RESUMO

BACKGROUND: Behçet's disease (BD) is a chronic inflammatory systemic disease that affects multiple organs. The causes of BD are still unknown, but it is primarily characterized by autoimmune reaction in the blood vessels. Current research focuses on treatments that can reduce the non-typical inflammatory responses of BD. Nevertheless, studies on improving the inflammatory effect of BD using inflammation mechanisms are still insufficient. Therefore, we conducted the integrated treatments related to inflammation modulation and achieved alleviation of symptoms in BD mice. METHODS: To understand the complex etiology of BD and compare its management, the herpes simplex virus (HSV)-induced BD mouse model was used. In order to alleviate the inflammatory response in BD mice, Taraxaci Herba (TH, herbal medicine), R7050-a TNFα inhibitor, and a mixture of TH and R7050 were injected for 2 weeks repetitively. The SCORAD index was examined to evaluate the cutaneous inflammations. In addition, histological changes and inflammatory factors were analyzed. RESULTS: Repetitive injection of TH and/or R7050 reduced the symptoms of BD and significantly decreased IL-6, IL-1ß, and TNFα in blood sera. Moreover, this treatment reduced the ulcers and the deterioration of skin. CONCLUSIONS: The results of our study showed that the down-regulation of inflammatory factors is related to the control of immune responses in BD models, suggesting that a mixed drug treatment may be more effective in improving the condition of BD.

RESUMO

ABSTRACT: Gait rehabilitations have been abundantly performed for post-stroke patients, because gait is the most important factor for the return of post-stroke patients to daily life. However, conventional uniform gait rehabilitations tend to be tedious and reduce motivation. The aim of this study was to contribute to the development of personalized rehabilitation of gait by identifying differences in gait recovery pattern according to the paralyzed side of post-stroke patients.The gait analysis was performed on stroke patients who are right-handed and can walk independently. We retrospectively analyzed the results of pelvic movements and displacement of center of pressure (COP) during gait using corresponding equipments. To show the difference of gait recovery pattern according to the paralyzed side, we divided subjects into two groups, right (n = 19) and left (n = 20) hemiparesis group. The measured variables were as follows: tilt, obliquity, and rotation symmetries of pelvis; area, velocity, and lateral symmetry of COP.First, in the left hemiparesis group, obliquity (P < .01) and rotation (P < .01) symmetries of the movement of the pelvis were significantly improved in the follow-up compared to the initial gait analysis. In the right hemiparesis group, tilt (P < .001), obliquity (P < .001), and rotation (P < .05) symmetries were significantly improved in the follow-up compared to the initial gait analysis. Second, COP area and COP velocity values in the follow-up were significantly smaller than those in the initial gait analysis in the left (P < .001, P < .05) and right (P < .001, P < .01) hemiparesis groups. The positive value of lateral symmetry increased, although not a significant difference statistically, as walking ability improved in both groups. In the correlation analysis among variables obtained using Treadmill, there were significant positive linear relationships between the lateral symmetry and the COP area (P < .05), and between the COP velocity and the lateral symmetry (P < .001) of the follow-up gait analysis in the right hemiparesis group.It was confirmed that the gait recovery pattern differs according to the paralyzed side of post-stroke patients and the role of the intact side, such as moving the COP to the intact side, is important for the improvement of gait function in both groups.This study was registered with the Clinical Research Information Service (CRIS) of the Korea National Institute of Health (NIH), Republic of Korea (KCT0002984) and was approved by the Institutional Review Board (IRB) of the WKUGH (WKIRB [2018-25], November 28, 2018).

RESUMO

BACKGROUND: Migraine is a common reason for primary headache disorders. Cupping is a frequently used traditional intervention for controlling pain including migraine. There have been no systematic reviews on the clinical effects of cupping on migraine. OBJECTIVE: This systematic review and meta-analysis aimed to evaluate the effectiveness of cupping therapy for migraine. The search strategy was built for the presence of related keywords, such as "migraine" and "cupping therapy", in the title and abstract of research articles indexed in the MEDLINE, EMBASE, CENTRAL, and other databases. The randomized controlled trials (RCTs) of cupping therapy for migraine were searched and selected from inception to May 2019. We searched eight databases including PubMed, EMBASE, Cochrane Central Register of Controlled Trials. The selection process and the quality assessment were performed by 2 authors independently. The meta-analysis was conducted and qualitative analysis was also performed. RESULTS: 218 studies were identified, and 6 RCTs were enrolled in this review. In comparison to drugs, wet cupping showed a higher total effective rate (TER). In the dry cupping plus acupuncture, the result of TER showed more effectiveness (RR 1.05, 95% CI 0.99 to 1.12, P=0.13) compared with acupuncture alone, but there was no statistically significant difference. In qualitative analysis, the results showed wet cupping plus drugs treatment could quickly relieve pain and significantly improve patients' quality of life and wet cupping could reduce headache pain. CONCLUSION: Cupping therapy could be effective for the treatment of migraine. However, the qualities of the evidence were low, so well-designed RCTs are needed to confirm the effectiveness of cupping. Systematic review registration: PROSPERO registration number is CRD42017054979.

