Abstract
Natural products (NPs) are endless sources of compounds for fighting against several pathologies. Many dysfunctions, including cardiovascular disorders, such as cardiac arrhythmias have their modes of action regulation of the concentration of electrolytes inside and outside the cell targeting ion channels. Here, we highlight plant extracts and secondary metabolites' effects on the treatment of related cardiac pathologies on hERG, Nav, and Cav of cardiomyocytes. The natural product's pharmacology of expressed receptors like alpha-adrenergic receptors causes an influx of Ca2+ ions through receptor-operated Ca2+ ion channels. We also examine the NPs associated with cardiac contractions such as myocardial contractility by reducing the L-type calcium current and decreasing the intracellular calcium transient, inhibiting the K+ induced contractions, decreasing amplitude of myocyte shortening and showed negative ionotropic and chronotropic effects due to decreasing cytosolic Ca2+. We examine whether the NPs block potassium channels, particular the hERG channel and regulatory effects on Nav1.7.

Inflammopharmacology 2023; 31:2939-2954. [PMID: 37740887 DOI: 10.1007/s10787-023-01339-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Accepted: 09/09/2023] [Indexed: 09/25/2023]
Abstract
OBJECTIVE Attention-deficit hyperactivity disorder (ADHD) is a psychiatric disorder characterized by symptoms of inattention, hyperactivity, and impulsivity. Stimulant medication is the main pharmacological treatment for ADHD. However, the traditional pharmacological treatments may have significant side effects; therefore, non-pharmacological approaches are needed. Thus, there has been growing interest in alternative herbal treatments. The aim of this review was to comprehensively assess the current evidence for plant-based treatment of ADHD in human and animal models, as well as their ability to modulate the inflammatory process. METHODS This study was an integrative review of the current evidence for the plant-based treatment of ADHD. The research involved using literature available on PubMed and Scopus databases. FINDINGS Spontaneously hypersensitive rats treated with baicalin exhibited significant reductions in locomotion, increased spatial learning skills, and increased levels of dopamine in the striatum. Supplementation with Sansonite improved memory and attention capacity. In human studies, Ginkgo biloba significantly improved the symptoms of inattention and reduced memory impairment. In studies conducted using Korean Red ginseng, Klamath, and Crocus sativus L., the patients showed significant improvements in symptoms of inattention and hyperactivity/impulsivity. Furthermore, we demonstrated that the identified plants modulate the inflammatory process through pro-inflammatory and anti-inflammatory cytokines, nitric oxide, Th cells, Toll-like receptor 4, and mitogen-activated protein kinases. CONCLUSION All the studies included in this review focused on plants with demonstrated potential against inflammatory processes, positioning them as promising candidates for ADHD treatment, due to their potential to attenuate or even prevent neuroinflammatory mechanisms.

Abstract
Complementary alternative medicine approaches are growing treatments of diseases to standard medicine practice. Many of these concepts are being adopted into standard practice and orthomolecular medicine. Age-related diseases, in particular neurodegenerative disorders, are particularly difficult to treat and a cure is likely a distant expectation for many of them. Shifting attention from pharmaceuticals to phytoceuticals and "bugs as drugs" represents a paradigm shift and novel approaches to intervention and management of age-related diseases and downstream effects of aging. Although they have their own unique pathologies, a growing body of evidence suggests Alzheimer's disease (AD) and vascular dementia (VaD) share common pathology and features. Moreover, normal metabolic processes contribute to detrimental aging and age-related diseases such as AD. Recognizing the role that the cerebral and cardiovascular pathways play in AD and age-related diseases represents a common denominator in their pathobiology. Understanding how prosaic foods and medications are co-metabolized with the gut microbiota (GMB) would advance personalized medicine and represents a paradigm shift in our view of human physiology and biochemistry. Extending that advance to include a new physiology for the advanced age-related diseases would provide new treatment targets for mild cognitive impairment, dementia, and neurodegeneration and may speed up medical advancements for these particularly devastating and debilitating diseases. Here, we explore selected foods and their derivatives and suggest new dementia treatment approaches for age-related diseases that focus on reexamining the role of the GMB.

Efficacy of Diterpene Ginkgolides Meglumine injection in elderly patients with ischemic stroke: A post hoc analysis of a randomized controlled trial. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 106:154391. [PMID: 35994847 DOI: 10.1016/j.phymed.2022.154391] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 06/06/2022] [Accepted: 08/10/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Elderly patients with ischemic stroke (IS) have worse functional outcomes and poorer quality of life after suffering a stroke than younger patients. The identification of effective agents is critical to optimizing the therapy of IS in elderly patients. PURPOSE To examine the efficacy of diterpene ginkgolides meglumine injection (DGMI) vs. Ginaton in treating patients with IS, across different age subgroups. METHODS Efficacy was determined through the post hoc analysis of a randomized controlled study, which had a cohort of 998 patients with IS. Participants were pooled and grouped by age (elderly [aged ≥ 65 yr] vs. non-elderly [aged < 65 yr]). The primary efficacy outcome was the proportion of patients with modified Rankin Scale (mRS) score ranging from 0 to 1 at 90 d. The secondary outcomes were neurological deficit (tested using the National Institutes of Health Stroke Scale [NIHSS] score) and quality of life (tested using the EuroQol-5 Dimension [EQ-5D] and EQ visual analog scale [EQ-VAS] questionnaires). RESULTS There were 399 (40%) patients in the elderly group (average age = 69.8±3.3 yr) and 599 (60%) patients in the non-elderly group (average age = 55.8±6.8 yr). The randomized treatment groups had similar baseline characteristics. For the elderly group, 174 (94%) of the 185 participants in the DGMI group and 169 (79%) of the 214 participants in the Ginaton group achieved the main outcome of a mRS score of 0-1 after three months (odds ratio [OR] = 0.87 [95% confidence interval [CI] = 0.81-0.93], p<0.001). For the non-elderly group, 301 (96%) of the 314 participants in the DGMI group and 237 (83%) of the 214 participants in the Ginaton group achieved the main outcome of a mRS score of 0-1 after three months (OR = 0.88 [95% CI = 0.84-0.92], p<0.001). The overall mean EQ-5D index score and EQ-VAS of the DGMI group were higher than that of the Ginaton group for elderly patients. After controlling other covariates including treatments, gender, weight, height and medical history, the results of mRS score, NIHSS score, EQ-5D index score, and EQ-VAS based on generalized linear model were similar to those of the single covariate analysis. CONCLUSIONS DGMI demonstrated a superior efficacy to Ginaton for patients with IS in both elderly and non-elderly ages.

