Hyeonggaeyeongyo-Tang for Treatment of Allergic and Nonallergic Rhinitis: A Prospective, Nonrandomized, Pre-Post Study
Hyeonggaeyeongyo-tang (HYT) is an ancient formula of oriental medicine traditionally used to treat rhinitis; however, clinical evidence has not yet been established. The aim of this study was to investigate the short-term and long-term efficacy and safety of HYT for chronic rhinitis. Adult subjects with chronic rhinitis symptoms were recruited. The subjects received HYT for 4 weeks and had follow-up period of 8 weeks. Any medicines used to treat nasal symptoms were not permitted during the study. The skin prick test was performed to distinguish the subjects with allergic rhinitis from those with nonallergic rhinitis. After treatment, the total nasal symptoms score and the Rhinoconjunctivitis Quality of Life Questionnaire score significantly improved in the whole subject group, in the allergic rhinitis group, and in the nonallergic rhinitis group, with no adverse events. This improvement lasted during a follow-up period of 8 weeks. Total IgE and eosinophil levels showed no significant difference after treatment in the allergic rhinitis group. HYT improved nasal symptoms and quality of life in patients with allergic rhinitis and nonallergic rhinitis. This is the first clinical study to evaluate the use of HYT to treat patients with rhinitis. This trial has been registered with the ClinicalTrials.gov Identifier NCT02477293
Effect of thread embedding acupuncture for facial wrinkles and laxity: a single-arm, prospective, open-label study
Background: There is a growing trend for patients to seek the least invasive treatments with less risk of complications and downtime for facial rejuvenation. Thread embedding acupuncture has become popular as a minimally invasive treatment. However, there is little clinical evidence in the literature regarding its effects. Methods: This single-arm, prospective, open-label study recruited participants who were women aged 40â59 years, with Glogau photoaging scale IIIâIV. Fourteen participants received thread embedding acupuncture one time and were measured before and after 1 week from the procedure. The primary outcome was a jowl to subnasale vertical distance. The secondary outcomes were facial wrinkle distances, global esthetic improvement scale, AlexiadesâArmenakas laxity scale, and patient-oriented self-assessment scale. Results: Fourteen participants underwent thread embedding acupuncture alone, and 12 participants revisited for follow-up outcome measures. For the primary outcome measure, both jowls were elevated in vertical height by 1.87Â mm (left) and 1.43Â mm (right). Distances of both melolabial and nasolabial folds showed significant improvement. In the AlexiadesâArmenakas laxity scale, each evaluator evaluated for four and nine participants by 0.5 grades improved. In the global aesthetic improvement scale, improvement was graded as 1 and 2 in nine and five cases, respectively. The most common adverse events were mild bruising, swelling, and pain. However, adverse events occurred, although mostly minor and of short duration. Conclusion: In this study, thread embedding acupuncture showed clinical potential for facial wrinkles and laxity. However, further large-scale trials with a controlled design and objective measurements are needed. Keywords: polydioxanone, rejuvenation, rhytidoplasty, skin aging, thread embedding acupunctur
Topical Herbal Application in the Management of Atopic Dermatitis: A Review of Animal Studies
Herbs are widely used in the treatment of atopic dermatitis (AD) in Eastern Asian countries, and certain herbs regarded have anti-inflammatory properties that can help with AD. With the goal of developing a topical herbal agent for AD, we conducted a systematic review of in vivo studies of AD-like skin models for screening potential herbs. Searches were conducted from PubMed and EMBASE. After all, 22 studies were included for this review. We judged most of the domains of all studies to be at unclear risk of bias. Among 22 included studies, 21 herbs have been reported to reduce AD-like skin lesions in mouse models by suppressing Th2 cell response. Our findings may offer potential herbs for the topical application treatment of AD
Effectiveness and safety of combination treatment of herbal medicines and oral antihistamines for atopic dermatitis: a retrospective chart review
Background: Patients with atopic dermatitis (AD) exhibit various symptoms, especially itching. Recently, herbal medicines (HMs) are being used in combination with antihistamines for the treatment of AD in Korea. While oral antihistamines can alleviate itching, HMs appear to exert anti-inflammatory effects with minimal side effects. However, there is little evidence regarding the effectiveness and safety of using HMs in combination with antihistamines for AD.
