Abstract

Drawing upon person–environment fit perspective, this study examines the joint and interactive influences of personal competence and environmental characteristics on the happiness of ageing adults around the period of COVID-19 pandemic. Data was collected in two rounds, before and during the pandemic, with 2,028 participants aged 55 years and older in Hong Kong. Personal competence encompassed financial status, physical health, and mental capital, while environmental characteristics included experiences of ageism, perceived social conditions, and age-friendly policies. Ordinary least squares regression was used to examine personal and environmental influences on happiness. Results indicated a significant decline in happiness following the onset of COVID-19 pandemic. Mental capital was found to have the strongest positive influence on happiness, followed by physical health, financial status, and social conditions. Mental capital mitigated the negative relationship between experiences of ageism and happiness. Practical interventions are informed to improve the well-being of ageing adults during pandemic.

Abstract

Objectives: This study investigates the associations between five types of childhood interpersonal trauma (CIT) and depression in mid-later life, as well as the mediation roles of social integration in the associations. Methods: Two waves of data from a nationally representative survey in China were used, with participants aged 45 years and older (N = 14,180). Measures of CIT included physical abuse, physical neglect, emotional neglect, bullying victimization, and exposure to interparental violence. Binary logistic regression and Karlson–Holm–Breen mediation analysis were used as statistical methods. Results: People who were bullied, physically abused, and witnessed interparental violence during childhood were more likely to develop depression in mid-later years. The associations between CIT and depression were mediated by satisfaction with marriage, satisfaction with children, and perceived social support. Discussion: Although CIT elevates the risk of depression in later life, effective interventions that strengthen integration across family and social domains could benefit mental health.

Abstract

To explore effective treatment of large abdominal malignancies in children complicated with abdominal compartment syndrome (ACS).Six children with large abdominal malignancies complicated with ACS were admitted to our department from January 2013 to January 2016, and the changes in their breathing, heart rate, oxygen saturation, abdominal circumference, bladder pressure, and urine output, as well as the treatment measures and outcomes, were retrospectively analyzed.The 6 children included 1 child with bilateral nephroblastoma, 1 child with abdominal alveolar rhabdomyosarcoma, 1 child with right ovarian malignant teratoma complicated with abdominal glioma, 1 child with abdominal malignant teratoma, 1 child with right nephroblastoma, and 1 child with left adrenal gland neuroblastoma. All patients were treated in a timely manner. The first 4 children underwent abdominal cavity decompression through surgical resection of the tumor, and the ACS was successfully cured allowing for follow-up care, whereas the last 2 patients failed to receive emergency surgery and eventually died due to the gradual aggravation of ACS.Decompression through surgical resection of the tumor is the only effective measure for treating large abdominal malignancies in children complicated with ACS.

Abstract

Upconversion nanoparticles (UCNPs) have made a significant and valuable contribution to photophysics and biomedicine, due to their specific spectroscopic characteristics. However, the ensemble spectroscopy of UCNPs is limited for the electronic behavior in average effect, which ignores the fact that the nanoparticles are heterogeneous. Towards the research focus on heterogeneous intrinsic structure, unique photophysical phenomena, and advanced applications, the optical characterization of single UCNPs are promoted to a frontier breakthrough of UCNPs community. Electronic behavior detection aimed at a single nanoparticle displays signals from the micro-structure of nanoparticles, while single nanoparticle spectroscopy offers clear insight into the interplay between intrinsic and extrinsic influences without noise, and subsequently gives instructions for the high quality preparation of UCNPs. Single nanoparticle optical characterization possesses a powerful capacity to explore the crystalline structure anisotropy related optical differences, or some unexpected unique optical phenomena at sub-micron and even nano-scale. In this review, the importance of single UCNPs characterization and single particle detection methods are overviewed, in which the considerable emphasis is placed on the specific spectroscopic study of single UCNPs Showing fantastic photophysical phenomena beyond ensemble measurement. Finally, this review identifies 1024 无 机 材 料 学 报 第 31卷 promising opportunities in which single UCNPs characterization technique can accelerate on-going research with a remarkable depth and breadth, facilitate discovery of upconversion nanoparticles that overcome fundamental limitations of current ensemble level.

Abstract

Aim Aberrant expression of Snail, a mediator of epithelial-mesenchymal transition (EMT), is crucial for cancer invasiveness and metastasis. Although hepatitis C virus (HCV) core protein has been implicated in hepatocarcinogenesis, the relationship between HCV core and Snail expression has not been clarified. Methods HepG2 and Huh7 stable cell lines were established by transfection with pcDNA-HCVc. HepG2-HCVc and Huh7-HCVc cells were co-administered with AG490. Cell migration and invasiveness were tested. STAT3 and Snail expression was analyzed by Real-time PCR and Western blot. Results We found that HCV core is capable of increasing Snail expression and inducing EMT in hepatoma cells. HCV core-induced Snail expression was accompanied by activation of signal transducer and activator of transcription 3 (STAT3), inhibition of STAT3 abrogated HCV core-induced Snail expression and EMT. Furthermore, chromatin immunoprecipitation showed that phosphorylated STAT3 directly binds to the Snail promoter. Conclusion Collectively, these results suggest that HCV core would play a role in hepatocellular carcinoma invasiveness and metastasis by activating the STAT3 pathway, increasing Snail expression and subsequently triggering EMT. These findings would advance the understanding of HCV-mediated invasiveness and metastasis, and might provide a new potential therapeutic target for HCV-related hepatocellular carcinoma.
