Objective: This study addressed a case of central post-stroke pain described as right arm painful with coldness and left lateral medullary infarction.Methods: A patient, 71 years old female with medullary infarction, was treated with a Korean herbal medication (BackJun-pill). The improvement of symptoms was evaluated using the Numeral Rating Scale and reports of coldness and pain in the affected areas. We also measured the body temperature difference between the left and right arms using digital infrared thermographic imaging (DITI).Results: After six weeks of treatment with Korean medicine, the patient’s pain and sensation of coldness decreased.Conclusions: This clinical case study suggests that BackJun-pill may be effective for alleviating pain and coldness due to central post-stroke pain.

Background Mild cognitive impairment (MCI) is considered an intermediate phase between normal aging and dementia. As the majority of cases of amnestic MCI (aMCI) progress to Alzheimer’s disease (AD), it is considered the prodromal stage of AD, and a treatment target for prevention of further cognitive decline. However, no medications have been shown to have symptomatic or preventive benefits in MCI. Kami-guibi-tang (KGT) is a traditional herbal formula used in Korean medicine to treat amnesia, which is reported to increase acetylcholine levels via activation of choline acetyltransferase. The objective of this study was to evaluate the efficacy and safety of KGT in patients with aMCI. Methods This study was designed as a single-center, randomized, double-blind, placebo-controlled pilot study. Participants diagnosed with aMCI were randomized to receive either KGT or placebo granules for 24 weeks. The efficacy measure was a change in the Seoul Neuropsychological Screening Battery (SNSB) score. The safety measures included the occurrence of adverse events and abnormalities in vital signs and blood chemistry, electrocardiogram (ECG), and brain magnetic resonance imaging (MRI) findings. Results A total of 16 patients in the KGT group and 14 patients in the placebo group were investigated in the study. The mean score of Clinical Dementia Rating-Sum of Boxes (CDR-SB) significantly improved from 1.53 (0.64) points to 1.13 (0.62) points in the KGT group (p = 0.010), whereas it worsened from 1.61 (0.88) points to 1.75 (0.94) points in the placebo group. There was a significant difference in the CDR-SB scores between the two groups after the intervention (p = 0.045). The total SNSB-D scores and the scores in the memory domain after the treatment were significantly higher than the baseline values in the KGT group, but not in the placebo group. The frequency of adverse events was not significantly different between the two groups, and there were no abnormalities in vital signs or blood test, ECG, and brain MRI findings after the intervention. Conclusions KGT may provide a safe and effective treatment option for patients with aMCI. Further studies with a larger sample size are needed to validate the findings.

Herbal products are the most representative alternative medicine, but most herbal drugs are taken orally and these can cause allergic reactions in the gastrointestinal tract such as food allergies. To confirm whether herbal proteins can cause allergic reaction by binding to human serum immunoglobulin E (IgE), we selected sera from 800 randomized human sera using Allergy-Q tests and investigated the allergenic reactivity of Cnidium officinale (CO) Makinoe extract with positive sera in HMC-1 cells. The proteins derived from CO extract were separated by SDS-PAGE, and identified these proteins using LC–MS/MS. The human sera IgE binding proteins were estimated at the four different predicted proteins such as FAR1-related sequence 5-like protein, a carrier protein, a hypothetical protein, and a predicted protein. The number of positive sera reacted with CO extract was 18 in 800 donor blood (2.25%). In HMC-1 cells, a co-treatment of the positive sera containing CO-specific IgE with CO extract induced synergy effects in ERK/NF-kB activation compared with a sole treatment of human sera, but negative sera did not show a significant change. This results imply that herbal allergens can cause allergic reaction through the crosslinking with human serum IgE, and it may trigger hypersensitivity of body immune system.

Recently, rehabilitative exercise therapies have been described as an important method of overcoming the limitations of the conventional therapies for Parkinson’s disease. The present study aimed to evaluate efficacy and safety of exercise therapies for Parkinson’s disease. Randomized controlled trials that evaluated exercise therapies in patients with Parkinson’s disease until December 2016 were searched for in five electronic databases: PubMed, CENTRAL, EMBASE, OASIS, and CNKI. Eighteen studies (1,144 patients) were included. The overall methodological quality was not high. Patients who underwent exercise therapies exhibited statistically significant improvements in the total UPDRS, UPDRS II and III, Berg Balance Scale, preferred walking speed, and Timed Up and Go Test compared to patients who underwent nonexercise therapies. In comparison to patients who performed regular activity, patients who underwent exercise therapies exhibited statistically significant improvements in the total UPDRS, UPDRS II, and UPDRS III. Exercise therapies were found to be relatively safe. Exercise therapies might promote improvements in the motor symptoms of Parkinson’s disease. However, due to the small number of randomized controlled trials and methodological limitations, we are unable to draw concrete conclusions. Therefore, further studies with better designs will be needed.

