Effectiveness of Acupotomy Combined with Epidural Steroid Injection for Lumbosacral Radiculopathy: A Randomized Controlled Pragmatic Pilot Study. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:175. [PMID: 38276054 PMCID: PMC10818306 DOI: 10.3390/medicina60010175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 01/04/2024] [Accepted: 01/17/2024] [Indexed: 01/27/2024]
Abstract
Background and Objectives: This pilot study aimed to evaluate the clinical effectiveness, cost-effectiveness, and safety of acupotomy combined with epidural steroid injection (ESI) in lumbosacral radiculopathy and examine its feasibility for the main study. Materials and Methods: This randomized, controlled, two-arm, parallel, assessor-blinded, pragmatic study included 50 patients with severe lumbosacral radiculopathy who had insufficient improvement after an ESI. Patients were randomized (1:1 ratio) into a combined treatment (acupotomy + ESI, experimental) and an ESI single treatment (control) group. Both groups underwent a total of two ESIs once every 2 weeks; the experimental group received eight additional acupotomy treatments twice a week for 4 weeks. Types of ESI included interlaminar, transforaminal, and caudal approaches. Drugs used in ESI comprised a 5-10 mL mixture of dexamethasone sodium phosphate (2.5 mg), mepivacaine (0.3%), and hyaluronidase (1500 IU). The primary outcome was the difference in changes from baseline in the Oswestry Disability Index (ODI) scores between the groups at weeks 4 and 8. The incremental cost-utility ratio (ICUR) was calculated to evaluate the cost-effectiveness between the groups. Adverse events (AEs) were assessed at all visits. Results: Mean ODI scores for the experimental and control groups were -9.44 (95% confidence interval [CI]: -12.71, -6.17) and -2.16 (95% CI: -5.01, 0.69) at week 4, and -9.04 (95% CI: -12.09, -5.99) and -4.76 (95% CI: -7.68, -1.84) at week 8, respectively. The difference in ODI score changes was significant between the groups at week 4 (p = 0.0021). The ICUR of the experimental group versus the control group was as economical as 18,267,754 won/quality-adjusted life years. No serious AEs were observed. Conclusions: These results demonstrate the potential clinical effectiveness and cost-effectiveness of acupotomy combined with ESI for lumbosacral radiculopathy and its feasibility for a full-scale study. Larger, long-term follow-up clinical trials are needed to confirm these findings.

Comparison of Concordance between Chuna Manual Therapy Diagnostic Methods (Palpation, X-ray, Artificial Intelligence Program) in Lumbar Spine: An Exploratory, Cross-Sectional Clinical Study. Diagnostics (Basel) 2022; 12:2732. [PMID: 36359575 PMCID: PMC9689192 DOI: 10.3390/diagnostics12112732] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 11/04/2022] [Accepted: 11/07/2022] [Indexed: 10/15/2023] Open
Abstract
Before Chuna manual therapy (CMT), a manual therapy applied in Korean medicine, CMT spinal diagnosis using palpation or X-ray is performed. However, studies on the inter-rater concordance of CMT diagnostic methods, concordance among diagnostic methods, and standard CMT diagnostic methods are scarce. Moreover, no clinical studies have used artificial intelligence (AI) programs for X-ray image-based CMT diagnosis. Therefore, this study sought a feasible and standard CMT spinal diagnostic method and explored the clinical applicability of the CMT-AI program. One hundred participants were recruited, and the concordance within and among different diagnostic modalities was analyzed by dividing them into manual diagnosis (MD), X-ray image-based diagnosis (XRD) by experts and non-experts, and XRD using a CMT-AI program by non-experts. Regarding intra-group concordance, XRD by experts showed the highest concordance (used as a gold standard when comparing inter-group concordance), followed by XRD using the AI program, XRD by non-experts, and then MD. Comparing diagnostic results between the groups, concordance with the gold standard was the highest for XRD using the AI program, followed by XRD by non-experts, and MD. Therefore, XRD is a more reasonable CMT diagnostic method than MD. Furthermore, the clinical applicability of the CMT-AI program is high.

