature aimed to answer the following question: among patients with acute ischemic stroke due to large vessel occlusion, is net water uptake (NWU), as measured in CT images, associated with (i) cerebrovascular complications, including malignant cerebral edema, secondary intracerebral hemorrhage, and (ii) post-stroke functional outcome as measured by the modified Rankin Scale. Condition being studied: Currently, the association between net water uptake with cerebrovascular complications or post-stroke functional outcomes is not well defined. Broocks found that NWU based on CT was an important marker for malignant edema in LVO patients and independently associated with clinical prognosis. Additionally, Nawabi indicated that a higher degree of NWU was a predictor of intracranial hemorrhage in patients with acute ischemic stroke treated with mechanical thrombectomy. Thus, a higher NWU might contribute to the development of stroke complications and poorer outcomes. However, no systematic review and meta-analysis to quantitatively summarize this evidence and help establish the predictive value of NWU in patients with acute ischemic stroke.