Purpose: In Korea, endovascular treatment (EVT) for intracranial aneurysms (IAs) has increased steadily. We conducted a nationwide survey to evaluate the current status of EVT for IAs and to identify treatment preference in the real world.Materials and Methods: A Google online survey was distributed to representative clinicians at hospitals treating IAs, where members of Korean Society of Interventional Neuroradiology (KSIN). The data was collected from October 2017 to December 2017. The responding hospitals were divided into 2 groups (tertiary and non-tertiary hospitals). And variable factors involved in decision making for treatment were evaluated.Results: In total, 73 hospitals (tertiary: 37, non-tertiary: 36) responded to the survey. Most hospitals that responded had over 100 cases of diagnostic angiography (93%) and over 50 cases of EVT for IAs (74%) performed in 2016. The proportion of EVT for ruptured aneurysms in non-tertiary hospitals was significantly higher than tertiary hospitals (49% vs. 9%). The proportion of EVT for unruptured aneurysms at non-tertiary hospitals was significantly higher than tertiary hospitals (66% vs. 44%). Most physicians tended to make decision for treatment on location, shape, and size of unruptured IAs and patients’ age, more than the results from previous clinical trials for unruptured IAs. Although EVT was preferred for older patients (age >70) with unruptured IAs (99%), surgical clipping was still considered as the first treatment of choice for younger patients (age 30 to 50 years) at considerable rates (56%). Over two-thirds of respondents preferred surgical clipping for middle cerebral artery aneurysms, while EVT was preferred initially at other locations.Conclusion: This nationwide survey showed that EVT is considered as the first treatment modality for IAs and there is a discrepancy between current guidelines and real-world practice for decision making of treatment options.

Background: Multiple sclerosis (MS) is a chronic immune-mediated inflammatory disease of the central nervous system that is gradually increasing in prevalence. The etiology of MS remains unknown; however, it is assumed to be caused by a deterioration of autoimmune regulation. Although immunomodulatory agents are a standard treatment option in patients with MS, there is insufficient evidence about their clinical efficacy in symptomatic treatment, and many MS patients resort to complementary and alternative medicine. For this reason, we conducted a scoping review to investigate the current status of the clinical evidence related to traditional East Asian herbal medicine treatment for MS and to inform future research and treatment strategies.Method: A scoping review is an emerging methodology for knowledge synthesis that adopts the Arksey and O'Malley framework. The research question was, “What has been studied about the herbal medicine treatments administered to patients with MS?” Articles published until 2019 were identified in six databases (PubMed, Embase, Cochrane, KoreaMed, NDSL, and OASIS) in March of 2020. Data from the included studies were charted and descriptively analyzed in relation to the study's research questions.Results: Of the 1,445 articles identified, 14 studies were included in this review. Single and serial case reports constituted the majority (42.86%), with 57.14% of studies conducted in China. A total of 20 prescriptions containing 95 herbs were used in the intervention and observational studies. Herbal medicines were effective at improving clinical symptoms of MS and reducing recurrence frequency. The main cause of MS was presumed to be oxidative stress, which enhances inflammation and, consequently, causes neuronal death.Conclusion: Herbal medicines were determined to improve the symptoms of MS and to reduce the frequency of recurrences. This study suggests that herbal medicines are promising and worth pursuing further studies but the state of current evidence is poor. Thus, further, high-quality studies included larger randomized trial are required.

Rationale: Dopamine replacement is currently the standard treatment for restless leg syndrome (RLS); however, various adverse effects are associated with long-term therapy, and the benefits disappear upon discontinuation. To overcome these limitations, interest in traditional East Asian medicine has increased. Patient concerns: A 72-year-old Asian woman originally admitted for an intracerebral hemorrhage presented with complaints of an unpleasant sensation throughout the body that appeared at night. Diagnoses: The patient was diagnosed with chronic persistent RLS based on the 2012 Revised International Restless Leg Syndrome Study Group Diagnostic Criteria. Interventions: The patient was treated with extracts of the traditional herbal medicines Dangguijakyak-san (DS) and Shihogyeji-tang (ST). After 47 days of therapy, all herbal medicines were discontinued, and symptoms had not returned by the last follow-up 244 days after the initial treatment. Outcomes: One week after initiating herbal treatment with DS and ST, the RLS symptoms began to improve, and the total hours of sleep had increased from 2 to 9 hours by day 21, with a Korean version of the international restless legs scale score of 11 points. On day 36, ST was discontinued, given the continued improvement of symptoms. On day 47, symptoms had disappeared (Korean version of the international restless legs scale score: 0), and sleep disturbances caused by RLS had completely resolved. After day 47, DS was also discontinued. There were no adverse effects associated with the administration of DS and ST, and the symptoms had not recurred by the last follow-up on day 244. Lessons: In this case, RLS related symptoms, which had been present for approximately 60 years, were improved using only the traditional herbal medicines DS and ST (without dopamine replacement), and no symptoms recurred for 244 days. This case suggests that if replacement therapy is difficult or not desired, herbal medicinal therapies may be an effective alternative. This also suggests that the effect of herbal medicine on RLS might be semi-permanent. Further investigations, including clinical trials, are needed to confirm these effects.

Background and Aims: This study explores the predictors of early neurological deterioration (END) in patients with vertebrobasilar occlusion (VBO) in both primary endovascular therapy (EVT) and medical management (MM) groups.Methods: Patients diagnosed with VBO from 2010 to 2018 were included. Comparative and multivariate analyses were used to identify predictors of all-cause END in the EVT group, and END due to ischemia progression (END-IP) in the MM group.Results: In 174 patients with VBO, 43 had END. In the primary EVT group (N = 66), 17 all-cause END occurred. Distal basilar occlusion (odds ratio (OR), 14.5 [95% confidence interval (CI), 1.4–154.4]) and reperfusion failure (eTICI < 2b67 (OR, 5.0 [95% CI, 1.3–19.9]) were predictive of END in multivariable analysis. In the MM group (N=108), 17 END-IP occurred. Higher systolic blood pressure (SBP) at presentation (per 10 mmHg increase, OR, 1.5 [95% CI, 1.1–2.0]), stroke onset-to-door time Conclusions: In patients with stroke due to VBO, potential predictors of END can be identified. In the primary EVT group, failure to achieve reperfusion and distal basilar occlusion were associated with all-cause END. In the MM group, higher SBP at presentation, onset-to-door time less than 24 h, incomplete occlusions, larger infarct cores, and poorer collaterals were associated with END-IP.

