These patients confront pain, psychological bother and social/occupational limitations. Being efficient for a wide variety of diseases including infectious inflammative degenerative or tumoral, photodynamic therapy holds a good chance to cure diseases of unknown origin, such as perioral dermatitis. This study presents the results of three women with chronic perioral dermatitis that persisted for years with partial response to medical regimen. They asked for photodynamic treatment to ease off their suffering. The duration of follow-up was up to five years. Following PDT （photodynamic therapy）, the patients discontinued medications, redness decreased and eruption disappeared. In these patients, a single PDT treatment provided prolonged relief of perioral dermatitis for up to three years. These data are encouraging but not sufficient. Further study is warranted.展开更多

However, the anti-atopic dermatitis(AD) activity of BS has not been described yet. In the present study, we examined the preventive effect of BS on AD. The effect of oral administration of BS was tested in a 2, 4-dinitrofluorobenzene(DNFB)-induced AD animal model, by histological analysis, enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction, caspase-1 assay, and Western blotting analysis. BS administration reduced the total clinical severity and scratching frequencies, compared with the AD group. In the serum of DNFB-induced AD mice, the levels of IgE, histamine, thymic stromal lymphopoietin(TSLP), interleukin(IL)-5, and IL-13 were significantly reduced by BS treatment. BS significantly reduced the protein and mRNA expression of TSLP, IL-6, and tumor necrosis factor-α in the AD skin lesions. BS markedly reduced the infiltration of inflammatory cells. Furthermore, the activation of caspase-1 was reduced by BS in the AD skin lesions. Our results suggested that BS should be considered as a candidate treatment for allergic inflammatory diseases including AD.展开更多

Skin wound healing outcome was assessed by measuring skin thickness, weight(quality) of the skin, and trans-epidermal water loss(TEWL). Expression of AQP3 mRNA and protein was assessed by reverse transcriotion polymerase chain reaction(RT-PCR)and immunoblotting, respectively.RESULTS: Yupingfeng granule treatment resulted in significant acceleration of wound healing with63.64% efficiency, which was significantly higher than that of placebo granule treatment(31.82%,P < 0.01 by Wilcoxon Rank-sum test). Skin thickness, weight of the wounded skin, and TEWL were significantly higher in the AD models compared to that of normal animals. Treatment with Yupingfeng granules resulted in significant decrease in skin thickness [(937 ± 31) vs(360 ± 21) μm, P < 0.01],weight of the wounded skin [(42 ± 4) vs(24 ± 5)mg, P < 0.01], and TEWL [(30 ± 4) vs(13 ± 4) g·h^(-1)·m-2, P < 0.01]. Yupingfeng granules also significantly down-regulated mRNA and protein expression of AQP3 in the animal models.CONCLUSION: Our findings suggested that Yupingfeng granules could be used in AD treatment.展开更多

文摘Background:Wenqing Yin(WQY)is a classic prescription used to treat skin diseases like atopic dermatitis(AD)in China,and the aim of this study is to investigate the therapeutic effects and molecular mechanisms of WQY on AD.Methods:The DNFB-induced mouse models of AD were established to investigate the therapeutic effects of WQY on AD.The symptoms of AD in the ears and backs of the mice were assessed,while inflammatory factors in the ear were quantified using quantitative real-time-polymerase chain reaction(qRT-PCR),and the percentages of CD4^(+)and CD8^(+)cells in the spleen were analyzed through flow cytometry.The compounds in WQY were identified using ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)analysis and the key targets and pathways of WQY to treat AD were predicted by network pharmacology.Subsequently,the key genes were tested and verified by qRT-PCR,and the potential active components and target proteins were verified by molecular docking.Results:WQY relieved the AD symptoms and histopathological injuries in the ear and back skin of mice with AD.Meanwhile,WQY significantly reduced the levels of inflammatory factors IL-6 and IL-1βin ear tissue,as well as the ratio of CD4^(+)/CD8^(+)cells in spleen.Additionally,a total of 142 compounds were identified from the water extract of WQY by UPLC-Orbitrap-MS/MS.39 key targets related to AD were screened out by network pharmacology methods.The KEGG analysis indicated that the effects of WQY were primarily mediated through pathways associated with Toll-like receptor signaling and T cell receptor signaling.Moreover,the results of qRT-PCR demonstrated that WQY significantly reduced the mRNA expressions of IL-4,IL-10,GATA3 and FOXP3,and molecular docking simulation verified that the active components of WQY had excellent binding abilities with IL-4,IL-10,GATA3 and FOXP3 proteins.Conclusion:The present study demonstrated that WQY effectively relieved AD symptoms in mice,decreased the inflammatory factors levels,regulated the balance of CD4^(+)and CD8^(+)cells,and the mechanism may be associated with the suppression of Th2 and Treg cell immune responses.
