RESUMEN
BACKGROUND: Parkinson's disease (PD) is one of the most prevalent neurodegenerative diseases in world. As some psychiatric symptoms degrade the quality of life of patients with PD, a novel alternative non-pharmacological treatment is required. Acupuncture appears to be an effective and safe treatment for PD. The emotional freedom technique (EFT) is a type of psychological therapy that alleviates psychiatric symptoms by stimulating acupoints. In this study, we will compare the efficacy and safety of a combination of the EFT and acupuncture and acupuncture alone. METHODS: This study is a randomized, assessor-blind, parallel-group clinical trial. Eighty participants will be equally divided into experimental and control groups. Each participant will receive a total of 24 interventions over 12 weeks. The experimental group will receive EFT combined with acupuncture and the control group will receive acupuncture alone. The primary outcome is the change in the Beck Depression Inventory score from baseline to 12 weeks, and the secondary outcomes include change in the following variables: Beck Depression Inventory, Parkinson's disease sleep scale, State-Trait Anxiety Inventory, the Korean version of the Fatigue, Resistance, Ambulation, Illnesses, and Loss of weight questionnaire scale, and unified Parkinson's disease rating scale III and exercises. DISCUSSION: Acupuncture is a safe and effective treatment for motor and nonmotor symptoms in PD, and EFT appears to be safe and effective for a variety of psychiatric symptoms. In this study, we will investigate the potential of EFT combined with acupuncture to improve psychiatric symptoms in PD.

OBJECTIVE: The objective of this review is to provide a modern definition and identify potential biomarkers of blood stasis in cardio- and cerebrovascular diseases by mapping, comparing, and combining Eastern and Western concepts. INTRODUCTION: Blood stasis is a pathological concept found in both Eastern and Western medical literature. In traditional East Asian medicine, blood stasis is a differential syndrome characterized by stagnant blood flow in various parts of the body. Similarly, in Western medicine, various diseases, especially cardio- and cerebrovascular diseases, are known to be accompanied by blood stasis. Numerous scientific studies on blood stasis have been conducted over the last decade, and there is a need to synthesize those results. INCLUSION CRITERIA: We will use the keywords "blood stasis," "blood stagnation," "blood stagnant," and "blood congestion" in 3 electronic databases: PubMed, Cochrane CENTRAL, and Google Scholar. In addition, we will use the keywords "ì´í" and "íì´" in 4 Korean electronic databases (ie, NDSL, OASIS, KISS, and DBpia). Peer-reviewed articles published from 2010 to the present that focus on blood stasis in cardio- and cerebrovascular diseases in human subjects according to the International Classification of Diseases 11 th revision categories BA00-BE2Z, 8B00-8B2Z, 8E64, and 8E65 will be included. Reviews, opinion articles, in vivo, in vitro, and in silico preclinical studies will be excluded. METHODS: We will follow the frameworks by Arksey and O'Malley and Levac et al. as well as JBI guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews. Two reviewers will independently search and screen titles and abstracts followed by full-text screening of eligible studies. If there are discrepancies between the 2 reviewers, a third reviewer will be consulted to make the final decision. We will use descriptive narrative, tabular, and graphical displays, and content analysis to present the results. SCOPING REVIEW REGISTRATION: Open Science Framework https://osf.io/gv4ym.

Jaeumgeonbi-Tang (JGT), a traditional herbal medicine, has been used to treat dizziness and vertigo in Korea and China for hundreds of years. The purpose of this study was to evaluate the pharmacological properties of JGT in chronic subjective dizziness (CSD) patients. A randomized, double-blind, parallel-group and placebo-controlled trial was performed with a total of 50 CSD patients. The patients were randomly assigned to one of two groups: JGT or placebo (n = 25 for each). All participants received the treatment (placebo or JGT, 24 g/day) for 4 weeks. We analyzed the serum levels of oxidative stressors, antioxidants, and stress hormones. Serum levels of lipid peroxidation, but not nitric oxide, were significantly decreased in the JGT group. JGT not only prevented the decline of serum total glutathione contents and total antioxidant capacity, but it also increased superoxide dismutase and catalase activities. Serum levels of stress hormones including cortisol, adrenaline, and serotonin were notably normalized by JGT treatment, but noradrenaline levels were not affected. Regarding the safety and tolerability of JGT, we found no allergic, adverse, or side effects in any of the participants. JGT showed beneficial effects on CSD patients by improving redox status and balancing psycho-emotional stress hormones.