The Governing Vessel 14 (GV14) (Dazhui) is one of the acupuncture points referred to as “seven acupoints for stroke.” Nevertheless, there is a scarcity of research on the effects of acupuncture treatment at GV14. This study investigated the effects of acupuncture at GV14 on cerebral blood flow (CBF), especially that in the basilar artery (BA) and the middle cerebral arteries (MCA). Sixteen healthy men aged 20 to 29 years were enrolled in this study. CBF velocity and cerebrovascular reactivity (CVR) were measured using transcranial Doppler sonography (TCD). The following were assessed: closed circuit rebreathing- (CCR-) induced carbon dioxide (CO2) reactivity, modified blood flow velocity at 40 mmHg (CV40) on BA and MCAs, blood pressure (BP), and heart rate (HR). Observed results were obtained after comparison with the baseline evaluation. Statistically significant elevations in CO2 reactivity were recorded in the BA (3.28 to 4.70, p < 0.001 ) and MCAs (right: 3.81 to 5.25, p = 0.001 ; left: 3.84 to 5.12, p = 0.005 ) after acupuncture at GV14. The CV40 increased statistically significantly only in the BA (45.49 to 50.41, p = 0.003 ). No change was observed in BP (106.83 to 107.08 (mmHg), p = 0.335 ) and HR (77 to 75 (bpm), p = 0.431 ). Acupuncture at GV14 improved CBF velocity. These results could be explained by the regulation of endothelium-dependent vessel dilation effected by acupuncture. This trial is registered with Korean Clinical Trial Registry (http://cris.nih.go.kr; registration number: KCT0004787).

Background: Despite the rapid advances in medical technology, including endovascular interventions and medications, cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH) is still one of the major threats to the lives of patients with SAH. In East Asian countries, various types of herbal medicines have been used to treat cerebrovascular diseases, including SAH. In this review, we aim to evaluate the efficacy and safety of herbal medicines for the prevention and treatment of CVS after SAH. Methods and analysis: Seven databases will be searched for relevant studies from inception to the present date “June 2020”. Only randomized controlled trials (RCTs) that assess the effect and safety of herbal medicines for the prevention and treatment of CVS after SAH will be included. The methodological quality will be evaluated using the Cochrane risk of bias assessment tool. After selecting the appropriate studies, a meta-analysis of the RCTs will be performed. Results: This study will provide a high-quality synthesis of current evidence of herbal medicines for CVS after SAH. Conclusion: Our systematic review will provide evidence to judge whether herbal medicines are effective interventions for patients with CVS after SAH. Ethics and dissemination: Ethical approval is not required, as this study is based on a review of published research. This review will be published in a peer-reviewed journal and disseminated electronically and in print. Trial registration number: Research registry reviewregistry923.

Background A large-bore aspiration catheter can be employed for recanalization of acute basilar artery occlusion. Here we compare the results of mechanical thrombectomy using a stent retriever (SR) and manual aspiration thrombectomy (MAT) using a large-bore aspiration catheter system as a first-line recanalization method in acute basilar artery occlusion (BAO). Methods The records of 50 patients with acute BAO who underwent mechanical thrombectomy were retrospectively reviewed. Patients were assigned to one of two groups based on the first-line recanalization method. The treatment and clinical outcomes were compared. Results Sixteen (32%) patients were treated with MAT with a large-bore aspiration catheter and 34 (68%) with a SR as the first-line treatment method. The MAT group had a shorter procedure time (28 vs. 65 min; p = 0.001), higher rate of first-pass recanalization (68.8% vs. 38.2%, p = 0.044), and lower median number of passes (1 vs 2; p = 0.008) when compared with the SR group. There was no significant difference in the incidence of any hemorrhagic complication (6.3% vs. 8.8%; p = 0.754) between the groups. However, there were four cases of procedure-related subarachnoid hemorrhage (SAH) in the SR group and one death occurred due to massive hemorrhage. Conclusions Selection of MAT using a large-bore aspiration catheter for acute BAO may be a safe and effective first-line treatment method with higher first-pass recanalization rate and shorter procedure time than SR.

We aimed to investigate the association between Korean medicine (KM) treatment and the risk of Parkinson&rsquo, s Disease (PD) in patients with inflammatory bowel disease (IBD) in South Korea. This study analyzed data from the National Health Insurance Service-Senior cohort in South Korea. The 1816 IBD patients enrolled in the analysis comprised 411 who received only conventional treatment (monotherapy group) and 1405 who received both conventional and KM treatments (integrative therapy group). The risk of PD in patients with IBD was significantly lower in the integrative therapy group than in the monotherapy group after adjusting for confounding variables (adjusted hazard ratio (HR), 0.56, 95% confidence interval (CI) = 0.34&ndash, 0.92). In the mild Charlson Comorbidity Index (CCI) group, the risk of PD in patients with IBD in the integrative therapy group was 0.39 times lower (adjusted HR, 95% CI = 0.20&ndash, 0.77) than that in the monotherapy group. However, there was no significant difference in the risk of PD in patients with IBD between the integrative therapy and monotherapy groups among individuals with severe CCI (adjusted HR, 0.90, 95% CI = 0.41&minus, 1.96). IBD patients are at a decreased risk of PD when they receive integrative therapy. KM treatment may prevent PD in IBD patients.