Abstract
Bisphenol A (BPA) is a ubiquitous environmental toxin with deleterious endocrine-disrupting effects. It is widely used in producing epoxy resins, polycarbonate plastics, and polyvinyl chloride plastics. Human beings are regularly exposed to BPA through inhalation, ingestion, and topical absorption routes. The prevalence of BPA exposure has considerably increased over the past decades. Previous research studies have found a plethora of evidence of BPA’s harmful effects. Interestingly, even at a lower concentration, this industrial product was found to be harmful at cellular and tissue levels, affecting various body functions. A noble and possible treatment could be made plausible by using natural products (NPs). In this review, we highlight existing experimental evidence of NPs against BPA exposure-induced adverse effects, which involve the body’s reproductive, neurological, hepatic, renal, cardiovascular, and endocrine systems. The review also focuses on the targeted signaling pathways of NPs involved in BPA-induced toxicity. Although potential molecular mechanisms underlying BPA-induced toxicity have been investigated, there is currently no specific targeted treatment for BPA-induced toxicity. Hence, natural products could be considered for future therapeutic use against adverse and harmful effects of BPA exposure.

Abstract
Alzheimer's disease, a neurodegenerative disease, is one of the most common causes of dementia if elderly people worldwide. Alzheimer's disease leads to the alienation of individuals and their exclusion from social and professional life. It is characterized mainly by the degradation of memory and disorientation, which occurs as a result of the loss of neuronal structure and function in different brain areas. In recent years, more and more attention has been paid to use in the treatment of natural bioactive compounds that will be effective in neurodegenerative diseases, including Alzheimer's disease. G. biloba L. and its most frequently used standardized extract (EGb 761), have been used for many years in supportive therapy and in the prevention of cognitive disorders. The paper presents an overview of reports on the pathogenesis of Alzheimer's disease, as well as a summary of the properties of G. biloba extract and its effects on the possible pathogenesis of the disease. By exploring more about the pathogenesis of the disease and the benefits of G. biloba extract for patients with Alzheimer's disease, it will be possible to create an individualized therapeutic protocol to optimize the treatment.

Abstract
Date palm fruits and by-products such as seeds are a source of various elements with significant nutritional values like fibres, minerals, essential fatty acids, amino acids and phenolic compounds. The experimental part was carried out on date palm seeds from Bent Kbala cultivar, the chemical composition of the organic fraction was determined using the method of UV-visible spectrophotometer, thin layer chromatography (TLC) and high-performance liquid chromatography-diode array detection (HPLC-DAD). The results revealed the presence of catechic tannins and approximately 17 phenolic compounds, including two compounds, which were identified for the first time in the date palm sub-product, especially in seeds such as naringenin and rutine. The assessment of the antioxidant potential shows that date palm seeds have a significant potential compared to standard antioxidants commonly used in cosmetics and neutraceutics industries.

Abstract
PURPOSE To analyze the vascular morphology changes after consumption of Ginkgo biloba in healthy volunteers by optical coherence tomography angiography (OCTA). METHODS Sixty healthy volunteers without systemic and ocular disease were included in this prospective pilot study. After receiving the informed consent of the volunteers, Ginkgo biloba extract (120 mg oral capsule) was administered to sixty volunteers for 4 weeks, once a day in the morning. The main outcome measures were the difference between before and after four-week of consumption in best-corrected visual acuity (BCVA), retinal nerve fiber layer (RNFL) and subfoveal choroidal thickness (sfCT) with optical coherence tomography; whole, foveal, parafoveal and perifoveal regions' superior and deep macular vascular plexus vessel density, foveal avascular zone area (FAZ), FAZ perimeter (PERIM), vessel density in a 300 µm wide region around FAZ (FD-300), choroidal and outer retinal flow area, radial peripapillary capillary (RPC) vascular density of whole, inside the disc, peripapillary and four quadrants with OCTA. RESULTS The study group consisted of sixty eyes of 32 women and 28 men with a mean age of 20.57 ± 1.16 years. In post-consumption measurements, peripapillary and superior, inferior, temporal quadrant RPC vascular density (%) was statistically significantly higher than pre-consumption measurements (p 0.020, p 0.021, p 0.008 and p 0.014, respectively). No significant difference was observed for BCVA, sfCT, other macular or RPC vascular density and flow area OCTA parameters between measurements. CONCLUSION Four-week consumption of Ginkgo biloba leads to vascular morphological changes in RPC. Further clinical studies are needed to demonstrate its use and effects/benefits in glaucoma, optic neuropathy and other diseases affecting the optic nerve.

Abstract
Ginkgo biloba (GB) extracts have been shown to commonly induce biphasic dose responses in a range of cell types and endpoints (e.g., cochlea neural stem cells, cell viability, cell proliferation). The magnitude and width of the low dose stimulation of these biphasic dose responses are similar to those reported for hormetic dose responses. These hormetic dose responses occur within direct stimulatory responses as well as in preconditioning experimental protocols, displaying acquired resistance within an adaptive homeodynamic and temporal framework and repeated measurement protocols. The demonstrated GB dose responses further reflect the general occurrence of hormetic dose responses that consistently appear to be independent of the biological model, endpoint, inducing agent, and/or mechanism. These findings have important implications for consideration(s) of study designs involving dose selection, dose spacing, sample size, and statistical power. This illustrates and strengthens the need to characterize the low dose stimulatory response range and optimal dose in order to explore potential public health and clinical applications of plant-derived agents, such as GB.

Abstract
Depression is common in patients with myocardial infarction (MI), attributing to worse outcomes. Inflammatory response in the central nervous system (CNS) is considered to be a potential mechanism underlying MI induced depression. Our former research demonstrated Ginkgo biloba extract played an important role in the repression of hippocampus inflammation in heart failure mice with depressive behaviors. This study was designed to investigate the effect of Ginkgolide B (GB) on MI-induced depression-like behaviors in post MI mice. After MI surgery induced by coronary ligation, MI mice behaved depressingly, detected by open field test (OFT) and the sucrose preference test (SPT), which was reserved by GB treatment. Meanwhile, the reduction of 5-HT and increase of interleukin 1 beta (IL-1β) in median raphe nucleus and cortex indicated potential mechanisms underlying MI-induced depression-like behaviors, which were significantly reserved by GB treatment. Moreover, the consistent variation of IL-1β and phospho-STAT3 expression in brain tissues, indicated a role of STAT3 pathway in IL-1β production and anti-inflammatory effect of GB. In conclusion, GB has great benefits in effective treatment for depression post MI through reducing the levels of proinflammatory cytokines via STAT3 pathway, implicating potential effects in improving depression status in patients with MI.

