Acupuncture to treat asymptomatic hyperuricemia: A protocol for systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Hyperuricemia (HUA) plays an important role in metabolic syndrome, cardiovascular disease, and kidney disease. HUA without resulting gout is referred to as asymptomatic HUA. The purpose of the present systematic review protocol is to provide methods to assess the effectiveness and safety of acupuncture-based treatment for asymptomatic HUA. METHODS: To identify randomized controlled trials (RCTs) involving acupuncture-based treatment for asymptomatic HUA, a search will be carried out using the following eight electronic databases: MEDLINE, EMBASE, Cochrane Library, Korea Med, Oriental Medicine Advanced Searching Integrated System, Korean Studies Information Service System, China National Knowledge Infrastructure, and Japanese Institutional Repositories Online. Manual search and email contact with the author will also be conducted if necessary. Studies will be selected based on predefined criteria and summarized data regarding study participants, interventions, control groups, outcome measures, side effects, and risk of bias. No language restrictions will be imposed. Studies that evaluated any type of acupuncture will be eligible for inclusion, and the primary outcome will be the blood uric acid level. The methodological quality of the included RCTs will be assessed using the Cochrane risk of bias tool. RESULTS: The present study will evaluate the efficacy and safety of acupuncture to treat HUA. CONCLUSION: Our findings will establish the evidence for acupuncture-based treatment of HUA and will be informative for patients with HUA, clinicians, policy makers, and researchers.

Efficacy, safety, and cost-effectiveness analysis of adjuvant herbal medicine treatment, Palmijihwang-hwan, for chronic low back pain: a study protocol for randomized, controlled, assessor-blinded, multicenter clinical trial.

BACKGROUND: Low back pain is a common symptom and continuous or recurrent pain results in chronic low back pain (CLBP). While many patients with CLBP have tried various treatments, complementary and alternative medicine including acupuncture and herbal medicine is one of the commonly used treatments. Palmijihwang-hwan is a herbal medicine used frequently in clinical practice but there has been no report of the efficacy, safety, or cost-effectiveness analysis of Palmijihwang-hwan for CLBP. METHODS: This study is a randomized, assessor-blinded, multicenter, clinical trial with two parallel groups. Four Korean medicine hospitals will recruit 84 participants and randomly allocate them into the control or treatment group in a 1:1 ratio. The control group will receive acupuncture treatment at 11 local and 4 distal acupuncture points for 20 min twice a week for 6 weeks. The treatment group will receive the same acupuncture treatment as the control group and also take Palmijihwang-hwan for 6 weeks. The primary outcome will be the change in visual analog scale (VAS) score between baseline (visit 1) and completion of the intervention (visit 12), and secondary outcomes will be pain-related clinical relevance (minimal clinical important difference or the proportion of the participants who decrease more than 30, or 50% on VAS), disability (Roland and Morris Disability Questionnaire), quality of life (EuroQol-5D), global assessment (Patient Global Impression of Change), and economic analysis (cost-effectiveness and cost-utility analysis). Additionally, safety will be assessed. DISCUSSION: The results of our study will provide the clinical evidence about the efficacy, safety, and cost-effectiveness analysis of Palmijihwang-hwan for CLBP. There will be a chance to provide multiple subdivided influence of this treatment with various outcome measures, but lack of placebo is our limitation.

Clinical outcomes after local anesthesia with monitored anesthesia care during thyroidectomy and selective neck dissection: a randomized study.