Background Although herbal medicines (HMs) are widely used worldwide, information concerning their interactions with conventional medicines (CMs) is sparse. In particular, stroke affects a high proportion of elderly people with impaired hepatic and renal function. Stroke is often accompanied by various complications and is commonly treated via the co-administration of HMs and CMs in Asia. Purpose We aimed to investigate the effects of co-administration of HMs and CMs on liver and kidney function in patients with stroke. We estimated the prevalence of drug-induced liver injury (DILI) or herb-induced liver injury (HILI) and drug-induced acute kidney injury (DIAKI) or herb-induced acute kidney injury (HIAKI) in patients co-administered HMs and CMs. Study design This was a retrospective study that reviewed the electronic medical records of 401 patients with stroke in a single hospital. Methods The prevalence of DILI or HILI and types of liver injury was examined according to abnormal increases in liver tests. The probable causality between drug or herb administration and liver injury was assessed using the Roussel Uclaf Causality Assessment Method. In addition, the prevalence of DIAKI or HIAKI was estimated using the Kidney Disease Improving Global Outcomes acute kidney injury stage criteria and related medical records. Results Out of a total of 401 patients, only four (1.0%) developed liver injury. Two cases of DILI (0.5%) and two cases of HILI (0.5%) were reported. Moxifloxacin and ebastine were the CMs that caused hepatotoxicity. Chungpyesagan-tang and Yeoldahanso-tang were the HMs that caused liver toxicity. Even in cases showing severe liver damage, alkaline phosphatase levels remained less than five times the normal value, and liver function test values recovered within 14 days. There were no cases of DIAKI or HIAKI in this cohort. Conclusion These results suggest that if appropriately prescribed by experts, the co-administration of CMs and HMs is safe and does not adversely affect liver and kidney function in patients with stroke. To support these results, further large-scale multicenter prospective studies and toxicological studies based on the interaction between HMs and CMs are warranted.

OBJECTIVE To show whether Danggui Sini plus Wuzhuyu Shengjiang Tang (DSWST) has any transient effect on erythrocyte deformability in normal subjects. METHODS A total of 25 subjects [mean age (27.8 ± 1.8) years] was enrolled in this study. The study was designed as a cross-over trial in which the subjects took part for 2 d. On the first day, blood samples were collected at baseline and 1-2 h after administration of water, whereas, on the second day, instead of water, the subjects were administered DSWST after the baseline blood sampling. The blood samples collected at baseline and after the administration water or DSWST, were examined for erythrocyte deformability. RESULTS The elongation index increased significantly after 2 h (P = 0.009) compared to the baseline after DSWST intake. However, after water intake, there was no significant difference observed. When comparing the percent change of erythrocyte deformability between DSWST and water, we found that after 2 h of administration, DSWST improved erythrocyte deformability significantly compared to water (P CONCLUSION DSWST has a transient effect on erythrocyte deformability in normal subjects.

Introduction. Pharmacoacupuncture is a new acupuncture treatment that stimulates acupuncture points by injecting herbal medicine into them. Recently, pharmacoacupuncture has been widely used in the treatment of idiopathic Parkinson’s disease in traditional East Asian medicine. The purpose of this systematic review is to evaluate the efficacy and safety of pharmacoacupuncture in the treatment of idiopathic Parkinson’s disease. Methods. The following electronic databases were searched for studies published in or before December 2016: Medline, Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, OASIS, and CNKI, without language restriction. The main outcome assessed was the total Unified Parkinson’s Disease Rating Scale (UPDRS) score. The details of the pharmacoacupuncture intervention, such as the herbal medicine and acupuncture points used, were also investigated. Results. From 138 studies, 3 randomized controlled trials were included; the number of patients analyzed was 134. Most of the studies showed considerable methodological flaws. There was heterogeneity of the intervention type and treatment duration in the included studies. Therefore, we could not conduct a meta-analysis. In one study, adjunctive bee venom pharmacoacupuncture therapy significantly improved total UPDRS scores compared with conventional therapy alone. Another study, which used adjunctive Kakkonein pharmacoacupuncture, did not reveal significant improvement compared with conventional therapy alone. A third study reported that Mailuoning pharmacoacupuncture was able to significantly improve the modified Webster Symptom Score when compared with no treatment. Adverse events related to the pharmacoacupuncture were reported in only one case, itching caused by the bee venom. Conclusions. Our findings regarding the efficacy of pharmacoacupuncture as a therapy for idiopathic Parkinson’s disease are currently inconclusive. Further large and rigorous clinical trials are needed.

