Abstract
OBJECTIVES Methotrexate (MTX) is an antimetabolite agent widely used to manage a variety of tumors and autoimmune diseases. Nonetheless, MTX-induced intestinal intoxication is a serious adverse effect limiting its clinical utility. Inflammation and oxidative stress are possible mechanisms for MTX-induced intestinal toxicity. Vinpocetine (VNP) is a derivative of the alkaloid vincamine with potent anti-inflammatory and antioxidant effects. The current study investigated the protective intestinal impact of VNP in attenuating MTX-induced intestinal intoxication in rats. MATERIALS AND METHODS VNP was administered orally in a dose of 20 mg/kg, while MTX was injected intraperitoneal in a dose of 20 mg/kg. RESULTS VNP administration attenuated drastic histological changes induced by MTX and preserved both normal villus and crypt histology. VNP significantly attenuated oxidative injury by upregulating intestinal Nrf2 and HO-1 expression. VNP attenuated inflammation by reducing MPO, NO2-, TNF-α, and IL-1β levels mediated by downregulating NF-κB, NDAPH-oxidase, IRF3, p-JAK-1, and p-STAT-3 expressions. Moreover, VNP potently counteracted intestinal necroptosis by effectively downregulating RIPK1, RIPK3, MLKL, and caspase-8 proteins. CONCLUSION Therefore, VNP may represent a promising approach that can attenuate intestinal toxicity in patients receiving MTX.

Abstract
BACKGROUND Stroke is a leading cause of morbidity and mortality worldwide and a leading cause of disability. None of the neuroprotective agents have been approved internationally except edaravone in Japanese guidelines in acute ischemic stroke. We here discuss that there are two types of endogenous defense mechanisms (EDMs) after acute stroke for neuromodulation and neuroregeneration, and if both can be activated simultaneously, then we can have better recovery in stroke. AIMS AND OBJECTIVES We aimed to study the effect of combination of neuroprotection therapies acting on the two wings of EDM in acute large-vessel middle cerebral artery (LMCA) ischemic stroke. METHODS Sixty patients of LMCA stroke were enrolled and randomized within 72 h into two groups of 30 patients each. The control group received standard medical care without any neuroprotective agents while the intervention group received standard medical care combined with oral citicoline with vinpocetine for 3 months with initial 1 week intravenous and edaravone and cerebrolysin injection, started within 72 h of onset of stroke. Patients were assessed on the basis of the National Institutes of Health Stroke Scale, Fugl-Meyer Assessment Score, Glasgow Coma Scale, and Mini-Mental Status Examination at admission, discharge, and after 90 days. RESULTS The intervention group showed significant and early improvements in motor as well as cognitive recovery. CONCLUSION Combination therapy for neuroprotection which is acting on two pathways of EDM can be useful in functional recovery after acute ischemic stroke.

Abstract
This paper examines the use of vinpocetine in the context of clinical pharmacology. The main and active metabolite of vinpocetine is apovincaminic acid (AVA). Due to the scarce information in the literature on AVA pharmacokinetics, we propose a population pharmacokinetic (PopPK) model for AVA based on a study in healthy volunteers with three different formulations of vinpocetine. The suggested PopPK model (and simulations) could be helpful in ensuring the more effective and safer use of the vinpocetine in the future given the increasing range of suggested indications for its use.

