RESUMEN

OBJECTIVES: A vertebral compression fracture (VCF) is characterized by back pain and fracture of a vertebral body on spinal radiography. VCFs of the thoraco lumbar spine are common in the elderly. In general, appropriate analgesics should be prescribed to reduce pain and, thus, promote early mobilization. The ideal treatment approach for VCFs has not been determined. In Korea, acupuncture and herbal medication have been used to treat VCFs for many years. There is empirical evidence that acupuncture might benefit patients with a VCF. However, no randomized, controlled, clinical trials evaluating the efficacy and the safety of acupuncture for treating a VCF have been published. Therefore, we designed a randomized, controlled, pilot, clinical trial to obtain information for the design of a further full scale trial. METHODS: A five week protocol for a randomized, controlled, pilot, clinical trial is presented. Fourteen patients will be recruited and randomly allocated to two groups: a control group receiving interlaminar epidural steroid injections once a week for three weeks, and an experimental group receiving interlaminar epidural steroid injections plus acupuncture treatment (three acupuncture sessions per week for three weeks, nine sessions in total). The primary outcomes will be the pain intensity (visual analogue scale and PainVision(TM) system). The secondary outcome measurements will be the answers on the short form McGill pain questionnaire and the oswestry disability index. Assessments will be made at baseline and at one, three, and five weeks. The last assessment (week five) will take place two weeks after treatment cessation. This study will provide both an indication of feasibility and a clinical foundation for a future large scale trial. The outcomes will provide additional resources for incorporating acupuncture into existing treatments, such as nonsteroidal anti-inflammatory medications, narcotics and vertebral augmentation. This article describes the protocol.

RESUMEN

BACKGROUND: In recent years, the interest in Qigong as an alternative therapy has grown following reports of its ability to regulate psychological factors in cancer patients. This is a case series to evaluate the outcome measures of Qigong when used as an adjunct to standard medical care to treat insomnia and stress in cancer patients. PATIENTS AND METHODS: The Qigong program was applied to four cancer patients with insomnia, stress, and anxiety. The program consisted of 30-min sessions involving exercise, patting of the 12 meridians, and spontaneous breathing exercises three times a week for a period of 4 weeks. The Pittsburgh Sleep Quality Index was measured as the primary outcome, while the Stress Scale, the State-Trait Anxiety Inventory, and the Functional Assessment Cancer Therapy-General determined the secondary outcomes. Insomnia, stress, and anxiety levels were examined weekly, while quality of life was examined on the first visit and the last visit. RESULTS: The Pittsburgh Sleep Quality Index and Stress Scale scores were reduced after conduct of the Qigong program. CONCLUSION: This study could provide a better understanding of Qigong's influence on insomnia and stress in cancer patients. However, a larger controlled trial should be conducted to confirm these findings.

RESUMEN

OBJECTIVE: To collect preliminary data on the effects of Saam acupuncture with regard to the immunity in cancer patients. METHODS: Ten cancer patients were analyzed for improvements in immunity. Acupuncture was applied at the 5 acupuncture points, Jingqu (LU 8), Zutonggu (BL 66), Yanggu (SI 5), Yangchi (TE 4), and Zhongwan (CV 12) for 2 weeks with 4 sessions. We assessed the effect of Korean Saam acupuncture on the immune system in cancer patients by measuring particular blood cell subsets, including CD3+, CD4+, CD8+, CD19+, and CD56+ cells, as well as total white blood cell count, absolute neutrophil count, and fatigue score. The measurement was performed before and after acupuncture and at a 2-week follow-up. RESULTS: There was a statistically significant increase in the number of CD3+ (P = 0.023) and CD8+ cells (P < 0.001) and T-cell subsets, as well as a decrease in the fatigue severity scale (FSS) score (P = 0.001) after Saam acupuncture using the 5 acupoints. CONCLUSION: Acupuncture may improve the immune system by increasing the counts of a few immune cells and relieve fatigue in cancer patients by decreasing FSS scores. Although this was a non-controlled study, it constitutes preliminary research investigating the potential effects of Saam acupuncture in increasing the counts of several immune cells in cancer patients.