Various secondary metabolites derived from plants are useful for humans to preserve their health. For this reason, medical herbs have been consumed universally without deep research about the dangerousness of these substance. However, they can produce unexpected adverse reactions in humans. Among these side effects, allergic reactions involving human immunoglobulin E can occur due to antimicrobial or antibacterial substances in plants. Glycyrrhiza uralensis has been prescribed for the treatment of numerous diseases given its multiple types of pharmaceutical efficacy, including its antimicrobial and antibacterial activities. Therefore, we researched whether Glycyrrhiza uralensis, which has antimicrobial ability, can cause allergic reaction in humans. To test the hypothesis devised here, we conducted proteomic level experiments. We utilized SDS-PAGE using a protein extract of Glycyrrhiza uralensis, with Coomassie blue staining to confirm the protein pattern and western blotting to identify Human IgE binding proteins in Glycyrrhiza uralensis. Among the many candidate sera, these methods detected three positive sera. Moreover, an identified protein section with reactivity associated with Human IgE was analyzed by LC-MS/ MS. Our experimental data provide a basis for testing the possibility of Glycyrrhiza uralensis as an allergen by identifying the reactivity between human Immunoglobulin E and proteins of Glycyrrhiza uralensis.

Introduction Arterial elasticity is the significant indicator of atherosclerosis. Recently, the treatment of subclinical atherosclerosis is important for preventing cardiovascular diseases. The purpose of this study was to identify the effect of the Korean herbal medicine, Geiji-Bokryung-Hwan (GBH), on carotid arterial elasticity in healthy male subjects. Methods This study was conducted with a pilot randomized controlled, cross-over design. Subjects were enrolled in Kyung Hee Medical Center visitors, with meeting criteria, and allocated to the two groups; One group received GBH with water, and the other group received only water at the first phase. The measurements were repeated three times at 2 hourly intervals. After one week of wash-out period, the two groups were repeated using the same procedure. Common carotid strain, erythrocyte deformability, carotid intima-media thickness, blood pressure and pulse rate values of each subjects were measured before administration and 2, 4 h after administration. Results Fifteen subjects were enrolled into this study. Common carotid arterial circumference strain after GBH administration showed a significantly different interaction effect as compared to water administration (p Conclusions This preliminary study suggests that GBH could improve vascular endothelial wall function by increasing the common carotid artery elasticity in healthy male subjects.

Post-stroke fatigue (PSF) is one of the most common emotional and mood disorders in stroke survivors. Several studies have suggested associations between PSF and various factors. However, they describe conflicting results. Therefore, this study aimed to evaluate the factors affecting PSF. We retrospectively reviewed the medical records of 178 hospitalized stroke patients. The collected data were compared between the PSF and control groups. To evaluate the association between factors and PSF, regression analysis was conducted. A total of 96 patients (53.9%) were assigned to the PSF group, and 82 patients were assigned to the control group. Age, neurological deficits, cognitive dysfunction, degree of depression, hs-CRP, and ESR differed significantly between the two groups. For both types of stroke, multiple linear regression analyses showed that degree of depression and degree of inflammation were significantly associated with PSF. Through subgroup analysis, multiple linear regression analyses showed that the degree of depression in ischemic and hemorrhagic stroke and the platelet-to-lymphocyte ratio in hemorrhagic stroke had a significant association with PSF. In conclusion, post-stroke depression and degree of inflammation could be clinically significant predictors of PSF in all types of stroke patients. However, larger, prospective studies are required to obtain more concrete results.

Bee venom phospholipase A2 (bvPLA2) has been reported to have therapeutic effects such as neuroprotection, anti-inflammation, anti-nociception, anti-cancer properties, caused by increasing regulatory T cells (Tregs). The mechanism of Tregs modulation by bvPLA2 has been demonstrated by binding with the mannose receptor, CD206 in experimental models of several diseases. However, it remains unknown whether this mechanism can also be applied in human blood. In this study, we collected peripheral blood samples from healthy donors and analyzed the percentages of monocyte-derived dendritic cells with CD206 (CD206+ DCs) before expansion, the proportion of Tregs, and the subpopulations after expansion treated with bvPLA2 or PBS using flow cytometry and the correlations among them. The percentage of Tregs tended to be higher in the bvPLA2 group than in the control group. There were significant positive correlations between the CD206 population in hPBMC and the proportions of Tregs treated with bvPLA2, especially in the Treg fold change comparing the increase ratio of Tregs in bvPLA2 and in PBS. These findings indicate that bvPLA2 increased the proportion of Tregs in healthy human peripheral blood and the number of CD206+ DCs could be a predictor of the bvPLA2 response of different individuals.

BACKGROUND AND PURPOSE: There is an uncertainty about the association between intracranial aneurysms and aortic dissection. We aimed to determine the prevalence of intracranial aneurysms in patients with aortic dissection and evaluate the independent risk factors for the presence of intracranial aneurysms in these patients. MATERIALS AND METHODS: Seventy-one patients with a confirmed aortic dissection who underwent additional brain imaging were enrolled as the aortic dissection group, and 2118 healthy individuals with brain imaging, as controls. Demographic data were obtained from their medical records, including age, sex, comorbidities, and arch vessel involvement of aortic dissection. Two readers reviewed all brain images independently regarding the presence, morphology, size, and location of intracranial aneurysms. Baseline characteristics were compared between the aortic dissection group and controls by propensity score matching, and logistic regression analysis was performed for independent risk factors for the presence of intracranial aneurysms. RESULTS: The prevalence of intracranial aneurysms was 12.96% in the aortic dissection group and 1.85% in controls ( P = .022). The mean diameter of intracranial aneurysms was significantly larger in the aortic dissection group (5.79 ± 3.26 mm in aortic dissection versus 3.04 ± 1.57 mm in controls; P = .008), and intracranial aneurysms of >7 mm were also more common in the aortic dissection group (28.6% in aortic dissection versus 5.3% in controls, P = .003). On multivariate analysis, arch vessel involvement of aortic dissection was an independent risk factor for the presence of intracranial aneurysms (odds ratio, 6.246; 95% confidence interval, 1.472–26.50; P = .013). CONCLUSIONS: Patients with aortic dissection have a high prevalence of intracranial aneurysms, and selective screening for brain vessels could be considered in these patients with arch vessel involvement. A further prospective study is needed to demonstrate a substantial prevalence of intracranial aneurysms.