Although thyroidectomy under local anesthesia with monitored anesthesia care (LA-MAC) has been reported, reports of neck dissections beyond level VI under LA-MAC in patients with thyroid cancer are rare. We aimed to analyze clinical data and patient satisfaction levels during thyroidectomy and selective neck dissection by comparing LA-MAC and general anesthesia (GA) in adult patients undergoing these surgeries for thyroid cancer. The 60 enrolled patients comprised 50 patients that underwent thyroidectomy and 10 that underwent selective neck dissection; 30 underwent thyroidectomy (n = 25) or selective neck dissection (n = 5) under LA-MAC and 30 (matched patients) underwent thyroidectomy (n = 25) or selective neck dissection (n = 5) under GA. Complaints of postoperative nausea, vomiting, throat discomfort, and voice changes were significantly fewer in the LA-MAC group than in the GA group. Postoperative pain, odynophagia, dyspnea, and patient satisfaction levels were not significantly different between groups. In the thyroidectomy group, postoperative nausea, vomiting, throat discomfort, and voice changes were less common with LA-MAC, whereas postoperative pain, odynophagia, dyspnea, and patient satisfaction levels were similar for both anesthesia methods. The selective neck dissection group showed no differences between the two anesthesia methods. No postoperative complications were reported in all patients. Our results suggest that LA-MAC can be routinely used for select cases of thyroidectomy and is feasible for selective neck dissection beyond level VI with regard to postoperative discomfort, patient satisfaction levels, and safety. However, further investigations are necessary to clarify these findings.

The standardized BHH10 extract, a combination of Astragalus membranaceus, Cinnamomum cassia, and Phellodendron amurense, reverses bone mass and metabolism in a rat model of postmenopausal osteoporosis.

Jasin-hwan-gagambang (BHH10), a modified prescription of Jasin-hwan, contains Astragalus membranaceus, Cinnamomum cassia, and Phellodendron amurense, and it has been traditionally used to treat osteoporosis and other inflammatory diseases. In this study, we systematically investigated the protective effects of BHH10 in ovariectomy (OVX)-induced rats. Sprague-Dawley rats were randomly divided into sham and OVX subgroups. The rats in the OVX group were treated with vehicle, BHH10, alendronate (ALN), and 17ß-estradiol (E2). BHH10 treatment significantly inhibited OVX-induced increases in body weight and uterus atrophy. In addition, it significantly increased the bone mineral density (BMD) and prevented a decrease in trabecular bone volume, connectivity density, trabecular number, thickness, and separation at the total femur and femur neck. The OVX rats showed significant decreases in the serum levels of calcium and phosphorous and significant increases in the serum levels of cholesterol, low-density lipoprotein cholesterol, alkaline phosphatase, osteocalcin, C-telopeptide type 1 collagen, and bone morphogenetic protein-2. These changes were significantly reduced to near sham levels by administration of BHH10 to OVX rats. BHH10-treated rats had a greater bone mass, a better structural architecture of the bone, and higher levels of biochemical markers of the bone than did the ALN-treated or E2-treated rats. These results suggest that BHH10 reverses osteoporosis in OVX rats by stimulating bone formation or regulating bone resorption and is not associated with toxicity.

Formononetin accelerates wound repair by the regulation of early growth response factor-1 transcription factor through the phosphorylation of the ERK and p38 MAPK pathways.

Formononetin, a phytoestrogen from the root of Astragalus membranaceus, is used as a blood enhancer and to improve blood microcirculation in complementary and alternative medicine. The present study investigated the influence of formononetin on the expression of early growth response factor-1 (Egr-1) and growth factors contributing to wound healing. Formononetin significantly increased growth factors such as transforming growth factor-beta 1 (TGF-ß1), vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF) and basic fibroblast growth factor (bFGF) in human umbilical vein endothelial cells (HUVECs). Formononetin also increased the expression of Egr-1 transcription factor by 3.2- and 10.5-fold, compared with recombinant VEGF(125) in HUVECs. The formononetin-mediated 12%-43% increase induced endothelial cell proliferation and recovered the migration of wounded HUVECs. In an ex vivo angiogenesis assay, formononetin produced a larger capillary sprouting area than produced using recombinant VEGF(125). Cell proliferation and migration of HUVECs were also greater in the presence of formonectin than VEGF(125). Western blot analysis of scratch-wounded confluent HUVECs showed that formononetin induced the phosphorylation of extracellular signal-regulated kinase (ERK) and slightly inhibited the phosphorylation of p38 mitogen-activated protein kinase (MAPK). The formononetin-mediated sustained activation of Egr-1 was suppressed by the ERK inhibitor PD98059 and the p38 inhibitor SB203580. PD98059 inhibited the formononetin-induced endothelial proliferation and repair in scratch-wounded HUVECs, SB203580 increased the cell proliferation and wound healing. Formononetin accelerate wound closure rate as early as day 3 after surgery and consistently observed until day 10 after in wound animal model. These data suggest that formononetin promotes endothelial repair and wound healing in a process involving the over-expression of Egr-1 transcription factor through the regulation of the ERK1/2 and p38 MAPK pathways.