RESUMEN

BACKGROUND: Cold hands sensation is a common disorder within the Korean population. Many Korean family physicians believe that it is a mild early manifestation of Raynaud's phenomenon (RP), or may be related to RP. RP is characterized by reversible digital vasospasm provoked by cold temperatures and/or emotional stress, and doctors often prescribe medications that are used in treatment of RP for subjects with cold hands. However, this has not shown a clear benefit, and these medications can cause unwanted side effects. It is also reported that traditional Korean medicine, including acupuncture, is widely used to treat cold hands, although the current level of evidence for this approach is also poor and to date, there have been no published randomized controlled clinical trials (RCTs) evaluating the efficacy and safety of acupuncture for cold hands. We have therefore designed a pilot RCT to obtain information for the design of a further full-scale trial. METHODS/DESIGN: The proposed study is a five-week pilot RCT. A total of 14 subjects will be recruited and randomly allocated to two groups: an acupuncture plus medication group (experimental group) and a medication-only group (control group). All subjects will take nifedipine (5 mg once daily) and beraprost (20 mg three times daily) for three weeks. The experimental group will receive additional treatment with three acupuncture sessions per week for three weeks (nine sessions total). The primary outcome will be measured using a visual analogue scale. Secondary outcomes will be measured by blood perfusion in laser Doppler perfusion imaging of the hands, frequency and duration of episodes of cold hands, and heart rate variability. Assessments will be made at baseline and at one, three, and five weeks thereafter. DISCUSSION: This study will provide an indication of the feasibility and a clinical foundation for a future large-scale trial. TRIAL REGISTRATION: This study was registered at Korean Clinical Research Information Service (CRIS) registry on 5 August 2013 with the registration number #KCT0000817.

RESUMEN

BACKGROUND: Spondylolisthesis is the major cause of refractory low back pain. There are many studies of the surgical treatment of spondylolisthesis, but few of conservative treatments. There is also no optimal conservative treatment protocol, however, low back pain caused by low-grade spondylolisthesis is controlled with non-surgical pain management. Acupuncture has become a useful method for treating low back pain, but there has not been any study of its efficacy in relation to spondylolisthesis. This study was designed to establish the feasibility of a randomized controlled trial and the safety of acupuncture for low back pain due to low-grade spondylolisthesis. METHODS/DESIGN: The study is a randomized controlled pilot clinical trial of five weeks duration. Fourteen patients will be recruited and randomly allocated to two groups: an acupuncture plus interlaminar epidural steroid injection group (experimental group), and an interlaminar epidural steroid injection group (control group). All patients will be administered an interlaminar epidural steroid injection once a week for three weeks (three injections in total), but only the experimental group will receive additional treatment with three acupuncture sessions a week for three weeks (nine acupuncture sessions in total). The primary outcome will be measured by the visual analogue scale (VAS). Our primary end point is three-week VAS. The secondary outcome will be measured using the PainVision system, the short-form McGill Pain Questionnaire, and the Oswestry Disability Index. Assessments will be made at baseline and at one, three and five weeks thereafter (that is, the five-week assessment will be made two weeks after treatment cessation). DISCUSSION: This randomized controlled pilot trial will inform the design of a further full-scale trial. The outcomes will provide some resources for incorporating acupuncture into existing pain management methods such as interlaminar epidural steroid injection in low-grade spondylolisthesis. TRIAL REGISTRATION: This trial is registered with the US National Institutes of Health Clinical Trials registry: NCT01909284.

RESUMEN

AIMS: The purposes of this study were to determine whether Cervi Pantotrichum Cornu (CPC) has osteogenic activities in human osteoblastic MG-63 cells and to investigate the underlying molecular mechanism. MAIN METHODS: The effects of CPC on alkaline phosphatase activity, collagen synthesis, and calcium deposits were measured. The COL1A1, ALPL, BGLAP, and SPP1 expressions were measured by real-time PCR. Phosphorylated MAP kinases (ERK1/2, JNK1/2, p38, ELK1, and cJUN) were studied by western blot analysis. The involvement of MAPK pathway in osteogenic gene expressions was determined by using each selective MAPK inhibitor (PD98059, SP600125, and SB203580). KEY FINDINGS: CPC increased alkaline phosphatase activity, collagen synthesis, and calcium deposits. CPC activated ERK1/2, JNK1/2, p38, and ELK1 phosphorylation except cJUN. CPC increased the COL1A1, ALPL, BGLAP, and SPP1 gene expressions. The elevated COL1A1 and BGLAP expressions were inhibited by PD98059, SP600125 or SB203580. The elevated ALPL expression was blocked by SB203580. The elevated SPP1 expression was inhibited by SP600125 or SB203580. CPC increased COL1A1 and BGLAP expressions via ERK1/2, JNK1/2, and p38 MAPKs pathways and SPP1 expression via JNK1/2 and p38 pathways. p38 pathway is needed for ALPL expression. SIGNIFICANCE: These results imply that MAPK signaling pathway is an indispensable factor for bone matrix genes expression of CPC in MG-63 human osteoblast-like cells.