Abstract
Neurological disorders with various etiologies impacting the nervous system are prevalent in clinical practice. Long non-coding RNA (lncRNA) molecules are functional RNA molecules exceeding 200 nucleotides in length that do not encode proteins, but participate in essential activities. Research indicates that lncRNAs may contribute to the pathogenesis of neurological disorders, and may be potential targets for their treatment. Phytochemicals in traditional Chinese herbal medicine (CHM) have been found to exert neuroprotective effects by targeting lncRNAs and regulating gene expression and various signaling pathways. We aim to establish the development status and neuroprotective mechanism of phytochemicals that target lncRNAs through a thorough literature review. A total of 369 articles were retrieved through manual and electronic searches of PubMed, Web of Science, Scopus and CNKI databases from inception to September 2022. The search utilized combinations of natural products, lncRNAs, neurological disorders, and neuroprotective effects as keywords. The included studies, a total of 31 preclinical trials, were critically reviewed to present the current situation and the progress in phytochemical-targeted lncRNAs in neuroprotection. Phytochemicals have demonstrated neuroprotective effects in preclinical studies of various neurological disorders by regulating lncRNAs. These disorders include arteriosclerotic ischemia-reperfusion injury, ischemic/hemorrhagic stroke, Alzheimer's disease, Parkinson's disease, glioma, peripheral nerve injury, post-stroke depression, and depression. Several phytochemicals exert neuroprotective roles through mechanisms such as anti-inflammatory, antioxidant, anti-apoptosis, autophagy regulation, and antagonism of Aβ-induced neurotoxicity. Some phytochemicals targeted lncRNAs and served a neuroprotective role by regulating microRNA and mRNA expression. The emergence of lncRNAs as pathological regulators provides a novel direction for the study of phytochemicals in CHM. Elucidating the mechanism of phytochemicals regulating lncRNAs will help to identify new therapeutic targets and promote their application in precision medicine.

Abstract
OBJECTIVE To evaluate the effect of vinpocetine therapy on clinical manifestations of chronic cerebral ischemia (CCI) and the blood concentrations of neuroinflammation markers (S100B, IL-1β). MATERIAL AND METHODS The study included 30 patients (mean age 61.6 [56.9; 67.9] years) with CCI that received vinpocetine (30 mg/day) for 3 months. Brain changes according to magnetic resonance imaging data were assessed using the STRIVE protocol. We analyzed the dynamics of changes in the clinical questionnaires: Montreal Cognitive Assessment Scale (MoCA), Hospital Anxiety and Depression Scale (HADS), Asthenic State Scale (ASS), Epworth Sleepiness Scale (ESS), general impressions of treatment (Global Rating of Change Scale, GRC). RESULTS In 3 months after vinpocetine therapy there was a significant improvement in cognitive status (MoCA: 25.1±2.1 vs 26.6±1.4 p<0.05), emotional state (HADS: 8.4±1.4 vs 7.1±1.8 (p<0.05)), daytime sleep parameters (ESS 8.4±2.1 vs 6.2±2.3 p<0.05) and reduction in asthenia (ASS: 72.2±18.1 vs 52.3±9.3, p<0.05). A significantly larger proportion of patients assessed the improvement from therapy as «moderate» and «pronounced» (GRC, n=22, 73.3%). Concentrations of S100B and IL-1β decreased significantly by the time therapy was completed. The overall severity of cerebrovascular changes according to MRI was significantly associated with blood levels of S100β, but not IL-1β: β=0.504, p=0.026, 95% CI 0.149-0.901, mainly due to periventricular changes in white matter (β=0.562, p=0.035, 95% CI (-0.024-0.820). Blood levels of S100β correlated with MoCA test results (r=0.6795), and IL-1β correlated with ESS scores (r=0. 6657). CONCLUSIONS The use of vinpocetine can significantly reduce the severity of cognitive and affective disorders, asthenia, normalize the circadian rhythm of sleep, suppress the expression S100β and IL-1β in patients with CCI. One of the vinpocetine's mechanisms of action may be the inhibition of neuroinflammation.

