RESUMO
BACKGROUND: Functional dyspepsia (FD) is a common functional gastrointestinal disorder characterized by recurrent dyspeptic symptoms. Yukgunja-tang (YGT) is a traditional herbal formula that has been used for treating FD. This systematic review protocol aims to provide a guideline for investigating the efficacy and safety of YGT in the treatment of FD. METHODS: The following databases will be searched from their inception until July 2018: Medline (via PubMed), EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Allied and Complementary Medicine Database (AMED), KoreaMed, National Digital Science Library (NDSL), Korean Medical Database (KMbase), Oriental Medicine Advanced Searching Integrated System (OASIS), Korean Studies information Service System (KISS), China National Knowledge Infrastructure Database (CNKI), and Citation Information by Nii (CiNii). Randomized controlled trials (RCTs) that used YGT or modified YGT for treating FD will be included. The control groups in these RCTs will include placebo, no-treatment waiting, and conventional western medicine groups. Trials testing YGT as an adjunct to western medicine for synergistic effect will also be included. The main outcome will be the total clinical efficacy rate. Data extraction and risk of bias assessment will be performed by two independent assessors. RevMan V.5.3 will be used for data analysis. RESULTS: This study will provide a high-quality synthesis of current evidence of YGT for FD from several aspects including dyspepsia-related symptoms, quality of life and adverse events. CONCLUSION: The conclusion of our systematic review will provide evidence to judge whether YGT is an effective intervention for patient with FD. ETHICS AND DISSEMINATION: The protocol does not need ethics approval because identifying information of the participants will not be revealed. The systematic review will be published in a peer-reviewed journal and disseminated electronically and in print. TRIAL REGISTRATION NUMBER: PROSPERO CRD42018090139.

INTRODUCTION: Functional dyspepsia (FD) is a functional gastrointestinal disorder characterized by persistent upper dyspeptic symptoms without organic lesions. There is no standard therapy for FD. Yukgunja-tang (YGJT) is an herbal medicine used for treating upper gastrointestinal symptoms in Asia. Studies on the effect of YGJT on FD have been conducted. However, the results were inconsistent. In Hyungsang medicine, traditional Korean medicine, FD patients are classified into bladder body (BB) or gallbladder body (GB) subtypes by the shape and angle of their faces. Each subtype may have different characteristics, physiology, and pathology of the same disease. YGJT is more effective for patients with BB subtype. The three-dimensional facial shape diagnostic system (3-FSDS) was shown to be effective in diagnosing BB or GB subtypes. This study aimed to investigate the effect of YGJT on FD patients classified using the 3-FSDS. MATERIALS AND METHODS: The current study was a placebo-controlled, double-blinded, randomized, two-center trial. Eligible patients were diagnosed with either BB or GB FD subtype using the 3-FSDS. Ninety-six participants (48 BB and 48 GB subtypes) were randomly allocated to treatment or control groups in a 2:1 ratio. YGJT or placebo was administered for eight weeks. The primary outcome was assessed using the total dyspepsia symptom scale (TDS), while the secondary outcomes were assessed using the single dyspepsia symptom scale (SDS), proportion of responders, visual analog scale, Nepean dyspepsia index, functional dyspepsia-related quality of life, and spleen qi deficiency questionnaire. RESULTS AND DISCUSSION: The result of TDS showed the superior effect of YGJT on BB over GB subtype. The subgroup analysis of TDS and SDS scores showed the superior effect of YGJT over placebo. Other outcome variables did not show any significant differences between groups. CONCLUSION: YGJT may be considered for FD patients diagnosed with BB subtype using 3-FSDS.
RESUMO
OBJECTIVES: This study explored whether religiosity/spirituality has a protective role against negative caregiving outcomes, in a large multicenter nationwide sample of caregivers of patients with dementia in South Korea. Additionally, this study was the first to examine whether religiosity/spirituality could affect caregiving outcomes according to the various religious affiliations of caregivers. METHODS: The study was conducted on a sample of 476 caregivers of patients with dementia participated in the Clinical Research Center for Dementia of South Korea (CREDOS). We examined the moderating effect of each of the three dimensions of religiosity/spirituality (organizational religious activity, ORA; non-organizational religious activity, NORA; intrinsic religiosity, IR) on the relationship between activities of daily living (ADL) of patients with dementia and caregiving burden and depressive symptoms of caregivers, using a series of hierarchical regression analyses. In addition, these analyses were conducted according to the religious affiliations of the caregivers. RESULTS: ORA, NORA, and IR of religiosity/spirituality alleviated the effect of ADL of patients on caregiving burden. ORA and IR moderated the relationship between ADL of patients and depressive symptoms of caregivers. These moderating effects of religiosity on caregiving outcomes were different according to various religious groups. CONCLUSION: We have identified religiosity/spirituality as a protective factor for caregivers of patients with dementia. The sub-dimensions of religiosity as moderators were different by religious affiliations of caregivers. Further studies are needed to investigate the specific religiosity-related factors which could positively impact the mental health of the caregivers of patients with dementia by religions.