RESUMEN

In this study, genetic analysis was conducted to investigate the association of angiotensin I converting enzyme (ACE) gene polymorphism with clinical phenotype based on differentiation-syndrome of bronchial asthma patients. Differentiation-syndrome is a traditional Korean medicine (TKM) theory in which patients are classified into a Deficiency Syndrome Group (DSG) and an Excess Syndrome Group (ESG) according to their symptomatic classification. For this study, 110 participants were evaluated by pulmonary function test. Among them, 39 patients were excluded because they refused genotyping. Of the remaining patients, 52 with DSG of asthma (DSGA) and 29 with ESG of asthma (ESGA), as determined by the differentiation-syndrome techniques were assessed by genetic analysis. ACE insertion/deletion (I/D) polymorphism analysis was conducted using polymerase chain reaction (PCR). Student's t, chi-square, Fisher and Hardy-Weinberg equilibrium tests were used to compare groups. No significant differences in pulmonary function were observed between DSGA and ESGA. The genotypic frequency of ACE I/D polymorphism was found to differ slightly between DSGA and ESGA (P = .0495). However, there were no significant differences in allelic frequency observed between DSGA and ESGA (P = .7006, OR = 1.1223). Interestingly, the allelic (P = .0043, OR = 3.4545) and genotypic (P = .0126) frequencies of the ACE I/D polymorphism in female patients differed significantly between DSGA and ESGA. Taken together, the results presented here indicate that the symptomatic classification of DSGA and ESGA by differentiation-syndrome in Korean asthma patients could be useful in evaluation of the pathogenesis of bronchial asthma.

RESUMEN

A body of evidence indicates obesity is an inflammatory state with chronic activation of the immune system. The interleukin 4 receptor (IL4R) single nucleotide polymorphism (SNP), rs 180275 (1902A>G) is well recognized for its association with atopy and other inflammatory diseases. We assessed the possible association of rs 180275 and rs 1805010 with obesity in Korean population. Study subject consisting of 876 Koreans were divided into three groups: subjects with 1) BMI<25, 2) BMI between 25 and 27, and 3) BMI>27. Analyses of genotype distributions and allele frequencies of study subjects revealed that rs 180275 polymorphism was associated with an increase in BMI in Korean population (P=0.009 and 0.011, respectively) while no association was found between rs 1805010 and obesity. We observed significantly lower percentage of rs 180275 G allele in subjects with BMI>27 than in subjects with BMI< or =27 (9.9% vs. 16.0%). Logistic regression analysis revealed that the odds ratio (OR) for an increase in BMI associated with the G vs. A allele was 0.57 [95% Confidence interval (CI)=0.39-0.85, p=0.002], which strongly implicates the protective role of rs 180275 G allele against an increase in BMI. Haplotype analysis revealed no association was present between rs 180275 and rs 1805010 polymorphisms. The frequency of rs 180275 G allele is significantly lower in subjects with BMI>27, suggesting the protective role of IL4R rs 180275 G allele against an increase in BMI in Korean population.

RESUMEN

BACKGROUND: This study was designed to investigate the involvement of inducible nitric oxide synthase (iNOS) in electroacupuncture (EA)-induced analgesia. METHODS: Two and 100 Hz EA stimulation were applied at acupoint ST 36 (Zusanli) in iNOS knockout mice (n = 28). Needles were inserted 5 mm in depth in ST36. After insertion, the needles were fixed in situ with adhesive tape. EA was applied after the basal threshold determination. The EA parameters were set as follows: constant square wave current output (pulse width: 0.6 ms at 2 Hz and 0.2 ms at 100 Hz) and 2 mA intensities. EA was performed for 30 minutes and tail-flick latencies (TFLs) were evaluated every 15 minutes for 1 hour. RESULTS: In 2 Hz EA stimulation, the tail-flick response (TFR) of wild-type mice for durations of 0, 15, 30, 45 and 60 minutes were 2.70 +/- 0.26, 4.19 +/- 0.37, 4.17 +/- 0.34, 3.57 +/- 0.27 and 3.39 +/- 0.32 seconds of TFLs. Meanwhile, iNOS -/- mice showed 4.10 +/- 0.33, 4.77 +/- 0.24, 5.26 +/- 0.30, 4.48 +/- 0.33 and 5.00 +/- 0.41 seconds of TFLs. In 100 Hz EA stimulation, the TFR of wild-type mice were 3.01 +/- 0.24, 4.67 +/- 0.31, 4.76 +/- 0.25, 4.04 +/- 0.45 and 4.26 +/- 0.30 seconds of TFLs. The iNOS -/- mice were 4.33 +/- 0.16, 5.29 +/- 0.28, 5.06 +/- 0.35, 4.52 +/- 0.17 and 4.80 +/- 0.28 seconds of TFLs. Wild-type mice exhibited 63.9% increase in TFL compared to the baseline after 2 Hz EA, whereas the iNOS knockout mice exhibited 32.9% increase in TFL. The TFL after 100 Hz EA showed similar trends: 66.5% increase in TFL in wildtype mice and 18.3% increase in the iNOS knockout mice. CONCLUSION: The present findings suggested that iNOS may play a crucial role in both low- and high-frequency EA-induced analgesic effects.

