BACKGROUND Eccrine porocarcinoma(EPC)is a rare skin tumor that mainly affects the elderly population.Tumors often present with slow growth and a good prognosis.EPCs are usually distinguished from other skin tumors using histopathology and immunohistochemistry.However,surgical management alone may be inadequate if the tumor has metastasized.However,currently,surgical resection is the most commonly used treatment modality.CASE SUMMARY A seventy-four-year-old woman presented with a slow-growing nodule in her left temporal area,with no obvious itching or pain,for more than four months.Histopathological examination showed small columnar and short spindle-shaped cells;thus,basal cell carcinoma was suspected.However,immunohistochemical analysis revealed the expression of cytokeratin 5/6,p63 protein,p16 protein,and Ki-67 antigen(40%),and EPC was taken into consideration.The skin biopsy was repeated,and hematoxylin and eosin staining revealed ductal differentiation in some cells.Finally,the patient was diagnosed with EPC,and Mohs micrographic surgery was performed.We adapted follow-up visits in a year and not found any recurrence of nodules.CONCLUSION This case report emphasizes the diagnosis and differentiation of EPC.

Cutibacterium acnes in Atopic Dermatitis: Roles and Potential Therapeutic Applications

引用

International Journal of dermatology And Venereology 2024年第1期07卷 12-17页

作者： Yu Tian-Ze Li Wei department of dermatology Shanghai Institute of dermatology Huashan Hospital Fudan University Shanghai 200040 China

Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease. The main initiating mechanisms of AD are disruptions in the skin microbiota, dysfunction of the skin barrier, and predominantly elevated type 2 immune responses.Cutibacterium acnes (C. acnes) is a commensal bacterium that is ubiquitous and predominant in healthy skin and shows intraspecific subtype diversity. The abundance ofC. acnes is closely related to the sebum secreted by sebaceous glands.C. acnes has long been considered a proinflammatory skin bacterium that drives the development of acne vulgaris. Growing evidence indicates thatC. acnes promotes skin microbiota homeostasis and skin barrier maintenance; however, the potential role ofC. acnes in AD remains largely unexamined. This review provides the latest information on the distribution ofC. acnes and its phylotypes in healthy skin and AD as well as an overview of the possible role ofC. acnes in the pathophysiological pathways underlying AD. Additionally, the review focuses on new evidence regarding the protective functions ofC. acnes and its metabolites in AD and discusses the potential for therapeutic applications.

Hydroxysafflor Yellow A Promotes HaCaT Cell Proliferation and Migration by Regulating HBEGF/EGFR and PI3K/AKT Pathways and Circ_0084443

引用

Chinese Journal of Integrative Medicine 2024年第3期30卷 213-221页

作者： ZHANG Yue XIAO Yan-wei MA Jing-xin WANG Ao-xue department of dermatology the Second Hospital of Dalian Medical UniversityDalianLiaoning Province116021China department of Cell Biology Dalian Medical UniversityDalianLiaoning Province116044China

Objective:To investigate the effect and possible mechanism of hydroxysafflor yellow A(HSYA) on human immortalized keratinocyte cell proliferation and migration.Methods:HaCaT cells were treated with HSYA.Cell proliferation was detected by the cell counting kit-8 assay,and cell migration was measured using wound healing assay and Transwell migration assay.The mRNA and protein expression levels of heparin-binding epidermal growth factor(EGF)-like growth factor(HBEGF),EGF receptor(EGFR),phosphatidylinositol 3-kinase(PI3K),protein kinase B(AKT),mammalian target of rapamycin(mTOR),and hypoxia-inducible factor-1α(HIF-1α) were detected by quantitative real-time polymerase chain reaction(qRT-PCR) and Western blot,respectively.Circ_0084443-overexpressing HaCaT cells and empty plasmid HaCaT cells were constructed using the lentiviral stable transfection and treated with HSYA.The expression of circ_0084443 was detected by qRT-PCR.Results:HSYA(800 μmol/L) significantly promoted HaCaT cell proliferation and migration(P0.05).Conclusion:HSYA played an accelerative role in HaCaT cell proliferation and migration,which may be attributable to activating HBEGF/EGFR and PI3K/AKT signaling pathways,and had a particular inhibitory effect on the keratinocyte negative regulator circ_0084443.

Chinese Journal of Integrative Medicine 2024年第3期30卷 222-229页

作者： ZHANG Shuo LI Hong-jin YANG Chun-mei LIU Liu SUN Xiao-ying WANG Jiao CHEN Si-ting LU Yi HU Man-qi YAN Ge ZHOU Ya-qiong MIAO Xiao LI Xin LI Bin department of dermatology Yueyang Hospital of Integrated Traditional Chinese and Western MedicineShanghai University of Traditional Chinese MedicineShanghai200437China Institute of dermatology Shanghai Academy of Traditional Chinese MedicineShanghai201203China department of Integrated Traditional Chinese and Western Medicine Shanghai Skin Disease HospitalTongji University School of MedicineShanghai200443China

Objective:To determine the role of Tripterygium wilfordii multiglycoside(TGW) in the treatment of psoriatic dermatitis from a cellular immunological perspective.Methods:Mouse models of psoriatic dermatitis were established by imiquimod(IMQ).Twelve male BALB/c mice were assigned to MQ or IMQ+TGW groups according to a random number table.Histopathological changes in vivo were assessed by hematoxylin and eosin staining.Ratios of immune cells and cytokines in mice,as well as PAM212 cell proliferation in vitro were assessed by flow cytometry.Pro-inflammatory cytokine expression was determined using reverse transcription quantitative polymerase chain reaction.Results:TGW significantly ameliorated the severity of IMQ-induced psoriasis-like mouse skin lesions and restrained the activation of CD45^(+)cells,neutrophils and T lymphocytes(all P<0.01).Moreover,TGW significantly attenuated keratinocytes(KCs) proliferation and downregulated the mRNA levels of inflammatory cytokines including interleukin(IL)-17A,IL-23,tumor necrosis factor α,and chemokine(C-X-C motif) ligand 1(P<0.01 or P<0.05).Furthermore,it reduced the number of γδ T17 cells in skin lesion of mice and draining lymph nodes(P<0.01).Conclusions:TGW improved psoriasis-like inflammation by inhibiting KCs proliferation,as well as the associated immune cells and cytokine expression.It inhibited IL-17 secretion from γδ T cells,which improved the immune-inflammatory microenvironment of psoriasis.
