Jia J, Gu SX, Mo X, Liu J, Chen D. An updated systematic review and meta-analysis of efficacy and safety of Chinese herbal medicine for treating atopic dermatitis. J DERMATOL TREAT 2023; 34:2268766. [PMID: 37955143 DOI: 10.1080/09546634.2023.2268766] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Accepted: 10/04/2023] [Indexed: 11/14/2023]
Abstract
BACKGROUND This systematic review evaluated the Chinese herbal medicine (CHM) for treating atopic dermatitis (AD). METHODS PubMed, EMBASE, the Cochrane library, the Wanfang database, and China National Knowledge Infrastructure (CNKI) were searched for relevant randomized controlled trials (RCTs) from inception to December 2021. Overall recovery rate, disease/symptom severity scoring, quality of life (QoL), recurrence rate, and incidence of adverse events (AEs) were evaluated. STATA SE 14.0 software was used for statistical analysis. RESULTS 17 RCTs involving 1624 patients were eligible. CHM was associated with a higher overall recovery rate (risk ratio [RR] = 1.15, 95% confidence interval [CI]: 1.05, 1.26, p = .003) and decreased recurrence rate (odds ratio [OR] = 0.19, 95% CI: 0.07, 0.55, p = .002), both confirmed by sensitivity analyses. CHM could decrease scoring atopic dermatitis index (MD = -0.61, 95% CI: -1.12, -0.11, p = .017), however, sensitivity analysis revealed non-robustness. No significant differences were found between the CHM and the control group in Eczema Area and Severity Index, QoL, and the incidence of AEs. CONCLUSIONS CHM was effective for treating AD as it could improve the overall recovery rate and decrease the recurrence rate. More studies are required to validate the potential of CHM on disease/symptoms severity and QoL.

J Nat Med 2023; 77:352-362. [PMID: 36735163 DOI: 10.1007/s11418-023-01683-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Accepted: 01/24/2023] [Indexed: 02/04/2023]
Abstract
Hochuekkito (HET) is a Kampo prescription, used for the clinical treatment of skin diseases such as atopic dermatitis (AD), in Japan. Oral administration of HET exerts anti-allergic effects in an experimental dermatitis mice model and in patients with atopic dermatitis; however, the mechanism underlying the anti-allergic effects of HET is still unclear. Therefore, we investigated the immunopharmacological properties of the anti-allergic actions of HET using a 2,4,6-trinitrochlorobenzene (TNCB)-induced murine contact hypersensitivity (CHS) model and adoptive cell transfer experiments. Oral administration of HET (1.4 g/kg) exhibited anti-allergic effects in a TNCB-induced CHS model via activation of Tregs; this activation was observed even without antigen sensitization in donor mice. Activation was dependent on the duration of HET administration and required at least 4 days of dosing. In addition, the anti-allergic effects of HET through the activation of Tregs were not antigen specific. Flow cytometry results indicated that the proportion of CD4+CD25+Foxp3+ cells in the splenic lymphocytes increased after oral administration of HET. Therefore, oral administration of HET induced both inducible regulatory T cells (iTregs) and thymus-derived naturally occurring regulatory T cells (nTregs). Ginseng radix and Bupleuri radix were involved in the anti-allergic actions of HET through the induction and/or activation of Tregs; Bupleuri radix participated in the activation of nTregs. In conclusion, our findings suggest that HET exerts the anti-allergic effects through the induction and/or activation of Tregs. These findings elucidate the usefulness of HET as an immunomodulator.

A patient who recovered from post-COVID myalgic encephalomyelitis/chronic fatigue syndrome: a case report. Biopsychosoc Med 2023; 17:8. [PMID: 36855180 PMCID: PMC9971667 DOI: 10.1186/s13030-022-00260-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Accepted: 12/19/2022] [Indexed: 03/02/2023] Open
Abstract
BACKGROUND Some patients infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) complain of persistent fatigue, dyspnea, pain, and cognitive dysfunction. These symptoms are often described as "long COVID". Whether a patient with long COVID might develop myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is of interest, as is the treatment and management of ME/CFS in a post-COVID patient. Here I report a patient, who, after an infection with SARS-CoV-2, developed ME/CFS and recovered after treatment. CASE PRESENTATION The patient was a previously healthy 55-year-old woman who worked as a nurse and became ill with COVID-19 pneumonia. She then presented with severe fatigue, post-exertional malaise, dyspnea, pain, cognitive dysfunction, tachycardia, and exacerbation of fatigue on physical exertion, which persisted for more than 6 months after her recovery from COVID-19 pneumonia. She was bedridden for more than half of each day. The patient was treated from multiple perspectives, which included (1) instructions on eating habits and supplements; (2) cognitive and behavioral modifications for coping with physical, emotional, and cognitive fatigue; (3) instructions on conditioning exercises to improve deconditioning due to fatigue and dyspnea; and (4) pharmacotherapy with amitriptyline and hochuekkito, a Japanese herbal (Kampo) medicine. The patient made a complete recovery after completing the prescribed regimen and was able to return to work as a nurse. CONCLUSIONS To the best of my knowledge, this is the first detailed report on a patient infected with SARS-CoV-2 followed by long COVID with the signs/symptoms of ME/CFS who recovered after treatment. I hope this case report will be helpful to health care practitioners by its presentation of some of the therapeutic options for alleviating disabling signs/symptoms in patients with post-COVID ME/CFS.

Survey of Clinical Practice Patterns of Korean Medicine Doctors for Anorexia in Children: A Preliminary Study for Clinical Practice Guidelines. CHILDREN 2022; 9:children9091409. [PMID: 36138718 PMCID: PMC9497536 DOI: 10.3390/children9091409] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 09/13/2022] [Accepted: 09/15/2022] [Indexed: 11/16/2022]
Abstract
Parents often have concerns regarding anorexia in their children and visiting medical institutions for the intervention of it. This study aimed to investigate the clinical practice patterns of Korean medicine doctors (KMDs) for anorexia in children using a web-based survey. A link to the questionnaire was sent via email to all KMDs that were affiliated with the Association of Korean Medicine. The questionnaire covered items on the sociodemographic characteristics and clinical characteristics related to Korean medicine (KM), such as diagnosis, treatment, awareness, safety, and effectiveness. Of 23,910 KMDs, 384 agreed to participate and complete the questionnaire. Anorexia in children was diagnosed mainly by clinical features (36.4%) and the pattern identification (PI) theory of ‘Qi, Blood, Fluid, Humor, and Organ system diagnoses’ (32.8%). The most frequently used PIs was ‘spleen-stomach qi deficiency’ (38.6%), which was followed by ‘spleen failure in transportation’ (23.3%), ‘stomach yin deficiency’ (15.5%), and ‘liver depression’ (14.2%). Herbal medicine (38.1%) was the primary KM treatment for anorexia, and the names of the most frequently prescribed herbal decoctions were Sogunjung-tang (16.5%), Hyangsayukgunja-tang (15.9%), and Bojungikgi-tang (13.9%). This study provides information on the existing clinical practice patterns of KMDs for anorexia in children. Based on this survey, the clinical practice guidelines will be developed.