RESUMO

BACKGROUND: Although the incidence of AD, including gastrointestinal AD, increases every year, there is no effective therapy for it yet. This causes high medical costs to be spent on the management of autoimmune patients every year. The aim of this study is to identify the characteristics related to the causes and symptoms of gastrointestinal autoimmune disease (AD) by collecting patients' information and to further contribute to the development of an integrative medicine therapy for gastrointestinal AD. METHODS/DESIGN: This study is a registry study of patients diagnosed with gastrointestinal AD. Subjects who voluntarily sign a written consent form after receiving a sufficient explanation will be assessed for compliance with the inclusion and exclusion criteria through a screening process on their first visit. A total of 35 subjects will be recruited; 15 will be assigned to the patient group, 10 to the control group, 8 to the caregiver group, and 2 to the medical staff group. The clinical information of the subjects will be evaluated through statistical analyses. As this study is a registry study, it will not test specific hypotheses. DISCUSSION: If this study identifies the significant characteristics of gastrointestinal AD patients, the results will be useful for the development of integrative medicine methods for the treatment of gastrointestinal AD. STUDY REGISTRATION: This study was registered with the Clinical Research Information Service (CRIS) of the Korea National Institute of Health (NIH), Republic of Korea (KCT0003976, date of registration: May 23, 2019).

RESUMO

In Donguibogam, a representative encyclopedic source of knowledge on traditional Korean medicine, left-sided hemiparesis due to stroke is called "Tan" as a sort of "Heyol-Byeong," while right-sided hemiparesis due to stroke is called "Tan" as a sort of "Gi-Byeong." According to the theory of Donguibogam, diseases on the left or right side of the human body must be treated differently. Clinically, the symptoms caused by left and right hemisphere lesions in stroke patients differ, as the functions of the left and right hemispheres differ. Considering these facts, when treating patients in clinical practice, it may be useful to distinguish between diseases on the left or right side according to Donguibogam. This study set out to confirm whether side-dependent gait rehabilitation could be used to treat hemiparetic stroke patients. Gait was selected for analysis, as it is the most important factor in returning stroke patients to daily life.This study conducted a retrospective chart review of stroke patients who satisfied the following criteria: outpatient or inpatient at the Wonkwang University Korean Medicine Hospital in Gwangju (WKUGH) with hemiparesis due to stroke; aged between 19 and 85 years old; with a stroke onset within the past 6 months; having undergone gait analysis (GAITRite) more than twice between September 1, 2017 and June 30, 2018 at the WKUGH, with a minimum 2-week interval between the first and next gait analysis; right-handed stroke patient; able to walk unaided. The spatio-temporal parameters for analysis included the FAP, walking velocity, step length, stance time, and swing time as obtained with GAITRite.In the initial gait analysis, there was no significant difference between the 2 groups in all spatio-temporal parameters. However, in the follow-up gait analysis, the left hemiparesis group showed a significantly higher FAP and faster walking velocity than the right hemiparesis group.This study found a difference in the recovery rate between the left and right hemiparesis groups. Based on this, we suggest that a different treatment strategy for gait rehabilitation can be used according to the paralyzed side.This study was approved by the Institutional Review Board (IRB) of the Wonkwang University Korean Medicine Hospital in Gwangju (WKUGH), Republic of Korea (WKIRB 2018 - 25, November 28, 2018). This trial was registered with the Clinical Research Information Service (CRIS) of the Korea National Institute of Health (NIH), Republic of Korea (KCT0002984).