We investigated whether the CSF cleft sign on ADC maps is beneficial for differentiating extra-axial tumors from intra-axial tumors. Seventy-seven intracranial tumor patients were reviewed. Visual grades of CSF cleft sign on T2WI and ADC were compared. The diagnostic performance of CSF cleft sign using ADC plus T2WI was compared with that using T2WI alone. A CSF cleft was more easily visualized on ADC (P

Introduction Moxibustion is the burning of mugwort used to stimulate acupuncture points on the skin. In traditional East-Asian medicine, moxibustion is often used as a non-drug treatment for idiopathic Parkinson's disease (IPD). The aim of this systematic review was to evaluate the effectiveness and safety of moxibustion therapy to treat IPD. Methods The following electronic databases were searched for studies published in or before December 2016: Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, OASIS (Korean database), and CNKI (Chinese database). Two researchers conducted the data extraction and risk of bias assessments. Results From the results, a total of 10 studies (644 IPD patients) were included in this review. Overall methodological quality was not high and all studies included small numbers of participants which could not ensure the rigor of the synthesized evidence. There was a considerable clinical heterogeneity in terms of patient’s population, moxibustion types and control group interventions. Compared with control group, moxibustion did not show significant difference in the overall effectiveness ratio (RR 1.20, 95% CI [1.00, 1.44]). About the total unified Parkinson’s disease rating scale (UPDRS) score, however, there was significant difference between moxibustion and control interventions (MD −8.75, 95% CI [−12.54, −4.95]). Adverse events related to moxibustion treatment were not reported in most of the studies. Conclusions Evidence on the benefit and harm of moxibustion therapy for IPD was not conclusive due to methodological problems and small sample sizes among the included studies. More rigorous clinical studies will be necessary in future.

We evaluated the best methods for predicting various infarct core thresholds for endovascular treatment of ischemic stroke using parameters obtained by multiphase computed tomographic angiography (mCTA). Consecutive patients evaluated for endovascular treatment who concomitantly underwent mCTA and stroke magnetic resonance imaging (MRI) were analyzed. The ability of CTA-based collaterals (single-phase [sCTAc] and multiphase [mCTAc]) and ASPECTS or their combined interpretation for the selection of patients with cores of

Background: Buyang Huanwu Tang (BHT) is a well-known herbal complex used for stroke treatment and has been used mainly during post-stroke rehabilitation in East Asia. In this review, we aim to evaluate the efficacy and safety of BHT as a treatment for post-stroke fatigue (PSF). Methods: Eight databases will be searched for relevant studies from inception to the present date. We will include randomized controlled trials (RCTs), which assess the effect and safety of BHT for the treatment of PSF. The methodological qualities, including the risk of bias (RoB), will be evaluated using the Cochrane RoB assessment tool. After screening the studies, a meta-analysis of the RCTs will be done. Results: This study will provide high-quality synthesis of current evidence of BHT for PSF. Conclusion: The conclusion of our systematic review will provide evidence to judge whether BHT is an effective intervention for patients with PSF. Ethics and dissemination: Ethical approval is not required, as this study is based on the review of published research. This review will be published in a peer-reviewed journal and disseminated both electronically and in print. Trial registration number: PROSPERO CRD42019130178.

Objectives: To determine whether acupuncture at GB34 affects cerebral blood flow (CBF) via the anterior cerebral arteries (ACAs) and middle cerebral arteries (MCAs). Methods: This study included 10 healthy young male volunteers. CBF velocity and cerebrovascular reactivity (CVR) were measured using transcranial Doppler sonography (TCD). The changes in hyperventilation-induced carbon dioxide (CO2) reactivity and modified blood flow velocity at 40 mm Hg (CV40) were observed for both ACAs and MCAs before and after GB34 acupuncture treatment. Blood pressure and heart rate were also measured before and after GB34 acupuncture treatment. Results: The CO2 reactivity of the ipsilateral MCA significantly increased after GB34 acupuncture treatment, compared with that at baseline (P=0.007). In contrast, the CO2 reactivity of both ACAs and the contralateral MCA remained unchanged. The CV40 of both ACAs and MCAs did not change after GB34 acupuncture treatment and neither did the mean arterial blood pressure and heart rate. Conclusions: GB34 acupuncture treatment increased CO2 reactivity specifically in the ipsilateral MCA, but had no effect on either the ACAs or the contralateral MCA. These data suggest that GB34 acupuncture treatment improves the vasodilatory potential of the cerebral vasculature to compensate for fluctuations caused by changes in external conditions and could potentially be useful for the treatment of disorders of the ipsilateral MCA circulation.