Abstract
This is the English version of the Clinical Practice Guidelines for the Management of Atopic Dermatitis 2021. Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. In Japan, from the perspective of evidence-based medicine, the current strategies for the treatment of AD consist of three primary measures: (i) use of topical corticosteroids, tacrolimus ointment, and delgocitinib ointment as the main treatment of the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling, and advice about daily life. In the present revised guidelines, descriptions of three new drugs, namely, dupilumab, delgocitinib, and baricitinib, have been added. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

Abstract
BACKGROUND Anorexia and atopic dermatitis (AD) are highly prevalent diseases, and the herbal medicine Bojungikgi-tang (BJT) has been frequently used for the treatment of both anorexia and AD. However, no study has simultaneously evaluated the effects of BJT for both anorexia and AD. METHODS A prospective, randomized, usual care-controlled, assessor-blinded. parallel, pilot clinical trial has been designed to explore the feasibility, preliminary effectiveness, and safety of BJT for the treatment of anorexic patients with AD. Forty anorexic patients with AD will be randomly assigned (1:1) to BJT or the usual care group. The BJT group will be administered BJT granules twice a day for 8 weeks and followed up for 4 weeks whereas the usual care group will not receive BJT granules. All participants in both groups will be provided with over-the-counter topical corticosteroids as a relief drug. Data will be collected at baseline and at 4, 8, and 12 weeks after randomization. The primary outcome is the score on the anorexia visual analog scale at 8 weeks post-treatment. The secondary outcomes include body weight, body fat percentage, body fat mass, skeletal muscle mass, SCORing of Atopic Dermatitis index, Validated Investigator Global Assessment scale for Atopic Dermatitis, Dermatology Life Quality Index, EuroQoL 5 Dimension 5 Level, deficiency and excess pattern identification questionnaire, total immunoglobulin E, eosinophil count, and frequency and amount of use of topical corticosteroids. Adverse events and laboratory test results will be monitored to assess safety. Fecal samples to check for gut microbiome changes and blood samples to check immune and metabolic markers will be collected before and after taking BJT. DISCUSSION This is the first trial that explores the preliminary effectiveness and safety of BJT for the treatment of anorexic patients with AD. The results of this pilot study will provide the basic evidence for large-scale, confirmatory, multicenter, high-quality clinical trials.

Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic relapsing skin disease characterized by recurring episodes of itchiness with skin erythema and surface damages. Chinese medicine (CM) is widely used for the management of AD in China not only by its own, but also used in combination with conventional therapy (integrated Chinese-Western medicine, ICWM). Although many clinical trials on the effectiveness of ICWM on AD have been conducted, however, up to date, no sound evidence has been established on the clinical effectiveness and safety of ICWM for AD. OBJECTIVES To systematically review the currently available clinical evidence on the clinical effectiveness and safety of ICWM for AD. METHODS Randomised and quasi-randomised controlled trials, which investigated ICWM interventions with at least one control group using the same conventional interventions, no treatment or placebo treatment, were included. Four English (CENTRAL, MEDLINE, EMBASE, AMED) and three Chinese (CNKI, CBM, WanFang Med) databases were searched. Risk of bias was assessed according to the Cochrane's tool. Meta-analysis was performed to pool the data. RESULTS From 1473 entries, 55 studies were included, involving 5953 participants aged between 35 days and 67 years old. Duration of treatment ranged from 1 to 24 weeks. Only 2 studies were judged to have low risk of bias, 3 studies had unclear risk of bias, and the other 50 studies were with high risk of bias. ICWM was found to be superior over WM alone in improving clinical severity of AD (measured by EASI, SCORAD), health-related quality of life (measured by CDLQI, DLQI), long term control of AD (recurrence rate), patients/investigator global score (clinical effectiveness rate), and serum IgE level. Adverse events associated with ICWM were found to be comparable with WM alone. CONCLUSION ICWM seems to produce superior treatment response than WM alone in managing AD without increased risk of adverse events. However, the current available evidence remains too weak to make a conclusive decision.

Abstract
Prurigo lesions in atopic dermatitis are intractable. This single-center, retrospective study examined dupilumab's clinical effects on intractable prurigo. Twenty adult atopic dermatitis patients (12 with prurigo, eight without) were administrated dupilumab. Its effects on itching and disease severity were examined with Numerical Rating Scale-Itch (NRS-I), Eczema Area and Severity Index (EASI), and Investigator Global Assessment (IGA) scores; body surface areas (BSA); and thymus- and activation-regulated chemokine (TARC), total immunoglobulin (Ig)E, and eosinophil levels. NRS-I scores, EASI scores, TARC levels, and total IgE levels before dupilumab treatment were not statistically different between the prurigo and non-prurigo groups. With dupilumab treatment, NRS-I scores, EASI scores, IGA scores, BSA, TARC levels, and total IgE levels were significantly reduced from baseline in both groups at 1-2 months and onward, but skin symptom improvement in the prurigo group was slower than in the non-prurigo group, as evidenced by significantly higher EASI scores, BSA, and TARC levels at several time points during the 12 months of dupilumab treatment. Prurigo patients were slower in EASI-50 achievement and significantly lower in EASI-90 achievement at 12 months than non-prurigo patients. Adherence to dupilumab was not different, but total equivalent amounts of concomitant therapeutic agents (corticosteroids and tacrolimus) used during dupilumab treatment were significantly higher in the prurigo group (median, 56.2 g/week) than in the non-prurigo group (median, 33.7 g/week). There were 2.2 adverse events per patient on average; ocular complaints were most frequent. Dupilumab was effective in treating intractable prurigo, but despite significantly greater concomitant therapeutic agent use, skin symptom improvement was slower in prurigo patients than in non-prurigo patients.

The goal of a treatment regimen for atopic dermatitis is to reach and maintain a state where the patient exhibits mild symptoms or an absence of symptoms, and the patient should not experience disturbance during daily activities. The basis of a treatment regimen for atopic dermatitis is topical therapy, and currently there exist topical corticosteroids, tacrolimus and delgocitinib. Using these, proactive therapy is performed as maintenance therapy after remission induction therapy. However, in cases of moderate to severe atopic dermatitis, topical drugs alone cannot induce remission and systemic therapies such as cyclosporin, ultraviolet therapy, and dupilumab should be used in combination. In particular, dupilumab has many advantages such as high efficacy, relatively few adverse reactions, and ease of use in elderly patients with severe atopic dermatitis. In this review, we present a treatment algorithm for atopic dermatitis that emphasizes the importance of maintaining remission after induction of remission, and summarizes the characteristics of current medication therapy for atopic dermatitis in Japan.

Abstract
OBJECTIVE To summarize the recent evidence of traditional Chinese medicine (TCM) for food allergy and eczema. DATA SOURCES Published literature from PubMed database and abstract conference presentations. STUDY SELECTIONS Studies relevant to TCM for food allergy and eczema were included. RESULTS TCM is the main component of complementary and alternative medicine in the United States. Food Allergy Herbal Formula 2 (FAHF-2) (derived from the classical formula Wu Mei Wan) prevented systemic anaphylaxis in murine models and was found to have safety and preliminary immunomodulatory effects on T cells and basophils. The phase II trial of combined TCM with oral immunotherapy and omalizumab for multiple food allergy is ongoing. Retrospective practice-based evidence study revealed that comprehensive TCM therapy effectively prevented frequent and severe food anaphylaxis triggered by skin contact or protein inhalation. The traditional Japanese herbal medicine Kakkonto suppressed allergic diarrhea and decreased mast cells in intestinal mucosa in a murine model. The active compounds from TCM were found to have potent inhibition of immunoglobulin (Ig) E, mast cell activation, and proinflammatory cytokine or signaling pathway (tumor necrosis factor alpha, interleukin 8, NF-κB) suggesting value for both IgE and non-IgE-mediated food allergy. Triple TCM therapy including ingestion, bath, and cream markedly improved skin lesion, itching, and sleep loss in patients with corticosteroid dependent, recalcitrant, or topical steroid withdrawal. Xiao Feng San and Japanese and Korean formulas were found to have effectiveness in eczema. Furthermore, acupuncture reduced wheal size, skin itching, and basophil activation in atopic dermatitis. Moreover, TCM is generally safe. CONCLUSION TCM has potential as safe and effective therapy for food allergy and eczema. Further research is needed for botanical drug development and to further define the mechanisms of actions. TRIAL REGISTRATION FAHF-2: https://ichgcp.net/clinical-trials-registry/NCT00602160; ethyl acetate and butanol purified FAHF-2: https://clinicaltrials.gov/ct2/show/NCT02879006.

