Electro-acupuncture at acupoint ST36 reduces inflammation and regulates immune activity in Collagen-Induced Arthritic Mice

This study aimed to investigate the anti-inflammatory, anti-arthritic and immuno-regulatory effects of electro-acupuncture (EA) at ST36 on Collagen-induced arthritis (CIA) in mice. Male DBA/1J mice were divided into five groups: Normal, Control, NR (needle retention), EAI and EAII. All mice except those in the normal group were immunized with Collagen II for arthritis induction. Acupuncture needles were inserted into mice ST36 and electrical currents at a frequency of 2 Hz in a continuous rectangular wave form were conducted through the needles for 15 min, 3 times a week. EA treatments were administered for 5 weeks in the EAI group and for 9 weeks in the EAII group. The mice in the NR group were acupunctured in the same manner as the EA groups and the needles were retained for 15 min without electrical stimulation. CIA incidence analysis, ELISA, histological analysis and FACS analysis were performed to evaluate the effect of EA on CIA. EA at ST36 significantly reduced CIA incidence, IL-6, TNF-a, INF-γ, collagen II antibody, IgG and IgM levels in CIA mice serum and prevented knee joint destruction. EA at ST36 also reduced CD69+/CD3e+ cells and CD11a+/CD19+ cells in CIA mice lymph nodes, and CD11b+/Gr1+ cells in CIA mice knee joints. The ratios of CD3e+ cells to CD19+ cells, and CD8+ cells to CD4+ cells were maintained closer to the normal range in the EA groups as compared with the control group or the NR group. EAII was more effective than EAI throughout all the measurements. The NR was effective as well, though less effective than EA. EA at ST36 may have an anti-inflammatory, anti-arthritic and immuno-regulatory effects on CIA in mice. The effectiveness is stronger when EA starts earlier and is applied longer. Needle retention without electrical stimulation may be effective on CIA as well, however less effective than EA. Electrical stimulation and acupoint ST36 may have synergistic effects on CIA

Different contribution of extent of myocardial injury to left ventricular systolic and diastolic function in early reperfused acute myocardial infarction

BACKGROUND: We sought to investigate the influence of the extent of myocardial injury on left ventricular (LV) systolic and diastolic function in patients after reperfused acute myocardial infarction (AMI). METHODS: Thirty-eight reperfused AMI patients underwent cardiac magnetic resonance (CMR) imaging after percutaneous coronary revascularization. The extent of myocardial edema and scarring were assessed by T2 weighted imaging and late gadolinium enhancement (LGE) imaging, respectively. Within a day of CMR, echocardiography was done. Using 2D speckle tracking analysis, LV longitudinal, circumferential strain, and twist were measured. RESULTS: Extent of LGE were significantly correlated with LV systolic functional indices such as ejection fraction (r��=��-0.57, p��<��0.001), regional wall motion score index (r��=��0.52, p��=��0.001), and global longitudinal strain (r��=��0.56, p��<��0.001). The diastolic functional indices significantly correlated with age (r��=��-0.64, p��<��0.001), LV twist (r��=��-0.39, p��=��0.02), average non-infarcted myocardial circumferential strain (r��=��-0.52, p��=��0.001), and LV end-diastolic wall stress index (r��=��-0.47, p��=��0.003 with e') but not or weakly with extent of LGE. In multivariate analysis, age and non-infarcted myocardial circumferential strain independently correlated with diastolic functional indices rather than extent of injury. CONCLUSIONS: In patients with timely reperfused AMI, not only extent of myocardial injury but also age and non-infarcted myocardial function were more significantly related to LV chamber diastolic function.ope

Acral Lentiginous Melanoma Developing during Long-standing Atypical Melanosis: Usefulness of Dermoscopy for Detection of Early Acral Melanoma

Clinical guidelines suggest that suspicious pigmented lesions of the plantar or palmar area require biopsy for early detection of acral melanoma. We present here a case of acral lentiginous melanoma in which various melanocytic atypia was observed at each biopsy site, including focal melanocytic proliferation. We suggest that this atypical melanosis is part of a contiguous phase of invasive tumor growth, which is known as the very early stage of melanoma in situ. In addition, noninvasive dermoscopy has been effective for the early discovery of hidden lesions of acral melanoma

Dining-out behaviors of residents in Chuncheon city, Korea, in comparison to the Korean National Health and Nutrition Survey 2001