RESUMEN
Nuclear receptor-related 1 protein (Nurr1) is a nuclear hormone receptor that protects dopaminergic neurons and is a promising therapeutic target for Parkinson's disease (PD). Parkinson's disease is a neurodegenerative disorder caused by the destruction of dopaminergic neurons in the substantia nigra pars compacta (SNpc), and the long-term use of conventional dopamine replacement therapies causes many side effects, highlighting the need for new treatments such as complementary and alternative medicine. Ukgansan has been used in East Asia to treat neurological disorders, including neurodegenerative diseases, and has been reported to have strong effects in treating patients with PD. In addition, recent studies have reported that Ukgansan has a neuroprotective potential. However, there are no detailed studies on the mechanism of action of Nurr1. Thus, unlike previous studies, we focused on the Nurr1 pathways. We confirmed neurotoxicity and apoptosis signaling in the differentiated PC12 cells. In addition, to confirm the protective effect of Ukgansan, we conducted behavioral tests (motor coordination and postural balance, and bradykinesia) and tyrosine hydroxylase immunohistochemistry in both the SNpc and striatum. Specifically, this study demonstrated the effect of Ukgansan in protecting dopaminergic neurons and increasing Nurr1 involved in maintaining dopamine levels by activating Nurr1 expression in MPTP-induced PC12 cells and a mouse model of PD. In this mechanism, the loss of dopaminergic neurons and dopamine depletion were suppressed, and motor impairment caused by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine toxicity was improved. These results provide evidence that Ukgansan ameliorates PD's motor symptoms and progression.
RESUMEN
Yukmijihwang-Tang is widely used in traditional Korean medicine to treat age-related disorders. In the present study, we re-prescribed Gami-Yukmijihwang-Tang (YJT), which is slightly modified from Yukmijihwang-Tang by adding more medicinal plants to evaluate its pharmacological effects on underlying mechanisms against repeated lipopolysaccharide (LPS)-injection-induced neuroinflammation in the hippocampus regions. C57BL/6J male mice (16-24 weeks old) were divided into six groups: (1) the control group (DW with 0.9% saline injection), (2) LPS group (DW with LPS injection), YJT groups ((3) 100, (4) 200, or (5) 400 mg/kg of YJT with LPS injection), and (6) glutathione (GSH) group (100 mg/kg of GSH with LPS injection), respectively. Mice were orally administrated with various doses of YJT or glutathione (GSH) for the first five days. Neuroinflammation in the hippocampus region was induced by repeated injection of LPS during the last three days. As predicted, LPS not only increased oxidative stress-related markers including malondialdehyde, 4-hydroxynonenal, nitrotryptophan, and hydrogen peroxide, but also drastically enhanced inflammatory reactions including nitric oxide, inducible nitric oxide synthase, p65, and toll-like receptor 4, respectively. YJT administration, on the other hand, notably decreased the above pathological alterations by enhancement of antioxidant capacities such as superoxide dismutase and catalase activities. To explain the underlying pharmacological actions of YJT, we focused on a representative epigenetic regulator, a nicotinamide adenine dinucleotide + (NAD+)-dependent chromatin enzyme, Sirtuin 6 (Sirt6). Neuroinflammation in hippocampus regions depleted Sirt6 at the protein level and this alteration directly affected the nuclear factor erythroid 2-related factor (Nrf2)/hemeoxygenase (HO)-1 signaling pathway in the LPS group; however, YJT significantly recovered the Sirt6 protein levels, and it could recover the abnormal status of Nrf2/HO-1 signaling pathways in the hippocampus regions. Additionally, Sirt6 led to the up-regulation of GSH sub-enzymes of mRNA expression and protein levels of total GSH content. These findings suggest that YJT can protect against LPS-induced neuroinflammation and oxidative stress by regulating the Sirt6-related pathways and normalizing the GSH redox cycle.