Abstract
Ischemic stroke is a disease with worldwide economic and social negative effects. It is a serious disease with high disability and mortality. Ionic imbalance, excitotoxicity, oxidative stress, and inflammation are induced during and after ischemic stroke. Cellular dysfunction, apoptosis, and necrosis are activated directly or indirectly mechanisms. The studies about neuroprotection in neurodegenerative diseases have increased in recent years. Data about the mechanisms of progressive molecular improvement in the brain tissue are increasing in acute ischemic stroke. Based on these data, preclinical and clinical studies on new neuroprotective treatments are being designed. An effective neuroprotective strategy can prolong the indication period of recanalization treatments in the acute stage of ischemic stroke. In addition, it can reduce neuronal necrosis and protect the brain against ischemia-related reperfusion injury. The current review has evaluated the recent clinical and experimental studies. The molecular mechanism of each of the neuroprotective strategies is also summarized. This review may help develop future strategies for combination treatment to protect the cerebral tissue from ischemia-reperfusion injury.

Abstract
Cerebral infarction has become the main cause of death among Chinese residents, especially ischemic cerebral infarction. The existing CT technology is not very effective for the detection of cerebral infarction, and some angiography has problems such as blurring and shadowing. In order to understand the treatment methods and effects of patients with cerebral infarction, this article observes the effect of nursing BPR on thrombolytic efficacy and prognosis of patients with cerebral infarction based on CT images. The patients were divided into thrombolytic group and nonthrombolytic group, and a simple rating scale was used to assess the motor function of the patients' limbs, and the stroke scale was used to assess the patient's neurological function. Compare the baseline data, the time of admission, 24 hours and 7 days, the scores before and after treatment, and the ratio between the two groups. According to the monitoring, record each time point. The analysis of the occurrence of primary endpoint was events and secondary endpoint events and risk factors affecting limb motor function. The results of the study found that, based on the computer scanning observation of nursing BPR, compared with the traditional model, the patient's bleeding was significantly reduced, and the time required for nursing was also reduced by more than 50% compared with the traditional model. Compared with the traditional nursing model, the satisfaction of patients with the BPR nursing model is nearly 40% higher than that of the traditional nursing model. This shows that the observation of thrombolytic effect in patients with cerebral infarction based on computed tomography and BPR nursing can produce good therapeutic effects.

Abstract
BACKGROUND Vinpocetine as a neuroprotective agent is effective in acute ischemic stroke in some randomized controlled trials (RCTs). Since the last systematic review has been published in 2008, which didn't find conclusive evidence favoring its use, two more RCTs have also been completed. METHODS Relevant electronic databases were searched with a suitable combination of Medical Subject Headings terms to detect publications describing RCTs exploring the safety and efficacy of vinpocetine in patients with acute ischemic stroke. The risk of bias was determined by using the Cochrane Collaboration's tool for assessing the risk of bias in RCTs after full-text review and relevant data extraction. Higgins and Thompson's I2 method was used to assess heterogeneity in studies. The presence of publication bias was assessed by Egger's test. We used a random effect model when I2 was more than 50% and a fixed-effect model for other parameters. RESULTS Four placebo-controlled RCTs enrolling a total of 601 and 236 patients in vinpocetine and placebo groups, respectively, were included. The number of patients with death or significant disability was lower in the vinpocetine group than that in the placebo group at both 1 and 3 months (relative risk 0.80, 95% confidence interval [CI] 0.65-0.99 and relative risk 0.67, CI 0.48-0.92, p = 0.04 and 0.02, respectively). The degree of disability in participants at 1 month and 3 months was also lower in vinpocetine group than that in the placebo group (standardized mean difference (SMD) 0.49, 95% CI 0.03-0.95 and SMD 1.22, CI 0.23-2.24, p = 0.001 and 0.04, respectively). Change in mini-mental state examination score compared with baseline at trial enrolment was also better in the vinpocetine group than in the placebo group (pooled weighted mean difference 0.92, 95% CI 0.02-1.82, p = 0.04). CONCLUSIONS Vinpocetine has some promising efficacy in patients with ischemic stroke when used in the acute stage in reducing the disability, but presently there is not enough evidence to suggest that it also reduces case fatality. More double-blind, placebo-controlled RCTs of adequate sample size are needed before making recommendations for the routine administration of vinpocetine for all patients with acute ischemic stroke.