RESUMEN

BACKGROUND: Traditional Korean medicine (TKM) therapy of scalp and penetration acupuncture has been used for the treatment of stroke in Korea. This study investigated the efficacy of scalp and penetration acupuncture in combination with TKM medication. METHODS: Twenty-four stroke patients were enrolled in the program. Control group (n = 12) received herbal medicines (Baepungtang, Sopungtang or Sosokmyeongtang) and conventional body acupuncture. Treatment group (n = 12) received scalp and penetration acupuncture in addition to herbal medicines and conventional body acupuncture. Improvements in the motor functions were scored by the modified Barthel index (MBI). RESULTS: After 4 weeks of treatment, statistical analysis showed significant improvement in the MBI scores for both groups. Significant difference in the MBI scores between two groups, however, was not observed. CONCLUSION: The supportive effect of scalp and penetration acupuncture in the treatment of stroke needs further investigation.

RESUMEN

Pinelliae Rhizoma has been used traditionally in Korea to promote the liver Qi activity and the function of the digestive system. We investigated whether the Pinelliae Rhizoma herbal-acupuncture solution (PRHS) would induce cell-death on SNU-17, human cervical cancer cells. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to investigate the cytotoxicity of PRHS. The cell death was identified as apoptosis with 4, 6-diamidineo-2-phenylindole (DAPI) staining, and terminal deoxy-nucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL) assay. PRHS could induce apoptosis of SNU-17 via Bax-related caspase-3 activation. The expressions of both Bax, a pro-apoptotic gene, and caspase-3, an apoptotic gene, were increased. The results might provide the experimental data for the clinical use of Pinelliae Rhizoma on cervical cancer.

RESUMEN

The interleukin 4 receptor (IL4R) polymorphism Q576R (rs 180275) has been well known to be associated with atopy and other inflammatory diseases. A single nucleotide polymorphism (SNP) A > G transition potentiates the binding specificity of the adjacent tyrosine residue. In this study we investigated the possible relationship between sudden deafness (SD) and IL4R polymorphism Q576R in 97 Korean SD patients and 613 controls using pyrosequencing method. The odds ratio (OR) for SD associated with the G vs. A allele was 2.58 [P < 0.0001, 95% confidence interval (CI) = 1.84-3.60]. We then sub-grouped SD into Tinnitus positive (+) and Tinnitus negative (-). G allele in Tinnitus (+) is significantly associated with the development of Tinnitus (+) [X(2) = 32.02, P < 0.0001, OR (95% CI) = 2.74 (1.91-3.93)] but not with Tinnitus (-). Taken together these results suggest that G allele could be a risk factor for SD.

RESUMEN

Locating acupuncture points reliably and reproducibly is indispensable for the scientific research of acupuncture and for assuring the best care of patients. Unreliable point location can produce confounding results for acupuncture research and clinical practice. Two traditional methods of point location are currently used, directional (F-cun) and proportional (B-cun) methods, which are collectively called the cun measurement system. Reports have been published on the validity of the cun measurement system in Australian subjects; however, as acupuncture originated in ancient East China, it is possible that anthropometric data may differ in Asian people and other races. Therefore, we measured anthropometric data according to the cun measurement system in contemporary Korean patients. The F-cun measurements were significantly different from the B-cun measurements and varied significantly according to the arbitrarily selected F-cun standard. In addition, we observed further differences of F-cun measurements in the extremities of obese subjects. We concluded that the F-cun method is unreliable and that further research should be conducted to determine a more accurate point-locating method primarily based on the B-cun method.

RESUMEN

This study was performed to determine whether two ginseng species (Panax ginseng and Panax quinquefolius) can be identified by genetic analysis and to verify pyrosequencing analysis, which was used to assess genetic variation. The pyrosequencing results constituted clear data. Panax quinquefolius showed a very different pattern than Panax ginseng. Pyrosequencing analysis might be able to identify the Panax species.