RESUMEN
Mild cognitive impairment (MCI) is a precursor to Alzheimer's disease. It is imperative to develop a proper treatment for this neurological disease in the aging society. This observational study investigated the effects of acupuncture therapy on MCI patients. Eleven healthy individuals and eleven MCI patients were recruited for this study. Oxy- and deoxy-hemoglobin signals in the prefrontal cortex during working-memory tasks were monitored using functional near-infrared spectroscopy. Before acupuncture treatment, working-memory experiments were conducted for healthy control (HC) and MCI groups (MCI-0), followed by 24 sessions of acupuncture for the MCI group. The acupuncture sessions were initially carried out for 6 weeks (two sessions per week), after which experiments were performed again on the MCI group (MCI-1). This was followed by another set of acupuncture sessions that also lasted for 6 weeks, after which the experiments were repeated on the MCI group (MCI-2). Statistical analyses of the signals and classifications based on activation maps as well as temporal features were performed. The highest classification accuracies obtained using binary connectivity maps were 85.7% HC vs. MCI-0, 69.5% HC vs. MCI-1, and 61.69% HC vs. MCI-2. The classification accuracies using the temporal features mean from 5 seconds to 28 seconds and maximum (i.e, max(5:28 seconds)) values were 60.6% HC vs. MCI-0, 56.9% HC vs. MCI-1, and 56.4% HC vs. MCI-2. The results reveal that there was a change in the temporal characteristics of the hemodynamic response of MCI patients due to acupuncture. This was reflected by a reduction in the classification accuracy after the therapy, indicating that the patients' brain responses improved and became comparable to those of healthy subjects. A similar trend was reflected in the classification using the image feature. These results indicate that acupuncture can be used for the treatment of MCI patients.
RESUMEN
BACKGROUND: Herbal medicine is widely recommended to treat viral infectious diseases. Over 123,000,000 individuals have been infected with the coronavirus since a worldwide pandemic was declared in March 2020. We conducted this research to confirm the potential of herbal medicine as a treatment for coronavirus. METHODS: We infected the A549 cell line with betacoronavirus OC43 and then treated it with 100 µg/mL Hyunggaeyungyo-tang (HGYGT) or distilled water with a control of HGYGT. We measured the mRNA expression levels of proinflammatory cytokines and interferon stimulated genes (ISGs) to confirm the effectiveness of HGYGT upon coronavirus infection. RESULTS: We found that the effects of HYGYT decrease the expression level of pPKR, peIF2α, IFI6, IFI44, IFI44L, IFI27, IRF7, OASL, and ISG15 when administered to cells with coronavirus infection. The expressions of IL-1, TNF-α, COX-2, NF-κB, iNOS, and IKK mRNA were also significantly decreased in the HGYGT group than in the control group. CONCLUSION: Through the reduction of the amount of coronavirus RNA, our research indicates that HGYGT has antiviral effects. The reduction of IKK and iNOS mRNA levels indicate that HGYGT reduces coronavirus RNA expression and may inhibit the replication of coronavirus by acting on NF-kB/Rel pathways to protect oxidative injury. In addition, decreases in mRNA expression levels of proinflammatory cytokines indicate that the HGYGT may relieve the symptoms of coronavirus infections.
RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: Yuk-Mi-Jihwang-Tang (YJT) has been popularly prescribed to treat aging related disorders over than hundreds of years in East Asia countries. AIM OF THE STUDY: To investigate possible modulatory actions of YJT on chronic restraint stress (CRS)-induced neurodegeneration on hippocampus neuronal injuries. MATERIALS AND METHODS: Mice were orally administered with YJT (100, 200, or 400 mg/kg) or ascorbic acid (100 mg/kg) before 4 h of stress for 28 days. Morris water maze task was completed from day 24th to 28th, and stress hormones and biochemical analyzes were measured. RESULTS: Four weeks of the CRS abnormally affected memory impairments by measurement of escape latency and time spent in the target quadrant. Additionally, neurotransmitters were also drastically altered in serum or hippocampus protein levels by CRS. Gene expressions for 5-hydroxytryptamine (5-HT) receptor, 5-HT-transport, and tryptophan hydroxylase were also altered, whereas YJT led to normalize the above alterations. Additionally, YJT also beneficially worked on endogenous redox system as well as inflammatory reactions in the hippocampal neurons. We observed that hippocampal excitotoxicity was induced by CRS which were evidenced by depletion of phosphor-cAMP response element-binding protein, brain-derived neurotrophic factor, nuclear factor erythroid-2-related factor 2, heme oxygenase-1 and abnormally increases of acetylcholine esterase activities in hippocampus protein levels; however, YJT considerably improved the above pathological conditions. CONCLUSIONS: Our findings supported YJT enhance memory function via regulation of hippocampal excitotoxicity-derived memory impairment, stress hormone, and endogenous redox, respectively.