Abstract
Alzheimer's disease (AD) is one of such diseases that represent the most prominent cause of dementia in elderly people. To explore the possible neuroprotective effect as well as mechanism of action of Vinpocetine either alone or in combination with EGCG, CoQ10, or VE & Se in ameliorating aluminum chloride-induced AD in rats. Rats were received AlCl3 (70 mg/kg) intraperitoneal daily dose for 30 days along with EGCG (10 mg/kg, I.P), CoQ10 (200 mg/kg, P.O), VE (100 mg/kg, P.O) & Se (1 mg/kg, P.O) as well as Vinpocetine (20 mg/kg, P.O) either alone or in combination. Results revealed that the combination of Vinpocetine with EGCG showed the best neuroprotection. This protection in the brain was indicated by the significant decrease in Aβ and ACHE. The same pattern of results were shown in the levels of monoamines and BDNF. In addition, the combination of Vinpocetine with EGCG showed more pronounced anti-inflammatory (TNF-α, IL-1β) and antioxidant (MDA, SOD, TAC) effects in comparison to other combinations. These results were confirmed using histopathological examinations as well as DNA fragmentation assays. Vinpocetine with EGCG showed pronounced protection on neurons against AD induced by AlCl3 in rats.

Abstract
Low levels of nutrient intake are common in industrialized countries. This has negative implications on health and is associated with chronic diseases. Supplementation of vitamins, minerals, and key nutrients to optimal levels may, therefore, be beneficial for individual health and for the health economy. Although the use of supplements has become very common, due to a lack of monitoring, there is very limited data on the efficacy of supplementation with different formulas. In this study, we present the results of a randomized controlled study on the efficacy of a novel formulated nutraceutical, N247, in 250 healthy volunteers aged 26-75 years and a placebo control group (n = 35). The broad-spectrum formulation of N247 includes essential vitamins, minerals, and trace elements that are adequately balanced in regard to synergies and related metabolic functions. Moreover, tolerance, safety, and nutrient availability is an important aspect of daily, long-term use of N247. After 3 months of regular N247 use, levels of vitamins and minerals in serum were significantly increased in the N247 group compared with the control group and a placebo group, with excellent compliance rates. Coupled with additional natural ingredients that aim to increase the potency of the nutrients, N247 may represent a novel and beneficial supplement for individuals with nutritional deficiencies.

Abstract
Exosomes contribute to cell–cell communications. Emerging evidence has shown that microglial exosomes may play crucial role in regulation of neuronal functions under ischemic conditions. However, the underlying mechanisms of microglia-derived exosome biosynthesis are largely unknown. Herein, we reported that the microglial PDE1-B expression was progressively elevated in the peri-infarct region after focal middle cerebral artery occlusion. By an oxygen-glucose-deprivation (OGD) ischemic model in cells, we found that inhibition of PDE1-B by vinpocetine in the microglial cells promoted M2 and inhibited M1 phenotype. In addition, knockdown or inhibition of PDE1-B significantly enhanced the autophagic flux in BV2 cells, and vinpocetine-mediated suppression of M1 phenotype was dependent on autophagy in ischemic conditions. Co-culture of BV2 cells and neurons revealed that vinpocetine-treated BV2 cells alleviated OGD-induced neuronal damage, and treatment of BV2 cells with 3-MA abolished the observed effects of vinpocetine. We further demonstrated that ischemia and vinpocetine treatment significantly altered microglial exosome biogenesis and release, which could be taken up by recipient neurons and regulated neuronal damage. Finally, we showed that the isolated exosome per se from conditioned BV2 cells is sufficient to regulate cortical neuronal survival in vivo. Taken together, these results revealed a novel microglia-neuron interaction mediated by microglia-derived exosomes under ischemic conditions. Our findings further suggest that PDE1-B regulates autophagic flux and exosome biogenesis in microglia which plays a crucial role in neuronal survival under cerebral ischemic conditions.

