However, the incidence of vascular epilepsy is low. The purpose of this study was to study vascular epilepsy features in a teaching university. It was a retrospective, descriptive and analytical study, conducted from 1st January 2015 to 31st December 2016 in Cotonou Teaching Hospital (CNHU-HKM), Benin. It involved 35 patients brought together through comprehensive sampling. Vascular epilepsy hospital attendance rate was 2%. There were simple partial seizures in 74.28% of cases while cerebral ischemia was recorded in 44.44% of patients. Neurological consultation after stroke occurrence was a protective factor against the occurrence of vascular epilepsy with significant p at 0.001.展开更多

Traditional Chinese Medicine(TCM) has proven effective in treating PSD through syndrome differentiation, yet existing animal models primarily reflect Western medical concepts and fail to incorporate the TCM principle of “同病异治”( treating the same disease with different methods). This paper provides a review of the current methods for constructing animal models of post-stroke depression(PSD) from the perspective of Traditional Chinese Medicine(TCM) syndrome differentiation and proposes multi-dimensional assessment indicators. By integrating TCM theories with modern biomedical techniques, this study offers a comprehensive framework for deepening the understanding of the pathogenesis and therapeutic evaluation of PSD. This approach not only contributes to advancing PSD research but also paves the way for innovative treatment strategies that combine traditional and modern medicine.展开更多

Given the ...Epilepsy is a leading cause of disability and mortality worldwide. However, despite the availability of more than 20 antiseizure medications, more than one-third of patients continue to experience seizures. Given the urgent need to explore new treatment strategies for epilepsy, recent research has highlighted the potential of targeting gliosis, metabolic disturbances, and neural circuit abnormalities as therapeutic strategies. Astrocytes, the largest group of nonneuronal cells in the central nervous system, play several crucial roles in maintaining ionic and energy metabolic homeostasis in neurons, regulating neurotransmitter levels, and modulating synaptic plasticity. This article briefly reviews the critical role of astrocytes in maintaining balance within the central nervous system. Building on previous research, we discuss how astrocyte dysfunction contributes to the onset and progression of epilepsy through four key aspects: the imbalance between excitatory and inhibitory neuronal signaling, dysregulation of metabolic homeostasis in the neuronal microenvironment, neuroinflammation, and the formation of abnormal neural circuits. We summarize relevant basic research conducted over the past 5 years that has focused on modulating astrocytes as a therapeutic approach for epilepsy. We categorize the therapeutic targets proposed by these studies into four areas: restoration of the excitation–inhibition balance, reestablishment of metabolic homeostasis, modulation of immune and inflammatory responses, and reconstruction of abnormal neural circuits. These targets correspond to the pathophysiological mechanisms by which astrocytes contribute to epilepsy. Additionally, we need to consider the potential challenges and limitations of translating these identified therapeutic targets into clinical treatments. These limitations arise from interspecies differences between humans and animal models, as well as the complex comorbidities associated with epilepsy in humans. We also highlight valuable future research directions worth exploring in the treatment of epilepsy and the regulation of astrocytes, such as gene therapy and imaging strategies. The findings presented in this review may help open new therapeutic avenues for patients with drugresistant epilepsy and for those suffering from other central nervous system disorders associated with astrocytic dysfunction.展开更多