Recently, the herbal medicine Ukgansan (Yigansan in China, Yokukansan in Japan) was reported to be effective in the management of movement disorders. We report the case of a 62-year-old woman with herpes simplex encephalitis exhibiting atypical abnormal movements in the chronic stage. While controlling the abnormal movements with haloperidol, an antipsychotic agent, we prescribed Ukgansan-gami, an extract of a variant of Ukgansan, at a dose of 12 g/day to prevent the recurrence of abnormal movements and allow for the discontinuation of haloperidol. The patient was successfully treated with Ukgansan-gami, with no further recurrence of symptoms, making the use of haloperidol no longer necessary. The potential mechanism of action of Ukgansan involves the inhibition of nervous system hyperexcitability through the suppression of glutamate sodium channels, as well as attenuation of hypermotility through serotonin regulation. The present case suggests that herbal medicine therapy was likely to be an alternative to antipsychotics.

Objectives: Basilar artery trunk aneurysms (BTAs) are a rare pathology and difficult to treat. We present our experience regarding angiographic results and clinical outcomes for 16 BTAs treated by reconstructive endovascular treatment (EVT) using stent or balloon. Methods: Between January 2003 and December 2014, 15 patients (mean age, 58.6 years; 11 males) with 16 BTAs were enrolled. Clinical manifestation, outcomes and procedural complications were evaluated retrospectively, and follow-up angiography was performed 12 and 24 months after procedure. Results: Subarachnoid hemorrhage (SAH) developed in seven aneurysms and nine were found incidentally. In one case, SAH followed by acute infarction on pons. The location of the aneurysms was the pure basilar artery (BA) trunk in 13 and the junction of the BA and the superior cerebellar artery in 3. Reconstructive EVT was technically successful in 15 aneurysms (93.8%) and failed in one due to the difficulty of vascular access. Stent/balloon-assisted coiling was performed in 13 aneurysms and sole stent therapy in two aneurysms. One patient had periprocedural complication of acute in-stent thrombosis. All treated patients had no symptoms with the usual activities except three patients, who died from myocardial infarction, aneurysmal rebleeding, and cerebellar infarction. Angiographic follow-up was performed in nine aneurysms; three aneurysms were recanalized (33.3%) and six aneurysms had no interval change (66.7%). There was no significant event during the follow-up period (mean, 23.5 months). Conclusion: In the treatment of BTAs, reconstructive EVT may provide a feasible and safe option to microsurgery.

Background. Various sham acupuncture devices have been developed and used in studies on acupuncture. However, there is controversy on whether these devices act as an appropriate placebo or control. In particular, validation of sham acupuncture has only been performed in studies involving healthy individuals. In this regard, questions on the suitability of various sham acupuncture treatments in studies involving disease treatment remain unanswered. Therefore, in this study, we would like to investigate the most appropriate sham acupuncture in the research on treatment of hemiplegic stroke. Methods. The proposed study is a single-center, prospective, randomized sequence, participant- and assessor-blinded trial with four parallel arms. A total of 90 participants will be randomly assigned to Group 1, Group 2, Group 3, or Group 4 in a 1 : 1 : 1 : 1 ratio. All groups will be treated with Quchi (LI11) for 20 minutes. Group 1 will be treated with verum acupuncture; Group 2, with Park Sham Device; Group 3, with Streitberger’s needle; and Group 4, with insertion- and removal-type devices. Participants will undergo one treatment session. The primary outcome is Bang’s blinding index. Secondary outcomes are the “Discomfort caused by acupuncture therapy” questionnaire and the Massachusetts General Hospital Acupuncture Sensation Scale index. Immediately after the procedure, all participants will also be monitored for adverse events. Discussion. This study will help identify the optimal sham acupuncture device that can be used for clinical studies on acupuncture treatment in hemiplegic stroke patients. This trial is registered with KCT0002622.

Background and purpose In Asian countries, herbal medicines have been used to treat Chronic subdural hematoma (CSDH) as an adjunctive therapy. This review aims to evaluate the efficacy and safety of herbal medicine on treating CSDH and preventing recurrent CSDH. Methods A literature search was conducted on PubMed, CENTRAL, Scopus, CiNii, KTKP, NDSL, OASIS, and CNKI for randomized controlled trials that evaluated the effects of herbal medicines on CSDH. Results Seven studies (n = 646) were included. The overall methodological quality of these studies was low. In the herbal group, the meta-analysis indicated statistically significant improvements in the total effective rate and recurrence rate as compared with those in the non-herbal group. Herbal treatments were found to be relatively safe. Conclusion Herbal medicines might be efficacious in the management of CSDH and prevent its recurrence. Further rigorous studies will have to be conducted in order to make more definite conclusions.

Allergy is nearly always triggered by protein molecules and the majority of individuals with documented immunologic reaction to foods or plants IgE reactions. However, proteins derived from herbal medicine act as an allergen is unknown. In this study, we aimed to confirm if herbal medicine, Astragalus membranaceus, at proteomic level may contain to trigger the immunoreactivity of IgE. If it does, what components of protein molecules in herbal medicine, Astragalus membranaceus, is react to a binding IgE. In order to resolve this hypothesis, we performed proteomic tools, SDS-PAGE stained coomassie blue and identified protein by LC-MS/MS. Also, we tested plasma IgE reactivity on an isolated protein of Astragalus membranaceus using western blot of human IgE and enzyme immunoassay panel, Allergy-Q test in 400 patients. Through the described performances, we could select four sera of positive candidate and identify Astragalus membranaceus IgE binding proteins. Our data suggested that herbal medicine, Astragalus membranaceus was possible to act an allergen by identify IgE binding protein with isolated protein of Astragalus membranaceus.