Abstract
Spinal cord injury (SCI) is a severe trauma of the central nervous system characterized by high disability and high mortality. Clinical progress has been achieved in understanding the pathological mechanism of SCI and its early treatment, but the results are unsatisfactory. In China, increasing attention has been paid to the role of traditional Chinese medicine in the treatment of SCI. In particular, extracts from the leaves of Ginkgo biloba (maidenhair tree), which have been reported to exert anti-inflammatory and antioxidant properties and repair a variety of active cellular damage, have been applied therapeutically for centuries. In this study, we established a rat SCI model to investigate the effects of Ginkgo biloba leaves on decompression at different stages of SCI. The application of Ginkgo biloba leaves during the decompression of SCI at different time points, the neurological recovery of SCI, and the underlying molecular mechanism were explored. The findings provide reliable experimental data that reveal the mechanism of GBI (Ginkgo biloba injection) in the clinical treatment of SCI.

Molecules 2020; 25:molecules25081829. [PMID: 32316426 PMCID: PMC7221681 DOI: 10.3390/molecules25081829] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 04/12/2020] [Accepted: 04/15/2020] [Indexed: 01/26/2023] Open
Abstract
Ginkgo biloba leaf (GBL) is known as a potential source of bioactive flavonoids, such as quercetin, arresting the neuronal soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE)-zippering. Here, the GBL flavonoids were isolated in two different manners and then examined for their bioactivity, physicochemical stability, and biocompatibility. The majority of flavonoids in the non-hydrolyzed and acidolyzed isolates, termed non-hydrolyzed isolate (NI) and acidolyzed isolate (AI) hereafter, were rich in flavonol glycosides and aglycones, respectively. Glycosidic/aglyconic quercetin and kaempferol were abundant in both NI and AI, whereas a little of apigenin, luteolin, and isorhamnetin were found in AI. NI was more thermostable in all pH ranges than quercetin, kaempferol, and AI. NI and AI both inhibited neurotransmitter release from differentiated neuronal PC-12 cells. NI and AI showed 1/2–1/3 lower EC50/CC50 values than quercetin and kaempferol. The NI and AI exhibited no toxicity assessed by the tests on chorioallantoic membranes of hen’s eggs, removing toxicological concerns of irritation potential. Moreover, GBL isolates, particularly AI, showed antioxidant and anti-inflammatory activities in the use below the CC50 levels. Taken together, these results suggest that GBL isolates that are rich in antioxidant flavonoids are effective anti-neuroexocytotic agents with high stability and low toxicity.

Abstract
Ginkgo biloba L. is the eldest plant growing on the Earth; preparations made of its leaves and seeds represent an integral part of the Chinese medicine for over a millennium. The plant species was first discovered by Linnaeus in 1771, its name thereby originating from the Latin words bis (two) and lobus (lobe), which duly illustrate the specific shape of its leaf. Contemporary Ginkgo biloba L. plant based pharmaceuticals mostly comprise extracts recovered from leaves harvested during fall, when the concentration of active components reaches its peak. Recent investigations have managed to establish the chemical composition of the plant leaf, together with the mechanisms underlying its beneficial effects on rheological profile of the blood and acceleration of its flow. High price of these preparations and their vast popularity have soon become an incentive for counterfeiting Ginkgo biloba L. extracts and the release of bogus drugs comprising cheaper extracts coming from other plants. Namely, modern Ginkgo biloba L.-based medicinal products and food supplements comprise extracts recovered from the plant leaf that get to be standardized according to its key pharmacological active components, most often flavone glycosides (represented in the share of 22%-27%) and terpene trilactones (represented in the share of 6%-7%). The flavonoids that predominate such preparations and are most relevant from the pharmacological standpoint are quercetin, kaempferol and isorhamnetin, their total amount and mutual ratios, thereby being an unquestionable indicator of the extract authenticity. Therefore, most of the analyses aiming at verifying the authenticity of a given Ginkgo biloba L.-based product boil down to the analysis of these parameters. Counterfeiting involves partial or full replacement of the Ginkgo biloba L. extract (GBE) with a cheaper plant extract of a similar composition, the latter occasionally being enriched with an additional amount of flavonoids, most often quercetin, not originating from the Ginkgo biloba L. plant. The aim of this study was to verify the authenticity and quality of Ginkgo biloba L.-based products circulating on the Croatian market. To that effect, 10 samples of products produced by various manufacturers were analyzed in a certified laboratory. The parameters based on which the authenticity of the preparations was assessed were the shares of aglycones of typical ginkgo flavone glycosides, that is to say, quercetin, kaempferol and isorhamnetin, and mutual ratios of the established quantities of quercetin to kaempferol as the key clues to unmasking Ginkgo extracts counterfeiting. The amount of ginkgo flavone glycosides was established using high performance liquid chromatography. The analysis proved 80% of the samples analyzed to be conformant to the label statements as regards the total amount of flavone glycosides and their mutual ratios. In 20% of the samples, the ratio of quercetin to kaempferol deviated from normal values; on top of that, the presence of the phytoestrogen genistein, one of the components typically comprised by the Sophora japonica L. plant, was also proven, documenting counterfeiting of the GBE and its replacement by the Sophora japonica L. extracts in the samples under consideration. Due to the untrue label statements descriptive of these products, the information on the presence of pharmacologically active genistein was neglected to be mentioned despite its unfavorable health impact that can be expected in some consumer groups. The results of this study indicated the frequency of counterfeiting the Ginkgo biloba L.-based products found on the Croatian market to be deemed substantial. Therefore, a more rigorous and more thorough control of these products and sanctioning of irresponsible manufacturers and distributers is proposed, so as to contribute to a higher market representation of high-quality products, as well as to avoid health risks and downsize the rate of their counterfeiting.