A comparative study of a nerve block therapy with and without a deeply inserted acupotomy applied to hyeopcheok points for lumbosacral radiculopathy: Safety, effectiveness, cost-effectiveness (a randomized controlled, two-arm, parallel study, pilot study, assessor-blind). Medicine (Baltimore) 2022; 101:e28983. [PMID: 35244070 PMCID: PMC8896499 DOI: 10.1097/md.0000000000028983] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Accepted: 02/14/2022] [Indexed: 01/04/2023] Open
Abstract
INTRODUCTION The prevalence of lumbosacral radiculopathy is estimated to be approximately 3% to 5% in patient populations. Lumbosacral radiculopathy is largely caused by a complex interaction between biomechanical and biochemical factors. Nerve block therapy (NBT) mainly treats lumbosacral radiculopathy by improving the biochemical factors, whereas acupotomy mainly focuses on improving the biomechanical factors. Therefore, it is thought that synergistic effects may be obtained for the treatment of lumbosacral radiculopathy when both NBT and acupotomy are combined. However, no study in China and Korea, where acupotomy is majorly provided, has reported the effects of such a combination treatment. Therefore, this study aimed to evaluate the safety, effectiveness, and cost-effectiveness of the concurrent use of a deeply inserted acupotomy and NBT for the treatment of lumbosacral radiculopathy. METHODS/DESIGN This is an open-label, parallel, assessor-blinded, randomized controlled trial, which will include 50 patients with lumbosacral radiculopathy. After patients voluntarily agree to participate in the study, they will be screened, and will undergo necessary examinations and tests according to the protocol. Those who satisfy the selection criteria will be randomly assigned to either the NBT + acupotomy or NBT groups in a 1:1 ratio. Both groups will undergo 2 NBTs once every 2 weeks from 1 week after the screening test. The treatment group will receive additional acupotomy twice a week for 4 weeks. The primary endpoint is the Oswestry Disability Index, whereas the secondary endpoints are the Numeral Rating Scale, European Quality of Life 5-dimension, McGill pain Questionnaire, Roland-Morris Disability Questionnaire, safety assessment, and economic feasibility evaluation. The measurements will be made at 0, 2, 4, and 8 weeks. ETHICS AND DISSEMINATION This trial has received complete ethical approval from the Ethics Committee of Catholic Kwandong University International St. Mary's Hospital (IS20OISE0085). We intend to submit the results of the trial to a peer-reviewed journal and/or conferences.

Comparison of concordance between chuna manual therapy diagnosis methods (palpation, X-ray, artificial intelligence program) in lumbar spine: An exploratory, cross-sectional, prospective observational study protocol. Medicine (Baltimore) 2021; 100:e28177. [PMID: 34941072 PMCID: PMC8701932 DOI: 10.1097/md.0000000000028177] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Accepted: 11/19/2021] [Indexed: 01/05/2023] Open
Abstract
INTRODUCTION Chuna manual therapy (CMT) is a type of manual medicine practiced by Korean medical doctors in South Korea. Spinal diagnosis in CMT uses a system that applies manual diagnostic and X-ray tests to detect specific vertebral malpositions, based on the relative alignment across vertebral bodies. Recently, artificial intelligence (AI) programs have been developed to assist in the radiological diagnosis of CMT using X-ray images. Nevertheless, a few clinical studies have reported on the concordance between diagnosticians, diagnostics methodologies, and the use of AI programs for diagnosing CMT. At present, the evidence to support CMT diagnosis is insufficient. This study thus aims to overcome such limitations by collecting and comparing CMT diagnostic data from experts and non-experts through manual diagnosis, X-ray test, and images obtained using an AI program. The study aims to search for CMT diagnosis methods with more outstanding rationality and consistency and to explore the potential use of AI-based CMT diagnosis programs. METHODS/DESIGN This study will be conducted as an exploratory, cross-sectional, prospective observational study that will recruit 100 non-specialist subjects. Each subject will submit a signed consent after the screening test and undergo L-spine standing AP & lateral X-ray imaging. Manual CMT diagnosis will be performed by 3 CMT experts according to the standard operation procedure (SOP). The X-ray images of the 100 subjects will subsequently be used to make the CMT radiological diagnoses according to the same SOP by the CMT expert group (n = 3) and CMT non-expert group (n = 3). Among the subjects, those in the non-expert group will receive another CMT radiological diagnosis with spinal data obtained using the AI program, approximately 1 month from after initial diagnosis.Based on the collected diagnostic data, within- and between-group concordance levels will be assessed for each diagnostic method. The verified level of concordance will be used to test the potential use of CMT diagnostic method and CMT AI programs with high levels of rationality and consistency. ETHICS AND DISSEMINATION This trial has received complete ethical approval from the Wonkwang University Korean Medicine Hospital (IRB 2021-8). We intend to submit the results of the trial to a peer-reviewed journal and/or conferences.