Acupuncture therapy (AT) is a non-pharmacological method of treatment that has been applied to various neurological diseases. However, studies on its longitudinal effect on the neural mechanisms of patients with mild cognitive impairment (MCI) for treatment purposes are still lacking in the literature. In this clinical study, we assess the longitudinal effects of ATs on MCI patients using two methods: (i) Montreal Cognitive Assessment test (MoCA-K, Korean version), and (ii) the hemodynamic response (HR) analyses using functional near-infrared spectroscopy (fNIRS). fNIRS signals of a working memory (WM) task were acquired from the prefrontal cortex. Twelve elderly MCI patients and 12 healthy people were recruited as target and healthy control (HC) groups, respectively. Each group went through an fNIRS scanning procedure three times: The initial data were obtained without any ATs, and subsequently a total of 24 AT sessions were conducted for MCI patients (i.e., MCI-0: the data prior to ATs, MCI-1: after 12 sessions of ATs for 6 weeks, MCI-2: another 12 sessions of ATs for 6 weeks). The mean HR responses of all MCI-0-2 cases were lower than those of HCs. To compare the effects of AT on MCI patients, MoCA-K results, temporal HR data, and spatial activation patterns (i.e., t-maps) were examined. In addition, analyses of functional connectivity (FC) and graph theory upon WM tasks were conducted. With ATs, (i) the averaged MoCA-K test scores were improved (MCI-1, p = 0.002; MCI-2, p = 2.9e -4); (ii) the mean HR response of WM tasks was increased (p < 0.001); and (iii) the t-maps of MCI-1 and MCI-2 were enhanced. Furthermore, an increased FC in the prefrontal cortex in both MCI-1/MCI-2 cases in comparison to MCI-0 was obtained (p < 0.01), and an increasing trend in the graph theory parameters was observed. All these findings reveal that ATs have a positive impact on improving the cognitive function of MCI patients. In conclusion, ATs can be used as a therapeutic tool for MCI patients as a non-pharmacological method (Clinical trial registration number: KCT 0002451 https://cris.nih.go.kr/cris/en/).
RESUMEN
BACKGROUND: Almost half of mild cognitive impairment (MCI) patients progress to dementia, which is associated with decreased quality of life and obstacles to independent living. Relevant management is expected to prevent MCI patients from progressing to dementia. In recent years, electroacupuncture (EA) has been used to treat various kinds of neurological disorders including MCI. This study evaluates the use of EA for MCI patients to increase cognitive function through a comparison with Western medications. METHODS: Randomized controlled trials (RCT) or systematical reviews (SR) of EA versus Western medications for MCI were searched using the following 10 databases: Pubmed, Cochrane Library, CINAHL, EMBASE, China National Knowledge Infrastructure (CNKI), National Digital Science Library (NDSL), Journal of Oriental Neuropsychiatry (JON), Korean Medical Database (KMBASE), KoreaMed, and OASIS, from October 2007 to August 2017, without language restriction. A methodological quality assessment of RCTs or SRs that met inclusion criteria was conducted using Cochrane Risk of bias (RoB) tool and a meta-analysis by RevMan (Review Manager) 5.3.5 version of Cochrane collaboration. RESULTS: Five RCTs with 257 patients met inclusion criteria and those were randomly divided into two groups: the EA group (n = 103) and Western medications group (n = 154). The methodological quality of the included studies showed high risk or/and unclear of risk of bias. The meta-analysis of five studies reported that the EA group was better than the Western medications group, improving the Mini Mental State Examination (MMSE) score by 0.65 [95% CI 0.28~1.01] higher mean difference, Montreal Cognitive Assessment (MoCA) score by 0.66 [95% CI 0.00~1.32] higher mean difference. Adverse effects were not reported in the selected studies. CONCLUSION: Electroacupuncture was an effective treatment for MCI patients by improving cognitive function. However, the included studies presented a low methodological quality and no adverse effects were reported. Thus, further comprehensive studies with a design in depth are needed to derive significant results.

