Effectiveness of Acupuncture and Electroacupuncture for Chronic Neck Pain: A Systematic Review and Meta-Analysis

The aim of this systematic review was to assess evidence from randomized controlled trials (RCTs) on the effectiveness and safety of acupuncture and electroacupuncture in patients with chronic neck pain. We searched nine databases including Chinese, Japanese and Korean databases through 30 July 2016. The participants were adults with chronic neck pain and were treated with acupuncture or electroacupuncture. Eligible trials were those with intervention groups receiving acupuncture and electroacupuncture with or without active control, and control groups receiving other conventional treatments such as physical therapy or medication. Outcomes included pain intensity, disability, quality of life (QoL) and adverse effects. For statistical pooling, the standardized mean difference (SMD) and its 95% confidence interval (CI) were calculated using a fixed-effects model. Sixteen RCTs were selected. The comparison of the sole acupuncture group and the active control group did not come out with a significant difference in pain (SMD 0.24, 95% CI [Formula: see text]0.27-0.75), disability (SMD 0.51, 95% CI [Formula: see text]0.01-1.02), or QoL (SMD [Formula: see text]0.37, 95% CI [Formula: see text]1.09-0.35), showing a similar effectiveness of acupuncture with active control. When acupuncture was added into the control group, the acupuncture add-on group showed significantly higher relief of pain in studies with unclear allocation concealment (SMD [Formula: see text]1.78, 95% CI [Formula: see text]2.08-[Formula: see text]1.48), but did not show significant relief of pain in studies with good allocation concealment (SMD [Formula: see text]0.07, 95% CI [Formula: see text]0.26-0.12). Significant relief of pain was observed when the sole electroacupuncture group was compared to the control group or electroacupuncture was added onto the active control group, but a lot of the results were evaluated to have low level of evidence, making it difficult to draw clear conclusions. In the result reporting adverse effects, no serious outcome of adverse event was confirmed. Acupuncture and conventional medicine for chronic neck pain have similar effectiveness on pain and disability when compared solely between the two of them. When acupuncture was added onto conventional treatment it relieved pain better, and electroacupuncture relieved pain even more. It is difficult to draw conclusion because the included studies have a high risk of bias and imprecision. Therefore better designed large-scale studies are needed in the future.

Sipjeondaebo-tang in patients with cancer with anorexia: a protocol for a pilot, randomised, controlled trial.

Introduction Cancer-related anorexia is the loss of appetite or desire to eat in patients with cancer. Although treatments for cancer-related anorexia do exist, patients have sought complementary and alternative medicine including herbal remedies, due to safety concerns. Sipjeondaebo-tang is one among other popular herbal medicines that are beneficial to management of anorexia in Korea. The purpose of this study is to examine the feasibility for a full randomised clinical trial of Sipjeondaebo-tang for cancer-related anorexia. Methods and analysis This study is a randomised, double-blinded and placebo-controlled trial of Sipjeondaebo-tang. For the study, 40 patients with cancer, aged 20–80 years, who reported anorexia, will be recruited. The participants will receive either 3 g of Sipjeondaebo-tang or a placebo, 3 times a day for 4 weeks. The primary end point is a change in the anorexia/cachexia subscale (A/CS) of Functional Assessment of Anorexia/Cachexia Therapy (FAACT). The secondary end points include changes in the visual analogue scale (VAS) of appetite, cortisol and ghrelin. The outcomes will be measured on every visit. Each participant will visit once a week during 4 weeks. Ethics and dissemination The present study has been approved by the Institutional Review Board of the Dunsan Korean Medicine Hospital of Daejeon University (reference DJDSKH-15-03-2 (V.2.0)). The results will be disseminated in a peer-reviewed journal and scientific conference. Trial registration number NCT02468141; Pre-results.