Preliminary outcomes of arthroscopic biceps rerouting for the treatment of large to massive rotator cuff tears. J Shoulder Elbow Surg 2021; 30:1384-1392. [PMID: 32919044 DOI: 10.1016/j.jse.2020.08.023] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 08/07/2020] [Accepted: 08/17/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND We aimed to evaluate the short-term outcomes of arthroscopic biceps rerouting (ABR) for the treatment of large to massive rotator cuff tears (LMRCTs). METHODS A prospective evaluation of patients treated with ABR for the repair of LMRCTs was performed, with a minimum follow-up period of 18 months. Range of motion and functional outcomes (visual analog scale pain score, American Shoulder and Elbow Surgeons score, and Korean Shoulder Scale score) were assessed preoperatively and at final follow-up. Radiographs were used to evaluate the acromiohumeral interval (AHI). Magnetic resonance imaging was performed at 2 and 12 months postoperatively to examine the integrity of the repaired rotator cuff tendons. RESULTS Eighty patients who met the study criteria underwent ABR from March 2017 to January 2019 in our hospital. Of these patients, 61 could be evaluated ≥18 months after surgery. The average age of the enrolled patients was 64.5 years. The visual analog scale pain score decreased from 3.7 preoperatively to 1.6 at final follow-up (P = .019), the American Shoulder and Elbow Surgeons score improved from 60.0 to 85.2 (P < .001), and the Korean Shoulder Scale score improved from 64.3 to 85.3 (P = .001). Assessment of range of motion showed significant improvement in forward flexion (from 138° to 146°, P < .001), external rotation at 90° of abduction (from 80° to 85°, P = .037), and internal rotation (from spinal level 9 to spinal level 10, P = .015) from preoperatively to last follow-up. The AHI was 7.1 mm at baseline and improved significantly to 9.7 mm at 3 months postoperatively (P < .001). The mean AHI at last follow-up was only 9 mm, but this was still significantly better than the mean preoperative AHI (P < .001). Of the patients, 16 (26%) exhibited a retear of the repaired rotator cuff on magnetic resonance imaging at 12 months postoperatively. Male sex was the only significant risk factor for retear (P = .037). CONCLUSION ABR improved the functional and radiologic outcomes of patients with LMRCTs. The ABR technique can be a useful treatment option for LMRCTs.

Efficacy and safety of acupuncture treatment as an adjunctive therapy after knee replacement: Single-center, pragmatic, randomized, assessor blinded, pilot study. Medicine (Baltimore) 2021; 100:e24941. [PMID: 33725856 PMCID: PMC7969218 DOI: 10.1097/md.0000000000024941] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 02/08/2021] [Indexed: 01/05/2023] Open
Abstract
INTRODUCTION Total knee replacement (TKR) is a surgical procedure that is being increasingly performed as a result of population aging and the increased average human life expectancy in South Korea. Consistent with the growing number of TKR procedures, the number of patients seeking acupuncture for relief from adverse effects, effective pain management, and the enhancement of rehabilitative therapy effects and bodily function after TKR has also been increasing. Thus, an objective examination of the evidence regarding the safety and efficacy of acupuncture treatments is essential. The aim of this study is to verify the hypothesis that the concurrent use of acupuncture treatment and usual care after TKR is more effective, safe, and cost-effective for the relief of TKR symptoms than usual care therapy alone. METHODS/DESIGN This is an open-label, parallel, assessor-blinded randomized controlled trial that includes 50 patients with TKR. After screening the patients and receiving informed consent, the patients are divided into two groups (usual care + acupuncture group and usual care group); the patients will then undergo TKR surgery and will be hospitalized for 2 weeks. The patients will receive a total of 8 acupuncture treatments over 2 weeks after surgery and will be followed up at 3, 4, and 12 weeks after the end of the intervention. The primary outcome is assessed using the Korean version of the Western Ontario and McMaster Universities Arthritis Index (K-WOMAC), and the secondary outcome is measured using the Numerical Rating Scale (NRS), Risk of Fall, and Range of Motion (ROM). Moreover, the cost per quality-adjusted life years (QALYs) is adopted as a primary economic outcome for economic evaluation, and the cost per NRS is adopted as a secondary economic outcome. ETHICS AND DISSEMINATION This trial has received complete ethical approval from the Ethics Committee of Catholic Kwandong University International St. Mary's Hospital (IS17ENSS0063). We intend to submit the results to a peer-reviewed journal and/or conferences. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03633097.

Abstract
Objective We aimed to develop and validate a deep learning system for fully automated segmentation of abdominal muscle and fat areas on computed tomography (CT) images. Materials and Methods A fully convolutional network-based segmentation system was developed using a training dataset of 883 CT scans from 467 subjects. Axial CT images obtained at the inferior endplate level of the 3rd lumbar vertebra were used for the analysis. Manually drawn segmentation maps of the skeletal muscle, visceral fat, and subcutaneous fat were created to serve as ground truth data. The performance of the fully convolutional network-based segmentation system was evaluated using the Dice similarity coefficient and cross-sectional area error, for both a separate internal validation dataset (426 CT scans from 308 subjects) and an external validation dataset (171 CT scans from 171 subjects from two outside hospitals). Results The mean Dice similarity coefficients for muscle, subcutaneous fat, and visceral fat were high for both the internal (0.96, 0.97, and 0.97, respectively) and external (0.97, 0.97, and 0.97, respectively) validation datasets, while the mean cross-sectional area errors for muscle, subcutaneous fat, and visceral fat were low for both internal (2.1%, 3.8%, and 1.8%, respectively) and external (2.7%, 4.6%, and 2.3%, respectively) validation datasets. Conclusion The fully convolutional network-based segmentation system exhibited high performance and accuracy in the automatic segmentation of abdominal muscle and fat on CT images.

Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) occurs in 68.1% of patients within the first month of undergoing chemotherapy; however, standardized treatment for CIPN has not been established yet. The efficacy of acupuncture, a widely used treatment for CIPN in South Korea, has not been studied sufficiently. This study aimed to review the studies that evaluated the efficacy of acupuncture or electroacupuncture (EA) in treating CIPN. METHODS A literature search was performed on relevant international databases - MEDLINE, Embase, the Allied and Complementary Medicine Databases, and China National Knowledge Infrastructure - as well as Korean databases - the National Digital Science Library, Oriental Medicine Advanced Searching Integrated System, DBpia, and Korean Studies Information Service System. Randomized controlled trials (RCTs) that aimed to treat CIPN symptoms with acupuncture or EA and set not only a control group with a conventional pharmacological treatment or injection, but also a placebo control or sham-acupuncture group, were included. Meta-analysis was conducted to elucidate the efficacy of acupuncture/EA on the basis of symptom score. RESULTS Of the 13 studies included in the literature review, 12 RCTs compared acupuncture and pharmacological treatments. There were 3 EA RCTs, but only 1 RCT compared EA and sham-EA. A total of 832 participants were included in these studies. Five RCTs showed that acupuncture was more effective than pharmacological treatment in terms of efficacy rate. Regarding the risk of bias summary, the quality of included studies was poor. Only 1 study compared the efficacy of EA and sham EA; therefore, the specific efficacy of acupuncture could not be elucidated. CONCLUSION Acupuncture is safe, but the symptom-alleviating effect on CIPN can hardly be determined because of methodological deficiencies of the included studies. In terms of the clinical efficacy rate, acupuncture was more effective than conventional pharmacological treatments. PROSPERO REGISTRATION NUMBER CRD42018111509.

Altered subcallosal and posterior cingulate cortex-based functional connectivity during smoking cue and mental simulation processing in smokers. Prog Neuropsychopharmacol Biol Psychiatry 2020; 97:109772.

Abstract
BACKGROUND Long-term cigarette smoking induces sensitization of incentive salience and conditioning of contextual cues which involves brain function alteration across multiple regions. Understanding how nicotine affects hub-based functional connectivities involved in affective and cognitive function can help us determine the treatment strategy for nicotine dependence. METHOD Functional MRI was conducted on 30 smokers and 30 non-smokers while mentally simulating neutral and smoking hand movements. Smoking cue and mental simulation processing-related changes in functional connectivity strengths of the subcallosal and posterior cingulate cortex (SCC and PCC) with major brain network nodes were examined. RESULTS Compared to non-smokers, smokers showed cue-induced SCC functional connectivities which were enhanced with the intraparietal sulcus and reduced with the medial prefrontal cortex. The PCC activation and functional connectivity enhancements with the anterior insula cortex and rostro-lateral prefrontal cortex was found during smoking mental simulation. The PCC-lateral prefrontal cortex functional connectivity correlated with nicotine dependence severity. CONCLUSION The present results demonstrate that smokers can be identified by cue-induced SCC functional connectivity strength decline and increment in the default mode and dorsal attention network nodes. However, nicotine dependence was associated with smoking mental simulation-related PCC-lateral prefrontal cortex functional connectivity strength, suggesting that the development of nicotine dependence may depend on the strength of coupling between the default mode network and the central executive network at the cognitive level.

Abstract
INTRODUCTION Chemotherapy-induced peripheral neuropathy (CIPN) is one of the major side effects of chemotherapy. Its main symptoms are pain, paresthesia, and numbness. However, the mechanisms underlying the development of CIPN remain unclear and standard treatments have not been established. Recently, there has been a growing interest in various approaches to overcome the limitations of the existing treatments. This study aims to evaluate the efficacy and safety of the concurrent use of two complementary and alternative therapies: electroacupuncture (EA) and Chuna manual therapy (CMT), with pregabalin, which is the conventional pharmacotherapy for neuropathic pain. METHODS/DESIGN This is an open-label, parallel, assessor-blinded randomized controlled trial, which includes 90 patients with colorectal and breast cancer, who developed CIPN. After a 2-week preparation period, the patients are divided into three groups (pregabalin administration group, pregabalin + EA treatment group, and pregabalin + CMT treatment group), treated for approximately 5 weeks and followed-up 4 weeks after treatment. The primary outcome is assessed using the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group Neurotoxicity subscale score (version 4.0) and the secondary outcome is measured using the Quality of Life Questionnaire-CIPN 20-Item Scale (version 3.0) and the quality of life questionnaire (version 3.0) developed by the European Organisation for Research and Treatment of Cancer. Moreover, exploratory efficacy and safety evaluations will be conducted based on the chemotherapy-completion rate and nerve conduction studies.