Abstract
Background Hochuekkito extract (HET) has multiple effects through the digestive and immune systems, including for acute viral infection and chronic inflammation. We review basic pharmacological and clinical researches of HET and discuss the effects of HET against the pandemic COVID‐19. Methods We reviewed pharmacological studies from 1996 to 30 April 2020 that used experimental animals orally treated with HET and randomized controlled trials (RCTs) from 2000 to 30 April 2020. Results Altogether, 64 pharmacological studies reported immuno‐stimulatory effects against infection and cancer, immuno‐modulative effects against allergy and some inflammatory diseases, and ameliorating effects against exhaustion and frailty. Nine RCTs showed improvement of pulmonary Mycobacterium avium complex disease on chest X‐ray; improved systemic inflammation, nutrition, and quality of life of patients with chronic obstructive pulmonary disease and a decrease in the number getting common cold and exacerbations; reduction of soluble interleukin‐2 receptor and the serum cortisol concentration of postoperative patients; a reduction of the incidence of inflammatory complications and C‐reactive protein elevation after cerebrovascular disease; a reduction of the volume of steroid and tacrolimus during the treatment of atopic dermatitis; a healing effect for intractable chronic wounds; improvement of the physical status of elderly weak patients; and improvement of the fatigue level of cancer patients. Conclusion CODIV‐19 is characterized by high risk for the aged and people with other disease complications, cytokine hyperactivity in the severe stage, and sequelae in the recovery stage. Considering the immune‐stimulative/modulative effects of HET on inflammatory conditions and against exhaustion and frailty, it may be useful for prevention, treatment, and recovery from COVID‐19.

Abstract
Atopic Dermatitis (AD) is a prolonged reverting skin ailment with characteristically distributed
skin lesions. In the previous decades, researchers had shown a marked interest in AD due to
its increased prevalence in developed countries. Although different strategies including biological
and immune modulators are available for the treatment of AD, each has certain limitations. The
researchers had shown considerable interest in the management of AD with herbal medicines. The
establishment of herbal drugs for AD might eliminate local as well as systemic adverse effects associated
with long term use of corticosteroids and also higher cost of therapy with biological drugs.
The present review discusses the traditional East Asian herbal medicines and scientific data related
to newer herbal extracts or compositions for the treatment of AD. In vivo animal models and in
vitro cell cultures, investigated with herbal medicines to establish a possible role in AD treatment,
have also been discussed in the paper. The paper also highlights the role of certain new approaches,
i.e. pharmacopuncture, a combination of allopathic and herbal medicines; and novel carriers
(liposomes, cubosomes) for herbal drugs on atopic skin. In conclusion, herbal medicines can be a
better and safe, complementary and alternative treatment option for AD.

Abstract
Atopic dermatitis (AD) is a common relapsing inflammatory skin disease characterized by severe pruritus that seriously affects the quality of patients' life. There is an increasingly large amount of research demonstrating that traditional Chinese medicine (TCM) including herbal formulae and bioactive ingredients exerts pharmacological effects on atopic dermatitis. It has been a long history of TCM being used to treat atopic dermatitis, especially in preventing disease recurrence, maintaining long-term remission, and reducing disease burden. Nowadays, both of TCM monomer preparations and traditional formulae are still widely used. This review focuses on TCM as well as its bioactive ingredients for the treatment of AD, from the perspectives of animal model construction, pharmacodynamic mechanisms and clinical studies of formulae. To be more specific, the regulation and molecular mechanisms of the herbal formulae and bioactive ingredients of TCM are investigated, and the latest clinical research on TCM formulae is discussed. Furthermore, it provides a summary of the strengths and utilities of TCM, and will be useful for doctors who use Chinese medicine for treatment or researchers who select candidates for clinical treatments or further high-quality clinical studies.

Abstract
Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. The current strategies to treat AD in Japan from the perspective of evidence-based medicine consist of three primary measures: (i) the use of topical corticosteroids and tacrolimus ointment as the main treatment for the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling and advice about daily life. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

Abstract
Hochu-ekki-to (HET) is a traditional Japanese herbal (Kampo) medicine for the treatment of severe weakness, loss of appetite, and indigestion in elderly patients and for the prevention of opportunistic infections. The impact of HET on patients with chronic wounds refractory to conventional therapies was investigated in a prospective, randomized trial, including 18 patients divided into medication (7.5 g oral HET per day, n = 9) and control (n = 9) groups. Wound healing during the 12-week study period was scored based on depth, exudate, size, inflammation/infection, granulation tissue, necrotic tissue, and pocket size. At 12 weeks, wound healing progressed in all nine patients in the medication group, whereas wound healing progressed in only three patients in the control group (significant difference, p < 0.01; relative risk: 3.00). In the medication group, the total score decreased significantly at 8 weeks and later. To the best of our knowledge, this study was the first to show that HET promoted the healing of chronic wounds resistant to conventional treatments. HET may be a choice as an adjunctive therapy for chronic wounds, particularly for patients with malnutrition. This trial was registered with the University Hospital Medical Information Network Clinical Trials Registry (UMIN000031620).

Abstract
BACKGROUND A combination of parts of Cornus officinalis, Rosa multiflora, Lespedeza bicolor, Platycladus orientalis, and Castanea crenata is commonly used for alleviating inflammatory skin disorders. Therefore, this study was carried out to evaluate the in vitro and in vivo preventive effects of a novel herbal formula made from the five plants (C2RLP) against atopic dermatitis in BALB/C mice. METHODS Mice were allocated into five groups (n = 8) including, control (Normal, petrolatum, and betamethasone treated) and treatment groups (treated with 2.5 and 5% C2RLP ointment). Atopic lesion was induced by applying 1-Chloro-2, 4-dinitrobenzene to the dorsal thoracic area of mice. Macroscopical and histological evaluations were performed to determine the effects of treatment on the progress of the skin lesions. The effects of treatment on the production and release of interleukins, interferon -ϒ, nitrite, prostaglandin E2, thymus and activation-receptor chemokine, and β-hexosaminidase were evaluated and comparisons were made between groups. In addition, the chemical compounds present in C2RLP were identified by Liquid Chromatography-Mass Spectrometry. RESULTS Topical application of C2RLP reduced the dermatitis score and suppressed histopathological changes in mice. Treatment significantly reduced (P < 0.05) plasma IL-4 level, the production of nitrite, prostaglandin E2, and thymus and activation-receptor chemokine production. The lipopolysaccharide-induced iNOS-mRNA expression in RAW 264.7 cells was also suppressed by high concentrations of C2RLP. In addition, C2RLP showed an inhibitory effect against DPPH free radical (IC50 = 147.5 μg/ml) and β-hexosaminidase release (IC50 = 179.5 μg/ml). Liquid Chromatography-Mass Spectrometry analysis revealed the presence of various compounds, including loganin, ellagic acid, and kaempferol 3-glucoside. CONCLUSION Down-regulation of T- helper 2 cellular responses and suppression of inflammatory mediators contributed to the protective effects of C2RLP from atopic dermatitis in BALB/C mice.

Abstract
Background Saururus chinensis leaves have been used as traditional medicine in Korea for pain, intoxication, edema, and furuncle. According to previous reports, these leaves exert renoprotective, neuroprotective, and antioxidant effects by attenuating inflammatory responses. However, the beneficial effect of Saururus chinensis leaves on arthritis has not been elucidated. Thus, we evaluated the water extract of Saururus chinensis leaves (SHW) using type II collagen-induced arthritis (CIA) mice models. Methods Quantitative analysis of major components from SHW was performed by HPLC. Arthritis was induced by injection of type II collagen. Each group was orally administered SHW (100 mg/kg and 500 mg/kg). Methotrexate (MTX) was used as a positive control. Serum levels of interleukin-6, TNF-alpha, and type II collagen IgG in the animal models were measured using ELISA. Histological features were observed by H&E staining. Results Quantitative analysis of SHW showed the contents as 56.4 ± 0.52 mg/g of miquelianin, 7.75 ± 0.08 mg/g of quercetin 3-O-(2”-O-β -glucopyranosyl)-α-rhamnopyranoside, and 3.17 ± 0.02 mg/g of quercitrin. Treatment with 500 mg/kg SHW decreased the serum level of Interleukin-6 (IL-6), TNF-alpha, and collagen IgG in the CIA model. Moreover, SHW treatment diminished the swelling of hind limbs and monocyte infiltration in blood vessels in CIA animal models. The results indicate that SHW could decrease CIA-induced arthritis in vivo. Conclusions The results indicate that SHW could be used to improving arthritis by reducing inflammatory factors (IL-6 and TNF-alpha). However, further experiments are required to determine how SHW influences signal transduction in animal models.