Abstract
The role of viral infection in developing cancer was determined in the start of 20th century. Until now, 8 different virus-associated cancers have been discovered and most of them progressed in immunosuppressed individuals. The aim of the present study is to look into the benefits of natural products in treating virally infected cancers. The study focuses on bioactive compounds derived from natural sources. Numerous pharmaceutical agents have been identified from plants (vincristine, vinblastine, stilbenes, combretastatin, and silymarin), marine organisms (bryostatins, cephalostatin, ecteinascidins, didemnin, and dolastatin), insects (cantharidin, mastoparan, parectadial, and cecropins), and microorganisms (vancomycin, rhizoxin, ansamitocins, mitomycin, and rapamycin). Beside these, various compounds have been observed from fruits and vegetables which can be utilized in anticancer therapy. These include curcumin in turmeric, resveratrol in red grapes, S-allyl cysteine in allium, allicin in garlic, catechins in green tea, and β-carotene in carrots. The present study addresses various types of virally infected cancers, their mechanism of action, and the role of different cell surface molecules elicited during viral binding and entry into the target cell along with the anticancer drugs derived from natural products by targeting screening of bioactive compounds from natural sources.

Abstract
In this work, the aqueous two-phase extraction parameters and in vitro antioxidant activity of total flavonoids from Ginkgo biloba were investigated. The partition behavior of the flavonoids in an aqueous two-phase system (ATPS) was analyzed, the extraction parameters were optimized using response surface methodology, and the antioxidant activity of the flavonoids was determined by free-radical scavenging tests (1,1-diphenyl-2-picrylhydrazyl (DPPH) assay) and the ferric reducing/antioxidant power (FRAP) assay. The results showed that the concentration of ammonium sulfate was negatively correlated with the phase-volume ratio, whereas the concentration of polyethylene glycol was positively correlated. The maximum yield of flavonoids (4.11 mg g−1) was obtained under the following optimal extraction conditions: Concentration of polyethylene glycol (PEG)1500 30% and (NH4)2SO4 22% (mass fraction), and liquid/solid ratio 40:1 (mL g−1). The antioxidant activity tests showed that the flavonoids from the G. biloba leaf exhibited free-radical scavenging activity, with an IC50 of 2.66 mg L−1, which was superior to that of vitamin C. The free-radical scavenging ability of the flavonoids was proportional to the flavonoid concentration. The total reducing power of the Ginkgo flavonoids was slightly lower than that of vitamin C. In this study, the distribution of flavonoids in an ATPS was analyzed and a mathematical model for the ATPS extraction of Ginkgo flavonoids was established, which provides a reference for further development and utilization of G. biloba.

The Acute and Chronic Cognitive and Cerebral Blood Flow Effects of a Sideritis scardica (Greek Mountain Tea) Extract: A Double Blind, Randomized, Placebo Controlled, Parallel Groups Study in Healthy Humans. Nutrients 2018; 10:E955. [PMID: 30042362 PMCID: PMC6116054 DOI: 10.3390/nu10080955] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Revised: 07/12/2018] [Accepted: 07/16/2018] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND The presence of polyphenols such as hydroxy-cinnamic acids and flavonoids in Sideritis scardica (Greek mountain tea) are likely responsible for the cognitive and mood effects of its consumption and this could be underpinned by the ability of such polyphenols to prevent monoamine neurotransmitter reuptake and to increase cerebral blood flow (CBF). OBJECTIVE The current study extends the small amount of Sideritis scardica literature in humans by assessing both cognitive and mood outcomes in a sample of older adults, as well as blood pressure (BP) and CBF, in a subsample, utilizing near-infrared spectroscopy (NIRS). DESIGN This randomized, double-blind, placebo-controlled, parallel groups trial randomized N = 155, 50⁻70-year-old male and female participants who were assessed for the cognitive (N = 140), mood (N = 142), BP (N = 133) and CBF (N = 57) effects of two doses of Greek mountain tea (475 and 950 mg) as well as an active control of 240 mg Ginkgo biloba, and a placebo control, following acute consumption (Day 1) and following a month-long consumption period (Day 28). RESULTS Relative to the placebo control, 950 mg Greek mountain tea evinced significantly fewer false alarms on the Rapid Visual Information Processing (RVIP) task on Day 28 and significantly reduced state anxiety following 28 days consumption (relative also to the active, Ginkgo control). This higher dose of Greek mountain tea also attenuated a reduction in accuracy on the picture recognition task, on Day 1 and Day 28, relative to Ginkgo and both doses of Greek mountain tea trended towards significantly faster speed of attention on both days, relative to Ginkgo. Both doses of Greek mountain tea, relative to placebo, increased oxygenated haemoglobin (HbO) and oxygen saturation (Ox%) in the prefrontal cortex during completion of cognitively demanding tasks on Day 1. The higher dose also evinced greater levels of total (THb) and deoxygenated (Hb) haemoglobin on Day 1 but no additional effects were seen on CBF on Day 28 following either dose of Greek mountain tea. Ginkgo biloba led to lower levels of Ox% and higher levels of Hb on Day 1 and lower levels of both HbO and THb on Day 28. CONCLUSIONS The significantly improved cognitive performance following Greek mountain tea on Day 1 could be due to significant modulation of the CBF response. However, these improvements on Day 28 are more likely to be due to the reductions in state anxiety and, taken together, suggests that the former mechanism is more likely to facilitate acute cognitive effects and the latter more likely to underpin more prolonged cognitive improvements.

Abstract
Background: Astrogliosis has the potential to lead to harmful effects, namely, neuroinflammation, and to interfere with synapse sprouting. Previous studies have suggested that Lipocalin-2 (LCN2) acts as a key target in regulating the reaction of astrocytes. However, the underlying molecular mechanism is not fully elucidated. In the present study, we examined the neuroprotective and anti-inflammatory effects of Ginkgo biloba extract (EGB), a well-known extract with potential immunoregulatory properties in the nervous system. Methods: Triphenyltetrazolium chloride staining, hematoxylin-eosin staining, electron microscopy, and neurological assessments were performed in a microsphere-embolized rat model. Human astrocytes exposed to oxygen glucose deprivation (OGD) were used for in vitro experiments. Inflammatory cytokines, multi-labeling immunofluorescence, and Western blotting were used to investigate the molecular mechanisms underlying the EGB-mediated anti-inflammatory effects in vivo and in vitro. Results: EGB markedly attenuated cerebral infarction and neuronal apoptosis, reduced the inflammatory cytokine level, and alleviated neurological deficiencies in cerebral ischemic rats. After surgery, EGB significantly inhibited astrocyte activation, reduced the phosphorylation of STAT3 and JAK2 and decreased LCN2 expression. In vitro, EGB blocked OGD-induced STAT3 activation and the generation of pro-inflammatory cytokines in human astrocytes, and these effects were significantly enhanced by LCN2 overexpression. EGB downregulated these effects enhanced by LCN2 overexpression. Conclusion: EGB is demonstrated to mediate neuroinflammation, which protects against ischemic brain injury by inhibiting astrogliosis and suppresses neuroinflammation via the LCN2-JAK2/STAT3 pathway, providing insight into a promising therapeutic strategy for ischemic stroke.