Abstract
Conventional and herbal drugs are frequently used together to treat many disorders. Samryungbaekchul-san (SRS, a herbal formula) and otilonium bromide (OB, an antispasmodic agent) are widely used to treat diarrhea-predominant irritable bowel syndrome (D-IBS) in Eastern Asian countries. However, there have been no studies on the co-administration of SRS and OB. Therefore, we aimed to preliminarily assess the feasibility of SRS combined with OB for D-IBS treatment in a pilot double-blind, four-arm, parallel-group, randomized controlled trial (RCT), including 80 patients diagnosed with D-IBS according to the Rome III criteria. The patients were randomly assigned to four treatment groups and were administered drugs for eight weeks after a two-week preparatory period. Follow-up was conducted four weeks after the administration period. The primary outcome was evaluated by using a global D-IBS symptom improvement score; no statistically significant difference was observed between the groups. However, multiple logistic regression analysis of primary outcome scores shows that SRS significantly improved D-IBS symptoms (p < 0.05). For secondary outcomes, better results were observed in the SRS + OB group, in terms of symptoms, including abdominal pain, discomfort, frequency of abdominal pain, and stool form than in OB alone or placebo groups (p < 0.05). In conclusion, the co-administration of SRS and OB might be an effective and safe strategy for the treatment of D-IBS. Large-scale RCTs are warranted to further confirm and clarify these findings.

Abstract
The study of metabolomics in natural products using the diverse analytical instruments including GC-MS, LC-MS, and NMR is useful for the exploration of physiological and biological effects and the investigation of drug discovery and health functional foods. Cordyceps militaris has been very attractive to natural medicine as a traditional Chinese medicine, due to its various bioactive properties including anti-cancer and anti-oxidant effects. In this study, we analyzed the metabolite profile in 50% ethanol extracts of C. militaris fruit bodies from three development periods (growth period, matured period, and aging period) using 1H-NMR, and identified 44 metabolites, which are classified as 16 amino acids, 10 organic acids, 5 carbohydrates, 3 nucleotide derivatives, and 10 other compounds. Among the three development periods of the C. militaris fruit body, the aging period showed significantly higher levels of metabolites including cordycepin, mannitol (cordycepic acid), and β-glucan. Interestingly, these bioactive metabolites are positively correlated with antitumor growth effect; the extract of the aging period showed significant inhibition of HepG2 hepatic cancer cell proliferation. These results showed that the aging period during the development of C. militaris fruit bodies was more highly enriched with bioactive metabolites that are associated with cancer cell growth inhibition.

Abstract
INTRODUCTION Chemotherapy-induced peripheral neuropathy (CIPN) occurs in approximately 30% to 40% of patients who receive chemotherapy; however, standardized treatment for CIPN has not yet been developed. Acupuncture is widely used to treat CIPN in Korea, but its efficacy has not been investigated. The purpose of this study is to review the current literature on the efficacy of acupuncture and electroacupuncture (EA) in treating CIPN. MATERIALS AND METHODS We will perform a literature review using the relevant databases, including MEDLINE, Embase, the Allied and Complementary Medicine Databases (AMED), and China National Knowledge Infrastructure (CNKI), as well as Korean databases, including the National Digital Science Library (NDSL), Oriental Medicine Advanced Searching Integrated System (OASIS), DBpia, and Korean studies Information Service System (KISS). Randomized controlled trials describing treatment of CIPN symptoms with acupuncture or EA will be included. The primary outcomes will be scores on a visual analog scale and a numeric rating scale for neuropathic pain. We will also assess the risk of bias by evaluating the available studies using the tools of the Cochrane Collaboration and carry out a meta-analysis. ETHICS AND DISSEMINATION Ethical approvals and patient consent are not necessary because the meta-analysis will be based on published research. We will submit our meta-analysis to a peer-reviewed journal for publication. PROSPERO REGISTRATION NUMBER CRD42018111509.