文摘BACKGROUND Atopic dermatitis(AD),or eczema,is a chronic,pruritic inflammatory skin disease affecting children and adults.Socioeconomic status(SES)plays a significant role in developing AD.However,mixed evidence from a previous study by Bajwa et al makes it difficult to determine the directionality of the association.There is a lite-rature gap in understanding the causal association between AD and socioeco-nomic factors.AIM To evaluate the impact of disparities in SES on pediatric AD populations.METHODS Based on the eligibility criteria,the literature review identified eight articles since July 2021,and a descriptive analysis was conducted using an Excel spreadsheet on key components collected from the identified studies.RESULTS Eight observational studies assessed SES in pediatric AD.Five observational studies showed mixed associations between AD and SES.Sub-analysis revealed that urban areas had a higher prevalence of AD,and four studies identified a positive association between parental education and AD in the pediatric popu-lation.Socioeconomic variables,such as residential areas and household income,significantly influence disease outcomes.CONCLUSION There is mixed association between pediatric AD and SES,with AD positively associated with parental education.There is critical need to evaluate global impact of SES variables on pediatric AD.
文摘BACKGROUND Since the advent of the 20th century,alongside the progression of medical science and technological advancements,immunotherapy has emerged as a pivotal thera-peutic approach for tumor patients subsequent to undergoing radiotherapy and chemotherapy.Arimab(camrelizumab),a flagship drug in the realm of immuno-therapy,functions as a monoclonal antibody specifically targeting the progra-mmed death protein 1(PD-1).This drug engages with the human PD-1 receptor,effectively inhibiting the PD-1/programmed death ligand 1 signaling pathway.This inhibition results in the restoration of T cell activity and the induction of an anti-tumour response.However,it is noteworthy that such interference could lead to immune-related adverse events resembling autoimmune reactions.The grow-ing availability and clinical use of immune checkpoint inhibitors have raised sig-nificant clinical concerns regarding their safety.Numerous instances of immune-related adverse reactions and the associated management strategies have been extensively reported.Timely identification and diagnosis,coupled with multidi-sciplinary consultation and the prompt administration of immunosuppressants,can effectively address severe immune-related adverse reactions.CASE SUMMARY Arimab(camrelizumab),a monoclonal antibody targeting programmed death protein 1(PD-1),disrupts the PD-1/programmed death ligand 1(PD-L1)inter-action,reactivating T cell function and triggering anti-tumor immunity.However,this disruption may trigger immune-mediated adverse events akin to autoim-mune disorders.Approximately 2.8%of such events manifest as immune-related dermatologic reactions,with 0.7%classified as grade 3,which are infrequently documented.Here,this study describes a case of grade 3 bullous dermatitis occur-ring 15 days after initiating camrelizumab therapy.The patient,a 67-year-old male with oesophageal squamous cell carcinoma,received camrelizumab plus paclitaxel alongside chemotherapy and radiotherapy in early 2022.Due to disease progression,maintenance monotherapy with camrelizumab(200 mg)commenced in June 2022.On the fourth cycle,15 days into treatment,the patient presented with an immune-checkpoint inhibitor-related rash,despite unremarkable test results.Dermatology and pharmacy consultations were conducted,leading to glucocorticoid therapy,topical interventions,and supportive care.Gastric mucosal protection,nutritional supplementation,and other adjunctive treatments were also provided.The patient's symptoms resolved within 15 days post-discharge,resulting in discontinuation of camrelizumab.Like other PD-1 inhibitors,camrelizumab is associated with immune-mediated dermatitis.Thus,optimal management of these events requires a multidisciplinary approach,vigilant monitoring,regular evalua-tions,prompt glucocorticoid administration,and specialized dermatologic care.CONCLUSION The increasing adoption of immune checkpoint inhibitors in clinical practice has prompted substantial concerns about their safety profile.A wide range of immune-related adverse events and corresponding management stra-tegies have been well-documented.Early recognition and accurate diagnosis,combined with interdisciplinary collaboration and swift initiation of immunosuppressive therapy,are essential in managing severe immune-related adverse reactions effectively.This report details the treatment trajectory and outcome of a case involving immune-related cutaneous adverse reactions,providing pertinent clinical insights for future cases.