Methods Databases were retrieved such as Cochrane Library, PubMed, Web of Sicence, EMbase, CBM, CNKI and WanFang Data so as to look up randomized controlled trials （RCT） of treating post-stroke depression with acupuncture and western medicine, and the time limit for the retrieval spanned from the date of database established to September 2013. By extracting data and evaluating methodological quality of included studies according to inclusion and exclusion criteria, RevMan 5.2 software was applied for Meta-analysis and evidence quality was assessed by adopting the GRADE system. Results Atotal of 23 RCTs （845 patients with post-stroke depression） were included in this study. It was revealed by Meta-analysis that the differences of the two groups were statistically significant in terms of HAMD scale scores measured at the end of the treatment by comparing the treatment of acupuncture and western medicine [SMD=0.26, 95% CI （0.11, 0.40）], but via susceptibility analysis （excluding low quality studies）, the differences were not statistically significant [SMD=-0.06, 95% CI （-0.37, 0.25）], and the reliability of the results was low; in terms of adverse events, the differences were statistically significant [RR= 0.32, 95% Cl （0.19, 0.53）], and the risk of adverse events reduced by 68% in the acupuncture group. From the assessment on evidence quality grade based on GRADE system, it was revealed that HAMD scores and adverse events were evidences with fairly low quality. Conclusion Although this system assessment showed that treating post-stroke depression with acupuncture was more effective compared with western medicine, the result was less reliable and quality of evidences was poor. The above-mentioned results need more high- quality randomized controlled trials for further verification.展开更多

Methods Sixty cases of post-stroke depression ranged from mild to middle degree were randomly divided into comprehensive therapy group and medication group, 30 cases in each group. In comprehensive therapy group, electroacupuncture at temple-three-needle was mainly applied and Fluoxetine Hydrochloride capsule was taken by oral administration; in medication group, Fluoxetine Hydrochloride capsule was applied by oral administration. Functional Independent Measure （FIM） Scale and WHOQOL-BREF evaluation results before and after treatment were compared after 4 weeks treatment. Results Comparing with the FIM scores before treatment, the differences in the two groups were significant （both P0.01）, and the improvement in comprehensive therapy group （74.97±9.52） was superior to that in medication group （66.70±9.23） （P0.01）. Signif icant differences were presented statistically in comparison of index scores of WHOQOL-BREF before and after treatment in two groups （P0.05, P0.01）, and it in comprehensive therapy group was superior to that in medication group （P0.05, P0.01）. Conclusion Activities of daily life and quality of life of post-stroke depression can be significantly improved by electroacupuncture at temple-three-needle and oral administration of Fluoxetine Hydrochloride capsule.展开更多

文摘BACKGROUND Post-stroke depression(PSD)is associated with hypothalamic-pituitary-adrenal(HPA)axis dysfunction and neurotransmitter deficits.Selective serotonin reuptake inhibitors(SSRIs)are commonly used,but their efficacy is limited.This study investigated whether combining SSRIs with traditional Chinese medicine(TCM)Free San could enhance their therapeutic effects.AIM To evaluate the clinical efficacy and safety of combining SSRIs with Free San in treating PSD,and to assess its impact on HPA axis function.METHODS Ninety-two patients with PSD were enrolled and randomly divided into control groups(n=46)and study groups(n=46).The control group received the SSRI paroxetine alone,whereas the study group received paroxetine combined with Free San for 4 weeks.Hamilton Depression Scale and TCM syndrome scores were assessed before and after treatment.Serum serotonin,norepinephrine,cortisol,cor-ticotropin-releasing hormone,and adrenocorticotropic hormone were measured.The treatment responses and adverse reactions were recorded.RESULTS After treatment,the Hamilton Depression Scale and TCM syndrome scores were significantly lower in the study group than in the control group(P<0.05).Serum serotonin and norepinephrine levels were significantly higher in the study group than in the control group,whereas cortisol,corticotropin-releasing hormone,and adrenocorticotropic hormone levels were significantly lower(P<0.05).The total efficacy rates were 84.78%and 65.22%in the study and control groups,respectively(P<0.05).No significant differences in adverse reactions were observed between the two groups(P>0.05).CONCLUSION Combining SSRIs with Free San can enhance therapeutic efficacy,improve depressive symptoms,and regulate HPA axis function in patients with PSD with good safety and clinical application value.