Abstract
INTRODUCTION Irritable bowel syndrome (IBS), known as a functional and organic gastrointestinal disorder, is a collection of symptoms that occur together and generally include pain or discomfort in the abdomen and changes in bowel movement patterns. Due to the limitations of conventional treatments, alternative IBS treatments are used by many patients worldwide. Samryungbaekchulsan (SRS), a herbal formula, has long been used for alleviating diarrhoea-predominant IBS (D-IBS) in traditional Korean medicine. Otilonium bromide (OB) is an antimuscarinic compound used to relieve spasmodic pain in the gut, especially in IBS. Although herbal formulae and Western drugs are commonly coadministered for various diseases in Korea, few clinical studies have been conducted regarding the synergic effects of these treatments for any disease, including D-IBS. METHODS AND ANALYSIS This trial is a randomised, double-blinded, placebo-controlled, double-dummy, four-arm, parallel study. After a 2-week preparation period, 80 patients with D-IBS will be randomly assigned to one of four treatment groups consisting of SRS (water extract granules, 5 g/pack, three times a day) with OB (tablet form, one capsule three times a day) or their placebos, with treatment lasting for 8 weeks. Post-treatment follow-up will be conducted 4 weeks after the end of treatment. The primary outcome is the finding obtained using the Subject's Global Assessment of Relief method. The secondary outcomes are the severity of symptoms related to D-IBS, determined using a 10-point scale, and the change in symptoms. ETHICS AND DISSEMINATION This trial has full ethical approval of the Ethics Committee of Catholic Kwandong University International St. Mary's Hospital (IS15MISV0033) and the Korean Ministry of Food and Drug Safety (30769). The results of the study will be disseminated through a peer-reviewed journal and/or conference presentations. TRIAL PROTOCOL VERSION IS15MISV0033 version 4.0 (25 July 2016). TRIAL REGISTRATION NUMBER KCT0001621 (approval date: 10 August 2015).

Abstract
The purpose of this study was to classify factors of symptoms and signs, which is the same implication with items of factor, from patients with stroke based on the Traditional Korean Medicine (TKM) theory by using factor analysis, and to find out the inter-relations between factors and patterns. A cross-sectional study was conducted among 2905 patients with stroke in 11 Oriental Medicine hospitals of Korea. Outcome measures comprised patterns decided by TKM doctors considering 44 items and 44 items that were based on inspection, listening and smelling, inquiry, and palpation. Factor analysis was used as statistical method for classifying 44 items, and dominant pattern of the four patterns [Qi deficiency (QD), Fire-heat (FH), Yin deficiency (YD), Dampness-phlegm (DP)] for each factor was determined by Chi-square test. Thirty-three items belonged to some factors, but 11 items did not. 14 factors were extracted. Six factors which had a negative loading were separated, and distinguished using hyphen. The fourteen factors accounted for 9.42%, 6.97%, 5.75%, 4.22%, 4.15%, 3.82%, 3.32%, 3.14%, 2.95%, 2.65%, 2.62%, 2.47%, 2.37% and 2.29% of total variance respectively, and totally 56.14%. In conclusion, there are 10 factors which belong to exclusive pattern, and 9 factors which belong to inter-related pattern. It was statistically found out that there are inter-relation between DP and QD, between DP and FH, between FH and YD, and between YD and QD for stroke patients.

Ranking clinical indicators for stroke pattern identification according to clinical importance in traditional Korean medicine. Int J Clin Exp Med 2014; 7:5146-5157. [PMID: 25664017 PMCID: PMC4307464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2014] [Accepted: 11/24/2014] [Indexed: 06/04/2023]
Abstract
Differences in the value that individual clinicians place on each clinical indicator, when performing pattern identification, can be a significant obstacle in achieving accurate and consistent pattern identification. In this study, we aimed to identify and rank the importance of clinical indicators that correspond to each pattern. During the fundamental study to standardize and objectify the identification of patterns in traditional Korean medicine (TKM) treatment for stroke (the SOPI-Stroke project), we developed the Third Standardization for Pattern Identification (K-SPI-Stroke-III), which includes 44 clinical indicators that belong to one of the four patterns (Dampness-Phlegm, Fire-Heat, Qi deficiency, and Yin deficiency). Between September 2006 and December 2010, a total of 105 TKM doctors from 11 hospitals performed four examinations on 4,012 subjects based on the clinical indicators in the K-SPI-Stroke-III, and they were asked to leave a special mark on the indicators they thought were important, regardless of the number of the indicators. A total of 1,018 patients were included in the study. Among the 44 clinical indicators of the K-SPI-Stroke-III, four indicators were highly significant in differentiating between patterns and the frequency within a pattern. In contrast, another seven indicators were almost useless. Meanwhile, six confounding indicators had outlying values for differentiating between patterns and the frequency within a pattern. In conclusion, the four significant indicators should be actively considered when identifying patterns for strokes in clinical practice. Regarding the six confounding indicators, a further study should be conducted to modify some parts of the current K-SPI-Stroke-III.

Abstract
The aim of this systematic review was to determine the effectiveness of acupuncture for the treatment of whiplash associated disorder (WAD). Twenty databases were searched from their inceptions to Oct. 2013. Randomised clinical trials (RCTs) of acupuncture (AT), electroacupuncture (EA), or dry needling (DN) for the treatment of WAD were considered eligible. The risk of bias was assessed using the Cochrane tool. Six RCTs met the inclusion criteria. Most of the included RCTs have serious methodological flaws. Four of the RCTs showed effectiveness of AT, AT in addition to usual care (UC), AT in addition to herbal medicine (HM) or EA was more effective than relaxation, sham EA, sham EA in addition to HM or UC for conditioned pain modulation (CPM) and alleviating pain. In one RCT, DN in addition to physiotherapy (PT) had no effect compared to sham-DN in addition to PT for the reduction of pain. None of the RCTs showed that AT/EA/DN was more effective than various types of control groups in reducing disability/function. One RCT did not report between-group comparisons of any outcome measures. The evidence for the effectiveness of AT/EA/DN for the treatment of WAD is limited. Therefore, more research in this area is warranted.

