Abstract
INTRODUCTION Narrow-band ultraviolet B (NB-UVB) phototherapy has been used for the treatment of chronic urticaria (CU), but the clinical efficacy of this treatment modality requires further evidence. A systematic review and meta-analysis of randomized clinical trials were conducted to evaluate the efficacy and safety of NB-UVB as add-on therapy in the treatment of CU. METHODS A literature search was conducted in the Cochrane, Embase, PubMed, Web of Science, CNKI, CBM, VIP and WanFang databases up to October 2020. A total of nine studies involving 713 participants met the inclusion criteria. RESULTS Two trials showed a significant difference in the Urticaria Activity Score between therapy with NB-UVB + antihistamines and that with antihistamines alone (mean difference 8.23, 95% confidence interval [CI] 5.78-10.68, p < 0.00001). Six trials (563 participants) showed a significant benefit of NB-UVB as add-on therapy to antihistamines in the total effective rate (risk ratio [RR] 1.56, 95% CI 1.39-1.75, p < 0.00001). In terms of adverse events, no statistically significant differences were found for NB-UVB + antihistamines versus antihistamines alone (RR 1.10, 95% CI 0.67-1.79, p = 0.71). Combination therapy of NB-UVB + antihistamines yielded a significantly lower risk of recurrence (RR 0.25, 95% CI 0.14-0.44, p < 0.00001). CONCLUSION Our meta-analysis suggests that combination therapy of NB-UVB + antihistamines is significantly more effective in treating CU than antihistamines alone.

Antifibrotic effects of Hypocrellin A combined with LED red light irradiation on keloid fibroblasts by counteracting the TGF-β/Smad/autophagy/apoptosis signalling pathway. Photodiagnosis Photodyn Ther 2021; 34:102202. [PMID: 33556618 DOI: 10.1016/j.pdpdt.2021.102202] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 01/21/2021] [Accepted: 01/25/2021] [Indexed: 11/23/2022]
Abstract
Keloids are characterized by abnormal proliferation of fibroblasts and continuous deposition of extracellular matrix (ECM) components. In the field of dermopathy, photodynamic therapy (PDT) with visible light has been increasingly investigated. The natural photosensitizer Hypocrellin A (HA) was shown to have excellent light induced anticancer, antimicrobial and antiviral activities. In this experiment, we investigated the impacts of HA united light-emitting diode (LED) red light irradiation on human keloid fibroblast cells (KFs). Our results showed that HA combined with red light irradiation treatment (HA-R-PDT) decreased KF viability, reduced KF collagen production and ECM accumulation, inhibited cell proliferation, suppressed cell invasion and induced cell apoptosis. Moreover, our observations demonstrated that the TGF-β/Smad signalling pathway and autophagy were restrained by HA-R-PDT. TGF-β1 could promote autophagy in KFs through both the Smad and ERK pathways, while inhibition of autophagy altered the TGF-β1 levels through negative feedback. Therefore, HA-R-PDT suppressed cell hyperproliferation, collagen synthesis and ECM accumulation of KFs by regulating the TGF-β1-ERK-autophagy-apoptosis signalling pathway. HA-R-PDT deserves systematic investigation as a potential therapeutic strategy for keloids, and autophagy might be a promising candidate in the treatment of KFs.