Dining-out behavior is associated not only with socio-demographic characteristics such as gender, education, occupation, residence, and marital status, but also with individual preferences, such as eating-out activities, interests, and opinions. We investigated dining-out behaviors and their associated factors. Announcements by health practioners and the Chief of Dong Office were used to recruit 739 residents (217 males and 522 females) in Chuncheon, Korea. Information on the frequency and reasons for eating out, the standards for meal selection, and the overall satisfaction with restaurants, based on taste, nutrition, amount, price, service, sanitation, and subsidiary facilities of restaurants, was obtained through personal interviews with a structured questionnaire. Among all respondents, 46.3% of subjects ate outside of the home once or twice a month, and 33.8% reported that they ate out only a few times a year, or never. This was much higher than the national average of 52.0% as reported by the Korean National Health and Nutrition Survey (KNHNS) in 2001. The frequency of eating out differed significantly according to age (p=0.001), family income (p<0.001), residential area (p<0.001), and educational level (p<0.001). The most common reasons for dining out were meetings (46.7%), followed by special celebrations (15.4%), and enjoyment (11.2%). Korean food (55.3%) was the most frequently selected type of meal when eating out, and food was most often selected based on personal preferences (41.4%) and taste (29.8%); only 5.5% and 7.7% of subjects considered nutrition or other factors (e.g., sanitation), respectively. The results showed that the frequency of eating out for Chuncheon residents was much lower than the national average; in addition, eating-out behaviors depended on the residents' socio-demographic and personal characteristics

Triage Method for Out-of-Hospital Poisoned Patients

The aim of this study was to develop and evaluate a triage method to prevent unnecessary emergency department visits of out-of-hospital poisoned patients. From October 2003 to September 2004, the calls that lay persons gave to the Seoul Emergency Medical Information Center to seek advices on the out-of-hospital poisoned patients were enrolled. We designed a triage protocol that consisted of five factors and applied it to the patients. According to the medical outcomes, we classified the patients into two groups, the toxicity-positive and the toxicity-negative. We arranged the factors on the basis of the priority that was determined in order of the odds ratio of each factor for the toxicity-positive and made a flow chart as a triage method. Then we calculated a sensitivity, specificity, positive predictive value and negative predictive value of the method. We regarded the specificity as the ability of the method and the sensitivity as the safety. A total of 220 patients were enrolled in this study. The method showed a sensitivity, specificity, positive predictive value, and negative predictive value of 99.2%, 53.4%, 76.2%, and 97.9%, respectively. Our triage method prevented 53.4% of the unnecessary emergency department visits of out-of-hospital acutely poisoned patients, safely

Serum Levels of Advanced Glycation End Products Are Associated with In-Stent Restenosis in Diabetic Patients

The formation of advanced glycation end products (AGEs), in various tissues has been known to enhance immunoinflammatory reactions and local oxidant stresses in long standing diabetes. Recently, AGEs have been reported to play a role in neointimal formation in animal models of arterial injury. We attempted to determine whether the serum levels of AGEs are associated with coronary restenosis in diabetic patients. Blood samples were collected from diabetic patients with coronary artery disease undergoing stent implantation and the serum levels of AGEs were analyzed by the fluorescent intensity method. The development of in-stent restenosis (ISR) was evaluated by a 6-month follow-up coronary angiography. A total of 263 target lesions were evaluated, in 203 patients. The ISR rate in the high-AGE (>170 U/ml) group (40.1%) was significantly higher than in the low-AGE group (≤170 U/ml) (19.6%) (p<0.001). Furthermore, multivariate analysis revealed that a high level of serum AGEs is an independent risk factor for the development of ISR (odds ratio, 2.659; 95% CI, 1.431-4.940; p=0.002). The serum levels of AGEs constitute an excellent predictive factor for ISR, and should be one of the guidelines for medical therapy and interventional strategy to prevent ISR in diabetic patients

The effectiveness of moxibustion for the treatment of functional constipation: a randomized, sham-controlled, patient blinded, pilot clinical trial