Abstract
ABSTRACT Ischemic stroke is the leading cause of globe death and permanent disability, but its therapeutic strategies are limited. Over the past decades, multiprotein complexes called inflammasomes have been shown as promising targets in ischemic stroke. Here, we examined vinpocetine (Vinp), a synthetic drug, playing a neuroprotective role against ischemic stroke in mice through regulating NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation. Middle cerebral artery occlusion/reperfusion (MCAO/R) was applied to mimic ischemic stroke in vivo. Vinp was administrated by intraperitoneal injection with different dose (5 or 10 mg/kg) 1 hour after reperfusion. Then, neurological assessment and infarct size were performed, and interleukin-1β (IL-1β) and IL-18 levels were evaluated using ELISA. The levels of NLRP3 inflammasome components and its upstream nuclear factor-κB (NF-κB) were determined using real-time PCR or Western blot. The experimental results indicated that posttreatment with Vinp decreased cerebral infarct size, improved behavior recover, reduced NLRP3 inflammasome expression, and suppressed the transfer of NF-κB to nucleus and proinflammatory cytokine release in middle cerebral artery occlusion/reperfusion mice. In conclusion, this study demonstrates that Vinp alleviates ischemic stroke by regulating levels of NLRP3 inflammasome, NF-κB, and proinflammatory cytokines in vivo, offering an alternative medication for ischemic stroke associated with inflammation.

Abstract
Vinpocetine (VPN) is a synthetic ethyl-ester derivative of the alkaloid apovincamine from Vinca minor leaves. VPN is a selective inhibitor of phosphodiesterase type 1 (PDE1) that has potential neurological effects through inhibition of voltage-gated sodium channel and reduction of neuronal calcium influx. VPN has noteworthy antioxidant, anti-inflammatory, and anti-apoptotic effects with inhibitory effect on glial and astrocyte cells during and following ischemic stroke (IS). VPN is effective as adjuvant therapy in the management of epilepsy; it reduces seizure frequency by 50% in a dose of 2 mg/kg/day. VPN improves psychomotor performances through modulation of brain monoamine pathway mainly on dopamine and serotonin, which play an integral role in attenuation of depressive symptoms. VPN recover cognitive functions and spatial memory through inhibition of hippocampal and cortical PDE1 with augmentation of cyclic adenosin monophosphate and cyclic guanosin monophosphate ratio, enhancement of cholinergic neurotransmission, and inhibition of neuronal inflammatory mediators. Therefore, VPN is an effective agent in the management of IS and plays an integral role in the prevention and attenuation of poststroke epilepsy, depression, and cognitive deficit through direct cAMP/cGMP-dependent pathway or indirectly through anti-inflammatory and antioxidant effects.

Abstract
The paper reviews the literature on vascular cognitive impairment (VCI), the diagnosis widely used in foreign neurological practice, as well as chronic cerebral ischemia (CCI) and dyscirculatory encephalopathy (DEP), the common diagnoses in Russian neurological practice. According to the etiology, risk factors, and manifestations, Stages I and II DEP largely corresponds to moderate VCI; Stage III DEP does to severe VCI. The results of the author’s studies show that a considerable proportion of patients followed up with a diagnosis of CCI, DEP, have no signs of chronic cerebrovascular disease (CVD), but suffer from primary or secondary headache, vertigo of various origins, emotional disorders, and other diseases. The diagnosis of CCI, DEP should be based on the presence of CCI, the reliable neuroimaging signs of chronic CVD, and the ruling out of other diseases. When treating and preventing VCI, CCI, and DEP, a premium is placed upon both non-drug (regular physical activity, smoking cessation, rational nutrition) and drug therapy aimed at normalizing blood pressure and blood lipid spectrum, preventing blood clots, and improving cognitive functions.