[PMID: 30713571 PMCID: PMC6332975 DOI: 10.1155/2019/3637453] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/01/2018] [Revised: 11/05/2018] [Accepted: 11/28/2018] [Indexed: 11/23/2022]
Abstract
The dry rhizome of Acorus gramineus Solander, known as Acori Graminei Rhizoma, is used to treat dementia, stroke, eczema, and indigestion in traditional Chinese medicine, traditional Korean medicine, and traditional Japanese Kampo medicine. Previous studies have reported that Acori Graminei Rhizoma extract ameliorated cognitive impairment in Aβ1-42 injected mice. However, the effect of Acori Graminei Rhizoma on type II collagen induced arthritis (CIA) has not been elucidated. Thus, we evaluated the water extract of Acori Graminei Rhizoma (WAG) in CIA mice models. Male DBA/1 mice were separated into five groups (NOR; n=10, CON; n=10, CIA + methotrexate (MTX); n=10, CIA + 100 mg/kg WAG; n=10, CIA + 500 mg/kg WAG; n=10). CIA was induced by injecting the mice with bovine type II collagen, after which the mice were treated with WAG and/or MTX. Hematological parameters and liver and kidney serum toxicity markers were analyzed. Further, serum levels of interleukin (IL)-6, TNF-α, and type II collagen IgG were analyzed via enzyme-linked immunosorbent assay (ELISA). Treatment with 500 mg/kg WAG decreased serum levels of IL-6, TNF-α, and collagen IgG in a CIA model. Moreover, WAG treatment decreased CIA-induced swelling of mouse hind legs, infiltration of inflammatory cells into the synovial membrane, and blood neutrophil levels. WAG administration did not influence hematological parameters or kidneys and liver toxicity markers. WAG may be used to treat arthritis by reducing the inflammation indicators. However, further experiments are required to determine how WAG affects inflammation mechanisms in vitro and in vivo.

Seven Japanese Herbals Prolonged Cardiac Allograft Survival. Transplant Proc 2018; 50:2789-2793. [PMID: 30401398 DOI: 10.1016/j.transproceed.2018.04.015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2017] [Revised: 03/16/2018] [Accepted: 04/06/2018] [Indexed: 01/24/2023]
Abstract
Japanese herbal medicines have long been used as alternative therapy because of their immunomodulatory effects. In recent years, use herbal medicines is rapidly increasing worldwide. In this study, we investigated the effect of 17 components of traditional Japanese herbal medicines on alloimmune responses in a murine model of cardiac allograft transplantation. Fully vascularized heterotopic hearts from C57BL/6 donors were transplanted into CBA mice by using microsurgical techniques. Artemisiae capillaris herba (Inchinko) was given to CBA recipients at a dosage of 1 g/kg/day from the day of transplantation until 7 days afterward. The other 16 components were given at a dosage of 2 g/kg/day for the same time period. Naïve CBA mice rejected C57BL/6 cardiac grafts acutely (median survival time [MST] of 7 days). CBA transplant recipients given 2 g/kg/day of Glycyrrhizae radix (Kanzou), Poria sclerotium (Bukuryo), Pinellia tuber (Hange), Cnidii rhizome (Senkyu), Paeoniae radix (Shakuyaku), and Scutellariae radix (Ogon) had prolonged C57BL/6 allograft survival significantly (MSTs were 18, 18, 17, 14, 12, and 12 days, respectively). Moreover, CBA transplant recipients given 1g/kg/day of Artemisiae capillaris herba had prolonged C57BL/6 allograft survival (MST >100 days); however, none of other 10 components prolonged allograft survival. In conclusion, administration of 7 components of traditional Japanese herbal medicines might induce prolongation of fully major histocompatibility complex-mismatched cardiac allografts.

Abstract
Rikkunshito (TJ-43), an eight-component traditional Japanese herbal medicine, has been used in clinics for gastritis, vomiting, and appetite loss. We investigated the effects of TJ-43 on the amelioration of appetite loss in the surgical-exposed model of murine cardiac allograft transplantation. CBA mice underwent transplantation of a CBA (syngeneic group) or C57BL/6 heart (allogeneic group) and received oral administration of 2 g/kg/d of TJ-43 from the day of transplantation until 7 days afterward. The amount of food intake (FI) and weight change after operation were recorded from 1 to 28 postoperative days. The allogeneic group had less average amounts of FI for 1 week compared with the syngeneic group (FI was 1.90 ± 0.43 g and 2.66 ± 0.46 g, respectively). Average FIs between the syngeneic and allogeneic groups with TJ-43 for 1 week were 2.36 ± 0.44 g and 2.30 ± 0.13 g, respectively, and those with distilled water were 2.66 ± 0.46 g and 1.90 ± 0.43 g, respectively, suggesting that exposure with TJ-43 tended to ameliorate the reduction of FI. Similarly, the effect on the amelioration of average FI in syngeneic and allogeneic groups exposed for 2 weeks was confirmed. However, exposure to with TJ-43 had no effects on FI after 4 weeks. TJ-43 could prevent reduction of average FI induced by the surgical-exposed model of murine cardiac allograft transplantation.

Abstract
Shigyakusan (also known as Tsumura Japan [TJ]-35) is composed of peony, bitter orange, licorice, and Bupleuri radix is used for cholecystitis and gastritis as an anti-inflammatory agent. We investigated the effect of TJ-35 on alloimmune response in a murine heart transplantation model. CBA mice that underwent transplantation of a C57BL/6 (B6) heart were assigned to four groups: no treatment, TJ-35-exposed, each component-exposed, or each component missing-exposed. The four groups above each received oral administration of TJ-35, each component, or TJ-35 with each component missing from the day of transplantation until 7 days, respectively. Untreated CBA recipients rejected B6 cardiac grafts acutely (median survival time [MST], 7 days). TJ-35-exposed CBA recipients had significantly prolonged B6 allograft survival (MST, 20.5 days). However, MSTs of CBA recipients that had been administered each component and TJ-35 with each component missing did not reach that of TJ-35-exposed recipients. Adoptive transfer of CD4+ splenocytes from TJ-35-exposed primary allograft recipients resulted in significant prolonged allograft survival in naïve secondary recipients (MST, 63 days). Flow cytometry studies showed that the percentage of CD4+CD25+Foxp3+ cell population was increased in TJ-35-exposed CBA recipients. In conclusion, TJ-35-induced prolongation of fully allogeneic cardiac allografts and may generate regulatory CD4+CD25+Foxp3+ cells in our model. The effect seemed to require all components of TJ-35.

Abstract
Background Herbal formula Modified Buzhong-Yiqi-Tang (MBYT) has been widely used for the treatment of functional constipation in East Asia, but its efficacy and safety are unclear. Methods The study was to evaluate the efficacy and safety of MBYT for adult patients with functional constipation. Randomized clinical trials were selected according to predefined inclusion and exclusion criteria. Results In total, twenty-five randomized controlled clinical trials were included with 2089 patients. There was evidence that MBYT treatment significantly improved the symptoms of functional constipation compared with stimulant laxatives, osmotic laxatives, and prokinetic agents. Our results also demonstrated that, when used as an adjuvant therapy, MBYT significantly improved the symptoms of functional constipation, when compared with osmotic laxatives alone, prokinetic agents alone, and biofeedback alone. Moreover, patients taking MBYT experienced fewer adverse events compared to the control groups. Conclusion This review suggests that MBYT appears to have excellent therapeutic effect on adult patients with functional constipation and no serious side effects were identified. However, due to overall limited quality, the therapeutic benefit of MBYT may be substantiated to a limited degree. Better methodological quality and large controlled trials are expected to further quantify the therapeutic effect of MBYT.