Abstract
Background: Refugees and war survivors are at higher risk of developing mental health disorders. Anxiety and stress are caused by many factors, including a stressful environment that could cause fatigue and low quality of life. Despite the existence of many synthetic anxiolytic and antidepressant drugs, symptom management has still not been successful. Ginkgo biloba extract has been used as one of the potential herbal remedies to enhance cognitive functions. Psycho-education plays a significant role in alleviating psychological distress. However, the role of G. biloba in alleviating anxiety, stress and fatigue among refugees was not well studied previously. Objectives: In this study, we aimed to compare the effect of G. biloba and psycho-education with only psycho-education on refugees’ anxiety, stress and fatigue. Methods: A randomized controlled, pre-test–post-test design was used. Data were measured at baseline and 6 weeks later. Results: Providing psycho-education for the control group showed a non-significant improvement in outcome variables. However, adding G. biloba to psycho-education for the experimental group showed a significant reduction in mental, physical, activity fatigue and anxiety. Conclusion: The addition of G. biloba to the psycho-education proved superior to psycho-education alone. Therefore, combining the two approaches is beneficial in alleviating anxiety and fatigue.

Abstract
Aims and MethodTo assess and update the available data on use of ginkgo to treat dementia. A Medline search as conducted for the period January 1985 to October 2000. The search included other aspects of the usage of ginkgo, such as side-effects, mechanism of action and drug interactions.ResultsMost of the trials using ginkgo were to treat cerebral insufficiency. Only five trials could be identified that used ginkgo to treat dementia. There are no trials comparing ginkgo to cholinesterase inhibitors such as donepezil.Clinical ImplicationsGinkgo is generally well-tolerated and appears to ease the symptoms of dementia. Although it has been suggested that the effect is comparable to donepezil, confirmation from controlled studies is required.

Abstract
OBJECTIVES The aim of this randomized, double-blind, placebo-controlled trial was to determine the efficacy and safety of Ginkgo biloba extract in patients diagnosed with vascular cognitive impairment (VCI). METHODS A total of 90 patients (aged 67.1±8.0 years; 59 women) were randomly allocated (1:1:1) to receive G. biloba 120 mg, G. biloba 60 mg, or placebo during a 6-month period. Assessment was made for efficacy indicators, including neuropsychological tests scores (Sandoz Clinical Assessment Geriatric Scale, Folstein Mini-Mental State Examination, Mattis Dementia Rating Scale, and Clinical Global Impression) and transcranial Doppler ultrasound findings. Safety indicators included laboratory findings, reported adverse reactions, and clinical examination. RESULTS At the end of 6-month study period, G. biloba 120 and 60 mg showed a statistically significant positive effect in comparison with placebo only on the Clinical Global Impression score (2.6±0.8 vs 3.1±0.7 vs 2.8±0.7, respectively; P=0.038). The Clinical Global Impression score showed a significant deterioration from the baseline values in the placebo group (-0.3±0.5; P=0.021) as opposed to G. biloba groups. No significant differences were found in the transcranial Doppler ultrasound findings. Adverse reactions were significantly more common and serious in the placebo group (16 subjects) than in either of the two G. biloba extract groups (eight and nine subjects, respectively), whereas laboratory findings and clinical examinations revealed no differences between the groups receiving G. biloba extract and placebo. CONCLUSION According to our results, G. biloba seemed to slow down the cognitive deterioration in patients with VCI, but the effect was shown in only one of the four neuropsychological tests administered. However, because of this mild effect in combination with a few adverse reactions, we cannot say that it is ineffective or unsafe either. Further studies are still needed to provide unambiguous evidence on the efficacy and safety of G. biloba extract.

Abstract
Ginkgo biloba seeds and leaves have been used as a traditional herbal remedy for thousands of years, and its leaf extract has been consumed as a botanical dietary supplement for decades. Ginkgo biloba extract is a complex mixture with numerous components, including flavonol glycosides and terpene lactones, and is one of the most widely sold botanical dietary supplements worldwide. Concerns about potential health risks for the general population have been raised because of the widespread human exposure to Ginkgo biloba and its potential toxic and carcinogenic activities in rodents. The National Toxicology Program conducted 2-year gavage studies on one Ginkgo biloba leaf extract and concluded that there was clear evidence of carcinogenic activity of this extract in mice based on an increased incidence of hepatocellular carcinoma and hepatoblastoma. Recently, Ginkgo biloba leaf extract has been classified as a possible human carcinogen (Group 2B) by the International Agency for Research on Cancer. This review presents updated information on the toxicological effects from experimental studies both in vitro and in vivo to human case reports (caused by ginkgo seeds or leaves), and also summarizes the negative results from relatively large clinical trials.

Abstract
Numerous trials have been conducted evaluating the efficacy of ginkgo biloba in memory disorders. The active constituents of ginkgo biloba are antioxidants that scavenge free radicals, which have been implicated in the pathogenesis of memory disorders. These studies suggest that ginkgo biloba in doses up to 120 mg/day when taken for 2 years may halt the progression of the disease for at least six months. The biggest concern of using ginkgo biloba is associated with its effects on platelet activating factor, which may result in bleeding disorders. Additional studies are needed to evaluate ginkgo biloba in combination with other medications.

Abstract
Objective: To provide an overview of basic information required by pharmacists to advise patients on the proper use of selected herbs and phytomedicines (“dietary supplements”) as therapeutic agents. Data Sources: The vast literature on this topic in the English, German, and French languages has been researched by the author over a period of many years. Databases that were used include NAPRALERT and MEDLINE. Study Selection: Articles and books dealing with the current popularity of botanical medicine and with laws and regulations covering so-called dietary supplements, as well as information on selected toxic herbs and a few of the most popular beneficial herbs used for treating common ailments and syndromes. Data Synthesis: Studies suggest that many herbal products currently available are both safe and effective drugs. A few products on the US market are definitely unsafe for human consumption and use. Conclusions: The increasing popularity of botanicals, coupled with regulations that prohibit definitive labeling, requires pharmacists to acquire accurate information based on scientifically and clinically acceptable data to advise patients on their use. Useful remedies for several common ailments and information concerning their safety and usefulness provide a starting point for an understanding of this complex field.