Methods: To observe the effectiveness and safety of combination treatment with HMs and antihistamines, we performed a retrospective chart review of inpatients with AD who received this combination treatment for at least 7 days in a hospital.
Results: Of 163 inpatients, 40 met the inclusion criteria. All patients received HMs three times, and one or two antihistamines, a day after HM intake. A large proportion of patients received first-generation antihistamines. HMs comprised a mixture of an average of 20.69 different herbs in decoction. The mean total, objective, and subjective SCORing Atopic Dermatitis scores showed a significant decrease after combination treatment. Changes in the mean levels of aspartate transaminase, alanine transaminase, blood urea nitrogen, and creatinine were not statistically significant among treatments. There were no adverse events of pseudoaldosteronism or interstitial pneumonia.
Conclusion: We observed that the short-term use of HMs in combination with oral antihistamines was safe and effective, with a low risk of adverse reactions. This study was limited by its retrospective design, and prospective studies with long-term follow-up periods are warranted to further elucidate the safety of this combination treatment for AD
Autonomic Conditions in Tinnitus and Implications for Korean Medicine
Tinnitus patients suffer from not only auditory sensations but also physical, mental, and social difficulties. Even though tinnitus is believed to be associated with the autonomic nervous system, changes in autonomic conditions in tinnitus patients are not receiving much research attention. The aims of this study were to investigate the autonomic condition of tinnitus patients and to consider Korean medicine in the treatment of tinnitus with an evidence-based approach. We performed a retrospective chart review and compared the heart rate variability (HRV) parameters of 40 tinnitus patients (19 acute and 21 chronic) and 40 healthy controls. In tinnitus patients, the power of the high frequency component and total power of the HRV significantly decreased (P<0.05), and the low frequency to high frequency ratio significantly increased (P<0.05). There was no significant difference between the acute and chronic patients. When comparing each group with the controls, there was a tendency that the longer the duration of tinnitus was, the larger the observed HRV change was. In conclusion, tinnitus patients have vagal withdrawal and sympathetic overactivity, and chronic tinnitus more strongly affects autonomic conditions than acute tinnitus. This study provides evidence for Korean medical treatments of tinnitus, such as acupuncture and Qi-training, that cause modulation of cardiac autonomic function
Effect of Facial Cosmetic Acupuncture on Facial Elasticity: An Open-Label, Single-Arm Pilot Study
Background. The use of acupuncture for cosmetic purposes has gained popularity worldwide. Facial cosmetic acupuncture (FCA) is applied to the head, face, and neck. However, little evidence supports the efficacy and safety of FCA. We hypothesized that FCA affects facial elasticity by restoring resting mimetic muscle tone through the insertion of needles into the muscles of the head, face, and neck. Methods. This open-label, single-arm pilot study was implemented at Kyung Hee University Hospital at Gangdong from August through September 2011. Participants were women aged 40 to 59 years with a Glogau photoaging scale III. Participants received five treatment sessions over three weeks. Participants were measured before and after FCA. The primary outcome was the Moire topography criteria. The secondary outcome was a patient-oriented self-assessment scale of facial elasticity.
Results. Among 50 women screened, 28 were eligible and 27 completed the five FCA treatment sessions. A significant improvement after FCA treatment was evident according to mean change in Moire topography criteria (from 1.70 ± 0.724 to 2.26 ± 1.059, P<0.0001). The most common adverse event was mild bruising at the needle site. Conclusions. In this pilot study, FCA showed promising results as a therapy for facial elasticity. However, further large-scale trials with a controlled design and objective measurements are needed
Millipede-inspired structural design principle for high performance polysaccharide binders in silicon anodes
We systematically investigate polysaccharide binders for high-capacity silicon anodes in lithium ion batteries to find critical factors for the binder function. Analogous to the millipede's strong adhesion based on adhesive pads located on each leg, xanthan gum exhibits the best performance by utilizing its double helical superstructure with side chains and ion-dipole interactions, revealing the great importance of the superstructure and charge interactions in the Si binder design.