文摘Post-stroke epilepsy is a common complication of ischemic stroke which adversely affects the prognosis of patients.Clinical and radiological parameters cannot adequately predict the risk.Therefore,the discovery of biomarkers is imperatively needed for predicting post-stroke epilepsy.We conducted a systematic review of diagnostic and prognostic biomarkers for post-stroke epilepsy through a comprehensive literature search in different databases.All articles that met our inclusion criteria were assessed for quality using the modified Quality Assessment of Diagnostic Accuracy Studies questionnaire.Eight eligible studies were included in this systematic review.Out of 22 assessed biomarkers,nine biomarkers showed significant association with post-stroke epilepsy.The T allele of CD40(cluster of differentiation 40)−1C/T polymorphism,the CC genotype of TRPM6(transient receptor potential cation channel subfamily M member 6)rs2274924,the allele polymorphism of MAD2(mitochondrial aldehyde dehydrogenase 2),the mRNA level of interleukin-6(IL-6),the plasma level of endostatin,and the mRNA expression of IL-1βshow a positive correlation with post-stroke epilepsy;while S100 calcium-binding protein B,heat shock 70 kDa protein-8 and neuropeptide Y are inversely associated with post-stroke epilepsy.As a small number of patients were recruited,further studies are needed to confirm their potential use for predicting post-stroke epilepsy.
文摘Post-stroke epilepsy(PSE)is a common complication of stroke,signifcantly impacting patient’s quality of life.Repetitive transcranial magnetic stimulation(rTMS)is an emerging potential non-invasive treatment for PSE.This review explores current evidence for rTMS in PSE,highlighting its potential benefts and limitations.Initial studies suggested that rTMS may reduce the seizure burden.Some studies observed a trend towards fewer seizures within two weeks of treatment initiation,indicating a relatively rapid response.Additionally,rTMS may be more efective when used in combination with medication,particularly for patients with specifc lesion locations(frontal/temporal lobes)and seizure types(complex partial seizures).This points towards the potential of personalized treatment protocols.However,current evidence has limitations.Studies often involve small sample sizes and methodological variations,necessitating larger,well-designed trials with standardized protocols to confrm the efcacy and safety of rTMS in PSE.Future research should also focus on the optimization of treatment parameters,including stimulation frequency,duration,coil placement,and treatment course.Long-term studies are needed to evaluate the persistence of treatment efects on seizure control,cognitive function,and overall patient outcomes.Refning patient selection criteria and investigating the underlying mechanisms of therapeutic efects of rTMS in PSE are also crucial areas for future exploration.
文摘Epilepsy is a common neurological disease that not only causes difficulties in the work and life activities of patients,but also brings complex social problems.Cerebrovascular disease is currently the main cause of epilepsy in the elderly.With the increased survival rate of patients after stroke,the incidence of epilepsy after stroke has also increased.Effective prediction of epilepsy after stroke is extremely crucial for the prognosis of patients,the initiation of antiepileptic therapy and the reduction of epileptic seizures.In this review,we summarize and compare the current models for the prediction of epilepsy after stroke,including the SeLECT prediction model,Post-Stroke Epilepsy Risk Scale(PoSERS),CAVE score,electroencephalogram(EEG)prediction model,and Scandinavian Stroke Scale(SSS)score,in order to provide reference for clinical practice and future research.Prediction models can be selected based on the clinical classification of cerebrovascular events.The SeLECT score prognostic model is a better choice for ischemic stroke,especially for the exclusive prediction of mild post stroke epilepsy.The CAVE score model is suitable for intra-cerebral hemorrhage patients.It is simple and offers high correlation between the risk factors and epilepsy.The PoSERS score simultaneously predicts ischemic and hemorrhagic stroke,and is superior to other methods in specificity as well as positive and negative prediction rate.The SSS score,which only measures stroke severity,is not strictly considered as a mature predictor,but it can be used as a first step screening tool.A growing number of large studies are under the way to identify risk factors of poststroke epilepsy(PSE)and to improve the inclusion of predictive indicators.New and advanced findings by EEG recordings may further improve the prediction of PSE.