RESUMO

RATIONALE: Injinoryung-San-Gagambang (IJORS) effectively improves hepatic dysfunction caused by polypharmacy in stroke patients. PATIENT CONCERNS: We present 3 cases of hepatic dysfunction caused by polypharmacy, one of which was a 51-year-old man with cerebellum infarction and pneumonia as a complication of stroke. He took multiple medications because of baseline diseases. After recurrence of pneumonia, his laboratory tests showed abnormal aminotransferase levels. Another patient was an 81-year-old woman with cerebral infarction at the right-middle cerebral artery. She was also taking >5 medications. Her laboratory tests conducted on admission showed abnormally elevated aminotransferase levels. The last patient was 77-year-old man with cerebral infarction at the left-middle cerebral artery. He also had an abdominal aneurysm, a thoracic aortic aneurysm, and a myocardial infarction. After taking multiple medications including healthy functional foods, his laboratory tests showed abnormally elevated aminotransferase levels. DIAGNOSIS: Diagnosis is conducted with the result of laboratory test including blood count, chemistry test. INTERVENTIONS: All 3 patients received the same herbal treatment (IJORS decoction) for 1 to 3 weeks. OUTCOMES: All 3 patients' abnormal serum aminotransferase level were significantly improved by IJORS decoction treatment while keeping other medicines. LESSONS: IJORS can be considered as an effective treatment for hepatic dysfunction induced by numerous medications in stroke patients.

RESUMO

INTRODUCTION: In Traditional Korean Medicine (TKM), diseases on the left or right side of the human body have been treated differently according to the theory of Donguibogam, which is an encyclopedic source for TKM. In the Wind chapter of Donguibogam, left hemiparesis due to stroke is called Tan, a sort of Hyeol-Byeong, and right hemiparesis due to stroke is called Tan, a sort of Gi-Byeong. As neuroscience develops, it has been shown that the functions of the left and right hemispheres differ, as do the symptoms caused by differently located lesions in the brain. In light of these recent findings and the theory of Donguibogam, it may be useful when treating patients in clinical practice to consider the side of the human body on which symptoms appear. The aim here is to establish whether side-dependent treatments are more effective in treating patients with symptoms on different sides of the body. Specifically, this exploratory study investigates changes in gait pattern among stroke patients with hemiparesis or hemiplegia during gait recovery. METHODS: To develop this protocol, a retrospective review of charts will be used to assess differences in gait recovery patterns among stroke patients with left or right hemiparesis, using gait analysis systems that include GAITRite, G-walk, and Treadmill. The data will be selected from gait analysis performed more than twice in the period from September 1, 2017 to June 31, 2018 at Wonkwang University Gwangju Hospital (WKUGH). RESULTS: The primary outcomes include spatiotemporal parameters obtained using GAITRite (FAP, velocity, step length, swing time, and stance time); symmetric parameters obtained using G-walk (tilt, obliquity, and pelvis rotation symmetry); and center of pressure (COP) area and velocity as measured by Treadmill. DISCUSSION: This will be the first study to analyze the gait recovery pattern of stroke patients according to the paralyzed side by comparing spatiotemporal, symmetric, and COP parameters using gait analysis systems. Like all retrospective studies, the present research was subject to certain limitations related to bias (selection bias, recall bias, misclassification bias, confounding value bias), difficulty in assessing temporal relationships, and small sample size. However, these limitations were of less significance here because gait parameters and body side of symptoms of hemiplegia or hemiparesis are relatively clear. CONCLUSION: If the use of gait analysis systems (GAITRite, G-walk, and Treadmill) confirms differences in gait recovery pattern among stroke patients according to the paralyzed side, the findings will provide essential evidence for differential treatment of stroke patients on that basis.

RESUMO

INTRODUCTION: Assessments of the range of motion (ROM) in human joints have been widely used to evaluate the joint condition. Although maker based motion capture system is the most popular and practical method in the clinical field, there have been limitations such as the relatively long time required in procedure or influence of attached markers on natural movement. Recently, markerless motion capture systems have been actively developed due to their relatively lower cost and convenience for installation. The POM-Checker (Team Elysium Inc., Seoul, Rep of Korea), a markerless motion capture system, was developed with new algorithms to assess the ROM in human joints. However, the measure of the POM-Checker has not been compared with a golden-standard device in evaluating the ROM in the human joints. So we developed a protocol to evaluate the validation and reliability of the POM-Checker in measuring the shoulder ROM. This study will also provide a standard procedure to measure the shoulder ROM with the POM-Checker and 3D motion analysis system simultaneously. METHODS/DESIGN: This protocol is for a single institution comparative study to evaluate the validity and reliability of POM-Checker. Six participants will be recruited. We will measure the angles of shoulder abduction and flexion with POM-Checker and 3D motion analysis system simultaneously. The primary outcome is the angles of shoulder abduction and flexion. DISCUSSION: This will be the first study to analyze the validity and reliability of POM-Checker in measuring shoulder ROM. Although the sample size of this study is small, it may not influence on the results conclusively, because the measures are very precise numerical angles. Furthermore, the angles of shoulder movements will be measured with both devices simultaneously. CONCLUSION: The results of the study will be helpful to find out the validity and reliability of a new developed ROM measure device, POM-Checker, by comparison with a golden standard system, 3D motion capture system, in measuring the shoulder ROM. It will also contribute to use of the POM-Checker in measuring the ROMs in many human joints.