Hyperbranched β-Cyclodextrin Polymer as an Effective Multidimensional Binder for Silicon Anodes in Lithium Rechargeable Batteries
Polymeric binders play an important role in electrochemical performance of high-capacity silicon (Si) anodes that usually suffer from severe capacity fading due to unparalleled volume change of Si during cycling. In an effort to find efficient polymeric binders that could mitigate such capacity fading, herein, we introduce polymerized beta-cyclodextrin (beta-CDp) binder for Si nanoparticle anodes. Unlike one-dimensional binders, hyperbranched network structure of beta-CDp presents multidimensional hydrogen-bonding interactions with Si particles and therefore offers robust contacts between both components. Even the Si nanoparticles that lost the original contacts with the binder during cycling recover within multidimensional binder network, thus creating a self-healing effect. Utilizing these advantageous features, beta-CDp-based Si electrode shows markedly improved cycling performance compared to those of other well-known binder cases, especially when combined with linear polymers at an appropriate ratio to form hybrid binders.
Large area multi-stacked lithium-ion batteries for flexible and rollable applications
The demand for lithium ion batteries (LIBs) in various flexible mobile electronic devices is continuously increasing. With this in mind, a vast number of smart approaches, such as implementation of conductive nanomaterials onto paper and textiles, have been recently demonstrated. Most of them were, however, limited to the single-cell level. In the present study, large area flexible battery modules were developed in an attempt to expand the knowledge and design accumulated from the single-cell level approaches to larger-scale applications. A multi-stacked configuration was adopted to produce a high areal energy density in each single-cell. Meanwhile textile-based electrodes on both sides grant mechanical stability, even on the module level, by efficiently releasing the stress generated during aggressive folding and rolling motions. Moreover, the connection between and stacking of the single-cells allow the wide tuning of the overall voltage and capacity of the module. This battery design should be immediately applicable to a broad range of outdoor, building, and military items.
Topical application of Jaungo in atopic dermatitis patients: study protocol for a randomized, controlled trial
Abstract Background Atopic dermatitis (AD) is a common pruritic inflammatory skin disease with increasing prevalence. It can manifest with many different clinical phenotypes; however, in its chronic stage, hyperpigmentation, excoriation, lichenification, and dryness are the main symptoms. Jaungo comprises two herbs, Lithospermi radix and Angelica gigantis radix, and three carrier oils, and is an approved herbal ointment for xerosis cutis in Korea. In past studies, we demonstrated that Jaungo had anti-inflammatory and antiallergic activity in in vitro and in vivo AD models; however, there are few relevant randomized controlled clinical trials on Jaungo in AD. Methods/design A randomized, double-blind, placebo-controlled, single-center, phase IIa clinical trial was designed to investigate the safety, preliminary efficacy, and dose response of Jaungo in AD. The study protocol was approved by the Institutional Review Boards of the Kyung Hee University Korean Medicine Hospital (No. KOMCIRB-160617-HR-027) and the Korea Food and Drug Administration (No. 30907). The study aims to enroll 34 AD patients to be randomly distributed among three parallel groups: treatment 1, treatment 2, and the placebo group. Treatment group 1 applies Jaungo twice a day, while treatment group 2 applies Jaungo and the placebo ointment once a day, separately, and the placebo group applies the placebo ointment twice a day, for a total of 3 weeks each. Participants will be evaluated for eczema before and after the application of the ointments based on several parameters including the Eczema Area and Severity Index, the SCORing of Atopic Dermatitis Index, the Dermatology Life Quality Index, transepidermal water loss, total IgE level, eosinophil count, and IL-17, IL-22, and IFN-γ levels. Discussion The trial is currently ongoing and the enrollment of subjects has been initiated. There is an urgent need to develop a drug for the treatment of dry, hyperpigmented, scaly, and thickened skin in chronic-stage AD. This study will determine the efficacy and safety of Jaungo in AD, providing evidence for specific AD symptoms treated by Jaungo. Trial registration Clinical Trials.gov, identifier: NCT02900131 .