Abstract
Introduction: Cellulite (from Italian “cellulite”) is a widely used term to indicate a common condition afflicting women (ie, fat-lobular hypertrophy, which is localized mainly on thighs and buttocks). Despite the fact that several physiopathologic factors have been proposed for localized fat-lobular hypertrophy, the arena seems to be limited to vascular damage and lobular hypertrophy. These 2 components are known as the possible target of many different plant extracts, which may play an important role in influencing and reducing vascular damage and lobular hypertrophy. Materials and Methods: This study was aimed at evaluating the efficacy of a multifunctional plant complex in the treatment of localized fat-lobular hypertrophy. The study was carried out on a group of 25 subjects with clinical evidence of cellulite and on a control group of 15 subjects that received a placebo (2 capsules per day for a period of 2 months). The instrumental investigation measured baseline, intermediate, and final values of the following biophysical parameters: weight; arterial blood pressure; circumference of hips, thighs, and ankles; cutaneous fold thickness of hips; and measurement of the superficial microcirculation. Moreover, there was also a baseline and final assessment of circulating thyroid hormones and clotting analysis. Evaluation of the antioxidant efficacy of the product was tested and proved. Results: Volunteers' weight remained relatively constant during the study. Significant variations were recorded in the measurements of other biophysical cutaneous parameters (the circumference of hips, thighs, ankles; cutaneous fold thickness; skin microcirculation; and ultrasonography) in the group that had used the nonplacebo product, whereas the group who used the placebo did not present any significant variations. The thermographic data recorded a significant increase at the end of treatment. Significant variations in arterial blood pressure measurements, already 1 month after treatment in the first group, were observed. Thyroid function remained within normal range both before and after treatment; the variation in total cholesterol, low-density lipoprotein, and triglycerides were of no significance. No significant alterations were noted in the prothrombin concentration, whereas activated partial thromboplastine time (aPTT) and fibrinogen values were significantly increased in the treated volunteers. There was a significant reduction of the lipid peroxidase count and increase in the plasma total antioxidant capacity in the subjects who were nonsmokers and smokers. Conclusions: The data collected indicate that this multifunctional plant complex can reduce the dimensions of thighs and hips; decrease the thickness of underlying fat tissue while maintaining relatively constant body weight; and in particular improve blood circulation, which leads to the improvement of heat perfusion.

Abstract
INTRODUCTION This study evaluated the protective effects of 2 commercial formats of Ginkgo biloba on motor alterations induced by cassava (Manihot esculenta Crantz) juice consumption in male Wistar rats. METHODS The effects were evaluated with the open field and swim tests at 0, 7, 14, 21, and 28 days of treatment, one hour after administering the product. RESULTS Compared to controls, open field crossings increased after day 21 of cassava juice consumption, and lateral swimming in the swim test was reported after day 7. CONCLUSION Ginkgo biloba extracts prevented motor alterations associated with cassava juice consumption, probably due to the flavonoid content in both formats of Ginkgo biloba.

Abstract
The Ginkgo biloba extract (GbE) is a commercial product used as a nutraceutic herbal remedy in Europe and US. It contains 27% of the polyphenols isorhamnetin, kaempferol, and quercetin, as antioxidants. We used male adult Wistar rats (200-300 g), divided into four groups: control group (treated with 5.0 mg/kg of sodium chloride, intravenous), titanium dioxide nanoparticles (TiO2-NPs) group (5.0 mg/kg, intravenous), GbE group (10 mg/kg, intraperitoneal), and GbE + TiO2-NPs group (treated 24 h before with 10 mg/kg of GbE, intraperitoneal), followed, 24 h later, by 5.0 mg/kg of TiO2-NPs intravenously. The statistical analysis was performed using Student's t-test for grouped data with ANOVA posttest. The GbE protected renal cells against the effects of TiO2-NPs because it reversed the increased activity of γ-glutamyltranspeptidase and the enzymatic activity of dipeptidylaminopeptidase IV at all times tested (0-5, 5-24, 24-48, and 48-72 h). Also it reversed the glucosuria, hypernatriuria, and urine osmolarity at three times tested (5-24, 24-48, and 48-72). Thus, we conclude that GbE has a beneficial activity in the cytoplasmic membranes of brush border cells on the renal tubules, against the adverse effects that can be produced by some xenobiotics in this case the TiO2-NPs, in experimental rats.

Abstract
BACKGROUND Glaucoma is a leading cause of irreversible blindness worldwide. A major symptom of this pathology is the loss to the visual field in a peripheral to central pattern. Flavonoids are polyphenol compounds sourced from plants, commonly found in green tea, red wine and cocoa, and they have neuroprotective and antioxidant characteristics proposed to be advantageous within the context of glaucoma. Currently, the literature presents conflicting evidence regarding the effect of flavonoids on patients with glaucoma and ocular hypertension; hence a systematic review and meta-analysis was conducted. METHOD Databases included in our literature search were EMBASE (1980-present), MEDLINE Ovid, Alternative and Complementary Medicine Database (AMED), Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Cochrane Central Register of Controlled Trials (CENTRAL). Meta-analysis was performed using RevMan 5 (Review Manager) 5 software, version 5.3 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen). The primary outcomes were visual field mean deviation (MD) and intraocular pressure (IOP). Secondary outcomes were ocular blood flow and blood pressure (BP). CONCLUSION Meta-analyses showed that flavonoids have a promising role in improving visual function in patients with glaucoma and ocular hypertension (OHT), and appear to play a part in both improving and slowing the progression of visual field loss.

Abstract
Our study was to review and evaluate the efficacy and safety of extract of Gb (EGb) as an adjuvant therapy to antipsychotics in chronic schizophrenia treatment. We searched Pubmed/Medline, Embase, PsycINFO, the Cochrane library, and especially the Chinese periodical databases. Finally, eight randomized, double-blind, placebo-controlled trials (RCTs) of 1033 patients were enrolled, with 571 cases in EGb group and 462 in placebo. The result showed that EGb had a significant difference in ameliorating total and negative symptoms of chronic schizophrenia as an adjuvant therapy to antipsychotics. Thus, the EGb therapy plus antipsychotics might be more efficacious. Although the studies describing adverse reactions showed no distinguishable difference between EGb and placebo group in mean total scores of Treatment Emergent Symptom Scale (TESS) or a Rating Scale for Extrapyramidal Side Effects (RSESE), the results of subscores varied in different studies. In addition, the severity of side effects of EGb might be related to its daily dosage. Therefore, the safety of EGb therapy in chronic schizophrenia treatment might need more evidence. And all of these eight trials were carried out in China; thus, the results might be restricted to the race and we need more high-quality studies of multi-center and randomized double-blind clinical trials to compare, analyze, and confirm the findings further.