Abstract
BACKGROUND Atopic dermatitis (AD) has become a common skin disease that requires systematic and comprehensive treatment to achieve adequate clinical control. Traditional Chinese medicines and related treatments have shown clinical effects for AD in many studies. But the systematic reviews and meta-analyses for them are lacking. OBJECTIVE The systematic review and meta-analysis based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement were conducted to evaluate the efficacy and safety of traditional Chinese medicines and related treatments for AD treatment. METHODS Randomized controlled trials (RCTs) were searched based on standardized searching rules in eight medical databases from the inception up to December 2016 and a total of 24 articles with 1,618 patients were enrolled in this meta-analysis. RESULTS The results revealed that traditional Chinese medicines and related treatments did not show statistical differences in clinical effectiveness, SCORAD amelioration, and SSRI amelioration for AD treatment compared with control group. However, EASI amelioration of traditional Chinese medicines and related treatments for AD was superior to control group. CONCLUSION We need to make conclusion cautiously for the efficacy and safety of traditional Chinese medicine and related treatment on AD therapy. More standard, multicenter, double-blind randomized controlled trials (RCTs) of traditional Chinese medicine and related treatment for AD were required to be conducted for more clinical evidences providing in the future.

Abstract
BACKGROUND Currently, there are no efficient medications available for the prevention and treatment of food allergy (FA). Herbal medicines, including traditional Japanese Kampo medicines (TJKMs), are promising therapeutic drugs. METHODS We screened 18 TJKMs for treatment of FA symptoms in a mouse FA model induced by ovalbumin (OVA). BALB/c mice were sensitized intraperitoneally by an OVA/aluminum hydroxide gel mixture followed by 4 booster doses of oral OVA and FA symptom induction by 50 mg of OVA. TJKMs were orally administered for 28 days from the day of sensitization to the day before FA symptom induction. Evaluated FA symptoms included a decrease in body temperature and allergic diarrhea. Allergic sensitization was determined by plasma OVA-specific IgE levels. Cytokine mRNA levels in mesenteric lymph nodes, plasma mouse mast cell protease-1, and the number of mast cells in the small and large intestines were analyzed. Additionally, the therapeutic effect of the TJKM eppikajutsuto (EJT) on mast cell degranulation was determined in active anaphylaxis and passive cutaneous anaphylaxis models. RESULTS EJT effectively prevented FA symptoms. Although OVA-specific IgE levels and the intestinal mast cell numbers were not different between the EJT-treated and untreated FA mice, plasma mMcpt1 and IL-4 levels were lower in EJT-treated FA mice than untreated FA mice. EJT could alleviate symptoms in both active and passive anaphylaxis models. CONCLUSION EJT prevented OVA-induced FA symptoms in a mouse model, suggesting that EJT might exert its therapeutic activity via IL-4 suppression and the inhibition of mucosal mast cell degranulation.

Abstract
Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. Most patients have an atopic predisposition. The definitive diagnosis of AD requires the presence of all three features: (i) pruritus; (ii) typical morphology and distribution of the eczema; and (iii) chronic and chronically relapsing course. The current strategies to treat AD in Japan from the perspective of evidence-based medicine consist of three primary measures: (i) the use of topical corticosteroids and tacrolimus ointment as the main treatment for the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling and advice about daily life. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

Abstract
Given the importance of appropriate diagnosis and appropriate assessment of cutaneous symptoms in treatment of atopic dermatitis, the basics of treatment in this guideline are composed of (1) investigation and countermeasures of causes and exacerbating factors, (2) correction of skin dysfunctions (skin care), and (3) pharmacotherapy, as three mainstays. These are based on the disease concept that atopic dermatitis is an inflammatory cutaneous disease with eczema by atopic diathesis, multi-factorial in onset and aggravation, and accompanied by skin dysfunctions. These three points are equally important and should be appropriately combined in accordance with the symptoms of each patient. In treatment, it is important to transmit the etiological, pathological, physiological, or therapeutic information to the patient to build a favorable partnership with the patient or his/her family so that they may fully understand the treatment. This guideline discusses chiefly the basic therapy in relation to the treatment of this disease. The goal of treatment is to enable patients to lead an uninterrupted social life and to control their cutaneous symptoms so that their quality of life (QOL) may meet a satisfactory level. The basics of treatment discussed in this guideline are based on the "Guidelines for the Treatment of Atopic Dermatitis 2008" prepared by the Health and Labour Sciences Research and the "Guidelines for the Management of Atopic Dermatitis 2015 (ADGL2015)" prepared by the Atopic Dermatitis Guidelines Advisory Committee, Japanese Society of Allergology in principle. The guidelines for the treatment of atopic dermatitis are summarized in the "Japanese Guideline for the Diagnosis and Treatment of Allergic Disease 2016" together with those for other allergic diseases.

Abstract
BACKGROUND Complementary and alternative interventions are becoming increasingly utilized as adjuncts to conventional treatment of atopic dermatitis (AD). While the number of studies continues to grow, the vastness of the subject coupled with the relatively poor quality and small size of the studies limit their usefulness to clinicians. PURPOSE Our aim was to comprehensively review randomized controlled trials (RCTs) of complementary and alternative therapies for AD. METHODS Searches were performed on PubMed, the Cochrane Central Register of Controlled Trials, EMBASE, and the Global Resource for EczemA Trial (GREAT) databases, focusing on RCTs of alternative or complementary AD therapies, with a sample size of ≥10, through March 2015 and limited to the English language. A total of 70 manuscripts met the inclusion criteria and were included in the final analysis. RESULTS There is at least some level I evidence to support the use of acupuncture and acupressure, stress-reducing techniques such as hypnosis, massage, and biofeedback, balneotherapy, herbal preparations (with many important caveats), certain botanical oils, oral evening primrose oil, vitamin D supplementation, and topical vitamin B12. Many other therapies either have sufficient data to suggest that they are ineffective, or simply do not have enough evidence to formulate a verdict. CONCLUSIONS Careful review of the literature reveals several promising therapies in this domain; such findings may help direct further research that is necessary to bolster clinical recommendations for alternative or complementary treatments of AD.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Chinese herb compound prescription Viola yedoensis Makino Anti-itching Compound (VYAC), which consists of Viola yedoensis Makino, herb, Sophora flavescens Aiton, root, and Dictamnus dasycarpus Turcz, root and rhizome, has been traditionally used to treat various skin allergic inflammatory diseases in clinic. AIM OF THE STUDY The aim of this study is to investigate the effects of VYAC on degranulation and to determine its anti-inflammatory mechanism in RBL-2H3 mast cells. MATERIALS AND METHODS VYAC was extracted with water-coction extraction (Shufen et al., 2012). The aqueous extracts were concentrated in vacuum under reduced pressure and lyophilized using a freeze dryer, and lyophilized powder was obtained. MTT was used to evaluate the cytotoxic of VYAC on RBL-2H3 cells. Degranulation was carried out with RBL-2H3 cell model, which was stimulated with A23187 plus PMA. β-Hexosaminidase and histamine were measured to evaluate degranulation. The mRNA levels of inflammation cytokines (IL-1β, TNF-α, IL-6, and iNOS) were investigated by RT-PCR to explain the anti-inflammatory mechanism of VYAC. RESULTS VYAC did not show cytotoxic effect on RBL-2H3 cells in the range of 25-400μg/mL. A higher dose of VYAC (800μg/mL) showed significant cytotoxicity (P<0.05). VYAC could significantly inhibit β-hexosaminidase and histamine release when treated with 100, 200, and 400μg/mL (P<0.05), but could not significantly inhibit β-Hexosaminidase and histamine release when treated with 25 and 50μg/mL (p>0.05). The mRNA levels of inflammatory cytokines (TNF-α, IL-1β, IL-6, and iNOS) could significantly decrease when treated with 200 and 400μg/mL (P<0.05) of VYAC, which were associated with the development of inflammation. CONCLUSIONS Results showed that VYAC inhibited β-hexosaminidase and histamine release, which was inhibit A23187 plus PMA stimulated RBL-2H3 cell degranulation and downregulated inflammatory cytokines (IL-1β, TNF-α, IL-6, and iNOS) expression to block inflammatory development.