文摘The activation of the sirtuin1(SIRT1)/nuclear factor erythroid 2-related factor 2(Nrf2)/heme oxygenase 1(HO-1)pathway has been shown to mitigate oxidative stress-induced apoptosis and mitochondrial damage by reducing reactive oxygen species(ROS)levels.Clinical trials have demonstrated that Zhongfeng Xingnao Liquid(ZFXN)ameliorates post-stroke cognitive impairment(PSCI).However,the underlying mechanism,particularly whether it involves protecting mitochondria and inhibiting apoptosis through the SIRT1/Nrf2/HO-1 pathway,remains unclear.This study employed an oxygen-glucose deprivation(OGD)cell model using SHSY5Y cells and induced PSCI in rats through modified bilateral carotid artery ligation(2VO).The effects of ZFXN on learning and memory,neuroprotective activity,mitochondrial function,oxidative stress,and the SIRT1/Nrf2/HO-1 pathway were evaluated both in vivo and in vitro.Results indicated that ZFXN significantly increased the B-cell lymphoma 2(Bcl2)/Bcl2-associated X(Bax)ratio,reduced terminal deoxynucleotidyl transferase-mediated d UTP nickend-labeling(TUNEL)+cells,and markedly improved cognition,synaptic plasticity,and neuronal function in the hippocampus and cortex.Furthermore,ZFXN exhibited potent antioxidant activity,evidenced by decreased ROS and malondialdehyde(MDA)content and increased superoxide dismutase(SOD),catalase(CAT),and glutathione(GSH)levels.ZFXN also demonstrated considerable enhancement of mitochondrial membrane potential(MMP),Tom 20 fluorescence intensity,adenosine triphosphate(ATP)and energy charge(EC)levels,and mitochondrial complexⅠandⅢactivity,thereby inhibiting mitochondrial damage.Additionally,ZFXN significantly increased SIRT1 activity and elevated SIRT1,nuclear Nrf2,and HO-1 levels.Notably,these effects were substantially counteracted when SIRT1 was suppressed by the inhibitor EX-527 in vitro.In conclusion,ZFXN alleviates PSCI by activating the SIRT1/Nrf2/HO-1 pathway and preventing mitochondrial damage.
文摘BACKGROUND Post-stroke depression(PSD),a condition commonly developed in patients with chronic stroke,impairs both functional rehabilitation and daily living.AIM To comprehensively analyze PSD contributors in chronic phase stroke and construct a precise nomogram.METHODS Two hundred patients with chronic stroke admitted in over 7 years(January 2017 to January 2024),were enrolled and categorized into the PSD group(n=96)and the non-PSD(NPSD)group(n=104).Demographic characteristics,clinicopathological data,and biochemical indicators were collected and analyzed by univariate analysis.Significant predictors identified in the univariate analysis were subsequently incorporated into a binary logistic regression model to assess their independent effects on PSD risk.The discriminative ability/calibration of the developed PSD prediction nomogram was assessed.RESULTS Compared with the NPSD group,the PSD group included a higher proportion of patients aged≥60 years,divorced/widowed,with an education level below senior high school,presenting with≥2 comorbidities,exhibiting severe neurological impairment,and having multiple lesions.Additionally,the PSD group showed significantly higher neutrophil-to-lymphocyte ratio(NLR)and platelet-tolymphocyte ratio(PLR)than the NPSD group.After assigning values to significant predictors,multivariate analysis indicated that educational level(P=0.046),NLR(P<0.001),and PLR(P<0.001)were independently associated with PSD in patients with chronic stroke.The developed nomogram exhibited favorable discrimination performance.The nomogram's calibration remained accurate for high-risk stratification but displayed modest inconsistencies in lowand middle-risk categories.CONCLUSION Education level,NLR,and PLR independently contribute to PSD in patients with chronic stroke.The constructed nomogram effectively predicts PSD risk within the range of 0.10-0.90,presenting a valuable tool for clinical monitoring and risk assessment of PSD in patients with chronic stroke.

