RESUMEN
OBJECTIVE: This study aimed to investigate the correlation between positive psychological capital, post-traumatic growth, social support, and quality of life (QOL) in patients with systemic lupus erythematosus (SLE). METHODS: A cross-sectional study was conducted at the First Affiliated Hospital of Xinjiang Medical University from October 2022 to May 2023. A sample of 330 hospitalized SLE patients was selected for this study. The collected data included demographic information, the SLE disease activity index, the Positive Mental Capital Questionnaire, the Chinese version of the Post-Traumatic Growth Scale, the Social Support Rating Scale, and the Chinese version of the Lupus Quality of Life Scale. RESULTS: The QOL score among the 330 SLE patients was measured as M(P25, P75) of 105 (83.00,124.00). Positive psychological capital, post-traumatic growth, and social support demonstrated significant positive correlations with the QOL in SLE patients (p < 0.05). Multiple linear regression analysis revealed that literacy, disease level, disease duration, occupation, marital status, psychological capital, social support, and post-traumatic growth were influential factors associated with the QOL in SLE patients. CONCLUSION: Medical professionals should be attentive to the psychological well-being of SLE patients and should consider implementing early psychological interventions. These interventions are crucial for enhancing the QOL for individuals diagnosed with SLE.

Chemodynamic therapy (CDT) is a kind of anti-tumor strategy emerging in recent years, but the concentration of hydrogen peroxide (H2O2) in the tumor microenvironment is insufficient, and it is difficult for a single CDT to completely inhibit tumor growth. Here, we designed a CuS nanoparticles (NPs) and camptothecin (CPT) co-loaded thermosensitive injectable hydrogel (SCH) with self-supplied H2O2 for enhanced CDT. SCH is composed of CuS NPs and CPT loaded into agarose hydrogel according to a certain ratio. We injected SCH into the tumor tissue of mice, and under the irradiation of near-infrared region (NIR) laser at 808 nm, CuS NPs converted the NIR laser into heat to realize photothermal therapy (PTT), and at the same time, the agarose hydrogel was changed into a sol state and CPT was released. CPT activates nicotinamide adenine dinucleotide phosphate oxidase, increases the level of H2O2 inside the tumor, and realizes the self-supply of H2O2. At the same time, CuS can accelerate the release of Cu2+ in an acidic environment and light, combined with H2O2 generated by CPT for CDT treatment, and consume glutathione in tumor and generate hydroxyl radical, thus inducing tumor cell apoptosis. The SCH system we constructed achieved an extremely high tumor inhibition rate in vitro and in vivo, presenting a new idea for designing future chemical kinetic systems.