BackgroundEczema is a very common chronic inflammatory skin condition.ObjectivesTo update the National Institute for Health Research (NIHR) Health Technology Assessment (HTA) systematic review of treatments for atopic eczema, published in 2000, and to inform health-care professionals, commissioners and patients about key treatment developments and research gaps.Data sourcesElectronic databases including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Skin Group Specialised Register, Latin American and Caribbean Health Sciences Literature (LILACS), Allied and Complementary Medicine Database (AMED) and Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched from the end of 2000 to 31 August 2013. Retrieved articles were used to identify further randomised controlled trials (RCTs).Review methodsStudies were filtered according to inclusion criteria and agreed by consensus in cases of uncertainty. Abstracts were excluded and non-English-language papers were screened by international colleagues and data were extracted. Only RCTs of treatments for eczema were included, as other forms of evidence are associated with higher risks of bias. Inclusion criteria for studies included availability of data relevant to the therapeutic management of eczema; mention of randomisation; comparison of two or more treatments; and prospective data collection. Participants of all ages were included. Eczema diagnosis was determined by a clinician or according to published diagnostic criteria. The risk of bias was assessed using the Cochrane Collaboration risk-of-bias tool. We used a standardised approach to summarising the data and the assessment of risk of bias and we made a clear distinction between what the studies found and our own interpretation of study findings.ResultsOf 7198 references screened, 287 new trials were identified spanning 92 treatments. Trial reporting was generally poor (randomisation method: 2% high, 36% low, 62% unclear risk of bias; allocation concealment: 3% high, 15% low, 82% unclear risk of bias; blinding of the intervention: 15% high, 28% low, 57% unclear risk of bias). Only 22 (8%) trials were considered to be at low risk of bias for all three criteria. There was reasonable evidence of benefit for the topical medications tacrolimus, pimecrolimus and various corticosteroids (with tacrolimus superior to pimecrolimus and corticosteroids) for both treatment and flare prevention; oral ciclosporin; oral azathioprine; narrow band ultraviolet B (UVB) light; Atopiclair™ and education. There was reasonable evidence to suggest no clinically useful benefit for twice-daily compared with once-daily topical corticosteroids; corticosteroids containing antibiotics for non-infected eczema; probiotics; evening primrose and borage oil; ion-exchange water softeners; protease inhibitor SRD441 (Serentis Ltd); furfuryl palmitate in emollient; cipamfylline cream; andMycobacterium vaccaevaccine. Additional research evidence is needed for emollients, bath additives, antibacterials, specialist clothing and complementary and alternative therapies. There was no RCT evidence for topical corticosteroid dilution, impregnated bandages, soap avoidance, bathing frequency or allergy testing.LimitationsThe large scope of the review coupled with the heterogeneity of outcomes precluded formal meta-analyses. Our conclusions are still limited by a profusion of small, poorly reported studies.ConclusionsAlthough the evidence base of RCTs has increased considerably since the last NIHR HTA systematic review, the field is still severely hampered by poor design and reporting problems including failure to register trials and declare primary outcomes, small sample size, short follow-up duration and poor reporting of risk of bias. Key areas for further research identified by the review include the optimum use of emollients, bathing frequency, wash products, allergy testing and antiseptic treatments. Perhaps the greatest benefit identified is the use of twice weekly anti-inflammatory treatment to maintain disease remission. More studies need to be conducted in a primary care setting where most people with eczema are seen in the UK. Future studies need to use the same core set of outcomes that capture patient symptoms, clinical signs, quality of life and the chronic nature of the disease.FundingThe National Institute for Health Research Programme Grants for Applied Research programme.

Abstract
BACKGROUND The Committee for Evidence-based Medicine (EBM) of the Japan Society for Oriental Medicine started compiling Evidence Reports of Kampo Treatment (EKAT) in 2007. EKAT is a compilation of structured abstracts of randomized controlled trials (RCTs), along with comments by a third party reviewer. As of 31 December, 2012, there were 378 RCTs of Kampo medicines in Japan. The primary research question of this study is "How frequently is Kampo diagnosis used in RCTs of Kampo medicines?" The secondary research question is "When is Kampo diagnosis used in RCTs?" MATERIALS AND METHODS The structured abstract (SA) of each RCT article was reviewed to examine how Kampo diagnosis was used in RCTs, especially how Kampo diagnosis was used in the randomization process. RESULTS Kampo diagnosis was used before randomization in 27 RCTs (7.1%), after randomization in 31 RCTs (8.2%), and not used in 320 RCTs (84.7%). Before randomization, Kampo diagnosis was used as a criterion for inclusion in 10 RCTs, criterion for exclusion in 9 RCTs, and criteria for both inclusion and exclusion in 2 RCTs. Kampo formulas were determined according to Kampo diagnosis in 7 RCTs. After randomization, subgroup analyses according to Kampo diagnosis were done in 27 RCTs, and grade of disease severity at Kampo diagnosis was used for analysis as an endpoint in 4 RCTs. CONCLUSIONS Kampo diagnosis was used before randomization only in approximately 15% of RCTs, and the number of RCT articles using Kampo diagnosis after randomization was almost the same as that before randomization. Further studies to determine the good RCTs conforming to CONSORT requirements and good systematic reviews conforming to PRISMA requirements are needed to clarify the significance of Kampo diagnosis.

Abstract
Herbal medicines have been used for over 3,000 years in Asian as alternative therapy for their variety effects and have recently become popular in Europe and the United States. In the last 30 years, Japanese herbal medicines were widely used for treatment of diseases after been recognized officially by Japanese government. In this study, we investigated the effect of 34 kinds of traditional Japanese herbal medicines on alloimmune responses in a murine model of cardiac allograft transplantation. CBA mice (H2(k)) underwent transplantation of a C57BL/6 (H2(b)) heart and received oral administration of 2 g/kg/d of the 34 kinds of herbal medicines from the day of transplantation until 7 days afterward. Naïve CBA mice rejected B6 cardiac grafts acutely (median survival time [MST], 7 days). CBA transplant recipients given 2 g/kg/d of Sairei-to (TJ-114) and Tokishakuyaku-san (TJ-23) had prolonged C57BL/6 allograft survival indefinitely (both MSTs > 100 days). Moreover, CBA transplant recipients given Seisinrensiin (TJ-111), Tokishigyakukagoshuyushokyoto (TJ-38), Rikkunshito (TJ-43), Maobushisaishinto (TJ-127), Ninjin-yoei-to (TJ-108), Ryokan-kyomi-shinge-nin-to (TJ-119), Inchingorei-san (TJ-117), Hochuekkito (TJ-41), Kihi-to (TJ-65), and Sinbu-to (TJ-30) had also prolonged C57BL/6 allograft survival significantly (MSTs of 28, 22, 16, 14, 14, 13, 12, 9.5, 9 and 9 days, respectively). However, none of other 22 kinds of herbal medicines could prolong the allograft survival. Furthermore, oral administration of 2 g/kg/d of Daikenchuto (TJ-100) induced sudden death (within 1 minute) in CBA mice. In conclusion, 12 kinds of Japanese herbal medicines prolonged allograft survival and one showed toxic effect in mice.

