Background: Photodynamic therapy (PDT) is a successful treatment for non-melanoma skin cancers in clinical practice. In China, more and more doctors use PDT to cure the patients with skin cancer, especially in the elder. The purpose of this study was to evaluate the efficacy of topical PDT using aminolevulinic acid (5-ALA) combined with excision in the treatment of skin malignant tumor and its role in surgical improvements.
Methods: A total of 58 cases including 32 cases of BCC, 13 cases of Bowen's disease, 8 cases of Paget's disease and 5 cases of SCC were included in this study. All cases were treated with topical ALA-PDT after surgery. Each tumor region was irradiated with 120 J/cm(2) using a 635-nm laser for 15 min. A total of 3 times of assisted ALA-PDT was applied after surgery.
Results: There was no recurrence in 6 months after treatment. Only 5 cases of Paget's disease and 2 cases of SCC experienced disease recurrence in 1 year. All patients were able to complete the treatment protocol, with well cosmetic results and no moderate adverse reactions.
Conclusions: As an assistive therapy after tumor resection, ALA-PDT can reduce the excision range of the tumor lesions. However, its role in the reduction of recurrence rate remains to be further investigated.

Pathogenic activating mutations in the fibroblast growth factor receptor 3 (FGFR3) drive disease maintenance and progression in urothelial cancer. 10-15% of muscle-invasive and metastatic urothelial cancer (MIBC/mUC) are FGFR3-mutant. Selective targeting of FGFR3 hotspot mutations with tyrosine kinase inhibitors (e.

The 2015-2016 Zika virus (ZIKV) outbreak in the Americas revealed the ability of ZIKV from the Asian lineage to cause birth defects, generically called congenital Zika syndrome (CZS). Notwithstanding the long circulation history of Asian ZIKV, no ZIKV-associated CZS cases were reported prior to the outbreaks in French Polynesia (2013) and Brazil (2015). Whether the sudden emergence of CZS resulted from an evolutionary event of Asian ZIKV has remained unclear.

Zoonotic infections (swine-human) caused by influenza A viruses (IAVs) have been reported and linked to close contact between these species. Here, we describe eight human IAV variant infections (6 mild and 2 severe cases, including 1 death) detected in Paraná, Brazil, during 2020-2023. Genomes recovered were closely related to Brazilian swIAVs of three major lineages (1 A.

Associations of adiposity with risks of oesophageal squamous cell carcinoma (ESCC) and non-cardia stomach cancer, both prevalent in China, are still inconclusive. While adiposity is an established risk factor for colorectal cancer, the relevance of fat-free mass and early-adulthood adiposity remains to be explored. The prospective China Kadoorie Biobank study included 0.