Introduction Migraine is a common and disabling primary headache disorder. Cupping is a traditional medical treatment used in several societies in East Asia and it is frequently used for controlling pain including migraine. There have been no systematic reviews on the treatment effects of cupping on migraine. Furthermore, related studies have had many limitations, making it unclear whether cupping intervention is beneficial for migraine. We propose to conduct a systematic review and meta-analysis to consider the evidence related to the effect of cupping on migraine. Methods We developed a protocol describing the essential reporting items based on the PRISMA for systematic review protocols 2015 (PRISMA-P 2015) (Registration number: CRD42017054979). We will search eight databases and include data from prospective randomized controlled clinical trials or quasi-randomized controlled trials that used cupping interventions for the treatment of migraine. The risk of bias will be assessed with the “Risk of bias” tool from the Cochrane Handbook. Using improved effectiveness and the change in headache pain intensity as graded on the visual analogue scale as the primary outcomes, we will compare these outcomes between the cupping intervention and control groups. Conclusion There have been no systematic reviews of cupping therapy for migraine headaches to date. This systematic review will assess the effectiveness and safety of cupping therapy for migraine. This systematic review will inform and help healthcare practitioners to treat migraine and will be disseminated electronically and in print in a peer-reviewed journal.

Background: Post-stroke dysphagia (PSD) requires effective treatment as it may cause aspiration pneumonia, dehydration, or malnutritution, which can increase the length of hospital stay as well as mortality. In the field of stroke, electroacupuncture (EA) has been widely used, and a number of clinical research papers have been published regarding its effects. This systematic review aims to evaluate the effectiveness of EA for the treatment of PSD. Methods: Randomized controlled trials evaluating the use of EA in PSD will be included in this meta-analysis. The following electronic databases will be searched from inception to July 31, 2020, using terms relating to EA and PSD: PubMed, the Cochrane Library, the Excerpta Medica Database, China National Knowledge Infrastructure, the Korean Medical Database, KoreaMed, the National Digital Science Library, and the Oriental Medicine Advanced Searching Integrated System. Two reviewers will independently search these databases, select studies for inclusion, and evaluate the quality of the studies. Methodological quality will be assessed using the Cochrane Handbook for Systematic Reviews of Interventions (version 6.0). The primary outcome will be the total effective rate; secondary outcomes will include results of other assessments of dysphagia such as the water drinking test scale and videofluoroscopic swallowing study. We will also investigate the number and severity of adverse events. The Cochrane Review Manager (RevMan) software (version 5.3.5) will be employed to assess bias risk, data integration risk, and meta-analysis risk. Mean difference and standardized mean difference will be used to represent continuous data, while risk ratios will be used for pooled binary data. Results: This study will provide a comprehensive review and evaluation of the available evidence regarding the efficacy and safety of EA as a treatment for PSD. Conclusion: This study will clarify whether EA could be an effective and safe treatment for PSD.

Background Alzheimer disease (AD) is a leading progressive neurodegenerative disease worldwide, but treating it is challenging in clinical practice. This review is aimed at evaluating the efficacy and safety of herbal medicine for treating AD.

Background It is important to manage inflammation after craniotomy. It may be prudent to reduce the excessive usage of antibiotics and to add supplementary treatments like acupuncture, which would be effective and safe. However, there are only a few studies available to date on the effects of acupuncture on anti-inflammatory response after craniotomy. The aim of this study was to explore the anti-inflammatory effects of acupuncture in patients after a craniotomy. Methods This study was a single-center, prospective, open-label, controlled trial. Forty-four subjects who underwent craniotomy for an unruptured aneurysm, facial spasm, or brain tumor were allocated to either an acupuncture group or a control group. Both groups received postoperative routine care in the Department of Neurosurgery. The subjects in the acupuncture group also received a total of 6 acupuncture treatments sessions within 8 days after craniotomy. Acupuncture treatments included acupuncture, electroacupuncture, and intradermal acupuncture. The serum interleukin (IL)-1β and IL-6, tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and erythrocyte sedimentation rate levels were assessed four times within 7 days after surgery. The presence of fever, use of additional antibiotics, presence of infection including pneumonia or urinary tract infection, and safety were also reviewed. Results The IL-1β levels of subjects who underwent aneurysmal clipping were significantly lower in the acupuncture group (P = .02). TNF-α levels of subjects who underwent aneurysmal clipping at the seventh postoperative day were also significantly lower in the acupuncture group (P = .03). Six cases of fever of unknown origin were observed in the control group, while none were seen in the acupuncture group, revealing that the incidence of fever was significantly lower in the acupuncture group (P = .02). No adverse events occurred during the trial. Conclusion Acupuncture showed a possibility of alleviating inflammation by attenuating the levels of proinflammatory cytokines and significantly reduced the incidence of fever of unknown origin in patients after craniotomy. Acupuncture would be suitable as an adjunctive therapy to alleviate inflammation after craniotomy.