文摘Objective:This study aimed to investigate the association of atopic dermatitis(AD)and anxiety/depression behaviors induced by AD with the intestinal microbiota.Additionally,it sought to evaluate the therapeutic potential of mannan oligosaccharide(MOS)in alleviating AD symptoms through the modulation of the gut microbiota and the enhancement of short-chain fatty acids(SCFAs)production.Methods:Female Kunming mice were challenged with 2,4-dinitrofluorobenzene(DNFB)to induce AD-like symptoms.MOS was administered orally daily for 14 days.On the 6th and 11th days post-modeling,the number of scratching bouts in mice was recorded.Following dissection,epidermal thickness,mast cell infiltration,and serum levels of inflammatory cytokines were measured.Meanwhile,cerebral levels of neurotransmitters,including 5-hydroxytryptamine(5-HT)and norepinephrine(NE),were assessed.The abundance of intestinal microbiota and fecal concentrations of SCFAs were also analyzed.Results:MOS significantly reduced AD-like symptoms by reducing inflammatory cytokines,as reflected in a significant decrease in the number of scratching bouts,epidermal thickness,mast cells and inflammatory cytokine levels.MOS intervention up-regulated the expression of 5-HT and NE,and consequently alleviated anxiety and depression-like behaviors.Furthermore,compared with the AD group,MOS intervention increased the gut microbiota abundance of mice,especially beneficial bacteria such as Bifidobacterium,Lactobacillus and Klebsiella.At the same time,these beneficial bacteria significantly increased the fecal contents of SCFAs,especially propionic acid.Correlation analysis indicated that AD amelioration was positively correlated with fecal SCFAs levels and the proliferation of certain intestinal microbes.Conclusion:MOS intervention could offer a novel approach to managing AD and its psychological comorbidities.

文摘Objectives To investigate the barriers and facilitators influencing the sustainable implementation of evidence-based practice(EBP)for Peristomal Irritant Contact Dermatitis(PICD)based on the Consolidated Framework for Implementation Research(CFIR).Methods The sample consisted of 17 nurses from three urology wards at a tertiary hospital in Beijing,China,who had participated in the EBP.Guided by the CFIR,we identified constructs influencing the sustainability of implementation by conducting a directed content analysis of the 17 individual in-depth interviews.By rating,the valence and magnitude of each construct were determined.Results This study identified 19 factors across the five domains of the CFIR.Among these determinants,16 were identified as barriers,while three were recognized as facilitators.Common barriers across different contexts were identified,such as delayed evidence updating,the complexity of intervention components and steps,and incompatibility between the implementation process and clinical practices.In contrast,facilitators of intervention implementation were regular communication and feedback,support and drive from principals and a positive cultural atmosphere.In addition,we identified“regular evidence updating”as an independent construct outside of the CFIR,a finding that will provide key information for updating the CFIR framework.Conclusions Regular evidence updating is crucial for the sustainability of EBP implementation.Researchers should receive consistent feedback from practitioners and adjust or modify the EBP as necessary.Additionally,researchers must consider the compatibility or adaptability of the EBP’s content with clinical practice in formulating it rather than adding additional complexity to the original workflow.