文摘Post-stroke depression(PSD) is a common psychiatric complication affecting nearly one-third of stroke survivors, leading to increased disability, mortality, and cognitive decline. Traditional Chinese Medicine(TCM) has proven effective in treating PSD through syndrome differentiation, yet existing animal models primarily reflect Western medical concepts and fail to incorporate the TCM principle of “同病异治”( treating the same disease with different methods). This paper provides a review of the current methods for constructing animal models of post-stroke depression(PSD) from the perspective of Traditional Chinese Medicine(TCM) syndrome differentiation and proposes multi-dimensional assessment indicators. By integrating TCM theories with modern biomedical techniques, this study offers a comprehensive framework for deepening the understanding of the pathogenesis and therapeutic evaluation of PSD. This approach not only contributes to advancing PSD research but also paves the way for innovative treatment strategies that combine traditional and modern medicine.

文摘Post-stroke depression(PSD)is a prevalent but often underdiagnosed complication affecting stroke survivors,with significant implications for recovery and quality of life.Emerging evidence suggests that central obesity,as measured by the weight-to-waist index(WWI),may play a crucial role in PSD risk and severity.Traditional obesity metrics,such as body mass index,may not accurately capture the impact of visceral fat distribution on neuropsychiatric outcomes.This letter highlights the growing recognition of WWI as a precise indicator of metabolic and inflammatory disturbances linked to post-stroke mental health.Integrating WWI into routine stroke rehabilitation assessments could facilitate early identification of high-risk patients and improve intervention strategies.Further research is needed to establish standardized WWI cutoff values and explore potential therapeutic targets for PSD prevention.
文摘Objective:To investigate the clinical efficacy of Xiaochaihu Decoction combined with Xiaoxianxiong Decoction in the treatment of post-stroke pneumonia.Methods:To complete the sample grouping comparison,all patients with post-stroke pneumonia were investigated,and the number of cases was 60.These patients’diseases were consistent with the dialectical standards of traditional Chinese medicine(phlegm-heat obstructing lungs).The patients were randomly divided into a control group(30 cases,treated with antibiotics and symptomatic methods)and a treatment group(30 cases,treated with Xiaochaihu Decoction and Xiaoxianxiong Decoction on the basis of the control group).Various indicators were compared.Results:The total clinical effective rates were 93%and 80%in the treatment group and the control group,respectively,with statistical significance(P<0.05).The improvement of various clinical symptoms was compared,and the values in the treatment group were reduced,showing significance(P<0.05).Analysis of serum factor indicators showed that the overall trend of the treatment group was reduced,and the comparison between groups was below 0.05.Conclusion:Xiaochaihu Decoction combined with Xiaoxianxiong Decoction has a significant clinical effect in the treatment of post-stroke pneumonia(phlegm-heat obstructing lungs syndrome),which can reduce inflammatory reactions and has few adverse reactions,worthy of clinical application.
文摘BACKGROUND The weight-to-waist index(WWI)serves as an innovative metric specifically designed to assess central obesity.However,the relationship between WWI and the prevalence of post-stroke depression(PSD)remains inadequately explored in the literature.AIM To elucidate the relationship between WWI and PSD.METHODS Data from the National Health and Nutrition Examination Survey 2005 to 2018 were analyzed.Multivariable logistic regression models and propensity score matching were utilized to investigate the association between WWI and PSD,with adjustments for potential confounders.The restricted cubic spline statistical method was applied to explore non-linear associations.RESULTS Participants with elevated WWI values had a significantly greater risk of developing PSD.Specifically,individuals in the higher WWI range exhibited more than twice the likelihood of developing PSD compared to those with lower WWI values(odds ratio=2.21,95%confidence interval:1.84-2.66,P<0.0001).After propensity score matching,the risk of PSD remained significantly elevated(odds ratio=1.43,95%confidence interval:1.09-1.88,P=0.01).Tertile analysis revealed that participants in the highest WWI tertile faced a significantly higher risk of PSD compared to those in the lowest tertile.Restricted cubic spline analysis further revealed a non-linear association,with the risk of PSD plateauing at higher WWI values.CONCLUSION There is a significant association between elevated WWI and increased risk of PSD.Thus,regular depression screening should be implemented in stroke patients with elevated WWI to enhance patient outcomes.

