Background: Keloid, a prevalent pathological skin lesion, presents significant challenges in terms of treatment efficacy. Photodynamic therapy (PDT), an increasingly popular adjuvant treatment, has shown significant potential in the management of various disorders, including cancer. However, the therapeutic potential of indocyanine green-mediated photodynamic therapy (ICG-PDT) for keloids has not yet been demonstrated.

Cyclic dinucleotides (CDNs) are a promising class of immune agonists that trigger the stimulator of interferon genes (STING) to activate both innate and acquired immunity. However, the efficacy of CDNs is limited by drug delivery barriers. Therefore, we developed a combined immunotherapy strategy based on injectable reactive oxygen species (ROS)-responsive hydrogels, which sustainably release 5,6-dimethylxanthenone-4-acetic acid (DMXAA) as known as a STING agonist and indocyanine green (ICG) by utilizing a high level of ROS in the tumor microenvironment (TME).

The morbidity and mortality of melanoma which accounts for 90% of cutaneous neoplasm-related deaths is growing over the last few decades. Common treatments for melanoma are limited to poor tissue selectivity, high toxicity and drug resistance. Photodynamic therapy (PDT) is an effective adjuvant therapy and could be a promising therapy for melanoma.

Multimodality imaging-guided therapy can improve the diagnostics and therapeutics efficiency of cancer. Herein, we developed a light-responsive nanotheranostic agent based on the indocyanine green (ICG) conjugated mesoporous silica coated gold nanobipyramid (GNB@SiO) (denoted as GNB@SiO-ICG) for simultaneous fluorescence (FL)/photoacoustic (PA) imaging-guided photothermal therapy (PTT). The GNB@SiO with excellent photostability was used for PA imaging as well as PTT.

Background: Intralesional injection of triamcinolone acetonide is an effective method for treating keloids. It still lacks effective and objective evaluation methods. This study aimed to observe the efficacy of intralesional triamcinolone acetonide injections for the treatment of keloids and to explore the role of high-frequency ultrasound in the monitoring and evaluation of keloids therapy.

Vitiligo is a common depigmentary disease characterized as diagnosis simplicity and cure difficulty in view of the ambiguity of etiology, thus novel and effective treatments are urgently needed. Paeoniflorin, the major active compound extracted from the root of Paeonia lactiflora Pall, a traditional Chinese medicine, has been validated pharmacological properties such as antioxidant stress, a theory participating in the occurrence of vitiligo, but the effect on melanogenesis is still unclear. In this study, melanosythesis effect of paeoniflorin and the potential mechanism were evaluated.

Puerarin is the major bioactive ingredient derived from the root of the Pueraria lobata (Willd.), and its antioxidative stress effects have been demonstrated in several previous studies. Moreover, Puerarin can upregulate melanin synthesis and microphthalmia-associated transcription factor (MITF) transcription by increasing cAMP level of intracellular cyclic adenosine monophosphate.
