Background: Lichenoid vulvar dermatoses (LVD) are inflammatory diseases primarily affecting the vulva and anus. This study aims to evaluate the skin changes in patients with LVD using high‐frequency ultrasound. Methods: Forty‐five patients with LVD, who attended Henan Provincial People's Hospital from November 2021 to March 2024, were selected. According to the pathological conclusions, patients were divided into two groups: the vulvar lichen sclerosus (VLS) group (n = 24) and the vulvar lichen simplex chronicus (VLSC) group (n = 21). Thirty age‐ and BMI‐matched healthy women were selected as the control group. We assessed the epidermal thickness, subepidermal low echogenic band (SLEB) thickness, dermal thickness, and vascular index (VI) among the three groups. Receiver operating characteristic curve (ROC) analysis was performed to determine the diagnostic efficacy of these ultrasound parameters for LVD. Binary logistic regression was used to investigate risk factors influencing LVD pathology in VLS patients. Results: Epidermal thickness, SLEB thickness, dermal thickness, and VI were increased in the VLS and VLSC groups compared to the control group (p < 0.05). There were no statistically significant differences in ultrasound parameters between the VLS and VLSC groups (p > 0.05). The ROC curves showed that the area under the curve (AUC) value for the dermis (AUC = 0.882) was the largest for VLS, and VI (AUC = 0.917), it was the largest for VLSC. Binary logistic regression indicated that having an allergic disease was a risk factor for VLS between VLS and VLSC groups (OR = 6.797, p = 0.028). Conclusion: High‐frequency ultrasound can detect thickening of the skin and increasing VI in patients with LVD, which can be helpful in the evaluation and management of LVD. [ABSTRACT FROM AUTHOR]

Consistent with global trends in cultural tourism, museum tourism has emerged as a popular form of cultural tourism that has increasingly drawn the significant attention of scholars as the target of academic research. The tourists' cultural experience can affect their evaluation of the specific visit and subsequent behavior. While previous researchers have paid more attention to the mechanism of visitors' post-visit behaviors, cultural transmission as a dependent variable has received scarce attention. This study examines factors influencing college students' behavior in communicating specific museum cultural content after a visit. It also identifies the mediating mechanism underlying the relationships between cultural transmission and its antecedents. The purposive questionnaire in a highly structured survey was distributed online among college students. A total of 195 usable responses were drawn. A quantitative survey methodology was employed, including Chi-square analysis, Confirmatory Factor Analysis, and Structural Equation Modeling. The results show that: (1) the determinants of college students' cultural transmission behavior are cultural experience, cultural identity, and satisfaction, which explains 59% of the variance of cultural transmission; (2) the impact of cultural experience on cultural transmission was mediated by cultural identity and satisfaction (it includes a serial mediation effect as the effect of cultural experience on satisfaction flowed through cultural identity, where student satisfaction mediated the impact of cultural identity on cultural transmission); and (3) college students pursuing the liberal arts present statistically different preferences in visiting museums when compared with science and engineering students. The discussion and implications present theoretical advancements in elucidating the mechanism of visitors' cultural communication processes and recommend the use of technology-driven innovations for improvements in post-visit activities for cultural transmission.

Ultrasmall CoSe2 nanoparticles encapsulated by an N-doped carbon matrix were prepared by selenizing a novel Co-metal organic framework precursor. The excellent electrochemical performance may be due to the synergistic effect of the N-doped carbon matrix and the ultrasmall CoSe2. [ABSTRACT FROM AUTHOR]