An introduction to Chuna manual medicine in Korea: History, insurance coverage, education, and clinical research in Korean literature. Integr Med Res 2013; 3:49-59. [PMID: 28664078 PMCID: PMC5481700 DOI: 10.1016/j.imr.2013.08.001] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2013] [Accepted: 08/21/2013] [Indexed: 11/29/2022] Open
Abstract
The objectives of this study were to summarize the curriculum, history, and clinical researches of Chuna in Korea and to ultimately introduce Chuna to Western medicine. Information about the history and insurance coverage of Chuna was collected from Chuna-related institutions and papers. Data on Chuna education in all 12 Korean medicine (KM) colleges in Korea were reconstructed based on previously published papers. All available randomized controlled trials (RCTs) of Chuna in clinical research were searched using seven Korean databases and six KM journals. As a result, during the modern Chuna era, one of the three periods of Chuna, which also include the traditional Chuna era and the suppressed Chuna era, Chuna developed considerably because of a solid Korean academic system, partial insurance coverage, and the establishment of a Chuna association in Korea. All of the KM colleges offered courses on Chuna-related subjects (CRSs); however, the total number of hours dedicated to lectures on CRSs was insufficient to master Chuna completely. Overall, 17 RCTs were reviewed. Of the 14 RCTs of Chuna in musculoskeletal diseases, six reported Chuna was more effective than a control condition, and another six RCTs proposed Chuna had the same effect as a control condition. One of these 14 RCTs made the comparison impossible because of unreported statistical difference; the last RCT reported Chuna was less effective than a control condition. In addition, three RCTs of Chuna in neurological diseases reported Chuna was superior to a control condition. In conclusion, Chuna was not included in the regular curriculum in KM colleges until the modern Chuna era; Chuna became more popular as the result of it being covered by Korean insurance carriers and after the establishment of a Chuna association. Meanwhile, the currently available evidence is insufficient to characterize the effectiveness of Chuna in musculoskeletal and neurological diseases.

Abstract
BACKGROUND AND PURPOSE Ginsenosides are the main constituents for the pharmacological effects of Panax ginseng. Such effects of ginsenosides including cardioprotective and anti-platelet activities have shown stability and bioavailability limitations. However, information on the anti-platelet activity of ginsenoside-Rp1 (G-Rp1), a stable derivative of ginsenoside-Rg3, is scarce. We examined the ability of G-Rp1 to modulate agonist-induced platelet activation. EXPERIMENTAL APPROACH G-Rp1 in vitro and ex vivo effects on agonist-induced platelet-aggregation, granule-secretion, [Ca(2+) ](i) mobilization, integrin-α(IIb) β(3) activation were examined. Vasodilator-stimulated phosphoprotein (VASP) and MAPK expressions and levels of tyrosine phosphorylation of the glycoprotein VI (GPVI) signalling pathway components were also studied. G-Rp1 effects on arteriovenous shunt thrombus formation in rats or tail bleeding time and ex vivo coagulation time in mice were determined. KEY RESULT: G-Rp1 markedly inhibited platelet aggregation induced by collagen, thrombin or ADP. While G-Rp1 elevated cAMP levels, it dose-dependently suppressed collagen-induced ATP-release, thromboxane secretion, p-selectin expression, [Ca(2+) ](i) mobilization and α(IIb) β(3) activation and attenuated p38(MAPK) and ERK2 activation. Furthermore, G-Rp1 inhibited tyrosine phosphorylation of multiple components (Fyn, Lyn, Syk, LAT, PI3K and PLCγ2) of the GPVI signalling pathway. G-Rp1 inhibited in vivo thrombus formation and ex vivo platelet aggregation and ATP secretion without affecting tail bleeding time and coagulation time, respectively. CONCLUSION AND IMPLICATIONS G-Rp1 inhibits collagen-induced platelet activation and thrombus formation through modulation of early GPVI signalling events, and this effect involves VASP stimulation, and ERK2 and p38(-MAPK) inhibition. These data suggest that G-Rp1 may have therapeutic potential for the treatment of cardiovascular diseases involving aberrant platelet activation.