Abstract
BACKGROUND Morus alba, a medicinal plant in Asia, has been used traditionally to treat diabetes mellitus and hypoglycemia. However, the effects of M. alba extract (MAE) on atopic dermatitis have not been verified scientifically. We investigated the effects of MAE on atopic dermatitis through in vitro and in vivo experiments. METHODS We evaluated the effects of MAE on the production of nitric oxide (NO) and prostaglandin E2 (PGE2) in RAW 264.7, as well as thymus and activation-regulated chemokine (TARC/CCL17) in HaCaT cells. In an in vivo experiment, atopic dermatitis was induced by topical application of house dust mites for four weeks, and the protective effects of MAE were investigated by measuring the severity of the skin reaction on the back and ears, the plasma levels of immunoglobulin E (IgE) and histamine, and histopathological changes in the skin on the back and ears. RESULTS MAE suppressed the production of NO and PGE2 in RAW 264.7 cells, as well as TARC in HaCaT cells, in a dose-dependent manner. MAE treatment of NC/Nga mice reduced the severity of dermatitis and the plasma levels of IgE and histamine. MAE also reduced the histological manifestations of atopic dermatitis-like skin lesions such as erosion, hyperplasia of the epidermis and dermis, and inflammatory cell infiltration in the skin on the back and ears. CONCLUSION Our results suggest that MAE has potent inhibitory effects on atopic dermatitis-like lesion and may be a beneficial natural resource for the treatment of atopic dermatitis.

Abstract
INTRODUCTION Atopic dermatitis is a chronic, inflammatory skin rash that greatly affects quality of life. The current therapies are inadequate in managing atopic dermatitis and often have associated adverse effects or drug tolerance development. Chinese medicine is expected to have promising prospects in the management of atopic dermatitis and recent studies have shown encouraging results. This study aims to evaluate the efficacy and safety of a newly formulated Chinese herbal formula, RMIT Chinese Medicine-106 (RCM-106), in the management of moderate-to-severe atopic dermatitis in children aged 6-18 years. METHODS The study is a randomised, double-blind, placebo-controlled, parallel-armed clinical trial. Participant, investigator and assessors will remain blinded to the treatment assignment until after the study has been completed. After a 2-week run-in period, 90 participants will be randomised, using block randomised sequences generated by computer, to receive either RCM-106 or matching placebo capsules, twice daily, for a treatment period of 8 weeks and followed up for 4 weeks. Primary outcome measures include the evaluation of disease severity and extent using two validated scoring instruments-Scoring Atopic Dermatitis (SCORAD) and Patient-Oriented Scoring Atopic Dermatitis (PO-SCORAD). Secondary outcome measures include the evaluation of quality of life using the Children's Dermatology Life Quality Index (CDLQI); occurrence of adverse events and total usage of other therapies as recorded in the participants' daily diary and laboratory studies which include eosinophil count, total IgE, full blood count and liver and kidney function tests. Intention-to-treat analysis will be applied to all data analyses. ETHICS AND DISSEMINATION This trial has received human ethics approval from the Human Research Ethics Committee (HREC) of RMIT University (Project number 15/12). The study findings will be published in peer-reviewed journals and presented at the national and international conferences. TRIAL REGISTRATION Australia and New Zealand Clinical Trials Register (ANZCTR): ACTRN12612001181897. TGA CTN Scheme: Trial number 2012/0713; Protocol number 15/12.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin disease with recurring episodes of itching and a chronic relapsing course. Current treatment options for AD include topical agents, such as topical corticosteroids and oral antiallergic drugs. Providing effective long-term treatment is sometimes difficult due to the chronic, relapsing nature of AD; therefore, there is a need to identify better therapeutic options with minimal side effects that are well tolerated over the variable course of the disease. Traditional herbal medicine, also known as Kampo medicine in Japan, has a long history and plays a role in the prevention and treatment of various diseases, including AD. Some Kampo medicines are useful for treating inflammatory skin diseases, and there has been increased interest in using Kampo medicine to develop new therapeutic agents for AD. Standard Kampo formulas for AD are effective in removing the symptoms of “Netsu Sho,” “Ketsu-Kyo,” “Ki-Kyo,” and “O-Ketsu.” This paper discusses the efficacy of Kampo medicines in treating AD. Knowledge of the mechanisms of action of Kampo medicines will result in greater choices of pharmacotherapeutic agents for AD.

Abstract
The roots of Averrhoa carambola L. (Oxalidaceae) have a long history of medical use in traditional Chinese medicine for treating diabetes and diabetic nephropathy. 2-Dodecyl-6-methoxycyclohexa-2,5-diene-1,4-dione (DMDD) was isolated from the tuberous roots of A. carambola L. The purpose of this study was to investigate the beneficial effect of DMDD on the advanced glycation end-product-mediated renal injury in type 2 diabetic KKAy mice with regard to prove its efficacy by local traditional practitioners in the treatment of kidney frailties in diabetics. KKAy mice were orally administrated DMDD (12.5, 25, 50mg/kg body weight/d) or aminoguanidine (200mg/kg body weight/d) for 8 weeks. Hyperglycemia, renal AGE formation, and the expression of related proteins, such as the AGE receptor, nuclear factor-κB, transforming growth factor-β1, and N(ε)-(carboxymethyl)lysine, were markedly decreased by DMDD. Diabetes-dependent alterations in proteinuria, serum creatinine, creatinine clearance, and serum urea-N and glomerular mesangial matrix expansion were attenuated after treatment with DMDD for 8 weeks. The activities of superoxide dismutase and glutathione peroxidase, which are reduced in the kidneys of KKAy mice, were enhanced by DMDD. These findings suggest that DMDD may inhibit the progression of diabetic nephropathy and may be a therapeutic agent for regulating several pharmacological targets to treat or prevent of diabetic nephropathy.

Abstract
A Kampo prescriptions, hochuekkito (HET) has been utilized for treating functional conditions such as general fatigue, compromised state and gastrointestinal motility disorder. Recently, HET has attracted the attention of dermatologists because of its clinically positive effects in atopic dermatitis (AD) treatment. To explain this positive effect of HET, we examined its protective ability against oxidative skin stress using a murine model. The dorsal region of 8-week-old male HR-1 hairless mice, which were raised on a HET (0%, 2% and 10%) mixed diet, was irradiated once with 70 mJ/cm(2) of ultraviolet (UV)-B light. After 4 days, transepidermal water loss (TEWL) and stratum corneum water content (SCWC), were determined as a measure of degree of skin dysfunction. To estimate the amount of active oxygen generated, the stratum corneum catalase activity (SCCA) and stratum corneum carbonylated protein (SCCP) content in the tape-stripped stratum corneum samples were measured. We also measured the H(2) O(2) scavenging ability of HET, and analyzed the changes in the expression levels of several inflammation and oxidative stress-related genes in the skin of HET-fed mice. In control mice, exposure to UV-B led to significant increases in TEWL and SCCP and significant decreases in SCWC and SCCA. These UV-B-induced changes were reduced in mice administrated HET, and the reduction was HET dose-dependent. Our results suggested that HET offered a protective effect against UV-B-induced skin damage. We also found that HET had relatively low ability to scavenge H(2) O(2) , and expression level of cyclooxygenase-2 mRNA decreased in HET-fed mouse.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin disease with recurring episodes of itching and a chronic relapsing course. Keishibukuryogan (KBG) is a traditional herbal medicine, composed of five kinds of medical plants and has been administered to patients with blood stagnation in Japan. This study investigated the effect of KBG on the disease activity in AD (n = 45) patients. AD patients were administered KBG for 4 to 6 weeks in addition to their prescribed medications. The results showed that the SCORAD index and VAS score were significantly decreased after the administration of KBG (P < 0.01). KBG also decreased the serum LDH level significantly (P < 0.01). The global assessment of the clinical response in SCORAD index showed that 88.5% of the patients with moderate improvement to excellent response (n = 26) had a high lichenification score (lichenification score ≥2 in SCORAD). On the other hand, only 42.1% of the patients with no improvement to mild improvement (n = 19) had a high lichenification score. Furthermore, long-term administration of KBG for 9-67 weeks showed a marked improvement in patients with a high lichenification score. Therefore, KBG was found to be effective against AD, particularly in cases presenting with lichenified lesions.

