The blood-brain barrier (BBB) and drug resistance present challenges for chemotherapy of glioblastoma (GBM). A microneedle (MN) patch with excellent biocompatibility and biodegradability was designed to bypass the BBB and release temozolomide (TMZ) and PLCG1-siRNA directly into the tumor site for synergistic treatment of GBM. The codelivery of TMZ and PLCG1-siRNA enhanced DNA damage and apoptosis. The potential mechanism behind this enhancement is to knockdown of PLCG1 expression, which positively regulates the expression of signal transducer and activator of transcription 3 genes, thereby preventing DNA repair and enhancing the sensitivity of GBM to TMZ. The MN patch enables long-term sustainable drug release through implantation and increases local drug concentrations in diseased areas, significantly extending mouse survival time compared to other drug treatment groups. MN drug delivery provides a platform for the combination treatment of GBM and other central nervous system diseases.

Adeno-associated viruses (AAV) have significant potential as vaccine carriers due to their excellent biosafety and efficient antigen gene delivery. However, most AAV vaccines show limited capacity to transduce antigen-presenting cells (APCs) following intramuscular injection which may cause inadequate cellular immune responses and undesired side effects due to transducing other tissues or cells. Herein, we developed a soluble microneedle patch for targeting the AAV vaccines to the epidermal and dermal APCs.

Recently, photodynamic therapy (PDT) which involves a photosensitizer (PS), a special drug activated by light, and light irradiation has been widely used in treating various skin diseases such as port-wine stain as well as cancers such as melanoma and non-melanoma skin cancers. PDT comprises two general steps: the introduction of PS into the body or a specific spot to be treated, and the irradiation process using a light source with a specific wavelength to excite the PS. Although PDT is gaining great attention owing to its potential as a targeted approach in the treatment of skin cancers, several limitations still exist for practical use.

In this study, a sensitive diagnosis and spontaneously photocatalytic therapy of cancer based on chemiluminescence (CL) and nanozyme was studied. Briefly, carbon nitride-supported copper nanoparticles (CuCNs) loaded with luminol (CuCN-L) were utilized to develop a microneedle patch (CuCN-L/MN). The CuCN-L probe could target overexpressed HO in the TME and actively emit CL to achieve cancer cell imaging for diagnosis.

Aim: To present three cases of filler-induced alopecia (FIA) and summarize the current knowledge of its clinical features, mechanisms and treatments.
Methods: In the first two cases, two females developed well-defined triangular patches of hair loss after hyaluronic acid (HA) injections, and received corticosteriod injections with topical 5% minoxidil. The third case described another female who experienced alopecia areata-like hair loss after autologous fat grafting, and received combined therapies including corticosteriod, 5% minoxidil and microneedling.