RESUMEN

This study was performed to determine if Akebia and Aristolochia species (Akebia quinata Decaisne and Aristolochia manshuriensis Kom.) could be identified by genetic analysis of Pyrosequencing method, which is used to assess genetic variation. The Pyrosequencing results of Akebia and Aristolochia species showed different patterns. The Pyrosequencing analysis of A. quinata Decaisne was very different compared with that of A. manshuriensis Kom. Pyrosequencing analyses might be able to identify the Akebia and Aristolochia species.

RESUMEN

We investigated a source coherence effect on the measurement of the optical fiber nonlinear coefficient by use of dual optical frequencies. We produced coherent and incoherent dual optical frequencies with a self-heterodyne Mach-Zehnder interferometer with and without a delay line, respectively. Our measurement results included both an electrostrictive and a Kerr nonlinear coefficient because of the low modulation frequency. Comparing the coherent case with an incoherent case, we obtained a nonlinear coefficient that was more than 3% higher in the coherent case.

RESUMEN

BACKGROUND: Vitiligo is a common disease characterized by cutaneous white maculae due to loss of melanocytes. It is a polygenic disease, however, the exact pathogenesis of vitiligo is not yet known. The estrogen receptor (ESR) 1 gene was selected as a candidate gene because some researchers treated vitiligo successfully with the steroid-thyroid hormone mixture containing estrogen. Furthermore ESR was expressed in the melanocytes which have an important role in the pigmentation. The polymorphisms of ESR1 gene in vitiligo patients was not reported yet. OBJECTIVE: To determine whether polymorphisms of ESR1 gene were associated with susceptibility to vitiligo patients in Korean population. METHODS: We conducted case-control association study of vitiligo patients (120) and healthy controls (254). Genotypes of ESR1 gene (intron 1 C/T, exon 4 C/G, and exon 8 A/G) were determined by polymerase chain reaction followed by restriction enzyme digestion. RESULTS: Intron 1 T/C allele frequency was significantly different between patients and controls (P = 0.034). Intron 1 T/C genotype distribution (P = 0.021) and allele frequency (P = 0.013) were different between female vitiligo patients and female controls. Intron 1 T/C allele frequency showed significantly difference between generalized type of vitiligo patients and controls (P = 0.044). Genotype distributions and allele frequencies of exon 4 C/G and exon 8 A/G polymorphisms were not different between patients and controls. CONCLUSION: The present study suggests that ESR1 may be a possible risk factor for female or generalized type of vitiligo patients.

RESUMEN

Enhanced release of proinflammatory cytokines may contribute to the pathogenesis of ischemic stroke. Interleukin-1 receptor antagonist (IL-1Ra) is an anti-inflammatory cytokine, and tumor necrosis factor (TNF)-alpha and IL-1beta are proinflammatory cytokine. To determine the role of cytokines in genetic susceptibility to ischemic stroke, we genotyped ischemic stroke patients (n = 152) and the healthy control subjects (n = 165) for IL-1Ra, TNF-alpha and IL-1beta polymorphism by polymerase chain reaction-restriction fragment length polymorphism methods. The analysis shown the association of IL1RN*1, IL1RN*2 allele (IL1RN*1, OR=0.44, P = 0.0206 IL1RN*2, OR=2.90, P = 0.0141) and TNF1, TNF2 allele (TNF1, OR=2.16, P = 0.0225; TNF2, OR=2.16, P = 0.0225) to ischemic stroke. However, the genetic polymorphism of IL-1beta was not associated with ischemic stroke. Our results suggest that IL-1Ra and TNF-alpha gene polymorphism is associated with the susceptibility to ischemic stroke.

RESUMEN

The protective effect of Acanthopanax senticosus (AS) against ethanol (EtOH)-induced apoptosis of the human neuroblastoma cell line SK-N-MC was investigated via 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, flow cytometric analysis, DNA fragmentation assay, reverse transcription-polymerase chain reaction (RT-PCR), and caspase-3 assay. It was shown that cells treated with EtOH exhibit classical apoptotic features, while cells pre-treated with Acanthopanax senticosus prior to EtOH exposure showed decreased occurrence of apoptotic features. In addition, Acanthopanax senticosus pre-treatment was shown to inhibit EtOH-induced increase in caspase-3 mRNA expression and activity. These results suggest that Acanthopanax senticosus may exert a protective effect against EtOH-induced apoptosis of human neuroblastoma cells.