文摘BACKGROUND Atopic dermatitis(AD)is a chronic inflammatory skin disease characterized by visible lesions that can lead to anxiety and depression.These psychological impacts may severely affect the physical and mental health and the overall quality of life of the affected individuals.AIM To identify the risk factors for anxiety and depression among patients with AD and to assess their influence on prognosis.METHODS A cross-sectional study was conducted in 273 patients with AD who visited Shanghai Jinshan Tinglin Hospital between July 2021 and June 2023.Data were collected using standardized instruments,including the general information questionnaire,hospital anxiety and depression scale,scoring AD index,and dermatology life quality index.RESULTS Among the evaluated patients,24.5%had symptoms of anxiety,and 19.8%had symptoms of depression.Independent risk factors for anxiety included lower education level[odds ratio(OR)=0.338,95%confidence interval(CI):0.183-0.625],increased number of medical visits(OR=2.300,95%CI:1.234-4.255),sleep disorders(OR=2.013,95%CI:1.032-3.923),and allergic rhinitis(OR=2.052,95%CI:1.097-3.839).Factors for depression included more severe pruritus(OR=6.837,95%CI:1.330-35.132),higher number of medical visits(OR=2.979,95%CI:1.430-6.205),sleep disorders(OR=2.245,95%CI:1.033-5.024),and asthma(OR=2.208,95%CI:1.003-4.859).Dermatology life quality index scores correlated positively with anxiety,depression,scoring AD index,sleep disorders,number of visits,and intensity of pruritus(P<0.05).CONCLUSION In patients with AD,anxiety and depression are associated with educational level,frequency of medical visits,sleep disorders,allergic rhinitis,pruritus,and asthma,all of which exacerbate symptoms and reduce quality of life.

文摘Objective:To assess the safety and topical efficacy of prim-O-glucosylcimifugin(POG)and investigate the molecular mechanisms of its therapeutic effects in atopic dermatitis(AD).Methods:The effects of POG on human keratinocyte cell viability and its anti-inflammatory properties were evaluated using cell counting kit-8 assay and reverse transcription-quantitative polymerase chain reaction(RT-qPCR).Subsequently,the impact of POG on the differentiation of cluster of differentiation(CD)4~+T cell subsets,including T-helper type(Th)1,Th2,Th17,and regulatory T(Treg),was examined through in vitro experiments.Network pharmacology analysis was used to elucidate POG's therapeutic mechanisms.Furthermore,the therapeutic potential of topically applied POG was further evaluated in a calcipotriol-induced mouse model of AD.The protein and transcript levels of inflammatory markers,including cytokines,lymphocyte-specific protein tyrosine kinase(Lck)mRNA,and LCK phosphorylation(p-LCK),were quantified using immunohistochemistry,RT-qPCR,and Western blot analysis.Results:POG was able to suppress cell proliferation and downregulate the transcription of interleukin 4(Il4)and Il13 mRNA.In vitro experiments indicated that POG significantly inhibited the differentiation of Th2 cells,whereas it exerted negligible influence on the differentiation of Th1,Th17 and Treg cells.Network pharmacology identified LCK as a key therapeutic target of POG.Moreover,the topical application of POG effectively alleviated skin lesions in the calcipotriol-induced AD mouse models without causing pathological changes in the liver,kidney or spleen tissues.POG significantly reduced the levels of Il4,Il5,Il13,and thymic stromal lymphopoietin(Tslp)m RNA in the AD mice.Concurrently,POG enhanced the expression of p-LCK protein and Lck mRNA.Conclusion:Our research revealed that POG inhibits Th2 cell differentiation by promoting p-LCK protein expression and hence effectively alleviates AD-related skin inflammation.
文摘Vitamin D,beyond its classical role in calcium homeostasis,has emerged as a key regulator of immune function and epithelial barrier integrity.Its deficiency during early childhood—a critical period for immune maturation—has been increasingly implicated in the development of atopic diseases.While extensively studied in asthma,its role in non-respiratory allergic conditions such as atopic dermatitis(AD)and allergic rhinitis(AR)remains comparatively underexplored.This minireview synthesizes current mechanistic and clinical evidence on vitamin D in pediatric AD and AR.In AD,vitamin D promotes epidermal barrier function through upregulation of filaggrin and ceramide synthesis,and enhances antimicrobial defense via induction of antimicrobial peptides.Observational studies consistently report lower serum 25-hydroxyvitamin D in affected children,particularly those with allergic sensitization.Select randomized controlled trials suggest clinical improvement with supplementation,especially at doses>2000 IU/day in deficient individuals.In AR,epidemiological data indicate stronger inverse associations with seasonal(pollen-induced)disease.Proposed mechanisms include modulation of dendritic cells,regulatory T cells,T helper 2 cytokines,and mucosal barrier integrity.The shared immunopathogenesis of AD and AR underscores vitamin D’s relevance.Although promising,clinical evidence remains heterogeneous.Future research should prioritize phenotype-stratified trials to clarify optimal dosing,timing,and individual response determinants,including genetics and microbiome composition.

