A case of acquired syphilis in an infant through mouth-to-mouth transmission of prechewed food.

Background: Patients with syphilis are the only source of infection, which can be transmitted through sexual contact and mother-to-child and blood transmission, and rarely through contaminants. The clinical manifestations of syphilis are complex and variable, and can be easily misdiagnosed. This article reports a case of syphilis in a child with "psoriasis"-like lesions who was fed pre-chewed food.

Study on heart rate recovery index to predict maximum oxygen uptake in healthy adults aged 30 to 60 years old.

Objective: To explore the feasibility of post-exercise heart rate recovery indicators for predicting maximum oxygen uptake (VO2max) in healthy adults aged 30-60 years.

Methods: 260 healthy adults who did not perform regular exercise were randomly recruited and divided into a model group (n = 200) and a verification group (n = 60). Measure body fat percentage, weight, height and other indicators, and complete a cardiopulmonary exercise test as required to measure VO2max and heart rate recovery (HRR1, HRR2) in the first and second minutes after exercise.

A general strategy towards activatable nanophotosensitizer for phototoxicity-free photodynamic therapy.

Photodynamic therapy (PDT) has gained widespread attention in cancer treatment, but it still faces clinical problems such as skin phototoxicity. Activatable photosensitizers offer a promising approach to addressing this issue. However, several significant hurdles need to be overcome, including developing effective activation strategies and achieving the optimal balance between photodynamic effects and related side effects.

CHD1L accelated the progression of cutaneous squamous cell carcinoma via promoting PI3K/PD-L1 signaling pathway induced M2 polarization of TAMs.

To investigate CHD1L's impacts and molecular processes in hypoxic cutaneous squamous cell carcinoma. Monoclonal proliferation assays and CCK-8 were used to detect the proliferation capacity of A431 cells and Colon16 cells; wound healing experiments and Transwell assays were used to examine the migration and invasion capacity of A431 cells and Colon16 cells; angiogenesis experiments were conducted to assess the influence of A431 cells on angiogenesis; a nude mouse tumor xenograft experiment and HE staining were utilized to evaluate the impact of CHD1L on the progression of cutaneous squamous cell carcinoma; western blot analysis was performed to detect the expression of p-PI3K, p-AKT, and PD-L1 in A431 cells, as well as CD9, TSG101, PD-L1 in exosomes, and CD206, Arginase-1, iNOS, IL-1β, p-AKT, p-mTOR, VEGF, COX-2, MMP2, MMP9, p-ERK1/2 in tumor-associated macrophages. Under hypoxic conditions, CHD1L promoted the proliferation, migration, invasion, and angiogenesis of cutaneous squamous cell carcinoma.