OBJECTIVE: To evaluate the effectiveness and safety of treatment with thread-embedding acupuncture (TEA) using polydioxanone in addition to usual care for patients with chronic nonspecific neck pain (CNP) compared with treatment with usual care alone. METHODS: A single-center, assessor-blinded, two-armed randomized controlled trial was performed. One hundred and six outpatients with CNP were randomly allocated into the TEA plus usual care (TU) group or the usual care (UC) group in a 1:1 ratio. TEA treatments in the neck region were provided once a week for 4 weeks, and usual care, as needed, was allowed. The primary outcome was the mean Neck Pain and Disability Scale (NPDS) score. Secondary outcomes included clinical relevance measured by using the clinically important difference (CID), pressure pain threshold (PPT), Hospital Anxiety and Depression Scale (HADS), EuroQol-5 Dimension (EQ-5D), and patient global impression of change (PGIC). Participants were assessed at baseline and at weeks 3, 5, and 9. Statistical analyses included analysis of covariance with baseline score as a covariate. RESULTS: The TU group showed significant improvement in NPDS scores compared with the UC group (adjusted group difference, week 5: 13.74 [95% confidence interval: 7.57-19.90]; p < 0.0001 and week 9: 17.46 [11.15-23.76]; p < 0.0001). The proportion of patients with a decrease on the NPDS score of ≥11.5 points (minimal CID) was significantly higher in the TU group at weeks 5 and 9 than in the UC group. At weeks 5 and 9, significant differences were observed on the anxiety/depression subscale of HADS, EQ-5D, and PGIC between the two groups, but not the PPTs at three sites. Temporary stiffness was observed after TEA treatment, but no serious adverse events occurred. CONCLUSIONS: The results suggest that polydioxanone TEA is a safe and clinically beneficial adjunctive treatment for patients with CNP.

BACKGROUND: Currently, there is no clearly established therapy to treat mild cognitive impairment (MCI); consequently, alternative therapies, such as acupuncture, have been attempted. In many clinical studies, the potential benefits of acupuncture for cognitive improvement have been identified in clinical outcomes; however, the mechanism remains unclear. Accordingly, this study aims to investigate the therapeutic mechanism of acupuncture therapy using functional near-infrared spectroscopy and its feasibility in treating individuals with impaired cognitive function. METHODS: This study is designed to be a prospective, two-arm, parallel clinical trial involving 24 participants. The patient group will be treated with acupuncture twice per week for 12 weeks; meanwhile, the healthy control group will not undergo acupuncture treatment. Functional near-infrared spectroscopy assessment and a working memory test will be performed at baseline and every 6 weeks to investigate the therapeutic mechanism of acupuncture. The primary outcome will be measured using the Korean version of the Montreal Cognitive Assessment. The secondary outcomes will be the Alzheimer's Disease Assessment Scale-cognitive subscale score, working memory task accuracy, response rate, response time, and hemodynamic response of the prefrontal lobe. The outcomes will be evaluated at baseline, and at 6 and 12 weeks after subject allocation. DISCUSSION: This clinical pilot trial is designed to determine the feasibility of acupuncture as an effective and safe treatment for improving cognitive function in patients with MCI. Results of this study may provide guidance for future larger-scale clinical trials. TRIAL REGISTRATION: Clinical Research Information Service (CRIS), Republic of Korea: KCT0002451.

RESUMEN
We evaluated neuropharmacological properties of Yuk-Mi-Jihwang-Tang (YJT) against scopolamine injection-induced memory impairment mice model. Mice were orally administered with YJT (50, 100, or 200 mg/kg) or tacrine (TAC, 12.5 mg/kg) for 10 days. At the first day of Morris water maze task, scopolamine (2 mg/kg) was intraperitoneally injected before 30 min of it. The hippocampal memory function was determined by the Morris water maze task for 5 days consecutively. Scopolamine drastically increased escape latency and decreased time spent in target quadrant. Pretreatment YJT properly improved them. Regarding the redox status, YJT significantly reduced the oxidative stress and it also exerted much effort to improve both superoxide dismutase and catalase activities in hippocampal gene expression and protein levels. These effects were well coincided with immunohistochemical analysis of 4-hydroxyneal-positive signals in hippocampal areas. Additionally, acetylcholine esterase activities and brain-derived neurotrophic factor abnormalities in the hippocampal protein levels were significantly normalized by YJT, and their related molecules were also improved. The neuronal proliferation in hippocampal regions was markedly inhibited by scopolamine, whereas YJT notably recovered them. Collectively, YJT exerts much effort to enhance memorial functions through improving redox status homeostasis and partially regulates acetylcholine esterase activities as well as neuronal cell proliferation.