Abstract
Herbal products have been used as conventional medicines for thousands of years, particularly in Eastern countries. Thousands of clinical and experimental investigations have focused on the effects and mechanisms-of-action of herbal medicine in the treatment of cardiovascular diseases (CVDs). Considering the history of clinical practice and the great potentials of herb medicine and/or its ingredients, a review on this topic would be helpful. This article discusses possible effects of herbal remedies in the prevention and treatment of CVDs. Crucially, we also summarize some underlying pharmacological mechanisms for herb products in cardiovascular regulations, which might provide interesting information for further understanding the effects of herbal medicines, and boost the prospect of new herbal products against CVDs.

Abstract
Since time immemorial homo sapiens are subjected to both health and diseases states and seek treatment for succor and assuagement in compromised health states. Since last two decades the progressive rise in the alternative form of treatment cannot be ignored and population seems to be dissatisfied with the conventional treatment modalities and therefore, resort to other forms of treatment, mainly complementary and alternative medicine (CAM). The use of CAM is predominantly more popular in older adults and therefore, numerous research studies and clinical trials have been carried out to investigate the effectiveness of CAM in the management of both communicable and non-communicable disease. In this current mini review, we attempt to encompass the use of CAM in chronic non-communicable diseases that are most likely seen in geriatrics. The current review focuses not only on the reassurance of good health practices, emphasizing on the holistic development and strengthening the body's defense mechanisms, but also attempts to construct a pattern of self-care and patient empowerment in geriatrics. The issues of safety with CAM use cannot be sidelined and consultation with a health care professional is always advocated to the patient. Likewise, responsibility of the health care professional is to inform the patient about the safety and efficacy issues. In order to substantiate the efficacy and safety of CAMs, evidence-based studies and practices with consolidated standards should be planned and executed.

Abstract
Background. SuperUlam is a proprietary blend of natural ingredients aimed at supporting brain health. We aimed to evaluate the effect of SuperUlam on attention and mood in healthy adults. Methods. Twenty healthy individuals aged 35–65 were enrolled in this randomized, double-blind, placebo-controlled, crossover study. Study duration was 3 weeks and consisted of 3 visits. Measurement of cognitive function included computer-based testing of reaction time, complex attention, working memory, sustained attention, and executive functioning. Mood testing was performed via the profile of mood states (POMS) survey and the Chalder fatigue scale. Results. Cognitive function testing demonstrated a significant improvement from baseline in executive functioning, cognitive flexibility, reaction time, and working memory in the product group only (P < 0.05). When comparing the study product to placebo, the data demonstrated a significant decrease in tension, depression, and anger (P < 0.05). There was no significant difference between the product and placebo in the other measures of mood, including vigor, fatigue, confusion, and total mood disturbance. No adverse events were reported. Conclusions. Supplementation with SuperUlam is safe to consume with potential benefits to cognitive function and mood.

Antiapoptotic Effects of EGb 761. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:495703. [PMID: 23983787 PMCID: PMC3745884 DOI: 10.1155/2013/495703] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/19/2013] [Revised: 06/19/2013] [Accepted: 06/27/2013] [Indexed: 12/13/2022]
Abstract
Ginkgo biloba extracts have long been used in Chinese traditional medicine for hundreds of years. The most significant extract obtained from Ginkgo biloba leaves has been EGb 761, a widely used phytopharmaceutical product in Europe. EGb 761 is a well-defined mixture of active compounds, which contains two main active substances: flavonoid glycosides (24-26%) and terpene lactones (6-8%). These compounds have shown antiapoptotic effects through the protection of mitochondrial membrane integrity, inhibition of mitochondrial cytochrome c release, enhancement of antiapoptotic protein transcription, and reduction of caspase transcription and DNA fragmentation. Other effects include the reduction of oxidative stress (which has been related to the occurrence of vascular, degenerative, and proliferative diseases), coupled to strong induction of phase II-detoxifying and cellular defense enzymes by Nrf2/ARE activation, in addition to the modulation of transcription factors, such as CREB, HIF-1 α , NF- κ B, AP-1, and p53, involved in the apoptosis process. This work reviews experimental results about the antiapoptotic effects induced by the standardized extract of Ginkgo biloba leaves (EGb 761).

Ginkgo biloba extract EGb 761 in the treatment of dementia: a pharmacoeconomic analysis of the Austrian setting. Wien Klin Wochenschr 2013; 125:8-15. [PMID: 23292640 DOI: 10.1007/s00508-012-0307-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2012] [Accepted: 11/16/2012] [Indexed: 10/27/2022]
Abstract
OBJECTIVE We used efficacy data from three clinical trials to investigate the pharmacoeconomic implications of treating noninstitutionalized Austrian dementia patients with a drug based on EGb 761R, a standardized extract from Gingkgo biloba. In a separate analysis, we compared the pharmacoeconomic aspects of achieving treatment success with EGb 761R and cholinesterase inhibitors. METHODS A fixed-effect model was used to conduct a metaanalysis of activities of daily living data from 1,201 patients diagnosed with dementia and treated with either EGb 761R (240 mg/day) or matched placebo for 22 or 24 weeks under double-blind conditions. From this analysis, the delay in activities of daily living (ADL)-based disease progression was estimated. Current Austrian drug reimbursement prices, physician fees, and federal subsidies for seven stages of home care were applied to calculate overall costs in four scenarios. For the comparison with cholinesterase inhibitors, metaanalysis data pertaining to overall clinical impression as published by the Cochrane Group were compared to corresponding data from our EGb 761R studies. RESULTS AND DISCUSSION The benefit of treatment with EGb 761R (240 mg/day) corresponds to a delay in ADL deterioration by 22.3 months compared to placebo. Overall net savings with EGb 761R treatment ranged from EUR 3,692 to EUR 29,577, mainly driven by delays in progression towards higher home care subsidies. For one additional therapy success with EGb 761R, EUR 530.88 was required. In a tentative cost comparison, cholinesterase inhibitors required higher expenses to achieve treatment success.