Repurposing of the Nootropic Drug Vinpocetine as an Analgesic and Anti-Inflammatory Agent: Evidence in a Mouse Model of Superoxide Anion-Triggered Inflammation. Mediators Inflamm 2019; 2019:6481812.

Abstract
Clinically active drugs for the treatment of acute pain have their prescription limited due to the significant side effects they induce. An increase in reactive oxygen species (ROS) has been linked to several conditions, including inflammation and pain processing. Therefore, new or repurposed drugs with the ability of reducing ROS-triggered responses are promising candidates for analgesic drugs. Vinpocetine is a clinically used nootropic drug with antioxidant, anti-inflammatory, and analgesic properties. However, the effects of vinpocetine have not been investigated in a model with a direct relationship between ROS, inflammation, and pain. Based on that, we aimed to investigate the effects of vinpocetine in a model of superoxide anion-induced pain and inflammation using potassium superoxide (KO2) as a superoxide anion donor to trigger inflammation and pain. In the KO2 model, vinpocetine dose-dependently reduced pain-like behaviors (spontaneous pain and hyperalgesia), paw edema, and neutrophil and mononuclear cell recruitment to the paw skin (assessed by H&E staining, fluorescence, and enzymatic assays) and to the peritoneal cavity. Vinpocetine also restored tissue endogenous antioxidant ability and Nrf2 and Ho-1 mRNA expression and reduced superoxide anion production and gp91phox mRNA expression. We also observed the inhibition of IκBα degradation by vinpocetine, which demonstrates a reduction in the activation of NF-κB explaining the diminished production of IL-33, IL-1β, and TNF-α. Collectively, our data show that vinpocetine alleviates pain and inflammation induced by KO2, which is a mouse model with a direct role of ROS in triggering pain and other inflammatory phenomena. Thus, the results suggest the repurposing of vinpocetine as an anti-inflammatory and analgesic drug.

Abstract
Objectives: Vasodilating antihypertensives prevent stroke and potentially cerebral small vessel disease but their effects on cerebrovascular haemodynamics beyond blood pressure lowering are unclear. Methods: We searched PubMed, Medline, Embase, Cinahl, Psychinfo, Health Business Elite and Health Management Information Consortium for randomized studies of vasodilating medications, compared to no treatment or nonvasodilators, that reported effects on cerebral blood flow (CBF), mean blood flow velocity (MFV) or cerebrovascular reactivity. Absolute and standardized mean differences (SMD) were combined by inverse-variance weighted fixed or random-effects meta-analysis stratified by study design, population characteristics and vasodilator class. Results: In 35 studies reporting 57 comparisons, there was a reduction in SBP (−4.13 mmHg, −7.55 to −0.71, P = 0.018) but no change in MFV (ΔMFV 1.11, confidence interval −0.93 to 3.14, P = 0.29, 23 comparisons). MFV increased in patients with underlying conditions (3.41, 0.24 to 6.57, P = 0.04) but not in healthy study participants (−1.27, −5.18 to 2.64, P = 0.68), with no differences by vasodilating drug class. Cerebral pulsatility index was reduced across all studies (Δ pulsatility index −0.04, −0.07 to −0.02, P = 0.001; Δ pulsatility index -SMD −0.32, −0.47 to −0.16, P < 0.001), except in studies reporting responses to single drug doses (Δ pulsatility index 0.00, −0.09 to −0.08, P = 0.93). Despite evidence of reporting and publication bias, there was an apparent consistent reduction in CBF with vasodilators (CBF-SMD −0.24, −0.46 to −0.02, P = 0.03) with a significant increase in cerebrovascular reactivity-SMD (0.48, 0.13–0.83, P = 0.007). Conclusions: Despite reducing SBP, vasodilators did not significantly impair absolute CBF but improved cerebrovascular pulsatility and reactivity, suggesting therapeutic potential in preventing stroke and cerebral small vessel disease.