RESUMO

BACKGROUND AND OBJECTIVE: A migraine is one of the primary headache disorders. Acupuncture has been widely used to treat migraine. Furthermore, electroacupuncture (EA) treatment has been also used to treat migraine. However, there has been no systematic review by assessing efficacy and safety of EA on migraine. This protocol is developed to conduct a systematic review and meta-analysis to evaluate the evidences related to the effectiveness and safety of EA on migraine. METHODS AND ANALYSIS: This protocol follows the guideline according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis Protocol and registered on the International Prospective Register of Systematic Reviews (PROSPERO). The following seven databases will be searched from their inception to September 2016: Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, OASIS, the Korean Traditional Knowledge Portal, the Korean Medical Database and the China National Knowledge Infrastructure (CNKI). This Systemic review will include only the randomized controlled clinical trials (RCTs) of acupuncture therapy on migraine. We will perform data extraction, study selection, assessment with risk of bias and data analysis. The primary outcomes of this study are headache pain intensity and the total treatment effective rate. And this protocol study for systematic reviews, the approval of IRB was not required. ETHICS AND DISSEMINATION: This systematic review will not need ethical approval, because it doesn't involve human beings. We will publish this systematic review electronically in a peer-reviewed journal. This systematic review will give healthcare practitioners good practical guide and information for treating migraine. SYSTEMATIC REVIEW REGISTRATION: PROSPEROCRD42018085099.

RESUMO

It is important to reduce poststroke depression (PSD) to improve the stroke outcomes and quality of life in stroke patients, but the underlying mechanisms of PSD are not completely understood. As many studies implicate dysregulation of hypothalamic-pituitary-adrenal axis in the etiology of major depression and stroke, we compared the cortisol awakening response (CAR) of 28 admitted PSD patients with that of 23 age-matched caregiver controls. Saliva samples for cortisol measurement were collected immediately, 15, 30, and 45 min after awakening for two consecutive days. Depressive mood status in PSD patients was determined with Beck Depression Inventory and Hamilton Depression Rating Scale. Salivary cortisol levels of PSD patients did not rise significantly at any sampling time, showing a somewhat flat curve. Caregiver controls showed significantly higher CAR at 15 and 30 min after awakening compared to PSD patients even though the two groups did not differ at awakening or 45 min after awakening. Area-under-the-curve analysis revealed a significant negative correlation between the CAR and the degree of depression in PSD patients. Thus, our findings suggest that poststroke depression is closely related with dysfunctional HPA axis indicated by blunted CAR.

RESUMO

[Purpose] The present study examined whether electro-acupuncture therapy reduces post-stroke depression (PSD) and whether motor function impairments interact with the effects of the therapy. [Subjects] Twenty-eight PSD patients were assessed and assigned to either a good or poor motor function group depending on their motor grade. [Methods] The Beck Depression Inventory (BDI), Hamilton Depression Rating Scale (HDRS) and Manual Muscle Test (MMT) were administered at the screening and initial phases of the study, and at the 4th, 8th, 12th and 16th week of the daily electro-acupuncture treatment. [Results] The electro-acupuncture treatment reduced PSD (as assessed by BDI and HDRS) of the patients. In particular, the depression of the good motor function group was significantly more reduced than that of the poor motor function group. The degree of motor function impairment did not change throughout the study in either group. [Conclusion] The results of the present study demonstrate that electro-acupuncture therapy can improve PSD, and that the treatment effect varies depending on the degree of motor function impairment.

RESUMO

Considerable evidence indicates that amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease of the motor system, has an enormous impact on the patient's emotional and physical well-being. As previous findings indicated that particularly the rise in cortisol levels immediately after awakening, i.e., the cortisol awakening response (CAR), is associated with indices of physical and emotional well-being, we compared the CAR of 29 admitted ALS patients with that of 12 age-matched caregiver controls. Saliva samples for cortisol measurement were collected immediately, 15, 30 and 45 min after awakening. The severity of ALS progression was quantified using the ALS functional rating scale (ALSFRS) and manual muscle test (MMT). Depressive mood status in ALS patients was determined with the Beck Depression Inventory (BDI) and Hamilton Depression Rating Scale (HDRS). Salivary cortisol levels of ALS patients did not differ from those of caregiver controls at awakening, 15 min or 45 min after awakening, but were significantly lower at 30 min after awakening. Area under the curve analysis confirmed that the CAR was significantly smaller in ALS patients than in caregiver controls. A smaller CAR in ALS patients was significantly correlated to poorer clinical status, as assessed with both the ALSFRS and MMT rating instruments. Further, a smaller CAR significantly correlated with a more severe depressive mood status. No correlations were observed between total cortisol output during the first 45 min post-awakening and clinical or depressive status. In conclusion, our findings indicate that ALS patients show a blunted CAR, correlated with disease and depression severity.