Abstract
The present study aimed to estimate the prevalence of elderly using potentially inappropriate medications (PIM) and with occurrence of potentially hazardous drug interactions (PHDI); to identify the risk factors for the prescription of PIM and to evaluate the impact of pharmaceutical intervention (PI) for the prescription of safer therapeutic alternatives. Therefore, a cross-sectional study was performed in a long-term care facility in São Paulo State, between December/2010 and January/2011. The medical records of the patients >60 years old who took any drugs were consulted to assess the pharmacotherapeutic safety of the medical prescriptions, in order to identify PIM and PHDI, according to the Beers (2003) and World Health Organization criteria, respectively. PI consisted of a guidance letter to the physician responsible for the institution, with the suggestions of safer equivalent therapeutics. Approximately 88% of the elderly took at least one drug, and for 30% of them the PIM had been prescribed. Most of the PIM identified (53.4%) act on the central nervous system. Among the 13 different DI detected, 6 are considered PHDI. Polypharmacy was detected as a risk factor for PIM prescription. After the PI there was no change in medical prescriptions of patients who had been prescribed PIM or PHDI. The data suggests that PI performed by letter, as the only interventional, method was ineffective. To contribute it a wide dissemination of PIM and PHDI among prescriber professionals is necessary for the selection of safer treatment for elderly. Additionally, a pharmacist should be part of the health care team in order to help promote rational use of medicines.

Abstract
Ginkgo biloba extract (GBE) and anthocyanins are considered beneficial for various vascular diseases. This study was performed to evaluate the effect of GBE and anthocyanins on visual function in patients with normal tension glaucoma (NTG) based on the vascular theory of mechanisms of glaucomatous optic nerve damage. Retrospective analysis was carried out by a chart review of 332 subjects (209 men and 123 women) who were treated with anthocyanins (n=132), GBE (n=103), or no medication (control, n=97). Humphrey Visual Field (HVF) test, logarithm of the minimal angle of resolution best-corrected visual acuity (logMAR BCVA), intraocular pressure, blood pressure, and fasting blood glucose were determined before and after treatment. Complete ocular and systemic examinations were performed. The mean follow-up duration was 23.82±9.84 (range, 12-59) months; the mean anthocyanin treatment duration was 24.32±10.43 (range, 6-53) months, and the mean GBE treatment duration was 23.81±10.36 months (range, 6-59) months. After anthocyanin treatment, the mean BCVA for all eyes improved from 0.16 (±0.34) to 0.11 (±0.18) logMAR units (P=.008), and HVF mean deviation improved from -6.44 (±7.05) to -5.34 (±6.42) (P=.001). After GBE treatment, HVF mean deviation improved from -5.25 (±6.13) to -4.31 (±5.60) (P=.002). A generalized linear model demonstrated that the final BCVA was not affected by demographic differences among the groups. These results suggest that anthocyanins and GBE may be helpful in improving visual function in some individuals with NTG.

Herbal Extracts Combination (WNK) Prevents Decline in Spatial Learning and Memory in APP/PS1 Mice through Improvement of Hippocampal Aβ Plaque Formation, Histopathology, and Ultrastructure. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:478190. [PMID: 22811746 PMCID: PMC3395307 DOI: 10.1155/2012/478190] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/06/2012] [Revised: 05/10/2012] [Accepted: 05/10/2012] [Indexed: 12/12/2022]
Abstract
To investigate the cognitive enhancement effect of WNK, an extracts combination of P. ginseng, G. biloba, and C. sativus L. and possible mechanisms, 5-month-old APP/PS1 transgenic mice were used in this study. After 3 months of administration, all mice received Morris water maze (MWM) training and a probe test. Mouse brain sections were detected by immunohistochemistry, HE staining, and transmission electron microscopy. MWM results showed significant difference between transgenic mice and nontransgenic littermates (P < 0.05, P < 0.01). WNK-treated mice exhibited enhanced maze performance over the training progression, especially better spatial memory retention in probe test compared to transgenic mice (P < 0.05, P < 0.01) and better spatial learning and memory at the fourth day of MWM test compared to EGB761- (G. biloba extract-) treated ones (P < 0.05). Hippocampal Aβ plaque burden significantly differed between APP/PS1 and littermate mice (P < 0.001), while decreased Aβ plaque appeared in WNK- or EGB761-treated transgenic brains (P < 0.05). Neurodegenerative changes were evident from light microscopic and ultrastructural observations in transgenic brains, which were improved by WNK or EGB761 treatment. These data indicate WNK can reduce the decline in spatial cognition, which might be due to its effects on reducing Aβ plaque formation and ameliorating histopathology and ultrastructure in hippocampus of APP/PS1 mouse brain.

Abstract
OBJECTIVE To investigate the efficacy and safety of combined common femoral artery (CFA) endarterectomy with superficial femoral artery (SFA) stenting plus Shuxuening Injection infusion in patients with complex multifocal arterial steno-obstructive lesions of the lower extremities. METHODS From March 2006 to March 2011, 104 lower limbs in 96 patients with multilevel peripheral arterial steno-occlusive disease, involving SFA as well as CFA and deep femoral artery (DFA) orifice, were treated by combined surgical with endovascular therapy, such as SFA stenting as an adjunct to CFA endarterectomy and patch angioplasty with the great saphenous vein. Before the end of the operation, 20 mL of Shuxuening Injection was infused through the catheter located in the treated artery. Technical and hemodynamic success, as well as primary and primary-assisted patency, was determined according to the Society for Vascular Surgery Guidelines. During follow-up, clinical status assessment, ankle-brachial index (ABI) test, and duplex Doppler ultrasound were administered every 6 months, and computed tomography angiography or magnetic resonance angiography was performed at 12, 24, and 36 months after discharge. RESULTS All patients underwent successful combined CFA endarterectomy with SFA stenting treatment. The average ABI after the combination treatment increased from pretreatment of 0.32±0.21 to 0.82±0.24 (P<0.01). No perioperative death and major limb amputations occurred. The mean duration of follow-up for 104 limbs from 96 patients was 1,180 days (range, 196-2,064 days). During follow-up, 5 patients died due to myocardial infarction, cerebral infarction, or pneumonia, and 5 patients were lost to follow-up. There were 21 cases (21.4%) of restenosis, with 15 that occurred in-stent and 6 near the distal end of the stent. A total of 18 (18.3%) reinterventions were performed, including 6 balloon angioplasty, 8 restenting procedures, 2 bypass surgeries, and 2 major limb amputations. The primary patency rates were 92.2%, 76.8%, and 61.3% at 12, 24, and 36 months, respectively, while the primary-assisted patency rates were 94.4%, 83.2%, and 75.6% at 12, 24, and 36 months, respectively. CONCLUSION The combined CFA endarterectomy with SFA stenting plus Shuxuening Injection infusion appears to offer a safe, less invasive, and effective treatment option to patients with chronic lower extremity ischemia due to complex multifocal peripheral artery disease.