文摘Epilepsy is a leading cause of disability and mortality worldwide. However, despite the availability of more than 20 antiseizure medications, more than one-third of patients continue to experience seizures. Given the urgent need to explore new treatment strategies for epilepsy, recent research has highlighted the potential of targeting gliosis, metabolic disturbances, and neural circuit abnormalities as therapeutic strategies. Astrocytes, the largest group of nonneuronal cells in the central nervous system, play several crucial roles in maintaining ionic and energy metabolic homeostasis in neurons, regulating neurotransmitter levels, and modulating synaptic plasticity. This article briefly reviews the critical role of astrocytes in maintaining balance within the central nervous system. Building on previous research, we discuss how astrocyte dysfunction contributes to the onset and progression of epilepsy through four key aspects: the imbalance between excitatory and inhibitory neuronal signaling, dysregulation of metabolic homeostasis in the neuronal microenvironment, neuroinflammation, and the formation of abnormal neural circuits. We summarize relevant basic research conducted over the past 5 years that has focused on modulating astrocytes as a therapeutic approach for epilepsy. We categorize the therapeutic targets proposed by these studies into four areas: restoration of the excitation–inhibition balance, reestablishment of metabolic homeostasis, modulation of immune and inflammatory responses, and reconstruction of abnormal neural circuits. These targets correspond to the pathophysiological mechanisms by which astrocytes contribute to epilepsy. Additionally, we need to consider the potential challenges and limitations of translating these identified therapeutic targets into clinical treatments. These limitations arise from interspecies differences between humans and animal models, as well as the complex comorbidities associated with epilepsy in humans. We also highlight valuable future research directions worth exploring in the treatment of epilepsy and the regulation of astrocytes, such as gene therapy and imaging strategies. The findings presented in this review may help open new therapeutic avenues for patients with drugresistant epilepsy and for those suffering from other central nervous system disorders associated with astrocytic dysfunction.

文摘Complex genetic architecture is the major cause of heterogeneity in epilepsy,which poses challenges for accurate diagnosis and precise treatment.A large number of epilepsy candidate genes have been identified from clinical studies,particularly with the widespread use of next-generation sequencing.Validating these candidate genes is emerging as a valuable yet challenging task.Drosophila serves as an ideal animal model for validating candidate genes associated with neurogenetic disorders such as epilepsy,due to its rapid reproduction rate,powerful genetic tools,and efficient use of ethological and electrophysiological assays.Here,we systematically summarize the advantageous techniques of the Drosophila model used to investigate epilepsy genes,including genetic tools for manipulating target gene expression,ethological assays for seizure-like behaviors,electrophysiological techniques,and functional imaging for recording neural activity.We then introduce several typical strategies for identifying epilepsy genes and provide new insights into gene-gene interactions in epilepsy with polygenic causes.We summarize well-established precision medicine strategies for epilepsy and discuss prospective treatment options,including drug therapy and gene therapy for genetic epilepsy based on the Drosophila model.Finally,we also address genetic counseling and assisted reproductive technology as potential approaches for the prevention of genetic epilepsy.