<p>Abstract</p> <p>Background</p> <p>Moxibustion is an ancient traditional medicine using burning mugworts to stimulate acupuncture points. The aim of this study was to investigate the safety and efficacy of moxibustion for the treatment of constipation using a randomized, sham-controlled, participant-blinded, pilot trial.</p> <p>Methods</p> <p>Twenty-six participants (identified with either qi (vital energy) deficiency or qi excess syndrome) were randomly divided into either a moxibustion or sham group. Participants were treated with real or sham moxibustion at 4 acupuncture points, ST23 and ST27, bilaterally, 3 times per week for four weeks. The primary outcome was the frequency of defecations; secondary outcomes were the Bristol stool form scale (BSS) and the constipation assessment scale (CAS).</p> <p>Results</p> <p>Of the 26 participants that were randomized, 24 completed the study. Defecation frequency, BSS, and CAS showed no difference between the moxibustion and sham groups. The differences were -0.25 (95% CI: -2.08, 1.58, p = 0.78), -1.22 (95% CI: -2.7, 0.26, p = 0.1), 0.91 (95% CI: -1.46, 3.28, p = 0.44) in defecation frequency, BSS, CAS, respectively. The defecation frequency increased from an average of 3.3 to 4.6 times per week in the moxibustion group (1.5[-0.5, 2], <it>p </it>= 0.06) and from 2.7 to 3.7 stools per week in the sham group (1[-1, 2], <it>p </it>= 0.15) after four weeks of treatment. The difference between participants with a deficiency or an excess syndrome, determined based on assessment of sweat, facial features, pain, body energy, and pulse type, was significant in only defecation frequency. The difference was 3.3 (95% CI: 0.41, 6.19, <it>p </it>= 0.03).</p> <p>Conclusion</p> <p>Moxibustion treatment appears safe, but showed no positive effect on constipation. The effectiveness of moxibustion treatment may depend on the syndrome pattern, and further long-term studies with a larger number of subjects are warranted.</p> <p>Trial registration</p> <p>Clinical Research Information Service, KCT0000168</p

Anti-inflammatory and Immune-regulatory Effects of Subcutaneous Perillae Fructus Extract Injections on OVA-induced Asthma in Mice

Perillae fructus (perilla seed) is a traditional medicinal herb used to treat bronchial asthma in Oriental medical clinics. ST36 is one of the most widely used acupuncture points, particularly for immune system regulation. Injection of an herbal extract into an acupuncture point (herbal acupuncture) is a therapeutic technique combining both acupuncture and herbal treatment. Perillae fructus extract was injected subcutaneously (Perillae fructus herbal acupuncture; PF-HA) at acupoint ST36 of OVA-induced asthmatic mice. The lung weight, bronchoalveolar fluid (BALF) cell count, the number of CCR3+, CD11b+, CD4+ and CD3e+/CD69+ cells in the lung, and the level of IgE, IL-4, IL-5 and IL-13 in BALF and serum were then measured. RT-PCR was used to measure the mRNA expression of IL-4, IL-5, IL-13 and TNF-α in the lung. Lung sections were analyzed histologically. PF-HA significantly reduced lung weight, the number of inflammatory cells in the lung and BALF, the levels of IgE and Th2 cytokines in BALF and serum, mRNA expression of Th2 cytokines in the lung, and pathological changes in lung tissue. Our results suggest that PF-HA may have an anti-inflammatory and immune-regulatory effect on bronchial allergic asthma by restoring the Th1/Th2 imbalance in the immune system and suppressing eosinophilic inflammation in airways

Differential Relationship between Metabolic Syndrome Score and Severity of Coronary Atherosclerosis as Assessed by Angiography in a Non-Diabetic and Diabetic Korean Population

Whether the metabolic syndrome (MetS) has prognostic value for coronary artery disease (CAD) beyond its individual components is controversial. We compared the relationship between the number of MetS components and CAD severity as assessed by angiography in non-diabetic and diabetic subjects. We consecutively enrolled 527 patients who underwent their first coronary angiography. Patients were divided into four groups according to the number of MetS components: 0/1, 2, 3, and 4/5. A coronary atherosclerosis score was used to quantify the extent of atherosclerotic involvement. The relationship between the MetS score and angiographic CAD severity or clinical presentation was compared between non-diabetic and diabetic subjects. Individuals with the MetS (n = 327) had a higher prevalence of CAD (60% vs 32%, P < 0.001), multi-vessel disease (34% vs 16%, P < 0.001), and acute coronary syndromes (49% vs 26%, P < 0.001) than those without the MetS. In the non-diabetic group, atherosclerosis score increased with the MetS score (1.0 ± 2.1, 2.0 ± 2.9, 2.8 ± 2.9, and 3.6 ± 3.9, P < 0.001) whereas there was no significant difference in the diabetic group (0.5 ± 1.0, 5.2 ± 4.7, 4.2 ± 2.9, and 4.4 ± 3.5, P = 0.102). The MetS score is related to CAD severity in non-diabetic patients but the association between the MetS score and angiographic CAD severity may be obscured in the presence of diabetes