The National Health Insurance Service-Health Examinee Cohort during 2002 to 2013 was used to investigate the associations between periodontal disease (PD) and the following non-communicable diseases (NCDs): hypertension, diabetes mellitus, osteoporosis, cerebral infarction, angina pectoris, myocardial infarction, and obesity.Univariate and multivariate logistic regression analyses adjusting for potential confounders during the follow-up period-including age, sex, household income, insurance status, residence area, health status, and comorbidities-were used to estimated odds ratios (ORs) with 95% confidence intervals (CIs) in order to assess the associations between PD and NCDs.We enrolled 200,026 patients with PD and 154,824 subjects with a healthy oral status. Statistically, significant associations were found between PD and the investigated NCDs except for cerebral and myocardial infarction after adjusting for sociodemographic and comorbidity factors (Pâ<â.05). In particular, obesity (ORâ=â1.30, 95% CIâ=â1.04-1.63, Pâ=â.022), osteoporosis (ORâ=â1.22, 95% CIâ=â1.18-1.27, Pâ<â.001), and angina pectoris (ORâ=â1.22, 95% CIâ=â1.17-1.27, Pâ<â.001) were significantly and positively associated with PD.This longitudinal cohort study has provided evidence that patients with PD are at increased risk of NCDs. Further studies are required to confirm the reliability of this association and elucidate the role of the inflammatory pathway in periodontitis pathogenesis as a triggering and mediating mechanism.

Mitochondria are organelles that are readily susceptible to temperature elevation. We selectively delivered a coumarin-based fluorescent iron oxide nanoparticle, Mito-CIO, to the mitochondria. Upon 740 nm laser irradiation, the intracellular temperature of HeLa cells was elevated by 2.1 °C within 5 min when using Mito-CIO, and the treatment resulted in better hyperthermia and a more elevated cytotoxicity than HeLa cells treated with coumarin iron oxide (CIO), which was missing the mitochondrial targeting unit. We further confirmed these results in a tumor xenograft mouse model. To our knowledge, this is the first report of a near-infrared laser irradiation-induced hyperthermic particle targeted to mitochondria, enhancing the cytotoxicity in cancer cells. Our present work therefore may open a new direction in the development of photothermal therapeutics.

Ellagic acid (EA) is a well- known phytochemical that modulates various cellular processes. It is present in a variety of foods, including grapes, strawberries, and nuts. However, the influence of EA on immunological responses is not well defined. Here, we investigated the effects of EA on the lipopolysaccharide (LPS)-induced bone marrow-derived dendritic cells (BMDCs). EA was not cytotoxic to DCs. EA suppressed LPS-induced expression of costimulatory molecules (CD80 and CD86), but it did not suppress the expression of major histocompatibility complex (MHC) class I and MHC class II in BMDCs. In particular, EA blocked LPS-induced c-Jun N-terminal kinase (JNK) activation. LPS-mediated expression of proinflammatory cytokines (IL-12 and IFN-γ) was diminished by EA. We also confirmed that levels of IL-12 and IFN-γ were not influenced by EA in the presence of a JNK inhibitor. Taken together, these data demonstrate that EA regulates the immune response through the modulation of LPS-induced DC maturation.