Efficacy of pharmacopuncture using root bark of Ulmus davidiana Planch in patients with knee osteoarthritis: a double-blind randomized controlled trial.

The aim of this study was to determine whether pharmacopuncture is a clinically effective and safe method for the treatment of knee osteoarthritis. Patients were recruited between August 2008 and December 2008 at the Ilsan Hospital associated with Dongguk University. Patients were randomly assigned to one of the two groups. The experimental group (n = 30) received pharmacopuncture using root bark of Ulmus davidiana Planch (UDP) twice a week for 6 weeks; the control group (n = 30) received normal saline injections. Fifty-three patients completed the trial. After the seventh treatment, we found that UDP pharmacopuncture was more effective in pain improvement using a Visual Analog Scale than was normal saline injection. However, the two interventions were not significantly different as measured by the Western Ontario and McMaster Universities pain score and total pain scores, 36-Item Short Form Health Survey, and Korean Health Assessment Questionnaire. No subject showed any serious adverse effects. The effects of pharmacopuncture treatment were a combination of placebo, needle stimulation, mechanical effect of the solution, and a chemical effect of UDP. However, normal saline used as the control intervention displayed the first three effects, and thus its effect was not inert. This may have influenced the results of the trial, which was statistically insignificant between the two groups, except following the seventh treatment session.

Substance P and beta endorphin mediate electroacupuncture induced analgesic activity in mouse cancer pain model.

Cancer pain impairs the quality of life of cancer patients, but opioid analgesics can not only cause inhibition of respiratory function, and constipation, but also other significant side effects such as addiction and tolerance that further decrease quality of life. Thus, in the present study, the effects of electro-acupuncture treatment (EA) on mechanical allodynia were examined in cancer pain mouse model. In order to induce neuropathic cancer pain model, S-180 sarcoma cells were inoculated around the sciatic nerve of left legs of Balb/c mice. The mass of S-180 cancer cells embedded around sciatic nerve in a time course was confirmed by Magnetic Resonance Imaging (MRI) scanning. Mechanical allodynia was most consistently induced in mouse sarcoma cell line S-180 (2 x 10(6) sarcoma cells) treated group among all groups. EA stimulation (2Hz) was daily given to ST36 (Zusanli) of S-180 bearing mice for 30 min for 9 days after S-180 inoculation. EA treatment significantly prolonged paw withdrawal latency from 5 days after inoculation as well as shortened cumulative lifting duration from 7 days after inoculation compared with tumor control. In addition, the overexpressions of pain peptide substance P in dorsal horn of spinal cord were significantly decreased in EA treated group compared with tumor control on Day 9 after inoculation. Furthermore, EA treatment effectively increased the concentration of beta endorphin in blood and brain of mice more than tumor control as well as normal group. The concentration of beta-endorphin for EA treatment group increased by 51.457% in blood 12.6% in brain respectively, compared with tumor control group. These findings suggest that S-180 cancer pain model can be a consistent and short time animal model and also EA treatment can be an alternative therapeutic method for cancer pain via decreased substance P and increased beta endorphin.