RESUMEN
We aimed to evaluate the protective effects of Yuk-Mi-Jihwang-Tang (YJT) against acute restraint stress-induced brain oxidative damage. A water extract of YJT was prepared and subjected to high performance liquid chromatography - diode array detector-mass spectrometry (HPLC-DAD-MS). Thirty-six heads of C57BL/6J male mice (7 weeks) were divided into six groups (n = 6/group). The mice were orally administrated YJT (0, 50, 100, or 200 mg/kg) or vitamin C (100 mg/kg) for 5 consecutive days before 6 h of acute restraint stress. In the brain tissue, lipidperoxidation, antioxidant components, and pro-inflammatory cytokines were measured, and the serum corticosterone level was determined. Acute restraint stress-induced notably increased lipid peroxidation in brain tissues, and pretreatment with YJT showed a significant decreased the lipid peroxidation levels (p< 0.05). The levels of antioxidant components including total glutathione contents, activities of SOD and catalase were remarkably depleted by acute restraint stress, whereas these alterations were significantly restored by treatment with YJT (p< 0.05 or p< 0.01). The restraint stress markedly increased pro-inflammatory cytokines, such as TNF-α and IL-6 in the gene expression and protein levels (p< 0.05 or p< 0.01). Pretreatment with YJT significantly attenuated serum corticosterone (200 mg/kg, p < 0.05). YJT drastically attenuated the levels of 4- HNE, HO-1, Nox 2 and iNOSwhich were elevated during acute restraint stress, whereas the Nrf2 level was increased in brain tissue protein levels. Our data suggest that YJT protects the brain tissue against oxidative damage and regulates stress hormones.

OBJECTIVES: Ginseng saponin is known to have biological activities in maintaining homeostasis and enhancing vital energy. Enzyme-modified ginseng extract (EMGE) was designed to increase the content of its active constituents and to intensify biological activity. The present study investigated the anti-fatigue effects of EMGE in healthy adults in a randomized, double-blind, placebo-controlled trial. DESIGN: Fifty-two healthy subjects met the diagnostic criteria and were randomly allocated into one of two groups: EMGE (2,000 mg/day) or placebo. EMGE or placebo were administered to each group for 4 weeks. Fatigue scores using the Visual Analogue Fatigue Scale (VAFS) and Revised Piper Fatigue Scale (RPFS) were considered as the primary outcome measure. Life-quality scores were investigated using the Short-Form Health Survey (SF-36). The safety and adverse effects of EMGE were also assessed. RESULTS: A repeated-measures analysis of variance showed that there was a significant difference in the VAFS scores VAFS between the treatment and placebo groups after 4 weeks. The treatment group's score decreased more than that of the placebo group. There was no difference in the RPFS and SF-36 scores between the two groups. There were no fatal adverse effects. CONCLUSION: EMGE treatment for 4 weeks decreased fatigue severity in a healthy population. Adverse effects were rare, and EMGE was generally well tolerated. Randomized, placebo-controlled trials of EMGE are justified in order to elucidate the underlying mechanism of EMGE in combating fatigue.

The medicinal plants Artemisia iwayomogi (A. iwayomogi) and Curcuma longa (C. longa) radix have been used to treat metabolic abnormalities in traditional Korean medicine and traditional Chinese medicine (TKM and TCM). In this study we evaluated the effect of the water extract of a mixture of A. iwayomogi and C. longa (ACE) on high-fat diet-induced metabolic syndrome in a mouse model. Four groups of C57BL/6N male mice (except for the naive group) were fed a high-fat diet freely for 10 weeks. Among these, three groups (except the control group) were administered a high-fat diet supplemented with ACE (100 or 200 mg/kg) or curcumin (50 mg/kg). Body weight, accumulation of adipose tissues in abdomen and size of adipocytes, serum lipid profiles, hepatic steatosis, and oxidative stress markers were analyzed. ACE significantly reduced the body and peritoneal adipose tissue weights, serum lipid profiles (total cholesterol and triglycerides), glucose levels, hepatic lipid accumulation, and oxidative stress markers. ACE normalized lipid synthesis-associated gene expressions (peroxisome proliferator-activated receptor gamma, PPARγ; fatty acid synthase, FAS; sterol regulatory element-binding transcription factor-1c, SREBP-1c; and peroxisome proliferator-activated receptor alpha, PPARα). The results from this study suggest that ACE has the pharmaceutical potential reducing the metabolic abnormalities in an animal model.