Abstract
AIM Hwang-Yeon-Hae-Dok-San (TJ-15) and Ou-Ryung-San (TJ-17) are two common herbal formulas that have been used to treat atopic dermatitis (AD), especially the Dampness-Heat pattern of AD. The aim of this study was to determine the safety and efficacy of TJ-15 plus TJ-17 for patients with the Dampness-Heat pattern of AD based on pattern identification. METHODS This study was a parallel, randomized, active-controlled, double-blind trial. A total of 24 patients were enrolled. Either a combination of TJ-15 plus TJ-17, or TJ-15 alone was orally administered 3 times daily for 4 weeks. Of the patients enrolled, 19 patients completed the 4-week treatment course (TJ-15 plus TJ-17: n=8, TJ-15: n=11). Efficacy was assessed using the scoring atopic dermatitis (SCORAD) index; area of eczema and severity index (EASI); as well as the symptoms related to the Dampness-Heat by pattern identification. Efficacy measures were evaluated at the baseline and at 4 weeks. Safety was assessed throughout the study using ongoing laboratory tests. RESULTS Both the SCORAD and EASI showed more improvement in the TJ-15 plus TJ-17 group than in the TJ-15 group; however, the differences were not statistically significant. The symptoms related to the Dampness-Heat pattern were reduced in both groups, and the changes were similar. There were no reported adverse events during this study, or abnormalities observed on aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, and creatinine testing. CONCLUSIONS The results of this study suggest that both the TJ-15 plus TJ-17 and the TJ-15 provided safe and effective treatment for patients with the Dampness-Heat pattern type of AD.

Inchingorei-san (TJ-117) and Artemisiae Capillaris Herba Induced Prolonged Survival of Fully Mismatched Cardiac Allografts and Generated Regulatory Cells in Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:689810. [PMID: 22811750 PMCID: PMC3395131 DOI: 10.1155/2012/689810] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/17/2012] [Accepted: 05/21/2012] [Indexed: 11/17/2022]
Abstract
We investigated Inchingorei-san (TJ-117), a 6-component Japanese herbal medicine, on alloimmune responses in murine cardiac allograft transplantation. CBA mice underwent transplantation of a C57BL/6 (B6) heart and received oral administration of TJ-117 or each component of TJ-117 from the day of transplantation until 7 days afterward. Naive CBA mice rejected B6 cardiac grafts acutely (median survival time (MST), 7 days). CBA recipients given 1 g/kg/day of TJ-117 had prolonged B6 allograft survival (MST, 37 days). Moreover, given 1 g/kg/day of Artemisiae Capillaris Herba (ACH), one component of TJ-117, indefinitely prolonged B6 allograft survival (MST, >100 days). However, other five components of TJ-117 were less effective than TJ-117 and ACH. Secondary CBA recipients given whole splenocytes, CD4+, and CD4+CD25+ cells from primary ACH-treated CBA recipients with B6 cardiac allografts 30 days after grafting had prolonged survival of B6 hearts (MSTs, 57, >100, and >100 days, resp.). Flow cytometry studies showed that the CD4+CD25+Foxp3+ regulatory cell population was increased in transplant recipients given ACH. Cell proliferation, interleukin-2, and interferon-γ were suppressed in ACH-treated mice, whereas interleukin-4 and interleukin-10 were upregulated. In conclusion, ACH, one component of TJ-117, as well as TJ-117 induced hyporesponsiveness to fully allogeneic cardiac allografts and may generate CD4+CD25+Foxp3+ regulatory cells.

Inhibitory effect of Psidium guajava water extract in the development of 2,4-dinitrochlorobenzene-induced atopic dermatitis in NC/Nga mice. Food Chem Toxicol 2012; 50:2923-9. [PMID: 22609491 DOI: 10.1016/j.fct.2012.04.044] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2012] [Revised: 04/23/2012] [Accepted: 04/27/2012] [Indexed: 12/22/2022]
Abstract
Atopic dermatitis (AD) is a chronic, relapsing, and inflammatory skin disease associated with eczematous symptoms and IgE hyperproduction. Psidium guajava is an important food crop and medicinal plant with anti-oxidant, anti-inflammatory, and anti-allergic activities, supporting its traditional uses. Our previous studies have shown that P. guajava extract inhibits Th2 chemokine expression by suppressing the activation of NF-κB and STAT1 co-stimulated with TNF-α and INF-γ. In this study, we investigated the inhibitory effect of P. guajava water extract (PGW) on 2,4-dinitrochlorobenzene (DNCB)-induced AD-like skin lesions in NC/Nga mice. Treatment of cream containing PGW onto DNCB-induced AD-like skin lesions in NC/Nga mice ameliorated lesion intensity scores, levels of IgE, thymus and activation-regulated chemokine (TARC), TNF-α, and IL-4 in serum and ears. In contrast, PGW increased level of the immunosuppressive cytokine IL-10. Histological analyses demonstrated decreased thickening of the epidermis/dermis as well as dermal infiltration by inflammatory cells. These results suggest that cream containing PGW may be a potential therapeutic modality for AD and adjunctive agent to control pruritus in AD.

Abstract
Chronic inflammation of the hair follicle (HF) is considered a contributing factor in the pathogenesis of androgenetic alopecia (AGA). Previously, we clinically tested liposterolic extract of Serenoa repens (LSESr) and its glycoside, β-sitosterol, in subjects with AGA and showed a highly positive response to treatment. In this study, we sought to determine whether blockade of inflammation using a composition containing LSESr as well as two anti-inflammatory agents (carnitine and thioctic acid) could alter the expression of molecular markers of inflammation in a well-established in vitro system. Using a well-validated assay representative of HF keratinocytes, specifically, stimulation of cultured human keratinocyte cells in vitro, we measured changes in gene expression of a spectrum of well-known inflammatory markers. Lipopolysaccharide (LPS) provided an inflammatory stimulus. In particular, we found that the composition effectively suppressed LPS-activated gene expression of chemokines, including CCL17, CXCL6 and LTB(4) associated with pathways involved in inflammation and apoptosis. Our data support the hypothesis that the test compound exhibits anti-inflammatory characteristics in a well-established in vitro assay representing HF keratinocyte gene expression. These findings suggest that 5-alpha reductase inhibitors combined with blockade of inflammatory processes could represent a novel two-pronged approach in the treatment of AGA with improved efficacy over current modalities.

Analysis of the Potential Topical Anti-Inflammatory Activity of Averrhoa carambola L. in Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2011; 2011:908059. [PMID: 21785638 PMCID: PMC3137785 DOI: 10.1093/ecam/neq026] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/15/2009] [Accepted: 03/08/2010] [Indexed: 12/29/2022]
Abstract
Inflammatory skin disorders, such as psoriasis and atopic dermatitis, are very common in the population; however, the treatments currently available are not well tolerated and are often ineffective. Averrhoa carambola L. (Oxalidaceae) is an Asian tree that has been used in traditional folk medicine in the treatment of several skin disorders. The present study evaluates the topical anti-inflammatory effects of the crude ethanolic extract of A. carambola leaves, its hexane, ethyl acetate, and butanol fractions and two isolated flavonoids on skin inflammation. Anti-inflammatory activity was measured using a croton oil-induced ear edema model of inflammation in mice. Topically applied ethanolic extract reduced edema in a dose-dependent manner, resulting in a maximum inhibition of 73 ± 3% and an ID50 value of 0.05 (range: 0.02–0.13) mg/ear. Myeloperoxidase (MPO) activity was also inhibited by the extract, resulting in a maximum inhibition of 60 ± 6% (0.6 mg/ear). All of the fractions tested caused inhibition of edema formation and of MPO activity. Treatment with the ethyl acetate fraction was the most effective, resulting in inhibition levels of 75 ± 5 and 54 ± 8% for edema formation and MPO activity, respectively. However, treatment of mice with isolated compounds [apigenin-6-C-β-l-fucopyranoside and apigenin-6-C-(2″-O-α-l-rhamnopyranosyl)-β-l-fucopyranoside] did not yield successful results. Apigenin-6-C-(2″-O-α-l-rhamnopyranosyl)-β-l-fucopyranoside caused only a mild reduction in edema formation (28 ± 11%). Taken together, these preliminary results support the popular use of A. carambola as an anti-inflammatory agent and open up new possibilities for its use in skin disorders.