Abstract
The idiopathic inflammatory bowel diseases (IBD) comprise two types of chronic intestinal disorders: Crohn's disease and ulcerative colitis. Recruited neutrophils and macrophages contribute to intestinal tissue damage via production of ROS and NF-κB-dependent pro-inflammatory cytokines. The introduction of anti-TNF-α therapies in the treatment of IBD patients was a seminal advance. This therapy is often limited by a loss of efficacy due to the development of adaptive immune response, underscoring the need for novel therapies targeting similar pathways. Vinpocetine is a nootropic drug and in addition to its antioxidant effect, it is known to have anti-inflammatory and analgesic properties, partly by inhibition of NF-κB and downstream cytokines. Therefore, the present study evaluated the effect of the vinpocetine in a model of acid acetic-induced colitis in mice. Treatment with vinpocetine reduced edema, MPO activity, microscopic score and macroscopic damage, and visceral mechanical hyperalgesia. Vinpocetine prevented the reduction of colonic levels of GSH, ABTS radical scavenging ability, and normalized levels of anti-inflammatory cytokine IL-10. Moreover, vinpocetine reduced NF-κB activation and thereby NF-κB-dependent pro-inflammatory cytokines IL-1β, TNF-α, and IL-33 in the colon. Thus, we demonstrate for the first time that vinpocetine has anti-inflammatory, antioxidant, and analgesic effects in a model of acid acetic-induced colitis in mice and deserves further screening to address its suitability as an approach for the treatment of IBD.

Abstract
Vinpocetine, a derivative of the alkaloid vincamine, has been clinically used in many countries for treatment of cerebrovascular disorders such as stroke and dementia for more than 30 years. Currently, vinpocetine is also available in the market as a dietary supplement to enhance cognition and memory. Due to its excellent safety profile, increasing efforts have been put into exploring the novel therapeutic effects and mechanism of actions of vinpocetine in various cell types and disease models. Recent studies have revealed a number of novel functions of vinpocetine, including anti-inflammation, antagonizing injury-induced vascular remodeling and high-fat-diet-induced atherosclerosis, as well as attenuating pathological cardiac remodeling. These novel findings may facilitate the repositioning of vinpocetine for preventing or treating relevant disorders in humans.

Abstract
AIM To study the efficacy of a current regimen of treatment with cavinton for infusions and cavinton comforte in patients with ischemic stroke in acute and early recovery periods and to evaluate an impact of treatment on erythrocyte deformity using atomic power microscopy. MATERIAL AND METHODS One hundred and sixty-four patients with hemispheric ischemic stroke, aged from 30 to 79 years, were randomized into main (n=100) and control (n=64) groups. Patients of the main group received complex treatment (basic therapy and cavinton R for drop infusions (10 intravenously during 10 days) followed by cavinton R comforte in dose 10 mg, 1 tablet 3 times a day during 90 days). Patients of the control group received basic therapy only. NIHSS, the Rankin scale, the Barthel index, MMSE, MоCA, the Rivermead scale, Beck depression scale, HADS were used to measure the severity of patient's state. To study the erythrocyte membrane by estimating Young's modulus, dry preparations were made with the following scanning of erythrocytes using atomic power microscopy. RESULTS Positive changes on all scales were observed in both groups. Higher scores on NIHSS, Rankin, Barthel, MоCA, MMSE, Rivermead mobility index were found in the main group compared to the controls. There were no differences in scores on the Beck depression scale and HADS. A decrease in Young's modulus was found in the main group while in the control group this index remained unchanged. CONCLUSION More rapid and complete regression of neurological deficit, better recovery of self-care function, cognitive function and social activity, an increase in erythrocyte membrane elasticity were found in the main group compared to the control one. These results indicate the efficacy of cavinton R and cavinton R comforte in the regimen used in complex treatment in acute and early recovery periods after ischemic stroke.