文摘Epilepsy is a serious neurological disorder;however,the effectiveness of current medications is often suboptimal.Recently,stem cell technology has demonstrated remarkable therapeutic potential in addressing various neurological diseases,igniting interest in its applicability for epilepsy treatment.This comprehensive review summarizes different therapeutic approaches utilizing various types of stem cells.Preclinical experiments have explored the use and potential therapeutic effects of mesenchymal stem cells,including genetically modified variants.Clinical trials involving patientderived mesenchymal stem cells have shown promising results,with reductions in the frequency of epileptic seizures and improvements in neurological,cognitive,and motor functions reported.Another promising therapeutic strategy involves neural stem cells.These cells can be cultured outside the body and directed to differentiate into specific cell types.The transplant of neural stem cells has the potential to replace lost inhibitory interneurons,providing a novel treatment avenue for epilepsy.Embryonic stem cells are characterized by their significant capacity for self-renewal and their ability to differentiate into any type of somatic cell.In epilepsy treatment,embryonic stem cells can serve three primary functions:neuron regeneration,the maintenance of cellular homeostasis,and restorative activity.One notable strategy involves differentiating embryonic stem cells intoγ-aminobutyric acidergic neurons for transplantation into lesion sites.This approach is currently undergoing clinical trials and could be a breakthrough in the treatment of refractory epilepsy.Induced pluripotent stem cells share the same genetic background as the donor,thereby reducing the risk of immune rejection and addressing ethical concerns.However,research on induced pluripotent stem cell therapy remains in the preclinical stage.Despite the promise of stem cell therapies for epilepsy,several limitations must be addressed.Safety concerns persist,including issues such as tumor formation,and the low survival rate of transplanted cells remains a significant challenge.Additionally,the high cost of these treatments may be prohibitive for some patients.In summary,stem cell therapy shows considerable promise in managing epilepsy,but further research is needed to overcome its existing limitations and enhance its clinical applicability.

文摘Objective To assess the efficacy and safety of treating post-stroke depression with acupuncture compared to western medicine systematically. Methods Databases were retrieved such as Cochrane Library, PubMed, Web of Sicence, EMbase, CBM, CNKI and WanFang Data so as to look up randomized controlled trials （RCT） of treating post-stroke depression with acupuncture and western medicine, and the time limit for the retrieval spanned from the date of database established to September 2013. By extracting data and evaluating methodological quality of included studies according to inclusion and exclusion criteria, RevMan 5.2 software was applied for Meta-analysis and evidence quality was assessed by adopting the GRADE system. Results Atotal of 23 RCTs （845 patients with post-stroke depression） were included in this study. It was revealed by Meta-analysis that the differences of the two groups were statistically significant in terms of HAMD scale scores measured at the end of the treatment by comparing the treatment of acupuncture and western medicine [SMD=0.26, 95% CI （0.11, 0.40）], but via susceptibility analysis （excluding low quality studies）, the differences were not statistically significant [SMD=-0.06, 95% CI （-0.37, 0.25）], and the reliability of the results was low; in terms of adverse events, the differences were statistically significant [RR= 0.32, 95% Cl （0.19, 0.53）], and the risk of adverse events reduced by 68% in the acupuncture group. From the assessment on evidence quality grade based on GRADE system, it was revealed that HAMD scores and adverse events were evidences with fairly low quality. Conclusion Although this system assessment showed that treating post-stroke depression with acupuncture was more effective compared with western medicine, the result was less reliable and quality of evidences was poor. The above-mentioned results need more high- quality randomized controlled trials for further verification.
文摘Objective To explore the better treatment of post-stroke depression. Methods Sixty cases of post-stroke depression ranged from mild to middle degree were randomly divided into comprehensive therapy group and medication group, 30 cases in each group. In comprehensive therapy group, electroacupuncture at temple-three-needle was mainly applied and Fluoxetine Hydrochloride capsule was taken by oral administration; in medication group, Fluoxetine Hydrochloride capsule was applied by oral administration. Functional Independent Measure （FIM） Scale and WHOQOL-BREF evaluation results before and after treatment were compared after 4 weeks treatment. Results Comparing with the FIM scores before treatment, the differences in the two groups were significant （both P0.01）, and the improvement in comprehensive therapy group （74.97±9.52） was superior to that in medication group （66.70±9.23） （P0.01）. Signif icant differences were presented statistically in comparison of index scores of WHOQOL-BREF before and after treatment in two groups （P0.05, P0.01）, and it in comprehensive therapy group was superior to that in medication group （P0.05, P0.01）. Conclusion Activities of daily life and quality of life of post-stroke depression can be significantly improved by electroacupuncture at temple-three-needle and oral administration of Fluoxetine Hydrochloride capsule.