文摘Background:Atopic dermatitis is a chronic inflammatory skin disorder characterized by recurrent eczema-like rashes and severe itching.Taxi San is an external herbal formulation with the effects of clearing heat,drying dampness,detoxifying,and relieving itching,making it suitable for treating acute and subacute dermatitis or eczema.Objectives:To evaluate the clinical efficacy of topical Taxi San in treating atopic dermatitis patients with dampness-heat syndrome and its inhibitory effect against Staphylococcus aureus(S.aureus)colonization.Methods:50 patients with atopic dermatitis were enrolled from the Dermatology Department of Shaanxi Provincial Hospital of Traditional Chinese Medicine,with bilateral symmetrical lesions selected as target sites.The control-side lesions were treated with boric acid solution wet compresses,while the treatment-side lesions received Taxi San solution wet compresses,both administered twice daily for 14 d.Clinical efficacy was evaluated using the Scoring Atopic Dermatitis(SCORAD),Investigator Global Assessment(IGA),Dermatology Life Quality Index/Children’s Dermatology Life Quality Index(DLQI/CDLQI),adverse events(AEs)and S.aureus colonization density,which were compared between the groups.The antibacterial efficacy of Taxi San was further investigated through in vitro antibacterial tests.Results:After 14 d of treatment with Taxi San,erythema and pimples were reduced on the treated sides.Additionally,the SCORAD,IGA,and DLQI/CDLQI scores showed significant decreases(P<0.05).S.aureus colonization on the treated sides declined markedly from 78%to 4.76%.Compared to the control sides,the reduction in S.aureus colonization following 14 d of Taxi San treatment was statistically significant(P<0.05).Furthermore,in vitro antibacterial assays demonstrated that the minimum inhibitory concentration of Taxi San against the seven tested S.aureus strains was 0.125 g/mL.Conclusions:Taxi San effectively reduces S.aureus colonization and ameliorates clinical symptoms in atopic dermatitis patients with dampness-heat syndrome,demonstrating high therapeutic potential and safety.
文摘Bacterial infections are quite common in dairy cattle,and frequently related to internal organ systems like e.g.respiratory,intestinal and udder infections.Lameness in dairy cattle is mainly caused by both infectious and non-infectious hoof problems and these have different etiological background.At the moment(2018)the major infectious hoof disorders are DD(Digital Dermatitis)and IP(Interdigital Phlegmon).These are all due to infection from the area where dairy cows normally live and more or less intensive contact with“contaminated”manure.This paper gives insight in these different dermatitis problems cows are daily confronted with,with a focus on infectious hoof disorders as a more or less permanent problem in today’s dairy farming.
文摘Some patients with perioral dermatitis are not relieved despite many medications. These patients confront pain, psychological bother and social/occupational limitations. Being efficient for a wide variety of diseases including infectious inflammative degenerative or tumoral, photodynamic therapy holds a good chance to cure diseases of unknown origin, such as perioral dermatitis. This study presents the results of three women with chronic perioral dermatitis that persisted for years with partial response to medical regimen. They asked for photodynamic treatment to ease off their suffering. The duration of follow-up was up to five years. Following PDT （photodynamic therapy）, the patients discontinued medications, redness decreased and eruption disappeared. In these patients, a single PDT treatment provided prolonged relief of perioral dermatitis for up to three years. These data are encouraging but not sufficient. Further study is warranted.

文摘Bamboo salt(BS) is a traditional Korean food, and has been reported to have anti-cancer, anti-inflammatory, and anti-metastatic effects. However, the anti-atopic dermatitis(AD) activity of BS has not been described yet. In the present study, we examined the preventive effect of BS on AD. The effect of oral administration of BS was tested in a 2, 4-dinitrofluorobenzene(DNFB)-induced AD animal model, by histological analysis, enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction, caspase-1 assay, and Western blotting analysis. BS administration reduced the total clinical severity and scratching frequencies, compared with the AD group. In the serum of DNFB-induced AD mice, the levels of IgE, histamine, thymic stromal lymphopoietin(TSLP), interleukin(IL)-5, and IL-13 were significantly reduced by BS treatment. BS significantly reduced the protein and mRNA expression of TSLP, IL-6, and tumor necrosis factor-α in the AD skin lesions. BS markedly reduced the infiltration of inflammatory cells. Furthermore, the activation of caspase-1 was reduced by BS in the AD skin lesions. Our results suggested that BS should be considered as a candidate treatment for allergic inflammatory diseases including AD.