RESUMEN
OBJECTIVES: To preliminarily assess the effects of acupuncture on prehypertension and stage I hypertension, and to provide data for further research. DESIGN: A randomized, controlled, assessor-blinded study with an 8-week intervention period and a 4-week follow-up. INTERVENTIONS: Participants were patients with systolic blood pressure (SBP) of 120-159mmHg or diastolic blood pressure (DBP) of 80-99mmHg.Thirty participants were allocated to acupuncture group or untreated control group at a 1:1 ratio. The acupuncture group received standard acupuncture twice weekly for 8 weeks, and was followed-up for 4 weeks after treatment; the control group did not receive any type of anti-hypertensive treatment for 12 weeks. MAIN OUTCOME MEASURES: Primary outcome measure was SBP and DBP at post-treatment. The secondary outcomes were SBP and DBP at follow-up; Euro Quality of life (EQ-5D), heart rate variability (HRV), body mass index (BMI), and blood lipid profile. RESULTS: DBP (-5.7mmHg; P=0.025), but not SBP (-6.0mmHg; P=0.123), was significantly different between groups at post-treatment. Both DBP (-7.8mmHg; P=0.004) and SBP (-8.6mmHg; P=0.031) were significantly different at follow-up. Among the HRV indices, only high frequency power was significantly different between groups at weeks 4 and 8 (P=0.047 and P=0.030, respectively). There were no differences between groups in EQ-5D, BMI or lipid profile. CONCLUSION: The results of this study show that acupuncture might lower blood pressure in prehypertension and stage I hypertension, and further RCT need 97 participants in each group. The effect of acupuncture on prehypertension and mild hypertension should be confirmed in larger studies. TRIAL REGISTRATION: KCT0000496.

ETHNOPHARMACOLGICAL RELEVANCE: Artemisiaiwayomogi Kitamura and Curcuma longa Linne. (ACE) has been popularly used to treat atherosclerosis as well as hyperlipidemia in the Asian countries. OBJECTIVE: Antiatherosclerotic and anti-hyperlipidemic effects of ACE were evaluated at protein and gene expression level by using apoE(-/-) mice. METHOD: Apoprotein E deficient (apoE(-/-)) mice were randomly divided into five groups and fed freely Western diet (WD) which contained ACE (50, 100 and 200mg/kg) or curcumin (50mg/kg). The C57/BLJ mice were used as normal and which were fed the WD. After 10 weeks of being fed the WD, the atherosclerosis related mediators and hyperlipidemia induced hepatic steatosis were analyzed in serum, aorta tissue or hepatic tissues. RESULTS: Ten-week feeding of WD considerably increased the serum lipid profiles including total cholesterol (TC), low density lipoprotein, high density lipoprotein (HDL), triglyceride, TC/HDL ratio and glucose, and also elevated the total reactive oxygen species (ROS) and inflammatory cytokines (tumor necrosis factor-α, TNF-α; and interlukin-6, IL-6) in the serum levels. ACE treatment significantly resolved these alterations. The aortic lesion formation was significantly decreased as were lipid formations by ACE treatment. Moreover, ACE not only caused significant decreases of the lipid drops on the hepatic tissues, but also restored the antioxidant components. The gene expression levels including SREBP-1c, FAS, SCD-1, PPAR-α, CPT-1, IL-6, IL-1ß and TNF-α in hepatic tissue were altered by Western diet fed in apoE(-/-) mice, while ACE treatment significantly normalized those alterations. CONCLUSIONS: The ACE treatment is beneficial for atherosclerosis in arterial area and hyperlipidemia induced hepatic tissue steatosis.