Abstract
BACKGROUD The biological effect of phototherapy, which involves using visible light for disease treatment, has attracted recent attention, especially in dermatological practice. Light-emitting diode (LED) irradiation increases dermal collagen level and reduces inflammation. It has been suggested that thermal therapy and LED irradiation can modulate inflammatory processes. However, little is known about the molecular mechanism of the anti-inflammatory effects of thermal therapy and LED irradiation. OBJECTIVE This study was to determine the anti-inflammatory effect of thermal therapy combined with LED irradiation on trimellitic anhydride (TMA)-induced acute contact hypersensitivity (CHS) mouse model. METHODS Twenty-four BALB/c mice were randomly divided into the following groups: Vehicle group, TMA group, TMA + alternating thermal therapy group (Alternating group), and TMA + alternating + LED group (LED group). Ear swelling was measured based on the thickness of ear before and after each TMA challenge. Vascular permeability was evaluated by the extravasation of Evans blue dye. Serum IgE level, Th1/Th2/Th17 cytokines, and related transcription factors were measured using ELISA kits, and histological examination was illustrated in ear tissue. RESULTS The LED group showed reduction in ear swelling response, vascular permeability, serum IgE levels, Th2/Th17 cytokine levels, and inflammatory cell infiltration. Moreover, the LED group showed increased Th1 cytokine levels. CONCLUSIONS These results indicate that thermal therapy combined with LED irradiation alleviated TMA-induced acute CHS in the mouse model. Thermal therapy and phototherapy should be considered as a novel therapeutic tool for the treatment of skin inflammation.

Abstract
BACKGROUND Visible light is absorbed by photoacceptors in pigmented and non-pigmented mammalian cells, activating signaling cascades and downstream mechanisms that lead to the modulation of cellular processes. Most studies have investigated the molecular mechanisms and therapeutic applications of UV and the red to near infrared regions of the visible spectrum. Considerably less effort has been dedicated to the blue, UV-free part of the spectrum. OBJECTIVE In this review, we discuss the current advances in the understanding of the molecular photoacceptors, signaling mechanisms, and corresponding therapeutic opportunities of blue light photoreception in non-visual mammalian cells in the context of inflammatory skin conditions. METHODS The literature was scanned for peer-reviewed articles focusing on the molecular mechanisms, cellular effects, and therapeutic applications of blue light. RESULTS At a molecular level, blue light is absorbed by flavins, porphyrins, nitrosated proteins, and opsins; inducing the generation of ROS, nitric oxide release, and the activation of G protein coupled signaling. Limited and contrasting results have been reported on the cellular effects of blue light induced signaling. Some investigations describe a regulation of proliferation and differentiation or a modulation of inflammatory parameters; others show growth inhibition and apoptosis. Regardless of the elusive underlying mechanism, clinical studies show that blue light is beneficial in the treatment of inflammatory skin conditions. CONCLUSION To strengthen the use of blue light for therapeutic purposes, further in depth studies are clearly needed with regard to its underlying molecular and cellular mechanisms, and their translation into clinical applications.

IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2018; 21:1133-1139. [PMID: 30483386 PMCID: PMC6251399 DOI: 10.22038/ijbms.2018.30284.7304] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/04/2018] [Accepted: 07/16/2018] [Indexed: 12/23/2022]
Abstract
OBJECTIVES Photo-thermal therapy (PTT) is a therapeutic method in which photon energy is converted into heat to induce hyperthermia in malignant tumor cells. In this method, energy conversion is performed by nanoparticles (NPs) to enhance induced heat efficacy. The low-cytotoxicity and high optical absorbance of NPs used in this technique are very important. In the present study, titanium dioxide (TiO2) NPs were used as agents for PTT. For increasing water dispersibility and biocompatibility, polyethylene glycol (PEG)-TiO2 NPs (PEGylated TiO2 NPs) were synthesized and the effect of these NPs on reducing melanoma tumor size after PTT was experimentally assessed. MATERIALS AND METHODS To improve the dispersibility of TiO2 NPs in water, PEG was used for wrapping the surface of TiO2 NPs. The formation of a thin layer of PEG around the TiO2 NPs was confirmed through thermo-gravimetric analysis and transmission electron microscopy techniques. Forty female cancerous mice were divided into four equal groups and received treatment with NPs and a laser diode (λ = 808 nm, P = 2 W & I = 2 W/cm2) for seven min once in the period of the treatment. RESULTS Compared to the mice receiving only the laser therapy, the average tumor size in the mice receiving TiO2-PEG NPs with laser excitation treatment sharply decreased. CONCLUSION The results of animal studies showed that PEGylated TiO2 NPs were exceptionally potent in destroying solid tumors in the PTT technique.