文摘OBJECTIVE: To investigate effect of Yupingfeng granules, prepared with Chinese Medicines, on the wound healing and on the expression of aquaporin3(AQP3) and the skin barrier in the animal models of atopic dermatitis(AD).METHODS: Acute skin lesions of AD models were prepared using 2,4-dinitrochlorobenzo(DNCB) in mice and animals were treated with either Yupingfeng granules or placebo for two weeks. Skin wound healing outcome was assessed by measuring skin thickness, weight(quality) of the skin, and trans-epidermal water loss(TEWL). Expression of AQP3 mRNA and protein was assessed by reverse transcriotion polymerase chain reaction(RT-PCR)and immunoblotting, respectively.RESULTS: Yupingfeng granule treatment resulted in significant acceleration of wound healing with63.64% efficiency, which was significantly higher than that of placebo granule treatment(31.82%,P < 0.01 by Wilcoxon Rank-sum test). Skin thickness, weight of the wounded skin, and TEWL were significantly higher in the AD models compared to that of normal animals. Treatment with Yupingfeng granules resulted in significant decrease in skin thickness [(937 ± 31) vs(360 ± 21) μm, P < 0.01],weight of the wounded skin [(42 ± 4) vs(24 ± 5)mg, P < 0.01], and TEWL [(30 ± 4) vs(13 ± 4) g·h^(-1)·m-2, P < 0.01]. Yupingfeng granules also significantly down-regulated mRNA and protein expression of AQP3 in the animal models.CONCLUSION: Our findings suggested that Yupingfeng granules could be used in AD treatment.

文摘Objective:To study the therapeutic mechanisms of pseudolaric acid on allergic contact dermatitis in mice.Methods:A total of 50 BALB/C mice were selected and randomly divided into control group,model group,and treatment A,B,C groups with 10 rats in each group.ACD model was established in model group,and treatment A,B,C groups but not in control group.Model group received no treatment,but treatment A,B,C groups were treated with external application of the concentration of 0.1%,0.2% and 0.4% of the pseudolaric acid for the lesions of ear skin.And the weight gain and the swelling degree of the mice' ear were recorded,weight of thymus and spleen were measured.Spleen suspension was prepared to test T lymphocyte and B lymphocyte levels of mice in five groups.Changes in serum IFN-ed through the enzyme linked immunosorbent assay(ELISAγ,IL-4 and IL-10 levels were test).Results:The weight gain of mice in model group were significant lower than those of mice in the control group and the treatment A,B,C groups(P<0.05).Weight gain of mice in treatment A,B groups were significant lower than that of control group(P<0.05),but the difference in weight gain between treatment C group and control group showed no significant difference(P>0.05).The swelling degree and the weight of mice ears in model group were significant higher than those of mice in control group and treatment A,B,C groups(P<0.05).Swelling degree and the weight of mice ears of treatment A,B,C groups were obviously higher than that of control group(P<0.05).The swelling degree and weight of mice' ears in treatment A,B,C groups were decreased with the increase of the drug dosage,but comparison between A,B and C group showed statistically differences(P<0.05).The thymus and spleen index of mice in model group were significant higher than those of the other four groups(P<0.05),among the four groups,thymus and spleen index of treatment A and B group were higher than control group and treatment C group(P<0.05).The stimulation index of T and B cells of mice in model group was significantly higher than the rest four groups(P<0.05).The serum IFN-γ level of mice in control group and treatment A,B and C group was obviously lower than that of mice in model group(P<0.05).The serum IFN-γ level of mice in treatment A,B and C group were decreased with the increasing of the drug dosage,and the level of C group was obviously lower than that of A and B group(P<0.05).Conclusion:The pseudolaric acid has anti-inflammation and immune adjustment the effects showing a remarkable therapeutic effects for the ACD mice.