Abstract
OBJECTIVES The aim of this study was to evaluate the reliability between observers with regard to pulse signs that are observed by Traditional Korean Medicine (TKM) clinicians. METHODS A total 658 patients with stroke who were admitted into Oriental medical university hospitals from February 2010 through December 2010 were included in this study. Each patient was seen independently by 2 experts from the same department for an examination of the pulse signs. Interobserver reliability was measured using three methods: simple percentage agreement, the κ value, and the AC(1) statistic. RESULTS The κ value indicated that the interobserver reliability in evaluating the pulse signs of the subjects ranged from poor to moderate, whereas the AC(1) analysis revealed that agreement between the 2 experts was generally high (with the exception of slippery pulse). The κ value indicated that the interobserver reliability for assessing subjects who garnered the same opinion between the raters was generally moderate to good (with the exceptions of rough pulse and sunken pulse) and that the AC(1) measure of agreement between the 2 experts was generally high. CONCLUSIONS Pulse diagnosis is regarded as one of the most important procedures in TKM, despite the aforementioned limitations. This study reveals that the interobserver reliability in making a pulse diagnosis in stroke patients is not particularly high when objectively quantified. Additional research is needed to help reduce this lack of reliability for various portions of the pulse diagnosis.

Abstract
OBJECTIVE To evaluate the effectiveness of Chuna for the treatment of musculoskeletal pain as reported in Korean literature. METHODS We conducted an electronic literature search using seven Korean databases and manually searched six traditional Korean medicine journals. Risk of bias was assessed with the Cochrane criteria. RESULTS Six randomized controlled trials (RCTs) were included in the study. Compared with standard care, three RCTs suggested favorable effects of Chuna on neck pain due to a hypolordotic cervical spine, low back pain caused by traffic accidents, and low back pain. In contrast, compared with standard care, three RCTs failed to show positive effects on temporomandibular joint disorder, mandibular movement, and neck pain caused by traffic accidents. CONCLUSIONS Currently, the evidence of the effectiveness of Chuna for the treatment of musculoskeletal pain is not convincing. Further rigorously designed trials are warranted to determine its effectiveness.

Abstract
BACKGROUND The present study was conducted to examine the reliability and validity of the 'Korean Standard Pattern Identification for Stroke (K-SPI-Stroke)', which was developed and evaluated within the context of traditional Korean medicine (TKM). METHODS Between September 2006 and December 2010, 2,905 patients from 11 Korean medical hospitals were asked to complete the K-SPI-Stroke questionnaire as a part of project ' Fundamental study for the standardization and objectification of pattern identification in traditional Korean medicine for stroke (SOPI-Stroke). Each patient was independently diagnosed by two TKM physicians from the same site according to one of four patterns, as suggested by the Korea Institute of Oriental Medicine: 1) a Qi deficiency pattern, 2) a Dampness-phlegm pattern, 3) a Yin deficiency pattern, or 4) a Fire-heat pattern. We estimated the internal consistency using Cronbach's α coefficient, the discriminant validity using the means score of patterns, and the predictive validity using the classification accuracy of the K-SPI-Stroke questionnaire. RESULTS The K-SPI-Stroke questionnaire had satisfactory internal consistency (α = 0.700) and validity, with significant differences in the mean of scores among the four patterns. The overall classification accuracy of this questionnaire was 65.2 %. CONCLUSION These results suggest that the K-SPI-Stroke questionnaire is a reliable and valid instrument for estimating the severity of the four patterns.

Abstract
Background The traditional Korean medical diagnoses employ pattern identification (PI), a diagnostic system that entails the comprehensive analysis of symptoms and signs. The PI needs to be standardized due to its ambiguity. Therefore, this study was performed to establish standard indicators of the PI for stroke through the traditional Korean medical literature, expert consensus and a clinical field test. Methods We sorted out stroke patterns with an expert committee organized by the Korean Institute of Oriental Medicine. The expert committee composed a document for a standardized pattern of identification for stroke based on the traditional Korean medical literature, and we evaluated the clinical significance of the document through a field test. Results We established five stroke patterns from the traditional Korean medical literature and extracted 117 indicators required for diagnosis. The indicators were evaluated by a field test and verified by the expert committee. Conclusions This study sought to develop indicators of PI based on the traditional Korean medical literature. This process contributed to the standardization of traditional Korean medical diagnoses.

Abstract
In this report, a simple wet chemical etching of ZnO nanorods to fabricate large area ZnO nanocones is demonstrated. The cone-like morphology formation utilizes anisotropic etching rate on the different crystal planes of ZnO nanorods in an aqueous solution of HCl (HCl [aq]). To form ZnO nanocones, single crystalline ZnO nanorods with a flat hexagonal shape are synthesized on p-Si(100) using hydrothermal method at 90 degrees C and then, are immersed in HCl [aq]. Electron microscopy reveals that the HCl [aq] treatment of ZnO nanorods significantly etched sidewalls of nanorods, resulting in the cone-like morphology formation. The nanocone formation is the most noticeable when the etching occurred in HCl [aq] with a pH of 2.5-3.0 for 5 min etching time. Geometrical analysis using the electron microscopy reveals that the sidewall of a ZnO nanocone have formed a plane indexed as (0-111) after the etching process.