RESUMO

We used the [F-18]FDG micro PET neuroimaging technique to investigate changes in brain activity induced by acute stress in rats. Animals were given immobilization stress for 1 or 2 h, or 1-h stress followed by 1-h recovery, after which their brains were scanned. Plasma corticosterone levels measured at various time points in separate groups of rats showed a rapid increase during stress and slower decrease after termination of the stress. Immobilization stress given for an hour activated the hypothalamus, entorhinal and insular/piriform cortices, and raphe pallidus nucleus. At the same time, the dorsal hippocampus, thalamus, other cortical areas (motor, somatosensory and barrel field), striatum, superior colliculus and cerebellum were deactivated. With 2-h immobilization stress, the activity of the hypothalamus, various cortical areas and dorsal hippocampus habituated during the second hour while that of the thalamus and cerebellum did not. During 1-h recovery, the hypothalamic activation and widespread cortical deactivation disappeared, but the dorsal hippocampus, thalamus and cerebellum still remained significantly deactivated. Additional brain areas such as the septum and prelimbic cortex now showed deactivation during recovery. Changes in glucose metabolism in the dorsal hippocampus and hypothalamus exhibited a highly significant negative correlation, supporting the view that the hippocampus is involved in regulating the stress response of the hypothalamo-pituitary-adrenal axis. The advantages and limitations of the [F-18]FDG micro PET used in this study are discussed.

RESUMO

Seogak Jihwang-Tang (SJT) has been widely used to treat patients suffering from cerebral infarction. However, very little scientific investigation has been carried out. We investigated the effect of SJT on the production of various cytokines using peripheral blood mononuclear cells from the cerebral infarction patients presenting with altered consciousness. The cytokines production was determined by enzyme-linked immunosorbent assay. The amount of IL-4, IL-10 and TGF-beta1 in culture supernatant significantly increased in the SJT, lipopolysaccharide (LPS) or PHA-treated cells compared to unstimulated cells (P < 0.05). We also showed that increased IL-4 and IL-10 levels by LPS or phytohaemagglutinin (PHA) were significantly inhibited by SJT in a dose-dependent manner. Maximal inhibition rate of IL-4 and IL-10 production by SJT was 45.6 +/- 3.3% and 61 +/- 4.7% for LPS-stimulated cells and 27.3 +/- 1.2% and 83.6 +/- 2% for PHA-stimulated cells, respectively (P < 0.05). On the other hand, SJT significantly increased the LPS or PHA-induced TGF-beta1 production (P < 0.05). These data suggest that SJT has a regulatory effect on the cytokines production, which might explain its beneficial effect in the treatment of cerebral infarction.

RESUMO

The herbal formulation "Jeo Dang-Tang" (JDT) has long been used for various cerebrovascular diseases. However, very little has scientific investigation been carried out. The aim of the present study is to investigate the effect of JDT on the production of various cytokines in the patients with cerebral infarction (CI). Peripheral blood mononuclear cells (PBMC) obtained from the patients with CI were cultured for 24h in the presence or absence of lipopolysaccharide (LPS) or phytohemagglutinin (PHA). The amount of interleukin (IL)-4, IL-10 and transforming growth factor (TGF)-1beta, in culture supernatant, was significantly increased in the JDT, LPS or PHA treated cells compared to unstimulated cells (P < 0.05). We also show that increased IL-4, and IL-10 level by LPS or PHA was significantly inhibited by JDT in a dose-dependent manner. Maximal inhibition rate of IL-4 and IL-10 production by JDT was 45 +/- 2% and 51 +/- 5% for LPS-stimulated cell and 41.5 +/- 3% and 70.8 +/- 2% for PHA-stimulated cells, respectively (P < 0.05). On the other hand, JDT significantly increased the LPS or PHA-induced TGF-beta1 production (P < 0.05). These data suggest that JDT has a regulatory effect on the cytokines production, which might explain its beneficial effect in the treatment of CI.