Herbal Medicines for Treating Metabolic Syndrome: A Systematic Review of Randomized Controlled Trials

Objective. The aim of this systematic review is to evaluate the efficacy and safety of herbal medicines in the management of metabolic syndrome. Materials and Methods. On December 9, 2015, we searched PubMed, EMBASE, Cochrane Library, SCOPUS, AMED, CNKI, KoreaMed, KMBASE, OASIS, and J-STAGE with no restriction on language or published year. We selected randomized controlled trials that involved patients with metabolic syndrome being treated with herbal medicines as intervention. The main keywords were “Chinese herbal medicines”, “metabolic syndrome”, and “randomized controlled trials”. Herbal substances which were not based on East Asian medical theory, combination therapy with western medicines, and concurrent diseases other than metabolic syndrome were excluded. The risk of bias was assessed by Cochranes “Risk of Bias” tool. The protocol or review was registered in PROSPERO (an international prospective register of systematic reviews) (CRD42014006842). Results. From 1,098 articles, 12 RCTs were included in this review: five trials studied herbal medicines versus a placebo or no treatment, and seven trials studied herbal medicines versus western medicines. Herbal medicines were effective on decreasing waist circumference, blood glucose, blood lipids, and blood pressure. Conclusion. This study suggests the possibility that herbal medicines can be complementary and alternative medicines for metabolic syndrome.

Comparative Study on the Education System of Traditional Medicine in China, Japan, Korea, and Taiwan

CONTEXT China, Japan, Korea, and Taiwan have developed modernized education systems in traditional medicine. OBJECTIVE This study aims to provide an overview of the education systems in these countries and compare them. METHODS Data were collected through the websites of government agencies, universities, and relevant organizations. RESULTS These countries have systemically developed basic medical education (BME), postgraduate medical education (PGME), and continuing medical education (CME) in traditional medicine. BME is provided at colleges of traditional medicine at the undergraduate level and graduate levels. The length of education at the undergraduate level is five, six, and seven years in China, Korea, and Taiwan, respectively; the length at the graduate level is four years in Korea and five years in Taiwan. A seven- or eight-year program combining undergraduate and graduate courses is unique to China. In Japan, unlike in other countries, there are two distinct education systems-one is comprised of courses on traditional medicine included in the curriculum for Western medical doctors, and the other is a three- or four-year undergraduate program for practitioners including acupuncturists and moxibustionists. PGME in Korea consists of one-year internship and three-year residency programs which are optional; however, in China and Taiwan, internship is required for the national licensing examination and further training is in the process of standardization. The required credits for maintenance of CME are eight per year in Korea, 25 per year in China, and 180 over six years in Taiwan. CONCLUSIONS The design of the educational systems in these countries can provide useful information for the development of education in traditional medicine around the world.

Single-arm, open-label, dose-escalation phase I study to evaluate the safety of a herbal medicine SH003 in patients with solid cancer: a study protocol

Introduction Cancer is a major health problem worldwide and the leading cause of death in many countries. The number of patients with cancer and socioeconomic costs of cancer continues to increase. SH003 is a novel herbal medicine consisting of Astragalus membranaceus, Angelica gigas and Trichosanthes Kirilowii Maximowicz. Preclinical studies have shown that SH003 has therapeutic anticancer effects. The aim of this study is to determine the maximum tolerated dose of SH003 in patients with solid cancers. Methods and analysis This study is an open-label, dose-escalation trial evaluating the safety and tolerability of SH003. The traditional 3+3 dose-escalation design will be implemented. Patients with solid cancers will be recruited. According to dose level, the patients will receive one to four tablets of SH003, three times a day for 3 weeks. Toxicity will be evaluated using common terminology criteria for adverse events (CTCAE). Dose-limiting toxicities are defined as grade 3 or higher adverse events based on CTCAE. The maximum tolerated dose will be determined by the highest dose at which no more than one of six patients experiences dose-limiting toxicity. Ethics and dissemination This study has been approved by the institutional review board of the Ajou University Hospital (reference AJIRB-MED-CT1-16-311). The results of this study will be disseminated through a scientific journal and a conference. Trial registration number NCT03081819; Pre-results.

