RESUMO

Metabolic abnormalities and uncontrolled angiogenesis are two vital features of malignant tumors. Although fibroblast growth factor 6 (FGF6) is known to promote the proliferation and migration of bladder cancer (BC) cells, its influences on aerobic glycolysis and angiogenesis in BC remain unclear. Gene expression at messenger RNA and protein levels were examined by reverse transcription-quantitative polymerase chain reaction and Western blot analyses, respectively. Lactate production and glucose uptake in BC cells were evaluated by performing aerobic glycolysis assays. A vasculogenic mimicry assay was executed for assessing the angiogenesis of BC cells. The viability, migration, and angiogenesis of human umbilical vein endothelial cells (HUVECs) cocultured with supernatants of BC cells were detected using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, wound healing assay, and tube formation assay. It was found that FGF6 displayed a high level in BC cell lines. Silencing of FGF6 reduced the levels of lactate production, glucose uptake, and the expression of angiogenic factors and glycolytic enzymes in BC cells, which also inhibited the viability and migration of HUVECs. In addition, FGF6 depletion or aerobic glycolysis inhibitor 2-deoxy-d-glucose treatment decreased the total branching length and intersection number of both BC cells and HUVECs. Moreover, glucose or lactate treatment reversed FGF6-induced suppression of cell viability, migration, tube formation, and vasculogenic mimicry. The activation of the phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt) and mitogen-activated protein kinase (MAPK) signaling pathways was blocked by silenced FGF6. Furthermore, PI3K/Akt inhibitor (LY2940002) and p38-MAPK inhibitor (SB203580) inhibited the levels of aerobic glycolysis-related proteins. In conclusion, FGF6 knockdown suppressed aerobic glycolysis, thereby inhibiting angiogenesis in BC via regulation of the PI3K/Akt and MAPK signaling pathways.

RESUMO

Social participation is a vital part of life and has multifaceted positive outcomes on personal health and wellbeing. Social participation or the lack thereof might have more profound psychological impacts on individuals in a collectivist culture than its counterpart. The current study explored personal and environmental barriers that have hindered the effective social participation of secondary students with visual impairments. Exploration addressed various activities in and outside school settings in Ethiopia and discussed findings in relation to the prevailing cultural orientation. In-depth semi-structured interviews were conducted to gather qualitative data on barriers to social participation of 17 secondary students with visual impairments in Addis Ababa, Ethiopia. The qualitative data were analysed thematically, yielding four major themes and identifying twenty sub-themes that limited the social participation of students with visual impairments, such as personal, attitudinal, sociocultural, and practical barriers. The study showed a range of barriers that participants experienced related to social participation, the criticality of cultural orientation in providing context to understand the impacts of social participation, and the need for future research in the area.

RESUMO

This study aimed to (1) explore the configuration of vocational identity status among emerging adults with and without hearing impairment using latent profile analysis, and (2) investigate the relationships between vocational identity status and self-esteem and subjective well-being. In total, 408 students without disabilities and 432 with hearing impairments from two Chinese higher institutions participated in the study. The Vocational Identity Status Assessment, Rosenberg Self-Esteem scale, Satisfaction with Life Scale, and Positive and Negative Affect were used to assess the major variables. The results derived five latent profiles (achieved, foreclosed, searching moratorium, undifferentiated, and diffused) of vocational identity in the present sample. The students were over-represented in undifferentiated profiles and under-represented in achieved and foreclosed ones. Hearing impairment significantly affected vocational identity status profile membership. The results showed that emerging adults with achievement and foreclosure statuses displayed healthy psychological outcomes, having the highest self-esteem, life satisfaction, and positive affect, and the lowest negative affect. In contrast, the diffused group showed the most disturbing pattern with the lowest self-esteem, life satisfaction, and positive affect, and the highest negative affect. The research findings reveal some notable issues in vocational identity status for emerging Chinese adults, raising concerns about the influence of hearing impairment on vocational identity formation, and provide implications for Chinese society to facilitate college students' career development process to promote their vocational identity status and enhance their self-esteem and subjective well-being.

RESUMO

This study explores the psychometric properties of Self-Determination Inventory: Student Report (SDI:SR) in students with intellectual and developmental disabilities (IDD) and without disabilities in China. The paper-and-pencil version of SDI:SR Chinese Translation (SDI:SR Chinese) was used to explore self-determination across students with IDD (n = 245) and students without disabilities (n = 315) from 16 schools across six cities in China. We examined the factor structure of the measure, conducted analysis of measurement invariance, and compared the latent means across students with IDD and without disabilities. Findings suggest that the data fit a one-factor model better than a three-factor model. We found greater variability in self-determination among students with IDD than students without disabilities. However, the two groups did not differ in latent means.

RESUMO

BACKGROUND: School-to-work transition programmes play a crucial role in the achievement of post-secondary outcomes for young adults with intellectual disability (ID). Although special education in China has progressed in the last two decades, systematically planned transition education and services are not usually available for Chinese school leavers. AIMS: The present study aimed to validate Kohler's Taxonomy of Transition Programming (KTTP) in the Chinese context for adolescents with ID. METHODS AND PROCEDURES: Five Chinese transition experts reviewed KTTP items, 14 Chinese transition teachers and 14 parents of adolescents with ID who would transition from school in the next 12 months were interviewed, and 329 transition teachers were surveyed. OUTCOME AND RESULTS: Most items in KTTP were found to be important and relevant to the Chinese context. Based on KTTP, a modified transition framework appropriate to the Chinese context was generated. CONCLUSIONS AND IMPLICATIONS: The Chinese transition framework may assist parents and professionals to better support adolescents with ID in China. Future validation checks of the framework will add confidence that the framework captures the essential components of effective transition practices appropriate in the Chinese context.