Abstract 4010: Tonggyu-tang, a traditional Korean medicine, suppresses inflammation, potential implications in tumor microenvironment

The critical roles of inflammation in the development of cancer have long been appreciated. A growing body of evidence supports the notion that infiltrates of inflammatory cells into tumor microenvironment influence the tumor progression by providing bioactive molecules including pro-inflammatory cytokines. Importantly, the increased number of mast cells within tumor microenvironment has been associated with a poor survival in cancer patients. Moreover, keratinocyte inflammation is known to be crucial for skin tumor development. The use of natural products to reduce inflammation in tumor microenvironment is gaining an interest, because of their reduced toxicity toward normal cells. In this study, we tested the effects of Tonggyu-tang (TGT) which is composed of 14 different herbal extracts on the activity of mast cells. We found that TGT significantly reduced the expression and production of inflammatory cytokines such as IL-4, IL-6, IL-8, and TNF-α in PMA and ionomycin- stimulated HMC-1 (human mast cell line-1). In an attempt to determine molecular mechanism underlying the inhibitory effects of TGT on cytokine expression, we revealed that TGT suppressed MAPK signaling pathway including ERK, p38, and JNK as well as NF-κB pathway, which are known to regulate inflammatory cytokine expression. Similar results were obtained from the LPS-stimulated HaCaT cells, immortalized human keratinocytes. Taken together, our results demonstrate that TGT suppresses inflammation by inhibiting the expression of pro-inflammatory cytokine in both mast cells and keratinocytes, thereby potentially leading to inhibition of tumor progression.

Abstract 4310: SH003 induces apoptosis of DU145 prostate cancer cells by inhibiting ERK-involved pathway

Herbal medicines have been used in cancer treatment, with many exhibiting favorable side effect and toxicity profiles compared with conventional chemotherapeutic agents. SH003 is a novel extract from Astragalus membranaceus, Angelica gigas, and Trichosanthes Kirilowii Maximowicz combined at a 1:1:1 ratio that impairs the growth of breast cancer cells. Our data demonstrate that SH003 induced apoptosis in DU145 prostate cancer cells by inhibiting ERK signaling. SH003 induced apoptosis of prostate cancer cells in dose-dependent manner, which was independent of androgen dependency. SH003 also increased intracellular ROS levels but this is not associated with its pro-apoptotic effects. SH003 inhibited phosphorylation of Ras/Raf1/MEK/ERK/p90RSK in androgen-independent DU145 cells, but not androgen-dependent LNCaP and PC-3 cells. Moreover, ERK2 overexpression rescued SH003-induced apoptosis in DU145 cells. Thus, our data conclude that SH003 induces apoptotic cell death of DU145 prostate cancer cells by inhibiting ERK-mediated pathway.

Efficacy and safety of So-Cheong-Ryong-Tang in treatment of perennial allergic rhinitis: study protocol for a double-blind, randomised, parallel-group, multicentre trial

Introduction So-Cheong-Ryong-Tang (SCRT) is a herbal medicine widely used in traditional medicine for treating allergic rhinitis (AR). In animal studies, SCRT has suppressed the progression of AR. The main purpose of this study is to assess the efficacy and safety of the SCRT for the treatment of perennial allergic rhinitis (PAR) and discover the underlying mechanisms resulting in anti-inflammatory effects in humans. Methods and analysis We will conduct a double-blind, randomised, placebo-controlled, parallel-group, multicentre trial of Korean adults with PAR. For the study, 156 subjects with PAR will be recruited. The trial will consist of a 4-week oral administration of SCRT or placebo with two visits at 2-week intervals and an 8-week follow-up period with two visits at 4-week intervals. The primary outcome is a change in the total nasal symptoms score. The secondary outcomes include changes in the Rhinoconjunctivitis Quality of Life Questionnaire score, total serum IgE and cytokines levels.
